Abstract
The utility model discloses a counter, comprising the main parts of a character code disk, a turntable, a double-side ratchet wheel, a detent, an elastic shaft, a stopping block, etc. When a shaft turns a certain angle, a ratchet wheel detent mechanism and a groove wheel mechanism make the character code disk turn a character. Because the teeth on the character code disk and the teeth on the double-side ratchet wheel are in opposite direction, the character code disk and the double-side ratchet wheel both can only relatively turn along one direction and can not make reverse rotation. Thus the counter can not zero-reset and is suitable for the equipment which needs to record the precise times of a certain action. Although the manufacture precision of the parts of the utility model is not high, the working performance is much reliable. The entire structure is compact, and the appearance is delicate.
Description
The utility model relates to a kind of mechanical counter.
The present counter that uses, be provided with reset button, be used for needing duplicate measurements or surveyed one and at once the next one is measured the device of often from the beginning counting, as long as click reset button, the indication of the lettered dial of counter is prepared next counting with regard to vanishing.Types such as general sound-track engraving apparatus and video recorder all use this counter.But at some special industry such as some primary cut-outs of electric industry system, its access times have regulation, if use above-mentioned register to write down the number of starts of primary cut-out, just are difficult to judge how many true number of times that high-voltage switch gear starts is.Give between manufacturing firm and the users easily and cause contradiction.
The purpose of this utility model is the deficiency that overcomes above-mentioned counter, and designs a kind of counter of being made up of main part such as ratchet and pawl arrangement, Geneva mechanism and lettered dial, and reliable recording the ruuning situation of equipment; The number of starts of image height voltage breaker etc.
The utility model content, it is made up of lettered dial, wheel disc, spring, ratchet and pawl arrangement and Geneva mechanism; Be fixed with disk [ 8 ] on the axle [ 7 ], disk [ 8 ] is provided with link stopper [ 13 ], and the dish [ 6 ] of band elastic pawl [ 16 ] is contained on the disk [ 8 ]; The engagement of the tooth on two-sided ratchet [ 5 ] right side and ratchet [ 16 ], the tooth on its left side is meshed with tooth [ 11 ] on the wheel disc [ 3 ]; The link stopper groove [ 10 ] of dish [ 3 ] engages with the link stopper [ 13 ] of disk [ 8 ], and the two ends of spring [ 2 ] are separately fixed on frame [ 1 ] and the axle [ 7 ]; The cylindrical of two-sided ratchet [ 5 ] is provided with tooth [ 12 ], and tooth [ 12 ] meshes with the internal tooth of lettered dial [ 4 ]; The double wedge [ 17 ] that the left side of lettered dial [ 4 ] is provided with on groove [ 15 ], it and the wheel disc [ 9 ] is formed Geneva mechanism.
Advantage: the utility model is the improvement to the counter of present use, its the most outstanding advantage is the following equipment that will examine of energy reliable recording or the number of run of device, secondly Geneva mechanism and ratchet and pawl arrangement is simple in structure, manufacturing accuracy is less demanding, but reliable working performance, the 3rd the utility model compact conformation is elegant in shape.

Below in conjunction with description of drawings the utility model embodiment, the utility model can be divided into support and movement two parts, and movement is made up of critical parts such as lettered dial, two-sided ratchet, frame, spring, ratchet, axle and blocks; Frame [ 1 ] comprises chassis and two cylinders, integral molded plastic moulding; Bore the tap out hole on the cylinder, wheel disc [ 3 ] is fixed on the frame [ 1 ] by screw; Lettered dial [ 4 ] and all the other several lettered dials are installed between the base of wheel disc [ 3 ] and frame [ 1 ]; One end of spring [ 2 ] is contained on the cylinder of frame [ 1 ], the other end turns to the spiral that connects airtight, be conical, it and the tight cover of axle [ 7 ], play a part fixing, little axle also is housed on the chassis of frame [ 1 ], on little axle wheel disc [ 9 ] is installed, the double wedge [ 17 ] of wheel disc [ 9 ] right-hand member forms Geneva mechanism with the groove [ 10 ] of corresponding lettered dial; The double wedge [ 18 ] of wheel disc [ 9 ] left end and the engagement of the internal tooth [ 14 ] of lettered dial [ 4 ]; The tooth [ 11 ] of wheel disc [ 3 ] is opposite with the tooth direction on two-sided ratchet [ 5 ] left side, and both can only unidirectional motion, so counter can not arbitrarily return zero, the tooth on two-sided ratchet [ 5 ] right side engages with ratchet [ 16 ] on the dish [ 6 ]; Two-sided ratchet [ 5 ] cylindrical is provided with tooth [ 12 ], the internal tooth engagement of it and lettered dial [ 4 ]; Wheel disc [ 3 ] is gone up block groove [ 10 ] and is engaged with block [ 13 ], and the central angle of block groove [ 10 ] is the twice of block [ 13 ]; Disk [ 8 ] is fixed on the axle [ 7 ], and dish [ 6 ] and two-way ratchet [ 5 ] all are sleeved on the cylindrical of block [ 13 ], marks 0,1 on the cylindrical of lettered dial uniformly, ten numerals of 2......9.When the corresponding angle of a numeral of axle [ 7 ] translocation, disk [ 8 ] rotates with ratchet [ 16 ], driving two-sided ratchet [ 5 ] rotates, at this moment spring [ 2 ] produces elastic deformation, when axle [ 7 ] rotate in place, lettered dial [ 4 ] has rotated a numeral, because the effect of the restoring force of spring [ 2 ], make axle [ 7 ], disk [ 8 ] and ratchet [ 16 ] be turned back to original position together, for feeding is next time got ready.Movement is contained in support [ 19 ] lining, and with spring collar snap in the axle [ 7 ] annular groove in locate.Support [ 19 ] top is clear glass, so that observe the numeral of counter at any time, has done via hole on the base plate, so that counter is installed on the use equipment.
