Abstract
The utility model relates to a kind of two fixing bolt, comprise bolt head and threaded stem, the center of threaded stem is provided with the female groove of band, groove internal thread is connected with externally threaded internal thread bar, the bottom of internal thread bar is tapering head, and the top of internal thread bar passes the top of bolt head and is connected with inner bolt head, with the inner groovy mated with inner bolt head shapes on bolt head, the length of internal thread bar is longer than the length of threaded stem, and the height of inner bolt head is lower than the height of bolt head.The utility model has the advantages that: internal thread bar can slide by upper and lower screw thread in the groove of threaded stem, and the length of internal thread bar is longer than the length of threaded stem, and therefore, internal thread bar can carry out secondary to be fixed, and adds the soundness of bolt.
Description
Technical field
The utility model relates to a kind of bolt, particularly relates to a kind of two fixing bolt, belongs to standard piece and manufacture field.
Background technique
Bolt is widely used by people as the fastening piece of a kind of installation and fixing section bar, the bolt kind used in present assembly process is a lot, but be the structural design adopting bolt standard piece in general mostly, each bolt that is in section bar installation is all apply with the form of standard piece; In the use of reality, find that there is following deficiency: bolt easily gets loose and causes fixing loosely in the process of fixation fastener.Therefore, a kind of new technological scheme should be provided to solve the problem.
Summary of the invention
The purpose of this utility model is: provide a kind of two fixing bolt.
For achieving the above object, the technical solution adopted in the utility model is: a kind of two fixing bolt, comprise bolt head and threaded stem, the center of threaded stem is provided with the female groove of band, groove internal thread is connected with externally threaded internal thread bar, the bottom of internal thread bar is tapering head, and the top of internal thread bar passes the top of bolt head and is connected with inner bolt head, with the inner groovy mated with inner bolt head shapes on bolt head.
The length of internal thread bar is longer than the length of threaded stem.
The height of inner bolt head is lower than the height of bolt head.
Due to the application of technique scheme, the utility model compared with prior art tool has the following advantages:
Internal thread bar can slide by upper and lower screw thread in the groove of threaded stem, and the length of internal thread bar is longer than the length of threaded stem, and therefore, internal thread bar can carry out secondary to be fixed, and adds the soundness of bolt.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment one structural representation.
Accompanying drawing 2 is the plan view of the utility model embodiment one.
In above accompanying drawing: 1-bolt head, 2-threaded stem, 3-internal thread, 4-groove, 5-outside thread, 6-internal thread bar, 7-inner bolt head, 8-inner groovy.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment one:
As shown in Figure 1 to Figure 2, a kind of two fixing bolt of the utility model, comprise bolt head 1 and threaded stem 2, the center of threaded stem 2 is provided with the groove 4 with internal thread 3, groove 4 internal thread 3 is connected with the internal thread bar 6 with outside thread 5, the bottom of internal thread bar 6 is tapering head, and the top of internal thread bar 6 passes the top of bolt head 1 and is connected with inner bolt head 7, with the inner groovy 8 with inner bolt head 7 form fit on bolt head 1.
The length of internal thread bar 6 is longer than the length of threaded stem 2.
The height of inner bolt head 7 is lower than the height of bolt head 1.
Internal thread bar 6 can slide by upper and lower screw thread in the groove 3 of threaded stem 2, and the length of internal thread bar 6 is longer than the length of threaded stem 2, and therefore, internal thread bar 6 can carry out secondary to be fixed, and adds the soundness of bolt.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
