[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0024] The present utility model provides as Figures 1-4The shown car seat handling fixture device includes an outer frame 1. A cavity 2 is provided inside the outer frame 1. A motor 3 is fixedly connected to the side wall of the outer frame 1, and the output shaft of the motor 3 is drivingly connected to a driving shaft 4. The end of the driving shaft 4 is rotatably connected to the inner wall of the cavity 2 through a bearing. A clamping plate 6 is threadedly connected to the outer ring of the driving shaft 4, and the clamping plate 6 can perform clamping operations on both sides of the car seat main body 14. A notch 8 is provided inside the side plate of the outer frame 1. The notch 8 communicates with the cavity 2. A linkage shaft 9 is rotatably connected to the inner wall of the notch 8 through a bearing, and the linkage shaft 9 is drivingly connected to the driving shaft 4 through a chain 10. A movable plate 11 is fixedly sleeved on the outer ring of the linkage shaft 9, and a soft pad 12 is fixedly connected to the outer wall of the movable plate 11. A rear abutting plate 15 is fixedly connected to the bottom of the outer frame 1, and the rear abutting plate 15 can be attached to the back of the car seat main body 14.

[0025] Both the bottom of the cavity 2 and the notch 8 are open, so as to facilitate the movement of the clamping plate 6 and the movable plate 11.

[0026] Two groups of threads 5 are provided on the outer ring of the driving shaft 4, and the two groups of threads 5 are symmetrically arranged with reference to the central axis of the driving shaft 4. Moreover, the outer rings of the two groups of threads 5 are both threadedly connected to the clamping plate 6. In this way, when the driving shaft 4 rotates, the two clamping plates 6 can move towards each other or separate from each other synchronously.

[0027] The clamping plate 6 is in an "L" shape, and the two clamping plates 6 are symmetrically arranged. Moreover, a cross plate is connected to the side wall of the bottom of each clamping plate 6 close to the side wall of the car seat main body 14. An arc surface 7 is provided at the end of the cross plate, which is convenient for the movement of the two clamping plates 6 to clamp and carry the car seat main body 14. The cross plate can support the bottom of the car seat main body 14 to prevent the car seat main body 14 from slipping;

[0028] The upper end side wall of the clamping plate 6 is attached to and slidably connected to the inner wall of the cavity 2 to ensure the stability of the movement of the clamping plate 6.

[0029] Sprockets are fixedly sleeved at the middle positions of the rod bodies of the linkage shaft 9 and the driving shaft 4. Moreover, the diameter of the sprocket sleeved on the outer ring of the linkage shaft 9 is larger than the diameter of the sprocket sleeved on the outer ring of the driving shaft 4. And the two sprockets are drivingly connected through a chain 10. In this way, when the driving shaft 4 rotates, it drives the linkage shaft 9 to rotate in the same direction synchronously, but it can ensure that the rotational speeds of the driving shaft 4 and the linkage shaft 9 are different, which is convenient for the two clamping plates 6 and the movable plate 11 to contact the car seat main body 14 simultaneously and clamp the car seat main body 14 during movement.

[0030] A notch 13 is provided in the plate body of the movable plate 11 located inside the notch 8, and the sprocket sleeved on the outer ring of the linkage shaft 9 and a part of the chain 10 in driving connection with this sprocket are located inside the notch 13, so that the movable plate 11 does not affect the transmission of the chain 10.

[0031] Working principle: When using the automobile seat transport clamp device, first start the motor 3 to drive the rotation of the drive shaft 4 connected to the output shaft of the motor 3. When the chain 10 is connected, the linkage shaft 9 rotates synchronously in the same direction. At this time, the movable plate 11 fixedly connected to the outer ring of the linkage shaft 9 rotates toward the direction of the car seat body 14. The two clamping plates 6 threadedly connected by two threads 5 symmetrically arranged on the outer ring of the drive shaft 4 move towards each other at this time, so that the two clamping plates 6 clamp the two sides of the car seat body 14. At this time, the movable plate 11 moves synchronously and cooperates with the rear abutment plate 15 to clamp the front and rear sides of the car seat body 14. Such a four-way clamping operation makes the car seat body 14 more stable during the clamping and transporting process, thereby facilitating subsequent transport. Similarly, when the motor 3 drives the drive shaft 4 to rotate in the opposite direction, the two clamping plates 6 and the movable plate 11 move in a direction away from the car seat body 14, thereby canceling the clamping of the car seat body 14.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
