Abstract
The utility model discloses a mechanical meter counter in the field of length measuring instrument, comprising a meter counting pulley, a tightening pulley and a lifting presser bar mechanism. The tightening pulley and the lifting presser bar mechanism are connected, and the meter counting pulley and the tightening pulley are axially arranged in parallel. The tightening pulley and the meter counting pulley are provided with two, respectively. And two tightening pulleys are transimissibly connected with a first synchronous belt, and two meter counting pulleys are transimissibly connected with a second synchronous belt. When running, a cable is clamped between the first synchronous belt and the second synchronous belt. The lifting presser bar mechanism can enable two tightening pulleys and two meter counting pulleys to clamp the synchronous belt and the cable. The cable is pulled at one end, and two meter counting pulleys are rotated synchronously to measure the length of the pulled cable. The contact area of the first and the second synchronous belts and the cable is large and friction is also large, therefore the cable is not easy to skid and high speed pulling can be carried out, then speed of meter counting is big and the measuring accuracy is high. The mechanical meter counter can be applicable to length measurement for a slender body, such as cable, rope, thread and so on.
Description
Technical field
The utility model relates to a kind of measuring appliance, particularly a kind of meter counter.
Background technology
In the prior art, a kind of mechanical meter counter is arranged, its structure mainly includes rice counting wheel, straining pulley and lifting hold-down mechanism, straining pulley links to each other with the lifting hold-down mechanism, rice counting wheel and straining pulley axially parallel are provided with, the lifting hold-down mechanism can be pressed on straining pulley on the rice counting wheel, as clamping one cable between rice counting wheel and straining pulley, then by a short distractor at cable, can make straining pulley and rice counting wheel rotate simultaneously, when rice counting wheel rotates, by detecting the number of turns that rice counting wheel rotates, the length of the cable that can obtain pulling out, the mensuration of realization cable length.Its weak point is: because cable grip is held between rice counting wheel and the straining pulley, cable is shape linearly, rice counting wheel, straining pulley are rounded, surface of contact each other is little, the friction force that produces is also smaller, can only carry out metering at a slow speed and measure, as the quick traction cable, then be easy to generate relative slip between cable and the rice counting wheel, thereby cause error of meter counter.
The utility model content
The purpose of this utility model provides a kind of mechanical meter counter, makes its measuring speed fast, and error is little.
The purpose of this utility model is achieved in that a kind of mechanical meter counter, comprise rice counting wheel, straining pulley and lifting hold-down mechanism, straining pulley links to each other with the lifting hold-down mechanism, rice counting wheel and straining pulley axially parallel are provided with, described straining pulley and rice counting wheel are respectively equipped with two, between two straining pulleys through being with one to be in transmission connection synchronously, between two rice counting wheels through being with two to be in transmission connection synchronously.
During the utility model work, cable grip is held in is with one and be with between two synchronously synchronously, the lifting hold-down mechanism can make two straining pulleys and two rice counting wheels to be with synchronously with cable and clamp together, end pull-in cable at cable, two rice counting wheels rotate synchronously, two straining pulleys also rotate synchronously, and with one and equal with two linear velocity synchronously, rice counting wheel can be measured the length of the cable that pulls out synchronously; Compared with prior art, in the utility model, because synchronously with one and big with two synchronously with the contact area of cable, friction force each other is also big, and in distraction procedure, cable is difficult for skidding, can carry out the high speed traction, make the fireballing while of metering that measuring accuracy is also high; This device can be used for the length metering of slender bodies such as cable, rope, line.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As Fig. 1, be a kind of mechanical meter counter, it mainly is made up of rice counting wheel 2, straining pulley 3 and lifting hold-down mechanism 6, straining pulley 3 links to each other with lifting hold-down mechanism 6, rice counting wheel 2 and straining pulley 3 axially parallel settings, described straining pulley 3 and rice counting wheel 2 are respectively equipped with two, between two straining pulleys 3 through being with one 1 to be in transmission connection synchronously, between two rice counting wheels 2 through being with 25 to be in transmission connection synchronously.
During work, cable 3 is clamped in is with one 1 and be with between 25 synchronously synchronously, lifting hold-down mechanism 6 can make two straining pulleys 3 and two rice counting wheels 2 will be with synchronously with cable 3 and clamp together, end pull-in cable 3 at cable 3, two rice counting wheels 2 rotate synchronously, two straining pulleys 3 also rotate synchronously, and with one 1 and equal with 25 linear velocity synchronously, rice counting wheel 2 can be measured the length of the cable 3 that pulls out synchronously; Because with one 1 and big with the contact area of cable 3 with 25 synchronously, friction force each other is also big synchronously, in distraction procedure, cable 3 is difficult for skidding, and can carry out the high speed traction, makes the fireballing while of metering that measuring accuracy is also high.
Claims (1)
