AI Technical Summary
Existing sleeve-type lifting nails, which use threaded connections, suffer from problems such as wobbling and insufficient load-bearing capacity.
The design employs a snap-fit method, which connects the circular sleeve to the round steel by extruding it to form an annular groove and protrusions. This increases the contact area and stability, prevents shaking, and enhances the load-bearing capacity through the depth of the annular groove.
This improves the stability and load-bearing capacity of the sleeve hanger and reduces processing costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sleeve hanging nail technology, and more specifically, to a snap-fit sleeve hanging nail. Background Technology
[0002] Sleeve hangers are pre-embedded in concrete and then connected to the load-bearing object via threads. This allows for the installation of various electrical equipment on buildings. In existing technologies, sleeve hangers mostly use threaded connections. That is, a threaded rod with one protruding end is first pre-embedded in the concrete, and then a threaded sleeve is connected to the other end of the threaded rod. Various load-bearing objects are then connected to the threaded sleeve. However, there are some problems in its use. There is a gap between the threaded rod and the threaded sleeve connected by threads, which can easily cause the load-bearing object to shake. In addition, the weight that the threaded rod and the threaded sleeve can bear is relatively small, which poses a safety hazard. Utility Model Content
[0003] The purpose of this invention is to address the problems of easy shaking and low load-bearing capacity of threaded connections by designing a snap-fit sleeve hanger.
[0004] The technical solution of this utility model to achieve the above objectives is a snap-fit sleeve hanger, including a threaded sleeve, a circular sleeve integrally formed at the lower end of the threaded sleeve, a round steel inside the circular sleeve, a conical truncated platform integrally formed at the lower end of the round steel, a groove at the upper end of the round steel, and the circular sleeve fitting against the upper end of the round steel by compression.
[0005] Furthermore, the upper end of the round steel has multiple annular grooves.
[0006] Furthermore, after compression, the circular sleeve forms multiple annular protrusions inside that correspond to the annular grooves.
[0007] Furthermore, the outer side of the circular sleeve forms multiple raised edges after compression.
[0008] The beneficial effects of this utility model are as follows: The circular sleeve and the round steel are connected by extrusion. After extrusion, the circular sleeve can deform and multiple annular grooves are opened on the upper end of the round steel, which makes the circular sleeve form annular protrusions. This can ensure the fit between the round steel and the circular sleeve and prevent shaking. The depth of the annular grooves is much greater than the depth of the thread, so it can bear greater force. Moreover, the processing method of opening annular grooves on the round steel is simpler than the processing of threaded rods, which can save costs. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0017] This utility model provides, for example Figure 1-5 The shown is a snap-fit sleeve hanger, including a threaded sleeve 1, a circular sleeve 2 integrally formed at the lower end of the threaded sleeve 1, a round steel 3 inserted inside the circular sleeve 2, a conical platform 4 integrally formed at the lower end of the round steel 3, and a groove opened at the upper end of the round steel 3. The circular sleeve 2 is pressed to fit the upper end of the round steel 3.
[0018] The process of lifting the load using this device is as follows: When processing this sleeve lifting nail, first extend one end of the round steel 3 into the round sleeve 2, then use a hydraulic press or other mechanical equipment to squeeze the round sleeve 2, causing the round sleeve 2 to deform and fit against the upper end of the round steel 3. Then, the conical platform 4 and the round steel 3 are pre-embedded in the concrete. Finally, the load-bearing net is connected to the threaded sleeve 1, which can lift the load.
[0019] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 5 The round steel 3 has multiple annular grooves 5 on its upper end, which can fix the round steel on a lathe and process the annular grooves 5 by turning. The processing is simple and convenient, saving costs. In addition, the multiple annular grooves 5 can also increase the contact area with the circular sleeve 2, thereby increasing the load-bearing capacity.
[0020] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 4 After compression, the circular sleeve 2 forms multiple annular protrusions 6 inside that correspond to the annular grooves 5. The annular protrusions 6 fit into the annular grooves 5, which can prevent the circular sleeve 2 from shaking and increase stability.
[0021] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4 After being compressed, the outer side of the circular sleeve 2 forms multiple raised edges 7, which can be used to limit the circular sleeve 2, thereby preventing the circular sleeve 2 and the threaded sleeve 1 from rotating when the load is connected to the threaded sleeve 1.
[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
