Abstract
The utility model discloses a spring pull rod. The spring pull rod comprises a fixed rod and a movable rod, wherein the movable rod consists of a pull rod, a rod head which is connected with the pull rod, a reset spring which is sleeved on the pull rod, and a plug; and the pull rod and the rod head are integrally molded. The fixed connection is integrated cold heading and punching molding. The movable rod and the rod head are integrated, so that the problem that the original rod head is difficult to manufacture and machine is solved, screw slippery is avoided after the rod is stressed, and the connection is reliable; and a cold heading and punching molding mode is adopted, so that the cost of products can be greatly reduced.
Description
Technical field
The utility model relates to a kind of tie-strut, is specifically related to a kind of spring pull bar.
Background technique
The spring pull bar is one of member commonly used on machinery or the building, uses very extensively, can be used on the travel(l)ing rest of automobile, kitchen cabinet, window or medical apparatus.As shown in Figure 1, existing spring pull bar is made up of fixing rod that cooperatively interacts and motion bar, and fixing rod mainly is made up of sleeve pipe 1 and permanent joint 7; Motion bar comprises pull bar 2, the bar head 3 that is connected with pull bar 2 and is socketed in the Returnning spring 4 on the pull bar 2; One end of pull bar 2 links to each other with bar head 3; The other end is successively behind socket setscrew nut 6, Returnning spring 4, the chock plug 5; Again combination is inserted in the sleeve pipe 1 of fixing rod, be connected, make motion bar and fixing rod form telescopic flexible connection by setscrew nut 6 and sleeve pipe 1.
In the existing technology, bar head 3 is to be threaded with pull bar 2, and is not enough below it exists: 1, bar head 3 is made difficulty of processing; 2, the stressed easy stripped thread of screw thread when big of spring pull bar, it is not firm to connect.
The model utility content
Exist to adopt between motion bar and the bar head to existing technology to be threaded, exist the bar head to make processing difficulties, the stressed excessive easy stripped thread of spring pull bar connects illusive deficiency, and the purpose of the utility model provides a kind of firm spring pull bar that connects.
Realize said purpose, the technological scheme that the utility model adopts is following:
A kind of spring pull bar comprises fixing rod and motion bar, and said motion bar is made up of pull bar, the bar head that is connected with pull bar, the Returnning spring and the chock plug that are socketed on the pull bar, and said pull bar and bar are first body formed.
The cold pier punching molding of the first body of said pull bar and bar.
Said bar head is coated with skin, and this skin adopts plastic mode moulding.
Compare existing technology, the utlity model has following beneficial effect:
The utility model is made of one motion bar and bar head, has solved former bar head and has made problem of difficult processing, can not cause stripped thread after stressed, and it is very firm to connect; And adopt cold pier punching molding mode cost lower, can significantly reduce the cost of product.
Description of drawings
Fig. 1 is an existing technology bracing structure schematic representation;
The structural representation of Fig. 2 the utility model spring pull bar.
Wherein, 1 is guide rod, and 2 is pull bar, and 3 is the bar head, and 4 is spring, and 5 is chock plug, and 6 is setscrew nut, and 7 is permanent joint.
Embodiment
Below in conjunction with embodiment the utility model is described further.
As shown in Figure 2, the utility model spring pull bar is made up of fixing rod that cooperatively interacts and motion bar; Fixing rod mainly is made up of sleeve pipe 1 and permanent joint 7; Motion bar comprises pull bar 2, the bar head 3 that is connected with pull bar 2 and is socketed in the Returnning spring 4 on the pull bar 2, and an end of pull bar 2 links to each other with bar head 3, and the other end is successively behind socket setscrew nut 6, the Returnning spring 4; Refill and join spacing chock plug 5; Again combination is inserted in the sleeve pipe 1 of fixing rod, be connected, make motion bar and fixing rod form telescopic flexible connection by setscrew nut 6 and sleeve pipe 1.Setscrew nut 6 all is provided with the assembling screw with permanent joint 7.
The external packets of bar head 3 is covered with skin, and this skin adopts engineering plastics heat packs in injection machine molded, and in bar head 3 was coated on, thickness was suitable.Bar head 3 through plastic moulding after, the shape of its shape and existing technology king-rod head 3 is basic identical, profile is more attractive in appearance.
The utility model motion bar 2 and bar head 3 are made of one solved that former motion bar 2 is threaded and former bar head is made problem of difficult processing, can not cause stripped thread after stressed, and it is very firm to connect.
Need to prove at last; Above embodiment is only in order to technological scheme but not the restriction technologies scheme of explanation the utility model; Although the claimant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technological schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
