Description

Technical Field

[0001] The utility model relates to the technical field of sealing components, in particular to a rubber sealing component for automobile wiring harnesses. Background Art

[0002] Automobile rubber seals are parts used for sealing in automobiles, mainly made of elastomers. Automobile parts cannot be separated from rubber, so rubber (seal) products are widely used. In addition to the tire rubber products that are most easily seen, a car has many other rubber seal material accessories with different structures, sizes and functions.

[0003] The Chinese utility model patent with the authorization announcement number "CN219472707U" is specifically "a rubber seal for automobile wiring harnesses", wherein the rotating shaft can drive multiple wiring harness cards 2 to approach or move away from wiring harness card 1 at the same time, thereby facilitating the fixing of wiring harnesses with different functions between multiple wiring harness cards 1 and the transmission assembly, and effectively preventing the wiring harnesses from falling off from the inside of the rubber seal body;

[0004] However, the automobile wiring harness seal is installed on the automobile, and the automobile needs to be frequently moved, and will be bumpy and swaying when encountering a rugged road section, which requires the clamped wiring harness to be kept fixed. In order to ensure that the wiring harness clamp that squeezes and fixes the wiring harness does not loosen after clamping the wiring harness, the above device adopts a method of connecting the rotating shaft with the threaded groove to achieve limited fixation. However, combined with the use scenario of the automobile wiring harness seal, the rotating shaft is easy to produce relative reverse rotation with the threaded groove, thereby loosening the rotating shaft, so that the wiring harness clamp that squeezes and fixes the wiring harness no longer squeezes and resists the wiring harness, causing the wiring harness to fall off from the inside of the rubber seal body;

[0005] More importantly, in order to ensure that the rotating shaft and the threaded groove are in a threaded tightening state, the rotating shaft needs to be rotated to the last circle of threads in the threaded groove, which makes the moving distance of each wiring harness card fixed, and thus causes the above-mentioned device to be able to clamp and fix only the wiring harness of a specific model, resulting in a problem of low adaptability. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a rubber seal for an automobile wiring harness, which can effectively solve the problems raised in the background technology.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The utility model provides a rubber seal for an automotive wire harness, which includes a sealing ring. Clamping cavities are penetrated and formed at both ends of the sealing ring. A plurality of fixed clamping strips are installed on the inner cavity wall of the clamping cavity. A hexagonal cylinder is arranged at the center of the clamping cavity. A circular groove is formed at one end of the hexagonal cylinder. A plurality of clamping grooves are formed on the inner groove wall of the circular groove and are distributed in an equidistant circumferential array. The telescopic assembly includes a piston rod that telescopically slides through and extends outside the hexagonal cylinder. One end of the piston rod penetrates and extends out of the hexagonal cylinder and is respectively installed with movable clamping strips. The telescopic clamping assembly further includes a hexagonal sleeve rotatably installed in the hexagonal cylinder. Connecting pieces are rotatably connected between the hexagonal sleeve and the corresponding piston rods. The limiting assembly includes a square rod elastically installed at one end of the hexagonal sleeve and slidably penetrating through the circular groove. A round block adapted to be inserted into the circular groove is installed at the end of the square rod. Clamping blocks are installed on the outer ring wall of the round block and are respectively inserted into the corresponding clamping grooves.

[0009] Further, a plurality of equally spaced baffles are installed between the inner cavity wall of the clamping cavity and the hexagonal cylinder. The plurality of baffles cooperate with the hexagonal cylinder to divide the clamping cavity into a plurality of clamping channels with the same space. A fixed clamping strip and a movable clamping strip facing each other are arranged in each clamping channel.

[0010] Further, a limiting hole is penetrated and formed in the inner cavity of the hexagonal cylinder at the bottom of the circular groove. A limiting member is rotatably installed in the limiting hole in a matching manner. Square holes for facilitating the telescopic sliding of the square rod are penetrated and formed on both sides of the limiting member.

[0011] Further, a plurality of piston holes for facilitating the telescopic sliding of the corresponding piston rods are penetrated and formed in the outer wall of the inner cavity of the hexagonal cylinder.

[0012] Further, a square groove is formed at one end of the hexagonal sleeve close to the square rod. A spring is installed between the bottom of the square groove and the square rod. Air inlet and exhaust holes are penetrated and formed in the outer wall of the inner cavity of the hexagonal sleeve.

[0013] Further, a handle is installed on the side of the round block away from the square rod.

[0014] The technical solution provided by the utility model has the following beneficial effects compared with the known prior art:

[0015] The rotation of the hexagonal sleeve is adopted to drive the telescopic sliding of a number of piston rods, and then synchronously drive a number of movable clamping strips to move towards the corresponding fixed clamping strips, so as to clamp and fix the wire harness arranged between the movable clamping strip and the fixed clamping strip. One end of the hexagonal sleeve is telescopically and slidably installed with a square rod, one end of the square rod is installed with a round block, and a number of clamping blocks are installed on the outer ring wall of the round block. The round block is stuck in the round groove at one end of the hexagonal cylinder, and the clamping block is stuck in the clamping groove on the inner ring wall of the corresponding round groove. Through the mutual clamping of the clamping block and the clamping groove, the rotated hexagonal sleeve can be limited and fixed, and the wire harness rubber ring will not loosen and fall off due to the bumping of the vehicle. At the same time, it is also convenient for the hexagonal sleeve to rotate to any position, that is, it is convenient to adjust the distance between the fixed clamping strip and the corresponding movable clamping strip, so as to clamp and fix wire harnesses of different models, and has the advantage of high adaptability.

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model is further described below in conjunction with embodiments.

[0028] Example 1

[0029] Reference Figures 1-5 , which is the first embodiment of the utility model, discloses a rubber seal for automobile wiring harness, including a sealing ring 1, a clamping cavity is formed through both ends of the sealing ring 1, a plurality of fixed clamping strips 11 are installed on the inner cavity wall of the clamping cavity, a hexagonal cylinder 2 is arranged at the center of the clamping cavity 1, a circular groove 21 is formed at one end of the hexagonal cylinder 2, a plurality of clamping grooves 22 distributed in a circular array with equal spacing are formed on the inner groove wall of the circular groove 21, a telescopic assembly includes a piston rod 32 that is telescopically slidable and extends through the outside of the hexagonal cylinder 2, one end of the piston rod 32 extends through the hexagonal cylinder 2, and movable clamping strips 31 are installed respectively, and the telescopic clamping assembly also includes a hexagonal sleeve 33 that is rotatably installed in the hexagonal cylinder 2, and the hexagonal sleeve 33 is installed with a limited position at one end away from the square rod 35. Block, and a limiting groove matched with the limiting block is opened in the inner cavity of the hexagonal cylinder 2. Through the limiting rotation of the limiting block and the limiting groove, the hexagonal sleeve 33 can only rotate in the hexagonal cylinder 2 and cannot be telescopically slid. Therefore, when the square rod 35 telescopes and slides, the hexagonal sleeve 33 remains stationary. Only when the square rod 35 rotates, the hexagonal sleeve 33 will be driven to rotate synchronously. The hexagonal sleeve 33 and the corresponding piston rod 32 are rotatably connected to the connecting piece 34. The limiting assembly includes a square rod 35 elastically mounted on one end of the hexagonal sleeve 33 and sliding through the circular groove 21. The end of the square rod 35 is equipped with a round block 37 that is adapted to be snapped into the circular groove 21, and the outer ring wall of the round block 37 is equipped with blocks 38 that are respectively snapped into the corresponding slots 22.

[0030] Example 2

[0031] Reference Figures 1-5, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a number of equally spaced baffles 12 are installed between the inner cavity wall of the clamping cavity and the hexagonal cylinder 2. The number of baffles 12 cooperates with the hexagonal cylinder 2 to divide the clamping cavity into a number of clamping channels with the same space. A fixed clamping strip 11 and a movable clamping strip 31 facing each other are arranged in each clamping channel. Both the fixed clamping strip 11 and the movable clamping strip 31 are made of rubber and have a certain deformation function. Therefore, this sealing member can clamp and fix multiple wire harnesses with different outer diameter specifications at the same time. A limiting hole is opened through the bottom of the circular groove 21 and into the inner cavity of the hexagonal cylinder 2. A limiting member 23 is rotatably installed in the limiting hole in a matching manner. Square holes for the telescopic sliding of the square rod 35 are opened through both sides of the limiting member 23. The design of the limiting member 23 is to ensure that no foreign objects and impurities enter the hexagonal cylinder 2. A number of piston holes for the telescopic sliding of the corresponding piston rods 32 are opened through the outer wall of the inner cavity of the hexagonal cylinder 2. The piston holes are designed to match the piston rods 32. Therefore, the piston rods 32 can only be telescopic and cannot tilt or shake. A square groove is opened at one end of the hexagonal sleeve 33 close to the square rod 35. A spring 36 is installed between the bottom of the square groove and the square rod 35. Air inlet and outlet holes are opened through the outer wall of the inner cavity of the hexagonal sleeve 33 to maintain the air pressure inside the hexagonal sleeve 33 and ensure that the square rod 35 can smoothly telescopic slide. A handle 39 is installed on the side of the round block 37 away from the square rod 35, which is convenient to pull out the round block 37 from the circular groove 21.

[0032] The remaining structures are the same as those in Embodiment 1.

[0033] The working process of the present utility model is as follows:

[0034] First, the wire harnesses to be clamped and fixed are respectively passed through each clamping channel and arranged between the corresponding fixed clamping strip 11 and movable clamping strip 31. Then, the handle 39 is pulled outwards, so as to pull out the round block 37 from the circular groove 21, and a number of clamping blocks 38 are pulled out from the corresponding clamping grooves 22. The square rod 35 slides telescopically with the hexagonal sleeve 33 and the limiting member 23, and the spring 36 is forced to stretch and deform to obtain an elastic restoring force. At this time, the handle 39 is rotated, thereby driving the round block 37, a number of clamping blocks 38, the square rod 35, the limiting member 23, the spring 36 and the hexagonal sleeve 33 to rotate synchronously;

[0035] Secondly, with the rotation of the hexagonal sleeve 33, since a number of piston rods 32 slide telescopically through the piston holes on the hexagonal cylinder 2, and a connecting piece 34 is rotatably installed between the piston rods 32 and the hexagonal sleeve 33, the corresponding piston rods 32 are pushed to extend outwards in the piston holes through the connecting piece 34, and then the corresponding movable clamping strip 31 is pushed, so that the movable clamping strip 31 gradually approaches the corresponding fixed clamping strip 11 to complete the extrusion and fixation of the wire harness;

[0036] Finally, after the wire harness is fixed, release the lifting handle 39. The square rod 35 is pulled back to its original position by the elastic restoring force generated by the deformation of the spring 36. At the same time, the round block 37 is pulled to be inserted into the round groove 21 again, and several clamping blocks 38 are inserted into the corresponding clamping grooves 22 again. Since the distance between several clamping blocks 38 is the same as the distance between several clamping grooves 22, and several clamping blocks 38 and the corresponding clamping grooves 22 are designed to be adapted to each other, all the clamping blocks 38 can be inserted into the corresponding clamping grooves 22 again after rotation.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the present invention in each embodiment.
