Abstract

The utility model discloses a telescopic screw. The telescopic screw comprises a screw cup and a rod body, wherein an accommodating groove is formed in the end part of the rod body. The telescopic screw also comprises a plurality of lengthening bars with different lengths; the diameters of the lengthening bars and the diameter of the rod body are identical; bulges which are matched with the accommodating groove are formed on the end parts of the lengthening bars; two clamping structures are symmetrically arranged on the periphery of each bulge; accommodating structures which are matched with the clamping structures are formed in the inner walls of the accommodating groove. The telescopic screw has the beneficial effects that the structural design is ingenious, the length of the screw is conveniently and flexibly adjusted through the matching of the clamping structures and the accommodating structures, and the universality of the screw is improved.

Description

A kind of telescopic type screw rod
Technical field
The utility model relates to a kind of screw rod, is specifically related to a kind of telescopic type screw rod that can adapt to user demand.
Background technique
A base part of commonly using when screw rod is the connections such as engineering goods, screw rod of the prior art is all fixed length, process in advance as required for subsequent use, but, the screw rod of this class fixed length can only be applicable to the connection of a certain given length, and flexibility is poor, in the time that the distance between two parts that screw rod connects need to be adjusted, to change whole screw rod, very loaded down with trivial details.
Model utility content
For solving the deficiencies in the prior art, the telescopic type screw rod that provides a kind of flexibility ratio high is provided the purpose of this utility model.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of telescopic type screw rod, comprises nut and the body of rod, and described rod end has a receiving groove, also comprises: the extension bar that several length are different, and the diameter of described extension bar and end identical with the body of rod forms the projection coordinating with receiving groove; Described protruding periphery is provided with two interface arrangments symmetrically, and the inwall of described receiving groove is formed with the contained structure coordinating with interface arrangment.
The aforementioned body of rod and extension bar are all formed with outside thread.
The inwall of aforementioned receiving groove is formed with many group contained structures, is convenient to extension bar and rotates with respect to the body of rod and then both outside threads are mated.
Aforementioned interface arrangment comprises: spring, prop up the mounting end of spring and stretch out protruding joint end, described spring and mounting end are positioned at protruding inside.
Aforementioned joint end is arc shaped surface.
Aforementioned contained structure is what be obliquely installed near the one side of rod end.
Usefulness of the present utility model is: telescopic type screw rod of the present utility model, structural design is ingenious, by the cooperation of interface arrangment and contained structure, can realize and adjust easily and flexibly spiro rod length, improves the versatility of screw rod itself.
Brief description of the drawings
Fig. 1 is the cross-sectional view of telescopic type screw rod of the present utility model.
The implication of reference character in figure: 1, nut, 2, the body of rod, 3, extension bar, 4, receiving groove, 5, projection, 6, contained structure, 7, interface arrangment, 71, spring, 72, mounting end, 73, joint end.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to Fig. 1, a kind of telescopic type screw rod of the present utility model, comprise nut 1, the agent structure of many extension bars of extension bar 3(3 that the body of rod 2 and several length are different is identical, difference is only the length of extension bar 3, so only show one of them extension bar 3 in figure), extension bar 3 is identical with the diameter of the body of rod 2, wherein, there is a receiving groove 4 in the end of the body of rod 2, and the end of extension bar 3 is formed with the projection 5 coordinating with receiving groove 4, be provided with symmetrically two interface arrangments 7 at protruding 5 peripheries, the inwall of receiving groove 4 is formed with the contained structure 6 coordinating with interface arrangment 7, after interface arrangment 7 coordinates with contained structure 6, extension bar 3 has just firmly linked together with the body of rod 2, use the extension bar 3 of different length, can obtain the screw rod of different length.
Connect for convenient, telescopic type screw rod of the present utility model preferably adopts and is threaded, thereby is all formed with outside thread at the body of rod 2 and extension bar 3.So, adding man-hour, just need to take into full account the position of contained structure 6, after ensureing that interface arrangment 7 coordinates with contained structure 6, the outside thread of the body of rod 2 and extension bar 3 can coordinate to realize connection well.Preferred as one, the inwall of receiving groove 4 is formed with many group contained structures 6, is convenient to extension bar 3 and rotates with respect to the body of rod 2 and then both outside threads are mated, like this, with regard to need to man-hour the position of contained structure 6 not being determined especially adding, improve the flexibility of course of working.
As a kind of concrete structure, interface arrangment 7 comprises: spring 71, prop up the mounting end 72 of spring 71 and stretch out projection 5 joint end 73, spring 71 and mounting end 72 are positioned at the inside of projection 5, joint end 73 is preferably arc shaped surface, contained structure 6 is what be obliquely installed near the one side of the body of rod 2 ends, convenience and flexibility when thereby raising extension bar 3 is connected with the body of rod 2, and stable connection.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
