Detailed Description
The present invention will be described in detail with reference to the following preferred embodiments.
As shown in fig. 1-4, the waterproof sealing device for the wall passing of the two-section crawler comprises a connecting disc 1, a sealing inner rubber ring 2, a self-tightening sealing rubber ring 3 and a compression nut 4.
The connecting plate 1 is a hollow tubular structure and can be inserted into an opening on the side wall 6 of the carriage, and a hollow tube of the connecting plate can be penetrated by cables or tubes. One end of the connecting disc 1 inserted into the vehicle compartment side wall 6 is provided with a flange extending radially inward, and the other end is provided with a flange extending radially outward. The flange is in contact with the compartment side wall 6, thereby fixing the connection plate 1 to the compartment side wall 6. Specifically, the connection disc 1 is fixed on the compartment side wall 6 by screws, and a flat rubber pad 5 is provided between the connection disc 1 and the compartment side wall 6. The flat rubber cushion 5 is arranged between the connecting disc 1 and the carriage side wall 6, and can play a role in sealing and loosening prevention after being fixedly pressed by screws, prevent liquid such as water, oil and the like from flowing to the other side from one side of the carriage side wall 6 along the outer wall of the connecting disc 1, and increase the stress area to fasten and strengthen the fixed connection between the connecting disc 1 and the carriage side wall 6.
The connecting disc 1 is a key part for connecting the side wall 6 of the carriage with a cable or a pipe, is made of nickel-aluminum bronze, has the advantages of high mechanical property, high strength, wear resistance, heat resistance, no iron and rock property and the like, has good corrosion resistance in atmosphere, fresh water and seawater, and has good cutting performance and strong seawater corrosion resistance; meets the requirements of corrosion resistance and salt mist resistance of the double-section tracked vehicle.
The inner side of the connecting disc 1 is provided with a self-tightening sealing rubber ring 3, and the inner side of the self-tightening sealing rubber ring 3 is provided with a sealing inner rubber ring 2. The sealing inner rubber ring 2 is in direct contact with the cable or pipe in the connection disc 1. An internal thread is arranged in an opening on one side of the connecting disc 1 with the flange and is used for being in threaded connection with the compression nut 4. The flange on one side of the connecting disc 1 is used for bearing the self-sealing rubber sealing ring 3 and the sealing inner rubber sealing ring 2, and the self-sealing rubber sealing ring 3 and the sealing inner rubber sealing ring 2 are prevented from being separated from the range of the connecting disc 1 when being extruded.
When gland nut 4 was installed in connection pad 1, gland nut 4 can extrude sealed interior rubber ring 2 and sealed rubber ring 3 of self-tightening, played the effect of binding off, and then tightly wrapped up cable or pipe, played sealed effect.
The compression nut 4 is the same as the connecting disc 1, and also adopts nickel-aluminum bronze with high corrosion resistance and strength as a main material, the compression nut 4 is in charge of compressing the self-tightening sealing rubber ring 3 and the sealing inner rubber ring 2 in the connecting disc 1, so that the self-tightening sealing rubber ring 2 extrudes a cable and a pipe in the connecting disc 1, the inside of the connecting disc is closed up, the passing cable (pipe) is wrapped, and a sealing effect is achieved.
As shown in fig. 1-3, the tail portion (the side close to the compression nut 4) of the self-sealing rubber ring 3 has a spiral structure, an inclination angle of 5 degrees and a rounded design of side wall, and can be radially and inwardly extruded when being axially extruded. The head of the self-tightening rubber sealing ring 3 is provided with a V-shaped groove, the opening end of the V-shaped groove faces the end face of the head of the self-tightening rubber sealing ring 3, and the V-shaped grooves are uniformly distributed on the annular end face of the head of the self-tightening rubber sealing ring 3.
When 3 cooperation of self-tightening rubber sealing ring seal interior rubber ring 2 use, by gland nut 4 and connection pad 1 extrusion back, tighten together, do the design of closing up, tightly wrap up the inside cable or the pipe of connection pad 1, especially set up the V-arrangement groove structure, self-tightening rubber sealing ring 3 head one end by the extrusion back, the V-arrangement groove is compressed tightly and is merged together, extrudees inseparabler. Unlike metal extrusion, the better elasticity of the self-tightening sealant ring 3 and the sealant inner ring 2 makes the inner cable or tube insufficient to reduce flow by being extruded.
The flat rubber pad 5, the self-tightening sealing rubber ring 3 and the sealing inner rubber ring 2 are all made of silicon rubber, and the silicon rubber has excellent heat resistance and low temperature resistance and has ozone resistance and weather resistance; the silicon rubber can keep the service performance and various advantages within the range of-70-160 ℃, so the silicon rubber is often used in occasions such as a thermalization structure, a sealing lining ring under a strong light source, a valve pad and the like, and is suitable for the requirement of the service environment of the double-section tracked vehicle.
When the waterproof sealing device for the wall passing of the two-section crawler is used, the connecting disc 1 is firstly installed on the side wall 6 of the carriage by using screws, and then a cable or a pipe penetrates through the connecting disc 1; and the compression nut 4 is screwed on the connecting disc 1 to extrude the self-tightening sealing rubber ring 3 and the sealing inner rubber ring 2, so that a sealing structure is realized.
The inventive concept is explained in detail herein using specific examples, which are given only to aid in understanding the core concepts of the invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are included in the scope of the present invention.
