Abstract
The utility model discloses it is a kind of assemble easily, the on-slip screw of efficiency of assembling can be improved, including：Shank of screw and the screw cap for being arranged on shank of screw afterbody, screw thread is provided with described shank of screw, arc-shaped transition section is provided with tooth bottom to the central diameter of screw thread.When on-slip screw described in the utility model is with nut check, between the screw thread (external screw thread) on screw thread (internal thread) and described on-slip screw on nut, the active force and reaction force formed on axial direction, so that the crest of the internal thread on nut mutually extrudes with forming radial direction at the arc-shaped transition section of the screw thread of on-slip screw described in the utility model, reached the state of overflowing, so as to be effectively prevented from on-slip screw loosening, the on-slip purpose of on-slip screw is realized.So allowing for the assembling of on-slip screw described in the utility model becomes very easy, substantially increases efficiency of assembling.
Description
Technical field
It the utility model is related to a kind of screw, more particularly to a kind of on-slip screw.
Background technology
At present, traditional locking method is：Directly either processed with on-slip pad at the position that nut contacts with workpiece
The function of screw on-slip and locking is realized into on-slip striped.In actual use, above-mentioned locking method causes assembling
Difficulty is larger, less efficient.
Utility model content
Technical problem to be solved in the utility model is：There is provided it is a kind of assemble easily, the on-slip of efficiency of assembling can be improved
Screw.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of on-slip screw, including：Screw
Bar and the screw cap for being arranged on shank of screw afterbody, screw thread is provided with described shank of screw, is set at tooth bottom to the central diameter of screw thread
There is arc-shaped transition section.
As a kind of preferred scheme, in a kind of described on-slip screw, the arc at tooth bottom to the central diameter of described screw thread
Shape changeover portion is circular arc changeover portion.
As a kind of preferred scheme, in a kind of described on-slip screw, the head of the shank of screw is provided with chamfering；Make
For further preferred scheme, described chamfering is circular arc chamfering.
The beneficial effects of the utility model are：When on-slip screw described in the utility model is with nut check, on nut
The active force formed between screw thread (external screw thread) on screw thread (internal thread) and described on-slip screw on axial direction and reaction
Power so that the crest of the internal thread on nut at the arc-shaped transition section of the screw thread of on-slip screw described in the utility model with forming footpath
To mutually extruding, reaching the state of overflowing, so as to be effectively prevented from on-slip screw loosening, the on-slip mesh of on-slip screw is realized
's.So allowing for the assembling of on-slip screw described in the utility model becomes very easy, substantially increases efficiency of assembling.
Brief description of the drawings
Fig. 1 is the structural representation of on-slip screw described in the utility model.
Fig. 2 is the mplifying structure schematic diagram of D parts in Fig. 1.
Fig. 3 is the dimensional structure diagram of on-slip screw described in the utility model.
Reference in Fig. 1 to Fig. 3 is：1st, shank of screw, 11, circular arc chamfering, 2, screw cap, 3, screw thread, 31, circular arc
Shape changeover portion.
Embodiment
With reference to Fig. 1 to Fig. 3, a kind of specific embodiment of on-slip screw described in the utility model is described in detail.
As shown in figures 1 and 3, a kind of on-slip screw described in the utility model, including：Shank of screw 1 and it is arranged on spiral shell
The screw cap 2 of the afterbody of nail rod 1, screw thread 3 is provided with described shank of screw 1, circular arc is provided with tooth bottom to the central diameter of screw thread 3
Changeover portion 31 -- it is shown in Figure 2；In the present embodiment, the head of the shank of screw 1 is provided with circular arc chamfering 11.
It is well known that in practical application, the head of described shank of screw 1 can also be arranged to the chamfering of other shapes.
Operation principle of the present utility model is：When on-slip screw described in the utility model is with nut check, on nut
Between screw thread 3 (external screw thread) on screw thread (internal thread) and the on-slip screw, the active force and reaction force that are formed on axial direction,
So that the crest of internal thread is mutually extruded with forming radial direction at the circular arc changeover portion 31 of the screw thread 3 of the on-slip screw, reached
The state of overflowing is crossed, so as to be effectively prevented from the on-slip screw loosening, realizes the on-slip purpose of on-slip screw.
In summary, preferred embodiment only of the present utility model, not it is used for limiting the utility model implementation
Scope, the equivalent change that all shape, construction, feature and spirit according to described in the utility model claims scope is made is with repairing
Decorations, all should be included in right of the present utility model.
