Abstract
The utility model relates to an automatic child machine is torn open in locking, including the box, connect stand on the box, connect and to follow tearing fetal head open, placing the mount pad of tire of stand up -and -down motion on the stand, the below of mount pad is equipped with the cylinder, the piston lower extreme of this cylinder is opened has the bar hole, has seted up the bar hole on the center pin is connected with the mount pad, is connected with the bar aperture fixed pin of seting up on the piston, the top of center pin is fixed with the awl piece of locking tyre rim. Compared with the prior art, the utility model discloses utilize the principle of piston up -and -down motion, reach the mesh of locking the steel ring to can practice thrift the time of locking, reach quick locking, and alleviate intensity of labour.
Description
Technical field
This utility model relates to one and tears device of tyre open, especially relates to a kind of auto lock tyre detacher.
Background technology
It is presently used for the equipment of automobile tire changer, by casing, a column, tears fetal head, workbench composition open; Workbench is made up of two cylinders and claw, and its operation principle is: utilizes cylinder to open claw clamping steel ring, reaches the requirement of dismounting tire.
Tyre detacher is for clamping steel ring now, mainly has two ways, and the first is to utilize claw clamping steel ring with workbench, and the second is tire mounting seat, utilizes a central shaft and tapered sleeve, with nut, the centre bore of steel ring is locked. The shortcoming of the first is as the stroke of the increase of steel ring, workbench and claw all to be needed to increase; The shortcoming of the second is to load onto steel ring fastening nut to waste time and energy.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of auto lock tyre detacher saved the locking time, reduce labor intensity is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of auto lock tyre detacher, including casing, the column being connected on casing, is connected on column the mounting seat tearing fetal head, placement tire open that can move up and down along column,
Mounting seat be connected with cylinder, the piston of this cylinder has bar hole,
The central shaft being connected with mounting seat offers bar hole, is connected with the bar shaped aperture steady pin offered on piston, the cone block being fixedly arranged above locking wheel tyre steel ring of central shaft.
Described piston has horizontal bar hole.
The bar hole with angle is offered in the both sides of described central shaft, and the angle between this bar hole and centrage of central shaft is 30 ��-40 ��, and as preferred technical scheme, the angle between bar hole and centrage is 37 ��.
The axis of described central shaft is offered a straight hole, a location compression spring is installed at the bottom of the hole of this straight hole.
Described central shaft lower end is provided with the groove inserting in mounting seat by central shaft.
Described location compression spring navigates to central shaft groove and steady pin same level position.
Described cone block is fixedly connected on central shaft through nut.
When the piston is moving down, driving the steady pin in bar hole to move downward, steady pin drives central shaft to move downward, and then band mantle block moves downward locking steel ring, when the piston is moving up, drive the steady pin in bar hole to move upward, and then band mantle block moves upward and unclamps steel ring.
Compared with prior art, this utility model utilizes the principle of piston up-down, reaches the purpose of locking steel ring such that it is able to saves the time of locking, reaches quick locking, and reduce labor intensity.

Fig. 2 is mounting seat internal structure schematic diagram;
Fig. 3 is the structural representation at bar hole place.
In figure, 1-casing, 2-column, 3-tear fetal head, 4-mounting seat, 5-central shaft, 6-cone block, 7-nut, 8-cylinder, 9-piston, 10-steady pin, 11-location compression spring open.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Embodiment
A kind of auto lock tyre detacher, its structure is as it is shown in figure 1, include casing 1, the column 2 that is connected on casing 1, be connected on column 2 and can tear fetal head 3 open along what column 2 moved up and down, place the mounting seat 4 of tire. It is connected with cylinder 8 in mounting seat 4, piston 9 lower end of this cylinder 8 has horizontal bar hole, the bar hole with angle is offered in the both sides of the central shaft 5 being connected with mounting seat 4, angle between this bar hole and centrage of central shaft is 30 ��-40 ��, in the present embodiment, angle between bar hole and centrage is 37 ��, as shown in Figure 3. Steady pin 10 is through the bar hole of central shaft 5 with piston 9, and its structure is as in figure 2 it is shown, the top of central shaft 5 is fixed with the cone block 6 of locking wheel tyre steel ring through nut 7.
In addition, the axis of central shaft 5 is offered a straight hole, compression spring 11 in location is installed at the bottom of the hole of this straight hole. There is a groove central shaft 5 lower end; Being inserted by central shaft 5 in mounting seat 4, location compression spring 11 navigates to central shaft 5 groove and steady pin 10 same level position.
When piston 9 moves downward, the steady pin 10 in bar hole is driven to move downward, steady pin 10 drives central shaft 5 to move downward, and then band mantle block 6 moves downward locking steel ring, when piston 9 moves upward, drive the steady pin 10 in bar hole to move upward, and then band mantle block 6 moves upward and unclamps steel ring.
