Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] In this technical solution, a protective device for a platform escalator includes a main baffle 1 and a secondary baffle 2. The main baffle 1 is installed on the side wall of the entrance of the external platform escalator, and the secondary baffle 2 is rotatably installed on the side wall of the main baffle 1.

[0023] The auxiliary baffle 2 includes an inclined plate 21, a connecting hole 22, a threaded hole 23, a bolt 24, and a pressure plate 25. The side wall of the inclined plate 21 has a connecting hole 22. The side wall of the main baffle 1 is equipped with a protruding post 3, which can be inserted into the connecting hole 22. The side wall of the inclined plate 21 has a threaded hole 23, and a bolt 24 is screwed into the threaded hole 23. The outside of the bolt 24 is sleeved with a pressure plate 25. The side wall of the pressure plate 25 has a positioning hole 4. The side wall of the protruding post 3 is equipped with a positioning gear 5. The inner side wall of the positioning hole 4 has a tooth groove 6, which can mesh with the tooth groove 6.

[0024] In this technical solution, the secondary baffle 2 is installed on the main baffle 1 through the cooperation between the protruding post 3 and the connecting hole 22, so that the angle of the secondary baffle 2 can be adjusted, thereby making the device suitable for escalators with different slopes and ensuring the protective effect of the device on the escalator.

[0025] After adjusting the angle of the sub-baffle 2, the pressure plate 25 needs to be pressed onto the positioning gear 5 at the end of the protrusion 3 by rotating the bolt 24, so that the positioning gear 5 is inserted into the positioning hole 4 and meshes with its tooth groove 6, thereby fixing the angle of the sub-baffle 2.

[0026] In some technical solutions, the side walls of the main baffle 1 and the inclined plate 21 are both equipped with insert rods 7. The insert rods 7 can be inserted into the connection holes installed on the side walls of the external platform escalator. The insert rods 7 are equipped with positioning mechanisms 8.

[0027] In this technical solution, the device can be quickly installed on the outside of the escalator by the cooperation between the insertion rod 7 and the connection hole on the side wall of the external escalator, thus improving the installation efficiency of the device.

[0028] In some technical solutions, the positioning mechanism 8 includes a slide groove 81, a slider 82, a through groove 83, a positioning pin 84, and a spring 85. The side wall of the insertion rod 7 is provided with a slide groove 81. One end of the spring 85 is installed on the inner side wall of the slide groove 81, and the other end of the spring 85 is installed with a slider 82. The side wall of the insertion rod 7 located in the external connection hole is provided with a through groove 83. The positioning pin 84 is slidably installed in the through groove 83. The positioning pin 84 can fit against the side wall of the slider 82 and can be engaged in the limiting groove installed on the inner wall of the external connection hole.

[0029] In this technical solution, the stability of the installation of the main baffle 1 and the auxiliary baffle 2 can be further improved by setting the positioning mechanism 8. When the insertion rod 7 is inserted into the connection hole, its spring 85 will provide a pushing force to the slider 82, so that it pushes the positioning pins 84 on both sides outward, thereby locking them into the limiting groove on the inner wall of the connection hole.

[0030] In some technical solutions, the sidewalls of both the slider 82 and the locating pin 84 are inclined.

[0031] In this technical solution, the sidewalls of slider 82 and positioning pin 84 are inclined, which can avoid interference between slider 82 and positioning pin 84.

[0032] In some technical solutions, one end of a pull rope 9 is installed on the side wall of the slider 82, and the other end of the pull rope 9 passes through the side wall of the insertion rod 7 and is fitted with a pull ring 10.

[0033] In this technical solution, the slider 82 can be pulled by the pull rope 9, thereby releasing it from pushing the positioning pin 84, so that the positioning pin 84 retracts into the through groove 83, allowing the device to be quickly removed from the escalator for easy maintenance.

[0034] In some technical solutions, one end of a rubber pad 11 is attached to the upper wall of the inclined plate 21, and the other end of the rubber pad 11 is attached to the upper wall of the main baffle 1.

[0035] In this technical solution, the rubber pad 11 can cover the gap between the main baffle 1 and the secondary baffle 2 to prevent fingers from being pinched.

[0036] Working principle: When installing this device, first install the main baffle 1 on the escalator through the fit between the insert rod 7 and the connecting hole on the side wall of the escalator. Then, adjust the angle of the auxiliary baffle 2 according to the angle of the escalator. After adjusting the angle of the auxiliary baffle 2, rotate the bolt 24 to press the pressure plate 25 onto the positioning gear 5 at the end of the protrusion 3, so that the positioning gear 5 is inserted into the positioning hole 4 and meshes with its tooth groove 6, thereby fixing the angle of the auxiliary baffle 2. After fixing, it can be installed on the escalator through the insert rod 7 on the auxiliary baffle 2.

[0037] When the insert rod 7 is inserted into the connecting hole, its spring 85 will provide a pushing force to the slider 82, causing it to push the positioning pins 84 on both sides outward, thereby locking them into the limiting groove on the inner wall of the connecting hole, further improving the stability of the installation of the main baffle 1 and the auxiliary baffle 2.
