Description

Technical Field

[0001] This utility model belongs to the field of children's dining chair technology, and relates to a leg folding connection structure and a children's dining chair. Background Technology

[0002] Currently, high chairs are essential items for infants and toddlers, mainly designed to provide safe and comfortable conditions for them to eat.

[0003] For example, a utility model patent with application number CN202321704449.7 provides a multifunctional children's dining chair, including: a support frame with a sliding groove and at least two first locking parts; a backrest body connected to the support frame; a seat body with a first slider, a first locking component, and a second locking part, wherein the first slider is movably connected to the sliding groove; and a barrier body including a ring and a stop post, wherein the two ends of the ring are detachably connected to the two sides of the backrest body, one end of the stop post is connected to the middle of the ring, and the other end of the stop post is provided with a second locking component.

[0004] In summary, some existing technical solutions use fixed leg supports that cannot be folded and are difficult to store, leaving considerable room for improvement. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a leg folding connection structure and a children's dining chair.

[0006] The objective of this utility model can be achieved through the following technical solution: a leg folding connection structure, comprising:

[0007] The first seat body is provided with a first limiting groove;

[0008] The second seat is rotatably connected to the first seat. The second seat is provided with a second limiting groove, which includes a locked position and an unlocked position. The first limiting groove is aligned with the second limiting groove and can be offset by the relative rotation of the second seat and the first seat.

[0009] A locking member is movably connected to the second limiting groove and can move to the locked position or the unlocked position. The moving direction of the locking member is parallel to the axis of rotation of the second seat body around the first seat body. The locking member is provided with a blocking part. When the locking member moves to the locked position, the blocking part is located in the first limiting groove. When the locking member moves to the unlocked position, the blocking part is separated from the first limiting groove.

[0010] In the aforementioned leg folding connection structure, a return spring is also included. The two ends of the return spring are in contact with the second seat and the locking member, respectively. The return spring pushes the locking member to move from the unlocked position to the locked position.

[0011] In the above-mentioned leg folding connection structure, the second seat body is also provided with a positioning surface. When the locking member is in the locked position, a portion of the return spring near the locking member contacts the locking member, and the other portion of the return spring near the locking member contacts the positioning surface.

[0012] In the aforementioned leg folding connection structure, an unlock button is also included, and the second seat is also provided with a locking surface. The unlock button contacts the locking member, and the locking member is located in the locked position when the unlock button contacts the locking surface.

[0013] In the aforementioned leg folding connection structure, the second seat body is further provided with an unlocking surface, and the locking member is located in the unlocking position when it contacts the unlocking surface.

[0014] In the aforementioned leg folding connection structure, the first seat body is further provided with a travel groove, and the second seat body is further provided with a travel column. The travel column is located in the travel groove and moves within the travel groove through the relative rotation of the second seat body and the first seat body.

[0015] A children's dining chair is also provided, including the aforementioned leg folding connection structure, and further including: a first leg and a second leg, wherein the first seat is connected to the first leg, and the second seat is connected to the second leg.

[0016] In the aforementioned children's high chair, the second leg is provided with a slot, and the second seat is also provided with a plug, through which the second seat can be inserted into the slot of the second leg.

[0017] The aforementioned children's high chair also includes a locking pin and a locking spring. The second leg is also provided with a locking hole. The two ends of the locking spring are in contact with the second seat and the locking pin, respectively. When the insert is inserted into the slot to a certain position, the locking spring pushes the locking pin away from the second seat and inserts it into the locking hole.

[0018] In the aforementioned children's high chair, the locking pin is provided with an unlocking ramp. When the insert is inserted into the slot, the side wall of the locking hole pushes the locking pin closer to the second seat body through the unlocking ramp.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. When the locking member moves to the locked position, the blocking part is located in the first limiting groove. At this time, the locking member is simultaneously located in the first limiting groove and the second limiting groove, thereby restricting the relative rotation of the second seat and the first seat. When the locking member moves to the unlocked position, the blocking part separates from the first limiting groove. At this time, the locking member is located alone in the second limiting groove, thereby allowing the relative rotation of the second seat and the first seat. Therefore, by changing the locking member, the relative rotation of the second seat and the first seat is locked, and the rotation and folding of the second seat and the first seat can be realized.

[0021] 2. The reset spring pushes the locking member from the unlocked position to the locked position, so that the locking member remains in the locked state when the first limit groove and the second limit groove are aligned and are not affected by external force, ensuring that the second seat will not suddenly rotate and fold relative to the first seat, thus ensuring the safety and reliability of the structure.

[0022] 3. When the locking element is in the locked position, a portion of the return spring near the locking element contacts the locking element, and the other portion of the return spring near the locking element contacts the positioning surface. Therefore, when the return spring pushes the locking element, it pushes until the locking element and the positioning surface are on the same plane and then stops. The positioning surface plays a good positioning role.

[0023] 4. When the unlock button contacts the locking component, the locking component is in the locked position when it contacts the locking surface via the unlock button. Therefore, the locked position is exactly one of the extreme positions of the locking component's movement stroke.

[0024] 5. When the locking component contacts the unlocking surface, it is in the unlocked position. Therefore, the unlocking position is exactly one of the extreme positions of the locking component's movement stroke. At the same time, the stroke of the locking component is limited to prevent it from compressing the spring too much and causing damage to the elasticity.

[0025] 6. The stroke column is located in the stroke groove and moves within the stroke groove through the relative rotation of the second seat and the first seat. The stroke column can contact the side walls at both ends of the stroke groove, thereby limiting the maximum relative rotation range between the second seat and the first seat.

[0026] 7. The second base can be detachably connected to the second leg by inserting a plug into the slot of the second leg. Attached Figure Description

[0044] like Figures 1-7 As shown, a leg folding connection structure includes: a first seat 100, a second seat 200, and a locking member 300.

[0045] The first seat 100 is provided with a first limiting groove 110.

[0046] The second seat 200 is rotatably connected to the first seat 100. The second seat 200 is provided with a second limiting groove 210, which includes a locked position and an unlocked position. The first limiting groove 110 is aligned with the second limiting groove 210 and can be offset by the relative rotation of the second seat 200 and the first seat 100.

[0047] The locking member 300 is movably connected to the second limiting groove 210 and can be moved to the locked position or the unlocked position. The moving direction of the locking member 300 is parallel to the axis of rotation of the second seat 200 around the first seat 100. The locking member 300 is provided with a blocking part 310. When the locking member 300 moves to the locked position, the blocking part 310 is located in the first limiting groove 110. When the locking member 300 moves to the unlocked position, the blocking part 310 is separated from the first limiting groove 110.

[0048] In this embodiment, when the locking member 300 moves to the locked position, the blocking part 310 is located in the first limiting groove 110. At this time, the locking member 300 is simultaneously located in the first limiting groove 110 and the second limiting groove 210, thereby restricting the relative rotation between the second seat 200 and the first seat 100. When the locking member 300 moves to the unlocked position, the blocking part 310 separates from the first limiting groove 110. At this time, the locking member 300 is located alone in the second limiting groove 210, thereby allowing the relative rotation between the second seat 200 and the first seat 100. Therefore, by changing the locking member 300, the locking of whether the second seat 200 and the first seat 100 can rotate relative to each other is achieved, and the rotation and folding of the second seat 200 and the first seat 100 can be realized.

[0049] like Figures 1-10 As shown, based on the above embodiment, a return spring 400 is also included. The two ends of the return spring 400 are in contact with the second seat 200 and the locking member 300, respectively. The return spring 400 pushes the locking member 300 to move from the unlocked position to the locked position.

[0050] In this embodiment, the reset spring 400 pushes the locking member 300 to move from the unlocked position to the locked position, so that the locking member 300 remains in the locked state when the first limiting groove 110 is aligned with the second limiting groove 210 and is not affected by external force, ensuring that the second seat 200 will not suddenly rotate and fold relative to the first seat 100, thus ensuring the safety and reliability of the structure.

[0051] like Figures 1-10 As shown, based on the above embodiment, the second seat 200 is further provided with a positioning surface 220. When the locking member 300 is in the locked position, a portion of the return spring 400 near the end of the locking member 300 contacts the locking member 300, and another portion of the return spring 400 near the end of the locking member 300 contacts the positioning surface 220.

[0052] In this embodiment, when the locking member 300 is in the locked position, a portion of the return spring 400 near the end of the locking member 300 contacts the locking member 300, and the other portion of the return spring 400 near the end of the locking member 300 contacts the positioning surface 220. Therefore, when the return spring 400 pushes the locking member 300, it pushes until the locking member 300 and the positioning surface 220 are on the same plane and then stops. The positioning surface 220 plays a good positioning role.

[0053] like Figures 1-10 As shown, based on the above embodiment, it also includes an unlock button 500, and the second base 200 is also provided with a locking surface 230. The unlock button 500 contacts the locking member 300, and the locking member 300 is located in the locked position when the unlock button 500 contacts the locking surface 230.

[0054] In this embodiment, the unlock button 500 contacts the locking member 300. When the locking member 300 contacts the locking surface 230 through the unlock button 500, it is in the locked position. Therefore, the locked position is exactly one of the extreme positions of the movement stroke of the locking member 300.

[0055] like Figures 1-10 As shown, based on the above embodiment, the second seat 200 is further provided with an unlocking surface 240, and the locking member 300 is located in the unlocking position when it contacts the unlocking surface 240.

[0056] In this embodiment, the locking member 300 is in the unlocked position when it contacts the unlocking surface 240. Therefore, the unlocked position is exactly one of the extreme positions of the movement stroke of the locking member 300. At the same time, the stroke of the locking member 300 is limited to prevent it from compressing the spring too much and causing damage to the elasticity.

[0057] like Figures 1-10 As shown, based on the above embodiment, the first seat 100 is further provided with a travel groove 120, and the second seat 200 is further provided with a travel column 250. The travel column 250 is located in the travel groove 120 and moves within the travel groove 120 through the relative rotation of the second seat 200 and the first seat 100.

[0058] In this embodiment, the stroke column 250 is located in the stroke groove 120 and moves within the stroke groove 120 through the relative rotation of the second seat 200 and the first seat 100. The stroke column 250 can contact the side walls at both ends of the stroke groove 120, thereby limiting the maximum relative rotation range between the second seat 200 and the first seat 100.

[0059] like Figures 1-10As shown, a children's dining chair includes the aforementioned leg folding connection structure, and further includes: a first leg 600 and a second leg 700, wherein the first seat 100 is connected to the first leg 600, and the second seat 200 is connected to the second leg 700.

[0060] In this embodiment, the first seat 100 is connected to the first leg 600 and the second seat 200 is connected to the second leg 700. The relative folding of the second leg 700 and the first leg 600 is achieved by the relative rotation of the second seat 200 and the first seat 100.

[0061] like Figures 1-10 As shown, based on the above embodiment, the second leg body 700 is provided with a slot 710, and the second seat body 200 is also provided with a plug 260, through which the second seat body 200 can be inserted into the slot 710 of the second leg body 700.

[0062] In this embodiment, the second base 200 can be detachably connected to the second leg 700 by inserting the plug 260 into the slot 710 of the second leg 700.

[0063] like Figures 1-10 As shown, based on the above embodiment, it also includes a locking pin 800 and a locking spring 900. The second leg body 700 is also provided with a locking hole 720. The two ends of the locking spring 900 are in contact with the second seat body 200 and the locking pin 800, respectively. When the insert block 260 is inserted into the slot 710 to a certain position, the locking spring 900 pushes the locking pin 800 away from the second seat body 200 and inserts it into the locking hole 720.

[0064] In this embodiment, when the insert 260 is inserted into the slot 710 to a certain position, the locking spring 900 pushes the locking pin 800 away from the second seat 200 and inserts it into the locking hole 720, thereby locking the second seat 200 and the second leg 700. When unlocking is required, the locking pin 800 can be pressed close to the second seat 200 to exit the locking hole 720.

[0065] like Figures 1-10 As shown, based on the above embodiment, the locking pin 800 is provided with an unlocking ramp 810. When the insert block 260 is inserted into the slot 710, the side wall of the locking hole 720 pushes the locking pin 800 closer to the second seat 200 through the unlocking ramp 810.

[0066] In this embodiment, when the insert 260 is inserted into the slot 710, the side wall of the locking hole 720 pushes the locking pin 800 closer to the second seat 200 through the unlocking ramp 810. Therefore, when the second leg 700 is pushed into the second seat 200, the locking pin 800 can automatically retract without pressing it by hand.
