Description

Technical Field

[0001] This utility model relates to the technical field of graphite tube fixing devices, specifically a graphite tube fixing device with shock resistance and anti-slip properties. Background Technology

[0002] Graphite tubes are tubular components made of high-purity graphite material. They possess characteristics such as high temperature resistance, excellent thermal and electrical conductivity, and strong chemical stability, and are widely used in industries such as semiconductors, photovoltaics, and metallurgy. When the surface of the graphite tube is not coated, its porous structure can also be used as a gas diffusion electrode or filter material. Due to the smooth texture of the graphite tube, a graphite tube fixing device is required during installation. Existing graphite tube fixing devices consist of two symmetrically distributed arc-shaped fixing plates and a support base. The two fixing plates are hinged together, and fixing bolts are provided at both ends of the right side of the two fixing plates, allowing for tightening and loosening to secure them. The traditional graphite tube fixing device uses an arc-shaped fixing plate to press against the outer surface of the graphite tube to achieve fixation. However, the fixing bolts on both sides cannot be tightened simultaneously, resulting in uneven force on the graphite tube. Furthermore, the fixing device lacks an anti-slip structure. The outer surface of the graphite tube is smooth, and when vibration occurs, the unevenly stressed graphite tube will deflect and shift inside the arc-shaped fixing plate. Therefore, we propose a graphite tube fixing device with shock resistance and anti-slip properties. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a graphite tube fixing device with shock resistance and anti-slip properties. It is equipped with an anti-slip fixing mechanism, which fixes two fixing plates by squeezing the wedge block through the wedge groove. It can simultaneously limit the front and rear sides of the fixing plate. With the squeezing of two anti-slip pads, the adsorption of anti-slip rubber rings, and the energy absorption of two energy-absorbing rubber pads, the graphite tube can be prevented from deflecting and displacing, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a graphite tube fixing device with shock resistance and anti-slip properties, comprising a base and an anti-slip fixing mechanism;

[0005] Base: It has two fixing plates at the top, which are symmetrically distributed vertically and are hinged together by a hinge on the left side;

[0006] Anti-slip fixing mechanism: It includes a bidirectional lead screw, a limiting block, a wedge groove, a wedge block, and an anti-slip component. The bidirectional lead screw is rotatably connected to the right side of the lower fixing plate. The limiting blocks are slidably connected to the front and rear ends of the right side of the lower fixing plate. The inner center of each limiting block is threaded to the outer surface of the bidirectional lead screw. The wedge grooves are all opened on the side of the limiting block away from the middle of the bidirectional lead screw. The wedge blocks are respectively set at the edges of the front and rear ends of the right side of the fixing plate. The outer surface of each wedge block is fitted with the inner wall of the vertically adjacent wedge groove to provide a basis for the limiting work of the fixing plate. The anti-slip component is set inside the fixing plate and has an anti-slip fixing mechanism. The two fixing plates are fixed by pressing the wedge blocks with the wedge grooves. It can simultaneously limit the front and rear sides of the fixing plate. With the compression of the two anti-slip pads, the adsorption of the anti-slip rubber rings, and the energy absorption of the two energy-absorbing rubber pads, the graphite tube deflection and displacement can be avoided.

[0007] Furthermore, the anti-slip fixing mechanism also includes positioning posts. Each wedge block has a positioning hole in the center, and the positioning posts are inserted into the positioning holes to provide a positioning effect for the limiting operation of the fixing plate.

[0008] Furthermore, the anti-slip fixing mechanism also includes an adjusting nut, which is located in the middle of the outer surface of the bidirectional lead screw, providing a driving effect for the limiting operation of the fixing plate.

[0009] Furthermore, the anti-slip component includes an arc-shaped fixing plate, an anti-slip pad one, and an anti-slip pad two. The arc-shaped fixing plate is respectively disposed at the front and rear edges of the inner wall of the fixing plate. The anti-slip pad one is respectively disposed on the front and rear sides of the inner wall of the fixing plate. The outer surface of the anti-slip pad one is provided with evenly distributed horizontal stripes. The anti-slip pad two is disposed in the middle of the inner wall of the fixing plate. The outer surface of the anti-slip pad two is provided with evenly distributed vertical stripes, which can form a preliminary anti-slip effect on the graphite tube.

[0010] Furthermore, the anti-slip component also includes an anti-slip rubber ring, an air extraction cylinder, and a sealing head. The anti-slip rubber ring is located in the middle of the whole formed by the two fixed plates. The air extraction cylinder is located in the middle of the upper part of the upper fixed plate. The lower end of the air extraction cylinder is fixedly connected to the upper end of the anti-slip rubber ring. The sealing head is slidably connected to the inside of the air extraction cylinder. It can quickly adsorb and release the graphite tube by sucking air, which further improves the anti-slip effect of the graphite tube.

[0011] Furthermore, the anti-slip component also includes a lead screw and a knob. The lead screw is rotatably connected to the upper center of the upper fixed plate, and the lower end of the outer surface of the lead screw is threaded to the middle of the inner surface of the sealing head. The knob is located at the upper end of the lead screw to provide a driving effect for the anti-slip rubber ring to adsorb and release the graphite tube.

[0012] Furthermore, it also includes a connecting plate, an energy-absorbing pad one, and an energy-absorbing pad two. The connecting plate is slidably connected to the inside of the base in the middle. The lower end of the fixed plate below is fixedly connected to the upper end of the connecting plate. The energy-absorbing pad one is set in the middle of the bottom wall of the base. The lower end of the connecting plate is fixedly connected to the upper end of the energy-absorbing pad one. The energy-absorbing pad two is respectively set on the left and right sides inside the base. The side of the connecting plate away from the middle of the base is fixedly connected to the side of the vertically adjacent energy-absorbing pad two near the middle of the base. The energy absorption of the energy-absorbing pad one and the energy-absorbing pad two can reduce the impact of vibration on the graphite tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This graphite tube fixing device with shock resistance and anti-slip properties has the following advantages:

[0014] 1. The rotation of the bidirectional lead screw can drive the two limiting blocks to move synchronously. The wedge groove squeezes the wedge blocks to form a limiting effect on the front and back sides of the two fixed plates at the same time, avoiding uneven force on the graphite tube and initially improving the anti-slip performance of the graphite tube.

[0015] 2. Through the compression of two anti-slip pads and the negative pressure adsorption of the anti-slip rubber ring, the graphite tube can be fixed without deflection or displacement. Combined with the energy absorption of two energy-absorbing rubber pads, the amplitude of vibration can be absorbed and dispersed, reducing the impact of vibration on the graphite tube and further improving the anti-slip and shock-resistant performance of the graphite tube.

The side of the connecting plate 4 away from the middle of the base 1 is fixedly connected to the side of the vertically adjacent energy-absorbing pad 2 6 near the middle of the base 1. The energy-absorbing pad 1 5 and the energy-absorbing pad 2 6 can be made of dense polyurethane material. The energy absorption of the energy-absorbing pad 1 5 and the energy-absorbing pad 2 6 can reduce the impact of vibration on the graphite tube.

[0026] Anti-slip fixing mechanism 3: It includes a bidirectional lead screw 31, a limiting block 32, a wedge groove 33, a wedge block 34, and an anti-slip component 37. The bidirectional lead screw 31 is rotatably connected to the right side of the lower fixing plate 2. The middle of the right side of the lower fixing plate 2 is provided with a mounting protrusion. The outer surface of the bidirectional lead screw 31 is rotatably connected to the inner wall of the mounting protrusion. The limiting block 32 is slidably connected to the front and rear ends of the right side of the lower fixing plate 2. The front and rear ends of the right side of the lower fixing plate 2 are provided with dovetail grooves. The left end of the limiting block 32 is provided with a dovetail protrusion. The outer surface of the dovetail protrusion is slidably connected to the inner wall of the vertically adjacent dovetail groove. The middle of the inside of the limiting block 32 is threadedly connected to the outer surface of the bidirectional lead screw 31. A corrugated pipe is provided between the mounting protrusion and the vertically adjacent limiting block 32. The bellows are all sleeved on the outer surface of the bidirectional lead screw 31. The bellows will contract and expand as the limiting block 32 moves, which can protect the bidirectional lead screw 31 from the influence of the external environment. The wedge grooves 33 are all opened on the side of the limiting block 32 away from the middle of the bidirectional lead screw 31. The wedge blocks 34 are respectively set at the front and rear edges of the right side of the fixing plate 2. The outer surface of the wedge blocks 34 is fitted with the inner wall of the vertically adjacent wedge groove 33. When the wedge groove 33 moves outward, the two wedge blocks 34 are squeezed inward, providing a basis for the limiting work of the fixing plate 2. The anti-slip fixing mechanism 3 also includes positioning pins 35. The wedge blocks 34 are all provided with positioning holes in the middle of their interiors. The positioning pins 35 are all inserted into the positioning holes. The positioning hole provides a positioning effect for the limiting operation of the fixing plate 2. The anti-slip fixing mechanism 3 also includes an adjusting nut 36, which is located in the middle of the outer surface of the double-acting screw 31 and provides a driving effect for the limiting operation of the fixing plate 2. The anti-slip component 37 is located inside the fixing plate 2 and includes an arc-shaped fixing piece 371, an anti-slip pad 372, and an anti-slip pad 373. The arc-shaped fixing piece 371 is located at the front and rear edges of the inner wall of the fixing plate 2. The anti-slip pad 372 is located on the front and rear sides of the inner wall of the fixing plate 2. The outer surface of the anti-slip pad 372 is provided with evenly distributed horizontal stripes. The anti-slip pad 373 is located in the middle of the inner wall of the fixing plate 2. The outer surface of the anti-slip pad 373 is provided with evenly distributed vertical stripes. This provides a preliminary anti-slip effect for the graphite tube. The anti-slip component 37 also includes an anti-slip rubber ring 374, an air extraction cylinder 375, and a sealing head 376. The anti-slip rubber ring 374 is positioned in the middle of the whole formed by the two fixed plates 2. The anti-slip rubber ring 374, anti-slip pad one 372, and anti-slip pad two 373 can all be made of PEEK material. The air extraction cylinder 375 is positioned in the middle of the upper part of the upper fixed plate 2. The lower end of the air extraction cylinder 375 is fixedly connected to the upper end of the anti-slip rubber ring 374. The sealing head 376 is slidably connected to the inside of the air extraction cylinder 375. The outer surface of the sealing head 376 is covered with sealing rubber rings, which can quickly adsorb and release the graphite tube by suction, further improving the anti-slip effect of the graphite tube. The anti-slip component 37 also includes a lead screw 377 and a knob 378.The lead screw 377 is rotatably connected to the upper center of the upper fixed plate 2. The lower end of the outer surface of the lead screw 377 is threadedly connected to the inner center of the sealing head 376. A knob 378 is located at the upper end of the lead screw 377. Marks are provided on the surface of the knob 378 and the upper end of the upper fixed plate 2 for easy observation of the knob 378's deflection angle. This provides a driving effect for the anti-slip rubber ring 374 to adhere to and release the graphite tube. An anti-slip fixing mechanism 3 is provided, which uses a wedge groove 33 to press a wedge block 34 to fix the two fixed plates 2. This simultaneously limits the movement of the front and rear sides of the fixed plates 2. Combined with the pressing of the two anti-slip pads, the adsorption of the anti-slip rubber ring 374, and the energy absorption of the two energy-absorbing pads, it prevents the graphite tube from deflecting or shifting.

[0027] The working principle of the anti-vibration and anti-slip graphite tube fixing device provided by this utility model is as follows: When fixing the graphite tube, the upper fixing plate 2 is opened to the left, and the leftmost side of the anti-slip rubber ring 374 will deform. Then, the graphite tube is placed inside the lower fixing plate 2, and the upper fixing plate 2 is closed. The anti-slip rubber ring 374 returns to its original shape. At this time, the inner walls of the arc-shaped fixing piece 371, the first anti-slip pad 372, the second anti-slip pad 373, and the anti-slip rubber ring 374 are all in contact with the outer surface of the graphite tube. The inner walls of the first anti-slip pad 372, the second anti-slip pad 373, and the anti-slip rubber ring 374 are all deformed and tightly in contact with the outer surface of the graphite tube. The arc-shaped fixing piece 371 is made of graphite... The graphite tube provides a limiting effect. The horizontal stripes on the anti-slip pad 372 prevent the graphite tube from deflecting, and the vertical stripes on the anti-slip pad 373 prevent the graphite tube from shifting back and forth. Then, align the positioning hole on the upper fixing plate 2 with the positioning hole on the lower fixing plate 2, insert the positioning pin 35, and manually turn the adjusting nut 36 to drive the bidirectional lead screw 31 to rotate. As the bidirectional lead screw 31 rotates, the two limiting blocks 32 move simultaneously away from the middle of the bidirectional lead screw 31. As the limiting blocks 32 move, the wedge groove 33 slowly contacts the outer surface of the corresponding wedge block 34. At this time, the resistance of the adjusting nut 36 increases. Use an external wrench to turn the adjusting nut 36. 6. As the adjusting nut 36 rotates, the wedge groove 33 presses against the corresponding wedge block 34, causing the upper and lower wedge blocks 34 to move inward simultaneously. The upper and lower fixing plates 2 also fit tightly together, fixing them in place. The inner walls of the anti-slip pad 1 372, anti-slip pad 2 373, and anti-slip rubber ring 374 further deform and fit more tightly against the outer surface of the graphite tube. At this point, rotating the knob 378 drives the lead screw 377 to rotate, causing the sealing head 376 to move upward. As the sealing head 376 moves upward, observe the markings on the surface of the knob 378 and above the fixing plate 2. After the knob 378 rotates one full turn, the sealing head 376 moves into place, and the inside of the anti-slip rubber ring 374... The air remaining between the graphite tube and the anti-slip rubber ring 374 is drawn into the vacuum cylinder 375, creating a negative pressure effect between the anti-slip rubber ring 374 and the graphite tube. The anti-slip rubber ring 374 tightly adheres to the graphite tube, further preventing the graphite tube from loosening. When vibration occurs, the amplitude is transmitted to the connecting plate 4 through the base 1. The energy-absorbing rubber pad 5 and the energy-absorbing rubber pad 6 rely on their own elastic deformation to create a damping effect. The energy is absorbed and dispersed through the curled structure of the rubber molecules, allowing the rubber molecules to consume energy through dynamic equilibrium when subjected to force. This absorbs and disperses the amplitude generated by the vibration, reduces the impact of the amplitude on the graphite tube, and achieves the anti-vibration effect of the fixing device.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
