The connecting tube one is fixedly connected to the surface of the U-shaped tube located on the right side, and the connecting tube two is fixedly connected to the surface of the U-shaped tube located on the left side. The connecting tube one is disposed on the outer surface of the connecting tube two. An elastic plate is fixedly connected to the end of the connecting tube one away from the surface of the U-shaped tube. A protrusion is fixedly connected to the side of the elastic plate away from the center of the connecting tube one. A pressure claw is fixedly connected to the side of the elastic plate close to the center of the connecting tube one. A threaded groove is provided on the surface of the connecting tube one, and the threaded sleeve is threadedly connected to the surface of the threaded groove. An inclined surface is provided on the inner wall of the threaded sleeve.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a fall prevention device for osteoporosis in the elderly, comprising a U-shaped tube 1. The number of U-shaped tubes 1 is set to two sets. The bottom of one set of U-shaped tubes 1 is fixedly connected to a left support leg 2, and the bottom of the other set of U-shaped tubes 1 is fixedly connected to a right support leg 3. The two sets of U-shaped tubes 1 form a symmetrical structure through the left support leg 2 and the right support leg 3, which enhances the overall stability of the device. The U-shaped tube 1, the left support leg 2, and the right support leg 3 cooperate with each other to provide basic support force, preventing the elderly from accidentally falling due to unstable ground. There are two left support legs 2 and two right support legs 3. The two left support legs 2 are fixedly connected to each other through a reinforcing rod 4, and the two right support legs 3 are fixedly connected to each other through a reinforcing rod 4. The fixed connection through the reinforcing rod 4 improves the elderly's ability to resist lateral tilting when using the device.

[0033] Reference Figures 2-4 A guide mechanism 10 is provided at the bottom of the U-shaped tube 1, and an adjustment mechanism 11 is provided on the surface of the U-shaped tube 1. The adjustment mechanism 11 includes a first connecting tube 111, a second connecting tube 112, and a threaded sleeve 116. The first connecting tube 111 is fixedly connected to the surface of the U-shaped tube 1 on the right side, and the second connecting tube 112 is fixedly connected to the surface of the U-shaped tube 1 on the left side. The first connecting tube 111 is sleeved on the outer surface of the second connecting tube 112. An elastic sheet 113 is fixedly connected to the end of the first connecting tube 111 away from the surface of the U-shaped tube 1. The elastic sheet 113 is made of elastic spring steel. When the elastic sheet 113 is subjected to external force, it will undergo elastic deformation. When the elastic sheet 113 is not subjected to external force, it is in a naturally extended straight state.

[0034] Reference Figures 3-5A protrusion 114 is fixedly connected to the side of the elastic sheet 113 away from the center of the connecting tube 111. The cross-sectional shape of the protrusion 114 is semi-circular. A pressure claw 115 is fixedly connected to the side of the elastic sheet 113 near the center of the connecting tube 111. The side of the pressure claw 115 away from the elastic sheet 113 is provided with anti-slip texture. The pressure claw 115 contacts the surface of the connecting tube 112 through the anti-slip texture, increasing the friction between the pressure claw 115 and the connecting tube 112, thereby achieving relative displacement locking between the connecting tube 112 and the connecting tube 111 during use. The surface of the connecting tube 111 is provided with threads. The groove 117 and the threaded sleeve 116 are threadedly connected to the surface of the threaded groove 117. The helix angle of the threaded groove 117 is less than the equivalent friction angle between the tooth surfaces, so that when the threaded sleeve 116 and the threaded groove 117 are engaged, the threaded sleeve 116 will not move due to changes in load. When the threaded sleeve 116 rotates, it will also move in the radial direction of the connecting pipe 111. The inner wall of the threaded sleeve 116 is provided with an inclined surface 118, which engages with the protrusion 114. When the inclined surface 118 presses against the protrusion 114, the elastic sheet 113 deforms, which drives the pressure claw 115 to move.

[0035] Reference Figure 1 and Figure 2 The guiding mechanism 10 includes a first connecting rod 101 and a second connecting rod 102. The top of the first connecting rod 101 is hinged to the surface of the right support leg 3, and the top of the second connecting rod 102 is hinged to the surface of the left support leg 2. The middle part of the first connecting rod 101 is hinged to the middle part of the second connecting rod 102, forming an X-shaped structure. When the distance between the left support leg 2 and the right support leg 3 changes, the included angle between the first connecting rod 101 and the second connecting rod 102 also changes, thereby driving the slider 103 to slide in the groove 104, guiding the support legs to open and close smoothly and avoiding unilateral tilting. The end of the first connecting rod 101 away from the right support leg 3 and the end of the second connecting rod 102 away from the left support leg 2 are both hinged with sliders 103. The surfaces of the left support leg 2 and the right support leg 3 are both provided with grooves 104. The sliders 103 are slidably connected to the inner wall of the groove 104 to ensure the stability of the equipment during dynamic use (such as when the elderly walk or sit down) and reduce the risk of falling due to shaking.

[0036] Reference Figure 1 and Figure 2The guiding mechanism 10 also includes a fixed rod 105 and a guide rod 106. The fixed rod 105 is fixedly connected to the surface of the right support leg 3, and the guide rod 106 is fixedly connected to the surface of the left support leg 2. The guide rod 106 is slidably connected to the inner wall of the fixed rod 105. The inner diameter of the first connecting tube 111 and the outer diameter of the second connecting tube 112 are equal to ensure that the left support leg 2 and the right support leg 3 move in the horizontal direction, improving the adjustment accuracy. When the threaded sleeve 116 rotates, the threaded sleeve 116 presses the elastic piece 113 through the inclined surface 118. The inclined surface 118 pushes the protrusion 114 to bend the elastic piece 113, which drives the pressure claw 115 to clamp the second connecting tube 112, fixing the adjusted width. The thread self-locking is used to maintain the fixed state and prevent loosening during use.

[0037] Working principle: During use, the elderly person rotates the threaded sleeve 116 of the adjustment mechanism 11 according to their gait width. The threaded sleeve 116 moves to the left along the threaded groove 117 towards the left support leg 2 (the entire text refers to this direction). Figure 1 (As shown in the center direction), so that the inclined surface 118 of the inner wall of the threaded sleeve 116 disengages from the contact protrusion 114. At this time, the pressure claw 115 on the surface of the elastic piece 113 no longer clamps the connecting tube 2 112, which allows the connecting tube 111 and the connecting tube 2 112 to slide relative to each other. Adjust the two sets of U-shaped tubes 1 to a suitable width (such as a narrower spacing for indoor walking and a wider spacing for outdoor uneven surfaces). Then rotate the threaded sleeve 116 in the opposite direction, so that the inclined surface 118 of the inner wall of the threaded sleeve 116 presses against the protrusion 114, forcing the elastic piece 113 to bend towards the center of the connecting tube 111, driving the pressure claw 115 to tighten and clamp the connecting tube 2 112. At this time, the distance between the left and right U-shaped tubes 1 is fixed.

[0038] After adjustment, the pressure claw 115 is in close contact with the connecting tube 112 through the anti-slip texture. Combined with the self-locking characteristics of the threaded sleeve 116, it ensures that the equipment will not loosen or change spacing due to external forces (such as collisions or uneven ground) during use. When the elderly walk, the left support leg 2 and the right support leg 3 are connected by the guide mechanism 10 and the rigid connection of the reinforcing rod 4, providing wide base support, lowering the center of gravity height, and improving the ability to resist falls. It is suitable for use by elderly patients with osteoporosis in slippery scenarios such as bathrooms and corridors.

[0039] After use, when it is time to store, rotate the threaded sleeve 116 so that the inclined surface 118 of the inner wall of the threaded sleeve 116 disengages from the contact protrusion 114, thereby releasing the pressure of the elastic plate 113 and allowing the connecting tube 111 and the connecting tube 212 to slide relative to each other. At this time, adjust the two sets of U-shaped tubes 1 to the minimum width to minimize the overall footprint of the device, making it convenient for small-sized families to store and move, thus improving its practicality.

[0040] Based on the above work, when the distance between the two sets of U-shaped tubes 1 changes, connecting rod 101 and connecting rod 2 102 rotate around the hinge point, thereby causing the slider 103 to slide in the slide groove 104. At the same time, the guide rod 106 moves horizontally in the fixed rod 105. Through the cooperation of connecting rod 101 and connecting rod 2 102, it is ensured that the left support leg 2 and the right support leg 3 always maintain parallel movement, thus increasing stability.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
