Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box with a cover plate that can be positioned when opened. Background Art

[0002] Distribution boxes are widely used due to their small footprint and light weight. In actual use, conventional distribution boxes are fixed with bolts, and circuit breakers and wiring devices are installed inside.

[0003] Publication No. CN219959821U discloses a cover plate for a distribution box, including a cover plate body, a rotating rod is arranged at the upper end of the cover plate body, a fixed plate is arranged on one side of the cover plate body, a second fixed block is arranged on one side of the fixed plate, a wiping cotton is arranged on one side of the second fixed block, a mounting groove is arranged inside the cover plate body, two snap plates are symmetrically arranged inside the mounting groove, and a mounting column is arranged on one side of the snap plate. This cover plate is hinged to the distribution box through hinges and rotating rods. Although this structure can meet the swing of the cover plate body on the distribution box (to achieve opening or closing), the positioning effect is poor, that is, when the cover plate is opened and reaches a state that does not interfere with the user's use, the state cannot be maintained by relying solely on the friction force generated by the contact between the hinge and the rotating rod, that is, the cover plate body will involuntarily swing in the closing direction, so when it is necessary to repeatedly control the opening or closing of the circuit breaker, it is necessary to repeatedly open the cover plate body, and this process is too cumbersome.

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Referring to the accompanying drawings: a distribution box with a cover that can be positioned when opened, comprises a box body 1, a protective panel 2 arranged at the open part of the box body 1, and a cover plate 3 hinged on the protective panel 2, the protective panel 2 comprises a box body cover portion 21 that covers the box body 1, and an extension portion 22 that extends from the box body cover portion 21 and is used to combine with the cover plate 3, two left-right symmetrically distributed first installation cavities 4 and a second installation cavity 5 located between the two first installation cavities 4 are arranged at the upper end long axis portion of the extension portion 22, a hinge assembly 6 is arranged between the first installation cavity 4 and the cover plate 3, the cover plate 3 is hinged to the protective panel 2 through the hinge assembly 6, and a positioning assembly 7 with an adjustable length is arranged in the second installation cavity 5, and the positioning assembly 7 keeps the cover plate 3 in an open state after it is opened. The principle of the utility model is that the protection panel 2 is so set that it can be combined with the box body 1 and the cover plate 3. The cover plate 3 is hingedly set on the protection panel 2 by the hinge assembly 6, so as to realize the opening or closing of the cover plate 3, and after the cover plate 3 is opened, the positioning assembly 7 can be used to keep the open state of the cover plate 3, so as to avoid interference to the user due to insufficient opening angle of the cover plate 3 when the user is working, and there is no need to repeatedly open the cover plate 3, so as to facilitate the user to operate the circuit breaker.

[0022] The first installation cavity 4 is provided with a first front opening 41 and a first upper opening 42 in the extension portion 22. The first front opening 41 allows partial components of the hinge assembly 6 arranged in the first installation cavity 4 to enter the first installation cavity 4, and the first upper opening 42 allows the partial components of the hinge assembly 6 placed in the first installation cavity 4 to extend upward out of the first installation cavity 4 and be hinged to the partial components of the hinge assembly 6 arranged on the cover plate 3. Such a configuration facilitates the installation of partial components of the hinge assembly 6 in the first installation cavity 4, and also allows the partial components placed in the first installation cavity 4 to be exposed outside the first installation cavity 4, so that they can be hinged to the partial components of the hinge assembly 6 arranged on the cover plate 3.

[0023] The hinge assembly 6 includes a hinge 61 and a shaft 62. The hinge 61 enters the first installation cavity 4 from the first front opening 41 and is fixed in the first installation cavity 4 by bolts. The first upper end opening 42 allows part of the hinge 61 to extend upward out of the first installation cavity 4, and the upper end of the extended hinge 61 is bent to form an axial hole 61-a by bending. The shaft 62 is arranged on the cover plate 3 and axially connected to the axial hole 61-a. The hinge 61 is arranged in the first installation cavity 4, and the shaft 62 is arranged on the cover plate 3, so that the cover plate 3 can swing when the hinge 61 and the shaft 62 are axially connected. The axial hole 61-a on the hinge 61 for axially connecting with the shaft 62 does not need to be obtained by processing, that is, it is only necessary to bend the upper end of the hinge 61, and the circular configuration presented by the shaft hole 61-a does not need to be a regular circle, as long as it does not interfere with the rotation of the shaft 62, thereby reducing the difficulty of molding.

[0024] An arc-shaped limit groove 21-a is provided on the upper long axis portion of the box body cover 21. The arc-shaped limit groove 21-a allows part of the cover plate 3 to be placed inside when the cover plate 3 is opened, and the angle of the cover plate 3 after opening can be quickly confirmed through the arc amplitude. The arc-shaped limit groove 21-a extends from the inner upper to the outer lower direction. Under the action of the arc-shaped limit groove 21-a, the upper long axis portion of the box body cover 21 is formed with different dimensional thicknesses, that is, the arc shape reduces the thickness of the upper section of the upper long axis portion by about half, the thickness of the middle section of the upper long axis portion is reduced by about two-thirds, and the thickness of the lower section of the upper long axis portion gradually reduces the reduction in thickness and keeps consistent with the thickness of the box body cover 21. After the thickness is kept consistent, contact interference can be generated between the cover plate 3, thereby preventing the cover plate 3 from continuing to swing after being opened to the desired angle, thereby also being able to quickly confirm the angle of the cover plate 3 after opening.

[0025] The second installation cavity 5 is provided with a second front opening 51 and a second upper opening 52 in the extension portion 22. The second front opening 51 allows the positioning component 7 to enter the second installation cavity 5. The second upper opening 52 allows the positioning component 7 placed in the second installation cavity 5 to extend its own length upward out of the second installation cavity 5 and abut against the cover plate 3. Such a setting facilitates the installation of the positioning component 7 and will not interfere with the positioning component 7 extending out of the second installation cavity 5 after changing its own length, thereby achieving the purpose of providing support for the cover plate 3.

[0026] The positioning assembly 7 includes a fixed section 71 and a plurality of telescopic sections 72. The fixed section 71 is placed in the second mounting cavity 5 and is rotatably connected to the inner wall of the second mounting cavity 5. The telescopic sections 72 are telescopically matched with the fixed section 71, and adjacent telescopic sections 72 are telescopically matched with each other. Such an arrangement enables the positioning assembly 7 to be hidden in the second mounting cavity 5 by telescoping when no positioning support is provided for the cover plate 3, so that it will not interfere with the closing of the cover plate 3. When providing support for the cover plate 3, the length of the positioning assembly 7 is extended by telescoping, that is, support is provided to the cover plate 3 by increasing the length, and the operation is also more convenient.

[0027] When the positioning assembly 7 is fully extended by telescoping, a positioning plug 72-a is provided at the upper end of the telescopic section 72 located at the top, and a positioning slot 31 is provided on the cover plate 3 for part of the positioning plug 72-a to be inserted therein. After the positioning plug 72-a is inserted into the positioning slot 31, the positioning slot 31 uses its own space to confine the positioning plug 72-a therein, and combines with the reaction force that the cover plate 3 will generate after opening to cause itself to close, so as to avoid the positioning plug 72-a from being separated from the positioning slot 31, thereby increasing the supporting stability of the positioning assembly 7 on the cover plate 3 and maintaining the open state of the cover plate 3.

[0028] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
