[0028] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.
[0029] Refer to Figures 1-5, A folding stool with a locking structure, comprising: a first panel 100, a second panel 101, a stool leg structure 102, a locking pin 103, a locking groove 104, and a reset structure. The first panel 100 and the second panel 101 are hinged to each other. A handle 106 is provided on the second panel 101, and a groove 107 for accommodating the handle 106 is formed on the first panel 100. The stool leg structure 102 includes two support plates 108 respectively hinged to the first panel 100 and the second panel 101. Side plates 109 are hinged to both sides of the support plates 108, and two adjacent side plates 109 are hinged to each other. Thus, the first panel 100 and the second panel 101 can form a folded first state and an unfolded second state. In the first state, a folded state is formed, which is convenient for carrying and storage. In the second state, the first panel 100, the second panel 101, the support plates 108, and the side plates 109 form a three-dimensional structure support state.
[0030] The locking pin 103 is arranged on the first panel 100. An installation sleeve 110 is fixedly connected to the first panel 100, and a sliding groove 111 for accommodating the sliding of the locking pin 103 is formed on the installation sleeve 110. One end of the locking pin 103 slides along the sliding groove 111 and is inserted into the groove 107. The locking groove 104 is formed on one side of the handle 106. The locking pin 103 is inserted into the locking groove 104 to lock the first panel 100 and the second panel 101. An installation groove 112 is formed on the locking pin 103, and a push button 113 is installed in the installation groove 112. A through groove for the push button 113 to pass through is formed on the first panel 100, and the movement of the locking pin 103 is driven by pushing the push button 113.
[0031] The reset structure includes: a first spring 114, a hinged rod 115, and an unlocking mechanism. The first spring 114 is arranged in the sliding groove 111. Two ends of the first spring 114 respectively abut against the locking pin 103 and the inner wall of the sliding groove 111. A connecting frame 117 is fixedly arranged on the installation sleeve 110, and the hinged rod 115 is rotatably arranged on the connecting frame 117.
[0032] The hinged rod 115 has a first end 118, a second end 119, and a rotating part 120 located between the first end 118 and the second end 119. A rotating shaft is arranged on the rotating part 120, and the rotating shaft is rotatably arranged on the connecting frame 117. A buckle 121 is fixedly arranged at the first end 118 of the hinged rod 115, and a clamping groove 122 for the buckle 121 to be embedded is formed on the locking pin 103.
[0033] The unlocking mechanism includes: a second spring 123 and an arc-shaped protrusion 124. Both ends of the second spring 123 are respectively abutted against the mounting sleeve 110 and the hinge rod 115. A mounting cylinder is fixed on the mounting sleeve 110, and one end of the second spring 123 is inserted into the mounting cylinder for positioning. The arc-shaped protrusion 124 is fixedly arranged on the second panel 101, and the second spring 123 abuts against the second end 119. When the first panel 100 and the second panel 101 are in the first state, the arc-shaped protrusion 124 abuts against the second end 119 of the hinge rod 115, causing the hinge rod 115 to deflect around the rotating part 120.
[0034] One end of the locking pin 103 inserted into the locking groove 104 has a smoothly transitioning arc-shaped surface 125. When it is necessary to adjust the first panel 100 and the second panel 101 from the first state to the second state, the handle 106 squeezes the locking pin 103 through the arc-shaped surface 125. The locking pin 103 slides in the sliding groove 111, and under the action of the first spring 114, the locking pin 103 is inserted into the locking groove 104.
[0035] Working process: When it is necessary to fold the stool, push the push button 113 to drive the locking pin 103 to move and compress the first spring 114. When the locking pin 103 disengages from the locking groove 104, the buckle 121 is snapped into the card slot 122 under the action of the second spring 123 to limit the locking pin 103 and prevent the locking pin 103 from protruding. When the first panel 100 and the second panel 101 are folded, the arc-shaped protrusion 124 abuts against the second end 119 of the hinge rod 115 and squeezes the second end 119, causing the hinge rod 115 to deflect around the rotating part 120, and the buckle 121 disengages from the card slot 122, enabling the locking pin 103 to protrude under the action of the first spring 114. When it is necessary to unfold and install the first panel 100 and the second panel 101, the handle 106 squeezes the locking pin 103 through the arc-shaped surface 125. The locking pin 103 slides in the sliding groove 111, and under the action of the first spring 114, the locking pin 103 is inserted into the locking groove 104.
[0036] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features having similar functions disclosed in the embodiments of the present disclosure.
