Abstract
The utility model relates to a measuring tape which is composed of a driving ruler-belt wheel which is arranged in a ruler casing, a driven ruler-belt wheel, the transition belt of a winding ruler-belt wheel, a ruler belt, a gear reduction assembly, a spring, and a stopping mechanism. The utility model has the advantages of convenient portability, high safety.
Description
The utility model relates to a kind of length-measuring appliance.
Existing various tape measure is generally circle or square, steel.Shortcoming is to carry inconvenience, easily lose, heavier, the expense steel, the cost height.The anthropometric tape of existing tailoring is that plastics system mark shortcoming is to carry inconvenience, makes winter and hardens.
The purpose of this utility model provides a kind of above-mentioned two kinds of chi shortcomings that overcome, the tape measure that makes it to unite two into one.
The purpose of this utility model realizes by following scheme, initiatively chi belt wheel and driven chi belt wheel are installed in the chi shell, and a transitional zone is being twined two chi belt wheels, and an end of chi band is fixed on the transitional zone, the other end twines transitional zone after a few, stretches out the chi shell by outlet.Initiatively the chi belt wheel is connected by the gear shaft of gear reduction assembly with fixing spring one end, and the other end of spring is fixed on the chi shell.The other end at gear shaft has a stopping gear that is meshed with arresting lever (pen is not), and the slip arresting lever is installed in the chute of opening on the chi shell.When pulling chi band, the chi band drives the driving tooth belt wheel and rotates, and by the gear reduction assembly spring on the gear shaft is rotated and stored energy.When moving Len req to, promote arresting lever (pen is not) downwards and brake, the chi band just can rest on required length.In the time will regaining the chi band, upwards promote arresting lever, under the energy of spring, the chi band is recovered in the chi shell.
Characteristics such as pen type circle chi of the present utility model has easy to carry, is difficult for losing, and is safe in utilization because most of parts adopt rigid plastic, can be saved a large amount of steel.
Below in conjunction with accompanying drawing the utility model is described in detail, but protection domain of the present utility model is not limited to this embodiment.
Fig. 1 is the cut-open view of the utility model embodiment.
Fig. 2 is the cut-open view along the II among Fig. 1-II line.
Fig. 3 be among Fig. 1 A to the rotation partial sectional view.
With reference to attached Fig. 1 and 2, in the double-body bike chi shell of forming by upper and lower two chi shells 1, initiatively chi belt wheel 5 and driven chi belt wheel 4 are installed, transitional zone 3 is being twined two chi belt wheels 4 and 5.Transitional zone 3 and chi belt wheel 4 and 5 can be the flat belt drive mechanisms, but in order to increase the transmission effect, preferably adopt synchronizing jugged pulley transmission structure as shown in the figure.One end of chi band 2 is bonded on the transitional zone 3, and chi band 2 stretches out from the openings 16 on the chi shell twining a few backs on the transitional zone 3, is equipped with in the outer end of chi band 2 that chi colludes in case the chi band is all withdrawn in the chi shell 1.End at active chi belt wheel 5 has a pinion wheel 6, and pinion wheel 6 and gear wheel 7 engagements are with the pinion wheel 8 and gear wheel 9 engagements on the gear wheel 7 same axles.Formed a gear reduction assembly by pinion wheel 6,8 and gear wheel 7,9 like this, its reduction gear ratio can be between 1:3～1:6.Gear shaft 10, gear wheel 9 and stopping gear 18 form one, and an end of spring 12 is tightly fixing with screw 11 behind square section in the middle of the gear shaft, and the other end of spring 12 can adopt the company of extension or be fixed on the thickening boss 19 on the chi shell 1 with the screw ways of connecting.Arresting lever (pen not) 14 is meshed with the stopping gear of gear shaft 10 1 ends, and arresting lever 14 can slide in the chute on the chi shell 1 13.Two chi shells connect with self-tapping screw 15.Chi shell, arresting lever are made with rigid plastic, and chi belt wheel, gear reduction assembly and stopping gear and its axle separately adopts single injection-molded, makes it to constitute one.Chi band 2 can adopt materials such as nylon.
At chi shell one end of the present utility model, the shaft of a writing brush that can the various nibs of mounting strap is to realize the multi-functional purpose of a chi.
