Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parts, and in particular to a vehicle-use limiting rubber sleeve. The present invention also relates to a vehicle provided with the vehicle-use limiting rubber sleeve. Background Art

[0002] During the driving process of a car, due to the bumps of the road, the vibration of the engine and various dynamic loads, two adjacent parts may move relative to each other. Therefore, a limit rubber sleeve is usually provided between two adjacent products. When the two products move relative to each other, the product first contacts the limit rubber sleeve, and the elasticity of the limit rubber sleeve prevents bumps and abnormal noises. At the same time, it can also limit the displacement of the product and prevent the two parts from directly contacting each other.

[0003] However, the length of the limiting rubber sleeve in the prior art is usually not adjustable. Whenever the surrounding components change, it is necessary to redevelop products of different lengths. This means that additional design, mold opening, production and other costs need to be invested. In addition, as the product ages, the height of the limiting rubber sleeve will also decrease. This may result in the inability to achieve the original design function, and it is impossible to effectively prevent bumps and abnormal noises, limit displacement and maintain the posture of components. Moreover, the failure of the limiting rubber sleeve will not only affect the performance and comfort of the car, but may also pose a potential threat to driving safety. Summary of the invention

[0004] In view of this, the present invention aims to provide a vehicle-use limiting rubber sleeve, whose outer protrusion distance is adjustable, which can save mold opening costs and effectively prevent the failure of the limiting function.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A vehicle-use limiting rubber sleeve comprises a mounting base, a rubber sleeve frame arranged on the mounting base, and a rubber sleeve arranged on the rubber sleeve frame;

[0007] One end of the rubber sleeve skeleton is connected to the mounting base, and the other end of the rubber sleeve skeleton is arranged to protrude relative to the mounting base. The rubber sleeve is arranged on the protruding end of the rubber sleeve skeleton, and the rubber sleeve skeleton is driven to move relative to the mounting base to adjust the protruding distance of the rubber sleeve skeleton.

[0008] Furthermore, one end of the rubber sleeve frame is threadedly connected to the mounting base, and the rubber sleeve frame is driven to rotate relative to the mounting base, so that the protruding distance of the rubber sleeve frame can be adjusted.

[0009] Furthermore, an anti-loosening mechanism is provided between the mounting base and the rubber sleeve frame, and the anti-loosening mechanism is used to limit the rotation of the rubber sleeve frame relative to the mounting base to maintain the outward protrusion distance of the rubber sleeve frame.

[0010] Furthermore, the anti-loosening mechanism includes an anti-rotation block provided in the mounting base, an elastic member provided between the anti-rotation block and the mounting base, and a matching block provided on the rubber sleeve frame;

[0011] The anti-rotation block is slidably arranged along the axial direction of the rubber sleeve frame, and a first ratchet unit is arranged on the anti-rotation block, and a second ratchet unit is arranged on the matching block. Under the push of the elastic member, the first ratchet unit is meshed with the second ratchet unit.

[0012] Furthermore, the mounting base includes a base body connected to the rubber sleeve frame, and a cylinder located at one end of the base body;

[0013] The anti-rotation block and the elastic member are arranged in the cylinder, and an operating handle is arranged on the anti-rotation block. The operating handle extends out from the notch on the cylinder and constrains the anti-rotation block to slide along the axial direction of the rubber sleeve frame.

[0014] Furthermore, the anti-rotation block is annular and is sleeved on the rubber sleeve frame, and the operating handles are multiple and spaced apart along the circumference of the anti-rotation block, and each operating handle extends out from a corresponding notch.

[0015] Furthermore, the rubber sleeve is arranged on the rubber sleeve frame, and an anti-slip portion and / or a limiting portion is provided between the rubber sleeve and the rubber sleeve frame;

[0016] The anti-dropping portion is used to limit the rubber sleeve from falling off the rubber sleeve frame, and the limiting portion is used to limit the rotation of the rubber sleeve relative to the rubber sleeve frame.

[0017] Further, the anti-slip portion comprises an anti-slip ring provided on the rubber sleeve frame, and at least a part of the anti-slip ring is embedded in the rubber sleeve; and / or,

[0018] The limiting portion comprises a limiting block arranged on the rubber sleeve frame, the limiting block extends along the sleeve direction of the rubber sleeve and is embedded in the rubber sleeve.

[0019] Furthermore, the mounting base is provided with a mounting end, and the mounting end is provided with an external thread to form a stud structure.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] The vehicle-use limiting rubber sleeve of the present invention is configured such that one end of the rubber sleeve skeleton is convexly arranged relative to the mounting base, and the rubber sleeve is arranged at the convex end, thereby connecting the mounting base with one of its components, and making the rubber sleeve abut against another component, thereby limiting the relative movement between the two components, and utilizing the good elasticity of the rubber sleeve to prevent collision and abnormal noise. In addition, the skeleton is driven to move relative to the mounting base to adjust the convex distance of the rubber sleeve skeleton, thereby being used to limit different distances of different products, avoiding the need to open new molds and saving production costs. At the same time, as the rubber sleeve ages, the convex distance of the rubber sleeve skeleton can be adjusted to maintain the limiting function of the original design, thereby avoiding limiting failure.

[0022] In addition, one end of the rubber sleeve skeleton is screwed to the mounting base, and the protruding distance of the rubber sleeve skeleton is adjusted by driving the rubber sleeve skeleton to rotate relative to the mounting base. This not only improves the connection firmness between the rubber sleeve skeleton and the mounting base, but also facilitates the adjustment of the protruding distance of the rubber sleeve skeleton and the disassembly and maintenance of the rubber sleeve skeleton.

[0023] Secondly, by arranging an anti-loosening mechanism between the mounting base and the rubber sleeve frame, the rubber sleeve frame can be prevented from rotating relative to the mounting base, while the protruding distance of the rubber sleeve frame can be maintained. This can avoid the accidental rotation of the rubber sleeve frame relative to the mounting base due to continuous vibration, bumps and various complex forces during the operation of the vehicle, and can prevent the limiting effect of the vehicle's limiting rubber sleeve on the two components from failing.

[0024] Furthermore, the anti-return loosening mechanism includes an anti-rotation block, an elastic member, and a matching block arranged on the rubber sleeve frame, and a first ratchet unit is provided on the anti-rotation block, and a second ratchet unit meshing with the first ratchet unit is provided on the matching block, thereby effectively preventing the rubber sleeve frame from accidentally rotating during the operation of the vehicle; moreover, when it is necessary to adjust the protruding distance of the rubber sleeve frame, it is only necessary to overcome the force of the elastic member and separate the anti-rotation block from the matching block to perform the adjustment operation, which is simple to operate and does not require complicated tools or techniques, and after the adjustment is completed, the elastic member will automatically push the anti-rotation block to re-engage with the matching block without the need for additional operations, thereby improving work efficiency.

[0025] In addition, the anti-rotation block and the elastic part are arranged in the cylinder to protect them from the influence of the external environment. The setting of the operating handle can conveniently operate the anti-rotation block. At the same time, the operating handle extends from the groove on the cylinder and constrains the anti-rotation block to slide axially along the rubber sleeve frame, which can ensure that the anti-rotation block will not deviate from the axial movement during operation, thereby ensuring the reliability of the anti-loosening mechanism.

[0026] By setting the anti-rotation block in a ring shape, the force on the anti-rotation block in all directions can be more evenly distributed. The provision of multiple operating handles can also more firmly fix the position of the anti-rotation block. Therefore, during driving, even if the anti-rotation block is subjected to vibration and impact forces in different directions, it can remain stable without displacement or deformation, thereby ensuring the reliability of the anti-loosening mechanism. At the same time, the operating handle can also be operated at different positions to facilitate adjustment of the protruding distance of the rubber sleeve frame.

[0027] In addition, by setting the anti-slipping part, the rubber sleeve can be effectively restricted from falling off the rubber sleeve frame, and the setting of the limiting part can effectively prevent the rubber sleeve from rotating, ensuring that the limiting rubber sleeve can always maintain the correct working position. The anti-slipping part includes an anti-slipping ring arranged on the rubber sleeve frame, and at least part of the anti-slipping ring is embedded in the rubber sleeve, which has a simple structure and can increase the connection strength between the rubber sleeve and the rubber sleeve frame, preventing the rubber sleeve from falling off the rubber sleeve frame when subjected to external force; and the limiting part includes a limiting block extending along the sleeve direction of the rubber sleeve, which has a simple structure, and when the rubber sleeve is subjected to lateral force or torsional force, the limiting block will interact with the structure inside the rubber sleeve to generate resistance, which can effectively prevent the rotation of the rubber sleeve and has a good limiting effect.

[0028] In addition, by providing an external thread forming a stud structure on the mounting end of the mounting base, the connection between the mounting base and the vehicle is facilitated, and the threaded connection is simple to operate and can provide a relatively firm connection, ensuring that the limiting rubber sleeve will not easily loosen or fall off during the operation of the vehicle; at the same time, it is also easy to disassemble and repair the vehicle limiting rubber sleeve.

[0029] Another object of the present invention is to provide a vehicle, on which the vehicle limiting rubber sleeve as described above is provided.

[0030] The vehicle described in the present invention can be used to limit different distances of different products by providing the vehicle limiting rubber sleeve as described above, thereby avoiding the need for opening new molds and saving production costs. At the same time, the limiting function of the original design can be maintained by adjusting the protruding distance of the rubber sleeve frame to avoid limiting failure, thereby improving the use effect of the vehicle.

[0052] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0053] Embodiment 1

[0054] The length of the limiting rubber sleeve in the prior art is usually not adjustable, and every time the surrounding components change, it is necessary to redevelop products of different lengths. Therefore, it is necessary to invest additional costs in design, mold opening, production, etc. In addition, as the product ages, the height of the limiting rubber sleeve will also decrease, which may make it impossible to achieve the original design function and cause the limit to fail. Therefore, this embodiment specifically proposes a new type of vehicle limiting rubber sleeve, which, in terms of overall structure, includes a mounting base 1, a rubber sleeve frame 4 provided on the mounting base 1, and a rubber sleeve 2 provided on the rubber sleeve frame 4.

[0055] Among them, one end of the rubber sleeve skeleton 4 is connected to the mounting base 1, and the other end of the rubber sleeve skeleton 4 is convexly arranged relative to the mounting base 1. The rubber sleeve 2 is arranged at the convex end of the rubber sleeve skeleton 4, and the rubber sleeve skeleton 4 is driven to move relative to the mounting base 1 to adjust the protruding distance of the rubber sleeve skeleton 4.

[0056] The vehicle-use limiting rubber sleeve of this embodiment is configured such that one end of the rubber sleeve skeleton 4 is convexly arranged relative to the mounting base 1, and the rubber sleeve 2 is arranged at the convex end, thereby connecting the mounting base 1 with one of its components, and making the rubber sleeve 2 abut against another component, thereby limiting the relative movement between the two components, and preventing the occurrence of knocks and abnormal noises by utilizing the good elasticity of the rubber sleeve 2. In addition, the rubber sleeve skeleton 4 is driven to move relative to the mounting base 1, and the convex distance of the rubber sleeve skeleton 4 can be adjusted, thereby being used for limiting different distances of different products, avoiding the need to open new molds, and saving production costs. At the same time, as the rubber sleeve 2 ages, the convex distance of the rubber sleeve skeleton 4 can be adjusted to maintain the limiting function of the original design, thereby avoiding limiting failure.

[0057] Based on the above overall introduction, an exemplary structure of the vehicle limiting rubber sleeve of this embodiment is referred to Figures 1 to 4 As shown in , the vehicle-use limiting rubber sleeve is cylindrical in shape as a whole, and, as a preferred embodiment, as the rubber sleeve frame 4 moves relative to the mounting base 1, at least part of the rubber sleeve 2 is always located in the mounting base 1, so as to improve the overall aesthetics while better protecting the rubber sleeve 2 and effectively preventing it from falling off from the rubber sleeve frame 4 due to external force. It is understandable that when the outer protrusion distance of the rubber sleeve frame 4 is large, it is also feasible to make the rubber sleeve 2 completely exposed outside the mounting base 1.

[0058] In addition, as a preferred embodiment, the mounting base 1 of this embodiment is provided with a mounting end, and the mounting end is provided with an external thread to form a stud structure. By providing an external thread on the mounting end, the connection between the mounting base 1 and the vehicle can be facilitated. In addition, the threaded connection is simple to operate and can provide a relatively firm connection, ensuring that the limiting rubber sleeve will not easily loosen or fall off during the operation of the vehicle; at the same time, it can also facilitate the disassembly and maintenance of the vehicle limiting rubber sleeve. In addition, during the specific implementation, the external thread on the mounting end can also adopt a standard thread specification, so that the vehicle limiting rubber sleeve has a strong versatility, which can make it suitable for the installation requirements of different vehicle models and vehicle parts, reducing the need for special customization due to mismatched mounting interfaces.

[0059] In addition, as a preferred mode, one end of the rubber sleeve frame 4 is screwed to the mounting base 1, and the rubber sleeve frame 4 is driven to rotate relative to the mounting base 1, so that the protruding distance of the rubber sleeve frame 4 can be adjusted. By screwing the rubber sleeve frame 4 to the mounting base 1, it can be ensured that the rubber sleeve frame 4 and the mounting base 1 will not be easily separated during the operation of the vehicle. In addition, it is also convenient to adjust the protruding distance of the rubber sleeve frame 4, and it is also convenient to disassemble and repair the rubber sleeve frame 4.

[0060] Based on this, combined Figure 5 and Figure 6As shown in , as a preferred embodiment, the mounting base 1 of this embodiment is cylindrical as a whole, and includes a base body 101 connected to the rubber sleeve skeleton 4, and a barrel 102 located at one end of the base body 101. Among them, the above-mentioned mounting end is composed of the base body 101, and an internal thread is provided in the base body 101 to be screwed to the rubber sleeve skeleton 4. The barrel 102 can be used to accommodate part of the rubber sleeve 2, so as to better protect the rubber sleeve 2 from damage. In addition, the outer diameter of the barrel 102 is larger than the outer diameter of the base body 101, so as to accommodate the following elastic parts and other components.

[0061] In addition, combined Figures 7 to 10 As shown in the figure, the rubber sleeve skeleton 4 of this embodiment is also in the shape of a round rod, one end of which is provided with an external thread screwed to the base body 101, and the other end is used to connect with the rubber sleeve 2. As a further embodiment, an anti-loosening mechanism is provided between the mounting base 1 and the rubber sleeve skeleton 4, and the anti-loosening mechanism is used to limit the rotation of the rubber sleeve skeleton 4 relative to the mounting base 1 to maintain the outer protrusion distance of the rubber sleeve skeleton 4.

[0062] During the operation of the vehicle, due to continuous vibration, bumps and various dynamic forces, the rubber sleeve frame 4 may rotate unexpectedly relative to the mounting base 1. By setting up an anti-loosening mechanism, the rotation of the rubber sleeve frame 4 can be effectively limited to ensure that the outer protrusion distance remains unchanged, thereby avoiding the limit failure of the limit rubber sleeve, which is conducive to ensuring the stability and safety of the vehicle.

[0063] In this embodiment, as a preferred implementation, the anti-return loosening mechanism of this embodiment includes an anti-rotation block 3 provided in the mounting base 1, an elastic member provided between the anti-rotation block 3 and the mounting base 1, and a matching block 401 provided on the rubber sleeve frame 4. In addition, the anti-rotation block 3 is slidably arranged along the axial direction of the rubber sleeve frame 4, and a first ratchet unit 301 is provided on the anti-rotation block 3, and a second ratchet unit 4011 is provided on the matching block 401. Under the push of the elastic member, the first ratchet unit 301 and the second ratchet unit 4011 are meshed together.

[0064] In this way, the first ratchet unit 301 and the second ratchet unit 4011 are designed so that the teeth can slide or separate relatively smoothly in one direction, but they will get stuck to each other in the opposite direction. Therefore, when the rubber sleeve frame 4 tries to rotate in the opposite direction relative to the mounting base 1, the inclined surfaces of the ratchets will conflict with each other to prevent the rotation from occurring, thereby effectively preventing the rubber sleeve frame 4 from accidentally rotating during the operation of the vehicle.

[0065] Among them, the anti-rotation block 3 is set to slide along the axial direction of the rubber sleeve skeleton 4, which can achieve engagement or separation with the matching block 401, and the elastic member can provide a thrust force so that the anti-rotation block 3 always maintains a tendency to contact with the matching block 401. Moreover, under the action of the elastic member, the first ratchet unit 301 and the second ratchet unit 4011 can be tightly engaged together to ensure the effectiveness of the anti-loosening mechanism. Moreover, when it is necessary to adjust the protruding distance of the rubber sleeve skeleton 4, the force of the elastic member can be overcome to separate the anti-rotation block 3 from the matching block 401. When the adjustment is completed, the elastic member will automatically push the anti-rotation block 3 to re-engage with the matching block 401, without the need for additional operations, which is convenient and quick.

[0066] like Figure 4 As shown, based on the above structure of the mounting base 1, the anti-rotation block 3 and the elastic member of this embodiment are arranged in the cylinder 102, and the anti-rotation block 3 is provided with an operating handle 302, which extends from the notch 1021 on the cylinder 102 and constrains the anti-rotation block 3 to slide along the axial direction of the rubber sleeve frame 4. Among them, as a specific embodiment, the elastic member is specifically a spring sleeved outside the rubber sleeve frame 4.

[0067] In this embodiment, by arranging the anti-rotation block 3 and the elastic member in the barrel 102, the anti-rotation block 3 and the elastic member can be protected from the influence of the external environment, and the service life can be extended. Moreover, the setting of the operating handle 302 can conveniently operate the anti-rotation block 3. At the same time, the operating handle 302 extends from the notch 1021 on the barrel 102, and constrains the anti-rotation block 3 to slide along the axial direction of the rubber sleeve skeleton 4, which can ensure that the anti-rotation block 3 will not deviate from the axial movement during the working process, and can ensure that the first ratchet unit 301 and the second ratchet unit 4011 can always maintain a good meshing state, which is conducive to ensuring the reliability of the anti-loosening mechanism.

[0068] As a preferred embodiment, Figure 4 and Fig.11 As shown in the figure, the anti-rotation block 3 of this embodiment is annular and is sleeved on the rubber sleeve frame 4, and the operating handles 302 are arranged at intervals along the circumference of the anti-rotation block 3, and each operating handle 302 extends out from the corresponding notch 1021. In addition, the first ratchet unit 301 is arranged on one side of the anti-rotation block 3 in the thickness direction, and includes a plurality of first ratchets arranged in sequence along the circumference thereof. Correspondingly, in combination with Figures 7 to 10 As shown in the figure, the matching block 401 of this embodiment is annular and adapted to the anti-rotation block 3, and the second ratchet unit 4011 is arranged on one side of the anti-rotation block 3 in the thickness direction thereof, and includes a plurality of second ratchets arranged in sequence along the circumference thereof. The matching block 401 can be integrally formed with the rubber sleeve frame 4, or welded together.

[0069] In this embodiment, by setting the anti-rotation block 3 into a ring shape, the good symmetry and uniform force characteristics of the ring structure can be utilized, so that when the anti-rotation block 3 cooperates with the rubber sleeve frame 4, a limiting force can be applied to the rubber sleeve frame 4 from all directions, effectively preventing the rubber sleeve frame 4 from unnecessary rotation, thereby better realizing the function of preventing re-loosening. And the operating handle 302 is set to be a plurality of circumferentially spaced along the anti-rotation block 3, not only when the anti-rotation block 3 is pulled by the operating handle 302, the anti-rotation block 3 can be subjected to a relatively uniform pulling force, avoiding deformation of the anti-rotation block 3 or jamming with the matching block 401 due to excessive force on a single point, but also facilitating the rapid release of the meshing of the first ratchet unit 301 and the second ratchet unit 4011, which can improve the adjustment efficiency. Moreover, the operator can adjust by holding the operating handle 302 at different positions, which can improve the convenience of operation.

[0070] In addition, since the operating handle 302 extends from the notch 1021, the operator can intuitively see the position and state of the operating handle 302, and can more accurately determine the position of the anti-rotation block 3. As a result, the protruding distance of the rubber sleeve frame 4 can be accurately adjusted, which can effectively avoid problems such as over-adjustment or under-adjustment caused by the inability to accurately grasp the position of the anti-rotation block 3. At this time, as a further implementation, a scale line extending along the length direction of the notch 1021 can also be set on the cylinder 102, so as to roughly obtain the length of the protruding distance by observing the matching position of the operating handle 302 and the scale line.

[0071] In addition, if Fig.11 As shown in the figure, as a specific implementation, the operating handles 302 of this embodiment are two correspondingly arranged on the anti-rotation block 3. Of course, in addition to being two, it is also feasible to set the operating handles 302 to three, four or other numbers evenly distributed along the circumference of the anti-rotation block 3. In this case, the notches 1021 arranged on the cylinder 102 of the mounting base 1 correspond to the number of the operating handles 302.

[0072] In addition, combined Figure 2 and Figure 4 As shown in , as a preferred embodiment, the rubber sleeve 2 of this embodiment is cylindrical, and the rubber sleeve 2 is sleeved on the rubber sleeve frame 4, and an anti-slip portion and a limiting portion are provided between the rubber sleeve 2 and the rubber sleeve frame 4. Among them, the anti-slip portion is used to limit the rubber sleeve 2 from falling off from the rubber sleeve frame 4, and the limiting portion is used to limit the rotation of the rubber sleeve 2 relative to the rubber sleeve frame 4. In this embodiment, by providing the anti-slip portion, the rubber sleeve 2 can be effectively limited from falling off from the rubber sleeve frame 4, and the setting of the limiting portion can effectively prevent the rotation of the rubber sleeve 2, ensuring that the limiting rubber sleeve can always maintain the correct working position.

[0073] Therefore, through the mechanical connection between the anti-slip part and the limiting part, the combination between the rubber sleeve 2 and the rubber sleeve frame 4 is tighter, and can withstand greater external force impact and vibration, reducing the risk of structural damage and functional failure caused by the falling off or rotation of the rubber sleeve 2, extending the service life of the limiting rubber sleeve, and thus reducing the maintenance cost of the vehicle.

[0074] Combined with Figure 4 and Figure 8 As shown in , as a specific embodiment, the anti-slip portion of this embodiment includes an anti-slip ring 402 provided on the rubber sleeve skeleton 4, and at least a portion of the anti-slip ring 402 is embedded in the rubber sleeve 2. Among them, as a preferred embodiment, the anti-slip ring 402 of this embodiment is conical. The annular structure of the anti-slip ring 402 has good continuity and integrity, and can form a relatively uniform protective ring around the rubber sleeve skeleton 4, effectively preventing the rubber sleeve 2 from falling off the rubber sleeve skeleton 4. In addition, embedding at least a portion of the anti-slip ring 402 in the rubber sleeve 2 can "lock" the rubber sleeve 2 on the rubber sleeve skeleton 4 to a certain extent, thereby strengthening the degree of bonding between the rubber sleeve 2 and the rubber sleeve skeleton 4.

[0075] It should be noted that the anti-slip part is provided Figure 8 The annular anti-slip ring 402 shown in the figure may also include a plurality of anti-slip protrusions arranged at intervals along the circumference of the rubber sleeve skeleton 4, and each anti-slip protrusion is embedded in the rubber sleeve skeleton 4. In addition, the anti-slip ring 402 may be set to a cylindrical shape in addition to a conical shape.

[0076] In addition, continue to refer to Figure 4 and Figure 8 As shown in , as a preferred embodiment, the limiting portion of this embodiment includes a limiting block 403 provided on the rubber sleeve frame 4, the limiting block 403 extends along the sleeve direction of the rubber sleeve 2, and is embedded in the rubber sleeve 2. Moreover, as a specific embodiment, the limiting block 403 of this embodiment extends from the free end of the rubber sleeve frame 4 to the matching block 401, and is symmetrically arranged.

[0077] With this design, when the rubber sleeve 2 is subjected to external forces (such as lateral forces generated when the vehicle turns or passes over bumpy roads, etc.) and tends to rotate relative to the rubber sleeve frame 4, the limit block 403 embedded in the rubber sleeve 2 will play a role. Since the limit block 403 is a relatively hard structure compared to the rubber sleeve 2, it will block the rotation of the rubber sleeve 2, limiting the rubber sleeve 2 to rotate only within a certain range or not at all, thereby playing a role in restraining the rotation of the rubber sleeve 2.

[0078] It is understandable that the shape and number of the limit block 403 are not limited to those shown in the figure, and the shape and number can be adjusted accordingly according to design requirements. In addition, it should be noted that in addition to providing both the anti-slip portion and the limit portion between the rubber sleeve 2 and the rubber sleeve frame 4, only the anti-slip portion or only the limit portion can be provided between the two.

[0079] The vehicle-use limiting rubber sleeve of this embodiment, by adopting the above structure, can not only shorten the protruding distance of the rubber sleeve skeleton 4, but also increase its protruding distance, and can be used for limiting different distances between different products. When the product changes or the distance changes, there is no need to re-open the mold, which can reduce the production cost. In addition, after the rubber sleeve 2 ages, the protruding distance can also be adjusted to ensure its limiting effect. Moreover, when adjusting, the anti-rotation block 3 is driven away from the matching block 401 by the operating handle 302, so that the first ratchet unit 301 and the second ratchet unit 4011 are disengaged, and then the rubber sleeve skeleton 4 is rotated to adjust its protruding distance. The operation is simple and convenient for improving the adjustment efficiency.
