Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] The following describes in detail, with reference to the accompanying drawings, a nut structure provided by this utility model and its corresponding technical effects.

[0031] Please refer to Figures 1-3 The nut structure 1 provided in this embodiment includes a nut 200 and a mounting body 100. The nut 200 has a screw hole 210, and the nut 200 body is detachably mounted on the mounting body 100. The mounting body 100 has a through hole 101 for exposing the screw hole 210, and the mounting body 100 is used for detachable assembly with a connecting device. It should be noted that the connecting device can be understood as the structure in which the nut structure 1 is applied, that is, the application scenario of the connecting device.

[0032] Understandably, after the mounting body 100 is connected to the connecting device, the nut structure 1 installed on the mounting body 100 exposes the through hole 101 through the screw hole 210. When other connecting parts need to be connected to the connecting device, the connecting parts can be threadedly connected to the nut 200 by bolts, thereby connecting the connecting parts to the connecting device.

[0033] Understandably, since the nut 200 is detachably connected to the mounting body 100, when the threaded hole of the nut 200 is damaged, that is, when the threaded hole 210 of the nut 200 is damaged, only the nut 200 can be replaced, avoiding the need to replace the entire nut structure 1, thereby reducing costs.

[0034] When a threaded hole is provided on the mounting body 100, the susceptibility of the threaded hole to damage is not only affected by external torque, but also by the material of the mounting body 100. Therefore, if the external torque is too large and the material strength of the mounting body 100 is weak or the heat treatment of the threaded hole is improper, the thread of the threaded hole is prone to damage. In this embodiment, the nut 200 is detachably connected to the mounting body 100, and the nut 200 can be an existing nut 200, which avoids the situation where the threaded hole is damaged due to the weak material strength of the mounting body 100 and excessive external torque.

[0035] Some existing mounting bodies 100 have threaded holes for observation. Therefore, if the external torque is too high and the material strength of the mounting body 100 is weak or the heat treatment of the threaded hole is not done properly, the threaded hole is easily damaged. Therefore, the entire nut structure 1 must be replaced.

[0036] In detail, in this embodiment, the mounting body 100 has an assembly groove 110, and the nut 200 is detachably assembled into the assembly groove 110. The assembly groove 110 communicates with the through hole 101. It is understood that because the nut 200 is detachably installed in the assembly groove 110, the corrosion of the nut 200 due to external environmental influences can be reduced, thus improving the service life of the nut 200.

[0037] In this embodiment, the mounting body 100 has a first side 130 and a second side 140 opposite to each other in its thickness direction. The mounting groove 110 is located on the first side 130, and the through hole 101 is installed on the second side 140 of the mounting body 100. When the nut structure 1 is connected to the external connecting device, the first side 130 is closer to the connecting device than the second side 140.

[0038] The mounting body 100 has multiple mating holes 160, which are evenly spaced along the circumference of the through hole 101. The nut structure 1 also includes multiple fasteners 170 corresponding to each of the mating holes 160. The fasteners 170 are used to pass through the mating holes 160 and be fixedly connected to the connecting device. It can be understood that due to the arrangement of the fasteners 170 and the mating holes 160, the mounting body 100 can be stably mounted on the external connecting device.

[0039] In detail, in this embodiment, there are two mating holes 160. The two mating holes 160 are also arranged in the radial direction of the through hole 101. After the two fasteners 170 are respectively inserted into the mating holes 160 and installed on the connecting device, the two fasteners 170 can ensure that the mounting body 100 is relatively stably installed on the connecting device.

[0040] Fastener 170 can be a threaded fastener 170 or a snap-fit ​​fastener. In this embodiment, fastener 170 is a threaded fastener 170.

[0041] Understandably, after the nut 200 is fixedly installed in the mounting slot 110, the mounting body 100 can be connected to the external connecting device using the fastener 170. This allows the external connecting structure to be connected to the connecting device via the nut structure 1 in this application.

[0042] In detail, the assembly groove 110 includes an assembly end face 111 and an inner peripheral surface 112. The assembly end face 111 is provided with a through hole 101, that is, the through hole 101 penetrates the end face of the second side 140 of the mounting body 100 and the assembly end face 111 of the assembly groove 110.

[0043] Optionally, the inner circumferential surface 112 is adapted to the outer circumferential surface of the nut 200. Since the inner circumferential surface 112 of the mounting groove 110 is adapted to the outer circumferential surface of the nut 200, it can be understood that when the nut 200 is a hexagonal nut 200, the inner circumferential surface 112 of the mounting groove 110 has a hexagonal inner surface adapted to the outer circumferential surface of the hexagonal nut 200. After the nut 200 is installed in the mounting groove 110, the six faces of the nut 200 abut against the inner circumferential surface 112 of the mounting groove 110 respectively, so as to ensure that the nut 200 is relatively stably installed in the mounting groove 110 and reduce the situation where the nut 200 moves radially in the mounting groove 110.

[0044] In detail, the nut structure 1 also includes a pressure block 300, and the mounting body 100 has a pressure groove 120. The pressure groove 120 is located on the side of the assembly groove 110 away from the through hole 101 and is connected to the assembly groove 110. It can be understood that the pressure groove 120 is closer to the first side 130 of the mounting body 100 relative to the assembly groove 110.

[0045] The pressure block 300 is detachably installed in the pressure groove 120 to facilitate the replacement of the nut 200 by the operator. The pressure block 300 is used to press the nut 200 into the assembly groove 110. The pressure block 300 exposes the relief opening 320 of the screw hole 210 so that it can be screwed into the screw hole 210 of the nut 200 from the outside by bolts.

[0046] Understandably, after the pressure block 300 is fixedly installed in the pressure groove 120, the pressure block 300 can press the nut 200 into the assembly groove 110. That is, at this time, the two ends of the nut 200 in the axial direction respectively abut against the pressure block 300 and the assembly end face 111. After being pressed by the pressure block 300, the nut 200 is stably assembled in the assembly groove 110 and will not move relative to the assembly groove 110, which facilitates connection with the external connection structure by bolts.

[0047] The axial dimension of the pressure groove 120 is greater than or equal to the thickness of the pressure block 300. That is, when the pressure block 300 is installed in the pressure groove 120, the pressure block 300 will not protrude from the pressure groove 120, so as to ensure stable assembly of the mounting body 100 with the connecting device.

[0048] The end face of the pressure groove 120 is provided with a first mounting hole 121, and the pressure block 300 is provided with a second mounting hole 310 corresponding to the first mounting hole 121. The nut structure 1 also includes a connector 400, which passes through the second mounting hole 310 and is threadedly connected to the first mounting hole 121. That is, the connector 400 is a threaded fastener 170, and the first mounting hole 121 is a threaded hole. Therefore, after the connector 400 installs the pressure block 300 on the mounting body 100, the pressure block 300 presses against the side of the nut 200 away from the assembly end face 111, so that the nut 200 is fixedly installed in the assembly groove 110.

[0049] There are multiple pressure grooves 120 and multiple pressure blocks 300. The multiple pressure grooves 120 are arranged at intervals along the circumference of the assembly groove 110. The pressure blocks 300 are pressed onto the end of the nut 200 away from the through hole 101 and are all located outside the screw hole 210. It can be understood that since the multiple pressure grooves 120 are arranged at intervals along the circumference of the assembly groove 110, it is convenient for the multiple pressure blocks 300 to press the nut 200 relatively evenly, so that the end face of the nut 200 away from the through hole 101 receives the pressing force of the pressure block 300 relatively stably.

[0050] In detail, in this embodiment, there are two pressure grooves 120, and the two pressure grooves 120 are evenly spaced along the circumference of the assembly groove 110.

[0051] The pressure block 300 has a recess on the side away from the first mounting block. The axial dimension of the head of the connector 400 is less than or equal to the axial dimension of the recess. That is, after the connector 400 passes through the second mounting hole 310 and is screwed into the first mounting hole 121, the head of the connector 400 will not protrude out of the recess, ensuring the flatness of the first side 130 of the mounting body 100, so that the mounting body 100 can be more stably assembled on the external connecting device.

[0052] Optionally, a stepped groove 150 is provided on the outer side of the mounting body 100. Understandably, the stepped groove 150 on the outer side of the mounting body 100 facilitates the handling by operators.

[0053] In summary, this utility model embodiment provides a nut structure 1 including a nut 200 and a mounting body 100. The nut 200 has a threaded hole 210, and the nut 200 body is detachably mounted on the mounting body 100. The mounting body 100 has a through hole 101 for exposing the threaded hole 210, and the mounting body 100 is used for detachable assembly with a connecting device. Because the nut 200 and the mounting body 100 are detachably connected, when the threaded hole of the nut 200 is damaged, that is, when the threaded hole 210 of the nut 200 is damaged, only the nut 200 can be replaced, avoiding the need to replace the entire nut structure 1, thereby reducing costs.
