DETAILED DESCRIPTION
[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0027] Reference Figures 1 to 6 As shown, the switch cabinet 1 with multiple door opening angles of the present invention comprises: a cabinet body 11, a cabinet door 12 and a door limiter 100, etc.
[0028] The cabinet body 11 forms an inner cabinet space for accommodating electrical components; the cabinet door 12 is rotatably connected to the cabinet body 11; and the door limiter 100 is rotatably connected to the cabinet body 11 and the cabinet door 12 respectively.
[0029] The door limiter 100 includes: a first hinge seat 101, a second hinge seat 102, a first connecting rod 103, a second connecting rod 104, a third connecting rod 105, a limit clamping plate 106, a limit seat block 107, a limit clamping block 108, a trigger connecting rod 109, and an elastic member 110.
[0030] As a specific solution, the first hinge seat 101 is fixedly connected to the cabinet body 11; the second hinge seat 102 is fixedly connected to the cabinet door 12; the first connecting rod 103 is rotatably connected to the first hinge seat 101; the second connecting rod 104 is rotatably connected to the first connecting rod 103; the third connecting rod 105 is rotatably connected to the second connecting rod 104; the limiting clamp plate 106 is rotatably connected to the first connecting rod 103; the limiting seat block 107 is mounted on the limiting clamp plate 106 and rotates with the third connecting rod 105; the limiting block 108 is rotatably and slidingly connected to the limiting seat block 107.
[0031] The limiting card plate 106 is provided with a plurality of repeatedly arranged limiting teeth 111. When the limiting card block 108 slides to the embedded position, the limiting card block 108 is embedded between two limiting teeth 111; when the limiting card block 108 slides to the unlocked position, the limiting card block 108 disengages from the limiting teeth 111.
[0032] In this way, the cooperation between the limit block 108 and the limit tooth 111 is equivalent to forming a ratchet system, thereby limiting the one-way opening of the door and blocking the relative rotation of the main cabinet door 12 when closing the door, thereby ensuring that people are not clamped.
[0033] As a preferred solution, the first connecting rod 103 may adopt a double connecting rod structure.
[0034] Reference Figures 2 to 4 As shown, in some embodiments, the second connecting rod 104 is rotatably connected to the middle section of the first connecting rod 103; the limiting clamping plate 106 and the first hinge seat 101 are respectively rotatably connected to the two ends of the first connecting rod 103. The second connecting rod 104 and the limiting seat block 107 are respectively rotatably connected to the two ends of the second connecting rod 104. In this way, as the connecting rods rotate, the door opening angle can be increased and the door opening angle can be limited at the same time.
[0035] In some embodiments, the limiting clamping plate 106 forms an arc-shaped hollow track 112, and the limiting latching tooth 111 is disposed in the hollow track 112. The limiting latching tooth 111 is configured as a one-way latching tooth.
[0036] In some embodiments, the limiting seat block 107 is provided with a seat hole 113 for the limiting clamping plate 106 to pass through; the limiting clamping tooth 111 is arranged in the seat hole 113 .
[0037] In some embodiments, the trigger rod 109 is rotatably connected to the limit seat block 107; the limit block 108 is rotated to the end of the trigger rod 109, and the other end of the trigger rod 109 extends out of the limit seat block 107. The trigger rod 109 can be linked with the handle or handle button on the cabinet door 12, so that the limit block 108 can be disengaged from the limit of the limit tooth 111 when the user closes the door.
[0038] In some embodiments, the elastic member 110 is disposed between the trigger link 109 and the limit block 108 to bias the trigger link 109 so that it drives the limit block 108 to be embedded in the limit tooth 111. Preferably, the elastic member 110 is a coil spring. In this way, the limit block 108 can be reset when the external force is lost.
[0039] In some embodiments, the first hinge seat 101 is mounted to the end of the limit clamping plate 106. This can maximize the door opening angle.
[0040] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. 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 a specific combination of the above technical features, but 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 above features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
