DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following is a further detailed description of the present utility model with reference to the Figures 1-4 accompanying drawings.

[0028] An embodiment of the utility model discloses an anti-vibration structure for a U-shaped tube. Refer to Figures 1-4 , an anti-vibration structure for a U-shaped tube, includes a support base 1 and a U-shaped tube 2 arranged at the top end of the support base 1. Placing plates 3 are provided at the bottom ends of both straight rod parts of the U-shaped tube 2. Two buffer rods 4 are hinged at the bottom ends of the two placing plates 3. Sliders 5 are hinged at the bottom ends of the four buffer rods 4. Two movable seats 6 are slidably connected to the top end of the support base 1. Sliding grooves 7 for the sliders 5 to slide are provided at the top ends of the two movable seats 6. The sliding grooves 7 are connected to the sliders 5 through buffer components 8.

[0029] In this embodiment, the U-shaped tube 2 is placed on the placing plate 3. When the U-shaped tube 2 vibrates, the U-shaped tube 2 drives the vibration of the placing plate 3, the placing plate 3 drives the vibration of the buffer rods 4, and the buffer rods 4 drive the movement of the sliders 5 during vibration. The sliders 5 squeeze the buffer components 8 during movement. Thus, with the cooperation of the buffer components 8, the U-shaped tube 2 can be buffered and protected, the vibration damage of the U-shaped tube 2 can be reduced, and the service life of the U-shaped tube 2 is improved.

[0030] The utility model is further improved on the basis of the patent number CN205793414U. Structures such as the support base 1 and the movable seat 6 in the utility model have been specifically disclosed in this patent. Therefore, the utility model does not specifically describe the above structures.

[0031] In a further embodiment, as Figure 2 shown, the buffer component 8 includes a damper 81 fixedly arranged between the slider 5 and the sliding groove 7. A first spring 82 is sleeved on the outer wall of the damper 81. A support component 9 for supporting the placing plate 3 is provided at the top end of the movable seat 6. The support component 9 includes a first support plate 91 fixedly arranged at the top end of the movable seat 6. A second support plate 92 fixed to the placing plate 3 is inserted and connected to the top end of the first support plate 91.

[0032] When the U-shaped tube 2 vibrates during use, the U-shaped tube 2 drives the vibration of the placing plate 3. At the same time, with the cooperation of the first support plate 91 and the second support plate 92, the placing plate 3 is supported to keep the movement of the placing plate 3 stable. The placing plate 3 drives the vibration of the buffer rods 4, and the buffer rods 4 drive the movement of the sliders 5. The sliders 5 squeeze the damper 81 and the first spring 82 during movement. With the cooperation of the damper 81 and the first spring 82, the U-shaped tube 2 can be buffered and protected, the vibration damage of the U-shaped tube 2 can be reduced, and the service life of the U-shaped tube 2 is improved.

[0033] In a further better embodiment of the utility model, as Figure 3As shown in the figure, placing grooves 10 for placing the straight rod portions of the U-shaped tube 2 are formed at the tops of both placing plates 3. Pressing plates 11 for fixing the U-shaped tube 2 are hinged to both sides at the tops of the two placing plates 3. The two pressing plates 11 on the same placing plate 3 are fixedly connected by a connecting plate 12. Fixing assemblies 13 for fixing the connecting plate 12 are provided on one side of each of the two placing plates 3.

[0034] Place the two straight rod portions of the U-shaped tube 2 in the two placing grooves 10 respectively. Then manually rotate the connecting plate 12. The connecting plate 12 drives the synchronous movement of the pressing plates 11 to cover the pressing plates 11 on the straight rod portions of the U-shaped tube 2. Then, with the cooperation of the fixing assembly 13, the connecting plate 12 is fixed, and thus the pressing plates 11 can be fixed, so as to fix the U-shaped tube 2, which facilitates the quick installation and fixing of the U-shaped tube 2 and improves the fixing efficiency of the U-shaped tube 2.

[0035] In a further embodiment, as Figures 3-4 shown, the fixing assembly 13 includes an L-shaped plate 131 fixedly arranged on one side of the connecting plate 12. A fixing groove 132 is formed on one side of the vertical section of the L-shaped plate 131. A side plate 133 is fixedly arranged on one side of the placing plate 3. A fixing plate 134 adapted to the fixing groove 132 is inserted through the side plate 133. A driving assembly 14 for driving the movement of the fixing plate 134 is provided on one side of the side plate 133. The driving assembly 14 includes a moving plate 141 fixedly arranged at one end of the fixing plate 134. The moving plate 141 is fixedly connected to the side plate 133 by a second spring 142. A handle 143 is fixedly arranged on the side of the moving plate 141 away from the fixing plate 134.

[0036] After the U-shaped tube 2 is placed in the placing groove 10, cover the pressing plate 11 on the U-shaped tube 2. At this time, the L-shaped plate 131 is located on the side of the placing plate 3. Then, under the elastic action of the second spring 142, drive the movement of the moving plate 141. The moving plate 141 drives the movement of the fixing plate 134 to insert the fixing plate 134 into the fixing groove 132, and thus the L-shaped plate 131 can be fixed, and then the connecting plate 12 can be fixed, so as to press and fix the U-shaped tube 2 through the pressing plate 11, which is convenient for the quick fixing of the U-shaped tube 2. When the U-shaped tube 2 needs to be disassembled, manually pull the handle 143. The handle 143 drives the movement of the moving plate 141. The moving plate 141 drives the fixing plate 134 to move away from the fixing groove 132, so that the fixing plate 134 is separated from the fixing groove 132. Then manually rotate the connecting plate 12. The connecting plate 12 drives the pressing plate 11 to move away from the U-shaped tube 2, and thus the U-shaped tube 2 can be taken out of the placing groove 10.

[0037] The implementation principle of a shock-proof structure for a U-shaped tube in an embodiment of the present utility model is as follows: First, the two straight rod portions of the U-shaped tube 2 are respectively placed in the two placement grooves 10. Then, manually rotate the connecting plate 12, and the connecting plate 12 drives the synchronous movement of the corresponding pressing plate 11, so that the pressing plate 11 presses and covers the U-shaped tube 2. During the rotation of the connecting plate 12, the L-shaped plate 131 is driven to rotate to the side position of the placement plate 3. Before the L-shaped plate 131 rotates, first manually pull the handle 143, and the handle 143 drives the movement of the moving plate 141. The moving plate 141 drives the fixed plate 134 to move to the right. At the same time, the moving plate 141 stretches the second spring 142 during movement. When the L-shaped plate 131 rotates to the side of the placement plate 3, release the handle 143. At this time, under the elastic action of the second spring 142, the moving plate 141 is driven to reset, and the moving plate 141 drives the reverse movement of the fixed plate 134, so that the fixed plate 134 is inserted into the fixing groove 132, and the L-shaped plate 131 can be fixed, thereby fixing the pressing plate 11, and the U-shaped tube 2 can be fixed, which is convenient for the quick fixing of the U-shaped tube 2 and improves the fixing efficiency of the U-shaped tube 2. When the U-shaped tube 2 vibrates during use, the U-shaped tube 2 drives the vibration of the placement plate 3, the placement plate 3 drives the vibration of the buffer rod 4, and the buffer rod 4 drives the movement of the slider 5. During the movement of the slider 5, the damper 81 and the first spring 82 are squeezed. With the cooperation of the damper 81 and the first spring 82, the U-shaped tube 2 can be buffered and protected, reducing the vibration damage of the U-shaped tube 2 and improving the service life of the U-shaped tube 2.

[0038] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
