Description

A fixture for hollow brick walls

technical field

The utility model relates to the field of installation of electric meter boxes, in particular to a fixing piece for hollow brick walls.

Background technique

At present, hollow bricks are often used for building walls instead of solid bricks as the building materials for the walls. Even if the meter box is installed in another location on the wall, the overall installation will be limited due to problems such as the sink under the roof. Existing expansion screws are used in The wall made of hollow bricks is difficult to fix. The inventor found that if the expansion screws are forced to be used, there will be a phenomenon of rotating and slipping, making them unable to be fastened, which not only takes time and labor, but also reduces the use efficiency of the expansion screws. It leaves a damaged mark on the surface of the wall and affects the beauty of the wall.

Detailed ways

It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

It should be noted that the terminology used herein is for describing specific embodiments only, and is not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly dictates otherwise, the singular is intended to include the plural as well, furthermore, it is to be understood that when the terms "comprising" and/or "including" are used in this specification, it indicates that There are features, steps, operations, devices, components and/or combinations thereof.

As described in the background art, there are deficiencies in the prior art. In order to solve the above technical problems, the utility model proposes a fixing piece for a hollow brick wall. The utility model is further described below with reference to the accompanying drawings. elaborate.

In a typical embodiment of the present invention, as shown in Figures 1 and 2, a fixing piece for a hollow brick wall includes a bolt 1, and the bolt 1 is covered with a deformable thread buckle 4. The deformable thread buckle 4 includes a screw thread head 4a and a screw tail 4c, the screw head 4a and the screw tail 4c are connected by a screw body 4b, the inner side of the screw tail 4c is provided with a thread, and the screw tail 4c is fixed with the bolt 1 The size of the head of the threaded buckle is larger than the size of the bolt, and the body 4b of the threaded buckle includes several retractable strips 4d. There is a set distance between the telescopic strips 4d, the bolt 1 is sleeved with a clamping nut 2 between the bolt head and the head of the thread buckle, the clamping nut 2 can cooperate with the bolt 1, and the clamping nut 2 and the head of the thread buckle A spacer 3 is provided between 4a.

Among them, the retractable bar 4d is made of spring steel, which has a certain elastic deformation capacity, such as 65Mn, and the retractable bar 4d is arranged in a wave shape along the length direction of the bolt, so that when the clamping nut is rotated, the thread buckle head 4a It is compressed, and correspondingly drives the threaded buckle body 4b to deform until the threaded buckle body and the wall are completely fixed. At this time, the shape of the fixing member is shown in Figure 3 or Figure 5. The front side is in contact with the hole in the wall to increase friction, and the deformed part of the threaded fastener body (the circumferential dimension is larger than the front side of the threaded fastener body) is in contact with the wall to block the movement of the bolt.

Among them, the bolt 1 has a nut, the clamping nut 2 can be a hexagonal nut, which can effectively cooperate with the bolt 1, and the gasket 3 is a rigid gasket. When the gasket is in use, it is installed on the clamping nut 2 and the hollow brick wall 5. between the outside.

It should be noted that the length of the bolt screw is greater than the thickness of one side of the hollow brick wall (the distance between the front side of the hollow brick hollow section and the outer side surface of the wall), and the size of the threaded buckle body and the threaded buckle head is larger than that of the hollow brick wall body 5. The thickness of one side is convenient for the deformation of the thread buckle body after passing through the wall body after being compressed, and the part arranged in the hole of the wall body will not be greatly deformed.

A fixing piece for a hollow brick wall, the specific use steps are as follows:

Use a punching machine larger than the screw size of bolt 1 (greater than or equal to the size of the tail of the screw thread) to drill the wall;

Set the objects to be fixed (which can be meter boxes or other objects) on one side of the wall;

Rotate the clamping nut 2 and the washer 3 to the screw rod of the fixing bolt, and set the clamping nut 2 close to the head of the bolt 1;

Install the thread buckle 4 to the bolt 1, the thread buckle head 4a is in contact with the gasket 3, and the thread buckle body 4b is in an extended state; the inner side of the thread buckle tail 4c is provided with threads, and the thread mouth tail 4c is aligned with the bottom thread of the bolt screw;

Insert the installed fixing bolts through the fixing holes of the meter box and insert them into the openings of the wall, and rotate the clamping nut 2, so that the thread buckle body 4b expands outward in the hollow section of the hollow brick wall 5 and deforms until the thread The buckle body 4b is completely fixed with the wall. At this time, the shape of the fixing member is shown in Figure 3. The deformed size of the threaded buckle body 4b is larger than the size of the opening of the wall 5, and the size of the gasket 3 is also larger than the opening of the wall 5. The size of the hole; the front side of the threaded fastener 4b is in contact with the hole to increase friction, and the deformed part of the threaded fastener is in contact with the wall, as shown in Figure 4, to block the movement of the bolt 1;

As shown in Figures 5 and 6, when the thickness of one side of the hollow brick wall 5 is changed, when the clamping nut 2 is rotated, the threaded fastener portion 4b will deform in different sizes, and the wall clamp of different thicknesses can be realized by bending itself. tight;

When the hole diameter of the wall is different, by rotating the clamping nut 2, the threaded body can also bend itself to make it contact with the hole, while increasing the friction, the bolt is effectively fixed, so that the object to be fixed is connected to the wall. body fixed.
