Abstract
The utility model discloses a hand long chi changes speed, including shell, buffer spring, rule core dish, outer cap, handle seat and handle, buffer spring installs on the shell, and shell and outer cap lock, rule core dish lie in and the rule core dish links to each other with buffer spring between shell and the outer cap, are provided with rule core dish gear on the rule core dish, rule core coil and outer cap between be provided with the apron, the externally mounted of outer cap has the handle seat, is provided with handle seat gear on the handle seat, the one end of handle is passed through the handle cap and is installed cap outside, the other end of handle is installed on the handle seat, handle seat gear and rule core coil the gear and mesh mutually. The device simple structure, reasonable in design, easy operation is convenient, only needs turning handle, and the handle drives handle seat gear revolve, thus handle seat gear band movable auxiliary scale core dish gear revolve takes movable auxiliary scale core dish to rotate, can realize receiving and releasing the chi area, small friction, and it is laborsaving when receiving and releasing the chi area, simple structure 0.
Description
Technical field
This utility model relates to a kind of ruler, specifically a kind of hand long chi of speed change.
Background technology
Ruler is a kind of survey tool, generally adopts tape measure and hand long chi when measuring long-range data, and tape measure is generally used in measurement distance, and hand long chi is a kind of instrument for measuring distance.Hand long chi is the survey tool often used in daily life, commonly used at building field and finishing field, one of indispensable instrument of Ye Shi family.Difference according to ruler material, hand long chi can be divided into the hand long chi of steel, the hand long chi of glass fibre and the hand long chi of plastics.Although current existing hand long chi meets the user demand of people, but with hand start to shake long chi time frictional force very big, relatively elaborate during folding and unfolding tape, these are all that user brings inconvenience.
Utility model content
The purpose of this utility model is in that to provide a kind of hand long chi of speed change, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of hand long chi of speed change, including shell, buffering spring sheet, chi core dish, casing cover, handle set and hands handle, described buffering spring sheet is arranged on shell, shell fastens with casing cover, chi core dish between shell and casing cover and chi core dish be connected with buffering spring sheet, chi core dish is provided with chi core dish gear, it is provided with cover plate between chi core dish and casing cover, the outside of casing cover is provided with handle set, handle set is provided with handle set gear, one end of handle is arranged on outside casing cover by handle cap, the other end of handle is arranged on handle set, handle set gear and chi core dish gear are meshed.
As further program of the utility model: handle is arranged on handle set by straight pin.
As further program of the utility model: handle and handle cap adopt rivet locking.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, reasonable in design, simple to operation, only need turning handle, handle strip fixed handle seat pinion rotation, handle set gear driven chi core dish pinion rotation, thus driving chi core dish to rotate, can realize folding and unfolding tape, and frictional force is little, during folding and unfolding tape laborsaving, result of use is good.
Accompanying drawing explanation
Fig. 1 is the explosive view of the hand long chi of speed change.
Fig. 2 is the external structure schematic diagram of the hand long chi of speed change.
Fig. 3 is the sectional view of the hand long chi of speed change.
Wherein: 1-shell, 2-buffering spring sheet, 3-chi core dish, 31-chi core dish gear, 4-cover plate, 5-casing cover, 6-handle set, 61-handle set gear, 7-handle cap, 8-rivet, 9-handle, 10-straight pin.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-3, a kind of hand long chi of speed change, including shell 1, buffering spring sheet 2, chi core dish 3, casing cover 5, handle set 6 and handle 9, described buffering spring sheet 2 is arranged on shell 1, shell 1 and casing cover 5 fasten, chi core dish 3 between shell 1 and casing cover 5 and chi core dish 3 be connected with buffering spring sheet 2, chi core dish 3 is provided with chi core dish gear 31, it is provided with cover plate 4 between chi core dish 3 and casing cover 5, the outside of casing cover 5 is provided with handle set 6, handle set 6 is provided with handle set gear 61, it is outside that one end of handle 9 is arranged on casing cover 5 by handle cap 7, the other end of handle 9 is arranged on handle set 6, handle set gear 61 and chi core dish gear 31 are meshed.Handle 9 is arranged on handle set 6 by straight pin 10.Handle 9 and handle cap 7 adopt rivet 8 to lock.
Operation principle of the present utility model is: during use, only need to be shaken gently for handle 9, and handle 9 drives handle set gear 61 to rotate, and handle set gear 61 drives chi core dish gear 31 to rotate thus driving chi core dish 3 to rotate, and reaches the effect of speed change.This apparatus structure is simple, reasonable in design, simple to operation, only needing turning handle 9, handle 9 to drive handle set gear 61 to rotate, handle set gear 61 drives chi core dish gear 31 to rotate thus driving chi core dish 3 to rotate, folding and unfolding tape can be realized, frictional force is little, laborsaving during folding and unfolding tape, and result of use is good.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible to make a variety of changes under the premise without departing from this patent objective.
