Description

Technical Field

[0001] The utility model relates to a tensioning oil cylinder, in particular to a tensioning oil cylinder with a fixing mechanism, belonging to the technical field of tensioning oil cylinders. Background Art

[0002] A tensioner cylinder is a hydraulic cylinder used to provide tension or tightening force. It is mainly used to maintain proper tension on tracks or chains to ensure the normal operation and stability of the equipment.

[0003] According to a tensioning cylinder with a fixing mechanism with announcement number CN220227372U, it mainly realizes the function of convenient maintenance through the coordinated use of an installation box, a cylinder body, a fixing plate, a clamping plate, a knob, a worm, a worm gear, a threaded rod, a threaded tube, a vertical rod, a pulley, a push block, a limit rod, a limit groove, a sliding sleeve, a sliding rod and a spring, and solves the problem that the existing tensioning cylinder is not easy to disassemble and maintain, and multiple sets of bolts need to be used for fixing during the installation process, and the cylinder needs to be oiled and maintained regularly, which is very inconvenient during the disassembly process.

[0004] Although the above-mentioned documents can rely on the control of the worm and worm wheel for relatively convenient disassembly and fixation, we can understand in real life that the worm and worm wheel will have certain wear during their use. However, during long-term use, when the wear is more serious, the worm and worm wheel will have thread slippage, resulting in the worm being unable to effectively drive the worm wheel to rotate, which not only brings certain difficulties when people disassemble and fix the oil cylinder, but also reduces the fixing effect of the oil cylinder. Utility Model Content

[0005] The utility model provides a tensioning oil cylinder with a fixing mechanism to solve the problem in the prior art that the worm and the worm wheel slip and thus cause great inconvenience when people disassemble the oil cylinder.

[0006] The utility model is implemented by the following technical scheme: a tensioning oil cylinder with a fixing mechanism, comprising a tensioning oil cylinder body, a mounting plate is arranged below the tensioning oil cylinder body, a symmetrical mounting mechanism is arranged on the upper surface of the mounting plate, the mounting mechanism comprises a movable plate, both ends of the movable plate are fixedly connected with an L-shaped frame, the outer surfaces of the two L-shaped frames are fixedly connected with a limiting block, and the inner walls of the two limiting blocks are rotatably connected with a rotating shaft;

[0007] The outer surfaces of the two rotating shafts are fixedly connected with symmetrical auxiliary wheels, the outer surface of the movable plate is fixedly connected with symmetrical sliding rods, the outer surfaces of the two sliding rods are slidably connected with fixed cylinders, the inner walls of the two fixed cylinders are fixedly connected with springs, and the outer surfaces of the two fixed cylinders are fixedly connected with U-shaped pads. As the movable plate moves, the sliding rod can be driven to slide into the fixed cylinder, and under the action of the sliding rod, the spring can be squeezed.

[0008] Furthermore, a limit plate is fixedly connected to the bottom surface of the tensioning oil cylinder body, and symmetrical positioning holes are formed on the upper surface of the limit plate.

[0009] Specifically, a symmetrical positioning column is fixedly connected to the upper surface of the mounting plate, and the positioning column is matched with the positioning hole. Through the matching arrangement of the positioning hole and the positioning column, the positioning of the tensioning cylinder body during installation and the lateral limitation of the tensioning cylinder body can be achieved.

[0010] Furthermore, four fixing feet are fixedly connected to the outer surface of the mounting plate, and a threaded hole is provided on the outer surface of each of the fixing feet, through which people can install the mounting plate on mechanical equipment by screws.

[0011] Specifically, the spring is fixedly connected to the sliding rod, and the two U-shaped pads are fixedly connected to the upper surface of the mounting plate. As the sliding rod slides into the fixed tube, the spring can be squeezed. At this time, the spring provides an elastic force to the sliding rod, and the fixed tube can be supported by the U-shaped pad.

[0012] Preferably, the four fixing feet are respectively located at four corners of the mounting plate, and the auxiliary wheels are in contact with the upper surface of the mounting plate.

[0013] The utility model provides a tensioning oil cylinder with a fixing mechanism, which has the following beneficial effects:

[0014] This tensioning cylinder with a fixing mechanism, through the coordinated arrangement among the tensioning cylinder body, the mounting plate, the mounting mechanism and the limit plate, can make the device no longer rely on the coordinated use of the worm and the worm wheel to fix and disassemble the tensioning cylinder body, thereby effectively avoiding the situation where the worm and the worm wheel slip and the worm cannot effectively drive the worm wheel to rotate. It not only makes it easier for people to fix and disassemble the tensioning cylinder body, but also further ensures the fixing effect of the tensioning cylinder body.

[0015] The tensioning oil cylinder with a fixing mechanism can make it easier for people to fix the tensioning oil cylinder body through the matching arrangement among the tensioning oil cylinder body, the limit plate, the limit block, the movable plate, the sliding rod, the fixing tube and the spring. As the tensioning oil cylinder body moves downward, the limit block can be driven to move under the action of the limit plate until the bottom surface of the limit block is flush with the upper surface of the limit plate. At this time, under the action of the elastic force of the spring, the limit block can be driven to reset, thereby limiting the limit plate, thereby achieving the fixation of the tensioning oil cylinder body.

[0025] The embodiment of the utility model provides a tensioning oil cylinder with a fixing mechanism.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, including a tensioning oil cylinder body 1, a mounting plate 2 is arranged below the tensioning oil cylinder body 1, a symmetrical mounting mechanism 3 is arranged on the upper surface of the mounting plate 2, the tensioning oil cylinder body 1 can be fixed by the mounting mechanism 3, the mounting mechanism 3 includes a movable plate 301, both ends of the movable plate 301 are fixedly connected with L-shaped frames 302, and the movement of the movable plate 301 can drive the movement of the L-shaped frames 302, the outer surfaces of the two L-shaped frames 302 are fixedly connected with limit blocks 303, the inner walls of the two limit blocks 303 are rotatably connected with a rotating shaft 304, and the front end of the limit block 303 is chamfered;

[0027] The outer surfaces of the two rotating shafts 304 are fixedly connected with symmetrical auxiliary wheels 305, the outer surface of the movable plate 301 is fixedly connected with symmetrical sliding rods 306, the outer surfaces of the two sliding rods 306 are slidably connected with fixed cylinders 307, the inner walls of the two fixed cylinders 307 are fixedly connected with springs 308, and the outer surfaces of the two fixed cylinders 307 are fixedly connected with U-shaped pads 309. As the movable plate 301 moves, the sliding rods 306 can be driven to slide into the fixed cylinders 307, and under the action of the sliding rods 306, the springs 308 can be squeezed.

[0028] Please refer to Figure 3 The bottom surface of the tensioning oil cylinder body 1 is fixedly connected with a limit plate 4, and the upper surface of the limit plate 4 is provided with symmetrical positioning holes 5.

[0029] See also Figure 3 A symmetrical positioning column 6 is fixedly connected to the upper surface of the mounting plate 2, and the positioning column 6 is adapted to the positioning hole 5. Through the coordinated setting of the positioning hole 5 and the positioning column 6, the positioning of the tensioning cylinder body 1 during installation and the lateral limitation of the tensioning cylinder body 1 can be achieved.

[0030] Please refer to Figure 3 Four fixing feet 7 are fixedly connected to the outer surface of the mounting plate 2. A threaded hole 8 is formed on the outer surface of each fixing foot 7. The threaded hole 8 enables people to install the mounting plate 2 on mechanical equipment by screws.

[0031] Please refer to Figure 4 The spring 308 is fixedly connected to the sliding rod 306, and the two U-shaped pads 309 are fixedly connected to the upper surface of the mounting plate 2. As the sliding rod 306 slides into the fixed tube 307, the spring 308 can be squeezed.

At this time, another staff only needs to pull the tensioning oil cylinder 1 upward to disassemble the tensioning oil cylinder 1, so that the device no longer relies on the cooperation of the worm and the worm wheel to fix and disassemble the tensioning oil cylinder 1, thereby effectively avoiding the situation where the worm and the worm wheel are slipped and the worm cannot effectively drive the worm wheel to rotate. It not only makes it easier for people to fix and disassemble the tensioning oil cylinder 1, but also further ensures the fixing effect of the tensioning oil cylinder 1.
