Description
Technical field
The utility model relates to a kind of weight adjusting device of cue.
Technical background
The weight adjusting device that is disposed on the present known cue is arranged on the handbar of the cue body of rod, generally is made of a plurality of screws, and a tapped long screw is set in handle.Therefore when mounted, a plurality of screws need be screwed in the screw successively, make it into concentricity axle and arrange, and when dismounting, need screw out each screw successively and can take out all screws, therefore use very inconvenient.
The utility model content
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of weight adjusting device of cue simple in structure, easy to use.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: a kind of weight adjusting device of cue, screw by three concentricity axle assemblings constitutes, they are respectively outside nut, internal thread and middle screw, described outside nut and middle screw all are hollow tubular, have internal thread on the inner surface of described outside nut, have external screw thread on the outer surface of described internal thread, have external screw thread in the middle of described on the outer surface of screw with the internal thread coupling of outside nut, its inner surface is provided with the internal thread with the external screw thread of internal thread coupling, also be spirally connected with it in the screw in the middle of described internal thread penetrates, described middle screw penetrates in the outside nut and is spirally connected with it.
External screw thread on the described internal thread can be arranged on the top of the outer surface of internal thread, and the bottom of the outer surface of described internal thread is a smooth surface.
Internal thread in the middle of described on the screw can be arranged at the top of its inner surface, and the bottom of its inner surface is a smooth surface.
The internal thread of described internal thread can be arranged at the top of its inner surface, and the bottom of its inner surface is a smooth surface.
Can be provided with cross recess on the top end face of described internal thread.
Can be provided with the multiple tracks flat recess on the top end face of described outside nut and middle screw.
Described internal thread can be solid construction.
Can be provided with external screw thread on the outer surface of described outside nut.
In technique scheme, the utility model has been owing to adopted the screws of three concentricity axle assemblings to constitute weight adjusting device, thus can freely select need taking-up or install one of them, two or three screws; In addition,, so only need go up several circles during dismounting and just can tighten because that the internal thread of the internal thread of the external screw thread of internal thread, middle screw and outside nut all is provided with is shorter, very rapid.Therefore relatively prior art, the utlity model has simple in structure, implement easily, dismounting fast, characteristics such as convenient.

Accompanying drawing 2 is that the A-A of Fig. 1 is to cutaway view;
Accompanying drawing 3 is that the B-B of Fig. 1 is to cutaway view;
Accompanying drawing 4 is the main TV structure schematic diagram of another kind of embodiment of the present utility model.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is described in further detail.
Embodiment 1:
With reference to Figure of description 1, a kind of weight adjusting device of cue, the screw of being assembled by three concentricity axles constitutes, and they are respectively outside nut 3, internal thread 1 and middle screw 2.
Described internal thread 1 is the cylindrical of solid construction, and its top end face is provided with the cross recess 10 that is used to screw screw, and the top of the outer surface of its side is provided with an end external screw thread 11.The length of described external screw thread 11 and the number of turns can be provided with less.The bottom of the outer surface of its side is the smooth face of cylinder.
With reference to figure 1,2, described middle screw 2 is hollow tubular.Its top end face is provided with the flat recess 20 that multiple tracks is used to screw screw, and its outer surface is provided with external screw thread 21, and the top of its inner surface is provided with the internal thread 22 with external screw thread 11 coupling of internal thread 1, and the bottom of its inner surface is the smooth face of cylinder.
With reference to figure 1,3, described outside nut 3 is hollow tubular.Its top end face is provided with the flat recess 30 that multiple tracks is used to screw screw.Have external screw thread 31 on its outer surface, its inner surface is provided with the internal thread 32 that the external screw thread 21 with middle screw 2 is complementary.The length of described internal thread 32 and the number of turns can be provided with less, thereby the bottom of the inner surface of outside nut 3 is the smooth face of cylinder.
During use, if load onto this weight adjusting device, then owing to the internal thread of the external screw thread 31 that can make outside nut 3 with the handbar setting of cue is complementary, thereby earlier outside nut 3 is screwed to cue, by the mode that is spirally connected middle screw 2 is screwed in the outside nut 3 successively then, again internal thread 1 is screwed in the middle screw 2.Perhaps also can be earlier internal thread 1 and middle screw 2 be packed in the outside nut 3 successively, property is screwed into this weight adjusting device in the body of rod of cue again.
If dismantle this weight adjusting device, its operating procedure is opposite with installation.Need can select the several screws of disposable dismounting as required.In addition, because the external screw thread 11 on the internal thread 1, and the external screw thread 21 equal quantity of middle screw 2 are less, therefore only need screw the just energy dismounting of several circles, can reach the purpose of dismounting.
Embodiment 2:
Difference from Example 1 is: the length of the inside and outside lip-deep screw thread of screw 2, outside nut 3 all equates with the height on its inside and outside surface in the middle of described.And, set up a rubber nut 4 on the top of cue, thereby 3 screws can be screwed in the top of cue in use, seal the screw on top again with rubber nut 4, keep the overall aesthetics of cue.Therefore compare with embodiment 1, though present embodiment no longer has the characteristics of fast assembling-disassembling, its optionally dismounting still can bring bigger ease of use.
In addition, in the practical application, can also increase or reduce the quantity of screw as required, also can increase or reduce the length and the number of turns of screw thread.Therefore, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
