Description

Cassette

Technical Field

The invention belongs to the field of electricians, and relates to a cassette for connecting a wall switch socket.

Background

In the cassette sold in the market, most of nuts connected with the wall switch socket are fixed on the inner side frame wall of the cassette frame body, and the nuts are movable and can be conveniently aligned to screw holes and screws which are symmetrical through two sides of the wall switch socket when the nut is installed. Both types of cassettes have a common drawback in use and installation, i.e. the cassette can only be replaced if the nut is damaged. When the nut is screwed or loosened from the frame wall at the inner side of the frame body, the connected and fixed wall switch socket can be loosened and fall off. The replacement of the magazine is difficult and troublesome to destroy the wall. Although the market has a bottom box repairing brace rod, the market is also a sheep death mending. The stability and the firmness are inferior to those of original cassettes. For the wall surface pasted with the ceramic tiles, because the hidden box is installed firstly and then the ceramic tiles are pasted, sometimes the hidden box can sink into the wall deeply, the screw needs to be lengthened when the wall switch socket is connected, the length of the screw needs to be selected, the wall switch socket needs to be temporarily sold, and the wall surface is troublesome. The installer can also artificially damage the nut of the cassette when installing the wall switch socket, and the installer can use the method for remedying the problem that the hidden danger of loosening is buried when the installer uses and replaces the wall switch socket later by inserting the wire sheath into the nut and screwing the nut with a wood screw.

Disclosure of Invention

The invention aims to solve the problems existing in the use of the cassette, and provides the cassette which can be replaced, adjusted in length and moved, simple in structure, convenient to install and durable when a nut is damaged or slides.

The technical solution of the invention is as follows: two schemes with the same principle and consistent functions:

scheme one, the frame wall of framework inboard is not only can link to each other but also separable subassembly with the nut of fixing at removal strip both ends and mutually as an organic whole with the removal strip, can connect and fix wall switch socket when linking to each other, removable nut during the separation. The frame wall is provided with two opposite groove walls and a groove between the two opposite groove walls, the groove is provided with a spare hole 10, two ends of the groove walls are provided with catching grooves 6, and one side of the groove walls is provided with a catching groove 7. The moving bar is provided with a nut, a spare hole 11 and loop bars at two sides, the loop bars are wider than the groove walls at two sides of the groove, the moving bar is narrower than the groove, the distance between the loop bars is slightly shorter than or equal to the distance between the outer ends of the catching grooves 6 at two ends of the groove walls, and the catching grooves 6 and the catching grooves 7 can be sleeved in the loop bars and the moving bar.

And in the second scheme, the two groove walls are combined to form a wide groove wall, the two ends of the wide groove wall are provided with the catching grooves 6, one side of the wide groove wall is provided with the catching grooves 7, the moving bar I is cut into two parts, the loop bars on the two sides are in butt joint connection to obtain the moving frame, the hollow periphery of the moving frame is a moving frame bar, the two sides of the moving frame bar are wider than the wide groove wall, the distance between the moving frame bars in the nut direction is slightly shorter or equal to the distance between the outer ends of the catching grooves 6 on the two ends of the wide groove wall, the catching grooves 6 and the catching grooves 7 can be sleeved into the moving frame bar.

Because the cassette is connected and fixed with the wall switch socket by the screws which pass through the symmetrical screw holes at the two sides of the wall switch socket and are screwed on the internal nuts of the cassette, the frame wall nut components at the two sides in the frame body have the same structure and belong to the same technical scheme. The invention is made of the existing commercial cassette material.

Detailed description of the preferred embodiments

According to the first scheme: referring to fig. 1, when the cassette frame 1 is embedded in a wall, referring to fig. 2-1, a finger grips a loop bar 9 at one end of a moving strip 4 with a nut 3, and the loop bar is sleeved in a buckle groove 6 at one end of a groove wall 5, which is opposite to the frame wall 2, and referring to fig. 4-1, the position a of the loop bar 9 is sleeved in the position d of the buckle groove 6. In the figures 2-1, 2-3 and 2-4, because the distance between the loop bar 9 and the loop bar 9 is slightly shorter or equal to the distance between the outer ends of the catching grooves 6 at the two ends of the groove wall 5, but at this time, one end of the loop bar 9 enters the inner edge of the catching groove 6, and is influenced by the distance, the distance between the loop bar 9 at the other end is slightly longer than the distance between the outer ends of the catching grooves 6 at the other end of the groove wall 5, as shown in figures 4-1 and 4-3, because the position a of the loop bar 9 is sleeved in the inner edge g of the catching groove 6, the position b of the loop bar 9 is longer than the outer end. The moving strip 4 is lightly pushed into the catching groove 6, fingers are loosened, the moving strip 4 falls into the catching groove 7 due to the self weight shown in figure 2-2, and the moving strip 4 cannot be separated from the catching groove 6 and the catching groove 7 under the action of non-manpower. To install the wall switch socket, only need to pass the screw through the screw of wall switch socket panel both sides screw and face the nut 3 of frame wall 2 both sides, meet that the screw has some distance error with nut 3, because remove strip 4 and be narrower than groove 8, remove strip 4 and can remove in groove 8, only need embolia nut 3 with the screw and pull gently, can adjust the butt joint position. The screw is screwed into the nut 3, and along with the tightening of the screw, fig. 2-1 and 2-2, because the loop bar 9 is wider than the groove walls 5 at the two sides of the groove 8, fig. 4-1 and 4-3, and because the loop bar 9 is sleeved into the position e of the buckle groove 6 at the position b, the loop bar 9 is sleeved into the inner edge g of the buckle groove 6 under the action of the pulling force of the screw, and the loop bar 9 can not be separated from the buckle groove 6 under the non-manual action. In fig. 2-4, the moving strips 4, the nuts 3 and the rods 9 are integrated with each other, and the tightened screws finally tightly connect the wall switch socket with the nuts 3. If the nut 3 is damaged or slips, the nut 3 at the other end of the movable strip 4 can be used in the figures 2-2 and 2-4, the movable strip 4 is only required to be rotated in one direction, the position c of the loop bar 9 and the position a of the loop bar 9 are exchanged in the figure 4-1, the position b of the loop bar 9 is not changed, the installation steps are repeated, and a new movable strip 4 can be directly exchanged. Supposing that the service life of the cassette is too long and unexpected faults occur, the nut 3 is good, but the loop bar 9 or the buckle groove 6 has problems, at this time, only a short nail with the same inner diameter as the spare hole 11 is needed to be found and inserted into the spare hole 10 in the slot 8 from the spare hole 11 on the movable strip 4, and the cassette can still be connected and fixed with the wall switch socket. If the wall surface is stuck with thick tiles, the screw cannot reach the nut 3, as shown in fig. 4-1, the sleeve rod 9 at the position b is sleeved into the buckling groove 6 at the position d, and the sleeve rod 9 at the position c is sleeved into the buckling groove 6 at the position e, so that the nut 3 approaches the wall surface tiles to connect the upper screw, the wall switch socket is fixed, and the effect of adjusting the length of the nut 3 is achieved.

As the distance between the movable frame strips 14 in the direction of the nut 3 is slightly shorter or equal to the distance between the outer ends of the catching grooves 6 at the two ends of the wide groove wall 12, as shown in FIGS. 3-1 and 3-2, but at this time, one end of the movable frame strip 14 enters the catching groove 6, and the distance between the movable frame strip 14 at the other end is slightly longer than the distance between the outer ends of the catching grooves 6 at the other end of the wide groove wall 12, as shown in FIGS. 4-2 and 4-3, because the position a of the movable frame strip 14 is sleeved in the inner edge g of the catching groove 6, the position b of the movable frame strip 14 is. The movable frame strip 14 is lightly pushed into the buckling groove 6, fingers are loosened, and due to the weight of the movable frame strip 14, as shown in fig. 3-2, the movable frame strip 14 falls into the buckling groove 7, and the movable frame strip 14 cannot be separated from the buckling groove 6 and the buckling groove 7 under the non-manual action. When the wall switch socket is to be installed, the screws only need to pass through the screw holes on the two sides of the panel of the wall switch socket and face the nuts 3 on the two sides of the frame wall 2, when the screw holes and the nuts 3 have some distance errors, the two sides of the movable frame strip 14 are wider than the wide groove wall 12, the movable frame strip 14 can move in the buckle groove 6 and the buckle groove 7, and the butt joint position can be adjusted only by slightly pulling the screws into the nuts 3. The screw is screwed into the nut 3, and with the tightening of the screw, fig. 3-1, 3-2, because the movable frame strip 14 is wider than the wide slot wall 12, fig. 4-2, 4-3, and because the position b of the movable frame strip 14 is sleeved into the position e of the buckle slot 6, the movable frame strip 14 is sleeved into the inner edge g of the buckle slot 6, and the movable frame strip 14 can not be separated from the buckle slot 6. In fig. 3-3, the movable frame 13, the movable frame 14 and the nut 3 are integrated with each other, and the tightened screw finally tightly connects the wall switch socket with the nut 3. If the nut 3 is damaged or slips, the nut 3 at the other end of the movable frame 14 can be used as shown in fig. 3-1 and 3-3, and the movable frame 14 is only required to be rotated in one direction, namely, the position c of the movable frame 14 is exchanged with the position a of the movable frame 14, the position b of the movable frame 14 is not changed, the installation steps are repeated, and a new movable frame 13 can be directly exchanged. If the wall surface is stuck with thick tiles, the screw cannot reach the nut 3, as shown in fig. 4-2, the nut 3 is connected with the screw close to the wall surface tiles by only sleeving the position b of the movable frame strip 14 into the position d of the buckle slot 6 and sleeving the position c of the movable frame strip into the position e of the buckle slot 6, so that the wall surface switch socket is fixed, and the effect of adjusting the length of the nut 3 is achieved.
