Detailed Implementation
[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0023] Example 1: As Figures 1-3 The system includes a support frame, with two sets of support frames arranged symmetrically on the left and right sides. The support frame includes a riser 100, with an adjustable arc-shaped handle 160 inserted into the inner wall of the riser 100. A first lug 110 is fixedly connected to the outer wall of the rear end of the riser 100. The inner wall of the first lug 110 is rotatably connected to a rear support leg 130 via a pivot pin. The bottom end of the rear support leg 130 is rotatably connected to a rear roller 131 via a bearing. The outer wall of the rear support leg 130 is rotatably connected to a foot brake 132 for braking the rear roller 131. A rotating block 120 is fixedly connected to the outer wall of the bottom end of the riser 100 via bolts. A second lug 190 is fixedly installed on the side wall of the riser 100. A lifting block 210 is rotatably connected to the inner wall of the second lug 190 via a pivot pin. The rotating block 120 and the lifting block 210 are rotatably connected to a cross arm 200 via a pivot pin. A crossbar 240 is welded to the ends of both cross arms 200.
[0024] The specific application scenario of this embodiment is as follows: By setting a support frame structure that can be folded left and right, the elderly stroller can be folded for convenient multi-functional use. By setting an arc-shaped handle 160, it is easy for the operator to hold the stroller, making it easier to push the stroller with less effort. By setting a rotatable rear support leg 130, it is easy to bring the rear support leg 130 close to the arc-shaped support leg 140 when the stroller is folded, which further reduces the footprint after folding. By setting a foot brake 132, it is easy to lock the stroller when it stops moving. By setting a lifting block 210, it provides support to the bottom of the cross arm 200, thereby improving the stability of the equipment and facilitating the installation of the connecting rod 230.
[0025] Example 2: As Figure 4The bottom end of the rotating block 120 is connected to the arc-shaped support leg 140. The bottom end of the arc-shaped support leg 140 is rotatably connected to the front fork arm 141 through a bearing. The inner wall of the front fork arm 141 is rotatably connected to the front roller 142. The inner walls of the arc-shaped support leg 140 and the rear support leg 130 are rotatably connected to the tie rod 170 through a shaft pin. There are two tie rods 170, and the two tie rods 170 are rotatably connected to each other through a joint. The inner wall of the cross arm 200 near the crossbar 240 has a U-shaped groove (not marked in the figure) that runs vertically through it. The center of the inner wall of the joint is rotatably connected to the inner wall of the U-shaped groove. The seat cloth is connected between the two crossbars 240. The outer wall of the end of the crossbar 240 is fixedly installed with a buckle 250 for locking the seat cloth.
[0026] The specific application scenario of this embodiment is as follows: By setting two pull rods 170 to connect the arc-shaped support leg 140 and the rear support leg 130, the rear support leg 130 is rotatably connected to the riser 100, thereby facilitating the folding of the rear support leg 130, making the elderly stroller portable, convenient to carry and saving necessary storage space. By setting a U-shaped groove, the top of the connecting rod 230 can rotate inside the support block 210 to avoid movement interference. By setting a latch 250, it is easy for the operator to install and remove the seat cloth, improving the practicality of the equipment and facilitating multi-functional use.
[0027] Example 3: As Figure 2 and Figure 3 A sleeve 150 is fitted onto the outer wall of the top of the riser 100. A screw 151 is threaded onto the inner wall of the sleeve 150. The screw 151 is used to press and position the outer wall of the arc-shaped handle 160. An anti-slip sleeve 161 is fitted onto the handle of the arc-shaped handle 160. A brake handle 180 is fixedly installed on the outer wall of the arc-shaped handle 160. A brake 133 for manually controlling the braking of the rear roller 131 is fixedly installed at the bottom of the rear outrigger 130 near the rear roller 131. A steel wire rope is connected between the brake handle 180 and the brake 133. The steel wire rope is used to control the brake 133 to lock and brake the outer wall of the rear roller 131.
[0028] The specific usage scenario of this embodiment is as follows: by loosening the screw 151, and then by pressing or pulling the arc handle 160, the arc handle 160 is adjusted to a suitable height. Then, the screw 151 is tightened to lock the riser 100 and the arc handle 160. By holding the brake handle 180 and pulling the wire rope, the brake 133 is driven by the wire rope to brake the rear roller 131. The brake 133 is prior art. The brake 133 includes general standard parts or components known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0029] The working principle of this utility model is as follows: When the operator needs to unfold the vehicle, he holds two cross arms 200, which expand outwards. Under the pushing action of the two cross arms 200, the two left and right uprights 100 are expanded outwards. At the same time, during the unfolding process, the lifting block 210 flips outwards to push the connecting rod 230, which pushes the joint between the two pull rods 170 downwards, so that the two pull rods 170 in the folded state return to a straight shape, unfolding the rear support leg 130 and the arc-shaped support leg 140. Then, the elderly person holds the two anti-slip sleeves 161 and uses the elderly person's vehicle as a cane to practice walking on flat ground. When it is necessary to stop, the operator can press the brake handle 180 with his fingers to pull the steel cable (not marked in the figure), control the brake 133 to brake the rear roller 131, and then step on the foot brake 132 to lock the outer wall of the rear roller 131, thereby stopping the vehicle.
[0030] When the elderly need to sit up, a seat cloth (not shown in the figure) is installed on the outer wall of the two crossbars 240, and then the seat cloth is clamped and locked to the outer wall of the crossbars 240 by the buckle 250. The elderly sit on the seat cloth, and the accompanying caregiver can push the elderly cart by holding the anti-slip sleeve 161, thus providing the elderly with a means of transportation and facilitating multi-functional use.
[0031] When the elderly stroller needs to be folded, by holding the two horizontal bars 240 and pulling them upwards, the two cross arms 200 can be folded, which will cause the left and right upright tubes 100 to fold towards the middle. At the same time, the top of the connecting rod 230 slides inside the U-shaped groove. By pulling the two connecting rods 230 from the joint, the folding operation of the elderly stroller is completed.
[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
