Abstract

The utility model discloses an adjustable bush with a structure that a bush body contains an opening, and the top thereof is provided with a head joint. The bush body surface under the head joint is provided with a ring of stopping retrograded boss cooperating with a frame seat inner cavity groove, under which is provided with a concave object corresponding with six vertical convex guidance glutens back of the inner wall thereof; the bush body of the adjustable bush is in a cone shape with inclination, and the inclination thereof is corresponding with the inclination of the stent seat inner cavity. The inner wall shape of the bush body is characterized in that the back of the inner cavity in the stopping retrograded boss surface is provided with a coil of groove corresponding with the stopping retrograded boss, under which is provided with six vertical convex guidance glutens, and the radial dimension thereof is equal to that of the inner cavity at the top of the groove. The present model is equipped between a fastening rail tube and a specialized stent seat at the bus to efficiently and conveniently eliminate the gap and realize the stable combination of the fastening rail and the specialized stent seat, also the utility model has a role of decoration.

Description

Adjustable buss

Technical field

The utility model relates to the fixed armrest in the public transit vehicle, refers in particular to a kind of between fixed armrest pipe and adjustable buss between bracket is connected.

Technical background

The structure that fixed armrest pipe in the existing public transit vehicle is connected with bracket sees also Fig. 1, and fixed armrest pipe 1 is contained in has certain matching gap to exist in the bracket 2.Public transit vehicle vibration under steam can make fixed armrest pipe 1 and bracket 2 produce collision, sends noise.

Sign the problem in above-mentioned existence, the utility model provides a kind of diameter adjustable lining, is placed between fixed armrest pipe and a kind of special bracket, can eliminate gap and noise easily and effectively, and fixed armrest is combined with special bracket is firm.

Summary of the invention

The purpose of this utility model is achieved in that adjustable buss is plastics or rubber product, supporting a kind of special inner chamber has a groove and a gradient mounting, its structural design is: body band opening, the top has a circle cap head, body appearance below the cap head is provided with the retaining boss that a circle is complementary with the bracket lumen channels, be provided with below the retaining boss with its back inwall on six or N the vertical corresponding concaver of convex surface guiding rib.The body appearance of adjustable buss is the taper of inclination, and its gradient is corresponding with the gradient of this bracket inner chamber.The body inner wall shape of adjustable buss is: be provided with a circle and the corresponding groove of retaining boss on the back inwall at appearance retaining boss place, be provided with six or N vertical convex surface guiding rib below groove, its radial dimension equates with the radial dimension of groove upper inner wall.

Adjustable buss of the present utility model is placed in handrail tube and special inner chamber has between groove and the gradient bracket, can eliminate gap and noise easily and effectively, fixed armrest is combined with special bracket is firm, and can also play decorating action.

Embodiment

With reference to Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, adjustable buss of the present utility model is plastics or rubber product, supporting a kind of special inner chamber has groove 2A1 and gradient bracket 2A, its structural design is: body 3 band openings 31, the top has a circle cap head 32, appearance below cap head 32 is provided with the retaining boss 33 that a circle is complementary with bracket lumen channels 2A1, be provided with below the retaining boss 33 with its back inwall on six or N vertical convex surface guiding rib 34 corresponding concavers 35; Body 3 appearances of adjustable buss are the taper of inclination, and its gradient is corresponding with the gradient of this bracket inner chamber 2A2.The inner wall shape of adjustable buss is: be provided with a circle and the corresponding groove 36 of retaining boss on the back inwall at appearance retaining boss 33 places, establish six or N vertical convex surface guiding rib 34 below groove 36, its radial dimension equates with groove 36 upper inner wall 37 sizes.

During use, this will put into bracket 2A to adjustable buss, because adjustable buss band opening 31, the adjustable buss bore can be aligned according to the size in bracket 2A aperture in bracket 2A hole, when the retaining boss 33 of adjustable buss imbeds bracket 2A lumen channels 2A1, because the back of retaining boss 33 has groove 36, retaining boss 33 is very easy to enter among the bracket 2A lumen channels 2A1, and retaining boss 33 enters in the bracket 2A inner chamber and just moves back to come out.Because of the inwall of adjustable buss has vertically convex surface guiding rib 34 of six or N, its back corresponding concaver 35, fixed armrest pipe 1 is very easy to enter in the adjustable buss when installing.Because cap head 32 covers on the bracket 2A, therefore can also play decorating action.

Claims
