DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The present application embodiment discloses a modular sheet metal frame. Figure 1, including a frame body 1, the lower end of the frame body 1 is connected with a support frame 2, the support frame 2 supports the frame body 1 so that the frame body 1 is away from the ground, the lower end of the support frame 2 is connected with a moving wheel 4, the moving wheel 4 slides to facilitate the frame body 1 to move according to practical needs, one side of the support frame 2 is connected to a limiting component 3, the limiting component 3 includes a rotating shaft 31 installed between two adjacent support frames 2, one side of the outer side of the rotating shaft 31 is sleeved with a rotating sleeve 32, the rotating sleeve 32 facilitates the rotation of the rotating shaft 31, and both sides of the outer side of the rotating shaft 31 are sleeved with a worm 33, one side of the worm 33 is meshedly connected with a worm wheel 34, the worm 33 is meshedly connected with the worm wheel 34, the rotation of the worm 33 drives the worm wheel 34 to rotate, and plays a transmission role, and at the same time, the worm 33 and the worm wheel 34 have a self-locking function.

[0019] Reference Figure 2-3 A screw rod 35 is connected to one side of the worm gear 34, and one end of the screw rod 35 extends through and extends to the outside of the support frame 2 and is connected to a mounting frame 36. The mounting frame 36 installs and fixes the screw rod 35 and the limit plate 37 to make the screw rod 35 more stable during the rotation process. One end of the mounting frame 36 is connected to one side of the support frame 2, and a movable plate 315 is sleeved on the outside of the screw rod 35. One end of the movable plate 315 is connected through and connected to the limit plate 37. The limit plate 37 limits and fixes the movable plate 315 so that the movable plate 315 can only move in a straight line during movement. One end of the limit plate 37 is connected to one side of the support frame 2, and the other end of the limit plate 37 is connected to one side of the mounting frame 36. One end of the movable plate 315 is connected to an arc plate 38, and the arc plate 38 has an arc structure. The arc plate 38 is arranged to be conveniently fitted with the moving wheel 4. A brake strip 39 is connected to the inner side of the arc plate 38. The brake strip 39 contacts the outer side of the moving wheel 4 to increase the friction force and limit the moving wheel 4.

[0020] The implementation principle of a modular sheet metal frame in the embodiment of the present application is as follows: when in use, when it is necessary to fix and limit the moving wheel 4, the rotating sleeve 32 is rotated, the rotating sleeve 32 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the worm 33 to rotate, the worm 33 is meshed and connected with the worm wheel 34, the worm wheel 34 drives the screw rod 35 to rotate, the screw rod 35 is threadedly connected with the moving plate 315, and at the same time, under the limiting action of the limiting plate 37, the moving plate 315 drives the arc plate 38 to move along a straight line. When the arc plate 38 moves to the outside of the moving wheel 4, Because one end of the friction plate 314 is arranged in an arc-shaped structure, under the arc-shaped structure of the friction plate 314, the clamping plate 313 is expanded to both sides, the clamping plate 313 drives the pulling plate 310 to move, and the pulling plate 310 pulls the spring 311, so that the spring 311 is in a stretched state, and the clamping plate 313 is tightened under the elastic potential energy of the spring 311, so that the clamping plate 313 is tightly fitted with the outer side of the moving wheel 4, and at the same time, the brake strip 39 is in contact with the outside of the moving wheel 4 to increase the friction force. Under the double limit fixation, the moving wheel 4 can be fixed or moved according to the use requirements.
