Description

Technical Field

[0001] This utility model relates to the field of subway facility technology, specifically to a novel subway side door. Background Technology

[0002] Subway side doors are typically used in subway stations for subway staff, disabled persons, and emergency exits. However, the installation and assembly of subway side doors has always been an easily overlooked point. There are two main existing solutions: (1) Electromagnetic lock solution. During use, the armature makes a loud noise when it engages, and there are some cases where the engagement is not firm. Moreover, the installation is not aesthetically pleasing. Some are directly welded on-site, while others are installed using irregularly shaped columns, which is inconvenient for construction and easy to scratch. Furthermore, electromagnetic locks are expensive. (2) Exposed lock solution. Exposed locks are directly installed, which is not convenient. In the event of a fire, they cannot be opened automatically and require manual unlocking, which cannot meet the requirements of modern technology.

[0003] On December 1, 2020, the applicant filed a Chinese utility model patent application, application number CN2020228373691, which discloses a subway side door. The subway side door adopts an electric bolt lock scheme, which has low manufacturing and installation costs and is reliable in use; it uses hydraulic hinges, which are quiet and easy to position, making it convenient to open and close and easy to use. However, we found some shortcomings in the practical application of this subway side door: When the side door closes, it may not close completely, causing inaccurate positioning between the electric bolt lock body and the electric bolt lock armature. This results in the bolt of the electric bolt lock body not being able to accurately and easily insert into the socket of the electric bolt lock armature, preventing the subway side door from locking. This also damages the electric bolt lock, eventually leading to damage and significantly shortening its lifespan, necessitating repair or replacement and increasing costs. The control lines between the card reader and the electric bolt lock body are conventionally connected by direct soldering, which is inconvenient for on-site construction, making it difficult to disassemble and install the card reader, and hindering maintenance. Hydraulic hinges are expensive, and for subways with high passenger flow and frequent side door opening, the wear and tear on hydraulic hinges is significant, making them clearly unsuitable.

[0004] Therefore, the applicant has further optimized and improved the subway side doors. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a new type of subway side door.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel subway side door, comprising a side door body, railings disposed on the left and right sides of the side door body, an electric bolt lock body, an electric bolt lock armature, and a card reader. The electric bolt lock body is embedded in the right side of the right post of the left railing. The electric bolt lock armature is embedded in the left side of the left frame of the side door body. The right frame of the side door body is hinged to the left post of the right railing. The card reader is embedded in the upper front side of the right post of the left railing. Handrails are provided at the top of both the railings and the top of the side door body. The handrail on the pole has a positioning groove at the center of the right end face, and a positioning bead is embedded in the center of the left end face of the handrail on the side door body. The end of the positioning bead with the ball protrudes from the left end face of the handrail on the side door body. The positioning groove is a hemispherical groove that matches the shape of the ball of the positioning bead. When the side door body is closed, the handrail on the railing and the handrail on the side door body are exactly on the same straight line. The ball of the positioning bead extends out and locks in the positioning groove, positioning the side door body so that the electric bolt lock body and the electric bolt lock armature are aligned left and right. The bolt of the electric bolt lock body can be inserted into the corresponding hole of the electric bolt lock armature. The card reader is connected to the control line of the electric bolt lock body via a connector or terminal block; The right side frame of the side door body is hinged to the left post of the railing on the right side by a number of positioning hinges.

[0007] Based on the above, the upper part of the front side of the right column of the left railing is provided with a mounting hole that matches the shape of the card reader. The card reader is provided with a spring clip, and the card reader is embedded and locked in the mounting hole by the elastic pressure of the deformation of the spring clip.

[0008] Based on the above, the spring is made of 65Mn through a quenching process.

[0009] Based on the above, the spring is divided into three sections: left, middle, and right. The left and right sections of the spring are symmetrically arranged about the middle section. The middle section of the spring is connected to the rear side of the card reader by screws or bolts. The left section of the spring bends forward and extends to the left side of the card reader, and the right section of the spring bends forward and extends to the right side of the card reader.

[0010] Based on the above, there are two spring pieces arranged at intervals, one on the upper side and one on the lower side. The upper spring piece has three straight sections, while the lower spring piece has two arched sections on the left and right sides and a straight section in the middle.

[0011] Based on the above, there are two spring pieces spaced apart vertically, and all three segments of the two spring pieces are straight pieces.

[0012] Based on the above, there are two spring pieces arranged at intervals, with the left and right sides of the two spring pieces being arched curved pieces and the middle section being a straight piece.

[0013] Based on the above, a caster that rolls on the ground is provided on the bottom left side of the lower frame of the side door body.

[0014] This utility model has substantial features and advancements compared to existing technologies. Specifically, it adds a positioning bead device to the existing subway side door, ensuring accurate positioning between the electric bolt lock body and the electric bolt lock armature when the subway side door is closed. This allows the bolt of the electric bolt lock body to be accurately and conveniently inserted into the socket of the electric bolt lock armature, reducing damage to the electric bolt lock, increasing its service life, and lowering equipment costs. Furthermore, the control line between the card reader and the electric bolt lock body is connected via connectors or terminals, eliminating the need for soldering equipment, facilitating construction, subsequent maintenance, and repair. The card reader is also easier to install and remove. Using a positioning hinge instead of a hydraulic hinge reduces equipment costs. Additionally, the positioning hinge stabilizes the side door body at a certain angle, preventing automatic closure. In high-traffic areas, this reduces the frequency of opening the side door, resulting in less wear and tear. Compared to hydraulic hinges, positioning hinges are more suitable for this location.

[0015] In summary, this utility model can ensure accurate positioning between the electric bolt lock body and the electric bolt lock armature when the subway side door is closed, improve the service life of the electric bolt lock, and make the card reader easy to disassemble, maintain and repair, with low equipment cost.

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0024] Example 1 like Figures 1-6 As shown, a new type of subway side door includes a side door body 1, railings 2 disposed on the left and right sides of the side door body 1, an electric bolt lock body 3, an electric bolt lock armature 4, and a card reader 5. The electric bolt lock body 3 is embedded in the right side of the right post 6 of the left railing 2. The electric bolt lock armature 4 is embedded in the left side of the left frame of the side door body 1. The right frame of the side door body 1 is hinged to the left post 6 of the right railing 2. The card reader 5 is embedded in the upper front side of the right post 6 of the left railing 2. Handrails 7 are provided at the top of both the railings 2 and the side door body 1. The center of the right end face of the handrail 7 on the left railing 2 is... The side door body 1 has a positioning groove 8. A positioning bead 9 is embedded in the center of the left end face of the handrail 7 on the side door body 1. The end of the positioning bead 9 with a ball protrudes from the left end face of the handrail 7 on the side door body 1. The positioning groove 8 is a hemispherical groove that matches the shape of the ball of the positioning bead 9. When the side door body 1 is closed, the handrail 7 on the railing 2 and the handrail 7 on the side door body 1 are exactly on the same straight line. The ball of the positioning bead 9 extends out and is locked in the positioning groove 8, positioning the side door body 1 so that the electric bolt lock body 3 and the electric bolt lock armature 4 are aligned left and right. The bolt of the electric bolt lock body 3 can be inserted into the corresponding hole of the electric bolt lock armature 4. The control line of the card reader 5 and the electric bolt lock body 3 is connected by a connector or terminal block; The right side frame of the side door body 1 is hinged to the left side post 6 of the right railing 2 via several positioning hinges 10. The positioning hinges 10 are fixedly connected to the right side frame of the side door body 1 and the left side post 6 of the right railing 2 via rigid rivets.

[0025] The positioning groove 8 is designed as a hemispherical groove, which can serve a positioning function and also allow the ball of the positioning bead 9 to make smooth contact with the arc surface of the positioning groove 8 when the side door body 1 is opened. The ball is compressed and returned more smoothly, so that the ball of the positioning bead 9 can slide out of the positioning groove 8 smoothly, thus avoiding the side door body 1 being difficult to open.

[0026] The upper part of the front side of the right column 6 of the railing 2 on the left side is provided with a mounting hole 11 that matches the shape of the card reader 5. The card reader 5 is provided with a spring piece 12. The card reader 5 is embedded and locked in the mounting hole 11 by the elastic pressure of the deformation of the spring piece 12.

[0027] The two side posts 6 of the railing 2 and the four side frames of the side gate body 1 are all square tube structures. The electric bolt lock body 3 is embedded inside the right side post 6 of the left railing 2, and the right side of the right side post 6 of the left railing 2 has a first elongated hole for installing the electric bolt lock body 3. A first fixing member for fixing the electric bolt lock body 3 is pre-welded into the first elongated hole. The control line of the electric bolt lock body 3 is arranged inside the right side post 6 of the left railing 2, which is more aesthetically pleasing and facilitates wiring. This allows the control line of the electric bolt lock body 3 to be arranged upward to the position of the mounting hole 11 for connection with the card reader 5. Similarly, the electric bolt lock armature 4 is embedded in the left side frame of the side gate body 1, and the left side of the left side frame of the side gate body 1 has a second elongated hole for installing the electric bolt lock armature 4. A second fixing member for fixing the electric bolt lock armature 4 is pre-welded into the second elongated hole.

[0028] In this embodiment, the spring sheet 12 is made of 65Mn through a quenching process. The spring sheet 12 has excellent elastic properties and can be used by repeated compression and bending.

[0029] When the card reader 5 is installed on site, it can be directly pressed into the mounting hole 11 and secured in the mounting hole 11 by the elastic pressure generated by the compression deformation of the spring piece 12. No screws or welding are required to fix the card reader 5. During inspection and maintenance, the card reader 5 can be pulled out of the mounting hole 11 by applying force, making disassembly and assembly convenient and quick.

[0030] The spring 12 is divided into three sections: left, middle, and right. The left and right sections of the spring 12 are symmetrically arranged about the middle section. The middle section of the spring 12 is connected to the rear side of the card reader 5 by screws or bolts. The left section of the spring 12 bends forward and extends to the left side of the card reader 5, and the right section of the spring 12 bends forward and extends to the right side of the card reader 5.

[0031] Two spring pieces 12 are arranged at intervals on the top and bottom. The upper spring piece 12 has three straight sections, while the lower spring piece 12 has an arched curved section on the left and right sides and a straight section in the middle.

[0032] The bottom left side of the lower frame of the side door body 1 is provided with casters 13 that roll on the ground, which serve to provide stable support and facilitate the movement of the side door body 1.

[0033] Under normal conditions, the side door body 1 is in the closed state. At this time, the electric bolt lock body 3 remains energized, and the pin of the electric bolt lock body 3 is inserted into the socket of the electric bolt lock armature 4, locking the side door body 1. When the side door body 1 is opened, a card is swiped on the card reader 5. The card reader 5 reads the card swiping command, then the electric bolt lock body 3 is de-energized, the pin of the electric bolt lock body 3 retracts, and pushing the side door body 1 compresses the ball of the positioning bead 9, allowing it to slide smoothly out of the positioning groove 8, opening the side door body 1. After the side door body 1 is opened to a certain angle, the positioning hinge 10 can position the side door body 1. After a certain delay, the electric bolt lock body 3 is re-energized, and when... When the side door body 1 is closed and the handrail 7 on the railing 2 and the handrail 7 on the side door body 1 are exactly on the same straight line, the positioning bead 9 is aligned with the positioning groove 8, the ball of the positioning bead 9 extends out and locks in the positioning groove 8, positioning the side door body 1. At the same time, the electric bolt lock body 3 and the electric bolt lock armature 4 are aligned left and right. Under the action of the electric bolt lock armature 4, the bolt of the electric bolt lock body 3 is re-inserted into the socket of the electric bolt lock armature 4, locking the side door body 1.

[0034] This invention adds a positioning bead 9 device to the existing subway side door, which ensures accurate positioning between the electric bolt lock body 3 and the electric bolt lock armature 4 when the subway side door is closed. This allows the bolt of the electric bolt lock body 3 to be accurately and conveniently inserted into the socket of the electric bolt lock armature 4, reducing damage to the electric bolt lock, increasing its service life, and lowering equipment costs. Moreover, the control line between the card reader 5 and the electric bolt lock body 3 is connected via connectors or terminals, eliminating the need for soldering equipment, making construction convenient, and facilitating subsequent maintenance and repair. The card reader 5 is also easier to install and remove. Using the positioning hinge 10 instead of a hydraulic hinge reduces equipment costs. Furthermore, the positioning hinge 10 can stabilize the side door body 1 at a certain angle, preventing it from closing automatically. In situations with high pedestrian traffic, this reduces the frequency of opening the side door body 1, resulting in less wear and tear. Compared to hydraulic hinges, the positioning hinge 10 is more suitable for this location.

[0035] Example 2 Unlike Embodiment 1, there are two spring sheets spaced apart vertically, and all three segments of the two spring sheets are straight pieces.

[0036] Example 3 Unlike Embodiment 1 or 2, there are two spring pieces spaced apart vertically. The left and right sections of the two spring pieces are arched curved pieces, and the middle section is a straight piece.

[0037] In other embodiments, one or more spring clips may be provided.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
