Description

Technical Field

[0001] This utility model relates to the technical field of universal caster frames, and in particular to a universal caster frame with anti-slip function. Background Technology

[0002] A swivel caster bracket is a support for mounting swivel casters. The swivel caster bracket allows objects mounted on it to rotate and move freely 360 degrees, greatly improving the flexibility of movement and facilitating position adjustments in different directions and confined spaces.

[0003] Current swivel caster brackets, when needed to be fixed in one position, are operated by pressing down the locking pedal, which rotates downwards to lock the casters and prevent them from rotating, thus fixing the position. However, if the casters are in a special position such as on a slope, even if the casters are locked and cannot rotate, gravity will still cause them to slide downwards. As a result, the swivel caster bracket cannot stay stably in the intended position, thus reducing its working efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a universal caster frame with anti-slip function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A universal caster bracket with anti-slip function includes a fixed frame. The outer wall of the fixed frame is rotatably connected to a locking pedal via a pin. The fixed frame is made of magnetically attractive metal. The lower end of the locking pedal is movably connected to a first connecting rod. The other end of the first connecting rod is rotatably connected to a stop block via a pin. The outer wall of the stop block is rotatably connected to a second connecting rod via a pin.

[0007] Preferably, the outer wall of the abutment block contacts the universal wheel, the universal wheel is rotatably connected to the fixed frame through a bearing, and the surface of the abutment block in contact with the universal wheel is machined into an arc shape with the diameter of the arc being the same as that of the universal wheel.

[0008] Preferably, the outer wall of the fixing frame is threadedly connected to the fixing bolt through an opening, the fixing bolt passes through the protective plate through a through hole, and the outer wall of the protective plate is in contact with the outer wall of the fixing frame.

[0009] Preferably, the upper end of the fixed frame is rotatably connected to the bracket via a bearing, the surface of the bracket is machined with external threads, and the bracket is threadedly connected to the movable block via the external threads.

[0010] Preferably, a magnetic strip is installed on the lower surface of the locking pedal, and the size of the magnetic strip matches the size of the fixing frame.

[0011] Preferably, the other end of the second connecting rod is rotatably connected to the fixed frame via a pin.

[0012] Preferably, the protective plate is fan-shaped and its diameter is larger than that of the caster wheel.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. With the fixed frame, locking pedal, first link, abutment block, and second link set up, when it is necessary to fix the position of the swivel caster frame, the operator steps down on the locking pedal. The locking pedal rotates on the fixed frame, which in turn drives the first link to rotate. The first link drives the abutment block to move downward, and the abutment block drives the second link to rotate. When the locking pedal contacts the swivel caster and locks it, the first link drives the abutment block to move below the swivel caster, so that the inclined surface of the abutment block abuts the swivel caster. Since the diameter of the inclined surface of the abutment block is the same as that of the swivel caster, the abutment block will block the back of the swivel caster, preventing it from sliding due to gravity, thereby improving the working efficiency of the swivel caster frame.

[0015] 2. By using fixed bolts and protective plates, the protective plates are installed on the fixed frame. When there is an obstacle blocking the front of the caster, the protective plates can push the obstacle away, thus allowing the caster to move stably. At the same time, the protective plates can also prevent the caster from hitting the obstacle and causing damage, which reduces the maintenance cost of the caster frame. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A universal caster bracket with anti-slip function includes a fixed frame 2. The outer wall of the fixed frame 2 is rotatably connected to a locking pedal 5 via a pin. The locking pedal 5 rotates on the fixed frame 2. The fixed frame 2 is made of a magnetic metal material, so that a magnetic strip 6 can be attracted to the fixed frame 2. The lower end of the locking pedal 5 is movably connected to a first connecting rod 7. The locking pedal 5 can drive the first connecting rod 7 to move. The other end of the first connecting rod 7 is rotatably connected to a pressing block 8 via a pin. The first connecting rod 7 drives the pressing block 8 to move. The outer wall of the pressing block 8 is rotatably connected to a second connecting rod 9 via a pin. When the pressing block 8 moves, it drives the second connecting rod 9 to rotate. When the position of the swivel caster needs to be fixed, the operator steps down on the locking pedal 5. The locking pedal 5 rotates on the fixing frame 2, simultaneously rotating the first connecting rod 7. The first connecting rod 7 moves the abutment block 8 downwards, and the abutment block 8 simultaneously rotates the second connecting rod 9. When the lower end of the locking pedal 5 contacts the swivel wheel 1 and locks it, the first connecting rod 7 moves the abutment block 8 below the swivel wheel 1, so that the inclined surface of the abutment block 8 presses against the swivel wheel 1. Since the diameter of the inclined surface of the abutment block 8 is the same as that of the swivel wheel 1, the abutment block 8 will block the rear of the swivel wheel 1, preventing it from sliding due to gravity, thereby improving the working efficiency of the swivel caster.

[0024] In this embodiment, the outer wall of the abutment block 8 contacts the universal wheel 1. The abutment block 8 can prevent the universal wheel 1 from moving downwards due to gravity. The universal wheel 1 is rotatably connected to the fixed frame 2 through a bearing. The universal wheel 1 rotates on the fixed frame 2. The contact surface between the abutment block 8 and the universal wheel 1 is machined into an arc shape with the diameter of the arc being the same as that of the universal wheel 1, so that the abutment block 8 can stably contact the universal wheel 1. The outer wall of the fixed frame 2 is threadedly connected to the fixing bolt 10 through an opening. The fixing bolt 10 is tightened on the fixed frame 2. The fixing bolt 10 passes through the protective plate 11 through a through hole, fixing the protective plate 11 to the fixed frame 2. The outer wall of the protective plate 11 contacts the outer wall of the fixed frame 2, and the protective plate 11 is tightly attached to it. The fixed frame 2 is rotatably connected to the bracket 3 via a bearing at its upper end. The bracket 3 rotates on the fixed frame 2. The surface of the bracket 3 is machined with external threads. The bracket 3 is threadedly connected to the movable block 4 via the external threads. The movable block 4 moves on the bracket 3. A magnetic strip 6 is installed on the lower surface of the locking pedal 5. The magnetic strip 6 enables the locking pedal 5 to be fixed on the fixed frame 2 when it is reset. The size of the magnetic strip 6 matches the size of the fixed frame 2. The other end of the second connecting rod 9 is rotatably connected to the fixed frame 2 via a pin. The second connecting rod 9 rotates on the fixed frame 2. The protective plate 11 is fan-shaped and its diameter is larger than that of the universal wheel 1. This prevents the universal wheel 1 from rotating with the protective plate 11, making the universal wheel 1 rotate more smoothly.

[0025] The working principle of this embodiment is as follows: In use, the operator first moves the caster frame by pushing it. The caster frame is moved to a suitable position via the caster 1. When the caster frame is in the desired position and needs to be secured, the operator steps down on the locking pedal 5. The locking pedal 5 rotates on the fixing frame 2, simultaneously rotating the first connecting rod 7. The first connecting rod 7 moves the abutment block 8 downwards, and the abutment block 8 simultaneously rotates the second connecting rod 9. When the lower end of the locking pedal 5 abuts against the caster 1 and locks it in place, the first connecting rod 7 moves the abutment block 8 below the caster 1, so that the inclined surface of the abutment block 8 abuts against the caster 1. Since the diameter of the inclined surface of the abutment block 8 is the same as that of the caster 1, the abutment block 8 will... The rear of the caster wheel 1 is blocked to prevent it from sliding due to gravity, thus improving the working efficiency of the caster frame. When the caster frame needs to continue moving, the operator resets the locking pedal 5. The locking pedal 5 moves the abutment block 8 away from the caster wheel 1 through the above-mentioned transmission method. When the magnetic strip 6 on the surface of the locking pedal 5 contacts the metal fixing frame 2, the magnetic strip 6 fixes the locking pedal 5, thereby fixing the abutment block 8. This prevents the abutment block 8 from blocking the caster wheel 1 when it moves. At the same time, when the caster wheel 1 moves, the protective plate 11 can protect the caster wheel 1 from being damaged by the impact of obstacles, thereby reducing the maintenance cost of the caster frame.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
