Description

A kind of novel contractile bat

Technical field

The utility model relates to field of athletic equipment, particularly relates to a kind of novel contractile bat.

Background technology

Baseball is the ball game project that a kind of antagonism is very strong, and along with baseball at home universal, increasing people likes enjoying the enjoyment that this motion brings.Existing bat, primarily of the section of strike, the section of shaking hands, chock plug composition, hit between section and the section of shaking hands and there is arc-shaped transition, therefore, relative to other sports equipment, bat entire length is long, it is not very desirable for carrying, and therefore, the utility model is in prior art, propose a kind of novel contractile bat, object is to solve bat problem easy to carry.

Summary of the invention

For achieving the above object, the scheme that the utility model solves is: a kind of novel contractile bat, by handle ring, front end, rear end, chock plug forms, and its front end is by the first straightway, segmental arc, second straightway composition, the first straightway of front end and handle ring are welded to connect, and rear end is by rear end external screw thread, rear end straightway, rear end internal thread composition, the rear end internal thread of rear end and chock plug are threaded, it is characterized in that: connected by link between front-end and back-end, described front end, the head of its second straightway also has slide head, its slide head is provided with two sliding trays, sliding tray is provided with sliding ring, described link, comprises link segmental arc, link straightway, and in the inside of link, also there is annular I groove, annular II groove, annular I groove, arrange screw thread in annular II groove, screw thread and the rear end external screw thread of annular II groove of link are threaded connection fixing, and the slide head of front end, by sliding ring, can move to the afterbody of rear end from link.

Further, described front end, its second straightway has nose threads, and the screw thread of annular I groove of link can be threaded with nose threads.

Further, the external diameter of described front end slide head part is greater than the external diameter of the second straight length portion of front end, makes the junction between slide head and the second straightway form an annular table terrace fallen.

Further, described link, the diameter of its annular II groove is larger than annular I groove, make the junction between annular I groove and annular II groove have an annular table terrace, thus annular II groove of the rear end external screw thread of rear end and link form an inwall without step surface in inside after being threaded.

Preferably, described sliding ring, the diameter compatible of its size and rear end closes, and the material of use is rubber or stainless steel.

The utility model, the external diameter of the slide head of front end is less than the internal diameter of rear end, and after sliding tray installs sliding ring, front end can move to the afterbody of rear end from link by sliding ring.

The utility model, when using state, the screw thread of annular I groove of link can be threaded with nose threads, thus reaches the fixing of link and front end, when needs shrink, only need outward winding front end and link, the slide head of its front end is separated with link, and driving handle ring, passes through sliding ring, just front end gently can be slided into the inside of rear end, thus the object of bat contraction can be reached.

Detailed description of the invention

Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.

Fig. 1, Fig. 2, a kind of novel contractile bat of the utility model, be made up of handle ring (1), front end (2), rear end (4), chock plug (5), first straightway (21) and the handle ring (1) of front end (2) are welded to connect, rear end internal thread (43) and the chock plug (5) of rear end (4) are threaded, and are linked into an integrated entity between front end (2) and rear end (4) by link (3).Fig. 4, Fig. 5, the utility model, when using batting state, second straightway (23) of front end (2) is positioned at link segmental arc (31) inside, the segmental arc (22) of link segmental arc (31) and front end (2) is connected to become the segmental arc of bat, and nose threads (24) screw thread of front end (2) is fixed in annular I groove (33) of link (3).When bat needs to shrink, only need outward winding front end (2) and link (3), the slide head of its front end (2) (25) is separated with link (3), driving handle ring (1), by sliding ring (6), just front end (2) gently can be slided into the inside of rear end (4), thus can reach the object of bat contraction, its contraction state is for shown in Fig. 6, Fig. 7, Fig. 8.

Figure 10, Figure 11, shown in Figure 12, front end (2) is by the first straightway (21), segmental arc (22), second straightway (23) forms, second straightway (23) has nose threads (24), thus in use front end (2) can carry out screw thread with the screw thread of annular I groove (33) of link (3) and fix, fix front end (2) thus, the head of the second straightway (23) also has slide head (25), slide head (25) is provided with two sliding trays (26), the external diameter of the slide head (25) of front end (2) is less than the internal diameter of rear end (4), after sliding tray (26) is installed sliding ring (6), sliding ring (6) moves to rear end (4) afterbody from link (3) can be passed through in front end (2).Figure 14, rear end (4) is made up of rear end external screw thread (41), rear end straightway (42), rear end internal thread (43), rear end internal thread (43) and the chock plug (5) of rear end (4) are threaded, and its rear end external screw thread (41) is then threaded with link (3).

Figure 15, Figure 16, Figure 17, described link (3), comprise link segmental arc (31), link straightway (32), and in the inside of link (3), also there is annular I groove (33), annular II groove (34), annular I groove (33), in annular II groove (34), screw thread is set, the diameter of annular II groove (34) is larger than annular I groove (33), the junction between annular I groove (33) and annular II groove (34) is made to have an annular table terrace, thus form in inside the inwall that does not have drop after the rear end external screw thread (41) of rear end (4) and annular II groove (34) of link (3) are threaded, thus in the process of bat contraction, facilitate the slide head of front end (2) (25) from link (3), move to the afterbody of rear end (4).

The utility model, utilizes the upper sliding ring (6) installed of slide head (25), when bat does not use, very easily front end (2) can be may slide into the inside of rear end (4), thus can reach the object of bat contraction, therefore easy to carry.
