Description

U-shaped locking mechanism

Technical Field

The utility model belongs to the technical field of charging piles, and relates to a U-shaped locking mechanism installed on a side face.

Background

The existing lock catch mechanism is suitable for being installed on a planar door plate, but on a door plate product with a special-shaped inclined plane, the existing lock catch cannot lock the door plate after being installed on the side due to the fact that the door plate is required to be installed on the side due to attractive appearance. Meanwhile, when the door plate installed by the existing locking mechanism is in a locking state, the door plate is influenced by self weight, sagging phenomena of different degrees can occur, the surface difference between the door plate and the box body is increased, and the appearance of a product is influenced. And the sagging of door plant can lead to the joint strip on the door plant and the former pressfitting position on the side of bending of box skew downwards to increase the risk of leaking water when the outdoor use of product.

The existing locking mechanism is applicable to a charging pile, a sealing rubber strip is arranged on a door plate, a steel bolt lock tongue is in no-guide design, after the door plate rubber strip is contacted with a bending edge of a box body, a certain external force is required to be applied to the door plate to enable the lock tongue to hook a U-shaped hook on the door plate, meanwhile, a lock body handle can press the sealing rubber strip with a large closing force, so that the door is closed, otherwise, when the door is opened, the door plate is required to be opened, the external force is required to be applied to the door plate to enable the lock body handle to drive the steel bolt lock tongue to open the door plate, and when the lock is used, people with a certain arm force are required to finish the closing or opening of the door plate, so that the lock cannot be applicable to all people; the lock adopts the mode that general key was opened, and fail to realize keyless quick opening with low reliability.

Accordingly, there is a need for improvements in the art that overcome the shortcomings of the prior art.

Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

Examples

Referring to fig. 1-3, a U-shaped latch mechanism includes a latch base 6 disposed on a side of a case 1, and a latch handle 7 disposed on the latch base 6, the latch handle 7 being exposed outside the case 1. A steel bolt lock tongue 8 fixedly connected with a lock body handle 7 is arranged in the box body 1. The door plate 2 is provided with a U-shaped hook 3, and the U-shaped hook 3 corresponds to the position of the steel bolt lock tongue 8.

Specifically, one side of the door panel 2 is hinged to the box 1, and the opening of the box 1 is provided with a box folded edge 9 protruding outwards, and in this embodiment, the box folded edge 9 is shaped like a Chinese character 'kou'. One end of a hinge part connecting the door plate 2 and the box body 1 is locked on the box body folded edge 9, and the other end is fixed on the inner side of the door plate 2. When the door panel 2 is closed, the hinge cannot be seen from the outside, and the attractive appearance is good. The inner side of the door plate 2 is provided with a sealing rubber strip 4, the sealing rubber strip 4 corresponds to the box folded edge 9, and when the door plate 2 is closed, the sealing rubber strip 4 is abutted against the outer side face of the box folded edge 9. When the product is used outdoors, rainwater seeps downwards from the gaps between the door plate 2 and the box body 1, is blocked by the sealing rubber strip 4 and then is discharged from the two sides of the box body folded edge 9, and cannot enter the box body 1.

When the door plate 2 is closed, an operator rotates the lock body handle 7, so that the steel latch tongue 8 is clamped into the U-shaped hook 3 from bottom to top in a rotating way. The U-shaped hook 3 is fixed on the door plate 2, the steel bolt lock tongue 8 effectively plays a role in supporting the door plate 2, so that the sagging phenomenon of the door plate 2 caused by the existence of dead weight is prevented, and the influence on the appearance caused by the increase of the surface difference between the door plate 2 and the box body 1 is avoided; meanwhile, the pressing position of the sealing rubber strip 4 corresponds to the position of the folded edge 9 of the box body, so that the risk of water leakage during outdoor use of the product is reduced.

In this embodiment, the upper end of the bolt tongue 8 has a guiding angle 5, the guiding angle 5 is narrow at the top and wide at the bottom, and has a guiding inclined plane, which is the contact surface between the guiding angle and the U-shaped hook. When the door plate 2 is closed to a certain angle, the top end of the steel bolt lock tongue 8 contacts and hooks the U-shaped hook 3. The steel bolt lock tongue 8 is clamped into the U-shaped hook 3 in a rotating way from bottom to top, and a guide inclined plane on the guide angle 5 is contacted with the U-shaped hook 3 to guide the steel bolt lock tongue 8 to be clamped into the U-shaped hook 3. The operator drives the steel latch tongue 8 to be easily drawn into the U-shaped hook by means of the lever force when the lock body handle 7 rotates, and the door plate locking action is completed. On the contrary, when needing to open the door, lock body handle 7 drives steel bolt spring bolt 8 and easily draws through guide angle 5, can open door plant 2, and at this in-process door plant 2 need not to exert external force, rotates door lock body handle 7 and can easily close and open door plant 2, realizes all crowd's application, labour saving and time saving, and the product customer experience is felt to be excellent, promotes market competition.

In this embodiment, a key jack 10 and a code disc 11 are mounted on the lock handle 7, and the code disc adopts a mechanical code disc. Since the key insertion hole and the code wheel realize the lock switch belong to the prior art, the detailed description thereof is not provided here. The design theory of two-way unlocking of a lock is adopted in the embodiment, the mechanical coded disc is used for realizing keyless quick unlocking, the lock is matched with a key number to unlock the lock by a key, the mutual unlocking rate is low, and the mechanical coded disc is convenient, quick, safe and reliable.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
