Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to an inserted flat nut. Background Art

[0002] A nut is a fixed part with a hole in the center and threads on the inner side of the hole. It is often used in combination with screws or bolts of appropriate sizes to tightly connect mechanical equipment. There are many types of nuts, such as cap nuts, barrel nuts, cage nuts, and inserted nuts, etc.

[0003] The existing inserted nut is inserted into a pre-drilled hole. The surface of the part of the nut inserted into the hole is provided with threads or protrusions that are stuck inside the hole, and it is combined with screws or bolts to achieve the tight connection of mechanical equipment. However, after long-term use of the existing inserted nut, the threads or protrusions on its surface will be worn flat, and when tightening the screw or bolt, the inserted nut will move along with it, and the screw or bolt cannot be tightened, resulting in problems such as low service life and easy occurrence of safety hazards. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides an inserted flat nut. By setting a cutting plane and an internal hexagonal groove on the base, an internal hexagon can be inserted into the internal hexagonal groove to assist in tightening, improving the service life and avoiding the problem of safety hazards.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] An inserted flat nut, comprising a body. One end of the body is provided with a base, and the other end is provided with a connection hole. An internal thread is provided in the connection hole. A cutting plane is provided on the outer surface of the body, and an internal hexagonal groove is provided on the side of the base away from the body; by setting a cutting plane and an internal hexagonal groove on the base, an internal hexagon can be inserted into the internal hexagonal groove to assist in tightening, improving the service life and avoiding the problem of safety hazards.

[0007] As a preferred solution, the cutting plane is parallel to the central axis of the connection hole.

[0008] As a preferred solution, the number of the cutting planes is two, and the two cutting planes are symmetrically arranged.

[0009] As a preferred solution, the distance between the cutting planes is 5.95 cm - 6.15 cm.

[0010] As a preferred solution, the diameter of the connection hole is 5 cm.

[0011] As a preferred solution, the central axis of the internal hexagonal groove and the central axis of the connection hole are coaxial.

[0012] As a preferred solution, the depth of the hexagonal socket is 3.00 cm - 3.40 cm.

[0013] As a preferred solution, the diameter of the hexagonal socket is 4.02 cm - 4.08 cm.

[0014] As a preferred solution, the length of the body is 16.60 cm - 17.00 cm.

[0015] As a preferred solution, the diameter of the base is 10.80 cm - 11.20 cm.

[0016] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically,

[0017] 1. By providing a tangent plane on the surface of the body, compared with the prior art of providing threads or protrusions on the surface of the insert nut, the tangent plane is more practical and is not easily worn, which can improve the service life of the insert nut;

[0018] 2. By providing a hexagonal socket on the base, in actual use, when the tangent plane is worn flat and the insert nut moves with the screw or bolt, an external hexagonal tool can be inserted into the hexagonal socket to assist in tightening or releasing the tightened state, improving the service life of the insert bolt and reducing the occurrence of potential safety hazards.

[0026] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] As Figures 1-3 shown, the present utility model discloses an insert type flat nut, which includes a body 20. One end of the body 20 is provided with a base 10, and the other end is provided with a connection hole 21. An internal thread 22 is provided in the connection hole 21. A flat surface 23 is provided on the outer surface of the body 20. An internal hexagonal groove 11 is provided on the side of the base 10 away from the body 20. By providing the flat surface 23 and the internal hexagonal groove 11 on the base 10, an internal hexagon can be inserted into the internal hexagonal groove 11 to assist in tightening, improving the service life and avoiding potential safety hazards.

[0029] The flat surface 23 is parallel to the central axis of the connection hole 21. The number of the flat surfaces 23 is two, and the two flat surfaces 23 are symmetrically arranged. The flat surfaces 23 can slow down the speed of being worn flat and improve the service life.

[0030] It should be understood that the flat surface 23 can also be provided as a single one or multiple ones.

[0031] The distance between the flat surfaces 23 is 6.05 cm.

[0032] The diameter of the connection hole 21 is 5 cm.

[0033] The central axis of the internal hexagonal groove 11 is coaxial with the central axis of the connection hole 21.

[0034] The depth of the internal hexagonal groove 11 is 3.20 cm.

[0035] The diameter of the internal hexagonal groove 11 is 4.00 cm.

[0036] The length of the body is 16.80 cm.

[0037] The diameter of the base is 11.00 cm.

[0038] The usage method of the utility model: Insert the nut into the pre-set hole, align the bolt with the connection hole 21 and insert it while rotating and tightening. When the inserted hole is too large, an internal hexagon tool can be inserted into the internal hexagon groove 11, and during the process of rotating the bolt, the internal hexagon tool is used for reverse rotation or fixation to smoothly fix the bolt.

[0039] In summary, by setting a tangent plane 23 on the surface of the body 20, the utility model is more practical than the existing method of setting threads or protrusions on the surface of the insert nut, and it is not easily worn, which can improve the service life of the insert nut; by setting an internal hexagon groove 11 on the base 10, when the tangent plane 23 is worn flat or the hole diameter becomes larger during actual use, the insert nut moves with the screw or bolt, and an external internal hexagon tool can be inserted into the internal hexagon groove 11 for auxiliary tightening or releasing the tightened state, improving the service life of the insert bolt and reducing the occurrence of potential safety hazards.

[0040] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made to the above embodiments according to the technical reality of the utility model still fall within the scope of the technical solution of the utility model.
