DETAILED DESCRIPTION

[0025] The technical scheme of the utility model will be further described in detail in combination with specific embodiment, and the part that is not recorded and disclosed in each embodiment of the utility model below should be understood as the prior art that the person skilled in the art knows or should know.

[0026] Example 1

[0027] As Figure 1 , Figure 2As shown, a high-voltage switch cabinet handcart room slide rail includes two slide rail units respectively mounted on the two side walls of the switch cabinet, and the slide rail units are a certain distance apart to ensure that the handcart smoothly enters the handcart room. The slide rail unit includes a connecting plate 1 parallel to and fixedly connected to the side wall of the switch cabinet. The connecting plate 1 is a rectangular plate structure, and the length of the connecting plate 1 is equal to or slightly smaller than the depth of the handcart room of the switch cabinet. The connecting plate 1 is connected to the side wall of the switch cabinet by bolts. The same side of the connecting plate 1 is vertically provided with an upper limiting plate 2 and a track plate 3, and the upper limiting plate 2 and the track plate 3 are parallel to each other, so that the connecting plate 1, the upper limiting plate 2 and the track plate 3 form a roller cavity 5 for the roller to slide. When the handcart enters or is pulled out of the handcart room, the roller of the handcart is located in the roller cavity 5 and moves along the length direction of the track plate 3. The upper limiting plate 2 is arranged at the position close to the top end of the connecting plate 1 and is integrally connected with the connecting plate 1. The arrangement of the upper limiting plate 2 prevents the handcart from moving up and down during pulling out or loading. The track plate 3 is arranged at the middle position of the connecting plate 1 and is integrally connected with the connecting plate 1. The width of the upper limiting plate 2 is smaller than the width of the track plate 3, and the lengths of the upper limiting plate 2 and the track plate 3 are the same as the length of the connecting plate 1.

[0028] The end of the track plate 3 away from the connecting plate 1 is vertically provided with a side plate 6, and the side plate 6 is integrally connected with the track plate 3. The side plate 6 extends away from the side of the track plate 3 facing away from the upper limiting plate 2, so that the side plate 6, the track plate 3 and the connecting plate 1 form a guide plate chamber 10 with an open bottom. A guide plate 11 is movably arranged in the guide plate chamber 10, and the width of the guide plate 11 is smaller than the width of the guide plate chamber 10. When the guide plate 11 is pulled out of the guide plate chamber 10, the end of the guide plate 11 can be lapped on the end of the track plate 3. When the high-voltage switch cabinet is working normally, the guide plate 11 is located in the guide plate chamber 10, and the guide plate 11 is parallel to the track plate 3. When pulling out or loading the handcart, the guide plate 11 is pulled out of the guide plate chamber 10, and one end of the guide plate 11 is abutted against the lower surface of the end of the track plate 3 close to the outside of the handcart room, so as to realize the lapping of the guide plate 11 and the track plate 3. The handcart enters or exits the handcart room along the guide plate 11, which plays a labor-saving role and facilitates the pulling out and loading of the handcart.

[0029] The guide plate 11 is arranged in the guide plate chamber 10 and is placed on the cross ribs 9 when the guide plate 11 is not used. The two ends of the cross rib 9 are fixedly connected with the connecting plate 1 and the side plate 6. In the embodiment, three circular holes are formed in the side plate 6 away from the side wall of the track plate 3, and the circular holes are uniformly distributed along the length direction of the track plate 3. The distance between the circular holes is equal. A circular hole is arranged on the connecting plate 1, and the circular hole on the connecting plate 1 corresponds to the circular holes on the side plate 6 one by one. The diameter of the circular hole on the connecting plate 1 is equal to the diameter of the circular hole on the side plate 6. The length of the cross rib 9 is greater than the width of the inner side wall of the guide plate chamber 10. The cross rib 9 passes through the circular hole on the connecting plate 1 and then passes through the circular hole on the side plate 6, so that the cross rib 9 is clamped on the two circular holes. The diameter of the cross rib 9 is not greater than the inner diameter of the circular hole, so that the cross rib 9 can smoothly pass through the circular hole. At the same time, the cross rib 9 can rotate in the guide plate chamber 10. When the guide plate 11 is pulled out or turned in, the friction between the guide plate 11 and the cross rib 9 is reduced, and then the guide plate 11 is pulled out or turned in more labor-saving.

[0030] The side limiting part 4 is vertically arranged at one end of the track plate 3 away from the connecting plate 1. The side limiting part 4 is integrally connected with one end of the track plate 3, and extends towards the upper limiting plate 2, so as to prevent the wheels of the handcart from being deviated left and right during movement. In the embodiment, the length of the side limiting part 4 is equal to the length of the track plate 3. The height to which the side limiting part 4 extends is slightly higher than the upper side of the track plate 3, so that there is a certain distance between the top end of the side limiting part 4 and the lower surface of the upper limiting plate 2, thereby ensuring that the wheels can smoothly enter the wheel cavity 5.

[0031] The above is the basic embodiment of the utility model, which can be further improved, optimized and limited on the basis of the above, so as to obtain the following embodiments:
