[0021] 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.

[0022] Example: Reference Figure 1-5 The Z-type hoist backstop device shown includes a hoist body 1, a ratchet 2, and a pawl mechanism 3. The rotating shaft of the hoist body 1 is coaxially arranged with the ratchet 2, and a pawl mechanism 3 is provided on one side of the ratchet 2 to cooperate with the ratchet 2. In order to protect and maintain the ratchet 2, a protective shell is fitted on the ratchet 2. The protective shell is provided with an oil inlet 50. When in use, lubricating oil is injected into the inside of the protective shell through the oil inlet 50. When the hoist body 1 is started, the rotating shaft drives the ratchet 2 to rotate inside the protective shell, automatically adhering to the lubricating oil for lubrication.

[0023] To facilitate the cooperation between the pawl mechanism 3 and the ratchet 2, a notch 51 is provided on the protective housing for the pawl mechanism 3 to move. In order to prevent the lubricant from being thrown out from the notch 51 when the ratchet 2 rotates, a set of splash guards 6 are hinged to the top surface of the protective housing. The splash guards 6 cooperate with the pawl mechanism 3 to prevent lubricant from splashing.

[0024] As one embodiment of this invention, the protective shell: the bottom shell 4 is detachably mounted on the hoist body 1, and the top shell 5 is assembled by engaging with the insert 40 on the top surface of the bottom shell 4 through a slot 52 on the bottom surface, thus protecting the ratchet 2. A groove is provided on the top surface of the top shell 5, and a notch 51 is provided on one side of the groove (e.g., ...). Figure 4 As shown), a set of splash guards 6 are hinged in the groove, and an oil inlet 50 is provided in the groove. After the protective shell is assembled, oil is injected from the oil inlet 50.

[0025] As one embodiment of this invention, the splash guard 6 is an arc-shaped plate, and a U-shaped protective member 61 is provided on the outer wall of the splash guard 6. In the non-use state, the protective member 61 covers the oil inlet 50, and the U-shaped protective member 61 avoids direct contact with the oil inlet 50 and causes damage. A set of drainage blocks 60 is provided on the inner wall of the splash guard 6. The bottom surface of the drainage block 60 is arc-shaped. When the splash guard 6 is rotated 180° for use, the straight surface of the drainage block 60 abuts against the notch 51 to prevent the splash guard 6 from directly contacting the pawl mechanism 3 and causing wear. In addition, the arc surface on the drainage block 60 can guide the splashed lubricating oil back into the protective shell.

[0026] As one embodiment of this invention, a slide rail 100 is provided on the outer wall of the hoist body 1. There are two sets of slide rails 100, and the cross-sectional shape of the slide rail 100 is T-shaped. A slider 41 is provided on the outer wall of the bottom shell 4. The slider 41 is adapted to the slide rail 100. In use, by pushing the bottom shell 4 upward, the slider 41 slides in the slide rail 100 and cooperates with the top shell 5 to wrap the ratchet 2. In order to fix the position of the bottom shell 4, a support fixing member 7 is provided on the bottom surface of the bottom shell 4. The support fixing member 7 is connected to the hoist body 1 by bolts to achieve fixed installation.

[0027] The working principle of this utility model is as follows: After the utility model is installed, when in use, the pawl mechanism 3 is inserted into the large notch 51 of the top shell 5, so that the pawl and the ratchet 2 cooperate to achieve the backstop effect on the hoist body 1. Then, the anti-splash plate 6 in the groove of the top shell 5 is flipped. After the anti-splash plate 6 is flipped 180 degrees, the maximum flip angle is limited by the guide block 60. Then, oil is injected into the inside of the protective shell through the oil inlet 50 in the groove. The lubricating oil accumulates at the bottom of the bottom shell 4 and automatically adheres when the ratchet 2 rotates. The anti-splash plate 6 prevents the lubricating oil from splashing out when the ratchet 2 is rotating. The guide block 60 guides the lubricating oil back into the protective shell.

[0028] When replacement and maintenance are required, remove the top shell 5 to separate the slot 52 from the insertion post 40. Then remove the bolts on the support fixing part 7 to disconnect the connection between the support fixing part 7 and the hoist body 1. With the cooperation of the slide rail 100 and the slider 41, the bottom shell 4 slides down and is then removed. The lubricating oil inside the bottom shell 4 is then removed and replaced.
