Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness fixing brackets, and in particular relates to a multi-wire harness synchronous fixing bracket. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. The wiring harness refers to a component that is formed by crimping the contact terminals made of copper materials with wires and cables, and then plasticizing the insulator or adding a metal shell on the outside to form a connecting circuit. The automotive wiring harness is generally set in various places in the car body and plays different roles. The existing wire harness fixing bracket can only limit the position of a single wire. When there are many lines at the same position, multiple wire harness fixing brackets are required, which makes fixing inconvenient.

[0003] In the prior art, a multi-wiring harness synchronous fixed automobile wiring harness fixing bracket with patent announcement number CN217753684U is disclosed. The above patent can make the limit rod and the fixing rod move away from each other by pulling the pull ring, and loosen the pull ring. Under the elastic force of the spring, the limit rod and the fixing rod are brought close to each other, so that the wiring harness can be fixed inside the limit rod, thereby facilitating the installation of the wiring harness. Since multiple wiring harnesses can be fixed on the outside of the fixing rod, it is ensured that when there are more wiring harnesses at the same position, multiple wiring harness fixing brackets do not need to be used, so that multiple fixing brackets do not need to be connected to the automobile respectively, which facilitates the installation of the wiring harness.

[0004] The above patent mainly utilizes a limit rod to clamp the wiring harness, but in reality, the space inside the limit rod is fixed, so that only a single-sized wiring harness can be fixed inside the limit rod. Its actual use has great limitations. Once the size of the wiring harness to be used is too small, the limit rod will not firmly fix the wiring harness, which will affect the use effect.

[0005] Therefore, a multi-wire harness synchronous fixing bracket is needed to solve the problem in the prior art that the space inside the limit rod is fixed, so that only a single-sized wire harness can be fixed inside the limit rod. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] See also Figure 1-4 The utility model provides a multi-wire harness synchronous fixed type fixing bracket, comprising a fixed shaft 2, a bearing frame 1 fixed to both ends of the fixed shaft 2, a fixing ring 3 sleeved on the outside of the fixed shaft 2, and a plurality of bearing rods 4 with cavities inside fixed between the fixed shaft 2 and the fixing ring 3, and a wire fixing mechanism for fastening the wire harness is arranged on the bearing rod 4;

[0025] The line fixing mechanism includes a movable sheet 7 slidably arranged on the inner side of the supporting rod 4 and a movable rod 5 vertically fixed on one side of the movable sheet 7, and the movable rod 5 movably passes through the fixed ring 3, and L-shaped limiting rods 6 are fixed on both sides of the movable rod 5, and the other end of the limiting rod 6 is in contact with the fixed ring 3.

[0026] A return spring 8 is fixed to the other side of the movable sheet 7, and the end of the return spring 8 is fixedly connected to the inner wall of the innermost side of the bearing rod 4;

[0027] When in use, the movable rod 5 can be pulled up in advance so that the movable rod 5 drives the movable sheet 7 to slide on the inner side of the load-bearing rod 4 and stretch the reset spring 8 to deform, and while the movable rod 5 moves, the movable rod 5 can drive the two limiting rods 6 to move away from the fixed ring 3, thereby expanding the distance between the limiting rod 6 and the fixed ring 3, making it convenient to manually place the wiring harness under the limiting rod 6 so that the wiring harness contacts the movable rod 5. Then, release the pull on the movable rod 5, and the movable sheet 7 can carry the limiting rod 6 to actively reset the sliding movable rod 5 under the action of the rebound force of the reset spring 8, and the limiting rod 6 can effectively clamp and fix the wiring harness, so that the wiring harness is fastened to the inner side of the limiting rod 6.

[0028] However, from a practical point of view, the space inside the limiting rod 6 is fixed, so that only a single-sized wire harness can be fixed inside the limiting rod 6, and its actual use has great limitations. Once the size of the wire harness to be used is too small, the limiting rod 6 will not be able to fix the wire harness firmly.

[0029] In view of this, if Figure 2 and Figure 3 As shown, the limiting rod 6 is provided with an enhancement component for enhancing the applicable range of the limiting rod 6;

[0030] The efficiency enhancement component includes a contraction groove 9 provided on the inner wall of the limiting rod 6, a pressure plate 10 slidably disposed in the contraction groove 9, a control cover 11 rotatably disposed on the side wall of the limiting rod 6 with a cavity inside, and a control component disposed in the control cover 11 for pushing and pulling the pressure plate 10;

[0031] Through the setting of the enhancement component, if the size of the wiring harness to be used is too small and the wiring harness does not fit the internal space of the limiting rod 6, the personnel can use the regulating component in the enhancement component to push the pressure plate 10 after the limiting rod 6 clamps the wiring harness, so that the pressure plate 10 extends from the inside of the contraction groove 9 to the inside of the limiting rod 6 until the pressure plate 10 presses against the wiring harness, and then the wiring harness can be pressurized from the inside of the limiting rod 6, so that the wiring harness is fixed between the pressure plate 10 and the movable rod 5, thereby further enhancing the application range of the limiting rod 6 and improving the practicality of the device.

[0032] Furthermore, if Figure 3 As shown, the regulating assembly includes a push-pull screw 12 symmetrically and vertically rotatably arranged on the side of the pressure plate 10 away from the movable rod 5 and an inner gear plate 13 fixed on the inner wall of the control cover 11. The end of the push-pull screw 12 is threadedly inserted into the inner side of the control cover 11 and is fixed with a transmission gear 14, which is meshed with the inner tooth surface of the inner gear plate 13.

[0033] The knob controls the cover 11, that is, controls the inner gear plate 13 to mesh with the transmission gear 14, so as to rotate the push-pull screw 12, and then the push-pull screw 12 can be continuously retracted in the inner side of the contraction groove 9 by the thread structure during the rotation process, and then the pressure plate 10 can be effectively pushed and pulled.

[0034] Furthermore, if Figure 1 and Figure 3 As shown, a fixing block 16 is fixed on the side of the limiting rod 6 facing away from the movable rod 5, and a fixing screw 17 is threaded through the fixing block 16. A plurality of fixing holes 15 adapted to the fixing screw 17 are formed around the barrel of the control cover 11;

[0035] Through the setting of the fixing hole 15 and the fixing screw 17, after completing the knob of the control cover 11, the operator then twists the fixing screw 17 so that the fixing screw 17 passes into the fixing hole 15 corresponding to the barrel of the control cover 11 under the threaded structure, and the control cover 11 can be locked to ensure the fixity of the control cover 11 after rotation.

[0036] Furthermore, if Figure 1 As shown, an anti-skid pad is glued on the outer wall of the control cover 11, and an anti-skid pattern is provided on the anti-skid pad;

[0037] By providing the anti-skid pad, the friction of the person's hand can be increased when the person turns the knob to operate the cover 11, so as to prevent the cover 11 from slipping when the knob is turned.

[0038] Furthermore, if Figure 3 , an elastic member is provided on the outer wall of the teeth of the transmission gear 14, and the elastic member is a rubber pad;

[0039] By providing the rubber pad, when the inner gear plate 13 is meshed with the transmission gear 14 for a long time, the wear between the two can be reduced, thereby increasing the service life of the two.

[0040] In summary: through the setting of the enhancement component, if the size of the wiring harness to be used is too small and the wiring harness is not compatible with the internal space of the limiting rod 6, the personnel can use the regulating component in the enhancement component to push the pressure plate 10 after the limiting rod 6 clamps the wiring harness, so that the pressure plate 10 extends from the shrinkage groove 9 until the pressure plate 10 is pressed against the wiring harness, and then the wiring harness can be pressurized from the inside of the limiting rod 6, so that the wiring harness is fixed between the pressure plate 10 and the movable rod 5, thereby further enhancing the application scope of the limiting rod 6 and improving the practicality of the device. Through the setting of the fixing hole 15 and the fixing screw 17, after completing the knob of the control cover 11, the operator twists the fixing screw 17 so that the fixing screw 17 is inserted into the fixing hole 15 corresponding to the barrel of the control cover 11 under the threaded structure, and the control cover 11 can be locked to ensure the fixity of the control cover 11 after rotation.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the present invention.
