Description

Technical Field

[0001] The utility model relates to the technical field of table frame connection structures, in particular to a connection structure of rectangular supporting legs of a table frame. Background Art

[0002] The table frame is the structure or frame part that supports the tabletop. Its main function is to provide support and stability to ensure that the entire table can bear the weight of the object and maintain balance. The table frame usually includes legs and beams or support structures connecting these legs. In the design of the table frame, the choice of materials and the design of the structure have an important impact on the appearance and performance of the table. Some table frame designs also take ergonomics into consideration to ensure comfort and convenience when using the table. In general, the table frame is the basic supporting structure of the table, and its role is to provide the stability and structural support required for the tabletop.

[0003] The rectangular support leg connection structure is a connection piece specially designed for rectangular table legs, one end of which is connected to the table leg and the other end is connected to the crossbeam, and the upper end of the crossbeam is connected to the table board. Therefore, the height of the table frame can be adjusted by using the rectangular support leg connection method.

[0004] The existing rectangular support legs of the table frame are connected by bolts to ensure the firmness of the connection. However, this connection method limits the height adjustment ability of the table frame. When sitting at a desk for a long time, the user may feel discomfort in the spine and need to stand up to relax, but because they cannot leave their work, they need to adjust the height of the table frame to meet the needs of standing and working. However, since the height of the table frame cannot be adjusted, it cannot meet the actual needs of users to change the height of the table at any time. This has caused great limitations on the practicality of the table frame. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the existing rectangular supporting legs of a table frame are connected by bolts, which limits the height adjustment ability of the table frame, resulting in the inability to adjust the height of the table frame during long-term work, and the actual needs of users to change the height of the table at any time cannot be met. A connection structure for the rectangular supporting legs of the table frame is provided.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a connection structure of a rectangular support leg of a table frame, comprising: a rectangular sleeve, a connecting groove is provided on one side of the rectangular sleeve, an extrusion block is movably connected to one side of the connecting groove, a groove is provided on the outer wall of the extrusion block, the groove is arranged in a ring array on the outer wall of the extrusion block, the outer wall of one side of the rectangular sleeve is fixedly connected to a limiting mechanism, the other side of the limiting mechanism is fixedly connected to a movable mechanism, the movable mechanism comprises a turntable, a card groove is provided on the outer wall of the turntable, a sliding groove is provided on the side wall of the turntable, a slider is slidably connected to one side of the sliding groove, a connecting rod is connected to one side of the slider, a sphere is fixedly connected to the other side of the connecting rod, and the inner outer wall of the turntable is fixedly connected to a limiting ring.

[0007] As a preferred embodiment, the limiting mechanism includes a connecting plate, a threaded groove is opened on the side wall of the connecting plate, a ring is fixedly connected to the lower end of the connecting plate, a connecting column is fixedly connected to the inner wall of the ring, a connecting bearing is fixedly connected to the other side of the connecting column, a connecting piece is fixedly connected to the upper end of the outer wall of one side of the ring, and a block is rotatably connected to the outer wall of one end of the connecting piece.

[0008] As a preferred embodiment, the connecting bearing includes a connecting block 1, a mounting groove is provided on one side of the connecting block 1, a round ball is provided on the inner wall of the mounting groove, a connecting block 2 is provided on the other side of the round ball, and the outer wall of the connecting block 1 is movably connected to a limiting sleeve.

[0009] As a preferred embodiment, an outer wall on one side of the connecting block 2 is fixedly connected to an outer wall on one side of the connecting groove.

[0010] As a preferred implementation, the outer wall on the other side of the connecting block is fixedly connected to the outer wall on one side of the turntable.

[0011] As a preferred implementation, the inner wall of the limiting sleeve is fixedly connected to the outer wall of one side of the connecting block 2.

[0012] As a preferred embodiment, the sphere is movably connected to a groove formed on the outer wall of the extrusion block.

[0013] As a preferred implementation, the clamping block is clamped with a clamping groove formed on the outer wall of the turntable.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] The utility model is designed to rotate the turntable so that the slider slides on the inner wall of the slide groove, and drives the slider to deviate at the angle of the slide groove, so that the ball can shrink or expand inward. The ball acts on the groove on the outer wall of the extrusion block to clamp the extrusion block, and then transmits the clamping force to the support leg to complete the fastening operation of the support leg. This design solves the problem that the existing rectangular support legs of the table frame are connected by bolts, which limits the height adjustment ability of the table frame. When working for a long time, the user can relieve spinal discomfort by adjusting the height of the table, thereby improving the practicality of the table frame;

[0016] By designing a connector on one side of the connecting plate and limiting the connection block on the outer wall of the connector, the sharp corner at one end of the block is connected to the corresponding slot to achieve the limit effect on the turntable. This design solves the rebound problem that may occur when the movable mechanism rotates, and ensures the continuous tightening of the support legs. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] like Figure 1-6 As shown, the utility model provides a technical solution: a connection structure of a rectangular support leg of a table frame, comprising: a rectangular sleeve 1, a connection groove 2 is provided on one side of the rectangular sleeve 1, an extrusion block 3 is movably connected to one side of the connection groove 2, a groove 4 is provided on the outer wall of the extrusion block 3, the groove 4 is arranged in a ring array on the outer wall of the extrusion block 3, a limiting mechanism 5 is fixedly connected to the outer wall of one side of the rectangular sleeve 1, a movable mechanism 6 is fixedly connected to the other side of the limiting mechanism 5, the movable mechanism 6 comprises a turntable 61, a card groove 62 is provided on the outer wall of the turntable 61, a slide groove 63 is provided on the side wall of the turntable 61, a slider 64 is slidably connected to one side of the slide groove 63, a connecting rod 65 is connected to one side of the slider 64, a ball 66 is fixedly connected to the other side of the connecting rod 65, the ball 66 is movably connected to the groove 4 provided on the outer wall of the extrusion block 3, and a limiting ring 67 is fixedly connected to the inner outer wall of the turntable 61.

[0031] In this embodiment, the existing table frame design adopts a bolt connection method to ensure the firmness of the connection. However, there is a problem with this design, that is, the height of the table frame cannot be adjusted, which may cause the user to feel spinal discomfort and need to stand up to relax when working for a long time. In order to solve this problem, the design of a rectangular sleeve 1 is introduced. A connecting groove 2 is opened on one side of the rectangular sleeve 1, and an extrusion block 3 is connected to the inner wall of the connecting groove 2. The extrusion block 3 is conical in shape, with one end larger and the other end smaller, which is completely consistent with the size of the inner side of the connecting groove 2. One end of the inner side of the connecting groove 2 can be completely connected to the extrusion block 3, so that when in use, the extrusion block 3 can be completely received in the connecting groove 2, so that one side of the inner wall of the rectangular sleeve 1 is flush. Such a design can adapt to rectangular table legs of different sizes, ensuring the firmness of the connection while improving the practicality of the table;

[0032] When connecting the supporting legs, a thrust is required to achieve the effect of tightening, in order to prevent the rectangular sleeve 1 from sliding down along the outer wall of the supporting leg and falling off, so that the table frame cannot be used normally. For this purpose, a limiting mechanism 5 is provided on one side of the rectangular sleeve 1, and a movable mechanism 6 is connected to the other side of the limiting mechanism 5. By designing the movable mechanism 6, the movable mechanism 6 acts on the extrusion block 3, so that the extrusion block 3 can be pushed toward the inside of the rectangular sleeve 1 and act on the supporting leg, thereby completing the clamping effect. Specifically, a turntable 61 is provided in the movable mechanism 6, and a slot 62 is provided on the outer wall of the turntable 61. The slot 62 can be connected to the limiting mechanism 5, and a slide groove 63 is opened on the outer wall of the turntable 61. The slide groove 63 is in the form of an arc, and there are sliders 64 sliding in the slide groove 63. The two ends of the slider 64 are limited by the outer wall of the turntable 61, and the middle part slides with the inner wall of the slide groove 63 to prevent it from falling off. A connecting rod 65 is fixedly connected to one side of the slider 64, and a ball 66 is connected to the other side of the connecting rod 65. When the turntable 61 is rotated, the turntable 61 will make the slider 64 slide on the inner wall of the slide groove 63, and drive the slider 64 to deviate along the angle of the slide groove 63, so that the ball 66 can shrink inward or expand outward, and the ball 66 can act on the groove 4 opened on the outer wall of the extrusion block 3, so as to clamp the extrusion block 3, and then complete the fastening operation of the supporting foot. The limiting ring 67 provided on the inner outer wall of the rotating disk 61 can limit the connecting rod 65 to prevent the connecting rod 65 from being offset during the movement.

[0033] Example 2

[0034] like Figure 2-6 As shown, the limiting mechanism 5 includes a connecting plate 51, a threaded groove 52 is provided on the side wall of the connecting plate 51, a collar 53 is fixedly connected to the lower end of the connecting plate 51, a connecting column 54 is fixedly connected to the inner wall of the collar 53, a connecting bearing 55 is fixedly connected to the other side of the connecting column 54, and the connecting bearing 55 includes a connecting block 551, an outer wall of the other side of the connecting block 551 is fixedly connected to the outer wall of one side of the rotating disk 61, a mounting groove 552 is provided on one side of the connecting block 551, and the inner wall of the mounting groove 552 is provided with a There is a round ball 553, and a connecting block 554 is provided on the other side of the round ball 553. The outer wall of one side of the connecting block 554 is fixedly connected to the outer wall of one side of the connecting groove 2. The outer wall of the connecting block 1 551 is movably connected to a limiting sleeve 555. The inner wall of the limiting sleeve 555 is fixedly connected to the outer wall of one side of the connecting block 554. The upper end of the outer wall of one side of the ring 53 is fixedly connected with a connecting piece 56. The outer wall of one end of the connecting piece 56 is rotatably connected with a clamping block 57. The clamping block 57 is clamped with a clamping groove 62 opened on the outer wall of the turntable 61.

[0035] In this embodiment, in the design, the movable mechanism 6 needs to clamp and tighten the extrusion block 3 when rotating. However, we found that the movable mechanism 6 lacks a connector 56 that can move relative to the rectangular sleeve 1. To solve this problem, a limiting mechanism 5 is introduced. The limiting mechanism 5 includes a connecting plate 51, and the four corners of the outer wall of the connecting plate 51 are provided with thread grooves 52. These thread grooves 52 are connected with bolts to connect the connecting plate 51 with the crossbeam to achieve position fixation. A collar 53 is provided at the lower end of the connecting plate 51, and a connecting column 54 is provided in an annular array on the inner wall of the collar 53, and a connecting bearing 55 is connected to the inner side of the connecting column 54. The two ends of the connecting bearing 55 are respectively connected to the rectangular sleeve 1 and the movable mechanism 6, which plays a role in supporting the position of the movable mechanism 6. Rebound may occur when the movable mechanism 6 rotates, so a connecting member 56 is provided on one side of the connecting plate 51. The outer wall of the connecting member 56 is limitedly connected with a clamping block 57, and the sharp corner of one end of the clamping block 57 is correspondingly connected to the clamping groove 62 to achieve the limiting effect on the rotating disk 61. Through such a design, the movable mechanism 6 can clamp the extrusion block 3 when rotating, and support and fix its position through the limiting mechanism 5. At the same time, the springback is limited by the connecting member 56 and the clamping block 57, so that the operation of the entire connection structure is more stable;

[0036] In the design, the connecting bearing 55 is constructed to include a connecting block 1 551, and a connecting block 2 554 is connected to one side of the connecting block 1 551. A mounting groove 552 is provided at the connection between the connecting block 1 551 and the connecting block 2 554, and a plurality of round balls 553 are arranged in a circular array on the inner wall of the mounting groove 552. One end of the connecting block 2 554 is fixedly connected to the rectangular sleeve 1, and the outer wall of the connecting block 2 554 is fixedly connected to the limiting sleeve 555. The other end of the limiting sleeve 555 is limitedly connected to the connecting block 1 551, and the other end of the connecting block 1 551 is connected to the rotating disk 61. In this design, the effect of the round balls 553 makes the rotation of the rotating disk 61 drive the connecting block 1 551 to rotate together. Since the connecting block 1 551 is affected by the round balls 553 and the limiting sleeve 555, it will not fall or deviate, thereby ensuring the stability of the mutual connection and relative movement between the movable mechanism 6 and the rectangular sleeve 1. This structure ensures the reliability of the structure, so that the connection between the movable mechanism 6 and the rectangular sleeve 1 remains stable during the movement.

[0037] Working principle:

[0038] like Figure 1-6As shown, when the utility model is used, when the rectangular sleeve 1 is connected to the supporting leg, when it is moved to the desired position, the extrusion block 3 is pushed inward. At this time, by rotating the turntable 61, the turntable 61 will drive the slider 64 connected to the inner wall of the slide groove 63 to slide inward. The slider 64 then drives the connecting rod 65, and the connecting rod 65 drives the ball 66 to shrink inward. The function of the ball 66 is to interact with the groove 4 on the outer wall of the extrusion block 3 to clamp the extrusion block 3 to ensure that it will not loosen. In order to prevent the turntable 61 from rebounding, a connecting member 56 is provided on the outer wall of one side of the collar 53, and a clamping block 57 connected to one end of the connecting member 56 is connected to the clamping groove 62, which plays a role of limiting and fixing the position of the turntable 61. When the turntable 61 rotates, one side of it is connected to the connecting block 1 551. The movement of the turntable 61 will drive the connecting block 1 551 to move relative to each other through the coordinated action of the ball 553, the connecting block 2 554 and the limiting sleeve 555. The second connection block 554 is fixedly connected to the outer wall of one side of the rectangular sleeve 1 to ensure stable connection and support between the movable mechanism 6 and the rectangular sleeve 1. This design realizes the clamping and tightening effect of the support legs through the rotation of the turntable 61, and at the same time, through the limiting of the connection piece 56 and the clamping block 57, it is ensured that the position of the turntable 61 can be firmly fixed, making the operation of the entire system more stable.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields.
