Description

Technical Field

[0001] This application relates to the technical field of table mounting, and more specifically, to a table mounting fixture. Background Technology

[0002] Existing conference tables, office desks, etc., have a structure that includes multiple crossbeams to support the tabletop. These crossbeams work together to form a tabletop support frame. Table legs are installed at the angle formed by two adjacent crossbeams, and then the tabletop is fixed to the upper part of the crossbeams to complete the assembly.

[0003] However, in the above-mentioned multi-beam tabletop support frame structure, it is difficult for adjacent beams to form a precise angle between each other during the assembly process. If one of the angles is not assembled accurately, it will affect the formation of the remaining angles, making it difficult or impossible to assemble the tabletop support frame smoothly. Therefore, a tooling structure is needed to precisely define the angle between adjacent beams in order to achieve the smooth assembly of the tabletop support frame. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, this application provides a table assembly fixture that can accurately adjust and limit the included angle between two adjacent crossbeams of the support frame, thereby ensuring the smooth assembly of the support frame.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a table installation fixture, wherein the table includes a tabletop and multiple crossbeams and a fixed corner bracket installed at the lower end of the tabletop; the table installation fixture includes an angle limiting structure and an abutment structure, the angle limiting structure is provided with a fixing position and a mounting plate, each pair of adjacent crossbeams is placed at the fixing position, the abutment structure is located on the mounting plate, the fixed corner bracket is located between two adjacent crossbeams, and the abutment structure is used to push the fixed corner bracket so that the fixed corner bracket drives the two adjacent crossbeams to fit against the corresponding angle limiting structure.

[0006] By employing the aforementioned structure, this application utilizes a table installation fixture to precisely adjust and limit the angle between adjacent table frame support beams, thereby ensuring consistency in the angles of multiple beams and facilitating the formation of a complete tabletop support frame. Furthermore, this fixture eliminates the need for complex installation operations. Simply place the fixture on the underside of the tabletop, abut the two adjacent beams requiring adjustment against the fixture's angle-limiting structure, install the fixing bracket, and then push the fixing bracket against the abutment structure to correct and limit the angle and position of the two beams. This achieves a precise angle between the two beams. Connecting the fixing bracket to the tabletop further positions the angle. Finally, removing the fixture allows for precise adjustment and positioning of the beam angles. Therefore, the operation is convenient, the adjustment is accurate, and the entire tabletop support frame can be assembled smoothly.

[0007] Furthermore, the included angle limiting structure includes a first included angle arm and a second included angle arm, the adjacent ends of which are connected to each other to form an included angle for adjustment of two adjacent crossbeams; with this structure, one crossbeam is fitted with the inner wall of the first included angle arm, and the other crossbeam is fitted with the inner wall of the second included angle arm, thereby precisely limiting the included angle between the two adjacent crossbeams and achieving precise adjustment of the included angle between the two crossbeams.

[0008] Furthermore, a foot support block is provided between the first and second angled arms. The foot support block is used to abut against the adjacent ends of two adjacent crossbeams, so that a foot groove is formed between the adjacent ends of the two adjacent crossbeams. With this structure, after the position and angle of the two crossbeams are fixed, a connection is formed between the fixed corner bracket and the table. After the tooling is removed, the mounting position for the table legs is formed between the adjacent ends of the two crossbeams, i.e., the original position occupied by the foot support block. Moreover, this structure can ensure the consistency of the specifications of the foot grooves formed at multiple angled positions, which facilitates the subsequent installation of the table legs.

[0009] Furthermore, a clearance groove is provided on the surface of the mounting plate near the crossbeam. With this structure, when the table mounting fixture of this application is placed in the correction position of the table, the clearance groove ensures that the mounting plate does not contact the crossbeam, preventing the table mounting fixture from being lifted by the crossbeam. This allows it to fit fully against the table, ensuring the accuracy of the fixture in correcting the angle between the two crossbeams.

[0010] Furthermore, multiple pads are provided on the inner walls of the first and second included-angle arms, and the pads are used to abut against the outer walls of the two adjacent crossbeams; this structure can avoid wear or damage caused by hard contact between the crossbeams and the included-angle limiting structure.

[0011] Furthermore, each end of the fixed corner frame is provided with a plug-in part, and the inner walls of the two crossbeams are provided with corresponding insertion holes. The plug-in parts are used to plug into the insertion holes and can move along the width extension direction of the insertion holes. With this structure, the fixed corner frame and the two crossbeams can be connected by plugging the plug-in parts into the insertion holes. Then, under the pushing action of the abutment structure, the fixed corner frame is driven to move along the width extension direction of the insertion holes, so that the two crossbeams are tightly fitted with the angle limiting structure, realizing the precise correction and adjustment of the angle between the two crossbeams. After the adjustment is completed, the fixed corner frame can be connected to the table, realizing the positioning of the angle between the two crossbeams.

[0012] Furthermore, the abutment structure includes a base connected to the mounting plate, a drive handle on the base, a connecting rod connected to one end of the drive handle, and an abutment joint on the inner end of the connecting rod. The drive handle is used to drive the connecting rod to push the abutment joint against the fixed angle bracket. With this structure, the connecting rod is extended or retracted by rotating the drive handle, thereby enabling the abutment joint to push against the fixed angle bracket to correct and position the included angle of two adjacent crossbeams.

[0013] Furthermore, the mounting plate and the fixed corner bracket are arranged parallel to each other. With this structure, the abutment structure located on the mounting plate can smoothly push the fixed corner bracket to correct and limit the angle between the two crossbeams.

[0027] As attached Figure 1-10As shown, this application discloses a table installation fixture, wherein the table includes a tabletop 1 and multiple crossbeams 2 and a fixed corner bracket 3 installed at the lower end of the tabletop 1; the table installation fixture includes an angle limiting structure 4 and an abutment structure 5, the angle limiting structure 4 is provided with a fixing position and a mounting plate 6, each pair of adjacent crossbeams 2 is placed at the fixing position, the abutment structure 5 is located on the mounting plate 6, and the fixed corner bracket 3 is located between two adjacent crossbeams 2, the abutment structure 5 is used to push the fixed corner bracket 3 so that the fixed corner bracket 3 drives the two adjacent crossbeams 2 to fit against the corresponding angle limiting structure 4; specifically, as shown in the attached figure. Figure 4-6 As shown, the table installation fixture of this application is set at each of the multiple angles formed by the multiple crossbeams 2, i.e., the aforementioned fixed positions. The angle limiting structure 4 has a fixed angle, and the abutment structure 5 pushes the fixed corner bracket 3 to drive the two adjacent crossbeams 2 to fit tightly against it, thereby adjusting and correcting the angle between the two adjacent crossbeams 2. After adjustment, the fixed corner bracket 3 at this position is fixedly connected to the tabletop 1. Specifically, as shown in the attached... Figure 8 As shown, mounting holes are provided in the fixed corner bracket 3 along its thickness direction. Screws, bolts and other connecting parts can be screwed into the mounting holes to fix it to the tabletop 1, thereby limiting the included angle between the two adjacent crossbeams 2 and realizing the adjustment and positioning of the included angle.

[0028] By adopting the above structure, this application uses this table installation fixture to achieve precise adjustment and positioning of the included angle between two adjacent crossbeams 2, thereby enabling the consistency of multiple included angles of the crossbeams 2 of the table frame, facilitating the formation of a complete tabletop support frame. In addition, this fixture does not require complicated installation operations. It is only necessary to place the fixture on the bottom surface of the tabletop 1, abut the two adjacent crossbeams 2 that need to be adjusted against the included angle positioning structure 4 of the fixture, install the fixed corner bracket 3, and then push the fixed corner bracket 3 through the abutment structure 5 to correct and limit the angle and position of the two crossbeams 2, thereby achieving the precise formation of the included angle between the two crossbeams 2. Then, the fixed corner bracket 3 is connected to the tabletop 1 to position the included angle. Finally, after removing the fixture, the precise adjustment and positioning of the included angle of the crossbeams 2 can be achieved. Therefore, the operation is convenient, the adjustment is accurate, and the entire tabletop support frame can be assembled smoothly and completely.

[0029] As attached Figure 1-6As shown, the included angle limiting structure 4 of this application includes a first included angle arm 401 and a second included angle arm 402. The adjacent ends of the first included angle arm 401 and the second included angle arm 402 are connected to each other to form an included angle for adjustment of two adjacent crossbeams 2. One of the two adjacent crossbeams 2 is fitted with the inner wall of the first included angle arm 401, and the other crossbeam 2 is fitted with the inner wall of the second included angle arm 402, thereby precisely limiting and adjusting the included angle between the two crossbeams 2, and realizing precise adjustment of the included angle between the two crossbeams 2. As an example, see attached... Figure 4-6 As shown, the table in this application example has four table legs, which are connected in sequence to form a rectangle. Four sets of table installation fixtures of the same specifications are used to adjust and correct the four 90° angles of the support frame formed by the four crossbeams 2, thereby ensuring the consistency of the four angles and successfully completing the assembly of the overall support frame.

[0030] As attached Figure 1-6 As shown, a foot support block 7 is provided between the first included arm 401 and the second included arm 402 described in this application. The foot support block 7 is used to abut against the adjacent ends of two adjacent crossbeams 2 so that a foot locking groove 8 is formed between the adjacent ends of the two adjacent crossbeams 2. Specifically, the aforementioned foot slot 8 is adapted to the table leg structure of the tabletop 1, and the table leg is installed in the foot slot 8 to support the tabletop 1. With the setting of the foot support block 7, after the position and angle of the two adjacent crossbeams 2 are fixed, a fixed connection is formed between the fixed corner bracket 3 and the tabletop 1. After removing the tooling of this application, the foot slot 8 for installing the table legs is formed between the adjacent ends of the two crossbeams 2, i.e., the original position occupied by the foot support block 7. Moreover, this structure can ensure the consistency of the specifications of the foot slots 8 formed at multiple angle positions, which is convenient for the subsequent installation of the table legs. The foot support block 7 here can be integrally formed with the first angle arm 401 and the second angle arm 402 to form a more robust angle limiting structure 4.

[0031] As attached Figure 3 and attached Figure 10 As shown, the mounting plate 6 of this application has a relief groove 601 on the surface near the crossbeam 2. The relief groove 601 extends in a direction away from the crossbeam 2. When the fixture is placed on the bottom surface of the tabletop 1, the relief groove 601 is aligned with the crossbeam 2 in the vertical direction and there is a gap between them. With this structure, when the table mounting fixture of this application is placed in the correction position of the tabletop 1, the relief groove 601 can prevent the mounting plate 6 from contacting the crossbeam 2, so that the table mounting fixture will not be lifted by the crossbeam 2, and thus it can fit fully with the tabletop 1, ensuring the accuracy of the fixture in correcting the angle between the two crossbeams 2.

[0032] As an example, the included angle formed between the first included arm 401 and the second included arm 402 described in this application is a right angle, that is, the included angle of the included angle limiting structure 4 is a 90-degree right angle structure. Therefore, when two adjacent crossbeams 2 are fitted and adjusted to fit with it, they also form a right angle with each other, as shown in the attached figure. Figure 4-6 As shown, all four included angles of the support frame are right angles; this structure can be adapted to the assembly of support frames that are assembled with right angles on the market, making it highly adaptable and easy to adjust and correct.

[0033] As an example, the extension lengths of the first included arm 401 and the second included arm 402 described in this application are equal, that is, they are set to be of equal length. With this structure, when the fixed corner bracket 3 pushes the two adjacent crossbeams 2 to perform position correction and adjustment, the first included arm 401 and the second included arm 402 can achieve balanced contact and limit on the two crossbeams 2, forming a more precise angle adjustment between the two crossbeams 2.

[0034] As attached Figure 1-4 As shown, the two ends of the mounting plate 6 in the length direction of this application are respectively connected to the bottom surface of one side of the first included angle arm 401 and the second included angle arm 402 in the thickness direction. Specifically, the mounting plate 6 is connected to the bottom surface of the first included angle arm 401 and the second included angle arm 402 away from the table 1. That is, the table 1 and the mounting plate 6 are respectively located on opposite sides of the included angle limiting structure 4 in the thickness direction. At this time, the first included angle arm 401, the second included angle arm 402 and the mounting plate 6 form a stable isosceles triangle structure to maintain the stability of the structure during the use of the tooling, so as to form a more precise included angle adjustment between the two crossbeams 2. Moreover, by setting the mounting plate 6 on the side away from the table 1, when the tooling is finished, it can be directly removed from the bottom surface of the table 1, that is, the side where the crossbeams 2 are set, without any obstruction, making disassembly convenient.

[0035] As attached Figure 1-3 As shown, the inner walls of the first included arm 401 and the second included arm 402 described in this application are each provided with a plurality of pads 403. The pads 403 are used to abut against the outer walls of the two adjacent crossbeams 2. With this structure, specifically, the pads 403 can be made of flexible material, thereby avoiding wear or damage caused by hard contact between the crossbeams 2 and the included angle limiting structure 4.

[0036] As attached Figure 7-8As shown, the fixed corner bracket 3 of this application is provided with insertion parts 301 at both ends, and corresponding insertion holes 201 are provided on the inner walls of the two adjacent crossbeams 2. The insertion parts 301 are used to insert into the insertion holes 201 and can move along the width extension direction of the insertion holes 201. That is, the insertion holes 201 have a certain extension width along the length direction of the crossbeam 2. After the insertion parts 301 are inserted into the insertion holes 201, under the pushing action of the abutment structure 5, they can move along the width direction of the insertion holes 201 to push the crossbeam 2 to the clamp. The corner limiting structure 4 fits tightly; specifically, the fixed corner bracket 3 is connected to the two crossbeams 2 by inserting the plug 301 into the plug hole 201. Then, under the pushing action of the abutment structure 5, the fixed corner bracket 3 is driven to move along the width extension direction of the plug hole 201, so that the two crossbeams 2 fit tightly with the included angle limiting structure 4, thereby correcting and adjusting the included angle between the two crossbeams 2. After the adjustment is completed, the fixed corner bracket 3 and the table board 1 can be fixedly connected to each other, thereby positioning the included angle between the two crossbeams 2.

[0037] As attached Figure 1 and Figure 3 and Figure 9 As shown, the abutment structure 5 of this application includes a base 501 connected to the mounting plate 6. A drive handle 502 is provided on the base 501. A connecting rod 503 is provided at one end of the drive handle 502. An abutment joint 504 is provided at the inner end of the connecting rod 503. The drive handle 502 is used to drive the connecting rod 503 to push the abutment joint 504 against the fixed angle bracket 3. With this structure, the rotation of the drive handle 502 drives the connecting rod 503 to extend and retract, thereby allowing the abutment joint 504 to push the fixed angle bracket 3 for correction and positioning. Specifically, a crank 505 is also provided between the drive handle 502 and the connecting rod 503. The crank 505 has… The crank 505 has a bent structure. One end of the crank 505 is rotatably connected to the connecting rod 503, and the other end is rotatably connected to one side of the drive handle 502 extending in the length direction. The drive handle 502 is connected to the base 501 through a vertical rotating shaft 506. The connecting rod 503 can slide and fit into the support through hole extending upward in the base 501. When the drive handle 502 rotates around the vertical rotating shaft 506, it can realize the extension and retraction drive of the connecting rod 503 in the support through hole. Then, through the abutment joint 504, it drives the fixed angle bracket 3 to push the two adjacent crossbeams 2 and the included angle limiting structure 4 to fit tightly together, thereby realizing the adjustment and correction of the included angle between the crossbeams 2.

[0038] As an example, the mounting plate 6 and the fixed corner bracket 3 described in this application are arranged parallel to each other, that is, they are parallel to the plane extension direction of the tabletop 1. With this structure, the abutment structure 5 located on the mounting plate 6 can smoothly push the fixed corner bracket 3 to correct and limit the angle between the two adjacent crossbeams 2, and the fixed corner bracket 3 is also arranged parallel to the tabletop 1 during the pushing process.

[0039] The working principle and process of the table installation fixture described in this application are as follows: First, place two crossbeams 2 at appropriate positions on the bottom surface of the tabletop 1. Then, insert the plug-in parts 301 at both ends of the fixed corner bracket 3 into the corresponding plug holes 201 of the two adjacent crossbeams 2. Next, install the table installation fixture of this application at the two adjacent crossbeams 2. The included angle limiting structure 4 is located on the outer side of the two crossbeams 2, specifically at the corner of the tabletop 1. The first included angle arm 401 and the second included angle arm 402 with fixed included angles abut against the outer side walls of the two crossbeams 2 at the corresponding positions. The specific setting position of the table installation fixture of this application can be referred to the appendix. Figure 4-6 As shown; then rotate the drive handle 502 on the abutment structure 5. The circumferential rotation of the drive handle 502 will push the crank 505. Through the crank 505 and the connecting rod 503, the abutment joint 504 will push the fixed corner frame 3 to make the two adjacent crossbeams 2 fit more tightly with the included angle limiting structure 4, and the near ends of the two crossbeams 2 abut with the tube foot support block 7, so as to accurately adjust the included angle between the two crossbeams 2; after the adjustment is completed, screws or bolts are screwed into the mounting holes on the fixed corner frame 3 to fix it to the table board 1, thereby limiting the included angle of the two crossbeams 2. Then take out the table installation fixture of this application, leaving the tube foot slot 8 in the position originally occupied by the tube foot support block 7; the other three The included angles are also limited and fixed using the above-mentioned process. The crossbeam 2 and the tabletop 1 can also be connected by setting mounting holes on the crossbeam 2 and tightening screws or bolts. Finally, the table legs of the tabletop 1 are assembled in the four foot slots 8 to complete the assembly of the entire table. It can be seen that the table assembly fixture of this application can effectively correct and limit the included angles between two adjacent crossbeams 2, so that the multiple included angles of the tabletop support frame can be accurately adjusted and can maintain their consistency, which is more conducive to the quick and smooth assembly of the entire tabletop support frame. In addition, by setting the foot support block 7, the foot slots 8 can be reserved, and the specifications of the foot slots 8 at multiple included angles can be adjusted to be consistent, which also facilitates the subsequent assembly of the table legs of the tabletop 1.
