Description
Technical field
The utility model is related to the improvement invention of household appliance technical field more particularly to a kind of antitheft big brazier head screws of four square grooves
Improvement invention.
Background technology
Household electrical appliance currently on the market, the screw head of air conditioner housing is all conventional cross cave mostly, is opened with cross
Son is with regard to that can unscrew.And since outdoor machine of air-conditioner is mounted on outdoor, it occur frequently that the phenomenon that plus screw is screwed out.In order to avoid this
The generation of phenomenon, in order not to which screw is allowed to be twisted away by common opener easily, so needing design one kind is unconventional to turn slot.
Utility model content
Technical problem to be solved in the utility model is that overcome the deficiencies of the prior art and provide a kind of four square grooves antitheft big
Brazier head screw.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize：Four square groove of this kind
Antitheft big brazier head screw, includes screw body, it is characterised in that：The head of the screw body is big homalocephalus, and on head
The slot that turns equipped with cubic groove shape, the diameter d of the big homalocephalus is 9.75 ± 0.05mm, and the maximum height h of big homalocephalus is
2.59 ± 0.35mm, the depth a for turning slot accordingly is 1.22-1.66mm, and the width b for turning slot is 2.84mm.
The screw body surface is equipped with trivalent indigo plant white zine dehydrogenation coating, and thickness of coating is at 2.5 μm or more.
The beneficial effects of the utility model are the antitheft big brazier head screws of improved four square groove, by setting cubic groove shape
Turn this irregular twisting mode of slot, solve in the past quick detachable caused by common cross opener twisting mode
Hidden danger, achieved the effect that antitheft.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the left view of the utility model Fig. 1.
Specific embodiment
Attached drawing illustrates the structure of the utility model, further illustrates it in relation to details in conjunction with attached drawing below.The four directions
The antitheft big brazier head screw of slot includes screw body 1, and the head of the screw body 1 is big homalocephalus, and head is equipped with four directions
Groove shape turns slot 2, and the diameter d of the big homalocephalus is 9.75 ± 0.05mm, the maximum height h of big homalocephalus for 2.59 ±
0.35mm turns the depth a of slot 2 as 1.22-1.66mm accordingly, and the width b for turning slot is 2.84mm, the design of this kind of size
It ensure that the intensity that screws for turning slot, and be exclusively used in the installation of outdoor machine of air-conditioner.1 surface of screw body is equipped with trivalent indigo plant white zine
Dehydrogenation coating, and thickness of coating plays good anticorrosion ability at 2.5 μm or more.
Operation principle：The head of bolt body turns the part of slot, is designed to cubic groove shape, in this way can only be by dedicated
Cubic opener can just be unscrewed, and play antitheft effect.
In conclusion the above is only the preferred embodiments of the present utility model only, it is not intended to limit the utility model
Protection domain.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all wrap
Containing being within the protection scope of the utility model.
