Technical Field
[0001] This utility model relates to the field of children's dining chair technology, and in particular to a dining chair with reinforced support legs. Background Technology
[0002] A high chair is an assistive seat designed specifically for children aged 6 months to 6 years to cultivate independent eating habits and adapt to the height of family dining tables. Its core functions include safety features, and as high chair structures continue to evolve, higher requirements are placed on their structural strength.
[0003] Existing children's high chairs are mainly made of solid wood, metal, or plastic. Compared to children's high chairs made of solid wood and metal, plastic high chairs are lighter, making them easier to move and store. Moreover, most of them are made of food-grade plastic, which is non-toxic and harmless, and meets the safety standards for children's products.
[0004] However, plastic child seats have the following disadvantages: the support legs of plastic high chairs may age after long-term use, especially at the connection between the front and rear support legs, where the structural strength decreases after long-term use, thus reducing the stability of the seat. Utility Model Content
[0005] The purpose of this invention is to provide a dining chair with reinforced support legs, which has the effects of high structural strength and strong seat stability.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dining chair with reinforced support legs, comprising a dining chair body, the dining chair body comprising: a support leg assembly, the support leg assembly comprising a plurality of front support legs and a plurality of rear support legs; a connector, the connector being integrally formed, at least one of the front support legs and the rear support legs being connected through the connector; a reinforcing plate, the reinforcing plate being fixedly connected to the connector; wherein, the connector is provided with a reinforcing plate mounting groove for positioning and engaging with the reinforcing plate during installation, a connecting and reinforcing structure is provided between the reinforcing plate and the support leg assembly, and the reinforcing plate is connected to the support leg assembly through the connecting and reinforcing structure.
[0007] By adopting the above technical solution, reinforcing plates are set inside the connectors. Plastic dining chairs tend to age after long-term use, affecting the structural strength of the chair. By reinforcing the connectors with reinforcing plates, the overall strength can be maintained even after the plastic ages. Furthermore, the support leg assembly and the connectors are reinforced with connecting reinforcements, which improves the connection strength between the support leg assembly and the connectors, further enhancing the stability of the seat, structural integrity, and durability.
[0008] A further feature of this invention is that the connection reinforcement structure includes a first connection reinforcement component connected to the front support leg. The first connection reinforcement component has a first insertion part at one end near the front support leg, and the front support leg has a corresponding first insertion groove. The first connection reinforcement component is positioned and inserted into the first insertion groove.
[0009] By adopting the above technical solution, the user can improve the connection strength between the front support leg and the connector through the first connecting reinforcement. When the user installs the front support leg, the first plug part of the first connecting reinforcement is inserted into the first plug slot, which improves the ease of installation of the front support leg.
[0010] A further feature of this invention is that the first connecting reinforcement member has a positioning protrusion and / or a positioning groove on the side near the reinforcing plate, and the reinforcing plate has a corresponding positioning groove and / or positioning protrusion, wherein the positioning protrusion and the positioning groove are positioned and engaged.
[0011] By adopting the above technical solution, when the reinforcing plate and the first connecting reinforcement are connected, the positioning protrusion is inserted into the positioning groove, which facilitates the positioning and installation of the first connecting reinforcement and improves the ease of installation of the first connecting reinforcement.
[0012] A further feature of this invention is that the connection reinforcement structure includes a second connection reinforcement component connected to the rear support leg, the second connection reinforcement component includes a second insertion part, the rear support leg is provided with a corresponding second insertion groove, and the second insertion part is positioned and inserted into the second insertion groove.

When installing the rear support leg, the second plug part of the second connecting reinforcement is inserted into the second plug slot, which facilitates positioning and improves the ease of installation of the rear support leg.
[0014] A further feature of this invention is that the second connecting reinforcement includes a rotating piece and a locking piece. The second connecting reinforcement is rotatably mounted on the connector. The locking piece has a plurality of locking protrusions, and the rotating piece has a locking hole. An elastic element is provided between the locking piece and the connector. The elastic element has a tendency to drive the locking piece against the reinforcement plate and to position the locking protrusions into the locking hole.
[0015] By adopting the above technical solution, the rear support leg can rotate relative to the connecting piece via the rotating plate to adjust the angle between the front support leg and the rear support leg, which facilitates seat adjustment. When the user adjusts the angle between the front support leg and the rear support leg, the elastic element is in a compressed state under the action of external force, and the locking protrusion of the locking plate separates from the locking hole, allowing the rotating plate to rotate. When the rear support leg is in the locked state, under the action of the elastic force of the elastic element, the locking plate abuts against the reinforcing plate, and at the same time, the locking protrusion of the locking plate inserts into the locking hole to achieve locking of the rotating plate.
[0016] A further feature of this invention is that the second connecting reinforcement has an unlocking button, the unlocking button has an unlocking protrusion, the unlocking protrusion corresponds one-to-one with the locking protrusion, the unlocking protrusion abuts against the locking protrusion, and the unlocking protrusion is positioned and engaged with the locking hole; the unlocking protrusion is used to push the locking protrusion out of the corresponding locking hole, so that the locking piece and the reinforcement plate are separated from each other.
[0017] By adopting the above technical solution, when the user presses the unlock button, the unlock protrusion moves to the side of the locking protrusion and pushes the locking protrusion away from the locking hole. When the locking protrusion is completely pushed away from the locking hole, the locking piece separates from the reinforcing plate, and the rotating piece can rotate.

[0035] The present invention will be further described below with reference to the accompanying drawings.
[0036] A type of dining chair with reinforced support legs, such as Figure 1-3 As shown, the chair includes a main body 1, which includes a support leg assembly 2. The support leg assembly 2 has several front support legs 21 and several rear support legs 22. At least one front support leg 21 and one rear support leg 22 are connected by a connector 3. The connector 3 has a reinforcing plate 4 and a reinforcing plate mounting groove 31 for positioning and fitting the reinforcing plate 4 during installation. This facilitates the positioning and installation of the reinforcing plate 4, strengthens the structure of the connector 3, and maintains overall strength even after plastic aging, reducing deformation of the connector 3 and improving the stability of the chair. A connecting reinforcement structure 5 is provided between the reinforcing plate 4 and the support leg assembly 2, and the reinforcing plate 4 is connected to the support leg assembly 2 through the connecting reinforcement structure 5. The connecting reinforcement structure 5 improves the connection strength between the connector 3 and the support leg assembly 2, preventing damage to weak points in the connection between the connector 3 and the support leg assembly 2, thereby improving the overall stability of the chair and increasing its service life.
[0037] like Figure 2 , 3 As shown, in this embodiment, the reinforcing plate 4 is made of metal and is located inside the connector 3. The connector 3 is provided with a sealing cover 32 to seal the reinforcing plate mounting groove 31, preventing the reinforcing plate 4 from being exposed. The sealing cover 32 is provided with a buckle 321, and the reinforcing plate 4 is correspondingly provided with a groove 41, such as... Figure 3As shown, three sets of buckles 321 and slots 41 are provided at both ends of the reinforcing plate 4 near the front support leg 21 and the rear support leg 22 and at the middle position of the reinforcing plate. When the user closes the sealing cover 32, the buckles 321 are snapped into the slots 41. By setting multiple sets of slots 41 and buckles 321 to engage, the installation stability and installation accuracy of the sealing cover 32 are improved. The sealing cover 32 is not easy to shift after installation, thus preventing the sealing cover 32 from deforming.
[0038] like Figure 2 , 3 As shown, in this embodiment, the front support leg 21 and the connector 3 are connected and reinforced by a first connecting reinforcement member 51, which improves the connection strength between the front support leg 21 and the connector 3. A first insertion slot 211 is provided at one end of the first connecting reinforcement member 51 near the front support leg 21. When the user installs the front support leg 21, the first insertion part 511 of the first connecting reinforcement member 51 is inserted into the first insertion slot 211, facilitating the positioning and installation of the front support leg 21 and improving the ease of installation. Furthermore, in this embodiment, the first connecting reinforcement member 51 is located near the reinforcing plate... A positioning protrusion 512 is provided on one side of the component 4, and a positioning groove 513 is provided at the corresponding position of the reinforcing plate 4. When the first connecting reinforcement 51 is installed, the positioning protrusion 512 is inserted into the positioning groove 513, which facilitates the positioning of the first connecting reinforcement 51 during installation, improves the ease of installation of the first connecting reinforcement 51, and makes it easier for users to install. In other embodiments, the positioning protrusion 512 and the positioning groove 513 can also be provided on the reinforcing plate 4 at the same time, and the positioning groove 513 and the positioning protrusion 512 can be provided on the first connecting reinforcement 51 to further improve the positioning accuracy.
[0039] like Figure 3 , 4As shown, in this embodiment, the connecting reinforcement structure 5 further includes a second connecting reinforcement member 52 connected to the rear support leg 22. The user improves the connection strength between the rear support leg 22 and the connector 3 through the second connecting reinforcement member 52.

The second insertion part 521 and the second insertion groove 221 are positioned and inserted into each other, which facilitates the positioning and installation of the rear support leg 22 and improves the ease of installation of the rear support leg 22. In addition, the second connecting reinforcement member 52 includes a rotating piece 522 and a locking piece 523. When the rear support leg 22 rotates, the rotating piece 522 rotates relative to the connector 3 to adjust the angle between the front support leg 21 and the rear support leg 22, which facilitates the adjustment of the seat. The locking piece 523 is provided with a plurality of locking protrusions 524, and the rotating piece 522 is provided with locking holes 525. The locking piece 523 and the connector 3 are connected. An elastic element 6 is provided between the two parts. The elastic element 6 has a tendency to drive the locking piece 523 to abut against the reinforcing plate 4 and to position the locking protrusion 524 into the locking hole 525. When the rear support leg 22 is in the locked state, under the elastic force of the elastic element 6, the locking piece 523 abuts against the reinforcing plate 4, and at the same time, the locking protrusion 524 of the locking piece 523 is inserted into the locking hole 525 to lock the rotating piece 522. In addition, the second connecting reinforcement 52 is provided with a limiting protrusion 526, and the reinforcing plate 4 is provided with a limiting groove 42 along the rotation direction of the limiting protrusion 526. The second connecting reinforcement 52 is limited and anti-rotationally engaged by the limiting protrusion 526 and the limiting groove 42. During the rotation of the rear support leg 22, the limiting protrusion 526 rotates clockwise or counterclockwise along the arc-shaped limiting groove 42. The limiting protrusion 526 prevents the user from rotating the support leg 22 at too large an angle, thus avoiding structural damage.
[0040] like Figure 4 , 5 As shown, in this embodiment, the second connecting reinforcement 52 is also provided with an unlock button 7. The unlock button 7 has an unlock protrusion 71, which corresponds one-to-one with the locking protrusion 524. The unlock protrusion 71 abuts against the locking protrusion 524. When the user presses the unlock button 7, the unlock protrusion 71 is displaced to one side of the locking protrusion 524, and the locking protrusion 524 is pushed away from the locking hole 525. When the locking protrusion 524 is completely pushed away from the locking hole 525, the locking piece 523 separates from the reinforcing plate 4, and the rotating piece 522... The device is rotatable. After the user releases the unlock button 7, the locking piece 523 resets under the elastic force of the elastic element 6, and pushes the unlock button 7 to reset, making it easy for the user to control the rotation and locking of the rotating piece 522 and improving the user's ease of operation. In addition, the second connecting reinforcement 52 also includes a button mounting groove 8 for installing the unlock button 7. The inner wall of the button mounting groove 8 is provided with an anti-detachment part 81, and the unlock button 7 is provided with an anti-detachment buckle 72. The anti-detachment part 81 and the anti-detachment buckle 72 cooperate to prevent detachment and improve the installation stability of the unlock button 7.
[0041] The basic working principle of this utility model is as follows: The connecting part 3 of the main body 1 of the dining chair is connected to the front support leg 21 and the rear support leg 22. The conventional connecting part 3 of the dining chair is made of plastic. After long-term use, the plastic ages and affects the safety of the chair. By setting a reinforcing plate 4 on the connecting part 3, the overall strength of the connecting part 3 is improved, and the supporting strength can still be maintained after the external plastic ages, thereby improving the stability and safety of the chair. Since the connection between the connecting part 3 and the support leg assembly 2 is easily damaged, a first connecting reinforcement 51 is set between the front support leg 21 and the fixing plate to improve the connection strength between the front support leg 21 and the connecting part 3. A second connecting reinforcement 52 is set between the rear support leg 22 and the connecting part 3 to improve the connection strength between the rear support leg 22 and the connecting part 3. This prevents the connection between the support leg assembly 2 and the connecting part 3 from being damaged during the use of the dining chair, thereby improving the overall structural stability and durability of the dining chair.
[0042] The above description is only a preferred embodiment of the present utility model.
