Description

Technical Field

[0001] This utility model relates to the field of sleeve technology, and in particular to a sleeve with a stable connection. Background Technology

[0002] A magnetic sleeve is a tool sleeve that incorporates magnetic properties. It is mainly used to attract and secure metal parts (such as screws and nuts) to improve operational efficiency and reduce the risk of parts loss.

[0003] A search revealed a Chinese patent for a magnetically deepened sleeve (authorization announcement number CN210255896U), comprising an internal hexagonal sleeve and a connecting shaft. The connecting shaft is axially mounted at one end of the internal hexagonal sleeve, and a sliding block is axially installed inside the internal hexagonal sleeve. A spring is installed between one end of the sliding block and the inner bottom of the internal hexagonal sleeve, and a magnet is centrally embedded at the other end face of the sliding block. Although this patented technology solves the inconvenience caused by the length of the fastener, the built-in C-shaped iron ring can prevent the magnet from falling off and the thread from slipping.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the current sleeve uses a hexagonal inner hole and spring steel ball locking structure, which is fixed by the steel ball being inserted into the annular groove of the electric screwdriver output shaft. However, the contact area between the steel ball and the groove is limited, and radial displacement is prone to occur under high torque or vibration conditions, which leads to a decrease in connection stability or even accidental dislodgement. In addition, most of the current sleeves are currently integrally molded, and the magnets inside the sleeve will wear and rust after long-term use, making it difficult to replace the magnets inside the existing sleeves. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide a sleeve with a stable connection.

[0006] The technical solution of this utility model is as follows: a sturdy sleeve includes a sleeve body, which is composed of two shells. A hexagonal snap-fit ​​connector is fixedly connected to the top of the sleeve body. An electric screwdriver output shaft is provided at the top of the sleeve body. The electric screwdriver output shaft has a hexagonal snap-fit ​​groove inside that mates with the hexagonal snap-fit ​​connector. A support ring is fixedly connected to the bottom of the electric screwdriver output shaft. Several locking bolts are threaded inside the support ring and are arranged at equal intervals. The outer periphery of the sleeve body has snap-fit ​​holes that mate with the locking bolts. One end of each locking bolt extends into the snap-fit ​​hole. The hexagonal snap-fit ​​groove engages with the hexagonal snap-fit ​​connector.

[0007] By adopting the above technical solution, tightening the locking bolt allows one end of the locking bolt to be inserted into the corresponding locking hole, thereby achieving the purpose of fixing the support ring and the hexagonal locking connector, and reducing the radial displacement of the hexagonal locking connector under high torque conditions.

[0008] In a preferred embodiment, the outer periphery of the sleeve body is provided with a detachable component, the detachable component including a fixing member fixedly connected to the outside of the housing, one of the fixing members having a screw rotatably mounted inside, the screw having a butterfly knob threadedly connected to the outside, the butterfly knob abutting against the other fixing member.

[0009] By adopting the above technical solution, the two fixing parts can be locked by turning the butterfly knob, thereby improving the stability of the housing.

[0010] In a preferred embodiment, two hinges are provided between the two housings, and the two housings are connected by the hinges.

[0011] By adopting the above technical solution, it is convenient for staff to disassemble the shell and remove the hexagonal block and magnet for replacement.

[0012] In a preferred embodiment, the interior of the sleeve body is configured with a hexagonal structure, and a hexagonal block is slidably connected inside the sleeve body. A spring is provided between the hexagonal block and the inner wall of the sleeve body.

[0013] By adopting the above technical solution, the hexagonal block can be pushed downward by the reaction force of the spring, thereby making the magnet and the nut come into contact.

[0014] In a preferred embodiment, a magnet is fixedly mounted on the bottom of the hexagonal block.

[0015] By adopting the above technical solution, it is convenient to use magnets to attract fasteners.

[0016] In a preferred embodiment, the inner wall of the housing is provided with limiting grooves on both sides, and limiting blocks are slidably connected inside the limiting grooves. The two limiting blocks are respectively fixedly connected to the two sides of the hexagonal block.

[0017] By adopting the above technical solution, the hexagonal block can be limited in its lifting and lowering by using the combination of the limiting block and the limiting groove.

[0018] In a preferred embodiment, an adjustment knob is fixedly connected to the end of the locking bolt away from the hexagonal snap-fit ​​connector.

[0019] By adopting the above technical solution, it is convenient for staff to tighten the locking bolts by adjusting the knob.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, the combined use of the hexagonal snap-fit ​​groove and the hexagonal snap-fit ​​connector not only plays a certain positioning role, ensuring smooth docking between the electric screwdriver output shaft and the hexagonal snap-fit ​​connector, but also improves the torsional resistance of the hexagonal snap-fit ​​connector. As the locking bolt is tightened, one end of the locking bolt can be inserted into the corresponding snap-fit ​​hole, thereby achieving the purpose of fixing the support ring and the hexagonal snap-fit ​​connector, reducing the radial displacement of the hexagonal snap-fit ​​connector under high torque conditions, and thus ensuring the connection stability of the sleeve body.

[0022] 2. In this utility model, the two fixing parts can be locked by turning the butterfly knob, thereby improving the stability of the housing. At the same time, it is convenient for staff to disassemble the housing and remove the hexagonal block and magnet for replacement, thereby reducing subsequent maintenance costs.

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

[0030] Reference Figure 1-5 A securely connected sleeve includes a sleeve body 1, which is composed of two housings 101. A hexagonal snap-fit ​​connector 7 is fixedly connected to the top of the sleeve body 1. An electric screwdriver output shaft 8 is provided at the top of the sleeve body 1. The electric screwdriver output shaft 8 has a hexagonal snap-fit ​​groove 10 inside that mates with the hexagonal snap-fit ​​connector 7. A support ring 9 is fixedly connected to the bottom of the electric screwdriver output shaft 8. Several locking bolts 11 are threaded inside the support ring 9 and are arranged at equal intervals. The outer periphery of the sleeve body 1 has locking holes 6 that mate with the locking bolts 11. One end of each locking bolt 11 extends into the locking hole. Inside hole 6, hexagonal snap-fit ​​groove 10 engages with hexagonal snap-fit ​​connector 7. The cooperation of hexagonal snap-fit ​​groove 10 and hexagonal snap-fit ​​connector 7 not only plays a certain positioning role, ensuring smooth docking between electric screwdriver output shaft 8 and hexagonal snap-fit ​​connector 7, but also improves the torsional resistance of hexagonal snap-fit ​​connector 7. As the locking bolt 11 is tightened, one end of the locking bolt 11 can be inserted into the corresponding snap-fit ​​hole 6, thereby achieving the purpose of fixing support ring 9 and hexagonal snap-fit ​​connector 7, reducing radial displacement of hexagonal snap-fit ​​connector 7 under high torque conditions, and thus ensuring the connection stability of sleeve body 1.

[0031] Specifically, the outer periphery of the sleeve body 1 is provided with a detachable component, which includes a fixing member 3 fixedly connected to the outside of the housing 101. By turning the butterfly knob 5, the two fixing members 3 can be locked, thereby improving the stability of the housing 101 in use. At the same time, it is convenient for the staff to disassemble the housing 101 and remove the hexagonal block 13 and magnet 14 for replacement, thereby reducing subsequent maintenance costs. One of the fixing members 3 has a screw 4 rotatably installed inside, and the outside of the screw 4 is threadedly connected to the butterfly knob 5. The butterfly knob 5 is connected to the other... An outer fixing member 3 is pressed against the two housings 101. Two hinges 2 are provided between the two housings 101 and the two housings 101 are connected by the hinges 2. The interior of the sleeve body 1 is set as a hexagonal structure. A hexagonal block 13 is slidably connected inside the sleeve body 1. By the reaction force of the spring 12, the hexagonal block 13 can be pushed downward, so that the magnet 14 can come into contact with the nut. This can be used for nuts or other fasteners of different depths, thereby improving the applicability of the device. A spring 12 is provided between the hexagonal block 13 and the inner wall of the sleeve body 1.

[0032] Specifically, a magnet 14 is fixedly installed at the bottom of the hexagonal block 13, and limit grooves 16 are opened on both sides of the inner wall of the housing 101. Through the cooperation of the limit block 15 and the limit groove 16, the lifting and lowering of the hexagonal block 13 can be limited to a certain extent, making the hexagonal block 13 more stable during lifting and lowering. The limit block 15 is slidably connected inside the limit groove 16. The two limit blocks 15 are fixedly connected to the two sides of the hexagonal block 13 respectively. An adjustment knob is fixedly connected to the end of the locking bolt 11 away from the hexagonal snap-fit ​​connector 7, so that the operator can turn the locking bolt 11 by adjusting the knob.

[0033] Working principle: First, the hexagonal snap-fit ​​slot 10 and hexagonal snap-fit ​​connector 7 are used to allow the operator to insert the hexagonal snap-fit ​​connector 7 into the hexagonal snap-fit ​​slot 10 inside the electric screwdriver output shaft 8, and tighten it with the locking bolt 11. As the locking bolt 11 is tightened, one end of the locking bolt 11 can be inserted into the corresponding snap-fit ​​hole 6, thereby fixing the support ring 9 and the hexagonal snap-fit ​​connector 7. Then, by turning the butterfly knob 5, the two fixing parts 3 can be locked, thereby improving the stability of the housing 101. At the same time, it is convenient for the operator to disassemble the housing 101 and remove the hexagonal block 13 and magnet 14 for replacement, thereby reducing subsequent maintenance costs. In actual use, the reaction force of the spring 12 can push the hexagonal block 13 downward, thereby causing the magnet 14 to come into contact with the nut. This can be used for nuts or other fasteners of different depths, and the magnet 14 is used to attract the fastener.
