[0019] Figure 2 This is an internal structural diagram of a new type of lock hook lock body provided by an embodiment of the utility model;
[0020] Figure 3 This is an internal structural diagram of a new type of lock hook lock body provided by an embodiment of the utility model;
[0021] Figure 4 It is an exploded view of a new type of lock hook lock body provided by an embodiment of the utility model. Specific implementation method:
[0022] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0023] like Figures 1 to 4As shown, this embodiment provides a new type of lock hook lock body, including a lock shell 1, a lock snap nail 2 is fixed in the lock shell 1, both ends of the lock snap nail 2 are connected to the lock shell 1 for fixation, a rotatable lock hook 3 is sleeved on the lock snap nail 2, and a push piece 4 is arranged at both sides of the lock hook 3 in the lock shell 1. In order to protect the lock hook 3 from being easily deformed, the push piece 4 is provided with an avoidance groove 41 through which the lock snap nail 2 passes, and the avoidance groove 41 is left for the push piece 4 to move up and down, wherein a push rod 5 is fixedly arranged between the two push pieces 4, and a push groove 31 is arranged on the lock hook 3. The push rod 5 passes through the push groove 31 and is used to push the lock hook 3 to rotate. The lock hook 3 is pushed and rotated by the push rod 5 on the push piece 4 that moves up and down, which can improve stability, prevent deformation, and extend the service life.
[0024] Preferably, two first spring columns 11 are provided in the lock housing 1, the push sheet 4 is located between the first spring columns 11, a second spring column 42 is provided on the push sheet 4, and a spring is provided between the first spring column 11 and the second spring column 42. The function of the spring is to generate pressure during the opening or closing process, and it is not easy for the push sheet 4 to slide due to gravity.
[0025] Preferably, a push block 6 is provided at the end of the push sheet 4 , and the push block 6 is fixed between two push sheets 4 . The push block 6 can enhance firmness and is not easily deformed.
[0026] Preferably, a lock head 7 is provided on the lock housing 1 , and a swinging portion 71 is provided on the lock head 7 . The swinging portion 71 rotates to push the pushing block 6 to move the pushing sheet 4 up and down.
[0027] Preferably, a sleeve 21 is provided between the locking nail 2 and the locking hook 3, and the sleeve 21 can reduce the friction between the locking nail 2 and the locking hook 3, so that the locking nail 3 can rotate more flexibly.
[0028] Preferably, two locking hooks 3 are provided and are symmetrically placed. In the upper locking hook 3, the push rod 5 is located on the left side of the locking nail 2, and in the lower locking hook 3, the push rod 5 is located on the right side of the locking top 2.
[0029] like Figure 3 As shown, a certain thrust will be generated during the pushing process of the push piece 4 to push the shell, which is easy to damage the shell. Therefore, a buffer block 12 is provided at the end position of the lock shell 1. The buffer block 12 is provided at both ends of the lock shell 1 to reduce the thrust and increase the service life.
[0030] Preferably, a lining plate 8 is provided on the side of the lock housing 1 , and a through hole 81 is provided on the lining plate 8 through which the lock hook 3 extends.
[0031] Preferably, the lock housing 1 includes an upper lock housing 13 and a lower lock housing 14 .
[0032] In the prior art, the lock hook and lock body are driven to rotate by a metal paddle, which is prone to deformation of the metal paddle, resulting in failure to start or close. By arranging push pieces 4 on both sides of the lock hook 3 in the lock shell 1, when the swinging portion 71 of the lock head 7 rotates, the push block 6 is pushed to move the push piece 4 up and down. During the upward movement of the push piece 4, the push rod 5 passes through the push groove 31 to rotate the lock hook 3, thereby opening or closing the lock body. This can improve stability, prevent deformation, and extend service life.
[0033] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement methods and are included in the protection scope of the present invention.
