Description

Automatic locking and unlocking device

Technical Field

The application belongs to the technical field of equipment locking and unlocking, and particularly relates to an automatic locking and unlocking device.

Background

The quick locking device has many structural forms in the aspect of quick locking of equipment or ropes, generally adopts a mechanical hook, manually opens the hook and then locks goods or equipment, and manually opens the hook harder, and particularly when heavy equipment is used, the mechanical hook can not be opened manually, so that great potential safety hazards exist, the use is not convenient enough, the reliability and the safety are low, the economy is poor, and the quick locking device is easily limited by external conditions.

Disclosure of Invention

It is an object of the present application to provide an automatic locking and unlocking device to solve or mitigate at least one problem of the background art.

The technical scheme of the application is as follows: an automatic locking and unlocking device comprising:

the mounting seat is fixedly connected to the mounting surface, a rectangular cavity is formed in the lower surface of the mounting seat in an upward direction, and a rectangular through groove in the front-back direction is formed in the lower surface of the mounting seat;

rotatory hook, the upper portion of rotatory hook is the barred body, the lower part is the hook-shaped body, rotatory hook passes through the rotatable pin joint of fixed pin in the rectangular cavity of mount pad, and wherein, the position of fixed pin is set up to: under the non-stressed state, the hook body of the rotating hook 3 is hidden in the rectangular cavity and does not extend into the rectangular through groove, and the strip body part extends into the rectangular through groove;

after the annular connecting piece stretches into the rectangular through groove, the hook-shaped body of the rotating hook is extruded through the connecting piece, so that the hook-shaped body enters the rectangular through groove, and the connecting piece is locked.

Furthermore, the mounting seat is of a rectangular structure.

Furthermore, the rectangular cavity is perpendicular to the rectangular through groove.

Further, the thickness of the strip-shaped body and the hook-shaped body is smaller than the width of the rectangular cavity.

Further, the connecting piece is a rectangular or circular ring-shaped structure, and the cross section of the connecting piece comprises a circle or a square.

According to the device, the gravity center position of the rotating hook is utilized, so that the rotating hook automatically rotates after being collided by the connecting piece, and the connecting piece automatically rotates and returns when not collided, and therefore the quick automatic locking and automatic unlocking capabilities of the connecting piece are realized; through the rectangular through groove combination form that adopts rotatory hook, fixed pin and mount pad, receive the restraint of rotatory hook self focus position, make the locking mouth that the rectangle of mount pad led to the groove remain the state of opening all the time, need not personnel and open specially when the locking connecting piece, reduced personnel's operation, improve availability factor and security.

Drawings

In order to more clearly illustrate the technical solutions provided by the present application, the following briefly introduces the accompanying drawings. It is to be expressly understood that the drawings described below are only illustrative of some embodiments of the invention.

Fig. 1 is a schematic structural view of an automatic locking and unlocking device according to the present application.

Fig. 2 is a schematic view of the locking process of the automatic locking and unlocking device of the present application.

Detailed Description

In order to make the implementation objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.

As shown in fig. 1 to 2, the present application provides an automatic locking and unlocking device including a mount 1, a fixing pin 2, a rotating hook 3, and a connecting member 4.

In this embodiment of the present application, the mounting base 1 has a rectangular structure. The upper surface fixed connection of mount pad 1 is on

installation face

11, and 1 lower surface of mount pad is opened upwards has a rectangle cavity 12, and simultaneously, the lower surface of mount pad 1 is opened has a fore-and-aft direction's rectangle to lead to groove 13, and rectangle leads to groove 13 and rectangle cavity 12 is perpendicular.

The rotating hook 3 is J-shaped, and has a strip-shaped body 31 at the upper part and a hook-shaped body 32 at the lower part. The rotating hook 3 is rotatably pivoted in the rectangular cavity 12 of the mounting seat 1 through the fixing pin 2. The thickness of the strip 31 and the hook 32 is smaller than the width of the rectangular cavity 12, so that the rotating hook 3 can smoothly rotate in the rectangular cavity 12.

Wherein the position of the fixing pin 2 is set as: in the non-stressed state, the hook body 32 of the rotating hook 3 is hidden in the rectangular cavity 12 and does not extend into the rectangular through groove 13, and the strip body 31 partially extends into the rectangular through groove 13. Thus, in the rest state, the center of gravity of the rotating hook 3 is located directly below the fixing pin 2, and the strip 31 at the lower portion of the rotating hook 3 is located on the left side of the rectangular through groove 13 of the mount 1.

The connecting piece 4 is a rectangular or circular ring structure, and the section of the connecting piece can be circular or square and the like. The upper part of the connecting element 4 is located in the rectangular through slot 13 of the mounting 1 and fits over the hook-shaped body 32 of the rotating hook 3.

During the use, stretch into the rectangle that mount pad 1 with the upper portion of connecting piece 4 and lead to the groove 13 in, continue the bar body that upwards remove connecting piece 4 and can withstand rotatory hook 3, make rotatory hook 3 clockwise rotation until the structure body 32 of rotatory hook get into the rectangle that mount pad 1 lead to the groove 13 in, after the rectangle that mount pad 1 was led to the groove 13 bottom in the upper end of connecting piece 2 top, drop-down fast, make the upper portion cover of connecting piece 4 in the hook body 32 of rotatory hook 3, and then with connecting piece 4 locking in the rectangle that mount pad 1 leads to the groove 13, thereby reached quick automatic locking effect.

When the locking is removed to needs, with the upper end rebound of connecting piece 4, after the rectangle that the upper end of connecting piece 4 pushed up mount pad 1 led to the groove 13 bottom, slowly drop-down, rotatory hook 3 receives self focus to influence, anticlockwise rotation, the focus is located fixed pin 2 under, the hook body 32 of rotatory hook 3 leaves the rectangle that mount pad 1 and leads to the groove 13, connecting piece 4 no longer receives the hook body 32 of rotatory hook 3 to restrict, thereby realized that connecting piece 4 leads to the groove 13 in the rectangle of mount pad 1 automatic unblock function.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
