Description

Technical Field

[0001] The invention relates to the technical field of dry gas sealing, in particular to a width-adjustable table frame. Background Art

[0002] In modern office and home scenes, the height-adjustable table has become a popular furniture device favored by the public due to its outstanding features of flexible height adjustment and adaptability to multiple usage needs. The connection structure between the table legs and the support pad is a key component of the height-adjustable table. Its design quality is directly related to the product installation efficiency, stability during use, and convenience of later maintenance.

[0003] At present, most lifting tables in the market still rely on traditional screw fastening methods to connect the table legs and support pads. In the actual installation process, installers have to use various tools to carry out the operation. The whole process is extremely cumbersome, not only consuming a lot of time, but also requiring a lot of manpower costs. Furthermore, given the diverse demands for desktop sizes in the market, it is undoubtedly a very challenging task to tailor a dedicated table frame for each desktop of different sizes. If an innovative design can be made to produce a flexible and changeable table frame that can be freely adjusted according to the size of the desktop, it will effectively promote a significant reduction in costs and significantly improve production and installation efficiency.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 6 The present invention provides a width-adjustable table frame, which includes two table legs and crossbeam assemblies 1 respectively connected to the table legs, a support beam 2 is connected between the two crossbeam assemblies 1, and the crossbeam assembly 1 and the support beam 2 are plugged and slidably matched to adjust the width between the two table legs, and the sliding fit will be locked by a fixing member 3.

[0020] In the specific implementation of the present application, the beam assembly 1 includes a first beam 11 for fixing the desktop support, which is distributed longitudinally, and a second beam 12 for adjusting the width of the table legs, which is distributed transversely. The first beam 11 and the second beam 12 are integrally arranged, and the second beam 12 is used for plugging and sliding with the support beam 2.

[0021] Furthermore, two second cross beams 12 are provided, both of which extend from one side of the first cross beam 11 and are arranged in parallel. Connectors 4 are installed between the second cross beams 12 for reinforcement. The second cross beam 12 is a hollow structure with one end open to form a slideway 13. Two support beams 2 are provided, and both ends thereof are respectively inserted into the slideways 13 of the second cross beams 12 located on both sides for sliding fit.

[0022] In a specific embodiment of the present application, the fixing member 3 is installed on the supporting beam 2 and is clamped with the second cross beam 12 to fix the second cross beam 12 and the supporting beam 2 .

[0023] Specifically, the fixing member 3 includes a fixing seat 31 and a supporting member 32. The fixing seat 31 is installed on the upper surface of the supporting beam 2. Two first elastic buckles 33 are arranged on the bottom surface of the fixing member 3, a second elastic buckle 34 is arranged on the top surface, and a third elastic buckle 35 is arranged on the supporting member 32. First, a plurality of fixing holes are evenly arranged on the support beam 2 for serving as fixing points 5 for installing the fixing seat 31. The first elastic buckle 33 on the bottom surface of the fixing seat 31 passes through the fixing hole and is clamped and fixed to the support beam 2; the first elastic buckle 33 is composed of two symmetrically distributed first spring pieces 331 and second spring pieces 332 with protrusions on the sides. When the first elastic buckle 33 is clamped in the fixing hole, the first spring piece 331 and the second spring piece 332 are elastically expanded outward and fit tightly in the fixing hole. The protrusions and the main body of the fixing seat 31 are distributed on both sides of the fixing hole, so that the fixing seat 31 is firmly fixed on the support beam 2.

[0024] Secondly, the support member 32 is sleeved on the support beam 2. The support member 32 is set in the shape of a sleeve with two ends open. One end of the support member 32 is adapted to the support beam 2, and the other end is adapted to the support beam 2 plus the fixed seat 31, so that the support member 32 has a space that can just wrap the fixed seat 31. After the fixed seat 31 is fixed to the support beam 2, the fixed seat 31 can block the sliding path of the support member 32. At this time, the support member 32 is in contact with the support beam 2 and the fixed seat 31. In addition, the fixed seat 31 and the support member 32 are respectively provided with a groove 1 36 and a groove 2 37. The second elastic buckle 34 and the third elastic buckle 35 have the same structure, and both are upwardly tilted springs arranged in the groove 1 36 and the groove 2 37, and a convex block 38 is integrally provided on the upper surface of the spring. When the support member 32 wraps the fixed seat 31, the convex block 38 of the second elastic buckle 34 is stuck in the groove 2 37. First, the fixing seat 31 is fixed on the supporting beam 2 , and then the supporting member 32 is fixed on the supporting beam 2 through the fixing seat 31 .

[0025] Finally, a small hole 14 is opened at the end of the second cross beam 12, and the protrusion 38 of the third elastic buckle 35 can be inserted into the small hole 14 to clamp the second cross beam 12, completing the fixing piece 3 to lock and fix the cross beam assembly 1 and the support beam 2.

[0026] It needs to be further explained that the fixing member 3 is not a flexible and detachable structure. The table frame structure of the present application has an adjustable effect during the installation process, and is adaptively adjusted according to the size of the desktop. After the fixing point 5 is selected and the fixing seat 31 is firmly fixed on the support beam 2, it will not be easily removed. Then the support member 32 is fixed to the support beam 2 through the fixing seat 31, and then the second beam 12 is fixed through the support member 32. In the present application, the support member 32 is used to support the stability of the support beam 2 sliding on the second beam 12. It has a large support surface to ensure the problem of sliding. Although the cooperation of the fixing seat 31 and the support member 32 is required, the elastic buckle can achieve stability with a small number of buckles.

[0027] In some embodiments, the support member 32 may be omitted, but the fixing seat 31 needs to be extended and the number of the first elastic buckles 33 needs to be increased to increase the stability of the cooperation between the second cross beam 12 and the support beam 2 .

[0028] In a preferred embodiment, the support member 32 can be installed in the sliding of the second cross beam 12, and the fixing seat 31 can be installed on the support beam 2. When the second cross beam 12 and the support beam 2 are plugged in, the support member 32 and the fixing seat 31 are clamped together to complete the fixation.

[0029] In some embodiments, a slideway may be provided in the support beam 2 to allow the second cross beam 12 to be inserted and slid therein.
