Abstract
A sleeve barrel of an expansion screw of the utility model relates to a sleeve barrel type component part of the expansion screw. A cylinder sleeve barrel is composed of two long arc-shaped elements. The outer part of the sleeve barrel is coated by a clamping and fixing member. The sleeve barrel of an expansion screw is characterized in that both lateral sides of the long arc-shaped elements are respectively provided with at least one, and more than one tooth. When the two long arc-shaped elements are buckled oppositely, the lateral side teeth are meshed mutually. The sleeve barrel of an expansion screw is characterized in convenient process, high productive efficiency, and low manufacturing cost, and also overcomes the phenomenon of the mutual slippage or overlapping of the two long arc-shaped elements in the prior art, which often occurs. The firmness of a structure is better.
Description
The utility model setscrew sleeve relates to a kind of telescopic setscrew parts.
In existing telescopic setscrew, in response to using the purpose difference, sometimes very high to the sleeve performance requirement, as: require to have high hardness, the good urgent property of opening, simultaneously, good fixedly fastness also will be arranged, for this reason, sleeve hardness is required setscrew sleeve big or that structure is complicated, difficulty of processing is very big on circular sleeve, processing for convenience and improve sleeve in construction with the fixedly fastness of wall, will make by two long arc shape elements than complexity or the bigger setscrew sleeve of hardness structure usually and form the cylinder sleeve, and, two long arc shape elements that do not pin down are mutually fixed with fastener, and fastener can be a buckle, also can be to coat with plastic film, this structure has easy to process, the manufacturing efficiency height, the characteristics that cost of production is low, but, because two long arc shape elements do not pin down mutually, when fixing with fastener or squeezing into sleeve in the cinclides, two long arc shape elements changing of the relative positions or overlapped phenomenon are up and down often arranged, make troubles for production or use.In order to overcome above-mentioned defective, the utility model proposes a kind of new technological scheme.
The purpose of this utility model is: provide a kind of setscrew sleeve of being made up of two long arc shape elements that check and balance, in case the phenomenon of the mutual changing of the relative positions appears in two long arc shape elements when fixing with fastener or sleeve squeezed into cinclides.
The purpose of this utility model can be achieved through the following technical solutions: the setscrew sleeve, form a cylinder sleeve by two long arc shape elements, the sleeve outside is coated by fastener, characteristics are: long arc shape elements on either side limit is respectively provided to less more than one tooth, when two long arc shape elements to fashionable, its side tooth is meshing with each other.When fixing two long arc shape elements with fastener or squeezing into sleeve in the cinclides, prevented that effectively the phenomenon of two long arc shape element changing of the relative positions between the upper and lower from occurring.
On the technique scheme basis, in order to prevent that overlapped phenomenon from appearring in two long arc shape elements, the dual-side drift angle place at two long arc shape element tops of the present utility model outwards routs up, and makes two long arc shape elements to fashionable, forms two axially trips of symmetry at the sleeve top.The utility model has not only changed in original technology because of two long arc shape elements do not pin down the situation that causes the mutual changing of the relative positions mutually, and trip can effectively be fixed in wall, prevents that sleeve from dallying in cinclides.The utility model is on existing long arc shape element basis, finishing structure on two long limits of long arc shape element improves, so the intensity of sleeve and applicability are close with prior art, simultaneously, characteristics easy to process, that manufacturing efficiency is high, cost of production is low that the utility model still has.
Superiority of the present utility model is: not only have characteristics easy to process, that manufacturing efficiency is high, cost of production is low, and, the most important thing is to overcome the upper and lower changing of the relative positions of two long arc shape element normal appearance in using or producing in the prior art or overlapped phenomenon, the steadiness of structure is just good.
Describe in detail below by drawings and Examples.
Accompanying drawing 1, long arc shape elements on either side limit is provided with the utility model structural representation of tooth respectively.
Accompanying drawing 2, the utility model structural representation that the dual-side drift angle place at long arc shape element top outwards routs up.
Embodiment 1, as Fig. 1, long arc shape elements on either side limit is respectively arranged with shown in the utility model structural representation of tooth, the utility model setscrew sleeve, it is an a kind of cylinder sleeve with manhole, trip and bottom two long arc shape elements, 1,2 compositions jaggy, the sleeve outside is coated by plastic film, characteristics are: long arc shape element 1,2 dual-sides be provided with respectively a pair of tooth 11,11 ', 21,21 ', two 1,2 pairs of long arc shape elements are fashionable, its side tooth 11,21 and 11 ', 21 ' be meshing with each other.After two long arc shape elements 1,2 are coated by plastic film 3, two long arc shape elements 1,2 because of between cog 11,21 and 11 ', 21 ' be meshing with each other, in use, do not have the defective of two long arc shape elements, 1, the 2 mutual changing of the relative positions.
Embodiment 2, as Fig. 2, shown in the utility model structural representation that the dual-side drift angle place at a kind of long arc shape element top outwards routs up, the utility model is by two flexible grooves 14,24, and elastic groove 14,24 ends have circular aperture 15,25 long arc shape element 1,2 form a cylinder sleeve, the sleeve outside is coated by plastic film 3, characteristics are: long arc shape element 1,2 dual-sides are provided with tooth 12 respectively, 12 ', 22,22 ', when two long arc shape elements 1,2 pairs fashionable, side tooth 12,12 ', 22,22 ' be meshing with each other, at long arc shape element 1, the dual-side drift angle place at 2 tops outwards routs up 13,13 ', 23,23 ', make two long arc shape elements 1,2 pairs fashionable, forms two axially trips of symmetry at the sleeve top.Because the fixing effect of the utility model trip prevents that effectively sleeve from dallying in cinclides; Simultaneously, because of two long arc shape elements pin down mutually, thereby reach fastening purpose.
Claims (2)
1. setscrew sleeve, form a cylinder sleeve by two long arc shape elements, the sleeve outside is coated by fastener, it is characterized in that: described long arc shape elements on either side limit is respectively provided to less more than one tooth, two long arc shape elements are to fashionable, and its side tooth is meshing with each other.
2. by the described setscrew sleeve of claim 1, it is characterized in that: the dual-side drift angle place at long arc shape element top outwards routs up, and makes two long arc shape elements to fashionable, forms two axially trips of symmetry at the sleeve top.
