At the upper end of the fixed tube 103, the inner fixed sleeve 1042 is connected to the upper end of the inner fixed tube 102, the inner fixed sleeve 1042 is inserted into the outer fixed sleeve 1041, and is clamped with the outer fixed sleeve 1041, so that the upper part of the fixed tube is connected in one piece; the lifting tube 101 is inserted into the inner fixed tube 102, and a locking mechanism is provided in the inner fixed tube 102 to fix the support leg 100 in the fixed tube, and adjustment components 800 are installed on the long frame and the short frame of the top frame to unlock the locking mechanism.

[0035] See also Figure 3-4 The locking mechanism includes a slider 105, a locking block 106 and a plurality of corresponding locking holes opened on the inner fixed tube 102 and the outer fixed tube 103. The number of locking holes is not limited and can be formulated according to actual needs. There is a certain gap between the tube walls of the inner fixed tube 102 and the outer fixed tube 103, and the locking holes of the inner fixed tube 102 and the outer fixed tube 103 correspond to each other. A slider 105 is installed at the lower end of the lifting tube 101, and a locking block 106 is installed at the lower end of the slider 105. A locking column inserted in the locking hole is provided on the locking block 106, and the outer end of the locking column is flush with the outer tube wall of the inner fixed tube 102; when the locking column is inserted in the locking holes at different heights, the height of the lifting tube 101 in the fixed tube is different, and the height of the bed frame is different.

[0036] There are four groups of adjustment components 800, and each group of adjustment components 800 is installed at the center of the long frame and the short frame respectively; the adjustment component 800 is composed of a group of pull-wire mechanisms and two groups of unlocking mechanisms, the pull-wire mechanisms are installed at the center of the square frame, and the unlocking mechanisms are symmetrically connected to the two ends of the pull-wire mechanisms; wherein, the pull-wire mechanism is composed of an outer U-shaped connector 801, an inner U-shaped connector 802, a spring two 803 and a T-shaped connector 804, and the unlocking mechanism is composed of a pull rope 805, a connecting sleeve 806 and a spring one 807.

[0037] Among them, see Figure 5-6The outer U-shaped connector 801 in the wire pulling mechanism is installed at the center of the frame. Each set of long frames and short frames is composed of two upper support rods 300. One end of the two upper support rods 300 is connected to the three-way connector 400 respectively, and the other end is connected through the adjustment component 800.

The spring two 803 is placed in the spring accommodating groove, the lower end of the second spring 803 is connected to the bottom of the spring accommodating groove, and the top of the second spring 803 is fixedly connected to the limit block at the inner center of the outer U-shaped connecting piece 801. Therefore, when the inner U-shaped connecting piece 802 is pushed upward, the inner U-shaped connecting piece 802 moves upward along the sliding groove at the bottom of the outer U-shaped connecting piece 801, and the second spring 803 will be compressed and produce elastic deformation; when the inner U-shaped connecting piece 802 is released, under the elastic force of the second spring 803, the inner U-shaped connecting piece 802 will reset downward to its initial state.

[0038] Two groups of symmetrically arranged inclined grooves are provided on the inner U-shaped connector 802, and two groups of symmetrically arranged horizontal grooves are provided on the outer U-shaped connector 801. The two groups of horizontal grooves correspond to the two groups of inclined grooves one by one, and the angles between the horizontal grooves and the inclined grooves are obtuse; the T-shaped connector 804 is simultaneously arranged in the corresponding horizontal grooves and inclined grooves, and its two symmetrical ends respectively pass through the inclined grooves and horizontal grooves on the two side plates of the inner U-shaped connector 802, and the other end is fixedly connected to the pull rope 805 in the unlocking mechanism; when the inner U-shaped connector 802 is pulled upward, the inner U-shaped connector 802 moves upward along the groove at the bottom of the outer U-shaped connector 801, and the inclined groove moves upward accordingly, which will drive the T-shaped connector 804 to move in the horizontal groove of the outer U-shaped connector 801 in the direction away from the pull rope 805.

[0039] See also Figure 7-8The end of the pull rope 805 in the unlocking mechanism away from the pull wire mechanism is connected to the upper end of the slider 105; a pull rope guide rail 900 is provided under each lower support rod 200, and the two ends of the pull rope guide rail 900 are also fixedly connected to the three-way connector 400 and the adjustment component 800 respectively; a line hole is opened at the upper end of the lifting tube 101, and the pull rope 805 is horizontally arranged in the pull rope guide rail 900 after being led out from the T-shaped connector 804, and penetrates into the lifting tube 101 through the line hole at the upper end of the lifting tube 101, and is fixedly connected to the upper end of the slider 105; the connecting sleeve 806 is fixedly installed at the lower end of the lifting tube 101, and the slider 105 is slidably installed in the connecting sleeve 806 up and down ; A triangular slide is provided on the side wall of the lower end of the slider 105, and a triangular slider matching the triangular slide is provided at the end of the locking block 106 away from the lock column, and the locking block 106 is slidably set in the triangular slide of the slider 105 through the triangular slider, and the end of the locking block 106 close to the lock column is slidably penetrated into the connecting sleeve 806, and a spring 807 is connected between the end away from the lock column and the inner wall of the connecting sleeve 806; therefore, when the slider 105 moves upward, it will drive the locking block 106 to move in the direction away from the lock column, so that the lock column is separated from the lock holes in the inner fixed tube 102 and the outer fixed tube 103, and at the same time, the spring 807 is compressed to produce elastic deformation to achieve unlocking.

[0040] Each set of pull-wire mechanisms is connected to two sets of unlocking mechanisms, so there should be two sets of unlocking mechanisms in each fixed tube. It should be noted that the two sets of unlocking mechanisms in each fixed tube share a set of connecting sleeves 806, springs 807 and unlocking mechanisms connected to the pull rope 805 to make the overall structure simpler.

[0041] The working principle of this utility model:

[0042] When adjusting the height of the baby bed, it is only necessary to adjust the overall height of the legs 100 in the bed frame; the user holds any two opposite inner U-shaped connectors 802 with both hands and pulls them upward, at which time the inner U-shaped connector 802 moves upward along the slide groove at the bottom of the outer U-shaped connector 801, and the spring 2 803 is compressed to produce elastic deformation, and the inner U-shaped connector 802 moves upward along the slide groove at the bottom of the outer U-shaped connector 801, and the inclined slide groove moves upward accordingly, which will drive the T-shaped connector 804 to move in the horizontal slide groove of the outer U-shaped connector 801 in the direction away from the pull rope 805, thereby pulling the pull rope 805, so that the pull rope 805 in the lifting tube 101 moves upward, thereby driving the slider 105 to move upward, and then driving the locking block 106 to move in the direction away from the lock column, so that the lock column is separated from the inner fixing tube 102 and the outer fixing tube 103. The locking hole is locked, and the spring 807 is compressed to produce elastic deformation to achieve unlocking; at this time, the top frame is moved upward or downward to drive the lifting tube 101 to move upward or downward, and the inner U-shaped connecting piece 802 is loosened at the same time. The locking column will abut the inner wall of the inner fixed tube 102 during the movement. When the locking column moves to the next locking hole, the spring 807 drives the locking column in the locking block 106 to bounce into the locking hole under the elastic reset action. At the same time, under the elastic force of the spring 2 803, the inner U-shaped connecting piece 802 will reset and move downward to the initial state. At this time, the height of the lifting tube 101 in the fixed tube can be adjusted. Repeat this process as needed to adjust the height of the support leg 100 to the required height. The overall process only requires holding the inner U-shaped connecting piece 802 upward and then releasing it, and then moving the top frame upward or downward. The operation is simple, time-saving and labor-saving, convenient and fast, and the adjustment efficiency is high.
