Description

Technical Field

[0001] This utility model relates to the field of high-speed rail seat technology, specifically a high-speed rail seat that is easy to disassemble, assemble, and adjust. Background Technology

[0002] With the rapid development of the high-speed rail industry, my country has ranked first in the world in terms of high-speed rail operating mileage for many consecutive years, and the annual passenger volume continues to climb. As high-speed rail travel gradually becomes the preferred mode of long-distance travel for the public, passengers have increasingly higher demands for their travel experience. While the existing high-speed rail seats can basically meet daily needs, there are still some shortcomings that need to be improved.

[0003] Currently, to meet passengers' needs for dining and working during their journeys, most high-speed rail seats are equipped with rear-mounted folding tables. However, this traditional design hinges the table to the back of the front seat. While it provides temporary support when unfolded, it reveals two major drawbacks in actual operation: First, it creates significant space conflicts. When passengers need to frequently get up to move around (such as to the dining car or restroom), they must manually fold up the tables one by one, a cumbersome process that is prone to accidental collisions with pedestrians' legs. Second, it lacks a secure mounting function. Existing tables are mostly smooth surfaces with only simple cup holders. When placing items such as water cups or tablets, the inertia generated by the train's acceleration, deceleration, or turns can easily cause these items to slip off, resulting in not only property damage but also potential safety hazards as items roll into the aisle. Therefore, we propose a high-speed rail seat that is easy to assemble, disassemble, and adjust to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed rail seat that is easy to disassemble, assemble, and adjust, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed rail seat that is easy to disassemble and adjust, comprising a high-speed rail seat and a base installed at the bottom of the high-speed rail seat. A rotating seat is installed at the center of the front end of the high-speed rail seat. A rotating shaft is rotatably connected inside the rotating seat. A connecting rod is fixed to the outer wall of the rotating shaft. A table is installed at the end of the connecting rod away from the rotating shaft. A fixed seat is fixed to the right side of the top of the table. A guide groove is opened at the lower left end of the table. A through groove is opened at the top of the guide groove. A guide block is slidably connected inside the guide groove. A movable clamp is fixed to the top of the guide block. A first return spring is provided on the left side of the guide block. A rotation positioning component is provided on the left side of the rotating seat.

[0006] As a further preferred embodiment of this technical solution, the rotary positioning assembly includes two sets of guide rods fixed to the outer wall of the left side of the rotating seat. A retaining plate is fixed to the left end of each set of guide rods. A sleeve is slidably connected to the outside of each set of guide rods. Two sets of locking rods are installed on the outside of the sleeves at one end facing the connecting rod. A locking hole is opened at the end of the connecting rod facing the locking rod. The end of the locking rod can be inserted into the locking hole. A pull handle is installed in the middle of the sleeve. A second return spring is wound around the outside of each set of guide rods.

[0007] As a further preferred embodiment of this technical solution, a partition is fixed to the outer wall of the left side of the movable clamp, the size of the partition is larger than the size of the through groove, and an opening corresponding to the partition is opened on the side end of the table.

[0008] As a further preferred embodiment of this technical solution, the two ends of the first reset spring are respectively connected to the outer wall of the guide block and the inner wall of the guide groove, and the guide block is elastically connected to the inner wall of the guide groove through the first reset spring.

[0009] As a further preferred embodiment of this technical solution, rubber pads are glued to the outer walls of opposite ends of the fixed seat and the movable clamp.

[0010] As a further preferred embodiment of this technical solution, the top of the movable clamp is provided with a buckle groove, and the inside of the buckle groove is provided with anti-slip texture.

[0011] This utility model provides a high-speed rail seat that is easy to disassemble, assemble, and adjust, and has the following advantages:

[0012] 1. This utility model features a rotatable table installed in the middle of a high-speed rail seat. When the user is seated, the table can be rotated, causing the connecting rod and pivot to rotate within the rotating seat. This allows the lower part of the table between the legs to flip upwards, eliminating the need to fix it to the seat in front and bringing the table closer to the user for easier use. Furthermore, the table is equipped with a movable clamp, allowing for quick securing of items of different sizes and easy disassembly, effectively preventing items from slipping and improving safety.

[0013] 2. This utility model has two sets of locking rods that can move back and forth installed on the side of the rotating seat. The second return springs outside the two sets of guide rods release their elastic force to push the sleeve towards the rotating seat, so that the sleeve drives the locking rod to insert into the lock hole outside the connecting rod, quickly completing the locking of the connecting rod, thereby ensuring the stability of the table when in use.

Detailed Implementation

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0022] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0023] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a high-speed rail seat that is easy to assemble, disassemble, and adjust includes a high-speed rail seat 1 and a base 2 installed at the bottom of the high-speed rail seat 1. A rotating seat 3 is installed at the middle of the front end of the high-speed rail seat 1. A rotating shaft 4 is rotatably connected inside the rotating seat 3. A connecting rod 5 is fixed to the outer wall of the rotating shaft 4. A table 6 is installed at the end of the connecting rod 5 away from the rotating shaft 4. A fixed seat 7 is fixed to the right side of the top of the table 6. A guide groove 8 is opened at the lower left side of the table 6. A through groove 11 is opened at the top of the guide groove 8. A guide block 9 is slidably connected inside the guide groove 8. A movable clamp 10 is fixed to the top of the guide block 9. A first reset spring 13 is provided on the left side of the guide block 9. A rotation positioning component is provided on the left side of the rotating seat 3.

[0024] By installing a rotatable table 6 in the middle of the high-speed rail seat 1, the user can rotate the table 6 while sitting on the seat. This allows the table 6 to drive the connecting rod 5 and the rotating shaft 4 to rotate within the rotating seat 3, causing the lower part of the legs of the table 6 to flip upwards. This eliminates the need for the table to be fixed to the seat in front, bringing it closer to the user for easier use. Furthermore, a movable clamp 10 is installed on the table 6. The movable clamp 10 can be pulled open, moving it away from the fixed seat 7, and allowing the movable clamp 10 to... The guide block 9 slides along the guide groove 8, causing the first return spring 13 to be compressed and stored by the guide block 9. Then, the item to be fixed can be placed between the movable clamp 10 and the fixed seat 7. Then, the tension on the movable clamp 10 is released, allowing the first return spring 13 to release its elasticity and push the movable clamp 10 toward the fixed seat 7. This allows the movable clamp 10 and the fixed seat 7 to quickly fix items of different sizes and also facilitates quick disassembly of the items, thereby effectively preventing the items from slipping and improving safety.

[0025] In other embodiments, the rotary positioning assembly includes two sets of guide rods 15 fixed to the left outer wall of the rotating seat 3, a clamping plate 16 fixed to the left end of the two sets of guide rods 15, a sleeve 17 slidably connected to the outside of the two sets of guide rods 15, two sets of locking rods 18 installed on the outside of the sleeve 17 facing the end of the connecting rod 5, a locking hole 19 opened on the end of the connecting rod 5 facing the locking rod 18, the end of the locking rod 18 can be inserted into the locking hole 19, a pull handle 20 is installed in the middle of the sleeve 17, and a second return spring 21 is wound around the outside of both sets of guide rods 15;

[0026] By installing two sets of locking rods 18 that can move back and forth on the side of the rotating seat 3, when it is necessary to rotate the connecting rod 5, the handle 20 can be pulled first, so that the sleeve 17 drives the two sets of locking rods 18 to move along the surface of the two sets of guide rods 15, and the sleeve 17 squeezes the second return spring 21. When the locking rod 18 leaves the lock hole 19 on the connecting rod 5, the table 6 can be turned, so that the connecting rod 5 drives the rotating shaft 4 to rotate 180 degrees along the inside of the rotating seat 3. Then the pulling force on the handle 20 can be contacted, so that the second return spring 21 outside the two sets of guide rods 15 releases its elasticity and pushes the sleeve 17 toward the rotating seat 3, so that the sleeve 17 drives the locking rod 18 to insert into the lock hole 19 outside the connecting rod 5, quickly completing the locking of the connecting rod 5, thereby ensuring the stability of the table 6 during use.

[0027] In other embodiments, a partition 12 is fixed to the outer left side of the movable clamp 10. The size of the partition 12 is larger than the size of the through groove 11. An opening 14 corresponding to the partition 12 is opened on the side end of the table 6.

[0028] This design allows the partition 12 to cover the outside of the channel 11, thereby preventing external objects from entering the channel 11 when the tabletop 6 is not in use.

[0029] In other embodiments, the two ends of the through groove 11 are respectively connected to the outer wall of the guide block 9 and the inner wall of the guide groove 8, and the guide block 9 forms an elastic connection with the inner wall of the guide groove 8 through the through groove 11;

[0030] This design allows the through groove 11 to continuously apply the elastic force of the slide groove to the fixed seat 7 to the guide block 9, enabling the movable clamp 10 to quickly and effectively clamp and fix the item.

[0031] In other embodiments, rubber pads are glued to the outer walls of opposite ends of the fixed base 7 and the movable clamp 10;

[0032] This design effectively prevents the fixed seat 7 and the movable clamp 10 from causing wear and tear on the surface of items placed by passengers, thus preventing damage to the items.

[0033] In other embodiments, the top of the movable clamp 10 is provided with a buckle groove, and the inside of the buckle groove is provided with anti-slip texture;

[0034] This design increases the friction between the hand and the slot on the movable clamp 10, making it easier to fasten the movable clamp 10.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
