DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Reference Figures 1-3 The utility model provides a kind of scissor lift platform, including lifting mechanism 2, lifting mechanism 2 includes lower support seat 206 and upper support seat 201, two moving slide rails 211 are fixedly arranged in lower support seat 206 inside one side, two moving slide rails 211 upper end are slidably provided with sliding block 207, two fixed blocks 210 are fixedly arranged in lower support seat 206 inside side away from moving slide rail 211, two lower X-shaped frames 205 are hingedly arranged between two fixed blocks 210 and two sliding blocks 207 respectively, two upper X-shaped frames 204 are hingedly arranged in the upper end of two lower X-shaped frames 205, two stable slide rods 202 are fixedly arranged in the upper end of lower support seat 206, upper support seat 201 is slidably arranged in the outer portion of two stable slide rods 202, two fixed blocks 210, two sliding blocks 207 and two moving slide rails 211 are provided with two groups, another group of fixed block 210, sliding block 207 and moving slide rail 211 are arranged between the lower end of upper support seat 201 and two upper X-shaped frames 204, inner stabilizing frame 209 is fixedly arranged in the inside of lower support seat 206 close to fixed block 210 side, two air cylinders 208 are fixedly arranged in the side of inner stabilizing frame 209, two air cylinders 208 other end are fixedly connected to the side of two sliding blocks 207 respectively, middle connecting shaft 203 is rotatably arranged in the hinged position between two upper X-shaped frames 204 and two lower X-shaped frames 205.

[0024] Specifically, when cylinder 208 is activated, the extension and retraction of the piston rod of cylinder 208 causes the sliding block 207 to slide on the moving slide rail 211. Utilizing the lever principle, the movement of the sliding block 207 causes the lower X-shaped frame 205 to change angle. Through the intermediate connecting shaft 203, the lower X-shaped frame 205 drives the upper X-shaped frame 204 to move in tandem, thereby realizing the lifting and lowering of the upper support seat 201 along the stabilizing slide rod 202. This scissor-type structure design can efficiently convert the linear motion of cylinder 208 into the vertical lifting and lowering motion of the platform. The scissor-type structure has good stability and load-bearing capacity, ensuring that the platform remains stable during lifting and lowering. The cooperation between the moving slide rail 211 and the sliding block 207 makes the lifting and lowering action smoother and reduces jamming. The stabilizing slide rod 202 not only guides the upper support seat 201 but also enhances the stability of the overall structure, preventing the platform from shifting during lifting and lowering. The design of two sets of fixed blocks 210, sliding blocks 207, moving slide rails, and intermediate connecting shaft 203 further optimizes the force transmission and improves the reliability and durability of the lifting mechanism 2.

[0025] Reference Figure 1 , 2 4. A platform mechanism 1 is fixedly installed on the upper end of the upper support seat 201. The platform mechanism 1 includes a lifting guardrail 101. A support frame 103 is fixedly installed on one side of the lifting guardrail 101. A tool frame 104 is snapped into the lower end of the support frame 103. A pull rope 102 is fixedly installed on the upper end of the tool frame 104. A winding disc 105 is rotatably installed on the inner surface of the lifting guardrail 101 near the support frame 103. A rotating handle 106 is fixedly installed on one side of the winding disc 105. The pull rope 102 is wound inside the winding disc 105.

[0026] Specifically, by rotating the handle 106 on one side of the winding reel 105, the operator rotates the reel 105, thereby controlling the raising and lowering of the rope 102 and ultimately moving the tool frame 104 up and down along the support frame 103. This design utilizes a simple pulley and rope principle, making it easy to operate. The tool frame 104 allows operators to retrieve and place tools from the ground without frequent platform adjustments, significantly improving work efficiency. The tool frame 104 and support frame 103 are connected by a snap-fit ​​mechanism, facilitating disassembly and installation, and making cleaning and replacement of the tool frame 104 convenient. The design of the handle 106 and winding reel 105 makes operation simple and effortless, allowing even less physically strong operators to operate easily, enhancing the equipment's usability. The lifting guardrail 101 provides safety for operators, preventing accidental falls during work.

[0027] Working principle: When the lifting platform needs to rise or fall, the cylinder 208, located inside the lower support 206 near the fixed block 210, is activated. The cylinder 208 operates, its piston rod extending or retracting, causing the sliding block 207, fixedly connected to it, to slide on the moving slide rail 211. Due to the movement of the sliding block 207, the lower X-shaped frame 205, hinged to it, moves accordingly. The expansion or contraction of the lower X-shaped frame 205 drives the upper X-shaped frame 204 to perform corresponding actions via the intermediate connecting shaft 203. The two lower X-shaped frames 205 and the upper X-shaped frame 204 work together, ultimately pushing the upper support 201 to rise or fall along the stabilizing slide bar 202, thereby realizing the lifting and lowering of the platform mechanism 1.

[0028] The operation is more convenient when workers on platform mechanism 1 need to retrieve or place tools on the ground. Workers simply pull the pull rope 102 wound around the winding reel 105, causing the tool frame 104 to slide down along the support frame 103 to the ground. After the workers below place the required tools into the tool frame 104, the workers on the platform turn the rotating handle 106 on one side of the winding reel 105, causing the winding reel 105 to rotate, winding the pull rope 102 around it, and thus raising the tool frame 104 back to the platform for easy retrieval.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
