[0001] The utility model relates to a guardrail, in particular to a novel folding child guardrail. Background Art

[0002] With the improvement of living standards, maternal and child products are emerging in an endless stream. Since babies can easily fall to the ground in bed, there will be safety hazards, so adults like to put up a guardrail beside the bed. For example, the publication number is CN104116347B, and the name is called "A foldable bed guardrail". The folding guardrails on the market are currently complex in structure, and basically use a snap-on opening method, which has a certain learning cost and is not structurally reliable. How to create a new type of guardrail folding method is the technical problem we need to solve now. Utility Model Content

[0025] like Figure 1-Figure 10 As shown, a novel foldable child guardrail includes a fixing seat 100 for installation at the side of a bed, and also includes a support rod 200 connecting the two fixing seats 100 and forming a protective surface by installing a cloth surface. The two ends of the support rod 200 are rotatably connected to the two fixing seats 100 respectively, and elastic devices 300 are provided on the outer sides of the two ends of the support rod 200 and relative to the positions of the fixing seats 100. The fixing seats 100 are provided with a plurality of limiting grooves 110 for limiting the elastic devices 300. The support rod 200 switches the position of the limiting grooves 110 by the elastic devices 300 to achieve angle limitation with the fixing seats 100. The cloth surface can be made of Oxford cloth or other materials that are easy to clean and have reliable strength. Since there are a plurality of limiting grooves 110, the elastic devices 300 are used to switch the limiting grooves 110 to achieve the conversion between the supporting state and the folding state. The specific usage method is shown below.

[0026] The elastic device 300 includes an outer sleeve 310 sleeved on the outer side of the support rod 200, and the outer sleeve 310 has a reciprocating motion path along the axial direction of the support rod 200. The outer sleeve 310 is provided with a protrusion 311 that matches the limiting groove 110. The outer sleeve 310 and the fixing seat 100 are inserted into the limiting groove 110 through the protrusion 311 to achieve angle limitation. The support rod 200 and the fixing seat 100 are rotationally matched, so the rotation limitation of the support rod 200 is achieved by inserting the protrusion 311 into the limiting groove 110.

[0027] The support rod 200 is provided with a fixing pin 210 for limiting the outer sleeve 310, and the outer sleeve 310 is provided with a limiting hole 312 that cooperates with the fixing pin 210. The outer sleeve 310 realizes limited reciprocating motion on the support rod 200 through the cooperation between the fixing pin 210 and the limiting hole 312. The cooperation between the fixing pin 210 and the limiting hole 312 enables the outer sleeve 310 to have a stroke control outside the support rod 200.

[0028] The outer sleeve 310 is provided with a spring structure 320 for preventing the protrusion 311 from escaping from the limiting groove 110. The present application preferably adopts the spring structure 320, which is easy to assemble and has low cost. Without the spring structure 320, the elastic device 300 can be manually inserted into the limiting groove 110. By adding the spring structure 320, the elastic device 300 is always pushed in the direction of the limiting groove 110, and has an automatic snap-in function, which is more convenient.

[0029] An inner sleeve 330 for cooperating with the spring structure 320 is provided between the outer sleeve 310 and the support rod 200 . The inner sleeve 330 is fixedly connected to the outer side of the support rod 200 through a fixing pin 210 . The function of the inner sleeve 330 is to cooperate with the spring structure 320 .

[0030] The fixing seat 100 is provided with a guide groove 120 for the support rod 200 to rotate with, and the number of the limiting grooves 110 is two groups, which are respectively called the first group of grooves 111 and the second group of grooves 112. The number of the two groups of limiting grooves 110 is two and they are respectively arranged in the guide groove 120 and at the two sides relative to the support rod 200. The first group of grooves 111 and the second group of grooves 112 are distributed one above and one below. The support rod 200 forms a folding angle of 180 degrees through the cooperation of the first group of grooves 111 and the second group of grooves 112. There are many ways to set the number of groups of limiting grooves 110, such as setting three groups, namely, upper, lower and front. The support rod 200 also has an angle limit parallel to the bed surface. The present application preferably adopts a two-group structure, one is to allow the support rod 200 to be stretched upward to form a guardrail, and the other is to be directly folded downward for storage.

[0031] The outer sleeve 310 is provided with a handle portion 313 for conveniently pulling the outer sleeve 310 . The handle portion 313 is provided to facilitate moving the outer sleeve 310 with human hands.

[0032] The two fixing seats 100 are fixedly connected by a connecting rod 130. The fixing seats 100 are provided with an installation groove 140 for installing the connecting rod 130. The two fixing seats 100 are fixedly assembled by the cooperation between the connecting rod 130 and the installation groove 140 and in a snap-fit ​​manner. The addition of the connecting rod 130 improves the overall structural stability of the guardrail. The connecting rod 130 and the support rod 200 can be a combined structure in the form of multiple rod sockets, which will also fall within the protection scope of this application.

[0033] On the fixed seat 100 and on one side relative to the support rod 200, there is a fixed rod 150 extending towards the carrier. On the fixed seat 100, there is a card slot 160 that cooperates with the fixed rod 150. The fixed rod 150 is fixed and limited to the fixed seat 100 through the card slot 160. The fixed rod 150 can be fixedly connected to the card slot 160 by means of riveting or screwing. Here, the carrier refers to a bed. The fixed rod 150 is mainly used to be placed between the mattress and the bed board. The gravity of the mattress itself and the weight of the human body prevent the guardrail from tilting sideways. A non-slip silicone pad 151 can also be provided at the front end of the fixed rod 150 to improve the reliability of the fixed seat 100.

[0034] The cross-section of the support rod 200 is a U-shaped structure. The support rod 200 is preferably of a U-shaped structure, which is convenient for covering with a cloth surface. The support rod 200 is not strictly a "U" shape. As can be seen from the drawings, large-diameter chamfers can be used at the two corners to reduce the risk of collision.

[0035] Usage method:

[0036] In the support state, the support rod 200 stands upright upwards to撑开 the cloth surface to form a guardrail. At this time, the elastic device 300 is located above the fixed seat 100 along with the support rod 200, as Figure 1 shown;

[0037] When folding is required, pull the outer sleeve 310 upwards to make the convex block 311 of the outer sleeve 310 leave the limit groove 110. Then the support rod 200 can be rotated. When the support rod 200 is rotated to the bottom position, the convex block 311 of the outer sleeve 310 is inserted into the limit groove 110 at the bottom of the fixed seat 100, completing the conversion from the support state to the folded state. The folded state is convenient for people to get on and off, as Figure 4 shown.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, simple modifications and substitutions by ordinary technicians in the field are within the protection scope of the present invention.
