Abstract
The utility model provides a folding type crank arm mechanism, which is characterized by the inclusion of an upper connecting rod, a lower connecting rod and a sliding block, wherein the upper connecting rod is hinged with the lower connecting rod; the sliding block is hinged at the bottom of the lower connecting rod; the sliding block is pushed to conveniently drive the upper connecting rod and the lower connecting rod which are hinged together to finish the folding and the expansion and to drive a folded piece which is hinged with the upper connecting rod and the lower connecting rod to finish the folding and the expansion synchronously; and since the two connecting rods are arranged, the utility model has the characteristics of favorable stability, fixedness, simple structure, firmness, durability, convenient manufacture and maintenance, low cost and the like, thereby being an ideal folding mechanism.
Description
Technical field
The utility model relates to a kind of crank arm mechanism, and particularly a kind of collapsible crank arm mechanism belongs to the linkage mechanism technical field.
Background technique
At present in some special occasions, tend to use such as facilities such as safety warning light, multimedia display screen or poster versions, larger-size for some and can fold beacon, display screen and poster version, how being convenient to use fold mechanism folds and sets up, and set up the stable and steadiness that how to guarantee mechanism, just become an one and another difficult problem.Particularly on expressway, if traffic accident takes place, just need to use and eye-catching and have the collapsible beacon of large area light emitting body, so just good caution and indicative function can be arranged.And, lose indicative function in case the folding beacon that sets up owing to blow or other factors, causes folding suddenly gathering the in, will cause immeasurable potential safety hazard to the scene of the accident.Therefore be necessary prior art is improved.
Summary of the invention
For solving existing folding beacon, display screen, poster version etc., stable and steadiness is poor because of fold mechanism, and set up problem such as difficulty, it is a kind of simple in structure that the utility model provides, stable performance, reliable, and durable collapsible crank arm mechanism.
The utility model is finished by following technical proposal: a kind of collapsible crank arm mechanism, it is characterized in that comprising upper and lower two connecting rods that are hinged, and the slide block that is articulated in the lower link bottom.
Described slide block is made as the slide block of bottom belt wheel, perhaps is made as the bottom and is the slide block of smooth flat, perhaps the slide block of bottom band ball, and link to each other with power-driven machine, so that under power-driven machine drives, slide block is moved back and forth, thereby drivening rod is finished folding and stretching, extension around articulated elements.
Described slide block is provided with support platform, behind the folding device that need fold with box lunch, the one end is placed on this support platform.
In described upper and lower two connecting rods that are hinged, the length of last connecting rod is less than the length of lower link, the upper end of last connecting rod is hinged with the last part top that is folded part that is hinged mutually by articulated elements, the middle part of lower link is hinged with following the bottom that is folded part that is hinged mutually by articulated elements, following the lower end that is folded part is hinged by articulated elements and base, so that moving of the slide block by the lower link lower end, two connecting rods are driven be folded part and finish folding.
Described two caution light signs that are folded part for band light emitting diode on it are hinged by articulated elements between two caution light signs, and wherein, the bottom of following caution light sign is hinged by articulated elements and base.
The described billboard that is folded part for band advertisement picture on it is hinged by articulated elements between two billboards, and wherein, the bottom of following billboard is hinged by articulated elements and base.
Describedly be folded the sign board that part also can be other form.
The utlity model has following advantage and effect: adopt such scheme, only need to promote slide block, just can drive upper and lower two connecting rods that are hinged easily and finish folding and stretching, extension, drive the part that is folded that is hinged with upper and lower connecting rod simultaneously and finish folding synchronously and stretching, extension, owing to only adopted two connecting rod settings, therefore have good stable and steadiness, have simple in structurely, sturdy and durable simultaneously, make, easy to maintenance, characteristics such as cost is low are a desirable fold mechanism in fact.
