Abstract
The utility model discloses a fastening component for machinery, and in particular relates to a novel bolt. The bolt comprises a screw rod and a screw cap fixed on the screw rod; the lower part of the screw rod is provided with a thread; a tool withdrawal groove is formed between the thread part and the part which is not provided with the thread on the screw rod; the tool withdrawal groove is deeper than the thread; the width of the tool withdrawal groove is 2 millimeters; and the outer wall of the screw cap is provided with a hexagonal inner hole. The tool withdrawal groove is formed between the thread part and the part which is not provided with the thread on the screw rod, and the tool withdrawal groove is necessary to be deeper than the thread, so that the bolt can be twisted thoroughly in assembly, and the assembly efficiency is improved; and the outer wall of the screw cap is provided with the hexagonal inner hole, so the bolt is reasonable in design and convenient to assemble.
Description
Technical field
The utility model relates to the secure component that is used for machinery, particularly relates to a kind of novel bolt.
Background technique
As everyone knows, bolt is to be used for fastening link, applies to the assembling of each machine; When the assembling of some key position, need helical thread portion can be screwed into the end completely, traditional bolt comprises threaded screw rod and is fixed on the nut on the screw rod; This structure, in assembling, bolt is used with the part that has internal thread; Because the root of screw thread contacts with part and interferes, and is difficult to accomplish to be screwed into the end, bring a lot of troubles when often giving assembling; Need to change bolt, or need carry out in processing bolt, efficiency of assembling is low.
The model utility content
For solving the problems of the technologies described above, it is a kind of simple in structure that the utility model provides, and make bolt in assembling, can accomplish that one is screwed to the novel bolt at the end.
The novel bolt of the utility model; Comprise screw rod and be fixed on the nut on this screw rod; The bottom of said screw rod is provided with screw thread, it is characterized in that: helical thread portion and be not provided with between the part of screw thread and be provided with tool withdrawal groove on the said screw rod, the degree of depth of said tool withdrawal groove is greater than the degree of depth of said screw thread.
The novel bolt of the utility model, the width of said tool withdrawal groove are 2mm.
The novel bolt of the utility model, said nut outer wall is provided with the hexagonal endoporus.
The novel bolt of the utility model, said screw rod and nut are one-body molded.
Compared with prior art the beneficial effect of the utility model is: at helical thread portion on the screw rod and be not provided with between the part of screw thread and be provided with tool withdrawal groove; The degree of depth of tool withdrawal groove is in assembling, to make bolt in assembling, can accomplish that one is screwed to the end like this greater than the degree of depth of said screw thread; Improve efficiency of assembling; The nut outer wall is provided with the hexagonal endoporus, and is reasonable in design, more convenient assembling.
Description of drawings
Fig. 1 is the plan view of novel bolt in the utility model;
Fig. 2 is the right elevation of novel bolt in the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As depicted in figs. 1 and 2, a kind of novel bolt, screw rod 1 be fixed on the nut 4 on this screw rod 1; The bottom of screw rod 1 is provided with screw thread 2; Screw thread 2 parts and be not provided with between the part of screw thread 2 and be provided with tool withdrawal groove 3 on the screw rod 1, the degree of depth of tool withdrawal groove 3 is greater than the degree of depth of screw thread 2, and the width of tool withdrawal groove 3 is 2mm; Nut 4 outer walls are provided with hexagonal endoporus 5, and screw rod 1 is one-body molded with nut 4.
The utility model is in screw thread 2 parts on the screw rod 1 and be not provided with between the part of screw thread 2 and be provided with tool withdrawal groove 3; In assembling, make bolt in assembling, can accomplish that one is screwed to the end like this, improve efficiency of assembling; The degree of depth of tool withdrawal groove 3 is should be greater than the degree of depth of screw thread 2; Reasonable in design, nut 4 outer walls are provided with hexagonal endoporus 5, more convenient assembling.Screw thread 2 twists operation and accomplishes twisting of tool withdrawal groove 3 simultaneously; Twist and adopt dental lamina rolled thread 2 and roll extrusion tool withdrawal groove 3; Adopt vibrating disk to descend automatically when twisting, can accomplish two procedures simultaneously, improved manufacturing efficiency greatly in one procedure; Size is guaranteed by the dental lamina mould that fully precision and conformity control are better.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
