Description

Filling type dumbbell

Technical field

The utility model relates to a kind of dumbbell, the filling type dumbbell that particularly a kind of its weight can be allocated arbitrarily.

Background technology

General traditional dumbbell structure, it is the balancing weight of each screw lock one metal material at the two ends of a holding rod, wherein, the two ends of this holding rod are provided with thread segment, and balancing weight therein axle to being provided with internal thread segment too, fixing for cooperating thread segment with holding rod to revolve lock, its shortcoming is, except holding rod, balancing weight all need be done repeatedly procedure of processing (polishing, attack the system screw thread), and need to make the counterweight mould of many group Different Weight, so that the dumbbell pattern of various Different Weight specifications to be provided; So, the producer is reflected on the price, and the consumer has no way of selecting at all.Moreover aforesaid its weight specification of traditional dumbbell all belongs to fixed, when consumer wants is done the weight of rank property increase dumbbell into, also can only constantly buy the dumbbell of Different Weight specification; For this reason, there is the dealer to develop the multiple structure of adjusting dumbbell weight, checking and approving case as the Taiwan patent announces No. 363435, be a kind of adjustable dumbbell structure, this dumbbell is made up of the lever that two hollow holding parts and one are connected between the two hollow holding parts, it is characterized in that: shank part is a hollow columnar, and this shank part one is connected in holding part in two, communicates and the two hollow holding parts and the inner space of shank part are become; Two hollow holding parts are identical shaped, comprise its outer surface, be equipped with extendable temple members portion respectively, each extendable temple members portion is its flexible amplitude of free adjustment according to need, the content space of two hollow holding parts is increased or dwindle, be positioned at wherein that a hollow holding part end face is provided with water injection hole, this water injection hole can cover into sealing leak-stopping shape by a side cover.Though can being filled into water by its water injection hole place, said structure links all-in-one-piece two hollow holding part and shank parts, reach the purpose that arbitrarily to adjust dumbbell weight, but its shortcoming is: be two hollow holding parts that hollow communicates and shank part after injecting water or inserting counterweight sand, if all spaces are not filled up, then when using dumbbell, be flat act operation or all ccontaining the rocking of vertical act operation because of water, the center equalization point nowhere the dumbbell milli is fixed, easily cause in the use not smooth, and the continuous conversion of position of centre of gravity, cause that the hand tendon is injured easilier.

The utility model content

The purpose of this utility model provides a kind of counterweight and can adjust arbitrarily, and the filling type dumbbell that position of centre of gravity can not change.The utility model includes an a pair of accommodating body and a lever, wherein, this accommodating body is with the soft materials integrated injection molding, and axle is to being provided with an axis hole therein, and the two ends of lever are located in the axis hole of two accommodating bodies and locate, book office at accommodating body is provided with a filler opening, can provide counterweight sand to insert in the accommodating body, because two accommodating bodies are not mutual perforations, so the counterweight sand in it can arbitrarily not flow mutually by this filler opening place, guarantee the stable of center of gravity, can not damage the hand tendon.

In addition, accommodating body can be made into and is an ellipse, and its Y forms a microscler through hole, is provided with the less perforation in aperture at X, and this perforation is connected with microscler through hole, and is provided with a filler opening at the side face book office of accommodating body; Lever is located in perforation place location.

The specific embodiment

See also Fig. 1, shown in Figure 2, be first embodiment of the present utility model, it includes two accommodating bodies 10 and a lever 20, wherein, accommodating body 10 is with the soft materials integrated injection molding, be formed with hollow bulb 11 in it, this accommodating body 10 therein axle to being provided with axis hole 12, the two ends of lever 20 are arranged in location in this two axis hole 12, and be formed with filler opening 13 at two accommodating bodies, 10 side face book offices, this filler opening 13 is tapered, its point is through the hollow bulb 11 of accommodating body 10, the pore of above-mentioned point almost is complete closure state, and it is to utilize soft materials, so have plasticity, can point be strutted by the insertion of filler opening 13 places when loading the employed conduit of the husky A of counterweight, after treating that packing job is finished the extraction conduit, this point can return again and be moulded former closure state, is outwards spilt by filler opening 13 places to prevent the husky A of counterweight again; The slightly larger in diameter of lever 20 in addition, can respectively add concave, convex ring section or embossing section at two ends of lever 20 in the diameter of the axis hole 12 of accommodating body 10, lever 20 is embedded at axis hole 12 places of accommodating body 10 closely combine to reach.

The dumbbell of said structure after two accommodating bodies 10 are all inserted the husky A of counterweight, can be nested with respectively at the two ends of lever 20 by its axis hole 12, finishes the assembling of dumbbell; Wherein, the accommodating body made from elastomeric material 10 has preferable ductility, and therefore, having bigger extending space can import or derive for the husky A of counterweight, to do the adjustment of weight.In addition, this accommodating body 10 has than better elastic, pounds foot even if drop because of carelessness, can be not injured yet, and play can be not dangerous yet even child takes away.

See also Fig. 3, shown in Figure 4, be second embodiment of the present utility model, accommodating body 100 is an ellipse, and its Y forms a microscler through hole 101 and communicates, and the side face book office at accommodating body 100 is provided with a filler opening 103, is imported by this filler opening 103 for the husky A of counterweight; Lever 20 directly is located in location, perforation 102 places, can grip lever 20 operation dumbbells by the microscler through hole of the Y of accommodating body 100 101 places; Wherein, the position, microscler through hole 101 place that oval-shaped soft accommodating body 100 also may be implemented in its Y formation is connected to form a pipe box 104 at X, these pipe box 104 1 ends run through accommodating body 100 outer rims, running through end for lever 20 by pipe box 104 penetrates, so lever 20 promptly need not sheathed any sheath for holding section again, also can increase the accommodation space of accommodating body 100, as shown in Figure 5.
