Description

Technical Field

[0001] This utility model belongs to the field of furniture accessories technology, and specifically relates to a lock nut that is easy to install. Background Technology

[0002] During furniture assembly, two parts are usually fixed together using screws. This requires using a screwdriver to tighten the screws into the two parts for connection. However, this method is time-consuming and laborious. Some furniture requires consumers to assemble it themselves after purchase, which also causes inconvenience. Utility Model Content

[0003] This invention addresses the shortcomings of existing furniture installation methods that rely on screws by designing a lock nut that is easy to install. The lock nut is pre-fixed to one of the furniture components that need to be connected, and a corresponding connector is pre-fixed at the connection point of another component. During assembly, it can be easily and conveniently installed by simply tapping it together.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a lock nut that is easy to install includes a head and a tooth. The tooth is connected to the lower part of the head, and the tooth is provided with an external thread. The head and the tooth are hollow structures, and the center of the hollow structure is located at the center of the head and the tooth.

[0005] The outer periphery of both the head and the teeth is circular. The axis of the head coincides with that of the teeth, and the diameter of the head is larger than that of the teeth. The axis of the head passes through the center of the hollow structure.

[0006] The inner wall of the hollow structure is a cylindrical structure with multiple protrusions and extensions. The center of the cylindrical structure coincides with the center of the hollow structure. The protrusions and extensions are staggered. The protrusions are arc-shaped structures facing the center of the hollow structure, and the extensions are arc-shaped structures away from the center of the hollow structure. The center of the inscribed circle formed by the protrusions coincides with the center of the hollow structure, and the center of the circumscribed circle formed by the extensions coincides with the center of the hollow structure.

[0007] The number of protrusions is the same as the number of extensions, and the number of protrusions is 4-8.

[0008] The hollow structure is projected in the horizontal direction as a hexagonal star, and the outer perimeter of the hexagonal star is arc-shaped.

[0009] The lock nut obtained through the above technical solution, which is easy to install, has the following advantages:

[0010] By pre-installing the lock nut and its connector on the two furniture fittings that need to be connected, the two fittings can be installed by gently tapping them together. No tools are required, making it suitable for manual installation in the home. The operation is convenient and quick.

[0011] This avoids the unsightly appearance caused by exposed screws in traditional installation methods. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Unless otherwise defined, the technical terms used in the following embodiments have the same meaning as commonly understood by those skilled in the art to which this utility model pertains.

[0019] The present invention will be further explained below with reference to the embodiments and accompanying drawings. It should be understood that the present invention is not limited to the specific embodiments described.

[0020] like Figure 1 , Figure 2 As shown, this utility model proposes a lock nut that is easy to install, including a head 1 and a thread 2. The head 1 is connected to the thread 2 below. The thread 1 is provided with external threads. Both the head 1 and the thread 2 are hollow structures 3, and the center of the hollow structure 3 is located at the center of the head 1 and the thread 2. In use, the thread 2 of the lock nut is pre-installed on one of the components that need to be connected, and an insert such as an iron rod is pre-installed on the other component. The outer diameter of the iron rod is controlled so that the iron rod can be inserted into the hollow structure 3 and pressurized to the lock nut after being gently tapped, thus completing the assembly of the two components.

[0021] The outer periphery of both the head 1 and the tooth 2 is circular. The axis of the head 1 and the tooth 2 coincides, and the diameter of the head 1 is larger than the diameter of the tooth 2. The axis of the head 1 passes through the center of the hollow structure 3.

[0022] like Figure 3 As shown, the inner wall of the hollow structure 3 is a cylindrical structure with multiple protrusions 31 and extensions 32. The center of the cylindrical structure coincides with the center of the hollow structure 3. The protrusions 31 and extensions 32 are staggered. The protrusions 31 are arc-shaped structures facing the center of the hollow structure, and the extensions 32 are arc-shaped structures away from the center of the hollow structure 3. The center of the inscribed circle formed by the protrusions 31 coincides with the center of the hollow structure 3, and the center of the circumscribed circle formed by the extensions 32 coincides with the center of the hollow structure 3. By providing protrusions 31 and extensions 32, when the iron rod enters the hollow structure 3, it only contacts the protrusions 31, which effectively reduces friction and makes it easier for the iron rod to penetrate.

[0023] The number of protrusions 31 and extensions 32 is the same, and the number of protrusions 31 is 4-8.

[0024] like Figure 4 As shown, the horizontal projection of the hollow structure 3 is a hexagonal star, and the outer periphery of the hexagonal star is all arc-shaped.

[0025] Before leaving the factory, the lock nut is pre-installed on the accessory one that needs to be connected. The lock nut can be screwed in by pre-drilling holes, or the wooden accessory can be directly driven into the lock nut so that the thread 2 of the lock nut enters into the accessory one, while the head 1 remains on the surface of the accessory one. When installing the iron rod installed on the other accessory two that needs to be connected after leaving the factory, simply align the iron rod with the hollow structure 3 of the lock nut, and tap the other side of the accessory two to make the iron rod enter the hollow structure 3, thus completing the connection of the two accessories.

[0026] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
