Description
Technical Field
[0001] The utility model relates to the technical field of rubber products, in particular to a high temperature resistant rubber product. Background Art
[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber products refer to the activities of producing various rubber products with natural and synthetic rubber as raw materials, and also include rubber products recycled from waste rubber. Rubber products are widely used in various aspects of industry or life, among which rubber casing is a very common one. The inner layer of the rubber hose is the part that carries the medium, generally made of natural rubber, synthetic rubber and other materials. The hose made of natural rubber has good acid and alkali resistance and wear resistance, and is suitable for conveying water, air, oil media, etc., while the hose made of synthetic rubber is resistant to high temperature and corrosion, and is suitable for conveying chemical media, oil media, etc.
[0003] The existing rubber hose has poor protection due to the texture of rubber itself, and its high temperature resistance and heat insulation performance need to be improved; when the shell of the existing rubber hose is damaged, it can only be replaced as a whole, which is relatively wasteful. Therefore, a high temperature resistant rubber product is proposed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a high temperature resistant rubber product to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A high temperature resistant rubber product comprises a synthetic rubber layer, wherein the outer side of the synthetic rubber layer is fixedly connected to a heat insulating layer, the outer side of the heat insulating layer is fixedly connected to a natural rubber layer, a fixing hole is provided on the surface of the natural rubber layer, a fixing rod is snap-connected to the inner side of the fixing hole, a connecting layer is fixedly connected to the outer side of the fixing rod, a composite heat insulating reinforcement layer is fixedly connected to the outer side of the connecting layer, a first limiting groove is provided at one end of the composite heat insulating reinforcement layer located above, a limiting block is fixedly connected to one end of the composite heat insulating reinforcement layer located below, a snap-fit groove is symmetrically provided at the inner side of the first limiting groove, a clamping block is snap-connected inside the snap-fit groove, one end of the clamping block is fixedly connected to a connecting rod, an end of the connecting rod away from the clamping block is fixedly connected to a limiting plate, a second limiting groove is symmetrically provided at the outer side of the limiting block, and one end of the clamping block is fixedly connected to a second spring located at the outer side of the connecting rod.
[0007] Preferably, a first spring is fixedly connected to the outer side of the composite heat-insulating reinforcement layer, and one end of the first spring away from the composite heat-insulating reinforcement layer is fixedly connected to a protective shell.
[0008] Preferably, the second limiting groove is internally slidably connected to a limiting plate and a connecting rod, and the connecting rod, the limiting plate and the second limiting groove form a group, with a total of eight groups, which are symmetrically arranged on the surface of the limiting block.
[0009] Preferably, there are a plurality of first springs, which are evenly arranged between the protective shell and the composite heat-insulating reinforcement layer.
[0010] Preferably, the inner side of the first limiting groove is snap-connected with a limiting block, and the first limiting groove and the limiting block form a group, and there are two groups in total, which are symmetrically arranged at both ends of the composite thermal insulation reinforcement layer.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. In the utility model, the protective shell, the first spring, the composite heat-insulating reinforcement layer and other components are provided. The protective shell can play a supporting and protective role at the outermost periphery of the rubber hose. The first spring can effectively reduce the impact of external impact on the internal rubber hose. The composite heat-insulating reinforcement layer can further improve the heat-insulating and high-temperature-resistant effect of the rubber hose and protect the circuit inside the rubber hose, thereby solving the problem that the existing rubber hose has poor protection due to the texture of the rubber itself and the high-temperature-resistant and heat-insulating performance needs to be improved.
[0013] 2. In the utility model, by setting the composite heat-insulating reinforcement layer, the first limiting groove, the engaging groove, the clamping block, the connecting rod, the limiting plate, the second limiting groove, the second spring and the limiting block and other components, firstly align the fixing rod with the fixing hole and engage it, and when the fixing rod engages with the fixing hole, the limiting block will also engage with the first limiting groove. Before the limiting block enters the first limiting groove, it is necessary to press the clamping block by hand, compress the second spring through the clamping block, and press the connecting rod into the second limiting groove, and then squeeze the two composite heat-insulating reinforcement layers to make the limiting block and the first limiting groove completely engage, and when the limiting block engages with the first limiting groove, the clamping block pops open under the action of the second spring, so that the clamping block is engaged in the engaging groove, and the limiting plate can prevent the connecting rod from falling off from the second limiting groove. The provided card block and the engaging groove can effectively prevent the limit block from falling off from the first limit groove, so that the composite heat insulation reinforcement layer, the protective shell and the connecting layer are firmly fixed together and fixed on the surface of the rubber hose. The fixing rod can prevent the protective shell from rotating and falling off. When the protective shell is damaged, it is only necessary to separate the composite heat insulation reinforcement layer with force. Under the action of external force, the limit block is pulled out of the first limit groove. The special curvature of the engaging groove and the card block will drive the card block to slide out of the engaging groove when the limit block moves downward, and the engaging block will drive the connecting rod to enter the second limit groove. After that, the protective shell and the composite heat insulation reinforcement layer and other components can be easily separated and removed, thereby solving the problem that the existing rubber hose can only be replaced as a whole when the shell is damaged, which is relatively wasteful.

[0022] A first spring 8 is fixedly connected to the outer side of the composite thermal insulation strengthening layer 7, and one end of the first spring 8 away from the composite thermal insulation strengthening layer 7 is fixedly connected to the protective shell 9. The interior of the second limit groove 15 is slidably connected to the limit plate 14 and the connecting rod 13, and the connecting rod 13, the limit plate 14 and the second limit groove 15 are a group, with a total of eight groups, which are symmetrically arranged on the surface of the limit block 17. There are several first springs 8, and they are evenly arranged between the protective shell 9 and the composite thermal insulation strengthening layer 7. The inner side of the first limit groove 10 is snap-fitted and connected to the limit block 17, and the first limit groove 10 and the limit block 17 are a group, with a total of two groups, which are symmetrically arranged at both ends of the composite thermal insulation strengthening layer 7.
[0023] Working process: when it is necessary to use high temperature resistant rubber products, first align the fixing rod 5 with the fixing hole 4 and snap it in. When the fixing rod 5 is snapped into the fixing hole 4, the limiting block 17 will also be snapped into the first limiting groove 10. Before the limiting block 17 enters the first limiting groove 10, it is necessary to press the clamping block 12 by hand, compress the second spring 16 through the clamping block 12, and press the connecting rod 13 into the second limiting groove 15, and then squeeze the two composite thermal insulation reinforcement layers 7 to make the limiting block 17 and the first limiting groove 10 completely snap together.
