DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1 As shown, the utility model provides an automatic detection device for a lock. In order to realize automatic detection of the lock and the detection device and to complete the convenient adjustment of the detection device when the two-side detection is completed during the detection process of the lock, a base 1 is proposed, one side of the base 1 is rotatably connected with a rotating frame 2, one side of the rotating frame 2 is fixedly connected with a detection frame 3, one side of the detection frame 3 is provided with a first detection groove 4, and the other side of the detection frame 3 is provided with a second detection groove 5, one side of the rotating frame 2 is provided with a driving mechanism for moving and driving the lock during the detection process, one side of the base 1 is provided with a traction mechanism for rotating and pulling the rotating frame 2, and a limiting mechanism for limiting the rotation of the rotating frame 2 is provided between the base 1 and the detection frame 3.

[0019] like Figure 1 As shown, in order to realize the automatic movement of the lock head instead of the traditional manual pushing method when the lock head moves in the detection frame 3, a driving mechanism is proposed, which includes a driving groove 11 arranged on one side of the rotating frame 2, and a driving roller 12 is rotatably connected in the driving groove 11. A traction motor 13 is provided at one end of the driving roller 12, and the output shaft of the traction motor 13 is fixedly connected to the rotating shaft of the driving roller 12.

[0020] like Figure 1 As shown, in order to enhance the stability of the lock during the moving detection process, it is proposed that a plurality of connecting grooves 9 are opened on one side of the rotating frame 2, and a plurality of contact rollers 10 arranged at equal intervals are rotatably connected in the connecting grooves 9.

[0021] like Figure 2 As shown, in order to realize convenient adjustment of the detection surface when the detection frame 3 detects different detection surfaces of the lock, a traction mechanism is proposed, which includes a connecting frame 6 fixedly connected to one side of the base 1, one side of the connecting frame 6 is rotatably connected with a rotating shaft, the rotating shaft is fixedly connected to the detection frame 3, one side of the connecting frame 6 is fixedly connected to a mounting plate 7, one side of the mounting plate 7 is fixedly connected to a driving motor 8, and the output shaft of the driving motor 8 is fixedly connected to the rotating shaft.

[0022] like Figure 3 As shown, in order to increase the stability of the rotating frame 2 and the detection frame 3 when adjusting the detection surface, a limiting mechanism is proposed, including two limiting frames 14 fixedly connected to one side of the detection frame 3, one side of the limiting frame 14 passes through a limiting shaft 16 that is rotatably connected, one side of the base 1 is provided with a limiting groove 15, the limiting shaft 16 is rollingly connected in the limiting groove 15, the side wall of the limiting shaft 16 is fixedly connected to a limiting plate, and the limiting plate is slidably connected to one side of the base 1.

[0023] like Figure 1-3As shown, when in use, first, under the limiting action of the limiting shaft 16, the limiting groove 15 and the limiting frame 14, the initial positions of the detection frame 3 and the rotating frame 2 on the base 1 are maintained as shown in FIG. Figure 1 As shown, at this time, the limiting roller 16 is in close contact with one side of the limiting groove 15, which ensures that the second detection groove 5 and the lock are relatively still when in the detection state. At the same time, the rotation of the driving motor 8 on the mounting plate 7 is locked, which can ensure the stability of the rotating frame 2 while maintaining a stationary state. Subsequently, the lock head is matched with the second detection groove 5 through the detection frame 3 and the rotating frame 2. During the detection process, the lock head firstly contacts with the rolling contact of multiple contact rollers 10, wherein the contact roller 10 is flush with the upper end surface of the connecting groove 9 to avoid interference with the movement of the search lock head. When the lock head contacts the driving roller 12, the rotation of the driving roller 12 in the driving groove 11 is driven by the traction motor 13, and the rolling contact between the driving roller 12 and the lock head drives The lock moves in the second detection groove 5 to complete the detection of one surface of the lock. When the detection surface needs to be converted, the rotation of the driving motor 8 on the mounting plate 7 drives the rotating shaft to rotate 90°, and drives the detection frame 3 and the rotating frame 2 to rotate 90° on the base 1. At this time, under the connection of the limit frame 14, the limit shaft 16 is rollingly connected in the limit groove 15. When the limit shaft 16 reaches the other end of the limit groove 15, the first detection groove 4 is in the detection position. Through the cooperation between the lock and the first detection groove 4 and the movement process of the above-mentioned lock, the detection process of both sides of the lock can be completed. During this process, the connecting frame 6 and the base 1 maintain support for the detection frame 3 to ensure stability during the detection process.

[0024] Finally, the most important contribution of the present invention over the prior art is that, by rotating the rotating frame 2 on the base 1 and cooperating with the first detection slot 4 and the second detection slot 5 on the detection frame 3, it is possible to achieve convenient replacement when detecting different surfaces of the lock, and conveniently adjust the detection slot during the lock detection process. At the same time, in conjunction with the rolling contact and contact of the driving roller 12 and the contact roller 10, the stability of the movement of the lock during the detection process can be maintained.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
