Description

Technical Field

[0001] This invention relates to the field of power maintenance technology, and more specifically, to a power connection component and a power connection device for power transmission and distribution lines having the same. Background Technology

[0002] When 10kV transmission and distribution lines are under maintenance due to construction or faults, they cannot continuously supply power to users. To avoid prolonged power outages, a backup power source is temporarily connected to the non-maintenance section of the transmission and distribution line to replace the original power source and supply power to users.

[0003] In related technologies, the backup power supply transmission line is connected to the non-maintenance section line by manually operating the clamp at high altitude, or by manually operating the insulating rod on the ground and using the clamp set at the upper end of the insulating rod to connect the backup power supply transmission line to the non-maintenance section line. Specifically, the clamp is clamped on the non-maintenance section line by two oppositely arranged clamping plates, and the two clamping plates are electrically connected to the backup power supply transmission line.

[0004] However, the clamps in the related technology that are installed on lines not under maintenance are prone to loosening and falling off. Summary of the Invention

[0005] This invention provides a power connection component and a power connection device for power transmission and distribution lines having the same, in order to solve the problem in related technologies that the clamps installed on non-maintenance sections of the line are prone to loosening and falling off.

[0006] According to one aspect of the present invention, a power-connecting assembly is provided, comprising: a power-connecting hook with an opening facing downward; an operating member movably disposed on the power-connecting hook; a clamping assembly including a driven link and a driving link disposed at an acute angle, the upper end of the driven link being hinged to the power-connecting hook, the lower end of the driven link being hinged to the lower end of the driving link, the upper end of the driving link being hinged to the operating member, the operating member driving the lower end of the driven link to swing out via the driving link; and a locking member disposed between the operating member and the power-connecting hook, the locking member having a locked state that restricts the movement of the operating member relative to the power-connecting hook and an unlocked state that allows the operating member to move relative to the power-connecting hook.

[0007] Furthermore, the locking element includes: a plurality of reverse teeth arranged in a vertical direction on the power hook; and elastic teeth disposed on the operating element. The elastic teeth have an initial state of engaging with the reverse teeth and a deformed state of separating from the reverse teeth. When the elastic teeth are in the initial state, the reverse teeth can restrict the elastic teeth from moving upward relative to the reverse teeth.

[0008] Furthermore, the operating component includes: a push rod, which is movably mounted on the electric hook, with its upper end hinged to the upper end of the active connecting rod, and an elastic tooth mounted on the operating component; a base, which is movably mounted on the lower end of the push rod; and a support column, which is mounted on the base, with its upper end able to contact the elastic tooth to apply a force to the elastic tooth to switch it from the initial state to the deformed state.

[0009] Furthermore, the elastic teeth gradually tilt towards the inverted teeth in an upward direction.

[0010] Furthermore, the support includes: a first link, the first end of which is hinged to the base; and a second link, the second end of which is hinged to the first end of the first link, and the second end of the second link is hinged to an elastic tooth.

[0011] Furthermore, the push rod has a receiving groove extending in the vertical direction on the side facing the reverse tooth. The elastic tooth is set on the groove wall facing the reverse tooth of the receiving groove. When the elastic tooth is in the initial state, the elastic tooth can protrude out of the receiving groove. When the elastic tooth is in the deformed state, the elastic tooth is flush with the receiving groove or retracts into the receiving groove. The support column is movably set in the receiving groove.

[0012] Furthermore, the operating components also include: a connecting wire, one end of which passes through the base and the other end of which is electrically connected to a backup power supply; and an elastic conductive element, including a first conductive element and a second conductive element, wherein the connecting hook and the connecting wire are electrically connected through the first conductive element, and the driven linkage and the connecting wire are electrically connected through the second conductive element.

[0013] Furthermore, a first guide rail extending in the vertical direction is provided between the base and the push rod; and / or, a guide hole extending in the vertical direction is provided on the electric hook, the upper end of the push rod is movably inserted into the guide hole along the extension direction of the guide hole, and multiple counter-teeth are provided on the hole wall of the guide hole.

[0014] Furthermore, the power connection assembly also includes a drive arm, the first end of which has a fixed mounting portion, and the second end of which has an operating notch that can be interference-fitted with the operating component.

[0015] According to another aspect of the present invention, a power transmission and distribution line connection device is provided, which includes the connection components provided above.

[0016] According to the technical solution of this invention, the power connection assembly includes a power connection hook, an operating component, a clamping component, and a locking component. When power is connected using the power connection assembly, the power connection hook is electrically connected to the backup power supply. The locking component is first switched to the unlocked state, and the operating component is gripped to hang the power connection hook on the wire with the insulation layer stripped. The wire is located in the opening of the power connection hook. The operating component is pulled downward relative to the connection hook, causing the upper end of the active connecting rod to swing downward, and causing the lower end of the driven connecting rod to swing out in the direction of narrowing the opening of the power connection hook. The wire is clamped by the driven connecting rod and the power connection hook to clamp the wire. The locking component is then switched to the locked state to restrict the movement of the operating component relative to the power connection hook and prevent the clamping component from loosening. When removing the connection assembly from the conductor, first switch the locking mechanism to the unlocked state, grasp the operating mechanism, and move the operating mechanism upward relative to the connection hook. This causes the operating mechanism to swing the upper end of the driving linkage upward, and the lower end of the driven linkage to swing back towards widening the opening of the connection hook. This releases the conductor from the conductor via the driven linkage and the connection hook. Then, remove the connection hook from the conductor, separating the connection assembly from the conductor. Therefore, when the driven linkage and the connection hook clamp and press the conductor, the locking mechanism, in its locked state, restricts the movement of the operating mechanism relative to the connection hook, thus preventing the clamping assembly from loosening and the connection assembly from falling off the conductor.

[0030] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. 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.

[0031] like Figures 1 to 6 As shown, this embodiment of the invention provides a power connection assembly, which includes a power connection hook 61, an operating member 62, a clamping assembly 63, and a locking member 64. The power connection hook 61 has its opening facing downwards. The operating member 62 is movably mounted on the power connection hook 61. The clamping assembly 63 includes a driven link 631 and a driving link 632 arranged at an acute angle. The upper end of the driven link 631 is hinged to the power connection hook 61, and the lower end of the driven link 631 is hinged to the lower end of the driving link 632. The upper end of the driving link 632 is hinged to the operating member 62. The operating member 62 drives the lower end of the driven link 631 to swing out through the driving link 632. The locking member 64 is disposed between the operating member 62 and the power connection hook 61. The locking member 64 has a locked state that restricts the movement of the operating member 62 relative to the power connection hook 61 and an unlocked state that allows the operating member 62 to move relative to the power connection hook 61.

[0032] In the application embodiment of the power connection assembly, when power is connected, the power connection hook 61 is electrically connected to the backup power supply. The locking member 64 is first switched to the unlocked state, and the operating member 62 is grasped to hang the power connection hook 61 on the wire 30 with the insulation layer stripped. The wire 30 is located in the opening of the power connection hook 61. The operating member 62 is pulled down relative to the connection hook, so that the operating member 62 drives the upper end of the active connecting rod 632 to swing down, and causes the lower end of the driven connecting rod 631 to swing out in the direction of narrowing the opening of the power connection hook 61. The wire 30 is clamped by the driven connecting rod 631 and the power connection hook 61 to press the wire 30. The locking member 64 is switched to the locked state to restrict the movement of the operating member 62 relative to the power connection hook 61 and prevent the pressing component 63 from loosening. When removing the connection assembly from the wire 30, the locking member 64 is first switched to the unlocked state, the operating member 62 is gripped, and the operating member 62 is moved upward relative to the connection hook. This causes the operating member 62 to drive the upper end of the active connecting rod 632 to swing upward, and causes the lower end of the driven connecting rod 631 to swing back towards the direction of widening the opening of the connection hook 61. Thus, the driven connecting rod 631 and the connection hook 61 release the wire 30, and then the connection hook 61 is removed from the wire 30, separating the connection assembly from the wire 30. Therefore, when the driven connecting rod 631 and the connection hook 61 clamp and press the wire 30, the locking member 64, which is in the locked state, restricts the movement of the operating member 62 relative to the connection hook 61, thereby preventing the pressing assembly 63 from loosening and preventing the connection assembly from falling off the wire 30.

[0033] To avoid workers having to climb the tower to operate the equipment, workers can operate the insulating rod from the ground and use it to grip the operating component 62 to operate the power connection assembly, or they can use a robotic arm to grip the operating component 62 to operate the power connection assembly.

[0034] like Figures 1 to 3 As shown, the locking member 64 includes an elastic tooth 642 and a plurality of reverse teeth 641. The plurality of reverse teeth 641 are arranged in a vertical direction on the electric hook 61. The elastic tooth 642 is disposed on the operating member 62. The elastic tooth 642 has an initial state in which it engages with the reverse teeth 641 and a deformed state in which it separates from the reverse teeth 641. When the elastic tooth 642 is in the initial state, the reverse teeth 641 can restrict the elastic tooth 642 from moving upward relative to the reverse teeth 641.

[0035] Specifically, when the power connection assembly is used and the wire 30 is located in the opening of the power connection hook 61, the elastic tooth 642 is switched to the initial state. The operating member 62 is pulled down relative to the wire hook, and the elastic tooth 642 can move down relative to the reverse tooth 641. This causes the operating member 62 to move down relative to the wire hook, and the lower end of the driven link 631 swings out in the direction of narrowing the opening of the power connection hook 61. The driven link 631 and the power connection hook 61 clamp the wire 30. Since the reverse tooth 641 can restrict the elastic tooth 642 from moving up relative to the reverse tooth 641, the operating member 62 is prevented from retracting upward relative to the power connection hook 61, thus preventing the clamping assembly 63 from loosening. When the power connection assembly is removed from the wire 30, the elastic tooth 642 is switched to the deformed state, thereby separating the reverse tooth 641 and the elastic tooth 642. The reverse tooth 641 no longer restricts the elastic tooth 642 from moving upward relative to the reverse tooth 641. At this time, the operating member 62 moves upward relative to the connection hook, causing the driven link 631 and the power connection hook 61 to release the wire 30 and separate the power connection assembly and the wire 30.

[0036] like Figure 1 and Figure 2 As shown, the operating component 62 includes a push rod 621, a base 622, and a support column 623. The push rod 621 is movably mounted on the electric hook 61. The upper end of the push rod 621 is hinged to the upper end of the active connecting rod 632. An elastic tooth 642 is mounted on the operating component 62. The base 622 is movably mounted on the lower end of the push rod 621. The support column 623 is mounted on the base 622. The upper end of the support column 623 can contact the elastic tooth 642 to apply a force to the elastic tooth 642 to switch from the initial state to the deformed state.

[0037] The base 622 has a certain travel distance relative to the push rod 621. When the power connection component is used to connect to the power supply and the wire 30 is located in the opening of the power connection hook 61, the base 622 is pulled down, so that the elastic tooth 642 switches to the initial state. When the downward movement of the base 622 relative to the push rod 621 reaches the travel distance limit, the base 622 drives the push rod 621 to move downward relative to the power connection hook 61. The upper end of the push rod 621 drives the upper end of the active connecting rod 632 to swing downward, and the lower end of the driven connecting rod 631 swings out in the direction of narrowing the opening of the power connection hook 61. The driven connecting rod 631 and the power connection hook 61 clamp the wire 30. When the power connection assembly is removed from the wire 30, the base 622 is pulled upward so that the upper end of the support column 623 contacts the elastic tooth 642, thereby applying a force to the elastic tooth 642 to switch from the initial state to the deformed state. The elastic tooth 642 switches to the deformed state, and the reverse tooth 641 no longer restricts the elastic tooth 642 from moving upward relative to the reverse tooth 641. When the upward movement of the base 622 relative to the push rod 621 reaches the travel limit, the base 622 drives the push rod 621 to move upward relative to the power connection hook 61. The upper end of the push rod 621 drives the upper end of the active connecting rod 632 to swing upward, so that the driven connecting rod 631 and the power connection hook 61 release the wire 30 and separate the power connection assembly and the wire 30.

[0038] Specifically, the structure of the support column 623 includes the following two embodiments:

[0039] (1) The support column 623 includes a support rod, the lower end of which is fixed to the base 622, and the upper end of which can abut against the elastic tooth 642 to apply a force to the elastic tooth 642 to switch from the initial state to the deformed state.

[0040] (2) The support 623 includes a first link and a second link. The first end of the first link is hinged to the base 622, the second end of the first link is hinged to the first end of the second link, and the second end of the second link is hinged to the elastic tooth 642.

[0041] like Figure 2 As shown, the elastic tooth 642 gradually tilts towards the inverted tooth 641 in the direction from bottom to top. It contacts the elastic tooth 642 at the upper end of the support column 623. When the support column 623 applies a force to the elastic tooth 642 to switch from the initial state to the deformed state, it facilitates the upward deformation of the end of the elastic tooth 642 facing the inverted tooth 641, thereby facilitating the switch of the elastic tooth 642 from the initial state to the deformed state.

[0042] In this embodiment, the support column 623 includes a first link and a second link. The first end of the first link is hinged to the base 622, the second end of the first link is hinged to the first end of the second link, and the second end of the second link is hinged to the elastic tooth 642. Specifically, pulling the base 622 upward relative to the push rod 621 causes the first and second connecting rods to unfold and pull the elastic tooth 642 upward, applying a force to the elastic tooth 642 to switch it from its initial state to its deformed state. Conversely, pulling the base 622 downward relative to the push rod 621 causes the first and second connecting rods to unfold and pull the elastic tooth 642 downward, applying a force to the elastic tooth 642 to switch it from its deformed state to its initial state. This ensures that even if the elastic tooth 642 ages or loses its elasticity, the support column 623 can still ensure that the elastic tooth 642 switches from its deformed state to its initial state when the base 622 is pulled downward relative to the push rod 621, thus improving the reliability of the elastic tooth 642 switching between its deformed and initial states.

[0043] like Figure 2 As shown, the push rod 621 has a receiving groove 6211 extending vertically on the side facing the reverse tooth 641. An elastic tooth 642 is disposed on the groove wall of the receiving groove 6211 facing the reverse tooth 641. When the elastic tooth 642 is in its initial state, it protrudes from the receiving groove 6211. When the elastic tooth 642 is in its deformed state, it lies flush with the receiving groove 6211 or retracts into it. The support column 623 is movably disposed within the receiving groove 6211. By disposing the support column 623 and the elastic tooth 642 within the receiving groove 6211, a compact structure and convenient installation are achieved while ensuring reliable meshing between the elastic tooth 642 and the reverse tooth 641 in the initial state.

[0044] like Figure 1 As shown, the operating component 62 also includes a connecting wire 65 and an elastic conductive element 66. One end of the connecting wire 65 passes through the base 622, and the other end of the connecting wire 65 is electrically connected to a backup power supply. The elastic conductive element 66 includes a first conductive element 661 and a second conductive element 662. The connecting hook 61 and the connecting wire 65 are electrically connected through the first conductive element 661, and the driven link 631 and the connecting wire 65 are electrically connected through the second conductive element 662. During the up-and-down movement of the base 622 relative to the connecting hook 61, the deformation of the elastic conductive element 66 can maintain the electrical connection between the connecting hook 61 and the connecting wire 65 through the first conductive element 661, and maintain the electrical connection between the driven link 631 and the connecting wire 65 through the second conductive element 662.

[0045] In this embodiment, a first guide rail extending in the vertical direction is provided between the base 622 and the push rod 621. The first guide rail guides the vertical movement of the base 622 relative to the push rod 621, thereby improving the stability and reliability of the movement of the base 622 relative to the push rod 621.

[0046] In this embodiment, the power hook 61 is provided with a guide hole extending in the vertical direction. The upper end of the push rod 621 extends movably into the guide hole along its extension direction. Multiple countersunk teeth 641 are disposed on the wall of the guide hole. The guide hole guides the vertical movement of the push rod 621 relative to the power hook 61, improving the smoothness and reliability of the movement of the push rod 621 relative to the power hook 61. Furthermore, by disposing of multiple countersunk teeth 641 on the wall of the guide hole, impurities from the external environment can be prevented from affecting the engagement between the countersunk teeth 641 and the elastic teeth 642, thus improving the reliability of the locking member 64.

[0047] like Figure 1 , Figure 5 as well as Figure 6 As shown, the power connection assembly also includes a drive arm 67. The first end of the drive arm 67 has a fixed mounting portion 671, and the second end of the drive arm 67 is provided with an operating notch 672. The operating notch 672 can be interference-fitted with the operating member 62. The interference fit between the operating notch 672 and the operating member 62 means that when the operating member 62 is located within the operating notch 672, the operating notch 672 is opened, allowing the drive arm 67 to clamp the operating member 62 through the operating notch 672. The interference fit between the operating notch 672 and the operating member 62 prevents the operating member 62 from detaching from the operating notch 672 when the drive arm 67 and the operating member 62 are separated without external force. When separating the drive arm 67 and the operating member 62, the frictional force between the operating member 62 and the operating notch 672 must be overcome.

[0048] Specifically, a drive arm 67 is mounted using a fixed mounting part 671. The drive arm 67 can rotate around the fixed mounting part 671. The rotation axis of the drive arm 67 is perpendicular to the vertical direction. When connected to power using the power connection assembly, the operating notch 672 is interference-fitted with the operating member 62. Figure 1In the orientation, rotating the drive arm 67 clockwise causes the connection hook 61 to be hooked onto the stripped wire 30. Continuing to rotate the drive arm 67 clockwise pulls the base 622 downwards, causing the elastic tooth 642 to switch to its initial state. When the downward movement of the base 622 relative to the push rod 621 reaches its travel limit, the base 622 drives the push rod 621 to move downwards relative to the connection hook 61 until the driven link 631 and the connection hook 61 clamp the wire 30. Continuing to rotate the drive arm 67 clockwise overcomes the friction between the operating member 62 and the operating notch 672, separating the drive arm 67 and the operating member 62. When removing the connection assembly from the wire 30, Figure 1 In the correct orientation, the drive arm 67 is rotated counterclockwise to overcome the friction between the operating member 62 and the operating notch 672, so that the drive arm 67 clamps the operating member 62 through the operating notch 672. Continuing to rotate the drive arm 67 counterclockwise, the drive arm 67 moves the base 622 upward. The base 622, through the support column 623, causes the elastic tooth 642 to switch from a deformed state to its initial state. When the upward movement of the base 622 relative to the push rod 621 reaches the travel limit, the base 622 drives the push rod 621 to move upward relative to the electrical hook 61 until the driven link 631 and the electrical hook 61 release the wire 30. Continuing to rotate the drive arm 67 counterclockwise, the electrical hook 61 is removed from the wire 30, separating the electrical connection assembly and the wire 30.

[0049] like Figure 4As shown, this embodiment of the invention provides a power transmission and distribution line connection device, which includes the connection components provided above. When using the connection components to connect power, the connection hook 61 is electrically connected to a backup power source. The locking member 64 is first switched to the unlocked state, and the operating member 62 is grasped to hang the connection hook 61 on the stripped insulation layer of the conductor 30. The conductor 30 is located within the opening of the connection hook 61. The operating member 62 is pulled downwards relative to the connection hook, causing the upper end of the active connecting rod 632 to swing downwards, and the lower end of the driven connecting rod 631 to swing outwards towards narrowing the opening of the connection hook 61. The conductor 30 is clamped by the driven connecting rod 631 and the connection hook 61 to press the conductor 30 firmly. The locking member 64 is then switched to the locked state to restrict the movement of the operating member 62 relative to the connection hook 61, preventing the pressing component 63 from loosening. When removing the connection assembly from the wire 30, the locking member 64 is first switched to the unlocked state, the operating member 62 is gripped, and the operating member 62 is moved upward relative to the connection hook. This causes the operating member 62 to drive the upper end of the active connecting rod 632 to swing upward, and causes the lower end of the driven connecting rod 631 to swing back towards the direction of widening the opening of the connection hook 61. Thus, the driven connecting rod 631 and the connection hook 61 release the wire 30, and then the connection hook 61 is removed from the wire 30, separating the connection assembly from the wire 30. Therefore, when the driven connecting rod 631 and the connection hook 61 clamp and press the wire 30, the locking member 64, which is in the locked state, restricts the movement of the operating member 62 relative to the connection hook 61, thereby preventing the pressing assembly 63 from loosening and preventing the connection assembly from falling off the wire 30.

[0050] like Figure 4 As shown, the power transmission and distribution line connection device can be installed on the conductor 30. The device also includes a frame 10, a traveling member 20, an insulation removal member 40, an insulation repair member 50, and upper and lower line members 70. The traveling member 20 is mounted on the frame 10 and can cooperate with the conductor 30 to move the frame 10 along the conductor 30. The insulation removal member 40 and the insulation repair member 50 are mounted on the frame 10. The power transmission and distribution line connection device has a removal working state, a repair working state, and a free-moving state. When the power transmission and distribution line connection device is in the removal working state, the insulation removal member 40... The insulation layer repair component 50 is used in conjunction with the conductor 30 to remove the insulation layer of the conductor 30. When the power transmission and distribution line connection device is in the repair working state, the insulation layer repair component 50 is used in conjunction with the conductor 30 to repair the insulation layer of the conductor 30. When the power transmission and distribution line connection device is in the free walking state, both the insulation layer removal component 40 and the insulation layer repair component 50 are separated from the conductor 30. The connection component 60 is set on the frame 10. The connection component 60 has a connection state that is connected to the conductor 30 and a de-energized state that is disconnected from the conductor 30. The upper and lower wire components 70 are vertically and vertically adjustable on the frame 10. The upper end of the upper and lower wire components 70 is provided with a wire connection part.

[0051] In this process, the power connection device is installed on the conductor 30. The traveling member 20, in conjunction with the conductor 30, moves the frame 10 along the conductor 30. The insulation removal member 40, in conjunction with the conductor 30, removes the insulation layer. Then, both the insulation removal member 40 and the insulation repair member 50 separate from the conductor 30. The frame 10 moves along the conductor 30, aligning the power connection component 60 on the frame 10 with the portion of the conductor 30 where the insulation layer has been removed. This switches the power connection component 60 to a connected state with the conductor 30, thus connecting the backup power supply and the conductor 30. After the backup power supply is deactivated, the power connection component 60 is switched to a disconnected state from the conductor 30. The frame 10 moves along the conductor 30, and the insulation repair member 50, in conjunction with the conductor 30, repairs the insulation layer of the conductor 30 after it has been removed. Therefore, the process of stripping the insulation layer of conductor 30, connecting the stripped portion of conductor 30 to a backup power supply, and repairing the insulation layer of conductor 30 after the backup power supply is used is integrated into an automated tool, eliminating the need for workers to operate on the tower and improving efficiency and safety.

[0052] Furthermore, workers on the ground use insulating rods to connect the conductor connection part to the overhead conductor 30, and retract the upper and lower wire components 70 to use the upper and lower wire components 70 to drive the frame 10 to rise, so that the frame 10 can be transported to the overhead conductor 30 without workers having to go up the tower to operate.

[0053] like Figure 4 As shown, the power transmission line connection device also includes a rotating cylinder 81 and a rotating drive component 82. The rotating cylinder 81 extends along the conductor 30 and is rotatably mounted on the frame 10 around its own axis. The rotating cylinder 81 is provided with conductor passages 811 that are parallel to the conductor 30 and extend to both ends of the rotating cylinder 81. The insulation layer repair component 50 and the insulation layer removal component 40 are both mounted on the rotating cylinder 81. The rotating drive component 82 is located between the frame 10 and the rotating cylinder 81. The rotating drive component 82 is drivenly connected to the rotating cylinder 81 to drive the rotating cylinder 81 to rotate. The wire 30 is passed through the wire inlet 811 to allow the wire to enter the rotating cylinder 81. When the insulation removal component 40 is engaged with the wire 30, the rotating drive component 82 drives the rotating cylinder 81 to rotate and moves the frame 10 along the wire 30, thereby removing the insulation layer of the wire 30 using the insulation removal component 40. When the insulation repair component 50 is engaged with the wire 30, the rotating drive component 82 drives the rotating cylinder 81 to rotate and moves the frame 10 along the wire 30, thereby repairing the insulation layer of the wire 30 using the insulation repair component 50.

[0054] like Figure 4As shown, the power transmission line connection device also includes an electrical control box 90 mounted on the frame 10. The electrical control box 90 contains control components and power supply components. The power supply components are electrically connected to the traveling component 20, the insulation removal component 40, the insulation repair component 50, the upper and lower line components 70, the rotation drive component 82, and the control components to provide power.

[0055] Specifically, the fixed installation part 671 is connected to the frame 10.

[0056] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0057] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0058] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0059] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0060] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
