Abstract

The utility model relates to an automobile rake inhaul cable connector device which comprises a steel wire rope, wherein the steel wire rope penetrates through a sleeve pipe, and a pull force head is connected with the end portion of the steel wire rope. The automobile rake inhaul cable connector device is characterized in that the end portion of the sleeve pipe is connected with one end of a pipe connector, and the other end of the pipe connector is provided with two steps. The diameter of the first step is smaller than that of the second step, and the second step is provided with a boss corresponding to the peripheral direction of the first step. The end portion of the first step is fixed with an expansion fastening piece through an installation spigot, and a rubber ring is arranged between the expansion fastening piece and the end face of the second step. The expansion fastening piece comprises a sleeve body and expansion wings, wherein the sleeve body is provided with an open groove, and the expansion wings are evenly distributed on the outer surface of the sleeve body. one ends, far away from the pipe connector, of the expansion wings are fixedly connected with the sleeve body, and an expansion gap is formed between one ends, close to the pipe connector, of the expansion wings and the sleeve body. The automobile rake inhaul cable connector device plays a role of tightening, and simultaneously also can reduce noise and vibration, and well protects an inhaul cable.

Description

Braking automobile cable connector device

Technical field

The utility model relates to a kind of braking automobile cable connector device, especially a kind of automobile hand brake brake line piecing devices.

Background technique

At present, general automobile hand brake brake line joint all is to have the barrel joint that a metal clamps is installed at one, during attachment hole, fixes with metal clamps or nut inside and outside drag-line passes operator cabin.The major defect that the cable connector of this structure exists is: trouble is installed, and fixing unreliable, the metal impact friction produces noise, and nut of long duration or metal clamps all easily are out of shape even are damaged the very big like this rate of fault that increases drag-line.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of braking automobile cable connector device is provided, when playing the role of fastening, can also the noise abatement damping, and protect preferably drag-line.

According to the technological scheme that the utility model provides, described braking automobile cable connector device comprises wire rope, and the steel wire penetrating sleeve pipe connects the pulling force head in the end of wire rope; It is characterized in that: the end of described sleeve pipe is connected with an end of pipe joint, and the other end of pipe joint is provided with the two-stage step, and the diameter of first order step is less than the diameter of second level step, and second level step forms boss with respect to the circumferencial direction of first order step; The end of described first order step arranges rubber ring by seam fixed expansion fastening piece is installed between the end face of expansion fastener and second level step.

Described expansion fastener comprises the body that is provided with opening slot and is evenly distributed on the expansible wings of cover external surface; Described expansible wings is fixedly connected with body away from an end of pipe joint, forms expansion space between an end of the close pipe joint of expansible wings and the body.

Braking automobile cable connector device described in the utility model can also the noise abatement damping when playing the role of fastening, and protects preferably drag-line.

Embodiment

The utility model is described in further detail below in conjunction with concrete accompanying drawing.

Such as Fig. 1 ~ shown in Figure 4: as described in braking automobile cable connector device comprise pulling force head 1, wire rope 2, expansion fastener 3, rubber ring 4, pipe joint 5, sleeve pipe 6, first order step 7, second level step 8, body 31, expansible wings 32, opening slot 33 etc.

As shown in Figure 1, the utility model comprises wire rope 2, and wire rope 2 passes sleeve pipe 6, connects pulling force head 1 in the end of wire rope 2; The end of described sleeve pipe 6 is connected with an end of pipe joint 5, and the other end of pipe joint 5 is provided with the two-stage step, and the diameter of first order step 7 is less than the diameter of second level step 8, and second level step 8 forms boss with respect to the circumferencial direction of first order step 7; The end of described first order step 7 arranges rubber ring 4 by seam fixed expansion fastening piece 3 is installed between the end face of expansion fastener 3 and second level step 8;

Such as Fig. 2 ~ shown in Figure 4, described expansion fastener 3 comprises the body 31 that is provided with opening slot 33 and the expansible wings 32 that is evenly distributed on body 31 outer surfaces, described expansible wings 32 is fixedly connected with body 31 away from an end of pipe joint 5, forms expansion space between an end of expansible wings 32 close pipe joints 5 and the body 31;

The material of described expansion fastener 3 is 65Mn, has good elasticity and wear resistance.

Rubber ring 4 described in the utility model can play and prevent that expansion fastener 3 from becoming flexible and the effect of buffering axial friction, reduces and shakes, reduces simultaneously noise; Inside and outside drag-line passes operator cabin during attachment hole, expansion fastener 3 is squeezed and passes attachment hole, pass after the attachment hole the at once resilience of expansible wings 32 on the expansion fastener 3 and return original position, attachment hole is stuck between the end face of second level step 8 of expansion fastener 03 and pipe joint 5, reaches fastening effect; At this moment, rubber ring 4 is in the end of second level step 8, have good elasticity because rubber ring 4 itself is soft wear-resisting, the friction vibrations that can the buffer mechanism motion when rubber ring 4 cooperates the inside and outside attachment hole of expansion fasteners 3 fastening operator cabins produce reduce noise.
