Description

Technical Field

[0001] This utility model relates to the field of passageways in parks, squares, etc., and specifically to a suspended barrier-free self-service revolving door. Background Technology

[0002] my country's revolving door technology originated from imports from developed countries. In the late 1990s, revolving doors began to be rapidly promoted and widely used in my country's construction industry. With the continuous and stable growth of my country's national economy, the demand for doors has shifted from single-function to personalized and high-end. With its brand-new concept, spacious and open facade and high-profile design, revolving doors have gradually become one of the essential building facilities while meeting the needs of various groups of people to pass through.

[0003] Existing revolving doors on the market are mainly divided into manual and automatic types, with manual revolving doors primarily serving as pedestrian doors, employing a main rotating rod and rotating door wings. Existing revolving doors not only occupy a large area and are expensive, but some functions also fail to meet objective needs. Currently, revolving doors for wheelchair and stroller access are not fully functional. Furthermore, to further ensure the safety of visitors in parks, squares, and other public places, management departments have prohibited shared bicycles and electric bicycles from entering these areas. Based on these needs, there is an urgent need to develop a convenient revolving door that can both ensure the passage of wheelchairs and strollers and effectively prevent shared bicycles and electric bicycles from entering and causing pedestrian safety issues.

[0004] Chinese Patent Publication No. CN221346772U proposes an arc-shaped rotating convenient gate for wheelchairs and strollers to solve the above-mentioned problems. However, because this patent uses a ground-mounted pulley to rotate the arc-shaped rotating gate, the following problems exist: First, since the ground-mounted pulley used in this patent does not have a groove specifically set on the ground for installing limiting pulleys, the arc-shaped rotating gate in this patent has a large swaying amplitude and loud noise when rotating, which seriously shortens the service life of the gate. Second, since the intended users are wheelchairs or strollers, users of wheelchairs or strollers often extend their legs beyond the frame of the wheelchair or stroller. For example, when a patient in a wheelchair has a leg injury that prevents them from bending their legs, or when an infant / child is sitting in a stroller, their legs extend beyond the frame of the stroller. As a result, the arc-shaped rotating gate in this patent may cause the user's legs to get stuck when rotating.

[0005] In addition, existing patents require a perfectly flat ground surface for their ground rail pulleys, which places high demands on foundation treatment and increases foundation treatment costs. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a suspended barrier-free self-service revolving door to improve stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a suspended barrier-free self-service revolving door, including: a sliding rail assembly, an arc-shaped rotating gate, and a support assembly;

[0009] The support component includes two arc-shaped fixed fences spaced apart, wherein the space between the two arc-shaped fixed fences is on the same straight line;

[0010] The slide rail assembly includes an arc-shaped track and a pulley assembly disposed within the arc-shaped track. The pulley assembly is fixedly connected to the arc-shaped fixed fence. The arc-shaped track is arranged along two arc-shaped fixed fences. The arc-shaped rotating fence is disposed inside the arc-shaped track and is slidably connected to the pulley assembly through a connecting structure. It has an entrance / exit for pedestrians to pass through. The size of the entrance / exit is larger than the size of the space, and the bottom of the arc-shaped rotating fence has a ground clearance.

[0011] In some embodiments, a horizontal adjustment component is further included. The horizontal adjustment component is disposed at the bottom of the arc-shaped fixed fence. The horizontal adjustment component includes a horizontal short tube and an inner nut. The horizontal short tube is disposed on the bottom side of the arc-shaped fixed fence and partially inserted into the arc-shaped fixed fence. The inner nut is used to fix the horizontal short tube to the arc-shaped fixed fence.

[0012] In some embodiments, the connection structure includes an L-shaped upper flange, an L-shaped connector, and a lower flange connected sequentially from top to bottom. One side of the L-shaped connector is fixedly connected to the top outer side of the arc-shaped rotating fence, and the other side is fixedly connected to the inner side of the L-shaped upper flange. The lower flange is fixed to the outer side of the L-shaped upper flange and is slidably engaged with the pulley block.

[0013] In some embodiments, the pulley assembly includes a first pulley and a second pulley, the first pulley and the second pulley being slidably connected to the lower flange.

[0014] In some embodiments, the first pulley and the second pulley are both made of plastic-coated bearing pulleys, and the diameter of the first pulley and the second pulley is in the range of 3.2 to 3.6 cm.

[0015] In some embodiments, the ground clearance is 0.4 to 0.5 m.

[0016] In some embodiments, a vertical support tube is fixed inside the arc-shaped rotating fence, and a horizontal handrail is fixed on the vertical support tube.

[0017] In some embodiments, the diameter of the arc formed by the two arc-shaped fixed fences is 1.6m.

[0018] In some embodiments, the inner diameter of the arc-shaped rotating fence is 1.2m to 1.4m.

[0019] In some embodiments, the lower flange is made of a plasticized polymer material.

[0020] Furthermore, the beneficial effects of this utility model are as follows:

[0021] This utility model adopts a structure that combines an arc-shaped rotating fence with a sliding rail assembly, allowing the arc-shaped rotating fence to float relative to the arc-shaped fixed fence. This further frees up the space under the arc-shaped rotating fence, providing greater space for the entry and exit of extendable wheelchairs and strollers. Furthermore, the sliding rail assembly in this utility model effectively improves the stability of the arc-shaped rotating fence when rotating relative to the arc-shaped fixed fence through a sliding fit with the lower flange. At the same time, the sliding rail assembly uses plastic-coated bearing pulleys for the first and second pulleys, and the lower flange is made of plasticized polymer material, resulting in a higher fit between the two, better noise suppression, and smoother smoothness.

[0022] In the process of using this utility model, first align the entrance / exit of the arc-shaped rotating fence with the space between the arc-shaped fixed fence. After the wheelchair or stroller enters, rotate the horizontal handrail at the top of the arc-shaped rotating fence clockwise or counterclockwise. After rotating 180°, align the entrance / exit of the arc-shaped rotating fence with the other space between the arc-shaped fixed fence, and the wheelchair or stroller can drive out.

[0023] During use, the paint color of the curved convenience door can be changed according to the actual environment to suit more usage scenarios.

[0024] Meanwhile, this utility model only requires adjusting the leveling component during installation to achieve leveling, without the need for foundation treatment, thus saving investment and costs. Attached Figure Description

[0035] like Figure 1 - Figure 8As shown, this utility model provides a suspended barrier-free self-service revolving door, including: a sliding rail assembly, an arc-shaped rotating gate 1, and a support assembly;

[0036] The support assembly includes two arc-shaped fixed fences 2 spaced apart, wherein the space 8 formed between the two arc-shaped fixed fences 2 is on the same straight line;

[0037] The slide rail assembly includes an arc-shaped track 4 and a pulley assembly disposed within the arc-shaped track 4. The pulley assembly is fixedly connected to the arc-shaped fixed fence 2. The arc-shaped track 4 is disposed along two arc-shaped fixed fences 2. The arc-shaped rotating fence 1 is disposed inside the arc-shaped track 4 and is slidably connected to the pulley assembly through a connecting structure. It has an entrance / exit 3 for pedestrians to pass through. The size of the entrance / exit 3 is larger than the size of the interval space 8, and the bottom of the arc-shaped rotating fence 1 has a ground clearance.

[0038] The arc formed by the arc track 4 has a diameter of 1.6m and is made of stainless steel. Its cross-sectional dimensions are 10cm*10cm and its wall thickness is 0.5-0.7cm. In addition, the arc formed by the two arc-shaped fixed fences 2 has a diameter of 1.6m and is made of stainless steel. Its pipe diameter is 5-6cm and its wall thickness is 0.2-0.3cm.

[0039] One possible implementation also includes a horizontal adjustment component, which is located at the bottom of the arc-shaped fixed fence 2. The horizontal adjustment component includes a horizontal short pipe 10 and an inner nut 11. The horizontal short pipe 10 is located on the bottom side of the arc-shaped fixed fence 2 and is partially inserted into the arc-shaped fixed fence 2. The inner nut 11 is used to fix the horizontal short pipe 10 and the arc-shaped fixed fence 2. The horizontal short pipe 10 and the inner nut 11 are internally fixed to the bottom of the arc-shaped fixed fence. The pipe is made of stainless steel, with a diameter of 4 to 5 cm and a wall thickness of 0.15 to 0.25 cm. The nut is M40 to M50.

[0040] In this embodiment, the arc-shaped rotating fence 1 includes multiple vertically arranged vertical support tubes and multiple horizontal bars, wherein the vertical support tubes are made of stainless steel, with a diameter of 1.25m to 1.3m, a tube diameter of 3.2 to 3.8cm, and a wall thickness of 0.15 to 0.25cm.

[0041] In one possible implementation, the connection structure includes an L-shaped upper flange 12, an L-shaped connector 13, and a lower flange 14 connected sequentially from top to bottom.

[0042] In one possible implementation, the lower flange 14 is made of a plasticized polymer material, and the pulley system includes a first pulley 6 and a second pulley 7, which are slidably connected to the lower flange 14. Figure 5 As shown, the first pulley 6 and the second pulley 7 are stacked and form a gap in the middle to cooperate with the lower flange 14. At this time, the lower flange 14 slides inside the gap formed between the first pulley 6 and the second pulley 7. Meanwhile, the first pulley 6 and the second pulley 7 in this utility model are both made of plastic-coated bearing pulleys, and the diameter of the first pulley 6 and the second pulley 7 ranges from 3.2 to 3.6 cm. The slide rail assembly in this utility model effectively improves the stability of the arc-shaped rotating fence 1 when rotating relative to the arc-shaped fixed fence 2 through the sliding cooperation between it and the lower flange 14. At the same time, the slide rail assembly uses plastic-coated bearing pulleys for the first pulley 6 and the second pulley 7, and the lower flange 14 is made of plasticized polymer material, which makes the fit between the two higher, the noise suppression better, and the smoothness smoother.

[0043] Furthermore, in the above embodiments, the present invention provides a protective plate 9 at the opening of the arc-shaped track 4, wherein the surface of the protective plate 9 is provided with a rubber protective layer to prevent children and other users from inserting their fingers into the arc-shaped track 4.

[0046] In one possible implementation, the inner diameter of the arc-shaped rotating fence 1 is 1.2m to 1.4m. The arc-shaped rotating fence 1 is combined with the slide rail assembly to make the arc-shaped rotating fence 1 float relative to the arc-shaped fixed fence 2, which further frees up the space under the arc-shaped rotating fence 1 and provides greater space for the entry and exit of extendable wheelchairs and strollers.

[0047] The present invention will be further explained and illustrated below in conjunction with the actual working process.

[0048] Before using this utility model, it is necessary to adjust the gap between the first pulley 6, the second pulley 7 and the lower flange 14 according to the site size to ensure that the arc-shaped rotating fence 1 rotates smoothly. At the same time, the paint color of the arc-shaped rotating fence 1 should be selected according to the style of the surrounding environment.

[0049] In addition, the vertical support pipes and horizontal pipes in the arc-shaped rotating fence 1 have been welded and fixed before leaving the factory. At the same time, the L-shaped upper flange 12, flange, and L-shaped connector 13 have been fixed to the arc-shaped rotating fence 1. The first pulley 6 and the second pulley 7 have also been fixed inside the arc-shaped track 4. The horizontal adjustment components have also been fixed inside the arc-shaped fixed fence 2.

[0050] After being transported to the work site, the installation work began, specifically as follows:

[0051] 1. First, position the arc-shaped fixed fence 2 and the arc-shaped rotating fence 1. Adjust the plane position of the arc-shaped fixed fence 2 to a suitable position. Specifically, adjust the length of the horizontal short pipe 10 protruding from the arc-shaped fixed fence 2 to make the arc-shaped fixed fence 2 horizontal as a whole. Then, bury the arc-shaped fixed fence 2.

[0052] 2. Install the L-shaped upper flange 12 and lower flange 14 of the arc-shaped rotating fence 1 inside the arc-shaped slide rail, and make the above components slide in connection with the first pulley 6 and the second pulley 7;

[0053] 3. Weld all components securely.

[0054] After the above steps, the installation of this utility model is completed. In actual work, it is necessary to maintain the smoothness of the pulley in a timely manner according to the usage. When the pulley is obstructed, it should be replaced in time to ensure the normal rotation of the arc-shaped rotating fence assembly and meet the requirements of vehicle and pedestrian passage.

[0055] In the process of using this utility model, first align the entrance 3 of the arc-shaped rotating fence 1 with the space 8 of the arc-shaped fixed fence 2. After the wheelchair or stroller enters, rotate the horizontal handrail 5 on the upper part of the arc-shaped rotating fence clockwise or counterclockwise. After rotating 180°, align the entrance 3 of the arc-shaped rotating fence with the other space 8 of the arc-shaped fixed fence 2, and the wheelchair or stroller can drive out.

[0056] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
