Description

Technical Field

[0001] The utility model relates to the technical field of rail-type logistics transmission, and particularly relates to a self-closing windproof door and a logistics rail system with the self-closing windproof door. Background Art

[0002] In the modern medical environment, due to its mature technology and accurate distribution capabilities, the rail-type logistics transmission system has been widely used in the new construction, renovation, and expansion projects of hospitals, greatly improving the internal logistics efficiency and medical service quality of hospitals.

[0003] However, in the design and use process, the rail-type logistics transmission system still faces an important challenge, that is, how to handle the design problem of the windproof door when the logistics trolley passes through different spaces to ensure the safety and tightness of the building space. The traditional windproof door design mostly adopts an elastic self-closing mechanism, allowing the logistics trolley to knock it open when passing through and naturally reset and close after the trolley passes through. But this design has several significant deficiencies:

[0004] First of all, under the action of the impact force, the elastic self-closing windproof door is prone to wear and damage, resulting in a short service life. This not only increases the operating cost of the hospital but also affects the overall efficiency of the logistics transmission system due to frequent maintenance work.

[0005] Secondly, the noise generated when the logistics trolley impacts and passes through the windproof door will cause interference to both medical staff and patients, affecting the medical experience and treatment effect.

[0006] In addition, most of the existing windproof doors adopt the so-called shock absorption measures by directly pasting anti-collision strips on the door panels. However, the pasted anti-collision strips are not firm enough and are easy to fall off. Moreover, because the anti-collision strips are mostly flexible protective materials, they will be damaged after long-term collisions and lose their protective effects, requiring regular maintenance, resulting in an increase in the later maintenance cost.

[0007] In view of this, based on years of production design experience in this field and related fields, the inventor has designed a self-closing windproof door and a logistics rail system with the self-closing windproof door through repeated tests, in order to solve the problems existing in the prior art.

The guiding column can be slidably matched with the top seat and the bottom seat respectively in its axial direction, and two ends of the spring respectively abut against the top seat and the bottom seat.

[0012] For the self-closing windproof door as described above, an installation groove is formed on the surface of the panel, and the buffer frame is installed in the installation groove.

[0040] Unless otherwise defined, the up, down, left, right and other directions involved herein are based on the up, down, left, right and other directions shown in the present utility model, and are hereby explained together. Figure 1 in the present utility model, and are hereby explained together.

[0041] As Figures 1 to 5 shown, the present utility model provides a self-closing windproof door 100, which includes a door panel 10 and at least one rolling guiding device 20. The rolling guiding device 20 is arranged on the surface of the door panel 10. The rolling guiding device 20 has a buffer frame 21 and a plurality of rolling guiding members 22. The buffer frame 21 is elastically arranged on the surface of the panel, and each rolling guiding member 22 is rotatably installed on the buffer frame 21.

[0042] The self-closing windproof door 100 proposed by the utility model is installed on the logistics track 200 and allows the logistics trolley 300 to knock it open when passing. When the logistics trolley 300 hits the door panel 10, the multiple rolling guides 22 on the rolling guide device 20 can convert the sliding friction between the logistics trolley 300 and the door panel 10 into rolling friction, thereby effectively reducing the wear and damage caused by the impact on the door panel 10 and extending the service life of the self-closing windproof door 100. In addition, the buffer frame 21 for installing the rolling guide 22 is elastically arranged on the board surface of the door panel 10, which can buffer the vibration generated by the logistics trolley 300 when it hits, thereby having the effect of shock absorption and noise reduction.

[0043] The utility model also proposes a logistics track system with a self-closing windproof door, the logistics track system includes a logistics track 200 and at least one logistics trolley 300 arranged on the track, the logistics track 200 passes through at least one isolation wall 400, and holes are opened on the isolation wall 400 to allow the logistics track 200 and the logistics trolley 300 to pass through, at least one self-closing windproof door 100 is installed in the hole, and the door panel 10 is hinged on the isolation wall 400 and can open and close the hole.

[0044] The logistics track system with self-closing windproof doors proposed by the utility model, the impact force and friction force generated by the logistics cart 300 when colliding with the self-closing windproof door 100 are mitigated by the rolling guide device 20, thereby extending the service life of the self-closing windproof door 100 and reducing the maintenance cost of the entire logistics track system of the self-closing windproof door; at the same time, the rolling guide device 20 on the self-closing windproof door 100 also effectively reduces the noise generated when the logistics cart 300 passes through, so that the logistics track system with self-closing windproof doors has a quieter operating environment and is more suitable for medical environments.

[0045] In an optional embodiment of the present invention, the door panel 10 is hinged to the partition wall 400 through a self-closing two-way spring hinge 40. With the above structure, the door panel 10 can rotate in both directions relative to the wall of the partition wall 400, and can always remain closed or maintain a closing trend through the self-restoring force of the self-closing two-way spring hinge 40.

[0046] In an optional embodiment of the present invention, as Figure 1 As shown, two self-closing windproof doors 100 are installed at the hole, and the two self-closing windproof doors 100 are in a double-opening form.

[0047] In an alternative embodiment of the present utility model, a plurality of telescopic shock-absorbing components 23 are provided between the buffer frame 21 and the plate surface. The plurality of telescopic shock-absorbing components 23 are arranged at intervals in sequence. Each telescopic shock-absorbing component 23 includes a top seat 231, an elastic telescopic member, and a bottom seat 232 arranged in sequence. The top seat 231 is fixedly connected to the buffer frame 21, the bottom seat 232 is fixedly connected to the plate surface, and both ends of the elastic telescopic member are respectively connected to the top seat 231 and the bottom seat 232. With the above structure, when the buffer frame 21 is impacted by the logistics trolley 300, the impact force can be transmitted from the buffer frame 21 to the telescopic shock-absorbing component 23. Through the contraction of the telescopic shock-absorbing component 23, the buffering of the impact force and the vibration generated by the impact force is realized, not only reducing the wear and damage caused by the impact, but also reducing the noise generated by the impact.

[0048] In an alternative example of this embodiment, the elastic telescopic member includes a guide post 233 and a spring 234 sleeved outside the guide post 233. One end of the guide post 233 extends into the top seat 231, the other end of the guide post 233 extends into the bottom seat 232, and the guide post 233 can be slidably matched with the top seat 231 and the bottom seat 232 respectively in its axial direction. Both ends of the spring 234 respectively abut against the top seat 231 and the bottom seat 232.

[0049] In an alternative embodiment of the present utility model, an installation groove is opened on the plate surface, and the buffer frame 21 is installed in the installation groove. Further, the telescopic shock-absorbing component 23 is installed at the bottom of the installation groove. A part of the buffer frame 21 is located in the installation groove, and the other part of the buffer frame 21 and the rolling guide member 22 are located outside the installation groove.

[0050] In an alternative example of this embodiment, after the logistics trolley 300 impacts the door panel 10, the door panel 10 opens, and the logistics trolley 300 passes through accordingly and forms an impact track on the door panel 10. The installation groove is opened along the impact track, so as to ensure that when the logistics trolley 300 passes through, the logistics trolley 300 is always in rolling cooperation with the rolling guide device 20.

[0051] In an alternative embodiment of the present utility model, the rolling guide member 22 is a roller.

[0052] Further, the rotation axis of the roller is perpendicular to the impact track, and a plurality of rollers are arranged in sequence along the impact track. With the above structure, when the logistics trolley 300 impacts the door panel 10, it sequentially passes through a plurality of rolling guide members 22 and is in rolling cooperation with the rolling guide members 22 to achieve buffer force unloading.

[0053] In an alternative example of this embodiment, an elastic buffer layer is provided on the outer cylindrical wall of the roller to further relieve the impact force between the logistics trolley 300 and the rolling guide device 20.

[0054] In an optional example, the elastic buffer layer is made of rubber.

[0055] In an optional embodiment of the present invention, rolling guide devices 20 are installed on both sides of the door panel 10 to ensure that buffering and shock absorption can be achieved when the logistics cart 300 hits the self-closing windproof door 100 in two directions.

[0056] In an optional embodiment of the present invention, the door panel 10 has a hinged side and an opening side that are relatively arranged, and a first buffer roller 30 is rotatably mounted on the opening side to buffer the impact received by the door panel 10 when closing.

[0057] In another optional example of this embodiment, the self-closing bidirectional spring hinge 40 is installed on the hinge side.

[0058] In an optional embodiment of the utility model, a second buffer roller 310 is installed on the logistics trolley 300, and the second buffer roller 310 is used to impact the door panel 10 and align with the rolling guide device 20 to further ensure the rolling cooperation between the logistics trolley 300 and the rolling guide device 20.

[0059] In an optional example of this embodiment, a rubber layer is disposed on the outer side of the first buffer roller 30 and the outer side of the second buffer roller 310 .

[0060] Please refer to Figures 1 to 8 , the specific implementation process of the self-closing windproof door 100 proposed by the utility model and the logistics track system with the self-closing windproof door is now described in detail in conjunction with an embodiment.

[0061] In this embodiment, a logistics track system with self-closing windproof doors is installed in a hospital for the transportation of medical supplies.

[0062] The logistics track 200 is fixed above the self-closing windproof door 100. The logistics trolley 300 can move along the logistics track 200. The logistics trolley 300 is used for placing and transporting medical items. The self-closing windproof door 100 is installed on the wall of the isolation wall 400 through the self-closing two-way spring hinge 40. Through the self-restoring force of the self-closing two-way spring hinge 40, the self-closing windproof door 100 always remains closed or has a tendency to remain closed. The self-closing windproof door 100 can rotate bidirectionally relative to the wall. A first buffer roller 30 is installed at the center of the edge on the side (opening side) of the door panel 10 of the self-closing windproof door 100 away from the frame. The outer side of the first buffer roller 30 is a rubber layer. Two sets of rolling guide devices 20 are installed on the two opposite plate surfaces of the door panel 10. The rolling guide device 20 includes a buffer frame 21, a plurality of rolling guide members 22 and a plurality of telescopic shock-absorbing components 23. One end of the telescopic shock-absorbing component 23 is fixedly installed on the inner wall of the buffer frame 21, and the other end is fixed on the door panel 10. A number of rolling guide members 22 are installed on the buffer frame 21. The upper and lower ends of the rolling guide member 22 are rotatably connected to the buffer frame 21, and the force can be dissipated through the deformation and rotation of the buffer rolling guide member 22. Four second buffer rollers 310 are installed at the front and rear ends of the logistics trolley 300 respectively. The outer side of the second buffer roller 310 is a rubber layer. The installation height of the second buffer roller 310 is the same as the height of the corresponding rolling guide device 20, and the size of the second buffer roller 310 matches the size of the rolling guide member 22 of the rolling guide device 20.

[0063] During operation, the self-closing windproof door 100 is initially in a closed state. When the logistics trolley 300 approaches, the second buffer roller 310 first contacts the rolling guide device 20. Since the static friction force between the second buffer roller 310 and the rolling guide member 22 is greater than the self-restoring force of the self-closing two-way spring hinge 40, the rolling guide member 22 buffers and dissipates the force by rotating to the side. The sliding friction force between the logistics trolley 300 and the door panel 10 is converted into rolling friction force. Therefore, the self-closing windproof door 100 will be pushed open by the logistics trolley 300 and the second buffer roller 310, reducing the wear and damage caused by the impact of the logistics trolley 300 on the self-closing windproof door 100. The outer side of the second buffer roller 310 is made of rubber layer material, which further buffers the vibration between the logistics trolley 300 and the door panel 10 during operation. The second buffer roller 310 also uses the telescopic shock-absorbing component 23 of the rolling guide device 20 to buffer the vibration, further playing a role in shock absorption and noise reduction.

[0064] When the starting end of the logistics trolley 300 passes through the self-closing windproof door 100, under the action of the self-restoring force, the door panel 10 closes inward, and the contact point transfers from the second buffer roller 310 of the logistics trolley 300 to the first buffer roller 30 on the door panel 10. The first buffer roller 30 blocks the direct hard contact between the edge of the door panel 10 and the trolley, avoids damage to the door panel 10, extends the service life of the door panel 10, and converts the original sliding friction between the edge of the door panel 10 and the body of the logistics trolley 300 into rolling friction to buffer and unload the force.

[0065] When the logistics trolley 300 completely drives away from the self-closing windproof door 100, the door panel 10 returns to the initial position under the self-restoring action of the self-closing bi-directional spring hinge 40, realizing the automatic closing of the hole.

[0066] The self-closing windproof door 100 proposed by the present utility model and the logistics track system having the self-closing windproof door provide a safer, more efficient and more comfortable logistics transmission environment for hospitals, and further improve the quality and efficiency of medical services.

[0067] The self-closing windproof door 100 proposed by the present utility model effectively reduces the wear and damage caused by the impact of the logistics trolley 300 on the door panel 10, thereby extending the service life of the self-closing windproof door 100 and reducing the long-term maintenance cost; at the same time, the self-closing windproof door 100 effectively reduces the noise generated when the logistics trolley 300 passes through, reduces the noise level in the medical space, creates a quieter treatment and working environment for patients and medical staff, and improves the quality of medical services; in addition, the self-closing windproof door 100 provides effective shock absorption protection. Through the shock absorption structure design, it is ensured that the door panel 10 can withstand the impact of the logistics trolley 300, while protecting the structure of the door panel 10 from damage and reducing the maintenance requirements.

[0068] The logistics track system having the self-closing windproof door proposed by the present utility model can effectively isolate medical equipment from the external environment, effectively isolate the air circulation inside and outside the medical logistics channel, and greatly reduce the transmission risk of microorganisms such as bacteria and viruses, providing a solid guarantee for medical safety.

However, these descriptions cannot be construed as limitations on the present utility model for any reason. In particular, the various features described in different embodiments can be arbitrarily combined with each other to form other embodiments.
