Description

Technical Field

[0001] This utility model relates to the field of PP experimental platform technology, specifically to a PP experimental platform that is easy to install and has an adjustable structure. Background Technology

[0002] PP material is polypropylene, which is a non-toxic, odorless, tasteless, milky white, highly crystalline polymer. It is one of the lightest types of plastics and is a thermoplastic resin made from propylene through an addition polymerization reaction. It is widely used in industry and daily life.

[0003] Patent publication number CN214765603U discloses a PP experimental platform, which consists of a PP board, a second cabinet, a first cabinet, a functional cabinet, and a storage rack.

[0004] To address the issue of a fixed and unadjustable area, existing technology involves installing casters at the bottom of the storage rack. Pulling a handle allows the rack to shift on top of the PP board, resulting in smoother sliding. The limiting function of the slider further enhances the rack's stability. This allows for adjustments to the experimental area on top of the PP board based on actual needs. However, this approach still presents the problem of not being able to securely install experimental items, leading to poor stability. Utility Model Content

[0014] A further improvement of the present invention is that the adjustment mechanism further includes a lifting plate, which is fixedly installed on the surface of the base and movably installed on the surface of the slide rail. A stop block is fixedly installed on the surface of the lifting plate, and the stop block is adapted to the limiting block.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a PP experimental platform that is easy to install and has an adjustable structure. It employs a platform, a storage slot, a boss, a stepper motor, a bidirectional lead screw, a guide plate, a slider, a fixed seat, an electric telescopic rod, a movable seat, an adjusting column, a spring, and a partition. A fixed frame at the bottom of the stepper motor connects the stepper motor to the boss, maintaining the stability of the stepper motor during operation. The storage slot on the platform surface allows equipment to be placed inside, allowing items to fall off the platform. Experimental equipment or objects are placed between two sets of movable seats. The stepper motor drives the bidirectional lead screw to rotate, causing the slider to move closer to the center along the guide plate, clamping the object. When the adjusting column on the movable seat surface contacts the object, the evenly distributed adjusting columns move inward according to the contact point, compressing the spring. Simultaneously, the partitions, evenly distributed in a cross pattern, guide the adjusting columns. At this point, the adjusting column on the side in contact with the object clamps the object, while the adjusting column on the other side blocks and limits the object, preventing it from moving forward, backward, left, or right. The adjusting column is made of nitrile rubber, making it lightweight. Wear-resistant and with a certain degree of elasticity, the device will not damage the items when fixing them. At the same time, the device can adjust the position of the movable seat left and right through the electric telescopic rod on the surface of the fixed seat, which improves the adaptability of the device.

It adopts the cooperation of a threaded column, a threaded drum, a lifting plate, a stop block, a limiting block, a first pulley, a cabinet, a storage box, a slide rail, a second pulley, a belt, and a motor. The motor is fixed inside the cabinet to keep it stable during operation. When the height of the device needs to be adjusted, the motor drives the second pulley to rotate, which in turn drives the first pulley to rotate. This causes the threaded drum to move upward on the surface of the threaded column, which in turn causes the cabinet and the limiting block to move upward, and the slide rail to slide inside the lifting plate, thereby adjusting the height. The maximum extension height is reached when the limiting block contacts the stop block. At the same time, the device utilizes the spare space in the cabinet by setting up a storage box to store experimental equipment and other items, improving the adaptability of the device.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5 As shown, this utility model provides a PP experimental platform that is easy to install and has an adjustable structure, including a base 1. An adjustment mechanism 3 is provided on the surface of the base 1, and a clamping and mounting mechanism 2 is provided on the surface of the adjustment mechanism 3. The clamping and mounting mechanism 2 includes a platform 201, which is fixedly mounted on the surface of the adjustment mechanism 3. A storage groove 202 is provided on the surface of the platform 201. A boss 203 is fixedly mounted on the side of the platform 201 away from the storage groove 202. Two sets of bosses 203 are provided, symmetrically distributed on one side of the platform 201. A stepper motor 204 is fixedly mounted on the surface of the boss 203. A bidirectional lead screw 205 is fixedly mounted on the output end of the stepper motor 204. The bidirectional lead screw 205 is movably mounted on the surface of the boss 203. A slider 207 is threadedly connected to the surface of the bidirectional lead screw 205. The slider 207 is provided with two... The sliders 207 are symmetrically distributed on the surface of the bidirectional lead screw 205. A guide plate 206 is movably mounted on the surface of the sliders 207. The guide plate 206 is fixedly mounted on the surface of the boss 203. A fixed seat 208 is fixedly mounted on the surface of the sliders 207. An electric telescopic rod 209 is fixedly mounted on the side of the fixed seat 208 near the storage slot 202. A movable seat 210 is fixedly mounted on the telescopic end of the electric telescopic rod 209. The movable seat 210 is movably mounted on the surface of the electric telescopic rod 209. A partition 213 is fixedly mounted inside the movable seat 210. Multiple partitions 213 are provided. The partitions 213 are evenly and crosswise distributed inside the movable seat 210. A spring 212 is fixedly mounted inside the movable seat 210. An adjusting column 211 is fixedly mounted on one end of the spring 212. The adjusting column 211 is movably mounted inside the movable seat 210.

[0027] In this embodiment, a fixing bracket is provided at the bottom of the stepper motor 204 to connect the stepper motor 204 to the boss 203, maintaining the stability of the stepper motor 204 during driving. A storage slot 202 is provided on the surface of the platform 201 to place the equipment to be used. When moving items, they fall off the test bench. The experimental equipment or objects are placed between the two sets of movable seats 210. The stepper motor 204 drives the bidirectional lead screw 205 to rotate, causing the slider 207 to move closer to the center along the guide plate 206, allowing the movable seats 210 to clamp and install the items. The bidirectional lead screw... 205 is a fine-pitch lead screw with parameters M1.6×1.0, designed to achieve a self-locking function. When the adjusting posts 211 on the surface of the movable seat 210 contact the object, the evenly distributed adjusting posts 211 move inward according to the contact point with the object, compressing the spring 212. Simultaneously, the partition plates 213, evenly distributed in a cross pattern, guide the adjusting posts 211. At this point, the side of the adjusting post 211 that contacts the object clamps the object, while the side that does not contact the object blocks and limits its movement, preventing it from moving forward, backward, left, or right. The adjusting posts 211 are made of nitrile rubber, which is lightweight, wear-resistant, and has a certain degree of elasticity, ensuring that the object is not damaged when it is fixed. Furthermore, the device allows for left and right adjustment of the movable seat 210 via the electric telescopic rod 209 on the surface of the fixed seat 208. It should be noted that the electric telescopic rod 209 is made of high-strength alloy, enabling it to withstand a stress of approximately 30kg, preventing damage during clamping and improving the adaptability of the device.

[0028] Example 2

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjusting mechanism 3 includes a cabinet 307, which is fixedly installed at the bottom of the platform 201. A storage box 308 is provided inside the cabinet 307. Slide rails 309 are fixedly installed on both sides of the cabinet 307. Limiting blocks 305 are symmetrically distributed at the lower ends of both sides of the cabinet 307. A motor 312 is fixedly installed at the upper end of the cabinet 307. A second pulley 310 is fixedly installed at the output end of the motor 312. The second pulley 310 is movably installed inside the cabinet 307. The surface of the second pulley 310 is movably mounted... The system is equipped with a belt 311, on which a first pulley 306 is movably mounted. A threaded drum 302 is fixedly mounted at the bottom end of the first pulley 306. The threaded drum 302 is movably mounted at the bottom end of the cabinet 307. A threaded post 301 is threadedly connected inside the cabinet 307. The threaded post 301 is fixedly mounted on the surface of the base 1. The adjustment mechanism 3 also includes a lifting plate 303, which is fixedly mounted on the surface of the base 1 and movably mounted on the surface of the slide rail 309. A stop block 304 is fixedly mounted on the surface of the lifting plate 303 and is adapted to a limit block 305.

[0030] In this embodiment, the motor 312 is fixed inside the cabinet 307 to ensure stability during operation. When the height of the device needs to be adjusted, the motor 312 drives the second pulley 310 to rotate, causing the belt 311 on its surface to drive the first pulley 306 to rotate. This causes the threaded drum 302 to move upward on the surface of the threaded column 301. The threaded column 301 has a trapezoidal thread with a pitch of 4mm to achieve its self-locking function and prevent the test bench from falling, thus ensuring a load-bearing capacity of 500kg. The threaded column 301 drives the cabinet 307 and the limiting block 305 to move upward, and causes the slide rail 309 to slide inside the lifting plate 303, thereby adjusting its height. The maximum extension height is reached when the limiting block 305 contacts the stop block 304. At the same time, the device utilizes the spare space of the cabinet 307 by setting up a storage box 308 to store experimental equipment and other items, improving the adaptability of the device.

[0031] The working principle of this easy-to-install and adjustable PP experimental platform will be explained in detail below.

[0032] like Figure 1-5As shown, a fixing bracket is provided at the bottom of the stepper motor 204 to connect the stepper motor 204 to the boss 203, maintaining the stability of the stepper motor 204 during driving. A storage slot 202 is provided on the surface of the platform 201 to place the equipment to be used. When moving items, they fall off the test bench. Experimental equipment or objects are placed between the two sets of movable seats 210. The stepper motor 204 drives the bidirectional lead screw 205 to rotate, causing the slider 207 to move closer to the center along the guide plate 206, allowing the movable seats 210 to clamp and install the items. The bidirectional lead screw 205... 5 is a fine-tooth lead screw with parameters M1.6×1.0 to achieve a self-locking function. When the adjusting post 211 on the surface of the movable seat 210 contacts the object, the evenly distributed adjusting posts 211 move inward according to the contact point of the object, compressing the spring 212. At the same time, the partition plates 213 are evenly distributed in a cross shape to guide the adjusting posts 211. At this time, the side of the adjusting post 211 that contacts the object clamps the object, while the adjusting posts 211 that do not contact the object block and limit the object, so that it cannot move forward, backward, left, or right. The adjusting post 211 is made of nitrile rubber, which is lightweight. Wear-resistant and with a certain degree of elasticity, the device prevents damage to items during fixation. The movable seat 210 can be adjusted left and right via the electric telescopic rod 209 on the surface of the fixed seat 208. It should be noted that the electric telescopic rod 209 is made of high-strength alloy, enabling it to withstand approximately 30kg of stress, preventing damage during clamping. It is fixed inside the cabinet 307 by a motor 312, ensuring stability during operation. When the height of the device needs adjustment, the motor 312 drives the second pulley 310 to rotate, causing the belt 311 on its surface to drive the first pulley 306 to rotate. The movement causes the threaded drum 302 to move upward on the surface of the threaded column 301. The threaded column 301 has a trapezoidal thread with a pitch of 4mm to achieve its self-locking function and prevent the test bench from falling, thus enabling it to bear a load of 500kg. The threaded column 301 drives the cabinet 307 and the limiting block 305 to move upward, and causes the slide rail 309 to slide inside the lifting plate 303, thereby adjusting its height. When the limiting block 305 contacts the stop block 304, it is the maximum extension height. At the same time, the device utilizes the empty space of the cabinet 307 by setting up a storage box 308, which allows experimental equipment and other items to be stored, improving the adaptability of the device.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
