Description

Technical Field

[0001] This invention relates to the field of mechanical assembly technology, specifically to a horizontally opening and closing nut assembly / disassembly sleeve. Background Technology

[0002] Socket wrenches are commonly used tools for tightening and loosening nuts in mechanical assembly, equipment installation and maintenance. They are mainly used to fit over the outside of nuts and work with manual wrenches or power tools to quickly tighten and loosen nuts. They are widely used in industrial equipment, vehicle repair, pipeline installation and other scenarios.

[0003] Currently, commonly used assembly and disassembly tools mainly include traditional sockets, electric sockets, and open-end wrenches, all of which have significant limitations in practical use. Traditional and electric sockets, limited by their depth, cannot fully accommodate bolts and ensure a stable engagement with the nut when the bolt protrudes significantly, leading to problems such as incomplete insertion and slippage, making it difficult to apply force properly. Furthermore, traditional straight-tube sockets have a long axial dimension, making them unsuitable for situations where space is limited, such as when the bolt is close to a wall, equipment, or pipe, and thus cannot be axially inserted and positioned correctly. Even with manual ratchet wrenches, insufficient operating space often results in a very small swing angle, requiring repeated disassembly and re-insertion of the tool, making operation cumbersome and inefficient.

[0004] While open-end wrenches can be inserted into nuts from the side and are suitable for long bolts and confined spaces, they cannot be used with power-driven tools, lack continuous rotation capabilities, and can only be used for small-angle reciprocating movements, resulting in time-consuming and labor-intensive operations. In summary, existing tools cannot simultaneously meet the comprehensive requirements of side insertion, adaptation to long bolts, suitability for confined spaces, power drive, and efficient continuous operation. They suffer from low disassembly and assembly efficiency and inconvenience in complex working conditions, failing to adequately meet the requirements of industrial field maintenance and assembly. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a horizontally opening and closing nut assembly / disassembly sleeve, which solves the problem of existing sleeves being unsuitable for confined space operating environments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lateral opening and closing nut assembly / disassembly sleeve, comprising: a fixed half-ring, a movable half-ring, a hinge, and an opening / closing locking mechanism. The fixed half-ring and the movable half-ring are hinged together by the hinge. This sleeve opens and closes laterally around the hinge via the fixed half-ring and the movable half-ring, allowing the nut to be directly inserted from the side, without being limited by long bolts or front-end space. A fixed drive half-section is fixedly connected to the top of the fixed half-ring, and a movable drive half-section is fixedly connected to the top of the movable half-ring. When the fixed half-ring and the movable half-ring are closed, the fixed drive half-section and the movable drive half-section align to form a complete drive connection channel. It can be used with standard drive tools such as hollow electric torque wrenches, manual ratchet wrenches, electric wrenches, and torque wrenches. The opening / closing locking mechanism is located at the free ends of the fixed half-ring and the movable half-ring. The opening / closing locking mechanism is used to lock and fix the closed fixed half-ring and the movable half-ring, ensuring that they do not spring open when transmitting torque. After unlocking, the sleeve can be opened laterally to remove it.

[0007] Preferably, the opening and closing locking mechanism is a snap-locking mechanism, including a snap-lock mounting base and a snap-locking seat. A snap-locking pin is slidably connected to the inner wall of the snap-lock mounting base. A limit rod is fixedly connected to the top of the snap-locking pin. A pin return spring is fixedly connected to the inner wall of the snap-lock mounting base. The bottom end of the pin return spring is fixedly connected to the top of the snap-locking pin. When the sleeve is closed, the snap-locking pin moves downward under the thrust of the pin return spring and engages in the anti-disengagement groove of the snap-locking seat, thereby achieving automatic locking.

[0008] Preferably, the outer wall of the buckle mounting base is fixedly connected to the outer wall of the fixed half ring, the outer wall of the buckle locking base is fixedly connected to the outer wall of the movable half ring, the bottom of the buckle pin is engaged with the top of the buckle locking base through an anti-disengagement groove, and the anti-disengagement groove is opened in the top wall of the buckle locking base, the side wall of the limiting rod is slidably connected to the inner wall of the buckle mounting base, and when unlocking, the limiting rod is pulled upward to disengage the buckle pin from the anti-disengagement groove, thereby opening the movable half ring.

[0009] Preferably, the opening and closing locking mechanism is a pin-type locking mechanism, including a pin mounting base and a pin locking base. A pin limiting cap is slidably connected to the inner wall of the pin mounting base. A pin body is fixedly connected to the bottom end of the pin limiting cap. A pin return spring is fixedly connected to the top end of the pin body. After the sleeve is closed, the pin return spring pushes the pin body downward to insert into the pin mounting hole of the pin locking base to complete the locking.

[0010] Preferably, the outer wall of the pin mounting seat is fixedly connected to the outer wall of the fixed half-ring, the outer wall of the pin locking seat is fixedly connected to the outer wall of the movable half-ring, the bottom end of the pin body is inserted into the top of the pin locking seat through the pin mounting hole, and the pin mounting hole is opened in the top wall of the pin locking seat. The top end of the pin return spring is fixedly connected to the inner wall of the pin mounting seat. When unlocking, the pin limit cap is pulled upward to make it move the pin body upward and disengage from the pin mounting hole, thereby opening the movable half-ring.

[0011] Preferably, the opening and closing locking mechanism is an eccentric wheel locking mechanism, including a cam mounting seat and a cam locking seat. A sliding rod is slidably connected to the inner wall of the cam mounting seat. A sliding limit rod is fixedly connected to the top of the sliding rod. A cam return spring is fixedly connected to the bottom of the sliding limit rod. A cam fixing seat is fixedly connected to the top of the cam mounting seat. An eccentric cam is rotatably connected to the inner side of the cam fixing seat. When the eccentric cam is turned counterclockwise by 90 degrees, the eccentric cam presses down on the sliding limit rod, pushing the sliding rod downward into the rod locking hole of the cam locking seat to achieve forced locking.

[0012] Preferably, the outer wall of the cam mounting seat is fixedly connected to the outer wall of the fixed half ring, the outer wall of the cam locking seat is fixedly connected to the outer wall of the movable half ring, the top end of the sliding limit rod passes through the cam fixing seat and contacts the bottom of the eccentric cam, the bottom end of the cam return spring is fixedly connected to the inner wall of the cam mounting seat, and the bottom end of the sliding insert rod is inserted into the top of the cam locking seat through the insert rod locking hole, and the insert rod locking hole is opened in the top wall of the cam locking seat. When unlocking, the eccentric cam is reversed to release the pressure, and the sliding insert rod is lifted up and exited from the insert rod locking hole under the action of the spring force, so that the movable half ring can be opened.

[0013] Preferably, the opening and closing locking mechanism is a threaded locking mechanism, including a threaded mounting seat and a threaded locking seat. A threaded limiting block is fixedly connected to the inner wall of the threaded mounting seat, and a locking screw is threadedly connected to the inner wall of the threaded limiting block. An operating knob is fixedly connected to the top end of the locking screw. Rotating the operating knob causes the locking screw to rotate, causing it to screw downwards and insert into the threaded mounting hole of the threaded locking seat to achieve locking.

[0014] Preferably, the outer wall of the threaded mounting seat is fixedly connected to the outer wall of the fixed half ring, the outer wall of the threaded locking seat is fixedly connected to the outer wall of the movable half ring, the locking screw passes through the threaded mounting seat, and the bottom end of the locking screw is inserted into the top of the threaded locking seat through a threaded mounting hole, and the threaded mounting hole is opened in the top wall of the threaded locking seat. When unlocking, the operating knob is rotated in the opposite direction to make the locking screw exit the threaded mounting hole, thereby opening the movable half ring.

[0015] The beneficial effects of this invention are as follows:

[0016] This socket features a horizontally opening and closing structure, allowing it to be directly engaged from the side of the nut. This effectively overcomes the limitations of traditional sockets, which cannot accommodate long bolts or have difficulty reaching into confined spaces. It can smoothly install and remove nuts even in narrow working conditions where the bolt protrudes long, the bolt is close to a wall, or there is dense equipment, making it suitable for a wide range of scenarios. The socket employs a split design with a fixed half-ring and a movable half-ring hinged together. Combined with a split drive structure that forms a complete channel when closed, it can stably connect to tools such as manual ratchet wrenches and hollow electric torque wrenches. It offers both continuous electric rotation and manual small-angle ratchet oscillation modes, providing greater operational flexibility. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1-7 This invention provides a technical solution: a lateral opening and closing nut assembly sleeve, comprising: a fixed half-ring 1, a movable half-ring 3, a hinge 2, and an opening and closing locking mechanism 6. The fixed half-ring 1 and the movable half-ring 3 are hinged together by the hinge 2. A fixed driving half-section 4 is fixedly connected to the top of the fixed half-ring 1, and a movable driving half-section 5 is fixedly connected to the top of the movable half-ring 3. When the fixed half-ring 1 and the movable half-ring 3 are closed, the fixed driving half-section 4 and the movable driving half-section 5 are connected to form a complete driving connection channel. The opening and closing locking mechanism 6 is disposed at the free ends of the fixed half-ring 1 and the movable half-ring 3. The opening and closing locking mechanism 6 is used to lock and fix the closed fixed half-ring 1 and the movable half-ring 3. This sleeve opens and closes laterally around the hinge 2 via the fixed half-ring 1 and the movable half-ring 3, and can be directly inserted into the nut from the side, without being restricted by long bolts and front-end space. After closing, the fixed drive half 4 and the movable drive half 5 mate to form a complete drive channel. The inner side of the drive connection channel is a standard square hole, and the outer side is a hexagonal boss, which can be used with standard drive tools such as hollow electric torque wrenches, manual ratchet wrenches, electric wrenches, and torque wrenches to transmit torque. When the opening and closing locking mechanism 6 is closed, it ensures that it will not spring open when transmitting torque; after unlocking, the socket can be opened laterally to remove it.

[0031] The opening and closing locking mechanism 6 is a snap-locking mechanism, suitable for scenarios requiring quick clamping and one-handed operation. It can be used with manual ratchet wrenches, light electric wrenches, and pneumatic quick-release wrenches. It includes a snap-lock mounting base 611 and a snap-locking seat 612. A snap-locking pin 613 is slidably connected to the inner wall of the snap-lock mounting base 611. A limit rod 614 is fixedly connected to the top of the snap-locking pin 613. A pin return spring 615 is fixedly connected to the inner wall of the snap-lock mounting base 611. The bottom end of the pin return spring 615 is fixedly connected to the top of the snap-locking pin 613. The outer wall of the snap-lock mounting base 611 is fixedly connected to the outer wall of the fixed half-ring 1. The outer wall of the snap-locking seat 612 is fixedly connected to... The outer wall of the movable semi-ring 3 is fixedly connected. The bottom of the locking pin 613 is engaged with the top of the buckle locking seat 612 through the anti-disengagement groove 616, which is located in the top wall of the buckle locking seat 612. The side wall of the limiting rod 614 is slidably connected to the inner wall of the buckle mounting seat 611. When the sleeve is closed, the locking pin 613 moves downward under the thrust of the pin return spring 615 and engages in the anti-disengagement groove 616 of the buckle locking seat 612, achieving automatic locking. The limiting rod 614 slides synchronously with the locking pin 613, limiting its stroke and preventing it from disengaging. The buckle mounting seat 611 provides installation and guiding support for the entire buckle assembly. When unlocking, pulling the limiting rod 614 upward causes the locking pin 613 to disengage from the anti-disengagement groove 616, thus opening the movable semi-ring 3.

[0032] Example 2: Please refer to Figure 1-7 Based on Embodiment 1, this invention provides a technical solution: the opening and closing locking mechanism 6 is a pin-type locking mechanism, which is suitable for conventional disassembly and assembly scenarios with long bolts and limited front-end space. It can be used with manual ratchet wrenches, standard electric wrenches, and conventional torque wrenches. It includes a pin mounting base 621 and a pin locking base 622. A pin limiting cap 623 is slidably connected to the inner wall of the pin mounting base 621. A pin body 624 is fixedly connected to the bottom end of the pin limiting cap 623. A pin return spring 625 is fixedly connected to the top end of the pin body 624. The outer wall of the 21 is fixedly connected to the outer wall of the fixed half-ring 1, and the outer wall of the pin locking seat 622 is fixedly connected to the outer wall of the movable half-ring 3. The bottom end of the pin body 624 is inserted into the top of the pin locking seat 622 through the pin mounting hole 626, and the pin mounting hole 626 is opened in the top wall of the pin locking seat 622. The top end of the pin return spring 625 is fixedly connected to the inner wall of the pin mounting seat 621. After the sleeve is closed, the pin return spring 625 pushes the pin body 624 downward and inserts it into the pin mounting hole 626 of the pin locking seat 622 to complete the locking. The pin mounting seat 621 provides a sliding guide and mounting base for the pin assembly. When unlocking, pull the pin limit cap 623 upward to make it move the pin body 624 upward and disengage it from the pin mounting hole 626, thereby opening the movable half-ring 3.

[0033] Example 3: Please refer to Figure 1-7 Based on Embodiment 1, the present invention provides a technical solution: the opening and closing locking mechanism 6 is an eccentric wheel locking mechanism, which is suitable for high torque, strong torque, and heavy-duty fastening conditions. It can be used with high-torque manual wrenches, heavy-duty electric wrenches, and industrial-grade torque tools. It includes a cam mounting seat 631 and a cam locking seat 632. A sliding rod 634 is slidably connected to the inner wall of the cam mounting seat 631. A sliding limit rod 633 is fixedly connected to the top of the sliding rod 634. A cam return spring 635 is fixedly connected to the bottom of the sliding limit rod 633. A cam fixing seat 636 is fixedly connected to the top of the cam mounting seat 631. An eccentric cam 637 is rotatably connected to the inner side of the cam fixing seat 636. The outer wall of the cam mounting seat 631 is connected to... The outer wall of the fixed half-ring 1 is fixedly connected, the outer wall of the cam locking seat 632 is fixedly connected to the outer wall of the movable half-ring 3, the top end of the sliding limit rod 633 passes through the cam fixing seat 636 and contacts the bottom of the eccentric cam 637, the bottom end of the cam return spring 635 is fixedly connected to the inner wall of the cam mounting seat 631, and the bottom end of the sliding rod 634 is inserted into the top of the cam locking seat 632 through the rod locking hole 638, which is located in the top wall of the cam locking seat 632. After the sleeve is closed, the eccentric cam 637 is turned counterclockwise by 90 degrees, the eccentric cam 637 presses down the sliding limit rod 633, and pushes the sliding rod 634 downward into the rod locking hole 638 of the cam locking seat 632, thus achieving forced locking. The cam return spring 635 provides an upward return force for the sliding limit rod 633, assisting in reset during unlocking. The cam mounting base 631 and the cam fixing base 636 together constitute the mounting and rotation support for the cam mechanism. When unlocking, the eccentric cam 637 is reversed to release the pressure, and the sliding rod 634 is lifted up and disengaged from the rod locking hole 638 under the action of the spring force, thus opening the movable half ring 3.

[0034] Example 4: Please refer to Figure 1-7Based on Embodiment 1, this invention provides a technical solution: the opening and closing locking mechanism 6 is a threaded locking mechanism, which is suitable for heavy-duty scenarios requiring high torque and reliable locking. It can be used with ultra-high torque manual wrenches, heavy-duty electric wrenches, and constant torque fastening tools. It includes a threaded mounting base 641 and a threaded locking base 642. A threaded limiting block 644 is fixedly connected to the inner wall of the threaded mounting base 641. A locking screw 643 is threadedly connected to the inner wall of the threaded limiting block 644. An operating knob 646 is fixedly connected to the top of the locking screw 643. The outer wall of seat 641 is fixedly connected to the outer wall of fixed half-ring 1, and the outer wall of threaded locking seat 642 is fixedly connected to the outer wall of movable half-ring 3. Locking screw 643 passes through threaded mounting seat 641, and the bottom end of locking screw 643 is inserted into the top of threaded locking seat 642 through threaded mounting hole 645, which is located in the top wall of threaded locking seat 642. After the sleeve is closed, rotating the operating knob 646 rotates the locking screw 643, causing it to screw downwards and insert into the threaded mounting hole 645 of threaded locking seat 642 to achieve locking. Threaded limit block 644 restricts the axial position of locking screw 643 to prevent it from coming out. Threaded mounting seat 641 provides threaded engagement and support for the screw. To unlock, rotating the operating knob 646 in the opposite direction causes locking screw 643 to exit the threaded mounting hole 645, thus opening movable half-ring 3.
