Description

The exercycle dragulator

The utility model relates to a kind of exercycle dragulator.

See also shown in Figure 1, general dragulator 10 mainly convexes with a center pillar 111 in a base 11 central authorities, these center pillar 111 central authorities have provided a screw 112, one rotating shaft 12 can overlap pivot and rotate on center pillar 111, its lower end is provided with a runner 121 can establish a resistance trolley 13 for connecing, this resistance trolley 13 can be passed to the outside by base 11 side openings 113, and rotating shaft 12 tops are provided with side's bolt pipe 122.One body 14 is fixed on the base 11, its end face is provided with two apertures 141 relatively, but ammunition feed is established a steel ball 142 in the aperture 141, one knob, 15 central authorities have provided a keyhole 151, can overlap pivot on rotating shaft 12 side's bolt pipes 122, but make knob 15 interlock rotating shafts 12 turn around resistance trolley 13, knob 15 bottom sides have installed a segmented disc 16, and this segmented disc 16 has several locating holes 161 and can pull for steel ball 142 bullets.Knob 15 can reach the segmentation corrective action whereby, these knob 15 end faces are concaved with a dish hole 152 can take over a business part 17 for being nested with one, this is taken over a business part 17 lower ends and is provided with a screw rod 171 and can be screwed with center pillar 111 screws 112, taking over a business part 17 can keep and maintain static, take over a business the part 17 end faces digital label 172 that has been sticked, make knob 15 when switching, its index 153 rotatable pointing on the corresponding section numeral, so this knob 15 can show present resistance section by forward.

Above-mentioned dragulator has the resistance trimming function really, but still desirable not to the utmost on demonstration and result of use.General dragulator is sticked digital label 172 in order to indication resistance hop count on knob 15, but this digital label 172 is owing to be the printing printed words, visually be subjected to light, font size and user's visual acuity affected easily, it is inaccurate to cause the user to judge.Therefore the resistance hop count that how to allow the user come into plain view to distinguish demonstration is the target that the designer lays siege to always.In addition, this knob 15 compresses in order to spacing on rotating shaft 12 by taking over a business part 17, and knob 15 uses need have good rotation smooth degree, but knob 15 is subjected to compressing of part 17, often causes knob 15 switchings to have some setbacks.

The utility model purpose is to provide the clear and knob of a kind of demonstration resistance hop count exercycle dragulator smoothly.

The utility model provides a kind of exercycle dragulator, comprise a base, be connected with a body on this base, central interior is stretched and is provided with a center pillar, this center pillar can be established a rotating shaft for axle, the rotating shaft lower end is equipped with a resistance trolley, and upper end cover pivot has a knob, it is characterized in that: this base is socketed with a guiding socle in bottom center; This rotating shaft is provided with side's bolt pipe in the top, this side's bolt pipe proximal portion is concaved with an annular groove, and formation two minor faces are established in the relative two jiaos of end-grain cutting in square bolt pipe top; This knob, its end face one side edge is embedded with an index, and centre also is concaved with a dish hole; One banking stop for having the pad of thickness, is pressed against the dish hole surface, offers a slotted hole in inside, and this slotted hole supplier bolt pipe minor face is inserted in and locks and set this knob of position; One takes over a business part, it comprises an inner disc, an outer dish and a digital rings, this inner disc is fixed in the knob wheel hole, its corresponding index location is provided with a protuberance of tool color, should be fixed in the center pillar upper end by outer valve snail, it offers an arc groove and is inserted in mobilely for protuberance, and this digital rings cover cap coils outside, and corresponding arc groove position is provided with the printing opacity numeral.

From the above, the utility model can reach as after effect:

(1). display effect is clear

The protuberance that the setting of the utility model inner disc has color, protuberance can be done turn with knob, and has the printing opacity numeral on the digital rings, when making protuberance arrive each digit position, can allow this numeral present anti-white the demonstration, so as to showing the resistance hop count of present dragulator, the user can distinguish clearly easily quite that display effect is very good.

(2). knob is smooth and easy

The utility model knob utilizes banking stop to support only locking on rotating shaft, wholely take over a business part and do not need knob is compressed action, the utility model is taken over a business part and is directly locked on center pillar, can not compress and cause retardance the knob wheel hole, so the utility model knob can be done switching glidingly, rotates quite smooth and easy convenience.

(3). install aesthetic in appearance

The utility model is embedded in the car pipe with base, and its resistance trolley can directly enter the car pipe and can not expose, and the whole erection outward appearance is quite simple and clear clean and tidy, can promote the aesthetic property of product.
