Abstract
The utility model discloses a hexagon screw with anti-slip teeth, mainly comprising a screw head and a screw rod. The screw head is connected with the screw rod, and has six side walls to form a hexagon. The screw rod is provided with threads. At least one side wall is provided with a groove. The groove can provide additional force applying point to other tools, and the hexagon screw which has tooth slipping and cannot be locked by the wrench is started. When the tooth slips, the hexagon screw can be normally detached, so the utility model avoids the traditional condition that the detachment is completed through cutting the screw rod, is labor-saving and convenient, and has no damage to equipment. As the appearance is completely matched with that of the traditional hexagon screw, the utility model can be universal with the traditional screw, and does not affect the design and use.
Description
Technical field
The utility model relates to a kind of screw, particularly a kind of anti-skidding tooth hex screw.
Background technique
Screw is that mechanical field locking element, especially hex screw commonly used are seen everywhere in people's life especially.Existing hex screw mainly comprises screw head and screw rod, and screw head is connected with screw rod, and screw head has six sidewalls, becomes regular hexagon, operates screw by monkey spanner or hexagon wrench during use.In productive life; run into the situation that screw gets rusty with age through regular meeting; the sidewall corner angle are become fragile, or repeatedly turning in the process impairedly and cause sliding tooth, make that wrench can't the locking screw ailhead and cause and shirk difficulty; this moment is not owing to there is other Point of Strength; make various tool all can't operate, run into this situation, can only cut off screw rod usually and finish dismounting it; waste time and energy, and damage equipment easily.
Summary of the invention
The purpose of this utility model is that provide for the deficiency that solves above-mentioned technology a kind of has other Point of Strength, can be by the anti-skidding tooth hex screw of other instrument dismounting.
In order to achieve the above object, the anti-skidding tooth hex screw that the utility model is designed, it mainly comprises screw head and screw rod, screw head is connected with screw rod, and screw head has six sidewalls, becomes regular hexagon, screw rod is provided with screw thread, and described at least one sidewall is provided with groove.This groove can be other instruments extra Point of Strength is provided, and is used to start sliding tooth and can't be with the hex screw of wrench locking.
As preferably, described groove is arranged on face to face two sidewalls, can adopt symmetric force that screw head is operated thus.
As preferably, all be provided with groove on each sidewall.
As preferably, described groove is a wedge slot.
As preferably, described groove runs through whole sidewall in the axial direction.
As preferably, described groove runs through whole sidewall diametrically, forms groove.
The resulting anti-skidding tooth hex screw of the utility model when screw head is slided tooth, also can normally be dismantled, and has avoided can only adopting the situation that screw rod is finished dismounting of cutting off in the past, more laborsaving convenience, and do not damage equipment.And mate fully with existing hex screw on the profile, can be general with existing screw, do not influence design and use.

Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, 2, the anti-skidding tooth hex screw that present embodiment is described, it mainly comprises screw head 1 and screw rod 2, screw head 1 is connected with screw rod 2, and screw head 1 has six sidewalls 3, becomes regular hexagon, screw rod 2 is provided with screw thread, and one of them sidewall 3 is provided with groove 4.Groove 4 is a wedge slot.Described wedge slot refers to the groove that one side is formed for slope 6 for straight wall 5 one sides.The set-up mode of straight wall 5 is the direction settings along screw disassembling, makes that straight wall 5 can provide a painstaking platform, can dismantle by the mode that pole adding knocks when screw head 1 is slided tooth.
As shown in Figure 3, the anti-skidding tooth hex screw that present embodiment is described all is provided with wedge slot on six sidewalls 3 as different from Example 1.Make when knocking dismounting more convenient, stressed more even.
As shown in Figure 4, the anti-skidding tooth hex screw that present embodiment is described, wherein two aspectant sidewalls 3 are provided with groove 4 as different from Example 1.Groove 4 is blind groove.This groove 4 can be anchor clamps provides fulcrum.
As shown in Figure 5, the anti-skidding tooth hex screw that present embodiment is described, groove 4 runs through whole sidewall 3 diametrically as different from Example 3, forms groove.Two-way extension bar can be set in groove 4, can be by the extension bar screw of outwarding winding.Also can adopt other instrument that is fit to dismountings.
Embodiment 5
As shown in Figure 6, the anti-skidding tooth hex screw that present embodiment is described, described as different from Example 3 groove 4 runs through whole sidewall 3 in the axial direction, can embed poles at groove 4, by promoting the pole screw of outwarding winding.
