Abstract
Description
Technical Field
[0001] The utility model relates to an instrument door which can prevent vertical water dripping and belongs to the technical field of electrical equipment. Background Art
[0002] In order to prevent condensation dripping and pipe dripping from endangering the safety of electricity use, humid environments such as underground distribution rooms generally require that the distribution equipment can reach the IPX1 waterproof level, that is, the distribution equipment can prevent vertical dripping from invading the distribution equipment and causing damage to the electrical components. For electrical components installed on door panels, in order to achieve the IPX1 waterproof level, the general practice is to use special protective covers to isolate the electrical components according to the model or size of the electrical components. However, this solution requires adjusting the protective covers according to the type and quantity of the electrical components on the door panels. Not only are there many types, but the production cost is also high. Utility Model Content
[0003] The purpose of the utility model is to propose an instrument door that prevents vertical dripping, in view of the problems existing in the prior art, to meet the requirements of waterproof level and to ensure assembly standardization.
[0004] In order to achieve the above purpose, the utility model provides an instrument door that prevents vertical dripping, including a door body, an instrument installation box is fixed on the back of the door body, and a protective door plate is provided on the front of the door body corresponding to the position of the instrument installation box. No special protective cover is required. After the protective door plate is closed, the above structure can isolate electrical components such as instruments from the outside, thereby preventing vertical dripping.
[0005] Furthermore, the front of the door body is provided with a square hole adapted to the protective door panel, so that the protective door panel can be just embedded in the door body when closed, and the back of the door body is provided with welding screws around the square hole to facilitate fixing the instrument mounting box.
[0006] A hinge fixing hole is arranged on one side of the square hole. A hinge matching the hinge fixing hole is arranged on one side of the protective door plate, and a door lock is arranged on the other side for opening, closing and locking the protective door plate.
[0007] The front of the instrument installation box is provided with fixing holes matched with welding screws and clearance holes matched with hinge fixing holes to avoid interference between hinge fixing screws and the instrument installation box. The back of the instrument installation box is provided with at least one set of instrument holes adapted to the instrument, and the number and size of the openings can be determined according to actual needs to install electrical components such as instruments.
[0008] The utility model has a simple structure and is easy to process. It has the beneficial effects of meeting the requirements of waterproof grade and having a high degree of standardization. It does not need to frequently change the external dimensions, and only needs to adjust the size and number of the openings according to project requirements, and is suitable for popularization and use.

[0021] Example
[0022] The structure of this embodiment is as follows Figure 1-12As shown, an instrument door that prevents vertical dripping includes a door body 1, an instrument installation box 3 is fixed on the back of the door body 1, and a protective door panel 2 is provided on the front of the door body 1 corresponding to the position of the instrument installation box 3. The door body 1 is formed by bending a sheet metal material, and a square hole 1-1 is provided on the front, and the size of the opening matches the outer size of the protective door panel 2, so that the protective door panel 2 can be just embedded in the door body 1 when closed; welding screws 1-2 are provided around the square hole 1-1 on the back, and their positions match the installation holes 3-1 on the front of the instrument installation box 3, which are used to fix the instrument installation box 3; hinge fixing holes 1-3 are provided on the side of the square hole 1-1, and the position and size match the hinge 2-1 on the side of the protective door panel 2, so that the protective door panel 2 can be just embedded in the door body 1 when closed. The protective door panel 2 is formed by bending sheet metal material, with a hinge 2-1 provided on the front side, cooperating with the hinge mounting hole 1-3 in the door body 1 to open and close the protective door panel 2; a door lock 2-2 is provided on the front side to lock the protective door panel 2 after it is closed. The instrument installation box 3 is formed by bending sheet metal material, with a fixing hole 3-1 provided on the front side, cooperating with the welding screw 1-2 on the back of the door body 1 to fix the instrument installation box 3 on the back of the door body 1; a clearance hole 3-2 is provided on the front side, and its position corresponds to the hinge fixing hole 1-3 on the side of the door body 1 to avoid interference between the hinge fixing screw and the instrument installation box 3; an instrument hole 3-3 is provided on the back, and the number and size of the holes are determined according to actual needs, and are used to install electrical components such as instruments, such as Figure 1 As shown, the protective door panel 2 has an open state A and a closed state B. When the protective door panel 2 is in the closed state B, electrical components such as instruments are isolated from the outside, thereby preventing vertical dripping.
[0023] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
