The inner vertical part (8) and the outer vertical part (9) are respectively connected to both ends of the straight connecting part (5);

The lock return spring (5) is arranged in the space surrounded by the outer vertical part (9), the side surface and the bottom surface of the rail part (3) and the straight connecting part (7), and The lock return spring (5) is axially parallel to the side of the base (1);

The top outer edge of the inner vertical part (8) is provided with an arc-shaped guide surface, and the rear end edge of the arc-shaped guide surface extends outward to the vertical part (9) to form a hook part, so as to facilitate insertion or extraction of the The lock (10) on the cam handle (2) realizes the limit fixing or unlocking of the cam handle (2);

The inner vertical part (8) is vertically fixed on the straight connecting part (7) by pins (11).

The above-mentioned installation rail for the sight also includes a rail pad (12) installed on the top surface of the base (1), connected by the top board (13), the bottom board (14) and the top board (13) and the bottom board respectively. The left side plate (15) and the right side plate (16) of the left and right corresponding ends of (14) constitute;

The left and right edges of the top plate (13) are provided with guide rails (17, 18) that are snapped together with the sight;

The bottom plate (14) is fixedly connected with the base (1) by screws.

The utility model has the following advantages: the operation is more ergonomic, convenient and fast, and can meet the adjustment of the height of the sight.

The utility model is described in detail below in conjunction with accompanying drawing and embodiment.

Detailed ways

Figures 1 and 2 are a mounting rail that can be used in conjunction with various inner red dot sights (as shown in Figure 4, the inner red dot sight is installed on the mounting rail), including base 1 and one side of the mounting base The cam handle 2 and the locking mechanism for fixing the cam handle 2, the locking mechanism includes a rail part 3, a sliding lock 4 and a lock reset spring 5 clamped in the rail part 3; the rail part 3 is set At the rear end of the base 1 , the parallel track opening 6 of the rail portion 3 is parallel to the side of the base 1 .

The sliding lock 4 is composed of a straight connecting portion 7 parallel to the bottom surface of the rail portion 3 (parallel to the side of the base 1), an inner vertical portion 8 and an outer vertical portion 9 perpendicular to the bottom surface of the rail portion 3; the inner vertical portion 8 and the outer vertical portion 9 are respectively connected to two ends of the straight connecting portion 7 .

As shown in FIG. 2 , the lock return spring 5 is arranged in the space surrounded by the outer vertical part 9 , the side surface of the rail part 3 , the bottom surface and the straight connection part 7 , and the axial direction of the lock return spring 5 is parallel. on the side of base 1.

The top outer edge of the inner vertical part 8 is provided with an arc-shaped guide surface, and the rear end edge of the arc-shaped guide surface extends outward to the vertical part 9 to form a hook, so as to insert or pull out the lock on the cam handle 2 In 10, the cam handle 2 is realized to be fixed or unfixed; the inner vertical part 8 is vertically fixed on the straight connecting part 7 by the pin 11, specifically, the top of the inner vertical part 8 is provided with a screw hole downwards, Screw holes are provided at corresponding positions of the straight connecting portion 7, and the fixed connection is realized through the pin 11.

This kind of mounting rail is different from the existing ones in that when the cam handle 2 is opened, the sliding lock 4 is pushed toward the cam portion of the cam handle 2, so that the arc guide surface of the inner vertical portion 8 is far away from the cam handle 2. The rear edge of the lock 10 on the upper side, so that the hook part is separated from the release of the lock 10, and the end of the cam handle 2, that is, the pulling part 12 at the free end, can be pushed upward to realize the release of the limit of the cam handle 2. This operation Compared with the traditional method of pulling backwards to open the lock, when contacting the locking limit, you only need to push the sliding lock 4 forward, and when unlocking the limit, you only need to buckle the cam handle to release the lock. The lock 10 is introduced to achieve fastening with the arc-shaped guide surface at the top and rear end of the inner vertical part 8. This operation conforms to people's inertial operating habits, has the advantage of convenient operation, and is conducive to rapid operation.

In order to meet the needs of sight height adjustment, this embodiment provides the top plate 13, the bottom plate 14 and the left side plate 15 and the left side plate 15 and The rail spacer formed by the right side plate 16 is fixedly connected with the above-mentioned installation rail by screws, and the top plate 13 of the rail spacer is provided with guide rails 17, 18 that can be snapped together with the sight.

Through the rail spacer, it can be realized that when the height needs to be adjusted, the rail spacer only needs to be fixedly installed on the top surface of the installation rail, and then the sight is clamped on the top of the rail spacer through the guide rails 17 and 18 The surface can be shown in Figure 4.
