[0037] Referring to Figures 1 to 14 ( Figure 6 (in the direction of the arc arrow in [FIGURE REFERENCE] indicates the swinging direction of the second unlocking member 420), a guardrail door according to some embodiments of the present utility model includes a door frame 100, a door body 200, a locking mechanism 300, a first unlocking member 410 and a second unlocking member 420. A longitudinal slot 110 is provided at the lower part of the door frame 100, and the door body 200 is rotatably installed on the door frame 100. Specifically, one side wall of the door body 200 is rotatably installed on one inner wall of the door frame 100 through a hinge. A longitudinal bolt 210 capable of cooperating with the longitudinal slot 110 for locking is movably provided on the door body 200. The longitudinal bolt 210 can move along the longitudinal direction and insert into the inside of the longitudinal slot 110 or withdraw from the inside of the longitudinal slot 110. In this embodiment, when the door body 200 drives the longitudinal bolt 210 to rotate relative to the door frame 100 and makes the longitudinal bolt 210 aligned with the longitudinal slot 110, the longitudinal bolt 210 can, under the action of gravity, insert downward into the inside of the longitudinal slot 110.
[0038] The locking mechanism 300 includes a first connecting member 310 and a second connecting member 320 that can cooperate and lock with each other. The first connecting member 310 is mounted on the door frame 100, and the second connecting member 320 is mounted on the door body 200. In this embodiment, the first connecting member 310 is detachably mounted on the side of the door frame 100 away from the hinge, and the second connecting member 320 is detachably mounted on the side of the door body 200 away from the hinge. A transverse slot 311 is defined on the sidewall of the first connecting member 310 facing the second connecting member 320. The second connecting member 320 is movably provided with a transverse latch 321 that can cooperate and lock with the transverse slot 311. The transverse latch 321 can be moved transversely into or out of the transverse slot 311. A first unlocking member 410 is movably mounted on the second connecting member 320 and is in transmission connection with the transverse latch 321. The first unlocking member 410 can drive the transverse latch 321 to move transversely and out of the transverse slot 311. The second unlocking member 420 is movably mounted on the second connecting member 320. The second unlocking member 420 can be moved relative to the second connecting member 320 to an unlocked position or a locked position. The second unlocking member 420 is in a transmission connection with the longitudinal latch 210. When the second unlocking member 420 is in the locked position, the longitudinal latch 210 is inserted into the longitudinal slot 110, and the second unlocking member 420 can abut against the transverse latch 321 and restrict the transverse latch 321 from exiting the transverse slot 311. When the second unlocking member 420 moves relative to the second connecting member 320 to the unlocked position, the second unlocking member 420 can drive the longitudinal latch 210 to move longitudinally and exit the longitudinal slot 110. The second unlocking member 420 releases the restriction on the transverse latch 321, and the first unlocking member 410 can drive the transverse latch 321 to move transversely and exit the transverse slot 311.
[0039] By adopting the above structure, when the door body 200 rotates relative to the door frame 100 and aligns the first connecting member 310 and the second connecting member 320, the transverse bolt 321 moves along the transverse direction and inserts into the transverse slot 311, achieving the first-stage locking between the door body 200 and the door frame 100. The longitudinal bolt 210 correspondingly inserts into the longitudinal slot 110 along the longitudinal direction, achieving the second-stage locking between the door body 200 and the door frame 100, making the guardrail door of the present utility model have a double-locking structure. Moreover, when the second unlocking member 420 is in the locking position, the second unlocking member 420 can abut against the transverse bolt 321 and restrict the transverse bolt 321 from withdrawing from the inside of the transverse slot 311. Therefore, when the user does not drive the second unlocking member 420 to move to the unlocking position, the user cannot drive the transverse bolt 321 to withdraw from the inside of the transverse slot 311 through the first unlocking member 410, ensuring the locking effect between the transverse bolt 321 and the transverse slot 311, effectively preventing children from accidentally unlocking the locking mechanism 300, and thus greatly improving the safety performance of the guardrail door of the embodiment of the present utility model and better meeting the user's usage requirements.
[0040] Referring to Figures 6 to 8 , in order to enable the first unlocking member 410 to better drive the transverse bolt 321 to move and disengage from the inside of the transverse slot 311, in some embodiments of the present utility model, the second connecting member 320 is provided with a transverse chute 322 arranged along the transverse direction. The transverse bolt 321 is movably installed in the transverse chute 322. The transverse bolt 321 can move along the transverse chute 322 closer to or farther away from the transverse slot 311. The transverse bolt 321 is provided with a guiding inclined block 3210. The first unlocking member 410 is movably installed on the second connecting member 320 and is located above the transverse bolt 321. Among them, when the first unlocking member 410 moves downward relative to the second connecting member 320, the first unlocking member 410 can abut against the guiding inclined block 3210 and push the transverse bolt 321 away from the transverse slot 311. By adopting the above structure, when the user squeezes the first unlocking member 410 to move downward, the first unlocking member 410 can drive the transverse bolt 321 away from the transverse slot 311, and the operation is simpler and more convenient.
[0041] In some embodiments of the present utility model, a longitudinal chute 323 arranged along the longitudinal direction is provided at the upper part of the second connecting member 320. A communication port 324 is provided between the longitudinal chute 323 and the transverse chute 322. The first unlocking member 410 is movably installed inside the longitudinal chute 323. A first pushing portion 411 is provided at the lower part of the first unlocking member 410. The first pushing portion 411 passes through the communication port 324 and abuts against the guiding inclined block 3210. When the first unlocking member 410 moves downward along the longitudinal chute 323, the first pushing portion 411 presses and pushes the guiding inclined block 3210, causing the transverse bolt 321 to move away from the transverse slot 311. By adopting the above structure, the movement of the first unlocking member 410 and the transverse bolt 321 relative to the second connecting member 320 is smoother, and it is convenient to install the first unlocking member 410 and the transverse bolt 321 on the second connecting member 320.
[0042] In some embodiments of the present utility model, a first elastic member is provided inside the transverse chute 322. One end of the first elastic member abuts against the transverse bolt 321, and the other end of the first elastic member abuts against the inner wall of the transverse chute 322. The first elastic member can push the transverse bolt 321 to move along the transverse chute 322 and approach the transverse slot 311. Specifically, the first elastic member is a compression spring. The compression spring is installed inside the transverse chute 322. One end of the compression spring abuts against the transverse bolt 321, and the other end of the compression spring abuts against the inner wall of the transverse chute 322. In the initial state, the compression spring is in a compressed state. Therefore, the compression spring applies a force to the transverse bolt 321 and causes the transverse bolt 321 to move outwards of the transverse chute 322. By adopting the above structure, after the transverse bolt 321 is inserted into the transverse slot 311, the transverse bolt 321 will not accidentally disengage from the transverse slot 311, ensuring that the locking between the transverse bolt 321 and the transverse slot 311 is firm and reliable. It can be understood that in addition to adopting the above structure of the compression spring, the first elastic member can also adopt other structures, such as the first elastic member being a straight strip-shaped silica gel rod or rubber rod, etc., which is also acceptable, and can be specifically determined according to actual needs.
[0043] It should be noted that in addition to adopting the above unlocking structure, the first unlocking member 410 can also adopt other structures. For example, the first unlocking member 410 is fixedly installed on the upper part of the transverse bolt 321, and the first unlocking member 410 protrudes from the upper part of the second connecting member 320. Therefore, the user can apply a force to the first unlocking member 410 and drive the first unlocking member 410 to move away from the first connecting member 310 along the transverse direction. At this time, the first unlocking member 410 can drive the transverse bolt 321 to move along the transverse direction and disengage from the inside of the transverse slot 311, releasing the locking between the transverse bolt 321 and the transverse slot 311. The operation is simple and convenient, and can be specifically determined according to actual needs.
[0044] In order to enable the second unlocking member 420 to better drive the longitudinal pin 210 to move along the longitudinal direction to disengage from the transverse slot 311, in certain embodiments of the present invention, one end of the second unlocking member 420 is rotatably mounted on the second connecting member 320, and the other end of the second unlocking member 420 is transmission-connected to the longitudinal pin 210; wherein the second unlocking member 420 can swing upward relative to the second connecting member 320 and drive the longitudinal pin 210 to move along the longitudinal direction to disengage from the transverse slot 311. Specifically, a rotating groove 3201 is provided at the lower portion of the second connecting member 320, and a rotating end 4201 adapted to the rotating groove 3201 is provided at one end of the second unlocking member 420, and the rotating end 4201 is movably inserted into the rotating groove 3201, and a toggle groove 4202 is provided at the other end of the second unlocking member 420 away from the rotating end 4201, and a snap-fitting member 2101 is provided at the upper portion of the longitudinal pin 210, and the snap-fitting member 2101 is snap-fitted into the toggle groove 4202; wherein, when the second unlocking member 420 swings upward around the rotating end 4201, the toggle groove 4202 cooperates with the snap-fitting member 2101 and drives the longitudinal pin 210 to move upward and disengage from the transverse slot 311. By adopting the above structure, the user only needs to press the second unlocking member 420 and swing the second unlocking member 420 upward around the rotating end 4201. The second unlocking member 420 can cooperate with the snap-on member 2101 through the toggle slot 4202 and drive the longitudinal pin 210 to move upward and disengage from the transverse slot 311. The operation is simpler and more convenient, which is convenient for users to operate.
[0045] Reference Figures 6 to 8 In certain embodiments of the present invention, an abutment portion 4203 is provided on the upper portion of the end of the second unlocking member 420 away from the rotating end 4201. The abutment portion 4203 is located on one side of the toggle slot 4202 and faces the transverse latch 321. In this embodiment, when the second unlocking member 420 is in the locked position, the longitudinal latch 210 is inserted into the longitudinal slot 110, and the abutment portion 4203 is located on the side of the transverse latch 321 away from the transverse slot 311. When the transverse latch 321 moves away from the transverse slot 311, the abutment portion 4203 abuts against the transverse latch 321 and restricts the transverse latch 321 from exiting the transverse slot 311. When the second unlocking member 420 swings upward around the rotating end 4201 and moves to the unlocking position, the abutting portion 4203 swings upward and is misaligned with the transverse latch 321, so that the abutting portion 4203 no longer abuts against the transverse latch 321, releasing the restriction on the transverse latch 321, so that the first unlocking member 410 can drive the transverse latch 321 to move in the transverse direction and exit from the inside of the transverse slot 311.
[0046] Reference Figure 9 and Figure 10To facilitate the installation of the longitudinal latch 210 on the door body 200, in certain embodiments of the present invention, the door body 200 is provided with a longitudinal tube 220 corresponding to the longitudinal slot 110. The longitudinal tube 220 is hollow, and the longitudinal latch 210 is movably mounted within the longitudinal tube 220. The upper sidewall of the longitudinal tube 220 is provided with a longitudinally arranged strip groove 2201. The engaging member 2101 passes through the strip groove 2201 and is embedded in the toggle groove 4202. The longitudinal latch 210 can be moved downward along the longitudinal tube 220 to be inserted into the longitudinal slot 110, or moved upward along the longitudinal tube 220 to be removed from the longitudinal slot 110. This structure not only facilitates the installation of the longitudinal latch 210 on the door body 200, but also facilitates the engagement of the engaging member 2101 on the upper portion of the longitudinal latch 210 with the toggle groove 4202 of the second unlocking member 420, thus facilitating assembly.
[0047] In certain embodiments of the present invention, a fixing base 120 is detachably mounted on the lower portion of the door frame 100, and a longitudinal slot 110 is formed above the fixing base 120. The door body 200 can rotate relative to the door frame 100 so that the longitudinal latch 210 is positioned above the longitudinal slot 110. By adopting this structure, the user can adjust the position of the longitudinal slot 110 by installing the fixing base 120 at different positions on the lower portion of the door frame 100, thereby allowing the longitudinal latch 210 to be inserted into the longitudinal slot 110 along the longitudinal direction.
[0048] Reference Figure 1 、 Figure 2 、 Figures 4 to 8 To facilitate assembly of the door frame 100 and the door body 200, in certain embodiments of the present invention, a first engaging portion 330 is provided on one end of the first connecting member 310 facing the second connecting member 320, and a second engaging portion 340 is provided on one end of the second connecting member 320 facing the first connecting member 310, which is detachably engageable with the first engaging portion 330. During installation, the first connecting member 310 can be first installed on the door frame 100, and the second connecting member 320 can be installed on the door body 200. When the door body 200 is installed on the door frame 100, the first engaging portion 330 and the second connecting member 320 can be engaged with each other, thereby tightly attaching the side wall of the door frame 100 and the door body 200 together, preventing the side wall of the door frame 100 from separating from the door body 200. This solves the technical problem of traditional installation methods that require manual pressing of the side wall of the door frame 100 and the door body 200 together.
[0049] Furthermore, the first clamping portion 330 and the first connecting member 310 are of an integral structure, and the second clamping portion 340 and the second connecting member 320 are of an integral structure. Specifically, the first clamping portion 330 and the first connecting member 310 are integrally injection molded, and the second clamping portion 340 and the second connecting member 320 are integrally injection molded. By adopting the above structure, it is convenient for the production and processing of the first connecting member 310 and the second connecting member 320, and helps to reduce the production costs of the first connecting member 310 and the second connecting member 320.
[0050] Refer to Figure 1 , Figure 2 , Figure 11 , Figure 12 , Figure 13 and Figure 14 , in order to make the door body 200 rotate better relative to the door frame 100, a guardrail door according to some embodiments of the present invention includes a door frame 100, a door body 200, a locking mechanism 300, a first unlocking member 410, a second unlocking member 420, and a rotating device 500. A longitudinal slot 110 is provided at the lower part of the door frame 100, and the door body 200 is rotatably installed on the door frame 100 through the rotating device 500. Specifically, the rotating device 500 includes a fixed seat 510 and a rotating member 520 that can be rotatably installed on the fixed seat 510. In this embodiment, the fixed seat 510 is fixedly installed on the upper part of one side of the door frame 100, and the rotating member 520 is fixedly installed on the upper part of one side wall of the door body 200. When the door body 200 is installed on the door frame 100, the rotating member 520 is rotatably installed on the fixed seat 510. Therefore, the door body 200 can rotate relative to the fixed seat 510 following the rotating member 520, and further makes the door body 200 rotate more smoothly relative to the door frame 100. By adopting the above structure, the door body 200 of the guardrail door in this embodiment can rotate more smoothly and labor-savingly and is not prone to jamming when rotating.
[0051] It should be noted that in the above embodiment, the fixed seat 510 is fixedly installed on the upper part of one side of the door frame 100, and the rotating member 520 is fixedly installed on the upper part of one side wall of the door body 200. In some embodiments of the present invention, the fixed seat 510 and the rotating member 520 can adopt other installation structures. For example, the fixed seat 510 is fixedly installed on the upper part of one side wall of the door body 200, and the rotating member 520 is fixedly installed on the upper part of one side of the door frame 100. When the door body 200 is installed on the door frame 100, the rotating member 520 is rotatably installed on the fixed seat 510. By adopting the above structure, the door body 200 can also rotate more smoothly relative to the door frame 100.
[0052] Refer to Figures 11 to 14, in order to facilitate the rotatable installation of the rotating member 520 on the fixed seat 510, in some embodiments of the present invention, a rotating shaft hole 511 is formed on one side of the fixed seat 510, and the rotating member 520 has a rotating shaft 521 that can be rotatably inserted into the inside of the rotating shaft hole 511. When the rotating member 520 is assembled to the fixed seat 510, it only needs to correspondingly insert the rotating shaft 521 of the rotating member 520 into the inside of the rotating shaft hole 511 of the fixed seat 510, and the assembly is simple and convenient.
[0053] In order to make the assembly between the rotating member 520 and the fixed seat 510 more firm, in some embodiments of the present invention, the rotating device 500 further includes an end cover member 530. The rotating shaft hole 511 is a variable-diameter hole, that is, the rotating shaft hole 511 includes a small-diameter section with a smaller upper diameter and a large-diameter section with a larger lower diameter. Therefore, a step 512 is formed at the connection between the upper-diameter section and the large-diameter section. The end cover member 530 can be rotatably installed in the large-diameter section of the rotating shaft hole 511, and the end cover member 530 can be engaged with the step 512. A through hole is formed in the center of the rotating shaft 521. When the rotating member 520 is installed on the fixed seat 510, the rotating shaft 521 is rotatably inserted into the inside of the rotating shaft hole 511 along the direction from top to bottom, and the end cover member 530 is rotatably installed in the large-diameter section of the rotating shaft hole 511. Then, a rivet is used to pass through the through hole in the center of the rotating shaft 521 and rivet it with the end cover member 530. By adopting the above structure, the rotating shaft 521 and the end cover member 530 are riveted together and are not easily loosened and separated, so that the rotating shaft 521 is firmly installed inside the rotating shaft hole 511, and further the rotating member 520 and the fixed seat 510 can cooperate to rotatably connect the door main body 200 and the door frame 100 together, effectively preventing the separation of the main body 200 and the door frame 100.
[0054] In order to enable the door main body 200 to rotate relative to the door frame 100 in a positioned manner, in some embodiments of the present invention, the fixed seat 510 is provided with a rotating seat 540. The rotating shaft hole 511 is formed at the center of the rotating seat 540 and penetrates the rotating seat 540 along the longitudinal direction. At least three positioning grooves are formed at the upper end of the rotating seat 540. In this embodiment, three positioning grooves are formed at the upper end of the rotating seat 540, and the three positioning grooves are arranged at equal intervals around the outer circumference of the rotating shaft hole 511, and the included angle between two adjacent positioning grooves is a right angle. As Figure 12As shown, the three positioning grooves are respectively the first positioning groove 541, the second positioning groove 542 and the third positioning groove 543. The included angle between the first positioning groove 541 and the second positioning groove 542 is a right angle, and the included angle between the second positioning groove 542 and the third positioning groove 543 is a right angle. Therefore, the first positioning groove 541 and the third positioning groove 543 are located on the same radial of the rotating shaft hole 511. On the side wall of the rotating member 520 facing the rotating shaft hole 511, at least one positioning block 522 that can cooperate with the positioning groove for positioning is provided. The positioning block 522 is located on one side of the rotating shaft 521. In this embodiment, the number of the positioning blocks 522 is two, and the two positioning blocks 522 are correspondingly arranged on both sides of the rotating shaft 521, and the two positioning blocks 522 are located on the same radial of the rotating shaft 521. When the rotating member 520 is installed on the fixed seat 510, the rotating shaft 521 is inserted into the rotating shaft hole 511, and the positioning block 522 abuts against the upper end of the rotating seat 540. When the rotating member 520 rotates relative to the fixed seat 510, the positioning block 522 rotates synchronously along the upper end of the rotating seat 540. When the positioning block 522 is embedded in the first positioning groove 541 or the second positioning groove 542 or the third positioning groove 543, the positioning rotation of the rotating member 520 relative to the fixed seat 510 can be realized, and further the positioning rotation of the door main body 200 relative to the door frame 100 can be realized.
[0055] Furthermore, in order to enable the door main body 200 to automatically position at the positioning groove when rotating relative to the door frame 100, in some embodiments of the present utility model, the surface between two adjacent positioning grooves is an arc segment. Specifically, the surface corresponding to the first positioning groove 541 and the second positioning groove 542 on the upper end of the rotating seat 540 is an arc surface, and the surface corresponding to the second positioning groove 542 and the third positioning groove 543 on the upper end of the rotating seat 540 is an arc surface. The rotating shaft 521 is rotatably installed inside the rotating shaft hole 511, and the rotating shaft 521 is rotatably inserted into the rotating shaft hole 511 and riveted with the end cover member 530. A return spring is sleeved on the outer peripheral wall of the rotating shaft hole 511. One end of the return spring abuts against the step 512, and the other end of the return spring abuts against the cover member 530. When the door main body 200 rotates relative to the door frame 100, the rotating member 520 rotates around the rotating shaft 521 and makes the positioning block 522 slide out of the first positioning groove 541 or the second positioning groove 542 or the third positioning groove 543. Under the reset acting force of the return spring, the return spring can drive the rotating member 520 to slide along the arc surface of the upper end of the rotating seat 540 and be embedded in the adjacent positioning groove, so as to realize that the door main body 200 can automatically position at the positioning groove when rotating relative to the door frame 100, and the operation is simple, convenient and fast.
[0056] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the relevant technical field.
