Adopt the closing lid self-locking mechanism of this application, the hasp is dialled to the lateral sliding hand, and accessible inclined plane contact promotes automatic hasp in step and moves down, makes automatic hasp and quick-witted case box break away from the locking and realize opening of side door closure, when closing the side door closure, loosens the hasp of dialling the hand, and at this moment, the hasp of dialling the hand resets with automatic hasp respectively under the spring action that corresponds the spring, can realize the automatic locking that the side door closure was closed, has ensured the reliability and the leakproofness that the side door closure was closed.

Description

Side door cover closing self-locking mechanism

Technical Field

The utility model relates to a locking technical field is closed to the door closure, concretely relates to side door closure closes and covers self-locking mechanism.

Background

Communication, power supply equipment and other products generally comprise a chassis and an internal structure, and in order to facilitate maintenance, replacement of parts and the like, a side door cover of the chassis is sometimes designed to be openable and closable.

At present, when the side door closure is closed and locked, because only the hand-operated lock catch is designed, so the locking is required to be manually operated, and in the actual process, the side door closure is often forgotten to be locked, so that the door closure is not closed tightly in transportation or use, so that external water vapor or sand dust enters the box body to corrode an internal structure, further, the heat-conducting property of the equipment is reduced, and the short circuit and other faults are avoided, and even the equipment is scrapped.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a side door closure closes and covers self-locking mechanism to realize the automatic locking after the side door closure closes the lid, ensure the reliability and the tightness that the side door closure closed.

The utility model discloses an above-mentioned problem is solved to following technical means: the utility model provides a side door lid closes and covers self-locking mechanism, includes quick-witted case box and through hinge and quick-witted case box articulated side door lid, be provided with on the side door lid with the side door lid lateral sliding fit hand dial lock catch, be used for the hand to dial the horizontal spring that the lock catch slides and resets, with the side door lid longitudinal sliding fit automatic lock catch and be used for the automatic lock catch to slide the vertical spring that resets, dial through the inclined plane contact between lock catch and the automatic lock catch with the hand and be connected, automatic lock catch locks with quick-witted case box when upwards resetting.

Furthermore, a transverse guide groove used for sliding guide of the hand-pulling lock catch is formed in the side door cover.

Furthermore, the left side and the right side of the bottom of the side door cover are hinged with the case body through hinges.

Furthermore, the hand-poking lock catch is in contact connection with the automatic lock catch through a 45-degree inclined plane.

Furthermore, a longitudinal guide structure for automatic lock sliding guide is arranged on the side door cover.

Further, the longitudinal guide structure is a longitudinal guide rail or a longitudinal guide groove.

The utility model has the advantages that: the utility model provides a side door lid closes and covers self-locking mechanism, include quick-witted case box and through hinge and quick-witted case box articulated side door lid, be provided with on the side door lid and dial the hasp with the side door lid lateral sliding fit hand, be used for the hand to dial the horizontal spring that the hasp slides and resets, with side door lid longitudinal sliding fit automatic catch and be used for the vertical spring that the automatic catch slides and resets, dial through the inclined plane contact between hasp and the automatic catch with the hand, automatic catch locks with quick-witted case box when upwards resetting. Adopt the closing lid self-locking mechanism of this application, the hasp is dialled to the lateral sliding hand, accessible inclined plane contact promotes automatic hasp and moves down in step, makes automatic hasp and quick-witted case box break away from the locking and realize opening of side door closure, when closing the side door closure, loosens the hasp of dialling the hand, and at this moment, the hasp of dialling the hand resets with automatic hasp respectively under the spring action of lateral spring and vertical spring, can realize the automatic locking that the side door closure was closed, has ensured the reliability and the tightness that the side door closure was closed.

Drawings

The invention is further described with reference to the following figures and examples.

Fig. 1 is a schematic front view of an embodiment of the present invention;

fig. 2 is a schematic rear view of the embodiment of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, the side door cover closing self-locking mechanism of the present embodiment includes a chassis body 1 and a side door cover 5 hinged to the chassis body through a hinge 3, and specifically, the left and right sides of the bottom of the side door cover 5 are hinged to the chassis body 1 through the hinge 3. Be provided with on the side door closure 5 with 5 lateral sliding fit's of side door closure hand dial lock catch 7, be used for hand dial lock catch 7 slide reset horizontal spring 2, with 5 longitudinal sliding fit's of side door closure automatic lock catch 6 and be used for automatic lock catch 6 slide reset vertical spring 4, through 45 inclined planes 8 contact connection between hand dial lock catch 7 and the automatic lock catch 6, automatic lock catch 6 locks with quick-witted case box 1 when upwards resetting.

Preferably, a transverse guide groove 9 for guiding the hand-pulling lock catch 7 in a sliding manner is formed in the side door cover 5, so that the sliding of the hand-pulling lock catch 7 is limited and guided.
