[0029] See also Figure 1-9 As shown, as an embodiment of the utility model, a pre-embedded box for wall installation is provided, comprising a cylindrical box body 1 and a fixing ring 2 which is position-adjustably mounted on the circumferential outer wall 12 of the box body 1, a plurality of fixing holes 3 are opened on the fixing ring 2, bolts pass through the fixing holes 3 and are locked with the wall, a plurality of mounting groove groups are arranged along the axial direction on the circumferential outer wall 12 of the box body 1, each mounting groove group comprises a plurality of mounting grooves 4 arranged along the circumferential direction of the box body 1, and the mounting grooves 4 are concave to form a limiting portion 5, at least two kinds of buckles are arranged on the circumferential inner wall of the fixing ring 2, the buckles comprise an elastic buckle 6 and a fixed buckle 7, the fixed buckle 7 is rotatably clamped at the end of the mounting groove 4, the elastic buckle 6 is clamped and limited with the limiting portion 5, and the technical solution only requires the fixing ring 2 to be rotated in the mounting groove 4 so that the fixing buckle 7 is rotated and clamped at the end of the installation groove 4, and the elastic buckle 6 is locked and limited with the limiting part 5, so that the fixing ring 2 can be fixedly installed on the circumferential outer wall 12 of the box body 1, without the introduction of external components such as wedges, and the installation and fixing structure between the fixing ring 2 and the box body 1 is also relatively simple, and the operation is more convenient and quick. Through the cooperation of two different types of buckles, the fixing buckle 7 and the elastic buckle 6, the fixing ring 2 can be rotationally limited on both sides of the rotation direction, which is not easy to loosen and has better installation stability; in addition, since the fixing ring 2 is installed on the circumferential outer wall 12 of the box body 1 in an adjustable position along the axial direction, the embedded box can be set before installation. The installation depth or the distance protruding from the wall, that is, the embedded box is installed in the embedded hole with adjustable depth, which can adapt to different installation depths, and the installation accuracy and efficiency are higher.

[0030] In this embodiment, the limiting portion 5 is a recessed notch provided at the installation groove 4, and the elastic buckle 6 is engaged with the notch for locking and limiting. Of course, in other cases, the limiting portion 5 can also be a convex buckle provided at the installation groove 4, and the elastic buckle 6 can also be engaged with the convex buckle for locking and limiting.

[0031] In this embodiment, the front and rear ends of the box body 1 are respectively a box opening 11 and a base 13, and the installation groove 4 includes an entrance groove 41 extending in the axial direction to the box opening 11 and an arcuate groove 42 located on the side of the entrance groove 41 away from the box opening 11 and extending in the circumferential direction, the arcuate groove 42 gradually narrows toward the end away from the entrance groove 41, and the recess is located in the arcuate groove 42, and the elastic buckle 6 or the fixed buckle 7 on the fixing ring 2 is respectively inserted into the entrance groove 41 along the box opening 11, and then rotated along the arcuate groove 42, so as to realize the rotation and clamping of the fixed buckle 7 at the end of the installation groove 4, and the elastic buckle 6 falls into the recess for clamping and limiting cooperation, and the installation operation is simpler, faster, smoother and more accurate.

[0032] In the present embodiment, each mounting groove group includes four mounting grooves 4 evenly arranged along the circumferential direction of the box body 1, and there are four clips, which are evenly arranged on the circumferential inner wall of the fixing ring 2, that is, the angles between two adjacent clips are 90°. Among them, since the processing difficulty of the elastic clip 6 is greater than the processing difficulty of the fixed clip 7, the four clips are respectively one elastic clip 6 and three fixed clips 7. The number of elastic clips 6 is relatively small, so that the overall processing difficulty of the fixing ring 2 is relatively small, and the most basic stability can also be guaranteed. In addition, it is also easier and more convenient to disassemble the fixing ring 2. It is only necessary to apply force to one elastic clip 6 to make it elastically deform and detach from the recess; and the purpose of the uniform setting is to make the elastic clip 6 and the fixed clip 7 correspond to the mounting groove 4 one by one, and are not fixed to a specific position, so that blind installation can be realized, further improving the installation efficiency.

[0033] In this embodiment, a clearance gap 8 with one end open is formed on the periphery of the fixing ring 2 corresponding to the elastic buckle 6, so that the elastic buckle 6 can elastically move along the radial direction of the fixing ring 2, thereby achieving the locking and limiting or releasing of the elastic buckle 6 at the recess.

[0034] In this embodiment, the clearance gap 8 is C-shaped, and its opening is located at the end of the screw-in direction corresponding to the elastic buckle 6. A limit block 9 is provided on the inner wall of the fixing ring 2 on the side where the opening of the clearance gap 8 is away from the elastic buckle 6. The limit block 9 cooperates with the end groove wall of the arc-shaped groove 42 to block and limit the fixing ring 2, so that after the fixing ring 2 is rotated clockwise and locked in place, it can prevent the fixing ring 2 from continuing to rotate clockwise, that is, the function of the limit block 9 is the same as that of the fixing buckle 7, further improving the installation stability of the fixing ring 2.

[0035] In this embodiment, the screw-in direction is clockwise, and the screw-out direction is counterclockwise. The elastic buckle 6 includes a main body 61, a buckle part 62 arranged on the inner side of the main body 61, and a lever part 63 vertically arranged below the main body 61 on a side away from the buckle part 62. The buckle part 62 is engaged with the notch to limit the position. By pulling the lever part 63 outward, the elastic buckle 6 as a whole can be elastically deformed outward along the radial direction of the fixing ring 2, so that the buckle part 62 is disengaged from the notch and released from the locking and limiting position. Then, the fixing ring 2 is rotated counterclockwise to easily disassemble and remove the fixing ring 2. Among them, the lever part 63 can be set at any position of the main body 61, such as above the main body 61, and there is no restriction here.

[0036] In this embodiment, the limiting portion 5 is a rectangular recess, and the end of the buckle portion 62 corresponding to the screw-out direction is a right-angle structure 621. The side wall of the rectangular recess cooperates with the right-angle structure 621 to block the limiting position. The above-mentioned structural setting enables the fixing ring 2 to be prevented from rotating out in the counterclockwise direction after being rotated clockwise and locked in place.

[0037] In this embodiment, a guiding slope 622 is provided on the bottom side of the buckle portion 62, and the guiding slope 622 is used to elastically squeeze and cooperate with the box opening 11 to guide the buckle portion 62 into the installation groove 4, making the installation process of the fixing ring 2 easier and more labor-saving.

[0038] In this embodiment, the top surface of the main body 61 is provided with an arrow mark 10 pointing toward the lever portion 63 , which is used to prompt the user to pull the lever portion 63 outward to achieve the disassembly operation of the fixing ring 2 .

[0039] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes made to the present invention in form and detail, without departing from the spirit and scope of the present invention as defined in the appended claims, shall fall within the scope of protection of the present invention.
