The first rod sleeve 31 and the second rod sleeve 41 form a circular rod sleeve and are installed on the outside of the oil cylinder piston rod 2. A fixing structure is provided between both sides of the first protective sub-cover body 3 and the second protective sub-cover body 4. Through the split design of the protective cover composed of the first protective sub-cover body 3 and the second protective sub-cover body 4 in the present utility model, the protective cover can be added on the basis of the existing installed oil cylinder without disassembling and removing the oil cylinder, improving the installation convenience. Through the setting of the first rod sleeve 31 and the second rod sleeve 41, it is convenient to connect and fix the first protective sub-cover body 3 and the second protective sub-cover body 4 to the oil cylinder piston rod 2. Through the setting of the fixing structure, it is convenient to assemble and fix the first protective sub-cover body 3 and the second protective sub-cover body 4, and this structure also facilitates the quick disassembly and replacement of the first protective sub-cover body 3 and the second protective sub-cover body 4. The structure is simple and the installation efficiency is improved.

[0024] In this embodiment, as Figure 2 and Figure 3 shown, a positioning block 311 is fixedly connected to the inner wall of the first rod sleeve 31, and a positioning groove 21 for the positioning block 311 to be inserted into is provided on the outer wall of the oil cylinder piston rod 2. When installing the protective cover, first install the first protective sub-cover body 3 on the outside of the oil cylinder. By aligning and inserting the positioning block 311 into the positioning groove 21, it is used to initially position the position of the first protective sub-cover body 3, facilitating the alignment of the counterbore and the first fixing hole, and thus facilitating the positioning installation of the first protective sub-cover body 3.

[0025] In this embodiment, as Figure 2 and Figure 3As shown, a groove is provided on the outer side of the first protective sub-housing 3 close to the second protective sub-housing 4, and a rib is provided on one side of the second protective sub-housing 4 close to the first protective sub-housing 3 for fitting and snapping into the groove. After the first protective sub-housing 3 is installed, the second protective sub-housing 4 is installed. The rib of the second protective sub-housing 4 is aligned and snapped into the groove of the first protective sub-housing 3 for positioning and installing the second protective sub-housing 4, improving the installation efficiency. In other embodiments, a sealing ring is provided at the connection between the first protective sub-housing 3 and the second protective sub-housing 4 to improve the sealing effect.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 shown, the fixing structure includes a first connecting plate 32 fixedly connected along the length direction of both sides of the outer wall of the first protective sub-housing 3 and a second connecting plate 42 fixedly connected along the length direction of both sides of the outer wall of the second protective sub-housing 4. A pressing block 33 is fixedly connected to one side of the first connecting plate 32 close to the second connecting plate 42. A plurality of pressing blocks 33 are arranged at equal intervals along the length direction of the first connecting plate 32. A clamping groove 331 is provided on the pressing block 33, and a through groove 421 for the pressing block 33 to pass through is provided on the second connecting plate 42. The fixing structure further includes a pushing rod 5 snapped into the through groove 421. A plurality of second fixing holes are provided on the pushing rod 5, and third fixing holes corresponding to the positions of the second fixing holes are provided on the outer wall of the second protective sub-housing 4. The pushing rod 5 and the second protective sub-housing 4 are fixedly connected by a second connecting bolt 8 passing through the second fixing hole and the third fixing hole. After the first protective sub-housing 3 and the second protective sub-housing 4 are installed in place, the pressing block 33 on the first connecting plate 32 passes through the through groove 421 on the second connecting plate 42, and then the pushing rod 5 is placed in the clamping grooves 331 of all the pressing blocks 33 on one side. The pushing rod 5 is fixed to the second protective sub-housing 4 by the second connecting bolt 8 for connecting and fixing the first protective sub-housing 3 and the second protective sub-housing 4.

[0027] In this embodiment, as Figure 4 shown, the cross-section of the pushing rod 5 is a right trapezoidal structure. An inclined opening for fitting and sliding is provided on one side of the clamping groove 331 that fits with the inclined surface of the pushing rod 5. Through the cooperation of the inclined surface of the pushing rod 5 and the inclined opening of the clamping groove 331, when the pushing rod 5 enters deeper into the clamping groove 331, the first protective sub-housing 3 and the second protective sub-housing 4 can be gradually tightened, making the first protective sub-housing 3 and the second protective sub-housing 4 fit more closely and improving the connection and installation effect of the first protective sub-housing 3 and the second protective sub-housing 4.

[0028] In this embodiment, as Figure 4As shown, a chute 422 is formed on the outer wall of the second connecting plate 42. One side of the pushing rod 5 is fixedly connected with a slider 51 that cooperates with the chute 422 for sliding.

The inner rings of the anti-slag rings 6 are slidably attached to the outer surface of the cylinder barrel 1 of the oil cylinder. The anti-slag rings 6 are used to remove the slag on the outer surface of the cylinder barrel 1 of the oil cylinder, preventing it from entering the protective housing and hindering its movement.

[0030] Working principle: During use, the positioning block 311 is aligned and snapped into the positioning groove 21 for initially positioning the first protective sub-housing 3. The convex strip of the second protective sub-housing 4 is aligned and snapped into the groove of the first protective sub-housing 3 for positioning and installing the second protective sub-housing 4. Then, the first connecting bolt 7 passes through the counterbore and the first fixing hole to connect and fix the first protective sub-housing 3 and the second protective sub-housing 4 to the oil cylinder piston rod 2. At this time, the pressing block 33 on the first connecting plate 32 passes through the through groove 421 on the second connecting plate 42, and then the pushing rod 5 is snapped into the snap-in groove 331 of the pressing block 33 on one side. The pushing rod 5 is fixed to the second protective sub-housing 4 by the second connecting bolt 8 for connecting and fixing the first protective sub-housing 3 and the second protective sub-housing 4. The split design of the protective housing of the present utility model, which consists of the first protective sub-housing 3 and the second protective sub-housing 4, enables the protective housing to be installed on the existing installed oil cylinder without disassembling the oil cylinder, improving the installation convenience. Moreover, the first protective sub-housing 3 and the second protective sub-housing 4 can be quickly disassembled and replaced, with a simple structure and high installation efficiency.
