DETAILED DESCRIPTION OF THE INVENTION The outer shape of a dumbbell adjusting device is shown in FIG. The dumbbell adjustment device consists of a bell's frame (Fig. 2) and a bell set (Fig. 4). In Fig. 2, the function of the casing 1 is to support or park the bell and safety protection. Gear 2 is coupled to 6 of Figure 5. Figure 3 is a view showing the internal structure of the casing after the casing is removed. Rotate the knob 4 so that its arrow points to the selected weight scale. The sprocket fixed on the twisting shaft will drive the chain 3 to move, so that the gear 2 rotates and drives the gear 6 (see Figure 5) to rotate. The square hole in 6 and the square ring on the cam sleeve 7 are coupled (see Fig. 5-1) to rotate the cam sleeve 7, and the push rod 9 mounted in the support body 8 is controlled to move up and down by the concave and convex position on the cam sleeve. The slider 10 is kept in contact with the inclined surface of the upper portion of the push rod 9 by the action of the spring 11, so that the slider 10 is in a state of being extended or retracted with respect to the support body 8. When the slider 10 is in the extended state (see Fig. 5-3), it will protrude into the hook groove 13 of the bell piece 12, at which time the bell can be lifted with the grip 5. When the slider 10 is in the retracted state (see Fig. 5-2), the tab at the corresponding position of the slider will not be able to move with the grip and stay in the corresponding position of the casing 1. Figure 6 shows the mouth. In order to facilitate the operation, the mechanism adopts a symmetrically arranged forward and reverse mechanism (see the function of interchangeable left and right. At the same time, in order to reduce the gap of the transmission chain, the mechanism uses the eccentric tensioning mechanism (see Figure 3). When the operation is reversed, the mechanism can be accurately positioned. In addition, the mechanism uses a locking mechanism (see Figure 7) to prevent the operator from turning the knob and causing an indication error while lifting the bell set. When the set of the bell is not lifted, the part 16 fixed on the grip presses the protrusion 14 which can slide up and down to disengage the slot on the gear 2, so that the gear 2 can be freely rotated to select different weights; After the grip and the bell set are lifted, the projection 14 is no longer pressed, and protrudes outwardly under the action of the spring 15, and snaps into the slot of the gear 2, so that the adjustment knob cannot be rotated to ensure accurate indication. . In order to allow the operator to have a clear perception when the selection is in place, the mechanism has designed a positioning device in addition to the arrow (see Figure 8). The knob 4 has a cylindrical hole for accommodating the spring 16 and the steel ball 17 for axial movement, and the positioning seat 18 having the positioning cone is fixed in the hexagonal hole of the casing 1. When the rotation is in place, the mechanism emits a slight The "beep" sound, and when the outside world unexpectedly vibrates, the twist can still accurately stay in the selected gear without swinging left and right. In order to allow the bells that are not selected and stay on the casing 1 to stably stay in the corresponding seats, the mechanism has a flap 19 designed beside the bell seat of the casing. The flap 19 ensures that the bell does not fall over and that the spacing between the bells is ensured (see Figure 9). In order to make the bells staying on the casing not affect the reset of the bell group, the mechanism has a bevel 20 on the upper part of the bell, so that the operator can return the unselected bell group even if the position is not accurately positioned. It can also be placed back in place (see Figure 10). In order to simplify the structure of the bell group and make it more convenient to manufacture and use, the mechanism adopts a two-chain reversing device. It is also possible to use a device in which the two chains rotate in the same direction, but this would make the structure more complicated and inconvenience to manufacture and use. If the mechanism removes any pair of the left and right pairs of gears that control the two sets of bells, it can become a mechanism that only adjusts one rotation and can control the change of both ends of the single set of bells. If the axial and radial dimensions are appropriately increased, it can become a control mechanism for adjusting the weight of both sides of the weightlifting barbell. The transmission mechanism inside the casing of the mechanism can also be driven by multi-gear engagement (see Fig. 11), the worm drive or the timing belt is used instead of the chain transmission, and the gear chain transmission is used instead of the roller chain transmission. The adjustment knob in this mechanism can also be made into a button form. The button controls the angle required for the micromotor 22 to rotate through the circuit control board 23, and rotates the central shaft 21 through the transmission chain, thereby achieving the purpose of selecting different weights. The button can be placed on the top or side of the cover. The control panel can be mounted in the space of the enclosure or base (see Figure 12). The mechanism can also use electromagnetic control to select the weight, and the battery 24 can be mounted in the center of the grip (see Figure 13). When the electromagnet 26 is energized, the top block 27 is moved downward against the force of the spring 28, and the slider 10 that hooks the bell piece under the action of the spring 11 is in a retracted state, and the bell in the corresponding position will stay in place. It cannot be lifted; when the electromagnet 26 loses power, the top block 27 overcomes the action of the spring 11 under the force of the spring 28. The force causes the slider 10 to be in an extended state, and if the grip is lifted, the corresponding bell can be lifted. The circuit board 25 can be mounted on either side of the handle as shown in the figures, and the control buttons can be mounted on the top or side of the housing (as shown in the upper view of Figure 12). The control panel can be mounted in the interior of the enclosure. The shape of the shell of the body can be made into a variety of shapes, such as cubes, cuboids, multi-slots, etc. Different notches and depressions can be dug in the body, and each plane can be replaced by a different surface. Each shuttle angle can be inverted into different rounded corners or corners. The shape of the bell in this organization can also be made into a variety of different shapes, and the outer circle is cut into polygons, or polygons. Modifications and variations of the present invention will be apparent to those skilled in the <RTIgt; Such modifications and variations are intended to be included within the scope of the present invention as defined by the appended claims.
