[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] Depend on Figure 1-7 The utility model comprises a base 1, a cabinet body 2 and a cabinet door 3. A storage groove is provided on the top of the base 1. The bottom of the cabinet body 2 is located in the storage groove on the base 1. The cabinet door 3 is located at the opening on the front of the cabinet body 2. Two hinges 4 are fixedly installed between one end of the cabinet door 3 and the cabinet body 2. A groove is provided at the bottom of the storage groove. A hydraulic rod 6 is fixedly installed in the groove. The telescopic end of the hydraulic rod 6 is fixedly connected to the bottom of the cabinet body 2. A vertical through hole 7 is provided inside the cabinet door 3 and is connected to the cabinet body 2. A limit rod 9 is movably inserted in the through hole 7. The bottom of the cabinet body 2 is provided with a through hole 7 that is connected to the cabinet body 2. A through opening 11 corresponds to the position of the through hole 7, and a limiting groove 13 corresponding to the position of the through hole 7 is opened at the top of the opening of the cabinet body 2. A top rod 12 that penetrates and is inserted into the through opening 11 is fixedly installed at the bottom of the storage groove. When the bottom of the cabinet body 2 contacts the storage groove, the top end of the top rod 12 extends into the through hole 7 and pushes the limiting rod 9 to move up so that its top end is inserted into the limiting groove 13. Through the engagement of the limiting rod 9 and the limiting groove 13, and the insertion of the top rod 12 into the through opening 11 on the cabinet body 2 and the through hole 7 on the cabinet door 3, the cabinet door 3 can be stably closed at the opening of the cabinet body 2.
[0022] At the same time, an inner groove 8 is opened at the middle position of the through hole 7, and a limit block 10 is fixedly installed at the middle position of the limit rod 9. The limit block 10 is located in the inner groove 8 and can move up and down therein. The limit block 10 can prevent the limit rod 9 from detaching from the through hole 7, and the limit block 10 can limit the movement range of the limit rod 9 in the through hole 7.
[0023] In addition, the height of the limit rod 9 is the same as the height of the cabinet door 3. When the two ends of the limit rod 9 are flush with the top and bottom of the cabinet door 3, the limit block 10 on the limit rod 9 is located in the lower half of the inner groove 8. When the limit block 10 on the limit rod 9 is located in the upper half of the inner groove 8, the top end of the limit rod 9 extends out of the through hole 7 and is inserted into the limit groove 13. By controlling the hydraulic rod 6, the cabinet body 2 can move up and down in the storage groove on the base 1. When the bottom of the cabinet body 2 contacts the storage groove, the top end of the push rod 12 can extend into the through hole 7 on the cabinet door 3. The push rod 12 lifts the limit rod 9 upward so that its top end is inserted into the limit groove 13, thereby closing the cabinet door 3 at the opening of the cabinet body 2.
[0024] Furthermore, the inner wall of the storage groove fits with the exterior of the cabinet 2 , so that the cabinet 2 can be stably placed in the storage groove on the base 1 .
[0025] In addition, connecting grooves 14 are provided on both sides of the bottom of the storage groove, and connecting plates 15 are fixedly installed at both ends of the bottom of the cabinet 2. The two connecting plates 15 are movably inserted into the corresponding connecting grooves 14 respectively. Through the cooperation between the connecting plates 15 and the connecting grooves 14, the cabinet 2 can be more stable when moving up and down.
[0026] In addition, a handle 5 is fixedly installed on the front of the cabinet door 3, and the handle 5 is used to pull the cabinet door 3 to flip over the opening of the cabinet body 2.
