Abstract
The utility model provides a tie rod convenient to dismount and mount. The tie rod comprises an inner jackstay and revolving rods, wherein the two ends of the inner jackstay are provided with external threads, and the revolving rods are provided with collar nuts matched with the external threads of the inner jackstay; the external threads of the inner jackstay are sleeved with positioning plugs; the positioning plugs comprise plastic plug bodies and polygonal nuts embedded in the plastic plug bodies; the polygonal nuts are matched with the external threads of the inner jackstay. According to the tie rod, due to the facts that the external threads of the inner jackstay are sleeved with the positioning plugs, and the positioning plugs comprise the plastic plug bodies and the polygonal nuts embedded in the plastic plug bodies, not only are the requirements of the plugs for plastic materials satisfied, but also positioning can be performed on the plugs; besides, the structure is simpler.
Description
Technical field
The utility model relates to apparatus for building, its be specifically related to a kind of easy disassembly to pull bar.
Background technology
Existing pull bar is mostly to non-disconnectable formula, during use, mostly need to cuts away and expose the unnecessary to pull bar of wall part, can cause so a large amount of wastes of material.Also have a kind of detachable pulling rod, comprise internal overarm support and all bull sticks of bolt with it, internal overarm support is arranged with Plastic cap outward, adopts the blocked ear that is arranged on internal overarm support and pad to carry out Plastic cap spacing, and the parts that this limit method adopts are more, more loaded down with trivial details.
Utility model content
The purpose of this utility model is to solve the problem that prior art exists, provide a kind of easy disassembly to pull bar, external screw thread at internal overarm support is arranged with positioning plug head outward, this location plug comprises Plastic cap body and embeds the intrinsic polygonal nut of this Plastic cap, both met the requirement of plug to plastic material, can position plug again, this structure is simpler.
In order to reach above-mentioned technical purpose, the utility model by the following technical solutions:
A kind of easy disassembly to pull bar, comprise all bull sticks that two ends are provided with externally threaded internal overarm support and comprise the collar nut matching with the external screw thread of this internal overarm support, the external screw thread of described internal overarm support is arranged with positioning plug head outward, described location plug comprises Plastic cap body and embeds the intrinsic polygonal nut of described Plastic cap, and described polygonal nut matches with the external screw thread of described internal overarm support.
As such scheme preferably, the length of described polygonal nut is less than the length of described Plastic cap body, the length sum of the length of described polygonal nut and the collar nut of all bull sticks and described Plastic cap body equal in length.
As such scheme preferably, described polygonal nut is hex nut.
Owing to having said structure, the utility model has the following advantages compared to existing technology:
1, a kind of easy disassembly that the utility model provides to pull bar, external screw thread at internal overarm support is arranged with positioning plug head outward, this location plug comprises Plastic cap body and embeds the intrinsic polygonal nut of this Plastic cap, both met the requirement of plug to plastic material, can position plug again, this structure is simpler.
2, the length sum of the length of polygonal nut and the collar nut of all bull sticks and Plastic cap body is equal in length, makes the whole structure to pull bar compacter.
3, adopt hex nut to embed in Plastic cap body, stability is stronger, radial rolling can not occur.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation to pull bar of a kind of easy disassembly of the present utility model;
Fig. 2 is the A-A sectional view in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, shown in 2, the utility model provide a kind of easy disassembly to pull bar, comprise all bull sticks 2 that two ends are provided with externally threaded internal overarm support 1 and comprise the collar nut 3 matching with the external screw thread of this internal overarm support, the external screw thread of described internal overarm support 1 is arranged with positioning plug head 4 outward, described location plug 4 comprises Plastic cap body 41 and embeds the intrinsic hex nut 42 of described Plastic cap, described hex nut 42 matches with the external screw thread of described internal overarm support 1, the length of described hex nut 42 is less than the length of described Plastic cap body 41, the described length of hex nut 42 and the length sum of the collar nut of all bull sticks 3 and described Plastic cap body 41 equal in length, that the externally threaded length at internal overarm support two ends can be established with Plastic cap body is equal in length.
A kind of easy disassembly that the utility model provides to pull bar, external screw thread at internal overarm support is arranged with positioning plug head outward, this location plug comprises Plastic cap body and embeds the intrinsic polygonal nut of this Plastic cap, both met the requirement of plug to plastic material, can position plug again, this structure is simpler; The length sum of the length of polygonal nut and the collar nut of all bull sticks and Plastic cap body equal in length, makes the whole structure to pull bar compacter; Adopt hex nut to embed in Plastic cap body, stability is stronger, radial rolling can not occur.
One end of the non junction nut of described all bull sticks 2 be provided with T capable in silk tooth 5, on described all bull sticks 2, be provided with groove 6, when tightening and dismantling by instrument, the contact surface of increase instrument and all bull sticks 2, more laborsaving convenience.
The center of described internal overarm support 1 can also be provided with flashing 7, can be under water.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
