Description

Technical Field

[0001] The utility model relates to the technical field of rubber bushings, in particular to automobile rubber bushings. Background Art

[0002] Automobile rubber bushing is an elastic engineering material that can withstand large strains without permanent deformation and fracture. In the automotive industry, rubber bushings are widely used in various shock-absorbing and noise-reducing devices. Durability is a key performance in the development of rubber bushings, because fatigue failure of rubber bushings will seriously affect the handling stability, comfort performance and even safety performance of the car. The axial stiffness of rubber bushings directly affects the handling stability, smoothness, NVH performance and load-bearing deformation performance of the car.

[0003] The utility model patent application document with publication number "CN216343597U" discloses a novel rubber bushing, including a rubber bushing, which is provided with an inner tube, a covering layer, a rubber layer and an outer jacket layer from the inside to the outside, the inner tube is a metal tube, and the metal tube, the covering layer, the rubber layer and the outer jacket layer are integrally formed; the rubber bushing of the utility model is both lightweight and has a certain strength, shortens the production process, improves production efficiency, reduces costs, and is suitable for rubber bushings.

[0004] The new rubber bushing disclosed in the above document has the following defects: the rubber ring of this technical solution will stick to the inner tube when used for a long time, resulting in a relatively high overall replacement cost, and the inner tube of this technical solution is not provided with an anti-slip layer, which may cause the rubber ring to slide and fall off.

[0005] It can be seen from this that the existing new rubber bushing does not have a disassembly structure, and it is necessary to improve the existing deficiencies and provide an automotive rubber bushing. Utility Model Content

[0006] The purpose of the utility model is to provide an automobile rubber bushing to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a rubber bushing for automobiles, comprising an inner metal tube, the upper surface of the inner metal tube is provided with a first threaded hole, the number of the first threaded holes is fixed to four, a disassembly structure is movably mounted on the peripheral side surface of the inner metal tube, the disassembly structure comprises a sleeve, an anti-skid ring, a second threaded hole, a placement groove, anti-skid stripes and screws, a sleeve is movably mounted on the peripheral side surface of the inner metal tube, an anti-skid ring is fixedly mounted on the peripheral side surface of the sleeve, a second threaded hole is provided on the upper surface of the sleeve, the number of the second threaded holes is fixed to four, the second threaded hole is communicated with the first threaded hole, a placement groove is provided on the upper surface of the second threaded hole, a plurality of anti-skid stripes are provided on the inner bottom of the placement groove, a screw is threadedly connected to the internal thread of the second threaded hole, and the screw is threadedly connected to the first threaded hole.

[0009] Furthermore, a rubber ring is fixedly mounted on the peripheral side surface of the casing.

[0010] Furthermore, an outer metal tube is fixedly mounted on the peripheral side of the rubber ring.

[0011] Furthermore, the inner wall of the inner metal tube is provided with grooves, and the number of the grooves is fixed at two.

[0012] Furthermore, a plurality of springs are fixedly installed inside the grooves, and a pressing block is fixedly installed at one end of the spring.

[0013] Furthermore, a smooth surface is provided on one side of the pressing block, and an anti-slip surface is provided on the other side of the pressing block.

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

[0015] (1) The utility model is implemented by sleeve-connecting the sleeve to the outer surface of the inner metal tube, and then fixing the inner metal tube and the sleeve by screwing screws into the second threaded hole and the first threaded hole. The anti-skid stripes are provided to prevent the screws from falling off. Then, the rubber ring and the outer metal tube are installed one by one. The anti-skid ring fits the rubber ring to increase friction and prevent the rubber ring from sliding off. After long-term use, the rubber ring will stick to the outer surface of the sleeve. The screws can be removed to replace it separately, thereby reducing the use cost.

[0016] (2) The utility model sleeves the inner metal tube onto the external connecting piece by means of the arrangement of the spring, the pressing block, the smooth surface and the anti-slip surface, and then uses the smooth surface to squeeze the spring into the interior of the groove. After the installation is completed, the anti-slip surface increases the friction against the spring to prevent the inner metal tube from moving back, thereby increasing the tightness of the connection and improving the usability.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
