[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 7The utility model provides a technical solution: a contactor base, including a contactor base 1, a fixed card block 2 fixedly connected to the contactor base 1, and a movable card block 3 movably arranged on the contactor base 1. The fixed card block 2 cooperates with the movable card block 3 to fix the contactor base 1 on the electrical rail. The inner side of the movable card block 3 is fixedly connected to a round rod 6, and the outer side of the round rod 6 is sleeved with a first spring 7. The first spring 7 is used to provide a holding force to the movable card block 3 and can also make the movable card block 3 automatically reset. A support plate 21 is provided on the contactor base 1. The support plate 21 cooperates with the movable card block 3 to compress the first spring 7. The support plate 21 is penetrated A circular hole 20 is provided, which is used to avoid the round rod 6 to prevent the round rod 6 from being blocked by the support plate 21, resulting in the movable card block 3 being unable to move normally. The round rod 6 is slidably connected to the circular hole 20, and the movable card block 3 is respectively penetrated by an empty groove 8 and a square groove 15. The empty groove 8 is connected to the square groove 15. A cross bar 9 is slidably installed inside the square groove 15. A locking block 10 is provided at one end of the cross bar 9. A locking groove 11 that cooperates with the locking block 10 is provided on the contactor base 1. The locking groove 11 cooperates with the locking block 10 to lock the movable card block 3 to prevent the movable card block 3 from moving up and down in a vibration environment, resulting in the contactor base 1 being not firmly installed. A through groove is provided on the cross bar 9 12, the inner side wall of the through slot 12 is provided with an inclined portion 24, and a T-shaped slot 25 is provided on the inclined portion 24. The movable card block 3 is slidably connected with a vertical rod 17, and one end of the vertical rod 17 passes through the through slot 12 and extends to the top of the cross bar 9. A tilted block 23 is provided on one side of the vertical rod 17. The inclined surface of the tilted block 23 is in close contact with one side of the inclined portion 24. When the vertical rod 17 moves downward, the vertical rod 17 will drive the tilted block 23 to move downward. The tilted block 23 squeezes the inclined portion 24 to make the cross bar 9 move to the right. The cross bar 9 drives the locking block 10 to move to the right, and the locking block 10 disengages from the lock slot 11, thereby releasing the lock of the movable card block 3. The tilted block 23 is provided with a T-shaped block slidably connected to the T-shaped slot 25 22. When the vertical rod 17 moves upward, the vertical rod 17 moves the T-shaped block 22 upward through the oblique block 23, the T-shaped block 22 moves the cross bar 9 to the left, and the cross bar 9 moves the locking block 10 to the left. The locking block 10 enters the locking groove 11 to lock the movable card block 3. A pressure plate 14 is provided on the outside of the vertical rod 17 and below the cross bar 9. The pressure plate 14 facilitates the vertical rod 17 to compress the second spring 16. The outside of the vertical rod 17 is sleeved with a second spring 16. The second spring 16 is used to apply an upward thrust to the pressure plate 14, so that the vertical rod 17 can be automatically reset after being pulled, and it can ensure that the locking block 10 is always in the locking groove 11, thereby locking the movable card block 3.

[0021] The vertical rod 17 is slidably connected to the through slot 12 .

[0022] A limit plate 13 is provided at the top of the vertical rod 17, which is used to limit the vertical rod 17 to prevent the vertical rod 17 from being pulled too far when moving downward, resulting in the T-shaped block 22 and the T-shaped slot 25 being completely separated. A grip plate 18 is provided at the bottom of the vertical rod 17, which makes it convenient for the user to pull the vertical rod 17.

[0023] The end of the locking block 10 away from the cross bar 9 is provided with a chamfer 26 , and the chamfer 26 makes it easier for the locking block 10 to be aligned with the locking slot 11 and inserted.

[0024] A protrusion 5 is provided on one side of the contactor base 1, and a slide groove 19 is formed between the protrusion 5 and the contactor base 1. Both sides of the movable card block 3 are integrally formed with an L-shaped block 4 that is slidably connected to the slide groove 19. The long side of the L-shaped block 4 can slide in the slide groove 19, so that the movable card block 3 can slide on the contactor base 1, and the short side of the L-shaped block 4 will be blocked by the protrusion 5, which has a limiting effect on the movable card block 3, preventing the movable card block 3 from moving upward without restriction under the action of the first spring 7, causing the movable card block 3 to separate from the contactor base 1.

[0025] Specifically, when installing it on the electrical rail, first clamp the fixed card block 2 on one side of the electrical rail, pull the grip plate 18 downward, and the grip plate 18 makes the vertical rod 17 move downward. At this time, the locking block 10 is in the locking groove 11, and the movable card block 3 cannot move. The vertical rod 17 makes the pressure plate 14, the limit plate 13 and the inclined block 23 move downward. The pressure plate 14 moves downward to compress the second spring 16, and the inclined block 23 squeezes the inclined portion 24 to make the cross bar 9 move to the right. The cross bar 9 drives the locking block 10 to move to the right, and the locking block 10 disengages from the locking groove 11, thereby releasing the lock of the movable card block 3. At this time, the bottom of the limit plate 13 contacts the top of the cross bar 9, and the grip plate 18 is continued to be pulled downward to make the limit plate 13 move downward. The limit plate 13 makes the movable card block 3 move downward through the cross bar 9, and the movable card block 3 compresses the first spring 7. At this time, the movable card block 3 The movable card block 3 no longer blocks the electrical guide rail, so that the contactor base 1 is close to the electrical guide rail, and then the grip plate 18 is released, the first spring 7 bounces back and resets, causing the movable card block 3 to reset upward, and the movable card block 3 is also stuck on one side of the electrical guide rail, thereby fixing the contactor base 1 on the electrical guide rail. As the movable card block 3 resets upward, the locking block 10 will be aligned with the locking groove 11. After alignment, the second spring 16 bounces back and resets to cause the pressure plate 14 to move upward, and the pressure plate 14 causes the vertical rod 17 to move upward. The vertical rod 17 passes through the oblique block 23 to cause the T-shaped block 22 to move upward, and the T-shaped block 22 causes the cross bar 9 to move to the left. The cross bar 9 causes the locking block 10 to move to the left, and the locking block 10 is stuck in the locking groove 11, locking the movable card block 3 to prevent the movable card block 3 from moving up and down due to vibration, which causes the contactor base 1 to be installed loosely.
