Description
Technical field
This utility model is related to a kind of pressure device of tyre, especially relates to a kind of multipoint positioning pressure device of tyre.
Background technology
It is presently used for the equipment of automobile tire changer, mostly smoothly will could dismount tire using machinery pressure tire arm,
And the pressure tire arm using in the market does not all have positioner, so dismount tire when, tyre rotation and drive tyre press wheel
Prop up wheel rim and cause resistance to tyre detacher, and easy scratch wheel rim.
Chinese patent CN203418938U discloses the pressure tire auxiliary dress by the slide positioning realizing tyre press wheel and upset
Put.It is made up of dismounting head, pressure tire arm seat, boss, pressure tire arm, elongated hole, positioning sleeve, pad, locating shaft and tyre press wheel, press tire arm seat
There is through hole centre, and there is boss bottom, and pressure tire arm seat is screwed in dismounting head top；There is elongated hole in the middle of pressure tire arm, press tire
Arm installs pad and positioning sleeve device on the boss of pressure tire arm seat by locating shaft；Equipped with pressure tire on the axle of termination of pressure tire arm
Wheel.The upper hole of work head is connected with the spindle nose of six square shafts tearing tire main frame open.This pressure tire auxiliary device, can force to be depressed into tyre beads
The following of working head circular arc does not make to slide on tyre edge.But this device locating effect is bad, and comparatively structure compares
Complexity, in-convenience in use.
Utility model content
The purpose of this utility model is exactly to overcome the defect of above-mentioned prior art presence to provide a kind of small volume, behaviour
Make convenient multipoint positioning pressure device of tyre.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of multipoint positioning presses device of tyre, including：
Pressure tire arm,
It is arranged on the tyre press wheel of pressure tire arm front end,
It is arranged on coaxial line half knuckle-tooth of pressure tire arm rear end,
The compression spring being connected with coaxial line semicircle tooth,
It is connected to compression spring top, control the handle of compression spring Compression and Expansion.
By fixing helical teeth and positioning helical teeth combines and constitutes, described fixing helical teeth is connected to pressure to described coaxial line half knuckle-tooth
The lower section of tire arm rear end, described positioning helical teeth is engaged with described fixing helical teeth, and positioning helical teeth connects compression spring.
Described fixing helical teeth is semicircular structure, and lateral surface is tooth type structures.
Described fixing helical teeth and pressure tire arm coaxial line.
It is the tooth type structures being meshed with fixing helical teeth inside described positioning helical teeth.
Described compression spring drives positioning helical teeth to move up and down.
The handle that described handle lifts upwards, the described compression spring of compression drives positioning helical teeth to move up and down.
The handle that described handle presses down on, the described compression spring of compression drives positioning helical teeth to move up and down.
Compared with prior art, this utility model small volume, may be installed arbitrarily rotatably pressure tire arm on, operation more
Plus it is convenient.

Specific embodiment
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment 1
A kind of multipoint positioning presses device of tyre, and its structure as shown in Figure 1-2, including pressure tire arm 6, is arranged on pressure tire arm 6 front end
Tyre press wheel 1, be arranged on pressure tire arm 6 rear end coaxial line half knuckle-tooth, the compression spring 4 being connected with coaxial line semicircle tooth, and
It is connected to compression spring 4 top, control the handle 5 of compression spring 4 Compression and Expansion.
The structure of coaxial line half knuckle-tooth is as shown in figure 3, be made up of fixing helical teeth 2 and positioning helical teeth 3 combination, fixing helical teeth 2
It is connected to the lower section of pressure tire arm 6 rear end, is semicircular structure, with pressure tire arm coaxial line, lateral surface is tooth type structures.Positioning helical teeth
It is the tooth type structures being meshed with fixing helical teeth 1 inside 3, positioning helical teeth 3 is meshed with fixing helical teeth 2, connects on positioning helical teeth 3
Connect compression spring 4.Compression spring 4 can drive positioning helical teeth 3 to move up and down.In the present embodiment, handle 5 be by downwards by
The handle of pressure, the described compression spring of compression drives positioning helical teeth to move up and down.The middle part of handle 5 is connected to pressure by support bar
On tire arm 6, during use, rotate pressure tire arm 6 by lower handle 5, allow tyre press wheel 1 away from wheel rim 5-10mm, release handle 5, at this moment press
Contracting spring 4 pushes positioning helical teeth 3, is engaged with fixing helical teeth 2, reaches the effect of fixing pressure tire arm 6.
Embodiment 2
A kind of multipoint positioning presses device of tyre, and as shown in Figure 3-4, its structure is roughly the same with embodiment 1, difference for its structure
Place is, the handle 5 adopting in the present embodiment is the handle lifting upwards, makes compression spring quilt by carrying handle 5 upwards
Compression, and then drive positioning helical teeth to move up and down.
