The pressing nail anti-loose structure is simple in structure and good in anti-loose effect.
Description
Technical field
The utility model belongs to the transformer technology field, relates to a kind of pressure nail anti-loose structure, is specially adapted in the transformer body of oil immersed transformer.
Background technique
The axial compression of oil immersed transformer device body generally adopts presses the oncomelania bolt to compress, loosening in order to guarantee to press the oncomelania bolt, usually adopts belleville spring to add the structure of lock nut locking, and there is following problem in this structure: 1. cost is high; 2. the pressure oncomelania bolt of upper part of transformer body minute position is because of the stopping of lead-in wire, support etc., the operating space is little, so that the fastening difficulty of lock nut is fastening unreliable, has hidden danger of quality; 3. affect the magnetic shielding assembling of folder.
The model utility content
Technical problem to be solved in the utility model is for the above-mentioned problems in the prior art, provides a kind of simple in structure and anti-loosing effect to press preferably the nail anti-loose structure.
The technological scheme that solution the utility model technical problem adopts is that this pressure nail anti-loose structure comprises the fixed plate that can be fixed on the pressure nail nut, has the anti-porosity that clamps for the fastening end that will press nail on the described fixed plate.
Preferably, described fixed plate is L shaped bent plate, and an end of described L shaped bent plate is connected with described pressure nail nut, and described anti-porosity is arranged on the other end of L shaped bent plate.
More preferably, also include fixed mechanism in this anti-loose structure, described fixed mechanism is used for described L shaped bent plate is connected with described pressure nail nut.
Preferably, described fixed mechanism comprises the hole link, described L shaped bent plate has fixed hole with an end of pressing nail nut to be connected, press on the nail nut and have corresponding aperture, described hole link is used for connecting described fixed hole and corresponding aperture, when by the hole link fixed hole and corresponding aperture being linked together, the fastening end of described pressure nail can be in the anti-porosity of described fixed plate just.
Wherein, described hole link can adopt fixing bolt.
Preferably, the sectional shape of the fastening end of described pressure nail is n limit shape, and the shape of described anti-porosity is suitable with the sectional shape of the fastening end of pressing nail
Preferably, described fixed plate adopts steel plate to make.
The utility model presses the nail anti-loose structure to have the anti-porosity suitable with the sectional shape of the fastening end of pressing nail, when the end with fixed plate is fixed on the pressure nail nut, just can make and press the fastening end of nail to be in the described anti-porosity, be that locking borehole jack is located at outside the fastening end of pressing nail, so that press nail to rotate, thereby can play preferably locking effect, in terms of existing technologies Effective Raise anti-loosing effect.That this pressure nail anti-loose structure also has is simple in structure, the advantage such as little takes up space.By this anti-loose structure, the problems such as operating difficulties that cause because of narrow space have been solved, thereby can avoid the problem that folder magnetic shielding and dish spring and thin nut interfere in the existing anti-loose structure, also reduce operator's labor intensity and reduced manufacture cost simultaneously.

Embodiment
For making those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of pressure nail anti-loose structure comprises being fixed on the fixed plate of pressing on the nail nut, has the anti-porosity that clamps for the fastening end that will press nail on the described fixed plate.
Embodiment 1:
As Figure 1-3, in the present embodiment, press nail nut 4 to be welded on the folder web 5, have the tapped hole adaptive with the shape of pressing nail 2 on the Vertical direction of pressure nail nut 4, described pressure nail 2 is arranged in the described tapped hole.It is loosening that pressure nail anti-loose structure in the present embodiment is used for preventing from pressing nail 2 to occur.
In the present embodiment, this pressure nail anti-loose structure comprises fixed plate and fixed mechanism.Shown in Fig. 4,5, described fixed plate adopts L shaped bent plate 1, one end of described L shaped bent plate (vertically arranges, be vertical end) can be connected with pressing nail nut 4 by described fixed mechanism, have the anti-porosity that clamps for the fastening end that will press nail on the other end of L shaped bent plate 1 (along continuous straight runs setting, i.e. horizontal ends).In the present embodiment, pressing the sectional shape of the fastening end of nail is regular hexagon, corresponding, and the shape of the anti-porosity on the L shaped bent plate adopts the regular hexagon suitable with the sectional shape of the fastening end of pressing nail.
Wherein, described fixed mechanism comprises the hole link.In the present embodiment, described hole link adopts fixing bolt 3.Have fixed hole on L shaped bent plate 1 and the vertical end of pressing nail nut 4 to be connected, press have on the nail nut 4 can be corresponding with described fixed hole corresponding aperture, described corresponding aperture along continuous straight runs extends, described fixing bolt 3 is used for connecting described fixed hole and corresponding aperture, when by fixing bolt 3 fixed hole and corresponding aperture being linked together, the fastening end of described pressure nail can be in the anti-porosity of fixed plate just.
In the present embodiment, described fixed plate adopts sheet metal to make.
At first, locking borehole jack on the horizontal ends of L shaped bent plate 1 is being pressed on the fastening end of following closely, by fixing bolt 3 corresponding aperture on the fixed hole on the vertical end of L shaped bent plate 1 and the pressure nail nut 4 is connected again, press on the nail nut 4 thereby the vertical end of L shaped bent plate can be fixed on, with locking to pressing nail 2 to carry out.
Embodiment 2:
Press the nail anti-loose structure to be from embodiment 1 difference in the present embodiment: the shape of the anti-porosity on the fixed plate is different.
In the present embodiment, be octagon owing to pressing the sectional shape of the fastening end of nail, corresponding, the shape of the anti-porosity on the L shaped bent plate adopts the octagon suitable with the sectional shape of the fastening end of pressing nail.
Other structures in the present embodiment are all identical with embodiment 1, repeat no more here.
Be understandable that, above mode of execution only is the illustrative embodiments that adopts for principle of the present utility model is described, yet the utility model is not limited to this.For those skilled in the art, in the situation that do not break away from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement also are considered as protection domain of the present utility model.
