Description

Technical Field

[0001] This application relates to the field of operating platforms, and in particular to a foldable worktable. Background Technology

[0002] Foldable devices are increasingly used in various scenarios, including industrial production and daily life. Foldable workbenches can be stored away when not in use, reducing space occupation, and unfolded to form an operating surface when needed, meeting practical operational requirements. In existing technologies, to achieve the foldable function of a workbench, a multi-connector structure is typically used to store the supporting panel. This method involves setting multiple connectors between the supporting panel and other components, and these connectors are interconnected through numerous hinge points. When the workbench needs to be folded, the supporting panel can be folded away by rotating and moving these connectors; it is then unfolded when needed.

[0003] However, these existing conventional methods have significant drawbacks. Multi-connector structures not only occupy a large space, but also have numerous hinge points between the connectors, which are prone to wear after prolonged use. Wear at the hinge points can cause jamming when unfolding or retracting the worktable, affecting the smoothness of operation. Furthermore, the additional fasteners used to lock the supporting panel increase the complexity of the operation and the equipment. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a foldable worktable.

[0005] A foldable workbench, comprising: Two parallel and vertically arranged support plates; A support panel is disposed between the two support plates, and Connector, the connector connecting the support plate and the load-bearing panel; Each of the support plates is provided with a sliding groove that has both guiding and locking functions. A part of the connector moves along the sliding groove to guide the carrier panel to switch between a folded position stored between the two support plates and a working position that is unfolded to form an operating plane. The sliding groove includes a stop part. When a part of the connector moves to the stop part, the carrier panel is locked in the working position.

[0006] By adopting the above solution, the bearing panel is flipped over, allowing the connector to slide along the sliding groove. The connector drives the bearing panel to unfold or fold, resulting in a simpler structure, less space occupation, and smoother unfolding and storage process. The bearing panel's bearing state is locked by the cooperation of the stop part and the connector, eliminating the need for additional fasteners to lock the bearing panel.

[0007] In one embodiment, the connector includes a first pin rotatably connected to both sides of the support panel, and connecting rods symmetrically rotatably connected to both sides of the support panel. The ends of the two connecting rods opposite to the support panel are respectively rotatably connected to the lower parts of the two support plates. The sliding groove also includes a sliding part for guiding the position switching of the support panel. The stop part is connected to the end of the sliding part near the bottom of the support plate. The stop part is in the shape of an upward-opening hook.

[0008] By adopting the above scheme, the first pin and the sliding groove cooperate to guide the folding trajectory of the bearing panel. The connecting rod is used to connect the bearing panel and the support plate, thereby supporting the bearing panel. When the bearing panel is in the bearing state, the side of the bearing panel away from the first pin is pressed, causing the first pin to tilt upward. The first pin is limited to the extended end of the stop part, so that the bearing panel is stably kept in the bearing state. When the side of the bearing panel close to the first pin is pressed, the first pin abuts against the bottom of the stop part, preventing the bearing panel from flipping backward. When the bearing panel needs to be folded, the bearing panel is flipped, causing the first pin to move along the hook-shaped stop part to the sliding part.

[0009] In one embodiment, a second pin is connected to both sides of the bearing panel. The end of the connecting rod away from the support plate is rotatably connected to the second pin. The support plate is provided with a slot. When the worktable is folded, the second pin engages with the slot.

[0010] By adopting the above solution, when the worktable is in a folded state, the second pin engages with the slot to limit the position of the load-bearing panel in the folded state.

[0011] In one embodiment, a rotating ring that mates with the sliding groove is fitted onto the outer circumferential surface of the first pin.

[0012] By adopting the above solution, when the first pin rubs against the inner wall of the sliding groove, the rotating ring rotates under the action of friction, avoiding wear on the first pin and making the unfolding of the worktable smoother.

[0013] In one embodiment, the inner wall surface of the stop portion is provided with a first damping sleeve, and when the first pin is located at the extended end of the stop portion, the rotating ring is in interference fit with the first damping sleeve.

[0014] By adopting the above solution, when the first pin slides too fast in the sliding groove, it is easy to collide with the stop part, causing the first pin to deform. The first damping sleeve can play a buffering role to prevent the first pin from deforming. At the same time, when the first pin moves to the extension end of the stop part, the first damping sleeve can limit the rotating ring, making the load-bearing panel in the unfolded state more stable.

[0015] In one embodiment, a second damping sleeve is provided in the slot, and the second pin is interference-fitted with the second damping sleeve.

[0016] By adopting the above solution, wear between the second pin and the second damping sleeve is avoided, and the connection between the second pin and the second damping sleeve is made tighter, making the load-bearing panel in the folded state more stable.

[0017] In one embodiment, the sliding portion has a bent portion at one end away from the stop portion, and the line connecting the extended end of the bent portion and the extended end of the slot is parallel to the length direction of the support plate.

[0018] By adopting the above solution, when the support panel is in a folded state, the extended end of the sliding part and the extended end of the slot limit the support panel at two points, so that the support panel in the folded state is parallel to the length direction of the support plate, preventing the support panel from tilting and causing incomplete storage.

[0019] In one embodiment, the extended end of the bend is provided with a third damping sleeve.

[0020] By adopting the above solution, excessive force applied by the user can be avoided, which could cause the first pin to collide with the extended end of the bent section.

[0021] In one embodiment, the end of the support panel opposite to the first pin is provided with a tool support groove.

[0022] By adopting the above solution, the tool support groove is used to support the tool and prevent the tool from slipping off during operation.

[0023] In one embodiment, the opening edge of the tool support groove is rotatably connected to the top edge of the support panel, and the two ends of the tool support groove are provided with abutment rods. When the worktable is folded, the abutment rods abut against the support plate, and the plane where the opening of the tool support groove is located is perpendicular to the plane where the support panel is located.

[0024] By adopting the above solution, since there will be debris on the surface of the support panel during operation, when the workbench is folded from the unfolded state, the support plate pushes the abutment rod, so that the plane where the opening of the tool support groove is located is perpendicular to the plane where the support panel is located. The debris will fall into the tool support groove under the action of gravity, making it easy for the user to clean it up.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By flipping the carrier panel, the connector slides along the sliding groove. The connector drives the carrier panel to unfold or fold, making the structure simpler and taking up less space. At the same time, it can ensure a smoother unfolding and storage process. The carrier panel is locked in its bearing state through the cooperation of the stop part and the connector, without the need for additional fasteners to lock the carrier panel.

[0026] 2. The first pin and the sliding groove cooperate to guide the folding trajectory of the bearing panel. The connecting rod is used to connect the bearing panel and the support plate, thereby supporting the bearing panel. When the bearing panel is in the bearing state, the side of the bearing panel away from the first pin is pressed, causing the first pin to tilt upward. The first pin is limited to the extended end of the stop part, so that the bearing panel is stably kept in the bearing state. When the side of the bearing panel close to the first pin is pressed, the first pin abuts against the bottom of the stop part, preventing the bearing panel from flipping backward. When the bearing panel needs to be folded, the bearing panel is flipped, causing the first pin to move along the hook-shaped stop part to the sliding part.

[0027] 3. Since there will be debris on the surface of the support panel during operation, when the workbench is folded from the unfolded state, the support plate pushes the abutment rod, so that the plane where the opening of the tool support groove is located is perpendicular to the plane where the support panel is located. The debris will fall into the tool support groove under the action of gravity, making it easy for the user to clean it up. At the same time, the tool support groove can also be used to support tools and prevent the tools from slipping during operation. Attached Figure Description

[0037] This application provides a foldable workbench with a simple structure and small footprint.

[0038] Example 1 Please see Figure 1-2 , Figure 1 This is a schematic diagram of the unfolded state of a foldable workbench provided in the first embodiment of this application. The foldable workbench provided in the first embodiment of this application includes two parallel and vertically arranged support plates 1, a load-bearing panel 2 disposed between the two support plates 1, and a connector 3 connecting the support plates 1 and the load-bearing panel 2. The support plates 1 are provided with a sliding groove 11 that serves both guiding and locking functions. A portion of the connector 3 moves along the sliding groove 11, guiding the load-bearing panel 2 to switch between a folded position and a working position. The sliding groove 11 includes a stop portion 111. When a portion of the connector 3 moves to the stop portion 111, it locks the load-bearing panel 2 in the working position. This application eliminates the need for multiple connectors 3 and numerous hinge points, achieving folding and locking functions through the cooperation of the sliding groove 11 and the connector 3. This simplifies the structure, reduces space occupation, ensures smooth operation, and eliminates the need for additional locking of the load-bearing panel 2.

[0039] Please refer to the following: Figure 3-4 , Figure 3 yes Figure 1 An enlarged view of area A. The connecting component 3 includes a first pin 31 rotatably connected to both sides of the supporting panel 2, and connecting rods 32 symmetrically rotatably connected to both sides of the supporting panel 2. The first pin 31 is typically made of metal, such as stainless steel, and has a cylindrical rod structure. This shape facilitates mating with the sliding groove 11 and can stably drive the supporting panel 2 to move. One end of the first pin 31 is provided with an external thread for fixing to both sides of the supporting panel 2. A rotating ring 311 is sleeved on the outer circumference of the first pin 31. The rotating ring 311 is a bearing and fits tightly with the first pin 31. When the first pin 31 slides within the sliding groove 11, the rotating ring 311 rotates under frictional force, preventing the first pin 31 from directly rubbing against the inner wall of the sliding groove 11 and causing wear.

[0040] The connecting rod 32 is typically made of metal, such as aluminum alloy, and is shaped like a long rod with holes at both ends for rotatable connection. One end of the connecting rod 32 is rotatably connected to the bearing panel 2, and the other end is rotatably connected to the lower part of the support plate 1, thus supporting the bearing panel 2. The connecting rod 32 can also be made of carbon fiber to reduce weight. The first pin 31 is rotatably connected to the bearing panel 2 through a pin hole, and the connecting rod 32 is rotatably connected to both the bearing panel 2 and the support plate 1 through a rotating shaft.

[0041] The first pin 31 cooperates with the sliding groove 11 to guide the folding trajectory of the supporting panel 2. The connecting rod 32 connects the supporting panel 2 and the support plate 1, providing support. The stop part 111 is hook-shaped. When the supporting panel 2 is in the load-bearing state, the side of the supporting panel 2 away from the first pin 31 is pressed, causing the first pin 31 to tilt upwards and be limited to the extended end of the stop part 111, thereby keeping the supporting panel 2 stably in the load-bearing state. The stop part 111 limits the first pin 31, preventing accidental movement of the supporting panel 2. When the side of the supporting panel 2 close to the first pin 31 is pressed, the first pin 31 abuts against the bottom of the stop part 111, preventing the supporting panel 2 from flipping backward. When the supporting panel 2 needs to be folded, it is flipped, and the first pin 31 moves along the hook-shaped stop part 111 to the sliding part 112, thereby folding.

[0042] The inner wall of the stop portion 111 is provided with a first damping sleeve 1111, which is generally made of rubber material and has a certain elasticity and cushioning performance. When the first pin 31 is located at the extended end of the stop portion 111, the rotating ring 311 is interference-fitted with the first damping sleeve 1111. Since the first pin 31 is prone to collision with the stop portion 111 when it slides too fast in the sliding groove 11, causing the first pin 31 to deform, the first damping sleeve 1111 can play a cushioning role to prevent the first pin 31 from deforming. At the same time, when the first pin 31 moves to the extended end of the stop portion 111, the first damping sleeve 1111 can limit the rotating ring 311, making the support panel 2 in the unfolded state more stable.

[0043] Please refer to the following: Figure 5 , Figure 5 yes Figure 1An enlarged view of area B. Second pins 21 are connected to both sides of the support panel 2. The end of the connecting rod 32 facing away from the support plate 1 is rotatably connected to the second pin 21. The support plate 1 has a slot 12. The second pin 21 is also made of metal, and its structure is basically the same as the first pin 31. The slot 12 is generally a groove opened on the support plate 1, and its shape is adapted to the second pin 21. When the worktable is folded, the second pin 21 cooperates with the slot 12. The slot 12 restricts the second pin 21, preventing the support panel 2 from shaking freely in the folded state, thus limiting the position of the support panel 2 in the folded state.

[0044] A second damping sleeve 121 is provided inside the slot 12. The second damping sleeve 121 is usually made of rubber, is annular, and fits tightly against the inner wall of the slot 12. When the worktable is folded, the second pin 21 and the second damping sleeve 121 are interference-fitted to avoid wear between the second pin 21 and the slot 12, and at the same time, to make the connection between the second pin 21 and the slot 12 tighter, so that the load-bearing panel 2 in the folded state is more stable.

[0045] The sliding groove 11 also includes a sliding part 112 for guiding the position switching of the support panel 2. A stop part 111 is connected to one end of the sliding part 112 near the bottom of the support plate 1, and the stop part 111 is a hook shape with the opening facing upward. The sliding part 112 is a smooth channel, and its shape is designed according to the movement trajectory of the support panel 2, which can guide the first pin 31 to move smoothly. The hook-shaped design of the stop part 111 can lock the first pin 31 when the support panel 2 is in the working position, and can also allow the first pin 31 to move smoothly to the sliding part 112 when folding is required.

[0046] Please refer to the following: Figure 6 , Figure 6 yes Figure 1 An enlarged view of region C. The sliding part 112 has a bent part 113 at one end away from the stop part 111. The line connecting the extended end of the bent part 113 and the extended end of the slot 12 is parallel to the length direction of the support plate 1. When the supporting panel 2 is in a folded state, the extended ends of the sliding part 112 and the slot 12 provide two-point positioning for the supporting panel 2, thereby ensuring that the supporting panel 2 in the folded state is parallel to the length direction of the support plate 1, preventing the supporting panel 2 from tilting and resulting in incomplete storage.

[0047] The extended end of the bend is provided with a third damping sleeve 1131, which is generally made of rubber and is shaped to fit the end of the bend. When the first pin 31 moves to the end of the bend, the third damping sleeve 1131 can prevent the user from applying too much force, which could cause the first pin 31 to collide with the extended end of the bend.

[0048] The working principle of this embodiment is as follows: The foldable worktable, through the cooperation of the connector 3 and the sliding groove 11, eliminates the traditional design of multiple connectors 3 and numerous hinge points, resulting in a simpler structure and smaller space occupation. The cooperation between the first pin 31 and the sliding groove 11 guides and locks the folding trajectory of the support panel 2, while the connecting rod 32 provides support for the support panel 2. The cooperation between the second pin 21 and the slot 12 limits the position of the support panel 2 in the folded state. The inclusion of components such as the rotating ring 311 and the damping sleeve improves the smoothness of operation and the durability of the components.

[0049] Example 2 Please see Figure 7 , Figure 7 This is a schematic diagram of the unfolded state of the tool support groove 22 according to the second embodiment of this application. The structure of this embodiment is basically the same as that of the above embodiments, except that the tool support groove 22 is provided at the end of the support panel 2 away from the first pin 31. The tool support groove 22 is generally made of plastic or metal and is rectangular in shape. It is used to support tools and prevent them from slipping during operation. The replaceable tool support groove 22 can be a groove with a divider for better classification and placement of tools.

[0050] Please refer to the following: Figure 8 , Figure 8 This is a schematic diagram of the folded state of the tool support groove 22 according to the second embodiment of this application. The opening edge of the tool support groove 22 is rotatably connected to the top edge of the support panel 2, and the two ends of the tool support groove 22 are provided with abutment rods 221. The abutment rods 221 are usually metal rods, straight in shape, and fixed at both ends of the tool support groove 22. When the workbench is folded, the abutment rods 221 abut against the support plate 1, making the plane where the opening of the tool support groove 22 is located perpendicular to the plane where the support panel 2 is located. When the workbench is used as a writing surface, there will be eraser shavings on its surface. When the workbench is used as a processing surface, there will be metal shavings on its surface. When the workbench is folded from the unfolded state, the support plate 1 presses against the abutment rods 221, causing the tool support groove 22 to rotate. The residual shavings during work fall into the tool support groove 22 under the action of gravity, making it convenient for the user to collect and dispose of them.

[0051] The working principle of this embodiment is as follows: the tool support groove 22 is rotatably connected to the support panel 2, which can realize two functions. When the support panel 2 is unfolded, it is convenient to place the tool. When the support panel 2 is folded, the support plate 1 pushes the tool support groove 22 to rotate, so that the debris left during the operation falls into the tool support groove 22 under the action of gravity, which is convenient for cleaning the debris on the support panel 2.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
