[0017] The utility model provides a switch assembly for a baby diaper stand, which comprises a first shell, a second shell, a support frame, a button block, a limit block and a positioning piece. The button is arranged in a through slot and can push the insert tube to drive the button to move through the connection with the slot through the insert tube, and can drive the entire positioning piece to move and adjust its position during the movement. The positioning piece moves into the support frame through the first connecting slot and then into the second connecting slot to limit and lock the support rod inside the support frame so that it cannot be rotated up and down. At the same time, the limit rod inside the first shell limits the position of the positioning piece at the top. The setting of the limit rod can support the positioning piece when the button block is half open, thereby ensuring the stability of the whole. It is ensured that it will not shake or shift, causing the support rod to rotate, and the overall structure is more stable.

[0018] When it is necessary to limit and lock the support rod, the button block is moved outward when the insertion tube is moved outward, and the entire positioning piece is driven to move into the support frame during the movement, and after passing through the first connecting groove and entering the second connecting groove, the support rod inside the support frame is limited and locked, so that it cannot be rotated up and down. The limiting protrusion at the end of the limiting block automatically moves upward under the action of the torsion spring and the rotating shaft, and is stuck in the buckle groove at the bottom of the button block, limiting the position of the button block from the bottom to prevent the button block from retracting inward, thereby playing the role of limiting insurance;

[0019] When the support rod needs to be unlocked and adjusted, it is necessary to first bend the limit block to make the limit protrusion at the end of the limit block move downward in a circular motion away from the buckle slot, thereby releasing the limit retraction of the button block, pushing the button block inward, driving the positioning piece and the insert tube to move inward. When pushed into place, the positioning piece exits the second connecting groove and the first connecting groove, and at the same time, the positioning piece is separated from the limit rod to release the limit on the positioning piece. After the positioning piece moves, the support rod is not blocked by the positioning piece and can be adjusted movably in the support frame to achieve unlocking. After the insert tube and the button block move inward, the limit block is automatically driven by the torsion spring and the rotating shaft to rotate the limit protrusion upward and be stuck in the limit groove, thereby defining the position of the insert tube and the button block, and maintaining the active state of the support rod;

[0020] When the support rod needs to be locked again, there is no need to bend the limit block. The support rod is lifted and directly pushed to push the insert tube to drive the button block to move outward. At the same time, the inclined surface of the limit groove rubs against the contact surface of the limit protrusion, driving the limit block to move downward in a circular motion as a whole. The limit protrusion rotates out of the limit groove, and the insert tube and the button block can continue to drive the positioning piece to move outward. The positioning piece moves into the support frame through the first connecting groove and then into the second connecting groove to limit and lock the support rod inside the support frame, so that it cannot be rotated up and down to achieve locked positioning;

[0021] The entire switch assembly can press the insertion tube to realize the limit locking of the positioning piece on the support rod in the flattened state, maintaining the stability of the overall structure and simple and convenient operation. The button block can also be limited and locked for secondary protection to avoid accidental contact with the button block that may cause the support rod to move, thereby ensuring overall stability and safety.

DETAILED DESCRIPTION

[0029] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0030] See also Figure 1-5, an embodiment of the utility model provides a switch assembly of a baby diaper stand, comprising: a body 1 provided with a support rod 11;

[0031] The switch body 2 includes a first housing 3, a second housing 4, and a support frame 5. The first housing 3 engages with the second housing 4 and has the support frame 5 disposed therein. A through slot 31 and a slot 41 are respectively provided through the first and second housings 3, 4. A fixing block 42 is fixed to the bottom of the slot 41.

[0032] The button block 6 is movably arranged inside the through slot 31. An extension tube 61 is fixedly provided inside the button block 6. An inserting tube 62 is inserted into the extension tube 61. The inserting tube 62 is inserted into the slot 41. A limiting groove 60 is provided at the bottom of the inner wall of the button block 6.

[0033] The limiting block 7 is arranged inside the fixing block 42, and a limiting protrusion 71 is provided on the top of one end of the limiting block 7 close to the button block 6;

[0034] The positioning piece 8 is fixedly disposed on the top of the extension tube 61 .

[0035] The present embodiment provides a switch assembly for a baby diaper stand, which comprises a first shell 3, a second shell 4, a support frame 5, a button block 6, a limit block 7 and a positioning piece 8. The button 6 is arranged in the through slot 31 and is connected to the slot 41 through the insert tube 62, which can push the insert tube 62 to drive the button 6 to move, and during the movement, the entire positioning piece 8 is driven to move and adjust its position. The positioning piece 8 moves into the support frame 5 through the first connecting slot 511 and then into the second connecting slot 521 to limit and lock the support rod 11 inside the support frame 5 so that it cannot be rotated up and down. At the same time, the limit rod 34 on the inside of the first shell 3 limits the position of the positioning piece 8 at the top. The setting of the limit rod 34 can support the positioning piece 8 when the button block 6 is half open, thereby ensuring the overall stability, ensuring that it will not shake or shift, causing the support rod 11 to rotate, and the overall structure is more stable.

[0036] When it is necessary to limit and lock the support rod 11, the insertion tube 62 is moved outward, and the button block 6 is moved outward at the same time. During the movement, the entire positioning piece 8 is driven to move into the support frame 5, and after passing through the first connecting groove 511 and entering the second connecting groove 521, the support rod 11 inside the support frame 5 is limited and locked, so that it cannot be adjusted up and down. The limiting protrusion 71 at the end of the limiting block 7 automatically moves upward under the action of the torsion spring 72 and the rotating shaft 44, and is stuck in the buckle groove 64 at the bottom of the button block 6, limiting the position of the button block 6 from the bottom to prevent the button block 6 from retracting inward, thereby playing the role of limiting insurance;

[0037] When the support rod 11 needs to be unlocked and adjusted, it is necessary to first bend the limit block 7 to make the limit protrusion 71 at the end of the limit block 7 move downward in a circular motion to leave the buckle slot 64, thereby releasing the limit retraction of the button block 6, pushing the button block 6 inward, driving the positioning piece 8 and the insertion tube to move inward. When pushed into place, the positioning piece 8 exits the second connecting groove 521 and the first connecting groove 511, and at the same time, the positioning piece 8 separates from the limit rod 34 to release the limit of the positioning piece 8. After the positioning piece 8 moves, the support rod 11 is not blocked by the positioning piece 8 and can be adjusted in the support frame 5 to achieve unlocking. After the insertion tube 62 and the button block 6 move inward, the limit block 7 is automatically driven by the torsion spring 72 and the rotating shaft 44 to rotate the limit protrusion 71 upward and get stuck in the limit slot 60, thereby limiting the position of the insertion tube 62 and the button block 6, and maintaining the active state of the support rod 11;

[0038] When it is necessary to lock the support rod 11 again, there is no need to bend the limit block 7. The support rod 11 is lifted and directly pushed to push the insert tube 62 to drive the button block 6 to move outward. At the same time, the inclined surface of the limit groove 60 rubs against the contact surface of the limit protrusion 71, driving the limit block 7 to move downward in a circular motion as a whole. The limit protrusion 71 rotates out of the limit groove 60. The insert tube 62 and the button block 6 can continue to drive the positioning piece 8 to move outward. The positioning piece 8 moves into the support frame 5 through the first connecting groove 511 and then into the second connecting groove 521 to limit and lock the support rod 11 inside the support frame 5, so that it cannot be rotated up and down to achieve locked positioning;

[0039] The entire switch assembly can press the insert 62 to realize the limit locking of the positioning piece 8 on the support rod 11 in the flattened state, maintaining the stability of the overall structure and simple and convenient operation. The button block 6 can also be limited and locked for secondary protection to avoid accidental contact with the button block 6 causing the support rod 11 to move, thereby ensuring overall stability and safety.

[0040] In a further embodiment of the present invention, a positioning column 32 is provided on the inner wall of the first shell 3 , a limiting cavity 33 is provided at the bottom of the positioning column 32 , and a limiting rod 34 is inserted into the limiting cavity 33 .

At the same time, locking columns are evenly arranged between the first shell 3 and the second shell. The locking columns pass through the first support plate 51 and the second support plate 52 of the support frame 5 to maintain the stability of the overall internal structure. The setting of the limit rod 34 can support the positioning piece 8 when the button block 6 is half open, thereby ensuring the overall stability and ensuring that it will not shake or shift, causing the support rod 11 to rotate, and the overall structure is more stable.

[0042] In a further embodiment of this embodiment, a positioning groove 43 is provided on the inner wall of the second shell 4, the positioning column 32 matches the positioning groove 43, a positioning frame 73 is provided on the top of the limit block 7, and a rotating shaft 44 is provided for sliding inside the fixed block 42. The rotating shaft 44 passes through the fixed block 42 and the positioning frame 73, and the rotating shaft 44 passes through the torsion spring 72 and the two ends of the torsion spring 72 are respectively connected to the bottom surface of the second shell 4 and the top surface of the limit block 7.

[0043] The limit block 7 in this embodiment rotates in a circle with 44 as the axis at the lower part of the second shell 4. During the rotation, the limit protrusion 71 can be adjusted to move in a circle to achieve the locking limit of the limit protrusion 71 and the buckle groove 64, so as to limit the button block 6 as a whole. After loosening the limit block 7, the limit block 7 drives the limit protrusion 71 to automatically reset upward under the action of the torsion spring 72, and the limit protrusion 71 is clamped in the limit groove 60 or the buckle groove 64 according to the position of the button block 6.
