Abstract
The invention provides a sleeve capable of clamping a bolt and belongs to the technical field of assembly tools. The sleeve comprises a sleeve body, clamping units and fastening units, wherein through holes are formed within the end range of the sleeve body, the clamping units are located in the through holes, one end of each clamping unit extends into a cavity inside the sleeve body, and the other end of each clamping unit is limited outside the sleeve body. The fastening units are located on the sleeve body and make contact with the clamping units so that the clamping units can be camped on the sleeve body. It can be effectively avoided that when the sleeve is used for screwing the bolt in a product, the bolt falls off the sleeve, and because the bolt slides relative to the sleeve, operation is not convenient. Particularly, when the sleeve has to be selected for screwing the bolt into the product in a limited product space, reliability can be effectively guaranteed in the operation process, and production efficiency can be greatly improved.
Description
Technical field
The invention belongs to assembly tool technical field, relate to a kind of bolt collar.
Background technology
Bolt tightening is the assembling of various engineering goods parts, fastening major way, for ensureing that the phenomenon of sliding tooth, damaged screw does not appear in bolt in rundown process, require the first step of bolts assemblies be with the instrument such as hand or sleeve by the slight bolt several teeth of screw that are screwed in advance, re-use equipment or the instrument fast screwing downs such as pneumatic, electric wrench.But along with the development of technical merit, the structure of engineering goods more and more reassembles, more and more compacter, cause bolt installing space around more and more narrower and small, part bolt cannot be screwed into screw in advance with finger, must use the instruments such as sleeve to be screwed in advance, and the problem of bringing is that bolt always drops or bolt can not be screwed into screw smoothly, cause installation time to extend, production efficiency reduces greatly.
Summary of the invention
The object of the present invention is to provide a kind of sleeve that prevents that bolt from dropping.
In order to achieve the above object, solution of the present invention is:
Sleeve that can fishbolt, comprises sleeve body, clamping unit and fastening unit; Wherein, within the scope of the end of described sleeve body, comprise through hole, described clamping unit is arranged in described through hole, and one end extend in the internal cavity of described sleeve body and the other end is limited in the outside of described sleeve body; Described fastening unit is positioned in described sleeve body, contacts that with described clamping unit described clamping unit is clamped in described sleeve body.
Described through hole is conical through-hole, and described clamping unit is pellet part.
Described pellet part is steel ball.
Described sleeve comprises two described steel balls and two described through holes.
Described two diameters that steel ball line is described sleeve cross section.
Or described sleeve comprises a described steel ball and a described through hole.
Gap between described clamping unit one end in the internal cavity of described sleeve body is consistent with the head sizes of bolt to be clamped, or the head sizes of gap between one end and the inwall of described sleeve body of described clamping unit in the internal cavity of described sleeve body and bolt to be clamped is consistent.
In described sleeve body, comprise the jump-ring slot through described through hole, described fastening unit is jump ring, and described jump ring is arranged in described jump-ring slot.
The outer ring of described jump-ring slot and a cross section of described sleeve body is concentric circles.
Owing to adopting such scheme, the invention has the beneficial effects as follows: the sleeve that the present invention can fishbolt can clamp bolt to be operated therein, prevent from being screwed into when operation problem of dropping from sleeve of bolt and the unhandy problem causing because bolt slides with respect to sleeve using sleeve to carry out bolt, particularly limited and must select sleeve to be screwed into bolt time in product space, the present invention can effectively ensure the reliability of this operating process, has greatly improved production efficiency.Meanwhile, the present invention also has advantages of that enforcement is simple and easy to operate.

Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
The present invention proposes a kind of sleeve that can fishbolt, this sleeve comprises sleeve body 1, steel ball 2 and jump ring 3.The end of sleeve body 1 comprises conical through-hole 5 and passes through the jump-ring slot 4 of conical through-hole 5, wherein jump-ring slot 4 is concentric circles with the outer ring of a cross section of sleeve body 1, be the structural representation of this sleeve body 1 as shown in Figure 1a, Fig. 1 b is depicted as the cutaway view of Fig. 1 a at A-A visual angle.
The present embodiment comprises that two conical through-holes 5 and 2, two steel balls 2 of two steel balls lay respectively in two conical through-holes 5, and its one end extend in the internal cavity of sleeve body 1, and the other end is limited in the outside of sleeve body 1 all the time.The line of two steel balls 2 is the diameter of certain cross section of sleeve body 1, and two steel balls 2 are arranged symmetrically with about the axis of described sleeve body.Jump ring 3 is arranged in jump-ring slot 4, blocks steel ball 2, by regulating the elastic clamping power of jump ring 3 to steel ball 2, steel ball 2 is clamped between conical through-hole 5 and jump ring 3.Fig. 2 a is depicted as the structural representation of this sleeve, and Fig. 2 b is the cutaway view of Fig. 2 a at B-B visual angle.In order to realize fishbolt, the gap between two steel balls 2 one end in the internal cavity of sleeve body is consistent with the head sizes of bolt to be clamped.
This can fishbolt sleeve in use, bolt is pushed between the one end in the internal cavity that two steel balls 2 stretch into sleeve body, bolt is clamped in this sleeve by these two steel balls 2, can tight a bolt by operating this sleeve, the problem of having avoided bolt to drop from sleeve, make this operation tighting a bolt more simple simultaneously, be easy to control.
The present invention is not limited to above-described embodiment, and for example in above-described embodiment, steel ball 2 can be replaced by other clamping unit, and jump ring also can be replaced by other fastening unit; And in sleeve dimensions hour, steel ball and through hole also can only have one, now this sleeve is that bolt is pushed between steel ball one end and the inwall of sleeve body in the internal cavity of sleeve body in use, bolt is clamped in sleeve by steel ball and sleeve body, and now the head sizes of the gap between one end and the inwall of sleeve body of steel ball in the internal cavity of sleeve body and bolt to be clamped is consistent.
The present invention can fishbolt sleeve bolt to be operated can be clamped therein, prevent from being screwed into when operation problem of dropping from sleeve of bolt and the unhandy problem causing because bolt slides with respect to sleeve using sleeve to carry out bolt, particularly must select sleeve to be screwed into bolt at engineering goods limited space time, the present invention can effectively ensure the reliability of this operating process, has greatly improved production efficiency.Meanwhile, the present invention also has advantages of that enforcement is simple and easy to operate.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.Person skilled in the art obviously can easily make various amendments to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not departing from improvement and the amendment that category of the present invention makes all should be within protection scope of the present invention.
