Description

Technical Field

[0001] The utility model relates to the technical field of design auxiliary tools, in particular to a telescopic bottom bracket. Background Art

[0002] The bottom bracket of a countertop wash basin, face basin, or vegetable sink is usually a safety auxiliary support structure used to fix and support these basins so that they can be stably installed under the countertop. The bracket can be designed in different forms, such as metal brackets, plastic brackets, or wooden brackets, depending on the material and design requirements of the basin. The main function of the bracket is to ensure the stability and safety of the basin during use, while also facilitating installation and maintenance.

[0003] In the prior art, the bracket needs to be customized according to the size of the countertop wash basin, wash basin or vegetable sink. When a countertop basin of a different size needs to be replaced, the bracket of the same specification needs to be replaced accordingly, which is not only not very applicable but also increases additional costs. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a telescopic bottom bracket.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a telescopic bottom bracket, including a wall fixing plate, the side of the wall fixing plate is fixed with a wall by bolts, the top of the wall fixing plate is fixed with a first plane support plate, a force-expanding beam is fixed between the bottom of the first plane support plate and the side wall of the wall fixing plate, a movable groove is provided on one side of the force-expanding beam, a movable beam is slidably connected inside the movable groove, a support beam is fixed on the side of the movable beam, a second plane support plate is fixed on the top of the support beam, and another wall fixing plate is fixed on the side of the support beam, screw holes are arranged in an array on the surface of the movable groove and the movable beam, and the movable beam is fixed to the movable groove with bolts.

[0006] Preferably, an anti-corrosion pad is provided at the connection between the movable groove and the movable beam. The anti-corrosion pad can absorb the vibration between the movable beam and the movable groove, reduce the impact and wear on the connection part, and install and use the anti-corrosion pad to reduce the maintenance and replacement costs caused by corrosion.

[0007] Preferably, adjustable bolt holes are provided on the side of the wall panel. The adjustable bolt holes allow fine-tuning of the position of the wash basin during installation, ensuring that it is precisely docked with the under-counter basin and the countertop to make up for the uneven error in glue thickness when bonding and installing it, so that the bracket can truly play a supporting, stable and safe role, reducing installation problems caused by inaccurate measurement or hole drilling, and the adjustable bolt hole design enables the bracket to adapt to slight changes in the wall, ensuring that the wash basin can be firmly installed on an imperfect wall.

[0008] Preferably, the wall panel is fixed to the wall using expansion bolts. Expansion bolts can be used for a variety of materials. Whether it is a brick wall, concrete wall or other types of walls, expansion bolts can provide a reliable fixing effect, and the installation process only requires drilling, inserting bolts and tightening, which simplifies the operation steps.

[0009] Preferably, the side array of the wall panel is provided with self-tapping screw holes, and the self-tapping screw holes are symmetrically arranged at both ends of the adjustable bolt hole. In order to ensure that the wash basin does not shake or tilt during use, the bracket is usually fixed to the angle steel bracket or the wall. The self-tapping screws used in the utility model can not only be directly drilled into the preset material without the need for pre-drilling, which greatly speeds up the installation speed, but also have high tensile strength, ensuring stability and durability after fixation.

[0010] Preferably, the ends of the force-spreading beam and the support beam close to the wall panel are both set as inclined planes, which increases the cross-sectional inertia moment of the force-spreading beam and the support beam, thereby enhancing their overall rigidity. When subjected to external force, their deformation will be significantly reduced, thereby ensuring the stability and safety of the structure.

[0011] Preferably, the number of bolts used to fix the movable beam and the movable groove is not less than two. The use of multiple bolts can more evenly disperse the stress acting on the connection between the beam and the groove, avoid damage caused by stress concentration, and effectively prevent the beam from twisting or rotating when subjected to force, thereby maintaining the stability and safety of the bracket structure. More bolts mean a larger load-bearing area, thereby improving the load-bearing capacity of the bracket.

[0012] Beneficial effects

[0013] In the prior art, the bracket needs to be customized and used according to the size of the under-counter wash basin, wash basin or vegetable sink. When it is necessary to replace the under-counter basin of different sizes, the bracket of the same specifications needs to be replaced accordingly. Not only is the applicability low, but it also increases the extra cost. To address this problem, the utility model adopts an adjustable and telescopic bottom bracket, and inserts the movable telescopic beam into the movable groove. The movable beam is moved according to the size of the under-counter wash basin, wash basin or vegetable sink, and the screw holes on the surface of the movable telescopic beam are matched with the screw holes on the surface of the movable groove until the bracket is consistent with the size of the under-counter basin, and then the bolts are tightened into the screw holes corresponding to the movable beam and the movable groove to fix them. Finally, the wall panel is fixed to the wall with expansion bolts. The adjustable bracket can adapt to wash basins of different sizes, provides greater flexibility, and facilitates users to choose a suitable wash basin according to their needs, simplifies the installation process, and users can adjust according to the actual space and the size of the wash basin without complicated customization or modification.
