Description

Technical Field

[0001] This utility model belongs to the field of mobile catering vehicle technology, and in particular relates to a mobile catering vehicle for mining. Background Technology

[0002] For example, a mobile dining vehicle for underground use, disclosed in Chinese invention patent CN117481459A, has the following structural design: a dining area is located on one side of the vehicle's interior; an insulated box is located on the side of the vehicle's interior away from the dining area; a blocking component is installed inside the insulated box; a storage cabinet is located on the opposite side of the insulated box; a mobile dining box is positioned between the insulated box and the storage cabinet; a second wheel is installed at the bottom of the mobile dining box; a first shelf is installed inside the mobile dining box; and an anti-tilt component is installed between the first shelf and the mobile dining box. A pushing component is installed on the side of the shelf away from the insulated box. A sliding component is slidably connected to the bottom of the mobile meal box. A mobile cart for transporting the mobile meal box is installed on the side of the sliding component away from the meal cart body. Clamping components for fixing the mobile meal box are installed on both sides of the first slide rail. By setting up the mobile meal box, it is possible to avoid returning the entire meal cart to the surface to refill food when food is insufficient, which greatly improves the efficiency of meal transportation and ensures the smooth operation of mine operations. Therefore, it can be seen that the existing mobile meal cart basically meets people's needs, but the following problems still exist.

[0003] The dining area is located on one side of the interior of the dining car, with tables and benches for operators to sit and eat. However, due to the long benches and the long table in front of them, when workers are eating in the dining area, if the worker in the middle of the bench finishes eating and needs to leave, the workers on the sides of the bench may need to get up and make way for the worker in the middle, which may affect their dining. Therefore, we propose a mobile dining car for mining. Utility Model Content

[0004] This utility model provides a mobile dining cart for mining. After the support plate rotates on one side of the support frame, the seat moves to the surface of the support plate. The operator sits on the seat, which is supported by the support plate. The dining table is used to place the lunch box. When the operator is eating, there is no need for the workers on both sides to give way to the workers in the middle, thus improving the operator's dining comfort.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile catering cart for mining, comprising a cart body, a dining table, and a support frame. The support frame is threadedly installed inside the cart body, and the dining table is threadedly installed at the end of the support frame. Each surface of the support frame has a storage groove, and a support plate is inserted into the middle of each storage groove. The support plate and the storage groove are rotatably connected. Each end of the support plate is slidably connected to a second rotating shaft, and a rotating block is sleeved on the surface of each second rotating shaft. Each end of the rotating block is fixed with a seat plate inserted into the dining table. A second support plate is fixed on the inner wall of the cart body near the support plate, and a limit block is fixed on the outer wall of each second support plate. A reinforcing frame is fixed inside each second support plate.

[0006] Furthermore, each of the dining tables has a clearance groove in the middle, and a carrying plate is inserted into the middle of each clearance groove, with the carrying plate and the clearance groove being elastically connected.

[0007] Furthermore, the inner wall of the clearance groove is fixed with several sets of spring grooves, and a second spring and a push rod are respectively provided inside the spring groove. The two ends of the second spring abut against the inner wall of the spring groove and the surface of the push rod, and the ends of the push rod are all fixed to the loading plate.

[0008] Furthermore, the clearance slots are all configured as rectangular grooves, and the carrying plates are all configured as rectangular blocks, with the rectangular grooves of the clearance slots matching the rectangular blocks of the carrying plates.

[0009] Furthermore, each of the support frames is fitted with a collar, and each collar is fixed with a slider on the side near the support frame surface. Each slider is fitted with a groove opened in the support frame, and each groove is fixed with a sliding rod that passes through the slider. Each sliding rod is wound with a first spring that abuts against the slider surface and the inner wall of the groove.

[0010] Furthermore, a pressing plate and a first support plate that are in contact with the support plate are respectively fixed on the surface of the collar.

[0011] Furthermore, the support plate has a first rotating shaft running through it on the side away from the seat plate, and both ends of the first rotating shaft are fixed to the inner wall of the storage groove.

[0012] Furthermore, traction blocks are symmetrically fixed at both ends of the second rotating shaft, and traction grooves are provided on the surface of each traction block within the support plate.

[0013] Furthermore, the second rotating shaft is always cylindrical, and each rotating block has a waist-shaped hole in the middle, and the waist-shaped hole in the middle of the rotating block matches the cylindrical shape of the second rotating shaft.

[0014] The beneficial effects of this utility model are:

[0015] 1. This mobile dining cart for mining is equipped with a support plate, a seat plate, a second rotating shaft, and a first rotating shaft. When the operator pulls the seat plate, the seat plate raises the second rotating shaft, which in turn pulls the support plate to move. The support plate rotates through the first rotating shaft, causing it to move out of the storage slot. The seat plate also drives a rotating block to rotate on the surface of the second rotating shaft, causing the seat plate and the support plate to fit together, thus providing support for the seat plate. The operator sits on the seat plate and then places the meal box on the table. When the operator is eating, the workers on both sides no longer need to give way to the workers in the middle, and the footprint of the dining table and benches is reduced, improving the operator's dining comfort.

[0016] 2. This mobile catering cart for mining is equipped with a loading plate, a push rod, a spring groove, and a second spring. After the operator places the food container on the surface of the loading plate, the loading plate pushes the push rod to slide in the spring groove, causing the loading plate to slide in the clearance groove, moving the loading plate downwards. There is a height difference between the loading plate and the opening of the clearance groove, which prevents the food container or tableware from falling off when workers place it on the surface of the loading plate, thus improving the usability for the operator.

[0028] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings. Example:

[0029] Please see Figure 1 - Figure 9A mobile catering cart for mining includes a cart body 1, a dining table 2, and a support frame 3. The support frame 3 is threadedly installed inside the cart body 1, and the dining table 2 is threadedly installed at the end of the support frame 3. Each surface of the support frame 3 has a storage slot 9, and a support plate 24 is inserted into the center of each storage slot 9. The support plate 24 and the storage slot 9 are rotatably connected. A first rotating shaft 15 passes through the side of the support plate 24 away from the seat plate 6, and both ends of the first rotating shaft 15 are welded to the inner wall of the storage slot 9. A second rotating shaft 18 is slidably connected to the end of each support plate 24. Traction blocks 25 are symmetrically welded to both ends of the second rotating shaft 18. All surfaces of the food cart 1 are fitted with traction grooves 19 formed within the support plate 24, and all surfaces of the second rotating shaft 18 are fitted with rotating blocks 8. Each rotating block 8 has a seat plate 6 welded to its end, which is inserted into the dining table 2. A second support plate 17 is welded to the inner wall of the food cart body 1 near the support plate 24, and a limit block 4 is welded to the outer wall of the second support plate 17. A reinforcing frame 7 is welded inside the second support plate 17. When the operator uses the cart, they place the food container and tableware on the dining table 2, and then pull the seat plate 6. The seat plate 6 moves the second rotating shaft 18 via the rotating blocks 8, and the second rotating shaft 18 moves the traction grooves 19 via the traction blocks 25. The traction groove 19 drives the support plate 24 to move. During this movement, the support plate 24 rotates through a circular through-hole on one side of the first rotating shaft 15, causing it to rotate within the receiving groove 9. The support plate 24 then rotates out of the receiving groove 9 and moves onto the surface of the second support plate 17, where it comes into contact with the second support plate 17. As the support plate 24 rotates through the first rotating shaft 15, the operator pulls the seat plate 6. The seat plate 6 causes the oblong hole in the center of the rotating block 8 to rotate on the surface of the second rotating shaft 18, causing the seat plate 6 and the support plate 24 to move together. Separate the seat plate 6 to avoid the support plate 24. Then, the operator pushes the seat plate 6, which causes the waist-shaped hole in the middle of the rotating block 8 to rotate on the surface of the second rotating shaft 18, making the seat plate 6 parallel to the support plate 24. Then, the operator pushes the seat plate 6 again, which causes the waist-shaped hole in the middle of the second rotating shaft 18 to slide on the surface of the second rotating shaft 18, making the seat plate 6 and the support plate 24 fit together. Then, the operator sits on the seat plate 6. When the operator is eating, the workers on both sides no longer need to give way to the workers in the middle, and the area occupied by the dining table and bench is reduced, improving the operator's dining comfort.

[0030] When the operator needs to adjust the position of the seat plate 6, the operator pulls the seat plate 6, the seat plate 6 drives the rotating block 8 to move, the rotating block 8 drives the second rotating shaft 18 to move, and the second rotating shaft 18 drives the traction block 25 to slide in the traction groove 19, so that the seat plate 6 can slide on the surface of the support plate 24, making it convenient for the operator to adjust the position of the seat plate 6 according to their own situation, thus improving the operator's usability.

[0031] In other embodiments, a clearance groove 26 is provided in the middle of the dining table 2, and a carrying plate 20 is inserted into the middle of the clearance groove 26. The carrying plate 20 is elastically connected to the clearance groove 26. Several sets of spring grooves 22 are welded to the inner wall of the clearance groove 26. A second spring 23 and a push rod 21 are respectively provided inside the spring groove 22. The two ends of the second spring 23 abut against the inner wall of the spring groove 22 and the surface of the push rod 21, respectively. The ends of the push rod 21 are welded to the carrying plate 20. When the operator places the lunch box and tableware on the surface of the carrying plate 20, the weight of the lunch box and tableware is greater than the elastic force of the second spring 23. The carrying plate 20 pushes the push rod 21 to move. The push rod 21 slides in the spring groove 22. When the push rod 21 slides in the spring groove 22, the push rod 21 squeezes... The second spring 23 is compressed, causing it to elastically deform. After the second spring 23 elastically deforms, it avoids the push rod 21, and the carrying plate 20 moves downward in the avoidance groove 26. A height difference is created between the carrying plate 20 and the avoidance groove 26, preventing workers from placing lunch boxes and tableware on the surface of the carrying plate 20 and causing them to fall, thus improving the usability for the operator. When the operator removes the lunch box and tableware from the surface of the carrying plate 20, the weight of the carrying plate 20 is less than the elastic force of the second spring 23, and the second spring 23 recovers its elastic deformation. The second spring 23 pushes the push rod 21 to move, and the push rod 21 moves the carrying plate 20, causing it to slide upward in the avoidance groove 26. The height difference between the carrying plate 20 and the avoidance groove 26 is no longer present.

[0032] In other embodiments, the clearance grooves 26 are all configured as rectangular grooves, and the carrying plates 20 are all configured as rectangular blocks. The rectangular grooves of the clearance grooves 26 and the rectangular blocks of the carrying plates 20 are matched with each other. By matching the rectangular grooves of the clearance grooves 26 and the rectangular blocks of the carrying plates 20, the outer walls of the carrying plates 20 are in close contact with the inside of the clearance grooves 26, preventing the carrying plates 20 from shaking in the clearance grooves 26 when sliding, and increasing the stability of the carrying plates 20 when sliding.

[0033] In other embodiments, a collar 5 is fitted onto the surface of the support frame 3. A slider 14 is welded to the side of the collar 5 closest to the surface of the support frame 3. A groove 12 is fitted onto the surface of the slider 14 and is formed within the support frame 3. A sliding rod 16 is welded into the groove 12 and passes through the slider 14. A first spring 11 is wound around the surface of the sliding rod 16 and abuts against the surface of the slider 14 and the inner wall of the groove 12. When the operator needs to remove the support plate 24 from the storage slot 9, the operator first pulls the collar 5 to move it. The collar 5 slides on the surface of the support frame 3. When the collar 5 moves, the slider 14 inside the collar 5 slides within the groove 12. When the slider 14 slides within the groove 12, the circular opening in the middle of the slider 14... The hole rotates on the surface of the cylindrical slide bar 16. The slide bar 16 pulls the movement trajectory of the slider 14, increasing the stability of the slider 14 sliding in the groove 12. When the slider 14 slides in the groove 12, the slider 14 squeezes the first spring 11, causing the first spring 11 to undergo elastic deformation. After the first spring 11 undergoes elastic deformation, it avoids the slider 14, causing the slider 14 to drive the collar 5 to slide on the surface of the support frame 3. The collar 5 moves away from the surface of the storage groove 9. Then the operator pulls the support plate 24. The support plate 24 is rotated on the surface of the first rotating shaft 15 through the circular through hole on one side, causing the support plate 24 to move out of the storage groove 9.

[0034] When the operator retracts the support plate 24 into the storage slot 9, and needs to fix the support plate 24 in the storage slot 9, the operator moves the support plate 24 into the storage slot 9, and then releases the collar 5. After the collar 5 stops pressing the first spring 11 through the slider 14, the first spring 11 recovers its elastic deformation and pushes the slider 14 to move. The slider 14 drives the collar 5 to slide on the surface of the support frame 3, moving the collar 5 to the front end of the storage slot 9, thereby restricting the support plate 24 stored in the storage slot 9 and preventing the support plate 24 from being moved out of the storage slot 9. This makes it convenient for the operator to store the support plate 24 after it is no longer needed.

[0035] In other embodiments, a pressing plate 13 and a first support plate 10 that fits against the support plate 24 are welded to the surface of the collar 5. When the operator pulls the collar 5, the operator presses the pressing plate 13 with his foot, causing the pressing plate 13 to pull the collar 5, which facilitates the operator's pulling of the collar 5. The first support plate 10 is fixed on the other side of the collar 5, so that after the support plate 24 rotates out of the storage groove 9 through the first rotating shaft 15, the first support plate 10 pushes the support plate 24, increasing the stability of the support plate 24 in use.

[0036] In other embodiments, the second rotating shaft 18 is always cylindrical, and the rotating block 8 is always provided with an oblong hole in the middle. The oblong hole in the middle of the rotating block 8 matches the cylindrical shape of the second rotating shaft 18. When the operator pulls the seat plate 6 to move, the seat plate 6 drives the rotating block 8 to move. When the rotating block 8 moves, the oblong hole in the middle of the rotating block 8 slides on the cylindrical surface of the second rotating shaft 18, so that the oblong hole in the middle of the rotating block 8 avoids the second rotating shaft 18, and the oblong hole in the middle of the rotating block 8 can rotate the surface of the second rotating shaft 18.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
