Abstract

A detaching mechanism of wheel comprises a fixing component [6] fixed on a frame [10], wheel axis sleeve [3] fixed on the fixing component [6], a wheel axis [15] with one end inserting into the wheel axis sleeve [3] and a wheel arranged on the wheel axis [15]. The utility model is characterized in that the wheel axis [15] is provided with a circular groove [18] of the wheel axis; a button [1] is connected to the fixing component [6] by sliding. The button [1] slides along the axis of the wheel axis [15]. A pressing spring [2] is arranged between the button [1] and the wheel axis sleeve [3]. The button [1] is provided with a spring-key-bar [4]. The spring-key-bar can switch between the first work spot and the second work spot when pushing or loosening the button, thus can detach wheel, and operation is convenient.

Description

The disassembly mechanism of wheel

The utility model relates to the wheel disassembly mechanism of vehicles such as a kind of vehicle, particularly trailers, Three-wheel car.

In the prior art, being connected between the wheel shaft of vehicle and the vehicle frame captiveed joint, and when packed and transported, wheel need break away from vehicle frame, reducing packaging volume, and the wheel shaft of existing wheel since with vehicle frame between captive joint, therefore dismounting is very inconvenient.

The purpose of this utility model is to provide a kind of disassembly mechanism of the wheel that can be easily wheel be disassembled from the vehicle frame.

The technical solution of the utility model is: a kind of disassembly mechanism of wheel, comprise the connecting element that is fixed on the vehicle frame, be fixed in the axle sleeve on the described connecting element, one end is inserted in the wheel shaft in the described axle sleeve, be arranged at the wheel on the described wheel shaft, have the annular groove of wheel shaft on the described wheel shaft, knob and described connecting element sliding block joint, make described button radially sliding along wheel shaft, be provided with stage clip between described button and the axle sleeve, described button is provided with positioning bar, this positioning bar has two kinds of control positioies: first control position is a latched position, and this moment, positioning bar was inserted in the annular groove of wheel shaft; Second control position is a unlocked position, and this moment, positioning bar broke away from the annular groove of wheel shaft.

The utility model compared with prior art has following advantage:

When pressing button or release button, the positioning bar on the button can be changed between second control position or first control position, and when second control position, wheel shaft can be transferred to from axle sleeve, then can removing vehicle tyres, and therefore easy to operate.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a front view of the present utility model;

Accompanying drawing 2 is the A-A direction cutaway view of accompanying drawing 1; Wherein:

[1], button; [2], stage clip; [3], axle sleeve; [4], positioning bar; [5], brake lever; [6], connecting element; [7], brake lever attaching parts; [8], stage clip; [9], back rotating shaft; [10], vehicle frame; [11], brake connecting rod; [12], front rotary shaft; [13], brake handle; [14], brake is rotating shaft; [15], wheel shaft; [16], brake disc; [17], the pilot hole of brake lever; [18], the annular groove of wheel shaft;

Embodiment: referring to accompanying drawing 1 to accompanying drawing 2, a kind of disassembly mechanism of wheel, comprise the connecting element [6] that is fixed on the vehicle frame [10], be fixed in the axle sleeve [3] on the described connecting element [6], one end is inserted in the wheel shaft [15] in the described axle sleeve [3], be arranged at the wheel on the described wheel shaft [15], have the annular groove [18] of wheel shaft on the described wheel shaft [15], knob [1] and described connecting element [6] sliding block joint, make described button [1] radially sliding along wheel shaft [15], be provided with stage clip [2] between described button [1] and the axle sleeve [3], described button [1] is provided with positioning bar [4], this positioning bar [4] has two kinds of control positioies: first control position is latched position (as shown in Figure 2), and positioning bar this moment [4] is inserted in the annular groove [18] of wheel shaft; Second control position is a unlocked position, and positioning bar this moment [4] breaks away from the annular groove [18] of wheel shaft, and then wheel shaft [15] can be pulled out in axle sleeve [3], makes wheel to take off from wheel shaft [15].

Referring to accompanying drawing 1 and accompanying drawing 2, an end of described stage clip [2] is against on the button [1], and the other end of stage clip [2] is against on the axle sleeve [3].

Claims

1, a kind of disassembly mechanism of wheel, comprise the connecting element [6] that is fixed on the vehicle frame [10], be fixed in the axle sleeve [3] on the described connecting element [6], one end is inserted in the wheel shaft [15] in the described axle sleeve [3], be arranged at the wheel on the described wheel shaft [15], it is characterized in that: the annular groove [18] that has wheel shaft on the described wheel shaft [15], knob [1] and described connecting element [6] sliding block joint, make described button [1] radially sliding along wheel shaft [15], be provided with stage clip [2] between described button [1] and the axle sleeve [3], described button [1] is provided with positioning bar [4], this positioning bar [4] has two kinds of control positioies: first control position is a latched position, and positioning bar this moment [4] is inserted in the annular groove [18] of wheel shaft; Second control position is a unlocked position, and positioning bar this moment [4] breaks away from the annular groove [18] of wheel shaft.
