Description

The structure of improved level meter magnetic holder

The utility model relates to a kind of structure of improved level meter magnetic holder, be fit to building industry and civil engineering work industry, especially refer to measure the magnetizable metal material of tool, can promptly be provided with magnetic holder at the back side of level meter graticule, adsorbable on metal material, just can be referring to the be up to the standard situation of position of level meter, its structure is superior, cost is low, can make in a large number, and the value of raising industry utilization.

The use of mean level instrument all is to pin the position that level vial is watched at the level meter two ends again with hand, and this kind method has its shortcoming of using, and outlines as follows:

1. support with hand or pin level meter, has used of a specified duration can acid can be numb, accidentally will fall down, even the damage level instrument.

2. pin the bubble that level meter is watched at two ends again with hand,, tend to have influence on the accuracy of level meter because the stability of hand is big inadequately.

Because modern Science and Technology Day reaches increasingly, and utilize steel frame beam as the framework on the engineering architectural also more and more, so the also more and more chances of the material of construction are used metal material now, especially magnetizable metal, as: iron, metals such as nickel, therefore many new operating techniquies also just in response to and give birth to, and the structure of a kind of improved level meter magnetic holder of the utility model is exactly an example, though yet same principle is used in design commonly used, also be provided with magnetic holder at the back side of level meter exactly, can be adsorbed on the magnetizable metal material, but its shape, structure, still there is considerable problem in places such as device:

1. the shape of Chang Yong design does not just have integrated planning according to the alteration of form of magnet;

The fixing mode of the structure of Chang Yong design be utilize body up and down the elastic clamping hook of both sides be immobilizated in the opening of level meter stand magnetic holder, yet the fragile essential encapsulating everywhere of its system point just lacks structural thus;

3. the device of Chang Yong design is that a box is adorned a magnet and adsorbed two iron plates, and two iron plates prolong two caudas thereafter, can adjust and add a cover the flatness of absorption afterwards, adjust the then whole afterwards encapsulatings in back and fix, and the simple and crude trouble of its method, and impracticable.

Referring to Fig. 1, it is design drawing commonly used, as seen from the figure, one box body 6 can hold magnet and two iron plates 4 and have the lid 7 can enclosed box body 6, box body 6 upper/lower terminals are provided with elastic clamping hook 22, and can hold the level meter stand and open Lu's upper and lower end, but because therefore contact point not too big and insecure; The cauda that the back side of this box body 6 is provided with the cauda 4 that two square holes can two iron plates 4 is regulated and control the flatness of two iron plates 4, and its method is quite simple and crude and efficient is also clear and need encapsulating to bother more; The capping of this lid 7 also be provided with two oblong aperture 9 can allow two iron plates 4 location its to go up its shortcoming the same, the lug 10 of these lid 7 both sides can hold the opening left and right side of stand, can be bonding with box body 6, assist and hold but still need to lean on encapsulating.

The utility model provides a kind of structure of improved level meter magnetic holder, can solve the shortcoming of above-mentioned creation background, the following explanation of its technological means:

Its profile is a flat rectangular parallelepiped and promptly be from the body of the end face of length and width latter half of both sides rip cutting two half-cylindrical gained; It includes a loam cake, a lower cover, two iron plates and a permanent magnet, is provided with a square groove in this loam cake, and this square groove is provided with an oblong aperture towards the outside, and two minor face inboards then are provided with semicircle projection, and is provided with some protruding bolts in the appropriate location; This lower cover also has a square groove, and its structure is also identical with loam cake, and the circular hole that is provided with similar number in the corresponding position of the protruding bolt of this loam cake can be bonded with each other; This two iron plate is inserted in the elongate slots of loam cake and lower cover respectively, and the appropriate neat oblong aperture in the long limit of iron plate one has two concave arcs and can be inserted in that semicircle projection engages mutually in the square groove of upper and lower cover in the middle of two minor faces, make the unlikely oblong aperture that skids off of two iron plates; This permanent magnet can be adsorbed in earlier and cover another lid again on the iron plate of loam cake or lower cover and make permanent magnet adsorb another iron plate again, and the circular hole that utilizes the protruding bolt of loam cake and lower cover is with the upper and lower cover combination; When magnetic holder load level instrument, the tail end of fixator is provided with two square holes can click and enter square hole with glue, can be bonded in the inwall of level meter stand opening, and the upper and lower cover of magnetic holder is provided with laterally runner longitudinally, can be bonding by outside encapsulating, very even flat suitable.

Below shape characteristic of the present utility model, architectural feature, equipment energy characteristic are described as follows:

1. shape of the present utility model is to cooperate allomeric function to design, so its appearance improves according to the rectangle of the stand of level meter, and the rear end of these body both sides has half-cylindrical space not only attractive in appearance but also saving space, processing ease, gains in strength.

2. structure of the present utility model is made up of institutes such as upper and lower covers, and its iron plate can be put into groove location and fixing, is inserted in the magnet adsorpting iron plate again and covers, and this kind mode does not need to adjust the flatness of iron plate, and is quite convenient succinct.

3. the number of times of its encapsulating of device of the present utility model and place all have only secondary, very simplify.And the place of encapsulating is also all very important, and accurately the fixed magnetic fixator is in the open interior space of level meter stand.

Below in conjunction with accompanying drawing the utility model is further specified.
