Description

Technical Field

[0001] The utility model relates to the technical field of modified nylon cavity carriers, and specifically relates to a cavity carrier structure of modified nylon. Background Technique

[0002] Compared with other materials, plastics have the advantages of light weight, excellent chemical stability, and poor heat conduction ability. From the mechanical properties such as the hardness, tensile strength, elongation rate, and impact strength of plastics, there is a large room for use selection. However, when the existing cavity carriers are in use, due to long-term vibration and stress, they will be damaged or deformed under stress.

[0003] Currently, there is a modified nylon cavity carrier with a patent number of 202320715689.0, which includes a top plate, a bottom plate, a compression spring, a limit seat, a buffer cylinder body, a connecting rod, a moving plate, a protective seat, and a rubber membrane. The inner wall of the nylon cavity carrier body is provided with a top plate, the outer surface of the inner reinforcing body is provided with a bottom plate, the compression spring is bonded to the upper end surface of the bottom plate, the limit seat is arranged on the upper end surface of the bottom plate, the buffer cylinder body is installed on the upper end surface of the limit seat, the moving plate is movably arranged inside the buffer cylinder body, the protective seat is bonded inside the buffer cylinder body, the rubber membrane is arranged on the upper end surface of the buffer cylinder body, and the connecting rod is bonded to the upper end surface of the moving plate. This design solves the problem that the buffer method of the original modified nylon cavity carrier is prone to cause metal fatigue of the buffer support rib plate, thereby reducing the buffer effect. The utility model has a reasonable structure, is simple and convenient to install, has a good buffer effect on multi-directional vibrations, has a long service life, and a wide range of applications.

[0004] However, after the above patent is improved, there is a problem that after long-term use, the bottom plate and the buffer cylinder body are respectively subjected to the thrust of the spring and the top plate, and the low strength of the bottom plate and the buffer cylinder body will cause fatigue damage to both under stress. For this reason, we propose a cavity carrier structure of modified nylon. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a cavity carrier structure of modified nylon, which solves the problems put forward in the above background technique.

[0006] To achieve the above object, the utility model is realized by the following technical solutions: A cavity support structure of modified nylon, comprising a nylon cavity support body, an inner reinforcing body, a bottom plate and a top plate. On one side of the bottom plate and the top plate close to each other, a first fixing plate and a second fixing plate are respectively arranged. Below the upper surface of the first fixing plate and above the lower surface of the second fixing plate, a number of first fixing bolts are arranged. The number of first fixing bolts respectively penetrate through the first fixing plate and the second fixing plate and are threadedly connected thereto. The number of first fixing bolts are respectively inserted into the interior of the bottom plate and the top plate and are threadedly connected thereto. At the top of the first fixing plate, an outer cylinder and a reinforcing column are fixedly installed. At the top of the outer cylinder, a limiting plate is fixedly installed. At the bottom of the second fixing plate, a sleeve column is fixedly installed. The sleeve column is inserted into the interior of the outer cylinder and is slidably connected thereto. The reinforcing column is inserted into the interior of the sleeve column and is slidably connected thereto. The limiting plate is inserted into the interior of the sleeve column and is slidably connected thereto. At the bottom of the sleeve column and outside the reinforcing column, a compression spring is arranged. The two ends of the compression spring are respectively fixedly connected to the first fixing plate and the sleeve column.

[0007] Preferably, a sound-absorbing cotton is arranged at the bottom of the sleeve column and outside the compression spring. The two sides of the sound-absorbing cotton are respectively fixedly connected to the first fixing plate and the sleeve column. By arranging the sound-absorbing cotton, which is flexible and can be compressed, it blocks the abnormal noise emitted by the compression spring and achieves the effect of noise reduction.

[0008] Preferably, a number of second fixing bolts are arranged on one side of the bottom plate and the top plate close to each other. The number of second fixing bolts respectively penetrate through the bottom plate and the top plate and are threadedly connected thereto. The number of second fixing bolts are respectively inserted into the interior of the nylon cavity support body and the inner reinforcing body and are threadedly connected thereto. By arranging a number of second fixing bolts on one side of the bottom plate and the top plate close to each other, the device is fixedly connected to the nylon cavity support body and the inner reinforcing body through the second fixing bolts.

[0009] Preferably, a number of T-shaped limiting rods are fixedly installed at the bottom of the second fixing plate. The number of T-shaped limiting rods all penetrate through the limiting plate and are slidably connected thereto. By arranging the T-shaped limiting rods, it further prevents the sleeve column from driving the compression spring to rotate when moving longitudinally.

[0010] Preferably, support plates are arranged on both sides of the outer cylinder corresponding to each other between the bottom plate and the top plate. On the outer sides of the two support plates close to the top plate, a first auxiliary block is rotatably connected through a rotating shaft. Both first auxiliary blocks are inserted into the interior of the top plate and fixedly connected thereto. On the outer sides of the two support plates close to the bottom plate, a second auxiliary block is rotatably connected through a rotating shaft.

The two fixing rods are fixedly connected to the bottom plate. The two fixing rods respectively penetrate through the two second auxiliary blocks and are slidably connected thereto. Buffer springs are arranged on the outer sides of the two fixing rods on the sides away from each other of the two sliding grooves. Both ends of the two buffer springs are respectively fixedly connected to the bottom plate and the second auxiliary block. By rotating the two support plates synchronously and in opposite directions, the two sliding plates move away from each other, so that the two buffer springs are compressed. At the same time, the buffer springs provided achieve the effect of buffering and shock absorption in the horizontal direction of the device.

[0011] Preferably, a sliding plate is fixedly installed at the bottom of each of the two second auxiliary blocks. The sliding plate is slidably connected to the sliding groove. Wear-resistant coatings are arranged on the surfaces of the outer cylinder and the strengthening column close to each other. By arranging the sliding plate to limit the lateral movement position of the second auxiliary block, the minimum distance after compression between the bottom plate and the top plate is further limited, preventing damage to the compression spring and the buffer spring caused by excessive extrusion. And by arranging wear-resistant coatings on the surfaces of the outer cylinder and the strengthening column close to each other, the wear caused by the movement of the strengthening column and the sleeve column is reduced.

[0012] The utility model provides a cavity carrier structure of modified nylon, which has the following beneficial effects:

[0013] 1. For the cavity carrier structure of modified nylon, the sleeve column slides between the outer cylinder and the strengthening column, and the sound-absorbing cotton slides on the outer side of the strengthening column, thereby reducing the possibility of the outer cylinder and the first fixing plate being deformed and damaged under force.

[0014] 2. For the cavity carrier structure of modified nylon, the compression spring is used for buffering and shock absorption in the longitudinal direction. At the same time, by rotating the two support plates synchronously and in opposite directions, the two sliding plates move away from each other, so that the two buffer springs are compressed. At the same time, the buffer springs provided achieve the effect of buffering and shock absorption in the horizontal direction of the device, improving the practicability of the device.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a cavity carrier structure of modified nylon, including a nylon cavity carrier body 1, an inner reinforcing body 2, a bottom plate 3 and a top plate 4. On the sides of the bottom plate 3 and the top plate 4 close to each other, a first fixing plate 6 and a second fixing plate 7 are respectively arranged. Below the upper surface of the first fixing plate 6 and above the lower surface of the second fixing plate 7, a number of first fixing bolts 13 are arranged. The number of first fixing bolts 13 respectively penetrate through the first fixing plate 6 and the second fixing plate 7 and are threadedly connected therewith. The number of first fixing bolts 13 are respectively inserted into the interiors of the bottom plate 3 and the top plate 4 and are threadedly connected therewith. The top of the first fixing plate 6 is fixedly provided with an outer cylinder 5 and a reinforcing column 8. The top of the outer cylinder 5 is fixedly provided with a limiting plate 11. The bottom of the second fixing plate 7 is fixedly provided with a sleeve column 10. The sleeve column 10 is inserted into the interior of the outer cylinder 5 and is slidably connected therewith. The reinforcing column 8 is inserted into the interior of the sleeve column 10 and is slidably connected therewith. The limiting plate 11 is inserted into the interior of the sleeve column 10 and is slidably connected therewith. At the bottom of the sleeve column 10 and outside the reinforcing column 8, an extrusion spring 9 is arranged. The two ends of the extrusion spring 9 are respectively fixedly connected with the first fixing plate 6 and the sleeve column 10.

[0023] A sound-absorbing cotton 12 is provided at the bottom of the sleeve column 10 and outside the extrusion spring 9. Both sides of the sound-absorbing cotton 12 are fixedly connected to the first fixing plate 6 and the sleeve column 10 respectively. The provided sound-absorbing cotton 12 is flexible and can be compressed, and the provided sound-absorbing cotton 12 plays a role in buffering the extrusion spring 9. On the sides of the bottom plate 3 and the top plate 4 close to each other, a number of second fixing bolts 16 are provided. The number of second fixing bolts 16 respectively penetrate through the bottom plate 3 and the top plate 4 and are threadedly connected thereto. The number of second fixing bolts 16 are respectively inserted into the nylon cavity support body 1 and the inner reinforcing body 2 and are threadedly connected thereto. By providing a number of second fixing bolts 16 on the sides of the bottom plate 3 and the top plate 4 close to each other, the bottom plate 3 is connected to the inner reinforcing body 2 and the top plate 4 is connected to the nylon cavity support body 1 by the action of the number of second fixing bolts 16 provided on one side of the bottom plate 3. A number of T-shaped limiting rods 14 are fixedly installed at the bottom of the second fixing plate 7. The number of T-shaped limiting rods 14 all penetrate through the limiting plate 11 and are slidably connected thereto. By providing the T-shaped limiting rods 14, the sleeve column 10 is further prevented from driving the extrusion spring 9 to rotate when moving longitudinally, reducing the possibility of damage to the extrusion spring 9.

[0024] Support plates 20 are provided on the corresponding two sides of the outer cylinder 5 between the bottom plate 3 and the top plate 4. On the outer sides of the two support plates 20 close to the top plate 4, a first auxiliary block 17 is rotatably connected through a rotating shaft. The two first auxiliary blocks 17 are respectively inserted into the top plate 4 and fixedly connected thereto. On the outer sides of the two support plates 20 close to the bottom plate 3, a second auxiliary block 21 is rotatably connected through a rotating shaft. A sliding groove 18 matching the two second auxiliary blocks 21 is formed on the bottom plate 3. The two second auxiliary blocks 21 are respectively inserted into the two sliding grooves 18 and are slidably connected thereto. Fixing rods 19 are fixedly installed inside the two sliding grooves 18. The two fixing rods 19 are both fixedly connected to the bottom plate 3. The two fixing rods 19 respectively penetrate through the two second auxiliary blocks 21 and are slidably connected thereto. Buffer springs 23 are provided on the outer sides of the two sliding grooves 18 away from each other and outside the two fixing rods 19. Both ends of the two buffer springs 23 are respectively fixedly connected to the bottom plate 3 and the second auxiliary block 21. By providing the two support plates 20 to rotate synchronously and in opposite directions, the two sliding plates 22 move away from each other, and thus the two buffer springs 23 are compressed. At the same time, the buffer springs 23 provided achieve the effect of buffering and shock absorption in the horizontal direction of the device.

[0025] Sliding plates 22 are fixedly installed at the bottoms of both of the two second auxiliary blocks 21. The sliding plates 22 are slidably connected to the sliding grooves 18. Wear-resistant coatings are provided on the surfaces of the outer cylinder 5 and the reinforcing column 8 that are close to each other. By providing the sliding plates 22, the lateral movement position of the second auxiliary blocks 21 is restricted, further restricting the minimum distance after compression between the bottom plate 3 and the top plate 4, preventing damage to the compression spring 9 and the buffer spring 23 caused by excessive extrusion, and by providing wear-resistant coatings on the surfaces of the outer cylinder 5 and the reinforcing column 8 that are close to each other, the wear caused by the movement of the reinforcing column 8 and the sleeve column 10 is reduced.

[0026] In summary, for the cavity support structure of the modified nylon, during use, a number of second fixing bolts 16 are provided on the sides of the bottom plate 3 and the top plate 4 that are close to each other. Through the action of the number of second fixing bolts 16 provided on one side of the bottom plate 3, the bottom plate 3 is connected to the inner reinforcing body 2, and thus the movement of the inner reinforcing body 2 can drive the bottom plate 3 to move together. Through the action of the number of second fixing bolts 16 provided on one side of the top plate 4, the top plate 4 is connected to the nylon cavity support body 1, and thus the movement of the nylon cavity support body 1 can drive the bottom plate 3 to move together. At the same time, when the nylon cavity support body 1 is squeezed, the top plate 4 moves downward to drive the sleeve column 10 to move longitudinally. Through the cooperation of the provided reinforcing column 8 and the limiting plate 11, the detachment and deviation of the compression spring 9 during the buffering process of the device are avoided. At the same time, through the provided T-shaped limiting rod 14, the sleeve column 10 is further prevented from driving the compression spring 9 to rotate during longitudinal movement, reducing the possibility of damage to the compression spring 9.

[0027] At the same time, the provided sleeve column 10 slides between the outer cylinder 5 and the reinforcing column 8, and the provided compression spring 9 slides outside the reinforcing column 8, thereby reducing the possibility of deformation and damage to the outer cylinder 5 and the first fixing plate 6 due to force. At the same time, the first fixing bolts 13 that are hidden are threadedly connected to both the first fixing plate 6 and the second fixing plate 7. By squeezing the first fixing plate 6 and the second fixing plate 7, it is convenient to disassemble and replace them from the bottom plate 3 and the top plate 4, so as to facilitate their maintenance and replacement. By providing wear-resistant coatings on the surfaces of the outer cylinder 5 and the reinforcing column 8 that are close to each other, the wear caused by the movement of the reinforcing column 8 and the sleeve column 10 is reduced. At the same time, the provided sound-absorbing cotton 12 is flexible and can be compressed. By providing the sound-absorbing cotton 12, it plays a role in buffering the compression spring 9, blocking abnormal sounds emitted by the compression spring 9, and achieving the effect of sound absorption and noise reduction.

[0028] When the distance between the bottom plate 3 and the top plate 4 is further reduced by moving the nylon cavity support body 1 and the inner reinforcing body 2, longitudinal buffering and shock absorption are carried out through the arranged compression spring 9. At the same time, the two arranged support plates 20 rotate synchronously in the opposite direction, so that the two sliding plates 22 move away from each other, and further the two buffer springs 23 are compressed. At the same time, the arranged buffer springs 23 achieve the effect of buffering and shock absorption in the horizontal direction of the device, improving the practicability of the device.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
