AI Technical Summary
Existing folding chairs take up a lot of space in the bathroom and are difficult to fold up. When the damping structure fails, it is easy to hit the feet or damage the floor. In addition, the operation is inconvenient, which affects the user experience.
A self-locking folding chair is designed. Through the cooperation between the push rod and the self-locking slot, a spring is used to drive the push rod into the self-locking slot to achieve self-locking. A push button controls the push rod to disengage from the self-locking slot to achieve unfolding. A damper is combined to control the unfolding speed. The chair has a simple structure and low cost.
The folding chair can be folded and unfolded safely and conveniently, thus avoiding misoperation, improving space utilization, and reducing operation risks and noise pollution.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.
[0026] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0027] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
[0028] With reference to the drawings of the specification, a self-locking folding chair comprises a bracket 10 and a seat plate 20 that can be fixedly connected to a wall. The rear side of the seat plate is hinged to the bracket, and a fixing rod 30 is provided on the bracket. When in use, the fixing rod does not rotate. The fixing rod is provided with a self-locking groove 31, which can be vertical or vertically offset by some angles; it also includes a push rod 40 that can move relative to the seat plate, and a spring 41 is provided between the push rod and the seat plate. The spring can drive the push rod to move toward the rear side of the seat plate, and the push rod can rotate synchronously with the seat plate relative to the bracket; after the seat plate is folded close to the wall, the rear end of the push rod can be inserted into the self-locking groove so that the seat plate cannot rotate relative to the bracket. At this time, under the action of the spring, the push rod cannot be withdrawn from the self-locking groove, thereby achieving and maintaining a self-locking state. The folding chair is in a folded state, which increases the space in the shower area; when the seat plate is unfolded away from the wall, the rear end of the push rod is separated from the self-locking groove, which can achieve an unfolded state for a shower user to sit.
[0029] Preferably, the folding chair further comprises a push button 50, which can drive the push rod to move toward the front side of the seat plate, so that the rear end of the push rod is withdrawn from the self-locking groove, thereby enabling the seat plate to rotate relative to the bracket. In other words, the push rod can be disengaged from the self-locking groove by applying additional force, thereby enabling the folding chair to change from a folded to an unfolded state. The folding chair further comprises a fixing plate 60 that can be connected to the seat plate. The front end of the push rod can be arranged between the fixing plate and the seat plate. The fixing plate and the push button are both arranged at the front end below the seat plate. The fixing plate is provided with an opening 61 that can adapt to the push button. The outer periphery of the push rod is provided with a first protruding ring 42, and the push button is provided with a second protruding ring 51. The second protruding ring can be sleeved on the outer periphery of the push rod. The rear end surface of the first protruding ring can abut and cooperate with the front end surface of the second protruding ring, so that the push button drives the push rod to move toward the front side of the seat plate.
[0030] Furthermore, at least one connecting piece 70 is provided at the lower end of the seat plate, and the push rod can be inserted between the connecting piece and the seat plate so that the push rod can move forward and backward relative to the seat plate. Two connecting pieces are drawn in the figure.
[0031] Furthermore, the bracket 10 includes a fixing plate 11 that can be fixed to the wall, hinges 12 are distributed on both sides of the front side of the fixing plate, the fixing rod is arranged between the two hinges, and dampers 32 are provided at both ends of the fixing rod. A support plate 21 is provided on the periphery of the damper, and the support plate can be fixedly connected to the lower end surface of the seat plate, so that the speed of the seat plate when unfolded will not be too fast. The use of the damper is similar to the prior art and will not be elaborated here.
[0032] Preferably, the device further comprises a support foot 80, which can be hinged to the front side of the support plate, and a connecting rod 90 which can be located below the support plate, with the front end of the connecting rod hinged to the middle of the support foot and the rear end of the connecting rod hinged below the hinge, while the fixing plate and the push button are located on the front side of the support foot.
[0033] The utility model is more specific: the left and right hinges are fixed to the fixing plate to form a bracket, and then the bracket is fixed to the wall; the left and right hinge parts are connected with the fixing rod, and the fixing rod has a self-locking groove; the top rod is connected to the bottom of the seat plate, and a certain restriction is imposed so that the top rod can first slide smoothly back and forth on the seat plate; a spring is assembled on the top rod, and is assembled together with a push-button; pushing the push-button drives the top rod to move upward (the front side of the seat plate after folding), at which time the top rod disengages from the self-locking groove, and the folding chair can be unfolded and put down; when the folding chair is folded up, the top rod automatically locks into the self-locking groove of the fixing rod; components such as push buttons are arranged at the bottom of the seat plate. When the folding chair is folded up against the wall, the push buttons face the user, and the user can easily see and operate them; after the folding chair is opened, the push buttons face downward, which will not affect showering and sitz bathing.
[0034] The above description shows and describes the preferred embodiments of the present application, as mentioned before, it should be understood that the present application is not limited to the form disclosed herein, should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the application conceived herein, through the above teaching or related technical or knowledge. And the changes and variations made by the person skilled in the art do not deviate from the spirit and scope of the present application, and should be within the protection scope of the claims of the present application.
