DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] The utility model discloses an anti-pinch support arm structure, which mainly achieves the anti-pinch effect through structural improvement, which is beneficial to reduce the harm to the human body; the anti-pinch support arm structure is applied to a mattress, and a cotton pad is wrapped outside the frame formed by the anti-pinch support arm structure to form a mattress; Figures 1 to 3 The figure shows the application of the anti-pinch support arm structure in the head portion of a mattress; Figure 1 It is lying flat. Figure 2 It is in the rising state. Figure 3 It is assumed that when the mattress is switched from a raised state to a flat state, if there is an obstacle below (such as an infant crawling in), the anti-pinch arm structure will roll up in the opposite direction to avoid causing harm to the infant.

[0034] like Figures 4 to 6 As shown, an anti-pinch arm structure includes a plurality of coupled movable joints 1; a first connection portion is provided at one end of the movable joint 1, and a second connection portion is provided at the other end of the movable joint 1; in two adjacent movable joints 1, the first connection portion of one movable joint 1 is connected to the second connection portion of the other movable joint 1; the first connection portion is provided with a first limiting member 101, and the second connection portion is correspondingly provided with a second limiting member 102; the first limiting member 101 includes a first assembly cylinder 1012 located in the middle, and the second limiting member 102 includes a second assembly cylinder 1022 located in the middle, when the adjacent movable joints 1 are as shown in FIG. Figure 4 When assembled together as shown, the second assembly cylinder 1022 is embedded in the first assembly cylinder 1012, and both the second assembly cylinder 1022 and the first assembly cylinder 1012 are hollow. At this time, bolts are installed horizontally in the hollow to rotate and fix the adjacent movable joints 1 together.

[0035] In addition, a first sinker 1013 is provided at the corresponding position of the first assembly cylinder 1012, and a second sinker 1023 is provided at the corresponding position of the second assembly cylinder 1022. The sinker, that is, this part, is lower than the side surface of the movable joint 1. Since one end of the bolt has a bolt head and the other end of the bolt is fixed by screwing in a nut, the first sinker 1013 and the second sinker 1023 are used to hide the bolt head and the nut. The bolt head and the nut are as flush as possible with the side surface of the movable joint 1 to reduce scratches on the wrapped cotton pad.

[0036] Two anti-pinch arm structures of the same specification are used in a mattress. The two anti-pinch arm structures are arranged correspondingly, with the inner sides facing inwards, and a row of frames is transversely connected between the two anti-pinch arm structures; a frame installation insertion position 104 is provided on the inner side of the movable joint 1, and the frame installation insertion position 104 is for inserting and installing the row of frames; Figure 4 It can be seen that the frame installation insertion position 104 is a frame-shaped protrusion, which has a limiting effect on the slat frame, so that the slat frame is not easy to be separated after being pressed after being inserted; after the slat frame is fixed, the cotton pad is wrapped. The upper and lower surfaces of the movable joint 1 are both flat, which is conducive to the flat wrapping of the cotton pad.

[0037] The second limiting member 102 surrounds a limited activity space 103. When blocked by external force (i.e. encountering an obstacle during descent), the first limiting member 101 can rotate in the limited activity space 103, and the rotating surface of the first limiting member 101 intersects with the second limiting member 102, that is, the first limiting member 101 will be limited by the second limiting member 102 after rotating at a certain angle, so that the movable joints 1 connected in sequence can all rotate.

[0038] The first limiting member 101 includes a clamping plate 1011 . When two adjacent movable joints 1 rotate relative to each other, the clamping plate 1011 of one movable joint 1 rotates in the limited movable space 103 of the other movable joint 1 .

[0039] The second limiting member 102 includes a fan-shaped boss 1021, and the limited activity space 103 is clamped between the fan-shaped bosses 1021; in the present embodiment, there are two clamping plates 1011, and the two clamping plates 1011 are symmetrically connected to the first assembly tube 1012; there are also two fan-shaped bosses 1021, which are clamped to form two limited activity spaces 103, and the clamping plates 1011 correspond one to one to the limited activity spaces 103.

[0040] The two sides of the fan-shaped boss 1021 are formed with blocking side surfaces 10211, wherein the blocking side surface 10211 on one side restricts the card plate 1011 from further rotating clockwise, and the blocking side surface 10211 on the other side restricts the card plate 1011 from further rotating counterclockwise. The purpose of the above restriction is that only by restricting the card plate 1011 from further rotating to one side can the following be formed: Figure 1 as well as Figure 2 The purpose of the whole page lifting is to limit the continued rotation of the card plate 1011 to the other side, so as to form the following Figure 3 As shown, when one or more active joints 1 encounter an obstacle, a series of reverse rotations will occur, that is, the series of active joints 1 connected have a chain reaction.

[0041] Combination Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, when the movable joint 1 is in a flat state, the card plate 1011 is arranged horizontally, that is, the card plates 1011 on both sides are arranged symmetrically up and down on the horizontal line; the movable joint 1 has a critical edge 1014, and the adjacent movable joints 1 are used in combination and when one of the movable joints 1 is rotated clockwise to the maximum angle, the critical edge 1014 is located at the intersection of the upper surfaces of the two; the angle between the blocking side 10211 used to limit the further rotation of the card plate 1011 and the horizontal line is set to α, and the angle between the critical edge 1014 and the horizontal line is set to β, then β>α, the purpose of the above design is that when the card plate 1011 is rotated to the angle α, it is limited and will not rotate further clockwise, so as to avoid the critical edge 1014 from being compressed and damaged; the value range of α is 10~70°, which can be set according to actual needs. In this embodiment, α is set to 70°.

[0042] Combination Figure 7 as well as Figure 8 In this embodiment, the number of the fan-shaped bosses 1021 and the card plate 1011 are both two, and the blocking side surface 10211 located above the lower fan-shaped boss 1021 and the blocking side surface 10211 located below the upper fan-shaped boss 1021 jointly limit the card plate 1011 to rotate counterclockwise, so that the whole anti-clamping support arm structure is as shown in FIG. Figure 1 As shown in the figure, it can lie flat and the end can be stressed as Figure 2 The entire page shown is lifted; from Figure 8 It can be seen that the blocking side 10211 located at the bottom of the lower fan-shaped boss 1021 and the blocking side 10211 located at the top of the upper fan-shaped boss 1021 jointly limit the card plate 1011 to rotate clockwise, so that when the anti-pinch arm structure is subjected to external force (such as pressing on a child), the connected movable joint 1 will rotate away from the child, and the movable joint 1 is driven to rotate in turn to form a wrapping shape, which will not crush the child.

[0043] like Figure 5As shown, the first connecting portion is recessed to form an arc position 105, and the second connecting portion is protruding to form a round head position 106. When adjacent movable joints 1 are connected, the round head position 106 is embedded and assembled in the arc position 105, and the round head position 106 and the arc position 105 are rotatably assembled. The structure is compactly combined and the effect of embedded foreign matter on rotation is reduced.

[0044] The rotations mentioned above are all relative, that is, the first limiting member 101 rotates relatively in the limited activity space 103. It is possible that the second limiting member 102 is stationary and the first limiting member 101 rotates; it is also possible that the first limiting member 101 is stationary and the second limiting member 102 rotates.

[0045] The major improvement of the anti-pinch arm structure is that the combined use of the first limiting member 101 and the second limiting member 102 allows the adjacent movable joints 1 to have a certain angle of rotation limit. When switching from a raised state to a flat state, if there is an obstacle below, especially when the obstacle is an infant, the first limiting member 101 and the second limiting member 102 will rotate relative to each other, so that the movable joints 1 will be rolled up in the opposite direction of the obstacle in turn, avoiding crushing injuries to the infant, and also protecting the anti-pinch arm structure itself.

[0046] like Fig. 9 As shown, the utility model also requests protection for a mattress, including the anti-pinch arm structure described in any of the above items, the anti-pinch arm structure composed of a plurality of movable joints 1 is applied to the head and foot parts of the bed, so that the mattress has an anti-pinch function; when packaging, the movable joints 1 on both sides of the head and tail can also be folded in half and rolled up to put into a carton with a small volume, which is convenient and quick to go up and down the stairs and enter the house.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
