Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example (b): referring to fig. 1 and 2, a sealing door on high tension apparatus switch board, includes rectangular door plant 1, establishes at the square frame 11 of door plant 1 inboard, and frame 11 flushes with the edge of door plant 1, sets up annular sealing strip 2 in the inboard of frame 11, slides in one side of sealing strip 2 and sets up clamp plate 3, and sealing strip 2 is located between clamp plate 3 and the frame 11, and clamp plate 3 is used for supporting sealing strip 2 tightly on frame 11. When door plant 1 installed on the block terminal body, 2 elasticity of sealing strip contradict on the side of block terminal body this moment to with on the clearance shutoff between door plant 1 and the block terminal body, improve the leakproofness between door plant 1 and the block terminal body.
Referring to fig. 2 and 3, a plurality of L-shaped plates 5 are fixedly disposed on the door panel 1 in a direction perpendicular to the pressing plate 3, and the pressing plate 3 is slidably connected between the L-shaped plates 5 and the door panel 1, so as to restrict the pressing plate 3 from being separated from the door panel 1. Set up the locking device 4 that is used for locking clamp plate 3 on L shaped plate 5, locking device 4 includes a plurality of along the direction of perpendicular to clamp plate 3 and respectively threaded connection is at the pole 40 that supports on L shaped plate 5, when rotating to support pole 40, supports pole 40 and contradicts on clamp plate 3, further makes clamp plate 3 extrusion sealing strip 2 to press from both sides sealing strip 2 tightly between frame 11 and clamp plate 3, prevent that sealing strip 2 and door plant 1 from breaking away from. A nut 41 is welded to the L-shaped plate 5, and the abutment bar 40 is screwed into the nut 41. Since the L-shaped plate 5 is formed by bending and is relatively thin, the nut 41 is provided to increase the length of the screw-thread fit of the holding rod 40.
Referring to fig. 2, a positioning plate 6 is arranged between a pressing plate 3 and a frame 11 on a door panel 1, semicircular limiting blocks 61 are arranged on two side surfaces of the positioning plate 6, and a sealing strip 2 is inserted into the positioning plate 6. At first with the grafting of sealing strip 2 interference on locating plate 6 for sealing strip 2 occupies accurate position on door plant 1, and the setting of stopper 61 prevents that sealing strip 2 from breaking away from locating plate 6 simultaneously.
Referring to fig. 2, a rib 31 is arranged on the side surface of the pressing plate 3 close to the sealing strip 2 along the length direction of the sealing strip 2, a limiting groove 21 matched with the rib 31 is formed in the sealing strip 2, when the rib 31 is matched in the limiting groove 21, the sealing strip 2 is further limited from being separated from the pressing plate 3 and the frame 11, and the firmness of the sealing strip 2 is improved. One side that door plant 1 was kept away from to sealing strip 2 establishes to the arc surface, and when sealing strip 2 contradicted on the block terminal body, can warp, the arc surface makes sealing strip 2 can extend to both sides at compression deformation's in-process to make the better laminating of sealing strip 2 and block terminal body.
The action process is as follows: firstly, the sealing strip 2 is inserted into the positioning plate 6, then the pressing rod 40 is rotated, so that the pressing plate 3 is extruded by the pressing rod 40, and the sealing strip 2 is tightly pressed between the pressing plate 3 and the frame 11 by the pressing plate 3, so that the installation of the sealing strip 2 is completed; when the sealing strip 2 needs to be replaced, the abutting rod 40 rotates reversely, the abutting rod 40 is far away from the pressing plate 3, then the pressing plate 3 is separated from the sealing strip 2, and finally the sealing strip 2 is pulled out from the positioning plate 6.
Referring to fig. 5 and 6, a groove 51 matched with the driving rod 43 is formed in the L-shaped plate 5, after the elliptical shaft 42 rotates by a certain angle, the sealing strip 2 is abutted against the frame 11, at this time, the distance between the pressing plate 3 and one end, far away from the pressing plate 3, of the L-shaped plate 5 is the largest, meanwhile, the driving rod 43 is just located on one side of the groove 51, the elliptical shaft 42 slides, the driving rod 43 is matched in the groove 51, and at this time, the elliptical shaft 42 cannot rotate, so that the elliptical shaft 42 is locked. A fixing plate 44 is provided on one side of the driving rod 43, the fixing plate 44 is welded to the door panel 1, and a spring 45 is provided between the fixing plate 44 and the driving rod 43. One end of the spring 45 is welded to the fixing plate 44, and the other end abuts against the driving rod 43. When the driving rod 43 is located in the groove 51, the spring 45 abuts against the driving rod 43 to prevent the driving rod 43 from being separated from the groove 51, and further prevent the elliptical shaft 42 from rotating during the opening and closing of the door panel 1.
The action process is as follows: firstly, the sealing strip 2 is inserted into the positioning plate 6, then the elliptical shaft 42 is rotated, so that the driving rod 43 is matched in the groove 51, and at the moment, the sealing strip 2 is tightly pressed between the pressing plate 3 and the frame 11 by the pressing plate 3, so that the sealing strip 2 is installed; when the sealing strip 2 needs to be replaced, the elliptical shaft 42 is rotated reversely, so that the pressing plate 3 is separated from the sealing strip 2, and finally the sealing strip 2 is pulled out from the positioning plate 6.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
