Problems solved by technology
[0002] Hinges are commonly used components in daily life and industrial production, but the current hinges have simple structures, no angle locking function, and single functions, which also limit the scope of application of hinges
[0003] Ladders are a kind of climbing tools that people often use in daily life. At present, there are more ladders and straight ladders on the market. These two kinds of ladders have certain limitations in height and use.

Embodiment Construction
[0029] Such as Figure 1~11 As shown, a lever-type multi-position hinge mechanism includes a first hinge arm 15 and a second hinge arm 16 whose ends are hinged together, and the first hinge arm 15 and the second hinge arm 16 are hinged The end has a disc portion 17 hinged at the center of the circle; the edge portion of the disc portion of the first hinge arm 15 is provided with a limit groove 18 at intervals along the circumferential direction, and the second hinge arm 16 is provided with a spring that can be inserted into it. The limit slider 12 in the limit slot 18 and the toggle lever 13 used to move the limit slider 12 out of the limit slot, push the toggle lever to make the limit slider exit from the slot, and then adjust the first The included angle between the hinge arm 15 and the second hinge arm 16 and the limit sliders are matched with different slots to obtain hinge mechanisms with different opening angles.
[0030] When the angle is changed, the operation of releasi...

The invention relates to a poking rod type multi-clamping hinge mechanism and application of the poking rod type multi-clamping hinge mechanism. The mechanism comprises a first hinge arm and a secondhinge arm, wherein one end of the first hinge arm and one end of the second hinge arm are hinged together, and the hinged ends of the first hinge arm and the second hinge arm are provided with disc parts with circle centers hinged. Limiting grooves are formed in the edge portion of the disc part of the first hinge arm at intervals along the circumferential direction, and limiting sliding blocks capable of being clamped into the limiting grooves under the action of springs and poking rods used for poking the limiting sliding blocks out of the limiting grooves are arranged on the second hinge arm. According to the poking rod type multi-clamping hinge mechanism, adjustment at multiple angles can be achieved, a locking function is achieved, the function of a hinge is enriched, the use range ofthe hinge is enlarged, use is convenient and fast, operation is easy, and the structure is stable and reliable. The poking rod type multi-clamping hinge mechanism is connected and applied to a ladder, so that the ladder can be used as a straight ladder or a herringbone ladder and is convenient and fast to adjust according to the height.
Description
Technical field [0001] The invention relates to a lever type multi-position hinge mechanism and its application. Background technique [0002] Hinges are commonly used parts in daily life and industrial production, but the current hinges are simple in structure, do not have an angle locking function, and have a single function, which also limits the scope of application of the hinge. [0003] Ladder is a kind of climbing tool that people often use in daily life. At present, there are more herringbone ladders and straight ladders in the market. These two types of ladders have certain limitations in height and usage. Summary of the invention [0004] In view of this, the object of the present invention is to provide a lever-type multi-detent hinge mechanism with an angle locking function that is convenient to use and its application. [0005] The present invention adopts the following scheme to achieve: a lever-type multi-detent hinge mechanism, comprising a first hinge arm and a secon...
