Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lifting table accessories, in particular to a mounting beam of lifting table. BACKGROUND

[0002] With the increasing requirements of modern office and home environment on human health and use flexibility, lifting tables have been widely used. In the structural design of lifting tables, the mounting beam is one of the most critical components, which mainly serves to connect the tabletop and other components such as table legs to ensure the stability and reliability of the entire lifting table structure.

[0003] Traditional lifting table mounting beams mostly adopt a whole rod structure. Such a mounting beam has the characteristics of high integrity and relatively simple manufacturing process (such as the horizontal beam 7 in the lifting table leg disclosed in application No. CN2020229779452). However, since it is integrally formed, its length is fixed after manufacturing and cannot be adjusted according to different tabletop sizes or use scenarios. For example, when facing different sizes of tabletops, if the tabletop size does not match the length of the mounting beam, it may cause installation difficulties or unstable structure after installation, greatly limiting its application range.

[0004] Another common mounting beam structure is a form of connection of multiple sleeves. Although this structure increases the flexibility of the mounting beam to some extent, the multiple sleeves are usually fixed by bolts (such as the support horizontal beam 3 in the office table disclosed in application No. CN202023163688.5). Once the bolts are fixed, the total length is also fixed and cannot be adjusted again.

[0005] Therefore, whether it is a whole structure mounting beam or a multiple sleeve structure mounting beam, its non-adjustable feature determines that a type of mounting beam can only adapt to one specific type of tabletop. This not only increases the types of mounting beams in the production process and the inventory management cost, but also cannot be flexibly adapted when the tabletop needs to be replaced or adjusted in actual use scenarios, bringing many inconveniences to users and being not conducive to the diversification and individualization development of lifting table products. Therefore, it is necessary to develop a new type of lifting table mounting beam structure that can effectively solve the above problems to meet the increasingly diversified market demand and different application requirements.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0021] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0022] The utility model provides a mounting beam of lifting table.

[0023] In the embodiment, referring to Figs. 1-3 The mounting beam of the lifting table comprises a middle sleeve pipe 1 and outer sleeve pipes 2 located at both ends of the middle sleeve pipe 1. The end of the middle sleeve pipe 1 is provided with an elastic connection structure. The elastic connection structure comprises a fixed plate 3, a telescopic piece 4, a pop-up spring 5 and a fine adjustment nut 6. The telescopic piece comprises a hemispheres 7 and a screw rod 8 connected to the hemispheres. The screw rod 8 movably penetrates through the through hole 9 in the outer wall of the middle sleeve pipe and the fixed plate and is screwed with the fine adjustment nut. One end of the pop-up spring is fixedly connected with the fixed plate, and the other end is fixedly connected with the hemispheres. The pop-up spring has a spring force for popping the hemispheres out of the through hole in the outer wall of the middle sleeve pipe. A plurality of connecting holes 10 capable of being mutually embedded with the hemispheres are arranged at equal intervals along the outer wall of the outer sleeve pipe.

[0024] In the technical solution, the elastic connecting structure is used to connect the middle sleeve and the outer sleeve, so that the length of the mounting beam can be adjusted. The half-sphere of the telescopic part is inserted into the connecting hole at different positions of the outer sleeve through the elastic spring, so that the mounting beam can be conveniently adapted to various sizes of desktops, greatly improving the versatility of the mounting beam, reducing the need for special mounting beams of different lengths due to changes in the size of the desktop, and reducing production costs and inventory management difficulties.

[0025] The adjustment steps of the mounting beam of the lifting table are as follows:

[0026] Initial preparation: First, place the lifting table on a stable work surface to ensure that the mounting beam is not under stress and can be operated. Check all parts of the elastic connecting structure, including the fixed plate, telescopic part, elastic spring, and fine adjustment nut, to ensure that they are not damaged, jammed, and that the elastic spring can freely expand and the half-sphere can smoothly move in the through hole on the outer wall of the middle sleeve under the action of the spring force.

[0027] Release the half-sphere: rotate the fine adjustment nut counterclockwise to gradually release the pressure on the half-sphere. Under the action of the elastic force of the elastic spring, the half-sphere will be ejected a certain distance from the through hole on the outer wall of the middle sleeve. At this time, the half-sphere is ready for embedding operation with the connecting hole on the outer sleeve.

[0028] Select the connecting hole: according to the required length of the mounting beam, observe the connecting holes arranged at equal intervals along the outer wall of the outer sleeve to determine the appropriate connecting hole position. When selecting the connecting hole, consider the size of the desktop, the design height of the lifting table, and the mechanical requirements in the actual use scenario to ensure that the mounting beam can provide stable support after adjustment and meet the adaptability of the overall structure.

[0029] Embedding operation: gently push or pull the middle sleeve relative to the outer sleeve to align the half-sphere with the selected connecting hole of the outer sleeve. When the half-sphere is aligned with the connecting hole, the half-sphere will automatically embed into the connecting hole under the action of the elastic force of the elastic spring, realizing the preliminary connection of the middle sleeve and the outer sleeve. Finally, rotate the fine adjustment nut clockwise to adjust the elastic force of the elastic spring to the appropriate position.

[0030] Specifically, the fixed plate and the middle sleeve are connected by welding.

[0031] In this embodiment, the fixed plate and the middle sleeve are connected by welding, ensuring the firmness and stability of the connection between the fixed plate and the middle sleeve.

[0032] Specifically, the outer end of the outer sleeve is provided with a fixing hole 12 for connecting the support pipe 11.

[0033] In the embodiment, the outer sleeve outer end is provided with a fixing hole for connecting the support pipe, so that the mounting beam can be connected with the support pipe closely and stably, and a complete lifting table frame structure is constructed. The fixing hole provides accurate positioning and reliable connection point for the installation of the support pipe.

[0034] Specifically, an arrow mark 13 is arranged on the outer wall of the outer sleeve at one end of the fixing hole.

[0035] In the embodiment, the arrow mark is arranged on the outer wall of the outer sleeve at one end of the fixing hole, which provides clear direction guidance for the installer when connecting the support pipe. This helps to improve the installation efficiency and reduce installation failure or rework caused by incorrect installation direction, especially when large-scale production or users assemble the lifting table by themselves, which can significantly reduce the probability of incorrect installation and ensure the smooth progress of the installation process.

[0036] Specifically, the middle part of the middle sleeve is fixed with an "L"-shaped fastening plate 14 through bolts.

[0037] In the embodiment, the middle part of the middle sleeve is fixed with an "L"-shaped fastening plate 14 through bolts, which is used for fixed connection with the table top. The stability of the connection between the mounting beam and the table top is ensured.

[0038] Skilled persons should know that although the utility model has been described according to the above specific embodiments, the utility model idea is not limited to the utility model, and any modification using the utility model idea will be included in the patent protection range.
