Abstract
The utility model discloses a spanner for screw tightness, which is composed of a support plate, a hydraulic jack, a connecting rod, a shaft rod, a shaft sleeve, a sleeve barrel and a shaft washer. The support plate, the hydraulic jack and the connecting rod form a triangular; the hydraulic jack drives the shaft rod to rotate through the connecting rod to realize the screw tightness. The utility model has the following advantages: by utilizing the characteristics of the jack of little force and strong top force, the problem of labour-consuming of the screw tightness is solved; the utility model is an effective tool for the screw tightness of the automobile tyre.
Description
The utility model relates to a kind of screw degree of tightness instrument, particularly a kind of very heavy pulling of screw degree of tightness of motor tire degree of tightness.
In industries such as building, installation, repairing, usually need specific screw is screwed or unscrews, owing to do not have special use, effective tool, therefore, operating personal is required great effort in screw being carried out the degree of tightness operation very much.For example, the degree of tightness of motor tire screw is generally carried out with socket wrench, uses this socket wrench extremely to require great effort, and needs the several people to exert oneself together sometimes.
The purpose of this utility model provides very heavy the pulling of a kind of ten minutes labour-saving screw degree of tightness.
The purpose of this utility model is achieved in that it is to be made of supporting plate, oil jack, connecting rod, axostylus axostyle, axle sleeve and sleeve.End both sides at supporting plate are provided with blowout patche, and axostylus axostyle is inserted in the blowout patche, connects connecting rod from the axostylus axostyle between the blowout patche, and connecting rod links to each other with the push rod of oil jack by the hinge key.The bottom of oil jack links to each other with the other end of supporting plate by the hinge key, is provided with at the two ends of axostylus axostyle and the corresponding prismatic of the jack of axle sleeve, and the profile of axle sleeve is a prismatic, and its shape matches with the jack of sleeve.
The utility model is a top power of utilizing jack powerful, drives the sleeve rotation by moving part screw is carried out degree of tightness.For this reason, the utility model converts the up-and-down movement of jack push rod to axostylus axostyle rotatablely move by connecting rod, and axostylus axostyle drives the sleeve rotation by axle sleeve, and sleeve drives the screw rotation simultaneously, thereby realizes the degree of tightness to screw.Because the screw specification varies in size, therefore, need to be equipped with complete axle sleeve and the sleeve of a cover specification size.Axostylus axostyle one end is used for the screwing of screw, and the other end is used for unscrewing screw.During use,, select corresponding sleeve and axle sleeve for use according to the specification size of screw, insert good after, press the handle of oil jack, make the push rod of oil jack promote connecting rod and rotate, connecting rod drives axostylus axostyle successively and sleeve rotates, thereby makes screw means or unscrew.
In degree of tightness, because therefore each screw present position height difference, is positioned at place, oil pressure thousand tops and establishes the stent foot that highly can regulate on supporting plate as the motor tire screw.Stent foot can be various forms, is T-shaped as stent foot, is provided with row's pin hole on its pole, and pole is inserted in the hole of supporting plate and passes through dowel fixes.
For ease of carrying, roll over dress, be flexible connection between each parts of the present utility model.Blowout patche is an annular arrangement, and makes it to fix with supporting plate by screw.For the purpose of simple and convenient, blowout patche also can be for inwardly being provided with the semi-round ring shape that axostylus axostyle is imported and exported.
The utility model compared with prior art, its remarkable advantage is to utilize the characteristics that jack is firmly little, top power is big, when having solved the screw degree of tightness effort problem, be the effective tool of motor tire screw degree of tightness.Simultaneously, it is complete that the utility model also has size specification, carries, rolls over and adorn advantage easily.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is a structural representation of the present utility model.
Embodiment: the screw degree of tightness jack that the utility model is made comprises supporting plate 1, oil jack 2, connecting rod 3, axostylus axostyle 4, axle sleeve 5, sleeve 6, blowout patche 7 and stent foot 8.Oil jack 2 is by cutting with scissors the end that key is connected supporting plate 1, and blowout patche 7 is fixed on the both sides of the other end of supporting plate by screw.Axostylus axostyle 4 interts in blowout patche 7, and connecting rod 3 is vertically fixed on the axostylus axostyle 4.The push rod of connecting rod 3 and oil jack is connected by the hinge key.The two ends of axostylus axostyle 4 are square boss, and axle sleeve 5 is the attaching parts of axostylus axostyle 4 and sleeve 6, and therefore, the jack of axle sleeve 5 matches with the projection at axostylus axostyle 4 two ends, and the profile of axle sleeve 5 matches with the jack of sleeve 6.An end that is positioned at oil jack on supporting plate 1 has a through hole, the pole of T-shaped stent foot 8 is inserted in the through hole of supporting plate 1, be provided with row's pin hole on the pole of stent foot 8, stent foot 8 makes it fixing with supporting plate 1 by pin, regulates its height simultaneously.
