Description

Technical Field

[0001] This utility model relates to the field of adapter technology, specifically a large-size adapter. Background Technology

[0002] In the field of industrial assembly and maintenance, pneumatic wrenches are widely used due to their high efficiency and convenience. To accommodate different tool heads, large-size adapters have become a key component for connecting pneumatic wrenches with various tool heads.

[0003] Traditional large-size adapters have many problems in practical use. The connection structure is poorly designed, and the connection between the tool head and the adapter is not secure enough. It is usually only fixed by a ball pin, which is prone to loosening or even falling off under the vibration generated by the high-speed operation of the pneumatic wrench. This not only affects work efficiency but also poses safety hazards. The disassembly process is cumbersome and often requires additional tools, making it inconvenient to operate and consuming a lot of time and labor costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a large-size adapter.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A large-size adapter includes:

[0007] A socket with a slot at its top for connecting a pneumatic wrench;

[0008] The pneumatic connector is located in the slot of the sleeve, and its side wall has a side hole;

[0009] The elastic push assembly consists of an elastic pusher located in the side hole and a snap-fit ​​member connected to its end. Under normal conditions, the snap-fit ​​member is pushed into the sleeve to form a locked position.

[0010] The guiding structure consists of guide grooves on both sides of the sleeve slot and an auxiliary component that extends laterally through the side wall of the sleeve. The end of the auxiliary component is flush with the bottom of the guide groove. The depth of the snap-fit ​​component extending into the sleeve is one-third of the length of the auxiliary component. The snap-fit ​​component can be released by axially moving the auxiliary component.

[0011] Preferably, the guide groove is provided with a guide slope that is inclined toward the bottom of the sleeve, and the depth of its end is greater than the protrusion height of the snap-fit ​​member.

[0012] Preferably, the snap-fit ​​component is cylindrical or polygonal, and the end of the snap-fit ​​component has an inclined surface with the same inclination angle as the guide groove.

[0013] Preferably, the elastic pusher is a compression spring, which keeps the snap-fit ​​portion protruding from the surface of the pneumatic connector in its naturally extended state.

[0014] Preferably, it also includes a magnetic positioning mechanism, which consists of a magnetic ring disposed on the outer wall of the sleeve and an iron disc disposed at the end of the auxiliary component.

[0015] Preferably, the auxiliary component adopts a push rod structure, and its outer end is provided with a flange for easy manual operation.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Secure connection: When the pneumatic connector is inserted into the socket slot, the elastic pusher is in a naturally extended state, pushing the locking part to protrude from the surface of the pneumatic connector. The locking part moves along the guide slope of the guide groove and locks into the socket, forming a locked position. This ensures that when the pneumatic wrench is working, the power can be effectively transmitted to the pneumatic connector and it is not easy to fall off, thus achieving a secure connection between the pneumatic connector and the socket.

[0018] 2. Easy to disassemble: The operator manually pushes the flange of the auxiliary part, and the auxiliary part moves axially, pushing the snap-fit ​​part to gradually retract into the side hole. When the pneumatic connector is pulled, the inclined surface on the snap-fit ​​part with the same inclination angle as the guide groove allows it to move smoothly along the guide inclined surface, thereby releasing the locking of the snap-fit ​​part and making it easy to remove the pneumatic connector from the sleeve. The disassembly operation is simple and easy.

[0019] 3. Reasonable structure: The auxiliary component adopts a push rod structure, which runs horizontally through the side wall of the sleeve. The end is flush with the bottom of the guide groove. The outer end is provided with a flange for easy manual operation. The depth of the locking component into the sleeve is one-third of the length of the auxiliary component. This structural design allows the auxiliary component to effectively push the locking component, realize the locking and unlocking of the locking component, and ensure the rationality of the adapter structure and the effectiveness of operation.

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] Example

[0028] like Figure 1-4 As shown, a large-size adapter includes:

[0029] The top of the socket 1 is provided with a slot for connecting to a pneumatic wrench. Guide grooves 11 are provided on both sides of the slot of the socket 1. The guide grooves 11 have guide slopes that slope towards the bottom of the socket 1. The depth of the end of the guide groove is greater than the protruding height of the snap-fit ​​23, providing guidance and accommodation space for the movement of the snap-fit ​​23. A magnetic ring 13 is installed on the outer wall of the socket 1 for use with a magnetic positioning mechanism.

[0030] The pneumatic connector 2 is installed in the slot of the sleeve 1, and a side hole 21 is provided on the side wall for installing the elastic push assembly.

[0031] The elastic push assembly consists of an elastic pusher 22 and a locking member 23. The elastic pusher 22 is a compression spring, installed in the side hole 21, and in its naturally extended state, it keeps the locking member 23 partially protruding from the surface of the pneumatic connector 2. Under normal conditions, the elastic pusher 22 pushes the locking member 23 into the sleeve 1 to form a locked position, ensuring a secure connection between the pneumatic connector 2 and the sleeve 1. The locking member 23 is cylindrical or polygonal, with an inclined surface at the end that has the same angle as the guide groove 11, facilitating movement within the guide groove 11.

[0032] The guiding structure consists of a guide groove 11 and an auxiliary component 12. The auxiliary component 12 adopts a push rod structure, which extends laterally through the side wall of the sleeve, with its end flush with the bottom of the guide groove 11. The outer end is provided with a flange for easy manual operation. The locking component 23 extends into the sleeve 1 to a depth of one-third of the length of the auxiliary component 12. By axially moving the auxiliary component 12, the locking component 23 can be pushed into the side hole 21. Pulling the pneumatic connector 2, the locking component 23 on the pneumatic connector 2 can move along the guide groove 11, thereby releasing the locking component 23 and removing the pneumatic connector 2.

[0033] The magnetic positioning mechanism consists of a magnetic ring 13 and an iron plate 14. The magnetic ring 13 is located on the outer wall of the sleeve 1, and the iron plate 14 is located at the end of the auxiliary component 12. When the auxiliary component 12 is in the appropriate position, the magnetic ring 13 and the iron plate 14 attract each other, thereby positioning the auxiliary component 12 and preventing it from moving accidentally.

[0034] In the connection stage, the slot at the top of the socket 1 connects to the pneumatic wrench, providing a power input base for the adapter. When the pneumatic connector 2 is inserted into the slot of the socket 1, the elastic pusher 22 (compression spring) installed in the side hole 21 of the pneumatic connector 2 is in a naturally extended state, pushing the locking member 23 out of the surface of the pneumatic connector 2. The locking member 23 overcomes the elastic force of the elastic pusher 22 and moves along the guide slope of the guide groove 11 on both sides of the socket 1 slot, finally locking into the socket 1. Under the pushing force of the elastic pusher 22, a locking position is formed, thereby achieving a stable connection between the pneumatic connector 2 and the socket 1, ensuring that power can be effectively transmitted to the pneumatic connector 2 when the pneumatic wrench is working, and that it is not easy to fall off.

[0035] When it is necessary to disassemble the pneumatic connector 2, the operator manually pushes the flange of the auxiliary component 12, causing the auxiliary component 12 to move axially. Since the depth of the locking component 23 extending into the sleeve 1 is one-third of the length of the auxiliary component 12, the movement of the auxiliary component 12 can push the locking component 23 to gradually retract into the side hole 21. At this time, pulling the pneumatic connector 2 allows the inclined surface on the locking component 23, which has the same inclination angle as the guide groove 11, to move smoothly along the guide inclined surface of the guide groove 11 until it is completely disengaged from the locking area of ​​the sleeve 1, thereby releasing the locking of the locking component 23 and removing the pneumatic connector 2 from the sleeve 1.

[0036] The magnetic positioning mechanism stabilizes the position of the auxiliary component 12 during the operation of the adapter. A magnetic ring 13 is mounted on the outer wall of the sleeve 1, and an iron disc 14 is positioned at the end of the auxiliary component 12. When the auxiliary component 12 pushes the locking component 23 to complete the unlocking operation and moves to the appropriate position, a mutual attraction is generated between the magnetic ring 13 and the iron disc 14, firmly fixing the auxiliary component 12 in place. This prevents accidental movement due to vibration or other factors during the operation of the adapter, ensuring the structural stability and operational reliability of the adapter under different operating conditions.

[0037] Secure connection: When 2 is inserted into slot 1, 22 is in a naturally extended state, pushing part of 23 to protrude from the surface of 2. 23 moves along the guide slope of 11 and is locked into 1, forming a locking position. This ensures that when the pneumatic wrench is working, the power can be effectively transmitted to 2 and it is not easy to fall off, thus achieving a secure connection between 2 and 1.

[0038] Easy to disassemble: The operator manually pushes the flange of 12, and 12 moves along the axis, pushing 23 to gradually retract into 21. When 2 is pulled, the inclined surface on 23 with the same inclination angle as 11 allows it to move smoothly along the guide inclined surface, thereby releasing the lock of 23 and making it easy to remove 2 from 1. The disassembly operation is simple and easy.

[0039] Stable positioning: 13 is installed on the outer wall of 1, and 14 is set at the end of 12. When 12 pushes 23 to complete the unlocking operation and moves to the appropriate position, 13 and 14 generate mutual attraction, which firmly fixes 12 and prevents it from moving accidentally due to vibration and other factors during the operation of the adapter. This ensures the structural stability and operational reliability of the adapter under different working conditions.

[0040] Good guiding performance: 11 on both sides of slot 1 is provided with guide slopes that slope towards the bottom of 1, which provide guidance and accommodation space for the movement of 23. The end of 23 is provided with a slope with the same tilt angle as 11, which facilitates movement within 11. This allows 23 to move accurately within 11 and realize locking and unlocking operations, improving the working performance of the adapter.

[0041] Reasonable structure: 12 adopts a push rod structure, which runs horizontally through the side wall of 1 and is flush with the bottom of 11 at the end. The outer end is provided with a flange for easy manual operation. 23 extends into 1 to a depth of one-third of the length of 12. This structural design allows 12 to effectively push 23 to lock and unlock 23, ensuring the rationality of the adapter structure and the effectiveness of operation.

[0042] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
