Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts fastening technology, specifically relating to a nut locking structure for a horizontal stud. Background Technology

[0002] In industrial equipment such as diaphragm pumps, critical connection parts often use a combination of horizontal studs (or double-ended studs, stud bolts) and nuts for fastening. However, under long-term, harsh vibration conditions, the horizontal stud nut connection faces a common and persistent technical problem of loosening and failure. Horizontal stud nuts are prone to loosening under long-term vibration conditions, leading to connection failure. Traditional anti-loosening measures (such as spring washers and double nuts) have problems such as easy degradation and aging, and large space occupation. Utility Model Content

[0003] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a nut locking structure for horizontal studs. This invention offers excellent anti-loosening performance, is easy to install, and can solve the problem of nuts easily loosening under vibration.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] This utility model provides a nut locking structure for a horizontal stud, including a nut body. The nut body has a semi-through groove on its top side towards the center line. The nut body has a locking threaded hole extending through the semi-through groove to the bottom of the groove. A locking screw is installed in the locking threaded hole. After the locking screw is screwed into the locking threaded hole, it can press the end face of the nut body.

[0006] Furthermore, the depth of the semi-through groove exceeds the centerline position of the nut body.

[0007] Furthermore, the depth of the semi-through groove exceeds the centerline of the nut body by 10mm-15mm.

[0008] Furthermore, the width of the semi-through groove is 4mm-6mm.

[0009] The beneficial effects of this utility model.

[0010] This invention can achieve excellent anti-loosening performance and high reliability through torque pre-tightening combined with mechanical locking. It makes up for the problem of connection failure caused by nut aging. It does not require additional parts, occupies little space, and only requires removing the locking screw before disassembly. It is easy to install and disassemble and can be reused. Attached Figure Description

[0011] To make the technical problems solved, the technical solutions, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] As shown in the accompanying drawings, this embodiment provides a nut locking structure for a horizontal stud, including a nut body 1. A semi-through groove 2 is formed on the top of the nut body 1 from one side towards the centerline. The semi-through groove 2 extends radially and partially disrupts the internal thread of the nut body 1. The depth of the semi-through groove 2 exceeds the centerline of the nut body 1. To ensure sufficient disruption of the internal thread, the depth of the semi-through groove 2 preferably exceeds the centerline of the nut body 1 by 10mm-15mm. Considering the minimum milling space when machining the groove, the width of the semi-through groove 2 is preferably 4mm-6mm.

[0017] The nut body 1 has a locking threaded hole 3 that extends through to the bottom of the semi-through groove 2 at the location of the semi-through groove 2. Generally, two are arranged symmetrically. A locking screw 4 is installed in the locking threaded hole 3 with a matching diameter. After the locking screw 4 is screwed into the locking threaded hole 3, it can press the end face of the nut body 1.

[0018] During installation, use a torque wrench to tighten the nut body 1 to the specified value first, and then screw the locking screw 4 into the locking thread hole 3 to form a clamping force, pressing the end face of the nut body 1, thereby achieving the effect of locking the horizontal stud 5.

[0019] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
