[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] As Figures 1-6 shown, a manually operable movable traction seat includes a mounting base 1. Both the front and rear parts of the top of the mounting base 1 are fixedly connected with slot slide rails 11. The outer wall of the slot slide rail 11 is slidably connected with a sliding base 12. The top of the sliding base 12 is fixedly connected with a cover plate 13. The right part of the sliding base 12 is fixedly connected with a connecting plate 14. The front end of the cover plate 13 is fixedly connected with a limit clamping plate 15. The middle part of the cover plate 13 is fixedly connected with a fixed ring 16 by threads. The inner wall of the connecting plate 14 is slidably connected with a moving mechanism 2. The inner wall of the sliding base 12 is slidably connected with an installation mechanism 3. The moving mechanism 2 includes a traction handle 21. The outer wall of the traction handle 21 is slidably connected with the inner wall of the connecting plate 14. The installation mechanism 3 includes a pulling bar 31. The outer wall of the pulling bar 31 is slidably connected with the inner wall of the cover plate 13.
[0025] First, open the installation structure of the installation mechanism 3, and then drive the installation mechanism 3 to move through the moving mechanism 2 so that the connection part of the semi-trailer is connected to the installation mechanism 3.
[0026] As Figures 2-4 shown, a notch one 22 is provided at the rear of the traction handle 21. A first spring 23 is fixedly connected to the rear of the traction handle 21. A handle 24 is fixedly connected to the rear end of the traction handle 21. The outer wall of the handle 24 is slidably connected to the bottom of the sliding base 12. The left part of the first spring 23 is fixedly connected to the bottom of the sliding base 12. A second spring 26 is fixedly connected to the left part of the handle 24. The rear part of the second spring 26 is fixedly connected to the bottom of the sliding base 12.
[0027] By pulling the traction handle 21, the traction handle 21 slides on the inner wall of the connecting plate 14, and the notch one 22 is engaged with the connecting plate 14 to limit the traction handle 21. At the same time, the traction handle 21 drives the first spring 23 to stretch. The traction handle 21 drives the handle 24 to rotate around the first bolt 25, causing the second spring 26 to stretch.
[0028] As Figures 2-5 shown, the left part of the handle 24 is rotatably connected to a first bolt 25. The outer wall of the first bolt 25 is threadedly connected to the bottom of the sliding base 12. The rear part of the first bolt 25 is rotatably connected to a long handle 27. The rear part of the long handle 27 is rotatably connected to a second bolt 271. The front part of the first bolt 25 is rotatably connected to a short handle 28. The front part of the short handle 28 is rotatably connected to a third bolt 281. The outer walls of the second bolt 271 and the third bolt 281 are both rotatably connected to a fixed claw 29. The bottom of the fixed claw 29 is slidably connected to the inner wall of the sliding base 12. The outer wall of the fixed claw 29 is inserted into the inner wall of the slot slide rail 11.
[0029] When the handle 24 rotates, the handle 24 drives the long handle 27 to rotate, causing the long handle 27 to rotate around the second bolt 271. At the same time, the handle 24 drives the short handle 28 to rotate, causing the short handle 28 to rotate around the third bolt 281. In this way, the second bolt 271 and the third bolt 281 drive the fixed claw 29 to contract and move towards the middle, causing the fixed claw 29 to slide on the inner wall of the sliding base 12, so that the outer wall of the fixed claw 29 is no longer inserted into the inner wall of the slot slide rail 11. Then, the sliding base 12 can be pushed, and the sliding base 12 slides on the inner wall of the slot slide rail 11 to clamp the connection part of the semi-trailer near the inner walls of the fixed ring 16 and the snap ring 36, achieving the effect of quick connection.
[0030] As Figure 2 、 Figure 3 and Figure 6As shown in the figure, a notch two 32 is provided at the front part of the outer wall of the hand pull bar 31. A baffle 33 is fixedly connected to the rear part of the hand pull bar 31. A third spring 34 is fixedly connected to the rear part of the hand pull bar 31. The rear part of the third spring 34 is fixedly connected to the bottom of the sliding base 12. A limiting rod 35 is lapped at the rear part of the baffle 33. The outer wall of the limiting rod 35 is threadedly connected to the inner wall of the cover plate 13.
[0031] By pulling the hand pull bar 31, the notch two 32 is moved to the position where the limiting clamping plate 15 is located. Then, the notch two 32 is clamped on the limiting clamping plate 15, so that the hand pull bar 31 cannot move without external force. At the same time, when the hand pull bar 31 is pulled, the baffle 33 is driven to move synchronously. At the same time, the hand pull bar 31 drives the third spring 34 to stretch.
[0032] As Figure 3 、 Figure 6 As shown in the figure, a snap ring 36 is lapped at the right part of the outer wall of the baffle 33. A fixed shaft 37 is rotatably connected to the inner wall of the right part of the snap ring 36. The bottom end of the fixed shaft 37 is fixedly connected to the outer wall of the sliding base 12. The top end of the fixed shaft 37 is slidably connected to the bottom end of the fixed ring 16. A fourth spring 38 is fixedly connected to the rear part of the fixed shaft 37. The rear part of the fourth spring 38 is fixedly connected to the rear part of the sliding base 12.
[0033] When the baffle 33 gradually moves following the hand pull bar 31, the blocking effect of the baffle 33 on the snap ring 36 gradually decreases. Under the action of the elastic force of the fourth spring 38, the snap ring 36 rotates around the fixed shaft 37. When the notch two 32 is clamped with the limiting clamping plate 15, at this time, under the action of the elastic force of the fourth spring 38, the outer wall of the snap ring 36 contacts the outer wall of the limiting rod 35 to limit the snap ring 36. At this time, the opening direction of the snap ring 36 is the same as the opening direction of the fixed ring 16. Then, the connection part of the semi-trailer can be connected to the device, achieving the effect of facilitating subsequent installation.
[0034] Working principle of the utility model: When in use, when it is necessary to connect the semi-trailer with the vehicle head, first pull the manual lever 31 to move the notch two 32 to the position where the limit clamping plate 15 is located. Then, clamp the notch two 32 on the limit clamping plate 15 so that the manual lever 31 cannot move without external force. At the same time, when pulling the manual lever 31, the baffle 33 is driven to move synchronously. At the same time, the manual lever 31 drives the spring three 34 to stretch. When the baffle 33 gradually moves with the manual lever 31, the blocking effect of the baffle 33 on the snap ring 36 gradually decreases. Under the elastic force of the spring four 38, the snap ring 36 rotates around the fixed shaft 37. When the notch two 32 is clamped with the limit clamping plate 15, at this time, under the elastic force of the spring four 38, the outer wall of the snap ring 36 contacts the outer wall of the limit rod 35 to limit the snap ring 36. At this time, the opening direction of the snap ring 36 is the same as the opening direction of the fixed ring 16. Subsequently, the connection part of the semi-trailer can be connected to the device, which facilitates subsequent installation. After that, pull the traction handle 21 to make the traction handle 21 slide on the inner wall of the connecting plate 14, and clamp the notch one 22 with the connecting plate 14 to limit the traction handle 21. At the same time, the traction handle 21 drives the spring one 23 to stretch. The traction handle 21 drives the handle 24 to rotate around the bolt one 25 to stretch the spring two 26. At the same time, the handle 24 drives the long handle 27 to rotate, so that the long handle 27 rotates around the bolt two 271. And at the same time, the handle 24 drives the short handle 28 to rotate, so that the short handle 28 rotates around the bolt three 281. In this way, the bolt two 271 and the bolt three 281 drive the fixed claw 29 to contract and move towards the middle, so that the fixed claw 29 slides on the inner wall of the sliding base 12, and the outer wall of the fixed claw 29 no longer plugs into the inner wall of the slot slide rail 11. Subsequently, the sliding base 12 can be pushed to make the sliding base 12 slide on the inner wall of the slot slide rail 11, and the connection part of the semi-trailer is clamped close to the inner walls of the fixed ring 16 and the snap ring 36. Then, pull the traction handle 21 and the manual lever 31 respectively, so that the traction handle 21 no longer clamps with the connecting plate 14. Under the elastic force of the spring one 23 and the spring two 26, the fixed claw 29 is re-plugged into the slot slide rail 11. At the same time, the manual lever 31 no longer clamps with the limit clamping plate 15. Under the elastic force of the spring three 34, the manual lever 31 is reset. During the reset process, rotate the limit rod 35 to push the snap ring 36, so as to facilitate the baffle 33 to block the snap ring 36. Thus, the connection is completed, which facilitates the connection and greatly improves the use experience.
