Description
Technical Field
[0001] This utility model relates to the technical field of nuts, specifically a tapered nut for automobiles. Background Technology
[0002] Lock nuts can be installed on mating parts such as shafts or bolts through their internal threads, and can be used to position and fix components located on the end side of the lock nut. For example, lock nuts can be installed on spindles, and the locking torque of the lock nut provides axial load to the spindle bearings to maintain proper clearance of the spindle bearings.
[0003] When using existing automotive tapered nuts, they are usually clamped and rotated with a wrench or other tools to tighten or loosen them. If the clamping force of the wrench is too great, the nut will be deformed, affecting the normal tightening or loosening of the copper nut. In addition, the nut may loosen and fall off during use, affecting its performance.
[0004] Therefore, we propose a tapered nut for automobiles to solve the problems mentioned above. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1: Please refer to Figure 1-4 A conical nut for automobiles includes a nut body 1 and a reinforcing threaded tube 2 fixedly installed at the bottom of the nut body 1. A reinforcing block 3 is fixedly sleeved on the upper outer side of the reinforcing threaded tube 2, and the top of the reinforcing block 3 is fixedly installed at the bottom of the nut body 1. Protective components 4 are respectively installed in the middle of the front and rear sides of the nut body 1. Rectangular grooves are respectively opened on both sides of the nut body 1, and the inner cavity of the rectangular grooves is connected to the inner cavity of the nut body 1. Anti-loosening components 5 are respectively installed in the inner cavity of the rectangular grooves. The setting of the protective components 4 facilitates the rotation of the nut body 1 without damaging the nut body 1, while the setting of the anti-loosening components 5 can play the role of preventing the nut body 1 from being separated from the screw.
[0021] The anti-detachment component 5 includes a movable plate 51 slidably installed on one side of the rectangular groove cavity and a limiting toothed rod fixedly installed at equal intervals on the inner side of the movable plate 51. A threaded rod 52 is fixedly installed in the middle of the outer side of the movable plate 51, and a threaded sleeve 53 is threadedly installed on the output shaft of the threaded rod 52. One end of the threaded sleeve 53 is movably installed on the inner wall of the rectangular groove cavity. A worm gear 54 is fixedly sleeved on the output shaft of the threaded sleeve 53. A worm 55 is meshed on the front side of the worm gear 54. A through-hole is opened at the top of the rectangular groove cavity. A bearing is fixedly installed in the inner cavity of the through-hole. A rectangular opening communicating with the through-hole is opened on one side of the top of the nut body 1. The upper end of the worm 55 extends movably through the shaft to the inner cavity of the rectangular opening, which can drive the limiting toothed rod to move relative to each other, thereby achieving the anti-detachment function.
[0022] A knob 551 is fixedly installed on the upper end of the worm gear 55, which can be rotated to drive the worm gear 55 to rotate.
[0023] In this embodiment: During use, the external screw thread is passed through the nut body 1 and the threaded sleeve 53. After passing through, the operator can use an external tool to insert the nut body 1 and drive the nut body 1 and the threaded sleeve 53 to rotate on the external screw. After rotating and moving to a suitable position, the rotation can be stopped. Then, the knobs 551 on both sides are rotated to drive the adjacent worm gear 55 to rotate. When the worm gear 55 rotates, it will drive the worm wheel 54 to rotate. When the worm wheel 54 rotates, it will drive the threaded sleeve 53 to rotate. When the threaded sleeve 53 rotates, it will drive the moving plate 51 to move relative to the threaded rod 52, thereby driving the limiting gear to move relative to the external screw and engage with it, which plays a role in preventing disengagement and limiting the movement.
[0024] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 1-4 The protective component 4 includes a protective plate 41 attached to the middle of the front side of the nut body 1 and slots on both sides of the rear side of the protective plate 41. Inserts 42 are inserted into the inner cavity of the slots respectively. The front side of the inserts 42 is fixedly installed on the nut body 1. Positioning holes are opened on the outer side of the inserts 42 respectively, and threaded holes are opened on the outer side of the inner cavity of the slot respectively. Circular grooves communicating with the threaded holes are opened on both sides of the protective plate 41. T-shaped screws 43 are provided in the inner cavity of the circular grooves respectively, and the output ends of the T-shaped screws 43 are threaded through and extend into the inner cavity of the positioning holes, which serves to protect the nut body 1 when it rotates and to facilitate disassembly and replacement.
[0025] A positioning block 411 is fixedly installed on the rear side of the protective plate 41, and a positioning groove is provided in the middle of the front side of the nut body 1. The rear side of the positioning block 411 extends into the inner cavity of the positioning groove, which plays the role of positioning the protective plate 41.
[0026] In this embodiment: when the tool clamps the nut body 1, it will contact the protective plate 41, which will prevent the nut body 1 from being damaged and improve the service life of the nut body 1. After long-term use, the protective plate 41 can be disassembled and replaced. By rotating the T-shaped screw 43, it will move in the opposite direction under the action of the threaded hole, thereby moving away from the inner cavity of the positioning hole, so that the protective plate 41 can be disassembled and removed.
[0027] Working principle: In use, the external screw thread is passed through the nut body 1 and the threaded sleeve 53. After passing through, the operator can use an external tool to insert the nut body 1 and drive the nut body 1 and the threaded sleeve 53 to rotate on the external screw. After rotating and moving to the appropriate position, the rotation can be stopped. Then, the knobs 551 on both sides are turned to drive the adjacent worm gear 55 to rotate. When the worm gear 55 rotates, it will drive the worm wheel 54 to rotate. When the worm wheel 54 rotates, it will drive the threaded sleeve 53 to rotate. When the threaded sleeve 53 rotates, it will drive the moving plate 51 to move relative to the threaded rod 52, thereby driving the limiting gear to move relative to the threaded rod and engage with the external screw, which plays a role in preventing disengagement and limiting the movement. When the tool clamps the nut body 1, it will contact the protective plate 41, which will prevent damage to the nut body 1 and improve the service life of the nut body 1. After long-term use, the protective plate 41 can be disassembled and replaced. By rotating the T-shaped screw 43, it will move in the opposite direction under the action of the threaded hole, thereby moving away from the inner cavity of the positioning hole, and the protective plate 41 can be disassembled and removed.
