A type of turntable

Abstract

This utility model discloses a trolley turntable, relating to the field of exhibition equipment technology. The utility model includes a positioning block, with a base fixedly connected to the bottom outer wall of the positioning block. By setting a pressure block and a limiting link, the front wheel contacts the pressure block, thereby using the weight of the vehicle itself to press down on the bottom pressure block, which in turn compresses the pressure spring at the bottom. During the movement of the pressure block, it pushes the link downwards. During the movement of the limiting link, the limiting link slides along its internal groove, restricting its range of motion and allowing it to rotate around the limiting link. The front end of the limiting link then contacts the vehicle's tire, achieving a simple restriction of tire rotation through contact between the limiting link and the tire. This prevents the problem of the trolley being higher than the ground, making it difficult for the driver to see the edge of the trolley and quickly determine the vehicle's position, thus increasing the time required for vehicle adjustments and reducing efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of exhibition equipment technology, and in particular relates to a trolley turntable. Background Technology

[0002] In many fields such as modern industrial production, logistics and transportation, and exhibition, the turntable plays an irreplaceable role as an important piece of equipment. With the continuous development and progress of various industries, higher demands are being placed on the performance and functionality of the turntable.

[0003] In existing trolleys, the trolley is usually positioned at a certain height above the ground, and the driver needs to adjust the vehicle's position on the trolley after driving it onto the trolley surface. Finally, the rotation of the motor at the bottom of the trolley is remotely controlled via a controller or other means.

[0004] After the above equipment is completed, the trolley will be a certain distance above the ground, and the driver cannot see the edge of the trolley clearly, making it impossible to quickly judge the vehicle's position. This leads to increased adjustment time and reduced efficiency. Therefore, we propose a trolley turntable. Utility Model Content

[0005] The purpose of this utility model is to provide a trolley turntable that, through a positioning mechanism and a shock absorption mechanism, solves the problem that because the trolley is a certain distance above the ground, the driver cannot see the edge of the trolley clearly, making it impossible to quickly judge the vehicle's position, which leads to increased time and reduced efficiency in adjusting the vehicle.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a trolley turntable, including a positioning block, a base is fixedly connected to the bottom outer wall of the positioning block, and an auxiliary slope is fixedly connected to the outer wall of the base.

[0008] The positioning block has a positioning mechanism on its inner wall, which includes a motor. The output end of the motor is fixedly connected to a connecting shaft via a coupling. The inner wall of the connecting shaft has several limiting grooves. A positioning ring is slidably connected to the inner wall of each limiting groove. A storage tray is fixedly connected to the top outer wall of the positioning ring. The outer wall of the storage tray is rotatably connected to the outer wall of the auxiliary slope. The inner wall of the storage tray has a second limiting groove. Several pressure springs are fixedly connected to the inner wall of the storage tray. A pressure block is fixedly connected to the outer wall of one end of each pressure spring away from the storage tray. A connecting rod is rotatably connected to the outer wall of the pressure block. A limiting connecting rod is rotatably connected to the outer wall of the connecting rod away from the pressure block. A limiting rod is slidably connected to the inner wall of the limiting connecting rod. The outer wall of the limiting rod is fixedly connected to the inner wall of the storage tray. A connecting rod is fixedly connected to the outer walls of both the limiting connecting rod and the connecting rod. The positioning block has a shock absorption mechanism on its inner wall.

[0009] Furthermore, the outer wall of the fixing block is fixedly connected to the inner wall of the positioning block, and a plurality of support rods are rotatably connected to the outer wall of the fixing block. A positioning rod is rotatably connected to the outer wall of the support rod away from the fixing block.

[0010] Furthermore, a connecting block is rotatably connected to the outer wall of the other end of the positioning rod, a hydraulic damper is fixedly connected to the bottom outer wall of the connecting block, and a spring is fixedly connected to the outer wall of the hydraulic damper.

[0011] Furthermore, the inner wall of the tray is provided with a second sliding groove, and the outer wall of the roller is slidably connected to the inner wall of the second sliding groove.

[0012] Furthermore, a second support rod is rotatably connected to the bottom outer wall of the roller, and a positioning seat is rotatably connected to the outer wall of the end of the second support rod away from the roller.

[0013] Furthermore, the inner wall of the support rod is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to a second limiting rod, and the outer wall of the second limiting rod is rotatably connected to several fixed rods.

[0014] Furthermore, the bottom outer wall of several of the fixed rods rotates to form a second positioning seat, and the outer wall of the second positioning seat is fixedly connected to the inner wall of the positioning block.

[0015] Furthermore, a second connecting rod is fixedly connected to the outer wall of the fixed rod on the side away from the second positioning seat, and the outer wall of the second connecting rod is rotatably connected to the outer wall of the support rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a pressure block and a limiting link, allowing the front wheel to contact the pressure block. The weight of the vehicle itself presses down on the bottom pressure block, causing it to compress the pressure spring at the bottom. During the movement of the pressure block, the link moves downwards. As the limiting link moves, the limiting rod slides along its internal groove, restricting its range of motion and allowing it to rotate around the limiting link. The front end of the limiting link then contacts the vehicle's tire. This simple contact between the limiting link and the tire effectively restricts tire rotation, preventing situations where the trolley is elevated above the ground, making it difficult for the driver to see the edge of the trolley and quickly determine the vehicle's position, thus increasing adjustment time and reducing efficiency.

[0018] 2. This utility model incorporates a hydraulic damper and a spring. During the descent of the storage tray, multiple connecting blocks at the bottom are moved, causing them to compress the bottom spring. The elasticity of the spring alleviates the pressure on the connecting blocks. Simultaneously, the connecting blocks compress the bottom hydraulic damper, limiting their range of movement. This design reduces the pressure on the connecting blocks by compressing the bottom hydraulic damper and spring, preventing the continuous pressure from the car's weight on the turntable due to the trolley holding the car for an extended period. This prevents the connection between the motor and the turntable from breaking, thus increasing maintenance costs.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a trolley turntable, including a positioning block 1. A base 101 is fixedly connected to the bottom outer wall of the positioning block 1, and an auxiliary ramp 102 is fixedly connected to the outer wall of the base 101. By setting the auxiliary ramp 102 on the outside of the device, it is convenient for the vehicle to drive onto the surface of the storage tray 205.

[0030] The inner wall of the positioning block 1 is provided with a positioning mechanism 2, which includes a motor 201. The motor 201 is started, and its output end is fixedly connected to a connecting shaft 202 via a coupling. The inner wall of the connecting shaft 202 has several limiting grooves 204, and a positioning ring 203 is slidably connected to the inner wall of each limiting groove 204. The motor 201 drives the connecting shaft 202 to rotate, and because the positioning ring 203 is restricted by the multiple limiting grooves 204 inside the connecting shaft 202, the connecting shaft... 202 drives the positioning ring 203 to rotate. A storage tray 205 is fixedly connected to the top outer wall of the positioning ring 203. The outer wall of the storage tray 205 is rotatably connected to the outer wall of the auxiliary slope 102. A second limiting groove 212 is provided on the inner wall of the storage tray 205. Several pressure springs 207 are fixedly connected to the inner wall of the storage tray 205. A pressure block 206 is fixedly connected to the outer wall of the end of each pressure spring 207 away from the storage tray 205. When the car drives to the pressure block 206, because of the car's... The weight presses down on the pressure block 206 and squeezes the pressure spring 207 at the bottom. A connecting rod 208 is rotatably connected to the outer wall of the pressure block 206. A limit connecting rod 209 is rotatably connected to the outer wall of the end of the connecting rod 208 away from the pressure block 206. The movement of the pressure block 206 moves the connecting rod 208, causing the connecting rod 208 to drive the limit connecting rod 209 to move. A limit rod 210 is slidably connected to the inner wall of the limit connecting rod 209. Because the limit connecting rod 209 is restricted by the limit rod 210, the limit connecting rod 209 is... During the movement of rod 209, the limiting link 209 will rotate around the limiting rod 210. The outer wall of the limiting rod 210 is fixedly connected to the inner wall of the storage tray 205. The outer walls of the limiting link 209 and the link 208 are both fixedly connected to the connecting rod 211. The connecting rod 211 connects the other end of the same link 208 to the limiting link 209. The link 208 and the limiting link 209 on both sides move in the same direction and range. The inner wall of the positioning block 1 is provided with a shock absorption mechanism 3.

[0031] The shock absorption mechanism 3 includes a fixed block 301. The outer wall of the fixed block 301 is fixedly connected to the inner wall of the positioning block 1. Several support rods 302 are rotatably connected to the outer wall of the fixed block 301. A positioning rod 303 is rotatably connected to the outer wall of one end of the support rod 302 away from the fixed block 301. A connecting block 304 is rotatably connected to the outer wall of the other end of the positioning rod 303. Because the connecting block 304 is in contact with the bottom of the storage tray 205, when the storage tray 205 is pressed down, the connecting block 304 will drive the positioning rod 303 to move and push the support rod 302 to rotate around the fixed block 301. A liquid is fixedly connected to the bottom outer wall of the connecting block 304. A hydraulic damper 306 has a spring 305 fixedly connected to its outer wall. The outer wall of the spring 305 is fixedly connected to the outer wall of the fixed block 301. When the connecting block 304 moves downward, the spring 305 automatically compresses to limit the movement range of the connecting block 304. The elasticity of the spring 305 itself relieves the pressure on the storage tray 205. The inner wall of the storage tray 205 has a second sliding groove 314. The outer wall of the roller 309 is slidably connected to the inner wall of the second sliding groove 314. The roller 309 slides in the second sliding groove 314 inside the storage tray 205 to stabilize the rotation of the storage tray 205.

[0032] A second support rod 308 is rotatably connected to the bottom outer wall of the roller 309. A positioning seat 307 is rotatably connected to the outer wall of the end of the second support rod 308 away from the roller 309. The roller 309 is extended to the second slide groove 314 via the second support rod 308, allowing the roller 309 to slide along the interior of the second slide groove 314. A slide groove 312 is formed on the inner wall of the support rod 302. A second limiting rod 313 is slidably connected to the inner wall of the slide groove 312. Several fixed rods 310 are rotatably connected to the outer wall of the second limiting rod 313. The second limiting rod 313 slides along the slide groove 312 inside the support rod 302, thereby supporting the support rod 302 and preventing excessive pressure from causing excessive rotation angle and failure to support it. The bottom outer walls of the several fixed rods 310 rotate to form a second positioning seat 307. The outer wall of the second positioning seat 315 is fixedly connected to the inner wall of the positioning block 1. The outer wall of the fixing rod 310 away from the second positioning seat 315 is fixedly connected to the second connecting rod 311. The outer wall of the second connecting rod 311 is rotatably connected to the outer wall of the support rod 302. The positioning rod 303 is connected through the second connecting rod 311. When the positioning rod 303 moves, the second connecting rod 311 moves and pushes the fixing rod 310 to rotate around the second positioning seat 315, so that the fixing rod 310 shares the pressure on the positioning rod 303.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, the vehicle is driven along the auxiliary ramp 102 to the surface of the storage tray 205, with the front wheels contacting the pressure block 206. The weight of the vehicle presses down on the bottom pressure block 206, causing it to compress the pressure spring 207 at the bottom. During the movement of the pressure block 206, the connecting rod 208 is pushed downwards. Because the groove inside the storage tray 205 is not deep enough, the connecting rod 208 will push the limiting connecting rod 209 to move due to the movement of the pressure block 206. During the movement of the limiting connecting rod 209, the limiting rod 210 will slide along the internal groove of the limiting connecting rod 209. Since the limiting rod 210 is fixed inside the storage tray 205, the limiting connecting rod... During the movement of 209, the limiting rod 210 restricts the movement range of the limiting link 209. Driven by the link 208, the limiting link 209 rotates around the limiting rod 210, causing the front end of the limiting link 209 to protrude from the storage tray 205 and contact the car's tires through rotation. This simple restriction of the car tires' rotation by the limiting link 209 effectively positions the car. The movement of the link 208 and the limiting link 209 also drives the connecting rod 211 to move. Both ends of the connecting rod 211 are connected to the link 208 and the limiting link 209, which are of the same size and material. Therefore, the movement of the connecting rod 211 causes the storage tray 205 to approach the limiting link 209 near the rear wheels of the car, which in turn contacts the wheels in the same way. The device contacts the tire, thus restricting its movement. Then, via mobile software, the bottom motor 201 is activated, causing the connecting shaft 202 to rotate, which in turn rotates the positioning ring 203, causing the storage tray 205 to rotate smoothly. During the rotation of the storage tray 205, the roller 309, supported by the second support rod 308, slides along the second groove 314 inside the storage tray 205, stabilizing the rotation amplitude. When a car drives onto the surface of the storage tray 205, its weight pushes the tray downwards, causing it to sink. This, in turn, pushes the positioning ring 203 to move. However, the positioning ring 203's movement is restricted by the limiting groove 204. The positioning ring 203 can only slide along the limiting groove 204 and is always connected to the connecting shaft 202, allowing the motor 201 to drive the positioning ring 203 to rotate via the connecting shaft 202. During the sinking of the storage tray 205, it will push multiple connecting blocks 304 on the bottom surface to move, and the connecting blocks 304 will compress the bottom spring 305. The elasticity of the spring 305 will relieve the pressure on the connecting blocks 304. At the same time, the connecting blocks 304 will push the bottom hydraulic damper 306 to compress, thereby limiting the range of movement of the connecting blocks 304. During the movement of the connecting blocks 304, it will push the positioning rods 303 on both sides to move, and the positioning rods 303 will push the support rod 302 to rotate around the fixed block 301.Simultaneously, the positioning rod 303 and the support rod 302 will move closer together due to the movement of the connecting block 304. This movement causes the positioning rod 303 to push the second connecting rod 311, while simultaneously causing the fixed rod 310 to rotate around the second positioning seat 315. The connection between the fixed rod 310 and the second connecting rod 311 shares the pressure on the positioning rod 303. At the same time, the second limiting rod 313 will slide along the groove 312 inside the support rod 302, thus supporting and restricting the support rod 302 and preventing excessive bending. When the positioning rod 303 moves, it will cause the positioning seat 307 to move. The movement of the positioning seat 307 will then cause the second support rod 308 to move and pull the rollers 309 to both sides. Because the rollers 309 are restricted by the second groove 314, they will move towards the connecting block 304, causing the second support rod 308 to rotate around the positioning seat 307. This ensures that the rollers 309 can always stably rotate the tray 205.
