Description
Technical Field
[0001] This application relates to the field of wire installation, and more particularly to a wire fixing device and an underwater cleaning robot. Background Technology
[0002] For devices with wired connections, wire fixing devices are installed. For example, in an underwater cleaning robot with a power-connected wire, one end of the power-connected wire is connected to the robot's battery compartment. To prevent stress on the power-connected wire caused by pulling or its own weight from being transmitted along the power-connected wire to the connection point with the battery compartment, thus avoiding unreliable connection between the power-connected wire and the battery compartment, a wire fixing device is usually added to the power-connected wire.
[0003] Current cable fixing devices generally include a cable retainer and screws. Taking the underwater cleaning robot mentioned above as an example, the power cable is connected to the cable retainer, and the cable retainer is detachably connected to the battery compartment by screws, so that the cable fixing device can improve the reliability of the connection between the power cable and the battery compartment.
[0004] However, when maintaining or repairing equipment with wires connected, such as underwater cleaning robots, the screws need to be removed before the power wires can be disassembled or fixed relative to the wire fixing device. This is cumbersome and results in low efficiency in disassembling and assembling the wires relative to the wire fixing device. Utility Model Content
[0005] In view of this, embodiments of this application provide a line fixing device and an underwater cleaning robot to at least partially solve the above-mentioned problems.
[0006] According to a first aspect of the present application, a wire fixing device is provided, comprising: a fixing post and a wire clamping member; the fixing post includes a connecting end connected to a mounting surface of the fixing post and a sleeve end away from the connecting end; the wire clamping member includes a connecting portion and a clamping portion connected to each other, the connecting portion being rotatably connected to the fixing post so as to drive the clamping portion to move between a first position and a second position; when the clamping portion is in the first position, the clamping portion restricts the fixing ring sleeved on the fixing post from disengaging from the fixing post by locking it onto the sleeve end; when the clamping portion is in the second position, the clamping portion allows the fixing ring to disengage.
[0007] In one possible implementation, the connecting part is rotatably connected to the sleeve end; when the pressing part is in the first position, the distance between the two points with the largest distance in the orthographic projection of the pressing part on the target plane is greater than the distance between the two points with the largest distance in the orthographic projection of the pressing part on the target plane when the pressing part is in the second position, and the target plane is any dummy plane perpendicular to the length direction of the fixed column.
[0008] In one possible implementation, the pressure line is connected to a handle.
[0009] In one possible implementation, the connecting portion is connected to a damping member, which restricts the rotation of the connecting portion relative to the fixed post when the pressure part is in the first position by abutting against the fixed post or a structure fixedly connected to the fixed post; or, the fixed post is connected to a damping member, which restricts the rotation of the connecting portion relative to the fixed post when the pressure part is in the first position by abutting against the connecting portion or a structure fixedly connected to the connecting portion.
[0010] In one possible implementation, the damping element includes a protrusion. If the damping element is connected to the connecting portion, a groove is formed on the connecting portion connected to the protrusion and on the fixing post or the structure fixedly connected to the fixing post. If the damping element is connected to the fixing post, a groove is formed on the fixing post connected to the protrusion and on the connecting portion or the structure fixedly connected to the connecting portion. When the pressure part is in the first position, the protrusion is engaged in the groove, and when the pressure part is in the second position, the protrusion is disengaged from the groove.
[0011] In one possible implementation, the protrusion is connected to the connecting part, a retaining post is provided inside the fixing post, and the groove is formed at the end of the retaining post away from the sleeve end.
[0012] In one possible implementation, the area enclosed by the outer contour of the cross-section of the fixed post perpendicular to the target direction gradually increases, where the target direction is the direction from the end of the sleeve to the connecting end.
[0013] In one possible implementation, the connecting end is connected to a connecting seat for detachable connection with the mounting surface of the fixed post.
[0014] According to a second aspect of the embodiments of this application, an underwater cleaning robot is provided, including a wire fixing device and a battery sealing chamber as described in the first aspect and any implementation thereof; a battery is disposed inside the battery sealing chamber, a terminal block is disposed on one side of the battery sealing chamber, one end of the battery wire is connected to the battery through the terminal block, the mounting surface of the fixing post is the side of the battery sealing chamber where the terminal block is disposed, and the fixing ring is connected to the battery wire.
[0015] In one possible implementation, the distance between the fixing post and the terminal block is less than a preset distance.
[0016] In this embodiment, during the process of fixing the wiring with the wire fixing device, the connecting part is first rotated relative to the wire pressing part until the wire pressing part is in the second position. After the fixing ring is fitted onto the fixing post, the connecting part is then rotated relative to the wire pressing part until the wire pressing part is in the first position. During the process of disassembling the wiring with respect to the wire fixing device, the connecting part is simply rotated relative to the wire pressing part until the wire pressing part is in the second position. Therefore, compared to disassembling the wiring with respect to the wire fixing device by removing screws or other methods, this embodiment allows for direct disassembly and assembly of the wiring with respect to the wire fixing device simply by rotating the connecting part relative to the wire pressing part. This is simple and convenient, improving the efficiency of disassembling and assembling the wiring with respect to the wire fixing device. Attached Figure Description

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0026] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0027] The wire fixing device and underwater cleaning robot provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0028] like Figure 1 and Figure 2 As shown, the wire fixing device provided in this application embodiment can be used to fix the wire 1 by the fixing ring 2 connected to the wire 1. This application embodiment does not limit the specific structure of the fixing ring 2 or the connection method between the wire 1 and the fixing ring 2. In a specific example, the fixing ring 2 is a cylindrical tube, and the fixing ring 2 is integrally connected to the coil 21, which is sleeved on the outside of the wire 1.
[0029] like Figure 2 and Figure 3 As shown, the wire fixing device includes a fixing post 3 and a wire pressing member 4; the fixing post 3 includes a connecting end 31 connected to the mounting surface 71 of the fixing post 3 and a sleeve end 32 away from the connecting end 31; the wire pressing member 4 includes a connecting part 41 and a wire pressing part 42 connected to each other, the connection between the connecting part 41 and the wire pressing part 42 can be a fixed connection (the fixed connection in this application can specifically be an integral connection or a detachable fixed connection, etc., which is not limited in this embodiment), the connecting part 41 is rotatably connected to the fixing post 3 so as to drive the wire pressing part 42 to move between a first position and a second position; when the wire pressing part 42 is in the first position, the wire pressing part 42 restricts the fixing ring 2 sleeved on the fixing post 3 from disengaging from the fixing post 3 by locking it in the sleeve end 32; when the wire pressing part 42 is in the second position, the wire pressing part 42 allows the fixing ring 2 to disengage.
[0030] During the process of fixing the wire 1 using the wire fixing device, the connecting part 41 can be rotated relative to the wire pressing part 4 until the wire pressing part 42 is in the second position. Then, the fixing ring 2 connected to the wire 1 is sleeved on the outside of the fixing post 3. Next, the connecting part 41 is rotated relative to the wire pressing part 4 until the wire pressing part 42 is in the first position. At this time, the wire pressing part 42 restricts the fixing ring 2 sleeved on the fixing post 3 from detaching from the fixing post 3 by locking it on the sleeve end 32, so that the fixing ring 2 connected to the wire 1 is more firmly connected to the fixing post 3. This achieves a more stable fixation of the wire 1 on the mounting surface 71 of the fixing post 3, that is, the wire fixing device can fix the wire 1. At this time, the wire fixing device can strengthen the connection between the wire 1 and the mounting surface 71, so as to reduce the stress transmitted along the wire 1 after the wire 1 is pulled or due to its own weight, etc., and improve the connection reliability of the wire 1.
[0031] During the process of disassembling the wire 1 relative to the wire fixing device, the connecting part 41 can be rotated relative to the wire pressing part 4 until the wire pressing part 42 is in the second position. Then, the fixing ring 2 is removed from the fixing post 3, thus separating the fixing ring 2 from the fixing post 3, thereby achieving the disassembly of the wire 1 relative to the wire fixing device.
[0032] In this embodiment, during the process of fixing the wire 1 using the wire fixing device, the connecting part 41 is first rotated relative to the wire pressing part 42 until the wire pressing part 42 is in the second position. After the fixing ring 2 is fitted onto the fixing post 3, the connecting part 41 is then rotated relative to the wire pressing part 4 until the wire pressing part 42 is in the first position. During the process of disassembling the wire 1 relative to the wire fixing device, the connecting part 41 is simply rotated relative to the wire pressing part 4 until the wire pressing part 42 is in the second position. Therefore, compared to disassembling the wire 1 relative to the wire fixing device by removing screws or similar methods, this embodiment allows for direct disassembly and assembly of the wire 1 relative to the wire fixing device simply by rotating the connecting part 41 relative to the wire pressing part 42. This method is simple and convenient, improving the efficiency of disassembling and assembling the wire 1 relative to the wire fixing device.
[0033] In one possible implementation, such as Figure 3 and Figure 4 As shown, the connecting part 41 is rotatably connected to the sleeve end 32; when the pressing part 42 is in the first position, the distance between the two points with the largest distance in the orthographic projection of the pressing part 42 on the target plane is greater than the distance between the two points with the largest distance in the orthographic projection of the pressing part 42 on the target plane when the pressing part 42 is in the second position, wherein the target plane is any dummy plane perpendicular to the length direction of the fixed column 3.
[0034] The difference in the distance between the two points with the largest distance in the orthographic projection of the pressure part 42 on the target plane when it is in the first position and the second position is due to the shape of the pressure part 42 and the difference in the angle of the pressure part 42 relative to the target plane when it is in the first position and the second position.
[0035] Since the connecting part 41 is rotatably connected to the sleeve end 32, the connecting part 41 can drive the crimping part 42 connected to the connecting part 41 to move near the sleeve end 32. Based on this:
[0036] When the pressure part 42 is in the second position, the distance between the two points with the largest distance in the orthographic projection of the pressure part 42 on the target plane is small, that is, the maximum width of the pressure part 42 parallel to the target plane is small, so that the fixing ring 2 can pass through the pressure part 42 (during this process, the pressure part 42 passes through the space surrounded by the fixing ring 2) and be sleeved on the outside of the fixing post 3 from the sleeve end 32 of the fixing post 3. It is also convenient for the fixing ring 2 sleeved on the outside of the fixing post 3 to pass through the pressure part 42 and be removed from the fixing post 3 from the sleeve end 32 of the fixing post 3. That is, the pressure part 42 allows the fixing ring 2 to be removed from the fixing post 3.
[0037] When the pressure part 42 is in the first position, the distance between the two points with the largest distance in the orthographic projection of the pressure part 42 on the target plane is larger, that is, the maximum width of the pressure part 42 parallel to the target plane is larger, so that the fixing ring 2 sleeved on the fixing post 3 is located between the pressure part 42 and the mounting surface 71, that is, the pressure part 42 restricts the fixing ring 2 from detaching from the fixing post 3.
[0038] For example, when the pressure part 42 is in the first position, the specific position and angle of the pressure part 42 relative to the fixing post 3 are as follows: Figure 4 As shown, at this time, the distance between the two points with the largest distance in the orthographic projection of the pressing part 42 on the target plane is equal to Figure 4 The spacing indicated by the dotted double arrow 'm' in the diagram represents the specific position and angle of the pressure part 42 relative to the fixed post 3 when the pressure part 42 is in the second position. Figure 4 As shown, this is the result of rotating 90 degrees relative to the fixed post 3 in the direction indicated by arrow b. At this point, the distance between the two points with the largest distance in the orthographic projection of the pressing part 42 on the target plane is equal to... Figure 4 The spacing indicated by the dashed double arrow n in the middle is from... Figure 4 As can be seen, the spacing indicated by m is greater than the spacing indicated by n. That is, when the pressing part 42 is in the first position, the distance between the two points with the largest distance in the orthographic projection of the pressing part 42 on the target plane is greater than the distance between the two points with the largest distance in the orthographic projection of the pressing part 42 on the target plane when the pressing part 42 is in the second position. It should be noted that in Figure 4 In the wire fixing device shown, the spacing indicated by n is not only smaller than the spacing indicated by m, but the spacing indicated by n is also smaller than the spacing indicated by m. Figure 4The sum of the spacing indicated by the dotted double arrow h in the middle is also less than the inner diameter of the fixing ring 2, so that when the pressing part 42 is in the second position, the fixing ring 2 can be dislodged from the fixing post 3 through the pressing member (i.e. the pressing member passes through the space surrounded by the fixing ring 2 from the fixing ring 2).
[0039] In this embodiment, by setting the connecting part 41 to be rotatably connected to the sleeve end 32, and setting the distance between the two points with the largest distance in the orthographic projection of the pressing part 42 on the target plane in the first position and the second position to be different, the pressing part 42 can allow or prevent the fixing ring 2 from detaching from the fixing post 3. The structure is simple and easy to operate.
[0040] In one possible implementation, such as Figure 4 As shown, the pressure part 42 is connected to a handle 5, which can be a fixed connection or the like.
[0041] In one specific implementation, such as Figure 4 As shown, the crimping part 42 includes a first crimping end 421 and a second crimping end 422. At least a portion of the connecting part 41 connects between the first crimping end 421 and the second crimping end 422. This connection can be a fixed connection or the like. When the fixing ring 2 is fitted onto the crimping post and the crimping part 42 is in the first position, the first crimping end 421 and the second crimping end 422 are respectively opposite to the annular surface of the fixing ring 2 away from the connecting end 31. At this time, the first crimping end 421 and the second crimping end 422 can abut against the annular surface, or there can be a gap between them. This embodiment does not limit this. During the process of the fixing ring 2 being fitted onto the crimping post and the crimping part 42 being moved from the first position to the second position by the connecting part 41... The first pressing end 421 moves toward the connecting end 31 of the fixing post 3, and the second pressing end 422 moves away from the connecting end 31 of the fixing post 3, so that the first pressing end 421 squeezes the fixing ring 2 to deform (the fixing ring 2 has a certain elasticity) until the first pressing end 421 is located in the space surrounded by the fixing ring 2, and the second pressing end 422 is located on the side of the fixing ring 2 away from the connecting end 31. Then, when the fixing ring 2 is sleeved on the pressing post and the pressing part 42 is in the second position, the first pressing end 421 is located in the space surrounded by the fixing ring 2, and the second pressing end 422 is located on the side of the fixing ring 2 away from the connecting end 31.
[0042] Based on this, the handle 5 is connected to the side of the second pressure end 422 away from the aforementioned at least part of the connecting part 41, and this connection can be a fixed connection or the like.
[0043] It should be noted that the size of the handle 5 is also smaller than the size of the space enclosed by the fixing ring 2, that is, the handle 5 can also pass through the fixing ring 2, so that when the fixing post 3 is fitted onto the fixing ring 2 or when it is dislodged from the fixing post 3, the handle 5 will also pass through the fixing ring 2.
[0044] In this embodiment, the operator can hold the handle 5 to control the handle 5 to drive the connecting part 41 to rotate relative to the fixed post 3 through the pressing part 42. Thus, the rotation of the connecting part 41 relative to the fixed post 3 can be achieved with less effort.
[0045] In one possible implementation, such as Figure 4 As shown, the connecting part 41 is connected to a damping member. When the pressing part 42 is in the first position, the damping member restricts the rotation of the connecting part 41 relative to the fixed post 3 by abutting against the fixed post 3 or against a structure fixedly connected to the fixed post 3.
[0046] or,
[0047] The fixed post 3 is connected to a damping element. When the pressure part 42 is in the first position, the damping element restricts the rotation of the connecting part 41 relative to the fixed post 3 by abutting against the connecting part 41 or against the structure that is fixedly connected to the connecting part 41.
[0048] Therefore, by setting a damping element, when the wire clamping part 42 is in the first position, the damping element can dampen the rotation of the connecting part 41 relative to the damping element, thereby reducing the possibility that the connecting part 41 rotates relative to the fixing post 3 when the wire fixing device fixes the wire 1, causing the fixing ring 2 to fall off the fixing post 3, so that the connection between the first fixing device and the wire 1 is more stable when the wire fixing device fixes the wire 1.
[0049] In one possible implementation, such as Figure 4 and Figure 5 As shown, the damping element includes a protrusion 411. If the damping element is connected to the connecting part 41, a groove 61 is provided on the connecting part 41 and the protrusion 411, and on the fixed post 3 or the structure fixedly connected to the fixed post 3. If the damping element is connected to the fixed post 3, a groove 61 is provided on the fixed post 3 and the protrusion 411, and on the connecting part 41 or the structure fixedly connected to the connecting part 41. When the pressing part 42 is in the first position, the protrusion 411 is engaged in the groove 61 so that the protrusion 411 abuts against the structure with the groove 61 through the groove 61. When the pressing part 42 is in the second position, the protrusion 411 is dislodged from the groove 61. Optionally, during the process of the pressing part 42 moving from the first position to the second position, the protrusion 411 can be squeezed and deformed (the protrusion 411 has a certain elasticity) until it is dislodged from the groove 61.
[0050] In this embodiment, when the wire pressing part 42 is in the first position, the protrusion 411 can be engaged in the groove 61. When the wire pressing part 42 moves from the first position to the second position, the protrusion 411 can move from inside the groove 61 to outside the groove 61. Therefore, when the wire pressing part 4 is in the first position, compared with the damping part abutting on the plane, the protrusion 411 being engaged in the groove 61 can make the damping of the connecting part 41 relative to the damping part greater, thereby further reducing the possibility that the connecting part 41 rotates relative to the fixing post 3 when the wire fixing device fixes the wire 1, causing the fixing ring 2 to fall off the fixing post 3, so that the connection between the wire fixing device and the wire 1 is more stable when the wire fixing device fixes the wire 1.
[0051] In one possible implementation, such as Figure 4 and Figure 5 As shown, the protrusion 411 is connected to the connecting part 41, and the fixing post 3 is provided with a locking post 6. The groove 61 is opened at the end of the locking post 6 away from the sleeve end 32.
[0052] In one specific embodiment, the connecting part 41 can be in the shape of a circular plate. The axis of rotation of the connecting part 41 relative to the fixed post 3 can be perpendicular to the circular surface in the outer surface of the connecting part 41 and pass through the center of the circular surface in the outer surface of the connecting part 41. The protrusion 411 is fixedly connected to the side surface between the two circular surfaces in the outer surface of the connecting part 41. A cavity is opened in the fixed post 3. The locking post 6 is fixedly connected in the cavity in the fixed post 3. The groove 61 is opened at the end of the locking post 6 away from the sleeve end 32.
[0053] In this embodiment, when the wire pressing part 42 is in the first position, the protrusion 411 abuts against the locking post 6 through the groove 61 inside the fixing post 3, so that the wire pressing part 42 is locked on the sleeve end 32. Thus, the setting of the protrusion 411 and the locking post 6 can make the external shape of the wire fixing device more concise and beautiful, and can also reduce the wear rate of the protrusion 411 and the locking post 6, and extend the service life of the wire fixing device.
[0054] In one possible implementation, such as Figure 3 and Figure 4 As shown, along the target direction (target direction as shown) Figure 4 As shown by arrow a in the diagram, the area enclosed by the outer contour of the cross section of the fixed column 3 perpendicular to the target direction gradually increases, and the target direction is the direction from the sleeve end 32 to the connecting end 31.
[0055] Therefore, the sleeve end 32 of the fixing post 3 is thinner, so that the fixing ring 2 can be sleeved on the outside of the fixing post 3 through the sleeve end 32. The connecting end 31 of the fixing post 3 is thicker, so that the fixing ring 2 can be stuck above the end face of the connecting end 31 of the fixing post 3, thereby reducing the wear of the mounting surface 71 on the annular surface of the fixing ring 2 near the mounting surface 71.
[0056] In one possible implementation, such as Figure 1 and Figure 2 As shown, the connecting end 31 is connected to a connecting seat 311 for detachable connection with the mounting surface 71 of the fixed post 3. For example, the connecting end 31 of the fixed post 3 is fixedly connected to the connecting seat 311, and the connecting seat 311 is threaded with bolts or screws to facilitate detachable connection between the connecting seat 311 and the mounting surface 71.
[0057] like Figure 1 and Figure 2 As shown, the underwater cleaning robot provided in this embodiment includes the aforementioned wire fixing device and battery sealing chamber 7. A battery is disposed inside the battery sealing chamber 7, and a terminal block 8 is disposed on one side of the battery sealing chamber 7. The interior of the terminal block 8 is connected to the interior of the battery sealing chamber 7. One end of the battery terminal block 1 is connected to the battery through the terminal block 8. Based on this, the mounting surface 71 of the fixing post 3 is the side of the battery sealing chamber 7 where the terminal block 8 is disposed. The fixing ring 2 is connected to the battery terminal block 1. The specific connection method between the fixing ring 2 and the terminal block 1 has been described above, and will not be repeated here in this embodiment.
[0058] Therefore, the wire fixing device can reduce the stress transmitted along the wire 1 to the connection between the wire 1 and the terminal block 8, improve the connection reliability between the wire 1 and the terminal block 8, and thus improve the connection reliability between the wire 1 and the battery.
[0059] In one possible implementation, such as Figure 1 and Figure 2 As shown, the distance between the fixed post 3 and the terminal block 8 is less than the preset distance. The preset distance can be a non-fixed value. For example, the preset distance is related to the size of the mounting surface 71 of the battery sealing chamber 7. The larger the mounting surface 71 is, the larger the preset distance is. The smaller the mounting surface 71 is, the smaller the preset distance can be. The preset distance can be a fixed value, such as 1 to 30 centimeters. The specific value of the preset distance is not limited in the embodiments of this application.
[0060] Therefore, reducing the distance between the fixing post 3 and the terminal block 8 allows the wire fixing device to fix the wire 1 closer to the terminal block 8, which can further reduce the stress transmitted along the wire 1 to the connection between the wire 1 and the terminal block 8, thereby further improving the reliability of the connection between the wire 1 and the battery.
[0061] It should be noted that the underwater cleaning robot provided in this application embodiment is based on the line fixing device provided in the foregoing embodiments and has the beneficial effects of the foregoing line fixing device embodiments, which will not be repeated here.
