Description

Technical Field

[0001] The utility model relates to the technical field of assembly equipment, in particular to a long handle fixing rod. Background Art

[0002] Screws and nuts are commonly used connectors in industrial production. They are easy and quick to install and can firmly connect various parts, components or structures together.

[0003] The screw and the nut are tightened by threads. The frictional force of the inclined plane between the threads will cause relative movement resistance between the two, generating a fastening force between the screw and the nut to clamp the parts between the screw and the nut. In the actual use process, the screw and the nut need to be respectively arranged on two sides of the part. The nut is arranged on the side away from the operator, and then the screw is screwed in from the front. After the screw passes through the part, it is screwed into the nut to complete the connection. When encountering a relatively narrow installation space, it is difficult to enter the installation space, and it is not convenient to fix the nut at the preset installation position, making the installation work difficult to carry out.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0005] Aiming at the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a long handle fixing rod for installing screws and nuts in a narrow space.

[0006] The technical solution of the present utility model is as follows:

[0007] A long handle fixing rod, comprising: a rod body; a support plate connected to the rod body, a limiting groove for accommodating a nut is formed on the support plate, the inner wall of the limiting groove fits at least two sides of the nut, and the limiting groove is arranged along the axial direction of the rod body; a pressing plate slidably arranged on the rod body, a U-shaped groove aligned with the limiting groove is formed on the pressing plate along the axial direction of the rod body; an elastic member arranged on the side of the pressing plate away from the support plate; one end of the elastic member is connected to the rod body, and the other end of the elastic member is connected to the pressing plate; wherein, the limiting groove faces the pressing plate, and the elastic member is in a compressed state.

[0008] The beneficial technical effects of the present utility model are as follows:

[0009] (1) In the long handle fixing rod of the present utility model, a support plate and a pressing plate are provided on the rod body. The support plate and the pressing plate are used to clamp the stacked nuts, spring washers and washers, and then the nuts, spring washers and washers can be easily moved to the preset nut connection position through the rod body. At the same time, an elastic member is provided, and a limiting groove is provided on the support plate. The elastic member in the compressed state drives the support plate and the pressing plate to fit together to clamp the nuts, spring washers and washers. Thanks to the long handle rod body, it can extend into a narrow area and send the nuts to positions that are difficult for the operator to reach, facilitating the operator to assemble screws and nuts.

[0010] (2) Further, the pressing plate is sleeved on the rod body through a polygonal limiting hole and cooperates with the polygonal surface of the rod body. The polygonal surface and the polygonal limiting hole limit the rotation of the pressing plate relative to the rod body, increasing the clamping stability of the pressing plate and the support plate.

[0011] (3) Further, a positioning ring is provided between the elastic member and the positioning pin to prevent the elastic member from being damaged due to the small contact area with the positioning pin. The positioning ring increases the force transmission area of the elastic member and prolongs the service life of the elastic member. Description of the Drawings

[0018] Figure 1 The schematic three-dimensional structure diagram of the long handle fixing rod of the present utility model in the clamped state is shown. Please refer to Figure 1 , a long handle fixing rod, which includes: a rod body 1, a support plate 2, a pressing plate 3 and an elastic member 4. The support plate 2 is connected to the rod body 1. A limiting groove 21 for accommodating a nut is provided on the support plate 2. The inner wall of the limiting groove 21 abuts at least two sides of the nut. The limiting groove 21 is arranged along the axial direction of the rod body 1. While clamping the nut into the limiting groove 21 to limit the position of the nut, the rotation of the nut is restricted, ensuring that the nut is fixed and facilitating the screwing of the screw into the nut. The pressing plate 3 is slidably arranged on the rod body 1. Along the axial direction of the rod body 1, a U-shaped groove 32 aligned with the limiting groove 21 is provided on the pressing plate 3. The U-shaped groove 32 allows the screw to pass through. The superposed nut, spring washer and gasket are clamped by the support plate 2 and the pressing plate 3, and then the nut, spring washer and gasket can be easily moved to the preset nut connection position through the rod body 1. The elastic member 4 is arranged on the side of the pressing plate 3 away from the support plate 2. One end of the elastic member 4 is connected to the rod body 1, and the other end of the elastic member 4 is connected to the pressing plate 3. Among them, the limiting groove 21 faces the pressing plate 3, and the elastic member 4 is in a compressed state. The elastic member 4 pushes the pressing plate 3 to slide towards the support plate 2 to automatically clamp the nut, spring washer and gasket arranged between the support plate 2 and the pressing plate 3.

[0019] The specific structures of the rod body 1 and the positioning ring 41 are described as follows:

[0020] Figure 2 The schematic front view structure diagram of the long handle fixing rod of the present utility model in the state where the pressing plate and the support plate are opened is shown. Please refer to Figure 2 , the cross-section of the rod body 1 is polygonal. Correspondingly, the pressing plate 3 is sleeved on the rod body 1 through a polygonal limiting hole. For example, the cross-section of the rod body 1 can be hexagonal, and at this time the rod body 1 is a hexagonal bar. The hexagonal cross-section of the hexagonal bar can provide better structural stability. The hexagonal cross-section makes it easier to clamp and process. At the same time, compared with circular materials, a larger cross-sectional size can be provided under the same cross-sectional area. The pressing plate 3 is sleeved on the rod body 1 through a polygonal limiting hole, ensuring that the pressing plate 3 will not rotate relative to the rod body 1.

[0021] At this time, a cylindrical section 11 is provided on the rod body 1, and the cross-section of the cylindrical section 11 is circular. The pressing plate 3 is toggled so that the pressing plate 3 slides onto the cylindrical section 11, and then the pressing plate 3 can be rotated around the rod body 1. After the screw is initially screwed into the nut, the operator pushes the rod body 1 towards the supporting plate 2. At this time, the movement of the pressing plate 3 is restricted by the nut, and the pressing plate 3 slides along the rod body 1 to the cylindrical section 11. The operator rotates the rod body 1, and the positions of the pressing plate 3 and the supporting plate 2 can be staggered. This facilitates the subsequent independent fixing of the nut by the supporting plate 2. After the screw is tightened, the gasket abuts against the installation plane.

[0022] Please refer to Figure 1 and Figure 2 , a positioning pin 5 is provided on the rod body 1, and the positioning pin 5 is arranged perpendicular to the axial direction of the rod body 1. The elastic member 4 is sleeved on the rod body 1, and the positioning pin 5 abuts against the elastic member 4. The relative positions of the elastic member 4 and the rod body 1 are fixed by the positioning pin 5, and the positioning pin 5 serves as a support point for the elastic member 4 to support the elastic member 4 to push the pressing plate 3. A positioning ring 41 is arranged between the elastic member 4 and the positioning pin 5, and the positioning ring 41 is sleeved on the rod body 1. The force transmission area of the elastic member 4 is increased through the positioning ring 41, and the service life of the elastic member 4 is extended.

[0023] The specific structures of the supporting plate 2 and the pressing plate 3 are described as follows:

[0024] Please refer to Figure 2 , the pressing plate 3 is bent towards the supporting plate 2 to form a bent portion 31, so that the pressing plate 3 at the U-shaped groove 32 is close to the supporting plate 2. Ensure that the pressing plate 3 and the supporting plate 2 can clamp the stacked nuts, spring washers and gaskets. A U-shaped groove 32 is also provided on the supporting plate 2, and the U-shaped groove 32 on the supporting plate 2 and the U-shaped groove 32 on the pressing plate 3 are coaxially arranged, so that when the nut is fixed by the supporting plate 2, the screw can pass through the supporting plate 2 to tighten the screw and the nut. An extension portion 22 is provided on the supporting plate 2, and the extension portion 22 is perpendicular to the rod body 1. The surface of the extension portion 22 close to the pressing plate 3 is at the same height as the surface of the supporting plate 2 close to the pressing plate 3. When the supporting plate 2 and the pressing plate 3 are attached, the contact surface between the two is increased to enhance stability.

[0025] Please refer to Figure 2 , the supporting plate 2 and the pressing plate 3 are perpendicular to the axial direction of the above-mentioned rod body 1. When fixing the nut, the operator can pull the rod body 1 perpendicular to the installation plane to make the supporting plate 2 or the pressing plate 3 fit the installation plane, which is convenient for operation. Among them, the supporting plate 2 is arranged at the end of one end of the rod body 1 to make the most of the length of the rod body 1.

[0026] The specific working process of the present utility model is as follows:

[0027] The operator toggles the pressure plate 3 away from the side of the pallet 2, stacks the nut, spring washer, and gasket in sequence between the pallet 2 and the pressure plate 3, with the gasket fitting against the pressure plate 3. Then, the operator stops toggling the pressure plate 3, and the elastic member 4 pushes the pressure plate 3 towards the pallet 2, and the pressure plate 3 and the pallet 2 clamp the stacked nut, spring washer, and gasket. At the end of the clamping rod body 1 away from the pallet 2, the rod body 1 is extended towards the installation position of the nut until the side of the pressure plate 3 away from the pallet 2 fits against the installation plane, which is the installation plane facing away from the operator. At this time, the U-shaped groove 32 on the pressure plate 3 aligns with the screw installation hole (not shown in the figure) on the installation plane. A screw is screwed in from the plane facing the operator, and the screw passes through the installation plane, gasket, and spring washer and then is screwed into the nut. At this time, the operator pushes the rod body 1, and the rod body 1 moves away from the operator. At this time, the screw restricts the position of the nut, and the nut restricts the movement of the pressure plate 3, causing the pressure plate 3 to slide along the rod body 1 until the pressure plate 3 slides to the cylindrical section 11 and the nut slides out of the limit groove 21, and the operator rotates the rod body 1. At this time, the screw abuts against the side of the U-shaped groove 32 on the pressure plate 3, restricting the rotation of the pressure plate 3, and the pressure plate 3 and the pallet 2 are misaligned. Along the opening direction of the U-shaped groove 32, the pressure plate 3 is removed from the gasket and the installation plane. Then, the nut is aligned with the limit groove 21, and the nut is reinserted into the limit groove 21. At this time, the pressure plate 3 and the pallet 2 are misaligned, and the pressure plate 3 does not enter between the gasket and the installation plane. The screw is tightened continuously until the screw and the nut are completely fastened, and the long handle fixing rod is removed from the installation position to complete the installation of the nut.

[0028] It can be seen that for the above-mentioned long handle fixing rod, the pallet 2 and the pressure plate 3 clamp the stacked nut, spring washer, and gasket, and then the nut, spring washer, and gasket can be easily moved to the preset nut connection position through the rod body 1. Thanks to the long handle of the rod body 1, it can extend into a narrow area and send the nut to a position that is difficult for the operator to reach, facilitating the operator to assemble the screw and nut.

[0029] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0030] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
