The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The schematic diagram of the utility model cylindrical cam type counterweight adjusting device such as Fig. 1-shown in Figure 6, comprise taper knob 10, two bearing units, counterweight adjusting mechanism and balancing weights 20, the schematic diagram of described balancing weight 20 as shown in Figure 6, comprise disk shape body 25, described body 25 centers are provided with centre bore 24, body is provided with open slot 23, and described open slot 23 radially passes centre bore 24 and to a side opening.Described counterweight adjusting mechanism comprises spiral cover 15, regulating spring 14, steel ball 13, location-plate 12, cylindrical cam 11, two guide pin bushings 9 and two guide pillars 3.Described bearing unit comprises outer end cap 3, inner end cap 6, upper support piece 4 and lower support piece 1, described upper support piece and lower support piece outside are respectively arranged with balancing weight upper shed groove 23 corresponding balancing weights and lay groove 18, adjacent balancing weight is laid between the groove and is separated by boss 22, and described upper support piece 4 inside are provided with guide pillar walking passage 21.In the described taper knob 10 cylindrical cam 11 is installed, two guide pin bushings 9 are installed between described cylindrical cam 11 and the taper knob 10, each guide pin bushing 9 is connected with guide pillar 5 in placing upper support piece upper guide post walking passage 21, have on the described cylindrical cam to make two profile grooves that the guide pin bushing direction of motion is opposite, insert in the profile groove of cylindrical cam guide pillar 5 lower ends.Described outer end cap 3 is fixedlyed connected with the outer end of cylindrical cam 11, and described upper support piece 4 is fixedlyed connected with outer end cap 3 by screw 2 respectively with lower support piece 1 one ends, and the other end of described upper support piece and lower support piece is connected by screw 7 with inner end cap 6 respectively.One end of described cylindrical cam 11 is fixedlyed connected by screw 16 with spiral cover 15, in the described spiral cover 15 regulating spring 14 is installed, between the outer end cap of a described spiral cover 15 and a corresponding side location-plate 12 is installed, described location-plate is provided with a plurality of locating holes, is equipped with between described regulating spring 14 and the location-plate 12 and the corresponding steel ball 13 of locating hole.Steel ball enters in the different locating holes in the process of spiral cover rotation, and corresponding guide pin bushing is mentioned different weight blocks, and realizes the location by steel ball.The diameter of described guide pin bushing is less than the diameter of the balancing weight centre bore width greater than open slot, the diameter of described cylindrical cam and guide pillar is less than the open slot width on the weight block, like this, ensure that guide pin bushing can pass centre bore but balancing weight is mentioned in the restriction that is subjected to open slot, cylindrical cam and guide pillar can pass centre bore and open slot and not influence mentioning and discharging of balancing weight.
Be respectively arranged with corresponding guide pillar installing hole 19 with guide pillar initial position corresponding upper support piece top and inner end cap.
In order clearly to find out the weight of the weight block of being mentioned, described spiral cover is provided with counterweight numerical value, and the outer end cap of a corresponding side with spiral cover is provided with the counterweight mark.
In each inner end cap outside deckboard 8 is installed.
More firm in order to connect, described inner end cap is placed in the groove of taper knob end.
Rotate spiral cover 15, driving cylindrical cam 11 rotates, cylindrical cam 11 drives two guide pillars, thereby drive the guide pin bushing 10 that is connected with corresponding guide pillar, the diameter of guide pillar is less than the open slot on the weight block, the effect of guide pillar is to prevent that guide pin bushing from rotating with cylindrical cam, and guide pillar is limited in interior the moving of guide pillar walking passage of upper support piece.Be subjected to the constraint of guide pillar, guide pin bushing can only do reciprocating linear motion in the endoporus of taper knob 9 vertically, and two guide pin bushings 10 are when stretch out from inside to outside the both sides of handle 9, and the external cylindrical surface of guide pin bushing passes from the centre bore of weight block.When upwards mentioning handle, weight block hangs on the external cylindrical surface of guide pin bushing and is raised, and Xuan Ding weight block is not retained in the original position on the base, and the length of guide pin bushing equals the thickness sum of each weight block and boss.
The spiral cover that is positioned at cylindrical cam one end can rotate by the relative weight piece, rotates spiral cover and can make guide pin bushing be in different telescopic locations.When the counterweight mark on the counterweight weight numerical value aligning outer end cap 3 that marks on the spiral cover, mention handle 9, the weight block that guide pin bushing passes is draped and mentions; During backward rotation spiral cover 15, the weight block that breaks away from guide pin bushing can discharge automatically.
Cylindrical cam type counterweight adjusting device of the present utility model can realize that the weight that can be used for dumbbell is regulated to the mentioning and discharge of suspension type weight.Adopt a kind of Stability Analysis of Structures, weight adjusting device that controllability is strong, release quick more convenient, safe and reliable dumbbell kind.The utility model is started with from the theory of engagement and machine driving aspect, analyze at aspects such as the controllability of body-building dumbbell and security performances, new design has been proposed, for society provide a kind of safe and efficient easily, be fit to the weight adjusting device that weight block grasps and discharges.
