The left and right ends of the two are respectively connected to the ends of the longitudinal side walls of the corresponding end cap 102 as a whole. Thus, not only can the whole formed by the support beam plate 500 and the two end caps 102 present a U-shaped structure similar to the L-shaped longitudinal ends, so as to enhance the structural stability between the two locks, but also The support beam plate 500 can be fitted into a tank such as a luggage body to enhance the structural stability of the tank itself, prevent the tank from being deformed, and provide ample and stable assembly space for the handle part such as a booster body.

As a preferred solution, in order to be able to lock the corresponding components firmly with the lock, referring to FIG. 7 and FIG. 8, a plurality of hanging holes 501 are provided in the support beam plate 500. As a result, after fitting the handle part such as the booster body into the groove body of the luggage body, the hanging bracket provided on the handle part can be hung on the hanging hole 501, and then locked with the lock.

Embodiments of the invention

In order to maximize the structure of the entire locking device and expand its application range, the manipulator 400 of this embodiment can be implemented in different structural forms according to actual conditions, such as:

The holding state is stable (according to the difference in the setting direction of the abutting slope, the locking spring can be composed of a tension spring and a compression spring respectively provided on the upper and lower ends of the slider). When unlocking is required, the second sliding handle 409 can be operated in the reverse direction. At this time, under the elastic force of the first unlocking compression spring 410, the lock rod 300 can be assisted to be received into the lock housing 100, thereby achieving the effect of saving effort.

In the implementation of the second embodiment, each lock can be provided with at least two lock rods 300 arranged in parallel up and down, and all the lock rods 300 can simultaneously correspond to a second sliding handle 409 or respectively correspond to a second sliding handle 409 ( That is: each lock rod 300 corresponds to a second slider 407 and a first unlocking compression spring 410, and each second slider 407 can be connected to a second sliding handle 409 or using a second sliding handle. 409 directly connects all the second sliding blocks 407 into a whole); multiple lock rods 300 can be used to enhance the locking ability of the lock itself.
