DETAILED DESCRIPTION

[0018] The embodiment of the present application discloses an anti-pollution and anti-collision device for a hanging basket travel switch, which cushions the collision of the contact 40 through the two first springs 65 on the top of the shell 10 to prevent the contact 40 from being damaged during the collision. The elastic force of the four second springs 73 on the front of the travel switch housing 30 is used to cushion the impact force on the travel switch housing 30, thereby increasing the service life of the travel switch.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 The present embodiment provides a pollution prevention and collision prevention device for a hanging basket travel switch, including a shell 10, a travel switch shell 30 is arranged inside the shell 10, a contact 40 is arranged on the top of the travel switch shell 30, the contact 40 extends out of the shell 10, a top is arranged on the top of the shell 10, the contact 40 contacts the baffle, and top buffer components 60 are arranged on both sides of the top of the shell 10. The front of the travel switch shell 30 and the four corners of the inner wall of the shell 10 are inclined surfaces, and a front buffer component 70 is arranged between two corresponding inclined surfaces. The four front buffer components 70 include a second fixing sleeve 71, a second telescopic rod 72, a second spring 73, and a second fixing plate 74. The second fixing sleeve 71 is arranged at the corner of the travel switch shell 30, and the second telescopic rod 72 is inserted and connected The second fixing plate 74 is connected to the top of the second fixing sleeve 71, and is arranged at the top of the second telescopic rod 72. The second fixing plate 74 is fixedly connected to the inner wall of the shell 10. The second spring 73 is sleeved on the outer side of the second telescopic rod 72. The two ends of the second spring 73 are respectively fixedly connected to the second fixing sleeve 71 and the second fixing plate 74. The hanging basket and the shell 10 are driven up by the lifting motor. The collision between the contact 40 and the top baffle causes the contact 40 to retract into the travel switch housing 30, and then the lifting motor is turned off, and the hanging basket stops. Through the contraction of the second telescopic rod 72 and the elastic force of the second spring 73, the impact force on the travel switch housing 30 is buffered by the second springs 73 at the four corners, so as to prevent the travel switch housing 30 from being damaged by external force, thereby improving the service life of the travel switch.

[0021] Please refer to Figure 1-Figure 4A through slot 20 is provided at the top of the housing 10, a rubber sleeve 50 is provided on the outer side of the contact 40, the rubber sleeve 50 is slidably connected to the inside of the through slot 20, and the size of the rubber sleeve 50 matches the through slot 20, the two top buffer components 60 include a connecting plate 61, a first fixed sleeve 62, a movable slot 63, a first telescopic rod 64, a first spring 65, and a first fixed plate 66, the connecting plate 61 is arranged on one side of the top of the housing 10, the first fixed sleeve 62 is fixedly arranged on the top of the connecting plate 61, the movable slot 63 is opened on the top of the first fixed sleeve 62, the first telescopic rod 64 is slidably connected to the inside of the movable slot 63, the first spring 65 is arranged in the inside of the movable slot 63, the two ends of the first spring 65 are respectively fixedly connected to the bottom of the movable slot 63 and the first telescopic rod 64, the first fixed plate 66 6 is arranged at the top of the first telescopic rod 64, and the horizontal height of the first fixing plate 66 is higher than the horizontal height of the top of the contact 40. The rubber sleeve 50 on the outside of the contact 40 plays a buffering role when the contact 40 is hit, and can also fill the through groove 20 to play a sealing role to prevent various building material particles from falling into the gap between the contact 40 and the travel switch housing 30, thereby realizing the protection of the travel switch housing 30 and avoiding the problem that the contact 40 is stuck and cannot work due to the building material particles. The first fixing plate 66 first contacts with the top baffle, and cooperates with the elastic force of the first spring 65 to reduce the impact force when the contact 40 is hit, avoids directly hitting the travel switch housing 30, and causes the travel switch to fail, thereby improving the service life of the travel switch.

[0022] This application can explain its functional principle through the following operation methods:

[0023] When in use, the lifting motor of the hanging basket is started to drive the hanging basket and the shell 10 to move upward. When they move to a certain height, the first fixing plates 66 on both sides of the top of the shell 10 first contact the baffle, so that the first fixing plates 66 drive the first telescopic rod 64 to retract into the movable groove 63, so that the first spring 65 inside the movable groove 63 is compressed, and the elastic force of the first spring 65 and the rubber sleeve 50 outside the contact 40 reduce the impact force received by the contact 40 when it collides with the baffle. The upward movement of the hanging basket and the shell 10 causes the contact 40 to retract into the shell 10 and the interior of the travel switch housing 30, and the lifting motor is turned off, so that the hanging basket and the travel switch stop moving upward. The collision of the first fixing plate 66 with the baffle causes the shell 10 to be subjected to an impact force, thereby causing the shell 1 0, the four second telescopic rods 72 inside are retracted into the second fixed sleeve 71, and the second springs 73 outside the second telescopic rods 72 are compressed. The elastic force of the second springs 73 can reduce the impact force on the travel switch housing 30, prevent the travel switch housing 30 from being damaged by external impact, and prevent the travel switch housing 30 from being damaged by external collision during daily use. The rubber sleeve 50 outside the contact 40 can seal the housing 10 and the travel switch housing 30, play a sealing role, and prevent various external building material particles from falling into the gap between the contact 40 and the travel switch housing 30, thereby realizing the protection of the travel switch housing 30 and avoiding the problem that the contact 40 is stuck and cannot work due to the building material particles.
