Abstract

The utility model relates to a scaling structure of a positioning nut for a support frame. The appropriate places of the front end and the tail end of the screw thread of a positioning nut are respectively provided with a scraping part. The places which are adjacent to thescraping part are respectively provided with a row of holes for debris. When the positioning nut is rotated, dust, dirt and foreign matters which are deposited, piled and clogged between the support frame and the positioning nut are thoroughly loosened through the cutting action of the scraping part. The dust, the dirt and the foreign matters are pushed out of the holes for debris, and the place between the support frame and the positioning nut is smooth.

Description

Scaling structure of positioning nut for support frame

The utility model is a kind of setscrew nut scale removal structure of bracing frame, is used to remove the dust and the dirt that block between bracing frame and setscrew nut, makes and keeps unimpeded state between bracing frame and the setscrew nut.

The grouting of the attic floor that carries out of buildings in general now for the floor that prevents to finalize the design subsides, all must in order to support the weight of residence grouted-aggregate concrete, have much practicality in the bottom support of floor with some round logs or other rod usually.But because the story height of each building is not identical, therefore the round log of this support usefulness or rod often must be adjusted its length along with the variation of its height, thereby make troubles to construction; Metal supporting frames was arranged again afterwards, as shown in Figure 1, was to be formed by combining by a bottom bar 11, a location nut 12, a push rod 13 and a latch 14 substantially.Wherein this setscrew nut 12 is arranged on the bottom bar 11, this push rod 13 then is located in the displacement aperture 111 of establishing in bottom bar 11 nearly places, top by latch 14, latch 14 rests on the setscrew nut 12, so as long as adjust the high and low position of setscrew nut 12 at bottom bar 11 places, can make on the push rod 13 and move or move down, thereby reach the height that increases or shorten this bracing frame.Use more conveniently, need not be considered by its length., regulates on the support of metal the upper-lower position of push rod 13 but though can relying on the rotation of setscrew nut 12, because this bracing frame will use in the construction site after adjusting, and chronic.Go through the invasion and attack of dust, silt particle and other foreign matters around here, the result more or less can fall into and rest on screwing togather in the gap of setscrew nut 12 and bottom bar 11, in the course of time, will result in blockage to setscrew nut 12 after drying is solidified, and can't rotate.In other words, after use a period of time, promptly can lose the function that it regulates displacement, can't use, cause suitable waste.

The purpose of this utility model is just in order to solve weak point of the prior art, and proposed a kind of setscrew nut scale removal structure of bracing frame.Utilize this structure can remove things such as dust between setscrew nut 12 and the bottom bar 11, silt particle, prolong its application life, increase economic efficiency.

The purpose of this utility model is achieved in that

A kind of setscrew nut scale removal structure of bracing frame comprises: a bottom bar, be made into hollow tubular, and its surface, top is the pin thread that forms predetermined number, and the appropriate location on this pin thread offers one group of displacement aperture in correspondence with each other in addition; One location nut is arranged on the set pin thread of this bottom bar, can in time regulate its height stop place according to need; One push rod is located in the hollow bore of this bottom bar slidably, and locates the through hole that the spy offers one group of correspondence below its near; One latch wore set displacement aperture of this bottom bar and the set through hole of this push rod successively, just can rest on this setscrew nut; Be provided with one in each system of appropriate location of the screw thread front end of this setscrew nut and screw thread tail end and strike off portion, and and then this strikes off portion, all offer a chip-removal hole, the bits hole communicates with the external world, when rotating this setscrew nut, can strike off the dissection of portion by this, with deposition, be deposited in the dust, dirt or the foreign matter that block between this bottom bar and this setscrew nut and become flexible up hill and dale, and it be pushed can make between this bracing frame and this setscrew nut by chip-removal hole keep unobstructed state.

The utility model compared with prior art has following advantage: novel structure, simple; Can in time remove things such as dust between bottom bar and the setscrew nut, silt particle, increase the service life; Simple, convenient.

The utility model has 5 width of cloth accompanying drawings, and wherein Fig. 2 is a most preferred embodiment of the present utility model, also can make the accompanying drawing of specification digest.

Fig. 1, be the prior art constructions schematic diagram;

Fig. 2, be stereo appearance figure of the present utility model;

Fig. 3, be sagittal plane of the present utility model sectional view;

Fig. 4, be installed in three-dimensional exploded view on the bracing frame for demonstration of the present utility model;

Fig. 5, be installed in fore-and-aft plane sectional view on the bracing frame for demonstration of the present utility model.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described further:

Most preferred embodiment of the present utility model is shown in each figure, and it mainly provides a kind of setscrew nut scale removal structure of bracing frame, and its component that relate generally to include a bottom bar 2, members such as location nut 3, a push rod 4 and a latch 5; Wherein:

This bottom bar 2 is made into hollow tubular, and there is pin thread 21 on its surface, top, and the appropriate location on this pin thread 21 offers one group of corresponding mutually displacement aperture 22 in addition;

This setscrew nut 3 is to be arranged on the set pin thread 21 of bottom bar 2, can be in time according to need by rotating the height stop place of regulating it.It should be noted that at the screw thread front end of this setscrew nut 3 and the appropriate location of screw thread tail end each system is provided with one and strikes off

portion

31,32, and and then this strikes off

portion

31,32 and all offers a chip-

removal hole

33,34, chip-

removal hole

33,34 communicates with the external world;

This push rod 4 is to be located in slidably in the hollow bore 23 of bottom bar 2, and locates to offer one group of corresponding with it through hole 41 below it is near;

This latch 5 is to wear the set through hole 41 of the set displacement aperture 22 of bottom bar 2 and push rod 4 in regular turn, just can rest on the setscrew nut 3, and making carries out supports push rod 4;

The above is each the correlation position of each associated component assembling of the present utility model and the general introduction of structure.

The utility model is when operation, (or clockwise direction rotates when rotational positioning nut 3, or counter-clockwise direction is rotated), can strike off the dissection of

portion

31,32 by this, dust, dirt or the foreign matter etc. that deposit, be deposited in

bottom bar

2 and 3 obstructions of setscrew nut are become flexible up hill and dale, and will push by chip-

removal hole

33,34 places by the loosening obturator that is produced, can make 3 of bottom bar 2 and setscrew nuts keep unobstructed state.Can make setscrew nut 3 displacement that carries out up or down easily, even service time is of a specified duration again, also rotation that can the overslaugh setscrew nut.

In sum, the simple structure of embodiment of the present utility model, use one to strike off a portion and a chip-removal hole, make the portion of striking off when rotated, the performance dissection, the place, gap that screw thread and screw thread are screwed togather mutually deposits or dust, dirt or the foreign matter etc. of accumulation are able to become flexible up hill and dale, then discharges from chip-removal hole again.Therefore can increase the service life, make operation become simple, convenient.
