Abstract
The utility model relates to the improvement of a wheeled jack. The back part of a U-shaped valve seat is provided with the connecting supporting seat of a lifting hand which is connected with the lifting hand by the bolt of the lifting hand. The U-shaped valve seat is provided with a pump body and a pump core in inclination arrangement. One end of the pump core is hinged with the convex part of the lifting hand and is placed on one end of a sliding valve rod to be connected with the handle by a universal joint. Thus The utility model has the characteristics of reasonable structure, light weight, small size, large hoisting capacity, convenient operation, etc.
Description
The utility model relates to a kind of improvement of garage jack.
Existing garage jack can be divided into light-duty and heavy two big classes.The operating handle of light-duty garage jack all adopts with the oil cock structure of control jack lifting and separates setting, handle can not be in pressing hand the direct control oil cock, can only be from another one angle operation oil cock switch, promptly need through following actions: (1) fastens oil cock; (2) handle inserts and presses hand hole, and the guiding jack is to control position; (3) the handle front end is transferred to from pressing hand hole, aims at and unclamps oil cock; (4) handle inserts again and presses hand hole, rotates an angle, and the pin projection of being located at the handle front end is put in the L groove of pressing the hand rear end, retracts jack.Volume is little, in light weight though this jack has, and hoisting capacity is relatively large, and advantage easy to carry is generally only made driver's tool and used.Because the aforesaid operations step is various, and long handle will be aimed at comparatively difficulty of less oil cock, use inconvenience.Therefore, the hand of pressing of heavy garage jack is connected with wallboard (or stay bearing plate) by pressing the hand screw, and wallboard and valve part adopt captives joint, and valve body is connected with pressing then to adopt between the hand to assemble indirectly.Though the operation of this jack is comparatively convenient, volume, cost are bigger, Heavy Weight, carrying trouble.The occasion that generally is used for fixing use.
The purpose of this utility model provides a kind of rational in infrastructure, and overall weight is light, and volume is little, the garage jack that hoisting capacity is bigger and easy to operate.
Major scheme of the present utility model is: is provided with at the rear of U-shaped valve seat and presses hand and connect bearing, and by pressing the hand bolt and pressing palmistry and be connected; Tilting on the U-shaped valve seat have the pump housing and a pump core, an end of pump core be located at press hand press that hand is protruding to be hinged; And the end at the valve rod of draining the oil is connected with handle through universal-joint.Wherein, press gloves pressing to be provided with between hand and the handle; One end is linked to each other with handle by the handle pin, and the other end sells fixed by pressing the gloves pin mutually with the end of universal-joint.In addition, press outside the straight pin of hand on protruding being located at, be with cylindrical ring, and be interlockingly connected by cylindrical ring and pump core.
Below by embodiment, the utility model is described specifically.
Accompanying drawing 1 is a kind of partial front elevation view of the present utility model.
Accompanying drawing 2 is E-E cut-away views that accompanying drawing 1 amplifies.
Accompanying drawing 3 is birds-eye vieies of accompanying drawing 1 part.
Accompanying drawing 4 is a kind of cutaway views of pressing hand in the utility model.
Accompanying drawing 5 is a kind of birds-eye vieies of pressing hand in the utility model.
Embodiment: what be provided with a front end reducing in pressing hand (9) presses gloves (91), and its rear end offers L shaped breach (95), and its necking end then sells fixed by pressing gloves pin (94) with an end of universal-joint (13) mutually.Because this pin is longer than the aperture of pressing the hand reducing, makes it to press glove port (91) and can only rotate and can not do axial moving.The other end of universal-joint is connected with the tilting valve rod of draining the oil (14) on U-shaped valve seat (4).(referring to accompanying drawing 1 to accompanying drawing 3) described to be pressed hand (9) to press hand protruding (90) with parallel two of being located at its underpart is to adopt the casting embryo to process (referring to accompanying drawing 4 and accompanying drawing 5); Be provided with straight pin (7) on protruding, its outer cylindrical ring (8) that is with pressing hand; Be provided with in the end of the pump core (5) of tiltedly being located at U-shaped valve seat (4) and buckle neck, cylindrical ring (8) is clamped on it, and both are interlockingly connected.Simultaneously, by pressing hand bolt (42), will press hand (9) and connect on the bearing (41).
During use, handle (92) insertion is pressed in the gloves (91), the handle pin (93) of being located at the handle front end puts in the L shaped breach (95) of lining, the handle that rotates drives with this and presses the whole rotation of gloves (92), thereby drive valve rod (14) rotation of draining the oil by universal-joint (13), thereby reach closing and opening of oil cock.
After fastening oil cock, the pressing handle, straight pin (7) and cylindrical ring (8) that dependence is pressed on the hand protruding (90) drive tilting pump core (5), make it in the pump housing (6), to move up and down, according to hydraulic principle, hydraulic oil in the low-pressure reservoir is pressed into pressure hole, and the piston rod (2) that makes it jack moves and the jack-up load along axle cylinder (3).After treating that operation finishes, open oil cock, the jack off-load descends.
In addition, the L shaped breach of lining also can move whole jack by the pulling handle except rotation drives the universal-joint rotation.
Therefore, the utlity model has rational in infrastructure, complete machine is in light weight, volume is little, material is economized, cost is low, The characteristics such as lifting capacity is bigger, and is easy to operate.
Claims (3)
1, a kind of garage jack by valve seat, piston rod, press hand and stay bearing plate, roller and pump core, the pump housing are formed, is characterized in that being provided with at the rear of U-shaped valve seat (4) and presses hand and connect bearing (41), and by pressing hand bolt (42) and pressing hand (9) and be connected; Go up tilting the have pump housing (6) and pump core (5) at U-shaped valve seat (4), an end of pump core (5) and be located at the hand protruding (90) of pressing of pressing hand and be hinged; And the end in oil cock (14) is connected with handle (92) through universal-joint (13).
