Description

Technical Field

[0001] This invention relates to the field of transportation technology, specifically a small partition for use in vehicle compartments. Background Technology

[0002] A partition wall typically refers to a simple wall used to separate or isolate a room or space. These simple walls come in various forms, commonly using panel structures or railing structures. For example, Chinese patent document CN214492906U discloses a partition wall and a rail vehicle incorporating it. This partition wall is a panel structure; once separated, the space is relatively fixed and cannot be adjusted. Any adjustments require complete removal. Chinese patent document CN213322994U discloses a railing structure and a vehicle. This railing structure is used for isolation in buses, creating a space for disabled users. This railing structure allows for flexible switching between working and storage positions, reducing the space occupied when not in use and solving the problem of large space occupation when not in use in existing railing structures. Chinese patent document CN217917926U discloses a folding handrail for disabled persons and a railcar for rail vehicles. This structure also belongs to the category of guardrail structures for partitioning. The space of this structure can be adjusted as needed, but its adjustment is relatively cumbersome. The second position locking mechanism is located low and is easy to adjust. The latter two guardrail structures mentioned above are both self-adjustable, but they only have one level of adjustment (adjusting between the unfolded and retracted states), and there is a certain risk of accidental operation. If the guardrail is accidentally unfolded or retracted during vehicle operation, it can easily cause personal injury. Summary of the Invention

[0003] The purpose of this invention is to provide a simple, easy-to-adjust, and reliable small partition wall for use in vehicle compartments.

[0004] The basic technical solution for achieving the objective of this invention is: a small partition wall with a turning angle, comprising a guardrail assembly, the guardrail assembly including a primary guardrail, the primary guardrail being rotatably mounted on the side wall of the carriage. Its structural features include: further comprising a rotation adjustment assembly and a ground lock assembly. The rotation adjustment assembly includes a column and a column locking mechanism. The column includes a lower mounting base.

[0005] The column locking mechanism includes a column lock head, a column lock shaft, a column lock tongue, and a lock tongue seat. The upper end of the column lock head has a first square transmission part. The column lock shaft is slidably mounted on the column. The column lock head is fixedly mounted on the upper end of the column lock shaft. The column lock tongue is fixedly mounted on the lower end of the column lock shaft. The lower end of the column lock tongue has outwardly protruding lower locking protrusions on its radially opposite sides. The upper end of the column lock tongue has outwardly protruding upper limit protrusions on its radially opposite sides, and the upper limit protrusions and lower locking protrusions correspond axially. The lock tongue seat is screwed and fixedly mounted on the lower end of the lower mounting base. The lock tongue seat has lock tongue guide grooves running through it on its radially opposite sides, and the lock tongue guide grooves cooperate with the upper limit protrusions and lower locking protrusions on the column lock tongue. The column lock tongue is slidably mounted in the lock tongue seat.

[0006] The number of ground lock assemblies corresponds to the number of states required for the primary guardrail. Each ground lock assembly includes a ground lock mounting base, which secures the assembly to the vehicle floor. The mounting base has a lock cylinder insertion hole in the center, and inwardly protruding locking blocks on opposite radial sides above the insertion hole. The mounting base and the lock cylinder seat are clamped and secured by the lower locking protrusion and upper locking protrusion of the bolt.

[0007] Furthermore, for ease of assembly, the post also includes an upper mounting base, a middle mounting base, an upper connecting pipe, a lower connecting pipe, an upper end cap, and a lower connecting base. The upper and lower ends of the rear of the primary guardrail are respectively fixedly installed in the upper and lower mounting bases. The upper mounting base is coaxially fixedly connected to the upper connecting pipe via the upper connecting base. The upper connecting pipe is fixedly installed on the upper end of the middle mounting base. The lower end of the middle mounting base is fixedly connected to the lower connecting pipe. The upper and lower connecting pipes are coaxially arranged. The lower connecting pipe is coaxially fixedly connected to the lower mounting base via the lower connecting base. The upper end cap is fixedly installed on the upper end of the upper mounting base.

[0008] The column locking shaft passes through the upper end cover, upper mounting base, upper connecting pipe, middle mounting base, lower connecting pipe and lower mounting base in sequence from top to bottom, and the column locking shaft is axially slidably connected to the upper mounting base, middle mounting base and lower mounting base.

[0009] Furthermore, to adapt to the installation environment, a partition wall is also included. This partition wall is fixedly installed on the side wall of the carriage, perpendicular to the carriage floor. The front end of the primary guardrail is rotatably mounted on the right end of the partition wall.

[0010] Furthermore, to prevent the lock cylinder socket of unused lock components from being blocked by debris, the lock components also include a lock base cover, a dust cover, and a lock compression spring. The lock cylinder socket has downward-through guide grooves on both radially opposite sides of its wall.

[0011] The bottom cover of the floor lock is fixedly mounted on the lower side of the floor lock mounting base. The dust cover is a single piece, consisting of a dust cover section and a spring connecting post from top to bottom. The shape of the dust cover section corresponds to the shape of the upper part of the lock cylinder insertion hole of the floor lock mounting base. Guide sliders corresponding to the guide grooves of the floor lock mounting base are provided on opposite radial sides of the dust cover section. The dust cover is slidably positioned in the guide groove of the floor lock mounting base by its guide sliders, with the corresponding part of the dust cover section located in the upper part of the lock cylinder insertion hole, sealing the upper opening of the lock cylinder insertion hole. The upper part of the floor lock compression spring is fitted onto the spring connecting post of the dust cover, and the lower end abuts against the bottom cover of the floor lock, thus being in a compressed state.

[0012] Furthermore, to prevent overcrowding and better protect the area for disabled users, the guardrail assembly also includes a secondary guardrail. The rotation adjustment assembly also includes a secondary locking mechanism.

[0013] The column also includes an upper mounting base and a lower mounting base.

[0014] The secondary guardrail is rotatably mounted on the posts. A corresponding rotating connecting seat is fixedly installed at both the upper and lower ends of the front of the secondary guardrail. The upper rotating connecting seat is rotatably mounted on the upper mounting base of the post. The lower rotating connecting seat is rotatably mounted on the lower mounting base. The rotating connecting seats are also equipped with locking holes. These locking holes cooperate with the secondary locking mechanism to lock the secondary guardrail in the corresponding positions.

[0015] Furthermore, to ensure smoother rotation and better positioning, the post also includes an upper connecting seat. The upper rotating connecting seat of the secondary guardrail is also equipped with a guide limiting post, which protrudes downwards from the rotating connecting seat. An arc-shaped limiting groove is provided on the upper side of the upper connecting seat, and the corresponding part of the guide limiting post is slidably positioned within the arc-shaped limiting groove.

[0016] Furthermore, for secure fixing: the secondary locking mechanism includes a secondary lock head seat, a secondary lock head, a drive turntable, a secondary lock tongue linkage, a secondary lock tongue, and a secondary lock tongue compression spring. There are two secondary lock tongue compression springs.

[0017] The column also includes an upper connecting seat and a lower connecting seat.

[0018] The secondary lock head seat is fixedly mounted radially along the column on the left side of the central mounting base. The secondary lock head is rotatably mounted on the secondary lock head seat. The rotation axis of the secondary lock head is set radially along the column. The drive turntable is fixedly mounted on the right end of the secondary lock head, located within the secondary lock head seat.

[0019] There are two secondary locking tongue linkages, one on the upper side and one on the lower side of the drive turntable. The drive turntable drives the two secondary locking tongue linkages to move up and down. There are two secondary locking tongues, each fixedly mounted on a corresponding secondary locking tongue linkage. The upper secondary locking tongue slides within the upper connecting seat, and a secondary locking tongue compression spring is fitted onto the upper secondary locking tongue linkage, positioned between the secondary locking tongue and the corresponding part of the upper connecting seat, and is in a compressed state. The secondary locking tongue engages with the corresponding locking hole of the upper rotating connecting seat, thereby locking the secondary guardrail in the corresponding position.

[0020] The lower secondary locking tongue is slidably mounted in the lower connecting seat. Another secondary locking tongue compression spring is sleeved on the lower secondary locking tongue connecting rod and is located between the secondary locking tongue and the corresponding part of the lower connecting seat, and is in a compressed state. The secondary locking tongue and the corresponding locking hole of the lower rotating connecting seat form a plug-in engagement, thereby locking the secondary guardrail in the corresponding position.

[0021] The present invention has the following beneficial effects: (1) The small partition structure of the present invention is simple. It can be unlocked or locked by the key (square key with four inner corners) commonly used in subways, trains, bullet trains and high-speed trains in the prior art. When unlocking the column, it is only necessary to stand and operate. It is not only convenient to adjust, but also cannot be operated by ordinary passengers, which greatly improves the reliability and safety of use. (2) The small partition of the present invention is flexible and diverse. The number of ground lock components can be set according to the number of states required by the first-level guardrail, so that the space can be adjusted in a variety of ways to adapt, which greatly improves the adaptability and application scenario range. (3) The small partition of the present invention also includes the installation partition plate. Since there is a certain curvature between the side wall of the carriage and the floor of the carriage, the installation partition plate can ensure that the rotation axis of the first-level guardrail is located on the floor of the carriage and is perpendicular to the floor of the carriage. (4) The ground lock components of the small partition of the present invention are also equipped with dust covers, which can prevent the lock cylinder holes of unused ground lock components from being blocked by garbage. (5) In order to better protect the use area of ​​disabled persons and avoid overcrowding and disabled persons being squeezed behind the first-level guardrail, the small partition of the present invention is also equipped with a second-level guardrail (see Figure 14 (6) The secondary locking mechanism of the small partition wall of the present invention is unlocked or locked using a key (a square key with four inner corners) commonly used in subways, trains, bullet trains and high-speed trains in the prior art. Ordinary passengers cannot operate it, which greatly improves the reliability and safety of use. The secondary locking mechanism can be set according to the usage requirements of the secondary guardrail, with strong adaptability and wide application range. (7) The secondary locking mechanism of the small partition wall of the present invention is provided with two secondary locking tongues. The two secondary locking tongues lock the upper and lower rotating connecting seats at the same time, and the locking is firm. The two locking tongues are driven by the secondary lock head at the same time, and the unlocking is quick. Attached Figure Description

[0048] (Example 1)

[0049] See Figures 1 to 17 The partition wall of the present invention includes a guardrail assembly 1, a rotation adjustment assembly 2, a ground lock assembly 3, and a mounting partition wall 4. The mounting partition wall 4 is fixedly installed on the side wall 10-1 of the carriage and is perpendicular to the carriage floor 10-2.

[0050] See Figures 1 to 5 and Figure 8 The guardrail assembly 1 includes a primary guardrail 11 and a secondary guardrail 12. The front end of the primary guardrail 11 is rotatably mounted on the right end of the mounting partition panel 4. A rotation adjustment assembly 2 is fixedly mounted on the rear end of the primary guardrail 11, and the secondary guardrail 12 is rotatably mounted on the rotation adjustment assembly 2. The secondary guardrail 12 is locked in a retracted or extended state by the rotation adjustment assembly 2. A corresponding rotating connecting seat 12-1 is fixedly mounted on the upper and lower ends of the front part of the secondary guardrail 12. The rotating connecting seat 12-1 has a guardrail pivot through hole 12-11 in the middle, which runs through it from top to bottom. The rotating connecting seat 12-1 also has several locking holes. The number of locking holes is determined according to the number of positions that the secondary guardrail 12 needs to be adjusted to, and the angle between each locking hole is determined according to the angle between the positions that the secondary guardrail 12 needs to be adjusted to. The locking holes are used to cooperate with the secondary locking mechanism 23 to lock the secondary guardrail 12 in the corresponding position. In this embodiment, the secondary guardrail 12 needs to be adjusted to two positions: a retracted position and an extended position. Therefore, the rotating connecting seat 12-1 in this embodiment has two locking holes, referred to as the first locking hole 12-12 and the second locking hole 12-13. Both the first locking hole 12-12 and the second locking hole 12-13 penetrate the rotating connecting seat 12-1 from top to bottom and are connected to the guardrail pivot through hole 12-11. The angle between the adjustable positions of the secondary guardrail 12 in this embodiment is 160 degrees, thus the interval angle between the first locking hole 12-12 and the second locking hole 12-13 is 160 degrees. The upper rotating connecting seat 12-1 also has a guide limiting post 12-14, which protrudes downwards from the rotating connecting seat 12-1.

[0054] See Figures 8 to 13 The column locking mechanism 22 includes a column lock head 22-1, a column lock shaft 22-2, a column lock tongue 22-3, a lock tongue seat 22-4, and a lock head cover 22-5. The upper end of the column lock head 22-1 is provided with a first square transmission part 22-11. The first square transmission part 22-11 cooperates with an inner square key, which is a tool key commonly used in subways, trains, high-speed trains, and bullet trains in the prior art. The column lock shaft 22-2 passes through the upper end cover 21-6, the upper mounting seat 21-1, the upper connecting pipe 21-4, the middle mounting seat 21-2, the lower connecting pipe 21-5, and the lower mounting seat 21-3 sequentially from top to bottom, and the column lock shaft 22-2 is axially slidably connected to the upper mounting seat 21-1, the middle mounting seat 21-2, and the lower mounting seat 21-3. The column lock head 22-1 is fixedly mounted on the upper end of the column lock shaft 22-2. A lock shaft return spring 22-21 is fitted onto the upper end of the column lock shaft 22-2. The lock shaft return spring 22-21 is located between the column lock head 22-1 and the upper end cover 21-6 and is in a compressed state. The lock head cover 22-5 is screwed and fixedly mounted on the upper end cover 21-6, covering the corresponding upper parts of the column lock head 22-1 and the column lock shaft 22-2. The upper part of the lock head cover 22-5 has a through hole that connects the inside and outside. The inner square key passes through the through hole on the lock head cover 22-5 and is inserted into the first square transmission part 22-11 of the column lock head 22-1, forming a transmission connection. When the inner square key is rotated, the inner square key drives the column lock head 22-1 to rotate, which in turn drives the column lock shaft 22-2 to rotate through the column lock head 22-1.

[0055] The pillar locking tongue 22-3 is fixedly mounted on the lower end of the pillar locking shaft 22-2. The lower end of the pillar locking tongue 22-3 has outwardly protruding lower locking protrusions 22-31 on both radially opposite sides. The upper end of the pillar locking tongue 22-3 has outwardly protruding upper limit protrusions 22-32 on both radially opposite sides. The upper limit protrusions 22-32 and the lower locking protrusions 22-31 are axially aligned.

[0056] The latch seat 22-4 is screwed and fixedly mounted on the lower end of the lower mounting base 21-3. The latch seat 22-4 has latch guide grooves 22-41 running through it on both radially opposite sides. The latch guide grooves 22-41 cooperate with the upper limit protrusion 22-32 and the lower locking protrusion 22-31 on the column latch 22-3. The column latch 22-3 is slidably mounted within the latch seat 22-4.

[0057] See Figures 8 to 13 The secondary locking mechanism 23 includes a secondary lock head seat 23-1, a secondary lock head 23-2, a drive turntable 23-3, a secondary lock tongue connecting rod 23-4, a secondary lock tongue 23-5, and a secondary lock tongue compression spring 23-6. There are two secondary lock tongue compression springs 23-6.

[0058] The secondary lock head seat 23-1 is fixedly mounted radially along the column 21 on the left side of the central mounting base 21-2. The secondary lock head 23-2 is rotatably mounted on the secondary lock head seat 23-1 and is axially limited and fixed on the secondary lock head seat 23-1 by the secondary lock head retaining spring 23-22. The rotation axis of the secondary lock head 23-2 is arranged radially along the column 21. The drive turntable 23-3 is fixedly mounted on the right end of the secondary lock head 23-2, located in the secondary lock head seat 23-1. The left end of the secondary lock head 23-2 is provided with a second square transmission part 23-21, which cooperates with an inner square key, which is a tool key commonly used in subways, trains, high-speed trains and bullet trains in the prior art. Two locking tongue drive grooves 23-31 are symmetrically arranged along the upper edge of the drive turntable 23-3. The locking tongue drive groove 23-31 is provided with a guide surface 23-311. One end of the guide surface 23-311 is away from the rotation axis of the drive turntable 23-3, and the other end is close to the rotation axis of the drive turntable 23-3.

[0059] There are two secondary locking tongue connecting rods 23-4, which are respectively located on the upper and lower sides of the drive turntable 23-3. The two secondary locking tongue connecting rods 23-4 are connected to the drive turntable 23-3 by corresponding pins, the corresponding parts of which are located in the locking tongue drive groove 23-31. When the drive turntable 23-3 rotates, the secondary locking tongue connecting rods 23-4 move towards or away from the rotation axis of the drive turntable 23-3. There are two secondary locking tongues 23-5, which are respectively fixedly mounted on a corresponding secondary locking tongue connecting rod 23-4. The upper secondary locking tongue 23-5 is slidably disposed in the upper connecting seat 21-7. A secondary locking tongue compression spring 23-6 is sleeved on the upper secondary locking tongue connecting rod 23-4 and is located between the corresponding part of the secondary locking tongue 23-5 and the upper connecting seat 21-7. It is in a compressed state, thereby generating an upward restoring force, which pushes the upper secondary locking tongue 23-5 upward, so that the secondary locking tongue 23-5 is inserted into the first locking hole 12-12 or the second locking hole 12-13 of the upper rotating connecting seat 12-1, forming a plug-in fit, thereby locking the secondary guardrail 12 in the corresponding position.

[0060] The secondary locking tongue 23-5 located below is slidably disposed in the lower connecting seat 21-8. Another secondary locking tongue compression spring 23-6 is sleeved on the secondary locking tongue connecting rod 23-4 located below, and is located between the corresponding part of the secondary locking tongue 23-5 and the lower connecting seat 21-8. It is in a compressed state, thereby generating a downward restoring force, pushing the secondary locking tongue 23-5 below downward, so that the secondary locking tongue 23-5 is inserted into the first locking hole 12-12 or the second locking hole 12-13 of the rotating connecting seat 12-1 located below, forming a plug-in fit, thereby locking the position of the secondary guardrail 12 in the corresponding position.

[0061] See Figure 6 , Figure 7 , Figure 15 and Figure 16 The number of ground lock components 3 corresponds to the number of states required for the primary guardrail 11. In this embodiment, the primary guardrail 11 has two states: a retracted state and an unfolded state. Therefore, there are two sets of ground lock components 3 in this embodiment. The ground lock component 3 includes a ground lock mounting base 31, a ground lock bottom cover 32, a dust cover 33, and a ground lock compression spring 34. The ground lock component 3 is fixedly mounted on the vehicle floor 10-2 by its ground lock mounting base 31.

[0062] The lock mounting base 31 has a lock cylinder insertion hole 31-1 in the middle. On the upper part of the lock cylinder insertion hole 31-1, on opposite radially opposite sides, are inwardly protruding latching blocks 31-2. The upper edge of the lock cylinder insertion hole 31-1 has a guide slope 31-11. On the wall of the lock cylinder insertion hole 31-1, on opposite radially opposite sides, are downwardly penetrating guide grooves 31-3. The guide grooves 31-3 are located on opposite sides in a direction perpendicular to the protruding direction of the latching blocks 31-2 (see...). Figure 15 ).

[0063] The bottom cover 32 of the floor lock is fixedly mounted on the lower side of the floor lock mounting base 31, closing the lower end of the lock cylinder insertion hole 31-1 of the floor lock mounting base 31 from below. The dust cover 33 is an integral piece, and in this embodiment, the dust cover 33 is an integral piece made of stainless steel. The dust cover 33 has a dust cover part 33-1 and a spring connecting post 33-2 arranged sequentially from top to bottom. The shape of the dust cover part 33-1 corresponds to the shape of the upper part of the lock cylinder insertion hole 31-1 of the floor lock mounting base 31. The dust cover part 33-1 has guide sliders 33-3 on both radially opposite sides, corresponding to the guide grooves 31-3 of the floor lock mounting base 31. The dust cover 33 is slidably mounted in the guide groove 31-3 of the floor lock mounting base 31 by its guide slider 33-3. The corresponding part of its dust cover portion 33-1 is located in the upper part of the lock cylinder insertion hole 31-1, sealing the upper opening of the lock cylinder insertion hole 31-1, thereby preventing garbage on the vehicle floor 10-2 from falling into the lock cylinder insertion hole 31-1. The upper part of the floor lock compression spring 34 is sleeved on the spring connecting post 33-2 of the dust cover 33, and the lower end abuts against the bottom cover 32 of the floor lock, and is in a compressed state, thereby pushing the dust cover 33 upward, so that it can effectively seal the upper opening of the lock cylinder insertion hole 31-1.

[0064] See Figure 6 and Figure 15 The angle formed by the protruding direction of the locking block 31-2 of the ground lock component 3 in the unfolded state and the protruding direction of the locking block 31-2 of the ground lock component 3 in the retracted state corresponds to the angle formed by the primary guardrail 11 from the retracted state to the unfolded state. In this embodiment, the angle formed by the primary guardrail 11 from the retracted state to the unfolded state is 90 degrees, that is, the angle formed by the protruding direction of the locking block 31-2 of the ground lock component 3 in the unfolded state and the protruding direction of the locking block 31-2 of the ground lock component 3 in the retracted state is 90 degrees. Therefore, when the rotation adjustment component 2 changes 90 degrees from the retracted state to the unfolded state along with the primary guardrail 11, the column locking tongue 22-3 of the column locking mechanism 22 can cooperate with the corresponding ground lock component 3 to lock and fix the connection.

[0065] See Figure 1 , Figure 7 and Figure 13 When the small partition wall of the present invention is in the storage state against the side wall 10-1 of the carriage (see...) Figure 1At this time, the lower end of the column locking mechanism 22 of the rotating adjustment component 2 is inserted into the lock cylinder insertion hole 31-1 of the corresponding ground lock component 3, and the lower locking protrusion 22-31 of the column locking mechanism 22-3 is located below the corresponding snap-fit ​​block 31-2; the upper limit protrusion 22-32 is located on the upper side of the locking tongue seat 22-4 (see...). Figure 13 The locking lug 22-3 is at a 90-degree angle to the guide groove 22-41, thus the lower locking protrusion 22-31 and the upper locking protrusion 22-32 of the column locking lug 22-3 clamp and fix the ground lock mounting base 31 and the locking lug base 22-4. That is, the column locking lug 22-3 is locked on the ground lock assembly 3, and the column 21 is locked and fixed on the carriage floor 10-2. The secondary guardrail 12 and the primary guardrail 11 are in the same plane. At this time, the secondary locking lug 23-5 of the secondary locking mechanism 23 is inserted into the first locking hole 12-12 of the corresponding rotating connecting seat 12-1, so that the secondary guardrail 12 is in a locked state and cannot be rotated.

[0066] See Figure 14 When it is necessary to change the storage state to the unfolded state for use by disabled persons, first insert the inner square key through the through hole on the lock head cover 22-5 and then into the first square transmission part 22-11 of the pillar lock head 22-1 to form a transmission connection. Then, rotate the inner square key 90 degrees, causing the pillar lock shaft 22-2 to drive the pillar lock tongue 22-3 to rotate 90 degrees. When the lower locking protrusion 22-31 of the pillar lock tongue 22-3 rotates out from under the locking block 31-2 and disengages from the locking block 31-2, under the action of the floor lock compression spring 34, the floor lock compression spring 34 pushes the guide slider 33-3 upward, thereby pushing the pillar lock tongue 22-3 upward. At the same time, the lock shaft return spring also pushes the pillar lock head 22-1 upward, thereby causing the pillar lock shaft 22-2 to move upward through the pillar lock head 22-1. When the movable pillar latch 22-3 is completely disengaged from the ground lock assembly 3, the pillar 21 is in the unlocked state, and the primary guardrail 11 can be rotated. When the pillar 21 is rotated onto the ground lock assembly 3 in front, the pillar lock head 22-1 is pressed down by the inner four-corner square key, and the pillar latch 22-3 is inserted downward into the lock cylinder insertion hole 31-1 of the ground lock assembly 3 through the pillar lock shaft 22-2. At the same time, the dust cover 33 is pressed down. When the lower locking protrusion 22-31 of the pillar latch 22-3 is lower than the locking block 31-2, the inner four-corner square key is rotated 90 degrees in the opposite direction, so that the lower locking protrusion 22-31 of the pillar latch 22-3 is rotated to the bottom of the locking block 31-2, thereby locking the pillar 21 onto the ground lock assembly 3. At this time, the position of the primary guardrail 11 is adjusted and is in a locked and fixed state.

[0067] Next, insert the inner square key into the second square transmission part 23-21 of the secondary lock head 23-2 of the secondary locking mechanism 23 to form a transmission connection. Then, rotate the inner square key 90 degrees, driving the turntable 23-3 to rotate 90 degrees. At the same time, the guide surface 23-311 pulls the secondary lock tongue connecting rod 23-4 towards the rotation axis, thereby causing the secondary lock tongue 23-5 to exit downwards from the first locking hole 12-12 of the rotating connecting seat 12-1. At this time, the secondary guardrail 12 is in the unlocked state. When the secondary guardrail 12 is released, the inner four-corner square key is released. When the secondary locking tongue 23-5 rotates to correspond with the second locking hole 12-13 of the rotating connecting seat 12-1, the secondary locking tongue 23-5 is pushed into the second locking hole 12-13 under the action of the secondary locking tongue compression spring 23-6. At the same time, the inner four-corner square key is rotated 90 degrees to reset. At this time, the inner four-corner square key is removed, and the secondary guardrail 12 is in the unfolded and locked state. The secondary guardrail 12 can prevent other passengers from approaching the disabled and play a corresponding protective role.

[0068] (Example 2)

[0069] The rest of this embodiment is the same as that of embodiment 1. The difference is that the structure of each ground lock component 3 is the same. The angle between the ground lock component 3 in the unfolded state and the ground lock component 3 in the retracted state during installation corresponds to the angle between the first-level guardrail 11 from the retracted state to the unfolded state. That is, the ground lock component 3 in the unfolded state and the ground lock component 3 in the retracted state are perpendicular to each other.
