Abstract

The utility model relates to the technical field of sport facilities, in particular to a pool cue. The pool cue is composed of a plurality of pool cue sections which are jointed, the pool cue sections are penetrated and pulled straightly by a flexible pull string, and in two jointed pool cue sections, the joint end of a first pool cue section is provided with a socket, the joint end of a second pool cue section is arranged into a contraction step shaft, and the step shaft is right inserted in the socket inlaid in the first pool cue section. The pool cue is penetrated and pulled straight by a flexible string, which has convenient and rapid assembly and disassembly, does not need to be wrenched with screws or processed with screw threads, and has relatively low cost. The step shaft is inserted in the socket, and an O-shaped ring is arranged at the joint portion, which has good tightness, is not easy to loosen and ensures the pool cue to be straight.

Description

Collapsible billiard stick

Technical field:

The utility model relates to technical field of sports apparatus, refers in particular to a kind of billiard stick.

Background technology:

Known, billiard stick is the stock body that an end is little, an end is big, and integral type is arranged, and segmented is also arranged, and integral type billiard stick length is longer, is difficult for receiving and keeping and carrying; And segmented billiard stick detachable multistage body of rod when not using, thereby dwindle length, be beneficial to and receive and keep and carry.But in the prior art, the segmented billiard stick is to adopt the mode be threaded to make up, and dismounting is comparatively loaded down with trivial details, and connects defective tightness, is prone to looseningly, and it is poor to cause making up back billiard stick linearity, and influence is used.

Summary of the invention:

The purpose of this utility model is to provide a kind of collapsible billiard stick of easy disassembly.

Another purpose of the utility model is to provide a kind of simple in structure, the collapsible billiard stick that processing and fabricating is easy.

The another purpose of the utility model is to provide a kind of connection stable, the collapsible billiard stick that gained billiard stick linearity is good.

For achieving the above object, the utility model adopts following technical scheme to realize:

Collapsible billiard stick, this billiard stick is connected mutually by the several sections bodies of rod and constitutes, run through by elastic drag rope between the body of rod and pull and support linking, and in two sections bodies of rod that are connected mutually, the cohesive end of first body of rod leaves socket, and the cohesive end of second body of rod is the step axle of bringing together, and this step axle inserts just and is embedded in the socket of first body of rod.

It is to be combined with O shape ring on the step axle periphery of second body of rod that technique scheme is further improved.

Pull and support in the elastic drag rope that is connected mutually in the body of rod, its both ends are respectively to be connected to horizontal bayonet lock, and two bayonet locks are connected to the step of first body of rod and second body of rod inside respectively; The position that bayonet lock system connects elastic drag rope is an arch, the direction that arch pulls and supports towards elastic drag rope.

For cooperating the arch of bayonet lock, be provided with the ring pad in the step shaft end endoporus place of second body of rod, the ring pad is supported the arch of the bayonet lock of first body of rod inside just during assembling.

Billiard stick described in the utility model can be fiber rod, wooden stick, plastic cement rod or metallic rod.

Be compared with the prior art, the collapsible billiard stick that the utility model provides has following beneficial effect:

1, run through by elastic drag rope and pull and support linking, easy accessibility, quick need not to twist screw thread, does not also need machining screw, and cost of manufacture reduces relatively.

2, be connected stable, embed socket by the step axle, and be provided with O shape ring at junction, compactness is good, and is difficult loosening, guarantees the linearity of billiard stick.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model partial structurtes schematic diagrames;

Accompanying drawing 3 is the folding schematic diagram of the utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

See that accompanying

drawing

1,2 is depicted as the utility model one embodiment, this billiard stick is made of 1, the 2 mutual linkings of two sections bodies of rod, 1,2 of the bodies of rod are run through by elastic drag rope 3 and pull and support linking, and in two sections bodies of rod, the cohesive end of first body of rod 1 leaves socket 11, and the cohesive end of second body of rod 2 is the step axle of bringing together 21, and this step axle 21 inserts just and is embedded in the socket 11 of first body of rod 1.The effect that step axle 21 has the location and strengthens being connected is connected two sections bodies of rod and axially is connected better.

Elastic drag rope 3 runs through and pulls and supports linking, and easy accessibility, quick only need draw back two sections bodies of

rod

1,2 relatively, can realize that cohesive end separates and folding billiard stick, thereby shorten billiard stick length, conveniently receives and keeps and carries.When needing to be connected, relieving is folding, and the cohesive end of two sections bodies of

rod

1,2 is docked mutually, step axle 21 inserts just and is embedded in the socket 11 of first body of rod 1, and under the effect of elastic drag rope 3, two sections bodies of

rod

1,2 is combined closely in the axial direction, form a stock, i.e. billiard stick.

In the present embodiment, on step axle 21 peripheries of second body of rod 2, be combined with two O shape rings 4, utilize O shape ring 4, can well connect airtight the socket 11 of first body of rod 1, prevent to become flexible, improve the linearity that is connected.O shape ring 4 is a plastic cement material, can be provided with one or morely on step axle 21, makes connection tightr.

Pull and support in the elastic drag rope 3 that is connected mutually in the body of rod, its both ends are respectively to be connected to the

step

12 and 22 that horizontal bayonet lock 5, two bayonet locks 5 are connected to first body of rod 1 and second body of rod, 2 inside respectively.Bayonet lock 5 is that the position that connects elastic drag rope 3 is an arch 51, the direction that arch 51 pulls and supports towards elastic drag rope 3, and arch 51 can be strengthened the stability of elastic drag rope 3, and it is pulled and supported at axial straight line all the time, avoids taking place oblique line and pulls and supports two sections bodies of rod.The arch 51 that cooperates bayonet lock 5 is provided with ring pad 6 in the endoporus place, step axle 21 end of second body of rod 2, ring pad 6 is supported the arch 51 of the bayonet lock 5 of first body of rod, 1 inside just during assembling, can further strengthen like this being connected, and improves to connect steadiness.

Shown in the accompanying drawing 3, draw back the body of

rod

1,2 relatively, promptly collapsible, elastic drag rope 3 provides folding flexibility, adds C shape latch closure 7 between the folding relatively body of

rod

1,2, and C shape latch closure 7 is the clamping body of

rod

1,2 respectively, make the body of

rod

1,2 relative fixed, promptly obtain the state of the folding harvesting of billiard stick.

Billiard stick described in the utility model can be fiber rod, wooden stick, plastic cement rod or metallic rod, satisfies actual needs.
