Description

Technical Field

[0001] This utility model relates to the field of nut technology, and in particular to a rotatable and adjustable locking nut. Background Technology

[0002] Lock nuts are core fasteners used in mechanical connections to secure components and prevent loosening. They are widely used in various scenarios such as general machinery, automobile manufacturing, electronic equipment, and construction machinery. Their ease of use and connection stability directly affect equipment assembly efficiency and long-term operational reliability.

[0003] In actual production assembly and daily maintenance, traditional lock nuts have revealed many adaptability deficiencies. Most conventional lock nuts lack a dedicated grip structure, requiring external tools such as wrenches and sockets for tightening or loosening. In situations where tools are unavailable, such as fieldwork, assembly in confined spaces, or emergency repairs due to sudden malfunctions, quick operation is impossible, delaying the work progress. Some lock nuts with integrated handles can be operated manually, but the handle is fixedly connected to the nut body, increasing the overall size of the nut and making it inconvenient to install and store in compact structures. Furthermore, if the handle wears out or breaks after long-term use, the entire nut needs to be replaced, increasing operating costs.

[0004] Some nuts with a gripping function have smooth surfaces on the gripping parts. When operators tighten them with wet or oily hands, slippage can easily occur, affecting operational efficiency and posing a safety hazard. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotatable and adjustable locking nut.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: it includes a nut body, with connecting components symmetrically connected to the lower side of the nut body, and handles detachably connected to both connecting components, and a rubber ring bonded to the upper side of the nut body.

[0007] As a further description of the above technical solution:

[0008] Both sides of the nut body are provided with slots, and the two handles are each welded with a locking block at the end that is close to each other. The two locking blocks are respectively locked in the two slots.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes two fixing blocks welded to the side of the nut body and located above and below corresponding slots, respectively. Insert rods are slidably connected through both fixing blocks. Insert holes are provided on the upper and lower sides of the handle. The ends of the two insert rods near the handle are respectively inserted into the two insert holes. Pull blocks are welded to the ends of the two insert rods away from the handle. Return springs are sleeved on the outside of the two insert rods.

[0011] As a further description of the above technical solution:

[0012] The two ends of the return spring are welded to the side of the pull block and the side of the fixing block, respectively.

[0013] As a further description of the above technical solution:

[0014] The fixing block has a through hole, and the insertion rod is slidably connected in the through hole.

[0015] As a further description of the above technical solution:

[0016] The nut body has a threaded through hole.

[0017] As a further description of the above technical solution:

[0018] Both grips have anti-slip textures on their surfaces.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, manual rotation adjustment is achieved through symmetrically arranged handles. In scenarios where no tools are carried, such as field operations, assembly in confined spaces, or emergency repairs due to sudden malfunctions, operators can directly hold the handles to tighten and loosen nuts, eliminating reliance on external tools such as wrenches and sockets and improving assembly and maintenance efficiency.

[0021] 2. In this utility model, the handle and the nut body are detachably connected by the connecting component. The handle can be removed and replaced separately without replacing the entire nut body, which reduces the waste of parts and lowers the cost of use and maintenance. At the same time, after the handle is removed, the nut body is smaller in size, which makes it easier to install and store in a compact structure.

[0022] 3. In this utility model, the anti-slip texture on the handle surface increases the friction between the hand and the handle, preventing slippage when the operator's hands are wet or oily; the rubber ring bonded to the upper side of the nut body can enhance the frictional resistance between the tool and the nut body, preventing the tool from slipping when using external tools.

[0029] 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.

[0030] Reference Figures 1-4 One embodiment of this utility model includes a nut body 1, with connecting components 12 symmetrically connected to the lower side of the nut body 1. Each of the two connecting components 12 is detachably connected to a handle 3, and a rubber ring 2 is bonded to the upper side of the nut body 1.

[0031] Both sides of the nut body 1 are provided with slots 11. The two handles 3 are each welded with a locking block 8 at their close ends. The two locking blocks 8 are respectively locked in the two slots 11. The connecting component 12 includes two fixing blocks 6 welded to the side of the nut body 1 and located above and below the corresponding slots 11. The two fixing blocks 6 are slidably connected with insert rods 10. The upper and lower sides of the handles 3 are provided with insertion holes 7. The ends of the two insert rods 10 close to the handles 3 are respectively inserted into the two insertion holes 7. The ends of the two insert rods 10 away from the handles 3 are each welded with a pull block 5. The outside of the two insert rods 10 is fitted with a return spring 9. The two ends of the return spring 9 are respectively welded to the side of the pull block 5 and the side of the fixing block 6. The fixing block 6 is provided with a through hole 13. The insert rod 10 is slidably connected in the through hole 13. The nut body 1 is provided with a threaded through hole 4. The surfaces of the two handles 3 are provided with anti-slip texture.

[0032] Working principle: When installing the grip 3, first pull the pull block 5 in the connecting components 12 on both sides outward. The pull block 5 drives the insertion rod 10 to slide outward along the through hole 13 of the fixing block 6. At this time, the return spring 9 sleeved on the outside of the insertion rod 10 is stretched and stores elastic potential energy. Then, align the locking blocks 8 at one end of the two grips 3 with the corresponding locking slots 11 on both sides of the nut body 1 and lock them in, realizing the initial positioning of the grip 3 and the nut body 1. After releasing the pull block 5, the return spring 9 contracts under the action of elastic restoring force, pulling the insertion rod 10 to move towards the grip 3, so that the end of the insertion rod 10 close to the grip 3 is inserted into the preset insertion holes 7 on the upper and lower sides of the grip 3, completing the firm fixation of the grip 3 and preventing it from loosening or falling off during use.

[0033] When tools are unavailable or inconvenient to use, operators can directly grip the two symmetrically arranged handles 3. The anti-slip texture on the surface of the handles 3 increases the friction between the hand and the handles 3, effectively preventing slippage when hands are wet or oily, thus improving operational stability and safety. By applying force with both hands to rotate the handles 3, the handles 3 drive the nut body 1 to rotate synchronously through the engaging action of the locking block 8 and the locking groove 11. The nut body 1 engages with the bolt through the internal threaded through hole 4, enabling forward tightening or reverse disassembly of the nut on the bolt, meeting the assembly and maintenance needs under different working conditions.

[0034] When the handle 3 is worn, broken, or damaged, or when it is necessary to install the nut in a tight space, the pull block 5 can be pulled again to disengage the insertion rod 10 from the insertion hole 7 of the handle 3, thus releasing the limiting fixation on the handle 3. At this time, the handle 3 can be removed from the slot 11 of the nut body 1, completing the disassembly of the handle 3. A new handle 3 can be replaced separately without replacing the entire nut body 1, reducing usage costs. The nut body 1 after removing the handle 3 is smaller in size, making it easier to install and use in confined spaces.

[0035] The rubber ring 2 has good anti-slip properties. When it is necessary to use tools such as wrenches and sockets to operate the nut body 1 under special working conditions, it can enhance the friction between the tool and the nut body 1, prevent the tool from slipping during the application of force, and further improve the convenience and safety of operation.
