Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a switch cabinet door opening fixing support device. Background Art

[0002] A switchgear is an electrical equipment cabinet whose main function is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and energy conversion in the power system.

[0003] At present, in the application of switch cabinets, there is no support between the switch cabinet and the switch cabinet body after the switch cabinet door is opened. When the cabinet is operated and maintained with the door open, the secondary wires and other accessories on the door will cause the door to reset, and the door will hit the operator, which poses certain hidden dangers. At the same time, there is a lack of buffer between the door panel and the cabinet body, which causes the door panel to directly collide with the switch cabinet after being hit, reducing the service life of the door panel.

[0004] Therefore, there is an urgent need for a device that can fix and support the door panel when the switch cabinet door is opened. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that when the cabinet is operated and repaired in the open door state, the secondary wires and other accessories on the door cause the door to reset and hit the operator, and proposes a switch cabinet door opening fixing support device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The lock mechanism is used to lock the locking cam and the locking cam, and the locking cam is used to lock the locking cam of the locking cam, and the locking cam is used to lock the locking cam of the locking cam.

[0008] In order to better achieve the above-mentioned purpose, the utility model adopts a further technical solution: the upper support rod and the lower support rod are both rotatably mounted on the fixing pin.

[0009] In order to better achieve the above-mentioned purpose, the utility model adopts a further technical solution: when the door panel is in an open state, the ends of the upper support rod and the lower support rod away from the fixing pin are in a fitted state.

[0010] In order to better achieve the above-mentioned purpose, the utility model adopts a further technical solution: the support block is installed on the cabinet through a telescopic rod.

[0011] In order to better achieve the above-mentioned purpose, the utility model adopts a further technical solution: when the door panel swings away from the cabinet body, the abutment plate locks the ratchet gear.

[0012] The advantages of the utility model are: by arranging a supporting mechanism, when the cabinet is opened, the elastic force of the first spring is used to naturally prop up the upper supporting rod and the lower supporting rod, so that the door panel is always kept in an open state, and the door panel is prevented from resetting and bumping against the staff during operation and maintenance. The switch cabinet can be opened safely and quickly, and the work efficiency is improved. At the same time, when the cabinet is closed, the stretching of the first spring can buffer the hard collision between the door panel and the cabinet, so as to avoid damage to the door panel and extend the service life of the door panel; by arranging a locking mechanism, when the cabinet is closed, the door panel is swung to be close to the cabinet, and the elastic force of the second spring is used to make the abutment plate swing upward and jam the ratchet gear, so that the door panel cannot swing away from the cabinet. The cabinet can be automatically closed by swinging the door panel to a specified position, and the operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Reference Figure 1-Figure 4 As shown, a switch cabinet door opening fixing support device comprises: a cabinet body 1, hinge seats 11 are provided on both sides of the cabinet body 1, and door panels 12 are hinged on the two hinge seats 11; a support mechanism 2, the support mechanism 2 is used to prevent hard collision between the door panel 12 and the cabinet body 1, and comprises an upper support rod 21 and a lower support rod 22 rotatably installed on the door panel 12 and the cabinet body 1, the upper support rod 21 and the lower support rod 22 are connected by a fixing pin 23, the upper support rod 21 and the lower support rod 22 are provided with countersunk screws 24, and the two countersunk screws 24 are elastically connected by a first spring 25, the upper support rod 21 and the lower support rod 22 are rotatably installed on the fixing pin 23, and when the door panel 12 is in an open state, the ends of the upper support rod 21 and the lower support rod 22 away from the fixing pin 23 are in a fitted state, thereby preventing the door panel 12 from being excessively opened and occupying too much space.

[0020] In view of the problem in the prior art that there is no support between the switch cabinet and the switch cabinet body after the door is opened, and the cabinet body 1 is operated and repaired in the open state, the door will be reset due to the secondary wires and other accessories on the door, and the door will hit the operator, which poses certain hidden dangers. The utility model provides a support mechanism 2. When the cabinet body 1 is opened, the elastic force of the first spring 25 naturally props up the upper support rod 21 and the lower support rod 22, so that the door panel 12 is always in the open state, and the door panel 12 is prevented from resetting and hitting the staff during operation and maintenance. The switch cabinet can be opened safely and quickly, and work efficiency is improved. At the same time, when the cabinet body 1 is closed, the stretching of the first spring 25 can buffer the hard collision between the door panel 12 and the cabinet body 1, avoid damage to the door panel 12, and extend the service life of the door panel 12.

[0021] The locking mechanism 3 is used to automatically close the cabinet 1, and includes a support block 31 installed above the cabinet 1. An abutment plate 33 is rotatably installed on the support block 31 through a mounting block 32. The abutment plate 33 is elastically connected to the support block 31 through a second spring 34. A ratchet gear 35 is provided at one end of the door panel 12 shaft close to the abutment plate 33, and the abutment plate 33 and the ratchet gear 35 cooperate with each other.

[0022] When the door panel 12 swings away from the cabinet 1 , the abutment plate 33 blocks the ratchet gear 35 , and the support block 31 is installed on the cabinet 1 through the telescopic rod 4 .

[0023] After the operation and maintenance is completed, the door panel 12 is swung to be close to the cabinet body 1. The elastic force of the second spring 34 causes the abutment plate 33 to swing upward and jam the ratchet gear 35, so that the door panel 12 cannot swing away from the cabinet body 1. The cabinet body 1 can be automatically closed by simply swinging the door panel 12 to the specified position, which makes the operation more convenient. When the cabinet body 1 needs to be opened, the support block 31 can be moved downward under the action of the telescopic rod 4, so that the abutment plate 33 no longer jams the ratchet gear 35.

[0024] When the cabinet 1 is opened, the upper support rod 21 and the lower support rod 22 are naturally propped up by the elastic force of the first spring 25, so that the door panel 12 is always in the open state, and the door panel 12 is prevented from resetting and hitting the staff during operation and maintenance. The switch cabinet can be opened safely and quickly, and the work efficiency is improved. At the same time, when the cabinet 1 is closed, the stretching of the first spring 25 can buffer the hard collision between the door panel 12 and the cabinet 1, and damage to the door panel 12 is avoided. After the operation and maintenance is completed, the door panel 12 is swung to be close to the cabinet 1, and the elastic force of the second spring 34 is used to make the abutment plate 33 swing upward and jam the ratchet gear 35, so that the door panel 12 cannot swing away from the cabinet 1. The cabinet 1 can be automatically closed by swinging the door panel 12 to the specified position, and the operation is more convenient.
