Description

Technical Field

[0001] The utility model relates to the technical field of 86-type dark box, in particular to a 86-type dark box repair structure. Background Art

[0002] A junction box, as the name suggests, is a box hidden underground, including the concealed connection boxes for points, telephones, and televisions in the room. The existing junction boxes are divided into two types: PVC86 junction boxes and metal 86 junction boxes. During the installation of the junction boxes, due to their own quality and human factors, the fixing nuts on the junction boxes often fall off, resulting in the inability to fix the sealing panel to the base box normally, causing the wiring in the box to be exposed, posing certain safety hazards.

[0003] In order to avoid such phenomena, after the junction box is damaged, the staff often use a junction box repair structure to repair the junction box to ensure that the panel can be smoothly sealed and fixed, and ensure that the circuits in the box will not be exposed. Most of the existing junction box repair structures, such as spring type or top rod type, need to be used in the presence of a bottom box. The spring type junction box repair structure requires an auxiliary tool to install and occupies more space inside the bottom box. The top rod type junction box repair structure has a complicated installation process and poor operability. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4As shown, a 86-type dark box repair structure includes a bottom box body 1, which provides an independent accommodating space for external lines to facilitate the access and collection of wires. A matching inner profile support frame 3 is arranged inside the bottom box body 1, and corner straight plates 31 are arranged at the four corners of the inner profile support frame 3. The corner straight plates 31 and the inner wall of the bottom box body 1 are pressed against each other, and the upper and lower walls of the inner profile support frame 3 are symmetrically provided with protrusions 32, which are located at the central position of the upper and lower ends of the inner profile support frame 3, and at least one group of fixing screw holes 33 are opened on the inner side of the protrusion 32, and a group of fitting grooves 34 are opened on the inner side of the protrusion 32, and the fitting grooves 34 are located at the inner side of the protrusion 32. On the outside of the fixing screw hole 33, a 7-shaped connecting seat 35 is movably connected inside the fitting groove 34. One end of the 7-shaped connecting seat 35 is inserted into the fitting groove 34, and the other end extends to the outer peripheral edge of the bottom box body 1 in parallel with the plane of the bottom box body 1. A matching sealing panel 2 is provided on the front of the bottom box body 1. A fixing screw 4 matching the fitting groove 34 is provided on the front of the sealing panel 2. The sealing panel 2 is fixed to the bottom box body 1 by the fixing screw 4 to form a complete dark box structure. The sealing panel 2 is used to form a good seal on the bottom box body 1. After the wiring is completed, the seal formed by the sealing panel 2 is formed. It can form a good protection for the internal guidance. When the bottom box body 1 is damaged and cannot be effectively fixed with the sealing panel 2, the staff can put the inner contour support frame 3 into the bottom box body 1 and push the inner contour support frame 3 toward the bottom wall of the bottom box body 1, so as to use the corner straight plates 31 arranged at the four corners of the inner contour support frame 3 to squeeze the inner wall of the bottom box body 1, so as to form a stable fixation for the inner contour support frame 3. The symmetrically arranged protrusions 32 on the inner contour support frame 3 are convenient for the staff to open threaded holes, so as to facilitate the connection with the fixing screws 4 through the fixing screw holes 33 opened on the protrusions 32, thereby re-constructing a fixing structure so that the sealing panel 2 can be fixed to the bottom box body 1. The 7-shaped connecting seat 35 is fixed again, and the opening of the fitting groove 34 is used to install the 7-shaped connecting seat 35, which ensures the stability of the 7-shaped connecting seat 35 during work. During the construction process, the owner may temporarily need to add a switch or socket to the wall. However, only corresponding slots can be opened on the gypsum board or wood board wall without reserving a bottom box. At this time, the staff can insert the 7-shaped connecting seat 35 into the fitting groove 34, and then put the inner contour support frame 3 into the slot as a whole, and use the 7-shaped connecting seat 35 and the slot to form a snap-fit ​​structure to fix the inner contour support frame 3, and then complete the fixation between the inner contour support frame 3 and the sealing panel 2, and form a good seal on the slot through the sealing panel 2 to ensure the normal use of the slot.

[0022] The number of the fixing screw holes 33 is three groups, which is convenient for providing multiple fixing points for the fixing screw 4 during later use, thereby ensuring that the fixing screw 4 can be smoothly fixedly connected to the inner contour support frame 3.

[0023] Working principle of the utility model: when the bottom box body 1 is damaged and cannot be fixed with the sealing panel 2, the staff can put the inner profile support frame 3 into the bottom box body 1, and connect the fixing screw 4 with the fixing screw hole 33 provided on the protruding part 32 to fix the sealing panel 2 on the bottom box body 1;

[0024] During the construction process, when it is temporarily necessary to add a switch or socket to the wall, but only the corresponding slot can be opened on the gypsum board or wood board wall without a reserved bottom box, the staff can insert the 7-shaped connecting seat 35 into the matching groove 34, and then put the inner profile support frame 3 into the slot as a whole, and use the locking structure formed between the 7-shaped connecting seat 35 and the slot to fix the inner profile support frame 3, and then completely fix the sealing panel 2 on the inner profile support frame 3 to form a good seal for the slot.

[0025] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
