Detailed Description

The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present embodiment provides a case 1, a mounting rail 3 for mounting a self-locking device and a detecting mechanism 2 for pulling the self-locking device are disposed in the case 1, the detecting mechanism 2 includes a sliding rod 24, a sliding block 22 slidably connected to the sliding rod 24, and a driving component for driving the sliding block 22 to reciprocate along the sliding rod 24, and the mounting rail 3 is parallel to the sliding direction of the sliding block 22; a lantern ring 23 used for being connected with a connecting ring of the self-locking device is arranged on the sliding block 22;

referring to fig. 3, before detection, the self-locker 4 is required to be mounted on the mounting rail 3, the self-locker 4 can slide along the mounting rail 3 in the non-self-locking direction, and the connecting ring of the self-locker 4 is connected to the lantern ring 23 through a rope, which should be noted that the rope is just straightened and cannot be loosened; when the sliding block 22 slides left and right, the self-locking device 4 is pulled to slide through the rope, and in one direction, the sliding block 22 cannot pull the self-locking device 4 to slide, so that the self-locking device 4 is qualified, and if the sliding block can slide in two directions, the self-locking device 4 cannot realize the self-locking function.

It should be noted that the application scenarios of the self-locking device 4 are different, and therefore the shape of the self-locking portion thereof is also different, in order to adapt to different self-locking devices, the mounting rail 3 comprises a rope 32 and a rail 33, the rope 32 is parallel to the rail 33, and the self-locking device 4 is clamped on the rope 32 or the rail 33; the cross-section of the track 33 is square and the cross-section of the rope 32 is circular, and the two are used for detecting different types of self-locking devices.

Referring to fig. 1 and 2, in this embodiment, the rope 32 and two ends of the track 33 are fixedly provided with a turntable 31, and the turntable 31 is rotatably connected with the inner wall of the box body 1; the rotary table 31 is provided with a plurality of clamping grooves, the clamping grooves are provided with openings along the outer side of the radial direction of the rotary table 31, the inner wall of the box body 1 is provided with a slide rail 11, the slide rail 11 extends towards the clamping grooves, the slide rail 11 is slidably connected with a clamping block 34 used for limiting the rotation of the rotary table 31, and when the slide rail 11 is aligned with the clamping grooves, the clamping block 34 is slidably connected with the clamping grooves; the distance between the rope 32 and the track 33 and the circle of the rotary table 31 is equal, the rope 32 and the track 33 are located on two sides of the circle center, two clamping grooves are formed in the rotary table 31 and located on the opposite sides of the rotary table 31, when the clamping block 34 is located in the clamping grooves, the rotary table is limited to rotate, the clamping block 34 is drawn out, the rotary table 31 can be rotated, the rotary table 31 can rotate 180 degrees, and the positions of the rope 32 and the track 33 can be changed; assuming that the clamping block 34 is initially positioned in one of the clamping grooves, and the rope 32 and the sliding block 22 are positioned on the same horizontal line, the self-locking device can be mounted on the rope 32 for detection; the fixture block 34 is drawn out, the rotary disc 31 is rotated, the fixture block 34 is clamped into the other clamping groove, the rotary disc 31 rotates 180 degrees at the moment, the track 33 and the sliding block 22 are located on the same horizontal line, and the self-locking device can be installed on the track 33 for detection at the moment; the purpose of the turntable 31 is to reduce the component of the pulling force and prevent the collar 23 from being pulled out.

Referring to fig. 1, in the present embodiment, the driving assembly includes a screw 21 and a motor for driving the screw 21 to rotate, the sliding block 22 is in threaded connection with the screw 21, the screw 21 is axially parallel to the sliding rod 24, and the motor drives the screw 21 to rotate forward and backward, so that the sliding block 22 reciprocates along the axial direction of the screw 21, thereby realizing the detection of the self-locking device in two directions.

In another embodiment (not shown), the driving assembly includes a pneumatic push rod for pushing the slider 22 to reciprocate, and the slider 22 is pushed by the pneumatic push rod to reciprocate horizontally, so as to achieve the same function as the first embodiment.

It is noted that if the self-locking force of the self-locking device exceeds the force exerted on the self-locking device, the motor idle/pneumatic push rod stops working, and the specific implementation mode is as follows: the screw 21 is excessively matched with the output end of the motor, when the self-locking device is locked, the slide block limits the rotation of the screw 21, and the screw 21 slips with the output end of the motor; the pneumatic pushing rod is that the air pressure can not push the sliding block 22, so that the sliding block 22 stops moving.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
