Abstract

The utility model discloses a fastening connection piece which comprises a bolt and a bush, wherein the bush is connected to a screw rod of the bolt in a sleeved mode. At least two clamping blocks are arranged on the bush in a stamping mode, and the clamping blocks protrude out of the inner wall of the bush and are located at the same height. The fastening connection piece solves the problem that in the prior art, a bush and a bolt can be separated easily, the at least two clamping blocks which are arranged on the bush in the stamping mode and protrude out of the inner wall of the bush, the protruding clamping blocks are used for limiting the bush, and separation of the bush and the bolt is avoided.

Description

A kind of fastening connection piece
Technical field
The utility model has related to a kind of fastening connection piece, belongs to the Machining Technology field.
Background technique
Fastening connection piece is widely used in connection and the application between the material of different qualities.In order to make the connection better effects if of fastening connection piece, usually on the screw rod of fastening connection piece, be set with lining, and this lining normally before fastening connection piece dispatches from the factory with regard to supporting being arranged on screw rod, so that the later stage is more convenient while using.But, for can being overlapped, lining installs on screw rod, usually the internal diameter of lining is designed to consistent with screw flight section width, and lining directly is sleeved on screw rod, this mounting type is in the transportation process of fastening connection piece, owing to jolting, rocking, be easy to make lining and screw rod to be separated, cause fastening connection piece in use, need to reselect suitable lining and be coordinated completely, cause installation efficiency low.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of fastening connection piece, can effectively avoid separating of sleeve pipe and bolt, is convenient to the installation of fastening connection piece, has improved installation efficiency.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of fastening connection piece, comprise bolt and be socketed in the lining on the screw rod of described bolt, described lining upper punch press be formed with at least two protrusions and described lining inwall, the fixture block in sustained height.
Aforesaid a kind of fastening connection piece is characterized in that: the angle between described fixture block and horizontal plane is 30 °-60 °.
Aforesaid a kind of fastening connection piece is characterized in that: the distance of described fixture block and lining upper surface is the 1/4-1/3 of lining total height.
Aforesaid a kind of fastening connection piece is characterized in that: the quantity of described fixture block is two, is symmetrically distributed on the contour of described lining.
Aforesaid a kind of fastening connection piece is characterized in that: the quantity of described fixture block is three, equidistantly is distributed on the contour of described lining.
Aforesaid a kind of fastening connection piece is characterized in that: the quantity of described fixture block is four, equidistantly is distributed on the contour of described lining.
The beneficial effects of the utility model are: become the fixture block of at least two protrusions and lining inwall by the body upper punch swaging at lining, utilize the fixture block of protrusion to carry out lining spacing, avoid separating of lining and bolt.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fastening connection piece of the utility model;
Fig. 2 is the plan view of the utility model the first embodiment's lining;
Fig. 3 is the plan view of the utility model the second embodiment's lining;
Fig. 4 is the plan view of the utility model the 3rd embodiment's lining.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of fastening connection piece, comprise bolt 1 and be socketed in the lining 2 on the screw rod of described bolt 1, described lining 2 upper punches press be formed with at least two protrusions and described lining 2 inwalls, the fixture block in sustained height 21.Become the fixture block 21 of at least two protrusions and lining inwall by the body upper punch swaging at lining 2, utilize 21 pairs of linings of fixture block 2 of protrusion to carry out spacing, avoid separating of lining 2 and bolt 1.
Through repetition test, the angle between fixture block 21 and horizontal plane is 30 °-60 °, and fixture block 21 is the 1/4-1/3 of lining 2 total heights with the distance of lining 2 upper surfaces, best results.
Embodiment 1
As shown in Figure 2, the quantity of fixture block 21 is two, is symmetrically distributed on the contour of described lining 2, and the 21 pairs of linings of fixture block 2 that utilize to protrude carry out spacing, avoids separating of lining 2 and bolt 1.
Embodiment 2
As shown in Figure 3, the quantity of fixture block 21 is three, equidistantly is distributed on the contour of described lining 2, and the 21 pairs of linings of fixture block 2 that utilize to protrude carry out spacing, avoids separating of lining 2 and bolt 1.
Embodiment 3
As shown in Figure 4, the quantity of fixture block 21 is four, equidistantly is distributed on the contour of described lining 2, and the 21 pairs of linings of fixture block 2 that utilize to protrude carry out spacing, avoids separating of lining 2 and bolt 1.
In sum, a kind of fastening connection piece that the utility model provides, can effectively avoid separating of sleeve pipe and bolt, is convenient to the installation of fastening connection piece, improved installation efficiency.
Above demonstration and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
