Description

Technical Field

[0001] This utility model relates to the field of workbench technology, specifically to a foldable workbench that can be used against a wall. Background Technology

[0002] Workbenches are essential equipment used in industrial production and handicraft manufacturing to support workpieces, tools, and operational processes. Traditional workbenches are mostly used independently and cannot be folded for storage, occupying already limited space when not in use.

[0003] Existing technologies have made some improvements to this. For example, the existing patent with publication number CN209769458U discloses a lockable wall-folding worktable. It uses wall hooks to connect the worktable to the wall, sets two of the table legs as movable legs, and uses hinges to achieve rotational hinges. The tabletop is also set as a hinge, realizing the folding function of the worktable. The unfolding and fixing of the worktable is achieved by rotating the positioning pin and inserting it into the positioning hole.

[0004] In the above structure, each folding and fixing is achieved by a spiral positioning pin, which is cumbersome to operate. In addition, the positioning pins are usually small and the operating space is limited, making it inconvenient to unfold or fold the worktable. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a foldable workbench that can be used against a wall. By setting an elastically pluggable unfolding and fixing structure, the workbench can be quickly switched between folded and unfolded states, improving ease of use.

[0006] To solve the above problems, the present invention adopts the following solution: A foldable workbench for wall mounting is provided. It is connected to a wall surface and includes a table frame and a tabletop mounted on the table frame. The table frame includes fixed legs and movable legs on both sides of the fixed legs. The movable legs support the lower end of the tabletop, and both the movable legs and the tabletop are rotatably hinged to the fixed legs to achieve foldable storage. An unfolding and fixing structure is also provided between the movable legs and the tabletop, including an elastic positioning pin movably inserted through the upper part of the movable legs and a positioning hole at the lower end of the tabletop. The elastic positioning pin can be detachably inserted into the positioning hole. The elastic positioning pin is also fitted with a telescopic spring, and both are installed together in the mounting hole of the movable legs. When the tabletop is in its fully unfolded state with its lower end positioned above the movable legs, the mounting hole and the positioning hole are coaxially aligned.

[0007] In the above solution, the unfolding and fixing structure can be used to quickly switch between the unfolded and folded states of the workbench. When folding is required, the elastic positioning pin can be pulled down to disengage it from the positioning hole, thereby releasing the lock between the desktop and the movable legs. Then, the workbench can be folded and stored by using the hinged connection between the desktop, the movable legs and the fixed legs. At this time, the elastic positioning pin also moves up under the rebound force of the telescopic spring, returning to the initial state. When it needs to be unfolded, the desktop and movable legs can be unfolded in sequence. Since the mounting holes and positioning holes are coaxially set when unfolded, the spring-loaded positioning pin can automatically spring into the positioning hole when fully unfolded, thereby locking the desktop and movable legs and ensuring the stability of the workbench when unfolded. The above operations are simple and convenient, allowing for quick locking and unlocking, greatly improving the ease of unfolding and folding the workbench.

[0008] Preferably, the lower end of the elastic positioning pin is also provided with a pull ring, which is exposed outside the mounting hole to facilitate operation by the user, allowing the elastic positioning pin to be quickly pulled down by the pull ring.

[0009] Preferably, the movable legs include a longitudinally arranged movable leg, a desktop support rod and a hinged support rod, all of which are perpendicularly connected to the movable leg. The mounting hole is longitudinally opened in the desktop support rod. The desktop support rod and the hinged support rod are both rotatably hinged to the fixed legs through hinge seats, and the rotation direction is left and right.

[0010] The above solution achieves the rotatable hinge connection between the movable and fixed legs through the hinge seat, thereby enabling the movable leg to be folded and stored.

[0011] Preferably, the desktop is connected to the fixed leg via a hinged bracket, and when the workbench is fully extended, the three are perpendicular to each other. The hinged bracket is fixedly connected to the fixed leg, and the hinged bracket is rotatably hinged to the desktop, with the rotation direction being up and down.

[0012] This design allows for the folding and storage of the desktop panel.

[0013] Preferably, when the movable legs are fully extended, the outer wall of the desktop support rod abuts against the inner wall of the hinged bracket.

[0014] The design of this solution allows the hinged support plate to also limit the rotation of the movable legs. That is, when the movable legs rotate to the point where they abut against the hinged support plate, the movable legs can no longer rotate outwards, and at this point the workbench is fully extended.

[0015] Preferably, the fixed bracket includes two longitudinally arranged support legs and a reinforcing support rod connected between the two support legs. The support legs extend upward to form an extension connecting rod. A perforated plate is detachably connected between the two extension connecting rods. The perforated plate is evenly provided with multiple through holes. The through holes can be used to directly or through Y-shaped hooks to hook working tools, parts, materials, etc.

[0016] The above-mentioned design, including the addition of a perforated plate, makes the workbench more versatile and versatile, facilitating the placement of tools and parts, and improving the ease of use during operation.

[0017] Preferably, a storage box is provided between the two extended connecting rods. The storage box is located between the perforated plate and the desktop plate, and a gap is left between the storage box and the side wall of the desktop plate.

[0018] The included storage box can be used to store small parts such as screws and nuts, further improving the ease of use of this workbench.

[0019] Preferably, the extension connecting rod is also provided with connecting through holes passing through its front and rear ends, through which an expansion nut is passed and embedded in the wall.

[0020] The above setup connects the workbench to the wall, improving its overall stability. When the workbench is folded and stored, it rests directly against the wall, eliminating the need to move it to a corner and improving ease of use.

[0021] As a preferred option, this workbench is also equipped with multiple fixed hooks to enable different ways of connecting the workbench to the wall. The fixed hooks include a base plate and two vertical plates of different lengths to form an installation space. The storage box is placed into the installation space, and the two are fitted together with a gap. The longer vertical plate is connected to the wall by a bolt structure.

[0022] In the above setup, the fixed hook is attached to the wall, and the storage box is placed into the installation space, thereby connecting the workbench to the wall via the fixed hook.

[0023] The beneficial effects of this utility model are as follows: This utility model utilizes an unfolding and fixing structure to achieve rapid switching between the unfolded and folded states of the workbench. Specifically: When folding is required, pull down the pull ring to disengage the elastic positioning pin from the positioning hole, quickly release the lock between the desktop and the movable legs, then fold the two movable legs in sequence and flip the desktop downwards to fold and store the workbench. At this time, the elastic positioning pin moves upwards under the rebound force of the telescopic spring, returning to its initial state. When it needs to be unfolded, the desktop and movable legs can be unfolded in sequence. Since the mounting holes and positioning holes are coaxially set when unfolded, the spring-loaded positioning pin can automatically spring into or insert into the positioning hole when fully unfolded, so as to quickly lock the desktop and movable legs and ensure the stability of the workbench when unfolded. The above operation is simple and convenient, allowing for quick unlocking or locking of the desktop and movable legs, and then folding or unfolding the workbench, greatly improving the ease of operation for unfolding and folding the workbench.

[0024] This invention also achieves a fixed connection between the workbench and the wall by using a connecting through hole and an expansion nut that cooperate with each other, or a fixed hook and a storage box, thereby improving the stability of the workbench in use. Attached Figure Description

Detailed Implementation

[0027] Example 1: refer to Figure 1 , Figure 2 This embodiment provides a foldable workbench for wall mounting. It is connected to the wall to improve the overall stability of the workbench. It includes a table frame 10 and a desktop board 20 installed on the table frame 10. The table frame 10 includes a fixed leg 11 and movable legs 12 located on both sides of the fixed leg 11. The movable legs 12 are supported on the lower end of the desktop board 20. Both the movable legs 12 and the desktop board 20 are rotatably hinged to the fixed leg 11 to realize the foldable storage of the workbench.

[0028] refer to Figure 2 The movable legs 12 and the desktop 20 are further provided with an unfolding and fixing structure 30, which can be used to quickly switch the unfolded and folded states of the workbench, so that the workbench can maintain a stable unfolded state. (See reference) Figures 3-5 It includes an elastic positioning pin 31 that is movably inserted into the upper part of the movable leg 12 and a positioning hole 32 opened at the lower end of the desktop 20. The elastic positioning pin 31 can be detachably inserted into the positioning hole 32.

[0029] Furthermore, the elastic positioning pin 31 is also fitted with a telescopic spring 33, and both are installed together in the mounting hole 34 of the movable leg 12. The elastic positioning pin 31 includes an upper half 311 with a larger diameter and a lower half 312 with a smaller diameter. Therefore, the diameters of the upper and lower ends of the mounting hole 34 correspond to the diameters of the upper half 311 and the lower half 312. The telescopic spring 33 is fitted onto the lower half 312 and abuts against the lower bottom wall of the mounting hole 34. When the desktop panel 20 is in its fully extended state with its lower end positioned above the movable leg 12, the mounting hole 34 and the positioning hole 32 are coaxially aligned.

[0030] The working principle of the aforementioned unfolding and fixing structure 30 is as follows: By pulling down the elastic positioning pin 31, it is disengaged from the positioning hole 32, thereby quickly releasing the lock between the desktop 20 and the movable leg 12, and then folding the worktable; since the mounting hole 34 and the positioning hole 32 are coaxially set in the unfolded state, when fully unfolded, the elastic positioning pin can automatically spring into or automatically insert into the positioning hole 32, realizing the quick locking of the desktop 20 and the movable leg 12.

[0031] refer to Figure 3 To further improve the ease of operation of pulling down the elastic positioning pin 31, a pull ring 35 is also provided at the lower end of the elastic positioning pin 31. The pull ring 35 is exposed outside the mounting hole 34 to facilitate operation by the user, allowing the elastic positioning pin 31 to be pulled down quickly via the pull ring 35.

[0032] The specific structure of the hinged connection between the movable leg 12 and the desktop 20 and the fixed leg 11 is as follows: refer to Figures 1-2The movable legs 12 include longitudinally arranged movable legs 121, desktop support rods 122 and hinged support rods 123 all perpendicularly connected to the movable legs 121, wherein mounting holes 34 are longitudinally formed in the desktop support rods 122 (e.g., ...). Figure 4 (as shown), reference Figure 7 Both the desktop support rod 122 and the hinged support rod 123 are rotatably hinged to the fixed leg 11 via the hinge seat 41, and the rotation direction is left and right. Specifically, the hinge seat 41 can be fixedly connected to the fixed leg 11 by welding or other means, and then rotatably hinged to the desktop support rod 122 or the hinged support rod 123 via the hinge shaft.

[0033] refer to Figure 7 The desktop panel 20 is connected to the fixed leg 11 via a hinged bracket 42. When the workbench is fully extended, the three are perpendicular to each other. The hinged bracket 42 and the fixed leg 11 can be fixedly connected by screws or the like. The hinged bracket 42 and the desktop panel 20 can be rotatably hinged by a hinge shaft, and the rotation direction is up and down.

[0034] refer to Figure 1 and Figure 6 In the above structure, the workbench can be folded and stored by rotating the two movable legs 12 inward and then flipping the desktop 20 downward.

[0035] refer to Figure 1 , Figure 7 Furthermore, when the movable leg 12 is fully extended, the outer wall of the desktop support rod 122 abuts against the inner wall of the hinge bracket 42. Therefore, the hinge bracket 42 also has a limiting effect on the rotation of the movable leg 12. That is, when the movable leg 12 rotates outward to abut against the hinge bracket 42, the movable leg 12 can no longer rotate outward, and at this moment the workbench is fully extended.

[0036] To further improve the ease of operation of this workbench, it is also equipped with a component for hooking tools and materials, as well as for placing small parts such as screws, the structure of which is as follows.

[0037] refer to Figure 1 , Figure 2 The fixed stand 11 includes two longitudinally arranged support legs 111 and a reinforcing support rod 112 connected between the two support legs 111. The support legs 111 extend upward and form an extension connecting rod 113. A perforated plate 50 is detachably connected between the two extension connecting rods 113. A plurality of through holes 51 are evenly distributed on the perforated plate 50. The through holes 51 can be used to hook tool parts directly or through Y-shaped hooks, etc.

[0038] refer to Figure 1A storage box 60 is provided between the two extended connecting rods 113. The storage box 60 is located between the perforated plate 50 and the desktop 20, and a gap is left between the storage box and the side wall of the desktop 20. The storage box 60 can be used to store small parts such as screws and nuts, further improving the ease of use of this workbench.

[0039] This embodiment also achieves the connection and fixation between the workbench and the wall through the following structure.

[0040] refer to Figure 2 One of the connection and fixing methods is as follows: the extension connecting rod 113 is provided with a connecting through hole 71 passing through its front and rear ends, and the expansion nut 72 is passed through the connecting through hole 71 and embedded in the wall.

[0041] Therefore, this method connects the workbench to the wall, improving its overall stability. Furthermore, when folded and stored, the workbench rests directly against the wall, eliminating the need to move it to a corner and further enhancing ease of use. This connection method uses fewer parts and is simpler and more convenient to operate, but it is not easy to detach from the wall.

[0042] refer to Figure 1 and Figure 8 Another connection and fixing method is: equipped with multiple fixing hooks 80, each fixing hook 80 including a base plate 81 and two vertical plates 82 of different lengths to form an installation space 83. The width of the base plate 81 is slightly larger than the width of the bottom surface of the storage box 60, so it is convenient to place the storage box 60 into the installation space 83. The longer vertical plate 82 is then connected to the wall by a bolt structure, which can be an expansion bolt.

[0043] Therefore, the fixed hook 80 is attached to the wall, and the storage box 60 is placed into the installation space 83, thus connecting the workbench to the wall. Although this connection method is more complicated, it facilitates separation from the wall. When separation is required, the workbench can be detached from the installation space 83 directly or by damaging the fixed hook 80 to increase the installation space 83 without damaging the workbench.

[0044] The unfolding and folding process of the worktable in this embodiment is as follows: When folding is required, pull down the pull ring 35 to disengage the elastic positioning pin 31 from the positioning hole 32, release the locking between the desktop 20 and the movable legs 12, then fold the two movable legs 12 in sequence and flip the desktop 20 downward to achieve quick folding of the workbench and place it stably against the wall. At this time, the elastic positioning pin 31 moves upward under the rebound force of the telescopic spring 33 and returns to the initial state. When unfolding is required, the operation can be reversed, unfolding the desktop panel 20 and the movable leg 12 in sequence. Since the mounting hole 34 and the positioning hole 32 are already coaxially arranged in the unfolded state, when fully unfolded, the elastic positioning pin 31 can be adjusted according to whether it exceeds the lower end of the desktop panel 20 (e.g., ...). Figure 4 , Figure 5 As shown, these are the two states of not exceeding and exceeding, respectively. The desktop panel 20 is automatically inserted or automatically popped into the positioning hole 32 to achieve quick locking between the desktop panel 20 and the movable leg 12, ensuring the stability of the workbench when unfolded.
