Description

Technical Field

[0001] This invention relates to the field of teaching infrastructure, and more particularly to a desk that is easy to transport. Background Technology

[0002] Students need to use desks in class, but traditional desks have non-foldable legs, which take up a lot of space. During transportation, the non-foldable legs make the desks take up a lot of space on the transport vehicle, resulting in more trips and higher transportation costs. Moreover, the desks will move around due to bumps during transportation, so they need to be secured to prevent damage.

[0003] Patent publication number CN203762572U discloses a desk that occupies less space during transportation. The desk includes a desktop, with a drawer connected to the lower surface of the desktop. Table legs are provided on both sides of the drawer. Each table leg includes an upper table leg, a lower table leg, a first table leg support, and a second table leg support. The upper end of the upper table leg is rotatably connected to the side of the drawer, and the lower end of the upper table leg is rotatably connected to the upper end of the lower table leg. The first table leg support and the second table leg support are rotatably connected to the lower end of the lower table leg.

[0004] When the desk needs to have its legs folded, the fixing bolts need to be removed before the legs can be folded up. This requires manpower to remove the bolts, which is very inconvenient. As a result, the operation of folding the legs is labor-intensive, and the desk cannot be fixed in place, which can easily cause damage. Therefore, a desk that is easy to transport and has convenient folding legs and can be fixed in place was developed. Summary of the Invention

[0005] To overcome the drawbacks of requiring manpower to fold table legs and not being able to secure the desk during transportation, this invention provides a convenient desk with easily foldable legs that can be secured for easy transport.

[0006] A conveniently transportable desk includes a desktop, a drawer front, a drawer support frame, torsion spring hinges, a first rear leg, a second rear leg, a front leg, and inner legs. The drawer support frame is slidably connected to the rear side of the desktop. Torsion spring hinges are rotatably connected to the lower left and right sides of the drawer support frame. The drawer front is rotatably connected to the drawer support frame via torsion spring hinges. The first rear leg is rotatably connected to the rear left side of the desktop, and the second rear leg is connected to the rear right side of the desktop. Front legs are rotatably connected to the left and right sides of the front of the desktop. Inner legs are slidably connected to the lower parts of the first and second rear legs. Inner legs are also slidably connected to the lower parts of the two front legs. The desk also includes a leg-folding mechanism and a latching mechanism. A leg-folding mechanism is provided between the first rear leg, the second rear leg, and the front leg. A latching mechanism is provided in the middle of the rear side of the desktop.

[0007] To further explain, the folding leg mechanism includes a rotating connecting block. The first rear table leg, the second rear table leg, and the front table leg all have sliding grooves in their middle sections. The rotating connecting block is slidably connected to the two sliding grooves on the same side. The rotating connecting block is tightly fitted with the sliding groove and is rotatably connected to the inner table leg. The rotating connecting block is tightly fitted with the inner table leg. Through the rotating connecting block and the sliding groove, the second rear table leg and the front table leg on the same side are arranged in a cross configuration, and the first rear table leg and the front table leg on the same side are also arranged in a cross configuration.

[0008] To further explain, the buckle mechanism includes a clamping buckle and a first spring. The clamping buckle is slidably connected to the middle of the back side of the desk, and the first spring is connected to both the left and right sides between the clamping buckle and the desk.

[0009] To further explain, it also includes a folding mechanism, which includes folding rods, rotating pins, and ordinary hinges. Two folding rods are rotatably connected to the center of the left and right sides of the desktop via rotating pins. Two folding rods are also rotatably connected to the center of the left and right sides of the drawer via rotating pins. Ordinary hinges are connected between the two folding rods in the same vertical direction.

[0010] To further explain, it also includes a protective mechanism, which includes a wedge block and a second spring. The wedge block is slidably connected to both the left and right sides of the middle rear side of the desktop. The wedge block and the interior of the desktop are both connected to the second spring. The clamping buckle has slots on both the left and right sides of the front part. The slots and the wedge block engage with each other, and the clamping buckle and the wedge block are pressed together.

[0011] To further explain, it also includes a locking mechanism, which consists of locking blocks and a third spring. Two locking blocks are slidably connected to the upper part of each inner table leg, and a third spring is connected to both the upper and lower sides between the two locking blocks.

[0012] To further explain, it also includes a connecting mechanism, which includes a connector and a connecting torsion spring. The connector is connected inside the second rear table leg, and a connecting torsion spring is connected between the connector and the second rear table leg. A special groove is opened at the horizontal position of the first rear table leg and the connector.

[0013] To further explain, the second rear table leg and the front table leg on the same side are arranged in a triangular intersection, as are the first rear table leg and the front table leg on the same side.

[0014] The present invention has the following advantages: 1. The present invention moves the rotating connecting block upward by rotating the table legs, so that the table legs on both sides are in a horizontal state, and the rope passes through the clamping buckle by pulling out the clamping buckle, thereby fixing the position of the desk and preventing damage to the desk.

[0015] 2. This invention uses a regular hinge to fold the folding rod together, causing the drawer to fold upwards and close to the desktop. Under the action of the torsion spring hinge, the drawer support frame folds forward, thus the drawer and desktop are folded together perfectly, saving space.

[0016] 3. The present invention uses a wedge-shaped block to lock into the clamping buckle, thereby preventing the first spring from exceeding its elastic limit and thus preventing the desk from being fixed and avoiding damage to the desk.

[0017] 4. This invention locks the inner table legs with locking blocks, preventing the inner table legs from automatically retracting and folding upwards when many items are placed on the desk, thus avoiding instability of the desk.

[0018] 5. The present invention uses a connector to snap into a special groove, thereby allowing two desks to be fixed together, thus saving space in the transport vehicle and reducing transportation costs. Attached Figure Description

Detailed Implementation

[0031] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] A type of desk that is easy to transport, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the table includes a desktop 1, a drawer front 2, a drawer support frame 21, a torsion spring hinge 22, a first rear table leg 3, a second rear table leg 31, a front table leg 32, an inner table leg 33, a folding leg mechanism 4, and a latching mechanism 5. The drawer support frame 21 is slidably connected to the rear side of the desktop 1. The lower left and right sides of the drawer support frame 21 are rotatably connected to the torsion spring hinge 22. The drawer support frame 21 is rotatably connected to the drawer front 2 via the torsion spring hinge 22. The first rear table leg 3 is rotatably connected to the rear left side of the desktop 1, and the second rear table leg 31 is connected to the rear right side of the desktop 1. The table legs 31 and the front left and right sides of the tabletop 1 are rotatably connected to the front table legs 32. The tabletop 1 is tightly fitted with the front table legs 32. The lower parts of the first rear table legs 3 and the second rear table legs 31 are slidably connected to the inner table legs 33. The first rear table legs 3 and the second rear table legs 31 are tightly fitted with the inner table legs 33. The lower parts of the two front table legs 32 are also slidably connected to the inner table legs 33. The front table legs 32 are tightly fitted with the inner table legs 33. A leg-folding mechanism 4 is provided between the first rear table legs 3, the second rear table legs 31 and the front table legs 32. A buckle mechanism 5 is provided in the middle of the rear side of the tabletop 1.

[0034] like Figure 1 , Figure 2 and Figure 4As shown, the folding leg mechanism 4 includes a rotating connecting block 41. The first rear table leg 3, the second rear table leg 31, and the front table leg 32 all have sliding grooves 42 in the middle. The rotating connecting block 41 is slidably connected to the two sliding grooves 42 on the same side. The rotating connecting block 41 is tightly fitted with the sliding groove 42. The rotating connecting block 41 is rotatably connected to the inner table leg 33. The rotating connecting block 41 and the sliding groove 42 make the second rear table leg 31 and the front table leg 32 on the same side triangularly intersect. The first rear table leg 3 and the front table leg 32 on the same side are also triangularly intersected. The triangle has stability, making the desk more stable.

[0035] like Figure 2 , Figure 5 and Figure 6 As shown, the buckle mechanism 5 includes a clamping buckle 51 and a first spring 52. The clamping buckle 51 is slidably connected to the middle of the rear side of the desk 1, and the first spring 52 is connected to both the left and right sides between the clamping buckle 51 and the desk 1.

[0036] When a school needs to purchase a batch of desks, the desks need to be moved onto a transport vehicle. This requires folding the desk legs. First, hold the second rear leg 31 and the front leg 32, and apply upward force. This causes the rotating connecting block 41 to slide within the sliding groove 42, rotating the second rear leg 31 and the front leg 32 until they are horizontal. During this folding process, the rotating connecting block 41 can slide and fold the right inner leg 33 inward, thus folding the right side of the desk. Then, hold the first rear leg 3 and the front leg 32, and apply upward force. This causes the rotating connecting block 41 to slide within the sliding groove 42, rotating the first rear leg 3 and the front leg 32 until they are horizontal. During this folding process, the rotating connecting block 41 can slide and fold the inner leg 33 upward, thus folding the left side of the desk. This is very... Convenient for transportation, small in size, and requires no manpower to remove bolts. After the table legs are folded, the clamping buckle 51 can be pulled back, stretching the first spring 52. Then, the rope can be threaded through the clamping buckle 51, and then the clamping buckle 51 can be released. Under the elastic force, the first spring 52 drives the clamping buckle 51 to reset, thus clamping the rope. This allows all the desks in the transport vehicle to be tied together, and then the tied desks can be tied to the fixed objects of the transport vehicle, thus preventing the desks from moving during transportation and fixing their position, preventing damage. In summary, the folding leg mechanism 4 can easily fold the two sides of the table legs without requiring manpower to remove bolts, reducing the area occupied by the desks in the transport vehicle. The buckle mechanism 5 can also fix the desks in the transport vehicle, preventing them from moving and thus avoiding damage. When the desks need to be used normally, the folded parts can be opened.

[0037] Example 2

[0038] Based on Example 1, such as 1, Figure 2 and Figure 7 As shown, it also includes a folding mechanism 6, which includes folding rods 61, rotating pins 62, and ordinary hinges 63. The middle of the left and right sides of the desktop 1 is rotatably connected to two folding rods 61 through rotating pins 62. The middle of the left and right sides of the drawer 2 is also rotatably connected to two folding rods 61 through rotating pins 62. Ordinary hinges 63 are connected between the two folding rods 61 in the same vertical direction.

[0039] After folding the table legs, people push the front hinge 63 forward and the rear hinge 63 backward, causing the front folding rod 61 to fold together and the rear folding rod 61 to fold together. The folding rod 61 will cause the drawer front 2 to fold upward and closer to the desktop 1. The upward movement of the drawer front 2 will cause the drawer support frame 21 to move upward and out of the desktop 1. At this time, the torsion spring hinge 22, which is in a deformed state, will return to its original position and cause the drawer support frame 21 to fold forward onto the desktop 1. In this way, the drawer front 2 and the desktop 1 are folded together perfectly, saving space. When it is necessary to unfold, people rotate the drawer support frame 21 backward and then push the drawer support frame 21 downward to the desktop 1. The drawer support frame 21 pushes the drawer front 2 downward to unfold, and the folding rod 61 also extends to provide support.

[0040] like Figure 2 and Figure 8 As shown, it also includes a protection mechanism 7, which includes a wedge block 71 and a second spring 72. The wedge block 71 is slidably connected to both sides of the middle rear side of the desktop 1. The second spring 72 is connected to both the wedge block 71 and the interior of the desktop 1. The clamping buckle 51 has slots on both sides of the front part. The slots and the wedge block 71 are engaged and fitted together. The clamping buckle 51 and the wedge block 71 are pressed together.

[0041] First, in the initial state, the first spring 52 is in its natural state. The clamping buckle 51 presses against the wedge block 71, compressing the second spring 72. Then, the clamping buckle 51 is pulled backward, stretching the first spring 52. Under the elastic force, the second spring 72 causes the wedge block 71 to engage in the slot, thus fixing the clamping buckle 51. The rope can then be threaded through the clamping buckle 51, preventing the first spring 52 from exceeding its elastic limit due to the rope's tension during transport, thus avoiding damage to the desk during transport.

[0042] like Figure 1 , Figure 2 and Figure 9 As shown, it also includes a locking mechanism 8, which includes a locking block 81 and a third spring 82. The upper part of the inner table leg 33 is slidably connected to two locking blocks 81, and the upper and lower sides between the two locking blocks 81 are connected to the third spring 82.

[0043] After the desks are transported to the school, the folded desk legs need to be extended so that the rotating connecting block 41 slides downward, thereby causing the inner desk leg 33 to automatically extend downward. This causes the locking block 81 to lock the inner desk leg 33, preventing the inner desk leg 33 from sliding downward due to gravity after items are placed on the desk, thus making the desk more stable.

[0044] like Figure 1 , Figure 10 and Figure 11 As shown, it also includes a connecting mechanism 9, which includes a connector 91 and a connecting torsion spring 92. The connector 91 is connected inside the second rear table leg 31, and the connecting torsion spring 92 is connected between the connector 91 and the second rear table leg 31. A special groove 93 is opened at the horizontal position of the first rear table leg 3 and the connector 91, and the special groove 93 fits the shape of the connector 91.

[0045] When transporting desks, first fold the desks. Then rotate the connector 91 to twist the connecting torsion spring 92. Align the connector 91 with the special groove 93 and then release the connector 91. Under the action of the connecting torsion spring 92, the connector 91 will be locked in the special groove 93, thus connecting the two desks together. This reduces the area occupied and saves transportation costs.

[0046] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
