[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it shall be protected by the patent law.

[0026] Examples, such as Figure 1-6As shown, a wire controller structure includes a rear cover 1 for fixed installation, a middle cover 2 that can be detachably installed in the rear cover 1, and a front shell 3 plugged and installed on the front side of the middle cover 2. The rear cover is used to be installed and fixed to a building installation surface such as a wall. The rear cover can be fixed to the building installation surface by pasting or screw locking, and the front shell 3 and the middle cover 2 can be pre-assembled and connected to form a wire controller body, and then the body is detachably installed and connected with the rear cover through the middle cover. When assembling the wire controller body, the LCD screen, circuit board, etc. can be put inside and assembled together. In this way, the wire controller body can play the function of the wire controller itself, and the rear cover 1 is an indirect installation structure, which makes the installation applicability of the wire controller better. Among them, the rear cover 1 forms a temporary storage installation groove 10 with an opening facing forward. The temporary storage installation groove 10 is generally rectangular, and the notch is arranged forward. Furthermore, more than 70% of the middle cover 2 is in the temporary storage installation groove 10, which can not only reduce the volume and space occupancy, but also make the assembly tighter and the installation stronger. Further, the middle cover 2 forms an intermediate component placement groove 20 with an opening facing forward. The rear cover 1 and the middle cover 2 are generally selected to be a square cover structure with an overall rectangular shape. The front shell 3 is also a square cover structure. The intermediate component placement groove 20 is used to install circuit boards, diaphragms and other components. Some components are in the front shell 3, such as liquid crystal screens and positioning diaphragms. In particular, a forward-extending reinforcing plug-in column 20 is fixed in the intermediate component placement groove 20. The reinforcing plug-in column 200 is used for the assembly of the middle cover 2 and the front shell 3, and the front shell 3 is plugged and installed on the reinforcing plug-in column 200 backward. The entire installation process is to assemble the middle cover 2 and the front shell 3 and the intermediate components sandwiched between the two to form the wire controller body. The wire controller body can be detachably installed and disassembled with the back cover through the middle cover 2, and the back cover 1 can be fixed to the building installation surface in advance, and the back cover 1 can be installed and fixed to the building installation surface by various fixing methods. The back cover 1 is actually an intermediate transition installation structure between the building installation surface and the wire controller body. Then, the size and shape of the outer periphery of the back cover 1 can actually have more choices, as long as the temporary storage installation groove 10 on the inner side can be entered by the middle cover 2 and detachably connected, and this detachable structure needs to be relatively not easy to be damaged, so as to ensure the long-term use of the wire controller body, and the back cover 1 can not only be installed in a variety of ways during the installation process, but also multiple alignments, multiple nailings or damage during later use during the installation process will not affect the wire controller body, the cost of using the wire controller product can be reduced, and it is also conducive to recycling and reuse.If you install the middle cover directly like the existing method, for the safety and stability of the installation, you need to use standard fixings to install it, and try to avoid problems with the middle cover installation. However, this will limit the applicability of the installation. For example, some occasions are not suitable for fixings because some installation surfaces are special-shaped or irregular. In this case, it is likely that the installation cannot be performed. The present application solves the problem of installation restrictions on the one hand, and has better applicability, and on the other hand, it can make the wire controller body not need to be directly installed and fixed to the building installation surface. In this way, it is also a kind of protection for the wire controller body, and it is also more convenient for maintenance, replacement, reuse, etc.

[0027] Preferably, the rear cover 1 includes a rear groove bottom mounting plate 11 and a rear upper baffle 12, a rear left baffle 13, a rear lower baffle 14 and a rear right baffle 15 which are integrally connected to the front surface of the rear groove bottom mounting plate 11 and extend forward, the rear groove bottom mounting plate 11, the rear upper baffle 12, the rear left baffle 13, the rear lower baffle 14 and the rear right baffle 15 surround and form the temporary storage mounting groove 10, which is an example of a square cover body, the rear groove bottom mounting plate 11 is a square upright plate, and the front side is integrally connected with the rear upper baffle 12, the rear left baffle 13, the rear lower baffle 14 and the rear right baffle 15 which are connected in sequence from head to tail to form a square frame, these five plates surround and form a square temporary storage mounting groove 10, and the outer shape structure of the middle cover can be similar to the rear cover 1 here, because it is used as the outer shell structure at the rear of the wire controller body, and it itself needs to be a regular square shape. The middle cover 2 includes a middle groove bottom plate 21 and a middle upper baffle 22, a middle left baffle 23, a middle lower baffle 24 and a middle right baffle 25 which are integrally connected to the front side surface of the middle groove bottom plate 21 and extend forward. The middle groove bottom plate 21 is an upright square plate, and the middle groove bottom plate 21, the middle upper baffle 22, the middle left baffle 23, the middle lower baffle 24 and the middle right baffle 25 surround and form the middle component placement groove 20. In this way, the middle cover 2 can be nested backward in the temporary storage installation groove 10 of the rear cover 1, so the size of the rear cover 1 is larger than that of the middle cover 2, especially the size of the temporary storage installation groove 10 is basically matched with the outer size of the middle cover 2, that is, the size deviation should be as small as possible to facilitate nesting, and of course, it cannot be completely consistent, because it is preferred to have a corresponding nesting structure to better position and connect. A further design is made based on this, that is, the middle cover 2 is embedded and installed backward into the temporary storage installation groove 10, and the middle cover 2 and the rear cover 1 are embedded and locked by an embedded snap-fit ​​connection structure, that is, after being embedded, they are further locked and connected by snap-fit. The specific snap-fit ​​structure is as follows: the embedded snap-fit ​​connection structure includes an upper concave snap-fitting portion 221 formed on the upper surface of the middle upper baffle 22 and a downwardly protruding upper snap-fitting portion 121 formed on the lower surface of the rear upper baffle 12 and cooperating with the upper concave snap-fitting portion 221. The upper concave snap-fitting portion 221 is a groove Structure, and the upper raised snap-fitting portion 121 is a raised structure, which is just snapped into the groove structure to form a snap-fitting structure, so that the stability of the installation connection is better. This is the snap-fitting at the upper side, so a corresponding snap-fitting structure is also needed on the lower side accordingly, so that the snap-fitting stability is higher. Similarly, the embedded snap-fitting connection structure also includes a lower recessed snap-fitting portion 241 formed on the lower surface of the middle and lower baffle plate 24 and a lower raised snap-fitting portion 141 formed on the upper surface of the rear lower baffle plate 14 and protruding upward and cooperating with the lower recessed snap-fitting portion 241.Of course, in order to meet the needs of this snap-fit ​​structure, further optimization is done, that is, the back cover 1 and the middle cover 2 are both plastic bodies, that is, they need to have a certain deformation ability, so that it is convenient for disassembly and assembly and snap-fit ​​connection. The meaning of plastic body is that the back cover 1 and the middle cover 2 can be produced by existing plastic materials. Conventional wire controllers generally also use plastic products, and the front shell 3 is also preferably a plastic product, which is processed and manufactured by one-piece molding.

[0028] Preferably, the upper protruding engaging portion 121 and the lower protruding engaging portion 141 are both semi-cylindrical protrusions extending left and right. The arcuate arched portion of the upper protruding engaging portion 121 is at the bottom, and the arcuate arched portion of the lower protruding engaging portion 141 is at the top. In order to better cooperate with this protruding engaging portion, the upper concave engaging portion 221 can adopt a strip-shaped rectangular groove extending left and right, and similarly, the lower concave engaging portion 241 can also adopt a strip-shaped rectangular groove extending left and right and can be used for the protruding engaging portion to be clamped into the limit position. In order to better clamp and install and remove, an upper guide installation slope a1 tilted forward and downward can be formed on the rear side of the groove of the upper concave engaging portion 221, and a lower guide installation slope a2 tilted forward and upward can be formed on the rear side of the groove of the lower concave engaging portion 241, so that it is easy to be inserted into position when clamping the front and rear, and it is relatively easy to pull the guide deformation before and after removal, and it can still ensure sufficient limit locking effect after installation. In terms of quantity, two upper protruding engaging parts 121 can be provided, one for each mirror image on the left and right, and two upper recessed engaging parts 221 are provided accordingly. However, the lower protruding engaging parts 141 are different, because a wire inlet hole b that passes from top to bottom is formed at the right position of the lower side of the middle cover and the rear cover. Therefore, in order to improve the strength and the clamping installation, a lower protruding engaging part 141 can be provided on the right side of the wire inlet hole b, and two lower protruding engaging parts 141 can be provided on the left side of the wire inlet hole b, and the corresponding lower recessed engaging parts 241 are three. Such a structure is more stable.

[0029] Furthermore, a plug-in rod 301 is formed on the front shell 3, which extends backward and can be inserted backward into the reinforced plug-in column 200, and the cylindrical structure of the reinforced plug-in column 200 extends forward and backward. The reinforced plug-in column 200 is 4 and is integrally formed and connected to the front surface of the middle groove bottom plate 21. The reinforced plug-in column 200 is at the four corners of the middle groove bottom plate 21. The front shell 3 also adopts a square cover structure and forms a front accommodating groove, but the notch of the front accommodating groove faces backward and is connected to the middle component placement groove 20 for cooperation. The front shell 3 correspondingly includes a front panel 31 and a front upper baffle 32, a front left baffle 33, a front lower baffle 34 and a front right baffle 35 integrally connected to the rear surface of the front panel 31. The plug-in rods 301 are also four and are integrally connected to the four corners of the rear surface of the front panel 31. The plug-in rods 301 and the reinforced plug-in column 200 correspond to each other front and back.

[0030] The specific plug-in structure is as follows: the axial part of the reinforced plug-in column 200 forms a plug-in hole 201, a screw rod through hole 202 and a screw head operation hole 203 that are connected front and back, the plug-in hole 201 is for the plug-in rod 301 to be inserted, the hole diameter of the plug-in hole 201 is larger than the screw rod through hole 202, and the rear part of the plug-in rod 301 is provided with a screw rod locking hole 3011 that is connected to the plug-in hole 201. The diameters of the plug-in holes 201 and the plug-in holes 201 are kept consistent as much as possible, so that the plug-in is tighter. Of course, this kind of plug-in is well limited in the vertical direction, but it is still easy to loosen in the front and rear directions, so if further connection is needed, screws or bolts need to be involved. The screws or bolts have screw heads and screw rods. Among them, the screw head operation hole 203 not only passes through the reinforced plug-in column 200, but also penetrates the middle groove bottom plate 21 backward, and the hole size of the screw head operation hole 203 is also larger than the screw rod through hole 202. In this way, when the front shell and the middle cover are installed in the front and rear through the plug rod 30 After the front shell and the plug-in hole 201 are assembled and plugged, they can be further fixed by bolts, that is, the screw of the bolt passes through the screw head operation hole 203, the screw through the hole 202 and the plug-in hole 201 and can reach the screw locking hole 3011 of the plug-in rod 301, and then the screw is screwed deeper into the screw locking hole 3011 by the screw head, and the plug-in rod 301 is better fixed against the plug-in hole 201, and the four corners are locked by a bolt, so that the installation and fixation of the front shell and the middle cover can be better completed. During the installation of the shell and the middle cover, it is necessary to place the circuit board, diaphragm, etc. between the two. Here, these components can be punched with positioning holes at the four corners, and the plug-in rod 301 can pass through these positioning holes and then be inserted into the plug-in hole 201, so that these components can be assembled and positioned together. In addition, for the sake of structural strength and installation guidance, a step portion b1 is formed on the rear groove of the front upper baffle 32, the front left baffle 33, the front lower baffle 34 and the front right baffle 35, and the step is inward, while the front side plate surfaces of the middle upper baffle 22, the middle left baffle 23, the middle lower baffle 24 and the middle right baffle 25 are integrally connected to form a front reinforcing raised edge b2 that abuts against the step portion b1.

[0031] Preferably, a hanging installation hole 2100 is formed on the bottom plate 21 of the middle groove for hanging and passing through the middle groove from front to back. The hanging installation hole 2100 includes an upper bar-shaped hanging hole 2101 and a lower entry adjustment hole 2102 which are connected from top to bottom. The left and right dimensions of the upper bar-shaped hanging hole 2101 are smaller than the left and right dimensions of the lower entry adjustment hole 2102. The hanging installation hole 2100 can be provided with a gourd-shaped pattern on the left and right sides, so that the head of the hanging nail can be put into the entry adjustment hole 2102 from the bottom, and then the middle cover sinks, so that the rod of the hanging nail enters the upper bar-shaped hanging hole 2101 for hanging. Of course, hanging parts other than hanging nails can also be used for hanging. In this design, the hanging installation on the installation surface can be directly performed without the back cover as needed. If the protection of the back cover is required, two waist-shaped adjustment holes c1 that run through the front and back need to be opened on the back cover, one horizontal and one vertical, for the suspension part to adjust the position, with enough margin for adjustment, and then the suspension part is hung on the suspension mounting hole 2100. In this case, the back cover does not need to be fixed to the mounting surface in advance. For the compactness of the suspension, the front limit baffle c2 located in front of the suspension mounting hole 2100 is integrally connected on the middle groove bottom plate 21 and has a shape similar to the suspension mounting hole 2100 and is opposite to the front and back, so that the head of the suspension part can be stuck between the front limit baffle c2 and the upper strip suspension hole 2101 of the suspension mounting hole 2100. This installation method is suitable for temporary use. The usual installation method is to fix the back cover on the mounting surface, and then snap the main body of the wire controller on the back cover.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
