Description

Technical Field

[0001] This utility model relates to the field of sponge sheath technology, specifically to a sponge sheath with strong resistance to deformation. Background Technology

[0002] Sponge sleeves are common items in daily life and production processes. They can be installed on the outer walls of pipes, cables, support rods, and other structures to effectively provide protection. Sponge sleeves typically have functions such as fire resistance, heat insulation, impact resistance, and cushioning, making them convenient for users to use according to different needs.

[0003] A cleanroom pipeline anti-collision sleeve, with publication number CN215674274U, includes a first protective sleeve and a second protective sleeve. The first protective sleeve is rotatably connected to the second protective sleeve via a connecting rod. Both the first and second protective sleeves have shock-absorbing sleeves on their inner rings. Each shock-absorbing sleeve is semi-circular, and each shock-absorbing sleeve has several sets of compression springs arranged circumferentially on its outer ring. Each set of compression springs has several springs arranged along the horizontal direction of the shock-absorbing sleeve. This enhances the buffering capacity, effectively resisting large impacts, preventing pipeline deformation, and avoiding pipeline breakage.

[0004] The aforementioned existing technology has some defects in actual use. The buffer structure of the device only has a simple spring and lacks a buffer structure to prevent the spring from rebounding back and forth. As a result, when the device is subjected to external impact, the spring will shake back and forth and cannot stop in time, affecting the inner ring shock-absorbing sleeve and thus affecting the normal use of the device. At the same time, the protective sleeves and shock-absorbing sleeves at both ends of the device are connected to each other. Therefore, when the device is squeezed, the top and bottom will transmit the impact force to the inner protective sleeve, which will further weaken the buffering effect of the spring. Utility Model Content

[0005] Therefore, this utility model provides a sponge sheath with strong deformation resistance to solve the problems of poor impact resistance and poor deformation resistance of sponge sheaths in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sponge sheath with strong deformation resistance includes a central ring, a connecting ring sleeved on the outer wall of the central ring, rubber rings installed at the top and bottom between the central ring and the connecting ring, and multiple arc-shaped plates fixedly connected to the outer wall of the central ring.

[0008] Multiple support columns are installed through the inside of the rubber ring, and multiple mounting holes corresponding to the support columns are opened inside the rubber ring.

[0009] An anti-slip ring is fixedly connected inside the central ring, and a support ring is fixedly connected to the outer wall of the sleeve ring.

[0010] A blocking strip is provided at the center of the outer wall of the sleeve ring. Both ends of the blocking strip are fixedly connected to mounting plates, and a fixing screw is threaded between the two mounting plates.

[0011] Furthermore, both sides of the arc-shaped plate are bent toward the outer wall of the central ring and fixed to the outer wall of the central ring, and the outer wall at the center of one side of the arc-shaped plate is fitted and fixed to the inner wall of the sleeve ring.

[0012] Furthermore, the inner wall of the rubber ring is fixedly connected to the outer wall of the central ring, and the outer wall of the rubber ring is fixedly connected to the inner wall of the sleeve ring.

[0013] Furthermore, both ends of the outer wall of the support column penetrate the interior of the mounting hole and are fixedly connected to the rubber ring. Both sides of the outer wall of the support column are in contact with the outer wall of the arc plate, and multiple support columns are spaced apart from the arc plate.

[0014] Furthermore, the inner wall of the blocking strip is fitted to the outer wall of the support ring, and both sides of the blocking strip away from the support ring are inclined towards the center. The surface of the support ring is provided with a waterproof coating.

[0015] Furthermore, one side of the rubber ring is fixedly attached to one end of the arc-shaped plate, the interior of the arc-shaped plate is filled with gas, and the side of the arc-shaped plate near the central ring is fixedly connected to the central ring and the rubber ring to form a sealing structure.

[0016] Furthermore, the support column is made of plastic, and the outer wall of the support column is attached to and slidably connected to the outer wall of the arc-shaped plate.

[0017] Furthermore, the inner wall of the anti-slip ring is provided with anti-slip texture, and the inner wall of the central ring is provided with an annular groove corresponding to the anti-slip ring.

[0018] This utility model has the following advantages:

[0019] 1. The impact is blocked by the blocking strip, which then transmits the impact force to the support ring. From there, it is transmitted to the connecting ring, which in turn moves multiple support columns toward the central ring. This causes the connecting ring and the support columns to press against the arc-shaped plate, deforming it. Since the side of the arc-shaped plate closest to the central ring is filled with air, the air is compressed, thus providing cushioning. Furthermore, because both sides of the arc-shaped plate are fixedly connected to the connecting ring, the impact force is further dispersed and transmitted to the outer wall of the central ring, causing the central ring to be compressed as well. This further distributes the impact force and protects the internal equipment of the central ring.

[0020] 2. The compressed air will rebound, causing the arc-shaped plate to move in the opposite direction. At the same time, the arc-shaped plate itself will also rebound under the action of elasticity, thus squeezing the sleeve ring. The rebound between the two arc-shaped plates can also push the support column away from the central ring. The reverse movement of the support column provides further support for the sleeve ring, preventing the sleeve ring from failing to rebound and thus restoring the external shape of the sleeve ring. Furthermore, since the outer wall of the sleeve ring is also provided with a support ring, and the outer wall of the support ring is fixedly connected with a blocking strip, the blocking strip can further pull the sleeve ring in the opposite direction through the support ring, so that the sleeve ring returns to its original shape, effectively improving the deformation resistance of the device.

[0030] refer to Figure 1-5 The sponge sheath shown has strong deformation resistance and includes a central ring 1. A connecting ring 2 is sleeved on the outer wall of the central ring 1. Rubber rings 3 are installed at the top and bottom between the central ring 1 and the connecting ring 2. Multiple arc-shaped plates 5 are fixedly connected to the outer wall of the central ring 1. Multiple support columns 301 are installed through the inside of the rubber ring 3. Multiple mounting holes 302 corresponding to the support columns 301 are opened inside the rubber ring 3. An anti-slip ring 101 is fixedly connected inside the central ring 1. A support ring 201 is fixedly connected to the outer wall of the connecting ring 2. A blocking strip 4 is provided at the center of the outer wall of the connecting ring 2. Mounting pieces 401 are fixedly connected to both ends of the blocking strip 4. A fixing screw 402 is threaded between the two mounting pieces 401.

[0031] Rotating the fixing screw 402 causes the mounting pieces 401 to move closer together, thereby pressing the blocking strip 4 into the interior of the device. This allows the interior of the device to fit tightly against the outer wall of the equipment. When subjected to external impact, the blocking strip 4, located outside the sleeve ring 2, can easily block the impact. Since the side of the arc-shaped plate 5 closest to the central ring 1 is filled with air, the air is compressed, thus providing cushioning. Furthermore, because both sides of the arc-shaped plate 5 are fixedly connected to the sleeve ring 2, the arc-shaped plate 5 can further disperse and transmit the impact force to the central ring 2. At the outer wall of the core ring 1, the core ring 1 is also compressed, thereby further distributing the impact force and protecting the internal equipment of the core ring 1. The compressed air will rebound, causing the arc plate 5 to move in the opposite direction. At the same time, the arc plate 5 itself will also rebound under the action of elasticity, thereby causing the arc plate 5 to compress the sleeve ring 2. Meanwhile, the rebound between the two arc plates 5 can also push the support column 301 away from the core ring 1. The reverse movement of the support column 301 provides further support for the sleeve ring 2, preventing the sleeve ring 2 from failing to rebound, thereby restoring and maintaining the external shape of the sleeve ring 2.

[0032] refer to Figure 3 , Figure 4As shown, both sides of the arc plate 5 are bent towards the outer wall of the central ring 1 and fixed to the outer wall of the central ring 1. The outer wall at the center of one side of the arc plate 5 is attached and fixed to the inner wall of the sleeve ring 2. One side of the rubber ring 3 is attached and fixed to one end of the arc plate 5. The arc plate 5 is filled with gas, and the side of the arc plate 5 near the central ring 1 is fixedly connected to the central ring 1 and the rubber ring 3 to form a sealed structure. This allows the sleeve ring 2 and multiple support columns 301 to squeeze the arc plate 5 together, causing the arc plate 5 to be squeezed and deformed. Since the side of the arc plate 5 near the central ring 1 is filled with air, the air is compressed, thus achieving buffering. At the same time, since both sides of the arc plate 5 are fixedly connected to the sleeve ring 2, the arc plate 5 can further disperse and transmit the impact force to the outer wall of the central ring 1, causing the central ring 1 to be squeezed as well, thereby further distributing the impact force and protecting the internal equipment of the central ring 1.

[0033] refer to Figure 2 , Figure 5 As shown, the inner wall of the rubber ring 3 is fixedly connected to the outer wall of the central ring 1, and the outer wall of the rubber ring 3 is fixedly connected to the inner wall of the sleeve ring 2. The outer walls of both ends of the support column 301 penetrate the interior of the mounting hole 302 and are fixedly connected to the rubber ring 3. The outer walls of the support column 301 are attached to the outer walls of the arc plate 5 on both sides. Multiple support columns 301 are spaced apart from the arc plate 5. The support column 301 is made of plastic, and the outer wall of the support column 301 is attached to and slidably connected to the outer wall of the arc plate 5. The rebound between the two arc plates 5 can also push the support column 301 away from the central ring 1. The reverse movement of the support column 301 further supports the sleeve ring 2, avoiding the situation where the sleeve ring 2 cannot rebound, thereby restoring and maintaining the external shape of the sleeve ring 2.

[0034] refer to Figure 2 , Figure 5 As shown, the inner wall of the blocking strip 4 is fitted with the outer wall of the support ring 201. The two sides of the blocking strip 4 away from the support ring 201 are inclined towards the center. The surface of the support ring 201 is provided with a waterproof coating. Since the blocking strip 4 is set outside the sleeve ring 2, it can easily block the impact and then transmit the impact force to the support ring 201. The blocking strip 4 is fixedly connected to the outer wall of the support ring 201. Therefore, the blocking strip 4 can also further pull the sleeve ring 2 to move in the opposite direction through the support ring 201, so that the sleeve ring 2 returns to its original shape, effectively improving the deformation resistance of the device.

[0035] refer to Figure 1 , Figure 4 As shown, the inner wall of the anti-slip ring 101 is provided with anti-slip texture, and the inner wall of the central ring 1 is provided with an annular groove corresponding to the anti-slip ring 101. The anti-slip ring 101 can effectively prevent the central ring 1 from sliding off the equipment.

[0036] Working Principle: During use, the device can be easily fitted onto the outer wall of the equipment requiring protection. Simultaneously, rotating the fixing screw 402 allows the mounting pieces 401 to move closer together, thereby pressing the blocking strip 4 into the device. This ensures a tight fit between the device's interior and the equipment's outer wall. Upon external impact, the blocking strip 4, located outside the sleeve ring 2, effectively blocks the impact. The impact force is then transmitted to the support ring 201, and subsequently to the sleeve ring 2. The connecting ring 2 causes multiple support columns 301 to move towards the central ring 1, allowing the connecting ring 2 and the multiple support columns 301 to press together the arc plate 5, causing the arc plate 5 to be compressed and deformed. Since the side of the arc plate 5 closest to the central ring 1 is filled with air, the air is compressed, thus achieving buffering. At the same time, since both sides of the arc plate 5 are fixedly connected to the connecting ring 2, the arc plate 5 can further disperse and transmit the impact force to the outer wall of the central ring 1, causing the central ring 1 to be compressed as well, thereby further distributing the impact force and protecting the internal equipment of the central ring 1.

[0037] After the impact and compression of the device are completed, the compressed air will rebound, causing the arc plate 5 to move in the opposite direction. At the same time, the arc plate 5 itself will also rebound under the action of elasticity, thus squeezing the sleeve ring 2. The rebound between the two arc plates 5 can also push the support column 301 away from the central ring 1. The reverse movement of the support column 301 provides further support for the sleeve ring 2, preventing the sleeve ring 2 from failing to rebound, thereby restoring the external shape of the sleeve ring 2. Furthermore, since the outer wall of the sleeve ring 2 is also provided with a support ring 201, and the outer wall of the support ring 201 is fixedly connected with a blocking strip 4, the blocking strip 4 can also further pull the sleeve ring 2 in the opposite direction through the support ring 201, so that the sleeve ring 2 returns to its original shape, effectively improving the deformation resistance of the device.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
