[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1-2As shown, this utility model provides a synchronous linkage gas spring, including a base 1. Four gas spring bodies 4 are fixedly connected to the upper side of the base 1. Each of the four gas spring bodies 4 is provided with a mounting mechanism 3 at its upper end. A holding plate 2 is fixedly connected to the upper side of the mounting mechanism 3. A bidirectional synchronous motor 5 is fixedly connected to the middle of the upper side of the base 1. Threaded rods 6 are fixedly connected to both output ends of the bidirectional synchronous motor 5. The outer walls of the two threaded rods 6 are threaded with opposite thread directions. A stop block 7 is fixedly connected to the end of the threaded rod 6 away from the bidirectional synchronous motor 5. Two limiting blocks 8 are fixedly connected to the front and rear ends of the lower side of the base 1. A track 9 is slidably connected to the lower side of the base 1. Two limiting grooves 10 are opened on the upper side of the track 9. The outer walls of the limiting blocks 8... The track 9 is slidably connected to the limiting groove 10. The outer wall of the track 9 is slidably connected to the moving block 11. The left and right sides of the moving block 11 are fixedly connected to the connecting plate 12. The end of the connecting plate 12 away from the moving block 11 is fixedly connected to the support plate 13. The outer wall of the threaded rod 6 is threadedly connected to the support plate 13. A sliding groove is opened in the middle of the upper side of the base 1. The outer wall of the support plate 13 is slidably connected to the sliding groove. By starting the bidirectional synchronous motor 5, the bidirectional synchronous motor 5 can drive the threaded rods 6 at both ends to rotate. Since the thread directions of the threaded rods 6 at both ends are opposite, when the threaded rods 6 are rotated at the same time, the support plate 13 can be driven to move in opposite directions or in opposite directions, thereby driving the connecting plate 12 to move. The connecting plate 12 can drive the connecting block 16 to move.

[0024] like Figure 3-5As shown, this utility model provides a technical solution: Preferably, movable slots 20 are provided on both the left and right sides of the movable block 11, and a slot is provided on the upper side of the movable block 11. Curved grooves 19 are provided on both the left and right sides of the inner surface of the slot. A plurality of locking blocks 17 are fixedly connected to both the left and right sides of the inner surface of the track 9. A connecting block 16 is locked to the outer wall of the locking block 17. The lower end of the connecting block 16 is fixedly connected to the connecting plate 12. A partition plate 18 is fixedly connected to the lower side of the inner wall of the movable block 11. A first spring 15 is fixedly connected to the side of the connecting plate 12 near the partition plate 18. The other end of the first spring 15 is fixedly connected to the partition plate 18. The partition plate 18 has movable slots 20 on both the left and right sides of the track 9. A guide post 14 is fixedly connected, and the outer wall of the guide post 14 away from the partition plate 18 is slidably connected to the connecting plate 12. The mounting mechanism 3 includes a push block 31, and a movable sleeve 32 is fixedly connected to the side of the push block 31 near the gas spring body 4. A connecting post 36 is slidably connected to the inner wall of the movable sleeve 32, and a second spring 35 is sleeved on the outer wall of the connecting post 36. An insert post 33 is fixedly connected to the upper end of the gas spring body 4. A round block 37 is slidably connected to the outer wall of the movable sleeve 32, and a buckle 34 is fixedly connected to the side of the outer wall of the movable sleeve 32 near the insert post 33. One end of the second spring 35 is fixedly connected to the round block 37, and the other end of the second spring 35 is fixedly connected to the movable sleeve 32. The outer wall of the insertion post 33 is provided with a groove, and the outer wall of the buckle 34 is movably connected to the groove. When the connecting block 16 moves, it can compress the first spring 15, and the connecting plate 12 can move stably on the guide post 14. The connecting block 16, in conjunction with the snap-fit ​​block 17, can fix or loosen the moving block 11. When the connecting block 16 and the snap-fit ​​block 17 are snapped together, the moving block 11 can be fixed. When the connecting block 16 and the snap-fit ​​block 17 are separated, the moving block 11 can be moved. The movement of the moving block 11 can drive the base 1 to move, thus driving the limit block 8 to move. The limit block 8 and the limit groove 10 are mutually matched. When the base 1 moves stably, the mounting mechanism 3 is removed when the holding plate 2 needs to be disassembled. Pressing the button 31 first causes the moving sleeve 32 to move, which in turn causes the second spring 35 to retract and the buckle 34 to leave the groove on the insertion post 33. This allows the insertion post 33 to be moved and the mounting mechanism 3 to be removed. Similarly, when installing the holding plate 2, pressing the button 31 first causes the buckle 34 to move, and then the insertion post 33 is inserted into the round block 37. Releasing the button 31 causes the second spring 35 to reset the moving sleeve 32, which in turn causes the buckle 34 to engage with the groove on the insertion post 33, thus limiting and fixing the insertion post 33.

[0025] The working principle of this synchronous linkage gas spring will be explained in detail below.

[0026] like Figure 1-5As shown, the item is placed on the holding plate 2, and the bidirectional synchronous motor 5 is started. The bidirectional synchronous motor 5 can drive the threaded rods 6 at both ends to rotate. Since the thread directions of the threaded rods 6 at both ends are opposite, when the threaded rods 6 are rotated at the same time, the support plate 13 can be driven to move in opposite directions, thereby driving the connecting plate 12 to move. The connecting plate 12 can drive the connecting block 16 to move. When the connecting block 16 moves, it can compress the first spring 15, and the connecting plate 12 can move stably on the guide post 14. The connecting block 16, in conjunction with the locking block 17, can fix or loosen the moving block 11. When the connecting block 16 and the locking block 17 are locked together, the moving block 11 can be fixed. When the connecting block 16 and the locking block 17 are separated, the moving block 11 can be fixed. When the base 1 moves, the moving block 11 moves, which in turn moves the limiting block 8. The cooperation between the limiting block 8 and the limiting groove 10 allows the base 1 to move stably. When the holding plate 2 needs to be removed, press the button 31 first. The button 31 moves the moving sleeve 32, which in turn moves the second spring 35 and causes the buckle 34 to leave the groove on the insertion post 33. This allows the insertion post 33 to be moved and the installation mechanism 3 to be removed. Similarly, when installing the holding plate 2, press the button 31 first. The button 31 moves the buckle 34, and then the insertion post 33 is inserted into the round block 37. Release the button 31, and the second spring 35 will cause the moving sleeve 32 to reset, thereby causing the buckle 34 to engage with the groove on the insertion post 33 and fix the insertion post 33.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
