Abstract
The invention discloses an extension tube bundle capable of increasing the clamping force. The extension tube bundle comprises a tube bundle body and a sleeve, wherein cylindrical space is formed along the length direction of the sleeve; a flange is arranged on the outer wall of the sleeve; a groove is formed in the upper part of the flange; a clamping piece is arranged in the groove; the clamping piece is adjacent to the cylindrical space and is provided with a joint end jointed with the sleeve; the flange is formed from the two ends of the clamping piece along the tangential direction; and an empty slot connected with the cylindrical space is formed in the position, close to the bottom of the sleeve, of the flange below the clamping piece. The extension tube bundle can achieve the effect of effectively preventing extension tubes from falling off and has the effects of reinforcing the extension tube clamping strength and stability, prolonging the service lives of the extension tubes and reducing the use cost.
Description
Technical field
The present invention relates to a kind of telescopic pipe, particularly relate to the tube bank of a kind of telescopic pipe.
Background technique
Current telescopic pipe may be used for clothes hanger, flexible support body etc., for the extensive articles for use of family's five metals application, existing telescopic pipe comprises the compositions such as tube bank, intermediate plate, Rotational Cylindrical and salient point, existing salient point quite easily weares and teares, thus the distance causing Rotational Cylindrical compressing salient point passing intermediate plate to inside contract is inadequate, causes the clipping power of telescopic pipe not enough, telescopic pipe has the risk of slippage, cannot meet usage requirement.
Therefore those skilled in the art are devoted to develop a kind of telescopic pipe tube bank that steady in a long-term can provide folder Shu Li.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of telescopic pipe tube bank that steady in a long-term can provide folder Shu Li.
For achieving the above object, the invention provides a kind of telescopic pipe tube bank that can improve clamping force, comprise tube bank body and sleeve pipe, the length direction along described sleeve pipe offers cylindrical space;
Described sleeve outer wall is provided with flange, and the top of described flange offers groove, is provided with intermediate plate in described groove, and described intermediate plate is close to described cylindrical space and has the joint end engaging described sleeve pipe; Described flange is tangentially formed by described intermediate plate two ends;
Be provided with in described groove and be forced to plane away from the open end of described binding end and between described joint end and this open end, in described groove, be provided with Rotational Cylindrical, and through latch through Rotational Cylindrical and described flange pivot joint;
Described Rotational Cylindrical side convexes to form extruded strip.
The invention has the beneficial effects as follows: the present invention can effectively prevent telescopic pipe from coming off, strengthen the strength and stability performance of clipping telescopic pipe, extend the working life of telescopic pipe, reduce user cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the backsight structural representation of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As Figure 1-Figure 2, a kind of telescopic pipe tube bank that can improve clamping force, comprise tube bank body 10 and sleeve pipe 20, the length direction along sleeve pipe 20 offers cylindrical space 21;
Sleeve pipe 20 outer wall is provided with flange 22, and this flange 22 can improve overall construction intensity.The top of flange 22 offers groove, is provided with intermediate plate 30 in groove, and intermediate plate 30 is close to cylindrical space 21 and has the joint end 31 of abutment sleeve 20; Flange 22 is tangentially formed by intermediate plate 30 two ends; Intermediate plate 30 lower bead 22 is located to arrange the dead slot 23 be connected with cylindrical space 21 bottom sleeve pipe 20, and this dead slot 23 has saved manufacture cost.
Be provided with away from the open end 32 of binding end 31 in groove and be forced to plane 33 between joint end 31 and this open end 32, Rotational Cylindrical 40 is provided with in groove, Rotational Cylindrical 40 is arranged between two flanges 22, and through latch 50 through Rotational Cylindrical 40 and flange 22 pivot joint; Conveniently, flange 22 is for extend to bottom this sleeve pipe 20 down.
Rotational Cylindrical 40 side convexes to form extruded strip 41; Rotational Cylindrical 40 extends outwardly to be provided with and pulls out plate 42, pulls out plate 42 end and has turn of bilge 43; The open end 32 of intermediate plate 30 is provided with edge clipping 34, and this edge clipping 34 increases the intensity of the body 10 of intermediate plate 30 clipping telescopic pipe.The present invention utilizes extruded strip 41 to instead of original bump structure, utilize extruded strip 41 to oppress and be forced to plane 33, to increase the area of contact being forced to plane 33, avoid extruded strip 41 to damage because of Long-Time Service, when Rotational Cylindrical 40 through extruded strip 41 oppress this be forced to plane 33 allow intermediate plate 30 invade cylindrical space 21 time, that can guarantee intermediate plate 30 inside contracts distance enough, ensure that the power of intermediate plate 30 clipping telescopic pipe when invading cylindrical space 21 is enough, effectively avoid telescopic pipe and have the risk come off, add the strength and stability of intermediate plate 30 clipping telescopic pipe.
Sleeve pipe 3 and intermediate plate 30 are formed in one structure.
Rotational Cylindrical 40 rotate relative to sleeve pipe 20 and have through this extruded strip 41 compressing be forced to plane 33, intermediate plate 30 is allowed to invade this cylindrical space 21, Rotational Cylindrical 40 can stretch out and pull out plate 42, this pulls out plate 42 and can be used for user to control the rotation of Rotational Cylindrical 40, turn of bilge 43 can promote antiskid property, is convenient to convenient the rotating Rotational Cylindrical 40 of user.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
