At present, commonly used reed nuts include U-shaped reeds, with a through hole set on the reed and a nut set on one side of the reed, and the inner hole of the nut is coaxial with the through hole. The nut is generally welded to the reed, but since the reed is easily deformed during welding, the inner hole of the nut is often not coaxial with the through hole, and it cannot be corrected or repaired after welding, resulting in a poor product qualification rate. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a reed nut with a higher production qualification rate.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a reed nut, comprising a first reed, a second reed and a nut, wherein the first reed and the second reed are parallel to each other, and one end of the first reed is connected to one end of the second reed through an arc-shaped connecting piece, the first reed is provided with a first through hole, and the second reed is provided with a second through hole,

[0005] The outer side wall of the nut is provided with a plurality of protrusions, and the protrusions are provided with connecting holes axially penetrating the nut. A plurality of connecting columns are fixedly provided on the side of the first spring sheet away from the second spring sheet, and each connecting column penetrates a connecting hole. A threaded section is provided at one end of the connecting column away from the first spring sheet, and a locking block threadably matched with the threaded section is provided on the threaded section; the inner hole of the nut, the first through hole and the second through hole are coaxially arranged.

[0006] Furthermore, the height of the protrusion is smaller than the height of the nut, and the locking block is located on the upper end surface of the protrusion.

[0007] Furthermore, the connecting column is connected to the first spring sheet by welding.

[0008] Furthermore, there are three protrusions, three connection holes and three connection columns.

[0009] Furthermore, the diameters of the first through hole and the second through hole are larger than the inner diameter of the nut.

[0010] The beneficial effect of the utility model is that when producing the reed nut of the utility model, the connecting column is fixed to the first reed, and then the connecting hole on the nut is aligned with the connecting column, and the nut is moved so that the connecting column passes through the connecting hole, and then the locking block is connected to the connecting column, and the locking block can press and fix the nut to the first reed. In the utility model, the nut and the reed do not need to be connected by welding, and the assembly is simpler. At the same time, the deformation of the reed during the welding process can be avoided, thereby ensuring that the first through hole, the second through hole and the inner hole of the nut are in a coaxial state, and improving the qualified rate of the product.

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] The reed nut of the utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a first reed 1, a second reed 2 and a nut 3. The first reed 1 and the second reed 2 are parallel to each other, and one end of the first reed 1 is connected to one end of the second reed 2 through an arc-shaped connecting piece 4. The first reed 1 is provided with a first through hole 5, and the second reed 2 is provided with a second through hole 6.

[0017] The first reed 1, the second reed 2 and the connecting piece 4 are made of a material with good elasticity and high strength, such as spring steel, etc. The first reed 1, the second reed 2 and the connecting piece 4 can be formed by bending a plate as a whole, and then a first through hole 5 is drilled on the first reed 1, and a second through hole 6 is drilled on the second reed 2.

[0018] The outer wall of the nut 3 is provided with a plurality of protrusions 7, and the protrusions 7 are provided with connecting holes 8 axially penetrating the nut 3. A plurality of connecting columns 9 are fixedly provided on the side of the first spring leaf 1 away from the second spring leaf 2. The diameter of the connecting column 9 is adapted to the diameter of the connecting hole 8. Each connecting column 9 penetrates a connecting hole 8. A threaded section is provided at one end of the connecting column 9 away from the first spring leaf 1, and a locking block 10 threadably matched with the threaded section is provided on the threaded section; the inner hole of the nut 3, the first through hole 5 and the second through hole 6 are coaxially arranged.

[0019] During production, the connecting column 9 is fixed to the first spring leaf 1. Specifically, the connecting column 9 can be welded to the first spring leaf 1. Compared with the nut 3, the connecting column 9 has a smaller diameter and a smaller connection range with the first spring leaf 1, so the deformation of the first spring leaf 1 during welding is also relatively small. Multiple connecting columns 9 are evenly distributed around the first through hole 5. Then, the connecting hole 8 of the nut 3 is aligned with the connecting column 9, and then the nut 3 is moved so that the connecting column 9 passes through the connecting hole 8. Finally, the locking block 10 is installed on the threaded section of the connecting column 9, and the nut 3 is pressed and fixed to the first spring leaf 1 by the locking block 10. After connection, the first through hole 5 and the inner hole of the nut 3 are connected. The locking block 10 can be a conventional small nut.

[0020] The utility model adopts the connection column 9 and the locking block 10 to fix the nut 3 and the first spring 1, replacing the traditional welding connection, which can avoid the first spring 1 from being greatly deformed during the welding process, ensure the position accuracy of the inner hole of the nut 3 and the first through hole 5, and reduce the defective rate of the product. In addition, the connection column 9 can also play a role in positioning the nut 3 to ensure the stability of the nut 3.

[0021] The height of the protrusion 7 is smaller than the height of the nut 3, and the locking block 10 is located on the upper end surface of the protrusion 7. After the locking block 10 is installed, the top surface of the locking block 10 is at the same height as the top surface of the nut 3, or the top surface of the locking block 10 is lower than the top surface of the nut 3, so as to avoid the top surface of the locking block 10 protruding, so that the shape of the reed nut is more regular, which is convenient for storage.

[0022] In the present invention, the number of the protrusions 7, the connection holes 8 and the connection posts 9 are all three, and may also be four, five or six.

[0023] When using the spring nut, the screw needs to first pass through the second through hole 6 and the first through hole 5 and then be threadedly connected to the nut 3. In order to facilitate the screw to first pass through the second through hole 6 and the first through hole 5, the diameters of the first through hole 5 and the second through hole 6 are larger than the inner diameter of the nut 3, that is, the diameters of the first through hole 5 and the second through hole 6 are larger than the diameter of the screw that matches the nut 3, so that the screw can pass through the first through hole 5 and the second through hole faster.

[0024] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
