Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electrical equipment, and in particular to a guide rail buckle structure and a contactor system applied to a contactor. Background Art
[0002] Contactors are commonly used electrical appliances, usually used to control the switching of high-power electrical appliances or circuits. Contactors can convert control signals into mechanical motion to achieve the closing and disconnection of circuits.
[0003] The contactor is usually installed on the guide rail of the distribution box for use. During the installation of the contactor, the guide rail clamp block is needed to fix the contactor to the guide rail. However, in the prior art, the problem of the contactor falling off the guide rail often occurs because the guide rail clamp block is not firmly connected to the guide rail. Therefore, a guide rail buckle structure and a contactor system applied to the contactor are urgently needed. Utility Model Content
[0004] The present application provides a guide rail buckle structure and a contactor system applied to a contactor, which improve the installation stability of the contactor on the guide rail.
[0005] In the first aspect, the present application provides a guide rail buckle structure applied to a contactor, which is used to install the contactor on the guide rail, the housing of the contactor includes a first limiting surface and a locking surface, and the guide rail buckle structure includes: a guide rail block and an elastic rod. The guide rail block includes a push portion and a locking portion. The elastic rod includes two ends that are opposite to each other, both ends are against the first limiting surface, and the rest of the elastic rod except the two ends is used to be against the push portion.
[0006] The guide rail buckle structure is installed on the shell, and when the guide rail block does not move in the first direction, the elastic rod is located between the first limiting surface and the push portion, and the locking portion is located between the push portion and the locking surface. When the guide rail block moves in the first direction relative to the shell, the push portion can drive the remaining parts to move in the first direction, and the first limiting surface can limit the two ends from moving in the first direction, so that the elastic rod is deformed and stores energy. After the elastic rod is deformed and stores energy, when the guide rail block continues to move in the first direction, the locking portion can be engaged with the locking surface. The first direction is the direction away from the guide rail.
[0007] Through the above scheme, the present application sets an elastic rod in the guide rail buckle structure. When the guide rail buckle structure is installed on the shell and the guide rail block does not move in the first direction, the two ends of the elastic rod are against the first limit surface, and the rest of the elastic rod except the two ends are against the push portion. In this way, the elastic rod, the shell and the guide rail block can cooperate with each other, so that the guide rail block will not move in the first direction. At this time, the contactor is clamped on the guide rail. Since the force exerted by the shaking or bumping of the contactor is not enough to deform the elastic rod, the guide rail buckle structure will not be displaced, thereby reducing the probability of the contactor falling off the guide rail due to the loose guide rail buckle structure, increasing the service life of the contactor, and reducing the probability of the contactor falling off the guide rail. The maintenance cost of the contactor in the later stage can also be reduced.
[0008] In addition, through the above-mentioned configuration of the present application, when the guide rail block moves in the first direction relative to the housing, the push portion can drive the remaining parts of the elastic rod except the two ends to move in the first direction, and the first limiting surface can limit the two ends of the elastic rod, so that the elastic rod is deformed and stores energy. After the elastic rod is deformed, the guide rail block continues to move in the first direction, which can make the locking portion engage with the locking surface. In this way, without applying external force, the guide rail block can be stationary relative to the housing, realizing the automatic locking of the guide rail buckle structure and saving manpower.
[0009] After the guide rail buckle structure is automatically locked to the shell, when the contactor needs to be installed on the guide rail, it is only necessary to apply external force to the guide rail block to unlock the locking part and the locking surface. The elastic potential energy released by the elastic rod can drive the guide rail block to move toward the guide rail and clamp with the guide rail, thereby realizing the installation of the contactor on the guide rail with high installation efficiency.
[0010] In a possible design, the locking portion is configured as a first protrusion. When the guide rail block does not move in the first direction, the projection of the first protrusion in the first direction partially overlaps with the projection of the locking surface in the first direction, and a first guide surface is provided on one side of the first protrusion away from the push portion.
[0011] Through the above scheme, when the guide rail block has not moved in the first direction, the projection of the first protrusion in the first direction partially overlaps with the projection of the locking surface in the first direction. In this way, after the first protrusion moves in the first direction, the locking surface can limit the first protrusion. When the guide rail block moves in the first direction, it is necessary to slightly lift the end of the guide rail block away from the guide rail so that the first protrusion can be misaligned with the locking surface to avoid the locking surface from affecting the movement of the guide rail block. When the first protrusion is completely misaligned with the locking surface, put down the end of the guide rail block away from the guide rail. At this time, the locking surface can limit the first protrusion, thereby limiting the guide rail block.
[0012] In a possible design, the housing further includes a second limiting surface, and the guide rail block further includes a limiting portion. When the elastic rod releases energy to drive the guide rail block to move in the second direction to a preset position, the limiting portion can abut against the second limiting surface to limit the guide rail block from continuing to move in the second direction, which is opposite to the first direction.
[0013] With the above scheme, since the guide rail block needs to be driven by the elastic rod to move in the second direction during the process of the elastic rod releasing energy, but the elastic rod often releases a large amount of energy in an instant during the process of releasing energy, which will cause the guide rail block to move too far in the second direction, the setting of the limiting portion and the second limiting surface can limit the guide rail block when it moves in the second direction, thereby reducing the probability of the guide rail block moving excessively and falling off the shell when driven by the elastic rod. In addition, the setting of the second limiting surface can also buffer the movement of the guide rail block during the process of the guide rail block moving in the second direction, thereby reducing the probability of the guide rail and the guide rail block being damaged due to the direct impact of the guide rail block.
[0014] In a possible design, the housing is provided with two opposite limiting grooves, and the guide rail block is provided with limiting blocks on opposite sides of the two limiting grooves in the arrangement direction. The limiting blocks are at least partially located in the limiting grooves and can slide in the limiting grooves along the first direction and the second direction.
[0015] Through the above scheme, a limiting groove is provided on the housing, and a limiting block is provided on the guide rail block, so that the guide rail block can be limited in a direction away from the bottom of the slide groove, thereby reducing the probability of the guide rail block falling off the housing. The limiting block is at least partially located in the limiting groove, and can slide in the limiting groove along the first direction and the second direction. In this way, while the limiting groove limits the limiting block, it will not affect the movement of the guide rail block in the first direction and the second direction.
[0016] In a possible design, the guide rail block is provided with an operating portion, and the operating portion is used to cooperate with a tool.
[0017] Through the above scheme, an operating part is provided on the guide rail block, which can make it easier for operators to operate the guide rail block, and reduce the probability of problems such as the guide rail block being difficult to operate due to its small size, thereby affecting the installation of the contactor.
[0018] In a possible design, a mark is provided at a position of the guide rail clamping block near the locking portion, and the mark is used to indicate the position of the guide rail buckle structure relative to the housing, or the mark is used to indicate whether the contactor is installed on the guide rail.
[0019] Through the above scheme, a mark is provided at the position of the guide rail block near the locking part, and the mark can be used to indicate the state of the guide rail block, so that the operator can clearly know whether the guide rail block is correctly connected with the guide rail. If the mark can be clearly observed outside the shell, it can be indicated that the connection between the guide rail block and the guide rail is not complete, so the contactor can be reinstalled on the guide rail until the contactor can be firmly installed on the guide rail. In this way, the probability of the contactor falling off the guide rail due to the loose guide rail buckle structure is reduced, and the service life of the contactor is increased.
[0020] In a possible design, the identification includes a first mark and a second mark, and the first mark is farther away from the push portion than the second mark. When the guide rail buckle structure is installed on the housing and the guide rail block is not moved, or when the contactor is installed on the guide rail, the first mark is exposed outside the housing. When the guide rail block moves relative to the housing in a first direction so that the locking portion is engaged with the locking surface, the first mark and the second mark are both exposed outside the housing.
[0021] Through the above scheme, the marks are set as the first mark and the second mark respectively, so that the status display of the guide rail block can be more obvious, and the observation of the operator can be more convenient. When only the first mark is exposed outside the shell, it can be determined that the guide rail block is connected to the guide rail. If the first mark and the second mark are both exposed outside the shell, it can be determined that the guide rail block is in the energy storage state. If the first mark and part of the second mark are exposed outside the shell, it can be determined that the guide rail block is not completely connected to the guide rail. At this time, the contactor can be removed from the guide rail and reinstalled.
[0022] In a second aspect, the present application provides a contactor system, including a contactor and the guide rail snap-in structure mentioned in the first aspect, the housing of the contactor includes a slide groove, the guide rail snap-in structure is partially located in the slide groove, and can move in the slide groove.
[0023] Through the above scheme, the contactor system provided by the present application is provided with a guide rail buckle structure on the shell of the contactor. When the contactor is installed on the guide rail, the guide rail clamp block cooperates with the shell to fix the contactor on the guide rail, thereby reducing the probability of the contactor falling off the guide rail due to the loose guide rail buckle structure when the contactor shakes or is bumped during use, thereby increasing the service life of the contactor, and after reducing the probability of the contactor falling off the guide rail, the later maintenance cost of the contactor can also be reduced.
[0024] In a possible design, there are two first limiting surfaces, which are located on opposite sides of the slide slot. The first limiting surface includes a straight surface and a bent surface connected to each other, the bent surface is closer to the slide slot than the straight surface, and the bent surface is farther from the push portion than the straight surface.
[0025] Through the above solution, the first limiting surface is set as a straight surface and a bent surface connected to each other, which can reduce the resistance caused by the first limiting surface to the elastic rod when the elastic rod is deformed, thereby reducing the difficulty of operating the guide rail block.
[0026] The beneficial effects of the contactor system provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, which will not be described in detail here.

Figure 2 A schematic diagram of a partial structure of a shell provided in an embodiment of the present application at a certain viewing angle. Figure 3 A schematic diagram of a partial structure of a housing provided in an embodiment of the present application from another perspective. Figures 1 to 3 As shown, the present application provides a contactor system, including a contactor and a guide rail buckle structure, the housing 100 of the contactor includes a slide groove 150, the guide rail buckle structure is partially located in the slide groove 150, and can move in the slide groove 150.
[0055] The housing 100 is also provided with a guide rail mounting groove, which is connected to the slide groove 150 and is substantially perpendicular to the slide groove 150. The guide rail mounting groove is used to mount the guide rail, and the angle between the guide rail mounting groove and the slide groove 150 can be 90°, 88° or 85°, etc. The guide rail buckle structure is partially located in the slide groove 150, and one end of the guide rail buckle structure close to the guide rail mounting groove is used to abut the guide rail so that the contactor can be fixed on the guide rail.
[0056] The slide groove 150 can be integrally formed with the housing 100 when the housing 100 is formed, or the slide groove 150 can be provided on the housing 100 by carving or cutting after the housing 100 is formed. Similarly, the guide rail mounting groove can be integrally formed with the housing 100 when the housing 100 is formed, or the guide rail mounting groove can be provided on the housing 100 by carving or cutting after the housing 100 is formed.

[0058] The contactor system provided by the present application is provided with a guide rail buckle structure on the housing 100 of the contactor.

[0061] like Figures 4 to 11 As shown, the present application provides a guide rail buckle structure applied to a contactor, which is used to install the contactor on the guide rail. The housing 100 of the contactor includes a first limiting surface 110 and a locking surface 120. The guide rail buckle structure includes: a guide rail block 200 and an elastic rod 300. The guide rail block 200 includes a push portion 210 and a locking portion 220. The elastic rod 300 includes two ends in opposite positions, both of which are against the first limiting surface 110, and the rest of the elastic rod 300 except the two ends is used to be against the push portion 210.
[0062] The guide rail buckle structure is installed on the housing 100 , and when the guide rail block 200 does not move in the first direction OX, the elastic rod 300 is located between the first limiting surface 110 and the pushing portion 210 , and the locking portion 220 is located between the pushing portion 210 and the locking surface 120 .
[0063] When the guide rail block 200 moves in the first direction OX relative to the housing 100, the push portion 210 can drive the remaining parts to move in the first direction OX, and the first limit surface 110 can limit the two ends from moving in the first direction OX, so that the elastic rod 300 is deformed and stores energy. After the elastic rod 300 is deformed and stores energy, when the guide rail block 200 continues to move in the first direction OX, the locking portion 220 can be engaged with the locking surface 120. The first direction OX is the direction away from the guide rail.
[0064] The housing 100 is provided with a mounting groove at the slide groove 150, the mounting groove is substantially perpendicular to the slide groove 150, and the mounting groove is provided on the slide groove 150. The first limiting surface 110 may be the groove walls at both ends of the mounting groove, and the first limiting surface 110 faces the direction opposite to the first direction OX. The locking surface 120 may be the side wall of the housing 100, and the locking surface 120 may face the same direction as the first direction OX.
[0065] The elastic rod 300 may be a rod-shaped object made of a material having good elastic properties. The elastic rod 300 may be deformed when subjected to an external force and may return to its original shape when the external force is removed. The elastic rod 300 may be made of polyurethane, polytetrafluoroethylene or stainless steel. The elastic rod 300 includes two ends that are opposite to each other, and both ends of the elastic rod 300 may be located at both ends of the mounting groove, and both ends of the elastic rod 300 may abut against the first limiting surface 110.
[0066] The guide rail block 200 may be a slider structure disposed on the housing 100 .
[0067] The push portion 210 may be a protruding structure provided on the guide rail block 200. The push portion 210 may be integrally formed with the guide rail block 200, or the push portion 210 may be separately formed with the guide rail block 200 and then assembled. The push portion 210 is used in conjunction with the elastic rod 300, and the rest of the elastic rod 300 except the two ends is against the push portion 210, so that the guide rail block 200 can clamp the guide rail.
[0068] The locking portion 220 may be a protruding structure provided on the guide rail block 200. The locking portion 220 may be integrally formed with the guide rail block 200, or the locking portion 220 may be separately formed with the guide rail block 200 and then assembled. The locking portion 220 cooperates with the locking surface 120 to limit the movement of the guide rail block 200.
[0069] In summary, the present application sets an elastic rod 300 in the guide rail buckle structure. When the guide rail buckle structure is installed on the shell and the guide rail block 200 does not move in the first direction OX, the two ends of the elastic rod 300 are against the first limit surface 110, and the remaining parts of the elastic rod 300 except the two ends are against the push portion 210. In this way, the elastic rod 300, the shell 100 and the guide rail block 200 can cooperate with each other, so that the guide rail block 200 will not move in the first direction OX. At this time, the contactor is clamped on the guide rail. Since the force received by the shaking or bumping of the contactor is not enough to deform the elastic rod 300, the guide rail buckle structure will not be displaced, thereby reducing the probability of the contactor falling off the guide rail due to the loose guide rail buckle structure, increasing the service life of the contactor, and reducing the probability of the contactor falling off the guide rail. The maintenance cost of the contactor in the later stage can also be reduced.
[0070] In addition, through the above-mentioned arrangement of the present application, when the guide rail block 200 moves in the first direction OX relative to the housing 100, the push portion can drive the remaining parts of the elastic rod except the two ends to move in the first direction, and the first limiting surface 110 can limit the two ends of the elastic rod 300, so that the elastic rod 300 is deformed and stores energy. After the elastic rod 300 is deformed, the guide rail block 200 continues to move in the first direction OX, and the locking portion 220 can be engaged with the locking surface 120. In this way, without applying external force, the guide rail block 200 can be stationary relative to the housing 100, realizing the automatic locking of the guide rail buckle structure and saving manpower.
[0071] After the guide rail snap-in structure is automatically locked to the shell, when the contactor needs to be installed on the guide rail, it is only necessary to apply external force to the guide rail block 200 to unlock the locking portion 220 and the locking surface 120. The elastic potential energy released by the elastic rod 300 can drive the guide rail block 200 to move toward the guide rail and clamp it to the guide rail, thereby realizing the installation of the contactor on the guide rail with high installation efficiency.
[0072] like Figure 3 As shown, there are two first limiting surfaces 110, which are located at opposite sides of the slide slot 150. The first limiting surface 110 includes a straight surface 111 and a bent surface 112 connected to each other, the bent surface 112 is closer to the slide slot 150 relative to the straight surface 111, and the bent surface 112 is farther from the push portion 210 relative to the straight surface 111.
[0073] By the above configuration, the first limiting surface 110 is configured as a straight surface 111 and a bent surface 112 connected to each other, so that the resistance of the first limiting surface 110 to the elastic rod 300 when the elastic rod 300 is deformed can be reduced, thereby reducing the difficulty of operating the guide rail block 200.
[0074] The locking portion 220 may be arranged in various forms, one of which is described below by way of example.
[0075] Fig.12 A schematic diagram of the structure of the guide rail block provided in an embodiment of the present application at one viewing angle. Fig.13 This is a schematic diagram of the structure of the guide rail block provided in the embodiment of the present application from another perspective. Fig. 9 as well as Figures 11 to 13 When the guide rail block 200 does not move in the first direction OX, the projection of the first projection in the first direction OX partially overlaps with the projection of the locking surface 120 in the first direction OX, and a first guide surface is provided on the side of the first projection away from the push portion 210 .
[0076] The first protrusion may be a protrusion structure provided on the guide rail block 200. The first protrusion may be integrally formed with the guide rail block 200, or the first protrusion may be separately formed with the guide rail block 200 and then assembled.
[0077] The first guiding slope may be a chamfer of the first protrusion disposed toward the first direction OX. The first guiding slope may reduce the resistance of the guide rail block 200 to the movement of the guide rail block 200 in the process of the guide rail block 200 moving toward the first direction OX.
[0078] Through the above arrangement, when the guide rail block 200 does not move in the first direction OX, the projection of the first protrusion in the first direction OX partially overlaps with the projection of the locking surface 120 in the first direction OX. In this way, after the first protrusion moves in the first direction OX, the locking surface 120 can limit the first protrusion. When the guide rail block 200 moves in the first direction OX, it is necessary to slightly lift the end of the guide rail block 200 away from the guide rail so that the first protrusion can be misaligned with the locking surface 120 to avoid the locking surface 120 from affecting the movement of the guide rail block 200. When the first protrusion is completely misaligned with the locking surface 120, the end of the guide rail block 200 away from the guide rail is lowered. At this time, the locking surface 120 can limit the first protrusion, thereby limiting the guide rail block 200.
[0079] like Figure 2 , Fig. 9 as well as Fig.11 As shown, the housing 100 further includes a second limiting surface 130, and the guide rail block 200 further includes a limiting portion 230. When the elastic rod 300 releases energy to drive the guide rail block 200 to move in the second direction OY to a preset position, the limiting portion 230 can abut against the second limiting surface 130 to limit the guide rail block 200 from continuing to move in the second direction OY, and the second direction OY is opposite to the first direction OX.
[0080] The limiting portion 230 may be a protruding structure provided on the guide rail block 200. The limiting portion 230 may be integrally formed with the guide rail block 200, or the limiting portion 230 may be separately formed with the guide rail block 200 and then assembled.
[0081] The preset position may be the position of the guide rail block 200 when the elastic rod 300 is in a normal state, and the preset position may also be the position of the guide rail block 200 when the contactor is installed on the guide rail.
[0082] The second direction OY can be the direction in which the guide rail block 200 moves toward the guide rail. The projection of the limiting portion 230 in the second direction OY partially overlaps with the projection of the second limiting surface 130 in the second direction OY. In this way, when the guide rail block 200 moves in the second direction OY, the second limiting surface 130 can limit the limiting portion 230.
[0083] Through the above-mentioned configuration, since the guide rail block 200 needs to be driven by the elastic rod 300 to move in the second direction OY during the process of the elastic rod 300 releasing energy, the elastic rod 300 often releases a large amount of energy in an instant during the process of releasing energy, which will cause the guide rail block 200 to move too far in the second direction OY. The configuration of the limiting portion 230 and the second limiting surface 130 can limit the guide rail block 200 when the guide rail block 200 moves in the second direction OY, thereby reducing the probability of the guide rail block 200 moving excessively and falling off the housing 100 driven by the elastic rod 300. In addition, the configuration of the second limiting surface 130 can also buffer the movement of the guide rail block 200 during the process of the guide rail block 200 moving in the second direction OY, thereby reducing the probability of the guide rail and the guide rail block 200 being damaged due to the direct impact of the guide rail block 200.
[0084] like Figure 2 , Figure 3 , Figure 5 , Fig.12 as well as Fig.13 As shown, the housing 100 is provided with two opposite limiting grooves 140, and the guide rail block 200 is provided with limiting blocks 240 on opposite sides of the arrangement direction of the two limiting grooves 140. The limiting blocks 240 are at least partially located in the limiting grooves 140 and can slide in the limiting grooves 140 along the first direction OX and the second direction OY.
[0085] The limiting groove 140 may be a groove structure provided on the housing 100, and the limiting groove 140 may be provided at the slide groove 150. The limiting groove 140 may be integrally formed with the housing 100, or may be provided on the housing 100 by carving or grooving after the housing 100 is formed, or a protruding structure may be provided on the groove wall of the slide groove 150 so that there is a gap between the protruding structure and the groove bottom of the slide groove 150, and the gap may be configured as the limiting groove 140.
[0086] The limit block 240 may be a protruding structure provided on the guide rail block 200. The limit block 240 may be integrally formed with the guide rail block 200, or the limit block 240 may be separately formed with the guide rail block 200 and then assembled. The limit block 240 may be in sliding contact with the groove wall of the limit groove 140, so that the limit groove 140 will not affect the movement of the guide rail block 200 during the process of limiting the limit block 240.
[0087] It should be noted that the present application does not limit the number of limit slots 140 and limit blocks 240, and the number of limit slots 140 can be two, four, or six, etc., and correspondingly, the number of limit blocks 240 can also be two, four, or six, etc. The present application only introduces the combination of two limit slots 140 and two limit blocks 240.
[0088] Through the above configuration, the limiting groove 140 is provided on the housing 100, and the limiting block 240 is provided on the guide rail block 200, so that the guide rail block 200 can be limited in the direction away from the bottom of the slide groove 150, thereby reducing the probability of the guide rail block 200 falling off the housing 100. The limiting block 240 is at least partially located in the limiting groove 140, and can slide in the limiting groove 140 along the first direction OX and the second direction OY. In this way, while the limiting groove 140 limits the limiting block 240, it will not affect the movement of the guide rail block 200 in the first direction OX and the second direction OY.
[0089] Since the volume of the contactor is generally small, the volume of the guide rail block 200 disposed on the housing 100 will be even smaller. Fig.13 As shown, the guide rail block 200 is provided with an operating portion 250, and the operating portion 250 is used to cooperate with a tool.
[0090] The operating portion 250 may be a protruding structure provided on the guide rail block 200, or a square hole or a circular hole provided on the guide rail block 200. The operating portion 250 may be provided on a side of the guide rail block 200 away from the guide rail.
[0091] Through the above configuration, setting the operating part 250 on the guide rail block 200 can make it easier for the operator to operate the guide rail block 200, and reduce the probability of the guide rail block 200 being difficult to operate due to the small size of the guide rail block 200, thereby affecting the installation of the contactor.
[0092] Similarly, since the guide rail block 200 is small in size, it is difficult to intuitively distinguish the state of the guide rail block 200 during operation. Fig.12 As shown, a mark is provided at a position of the guide rail block 200 near the locking portion 220 , and the mark is used to indicate the position of the guide rail buckle structure relative to the housing 100 , or the mark is used to indicate whether the contactor is installed on the guide rail.
[0093] The mark can be a line, groove or raised structure set on the guide rail block 200. When the mark coincides with the side wall of the shell 100, it can be determined that the guide rail block 200 is connected to the guide rail. When the mark can be clearly observed from the outside of the shell 100, it can be determined that the guide rail block 200 is in the energy storage state.
[0094] In summary, a mark is provided at the position of the guide rail block 200 near the locking portion 220, and the mark can be used to indicate the state of the guide rail block 200, so that the operator can clearly know whether the guide rail block 200 is correctly engaged with the guide rail. If the mark can be clearly observed outside the housing 100, it can be shown that the engagement between the guide rail block 200 and the guide rail is incomplete, so the contactor can be reinstalled on the guide rail until the contactor can be firmly installed on the guide rail. In this way, the probability of the contactor falling off the guide rail due to the loose guide rail buckle structure is reduced, and the service life of the contactor is increased.
[0095] Please continue to refer to Fig.13 As shown, the mark includes a first mark 260 and a second mark 270, and the first mark 260 is away from the push portion 210 relative to the second mark 270. When the guide rail buckle structure is installed on the housing 100 and the guide rail block 200 is not moved, or when the contactor is installed on the guide rail, the first mark 260 is exposed outside the housing 100. When the guide rail block 200 moves relative to the housing 100 in the first direction OX so that the locking portion 220 is engaged with the locking surface 120, the first mark 260 and the second mark 270 are both exposed outside the housing 100.
[0096] The first mark and the second mark can be represented by color or shape, etc., the first mark and the second mark are different from each other, and there can be a clear dividing line between the first mark and the second mark. For example, the first mark can be red and the second mark can be green, or the first mark can be a square protrusion and the second mark can be a round protrusion.
[0097] Through the above settings, the marks are set as the first mark and the second mark respectively, so that the status display of the guide rail block 200 can be made more obvious, and the observation of the operator can be made more convenient. When only the first mark is exposed outside the shell 100, it can be determined that the guide rail block 200 is connected to the guide rail. If the first mark and the second mark are both exposed outside the shell 100, it can be determined that the guide rail block 200 is in the energy storage state. If the first mark and part of the second mark are exposed outside the shell 100, it can be determined that the guide rail block 200 is not completely connected to the guide rail. At this time, the contactor can be removed from the guide rail and reinstalled.
