[0030] [First Embodiment]

[0031] As Figures 1-4 shown is an internal mounting rack of a switch cabinet provided by the first embodiment of the present utility model. As Figure 1 shown, it includes two side carriers 1. A plurality of guide rails 2 are arranged between the two side carriers 1. The guide rails 2 and the carriers 1 are connected by a connecting structure 3. By setting the connecting structure, the convenient loading and unloading of the guide rails from the carriers can be realized, so as to solve the problems of inconvenient loading and unloading and inflexible use brought by the connection method in the prior art that each guide rail needs to be fixed to the switch cabinet separately by screws or welding.

[0032] As Figures 2-3As shown in the figure, the connection structure 3 in this embodiment includes a connection block 31 fixed on the guide rail 2 and a connection groove 32 opened on the carrier 1. The connection block 31 and the connection groove 32 are correspondingly inserted and matched. By inserting the connection block 31 into the corresponding connection groove 32, several guide rails can be installed on the carrier, so as to solve the problems of inconvenient loading and unloading and inflexible use caused by the connection method in the prior art that each guide rail needs to be fixed to the switch cabinet separately by screws or welding.

[0033] As Figure 3 shown, relief grooves 33 are respectively opened on the inner walls on both sides of the connection groove 32. A limiting block 34 is slidably inserted into the relief groove 33. Limiting grooves 35 are respectively opened on both sides of the connection block 31. The limiting block 34 can enter the inside of the limiting groove 35 and be limited in cooperation with it. Through the limiting cooperation between the limiting block 34 and the limiting groove 35, the connection between the carrier and the guide rail can be made more stable; at the same time, sliding rods 36 are respectively slidably inserted into both sides of the connection groove 32. One end of the sliding rod 36 is fixedly connected to the limiting block 34, and the other end of the sliding rod 36 is fixedly connected to a pull ring 38. Therefore, the sliding rod 36 can be slid by the pull ring 38, and then the position of the limiting block 34 can be operated to make the disassembly operation more convenient; further, an elastic member 37 is sleeved on the sliding rod 36. One end of the elastic member 37 is fixed on the inner wall of the relief groove 33, and the other end of the elastic member 37 is fixed on the limiting block 34. The elastic member 37 in this embodiment is selected as a spring. In this embodiment, one side of the limiting block 34 is set as an inclined surface. During the process of inserting the connection block 31 into the connection groove 32, the two limiting blocks 34 will be pushed to slide into the two relief grooves 33 and the elastic member 37 will be compressed and contracted. Therefore, when the connection block is completely stuck into the connection groove, the limiting block contacts the limiting groove, and the limiting block will be stuck into the limiting groove under the action of the elastic return force of the elastic member, further improving the convenience of the operation and the stability of the connection block being limited in the connection groove.

[0034] As Figure 4 shown, a plurality of clamping structures 4 are arranged on the guide rail 2 in this embodiment. By arranging the clamping structures, clamping and fixing of electrical components with different sizes can be realized, the applicable range can be increased, and the application rate can be improved.

[0035] Its specific structure is as follows: the clamping structure 4 includes a slide groove 41 provided on the guide rail 2, and two sliders 42 are slidably connected in the slide groove 41. The components of the electrical components are placed on the guide rail, and the two sliders are slid to clamp the components, so that the components of the electrical components can be easily installed and removed; a bidirectional screw 43 is rotatably connected in the slide groove 41, and the two sections of threads on the bidirectional screw 43 are in opposite directions. The bidirectional screw 43 is threadedly connected to the two sliders 42 through two sections of threads respectively. Since the slider slides in the slide groove, the rotation of the bidirectional screw can drive the two sliders to slide synchronously in the opposite direction, making the clamping operation more stable; a first bevel gear 44 is fixedly connected to the bidirectional screw 43, and a turning handle 47 is rotatably connected to the top of the guide rail 2. One end of the turning handle 47 extending into the slide groove 41 is connected to the second The bevel gear 45 is fixedly connected, and the first bevel gear 44 is meshed with the second bevel gear 45 accordingly. Manually turning the handle will drive the second bevel gear to rotate, and then drive the first bevel gear to rotate, and further drive the bidirectional screw to rotate, so that the two sliders 42 move toward or away from each other, thereby realizing the clamping or releasing operation of the electrical component; further, a fixing plate 46 is fixed at the position corresponding to the slide groove 41 at the bottom of the guide rail 2, and the components of the electrical component are placed on the fixing plate through the fixing plate 46, and the fixing plate can support it to make its position more stable; as a further preference, a limit device can also be provided on the handle 47 to realize the limiting effect of the current position when the handle 47 is rotated to the current position, so as to avoid the possibility of unexpected loosening during the clamping process.

[0036] The specific working process of this embodiment is:

[0037] When installing the guide rails, two carrier frames 1 are installed in the switch cabinet, and then the connecting blocks 31 are inserted into the corresponding connecting grooves 32, and a plurality of guide rails 2 can be installed on the carrier frames 1, thereby avoiding the situation that each guide rail 2 needs to be fixed to the switch cabinet by screws or welding separately, which makes the installation operation more troublesome, resulting in inconvenient installation and disassembly, and inflexible use.

[0038] The two limit blocks 34 are slid into the corresponding limit grooves 35, so that the connection between the carrier 1 and the guide rail 2 is more stable. The slide rod 36 can be slid by the pull ring 38 to operate the position of the limit block 34, making the operation more convenient. One side of the limit block 34 is a slope. During the insertion of the connecting block 31 into the connecting groove 32, the two limit blocks 34 will be pushed to slide into the two make way grooves 33 and squeeze the elastic member 37 to shrink. Therefore, when the connecting block 31 is completely inserted into the connecting groove 32, the limit block 34 contacts the limit groove 35, and the limit block 34 is inserted into the limit groove 35 under the action of the rebound elastic force of the elastic member 37, further improving the convenience of operation.

[0039] Place the components of the electrical component on the guide rail 2. Slide the two sliders 42 to clamp the components, which facilitates the installation and disassembly of the components of the electrical component. Since the sliders 42 are limitedly slid in the chute 41, rotating the bidirectional screw 43 can drive the two sliders 42 to slide synchronously and reversely, making the clamping operation more stable. When the staff manually rotates the handle 47, it will drive the second bevel gear 45 to rotate, and then drive the first bevel gear 44 to rotate. Further, it can drive the bidirectional screw 43 to rotate, so that the two sliders 42 move towards or away from each other, thereby realizing the clamping or releasing operation of the electrical component, making the operation more convenient. Place the components of the electrical component on the fixing plate 46, and the fixing plate 46 can support it to make its position more stable.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention. In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
