The opening at the top is convenient for dripping lubricating oil and coolant, but it is easy to accumulate sludge. The opening downward is difficult to drip lubricating oil and coolant, and the added lubricating oil is easy to drip and cause waste, but the accumulated sludge can be discharged.

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Reference Figures 1 to 4 The embodiment of the present invention is an open wear-resistant sleeve with an anti-falling mechanism, which includes a fixing seat 1, the upper end of the fixing seat 1 is fixedly connected to the lower fixing end 2, the upper end of the lower fixing end 2 is provided with a semicircular groove, two fixing holes 4 are provided at each end of the upper surface of the lower fixing end 2, the upper end of the lower fixing end 2 is movably connected to the upper fixing end 3, the upper fixing end 3 and the fixing holes 4 on the surface of the lower fixing end 2 are also provided with the same number of fixing holes 4, the fixing holes 4 are threadedly connected with screws 5, the lower fixing end 2 and the upper fixing end 3 form a cylindrical through hole, the right end of the upper fixing end 3 is provided with an anti-falling device 6, and the right side of the fixing seat 1 is provided with a rotating device 11. The upper fixing end 3 and the lower fixing end 2 are fixed together by the screws 5, and a cylindrical space is formed inside the upper fixing end 3 and the lower fixing end 2, in which a sleeve can be placed. A bearing is placed inside the sleeve, and the sleeve is fixed to the outer surface of the bearing by the anti-falling device 6. The sleeve can be rotated by the rotating device 11, which facilitates the control of the direction of the opening of the open sleeve 601 so as to work better.

[0023] The anti-drop device 6 includes an open sleeve 601, a sleeve left end 602, a sliding end 603, a sleeve right end 604, a screw 605, and a positioning rod 606. The open sleeve 601 is rotatably connected to the cylindrical through hole formed by the lower fixed end 2 and the upper fixed end 3. The rotatable connection of the open sleeve 601 within the cylindrical through hole allows the shaft to contact only the sleeve, reducing interference from external factors and the possibility of damage.

[0024] The left end 602 of the sleeve is fixedly connected to the left end surface of the open sleeve 601, and the right end 604 of the sleeve is fixedly connected to the right end surface of the open sleeve 601. The central axis directions of the open sleeve 601 and the left and right ends 602 and 604 of the sleeve coincide with each other. The left end 602 of the sleeve is fixed to the left end of the open sleeve 601, so that the sleeve will not slide to the left, achieving a position limiting effect.

[0025] The sliding end 603 is horizontally slidably connected to the side surface of the open shaft sleeve 601. The right end of the positioning rod 606 is fixedly connected to the inside of the right end 604 of the shaft sleeve. The left end of the positioning rod 606 is slidably connected to the inside of the sliding end 603. The left end of the screw rod 605 is threadedly connected to the inside of the sliding end 603. The sliding end 603 slides horizontally on the side surface of the open shaft sleeve 601, which can fix the movement of the shaft sleeve on the right side to achieve a limit function. In conjunction with the screw rod 605 and the positioning rod 606, the sliding end 603 can be controlled to limit the movement of the open shaft sleeve 601 and prevent it from detaching.

[0026] The rotating device 11 includes a support plate 1101, a worm 1102, a worm wheel 1103, and a motor 1104. The support plate 1101 is fixedly connected to the right side of the fixed base 1, and the worm 1102 is horizontally connected to the side surface of the support plate 1101. The worm 1102 meshes with the worm wheel 1103 to control the rotation of the worm wheel 1103. The worm wheel 1103 rotates coaxially with the right end 604 of the sleeve, driving the right end 604 of the sleeve to rotate. The right end 604 of the sleeve is fixedly connected to the open sleeve 601, thereby controlling the rotation of the open sleeve 601 and facilitating the adjustment of the opening direction of the open sleeve 601 to adapt to different working conditions.

[0027] Motor 1104 is fixedly connected to the surface of support plate 1101. The output end of motor 1104 is fixedly connected to worm 1102. Worm gear 1103 is fixedly connected to the side surface of right end 604 of sleeve. Worm 1102 and worm gear 1103 are threadedly connected. When motor 1104 is connected to an external power source and then started, worm 1102 can be controlled to rotate. Worm 1102 and worm gear 1103 are engaged, which can drive worm gear 1103 to rotate. Worm gear 1103 rotates coaxially with right end 604 of sleeve, which can drive right end 604 of sleeve to rotate. Right end 604 of sleeve is fixedly connected to open sleeve 601, thereby controlling the rotation of open sleeve 601.

[0028] A vertical oil injection pipe 7 is fixedly connected to the upper surface of the upper fixed end 3. The oil injection pipe 7 extends through the upper surface of the upper fixed end 3 and is rotatably connected to the upper surface of the oil injection pipe 7. A slot 9 is formed at the lower end of the lower fixed end 2, and a rectangular through-hole is formed at the lower end of the slot 9. A collection box 10 is disposed within the rectangular through-hole. Rotating the cover 8 opens the oil injection pipe 7, allowing lubricating oil to be injected into the sleeve, thereby reducing friction and protecting the bearing. When the opening of the open sleeve 601 is downward, excess lubricating oil and accumulated sludge inside the sleeve can fall through the slot 9 into the collection box 10 below for unified disposal.

[0029] Working principle: After installing the open shaft sleeve 601, rotate the screw 605 to control the sliding end 603 to slide left and right, so that the sliding end 603 is close to the right end of the open shaft sleeve 601, which can limit the open shaft sleeve 601 and prevent it from falling off. Then, when it is necessary to add lubricating oil or coolant, the motor 1104 can be started to control the rotation of the worm 1102. The worm 1102 is engaged with the worm wheel 1103, which can drive the worm wheel 1103 to rotate. The worm wheel 1103 rotates coaxially with the right end 604 of the shaft sleeve, which can drive the right end 604 of the shaft sleeve to rotate. 04 rotates, the right end 604 of the sleeve is fixedly connected to the open sleeve 601, thereby controlling the rotation of the open sleeve 601. When the opening of the open sleeve 601 is upward, rotate the cover 8 to open the oil filling pipe 7 to add lubricating oil, etc., and then cover the cover 8 to prevent dust from falling. When it is necessary to clean the sludge and excess lubricating oil accumulated inside the open sleeve 601, repeat the above operation to make the opening of the open sleeve 601 downward and align with the slot 9. As the shaft rotates, the sludge and lubricating oil will fall into the collection box 10 below through the slot 9, which is convenient for unified treatment.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
