Description

Technical Field

[0001] This utility model relates to heat shrink tubing, specifically to an oil-resistant heat shrink tubing. Background Technology

[0002] Oil-resistant heat-shrink tubing is a highly efficient protective material designed for oily environments in the industrial field. It is made of special polymers such as modified polyolefins and fluoroplastics and processed through advanced cross-linking technology. It has excellent oil resistance, insulation, mechanical strength and flame retardancy. It can resist the corrosion of various oils, prevent equipment cables from leaking and short-circuiting, resist vibration and friction damage, and reduce the risk of fire. It is widely used in industries such as petrochemicals and automobile manufacturing. This type of tubing is usually stored and installed on a wheel. When in use, the appropriate length is simply pulled out from the wheel according to actual needs, cut, and then it can be put on the target area and heated to shrink and form a shape to achieve reliable protection.

[0003] However, when using existing heat shrink tubing, it is not convenient to install new tubing into the reel after the tubing is used up. This causes the tubing to easily become tangled or wrinkled during use, requiring repeated adjustments when inserting new tubing into the reel, thus affecting the ease of use of the tubing. Utility Model Content

[0004] The purpose of this utility model is to provide an oil-resistant heat shrink tubing. By setting a replacement part, it solves the problem that in the process of using existing heat shrink tubing, it is not convenient to install a new tubing in the wheel after the tubing is used up. This causes the heat shrink tubing to easily become tangled and wrinkled during use, and the position of the new tubing needs to be repeatedly adjusted when inserting it into the wheel, thus affecting the convenience of using the tubing.

[0005] To solve the above problems, this utility model provides an oil-resistant heat shrink tubing, including a wheel, and further including: a replacement part located inside the wheel; two clamping parts, both of which are installed inside the wheel; the replacement part includes a replacement component located inside the wheel; and a protective component located inside the wheel; the replacement component includes a connecting block fixedly connected to the inner wall of the wheel, a rotating ring rotatably connected to the outer wall of the connecting block, a tube disposed outside the rotating ring, a sleeve wound around the outer wall of the tube, a plurality of slots I on the inner wall of the rotating ring, a locking block I slidably connected to the inner wall of the connecting block, a spring I fixedly connected to the bottom of the locking block I, the bottom of the spring I fixedly connected to the connecting block, the locking block I matching the plurality of slots I, and the plurality of slots I being circumferentially distributed.

[0006] In one possible implementation, the clamping part includes a clamping assembly disposed within the wheel; and an elastic assembly mounted within the wheel.

[0007] In one possible implementation, the protective component includes a protective shell disposed within a connecting block. The inner wall of the connecting block has two slots, each slot having an elastic element. The two elastic elements are mirror images of each other. Each elastic element includes a locking block slidably connected to the inner wall of the protective shell. A spring is fixedly connected to the side of the locking block away from the slots, and the side of the spring away from the locking block is fixedly connected to the protective shell. The locking block and the slots are compatible.

[0008] In one possible implementation, the clamping assembly includes a groove formed within a wheel, an inverted block slidably connected to the inner wall of the groove, a rolling element disposed within the inverted block, the rolling element being used to ensure smooth pull-out of the sleeve, the rolling element including a rotating shaft rotatably connected to the inner wall of the inverted block, a roller fixedly connected to the outer wall of the rotating shaft, the side of the roller away from the inverted block contacting the sleeve.

[0009] In one possible implementation, the elastic assembly includes two limiting rods slidably connected to the inner wall of the wheel. The side of each limiting rod closest to the C-shaped block is fixedly connected to the C-shaped block, and the side of each limiting rod furthest from the C-shaped block is fixedly connected to a limiting plate. A spring is provided on the outside of each limiting rod, and the two limiting rods are mirror images of each other. The spring includes a third spring sleeved on the outer wall of the limiting rod. The side of the third spring closest to the limiting plate is fixedly connected to the limiting plate, and the side of the third spring closest to the C-shaped block is fixedly connected to the wheel.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following advantages: 1. By setting up a replacement part, the protective shell of the replacement part can be inserted and removed in the connecting block during replacement. The second locking block and the second locking groove cooperate to fix and unlock the protective shell. The tube is sleeved on the rotating ring and is locked by the protrusion. The first locking block and the first locking groove cooperate to limit the rotation state of the rotating ring under the action of the first spring. This can easily realize the replacement and fixation of the sleeve, while protecting the related components and preventing the rotating ring from rotating on its own. This ensures the stability of the sleeve during the replacement process and eliminates the need for staff to repeatedly adjust the position, thus ensuring the convenience of using the sleeve. 2. By setting a clamping part, when in use, the sleeve of the clamping part squeezes the roller, and the roller drives the C-shaped block to slide in the groove through the rotating shaft. The limiting rod drives the limiting plate to stretch or compress the spring. The roller contacts the sleeve, and the elastic force of the spring realizes the squeezing and limiting of the sleeve. This can ensure the smoothness of the sleeve when it is pulled out. After the sleeve reaches the use standard and is cut off, it can effectively prevent the sleeve from retracting back to the wheel, ensuring the stability of the sleeve position during use, thereby further ensuring the convenience of the sleeve use.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

These elastic elements are mirror images of each other. Each elastic element includes a locking block 223 slidably connected to the inner wall of the protective shell 221. A spring 224 is fixedly connected to the side of the locking block 223 away from the slot 222, and the side of the spring 224 away from the locking block 223 is fixedly connected to the protective shell 221. The locking block 223 and the slot 222 are compatible. By providing the replacement part 2, the sleeve 214 can be easily replaced and fixed, while also protecting related components and preventing the rotating ring from rotating on its own, ensuring the stability of the sleeve 214 during replacement. This eliminates the need for repeated adjustments by personnel, thus ensuring the ease of use of the sleeve 214.

[0018] In this embodiment, the clamping part 3 includes a clamping assembly 31 disposed within the wheel 101; and an elastic assembly 32 installed within the wheel 101. The clamping assembly 31 includes a groove 311 formed within the wheel 101, with a U-shaped block 312 slidably connected to the inner wall of the groove 311. A rolling element is disposed within the U-shaped block 312, and the rolling element is used to ensure the smooth pull-out of the sleeve 214. The rolling element includes a rotating shaft 313 rotatably connected to the inner wall of the U-shaped block 312, and a roller 314 fixedly connected to the outer wall of the rotating shaft 313. The side of the roller 314 away from the U-shaped block 312 contacts the sleeve 214. The elastic assembly 32 includes two limiting rods 321 slidably connected to the inner wall of the wheel 101, with the two limiting rods 321 close to the U-shaped block 312. Both are fixedly connected to the C-shaped block 312. The side of the two limiting rods 321 away from the C-shaped block 312 is fixedly connected to the limiting plate 322.

The spring includes a spring 323 sleeved on the outer wall of the limiting rod 321. The side of the spring 323 near the limiting plate 322 is fixedly connected to the limiting plate 322. The side of the spring 323 near the C-shaped block 312 is fixedly connected to the wheel 101. By setting the clamping part 3, the smoothness of the sleeve 214 when it is pulled out can be guaranteed. After the sleeve 214 reaches the use standard and is cut off, it can effectively prevent the sleeve 214 from retracting into the wheel 101, ensuring the stability of the sleeve 214 when in use, thereby further ensuring the convenience of using the sleeve 214.

[0019] A specific application of this embodiment is as follows: During use, the protective shell 221 can be pulled out of the connecting block 211. At this time, the second locking block 223 will slide into the protective shell 221 under the action of the second locking groove 222. Subsequently, the second spring 224 will compress and generate elastic force. After the protective shell 221 is pulled out, the second locking block 223 will reset under the elastic force of the second spring 224. Then, the tube 213 of the sleeve 214 on the disc can be placed on the rotating ring 212 and held in place by the multiple protrusions on the rotating ring 212. Then, the end of the sleeve 214 can be pulled and locked between the two rollers 314. At this time, the sleeve 214 will squeeze the rollers 314, causing them to drive the C-shaped block 312 to slide in the sliding groove 311 via the rotating shaft 313. At this time, under the action of the limiting rod 321, the third spring 323 will be stretched through the limiting plate 322, generating elastic force. Then, the protective shell 221 can be inserted into the connecting block. Within 211, the second locking block 223 is engaged into the second locking slot 222, thus completing the fixation. When the sleeve 214 is needed, it can be pulled to make the rotating ring 212 rotate through the tube 213. At this time, under the action of the first locking slot 215, the first locking block 216 will slide into the connecting block 211, thereby compressing the first spring 217 and generating elastic force. Under the action of this elastic force, the rotating ring 212 will be prevented from rotating on its own, while the sleeve 214... When the sleeve 214 is pulled out of the wheel 101, it will cause the roller 314 to roll, thus ensuring the smoothness of the sleeve 214 being pulled out. When the pulled-out sleeve 214 meets the usage standard, it can be cut off. Under the action of the spring 323, the sleeve 214 will be squeezed by the limiting rod 321 driven by the limiting plate 322 through the limiting plate 322, thereby driving the roller 314 through the rotating shaft 313 to squeeze the sleeve 214 and prevent it from retracting into the wheel 101.
