[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figures 1-2 and Figure 8 This utility model provides an embodiment of a novel parent-child interactive baby crib with a long-side lifting mechanism, including a fixed joint 1. A fixed joint cover 2 is fitted onto the outer wall of the fixed joint 1. The fixed joint cover 2 can cover the surface of the fixed joint 1 for aesthetic purposes. A fixed support tube 3 is inserted into the inner wall of the bottom end of the fixed joint 1. A slot is provided at the bottom end of the fixed joint 1 to fit the top end of the fixed support tube 3, so that the fixed joint 1 can be inserted into the upper end of the fixed support tube 3. A sliding joint 4 is detachably installed on the inner side wall of the fixed support tube 3 through a lifting assembly 7. A sliding joint cover 5 is fitted onto the surface of the sliding joint 4. A bedside tube 6 is inserted into the right inner wall of the sliding joint 4. Bedside tubes 6 are provided on both sides of the fixed joint 1 and the sliding joint 4, thereby constructing the basic shape of the baby crib.
[0037] Reference Figures 5-7 The lifting assembly 7 includes a locking slider 71, which passes through and is slidably connected to the inner wall of the top end of the sliding joint 4. The inner wall of the top end of the sliding joint 4 has a transverse groove that fits the locking slider 71, allowing the locking slider 71 to move laterally only within the inner wall of the transverse groove at the top end of the sliding joint 4. The locking slider 71 is elastically connected to the inner wall of the top end of the sliding joint 4 by a spring a72. One end of the spring a72 is fixedly connected to the inner side wall of the top end of the sliding joint 4, and the other end is fixedly connected to the inner side wall of the locking slider 71. The function of the spring a72 is to disengage the locking slider 71 by moving it backward. The position after the positioning groove 9 is automatically reset. A protruding rod 74 is fixedly connected to the inner wall of the bottom left side of the sliding joint 4. The bottom end of the protruding rod 74 is elastically connected to the operation key 76 through the spring b75. The operation key 76 passes through and is slidably connected to the inner wall of the bottom end of the sliding joint 4. An annular groove is opened on the surface of the operation key 76. The protruding rod 74 passes through and is slidably connected to the inner wall of the annular groove of the operation key 76. The protruding rod 74 can support the spring b75 and automatically reset the position after the operation key 76 is moved. The bottom end of the operation key 76 is provided with a protrusion to facilitate pushing it upward.
[0038] Reference Figure 4 and Figures 6-7One end of spring b75 contacts the bottom end of protruding rod 74, and the other end of spring b75 is fixedly connected to the bottom end of the inner wall of operation key 76. The function of spring b75 is to automatically reset the position after operation key 76 is pushed upward. A contact block 77 is fixedly connected to the top end of the outer wall of operation key 76. An inclined groove is opened on the outer side wall of locking slider 71. The outer wall of contact block 77 contacts the inner wall of the inclined groove of locking slider 71. Pushing operation key 76 upward will cause contact block 77 to move on the inner wall of the inclined groove at the rear end of locking slider 71. This allows the locking slider 71 to be squeezed, causing the locking block 73 to move backward on the inner wall of the sliding joint 4, thereby disengaging from the positioning groove 9 to facilitate the raising and lowering of one side of the bed. The locking slider 71 is fixedly connected to the locking block 73 at the end away from the spring a72. The side wall of the T-shaped groove of the fixed support tube 3 is provided with a positioning groove 9. The outer wall of the locking block 73 is inserted into the inner wall of the positioning groove 9. The insertion between the two can fix the entire sliding joint 4 in multiple positions after it has moved up and down on the inner wall of the fixed support tube 3, thereby quickly adjusting the height of the bed.
[0039] Reference Figures 3-4 The inner sidewall of the fixed support tube 3 is provided with a T-shaped groove, and the outer sidewall of the sliding joint 4 is fixedly connected with two sets of guide blocks 8. The outer wall of the guide block 8 is in contact with the inner wall of the T-shaped groove of the fixed support tube 3. By providing guide blocks 8 on the outer side of the sliding joint 4 and cooperating with the T-shaped groove of the fixed support tube 3, the up and down movement of the sliding joint 4 as a whole is guided.
[0040] Working principle: In terms of overall structure, the fixed joint 1 and the fixed support tube 3 form the stable foundation of the crib. The inner wall of the bottom of the fixed joint 1 has a slot that fits into the top of the fixed support tube 3. The two are tightly connected by insertion to ensure the stability of the crib frame. The fixed joint cover 2 is fitted onto the outer wall of the fixed joint 1, which serves both an aesthetic decoration function and protects the internal structure. The sliding joint 4 is connected to the inner side of the fixed support tube 3 through the lifting component 7. The two sets of guide blocks 8 on the outer side of the sliding joint 4 cooperate with the T-shaped groove on the inner side of the fixed support tube 3 to provide precise guidance for the up and down movement of the sliding joint 4. The bedside tubes 6 are inserted into the fixed joint 1 and the sliding joint 4 on both sides respectively, together forming the basic wheels of the crib.
[0041] Under normal conditions, the locking slider 71, under the elastic force of spring a72, firmly inserts the locking block 73 into the positioning groove 9 on the side wall of the T-shaped groove of the fixed support tube 3, fixing the sliding joint 4 in its current position and preventing accidental raising or lowering of the bedside, ensuring the safety of the infant. When it is necessary to adjust the height of the bedside, the operator moves the operation key 76 upward. The protrusion design at the bottom of the operation key 76 facilitates the application of force. When the operation key 76 moves upward, the contact block 77 at its top contacts the inner wall of the inclined groove on the outside of the locking slider 71. As the operation key 76 continues to move upward, the contact block 77 slides in the inclined groove, squeezing the locking slider 71 to overcome the elastic force of spring a72, causing the locking block 73 to move backward on the inner wall of the sliding joint 4 until the locking block 73 is completely disengaged from the positioning groove 9. At this time, the sliding joint 4 is released from its locking restriction, and the operator can adjust the height according to actual needs. Manually move the sliding joint 4 up or down along the T-slot of the fixed support tube 3 to adjust the long side of the crib to a suitable height. After the height adjustment is complete, release the operation key 76. The spring b75 will activate, pushing the operation key 76 downward to reset. The contact block 77 will disengage from the inclined groove of the locking slider 71. At the same time, the elastic force of the spring a72 will push the locking slider 71 forward, causing the locking block 73 to re-insert into the corresponding positioning groove 9 on the side wall of the T-slot of the fixed support tube 3, thus firmly locking the sliding joint 4 in the new position. This completes the adjustment and fixation of the crib height. In addition, the annular groove on the surface of the operation key 76 cooperates with the protrusion 74. During the movement of the operation key 76, the protrusion 74 slides along the annular groove, which not only provides support for the spring b75 but also ensures that the operation key 76 can accurately reset after being turned, improving the stability and reliability of the operation.
[0042] The T-shaped groove on the inner side of the fixed support tube 3 and the guide block 8 on the outer side of the sliding joint 4 cooperate to form a stable guiding structure. The guide block 8 slides along the T-shaped groove, restricting the movement direction of the sliding joint 4 and preventing it from deviating or shaking during the lifting process. This ensures that the lifting process of the crib is smooth and stable, further enhancing the safety of the crib during use.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
