Detailed Description
The instrument case of the present invention for facilitating the assembly and disassembly of electrical components will be further described with reference to fig. 1 to 4.
The utility model provides a quick-witted case for instrument and meter convenient to electrical components dismouting which characterized by: including box 1, card strip structure 2, locating pin subassembly 4 and mounting panel 3.
The box body 1 consists of a bottom plate 14, an upper plate 11, a left plate 12, a right plate 13, a rear plate 15 and a front door plate 16, wherein the front door plate 16 is a door body of the box body 1 and is used for opening and closing the box body 1.
The clamping strip structures 2 are provided with two groups and are respectively arranged on two corresponding inner walls of the box body 1, and are respectively arranged on the inner walls of the upper plate 11 and the inner walls of the bottom plate 14 in the embodiment, and can be specifically arranged on the corresponding inner walls according to actual requirements. Each group of clamping strip structures 2 comprises clamping strips 22 and sliding rails 21; the slide rail 21 in each group of the clamping strip structures 2 is provided with two slide rails which are respectively fixed on the inner wall of the box body 1 through bolts and are respectively positioned at the box opening and the box bottom of the box body 1, the slide rail 21 is provided with a slide groove 211, and the bottom wall of the slide groove 211 is provided with positioning grooves 212 which are arranged along the extending direction of the slide groove 211; the back surfaces of the two ends of the clamping strip 22 are integrally formed or connected with sliding blocks 222 through bolts, and the two sliding blocks 222 are respectively matched in the two sliding grooves 211; the card strip 22 has a card slot 221 on the front surface thereof, and the card strip 22 has a through hole 2221 penetrating the card strip 22 and the slider 222. The positioning pin assembly 4 comprises a pin rod 41 and an elastic member 42, the pin rod 41 is movably fitted in the through hole 2221, a first end 411 of the pin rod 41 corresponds to the slot 221, and a second end 412 corresponds to the positioning slot 212; the elastic member 42 is disposed between the pin rod 41 and the slider 222, and naturally pushes the pin rod 41 to move away from the positioning slot 212, so that a first end of the pin rod 41 passes through the clip strip 22 and enters the clip slot 221, and a second end of the pin rod is separated from the positioning slot 212. The two sides of the mounting plate 3 can be clamped into the two corresponding clamping grooves 221 of the two sets of clamping strip structures 2, and when the mounting plate 3 passes through the pin rod 41, the pin rod 41 can be extruded to move towards the positioning groove 212, so that the second end of the pin rod 41 is clamped into the positioning groove 212.
In this embodiment, the plurality of card strips 22 in each group of card strip structures 2 may be arranged in parallel, the card strips 22 in two groups of card strip structures 2 are arranged in a one-to-one correspondence, and two corresponding card strips 22 form a group of card strip groups for the two side edges of the same mounting plate 3 to be clamped in. When the electrical component is specifically installed, the mounting plate 3 is drawn out from the clamping groove 221 of the clamping strip 22, then the corresponding electrical component is fixed on the mounting plate 3 in a bolt connection or clamping manner, then the mounting plate 3 is clamped into the clamping groove 221 of the clamping strip 22, and the installation of the corresponding electrical component is completed. In the process of inserting the mounting plate 3 into the slot 221, when the insertion depth of the mounting plate 3 relative to the box body 1 is shallow, the side edge of the mounting plate 3 is not in contact with the pin rod 41, so that the second end of the pin rod 41 is in a separated state from the positioning slot 212, and the clamping strip 22 can slide left and right on the slide rail 21 through the slide block 222 in the state, so as to adjust the proper distance between the mounting plates 3 according to the size of the electrical component; after the distance adjustment is completed, the mounting plate 3 is continuously inserted into the bottom of the box body 1 along the clamping groove 221, so that the side edge of the mounting plate 3 is in contact with the pin rod 41, the pin rod 41 is extruded at the same time, the pin rod 41 moves towards the positioning groove 212, the second end of the pin rod 41 is inserted into the positioning groove 212, the positioning of the sliding block 222 and the clamping strip 22 is realized, the problem that the clamping strip 22 accidentally slides on the sliding rail 21 is avoided, and the stability of the installation of the electrical appliance element is ensured. When the mounting plate 3 is pulled out of the slot 221, the mounting plate 3 presses the pin rod 41 to release, the second end of the pin rod 41 is separated from the positioning slot 212, and the slider 222 can slide freely. Under this structure, showing and promoted operating personnel and with electrical components in box 1 the convenience of packing into and fixing, still promoted the flexibility that electrical components packed into simultaneously, can effectively utilize 11 inner spaces of box.
The first end of the slot 221 corresponds to the opening of the chassis and is provided with an opening 2211, the second end corresponds to the bottom of the chassis and is a closed end 2212, and the positioning pin assembly 4 is located at the position of the slot 221 corresponding to the closed end 2212. The open end 2211 is convenient for the insertion of the mounting plate 3, and the closed end 2212 can limit the insertion depth of the mounting plate 3 so as to improve the stability of the insertion of the mounting plate 3; the positioning pin assembly 4 is arranged at the closed end 2212, so that the inserting depth of the mounting plate 3 can be increased in the process of inserting and adjusting an electrical element, and the situation that the mounting plate 3 extrudes the pin rod 41 too early to cause the position of the clamping strip 22 to be difficult to adjust is avoided.
The front door panel 16 of the box body 1 is provided with a pressing strip 161, and when the front door panel 16 covers the opening of the box body 1, the pressing strip 161 is pressed against the opening end 2211 of the clamping groove 221. With the structure, when the front door plate 16 is in a closed state, the mounting plate 3 can be positioned, so that the problem that the mounting plate 3 shakes forwards and backwards is avoided; when the front door panel 16 is opened, the mounting plate 3 can be directly drawn out from the clamping groove 221, and the operation is convenient.
An outer step 22211 is formed on the outer wall of the pin rod 41, a threaded sleeve 5 is screwed in the through hole 2221, the elastic member 42 is a spring, the spring is sleeved on the pin rod 41, a first end of the spring abuts against the outer step 22211 of the pin rod 41, and a second end of the spring abuts against the threaded sleeve connected in the through hole 2221. When the first end of the pin rod 41 is completely pressed into the through hole 2221, the second end of the pin rod 41 enters the positioning groove 212, and the spring is in a compressed state, so that after the mounting plate 3 is separated from the pin rod 41, the spring can push the pin rod 41 to leave the positioning groove 212, so that the first end of the pin rod enters the clamping groove, and the outer step of the pin rod abuts against the inner step of the through hole.
The first end 411 of the pin rod 41 has an inclined structure, and the second end 412 has an isosceles trapezoid structure. The first end of the pin rod 41 is obliquely arranged, so that the pin rod can be conveniently matched with the side edge of the mounting plate 3, and the phenomenon of clamping when the mounting plate 3 extrudes the pin rod 41 is avoided; the second end of the pin rod 41 is of an isosceles trapezoid structure, so that the area of the second end of the pin rod 41 can be reduced, the pin rod can be conveniently clamped into the positioning groove 212, and the positioning groove 212 is also of an isosceles trapezoid structure.
The sliding groove 211 and the sliding block 222 are matched in a T-shaped structure. This structure can improve the stability of the fitting of the clip strip 22 on the slide rail 21.
