Description

Technical Field

[0001] This utility model relates to a bracket, and in particular to a multifunctional adjustable folding bracket, which is mainly suitable for placing baby bathtubs or children's high chairs or for drying clothes. Background Technology

[0002] In daily life, bathing infants and young children is a rather strenuous task. Baby bathtubs are used to bathe babies. The traditional way is to place the bathtub directly on the ground and have the adult squat or sit on a low stool to bathe the baby. Squatting or sitting for a long time can easily affect the health of the adult's knees and waist, especially for some elderly people. It is very difficult to stand up after squatting for a long time, and they may even feel dizzy. Therefore, people invented baby bathtub supports, such as the patent publication number CN214284663U, entitled "Upper and Lower Double-Layer Combined Baby Bathtub Support with Rotary Positioning Structure". It includes an upper support and a lower support. The upper support consists of four upper support rods, with a first connecting rod and a second connecting rod between the four upper support rods. The lower support consists of four lower support rods, each with a plug at its upper end. A third connecting rod and a fourth connecting rod are arranged between the four lower support rods. A rotary positioning device is provided at the upper end of the intersection of the third and fourth connecting rods. The rotary positioning device includes a positioning seat fixed to the third connecting rod. The bottom of the positioning seat has two positioning protrusions, one in front and one behind, which contact the side wall of the fourth connecting rod. A positioning pin is provided in the positioning seat, with a baffle on the positioning pin. A spring is provided on the outer wall of the positioning pin, and a convex arc is provided on the baffle. A top cover is provided on the upper part of the positioning seat, and a sliding plate is provided between the top cover and the positioning seat. An arc-shaped groove is opened at the bottom of the sliding plate, which matches the convex arc at the top of the positioning pin. However, the structure has the following drawbacks: First, the bracket can only be used to place a bathtub, which is a single function; second, the bracket can only hold bathtubs of the corresponding size, which is not very versatile. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a multi-functional adjustable folding bracket that can accommodate bathtubs of different sizes, has good versatility, multiple functions, and is easy to use.

[0004] The technical solution of this utility model for a multifunctional adjustable folding bracket is as follows: it includes a support foot, and two sets of left and right rotating adjustment frames are set on the upper part of the support foot. The rotating adjustment frame includes a fixed shell, which is fixed to the upper part of the support foot. Rotating parts are respectively set at the front and rear ends of the fixed shell. The rotating parts are rotated and limited by the fixed shell through a rotation limiting device. A rotating frame is set between the front and rear rotating parts, and the rotating frame is fixedly connected to the rotating parts.

[0005] Furthermore, the support feet are divided into two sets, front and rear. Each support foot includes a first support rod and a second support rod, which intersect each other and are rotatably connected at the intersection via a pivot. Support crossbars are respectively provided on the top of the first and second support rods, and the fixed shell is fixed to the support crossbars by fasteners.

[0006] Furthermore, a first reinforcing rod is provided between the first support rod of the front set of support legs and the first support rod of the rear set of support legs, and a second reinforcing rod is provided between the second support rod of the front set of support legs and the second support rod of the rear set of support legs.

[0026] This utility model relates to a multifunctional adjustable folding bracket, such as... Figure 1 — Figure 8 As shown, it includes a support leg 1, and two sets of left and right rotating adjustment frames 2 are set on the upper part of the support leg 1. The rotating adjustment frame 2 includes a fixed shell 21, which is fixed to the upper part of the support leg 1. Rotating parts 22 are respectively set at the front and rear ends of the fixed shell 21. The rotating parts 22 are rotated and limited by the fixed shell 21 through a rotation limiting device. A rotating frame 23 is set between the front and rear rotating parts 22, and the rotating frame 23 is fixedly connected to the rotating parts 22.

[0027] Furthermore, the support feet 1 consist of two sets, front and rear, each including a first support rod 11 and a second support rod 12. The first support rod 11 and the second support rod 12 intersect each other and are rotatably connected at the intersection via a pivot. Support crossbars 13 are respectively provided on the upper ends of the first support rod 11 and the second support rod 12. The fixed shell 21 is fixed to the support crossbars 13 by fasteners. The first support rod 11 and the second support rod 12 intersect each other in an "X" shape via a pivot. They can be adjusted to rotate to a vertical position, which is the folded state. They can also be adjusted to rotate to an "X" shaped intersection, which is the unfolded state. With the support crossbars 13, insertion holes can be made in the support crossbars 13. An internally threaded post is provided at the lower part of the fixed shell 21. The fixed shell 21 is inserted into the insertion hole through the internally threaded post and then fixed to the internally threaded post by fasteners such as screws or studs, so that the fixed shell 21 and the support crossbars 13 are assembled tightly and securely.

[0028] Furthermore, a first reinforcing rod 14 is provided between the first support rod 11 of the first set of support legs 1 and the first support rod of the second set of support legs 1, and a second reinforcing rod 15 is provided between the second support rod 12 of the first set of support legs 1 and the second support rod of the second set of support legs 1. With the first reinforcing rod 14 and the second reinforcing rod 15, on the one hand, when the first support rod 11 and the second support rod 12 of one set of support legs 1 are folded or unfolded by hand, the first support rod 11 can drive the first support rod 11 of the other set of support legs 1 to move synchronously through the first reinforcing rod 14, and the second support rod 12 can drive the second support rod 12 of the other set of support legs 1 to move synchronously through the second reinforcing rod 15. On the other hand, the first reinforcing rod 14 and the second reinforcing rod 15 can improve the connection reliability between the two sets of support legs 1, ensuring a more stable and reliable structure.

[0029] Furthermore, an adjusting plate 16 is provided on the side wall of the first support rod 11. The adjusting plate 16 is fixed to the first support rod 11 via a rotating shaft. Two or more adjusting grooves 17 are opened under the adjusting plate 16. A fixing shaft 18 is provided on the side wall of the second support rod 12. The adjusting plate 16 cooperates with the fixing shaft 18 via the adjusting grooves 17. When adjusting support leg 1, first rotate the adjusting groove 17 of adjusting piece 16 upwards to disengage it from fixed shaft 18. Then, the first support rod 11 and the second support rod 12 can be rotated and adjusted via the pivot. If both are rotated to vertical, they are in a folded state; if they are rotated to an "X" intersection, they are in an unfolded state. The height of the entire support is different depending on the angle of intersection. After adjustment, the adjusting piece 16 of the first support rod 11 can be rotated to make the adjusting groove 17 engage with the fixed shaft 18 of the second support rod 12, thereby positioning the first support rod 11 and the second support rod 12 (i.e., maintaining them in this state). There are 2-3 adjusting grooves 17 on adjusting piece 16, and the height of the entire support can be adjusted in 2-3 levels. Different heights of the support can meet the needs of different people. For example, when placing a baby bathtub on the support, adults bathing the baby may have different heights. By adjusting the height of the support, the height of the bathtub can correspond to the height of the adults, making it convenient for adults of different heights to bathe the baby, thus improving versatility.

[0030] Furthermore, two or more fabric strips 19 are horizontally arranged on the upper part of the support leg 1, and the two ends of the fabric strips 19 pass through the fixing shell 21 and are fixed to the support crossbar 13. When the height of the bracket is adjusted to the lowest state, the horizontally arranged fabric strips 19 can be stretched to a taut state. At this time, the bracket can be used as a stool, and people can sit on the fabric strips 19 on the upper part of the support leg 1.

[0031] Furthermore, the lower parts of the fixed shell 21 and the supporting crossbar 13 are respectively provided with through holes 41. A pull rod 42 is installed in the through hole 41 of the supporting crossbar 13. The cloth strip 19 passes through the through hole 41 of the fixed shell 21 and the supporting crossbar 13, and the head of the cloth strip 19 is fitted onto the outer wall of the pull rod 42. Sleeve holes are formed at both ends of the cloth strip 19. First, the two ends of the cloth strip 19 are passed through the through hole 41 of the fixed shell 21 and the lower part of the supporting crossbar 13. Then, the pull rod 42 is inserted into the sleeve hole of the cloth strip 19 through the through hole 41. The pull rod 42 plays a role in tightening and supporting the cloth strip 19.

[0032] Furthermore, fixing holes 43 are respectively provided on the upper part of the supporting crossbar 13 and the fixing shell 21. A specially designed children's dining chair can be placed on the bracket. The bottom of the children's dining chair is provided with protruding feet around its perimeter, and mounting holes are provided in the center of the feet. The mounting holes of the feet correspond to the fixing holes 43. The children's dining chair is fixed to the supporting crossbar 13 by fasteners passing through the mounting holes and fixing holes 43.

[0033] Furthermore, the rotation limiting device includes first grooves 24 formed at the front and rear ends of the fixed shell 21, and first toothed grooves 25 formed on the inner wall of the first grooves 24. A second groove 26 is formed on the side of the rotating member 22 near the fixed shell 21, and a second toothed groove 27 is formed on the inner wall of the second groove 26. The first grooves 24 and the second grooves 26 correspond to each other. A gear 28 is provided in the first grooves 24 and the second grooves 26.
