The first rotating shaft passes through the wrench, the vertical rod assembly, and the hook plate simultaneously. The hook plate is rotatably mounted at the middle position of the first rotating shaft. The eccentric bushing is mounted at both ends of the first rotating shaft for connection to the wrench. When the wrench rotates... The eccentric bushing rotates, and when the wrench rotates towards the upright assembly, the eccentric bushing drives the first rotating shaft to make an eccentric movement, and at the same time drives the hook plate to move towards the wrench so that the hook plate locks the locking plate.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0017] This specific embodiment provides a novel folding device that solves the technical problem that existing double-bar folding devices lack versatility.

[0018] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations represented in the embodiments below are not limited to those necessary for the solution of the invention described in the claims.

[0019] Reference Figures 1-8 This invention provides a novel folding device, comprising an elastic switch 1, a wrench 2, a transmission assembly 3, a hook plate 4, a vertical rod assembly 6, a fixing rod 7, and a first elastic assembly 5, wherein: The first end of the fixing rod 7 is provided with a locking plate 71, and the second end of the fixing rod 7 is rotatably connected to the upright assembly 6. The second end of the fixing rod 7 and the second end of the upright assembly 6 are used to install other parts. When the hook plate 4 is fastened to the locking plate 71, the fixing rod 7 is in a locked state, and the upright assembly 6 can be kept fixed for easy use. When the hook plate 4 is separated from the locking plate 71, the upright assembly 6 is in a movable state for easy storage.

[0020] To facilitate the locking of the hook plate 4 to the locking plate 71 and secure the upright assembly 6, a transmission component 3 is provided at the bottom of the upright assembly 6. The transmission component 3 drives the hook plate 4 to move and engage with the locking plate 71. The transmission component 3 includes a first rotating shaft and an eccentric bushing 32. The first rotating shaft passes through the wrench 2, the upright assembly 6, and the hook plate 4. The hook plate 4 is rotatably mounted in the middle position of the first rotating shaft. The upright assembly 6 is provided with two fifth mounting holes, which are installed at both ends of the hook plate 4. The eccentric bushing 32 is installed at both ends of the first rotating shaft and is used to connect with the wrench 2. When the wrench 2 rotates, it drives the eccentric bushing 32 to rotate. When the wrench 2 rotates towards the upright assembly 6, the eccentric bushing 32 drives the first rotating shaft to make an eccentric movement, and at the same time drives the hook plate 4 to move towards the wrench 2, so that the hook plate 4 engages with the locking plate 71, thereby ensuring the stability of the upright assembly 6.

[0021] To prevent the wrench 2 from remaining in a fixed position, the elastic switch 1 is slidably mounted on the wrench 2. The elastic switch 1 has a first protrusion 14 forming a first hook, with the side of the first protrusion 14 near the upright assembly 6 being curved to facilitate upward movement. The upright assembly 6 has a hanging hole 64 on the side near the wrench 2, and the wrench 2 has an opening. The elastic switch 1 is installed at the opening. When the elastic switch 1 is in the pressed state, the first hook disengages from the hanging hole 64. When the elastic switch 1 is in the free state, such as... Figure 7 As shown, the first hook can be engaged in the hanging hole 64. When the elastic switch 1 moves upward, i.e. in the pressing state, the first protrusion 14 can be disengaged from the hanging hole. When the elastic switch 1 is in a non-external force state, i.e. in the free state, the first protrusion 14 can be engaged in the hanging hole 64.

[0022] To enable the hook plate 4 to automatically return to its original position, a first elastic component 5 is installed on the upright assembly 6. Specifically, it includes a second screw 52 and a second spring 51. The hook plate 4 has an elongated hole. The second screw 52 passes through the elongated hole and is installed on the upright assembly 6. The second spring 51 is sleeved on the second screw 52, ​​with both ends of the second spring 51 abutting against the ends of the second screw 52 and the end face of the elongated hole, respectively, to enable automatic return to its original position. To prevent the second spring 51 from dislodging from the end face of the elongated hole, a shim is provided at the location of the elongated hole. The shim increases the contact between the second spring 51 and the elongated hole. The force-bearing area is reduced, thus reducing the pressure on the elongated hole when the second spring 51 is compressed, preventing the elongated hole from being damaged or enlarged, which would lead to spring failure. When the transmission component drives the hook plate away from the fixed rod 7, the second spring 51 is compressed and accumulates elastic force. When the hook plate 4 separates from the locking plate, the hook plate 4 returns to its original position under the action of the elastic force of the second spring 51, thereby achieving automatic return. When people install it, the elastic force of the second spring 51 is greater than the frictional force between the hook plate 4 and the locking plate, so that the hook plate 4 can be fastened to the fixed rod 7, that is, the end of the hook plate 4 abuts against the end of the locking plate.

[0023] When the upright assembly 6 is in the working state, the upright assembly 6 needs to be locked by the hook plate 4. In order to ensure that the position of the wrench 2 remains unchanged, the elastic switch 1 is installed on the wrench 2 and can be engaged in the hanging hole 64 on the upright assembly 6. This ensures that the position of the wrench 2, that is, the clamping force between the hook plate 4 and the locking plate remains unchanged. When people need to open it, adjust the elastic switch 1 so that the first protrusion disengages from the hanging hole 64, and turn the wrench 2. The wrench 2 drives the transmission component to move, so that the hook plate 4 separates from the locking plate 71. At the same time, the second spring 51 is compressed, and the upright assembly 6 is rotated to realize the folding between the fixed rod 7 and the upright assembly 6. Meanwhile, the hook plate 4 can return to its position under the action of the second spring 51, which is convenient for use when locking.

[0024] With this configuration, the hook plate 4 can be automatically returned to its original position by setting the first elastic component 5, which reduces the complexity of operation when folding and resetting. The elastic switch 1 can automatically lock, making the operation of the folding mechanism more flexible, while increasing the safety to prevent operational errors. To further optimize the design and facilitate the movement of the hook plate by the transmission assembly 3, the transmission assembly 3 also includes a folding action linkage 33 and a connecting shaft 34. The wrench 2 has side wings 23 on both sides, each with an arc-shaped hole 21 and a first mounting hole 22. An eccentric bushing 32 is installed in the arc-shaped hole 21 so that the wrench 2 rotates, causing the eccentric bushing 32 to rotate as well. The first mounting hole 22 connects to the folding action linkage 33, and the other end of the folding action linkage 33 is connected to the connecting shaft 34. The hook plate 4 has a first cavity 42, and the connecting shaft... 34 is inserted into the first cavity 42; wherein, the hook plate 4 is rotatably installed in the middle position of the first rotating shaft, and the hook plate 4 is provided with a second through hole, and the circular first rotating shaft is installed in the second through hole to facilitate the rotation of the hook plate 4; when the wrench 2 rotates, it drives the eccentric bushing 32 to rotate, and at the same time, the center of the eccentric bushing 32 approaches the fixed rod 7, and at the same time drives one end of the folding action linkage 33 connected to one end of the wrench 2 to rotate upward and the other end of the folding action linkage 33 to move downward, thereby driving the hook plate 4 to rotate, so that the hook plate 4 disengages from the locking plate 71.

[0025] To further optimize the design, in order to enable the hook plate 4 to smoothly detach from the locking plate 71, a second arc-shaped protrusion 331 is provided on the folding action linkage. A support rib 72 is provided at the end of the locking plate 71 away from the fixing rod 7. The support rib 72 corresponds to the position of the folding action linkage 33, that is, the second arc-shaped protrusion 331 is located below the support rib. The end face of the support rib 72 is provided with a first step surface 721 and a second step surface 722, and the first step surface 721 and the second step surface 722 are connected by an arc. The height of the first step surface 721 is lower than the height of the second step surface 722, so that the position of the first step surface 721 forms a recessed area. When the wrench 2 is turned, the second arc-shaped protrusion 331 transitions from the first step surface 721 to the second step surface 722, and the second arc-shaped protrusion 331 abuts against the second step surface 722, so that the locking plate 71 is separated from the hook plate 4.

[0026] To further optimize the design, in order to facilitate the fixing of the hook plate 4 to the locking plate 71, a third protrusion 41 is provided at the end of the hook plate 4 away from the pole assembly. The third protrusion 41 forms a second hook body. The end of the locking plate 71 includes a fourth protrusion 73. The second hook body contacts the side wall of the fourth protrusion 73. When the wrench 2 returns to its original position, that is, when the elastic switch 1 on the wrench 2 is engaged in the position of the hanging hole 64, the second hook body abuts against the side of the fourth protrusion 73, thereby ensuring the stability of the pole assembly 6.

[0027] Further optimization of the scheme: the elastic switch 1 includes a first button 11, a first screw 13, and a first spring 12. A fixing block is provided on the wrench 2, and a first through hole is provided on the fixing block. The first spring 12 is sleeved on the first screw 13. The first spring 12 passes through the first through hole and is installed on the first button 11, and the first screw 13 is installed on the first button 11. The two ends of the first spring 12 abut against the fixing block and the first button 11, or the two ends of the first spring 12 abut against the ends of the fixing block and the first screw 13. When people slide the first button 11 upward, the first spring 12 is compressed and accumulates elastic force. At the same time, the first protrusion 14 on the first button 11 disengages from the hanging hole 64. When people release the first button 11, the first button 11 moves downward under the action of the first spring force.

[0028] To further optimize the design, and to ensure that the first button 11 can be stably installed in the opening, the first button 11 includes a slider 111 and a support block 112 perpendicular to the length of the slider 111. A first protrusion 14 is provided at the end of the support block 112 away from the slider 111. A limiting protrusion is also provided on the support block 112. The limiting protrusion is positioned before the first protrusion 14 and the slider 111. A cavity is formed between the limiting protrusion and the slider 111 for installation in the opening. To prevent the slider 111 from disengaging from the opening when the first protrusion 14 disengages from the hanging hole 64, the height of the first protrusion 14 is less than the height of the limiting protrusion.

[0029] To further optimize the design, a third mounting hole is provided on the upright assembly to facilitate the installation of the eccentric bushing 32. The third mounting hole is circular, and the eccentric bushing 32 is installed in the third mounting hole, allowing both to rotate relative to each other while ensuring the stability of the eccentric bushing 32 and the third mounting hole. The cross-sectional shape of the eccentric bushing 32 is arc-shaped, and the arc of the arc is a superior arc, which facilitates the installation of the eccentric bushing 32 on the first rotating shaft. The center of the eccentric bushing 32 and the center of the first rotating shaft are not on the same straight line.

[0030] Further optimize the plan, such as Figure 1 The illustrated pole assembly includes a first pole 61, a first connecting seat 62, and the first connecting seat 62 is disposed between two first poles 61, as shown. Figure 6 , 7 As shown, there are two first connecting seats 62, distributed along the height direction of the first upright 61. The first connecting seat 62 located at the bottom is used to fix the first rotating shaft and the first elastic component. The second connecting seat 74 is provided on the fixed rod 7. The first connecting seat 62 located at the top and the second connecting seat 74 are connected by the second rotating shaft 65. That is, the rotation between the first connecting seat 62 and the second connecting seat 74 realizes the rotation between the fixed rod 7 and the first upright 61.
