Description

Technical Field

[0001] This application relates to the technical field of electrical cabinet door sealing, and more particularly to a V-type sealing device for electrical cabinet doors. Background Technology

[0002] Currently, there are two main types of sealing devices for electrical cabinet doors: one is the use of asbestos rope compression sealing. This type of sealing has problems such as the asbestos rope easily falling off during door opening and closing and aging easily during operation, resulting in a large workload for operation and maintenance and poor sealing effect; the other is the use of rubber gasket compression sealing. This type of sealing has problems such as the rubber gasket aging quickly outdoors and easily losing its sealing effect, resulting in a large workload for operation and maintenance and poor sealing effect.

[0003] Therefore, in order to address the above problems, there is an urgent need to develop a more stable and reliable electrical cabinet door sealing device. Utility Model Content

[0004] This application provides a V-shaped sealing device for electrical cabinet doors to solve the technical problems of existing electrical cabinet door sealing devices, which have the problems of easy detachment and aging of sealing materials, resulting in reduced sealing performance, poor sealing effect, and increased workload of operation and maintenance.

[0005] In view of this, this application provides a V-shaped sealing device for an electrical cabinet door, including a V-shaped groove and a circular silicone sealing strip. The V-shaped groove is disposed on the electrical cabinet door frame, and the circular silicone sealing strip is disposed on the electrical cabinet door. When the electrical cabinet door is closed, the V-shaped groove and the circular silicone sealing strip are used to press the circular silicone sealing strip into the V-shaped groove to create an interference fit seal when the electrical cabinet door is connected to the electrical cabinet door frame by screws.

[0006] Optionally, the V-shaped slot is fixed to the electrical cabinet door frame by spot welding.

[0007] Optionally, the circular silicone sealing strip is fixed to the electrical cabinet door by adhesive bonding.

[0008] Optionally, threaded holes are provided at the four corners of the electrical cabinet door frame, and threaded through holes are provided at the four corners of the electrical cabinet door. The threaded through holes and the threaded holes are connected by screws.

[0009] Optionally, the V-shaped groove is a stainless steel V-shaped groove.

[0013] Optionally, the water guide plate is placed on the upper end face of the top plate, and the bottom surface of the water guide plate is fixedly connected to the upper end face of the top plate.

[0014] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0015] This application provides a V-shaped sealing device for electrical cabinet doors. It utilizes a V-shaped groove and a circular silicone sealing strip. The V-shaped groove is positioned on the electrical cabinet door frame, and the circular silicone sealing strip is positioned on the electrical cabinet door. When the electrical cabinet door is closed, the door is connected to the door frame by screws, causing the circular silicone sealing strip to be pressed into the V-shaped groove, creating an interference fit seal. This ensures that when the electrical cabinet door is closed, the circular silicone sealing strip accurately enters the V-shaped groove. Under the pressure generated by tightening the door, the circular silicone sealing strip undergoes slight deformation, making tight contact with the V-shaped groove to form a mechanical seal. Simultaneously, the space formed at the bottom of the V-shaped groove further restricts airflow, enhancing the sealing effect. Furthermore, based on the elastic coefficient and wear resistance of silicone material, the sealing performance of the electrical cabinet door remains stable over a long period. This device is applicable to sealing different types of electrical cabinet doors.

[0016] The electrical cabinet has a top cover, which includes a horizontally positioned top plate and a water guide plate with downward-sloping edges. The water guide plate is placed on the upper surface of the top plate, and the bottom surface of the water guide plate is fixedly connected to the upper surface of the top plate, thereby guiding rainwater and improving the rainproof effect of the electrical cabinet.

[0026] For easier understanding, please refer to Figures 1 to 3This application provides an embodiment of a V-shaped sealing device for an electrical cabinet door 3, comprising a V-shaped groove 7 and a circular silicone sealing strip 8. The V-shaped groove 7 is disposed on the electrical cabinet door frame 2, and the circular silicone sealing strip 8 is disposed on the electrical cabinet door 3. When the electrical cabinet door 3 is closed, the electrical cabinet door 3 is connected to the electrical cabinet door frame 2 by screws 9, causing the circular silicone sealing strip 8 to be pressed into the V-shaped groove 7 to create an interference fit seal. This ensures that when the electrical cabinet door 3 is closed, the circular silicone sealing strip 8 accurately enters the V-shaped groove 7. Under the pressure generated by tightening the door, the circular silicone sealing strip 8 undergoes slight deformation, making close contact with the V-shaped groove 7 to form a mechanical seal. At the same time, the space formed at the bottom of the V-shaped groove 7 further prevents airflow, enhancing the sealing effect. Based on the elastic coefficient and wear resistance characteristics of silicone material, the sealing performance of the electrical cabinet door 3 is ensured to be stable over a long period of time, and it can be used for sealing different types of electrical cabinet doors 3.

[0027] Furthermore, the V-shaped groove 7 is fixed to the electrical cabinet door frame 2 by spot welding, thereby improving the stability of the V-shaped groove 7 on the electrical cabinet door frame 2, improving the durability of the V-shaped groove 7, and facilitating close contact between the circular silicone sealing strip 8 and the V-shaped groove 7 when the electrical cabinet door 3 is closed, thus improving the sealing performance of the electrical cabinet door 3.

[0028] Furthermore, the circular silicone sealing strip 8 is fixed to the electrical cabinet door 3 by adhesive bonding, thereby improving the stability of the connection between the circular silicone sealing strip 8 and the electrical cabinet door 3, preventing the circular silicone sealing strip 8 from easily falling off the electrical cabinet door 3, improving the durability of the circular silicone sealing strip 8, and thus improving the sealing performance of the electrical cabinet door 3.

[0029] Furthermore, threaded holes 11 are provided at the four corners of the electrical cabinet door frame 2, and threaded through holes 10 are provided at the four corners of the electrical cabinet door 3. The threaded through holes 10 and the threaded holes 11 are connected by screws 9. When the electrical cabinet door 3 is closed, the screw 9 nut is rotated so that the insertion end of the screw 9 passes through the threaded through hole 10 and enters the threaded hole 11, thereby closing the electrical cabinet door 3.

[0030] Furthermore, the V-shaped groove 7 is a stainless steel V-shaped groove 7, which is not easy to rust, further improving the durability of the V-shaped groove 7.

[0031] Furthermore, the stainless steel V-shaped groove 7 is press-formed during the processing of the electrical cabinet door frame 2, which improves the stability of the stainless steel V-shaped groove 7.

[0032] Furthermore, the electrical cabinet 1 is provided with a top cover, which is used to protect the electrical cabinet 1 from rain and prevent rainwater from directly hitting the top of the electrical cabinet 1 and invading the electrical cabinet 1, thereby improving the rainproof performance of the electrical cabinet 1. The electrical cabinet 1 is provided with legs 6 at the four corners of the bottom, which are used to raise the bottom of the electrical cabinet 1 and prevent the bottom of the electrical cabinet 1 from being in direct contact with the ground for a long time, which could easily cause damage.

[0033] Furthermore, the top cover includes a horizontally arranged top plate 4 and a water guide plate 5 with downwardly angled edges. The top is used to connect the water guide plate 5 to the top of the electrical cabinet 1. The water guide plate 5 is used to facilitate the rapid diversion of rainwater that falls on it to the two side edges, so that the rainwater is quickly diverted to the ground, avoiding the accumulation of rainwater on the top cover and improving the rainproof performance of the electrical cabinet 1.

[0034] Furthermore, the water guide plate 5 is placed on the upper surface of the top plate 4, and the bottom surface of the water guide plate 5 is fixedly connected to the upper surface of the top plate 4, which improves the stability of the water guide plate 5.

[0035] Working principle:

[0036] When the electrical cabinet door 3 is closed, the screw 9 nut is turned so that the insertion end of the screw 9 passes through the threaded through hole 10 and enters the threaded hole 11. At this time, the circular silicone sealing strip 8 accurately enters the V-shaped groove 7. Under the pressure generated by the door being tightened and closed, the circular silicone sealing strip 8 undergoes a slight deformation and comes into close contact with the V-shaped groove 7, forming a mechanical seal. At the same time, the space formed at the bottom of the V-shaped groove 7 further prevents the flow of air and enhances the sealing effect. Based on the elastic coefficient and wear resistance of silicone material, the sealing performance of the electrical cabinet door 3 can be ensured to be stable for a long time and can be used for sealing different types of electrical cabinet doors 3.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
