Description

Technical Field

[0001] The utility model belongs to the technical field of household articles for daily use, and particularly relates to a quick-release structure for a foot tube. Background Art

[0002] At present, there are mostly two connection methods between the cross beam and the table leg assembly of tables on the market: one is that the cross beam and the table leg are integrally formed, and the other is that the cross beam and the table leg are separated. When the cross beam and the table leg are integrally formed, since the cross beam and the table leg cannot be disassembled, the occupied packaging volume is relatively large, which is not convenient for increasing the transportation quantity. The other is that the cross beam and the table leg are separated to achieve the purpose of convenient storage and transportation.

[0003] In the prior art, for tables with a separated cross beam and table legs, the common connection method between the table legs and the cross beam is screw fixation. The above connection method has the defects of having many components, being prone to losing accessories, having complex disassembly and assembly steps, requiring tools, taking a long time for assembly, and being inconvenient to use. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a quick-release structure for a foot tube to solve the technical problem of inconvenient installation of table legs for a separated table.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0006] A quick-release structure for a foot tube includes a table frame, a limiting component and a locking component. Limiting components are provided at the four corners of the table frame. The limiting component includes two foot tube fixing parts.

[0007] The locking component includes a connecting rod and a trigger. The connecting rod passes through the two foot tube fixing parts, and a positioning part is fixed at one end, and the positioning part is used to limit the connecting rod from sliding out of the foot tube fixing part. The trigger is rotatably connected to the other end of the connecting rod and is eccentrically arranged, and can control the locking or unlocking of the relative position between the two foot tube fixing parts by rotating the trigger, thereby realizing the fixing or loosening of the table legs.

[0008] Further, the fixing part is a nut.

[0009] Further, the two foot tube fixing parts are two fixed plates oppositely arranged and fixed on the two side walls at the corner of the table frame; a foot tube installation groove is formed between the inner side of the fixed plate and the table frame.

[0010] Further, the outer end edges of the two fixed plates are provided with installation edges; the two installation edges are arranged at intervals. Through holes adapted to the connecting rod are formed on the installation edges. The connecting rod passes through the two through holes, and the positioning part and the trigger are respectively arranged outside the through holes.

[0011] Further, the two leg tube fixing members are respectively a limiting plate fixed on the table frame and a connecting plate provided on the leg tube. Mounting holes and relief grooves adapted to the connecting rod are respectively formed on the limiting plate and the connecting plate. The connecting rod sequentially passes through the relief groove and the mounting through hole, and can lock the relative positions of the limiting plate and the connecting plate under the cooperation of the positioning member and the buckle.

[0012] Further, a mounting bracket is fixed on the bottom surface of the limiting plate. An assembly groove adapted to the leg tube is formed at the bottom of the mounting bracket.

[0013] Further, limit members are provided at the tops of the two leg tube fixing members.

[0014] Further, a connecting rope is provided on the leg tube fixing member, and the other end of the connecting rope is connected to the leg tube.

[0015] Compared with the prior art, the present utility model has the following advantages:

[0016] The present utility model is provided with two leg tube fixing members for defining the positions of the table legs on the table frame, and a connecting rod is provided on the two leg tube fixing members. The connecting rod passes through the two leg tube fixing members, and a nut is fixed at one end. The buckle is rotatably connected to the other end of the connecting rod and is eccentrically arranged, and can control the locking or unlocking of the relative positions between the two leg tube fixing members through the rotation of the buckle, thereby realizing the fixing or loosening of the table legs. While streamlining the disassembly and assembly steps, it avoids the loss of accessories for installation.

[0017] The present utility model is provided with a connecting rope on the table frame. The other end of the connecting rope is connected to the leg tube, which can effectively avoid the loss of the leg tube. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, it should not be construed as a limitation to the present utility model.

[0024] The present utility model will be further described below with reference to the drawings.

[0025] Embodiment 1

[0026] As Figure 1 and 2 shown, a quick-release structure for a foot tube includes a table frame 1, a limiting component 2, and a locking component 3. Among them, limiting components 2 are provided at the four corners of the table frame 1. The limiting component 2 includes two foot tube fixing members 2-1. The two foot tube fixing members 2-1 are respectively fixed on the two side walls at the corners of the table frame 1, and a foot tube installation groove is formed between the inner sides and the table frame 1. During installation, the foot tube is inserted into the foot tube installation groove.

[0027] The two foot tube fixing members 2-1 are respectively two fixing plates fixed on the two side walls at the corners of the table frame. The outer end edges of the two fixing plates are provided with mounting edges 2-2 formed by bending. The two mounting edges 2-2 are arranged at intervals, and an opening structure is formed between them. The two mounting edges 2-2 can approach each other under the control of the locking component 3, thereby realizing the locking of the inserted foot tube.

[0028] The specific structure is as follows, as Figure 2 and 3As shown in the figure, the locking assembly 3 includes a connecting rod 3-1, a positioning member, and a trigger 3-3. Among them, through holes adapted to the connecting rod 3-1 are provided on the mounting edges 2-2 of the two foot tube fixing members 2-1. The connecting rod 3-1 passes through the two through holes, and one end is locked by the positioning member, which can limit the connecting rod 3-1 from sliding out of the foot tube fixing member 2-1. The trigger 3-3 is rotatably connected to the other end of the connecting rod 3-1 and is an eccentric structure. In the initial state, the side of the outer ring of the trigger closer to the center of the rotation axis fits with the corresponding mounting edge 2-2. During assembly, by rotating the trigger 3-3, the side of the outer ring of the trigger farther from the center of the rotation axis gradually approaches the corresponding mounting edge 2-2. Under the combined action of the positioning member and the trigger, the two mounting edges 2-2 approach each other, thereby realizing the change in the size of the opening structure between the mounting edges 2-2 and completing the clamping and fixing of the foot tube.

[0029] In this embodiment, the fixing member is a nut 3-2. Limit members 4 are provided at the tops of the two foot tube fixing members 2-1 to limit the extreme positions of the insertion of the foot tubes and ensure that the insertion depths of each foot tube are the same.

[0030] Embodiment 2

[0031] A quick-release structure for a foot tube includes a table frame 1, a limit assembly 2, and a locking assembly 3. Among them, limit assemblies 2 are provided at the four corners of the table frame 1 to limit the positions of the foot tubes.

[0032] The limit assembly 2 includes two foot tube fixing members 2-1. The two foot tube fixing members 2-1 are respectively a limit plate 2-3 fixed on the table frame 1 and a connecting plate 2-5 provided on the foot tube. Among them, a mounting bracket 2-4 is fixed on the bottom surface of the limit plate 2-3. An assembly groove adapted to the foot tube is provided at the bottom of the mounting bracket 2-4. The table leg is inserted into the assembly groove and is locked under the combined action of the limit plate 2-3, the connecting plate 2-5, and the locking assembly 3.

[0033] As Figure 4 As shown in the figure, the locking assembly 3 includes a connecting rod 3-1, a positioning member, and a trigger 3-3. Among them, mounting holes and relief grooves adapted to the connecting rod 3-1 are respectively provided on the limit plate 2-3 and the connecting plate 2-5. The connecting rod 3-1 passes through the relief groove and the mounting through hole in sequence, and the relative positions of the limit plate 2-3 and the connecting plate 2-5 are locked under the cooperation of the positioning member and the trigger 3-3. The trigger 3-3 is rotatably connected to the connecting rod 3-1 and is of an eccentric structure.

[0034] During assembly, the leg is inserted into the assembly groove, and the clearance groove on the connecting plate 2-5 installed on the leg is aligned with the mounting hole. The connecting rod 3-1 passes through the clearance groove and the mounting hole in sequence, and the end is defined by the positioning piece. At this time, the side of the outer ring on the buckle closer to the center of the rotating shaft fits with the connecting plate 2-5. By rotating the buckle 3-3, the side of the outer ring on the buckle farther from the center of the rotating shaft gradually approaches the connecting plate 2-5. Under the cooperation of the positioning piece and the buckle, the connecting plate 2-5 and the limiting plate 2-3 are brought closer to each other, thereby realizing the change in the distance between the connecting plate 2-5 and the limiting plate 2-3, and completing the clamping and fixation of the leg.

[0035] In this embodiment, the positioning member is a nut 3-2.

[0036] Furthermore, a connecting rope 5 is connected to the limiting plate 2 - 3 , and the other end of the connecting rope 5 is connected to the leg tube, which can prevent the leg tube from being lost after disassembly.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
