[0001] This utility model belongs to the technical field of automotive pipe fitting connecting nuts, specifically a nut for quick installation of automotive pipe fittings. Background Technology

[0002] Automotive pipe fitting connecting nuts are special nuts used for connecting, fastening, and sealing automotive pipe fittings. They are widely used in automotive systems such as oil supply, water supply, and gas supply, and play an important role in the normal operation and driving safety of various automotive systems.

[0003] Existing traditional automotive pipe fitting connecting nuts mostly require multiple rotations with a wrench to reach the preset torque, making the installation and removal of the nuts cumbersome and inefficient. To address this, we propose a quick-installing nut for automotive pipe fitting connections. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a nut for automotive pipe fitting connection that can be installed quickly. It effectively solves the problem that most existing traditional automotive pipe fitting connection nuts require multiple rotations with a wrench to reach the preset torque, making the nut disassembly and assembly operations cumbersome and inefficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-installable automotive pipe fitting connector nut, comprising an automotive pipe fitting connector nut body, wherein a set of limiting mechanisms are symmetrically arranged on the surface of the automotive pipe fitting connector nut body, the automotive pipe fitting connector nut body includes a first nut base, a second nut base is attached to one side of the first nut base, a set of slots are symmetrically opened on the side surface of the first nut base, a set of retaining plates are symmetrically fixed on the side surface of the second nut base, a set of guide grooves are symmetrically opened on the arc-shaped surfaces of the first nut base and the second nut base, a magnetic suction plate is fixed inside the guide grooves, a threaded arc frame is provided on the inner side of the first nut base and the second nut base, and a set of guide blocks are symmetrically fixed on the outer surface of the threaded arc frame.

[0006] Preferably, the second nut base forms an engaging structure with the first nut base through a retaining plate and a retaining groove, wherein the retaining plate and the retaining groove are matched in shape and structure.

[0007] Preferably, the threads of the two threaded arc frames are connected, and the two threaded arc frames form a magnetic attraction structure with the first nut base and the second nut base respectively through a guide block, a guide groove, and a magnetic suction plate.

[0008] Preferably, the first nut base, the second nut base, the clamping plate, and the threaded arc frame are made of aluminum alloy, and the guide block is made of iron.

[0009] Preferably, the limiting mechanism includes an inner groove, a set of inner grooves are symmetrically opened inside the first nut base, a limiting rod passes through the inner groove, a set of limiting ring plates are symmetrically fixedly sleeved on the surface of the limiting rod, and a spring is provided on one side of the limiting ring plate.

[0010] Preferably, the limiting rod is inverted U-shaped, and the limiting rod forms an elastic structure with the limiting ring plate, the spring and the first nut base.

[0011] Preferably, the limiting ring plate and the spring are both located inside the inner groove, and the surface of the clamping plate is provided with a limiting groove that matches the end of the limiting rod. When the spring is at the compression critical value, the end of the limiting rod can be completely disengaged from the clamping groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through precise matching of the card plate and slot and a set of limiting mechanisms, the stability of the overall connection of the nut base is ensured, and the split design allows for quick insertion into pipe fittings, greatly simplifying the traditional installation process that requires screwing the entire nut in, and significantly improving assembly efficiency. The threaded arc frame and the base are connected by guide blocks, guide grooves, and magnetic adsorption plates, ensuring that the two threaded arc frames form a complete thread structure to meet fastening requirements. The magnetic properties also enable quick positioning and temporary fixation during installation, preventing parts from falling off or misaligning. The aluminum alloy base and threaded arc frame combine lightweight and structural strength, while the combination of iron guide blocks and magnetic plates reduces overall cost while ensuring magnetic adsorption. This allows the nut to meet the requirements of high pressure and vibration conditions in automotive pipe fittings while also being durable and economical.

[0013] 2. The elastic structure, consisting of an inverted U-shaped limiting rod, an inner groove, a limiting ring plate, and a spring, allows the end of the limiting rod to be stably engaged in the limiting groove of the clamping plate through the preload of the spring. This securely locks the first nut base and the second nut base together, effectively preventing loosening or separation during vehicle vibrations and ensuring the overall structural stability. When disassembly is required, simply apply external force to the limiting rod to overcome the spring force, allowing the end of the limiting rod to completely disengage from the clamping groove. This convenient and labor-saving operation meets the needs of rapid installation while also facilitating disassembly for later maintenance. The design of the limiting ring plate and spring being built into the inner groove avoids wear or accidental contact caused by exposed components, extending the service life of the limiting mechanism.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3A quick-installable automotive pipe fitting connector nut includes an automotive pipe fitting connector nut body 1. A set of limiting mechanisms 2 are symmetrically arranged on the surface of the automotive pipe fitting connector nut body 1. The automotive pipe fitting connector nut body 1 includes a first nut base 101, a second nut base 102 attached to one side of the first nut base 101, a set of slots 103 symmetrically formed on the side surface of the first nut base 101, and a set of retaining plates 104 symmetrically fixed on the side surface of the second nut base 102. The second nut base 102, through the retaining plates 104 and the slots 103, forms a connection with the first nut base 101. The locking structure features a matching shape between the locking plate 104 and the locking groove 103. A set of guide grooves 105 are symmetrically formed on the arc-shaped surfaces of both the first nut base 101 and the second nut base 102. A magnetic suction plate 106 is fixed inside the guide grooves 105. Threaded arc frames 107 are provided on the inner sides of both the first nut base 101 and the second nut base 102. A set of guide blocks 108 are symmetrically fixed on the outer surface of the threaded arc frames 107. Furthermore, the threads of the two threaded arc frames 107 are connected, and the two threaded arc frames 107 are respectively connected to the guide blocks 108, guide grooves 105, and magnetic suction plates 106. The first nut base 101 and the second nut base 102 form a magnetic locking structure. Furthermore, the first nut base 101, the second nut base 102, the locking plate 104, and the threaded arc frame 107 are made of aluminum alloy, while the guide block 108 is made of iron. Through the precise matching of the locking plate 104 and the locking groove 103, and a set of limiting mechanisms 2, the stability of the overall connection of the nut base is ensured, and the split design allows for quick insertion into pipe fittings, significantly simplifying the traditional installation process where nuts need to be screwed in as a whole, and significantly improving assembly efficiency. The threaded arc frame 107 is connected to the base via the guide block. The combination of guide groove 108 and guide groove 105, along with the adsorption effect of magnetic plate 106, ensures that the two threaded arc frames 107 form a complete threaded structure to meet the fastening requirements. It also utilizes magnetic attraction to achieve rapid positioning and temporary fixation during installation, preventing parts from falling off or misaligning. The aluminum alloy base and threaded arc frame 107 balance lightweight and structural strength, while the combination of iron guide block 108 and magnetic plate 106 reduces the overall cost while ensuring the magnetic attraction effect. This allows the nut to meet the requirements of high pressure and vibration in automotive pipe fittings while also being durable and economical.

[0019] The limiting mechanism 2 includes an inner groove 201. A set of inner grooves 201 are symmetrically opened vertically inside the first nut base 101. A limiting rod 202 passes through the inner grooves 201. A set of limiting ring plates 203 are symmetrically fixedly sleeved on the surface of the limiting rod 202. A spring 204 is provided on one side of the limiting ring plate 203. The limiting rod 202 is inverted U-shaped. The limiting rod 202 forms an elastic structure with the first nut base 101 through the limiting ring plate 203, the spring 204, and the limiting ring plate 203. Furthermore, the limiting ring plate 203 and the spring 204 are both located inside the inner groove 201. The surface of the retaining plate 104 is provided with a limiting groove that matches the end of the limiting rod 202. When the spring 204 is at the compression critical value, the end of the limiting rod 202 can be completely disengaged from the retaining groove 103. The inverted U-shaped limiting rod 202 cooperates with the inner groove 201 and the limiting ring plate. The elastic structure formed by the spring 203 and the spring 204 can stably lock the end of the limiting rod 202 into the limiting groove of the plate 104 through the preload of the spring 204, thereby firmly locking the first nut base 101 and the second nut base 102, effectively preventing them from loosening or separating in the vibration environment of the car, and ensuring the connection stability of the overall structure. When disassembly is required, only an external force needs to be applied to the limiting rod 202 to overcome the elastic force of the spring 204, so that the end of the limiting rod 202 can be completely disengaged from the groove 103. The operation is convenient and labor-saving, which not only meets the needs of rapid installation, but also takes into account the convenience of disassembly during later maintenance. The design of the limiting ring plate 203 and the spring 204 being built into the inner groove 201 avoids wear or accidental contact caused by exposed parts and extends the service life of the limiting mechanism 2.
