The lock seat 41 is disposed at the upper end of the rear leg 30. The lock seat 41 has a first arc surface 411, a first slot 412, and a second slot 413. The first arc surface 411 is arranged around the rotation axis of the rear leg 30, and the first slot 412 and the second slot 413 are circumferentially spaced on the first arc surface 411.

[0038] One end of the connecting arm 20 is connected to the rear side of the front leg 10, and the other end is connected to the upper end of the rear leg 30. The direction facing the front leg 10 is the front side, and the direction facing the rear leg 30 is the rear side. The connecting arm 20 is fixedly connected to the front leg 10 and rotatably connected to the rear leg 30. The rear leg 30 can rotate around the connecting arm 20. When the rear leg 30 is rotated downwards towards the front side, the portable and foldable high chair 100 can be folded up. When the rear leg 30 is rotated upwards towards the rear side, the portable and foldable high chair 100 can be unfolded.

[0039] The lock cylinder 42 and operating member 43 of the locking assembly 40 are housed within the connecting arm 20. The lock seat 41 is located at the upper end of the rear bracket 30. An opening is provided on the side of the connecting arm 20, and the operating member 43 is housed within this opening. Part of the operating member 43 extends out of the opening. One end of the operating member 43 is connected to the connecting arm 20, and the other end is connected to the front end of the lock cylinder 42. The rear end of the lock cylinder 42 can mate with the lock seat 41. Figure 1 and Figure 2 As shown, in the portable, foldable high chair 100 usage state, even when the portable, foldable high chair 100 is unfolded, the lock cylinder 42 engages with the lock seat 41, and the rear leg 30 is locked by the locking assembly 40, thus fixing it relative to the front leg 10. For example... Figures 3-6 As shown, during the folding process of the rear tripod 30 until it is fully folded, simply press the operating component 43. The operating component 43 controls the lock cylinder 42 to separate from the lock seat 41, and the locking component 40 releases the lock on the rear tripod 30.

The lock core 42 is formed with a first clamping block 422 and a second clamping block 423 at the upper and lower ends of the second circular arc surface 421 in the circular arc direction, respectively. The second clamping block 423 includes an inner edge surface and an outer edge surface. The inner edge surface is connected with the second circular arc surface 421, and the outer edge surface is protruded from the lower side of the lock core 42. The included angle between the inner edge surface and the outer edge surface is less than 60 degrees.

[0041] The connecting arm 20 is further provided with an elastic member for driving the lock core 42 to have a tendency to protrude outward. When the lock core 42 protrudes outward to the locking position, the second circular arc surface 421 abuts against the first circular arc surface 411, and the first clamping block 422 and the second clamping block 423 are correspondingly clamped into the first clamping groove 412 and the second clamping groove 413, respectively, the rear support 30 is limited in rotation and is in the unfolded state relative to the connecting arm 20. When the lock core 42 is driven to retract to the unlocking position by operating the operating member 43, the second circular arc surface 421 is separated from the first circular arc surface 411, and the first clamping block 422 and the second clamping block 423 are respectively withdrawn from the first clamping groove 412 and the second clamping groove 413, the rear support 30 can be rotated to the folding state close to the front support 10 relative to the connecting arm 20.

[0042] As shown in the drawings, Figure 7 The end of the lock seat 41 close to the connecting arm 20 is provided with a first circular arc surface 411 around the rotation axis of the rear support 30. The first circular arc surface 411 is a convex circular arc surface, and the outer periphery of the first circular arc surface 411 is provided with a first clamping groove 412 and a second clamping groove 413 at intervals.

The second circular arc surface 421 is a concave circular arc surface, and the outer periphery of the second circular arc surface 421 is provided with a first clamping block 422 and a second clamping block 423 at intervals. The first clamping block 422 and the second clamping block 423 are respectively arranged at the two ends of the second circular arc surface 421. The first clamping block 422 is arranged at the upper end, and the second clamping block 423 is arranged at the lower end. Both of them protrude towards the lock seat 41. The position of the first clamping groove 412 corresponds to the position of the first clamping block 422, and the position of the second clamping groove 413 corresponds to the position of the second clamping block 423. The first clamping groove 412 is arranged above the second clamping groove 413. The second circular arc surface 421 is in close contact with the first circular arc surface 411. The first clamping block 422 is fitted in the first clamping groove 412, and the second clamping block 423 is fitted in the second clamping groove 413.

[0043] The operating member 43 is used to lock and unlock the lock cylinder 42 and the lock seat 41. When the lock cylinder 42 is locked with the lock seat 41, the first clamping block 422 is clamped in the first clamping groove 412, the second clamping block 423 is clamped in the second clamping groove 413, the outer edge surface is abutted against the inner wall of the second clamping groove 413, and the lower end of the rear leg 30 is unfolded relative to the front leg 10. When unlocked, the lock cylinder 42 is separated from the lock seat 41, and the lower end of the rear leg 30 can be folded towards the front leg 10.

[0044] The first clamping block 422 is protruded from the second arc surface 421, which is protruded upwards and towards the first arc surface 411.

The inner edge surface is connected between the second clamping block 423 and the second arc surface 421, and the outer edge surface is connected between the second clamping block 423 and the bottom side of the lock cylinder 42. The inner edge surface and the outer edge surface intersect, and the second clamping block 423 is a sharp corner structure with an angle less than 60 degrees, for example, 60 degrees, 55 degrees, 50 degrees, or other degrees. During the movement of the portable folding high chair 100 from the unfolded state to the folded state, the operating member 43 drives the lock cylinder 42 to be unlocked with the lock seat 41, the second arc surface 421 is away from the first arc surface 411, the first clamping block 422 is separated from the first clamping groove 412, the second clamping block 423 is separated from the second clamping groove 413, the rear leg 30 can be rotated relative to the front leg 10, and the rear leg 30 is controlled to be folded towards the front leg 10, so that the portable folding high chair 100 can be folded. During the movement of the portable folding high chair 100 from the folded state to the unfolded state, the second arc surface 421 is close to the first arc surface 411, the first clamping block 422 is close to the first clamping groove 412, and the second clamping block 423 is close to the second clamping groove 413, until the second arc surface 421 is abutted against the first arc surface 411, the first clamping block 422 is fitted in the first clamping groove 412, the second clamping block 423 is fitted in the second clamping groove 413, the lock cylinder 42 is locked with the lock seat 41, and the rear leg 30 is unfolded relative to the front leg 10.

[0045] According to the portable folding high chair 100 of the embodiment of the present application, the lock core 42 can be controlled to extend and retract by setting the locking assembly 40, the lock core 42 can move between the locked position and the unlocked position, when the lock core 42 extends to the locked position, the lock core 42 is locked with the lock seat 41, the rear leg 30 is in the unfolded state, when the lock core 42 retracts to the unlocked position, the lock core 42 is unlocked with the lock seat 41, the rear leg 30 is in the folded state, the first clamping block 422 and the second clamping block 423 which are opposite in the clamping direction are arranged on the lock core 42, when the lock core 42 is locked with the lock seat 41, the lock core 42 can be clamped to the lock seat 41 from the opposite direction, which can prevent the lock core 42 from being separated from the lock seat 41, improve the firmness of the lock core 42 and the lock seat 41, and more effectively limit the rotation of the rear leg 30, and improve the reliability of the limiting. Specifically, the included angle between the inner edge surface and the outer edge surface is 45 degrees, the inner edge surface of the second circular surface 421 extends downward in the direction of the first circular surface 411 to form the inner edge surface of the second clamping block 423, the outer edge surface of the second circular surface 421 extends downward in the direction of the first circular surface 411 to form the outer edge surface of the second clamping block 423, the inner edge surface and the outer edge surface intersect to form an included angle, the included angle between the inner edge surface and the outer edge surface is 45 degrees, and the second clamping block 423 is arranged in the sharp angle structure of 45 degrees, which can improve the clamping area of the second clamping block 423 and the second clamping groove 413, improve the reliability of the clamping, and further improve the stability of the cooperation between the lock core 42 and the lock seat 41.

[0046] Further, the junction of the inner edge surface and the outer edge surface is a sharp angle, the outer edge surface extends downward in the direction of the sharp angle, and the included angle between the outer edge surface and the tangent line of the sharp angle is less than 60 degrees. The junction of the inner edge surface and the outer edge surface forms an acute angle structure, and the included angle between the outer edge surface of the second clamping block 423 and the tangent line of the acute angle structure is set to be less than 60 degrees, which can ensure that the second clamping block 423 can smoothly extend into the second clamping groove 413 and be clamped with the second clamping groove 413.

[0047] In some embodiments, as shown in Figures 1-6 the rear end of the connecting arm 20 is provided with a mounting opening, the lock core 42 is located in the connecting arm 20, the lock core 42 extends to the mounting opening when locked, and the lock seat 41 is located at the mounting opening. The connecting arm 20 is provided with a containing space, the lock core 42 is arranged in the containing space, the connecting arm 20 is provided with a mounting opening at one end close to the rear leg 30, the lock core 42 moves back and forth in the containing space, moves away from or towards the mounting opening, the lock core 42 moves towards the mounting opening until it moves to the mounting opening, and cooperates with the lock seat 41 located at the mounting opening, and the lock core 42 is locked with the lock seat 41. The lock core 42 moves away from the mounting opening and separates from the lock seat 41 located at the mounting opening, and the lock core 42 is unlocked with the lock seat 41. This arrangement can save space, make the space layout more reasonable, and also improve the aesthetic degree.

[0048] Specifically, as shown in Figure 7As shown, the lock seat 41 is provided with a clamping block 414, which is located on the side of the second clamping groove 413 away from the first clamping groove 412. When the lock core 42 is unlocked and the rear leg 30 is rotatable, the clamping block 414 can abut against the inner wall of the upper end of the mounting port.

[0049] Specifically, the clamping block 414 extends along the first circular surface 411 towards the second circular surface 421 and downwards, and protrudes from the first circular surface 411. When the lock core 42 is unlocked and the rear leg 30 is rotated to the folded state, the clamping block 414 rotates to the inner wall of the upper end of the mounting port, and the inner wall of the upper end of the mounting port abuts against the protruding clamping block 414. In this way, the rotation range of the rear leg 30 can be limited. When the clamping block 414 abuts against the inner wall of the upper end of the mounting port, the rear leg 30 is stopped by the inner wall of the upper end of the mounting port and stops rotating.

[0050] Further, as shown, Figure 7 The clamping block 414 constitutes the inner wall of the second clamping groove 413, and the outer edge surface of the second clamping block 423 abuts against the clamping block 414 when locked. The side of the clamping block 414 close to the lower end of the first circular surface 411 is connected with the first circular surface 411 to form the second clamping groove 413. When the lock core 42 is locked with the lock seat 41, the acute structure of the second clamping block 423 extends into the second clamping groove 413 to achieve clamping, and the outer edge surface of the second clamping block 423 abuts against the clamping block 414. This arrangement reduces the complexity of the structure, facilitates manufacturing, and increases the clamping area of the second clamping block 423 and the clamping block 414, thereby improving the reliability of clamping.

[0051] In some embodiments, as shown, Figures 1-6 The operating member 43 is rotatably connected to the connecting arm 20, and the operating member 43 is linked with the lock core 42. When the operating member 43 rotates, the lock core 42 is driven to extend and retract. The elastic member 44 is used to drive the lock core 42 to extend towards the lock seat 41.

[0052] Specifically, the operating member 43 is connected to the lock core 42 at an end away from the second arc surface 421, the lock core 42 is provided with an inclined slot at the end away from the second arc surface 421, one end of the operating member 43 is arranged in the inclined slot, and the other end is connected to one end of the connecting arm 20 close to the front leg 10. One end of the operating member 43 is movable in the inclined slot, and movement of the operating member 43 can drive the lock core 42 to move synchronously. The elastic member 44 is connected to the end of the lock core 42 provided with the inclined slot. When the operating member 43 moves towards the connecting arm 20, the lock core 42 moves away from the lock base 41, and at this time, the elastic member 44 is compressed, the lock core 42 is unlocked with the lock base 41, and at this time, the rear leg 30 can be folded relative to the front leg 10. When the operating member 43 moves away from the connecting arm 20, the elastic member 44 drives the lock core 42 to move towards the lock base 41 until the lock core 42 is locked with the lock base 41, and the rear leg 30 can be unfolded relative to the front leg 10. The structure is simpler, the elastic member 44 has an elastic force to drive the lock core 42 to extend outward, the lock core 42 moves towards the lock base 41, and the locking and unlocking of the lock core 42 with the lock base 41 is facilitated, and then the unfolding and folding of the rear leg 30 is controlled.

[0053] Specifically, as shown in Figure 7 The lock base 41 is connected to the connecting arm 20 through the central hole 415, and the lock base 41 is provided with a plurality of spaced weight-reducing holes 416 around the central hole 415. The central hole 415 of the lock base 41 is arranged at the center of the lock base 41, a fastener can be arranged in the central hole 415, the fastener connects the lock base 41 and the connecting arm 20 together, the weight-reducing holes 416 are arranged around the central hole 415, the plurality of weight-reducing holes 416 are arranged at intervals, and the size and shape of the weight-reducing holes 416 are not limited. In this way, the weight of the lock base 41 can be reduced, the material can be saved, the fastening of the lock base 41 and the connecting arm 20 can be ensured, and the rotation of the lock base 41 around the connecting arm 20 can be ensured.

[0054] The portable folding high chair 100 in the application comprises a seat 50, which is a seat for a child.

[0055] Specifically, the seat 50 is connected to the top of the front leg 10, so that the child can sit at a higher position.
