Abstract
The utility model relates to a lock screw, including the screw body, the screw body is including the screw cap and the shank of screw that are a body structure, an organic whole is connected with the connecting rod between screw cap and the shank of screw, open flutedly on the connecting rod, the setting of regular polygon structure is personally submitted to shank of screw transversal, the end -to -end connection of shank of screw has buffering portion. The utility model discloses a screw, rational in infrastructure, it is high to connect fastening nature, and the setting of regular polygon structure is personally submitted to shank of screw transversal, has locking anti -drop's effect.
Description
Technical field
The utility model relates to a kind of backing-up screw, belongs to a kind of fastening piece.
Background technique
Screw is the fastening piece for mounting article, and it uses comparatively extensive, usually screw is mounted to fixation and with in the screw of fixture articles, just can implements to fix.The screw generally used in the market, screw rod is generally in cylindrical-shaped structure, and cross section is circular, therefore, the rubbing contact of screw rod and screw can not have stronger obstructive, easily makes screw rotary moveable in spiral hole, easily loosen, affect the stability be fastenedly connected.In addition, in the occasion that some light are more weak, under such as mine, to install or pull down screw inconvenience all very.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 to provide a kind of rational in infrastructure, and anti-loosing effect is good, practical screw.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of backing-up screw, comprise screw body, described screw body comprises screw cap in integrative-structure and screw rod, connecting rod is connected with between described screw cap and screw rod, described connecting rod has groove, the cross section of described screw rod is regular polygon vibrational power flow, and the end of described screw rod is connected with buffer part.
Further technological scheme:
The lower surface of described screw cap is provided with slideproof tooth.
The upper surface of described screw cap is provided with one deck fluorescent layer.
The circular in cross-section vibrational power flow of described buffer part.
Due to the application of technique scheme, the utility model compared with prior art tool has the following advantages:
Screw of the present utility model, rational in infrastructure, connect tightness high, the cross section of screw rod is regular polygon vibrational power flow, has the effect of locking Drop-proof.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
In above accompanying drawing: 1, screw body, 2, screw cap, 3, screw rod, 4, connecting rod, 5, groove, 6, buffer part, 7, slideproof tooth, 8, fluorescent layer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, a kind of backing-up screw of the utility model, comprise screw body 1, described screw body 1 comprises screw cap 2 in integrative-structure and screw rod 3, connecting rod 4 is connected with between described screw cap 2 and screw rod 3, described connecting rod 4 has groove 5, and the cross section of described screw rod 3 is regular polygon vibrational power flow, and the end of described screw rod 3 is connected with buffer part 6.
Preferably, as an embodiment, the lower surface of screw cap 2 is provided with slideproof tooth 7.
Preferably, as another embodiment, the upper surface of screw cap 2 is provided with one deck fluorescent layer 8.
Preferably, as an embodiment, the circular in cross-section vibrational power flow of buffer part 6.
Backing-up screw of the present utility model, connecting rod 4 has groove 5, when screw in use needs line ball, can be inner at groove 5 by wire-wound, line ball is effective, is provided with slideproof tooth 7 at the lower surface of screw cap 2, pressed line is not easily dropped, there is very strong usability.Be provided with one deck fluorescent layer 8 at the upper surface of screw cap 2, when dark, also can see the profile of screw cap clearly, Security and the convenience of operation can be improved.The cross section of screw rod 3 is regular polygon vibrational power flow, and it can increase Peripheric locking power when screw is screwed into screw, has the effect of locking Drop-proof.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvement or replacement, these improve or replace and also should be considered as protection domain of the present utility model.
