[0025] Please see Figure 1-4 This utility model provides a technical solution: a locking and unlocking device for space-constrained applications, comprising a fixed support assembly 1, a sliding support assembly 2, a cylinder 3, and a locking and unlocking mechanism 4.
[0026] The fixed support assembly 1 is disposed on one side of the conveyor line. The fixed support assembly 1 includes a first long column 11, a first short column 12, a connecting rod 13, a first support rod 14, a slide rail 15, a first mounting plate 16, and a fixing plate 17.

[0028] The sliding bracket assembly 2 includes a second short column 21, a second long column 22, a connecting pipe 23, a second support rod 24, a slider 25, a second mounting plate 26, and a connecting block 27;
[0029] There are two of each of the second long column 22 and the second short column 21. The two second long columns 22 and the two short columns 21 are distributed at four corners. The two second long columns 22, the two second short columns 21, and the two second long columns 22 and the two short columns 21 are all connected by connecting pipes 23. The lower ends of the second long columns 22 and the second short columns 21 on the same side are inclinedly provided with second support rods 24. The second support rods 24 are parallel to the first support rods 14. The lower end of the second support rods 24 is provided with sliders 25, which are slidably connected to slide rails 15. The connecting pipes 23 between the two second long columns 22 are provided with second mounting plates 26. The lower end of the connecting pipes 23 between the two first short columns 21 is provided with connecting blocks 27. The telescopic end of the cylinder 3 is connected to the connecting blocks 27. The telescopic movement of the cylinder 3 pushes the sliding bracket assembly 2 to move along the inclined direction of the slide rails 15.
[0030] The locking and unlocking structure 4 includes a drive motor 41, a lower housing 42, an upper housing 43, a drive sprocket 44, a driven sprocket 45, a chain 46, a disc 47, and an unlocking rod 48;
[0031] The drive motor 41 is fixed on the second mounting plate 26. The upper end of the connecting pipe 23 is fixed with the lower housing 42. The upper end of the lower housing 42 is provided with a detachable upper housing 43. The drive sprocket 44 and the driven sprocket 45 are both set in the gap between the lower housing 42 and the upper housing 43. The drive sprocket 44 is connected to the output shaft of the drive motor 41. A chain 46 is sleeved between the drive sprocket 44 and the driven sprocket 45. A disc 47 is provided at the upper end of the driven sprocket 45. The unlocking rod 48 is fixed at the upper end of the disc 47 and extends out of the upper housing 43. The drive motor 41 drives the drive sprocket 44 to rotate, and under the transmission of the chain 46, it drives the driven sprocket 45 to rotate, thereby driving the unlocking rod 48 to rotate, so as to realize the locking and unlocking function of the vehicle body on the skid.
[0032] Furthermore, to facilitate the adjustment of the overall height of the device and to ensure that the unlocking rod 48 corresponds to the locking and unlocking position of the skid, a height adjustment mechanism is also included. The height adjustment mechanism 5 includes a base plate 51, a screw 52, and a nut 53. The base plate 51 is located below the fixed plate 17, and the screw 52 is located at the upper end of the base plate 51. The screw 52 passes through the fixed plate 17, and the outer sides of the screw 52 located on the upper and lower sides of the fixed plate 17 are threaded with nuts 53. By adjusting the nuts 53, the distance between the fixed plate 17 and the base plate 51 can be adjusted, thereby adjusting the height of the entire device.
[0033] Furthermore, in order to ensure that the unlocking rod 48 moves accurately into place, a sensing plate 6 is provided on one side of the second support rod 24, and a sensing component is provided on the side of the conveyor line. When the sensing plate 6 is sensed, the cylinder 3 stops extending, thereby making the unlocking rod 48 located in the locking / unlocking position on the skid.
[0034] In use: When the skid is in place, the cylinder 3 is activated. The telescopic rod of the cylinder 3 pushes the sliding bracket assembly 2 to move upward along the fixed bracket assembly 1. The unlocking rod 48 then tilts and rises. After the sensing component senses the sensing plate 6, the cylinder 3 stops working. At this time, the unlocking rod 48 rises to the locked / unlocked position, and the drive motor 41 is activated. Under the transmission of the drive sprocket 44, chain 46 and driven sprocket 45, the disc 47 rotates, and the unlocking rod 48 rotates accordingly, realizing the locking and unlocking function.
[0035] This invention allows for the tilting and lifting of the locking and unlocking mechanism 4 in situations where workshop space is limited, preventing interference with other conveyor lines and enabling the locking and unlocking function of the skid.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by 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 present invention, the scope of which is defined by the appended claims and their equivalents.
