Description

Technical Field

[0001] The utility model relates to the field of distribution boxes, in particular to a distribution box capable of adjusting the inner and outer positions of an installation beam. Background Art

[0002] The distribution box is a complete set of components used to control electrical equipment and protect against overload, short circuit and leakage. It generally includes a box body, a mounting beam for installing a leakage switch, and a terminal block for connecting to external wires and leakage switches. Due to the different sizes of leakage switches, in order to facilitate the installation of leakage switches and ensure that the leakage switch can be located just in the operating hole of the cover after the leakage switch is installed, so as to facilitate user operation, the installation beam generally requires that the internal and external positions can be adjusted in the distribution box, such as a modular terminal distribution box disclosed in patent No. 203632030U. However, there is a problem that the fixing bolt is located on the side of the guide rail. When the leakage switch is installed, the fixing bolt is just opposite to the side of the leakage switch, and the gap between the leakage switch and the inner wall of the distribution box is generally small, which causes the installer to adjust the front and rear position of the installation beam before installing the leakage switch. First, the position of the installation beam cannot be accurately controlled, and second, the installation process of the leakage switch is not smooth, which is more troublesome for the installer to install. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a distribution box which is convenient for adjusting the position of the installation beam and also convenient for installing the leakage switch.

[0004] The technical solution adopted by the utility model to solve the problem is: a distribution box, comprising a distribution box body, wherein an installation cavity is arranged in the distribution box body, and a surface cover for covering the installation cavity is arranged on the distribution box body;

[0005] Adjustment bases are installed on both the left and right sides of the installation cavity, and two sets of limit plates are arranged on the surfaces of the two adjustment bases facing each other in the up-down direction, and the two sets of limit plates enclose and form adjustment slots arranged in the inward-outward direction;

[0008] The installation beam has two ends which are respectively fixed on the two adjustment blocks.

[0009] As a further improvement of the above technical solution, both sides of the limit plate and / or the adjustment block are elastic so that the inner wall of the limit plate abuts against the surface of the adjustment block and presses against each other.

[0011] As a further improvement of the above technical solution, the engaging position is a positioning convex rib.

[0012] As a further improvement of the above technical solution, the adjustment block includes a main body and elastic side plates arranged on the upper and lower sides of the main body and popping outward, and the upper and lower sides of the main body are provided with avoidance spaces for the elastic side plates to deform inward, and the locking position is arranged on the top outer surface of the elastic side plate.

[0013] As a further improvement of the above technical solution, deformation stop plates are also provided on the upper and lower sides of the adjustment block, the edge of the deformation stop plate is located at the front end of the engagement position, and the maximum distance between the edges of the deformation stop plates on both sides of the adjustment block is less than the minimum width of the adjustment slot.

[0017] As a further improvement of the above technical solution, when the surface cover covers the installation cavity, the inner surface of the surface cover abuts against the top of the adjusting bolt.

[0018] The beneficial effect of the utility model is that, through this scheme, when installing the leakage switch, the adjustment block and the installation beam together with the adjustment bolt can be completely removed from the installation cavity, and then the leakage switch and other parts can be installed on the installation beam, and then the adjustment block is pushed from the outside of the installation cavity into the adjustment slot and the adjustment block is located at the innermost side of the adjustment slot. Then the operator rotates the adjustment bolt so that the bottom of the adjustment bolt abuts against the adjustment base or the inner surface of the installation cavity.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] Reference Figures 1 to 6 A distribution box comprises a distribution box body 10, wherein an installation cavity 11 is arranged in the distribution box body 10, and a surface cover 12 covering the installation cavity 11 is arranged on the distribution box body 10;

[0031] The left and right sides of the installation cavity 11 are both equipped with adjustment bases 20, and two sets of limit plates 21 are arranged along the up-down direction on the surfaces of the two adjustment bases 20 facing each other, and the two sets of limit plates 21 enclose and form an adjustment slot 201 arranged in the inside-outside direction;

[0032] Two adjustment blocks 30, the two adjustment blocks 30 are respectively installed in the adjustment slots 201 on both sides of the installation cavity 11, and the adjustment blocks 30 are provided with bolt holes 31 penetrating the front and back;

[0033] An adjusting bolt 40, wherein the adjusting bolt 40 is threaded into the bolt hole 31 and the bottom of the adjusting bolt 40 is used to abut against the inner surface of the adjusting base 20 or the mounting cavity 11;

[0034] The cross beam 50 is installed, and two ends of the cross beam 50 are respectively fixed on the two adjustment blocks 30 .

[0035] Through this solution, when installing the leakage switch, the adjustment block 30 and the installation beam 50 together with the adjustment bolt 40 can be completely removed from the installation cavity 11, and then the leakage switch and other parts can be installed on the installation beam 50, and then the adjustment block 30 is pushed from the outside of the installation cavity 11 into the adjustment slot 201 and the adjustment block 30 is located at the innermost side of the adjustment slot 201. Then the operator rotates the adjustment bolt 40 so that the bottom of the adjustment bolt 40 abuts against the adjustment base 20 or the inner surface of the installation cavity 11. Since the adjustment bolt 40 cannot be fed inward, the adjustment bolt 40 will drive the adjustment block 30 to move outward along the adjustment slot 201 during the continued rotation. When the distribution switch moves to the appropriate position, the rotation of the adjustment bolt 40 is stopped, thereby completing the installation. Through this method, firstly, it is convenient to install the leakage switch and other parts, and secondly, it is convenient to adjust the depth of the installation beam 50 in the installation cavity 11. The operation is very convenient and can greatly reduce the installation time of the electrician.

[0036] In the above manner, the adjustment block 30 can be abutted and stuck against the inner wall of the adjustment slot 201, or it can be not stuck so that the adjustment block 30 can move freely in the adjustment slot 201. When the adjustment block 30 can move freely in the adjustment slot 201, the innermost position of the adjustment block 30 is limited by the adjusting bolt 40. At this time, the adjustment block 30 can move outward relative to the adjustment slot 201. At this time, preferably, when the surface cover 12 covers the installation cavity 11, the inner surface of the surface cover 12 abuts against the top of the adjusting bolt 40, thereby directly limiting the position of the adjusting bolt 40 after the surface cover 12 is fixed, so that the position of the adjustment block 30 is indirectly fixed.

[0037] In a preferred embodiment, the two sides of the limit plate 21 and / or the adjustment block 30 are preferably elastic so that the inner wall of the limit plate 21 abuts against the surface of the adjustment block 30 and is pressed toward each other, thereby ensuring that the adjustment block 30 does not move arbitrarily in the adjustment slot 201, but requires a certain external force to operate the adjustment block 30, so that the adjustment block 30 has better stability. On this basis, it is preferred that the inner wall of the limit plate 21 is provided with an adjustment wave tooth 211 located on the upper and lower sides of the adjustment slot 201, and the upper and lower surfaces of the adjustment block 30 are provided with a snap position for snapping on the adjustment wave tooth 211. The snap position snaps on the adjustment wave tooth 211, so that the fixing process forms a sense of paragraphs, thereby enhancing feedback, and the fixing is also more stable. Since the adjustment wave tooth 211 is a structure that is constantly undulating, it is preferred that the snap position is a positioning convex rib 33 in this solution. In other embodiments, the snap position can also be in the form of a concave positioning groove. Preferably, the edge of the positioning rib 33 is an arc-shaped surface, so that it is smoother when transitioning from one tooth to another on the adjusting wave tooth 211.

[0038] For further optimization, in the present scheme, the adjustment block 30 preferably includes a main body and elastic side panels 32 which are arranged on the upper and lower sides of the main body and pop out to the outside, and the upper and lower sides of the main body are provided with avoidance spaces 321 for the elastic side panels 32 to deform inwardly, and the engaging position is arranged on the top outer surface of the elastic side panel 32, and the elasticity of the elastic side panel 32 is used to drive the engaging position to move, thereby facilitating production and installation.

[0039] For further optimization, it is preferred that deformation stop plates 34 are further provided on the upper and lower sides of the adjustment block 30, and the edge of the deformation stop plate 34 is located at the front end of the engagement position. The maximum distance between the edges of the deformation stop plates 34 on both sides of the adjustment block 30 is smaller than the minimum width of the adjustment slot 201. The deformation stop plate 34 limits the inward deformation amplitude of the elastic side plate 32, thereby providing a certain protection for the elastic side plate 32.

[0040] Since the elastic side plate 32 is used to achieve elastic deformation, on this basis, the adjustment base 20 also includes a bottom plate 22 and an outer plate 23. The bottom of the limit plate 21 is fixed to the bottom plate 22, and the outer side of the limit plate 21 is fixed to the outer plate 23. The bottom plate 22 is provided with a fixing position fixed to the inner wall of the installation cavity 11, so that the adjustment base 20 forms a relatively rigid state, which makes the adjustment base 20 stronger, has a longer service life, and is easier to produce. Preferably, the inner wall of the outer plate 23 is provided with reinforcing ribs 231 arranged along the front-to-back direction, so as to strengthen the strength of the adjustment base 20, and the reinforcing ribs 231 can also reduce the contact area between the adjustment block 30 and the outer plate 23, thereby reducing the friction.

[0041] In other embodiments, the two groups of limiting plates 21 may also be elastically deformed on the adjustment base 20 toward the inner side of the adjustment slot 201 , so as to be pressed tightly against the upper and lower sides of the adjustment block 30 .

[0042] In this solution, it is preferred that a mounting slot 35 is provided in the middle of the adjustment block 30 , and both ends of the mounting crossbeam 50 are movably inserted into the mounting slot 35 , so as to facilitate the installation of the mounting crossbeam 50 .

[0043] Preferably, both ends of the mounting crossbeam 50 are provided with through positioning holes 51 which are synchronously sleeved on the outer circumference of the adjusting bolt 40 , so that the adjusting bolt 40 also plays a role in fixing the mounting crossbeam 50 to prevent the mounting crossbeam 50 from falling off.

[0044] In other embodiments, the bottom of the adjusting bolt 40 may be rotatably fixed to the box or the adjusting base 20 , so that the adjusting block 30 cannot be separated from the mounting cavity 11 .

[0045] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
