Abstract
The utility model discloses a labor-saving tire change device integrating a jack. The device comprises a jack and a disc tire changer, wherein the disc tire changer is fixed on a hand shank of the jack; an upper disc, a lower disc and four handles are arranged on the disc tire changer; the handles are fixed between the upper and lower discs; and a twisting ring matched with a screw on the tire in size is arranged at the tail end of each handle. The jack and the disc tire changer are effectively combined, and the disc tire changer is fixed on the hand shank of the jack, so that each handle of the tire changer is rotated when the jack lifts the tire, and then the screw on the tire is unscrewed. The labor-saving tire change device disclosed by the utility model is simple to operate, yields twice the result with half the effort, and improves the efficiency.
Description
Technical field
The utility model relates to the tire field, is specifically related to a kind of laborsaving device of tyre that changes that integrates jack.
Background technology
Tire is the annular arrangement elastic rubber product that rolls the ground connection of various vehicles or mechanically assembling.Usually be installed on the alloy rim, can support vehicle body, the buffering foreign impacts realizes the rideability that contacts and guarantee vehicle with the road surface; Tire be everlasting complicated and exacting terms under use, it is bearing various distortion, load, power and high cold service in motion, so must have higher load-carrying properties, tractive property, cushion characteristic; Simultaneously, also require to possess high-wearing feature and flexible resistance, and low rolling resistance and heat generation; Half of world's consumption rubber mass all is for tire production.
Tire has been nowadays social requisite, and along with " the tire industry industry policy " of issuing and implementation, tire recall is also put on agenda, and tire also receives increasing concern.Tire is one of vitals of automobile, and it directly contacts with the road surface, and automotive suspension suffered impact when jointly relaxing running car, guarantees that automobile has good driving comfort and riding comfort; Guarantee that there is good tack on wheel and road surface, improve traction property, braking ability and the crossing ability of automobile; Bearing the weight of automobile, the vital function that tire is risen on automobile more and more is subject to people's attention.
Tire is in the vehicle traveling process, the parts of unique direct contact bottom surface, fact proved, numerous car accedents be exactly the problem that comes from tire, wherein the decorative pattern of tire is very important, and it can guarantee the actv. earth-grasping force, for decorative pattern, may wear to normally to a certain degree, tire just need to have been changed.Simultaneously, by the observation to tyre contact patch, also can judge vehicular four wheels location and suspension and whether have hidden danger.
Be not difficult to find out, the replacing of tire has become recurrent action in the daily life, and during the general replacement tire, common tool is jack.So-called jack is to utilize worm drive to push up a kind of lifting or the screwing tool of lifting heavy thing, is usually used in automobile repair and the mechanical erection.During work, weight is pressed on the top pad, and the strand thick stick is penetrated in the hole on screw rod top, and turn strand thick stick, screw rod are done by screw thread in swivel nut and moved up and down, thus jack-up or put down weight.Swivel nut is set in the base, with the screw location, is convenient to after the wearing and tearing change.The top cushion cover is at the screw rod top, and its sphere forms the fitting surface that transmits load-bearing, by the screw locking, makes the relative screw rod rotation of top pad and do not come off.
The tire method of changing commonly used is at present: first screw is back-outed with sleeve, could all down be unloaded screw and tire after coming on the roof with jack.Its complicated operation, inefficiency.
The utility model content
In order to solve the defective that exists in the prior art, the utility model provides a kind of jack and disk has been changed the device of tyre that changes that the tire device combines.
The utility model is achieved through the following technical solutions:
Comprise that jack and disk change the tire device, described disk changes on the handle that the tire device is fixed on jack, described disk changes the tire device and is provided with up and down two disks, 4 handles, and handle is fixed on up and down between two disks, and the end of handle is provided with and the tighten up a screw stubborn ring of size coupling of tire.
Angle between the described adjacent handle is 90 °.
Described stubborn ring is integrated with handle and is vertical.
The end of described handle is provided with screw and nut.
The beneficial effects of the utility model: jack and disk are changed the tire device effectively combine, and disk changed on the handle that the tire device is fixed in jack, in the process of jack rising tire so that change the handle rotation of tire device, back out the screw on the tire, simple to operate, get twice the result with half the effort, improved efficient.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that disk changes the tire device;
Fig. 3 is the partial enlarged drawing that disk changes the tire device;
Wherein, 1, jack, 2, baffle ring, 3, handle, 4, disk changes the tire device, 5, handle, 6, twist ring, 7, screw, 8, nut.
The specific embodiment
By following examples the utility model is described in further detail.
In conjunction with Fig. 1-3, a kind of laborsaving device of tyre that changes that integrates jack, comprise that jack 1 and disk change tire device 4, described disk changes on the handle 3 that tire device 4 is fixed on jack 1, described disk changes tire device 4 and is provided with up and down two disks, 4 handles 5, handle 5 is fixed on up and down between two disks, and the end of handle 5 is provided with and the tighten up a screw stubborn ring 6 of size coupling of tire; Jack and disk are changed the tire device effectively combine, and disk is changed on the handle that the tire device is fixed in jack, in the process of jack rising tire so that change the handle rotation of tire device, back out the screw on the tire, simple to operate, get twice the result with half the effort, improved efficient.
Angle between the described adjacent handle 5 is 90 °, and is firmly balanced.
Described stubborn ring 6 is integrated with handle 5 and is vertical, can produce one stubborn power, backs out screw.
The end of described handle 5 is provided with screw 7 and nut 8, and is for convenience detach.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
