Description

Technical Field

[0001] This utility model relates to a bracket, and more particularly to a crossbar bracket. Background Technology

[0002] In China, playing mahjong, a long-standing and widely popular traditional entertainment activity, is enjoyed by people of all ages and has become an important part of daily leisure and entertainment. With the popularization of this form of entertainment, various mahjong parlors have sprung up in every corner of the city, providing convenient entertainment venues for people, whether professional card and board game clubs or small mahjong parlors in neighborhoods.

[0003] In the operation of mahjong parlors and various card and board game rooms, chairs are an indispensable piece of infrastructure, numerous and used very frequently. Currently, common card and board game room chairs on the market mainly consist of three parts: the chair frame, the backrest, and the base. The chair frame, as the main supporting structure, typically includes a left support, a right support, and a crossbar support located between them. The crossbar support plays a crucial connecting and stabilizing role in the chair structure; it not only enhances the overall strength of the chair frame but also provides additional support points for the user, improving comfort.

[0004] However, most existing methods of connecting the crossbars and the left and right supports use welding. While this welding method can ensure the stability of the structure to a certain extent, the fixed connection formed by welding makes the entire chair a non-removable unit, which is extremely inconvenient during transportation and assembly.

[0005] Therefore, it is necessary to develop a new type of crossbar support connection structure to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a horizontal support bracket.

[0007] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0008] A crossbar support includes a connecting rod, with locking blocks welded to both ends of the connecting rod. The locking blocks have a U-shaped cross-section, and threaded holes penetrating the locking blocks are provided at both ends of the connecting rod. Mounting holes are also provided on the left and right sides of the connecting rod.

[0009] The threaded hole is used with a long bolt.

[0010] When using this crossbar support, the chair frame needs to be connected to the crossbar support, which has a connection hole. Then, the two side clips are engaged with the left and right brackets on the chair frame. Finally, long bolts are used to connect the crossbar support to the connection hole and bolt hole.

[0011] The mounting holes are used to install the base.

[0012] The beneficial effects of this utility model are:

[0013] This invention achieves a detachable connection between the crossbar support and the chair frame by setting U-shaped locking blocks and threaded holes through the locking blocks at both ends of the connecting rod, and connecting them with the left and right supports of the chair frame using long bolts. This solves the problem of existing welding connections that prevent the chair from being disassembled, making transportation and assembly extremely inconvenient. Therefore, this invention facilitates the transportation and assembly of the chair. Attached Figure Description

[0015] Figure 2 This is a schematic diagram of the structure of this utility model.

[0016] Among them, 1-connecting rod; 2-clamping block; 3-threaded hole; 4-mounting hole; 5-long bolt; 6-chair bracket; 7-bracket; 8-connecting hole. Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] A crossbar support includes a connecting rod 1, with locking blocks 2 welded to both ends of the connecting rod 1. The locking blocks 2 have a U-shaped cross section, and threaded holes 3 penetrating the locking blocks are provided at both ends of the connecting rod 1. Mounting holes 4 are also provided on the left and right sides of the connecting rod 1.

[0019] The threaded hole 3 is used in conjunction with the long bolt 5.

[0020] When using this crossbar support, the chair frame 6 needs to be connected to the support 7 of the crossbar support, which has a connection hole 8. Then, the two side clips 2 are engaged with the support 7 of the left and right supports on the chair frame 6. Finally, the long bolts 5 are used to connect them together with the connection hole 8 and the bolt hole 3.

[0021] Mounting hole 4 is used to install the base.

[0022] The implementation principle of this utility model is as follows: When implementing the crossbar support, firstly, the support 7 to be connected on the chair frame 6 is provided with a connecting hole 8. Since the connecting rod 1 has a U-shaped cross section 2 welded at both ends and a threaded hole 3 through the 2, the threaded hole 3 can be used with a long bolt 5. The connecting rod 1 is also provided with mounting holes 4 on the left and right sides. The 2 at both ends of the connecting rod 1 is engaged with the support 7 in the left and right supports on the chair frame 6, so that the connecting hole 8 is aligned with the threaded hole 3. Then, the long bolt 5 is used to connect them together through the connecting hole 8 and the threaded hole 3. The mounting hole 4 is used to install the base.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
