Description

Technical Field

[0001] This utility model relates to the field of bushing processing, and in particular to a tear-resistant and shock-absorbing bushing. Background Technology

[0002] A bushing is an accessory used on the outside of mechanical parts to achieve functions such as sealing and wear protection. It refers to a bushing that acts as a gasket. In the field of valve applications, the bushing is inside the valve cover and is generally made of corrosion-resistant materials such as polytetrafluoroethylene or graphite for sealing purposes.

[0003] With the frequent use of various mechanical devices and vehicles, the stress, impact, and other complex operating conditions they endure are constantly increasing. Existing ordinary shock absorber bushings often lack the structure and materials to effectively withstand these high-intensity external forces, and the rubber outer layer is highly prone to tearing. Once tearing occurs, not only will the bushing's shock absorption function be significantly reduced, but it may also lead to abnormal wear and loosening of related components in the entire equipment or vehicle, thereby affecting the normal operation of the equipment and even posing potential risks to the safety of users.

[0004] The above-mentioned device has the following drawbacks: existing bushings either lead to a significant increase in cost due to improvement measures, which limits the product's market promotion, or they sacrifice a certain amount of shock absorption effect while improving tear resistance, thus failing to meet actual needs. Therefore, a tear-resistant and shock-absorbing bushing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a tear-resistant and shock-absorbing bushing, which aims to improve the problem of insufficient tear resistance and seismic strength of bushings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tear-resistant and shock-absorbing bushing, comprising a sleeve body, a sleeve base fixedly connected to the bottom end of the outer wall of the sleeve body, a fixing groove formed on the upper surface of the sleeve base, multiple sets of evenly distributed gaskets fixedly installed in the inner wall of the sleeve body, a tear-resistant component provided on the upper surface of the sleeve base, an auxiliary component provided on the upper surface of the sleeve body, the tear-resistant component comprising a support ring, multiple sets of evenly distributed positioning plates fixedly connected to the upper surface of the support ring, a rubber strip fixedly installed on the outer wall of the positioning plate, and a limit groove formed on the rear surface of the positioning plate.

[0007] As a further description of the above technical solution: the auxiliary component includes an auxiliary disk, a rubber pad is fixedly installed on the upper surface of the auxiliary disk, and multiple sets of evenly distributed protrusions are formed on the upper surface of the rubber pad. Two sets of positioning blocks are fixedly connected to both the left and right ends of the auxiliary disk, and fixing bolts are detachably connected to the inner wall of the positioning blocks.

[0008] As a further description of the above technical solution: an installation post is provided between the groove and the limiting groove on the outer wall of the sleeve.

[0009] As a further description of the above technical solution: the support ring is elastically connected to the inner wall of the fixing groove by an elastic element.

[0010] As a further description of the above technical solution: the top end of the elastic element is fixedly installed on the lower surface of the support ring, and the bottom end of the elastic element is fixedly installed in the inner wall of the fixing groove.

[0011] As a further description of the above technical solution: the outer surface of the protrusion is configured as a trapezoidal structure, and the top corner of the protrusion is configured as a rounded corner structure.

[0012] As a further description of the above technical solution: the positioning block is fixedly installed in the groove on the upper surface of the positioning plate by fixing bolts.

[0013] As a further description of the above technical solution: the auxiliary disk is detachably connected to the groove on the upper surface of the sleeve.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the support ring, positioning plate, rubber strip and other components in the tear-resistant assembly cooperate with each other through the connection relationship to achieve the shock absorption effect of the equipment.

[0016] 2. In this utility model, the auxiliary components such as the auxiliary disk, positioning block, and protrusion block in the auxiliary assembly cooperate with each other through the connection relationship. The V-shaped arrangement of the protrusion blocks with their side walls close to each other improves the shock resistance of the equipment. The positioning block and fixing bolts provide simple positioning for the auxiliary components, which improves the convenience of equipment installation and disassembly and enriches the functionality of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a tear-resistant and shock-absorbing bushing, comprising a sleeve body 1, which provides protection, positioning, and wrapping for the equipment. A sleeve base 2 is fixedly connected to the bottom of the outer wall of the sleeve body 1, which provides support for the equipment. A fixing groove 21 is provided on the upper surface of the sleeve base 2, through which the equipment supports the tear-resistant component 3. Multiple sets of evenly distributed gaskets 5 are fixedly installed in the inner wall of the sleeve body 1. The friction of the gaskets 5 against the outer wall of the output shaft is increased, preventing the sleeve body 1 from falling off and improving the anti-fall-off performance of the sleeve body 1. The upper surface of the sleeve base 2 is provided with the tear-resistant component 3, and the upper surface of the sleeve body 1 is provided with the auxiliary component 4.

[0025] Reference Figure 1 - Figure 3When the sleeve 1 cracks due to compression during operation, the tear-resistant component 3 activates. When the tear-resistant component 3 includes the support ring 31, and an external impact force comes from the vertical direction, the impact force acts on the positioning plate 32. The compressive force of the positioning plate 32 drives the support ring 31 downwards. The support ring 31 is elastically connected to the inner wall of the fixing groove 21 via an elastic element 34. The top end of the elastic element 34 is fixedly installed on the lower surface of the support ring 31, and the bottom end of the elastic element 34 is fixedly installed in the inner wall of the fixing groove 21. Multiple sets of evenly distributed positioning plates 32 are fixedly connected to the upper surface of the support ring 31, exerting a compressive force on the elastic element 34, causing the elastic element 34 to generate elastic force. The force exerted is combined to reduce the impact on the support ring 31, thereby achieving the shock absorption effect on the equipment. A rubber strip 33 is fixedly installed on the outer wall of the positioning plate 32. When tearing stress occurs inside the sleeve 1, the mounting post 36 works with the positioning plate 32 to wrap the outer wall of the sleeve 1. A limit groove 35 is opened on the rear surface of the positioning plate 32. When the rubber strip 33 wraps, the stress distributed on the positioning plate 32 is spread out, which further improves the wrapping strength of the sleeve 1. The mounting post 36 is set between the groove and the limit groove 35 on the outer wall of the sleeve 1 to prevent the outer wall of the sleeve 1 from tearing due to excessive stress at a certain point, thereby improving the tear resistance of the equipment.

[0026] Reference Figure 2 - Figure 4When the equipment vibrates, the auxiliary component 4 activates. The auxiliary component 4 includes an auxiliary disk 41, which is detachably connected to a groove on the upper surface of the sleeve 1. A rubber pad 44 is fixedly installed on the upper surface of the auxiliary disk 41. Through the setting of the protrusions 45, the compression deformation caused by vibration is deformed through the convex surface of the protrusions 45, so that the sidewalls of two adjacent second protrusions 45 form a shock-absorbing groove. Multiple sets of evenly distributed protrusions 45 are opened on the upper surface of the rubber pad 44. The sidewalls of two adjacent second protrusions 45 are arranged in a V-shape, that is, the shape of the shock-absorbing groove is V-shaped. The first protrusion 45 extends radially along the shock-absorbing auxiliary disk 41. The outer surface of the protrusion 45 is set as a trapezoidal structure, and the top corner of the protrusion 45 is set as a rounded corner structure. The cross-section of the first protrusion 45 in the axial direction of the auxiliary component 4 is trapezoidal, and the size of the first protrusion 45 is radially closer to the mounting auxiliary disk 41. As the auxiliary plate 41 gradually decreases in size, the first protrusion 45 extends radially along the auxiliary component 4, allowing the first shock-absorbing structure to cover the end face of the first protrusion 45. This achieves a good shock absorption effect through the first protrusion 45. Since the end face of the auxiliary component 4 generally needs to bear a large pressure, the shape of the first protrusion 45 is set as a trapezoid to strengthen the contact between the end face and other structures, thereby improving the vibration resistance of the equipment. Two sets of positioning blocks 42 are fixedly connected to both the left and right ends of the auxiliary plate 41. The auxiliary plate 41 supports the rubber pad 44. The positioning blocks 42 are fixedly installed in the groove on the upper surface of the positioning plate 32 by fixing bolts 43. Fixing bolts 43 are detachably connected to the inner wall of the positioning blocks 42. The positioning blocks 42, in conjunction with the fixing bolts 43, perform a simple positioning function for the auxiliary component 4, improving the convenience of equipment installation and disassembly and enriching the functionality of the equipment.

[0027] Working principle: When the sleeve 1 cracks due to compression during operation, the tear-resistant component 3 activates. When the external impact force comes from the vertical direction, it acts on the positioning plate 32. The compression force of the positioning plate 32 drives the support ring 31 to move downward, which compresses the elastic element 34, causing the elastic element 34 to generate a reaction force. This combines the impact force on the support ring 31, achieving the shock absorption effect on the equipment. When tearing stress occurs inside the sleeve 1, the mounting column 36, in conjunction with the positioning plate 32, wraps the outer wall of the sleeve 1. The stress distributed on the positioning plate 32 is spread out through the wrapping action of the rubber strip 33, further improving the wrapping strength of the sleeve 1 and preventing the outer wall of the sleeve 1 from tearing due to excessive stress at a certain point, thus improving the tear resistance of the equipment.

[0028] When the equipment vibrates, the auxiliary component 4 activates. Through the arrangement of the protrusions 45, the compression deformation caused by the vibration is amplified by the convex surface of the protrusions 45, causing the sidewalls of two adjacent second protrusions 45 to form a damping groove. The sidewalls of two adjacent second protrusions 45 are arranged in a V-shape, i.e., the damping groove is V-shaped. The first protrusion 45 extends radially along the damping auxiliary disk 41. The cross-section of the first protrusion 45 in the axial direction of the auxiliary component 4 is trapezoidal, and the size of the first protrusion 45 gradually decreases radially towards the mounting auxiliary disk 41, thus reducing the vibration of the second protrusion 45. When a protrusion 45 extends radially along the auxiliary component 4, the first damping structure can cover the end face of the first protrusion 45, thereby achieving a good damping effect through the first protrusion 45. The end face of the auxiliary component 4 generally needs to bear a large pressure, so the shape of the first protrusion 45 is set as trapezoidal to strengthen the contact between the end face and other structures. The rubber pad 44 is supported by the auxiliary disk 41, and the auxiliary component 4 is simply positioned by the positioning block 42 in conjunction with the fixing bolt 43, which improves the convenience of equipment installation and disassembly and enriches the functionality of the equipment.
