Description

Technical Field

[0001] The utility model relates to the technical field of positioning nuts, in particular to a press-in self-locking positioning nut. Background Art

[0002] With the increasing number of high-rise buildings, the frequent high-altitude firefighting accidents in recent years have attracted increasing public attention. Currently, the telescopic arms used on aerial platform fire trucks generally come in two types: a curved arm structure and a telescopic cylinder structure. The curved arm structure has fewer sections, while the telescopic cylinder structure has more sections. Both types of telescopic arms are raised and lowered using hydraulic cylinders. Nylon sliders are installed between the inner and outer cylinders of the telescopic arm through positioning nuts.

[0003] However, the existing nylon slider installation positioning nut structure is relatively simple, the positioning nut generally does not have a self-locking structure, and long-term vibration can easily cause it to fall off, thereby affecting the safety of the positioning nut. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the positioning nuts proposed in the above background technology generally do not have a self-locking structure and are easily caused to fall off due to long-term vibration, and to propose a press-in self-locking positioning nut.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A press-in self-locking nut comprises a nut body, the top of the nut body is provided with an anti-rotation end, the bottom of the nut body is provided with an introduction end, a material collection groove is provided between the anti-rotation end and the introduction end, and the middle of the nut body is provided with a threaded hole.

[0007] Preferably, the inner diameter of the anti-rotation end is larger than the inner diameter of the introduction end.

[0008] Preferably, the collecting trough is ring-shaped.

[0009] Preferably, the outer portion of the anti-rotation end is an annular hexagonal configuration.

[0010] Preferably, the outer portion of the introduction end is circular.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the utility model, the anti-rotation end is provided so that tearing material will be generated when the positioning nut is pressed into the nylon slider, and the tearing material enters the material collecting groove, so that the positioning nut is tightened and fixed, thereby realizing the self-locking function. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 The utility model is a schematic diagram of a top view of a press-in self-locking nut.

[0015] In the figure: 1 anti-rotation end, 2 introduction end, 3 material collection trough, 4 threaded hole. DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-2 A press-in self-locking nut includes a nut body, a top of the nut body is provided with an anti-rotation end 1, the outer portion of the anti-rotation end 1 is an annular hexagonal setting, which is convenient for pressing the nut body, and can produce tearing material in the process of pressing the nylon slider;

[0018] In this embodiment, an introduction end 2 is provided at the bottom of the nut body, and the outer portion of the introduction end 2 is circular, which facilitates the nut body to be pressed into the nylon slider;

[0019] In this embodiment, the inner diameter of the anti-rotation end 1 is larger than the inner diameter of the introduction end 2. A material collecting groove 3 is provided between the anti-rotation end 1 and the introduction end 2. The material collecting groove 3 is annular and is used to collect the torn material and rotate to tighten it.

[0020] In this embodiment, a threaded hole 4 is provided in the middle of the nut body to facilitate fixing the nut body.

[0021] In this embodiment, by setting the anti-rotation end, the positioning nut will produce tearing material during the process of being pressed into the nylon slider, and the tearing material will enter the material collecting groove, so that the positioning nut is tightened and fixed, thereby realizing the self-locking function.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
