Description
Technical field
The utility model is related to a kind of very heavy top part, specifically a kind of telescoping handle with reliable location structure.
Background technology
Jack is a kind of widely used lifting instrument.Conventional jack generates power by hydraulic system and promotes weight
Object, and hydraulic system mainly constantly drives oil pump pump core by the handle for being connected to press hand, top pressure supports the hydraulic oil pumped out again
The oil cylinder of weight simultaneously makes it gradually rise, thus to obtain lifting effect.Handle as power arm is usually by two section handle grafting
It is formed by connecting, conventional inserting mode is that matched banjo connector is made in the splicing position of two section handles, then uses screw horizontal
Two section handles are fixed to plugging position is passed through；This is just needed using box spanner manually by screw-driving, cumbersome, in addition
The two section separated occupied spaces of handle are big, and are easy to lose.Therefore, it is necessary to be improved to jack handle.
Utility model content
The purpose of the utility model is to overcome the deficiencies of above-mentioned background, provide a kind of flexible with reliable location structure
Handle, the jack handle have the characteristics that it is easy to operate, save space, stable and reliable in work.
The technical scheme that the utility model is provided is as follows：
A kind of telescoping handle with reliable location structure includes the front hand grip and defensive position of intermediate perforation in tubular construction
Handle, it is characterised in that：The back handle be movably inserted into the tube chamber of front hand grip and by location structure realize front hand grip with
The connection of back handle；The location structure includes the work for being arranged in the location hole of back handle front and being buckled by spring sheetmetal force
Dynamic fixed pin, and it is produced on front and rear sides and the preceding pin hole that can coordinate respectively with movable fixed pin and the rear pin hole of front hand grip.
The spring sheetmetal, which is buckled, to be bent into V-shaped and is located in the tube chamber of back handle；One end that spring sheetmetal is buckled is fixed
The movable fixed pin.
It is fixed with for the positioning screw against back handle front end face, with profit on the left of the intraluminal preceding pin hole of front hand grip
Movable fixed pin quickly positions.
The necking to pipe contract, the outer circumference surface of the back handle front are provided at the rear end nozzle of the front hand grip
Be provided with the matched positioning step of necking, quickly positioned with sharp movable fixed pin, and to prevent front hand grip and back handle from sliding
It is de-.
The distance of the positioning screw to preceding pin hole is identical at a distance from back handle front end face to movable fixed pin；After described
The distance of pin hole to necking is identical at a distance from movable fixed pin to positioning step.
The rear portion of the back handle is equipped with taper knob.
The utility model has the beneficial effects that：Back handle in the utility model, which can be inserted in front hand grip, to be preserved, and is saved
Space and not easy to lose；Front hand grip is fixedly connected with back handle using movable fixed pin, can lengthen or reduce handle as needed
Length；Movable fixed pin is detached from pin hole when pressing movable fixed pin, and back handle is facilitated to be slided in front hand grip tube chamber；Separately
Outside, the positioning screw in front hand grip and necking can be such that movable fixed pin is accurately located where upper, the preceding pin hole of front hand grip
On periphery, then only need rotation back handle that can position movable fixed pin into pin hole, stable and reliable in work, operation is just
Profit.
Description of the drawings
Fig. 1 is one of cross-sectional view of the utility model (before movable fixed pin is located in pin hole).
Fig. 2 is two (movable fixed pin is located in rear pin hole) of the cross-sectional view of the utility model.
Fig. 3 is the cross-sectional view of existing jack handle.
Specific implementation mode
With reference to the accompanying drawings of the specification, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
Telescoping handle with reliable location as shown in the figure, including front hand grip 1 and back handle 2, the front hand grip is with after
Handle is the tubular structure of intermediate perforation, and the internal diameter of front hand grip is more than the outer diameter of back handle, before ensureing that back handle can be inserted
Make stretching motion and rotation in handle and in front hand grip tube chamber；The back handle is plugged on by location structure in front hand grip；
Spring sheetmetal buckles 3 and is bent into V-shaped and is located in the tube chamber of back handle.
In the location structure, buckled in the location hole of 4 laterally inserted back handle front of movable fixed pin and with spring sheetmetal
Fixed (riveting is recommended to fix), the rear pin hole 5 that can coordinate with movable fixed pin are opened in the rear portion of front hand grip, can be fixed with activity
The preceding pin hole 6 of pin cooperation is opened in the front of front hand grip.Movable fixed pin with preceding pin hole or the mating of rear pin hole by inciting somebody to action
Forward and backward handle is connected to one, and ensures that back handle will not be moved back and forth and be rotated in front hand grip tube chamber when in use；And
And as long as pressing loose pin forward and backward handle can disengage, it avoids to make to be screwed and needs to use box spanner
Inconvenience.
In order to facilitate movable fixed pin and forward and backward pin hole, accurately and reliably grafting positions, and the preceding pin hole of the front hand grip is left
Side (left side in Fig. 1, Fig. 2) is fixed with positioning screw 7, distance and the back handle front end face to activity of positioning screw to preceding pin hole
The distance of fixed pin is identical；When back handle front end face is resisted against positioning screw, before movable fixed pin is just at front hand grip
On the circumferential surface, rotation back handle can make in activity orientation finger setting to preceding pin hole for pin hole institute.The rear end pipe of the front hand grip
The necking 8 to pipe contract is provided at mouthful (diameter of necking is more than the diameter of back handle)；The front outer circle of the back handle
Circumferential surface is provided with and the matched positioning step of necking 9.Distance and movable fixed pin to positioning table of the pin hole to necking after described
The distance of rank is identical；When the positioning step of back handle and necking abut, movable fixed pin is in the rear pin hole of front hand grip
On the circumferential surface, rotation back handle can make in activity orientation finger setting to rear pin hole for institute.
The back handle top is equipped with taper knob 10；To be conveniently operated personnel's gripping, and keep handle monnolithic case
It is regular.
The application method of the utility model is：
Movable fixed pin is pressed, so that back handle is disengaged with front hand grip, back handle can be stretched out, until positioning step top
It can not be moved out at necking, rotating back handle at this time can be such that movable fixed pin positions into rear pin hole, and forward and backward handle is consolidated
Fixed connection.After use, movable fixed pin is pressed again, and back handle is disengaged with front hand grip, back handle is pushed into front hand grip, directly
It supports to positioning screw and can not push forward to back handle front end face, rotating back handle at this time makes movable fixed pin position to preceding pin hole
In, forward and backward handle can be fixedly connected, complete to preserve.
Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, this practicality is new
Type is not limited to above example, can also there is many variations.Those skilled in the art can be from disclosed by the utility model
All deformations for directly exporting or associating in content, are considered as the scope of protection of the utility model.
