Description
Technical Field
[0001] The utility model relates to the technical field of bolts and nuts, in particular to a bolt and nut anti-loosening clamping block. Background Technique
[0002] A bolt is a cylindrical threaded fastener used in conjunction with a nut. It is a type of fastener composed of two parts: a head and a screw rod (a cylinder with external threads). It needs to cooperate with a nut. A nut is a screw cap, a part that is screwed together with a bolt or a screw rod to play a fastening role. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). Bolts and nuts are used for fastening and connecting two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, bolt connection belongs to detachable connection.
[0003] However, after the bolt and nut fix the components, due to the influence of external vibration or the vibration of the components themselves on the bolt and nut, the bolt and nut rotate, resulting in the risk of loosening of the bolt and nut; therefore, it does not meet the existing requirements. For this reason, we propose a bolt and nut anti-loosening clamping block. Content of the Utility Model
[0004] The purpose of the utility model is to provide a bolt and nut anti-loosening clamping block to solve the problems mentioned in the above background technique, that is, after the bolt and nut fix the components, due to the influence of external vibration or the vibration of the components themselves on the bolt and nut, the bolt and nut rotate, resulting in the risk of loosening of the bolt and nut.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A bolt and nut anti-loosening clamping block, including a connecting bolt and a connecting nut. The connecting bolt is rotationally installed on the outside of the connecting bolt through threads. A bolt limiting plate is detachably installed on the outside of the connecting bolt. A nut limiting plate is detachably installed on the outside of the connecting nut. Both ends of the nut limiting plate and the bolt limiting plate are bent at 90 degrees. A plurality of positioning connecting plates are installed between the end of the nut limiting plate and the end of the bolt limiting plate. Positioning plugging blocks are fixed on the inner side of the end of the nut limiting plate and one end of the positioning connecting plate. Positioning sliding grooves are provided on the inner side of the end of the bolt limiting plate and the other end of the positioning connecting plate. The positioning plugging block is slidably clamped inside the positioning sliding groove.
[0006] Preferably, a round hole runs through the middle of the nut limiting plate, and the diameter of the round hole is larger than the maximum outer diameter dimension of the screw rod of the lamp source connecting bolt.
[0007] Preferably, anti - detachment springs are fixedly installed inside the ends of the nut limiting plate and one end of the positioning connecting plate. One end of each anti - detachment spring is fixedly connected with an anti - detachment limiting block, and the anti - detachment limiting block is slidably connected to the nut limiting plate or the positioning connecting plate.
[0008] Preferably, anti - detachment limiting grooves are provided at the other end of the positioning connecting plate and the end of the bolt limiting plate, and one end of the anti - detachment limiting block is inserted inside the anti - detachment limiting groove.
[0009] Preferably, two limiting metal plates are fixedly installed inside both ends of the nut limiting plate and the bolt limiting plate. The two limiting metal plates at the same end of the nut limiting plate and the bolt limiting plate are symmetrically arranged in a V - shape with respect to each other.
[0010] Preferably, an elastic connecting strip is fixedly connected between the two limiting metal plates that are symmetrically arranged in a V - shape, and the elastic connecting strip is a rubber band.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. The present utility model connects the nut limiting plate and the bolt limiting plate by using multiple mutually spliced positioning connecting plates, so that the nut limiting plate and the bolt limiting plate are respectively in close contact with the connecting nut and the connecting bolt, ensuring that the connecting bolt and the connecting nut cannot move in the direction of their own axes. Moreover, by changing the number between the nut limiting plate and the bolt limiting plate, bolts and nuts of different lengths and sizes can be fixed, preventing the bolts and nuts from loosening after use and ensuring the structural stability of the bolts and nuts.
[0013] 2. The present utility model uses two limiting metal plates that are symmetrically arranged in a V - shape to position and squeeze the sides of the connecting bolt and the connecting nut, and applies a tensile force between the two limiting metal plates that are symmetrically arranged in a V - shape, so that the limiting metal plates apply a pressure to the connecting bolt and the connecting nut, ensuring that the connecting bolt and the connecting nut cannot rotate around the axis and ensuring the structural stability of the bolts and nuts.

Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0021] As Figures 1 to 3 shown, a bolt and nut anti-loosening clamping block includes a connecting bolt 1 and a connecting nut 2. The connecting bolt 1 is rotationally installed on the outside of the connecting bolt 1 through threads. A bolt limiting plate 5 is detachably installed on the outside of the connecting bolt 1. A nut limiting plate 4 is detachably installed on the outside of the connecting nut 2. Both ends of the nut limiting plate 4 and the bolt limiting plate 5 are bent at a right angle. A plurality of positioning connecting plates 6 are installed between the ends of the nut limiting plate 4 and the ends of the bolt limiting plate 5. Positioning plugging blocks 7 are fixed on the inner sides of the ends of the nut limiting plate 4 and one end of the positioning connecting plate 6. Positioning sliding grooves 8 are provided on the inner sides of the ends of the bolt limiting plate 5 and the other end of the positioning connecting plate 6. The positioning plugging blocks 7 are slidably clamped inside the positioning sliding grooves 8. The nut limiting plate 4 and the bolt limiting plate 5 are connected by a plurality of mutually spliced positioning connecting plates 6, so that the nut limiting plate 4 and the bolt limiting plate 5 are respectively closely attached to the connecting nut 2 and the connecting bolt 1, ensuring that the connecting bolt 1 and the connecting nut 2 cannot move in the direction of their own axes.
[0022] A circular hole runs through the middle of the nut limiting plate 4. The diameter of the circular hole is larger than the maximum outer diameter of the screw rod of the lamp source connecting bolt 1, ensuring the smooth assembly of the nut limiting plate 4 and the connecting nut 2, and the assembly process will not affect or interfere with the connecting bolt 1.
[0023] Anti-loosening springs 11 are fixed inside the ends of the nut limiting plate 4 and one end of the positioning connecting plate 6. Anti-loosening limiting blocks 10 are fixed at one ends of the anti-loosening springs 11. The anti-loosening limiting blocks 10 are slidably connected to the nut limiting plate 4 or the positioning connecting plate 6. Anti-loosening limiting grooves 9 are provided at the other end of the positioning connecting plate 6 and the ends of the bolt limiting plate 5. One end of the anti-loosening limiting block 10 is inserted inside the anti-loosening limiting groove 9. By inserting the anti-loosening limiting block 10 into the anti-loosening limiting groove 9, the positions of the positioning connecting plate 6 and the bolt limiting plate 5 are fixed, ensuring that the positioning connecting plate 6 and the nut limiting plate 4, the positioning connecting plate 6 and the positioning connecting plate 6, and the bolt limiting plate 5 and the positioning connecting plate 6 will not be separated.
[0024] As Figure 4 and Figure 5 shown, two limiting metal plates 12 are fixed to the inner sides of both ends of the nut limiting plate 4 and the bolt limiting plate 5. The two limiting metal plates 12 located at the same end of the nut limiting plate 4 and the bolt limiting plate 5 are symmetrically V-shaped with respect to each other. A elastic connection strip 3 is fixedly connected between the two limiting metal plates 12 that are symmetrically V-shaped. The elastic connection strip 3 is a rubber band. The sides of the connecting bolt 1 and the connecting nut 2 are positioned and squeezed by the two limiting metal plates 12 that are symmetrically V-shaped, ensuring that the connecting bolt 1 and the connecting nut 2 cannot rotate around the axis.
[0025] Working principle: First, connect the connecting bolt 1 and the connecting nut 2 and fix the installation components. Then, put the nut limiting plate 4 on the outside of the connecting bolt 1 and fit it to the connecting nut 2. Then, align the positioning connecting plate 6 with the nut limiting plate 4, and insert the end of the positioning connecting plate 6 into the inner side of the end of the nut limiting plate 4. When the positioning connecting plate 6 contacts the nut limiting plate 4, the anti-loosening limiting block 10 slidably installed inside the nut limiting plate 4 will be squeezed into the nut limiting plate 4 and the anti-loosening spring 11 will be compressed. After the positioning connecting plate 6 and the nut limiting plate 4 are completely connected, the anti-loosening spring 11 elastically resumes and pushes the anti-loosening limiting block 10 out of the nut limiting plate 4, so that the anti-loosening limiting block 10 fixes the position of the positioning connecting plate 6. Relying on the assembly of the positioning connecting plate 6 and the nut limiting plate 4, all the positioning connecting plates 6 are assembled at one time. Finally, connect the bolt limiting plate 5 to the last positioning connecting plate 6 and make the bolt limiting plate 5 fit the end face of the connecting bolt 1. The nut limiting plate 4 and the bolt limiting plate 5 are connected by a plurality of mutually spliced positioning connecting plates 6, so that the nut limiting plate 4 and the bolt limiting plate 5 are respectively in close contact with the connecting nut 2 and the connecting bolt 1, ensuring that the connecting bolt 1 and the connecting nut 2 cannot move in the direction of their own axes, avoiding loosening of the bolt and nut after use, and ensuring the structural stability of the bolt and nut.
