[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a width-adjustable table frame, which includes two table legs and crossbeam assemblies 1 connected to the table legs respectively. A support beam 2 is connected between the two crossbeam assemblies 1. The crossbeam assemblies 1 and the support beam 2 are inserted and slidably engaged to adjust the width between the two table legs. The sliding engagement is locked by a fixing member 3.

[0027] In a specific embodiment of this application, the crossbeam assembly 1 includes a first crossbeam 11 for fixing the tabletop support, which is longitudinally distributed, and a second crossbeam 12 for supporting the width adjustment of the table legs, which is transversely distributed. The first crossbeam 11 and the second crossbeam 12 are integrally formed, and the second crossbeam 12 is used for inserting and sliding with the support beam 2.

[0028] Furthermore, two second crossbeams 12 are provided, both extending from one side of the first crossbeam 11 and arranged in parallel. Connectors 4 are installed between the second crossbeams 12 for reinforcement. The second crossbeam 12 is a hollow structure with one end open to form a slide 13. Two support beams 2 are provided, and their two ends are also inserted into the slides 13 of the second crossbeams 12 on both sides for sliding engagement.

[0029] In a specific embodiment of this application, the fastener 3 is installed on the support beam 2 and is fixed to the support beam 2 by the second crossbeam 12 locking post.

[0030] Specifically, the fastener 3 includes a fixing seat 31 and a support 32. The fixing seat 31 is installed on the upper surface of the support beam 2. The bottom surface of the fastener 3 is provided with two first elastic buckles 33, the top surface is provided with a second elastic buckle 34, and the support 32 is provided with a third elastic buckle 35.

[0031] First, multiple fixing holes are evenly arranged on the support beam 2 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 fixed to the support beam 2. The first elastic buckle 33 is composed of two symmetrically distributed first elastic pieces 331 and second elastic pieces 332 with protrusions on the sides. When the first elastic buckle 33 is engaged in the fixing hole, the first elastic pieces 331 and second elastic pieces 332 have an outward elasticity and fit tightly in the fixing hole. The protrusions and the body of the fixing seat 31 are distributed on both sides of the fixing hole, which firmly fixes the fixing seat 31 to the support beam 2.

[0032] Secondly, the support member 32 is sleeved on the support beam 2. The support member 32 is designed as a sleeve shape with open ends. One end is adapted to the support beam 2, and the other end is adapted to the support beam 2 plus the fixing seat 31, so that the support member 32 has a space that can just cover the fixing seat 31. After the fixing seat 31 is fixed to the support beam 2, the fixing 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 fixing seat 31. In addition, the fixing seat 31 and the support member 32 are respectively provided with a first groove 36 and a second groove 37. The second elastic buckle 34 and the third elastic buckle 35 have the same structure. They are both upward-curved spring pieces set in the first groove 36 and the second groove 37, and a protrusion 38 is integrally formed on the upper surface of the spring piece. When the support member 32 covers the fixing seat 31, the protrusion 38 of the second elastic buckle 34 is engaged in the second groove 37. First, the fixing seat 31 is fixed to the support beam 2, and then the support member 32 is fixed to the support beam 2 through the fixing seat 31.

[0033] Finally, a small hole 14 is made at the end of the second crossbeam 12, and the protrusion 38 of the third elastic buckle 35 can be inserted into the small hole 14 to lock the second crossbeam 12 into place, thus completing the fastener 3 to lock and fix the crossbeam assembly 1 and the support beam 2.

[0034] It needs further explanation that the fixing member 3 is not a flexible and detachable structure. The table frame structure of this application is adjustable during installation, adapting to different tabletop sizes. After selecting the fixing point 5 and firmly fixing the fixing seat 31 to the support beam 2, it is not easily removed. Then, the support member 32 is fixed to the support beam 2 through the fixing seat 31, and then the second crossbeam 12 is fixed through the support member 32. In this application, the support member 32 is used to stabilize the sliding of the support beam 2 on the second crossbeam 12. It has a large support surface to ensure the stability of the sliding. Although the cooperation of the fixing seat 31 and the support member 32 is required, stability can be achieved with a small number of elastic buckles.

[0035] In some implementations, the support member 32 can be omitted, but the fixing seat 31 needs to be extended and the number of first elastic buckles 33 needs to be increased accordingly to increase the stability of the second crossbeam 12 in conjunction with the support beam 2.

[0036] In a preferred embodiment, the support member 32 can be installed in the sliding of the second crossbeam 12, and the fixing seat 31 can be installed on the support beam 2. When the second crossbeam 12 and the support beam 2 are inserted and engaged, the support member 32 and the fixing seat 31 are engaged to complete the fixation.

[0037] In some embodiments, a slide rail may be provided in the support beam 2, allowing the second crossbeam 12 to slide and insert therein.
