Description

Technical Field

[0001] The utility model relates to the field of mechanical structures, in particular to a punching plate hole sealing device. Background Art

[0002] Partitions are generally provided in electrical cabinet equipment to separate different application scenarios. When there is an aquifer above the partition and an electronic equipment layer below, the circuit of the electronic equipment needs to pass through the opening of the partition from the upper layer to the lower layer. At this time, the sealing of the opening of the partition is particularly important. The existing technology often adopts welding metal pipes on the upper part of the opening, and the lines are directly penetrated by the pipes and lead to the lower layer. First, this method will destroy the existing structural integrity of the partition, resulting in irreversible consequences. Secondly, the aging and rusting of the welding structure will seriously affect the safety of the equipment. Summary of the invention

[0003] Purpose of the utility model: In order to overcome the shortcomings of the background technology, the purpose of the utility model is to disclose a punching plate hole sealing device.

[0004] Technical solution: The punching plate hole sealing device disclosed in the utility model comprises an internal threaded cylinder and an external threaded cylinder;

[0005] The internal threaded cylinder is pressed against one side of the hole of the punching plate, and comprises an internal threaded cylinder body and an internal threaded pressing plate formed by a convex outer periphery of one end close to the punching plate;

[0006] The externally threaded barrel component includes an externally threaded barrel body and an externally threaded pressure plate formed by a protrusion on the outer periphery of one end of the externally threaded barrel body. The externally threaded barrel body passes through the other side of the hole of the punching plate and is screwed to the internally threaded barrel body until the externally threaded pressure plate is pressed against the punching plate. The externally threaded barrel body and the externally threaded pressure plate are hollow through structures for wiring.

[0007] Furthermore, the axial ends of the internal thread pressure plate and the external thread pressure plate pressed against the punching plate are both provided with rubber pad grooves, and a first rubber gasket is provided in the rubber pad groove. As the internal thread tube body and the external thread tube body are tightened, the first rubber gaskets on both sides form a seal on the outer periphery of the hole of the punching plate.

[0008] Furthermore, the internal thread pressing plate and the external thread pressing plate are both provided with a second rubber gasket at a radially outer interval of the first rubber gasket, so as to form further sealing protection on the outer periphery of the first rubber gasket.

[0009] Furthermore, the outer contour of the internally threaded barrel body and the axial outer end of the externally threaded pressure plate are both prismatic structures that are easy to rotate and bear force.

[0010] Furthermore, the internally threaded cylinder and the externally threaded cylinder are both made of plastic.

[0011] Beneficial effects: Compared with the prior art, the advantages of the utility model are:

[0012] 1. It can form a better seal at the punching hole;

[0013] 2. Easy to disassemble and install;

[0014] 3. The wiring harness can pass through without obstacles;

[0015] 4. It has good supporting performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of the structure of the utility model;

[0017] Figure 2 This is a rendering of the use of the utility model. DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 and 2 The punching plate hole sealing device shown comprises an internal threaded cylinder 1 and an external threaded cylinder 2, both of which are made of plastic.

[0020] The internal threaded cylinder 1 is pressed against one side of the hole of the punching plate, and comprises an internal threaded cylinder body 101 and an internal threaded pressing plate 102 formed by a protrusion on the outer periphery of one end close to the punching plate.

[0021] The externally threaded barrel member 2 includes an externally threaded barrel body 201 and an externally threaded pressing plate 202 formed by a peripheral protrusion at one end of the externally threaded barrel body 201. The externally threaded barrel body 201 passes through the other side of the hole of the punching plate and is screwed to the internally threaded barrel body 101, until the externally threaded pressing plate 202 is pressed against the punching plate. The externally threaded barrel body 201 and the externally threaded pressing plate 202 are hollow through structures for wiring, which not only achieve sealing at the punching hole, but also facilitate disassembly and installation.

[0022] The axial ends of the internal thread pressing plate 102 and the external thread pressing plate 202 pressed against the punching plate are both provided with rubber gasket grooves, and a first rubber gasket 3 is arranged in the rubber gasket groove. As the internal thread cylinder body 101 and the external thread cylinder body 201 are tightened, the first rubber gaskets 3 on both sides form a seal on the outer periphery of the hole of the punching plate. The internal thread pressing plate 102 and the external thread pressing plate 202 are both provided with a second rubber gasket 4 at the radial outer side interval of the first rubber gasket 3, forming further sealing protection on the outer periphery of the first rubber gasket 3, and the sealing performance is increased by double-layer sealing.

[0023] The outer contour of the internally threaded barrel body 101 and the axial outer end of the externally threaded pressing plate 202 are both prismatic structures that are easy to rotate and bear force, and are used to bear force during disassembly and installation.
