Description

Technical Field

[0001] This utility model relates to the technical field of bottom support structure for platform screen doors, specifically a bottom support structure for rail transit platform screen doors. Background Technology

[0002] The bottom support mechanism for rail transit platform screen doors is a specially designed mechanism used to support and stabilize the platform screen doors, ensuring their safety and stability during use. The bottom support mechanism for rail transit platform screen doors is a complex and delicate mechanical system. Its design and use need to take into account a variety of factors, including the weight, size, frequency of use, and passenger safety of the platform screen doors. With the advancement of technology and continuous innovation, the design of these support mechanisms is also constantly being optimized and improved.

[0003] The current patent number CN222179484U discloses a bottom support mechanism for rail transit platform doors. This device inserts a plate into the side groove and slot of the platform and fixes the plate with bolts that cooperate with the first and second fixing holes, thereby greatly reducing the difficulty of installing the bottom support mechanism for rail transit platform doors. However, when there are too many platform doors that need to be installed or disassembled, this device still needs to use a wrench to turn the bolts one by one for installation and disassembly, which is time-consuming and labor-intensive, reducing work efficiency. Therefore, it needs to be improved. Summary of the Invention

[0004] This utility model provides a bottom support structure for rail transit platform doors, which can facilitate locking and unlocking by setting up locking blocks and driving mechanisms to move synchronously towards or away from each other.

[0005] To achieve the above objectives, a bottom support structure for a rail transit platform door is provided, including a platform body. An installation groove is formed on the upper surface of the platform body, and an installation seat is provided inside the installation groove. A locking groove is formed inside the installation seat, and the platform door body is fixedly installed on the upper surface of the installation seat. A sliding groove is formed inside the platform body, and the sliding groove communicates with the installation groove. Two locking blocks are slidably connected inside the sliding groove, distributed on both sides of the installation seat. A driving mechanism is provided on the inner side of the sliding groove away from the locking blocks, and the driving mechanism is fixedly connected to the locking blocks. By configuring the locking blocks and the driving mechanism to cooperate with each other, the locking blocks can be driven to move synchronously towards or away from each other for convenient locking and unlocking.

[0006] According to the aforementioned bottom support structure for a rail transit platform door, the driving mechanism includes a fixed plate, a driving block, a connecting plate, a sliding plate, a limiting post, a fixed shell, a lead screw, a rotating disk, and a limiting groove. The fixed plate is fixedly connected to the locking block, and the limiting post is slidably connected to the inner side of the fixed plate. Both ends of the limiting post are fixedly connected to the inner surface of the sliding groove. By setting the mutual cooperation between the limiting post and the fixed plate, the limiting post limits the fixed plate, making the movement of the locking block driven by the fixed plate more stable.

[0007] According to the aforementioned bottom support structure for a rail transit platform door, a spring is sleeved on the outer side of the limiting post. The two ends of the spring are fixedly connected to the side of the fixed plate that is away from each other and to the surface of the sliding groove, respectively. By setting up the interaction between the spring and the fixed plate, the spring pushes the fixed plate to always be in a state of close proximity, thereby completing the locking mechanism.

[0008] According to the aforementioned bottom support structure for a rail transit platform door, the connecting plate is slidably connected to the side of the sliding groove away from the locking block, and the driving block is fixedly connected to the side of the connecting plate near the fixed plate. Two driving blocks are provided and symmetrically arranged. The sides of the driving blocks that are far apart from each other are set at an angle, and the sides of the fixed plates that are close to the driving blocks and approach each other are set at an inclination angle. The connecting plate drives the driving blocks to move towards the locking block, thereby causing the angle of the driving block to contact the inclination angle of the fixed plate. As the angles gradually move away from each other, the fixed plates move away from each other, thus completing the disassembly.

[0009] According to the aforementioned bottom support structure for a rail transit platform door, the limiting groove is located on the upper end of the platform body, away from the sliding groove. The sliding plate is slidably connected to the inner side of the limiting groove, and the lower end of the sliding plate is fixedly connected to the upper surface of the connecting plate. By setting the mutual cooperation between the sliding plate and the limiting groove, the sliding plate is limited, making the movement of the connecting plate by the sliding plate more stable.

[0010] According to the aforementioned bottom support structure for a rail transit platform door, the fixed shell is fixedly connected to the top surface of the platform body. The inner surface of the fixed shell is slidably connected to the upper outer side of the sliding plate. The lead screw is threadedly connected to the upper inner side of the sliding plate, and both ends of the lead screw pass through the sliding plate and are rotatably connected to the two sides of the fixed shell. By setting the mutual cooperation between the lead screw and the sliding plate, users can rotate the lead screw from above the platform body for installation and disassembly, thus completing the process without significant positional movement, thereby facilitating use.

[0011] According to the aforementioned bottom support structure for a rail transit platform door, the rotating disk is fixedly connected to the end of the lead screw away from the platform door body, and the rotating disk is made of rubber. By configuring the interaction between the rotating disk and the lead screw, it makes it easier for the user to rotate the lead screw.

[0012] According to the aforementioned bottom support structure for a rail transit platform door, the fixed shell has insertion holes on the side near the rotating disk. These insertion holes are arranged in a plurality of holes and are evenly distributed in a ring at equal angles. The surface of the rotating disk has holes that fit into the insertion holes, and a pin is provided inside each hole. Through the cooperation between the pin and the hole, the rotating disk is limited, reducing the problem of the rotating disk rotating on its own.

[0013] The beneficial effects of this utility model are as follows: By setting up a locking block, the mutual cooperation between the driving mechanism and the locking groove, the driving mechanism drives the locking block to move synchronously towards or away from each other, thereby allowing the locking block to contact and separate from the inner side of the locking groove. This facilitates the installation and disassembly of the platform door body without the need to use bolts and wrenches for individual fixing.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] Reference Figures 1 to 5 This utility model provides a bottom support structure for a rail transit platform door, which includes a platform body 1. The upper surface of the platform body 1 is provided with an installation groove 2. An installation seat 3 is provided inside the installation groove 2. An engagement groove 4 is provided inside the installation seat 3. A platform door body 5 is fixedly installed on the upper surface of the installation seat 3. A sliding groove 6 is provided inside the platform body 1. The sliding groove 6 is connected to the installation groove 2. An engagement block 7 is slidably connected inside the sliding groove 6. Two engagement blocks 7 are provided and distributed on both sides of the installation seat 3. A driving mechanism 22 is provided inside the sliding groove 6 away from the engagement block 7. The driving mechanism 22 is fixedly connected to the engagement block 7.

[0025] The drive mechanism 22 includes a fixed plate 2201, a drive block 2202, a connecting plate 2203, a sliding plate 2204, a limiting post 2205, a fixed shell 2206, a lead screw 2207, a rotating disk 2208, and a limiting groove 2209. The fixed plate 2201 is fixedly connected to the locking block 7, and the limiting post 2205 is slidably connected to the inner side of the fixed plate 2201. The two ends of the limiting post 2205 are fixedly connected to the inner surface of the sliding groove 6.

[0026] The connecting plate 2203 is slidably connected to the sliding groove 6 on the side away from the locking block 7. The driving block 2202 is fixedly connected to the connecting plate 2203 on the side close to the fixing plate 2201. There are two driving blocks 2202 that are symmetrical to each other. The side of the driving blocks 2202 that is far away from each other is set at an angle. The side of the fixing plate 2201 that is close to the driving blocks 2202 and that is close to each other is set at an inclination angle.

[0027] A limiting groove 2209 is formed on the upper end of the platform body 1 away from the sliding groove 6. A sliding plate 2204 is slidably connected to the inner side of the limiting groove 2209. The lower end of the sliding plate 2204 is fixedly connected to the upper surface of the connecting plate 2203. A fixing shell 2206 is fixedly connected to the top surface of the platform body 1. The inner surface of the fixing shell 2206 is slidably connected to the outer side of the upper end of the sliding plate 2204. A lead rod 2207 is threadedly connected to the inner side of the upper end of the sliding plate 2204. Both ends of the lead rod 2207 pass through the sliding plate 2204 and are rotatably connected to both sides of the fixing shell 2206.

[0028] The rotating disk 2208 is fixedly connected to the end of the screw 2207 away from the platform door body 5. The rotating disk 2208 is made of rubber. The fixed shell 2206 has a hole 9 on the side near the rotating disk 2208. The hole 9 is set in a number and is evenly distributed in a ring at equal angles. The surface of the rotating disk 2208 has holes that fit into the hole 9. A pin 8 is provided inside the hole. A spring is sleeved on the outside of the limiting post 2205. The two ends of the spring are fixedly connected to the side of the fixed plate 2201 away from each other and the surface of the sliding groove 6, respectively.

[0029] Working principle: During use, if disassembly is required, first pull the pin 8 out from the inside of the socket 9. Then, rotate the rotating disk 2208 clockwise, which in turn drives the lead screw 2207 to rotate. When the lead screw 2207 rotates, it drives the sliding plate 2204 closer to the platform door body 5. Simultaneously, the connecting plate 2203 is driven by the sliding plate 2204 to move synchronously. When the connecting plate 2203 moves, it drives the driving block 2202 to gradually approach the locking block 7. During the movement of the driving block 2202, the angle of the driving block 2202 will contact the angle of the fixed plate 2201. As the angles gradually move away from each other, they will cause the fixed plate 2201 to move away from each other. Since the fixed plate 2201 is fixed to the locking block 7, the fixed plate 2201 drives the locking block 7 to move away from the fixed plate 7. As block 7 gradually disengages from the inner side of the mounting groove 4, the platform door body 5 is moved upward, causing the mounting base 3 to disengage from the inner side of the mounting groove 2, thus completing the disassembly. If installation is required, the platform door body 5 is gradually lowered from above the mounting groove 2 until the mounting base 3 is in complete contact with the surface of the mounting groove 2. After the mounting base 3 is completely lowered, the rotating disk 2208 is reversed, causing the drive block 2202 to disengage from the contact of the fixing plate 2201. At this time, the talk timer on the outside of the limit post 2205 will push the fixing plate 2201 closer together, thereby resetting the locking block 7, so that the locking block 7 re-contacts the mounting groove 4, thus completing the installation. Then, the pin 8 is reinserted into the inner side of the hole and contacts the insertion hole 9, thereby preventing the rotating disk 2208 from rotating.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
