Description

Technical Field

[0001] The utility model relates to the technical field of nuts for connecting steel structures, in particular to a positioning locking nut for connecting steel structures. Background Art

[0002] Steel structure connection nuts are fasteners used to connect different parts in steel structures. They are usually made of metal and have internal threads that can mate with external threads to ensure the stability of the connection. In steel structures, nuts are often used together with bolts. By tightening the bolts and nuts, the connection is strengthened to ensure the safety and stability of the structure.

[0003] The existing steel structure connection nut has a single structure and is easily loosened when subjected to external vibration during use, thereby reducing the connection tightness of the steel structure. In view of this, we propose a positioning locking nut for steel structure connection. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to actual needs, and provide a positioning locking nut for steel structure connection to solve the technical problem that the current existing steel structure connection nut has a single structure and is easily loosened by external vibration during use, thereby reducing the connection tightness of the steel structure.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: designing a positioning locking nut for steel structure connection, comprising a steel structure connection nut body, a plurality of locking components are evenly arranged inside the steel structure connection nut body, and an auxiliary component is provided outside the steel structure connection nut body;

[0006] The locking assembly includes a limiting groove, and several limiting grooves are evenly opened inside the steel structure connecting nut body. A movable ball is clamped inside the limiting groove, a locking rod is fixedly connected to the surface of the movable ball, and a spring is sleeved on the outside of the locking rod.

[0007] Preferably, two-thirds of the movable balls are engaged in the limiting groove, and the limiting groove and the steel structure connecting nut body are integrally formed.

[0008] Preferably, the movable ball forms an elastic structure through a spring and a limiting groove, and the end of the locking rod away from the movable ball is in the shape of a regular quadrangular pyramid.

[0009] Preferably, the steel structure connecting nut body includes a nut main body, and an auxiliary frame is fixed to the top of the nut main body.

[0010] Preferably, the auxiliary component includes a limiting ring frame, which is screwed to the outside of the auxiliary frame, and a number of convex strips are evenly distributed on the outside of the limiting ring frame. A movable frame is provided on the outside of the bottom of the limiting ring frame, and a card slot is provided on the inside of the top of the movable frame. A number of triangular grooves are evenly provided on the inner wall of the movable frame.

[0011] Preferably, the bottom of the limiting ring frame is matched and engaged with the inner slot of the movable frame, and the outer wall of the nut body is in contact with the inner wall of the movable frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model effectively squeezes the exposed part of the movable ball slowly into the limit groove through the downward movement of the auxiliary component. At this time, the movable ball drives the locking rod to move, so that the tip part of the locking rod moves out and embeds into the bolt surface, effectively realizing the locking between the steel structure connection nut body and the bolt, and improving the connection tightness. When the steel structure connection nut body needs to be disassembled, the auxiliary component is first moved upward. At this time, the movable ball part pops out under the influence of the spring rebound force, and the locking rod is moved into the limit groove as a whole, releasing the locking between the steel structure connection nut body and the bolt, and facilitating the disassembly of the steel structure connection nut body.

[0014] 2. In the present invention, when the steel structure connecting nut body is connected to the bolt, the rotating limit ring frame drives the movable frame to move downward. At this time, the triangular groove on the inner wall of the movable frame gradually squeezes the movable ball until it is completely squeezed into the limit groove, which makes it easier for the locking assembly to realize the locking function. The setting of the convex strip increases the contact friction, making it easier for the operator to screw the limit ring frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0025] A positioning lock nut for steel structure connection, see Figures 1 to 5 , including a steel structure connection nut body 1, a plurality of locking components 2 are evenly arranged inside the steel structure connection nut body 1, and an auxiliary component 3 is provided outside the steel structure connection nut body 1;

[0026] The locking assembly 2 includes a limiting groove 201, and several limiting grooves 201 are evenly arranged inside the steel structure connecting nut body 1. A movable ball 202 is engaged inside the limiting groove 201, among which two-thirds of the movable balls 202 are engaged inside the limiting groove 201. The limiting groove 201 and the steel structure connecting nut body 1 are integrally formed. A locking rod 203 is fixedly connected to the surface of the movable ball 202, and a spring 204 is provided on the outside of the locking rod 203. Furthermore, the movable ball 202 forms an elastic structure with the limiting groove 201 through the spring 204, and the end of the locking rod 203 away from the movable ball 202 is in the shape of a regular quadrangular pyramid. The utility model effectively squeezes the exposed part of the movable ball 202 slowly into the interior of the limiting groove 201 by moving the auxiliary component 3 downward. At this time, the movable ball 202 drives the locking rod 203 to move, so that the tip part of the locking rod 203 moves out and embeds into the bolt surface, effectively realizing the locking between the steel structure connecting nut body 1 and the bolt, and improving the connection tightness. When the steel structure connecting nut body 1 needs to be disassembled, the auxiliary component 3 is first moved upward. At this time, the movable ball 202 is partially popped out by the influence of the rebound force of the spring 204, and the locking rod 203 is moved into the interior of the limiting groove 201 as a whole, releasing the locking between the steel structure connecting nut body 1 and the bolt, and facilitating the disassembly of the steel structure connecting nut body 1.

[0027] It is worth noting that the steel structure connecting nut body 1 includes a nut body 101, an auxiliary frame 102 is fixedly connected to the top of the nut body 101, and the auxiliary component 3 includes a limiting ring frame 301, the limiting ring frame 301 is screwed to the outside of the auxiliary frame 102, and a number of protrusions 302 are evenly distributed on the outside of the limiting ring frame 301, a movable frame 303 is provided on the outside of the bottom of the limiting ring frame 301, and a slot 304 is provided on the inner side of the top of the movable frame 303, wherein the bottom of the limiting ring frame 301 is matched and engaged with the inner slot 304 of the movable frame 303, the outer wall of the nut body 101 is in contact with the inner wall of the movable frame 303, and the inner wall of the movable frame 303 is evenly provided with a number of triangular grooves 305. In the present invention, when the steel structure connecting nut body 1 is connected to the bolt, the rotating limiting ring frame 301 drives the movable frame 303 to move downward. At this time, the triangular groove 305 on the inner wall of the movable frame 303 gradually squeezes the movable ball 202 until it is completely squeezed into the limiting groove 201, which makes it easier for the locking assembly 2 to achieve the locking function. The setting of the convex strip 302 increases the contact friction, making it easier for the operator to screw the limiting ring frame 301.

[0028] When the bolt 201 is unlocked, the locking rod 203 is unlocked and the locking rod 203 is unlocked, so that the locking rod 203 is unlocked and the locking rod 203 is unlocked.
