The outer sides of the first protective shell 300 and the second protective shell 301 are both provided with a heat dissipation mechanism for convenient heat dissipation and cooling. The bottom of the fixed seat 101 is provided with a supporting mechanism that plays a supporting and anti-collision role.

[0030] In one embodiment, Figure 1 As shown, an oil inlet 102 is formed on the side wall of the fixing seat 101 .

[0031] In one embodiment, Figure 4-Figure 7As shown, the clamping mechanism includes a first mounting block 302, a second mounting block 303, a mounting groove 304, a locking block 305, a moving rod 306, a moving groove 307, a spring 308, a handle 309, a clamping block 310, and a clamping groove 311. The first protective shell 300 has a first mounting block 302 fixedly disposed symmetrically on the side wall thereof. The first mounting block 302 has a mounting groove 304 disposed on the side wall thereof. A moving groove 307 is disposed on the side wall of the mounting groove 304. A moving rod 306 is movably disposed in the moving groove 307. A locking block 305 is fixedly disposed on the end of the moving rod 306. A spring 308 is sleeved on the shaft of the moving rod 306. One end of the spring 308 is fixedly connected to the side wall of the moving groove 307. The other end of the spring 308 is fixedly connected to the bottom of the locking block 305. The other end of the moving rod 306 extends to the first mounting block 302. The second protective shell 301 is symmetrically fixed with a second mounting block 303 on its side wall, and a clamping block 310 matched with the mounting groove 304 is fixedly connected to the side wall of the second mounting block 303. A clamping groove 311 matched with the locking block 305 is provided on the side wall of the clamping block 310. The clamping block 310 is clamped into the mounting groove 304, and the locking block 305 is clamped into the clamping groove 311 by the spring 308, so as to facilitate the clamping installation of the first protective shell 300 and the second protective shell 301. The operation is simple, the installation is fast, and time is saved. When the cylinder body 203 needs to be inspected, the handle 309 is used to drive the moving rod 306 to move, so that the locking block 305 is away from the clamping block 310, and then the clamping block 310 is pulled out to release the clamping locking state, so as to facilitate the timely inspection of the cylinder body 203 and improve work efficiency.

[0032] In one embodiment, Figure 5-Figure 6 As shown, the side wall of the handle 309 is provided with a plurality of anti-skid grooves to play an anti-skid role, so that the user can better move the moving rod 306 through the handle 309 .

A connecting rod 105 is provided between the top of the fixing seat 101 and the bottom of the top plate 106. A plurality of heat sinks 104 are provided on the connecting rod 105. The side walls of the heat sink 104 abut against the outer sides of the first protective shell 300 and the second protective shell 301. When the oil cylinder generates more heat during operation, the heat sink 104 can efficiently absorb and dissipate the heat transferred from the first protective shell 300 and the second protective shell 301, thereby greatly improving the heat dissipation performance of the oil cylinder, keeping the temperature in the oil cylinder within a suitable temperature range, avoiding the situation in which the high temperature in the cylinder accelerates the aging of the hydraulic oil and the deterioration of the oil seal, improving the performance of the oil cylinder, and extending the service life of the oil cylinder.

[0034] In one embodiment, Figure 1-Figure 3 As shown, the supporting mechanism includes a base 100 and a supporting column 103. The base 100 is provided at the bottom of the fixing base 101. Four supporting columns 103 are symmetrically fixed on the top of the base 100. A through hole is provided on the top of the fixing base 101. The top of the supporting column 103 passes through the through hole and is clamped with the bottom of the top plate 106. The supporting column 103 is used to protect the cylinder body 203 to prevent the cylinder body 203 from being damaged by external impact or environmental influence, thereby achieving a supporting and anti-collision effect.

[0035] In one embodiment, Figure 1-Figure 2 As shown, mounting holes 107 are symmetrically opened around the top of the base 100, and the mounting holes 107 are used to facilitate the installation of the oil cylinder, thereby enhancing the practicality of the oil cylinder.

[0036] Example 2

[0037] In one embodiment, Figure 1-Figure 3 As shown, a hose 200 is provided on the side wall of the piston rod 204, the bottom of the hose 200 is fixedly connected to the top of the top plate 106, and the top of the hose 200 is fixedly connected to the bottom of the first connector 201. When the piston rod 204 is retracting, the hose 200 follows the piston rod 204 to retract. The hose 200 can protect the extended piston rod 204 to prevent dust and other impurities from being brought into the interior of the cylinder body 203, causing the cylinder body 203 to be unable to retract normally, thereby improving the protection effect of the cylinder.

[0038] Working principle: When in use, the clamping block 310 is clamped into the installation groove 304, and the locking block 305 is clamped into the clamping groove 311 through the spring 308, so as to facilitate the clamping installation of the first protective shell 300 and the second protective shell 301. The operation is simple, the installation is quick, and the time is saved. The first protective shell 300 and the second protective shell 301 are used to protect the cylinder body 203, reduce the damage to the cylinder body 203, and extend its service life. When the piston rod 204 is retracting, the hose 200 follows the piston rod 204 to retract. The hose 200 can protect the extended piston rod 204 to prevent dust and other impurities from being brought into the interior of the cylinder body 203, which causes the cylinder body 203 to be unable to retract normally. The oil cylinder body 203 is shrunk, thereby improving the protection effect of the oil cylinder. When the oil cylinder body 203 needs to be repaired, the handle 309 is used to drive the moving rod 306 to move, so that the locking block 305 is away from the clamping block 310, and then the clamping block 310 is pulled out to release the clamping locking state, which is convenient for timely repair of the oil cylinder body 203 and improves work efficiency. When the oil cylinder generates more heat during operation, the heat sink 104 can be used to efficiently absorb and dissipate the heat transferred from the first protective shell 300 and the second protective shell 301, greatly improving the heat dissipation performance of the oil cylinder, so that the temperature in the oil cylinder is maintained in a suitable temperature range, avoiding the high temperature in the cylinder accelerating the aging of the hydraulic oil and the deterioration of the oil seal, and improving the performance of the oil cylinder.

[0039] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
