Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a reading table corner connector capable of stable connection. Background Art

[0002] Most reading tables are used in places such as libraries and reading rooms. During the use of reading tables, it is often necessary to assemble multiple tables into a whole. When assembling the tabletop, connectors are required.

[0003] The patent with the patent authorization announcement number CN212838821U discloses a table corner connector. The table corner connector includes a connector body and a connecting piece. At least two threaded holes are provided on the connector body. The two threaded holes are respectively used to connect the table legs and the tabletop. A first connecting head is provided on the connector body. The first connecting head is connected to the connecting piece, and the connecting piece is connected to the cross beam of the table. And there is an included angle between adjacent connecting pieces. This table corner connector relies on cooperation with bolts to achieve the purpose of assembling multiple tables. When using this device, holes matching the bolts need to be reserved on the tabletop, resulting in limited application range of this table corner connector, and it is relatively inconvenient to install and disassemble relying on bolts.

[0004] Therefore, we propose a reading table corner connector capable of stable connection that can be quickly disassembled and assembled and can be applied to different tabletops. Summary of the Invention

[0005] In order to overcome the disadvantages that the existing table corner connectors need to reserve holes during use and the installation and disassembly are relatively cumbersome, the present invention provides a reading table corner connector capable of stable connection that can be quickly disassembled and assembled and can be applied to different tabletops.

[0006] A reading table corner connector capable of stable connection includes a lower clamping plate, a guide rod, a sliding rod, an upper clamping plate and a clamping mechanism. A guide rod is connected to the middle position of the front side of the lower clamping plate. A sliding rod is slidably connected inside the guide rod. The upper end of the sliding rod is connected to the upper clamping plate. A clamping mechanism is provided between the lower clamping plate and the upper clamping plate. The clamping mechanism is used to adjust the distance between the lower clamping plate and the upper clamping plate to clamp and connect tabletops of different thicknesses.

[0007] As a further preferred solution, the left and right parts of the lower clamping plate and the upper clamping plate are both rotatably connected.

[0008] As a further preferred solution, the clamping mechanism includes a lower mounting block, an upper mounting block and a lead screw. The front positions of the left and right parts of the lower clamping plate are both connected with a lower mounting block. The front positions of the left and right parts of the upper clamping plate are both connected with an upper mounting block. The upper mounting blocks are all slidably connected to the adjacent lower mounting blocks. The lead screws are rotatably connected to the lower mounting blocks, and the lead screws are threadedly connected to the adjacent upper mounting blocks. When the lead screws rotate, the upper mounting blocks slide up and down, and the upper clamping plate moves up and down accordingly to cooperate with the lower clamping plate to clamp the tabletop.

[0009] As a further preferred solution, it further includes a fixing mechanism for fixing the upper clamping plate on the tabletop. The fixing mechanism includes a first rotating plate, a cylinder, a piston rod, a suction cup and a first spring. The left and right parts of the front side of the upper clamping plate are both rotatably connected with a first rotating plate. The rear parts of the first rotating plates are both connected with a cylinder. The piston rods are all slidably connected in the cylinders. The suction cups are connected to the lower sides of the cylinders. A first spring is connected between the piston rod and the adjacent cylinder. After the suction cup sucks on the tabletop, the piston rod slides upward to suck out the air in the suction cup.

[0010] As a further preferred solution, it further includes a rotating mechanism for restricting the position of the piston rod. The rotating mechanism includes a second rotating plate and a cross bar. The upper parts of the piston rods are all rotatably connected with a second rotating plate. The lower ends of the second rotating plates are all in contact with the adjacent first rotating plate. The piston rod is supported and limited by the vertically placed second rotating plate. At this time, the piston rod is in the state after moving upward. Cross bars are connected to the upper parts of the second rotating plates.

[0011] As a further preferred solution, it further includes a clamping mechanism for clamping the left and right parts of the lower clamping plate. The clamping mechanism includes a guide rod, a clamping block and a second spring. The right part of the lower side of the left half of the lower clamping plate is connected with a guide rod. A clamping block is slidably connected to the guide rod. The upper end of the clamping block is inserted into the right half of the lower clamping plate. A second spring is connected between the clamping block and the guide rod.

[0012] As a further preferred solution, it further includes a pushing mechanism for automatically rotating the second rotating plate. The pushing mechanism includes a first guiding block, a pushing plate and an L-shaped rod. The right part of the upper clamping plate is connected with a first guiding block. The pushing plate is slidably connected to the upper part of the first guiding block. The ends of the cross bars are all located on the front side of the upper part of the pushing plate. The L-shaped rod is connected to the front side of the clamping block. The upper ends of the L-shaped rods are all in contact with the front part of the pushing plate. When the L-shaped rod moves upward, it squeezes the pushing plate to slide forward. The pushing plate slides forward to drive the second rotating plate to rotate into a vertical state through the cross bar.

[0013] As a further preferred solution, it further includes a limiting mechanism for clamping the first rotating plate. The limiting mechanism includes a second guiding block, a limiting block, a third spring, and a pushing rod. The front positions of the left and right parts of the upper clamping plate are both connected with a second guiding block. The limiting blocks are slidably connected in the second guiding blocks. The limiting blocks slide forward and are respectively clamped into the adjacent first rotating plates to fix the positions of the first rotating plates. A third spring is connected between each limiting block and the adjacent second guiding block. The rear ends of the limiting blocks are both connected with a pushing rod, and the pushing rods are both connected with the pushing plate.

[0014] The present invention has the following advantages: 1. The left and right parts of the lower clamping plate and the upper clamping plate can be rotated and separated, which is convenient for moving and splicing two tables. After the two table boards are aligned, the right parts of the lower clamping plate and the upper clamping plate rotate backward and reset. By cooperating the lead screw with the upper mounting block, the upper clamping plate is controlled to move downward to cooperate with the lower clamping plate to clamp the two table boards. Since the device is assembled and connected by means of clamping and fixing, it can be quickly installed and disassembled, and can also adapt to table boards of different thicknesses.

[0015] 2. After the lower clamping plate and the upper clamping plate clamp the two table boards, the suction cups are adsorbed on the table boards to further connect the two table boards. And the upward sliding of the piston rod can make the lower part of the cylinder in a vacuum state, so that the suction cups are adsorbed more firmly, and the two table boards are also connected more firmly.

[0016] 3. The forward swing of the second rotating plate drives the piston rod to slide upward by using the lever principle. When the second rotating plate rotates to a vertical state, the lower end of the second rotating plate contacts the first rotating plate to limit the position of the piston rod. In this way, it is more convenient for the staff to control the upward sliding of the piston rod, and at the same time, the position of the piston rod can be fixed.

[0017] 4. After the device is sleeved on the connection part of the two table boards, the clamping block slides upward and is clamped into the right half of the lower clamping plate, thereby fixing the left and right parts of the lower clamping plate and preventing rotation after the table boards are assembled.

[0018] 5. The upward sliding of the clamping block can cooperate with the pushing plate through the L-shaped rod to simultaneously control the cross bars of the left and right parts to swing forward, and then simultaneously control the piston rods of the left and right parts to slide upward for air suction, so that the suction cups are adsorbed more firmly.

[0019] 6. When the pushing plate is extruded and slides forward, it will also drive the pushing rod to move forward, and then drive the limiting block to slide forward and be clamped into the first rotating plate to fix the first rotating plate and prevent the first rotating plate from rotating after the table is assembled.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] A reading table corner connector capable of stable connection, as Figures 1-4As shown in the figure, it includes a lower clamping plate 1, a guide rod 2, a sliding rod 3, an upper clamping plate 4, a clamping mechanism 5 and a fixing mechanism 6. A guide rod 2 is connected to the middle position of the front side of the lower clamping plate 1. A sliding rod 3 is slidably connected inside the guide rod 2. The upper end of the sliding rod 3 is connected to the upper clamping plate 4. The left and right parts of the lower clamping plate 1 and the upper clamping plate 4 are both rotatably connected. A clamping mechanism 5 is provided between the lower clamping plate 1 and the upper clamping plate 4. The clamping mechanism 5 can adjust the distance between the lower clamping plate 1 and the upper clamping plate 4 to clamp and connect table boards of different thicknesses. A fixing mechanism 6 is provided on the upper clamping plate 4. The fixing mechanism 6 can fix the upper clamping plate 4 on the table board.

[0034] When using this device, the staff rotates the right parts of the lower clamping plate 1 and the upper clamping plate 4 forward. Then the staff slews the left halves of the lower clamping plate 1 and the upper clamping plate 4 around the table corner, making the right sides of the left halves of the lower clamping plate 1 and the upper clamping plate 4 flush with the right side of the table board. When another table board moves to be spliced with this table board, the staff pushes the right parts of the lower clamping plate 1 and the upper clamping plate 4 backward to rotate and reset, so that the left halves of the lower clamping plate 1 and the upper clamping plate 4 are slewed on the other table board. At this time, the staff can control the upper clamping plate 4 to move downward through the clamping mechanism 5. After the upper clamping plate 4 moves downward, it cooperates with the lower clamping plate 1 to clamp the two table boards, and then the two tables are assembled together. And the fixing mechanism 6 can adsorb on the two table boards to ensure that this device stably connects the two tables together.

[0035] As Figure 1 and Figure 2 shown, the clamping mechanism 5 includes a lower mounting block 51, an upper mounting block 52 and a lead screw 53. The front parts of the left and right parts of the lower clamping plate 1 are both bolted with the lower mounting block 51. The front parts of the left and right parts of the upper clamping plate 4 are both bolted with the upper mounting block 52. The upper mounting blocks 52 are both slidably connected to the adjacent lower mounting blocks 51. Lead screws 53 are rotatably connected to the lower mounting blocks 51. The lead screws 53 are both threadedly connected to the adjacent upper mounting blocks 52.

[0036] When using this device, the staff rotates the lead screw 53. The rotation of the lead screw 53 drives the upper mounting block 52 to slide upward. The upward sliding of the upper mounting block 52 drives the upper clamping plate 4 to move upward to adjust the gap between the upper clamping plate 4 and the lower clamping plate 1 to adapt to table boards of different thicknesses. After this device is slewed around the connection of the two tables, the staff reversely rotates the lead screw 53. The reverse rotation of the lead screw 53 drives the upper mounting block 52 to slide downward. The downward sliding of the upper mounting block 52 drives the upper clamping plate 4 to move downward. The downward movement of the upper clamping plate 4 cooperates with the lower clamping plate 1 to clamp the table board, and then the two table boards are assembled and connected together. When it is necessary to disassemble this device, the staff directly rotates the lead screw 53 to control the upper clamping plate 4 to move upward, and then pulls this device out of the table board. In this way, quick disassembly and assembly can be carried out, and it can also adapt to table boards of different thicknesses.

[0037] As Figure 1 、Figure 3 and Figure 4 As shown in Figure 4 , the fixing mechanism 6 includes a first rotating plate 61, a cylinder 62, a piston rod 63, a suction cup 64 and a first spring 65. The left and right parts on the front side of the upper clamping plate 4 are both rotatably connected with the first rotating plates 61. The rear parts of the first rotating plates 61 are both welded with cylinders 62. The piston rods 63 are both slidably connected in the cylinders 62. The suction cups 64 are both connected to the lower sides of the cylinders 62. A first spring 65 is connected between the piston rod 63 and the adjacent cylinder 62.

[0038] When using the device, the staff pushes the first rotating plate 61 to rotate forward. The first rotating plate 61 drives the suction cup 64 to move forward through the cylinder 62 and be misaligned with the tabletop, avoiding the suction cup 64 sucking on the tabletop and affecting the movement of the tabletop when splicing and finely adjusting the tabletop. When the two tables are aligned, the staff pushes the first rotating plate 61 to rotate backward, and then drives the suction cup 64 to rotate backward and reset through the cylinder 62. When the upper clamping plate 4 moves downward, the first rotating plate 61 drives the suction cup 64 to move downward and suck on the tabletop through the cylinder 62. After the suction cup 64 sucks on the tabletop, the staff can pull the piston rod 63 to slide upward and fix it. The first spring 65 deforms. The upward sliding of the piston rod 63 makes the lower part of the cylinder 62 in a vacuum state, making the suction cup 64 adsorb more firmly. The suction cup 64 sucking on the tabletop can further connect the two tabletops and make their connection more stable. When the device needs to be disassembled, the staff loosens the piston rod 63. Under the action of the reset of the first spring 65, the piston rod 63 slides downward and resets accordingly. At this time, the suction cup 64 can be easily pulled off the tabletop.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, as Figure 1 and Figure 5 shown, it further includes a rotating mechanism 7. The rotating mechanism 7 can limit the position of the piston rod 63. The rotating mechanism 7 includes a second rotating plate 71 and a cross bar 72. The upper parts of the piston rods 63 are both rotatably connected with the second rotating plates 71. The lower ends of the second rotating plates 71 are both in contact with the adjacent first rotating plates 61. The piston rod 63 is supported and limited by the vertically arranged second rotating plate 71. At this time, the piston rod 63 is in the state after moving upward. Cross bars 72 are both welded to the upper parts of the second rotating plates 71.

[0041] When using this device, the staff member pushes the crossbar 72 to swing backward. The backward swing of the crossbar 72 drives the second rotating plate 71 to rotate backward. At this time, the lower end of the second rotating plate 71 no longer presses against the first rotating plate 61, and the piston rod 63 can then slide downward. After the suction cup 64 adsorbs on the tabletop, the staff member pushes the crossbar 72 to swing forward, and the second rotating plate 71 rotates forward accordingly. At this time, the lower end of the second rotating plate 71 presses against the first rotating plate 61, driving the piston rod 63 to slide upward by using the lever principle. When the second rotating plate 71 rotates to a vertical state, the lower end of the second rotating plate 71 contacts the first rotating plate 61, thereby restricting the position of the piston rod 63. In this way, it is more convenient for the staff member to control the upward sliding and inhalation of the piston rod 63, and at the same time, the position of the piston rod 63 can be fixed.

[0042] As Figure 1 and Figure 6 shown, it further includes a clamping mechanism 8. The clamping mechanism 8 can clamp the left and right parts of the lower clamping plate 1. The clamping mechanism 8 includes a guide rod 81, a clamping block 82, and a second spring 83. A guide rod 81 is welded to the lower right part of the left half of the lower clamping plate 1. A clamping block 82 is slidably connected to the guide rod 81. The upper end of the clamping block 82 is inserted into the right half of the lower clamping plate 1. A second spring 83 is connected between the clamping block 82 and the guide rod 81.

[0043] When using this device, before splicing the tables, the staff member pushes the clamping block 82 to slide downward on the guide rod 81, and the second spring 83 deforms. After the clamping block 82 slides downward, it no longer clamps the right half of the lower clamping plate 1. At this time, the right half of the lower clamping plate 1 can rotate forward and open, facilitating the splicing of another table. When the right half of the lower clamping plate 1 rotates backward and is reset to sleeve on another tabletop, the staff member releases the clamping block 82. Under the action of the reset of the second spring 83, the clamping block 82 slides upward and is reset to be inserted into the right half of the lower clamping plate 1, thereby fixing the left and right parts of the lower clamping plate 1 and preventing rotation after the tabletop is assembled.

[0044] As Figure 1 and Figure 7 shown, it further includes a pushing mechanism 9. The pushing mechanism 9 can automatically rotate the second rotating plate 71. The pushing mechanism 9 includes a first guide block 91, a pushing plate 92, and an L-shaped rod 93. A first guide block 91 is welded to the right part of the upper clamping plate 4. A pushing plate 92 is slidably connected to the upper part of the first guide block 91. The front lower side of the pushing plate 92 is inclined. The tails of the crossbars 72 are all located in front of the upper part of the pushing plate 92. An L-shaped rod 93 is welded to the front side of the clamping block 82, and the upper ends of the L-shaped rods 93 are all in contact with the front part of the pushing plate 92.

[0045] When using the device, the clamping block 82 slides downward to drive the L-shaped rod 93 to move downward. After the device is fixed between two table boards, the clamping block 82 slides upward to drive the L-shaped rod 93 to move upward. The upward movement of the L-shaped rod 93 squeezes the push plate 92 to slide forward. While the push plate 92 slides forward, it pushes the cross bars 72 on the left and right sides to swing forward, thereby simultaneously controlling the piston rods 63 on the left and right sides to slide upward for air suction, making the suction cups 64 adsorb more firmly.

[0046] As Figure 1 , Figure 8 , Figure 9 and Figure 10 shown, it further includes a limiting mechanism 10. The limiting mechanism 10 can clamp the first rotating plate 61. The limiting mechanism 10 includes a second guiding block 101, a limiting block 102, a third spring 103 and a push rod 104. The front positions of the left and right sides of the upper clamping plate 4 are both welded with a second guiding block 101. The second guiding blocks 101 are both connected with a limiting block 102 in a sliding manner. A third spring 103 is connected between the limiting block 102 and the adjacent second guiding block 101. The rear ends of the limiting blocks 102 are both welded with a push rod 104, and the push rods 104 are both connected with the push plate 92.

[0047] When using the device, when the push plate 92 is squeezed to slide forward, it will also drive the push rod 104 to move forward. The forward movement of the push rod 104 drives the limiting block 102 to slide forward in the second guiding block 101, and the third spring 103 deforms. After the limiting block 102 slides forward, it is clamped into the first rotating plate 61, thereby fixing the first rotating plate 61 and preventing the first rotating plate 61 from rotating after the table is assembled. When the L-shaped rod 93 moves downward and no longer squeezes the push plate 92, under the action of the reset of the third spring 103, the limiting block 102 slides backward to release the first rotating plate 61. While the limiting block 102 slides backward, it drives the push plate 92 to slide backward and reset through the push rod 104. In this way, the first rotating plate 61 can be fixed to prevent the first rotating plate 61 from rotating after the table is assembled.

[0048] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
