[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference Figures 1 to 11 In certain embodiments of the present invention, a guardrail door capable of adjusting the overall width of a door body assembly is sometimes referred to as a "guardrail door" for ease of description. A guardrail door capable of adjusting the overall width of a door body assembly includes a door body assembly 100 and a door frame assembly. The door body assembly 100 includes at least two door bodies 110. All door bodies 110 are movably connected in sequence. At least one set of connecting and locking devices 200 is provided between two adjacent door bodies 110. The connecting and locking devices 200 can lock or release the two adjacent door bodies 110. When the connecting and locking devices 200 lock the two adjacent door bodies 110, the relative positions of the two adjacent door bodies 110 remain fixed; when the connecting and locking devices 200 release the two adjacent door bodies 110, the two adjacent door bodies 110 can move closer or farther relative to each other.

[0035] For ease of description, in certain embodiments of the present invention, the door main body assembly 100 includes two door main bodies 110, which are movably connected. A group of connecting and locking devices 200 are arranged between the two door main bodies 110. Specifically, the two door main bodies 110 are movably connected together through the connecting and locking devices 200. When the connecting and locking devices 200 connect the two door main bodies 110, the relative positions of the two door main bodies 110 remain unchanged, that is, the overall width of the door main body assembly 100 remains unchanged. When the connecting and locking devices 200 release the two door main bodies 110, the two door main bodies 110 can move closer or farther away from each other. When the two door main bodies 110 can move closer to each other, the overall width of the door main body assembly 100 becomes smaller; when the two door main bodies 110 can move farther away from each other, the overall width of the door main body assembly 100 becomes larger.

[0036] The guardrail door of certain embodiments of the present invention is constructed by connecting a door main body assembly 100 with at least two door main bodies 110 that are movably connected in sequence. At least one set of connecting locking devices 200 is provided between the two adjacent door main bodies 110. The connecting locking devices 200 can lock or release the two adjacent door main bodies 110. When it is necessary to adjust the overall width of the door main body assembly 100, the two adjacent door main bodies 110 can be released by the connecting locking devices 200. The two adjacent door main bodies 110 can be moved closer or farther away from each other, thereby making the overall width of the door main body assembly 100 smaller or larger. When the overall width of the door main body assembly 100 to be adjusted reaches the set value, the two adjacent door main bodies 110 are locked by the connecting locking devices 200 and the relative positions of the two adjacent door main bodies 110 remain unchanged. By adopting the above structure, the overall width of the door main body assembly 100 can be adjusted to adapt to installation positions of different widths, so that the guardrail door of this embodiment has a wider range of application, is simpler and more convenient to install, and better meets the needs of users.

[0037] Reference Figures 2 to 7 In some embodiments of the present invention, each door body 110 has a cross bar 111 arranged along the width direction. The connecting locking device 200 has a movable groove 210 and a locking structure.

[0038] In two adjacent door bodies 110, the connecting and locking device 200 is fixedly mounted on one of the door bodies 110, and the cross bar 111 of the other door body 110 is movably mounted on the movable groove 210, and the cross bar 111 can reciprocate relative to the movable groove 210. That is, when the two door bodies 110 move relative to each other, the door body 110 on which the connecting and locking device 200 is mounted drives the locking device 200 to move relative to the cross bar 111 of the other door body 110, thereby enabling the cross bar 111 to reciprocate relative to the movable groove 210. In this embodiment, the locking structure of the connecting and locking device 200 can lock the cross bar 111 and restrict the movement of the cross bar 111 relative to the movable groove 210, or the locking structure can release the lock between the cross bar 111 and the movable groove 210.

[0039] By adopting the above-mentioned structure, when it is necessary to adjust the overall width of the door main body assembly 100, the lock between the cross bar 111 and the movable groove 210 is released by connecting the locking structure of the locking device 200. At this time, the two adjacent door main bodies 110 can move closer or farther away from each other. When the two adjacent door main bodies 110 move relative to the set position, the locking structure locks the cross bar 111 again and limits the movement of the cross bar 111 relative to the movable groove 210, thereby making the relative position of the two adjacent door main bodies 110 unchanged, so that the overall width of the door main body assembly 100 remains unchanged, thereby achieving the purpose of steplessly adjusting the overall width of the door main body assembly 100.

[0040] Reference Figures 4 to 8 In order to facilitate the production and processing of the connection locking device 200, in certain embodiments of the present invention, the connection locking device 200 includes a locking seat body 201, a movable groove 210 is opened in the locking seat body 201, the movable groove 210 is a through groove that passes through the locking seat body 201, and the locking structure is arranged on the locking seat body 201.

[0041] In two adjacent door bodies 110, the locking seat body 201 is fixedly arranged on one of the door bodies 110, and the cross bar 111 of the other door body 110 is movably installed in the movable groove 210 of the locking seat body 201. The locking structure can lock the cross bar 111 and limit the movement of the cross bar 111 relative to the locking seat body 201, or the locking structure can release the lock between the cross bar 111 and the locking seat body 201 and allow the locking seat body 201 to reciprocate along the cross bar 111. By adopting the above structure, it is convenient to produce and process the connecting locking device 200, and it is also convenient to assemble and install the connecting locking device 200 with the two adjacent door bodies 110, which helps to reduce the assembly difficulty of the door body assembly 100 and improve the assembly efficiency of the door body assembly 100.

[0042] In certain embodiments of the present invention, a notch 202 is formed on the sidewall of the locking seat body 201 and communicates with the movable groove 210. The locking structure of the locking device 200 includes a pressing member 220, which is rotatably mounted on the locking seat body 201 and located on one side of the movable groove 210. The pressing member 220 can rotate relative to the locking seat body 201 toward or away from the notch 202. Specifically, when the pressing member 220 rotates relative to the locking seat body 201 toward the notch 202, the pressing member 220 can cooperate with the locking seat body 201 to clamp the crossbar 111 located within the movable groove 210, thereby fixing the relative position of the crossbar 111 and the locking seat body 201. Alternatively, when the pressing member 220 rotates relative to the locking seat body 201 away from the notch 202 and releases the crossbar 111 located within the movable groove 210, the crossbar 111 can move relative to the locking seat body 201 along the movable groove 210. By adopting the above structure, the locking structure of the connection locking device 200 can more easily lock the cross bar 111 and the seat body 201 or release the lock between the cross bar 111 and the seat body 201, and the operation is simple, convenient and fast.

[0043] In order to further improve the locking force of the locking structure of the connecting locking device 200 on the cross bar 111, in certain embodiments of the present invention, the inner wall of the clamping member 220 facing the notch 202 is provided with a protrusion 230 that can be embedded in the movable groove 210. In this embodiment, the protrusion 230 is a square block fixedly provided on the inner wall of the clamping member 220 facing the notch 202, and the shape of the square block is adapted to the shape of the notch 202. When the connecting locking device 200 needs to lock two adjacent door bodies 110, the pressing member 220 rotates relative to the locking base body 201 to approach and fit into the notch 202. The protrusion 230 on the inner wall of the pressing member 220 facing the notch 202 is embedded in the movable groove 210. Therefore, the protrusion 230 can better squeeze the cross bar 111 located in the movable groove 210. In addition, the pressing member 220 and the locking base body 201 can better clamp the cross bar 111 located in the movable groove 210, so that the two adjacent door bodies 110 cannot move relative to each other, thereby maintaining the overall width of the door body assembly 100. By adopting the above structure, the locking device 200 can achieve a better locking effect in locking the two adjacent door bodies 110.

[0044] Furthermore, in order to prevent the clamping member 220 connected to the locking device 200 from accidentally rotating and releasing the locking force on the cross bar 111, in some embodiments of the present invention, the locking seat body 201 is provided with an anti-rotation structure that limits the rotation of the clamping member 220 relative to the locking seat body 201. By adopting the above-mentioned structure, the pressing piece 220 rotates relative to the locking seat body 201 to approach and fit into the notch 202, and the protrusion 230 of the inner wall of the pressing piece 220 facing the notch 202 is embedded in the movable groove 210 and squeezes the cross bar 111 located inside the movable groove 210. The pressing piece 220 and the locking seat body 201 cooperate to clamp the cross bar 111 located inside the movable groove 210. At this time, the pressing piece 220 can be locked by the anti-rotation structure to prevent the pressing piece 220 from rotating relative to the locking seat body 201 away from the movable groove 210 and releasing the locking force on the cross bar 111, so that the connection locking device 200 of this embodiment can better lock the cross bar 111 and the locking seat body 201 together, so that the overall width of the door main body assembly 100 of the guardrail door of this embodiment is not easy to change during subsequent use.

[0045] Reference Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In order to make the structure of the connection locking device 200 more compact, in certain embodiments of the present invention, the pressing member 220 has a rotating end 221 that is rotatably connected to the locking seat body 201. Specifically, the locking seat body 201 has a rotating seat that is rotatably mounted with the rotating end 221. During installation, the rotating end 221 of the pressing member 220 is rotatably mounted on the rotating seat of the locking seat body 201, and the rotating seat and the rotating end 221 are movably connected together via a rotating shaft. A first hole 222 is defined in the side wall of the pressing member 220 at one end away from the rotating end 221, and a second hole 211 corresponding to the first hole 222 is defined in the side wall of the movable groove 210. The anti-rotation structure includes a columnar member. When the pressing member 220 rotates relative to the locking seat body 201 to approach and fit into the notch 202, the first hole 222 and the second hole 211 are aligned, and the columnar member passes through the second hole 211 and extends into the interior of the first hole 222. By inserting the cylindrical member into the first hole 222 and the second hole 211, the cylindrical member can limit the rotation of the pressing member 220 relative to the locking seat body 201, thereby preventing the pressing member 220 from rotating relative to the locking seat body 201 away from the movable groove 210, so that the pressing member 220 remains in contact with the notch 202. Therefore, the protrusion 230 on the inner wall of the pressing member 220 facing the notch 202 can cooperate with the locking seat body 201 to clamp the crossbar 111 located inside the movable groove 210. By adopting the above structure, the structure of the connecting and locking device 200 can be greatly simplified, making the structure of the connecting and locking device 200 more compact and facilitating the production and processing of the connecting and locking device 200.

[0046] In certain embodiments of the present invention, the pressing member 220 is rotatably connected to the locking base body 201 via a rotating end 221. A first hole 222 is defined in the sidewall of the pressing member 220 at one end away from the rotating end 221. In this embodiment, the first hole 222 is a threaded hole. A second hole 211 corresponding to the first hole 222 is defined in the sidewall of the movable groove 210. The second hole 211 is a through hole with a smooth inner wall. The anti-rotation structure includes a cylindrical member, specifically a bolt. The inner diameter of the second hole 211 matches the outer diameter of the bolt. When the connecting locking device 200 locks the cross bar 111 located inside the movable groove 210, the pressing piece 220 rotates relative to the locking seat body 201 to approach and fit the notch 202, and the first hole 222 and the second hole 211 at the end of the pressing piece 220 are aligned. The bolt passes through the second hole 211 and is screwed into the first hole 222. At this time, the bolt is threadedly connected with the first hole 222, thereby preventing the bolt from accidentally coming out of the first hole 222, so that the bolt can firmly lock the pressing piece 220 to the locking seat body 201, thereby limiting the pressing piece 220 from rotating relative to the locking seat body 201, preventing the pressing piece 220 from rotating relative to the locking seat body 201 away from the movable groove 210, so that the pressing piece 220 remains in a state of fitting the notch 202, so that the protrusion 230 of the inner wall of the side of the pressing piece 220 facing the notch 202 can cooperate with the locking seat body 201 to clamp the cross bar 111 located inside the movable groove 210.

[0047] It should be noted that in the above embodiment, the first hole 222 is a threaded hole, the second hole 211 is a through hole with a smooth inner wall, and the cylindrical member is a bolt. However, in other embodiments of the present invention, the first hole 222, the second hole 211, and the cylindrical member may also adopt other structures. For example, the pressing member 220 is rotatably connected to the locking seat body 201 via the rotating end 221. The side wall of the pressing member 220 away from the rotating end 221 has a first hole 222, which is a through hole with a smooth inner wall. The side wall of the movable groove 210 has a second hole 211, which corresponds to the first hole 222. The second hole 211 is a threaded hole. The anti-rotation structure includes a cylindrical member, specifically a bolt that can be threadedly connected to the second hole 211. The inner diameter of the first hole 222 is compatible with the outer diameter of the bolt. When the connecting locking device 200 locks the cross bar 111 located inside the movable groove 210, the pressing piece 220 rotates relative to the locking seat body 201, approaches and fits the notch 202, and the first hole 222 and the second hole 211 at the end of the pressing piece 220 are aligned. The bolt is threadedly installed in the second hole 211 and passes through the second hole 211. The end of the bolt is at least partially inserted into the first hole 222. At this time, the bolt penetrates the first hole 222 and the second hole 21 together, so that the bolt can firmly lock the pressing piece 220 to the locking seat body 201. Moreover, since the bolt is threadedly connected to the second hole 211, the bolt is not easy to move relative to the second hole 211. Therefore, the end of the bolt can be firmly inserted into the first hole 222, effectively preventing the bolt from accidentally falling out from the first hole 222, thereby limiting the rotation of the pressing piece 220 relative to the locking seat body 201.

[0048] It is understood that the connection locking device 200 may employ other structures besides the aforementioned structure consisting of a locking base body 201, a movable groove 210, a pressing member 220 rotatably mounted on the locking base body 201, and a locking crossbar 111. For example, the connection locking device 200 includes a locking base body 201, a movable groove 210 defined in the locking base body 201, and a threaded hole defined in one side of the movable groove 210, in which a locking bolt is threadedly mounted and screwed into the movable groove 210. When the locking mechanism 200 of this embodiment is in use, the locking seat body 201 is fixedly installed on one of the two adjacent door bodies 110, and the cross bar 111 of the other door body 110 is movably installed in the movable groove 210. When the cross bar 111 needs to be locked, the user can turn the locking bolt and make the locking bolt screw into the movable groove 210, so that the locking bolt can continuously press the cross bar 111 and lock the cross bar 111 in the movable groove 210. At this time, the relative positions of the two adjacent door bodies 110 are fixed, and the two door bodies 110 cannot move closer or farther away from each other; when the cross bar 111 needs to be released, the user only needs to turn the locking bolt in the opposite direction and make the locking bolt unscrewed from the movable groove 210. At this time, the locking bolt no longer presses the cross bar 111, and the cross bar 111 can move relative to the movable groove 210, and then the two adjacent door bodies 110 can freely move closer or farther away from each other, and the operation is simpler, more convenient and faster.

[0049] Reference Figures 4 to 8 To facilitate the installation of the connection locking device 200 on the door body 110, in certain embodiments of the present invention, the locking base body 201 is provided with a mounting groove 240 located on one side of the movable groove 210; the door body 110 is provided with a plug-in portion 120 that matches the mounting groove 240; when the locking base body 201 is fixedly installed on the door body 110, the plug-in portion 120 is inserted into the mounting groove 240. This structure simplifies and facilitates the assembly of the connection locking device 200 and the door body 110, helps improve the assembly efficiency of the connection locking device 200 and the door body 110, and reduces production costs.

[0050] Furthermore, to further secure the connection between the connecting and locking device 200 and the door body 110, in the present invention, a threaded through hole 241 is formed in the side wall of the mounting groove 240, into which a first bolt is threadedly installed. When the connecting and locking device 200 is assembled with the door body 110, the plug-in portion 120 of the connecting and locking device 200 is correspondingly inserted into the mounting groove 240 of the locking base body 201. The user then screws the first bolt into the mounting groove 240. The first bolt presses against and locks the plug-in portion 120, thereby preventing the plug-in portion 120 from being dislodged from the mounting groove 240. The locking base body 201 can then be securely mounted to the door body 110, thereby securing the connection between the connecting and locking device 200 and the door body 110.

[0051] Reference Figures 1 to 3 In order to make the locking between the two adjacent door bodies 110 more secure, in some embodiments of the present invention, at least two sets of connecting locking devices 200 are provided between the two adjacent door bodies 110, at least one set of connecting locking devices 200 fixes the upper part of the door body 110, and at least one set of connecting locking devices 200 fixes the lower part of the door body 110.

[0052] Specifically, in two adjacent door bodies 110, a set of connecting and locking devices 200 are fixedly installed on the upper and lower parts of each door body 110, and a cross bar 111 is provided on the upper and lower parts of each door body 110. When the two door bodies 110 are movably installed together, the cross bar 111 on the upper part of one door body 110 and the cross bar 111 on the lower part of the other door body 110 are installed in a one-to-one correspondence inside the movable groove 210 of the upper connecting and locking device 200 and the movable groove 210 of the lower connecting and locking device 200 of the other door body 110. By adopting the above structure, the connection between the two adjacent door bodies 110 can be made more reliable, and the two adjacent door bodies 110 can be locked and fixed by four sets of connecting and locking devices 200, thereby ensuring that the relative position between the two adjacent door bodies 110 remains unchanged and is less likely to change.

[0053] Reference Figures 1 to 3In certain embodiments of the present invention, a guardrail door capable of adjusting the overall width of a door body assembly further includes a door frame assembly. The door frame assembly includes a first door frame 310 and a second door frame 320 that are independent of each other. The first door frame 310 and the second door frame 320 are arranged at intervals in the vertical direction. The first door frame 310 is rotatably mounted on one side of the door body assembly 100. Specifically, one side of the door body assembly 100 is rotatably connected to the first door frame 310 via a hinge. The second door frame 320 is located on the other side of the door body assembly 100, and a locking device 400 is provided between the second door frame 320 and the door body assembly 100. The locking device 400 can lock the door body assembly 100 and the second door frame 320 together, or the locking device 400 can release the lock between the door body assembly 100 and the second door frame 320. Specifically, the locking device 400 includes a first connecting member and a second connecting member, each independent of the other. The first connecting member is fixedly mounted to the second door frame 320, while the second connecting member is fixedly mounted to the door body assembly 100. A latch hole is defined on the side of the first connecting member facing the second connecting member, and a latch is movably mounted on the second connecting member, which is capable of being inserted into the latch hole. When the latch is inserted into the latch hole, the locking device 400 locks the door body assembly 100 and the second door frame 320 together. When the latch is removed from the latch hole, the locking device 400 releases the lock between the door body assembly 100 and the second door frame 320. As the locking device 400 is well known in the art, its further description is omitted here.

[0054] The guardrail door of this embodiment adopts a first door frame 310 and a second door frame 320 that are independent of each other to form a door frame assembly, and the first door frame 310 and the second door frame 320 are correspondingly arranged on both sides of the door main body assembly 100. Therefore, when the overall width of the door main body assembly 100 changes, the first door frame 310 and the second door frame 320 can move synchronously with the change in the width of the door main body assembly 100, thereby making the overall width of the door frame assembly adapt to the overall width of the door main body assembly 100 to meet the user's usage needs.
