[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-Figure 3 As shown, this embodiment provides a corner wheel for moving a heavy-duty energy storage box, including a load-bearing frame 1, an inner wall of the load-bearing frame 1 is rotatably connected to a roller 2, the top of the load-bearing frame 1 is rotatably connected to a rotating shaft 3, the circumferential outer wall of the rotating shaft 3 is located above the load-bearing frame 1 and is fixedly connected to a rotating plate 4, an angle piece 5 is provided on the load-bearing frame 1, and the angle piece 5 is fixedly installed at the bottom of the energy storage box, the load-bearing frame 1 is clamped and fixed with the angle piece 5 through the rotating plate 4, and then the load-bearing frame 1 and the roller 2 are installed at the bottom of the energy storage box, a pin groove is provided on the side wall of the rotating shaft 3 located in the load-bearing frame 1, and a fixing screw 6 is slidably connected to the inner wall of the pin groove, and the fixing screw 6 is threadedly connected to both sides of the load-bearing frame 1, and the fixing screw 6 limits the rotation of the rotating shaft 3 and the rotating plate 4 to prevent the clamping fixation of the rotating plate 4 and the angle piece 5 from being released.

[0027] At the same time, an auxiliary mechanism 7 is provided on the load-bearing frame 1. The auxiliary mechanism 7 is used to drive the rotating shaft 3 to rotate, and after the rotating shaft 3 is rotated, the rotating shaft 3 is pulled in the direction away from the angle piece 5, so that the rotating plate 4 and the angle piece 5 are squeezed and matched. After the rotating plate 4 is rotated to clamp and fix the angle piece 5 and the load-bearing frame 1, the rotating plate 4 is used to press the angle piece 5 in the direction close to the load-bearing frame 1, thereby increasing the friction between the angle piece 5 and the load-bearing frame 1 and improving the stability of the roller 2 installed on the energy storage box.

[0028] In order to realize the clamping and fixing of the corner piece 5 and the load-bearing frame 1 by rotating the rotating plate 4, the structure of the corner piece 5 is detailed as follows. Figure 4The corner piece 5 includes a positioning block 51, an embedded groove 52 is provided at the bottom of the positioning block 51, and a clamping groove 53 is provided on the inner wall of the embedded groove 52. A sleeve frame is fixedly connected to the upper surface of the load-bearing frame 1, and the embedded groove 52 is slidably sleeved on the outer side of the sleeve frame. The rotating plate 4 is squeezed and matched with the bottom surface in the clamping groove 53. By increasing the pressure of the rotating plate 4 on the bottom surface of the clamping groove 53, the friction between the rotating plate 4 and the positioning block 51 is increased, so that the rotating plate 4 will not move easily inside the clamping groove 53, so that the clamping connection between the load-bearing frame 1 and the positioning block 51 is more stable. The positioning block 51 is squeezed and matched with the upper surface of the load-bearing frame 1. Similarly, the friction between the positioning block 51 and the load-bearing frame 1 is increased. When the corner wheel is impacted by the outside, the relative position of the load-bearing frame 1 and the positioning block 51 will not change easily. The change reduces the possibility of damage to the swivel plate 4 and the rotating shaft 3 and improves the impact resistance of the angle wheel. The sleeve frame is sleeved on the outside of the rotating shaft 3, and the sleeve frame is located below the swivel plate 4. After the swivel plate 4 is rotated 90 degrees with the rotating shaft 3 as the rotation center, the swivel plate 4 and the sleeve frame overlap each other up and down. When installing the load-bearing frame 1, the swivel plate 4 and the sleeve frame that overlap each other up and down are inserted into the embedded groove 52 until the upper surface of the load-bearing frame 1 contacts the lower surface of the positioning block 51. The rotating shaft 3 is rotated 90 degrees, and the swivel plate 4 can be rotated into the inside of the card slot 53. At this time, the swivel plate 4 and the card slot 53 cooperate to limit the vertical separation of the load-bearing frame 1 and the positioning block 51, and the sleeve frame and the embedded groove 52 cooperate to limit the horizontal separation of the load-bearing frame 1 and the positioning block 51, thereby realizing the card connection and fixation of the load-bearing frame 1 and the positioning block 51.

[0029] In order to facilitate the rotation of the rotating shaft 3 and the rotating plate 4, the following is a detailed description of the partial structure of the auxiliary mechanism 7. Figure 5 The auxiliary mechanism 7 includes an extension plate 71 rotatably connected to the outer wall of the circumference of the rotating shaft 3. A gear 72 is fixedly connected to the outer wall of the rotating shaft 3 below the extension plate 71. A rack 74 is meshed and connected to one side of the gear 72. The gear 72 can be driven to rotate by moving the rack 74 along a fixed path. The rack 74 is slidably connected to the bottom of the extension plate 71. A plurality of guide rods 73 are fixedly connected to the top surface of the load-bearing frame 1. The lower end of the guide rod 73 passes through the side wall of the extension plate 71. The side wall of the rack 74 is provided with a movable The groove and the lower surface of the extension plate 71 are fixedly connected with a T-frame, the vertical section of the T-frame is slidably connected to the inner wall of the movable groove, and the horizontal section of the T-frame is slidably connected to the lower surface of the rack 74. The movable groove and the T-frame cooperate to limit the moving path of the rack 74 to ensure the stable meshing of the rack 74 and the gear 72. A pull ring is fixedly connected to one end of the rack 74. When the rack 74 is pulled by the pull ring, the meshing transmission between the rack 74 and the gear 72 is used to make the gear 72 drive the rotating shaft 3 to rotate, thereby achieving the purpose of facilitating the rotation of the rotating shaft 3 and the rotating plate 4.

[0030] The cam 75 is pressed against the bottom surface of the slot 53 to press the rotating plate 4 against the bottom surface of the slot 53. The cam 75 is pressed against the bottom surface of the slot 53 to press the rotating plate 4 against the bottom surface of the slot 53. The cam 75 is pressed against the bottom surface of the slot 53 to press the rotating plate 4 against the bottom surface of the slot 53. After pressing for a slight distance, the pin groove on the rotating shaft 3 is matched with the thread grooves on both sides of the load-bearing frame 1, and the set screw 6 is screwed into the thread groove on one side. After one end of the set screw 6 passes through the pin groove, it is screwed into the thread groove on the other side, so that the set screw 6 limits the vertical movement of the rotating shaft 3 and the rotating plate 4. At this time, the pressing frame 75 can be released, and the rotating plate 4 continues to press the positioning block 51 downward, thereby increasing the friction between the positioning block 51 and the load-bearing frame 1, and improving the stability of the roller 2 installed on the energy storage box.

[0031] In summary, the working principle of this scheme is as follows: the positioning block 51 is fixedly installed at the bottom of the energy storage box, and the steps of installing the roller 2 on the energy storage box are as follows: insert the rotating plate 4 and the sleeve frame that overlap each other up and down into the inner groove 52 until the upper surface of the load-bearing frame 1 contacts the lower surface of the positioning block 51, pull the rack 74 to rotate the rotating shaft 3 90 degrees, and rotate the rotating plate 4 into the inner groove 53. At this time, the rotating plate 4 and the slot 53 cooperate to limit the vertical separation of the load-bearing frame 1 and the positioning block 51, and the sleeve frame and the inner groove 52 cooperate to limit the horizontal separation of the load-bearing frame 1 and the positioning block 51, so as to realize the clamping and fixing of the load-bearing frame 1 and the positioning block 51, and rotate the pressing frame 75 to make the pressing The frame 75 pushes the extension plate 71 in the direction away from the positioning block 51, and the extension plate 71 drives the rotating shaft 3 and the rotating plate 4 to move synchronously. After the rotating shaft 3 is pressed down a slight distance by the pressing frame 75, the rotating plate 4 is squeezed and matched with the bottom surface in the slot 53, and the fixing screw 6 is screwed into the threaded groove on one side of the load-bearing frame 1. After one end of the fixing screw 6 passes through the pin groove, it is screwed into the threaded groove on the other side of the load-bearing frame 1, so that the fixing screw 6 limits the vertical movement of the rotating shaft 3 and the rotating plate 4, and the rotating plate 4 continues to press the positioning block 51 downward, and the positioning block 51 presses the load-bearing frame 1 downward, thereby increasing the friction between the positioning block 51 and the load-bearing frame 1, and improving the stability of the roller 2 installed on the energy storage box.
