[0002] Some actuators are equipped with manual operating tools, such as wrenches, which are used manually to operate valves, baffles, and other equipment. Making the wrench handle longer makes it easier to operate, but it also causes the end of the handle to extend beyond the actuator housing, making the actuator occupy more space and causing inconvenience in transportation and use.

[0003] Therefore, how to reduce space occupation while ensuring labor-saving operation is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a wrench, which includes a wrench body and a wrench handle.

[0007] In one alternative embodiment of the wrench, the first handle or the second handle having the insert includes a body and an insert. The body has a recess for inserting the insert. The outer contour of the cross-section of the insert is non-circular. One end of the insert protrudes from the recess to form the rotation-limiting post segment. The guide post segment is formed in the body.

[0008] In one alternative embodiment of the wrench, the wrench includes a first magnetic element, and the first handle and / or the second handle are assembled with the first magnetic element. When the first handle and the second handle are connected, the first handle and the second handle are attracted together by the first magnetic element.

[0009] In one alternative embodiment of the wrench, a first groove for accommodating the first magnetic component is provided on the end face of the rotation limiting column segment away from the orifice, and / or, an end wall is provided on the end of the rotation limiting hole segment away from the orifice, and the end wall is provided with a first groove for accommodating the first magnetic component.

[0010] This application also provides an actuator, which includes a wrench as described in any of the above claims, and an actuator shaft. The wrench body is sleeved outside the actuator shaft, and the wrench can drive the actuator shaft to rotate when it swings.

[0029] This application provides a wrench and actuator. In order to enable those skilled in the art to better understand the technical solution of this application, the technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 As shown, the wrench includes a wrench body 10 and a wrench handle, wherein the wrench handle includes a first handle 20 and a second handle 30. The first handle 20 is fixedly connected to the wrench body 10 or integrally formed therefrom. In the illustrated embodiment, the length of the first handle 20 is less than the length of the second handle 30; alternatively, the length of the first handle 20 may be equal to or greater than the length of the second handle 30.

[0031] like Figure 2 and Figure 3As shown, the first handle 20 is provided with a first connecting part 201, and the second handle 30 is provided with a second connecting part 301. The first connecting part 201 and the second connecting part 301 can be detachably connected, so that the first handle 20 and the second handle 30 can be detachably connected.

[0032] When the wrench needs to be rotated, the second connecting part 301 of the second handle 30 can be connected to the first connecting part 201 of the first wrench, so that the total length of the wrench handle can be extended, thereby making the lever arm larger and easier to operate. After rotation is completed, the second handle 30 can be detached from the first handle 20 for separate storage.

[0033] Specifically, the detachable connection methods of the first connecting part 201 and the second connecting part 301 include, but are not limited to, plug-in, snap-in, threaded connection, etc.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, the first connecting part 201 and the second connecting part 301 can be either a socket or a plug adapted to the socket. The plug and socket can be inserted into each other, allowing for easy connection and disconnection of the first handle 20 and the second handle 30 simply by plugging and unplugging. In the illustrated embodiment, the first connecting part 201 is a socket and the second connecting part 301 is a plug. Alternatively, the first connecting part 201 can be a plug and the second connecting part 301 can be a socket.

[0035] Specifically, such as Figure 2 As shown, one end of the socket is provided with an opening for inserting a post, and the socket includes a rotation-limiting section 201a. For example... Figure 3 As shown, the insert includes a rotation-limiting post segment 301a adapted to the rotation-limiting hole segment 201a. That is, the outer contour shape of the cross-section of the rotation-limiting post segment 301a is similar to the inner contour shape of the cross-section of the rotation-limiting hole segment 201a, and to ensure assemblability, the outer contour dimension of the cross-section of the rotation-limiting post segment 301a should be slightly smaller than the inner contour dimension of the cross-section of the rotation-limiting hole segment 201a. The outer contour shape of the cross-section of the rotation-limiting post segment 301a is non-circular; for example, it can be a regular hexagon, so that the rotation-limiting post segment 301a cannot rotate within the rotation-limiting hole segment 201a.

[0036] Specifically, such as Figure 2 As shown, the insertion hole includes a guide hole section 201b, which is located at the end of the rotation-limiting hole section 201a near the opening. The insertion post includes a guide post section 301b that is adapted to the guide hole section 201b. Figure 3As shown, the insert includes a guide post segment 301b adapted to the guide hole segment 201b. That is, the outer contour shape of the cross-section of the guide post segment 301b is similar to the inner contour shape of the cross-section of the guide hole segment 201b, and to ensure assemblability, the outer contour dimension of the cross-section of the guide post segment 301b should be slightly smaller than the inner contour dimension of the cross-section of the guide hole segment 201b. The outer contour shape of the cross-section of the guide post segment 301b is non-circular, for example, it can be square. When the rotation-limiting post segment 301a is inserted into the rotation-limiting hole segment 201a, the guide hole segment 201b and the guide post segment 301b cooperate to guide the insertion direction, thereby preventing misalignment and jamming. The radial dimension of the outer contour of the cross-section of the guide post segment 301b is larger than the radial dimension of the outer contour of the cross-section of the rotation-limiting post segment 301a.

[0037] Specifically, such as Figure 3 As shown, the first handle 20 or the second handle 30, which has a pin, includes a body 302 and an insert 303. In the illustrated embodiment, the second handle 30 has a pin and includes a body 302 and an insert 303. The body 302 has a recess 302a for inserting the insert 303. The outer contour of the cross-section of the insert 303 is non-circular, for example, it can be a regular hexagon. One end of the insert 303 protrudes from the recess 302a to form the aforementioned rotation-limiting post segment 301a. One end of the body 302 has the aforementioned guide post segment 301b, meaning that the guide post segment 301b is formed in the body 302. In this way, the body 302 and the insert 303 can be manufactured separately, resulting in lower costs. Alternatively, the insert 303 can be omitted, and the rotation-limiting post segment 301a and the guide post segment 301b can be integrally formed.

[0038] Specifically, such as Figure 2 As shown, the wrench includes a first magnetic element 40, and a first handle 20 is assembled with the first magnetic element 40. When the first handle 20 and the second handle 30 are connected, they are attracted to each other by the first magnetic element 40. Alternatively, the first magnetic element 40 can also be assembled to the second handle 30, or one first magnetic element 40 can be assembled to each of the first handle 20 and the second handle 30, and the two first magnetic elements 40 can attract each other.

[0039] Specifically, such as Figure 2As shown, when the first magnetic component 40 is assembled on the handle with the insertion hole, a first groove 202 can be provided on the end wall of the rotation-limiting hole section 201a away from the hole opening, and the first magnetic component 40 can be accommodated in the first groove 202. When the first magnetic component 40 is assembled on the handle with the insertion post, a first groove 202 can be provided on the end face of the insertion post section 301a away from the hole opening, and the first magnetic component 40 can be accommodated in the first groove 202. In this way, one end face of the first magnetic component 40 is not obstructed, thereby better exerting the magnetic adsorption effect.

[0040] like Figure 4 As shown, the actuator provided in this application includes the aforementioned wrench and an actuator shaft. The wrench body 10 is fitted onto the outside of the actuator shaft, and when the wrench swings, it can drive the actuator shaft to rotate to control equipment such as valves and baffles.

[0041] Specifically, the wrench body 10 is connected to the actuator shaft via a screw. The rotation-limiting post section 301a of the second handle 30 can engage with the screw, meaning the screw can be unscrewed using the second handle 30. After the screw is unscrewed, the wrench body 10 and the first handle 20 can be pulled out along the axial direction of the actuator shaft. Specifically, when the screw is an internal hexagonal head screw, the outer contour of the cross-section of the rotation-limiting post section 301a is a regular hexagon.

[0042] Specifically, such as Figure 4 As shown, the actuator also includes a housing 60, with one end of the actuator shaft extending outside the housing 60, and the wrench body 10 fitted around that end of the actuator shaft. The housing 60 is provided with a third connecting part 601, which can be detachably connected to the second connecting part 301 of the second handle 30, so that the housing 60 and the second handle 30 can be detachably connected.

[0043] When the wrench needs to be operated by swinging it, the second handle 30 is connected to the first handle 20. When the wrench is not needed for operation, the second handle 30 can be detached from the first handle 20 and connected to the housing 60 for storage. This avoids the problem of the second handle 30 being constantly connected to the first handle 20, resulting in a long total handle length that extends beyond the side of the housing 60, thus occupying a large space for the actuator and causing inconvenience in use and transportation.

[0044] Specifically, the detachable connection methods between the third connecting part 601 and the second connecting part 301 include, but are not limited to, plug-in, snap-fit, and threaded connection.

[0045] In the illustrated embodiment, the second connecting part 301 is a plug, and the structure of the third connecting part 601 is basically the same as that of the first connecting part 201, which is a socket that can be adapted to the plug. In this way, the connection and separation of the second handle 30 and the outer shell 60 can be achieved by simply plugging and unplugging, which is relatively convenient.

[0046] Specifically, such as Figure 5 As shown, the actuator includes a second magnetic element 50, and the housing 60 is assembled with the second magnetic element 50. When the second handle 30 and the housing 60 are connected, the second handle 30 and the housing 60 are attracted together by the second magnetic element 50. In the illustrated embodiment, an end wall is provided at the end of the insertion hole of the housing 60 away from the hole, and a second groove 604 is provided on this end wall, in which the second magnetic element 50 is accommodated. Alternatively, the second magnetic element 50 can also be assembled on the second handle 30, or one second magnetic element 50 can be assembled on both the second handle 30 and the housing 60, and the two second magnetic elements 50 attract each other. Alternatively, a magnetic element can be assembled on the second handle 30, which serves both as a first magnetic element 40 attracting the housing 60 and as a second magnetic element 50 attracting the first handle 20.

[0047] like Figure 4 As shown, the outer casing 60 has a recessed portion 602, which surrounds the outer side of the actuator shaft. The wrench body 10 is at least partially located within the recessed portion 602. The inner surface of the recessed portion 602 is contoured to the outer surface of the wrench body 10. This improves the overall integrity of the actuator. Specifically, one side of the recessed portion 602 has a side opening 602a, through which the first handle 20 protrudes. This allows for direct operation of the first handle 20 when a small amplitude swing of the wrench is required.

[0048] like Figure 4 As shown, the housing 60 has a notch 603, which is located on the side of the recess 602 with the side opening 602a and on the side of the third connecting part 601. When the second connecting part 301 of the second handle 30 is connected to the third connecting part 601 of the housing 60, the second handle 30 is accommodated in the notch 603. In this way, using the notch 603 to accommodate the second handle 30 is more conducive to reducing the footprint of the actuator.

[0049] like Figure 4 As shown, when the second handle is connected to the housing 60, the second handle 30 is located below the first handle 20 and has a gap with the first handle 20. This results in higher integration, a smaller footprint, and the swing of the first handle 20 is not affected when the second handle 30 is connected to the housing 60.

[0050] In summary, the core idea of ​​this application is to fix or integrally set a first handle 20 on the wrench body 10, and to detachably connect a second handle 30 to the first handle 20. When using the wrench, the second handle 30 can be connected to the first handle 20 to make operation easier. When the wrench is not in use, the second handle 30 can be detached and stored separately, avoiding the problem that the second handle 30 is always connected to the first handle 20, resulting in a long total handle length and large space occupation.

[0051] The above examples illustrate the principles and implementation methods of this application. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
