Description
Technical field
The utility model relates to a kind of sports apparatus, particularly relates to a kind of safe fast-assembling dumbbell.
Background technology
Existing dumbbell constitutes with the counterweight that is threaded onto the lever two ends by irritating lead and the screwed lever in two ends usually.This exists two disadvantages:
1. because in the process that dumbbell is lifted up and down; people's hand can apply certain moment of torsion to dumbbell; because the inertia of dumbbell integral body and directly be subjected to the lever inertia of torsion to exist bigger difference, so through regular meeting counterweight was rotated counterclockwise and broke away from lever under effect of inertia situation appears.In case counterweight breaks away from lever, has and pounds the situation of hurting sb.'s feelings or smashing property, for dumbbell exercise, this is a potential safety hazard.
2. because the installation of scale pan and unload and all need scale pan rotate a lot of the commentaries on classics around lever, operate very time-consuming, inconvenience extremely like this.
The utility model content
The utility model provides a kind of safe fast-assembling dumbbell with counterweight locking mechanism for solving the deficiencies in the prior art.
The scheme that solves the utility model technical problem is: safe fast-assembling dumbbell is made of push rod, spring, sleeve, scale pan, microsprings, securing rod, anti-sliding sleeve, bar hole, lever, fixed via and retainer ring.Wherein, anti-sliding sleeve is that lateral surface is the rubber sleeve of arc, and anti-skidding condom is on the groove at lever middle part.Lever is cylindrical, the two ends of lever be with the lever concentric and with the as a whole sleeve of lever.In the distance with the termination, outer end of sleeve is that 1/2 place of lever length has a retainer ring, retainer ring be with lever be holistic torus.The outer end of sleeve opens wide, and many group fixed vias are arranged on the side of sleeve, and each group fixed via is made up of three fixed vias that are mutually 120 ° of circle distribution, and vertical distance of shaft centers of every two adjacent groups fixed via is than the long 1mm of scale pan thickness.The lateral surface of each retainer ring and the distance in the axle center of one group of nearest fixed via with it are half of scale pan thickness.Push rod is made up of the round platform that differs in size at columniform bar portion and two ends.The bottom surface diameter of the round platform of the bigger end of push rod equates with the overall diameter of sleeve, forms a ring-shaped step between this round platform and the push rod portion, and the round platform bottom surface diameter of the end that push rod is less is the bar portion diameter of push rod.The less end of push rod is in the sleeve, and push rod and sleeve are in active relationship.Spring housing is in the bar portion of push rod, and the described ring-shaped step of an end of spring and the bigger end of push rod welds, the external port place welding of the other end of spring and sleeve.Scale pan is the oblate cylinder that a plurality of diameters do not wait, there is manhole at the middle part and thickness is identical.Three equal and opposite in directions are arranged on the medial surface of the manhole of each scale pan and be mutually the bar hole of 120 ° of circle distribution.Securing rod is that an end is the cylinder on plane for the hemisphere face other end, the end that securing rod has a plane is in the bar hole and with the bar hole and is in active relationship, microsprings is in the bar hole, one end of microsprings and the welding of the bottom in bar hole, the other end of microsprings and securing rod have the end welding on plane.Scale pan is enclosed within on the sleeve, and each securing rod has a hemispherical end and is inserted in the fixed via on the described cartridges sides and with fixed via and is in active relationship.
In the time of need unloading scale pan, only need push rod is pushed away in sleeve, under the promotion on the truncated cone-shaped inclined-plane of push rod termination, securing rod can be pushed in the withdrawal bar hole, can take off scale pan easily this moment from sleeve. in the time of scale pan need being installed, the outer end of scale pan being aimed at push rod inwardly pushes away, under the effect on inclined-plane, push rod outer end in the securing rod withdrawal bar hole, when scale pan is moved on the fixed via position, unclamp push rod, and rotate scale pan and align with fixed via, at this moment until the bar hole, securing rod inserts in the fixed via under the promotion of microsprings, with the position relation locking of scale pan and sleeve.
Adopt such scheme, can reach following effect:
1. use the utility model is installed and is unloaded scale pan and compare very efficient and convenient with traditional helicitic texture.
2. because scale pan is not to rely on screw thread to be fixed on the lever, therefore in the process of lifting or put down dumbbell, no matter produce great moment of torsion, scale pan all can't slide from lever.So just eliminated the potential safety hazard that causes because of the scale pan landing in the dumbbell exercise.
3. because securing rod is mutually 120 ° of circle distribution, make the latching force equilibrium between scale pan and the sleeve, locking effect is better.
