Description

Technical Field

[0001] The utility model relates to the technical field of square nuts, in particular to a square locking nut with strong friction. Background Art

[0002] Square nut, also known as square nut, is a kind of hardware equipment and fastening accessories. It is square in shape, has internal threads, and can be used with bolts. Most of its materials are made of various embossed wires, the most common ones are lead brass, stainless steel, alloy and other materials.

[0003] In the installation of aluminum profile frames, square nuts are more commonly used. During installation, they need to be inserted into the groove of the aluminum profile frame or the inside of the slide rail in advance, and then used to connect various accessories. Since the slide rail or the groove can only accommodate nuts, and the umbrella of the bolt does not contact the slide rail in the direction of the groove when it is tightened on the slide rail, the bolt is very easy to loosen. Therefore, it is necessary to design a square locking nut with strong friction to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a square locking nut with strong friction.

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

[0006] A square locking nut with strong friction comprises a nut body, a threaded hole is formed on the nut body, a contact mechanism for contacting a bolt is provided on the nut body, the contact mechanism comprises a threaded barrel arranged on the nut body, a contact ring is provided on the threaded barrel, and a limiting mechanism for limiting the position of the threaded barrel is provided on the nut body.

[0007] Preferably, the limiting mechanism comprises a limiting cylinder fixedly connected to the upper end of the nut body, and the threaded cylinder is slidably connected to the limiting cylinder.

[0008] Preferably, a first anti-slip pad is provided at the upper end of the contact ring, and the cross-section of the first anti-slip pad is annular.

[0010] Preferably, a mounting ring is provided at the lower end of the nut body, and a side wall of the mounting ring is provided with an external thread.

[0011] The utility model has the following beneficial effects:

[0012] 1. The device is provided with a contact mechanism. By loosening the threaded barrel and the contact ring between the bolt and the nut body, the threaded barrel and the nut body form a double nut. Through the interaction between the two nuts, the friction between the thread pairs is increased to achieve locking, so that the block nut can also be locked in the application of aluminum profiles;

[0013] 2. The device is provided with a limiting mechanism, so that the threaded barrel can accurately position the threaded hole of the nut body, thereby improving the practicality of the device;

[0014] 3. The device is provided with a mounting ring, and the contact ring can be screwed onto the mounting ring during transportation, so that the nut body and the threaded barrel are connected as one, avoiding the loss of one of them, thereby improving the practicality of the device.

[0019] 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 of the embodiments.

[0020] Reference Figure 1-3 A square locking nut with strong friction includes a nut body 1, a threaded hole is opened on the nut body 1, a contact mechanism for contacting a bolt is provided on the nut body 1, and the contact mechanism includes a threaded barrel 2 arranged on the nut body 1, and a contact ring 5 is provided on the threaded barrel 2.

[0021] A limiting mechanism for limiting the position of the threaded barrel 2 is provided on the nut body 1 . The limiting mechanism includes a limiting barrel 4 fixedly connected to the upper end of the nut body 1 . The threaded barrel 2 is slidably connected to the limiting barrel 4 .

[0022] In the utility model, a first anti-skid pad 3 is provided at the upper end of the contact ring 5. The cross section of the first anti-skid pad 3 is annular, which can increase the friction coefficient with the upper end of the contact ring 5, making the bolt more difficult to rotate.

[0023] In the utility model, two installation grooves 7 are provided on the upper end of the nut body 1, and a second anti-slip pad 8 is arranged in the installation groove 7, so that the friction coefficient between the upper end of the nut body 1 and the top of the slide rail is increased, and it is not easy to move in the slide rail.

[0024] In the utility model, a mounting ring 6 is provided at the lower end of the nut body 1 , an external thread is provided on the side wall of the mounting ring 6 , and an internal thread is provided on the inner wall of the contact ring 5 , so that the contact ring 5 can be screwed onto the mounting ring 6 .

[0025] In the initial state, the nut body 1 and the like are not located in the slide rail (as shown in the figure), the threaded barrel 2 is separated from the nut body 1, and the bolt is taken out.

[0026] When in use, first screw the bolt onto the threaded barrel 2 so that the contact ring 5 contacts the inner top of the bolt (when the first anti-skid pad 3 does not exist, it is contacted by the first anti-skid pad 3 if it exists), then screw the bolt onto the nut body 1, the distance between the bolt umbrella and the nut body 1 is greater than the thickness of the slide rail, then put the nut body 1 into the slide rail and move it to a suitable position, then tighten the bolt so that the nut body 1 gradually moves upward to press against the inner top of the slide rail, and the tightening is completed. The threaded barrel 2 and the nut body 1 form a double nut structure, so that the block nut in the slide rail can also have locking ability;

[0027] During transportation, the threaded barrel 2 can be taken out from the limiting barrel 4, the contact ring 5 can be inverted, and the contact ring 5 can be screwed onto the mounting ring 6, so that the nut body 1 and the threaded barrel 2 are connected as a whole, avoiding the loss of one of them when they are placed separately and inverted.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and practical concept of the present invention, which should be covered by the protection scope of the present invention.
