Description

Technical Field

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

[0002] A counterweight base is a basic support component widely used in daily life and public places. Its main function is to provide stable support for the upper components through its own weight, preventing tipping or swaying. In the present technology, counterweight bases are commonly used in devices such as table lamps, floor lamps, parasols, advertising display racks, simple guardrails, and directional signs. By setting a base structure with a certain weight at the bottom, the stability and safety of the overall structure are improved.

[0003] In existing counterweight base structures, the common installation method involves passing a rod-shaped support through the interior or central through-hole of the counterweight base from top to bottom, and then connecting it to the rod-shaped support with a nut at the bottom or inside of the counterweight base via threads. This fixes the rod-shaped support to the counterweight base. This structure typically requires inserting and aligning the rod-shaped support during assembly, and tightening the nut within a confined space. This means that both the rod-shaped support and the nut need to be operated simultaneously during assembly and disassembly, making the process cumbersome and inefficient, especially in applications requiring frequent installation or disassembly. Furthermore, when the counterweight base itself is heavy, additional tools or auxiliary supports are often needed when assembling or disassembling the nut, further increasing the difficulty of use and hindering rapid assembly and maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a base with a threaded structure to solve the problems mentioned in the background art, such as complicated installation steps, low assembly efficiency and inconvenience in disassembly when the existing counterweight base is fixedly connected to the rod-shaped support.

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

[0006] A threaded base includes:

[0007] The base shell is a shell structure with one end open, and the end face of the base shell away from the open end has an opening;

[0008] The counterweight filler is filled and fixedly installed in the inner cavity of the base shell;

[0009] The anti-loosening nut is fixed inside the counterweight filler, and the threaded hole of the anti-loosening nut is connected to the opening on the base shell so that the threaded hole is connected to the external space of the base shell.

[0010] Optionally, the anti-loosening nut has a stepped hole at one end near the opening of the base shell, and a baffle is folded axially at the end face of the base shell and located at the edge of the opening. The baffle extends into the stepped hole and fits against the inner wall of the stepped hole.

[0011] Optionally, one end of the anti-loosening nut is fitted against the inner end wall of the base housing.

[0012] Optionally, the outer wall of the lock nut has a limiting portion extending radially outward, configured to prevent the lock nut from detaching from the counterweight filler.

[0013] Optionally, the limiting part is formed in the opening direction away from the base shell, and the cross-section of the limiting part has a trapezoidal structure.

[0014] Optionally, the base housing has a folded portion formed by folding inward at the edge away from the open end.

[0015] Optionally, the cross-section of the folded portion has an arc-shaped structure.

[0016] Optionally, an anti-slip pad is fixed to the outer surface of the counterweight filler.

[0017] Optionally, the base shell has a circular structure.

[0018] Optionally, the anti-loosening nut is located at the center of the base housing.

[0019] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0020] This invention embeds an anti-loosening nut inside the counterweight filler, allowing the anti-loosening nut to act as a fastener for threaded connection with the rod-shaped support. This eliminates the need to completely pass the rod-shaped support through the counterweight base during installation, achieving a reliable threaded connection. This significantly simplifies the connection between the counterweight base and the rod-shaped support, eliminating the need for tools or lifting the counterweight base during installation, making it convenient and quick.

[0031] 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.

[0032] like Figure 1-4 As shown, a base with a threaded structure includes:

[0033] The base shell 1 is a shell structure with one end open. The end face of the base shell 1 away from the open end has an opening 101. The base shell 1 can be made of metal or plastic to meet the needs of different occasions.

[0034] The counterweight filler 3 is filled and fixed in the inner cavity of the base shell 1. The counterweight filler 3 is a cement mixture and is formed in the base shell 1 by casting. Before casting, the anti-loosening nut 2 is placed in the base shell 1. After casting is completed, the anti-loosening nut 2 can be fixed in the counterweight filler 3.

[0035] The anti-loosening nut 2 is fixed inside the counterweight filler 3, and the threaded hole 201 of the anti-loosening nut 2 is connected to the opening 101 on the base housing 1 so that the threaded hole 201 is connected to the external space of the base housing 1. With this arrangement, the rod-shaped support with external threads can be threadedly connected to the anti-loosening nut 2.

[0036] Specifically, the anti-loosening nut 2 has a stepped hole 203 at one end near the opening 101 of the base shell 1. A baffle 102, folded axially along the end face of the base shell 1 and located at the edge of the opening 101, extends into the stepped hole 203 and fits against the inner wall of the stepped hole 203. Before pouring the counterweight filler 3, the stepped hole 203 and the baffle 102 can be interlocked to radially position the anti-loosening nut 2, preventing movement during pouring. Even after pouring, the baffle 102 continues to radially position the anti-loosening nut 2.

[0037] Specifically, one end of the anti-loosening nut 2 (the end with the stepped hole 203) is in contact with the inner end wall of the base shell 1, which can be used to prevent cement mixture from entering the gap between the anti-loosening nut 2 and the base shell 1, and avoid the problem that the counterweight filler 3 has an unsatisfactory molding effect due to the gap being too small.

[0038] Specifically, the outer wall of the anti-loosening nut 2 has a limiting part 202 extending radially outward, which is configured to prevent the anti-loosening nut 2 from separating from the counterweight filler 3. This can prevent deformation of the base shell 1 caused by excessive force between the anti-loosening nut 2 and the end face of the base shell 1 during actual use.

[0039] Specifically, the limiting part 202 is formed in the direction away from the opening 101 of the base shell 1, and the cross-section of the limiting part 202 is trapezoidal. It is understood that in other embodiments, the cross-sectional shape of the limiting part 202 can also be designed as a rectangle, an arc, or other shapes. In this example, the limiting part 202 is continuously formed around the circumference of the anti-loosening nut 2, or it can be distributed at intervals on the outer wall of the anti-loosening nut 2.

[0040] Specifically, the outer shell of the base 1 is folded inward at the edge away from the open end to form a folded part 103. The cross-section of the folded part 103 is an arc-shaped structure, which is mainly used to prevent hand scratches when carrying the counterweight base, thus providing a safety protection effect.

[0041] Specifically, the outer surface of the counterweight filler 3 is fixed with an anti-slip pad 4. The anti-slip pad 4 is made of silicone or rubber and can come into contact with the ground or other flat surfaces during actual use to achieve the anti-slip function.

[0042] Specifically, the base shell 1 has a circular structure; it is understood that in other embodiments, the base shell 1 may be designed as a rectangle or other shapes.

[0043] Specifically, the anti-loosening nut 2 is located at the center of the base housing 1; it is understood that in other embodiments, the anti-loosening nut 2 can also be designed on one side of the base housing 1 to adapt to different counterweight situations.

[0044] Through the above structural design, in the actual assembly and disassembly process, the fixing operation can be completed simply by screwing the rod-shaped support into the base from the outside. This reduces cumbersome steps such as threading, alignment, and tightening the bottom nut, improving overall assembly efficiency. It is especially suitable for usage scenarios that require frequent installation or disassembly. At the same time, the anti-loosening nut 2 is embedded and fixed inside the counterweight filler 3, which helps to ensure connection stability and prevents loosening due to vibration or external forces during long-term use. Thus, while ensuring the stability of the counterweight base, it also improves the convenience and reliability of use.

[0045] 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.
