Wherein, the inner side of the first hoop body 1 and the inner side of the second hoop body 2 are respectively provided with a pre-clamping piece 9 and a fixing plate 10, and the pre-clamping piece 9 comprises a circular arc-shaped clamping plate 91; grooves 92 are formed in the inner side wall of the first hoop body 1 and the inner side wall of the second hoop body 2, and the clamping plate 91 is mounted on the grooves 92 through buffer springs 93; after the fixing plate 10 is fixedly adhered to the inner side walls of the first hoop body 1 and the second hoop body 2 through an adhesive and the clamping hook piece 5 is clamped into the groove, the inner surface of the clamping plate 91 contacts the surface of the cable, the fixing plate 10 does not contact the cable, at the moment, the clamping plate 91 reduces the acting force between the fixing plate and the cable through the buffer spring 93, so that the cable can longitudinally move, the clamping plate 91 only limits the transverse swing of the cable, and the buffer spring 93 can absorb the transverse acting force of the cable; after the back-drawing is finished, the first hoop body 1 and the second solid are further clamped through the locking assembly 7, the clamping plate 91 is contracted into the groove 92, the inner wall of the fixing plate 10 is attached to the cable, the cable is clamped through the fixing plate 10, the cable cannot longitudinally move, the clamping plate 91 also clamps the cable under the acting force of the buffer spring 93, and further the cable is limited to longitudinally move.
The inner wall of the clamping plate 91 is a smooth surface, and friction force between the clamping plate and the surface of the cable is reduced when the clamping plate is pre-clamped; the fixing plate 10 is made of rubber materials, and anti-skid patterns are arranged on the inner surface of the fixing plate, so that friction between the fixing plate 10 and a cable can be increased, and the fixing effect is improved.
Specifically, the locking assembly includes a pressing member 71, a lock catch 72, and a lock hook 73; the pressing piece 71 is rotatably connected to the clamping hook piece 5; the lock catch 72 comprises a mounting rod 731 and a U-shaped lock rod 732, the mounting rod 731 is rotatably mounted on the pressing piece 71, one end of the U-shaped lock rod 732 penetrates through the mounting rod 731, and the length of the U-shaped lock rod 732 penetrating through the mounting rod 731 is adjustable; the latch hook 73 is disposed at the top end of the boss 8, and can be hooked with the U-shaped latch lever 732. The locking component rotates along with the rotation of the clamping hook piece 5, and when the connection points of the pressing piece 71, the support piece 4, the hinge shaft of the pressing piece 71 and the U-shaped lock rod 732 and the lock hook 73 are in a straight line, the locking component can achieve a self-locking effect, so that the first hoop body 1 and the second hoop body 2 are locked. When the locking assembly needs to be opened, the operator rotates the pressing member 71 clockwise, the pressing member 71 drives the mounting rod 731 to rotate clockwise, and then drives the U-shaped lock rod 732 to move rightward to slide out of the lock hook 73, thereby achieving the unlocking effect of the locking assembly. Through using above-mentioned locking element, the operator need not appurtenance and single hand operation can accomplish the fastening of cable for the dismouting of cable is simple, convenient, only needs single can accomplish the fixed of cable within 1 minute.
Two adjusting nuts 733 are connected to the penetrating portion of the U-shaped lock rod 732 in a threaded manner, and the two adjusting nuts 733 are located at two sides of the mounting rod 731 respectively. By adjusting the two adjusting nuts 733, adjusting the length of the U-shaped lock bar 732, adapting to cables of different diameters, and adjusting the clamping force.
Working principle:
opening the angle between the first hoop body 1 and the second hoop body 2, placing the cable into the installation space 3, rotating the connecting plate 51 to enable the hook part 55 at one end of the movable plate 52 to enter the limiting groove 56, limiting the hook part 55 through the limiting groove 56, enabling the first hoop body 1 and the second hoop body 2 not to open, at this time, limiting the left and right random swing of the cable by the clamping plate 91, sleeving the U-shaped lock rod 732 on the lock hook 73 after the back drawing is completed, pressing the pressing piece 71 downwards, enabling the separation angle between the first hoop body 1 and the second hoop body 2 to be reduced, enabling the fixing plate 10 to clamp the cable, and fixing the cable. Therefore, when the cable is drawn back, the first hoop body 1 and the second hoop body 2 are locked through the clamping hook piece 5 to pre-clamp the cable, so that the cable can be prevented from swinging randomly, the manual adjustment position is reduced, and the efficiency of the whole cable installation process is improved.
