Description

Technical Field

[0001] The present application relates to the field of guardrails, and in particular to a child guardrail. Background Art

[0002] At present, in some large shopping malls or parks, sand pools are often set up for children to play. In order to ensure the safety of children's games and avoid bumps, a circle of guardrails are usually set up around the sand pool.

[0003] At present, common guardrails mainly include plastic guardrails, wooden guardrails, inflatable guardrails, etc., with plastic guardrails being the most common. This type of plastic guardrail is often made up of several unit guardrails, which are usually hollow structures with light weight and are easy to collapse due to impact. They are not reliable to maintain and have poor protection effects. Summary of the invention

[0004] In order to increase the reliability of guardrail protection, the present application provides a child guardrail.

[0005] The child guardrail provided in this application adopts the following technical solution:

[0006] A child guardrail comprises a plurality of unit guardrails connected end to end, each of the unit guardrails is provided with an inlet for injecting a flowing substance, and the interior of the unit guardrails is enclosed to form a closed space for accommodating the flowing substance.

[0007] By adopting the above technical solution, flowing material is injected into each unit guardrail to increase the mass of each unit guardrail, so as to enhance the overall stability of the child guardrail of the present application. Due to its large mass, it is not easy to tilt when it is windy or hit, and the protective effect is better.

[0008] Preferably, each of the unit guardrails includes a main body, a first connecting member installed on one side of the main body, and a second connecting member installed on the opposite side of the first connecting member, and the first connecting member and the second connecting member of two adjacent main bodies are plugged into each other to achieve end-to-end connection.

[0009] By adopting the above technical solution, by connecting the first connecting piece of a unit guardrail with the second connecting piece of an adjacent unit guardrail by plugging, it is easy to connect two adjacent unit guardrails, and the connection is more convenient.

[0010] Preferably, the first connecting member and the second connecting member are staggered along the height direction of the main body portion, and the first connecting member and the second connecting member are plugged in up and down.

[0011] By adopting the above technical solution, the connection is not only convenient through the form of up and down plugging, but also convenient for limiting the left and right movement of two adjacent unit guardrails, and the connection is relatively stable.

[0012] Preferably, the first connector includes a first connector and a latch installed at the bottom of the first connector, and the second connector includes a second connector and a socket opened at the top of the second connector for inserting the latch.

[0013] By adopting the above technical solution, the pin is set at the top and the socket is set at the bottom. During installation, the pin is controlled to be gradually inserted into the socket from top to bottom, which is convenient for observing the alignment of the pin and the socket during plugging, facilitating one-time plugging in place and making the operation more convenient.

[0014] Preferably, the unit guardrail is also provided with a positioning component for adjusting and positioning the connection angle between the unit guardrails.

[0015] By adopting the above technical solution, the positioning component can limit the connection angle between two adjacent unit guardrails, avoiding the axial rotation of the pin in the socket, which causes the relative position between the two adjacent unit guardrails to shift.

[0016] Preferably, the positioning assembly includes a positioning pin installed on the side wall of the plug, and the top of the second connector is provided with a positioning recess for the positioning pin to be embedded.

[0017] Through the above technical solution, the positioning pin is inserted into the positioning groove, which can limit the axial rotation of the pin.

[0018] Preferably, a plurality of the positioning recesses are spaced apart around the axis of the insertion hole, and the positioning pin is used to be inserted into different positioning recesses according to the connection angle.

[0019] By adopting the above technical solution, it is convenient to insert the positioning pins into different positioning grooves according to the different connection angles of the unit guardrails, so that there are multiple connection angles between two adjacent unit guardrails to adapt to different connection scenarios.

[0020] Preferably, the angle between each of the positioning grooves and a horizontal line connecting the first connecting member and the second connecting member is configured to be a specific angle.

[0021] By adopting the above technical solution, it is easier to quickly adjust the connection angle between two unit guardrails.

[0022] Preferably, the main body portion includes a base and a frame integrally formed above the base, and a glass window for observation is embedded in the frame.

[0023] By adopting the above technical solution, installing glass windows makes it convenient for parents to observe the situation of children inside the guardrail, and also makes it convenient for children to observe the situation of parents outside.

[0024] Preferably, the frame is configured to be in an arch shape, and the thickness of the base is greater than the thickness of the frame.

[0025] By adopting the above technical solution, after injecting the flowing material, the mass of the base is greater, making the bottom of the unit guardrail more stable and the overall anti-tilting ability better. The arched frame has a smooth edge shape, which is not easy to scratch or hit children. It has a beautiful appearance and is safer.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The present application increases the mass of the unit guardrail by injecting flowing material into the original hollow unit guardrail, thereby improving the overall wind resistance and anti-tilting performance of the child guardrail and increasing the overall protective effect of the child guardrail;

[0028] 2. By arranging a first connecting piece and a second connecting piece on both sides of each unit guardrail for realizing the vertical plugging of two adjacent unit guardrails, the assembly between the unit guardrails is more convenient, and it is convenient to limit the left and right movement of the unit guardrails;

[0029] 3. Through the cooperation of positioning pins and positioning grooves, the connection angles between unit guardrails can be adjusted and limited. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The present application embodiment discloses a child guardrail. Figure 1The child guardrail includes a plurality of unit guardrails 1 connected end to end. Each unit guardrail 1 is provided with an inlet 2 for injecting a flowing substance, and the interior of each unit guardrail 1 is enclosed to form a closed space for accommodating the flowing substance. When in use, water, sand or other flowing substances are poured into the interior of each unit guardrail 1, so that the weight of the unit guardrail 1 is increased, and the probability of tilting due to impact is reduced, thereby increasing the protection stability and protection safety of the guardrail.

[0037] Reference Figure 4 After the interior of the unit guardrail 1 is filled with flowing materials such as water or sand, the inlet 2 is blocked with the sealing plug 3. Specifically, the sealing plug 3 includes a threaded plug body 31 and a knob 32 fixedly connected to one end of the threaded plug body 31. The diameter of the screw is larger than the diameter of the threaded plug body 31 to completely block the inlet 2. Furthermore, in order to increase the sealing effect of the sealing plug 3, a rubber plug 33 is fixedly connected to the side of the knob 32 close to the threaded plug body 31.

[0038] The distance between the inlet 2 and the bottom of the unit guardrail 1 directly affects the amount of fluid material contained in the unit guardrail 1. Therefore, the present application sets the inlet 2 at the upper part of the unit guardrail 1 to contain more fluid material in the unit guardrail 1. An outlet is also provided at the lower part of the unit guardrail 1 to facilitate the discharge of the fluid material inside when the guardrail is removed, so as to facilitate the storage of the guardrail. The outlet is also blocked with a sealing plug 3.

[0039] Reference Figure 1 and Figure 2 Each unit guardrail 1 includes a main body 4, a first connecting member 5 installed on one side of the main body 4, and a second connecting member 6 installed on the side of the main body 4 opposite to the first connecting member 5. The first connecting member 5 and the second connecting member 6 of two adjacent main bodies 4 are connected to achieve the end-to-end connection of several unit guardrails 1. In order to facilitate the assembly of the unit guardrails 1, the first connecting member 5 of one unit guardrail 1 is connected to the second connecting member 6 of the adjacent unit guardrail 1 by plugging.

[0040] Reference Figure 2 In order to ensure the connection stability between the first connector 5 and the second connector 6, the first connector 5 and the second connector 6 are staggered along the height direction of the main body 4, so that the first connector 5 and the second connector 6 can be plugged in up and down to limit the horizontal movement of two adjacent unit guardrails 1. And the up and down plugging method is more convenient for installation.

[0041] Reference Figure 2, the present application takes the example of setting the first connecting member 5 at the upper part of the main body 4 and setting the second connecting member 6 at the lower part of the main body 4 for explanation. The first connecting member 5 includes a first connecting body 51 and a plug 52 fixedly mounted at the bottom of the first connecting body 51. The second connecting member 6 includes a second connecting body 61 and a socket 62 provided at the top of the second connecting body 61 for the plug 52 to be inserted. During installation, the plug 52 can be inserted into the socket 62 by moving it from top to bottom, and this arrangement makes it easy to observe the alignment of the plug 52 and the socket 62.

[0042] Reference Figure 1 Generally speaking, the positions of the inlet 2 and the outlet can be set arbitrarily, as long as there is a height difference between the inlet 2 and the outlet. However, considering that children may be curious about the structure on the guardrail when playing, if the sealing plugs 3 of the inlet 2 and the outlet are set in an easily visible position, children are very likely to pull out the sealing plugs 3 driven by curiosity, causing the internal flowing material to flow out, causing unnecessary harm to the children. Therefore, the present application preferably sets the inlet 2 on the same side as the second connecting member 6 and above the first connecting member 5. The outlet is set at the bottom of the main part 4, and a sink groove for screwing and embedding is set at the bottom of the outlet so that the top surface of the screw does not protrude from the bottom surface of the main part 4. After installation, the two adjacent unit guardrails 1 clamp the sealing plug 3 at the inlet 2 position in the middle, which is not easy to be observed. This is to reduce the probability of pulling out the sealing plug 3 when children play, causing the flowing material such as water or sand inside the unit guardrail 1 to flow out.

[0043] Reference Figure 2 and Figure 3 Since the present application uses a latch 52 for connection, and the latch 52 is usually cylindrical, in order to limit the axial rotation of the latch 52 in the socket 62, thereby causing the preset angle between two adjacent unit guardrails 1 to change, a positioning component 7 for adjusting and positioning the connection angle between the unit guardrails 1 is also provided on each unit guardrail 1.

[0044] In a specific structural embodiment, the positioning assembly 7 includes a positioning pin 71 fixedly mounted on the side wall of the latch 52, and a positioning recess 72 for the positioning pin 71 to be embedded is provided on the top of the second connector 61. When the latch 52 is inserted, the positioning pin 71 is aligned with and embedded in the positioning recess 72 to limit the axial rotation of the latch 52. The positioning pin 71 is fixed, and the positioning pin 71 can extend along the axial direction of the latch 52 or can be a block fixedly mounted on one side of the latch 52 close to the first connector 51. The depth of the positioning recess 72 is set according to the shape of the positioning pin 71. The present application only takes the positioning pin 71 as a block fixedly mounted on one side of the latch 52 close to the first connector 51 as an example for explanation.

[0045] Reference Figure 3 Furthermore, a plurality of positioning grooves 72 are arranged at intervals around the axis of the insertion hole 62, and the positioning pin 71 is used to be inserted into different positioning grooves 72 according to the connection angle between two adjacent unit guardrails 1. That is, by controlling the positioning pin 71 to be inserted into different positioning grooves 72, two adjacent unit guardrails 1 can form different angles to adapt to different scenarios.

[0046] Preferably, the angle between each positioning groove 72 and the horizontal line connecting the first connector 5 and the second connector 6 is configured to be a specific angle. For example, 0 degrees, 30 degrees, 35 degrees, 60 degrees, 90 degrees, etc., to adapt to the connection in conventional scenarios. The number of positioning grooves 72 can be set accordingly according to conventional connection scenarios. This application only takes the example that three positioning grooves 72 are provided, and the angles between the positioning grooves 72 and the horizontal line connecting the first connector 5 and the second connector 6 are 0 degrees, 45 degrees and 90 degrees respectively.

[0047] In another specific structural embodiment, the positioning component 7 can also be a hanging ring (not shown in the figure) and a hook (not shown in the figure) respectively arranged on both sides of the main body 4. When two adjacent unit guardrails 1 are connected and set to a preset angle, the hook is hung in the hanging ring to fix the relative position of the two adjacent unit guardrails 1.

[0048] In order to adapt to the connection angle between the unit guardrails 1, the first connector 51 and the second connector 61 are both cylindrical, and the smooth transition shape is conducive to reducing the damage to children when bumping.

[0049] The main body 4 includes a base 41 and a frame 42 integrally formed above the base 41. A glass window 8 for observation is embedded in the outward side of the frame 42. This allows children to observe the outside and parents to observe the status of their children. The frame 42 is provided with a circle of embedding grooves 421 for the glass window 8 to be embedded, and embedded parts 422 for fixing the glass window 8 are embedded in the embedding grooves 421.

[0050] Reference Figure 2 and Figure 3 Furthermore, the shape of the frame 42 is designed to be an arch, and the thickness of the base 41 is greater than the thickness of the frame 42, which not only makes the unit guardrail 1 more beautiful as a whole, but also makes the structure more stable and the protection more reliable. The frame 42 is designed to be an arch, so that the edges of the frame 42 are all smooth, not easy to scratch or hit children, and more secure.

[0051] The implementation principle of a child guardrail in an embodiment of the present application is as follows: during installation, first move the first unit guardrail 1 to the predetermined installation position, inject water or sand from the inlet 2 position, inject it to the height of the inlet 2, and use the sealing plug 3 to seal the inlet 2 tightly. Then take another unit guardrail 1, align the pin 52 of the first connecting member 5 on the unit guardrail 1 with the socket 62 of the second connecting member 6 on the first unit guardrail 1 and insert it. When inserting, according to the required connection angle of the two adjacent unit guardrails 1, insert the positioning pin 71 into the corresponding positioning groove 72 to complete the connection. After the connection is completed, inject water or sand into the second unit guardrail 1. Enclose the child guardrails of the present application in sequence.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
