Abstract
A jack-used flat cotter for fixing a screw comprises a flat cotter body having a screw hole arranged in the center of the flat cotter body, wherein one end of the flat cotter body is provided with a baffle having a diameter larger than that of the flat cotter body while the other end, opposite to the baffle, is provided with a projection part having a diameter smaller than that of the flat cotter body. According to the utility model, one end of the flat cotter body is configured to be a big end while the other end is configured to be a small end, so that while in use, the big end provides the function of position limiting and the small end increases the contact area of the surface of the flat cotter body and a support; and holes are arranged at two ends of the flat cotter body, thereby achieving the purposes of saving materials and reducing cost. The flat cotter has a simple structure and high practicality.
Description
Technical field
The utility model relates to a kind of cotter pilotage, particularly relates to the cotter pilotage that is used for fixing screw mandrel on the jack.
Background technique
Jack is that a kind of the top with rigidity lifted part as fitting device, through the light little crane gear of top bracket or bottom claw jacking weight in stroke.Can be divided into three kinds of tooth bar jack, screw jack and hydraulic jack by structure characteristic.Jack is a kind of lifting the simplest highly little crane gear.It has two kinds of mechanical type and hydraulic types.The mechanical type jack has rack-type and spiral two kinds again, because initial weight is little, the operation effort generally only is used for flight-line maintenance work, and is inapplicable in repairing the bridge process.The hydraulic jack compact structure, stable working has self-locking action, thus use extensively,
These jack all are to utilize screw mandrel to pass the inner unthreaded hole of cotter pilotage to be fixed on the support in the process of using, yet the existing cotter pilotage structure that is used for being used for fixing on the jack screw mandrel is reasonable inadequately, can not make things convenient for, firm being fixed on the support.
Therefore, need to be used for fixing on the jack cotter pilotage of screw mandrel especially, to solve the problem that exists in the existing technology.
The model utility content
The purpose of the utility model is in order to solve the defective of cotter pilotage in the existing technology, to provide the cotter pilotage that is used for fixing screw mandrel on the car jack to solve the problems referred to above.
To achieve these goals, the technological scheme of the utility model is following:
The cotter pilotage that is used for fixing screw mandrel on the jack; Comprise cylindrical body cotter pilotage body; Said cotter pilotage body comprises the unthreaded hole that is arranged on cotter pilotage body centre; Said unthreaded hole two ends and the contacted position of this external surface of cotter pilotage are provided with concave station, it is characterized in that: an end of said cotter pilotage body is provided with baffle plate, and the diameter of said baffle plate is greater than the diameter of cotter pilotage body.
In the utility model, the concave station of said cotter pilotage body is rectangular concave station.
In the utility model, the other end of said cotter pilotage body overhead gage is provided with the projection of diameter less than the cotter pilotage body.
In the utility model, said cotter pilotage body two ends are respectively arranged with the hole that is used to save material.
In the utility model, said hole and the contacted position of this external surface of cotter pilotage that is used to save material is provided with chamfering.
The cotter pilotage that is used for fixing screw mandrel on the jack of the utility model is compared with existing product, and an end of cotter pilotage body is arranged to big end; One end is arranged to small end, and when in use, big end has played position-limiting action; Small end increases the area of contact of cotter pilotage body surface and support, is provided with unthreaded hole at cotter pilotage body two ends, when making production; Ensureing under the constant prerequisite of cotter pilotage body practicability, removing a part of steel of cotter pilotage body interior, the purpose that reach economical with materials, reduces cost; Contacted position, screw two ends and cotter pilotage surface is provided with chamfered transition in the middle of the cotter pilotage body, avoids the scuffing of staff, has also reached effect easy to use; Simple in structure, very practical.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model sectional view.
Embodiment
For making structure characteristic of the utility model and the effect of being reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1 and Fig. 2; The cotter pilotage that is used for fixing screw mandrel on the car jack; Comprise cylindrical cotter pilotage body 100, cotter pilotage body 100 comprises the unthreaded hole 110 that plays fixation that is arranged on cotter pilotage body 100 centres, and unthreaded hole 110 two ends and the contacted position of cotter pilotage body 100 outer surfaces have been provided with the concave station 120 that makes things convenient for the installation effect; One end of cotter pilotage body 100 is provided with baffle plate 130, and the diameter of baffle plate 130 is greater than the diameter of cotter pilotage body 100.
The concave station of cotter pilotage body 100 is rectangular concave station, makes structure more reasonable, makes things convenient for the work of the utility model.
The other end of cotter pilotage body 100 overhead gages 130 is provided with the projection 140 of diameter less than cotter pilotage body 100, and when mounted, (area of contact that does not show among the figure makes installation more firm, has strengthened the practicability of the utility model with support to increase cotter pilotage basis 100.
The hole and the contacted position of cotter pilotage body 100 outer surfaces that are used to save material are provided with chamfering, the scuffing when having avoided cotter pilotage to contact with staff.
The cotter pilotage that is used for fixing screw mandrel on the jack of the utility model is compared with existing product, and an end of cotter pilotage body 100 is arranged to big end; One end is arranged to small end, and when in use, big end has played position-limiting action; Small end increases the area of contact of cotter pilotage body 100 surfaces and support, is provided with unthreaded hole at cotter pilotage body 100 two ends, when making production; Ensureing under the constant prerequisite of cotter pilotage body 100 practicability, removing a part of steel of cotter pilotage body 100 inside, the purpose that reach economical with materials, reduces cost; Contacted position, screw two ends and cotter pilotage surface is provided with chamfered transition in the middle of cotter pilotage body 100, avoids the scuffing of staff, has also reached effect easy to use; Simple in structure, very practical.
In sum; Be merely the preferred embodiment of the utility model; Be not to be used for limiting the scope that the utility model is implemented; All equalizations of doing according to the described shape of the utility model claim scope, structure, characteristic and spirit change and modify, and all should be included in the claim scope of the utility model.
