Description

Technical Field

[0001] This utility model relates to the field of counterweight technology, and in particular to a novel counterweight base. Background Technology

[0002] A counterweight base is a component that increases the overall weight and stability of an object by filling its interior with weight. These products are widely used in daily life; for example, billboards, parasols, clothes racks, road barriers, and fitness equipment typically require counterweights at their base to prevent tipping over due to external forces. Common counterweight bases usually consist of an outer shell and filling material. The outer shell is often made of plastic, metal, or composite materials, while the filling material includes cement, sand, stone, or other high-density materials to meet different usage scenarios and stability requirements.

[0003] For example, the prior art disclosed in CN222992037U is a novel integrated counterweight base, in which the internal filling material is a cement mixture, which is filled into the shell by pouring. However, after a long period of use, the filling material and the shell are prone to loosening, causing the filling material to shake inside the shell or even fall out of the shell, affecting the use of the counterweight base. Utility Model Content

[0004] This utility model proposes a novel counterweight base to solve the problem mentioned in the background art that the existing counterweight bases, which use direct cement pouring inside, are prone to filling material loss during use.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A novel counterweight base includes a base shell, which is a flat shell structure with one open end. A counterweight is installed in the inner cavity of the base shell. An adhesive layer is provided between the outer wall of the counterweight and the inner wall of the base shell, and between the end face of the counterweight and the inner end face of the base shell. The adhesive layer is used to fasten the counterweight to the base shell. An anti-slip pad is provided at the end of the counterweight.

[0007] Preferably, the base shell is a disc-shaped shell structure with one end open.

[0008] Preferably, the base shell has a cylindrical structure at the end near the opening.

[0009] Preferably, the base housing has an inwardly folded edge at the end near the opening.

[0010] Preferably, the anti-slip pad has a first through hole in the thickness direction, the counterweight has a stepped hole and a second through hole in the thickness direction, and the base shell has a third through hole in the thickness direction, wherein the first through hole, the stepped hole, the second through hole and the third through hole are coaxially arranged.

[0011] Preferably, the minimum inner diameter of the stepped hole is greater than the inner diameter of the second through hole.

[0012] Preferably, the first through hole is located at the center of the counterweight base.

[0013] Preferably, the base shell has a flange extending toward the counterweight at the third through hole position.

[0014] Preferably, the counterweight is a cement mixture.

[0015] Preferably, the outer surface of the base housing is provided with a pattern, coating or texture.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0017] This utility model has a reasonable design structure. The counterweight and the base shell are connected by an adhesive layer, which effectively improves the connection firmness of the counterweight inside the base shell and avoids the problem of shaking and falling off after long-term use, thus helping to extend the service life of the counterweight base.

[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] As shown in the figure, a novel counterweight base includes a base shell 1. The base shell 1 can be made of vacuum-formed plastic or metal. The base shell 1 is a flat shell structure with one open end. In this example, the base shell 1 is a disc-shaped shell structure with one open end, which is regular and aesthetically pleasing. It can be understood that it can also be designed as an irregularly shaped flat shell structure to meet different scenarios. A counterweight 2 is installed in the inner cavity of the base shell 1. The outer wall of the counterweight 2 is connected to the inner wall of the base shell 1, and the end face of the counterweight 2 is connected to the inner wall of the base shell 1. An adhesive layer 3 is provided between the end faces. The adhesive layer 3 is used to fasten the counterweight 2 to the base shell 1. Specifically, the adhesive layer 3 can be MS polymer adhesive, two-component polyurethane structural adhesive, etc. Since the counterweight 2 is bonded to the base shell 1 in both the circumferential and end directions, the probability of the counterweight 2 falling off can be reduced, thereby extending the service life of the overall counterweight 2. The end position of the counterweight 2 is provided with an anti-slip pad 4. The anti-slip pad 4 can be made of silicone or rubber and can also be connected to the end of the counterweight 2 with adhesive to provide an anti-slip effect during use.

[0027] Specifically, in this embodiment, the base shell 1 has an inwardly folded edge 101 at the end near the opening, which is used to strengthen the structural strength of the base shell 1 at the end. It is understood that in other embodiments, the base shell 1 has a straight cylindrical structure at the end near the opening, that is, the structure without the folded edge 101 is designed.

[0028] Specifically, the anti-slip pad 4 has a first through hole 401 in the thickness direction, the counterweight 2 has a stepped hole 201 and a second through hole 202 in the thickness direction, and the base shell 1 has a third through hole 102 in the thickness direction. The first through hole 401, the stepped hole 201, the second through hole 202 and the third through hole 102 are coaxially arranged. The minimum inner diameter of the stepped hole 201 is larger than the inner diameter of the second through hole 202. The stepped hole 201 is close to one end of the first through hole 401, and the second through hole 202 is close to one end of the third through hole 102. They are mainly used to install support rods and lock the support rods with nuts. The nuts are accommodated in the stepped hole 201. To facilitate the installation and disassembly of the nuts, the stepped hole 201 has a conical structure.

[0029] Specifically, the first through hole 401 is located at the center of the counterweight base, which can further improve the stable support for the supported object and avoid the problem of poor counterweight effect caused by the center of gravity of the counterweight base shifting.

[0030] Specifically, the base shell 1 has a flange 103 extending toward the counterweight 2 at the third through hole 102. The flange 103 structure can further increase the bonding range with the counterweight 2 through the adhesive layer 3, and prevent the counterweight 2 from shifting radially relative to the base shell 1.

[0031] Specifically, the counterweight 2 is a cement mixture, which can be formed by casting, or the counterweight 2 can be made of other materials, such as metal.

[0032] Specifically, the outer surface of the base shell 1 is provided with patterns, coatings or textures, so that different types of patterns, coatings or textures can be designed according to different actual needs to meet the needs of different occasions and different users.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
