Description

Technical Field

[0001] This utility model relates to a high-leg support for an integrated washing and care table, specifically a locking device for the support frame of an integrated washing and care table. Background Technology

[0002] To meet the various washing and care needs of infants and young children, a washing and care integrated nursing table has appeared on the market. It mainly includes a high stand and a bathtub set on the high stand. The high stand consists of two main support frames arranged on the left and right and connecting parts arranged in the front and back.

[0003] To achieve the connection between the main support frame and the connector, each end of the connector is provided with a connecting part, and a through connecting hole is provided on the connecting part. During assembly, the support vertical tube of the main support frame is directly inserted into the corresponding connecting hole to achieve the connection. This kind of direct insertion connection structure requires a certain assembly gap to be reserved before the insertion operation can be carried out. This will inevitably lead to the inability to achieve a complete tight fit between the connecting hole and the support vertical tube. Once the assembly is completed, it is easy to loosen, which will affect the overall support strength of the high leg bracket and cause the tilting problem to occur easily during use. This will seriously affect the safety of the nursing table. Utility Model Content

Detailed Implementation

[0013] like Figure 1-5As shown, a locking device for a high-leg support of a washing and care integrated nursing table includes a high-leg support. The high-leg support consists of two main support frames 1 arranged on the left and right and a connector 2 arranged in the front and back. Each side of the connector 2 is provided with at least one connecting part 21 connected to the support vertical tube 11 of the main support frame 1. In this figure, the connector 2 is provided with two connecting parts 21 on each side. In practice, one, three or more connecting parts 21 can be provided on each side of the connector 2 as needed.

[0014] Each of the connecting parts 21 is provided with adjacent connecting holes 211 and pin holes 212. The connecting hole 211 is used to insert into the support vertical tube 11. A locking notch 213 is opened on one side of the connecting hole 21. The locking notch 213 extends a certain distance inward toward the connecting part 21 and then extends forward to the outside of the connecting part 21, so that the connecting hole 211 forms an adjusting hole structure with an adjusting notch. In use, when the locking notch 213 is closed, it will simultaneously drive the diameter of the connecting hole 211 to reduce to achieve a locking connection. Conversely, when the locking notch 213 is open, it will drive the diameter of the connecting hole 211 to increase to facilitate its assembly and insertion with the support vertical tube 11.

[0015] The pin hole 212 is set close to the connecting hole 211. A locking block 214 is inserted into the pin hole 212. The pin hole 212 has a notch 2121 in the middle of one side of the corresponding locking notch 213 and communicates with the locking notch 213. At least one bolt hole 215 is provided on the outer wall of the connecting part 21. A locking bolt 216 is provided in the bolt hole 215. The inner end of the locking bolt 216 passes through the locking notch 213 and the notch 2121 of the pin hole in sequence and connects with the locking block 214. In use, once the locking bolt 216 is tightened, the locking bolt 216 will press against the outer wall of the connecting part 21 and close the locking notch 213, thereby reducing the size of the connecting hole 211 and tightly holding the support vertical tube 11 of the high leg bracket.

[0016] In this diagram, the bolt holes 215 mentioned above are set as two and arranged vertically. In practice, they can be set to only one, or three or even more, as needed.

[0017] To meet connection requirements, the locking block 214 is provided with a corresponding mounting groove 2141, and a locking nut 2142 is provided in the mounting groove 2141. The locking nut 2142 is connected to the front end of the locking bolt 216. Here, in order to achieve circumferential rotation constraint of the locking nut 2142, the shapes of the mounting groove 2141 and the locking nut 2142 are generally set to be compatible hexagons. In practice, other shapes can also be used as needed, as long as it can ensure that the locking nut 2142 does not rotate in the mounting groove 2141.

[0018] During assembly, first insert the support vertical tube 11 into the corresponding connecting hole 211, then install the locking nut 2142 into the mounting groove 2141 of the locking block 214, and insert the entire locking block 214 into the pin hole 212. Finally, tighten the locking bolt 216 in the bolt hole 215 relative to the locking nut 2142 on the locking block 214, so that the locking notch 213 gradually closes, causing the connecting hole 211 to shrink and hold the support vertical tube 11 tightly, thus achieving a tight fit between the two.

[0019] In summary, the high-leg support of the multifunctional washing and care unit designed in this utility model has a connecting hole 211 with a locking notch 213 on the connecting part 21 of the connector 2. Combined with the pin hole 212 with a notch groove 2121, the locking block 214 and the locking bolt 216, the connector 2 and the main support frame 1 can be effectively locked together, preventing loosening during use. This effectively improves the overall support strength of the high-leg support and enhances the safety of the care unit.

[0020] To facilitate the quick installation and positioning of the locking block 214 in the pin hole 212, an assembly limiting structure is provided between the locking block 214 and the pin hole 212. This assembly limiting structure includes a positioning protrusion 31 and a positioning groove 32, one of which is optionally located on the wall of the locking block 214 or the pin hole 212. In this figure, the positioning protrusion 31 is located on the wall of the pin hole 212, while the positioning groove 32 is located on the locking block 214. In practice, their positions can be interchanged, achieving the same technical effect.

[0021] Furthermore, to facilitate the quick assembly and positioning of the connecting part 21 on the supporting vertical tube 11, the supporting vertical tube 11 of the main support frame 1 is provided with a corresponding positioning elastic protrusion 111. During assembly, once the supporting vertical tube 11 and the connecting part 21 of the connector 2 are aligned, the positioning elastic protrusion 111 will align with the positioning hole 217 on the connecting part 21 and pop out, thereby achieving the engagement of the two and completing the quick positioning connection.

[0022] Considering the support strength of the high-leg bracket and the production cost, the main support frame 1 is generally made of metal, while the connector 2 is made of plastic.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
