Technical Field

[0001] This utility model mainly relates to the technical field of baby folding beds, specifically a telescopic folding component used at the bottom of a baby folding bed and a folding frame having the component. Background Technology

[0002] A baby folding bed is a simple bed designed using joint principles. For convenience and space saving, it can be folded and stored in various ways. This type of bed is simple, practical, and easy to store. Existing patent application number 202320130629.2 discloses a folding bed structure, including a joint connector. The joint connector has two symmetrical first sliding grooves near its upper part, with the distance between the two first sliding grooves gradually increasing from top to bottom. A second sliding groove is provided on each side of the two first sliding grooves facing away from each other. Two upper rails are provided on both sides of the joint connector, with a first guide pin at one end of each upper rail close to the other. The first guide pin is embedded and can move along the... The upper rail slides along a groove; the upper rail body is slidably connected to the joint connector, and a second guide pin is provided on the upper rail body, which is slidably embedded in the second groove; there are two lower rails, each arranged side by side below an upper rail; the ends of the lower rails that are close to each other are slidably connected to the joint connector; each mounting sleeve is connected to a support base by a vertical rod, and each support base is hinged to an unlocking base located in the middle of the lower part of the bed by a connecting rod group. Although the device discloses the joint connector for folding the railing, it uses a guide pin and a groove to cooperate, resulting in relatively poor folding stability during use. After long-term use, wear and tear can easily cause the guide pin to fall off, making it impossible to fold. Utility Model Content

The lower end of the base 2 is connected to a movable tube 21, and a resettable unlocking component is provided inside the movable tube 21. The limiting ring seat 32 is movable on the outer wall of the movable tube 21 and is connected to the folding part. The unlocking component cooperates with the limiting ring seat 32.

[0030] In this invention, the unlocking component includes a spring 22, a pull post 23, a limiting tooth 24, a movable shaft 25, and a mounting base 26. The mounting base 26 is engaged with the lower opening 27 of the movable tube 21 at a corresponding position. The mounting base 26 is provided with a movable groove 265, and the limiting tooth 24 is movably placed in the movable groove 265. The limiting tooth 24 is rotatably connected to the rotating hole 264 of the mounting base 26 via a pin 242. The top of the mounting base 26 is inserted into the connection port 234 of the pull post 23. The pull post 23 has symmetrically provided mounting holes 231. The base 2 has a vertical groove 261 and a moving groove 241. The movable tube 2 passes through the mounting hole 231, the vertical groove 261 and the moving groove 241 and is slidably connected to the vertical groove 261 and the moving groove 241. The top of the pull column 23 is connected to the spring 22. The movable tube 21 is provided with a slot 211.

[0033] An embodiment of the telescopic folding component of this utility model (Embodiment 1) is as follows:

[0034] When unlocking and folding, the pull column 23 is pulled through the pull cord or pull ring. The pull column 23 drives the movable shaft 25 to move upward in the vertical groove 261. At the same time, the movable shaft 25 moves in the moving groove 241, which drives the limiting tooth 24 to rotate along the pin 242 in the moving groove 265. This causes the limiting tooth 24 to be retracted from the slot 211 to the moving groove 265, thus quickly unlocking the limiting ring seat 32. The upward movement of the limiting ring seat 32 drives the support plate 31 to rotate, which in turn drives the linkage rod 3 to rotate downward on the base 2 and folds it. This also drives the limiting rod 4 to rotate and fold accordingly.

[0035] When in use: push the limiting ring seat 32 to move downward in the movable tube 21, drive the linkage rod 3 to rotate upward and embed it into the groove of the base 2 to be in a horizontal position. The spring 22 pushes the pull column 23, and the pull column 23 pushes the movable shaft 25 to move downward in the vertical groove 261, and at the same time move in the moving groove 241, so that the limiting tooth 24 rotates along the pin shaft 242 in the moving groove 265 and extends out from the slot 211 to fix the limiting ring seat 32.
