Description

Contractile bat

Technical field

The utility model relates to field of athletic equipment, particularly relates to 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 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: contractile bat, by handle ring, front end, rear end, chock plug forms, its front end is by the first straightway, segmental arc, second straightway composition, first straightway of front end and handle ring are welded to connect, 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: described front end, the head of its second straightway also has gland, connected by link between front-end and back-end, described link, comprise link segmental arc, link straightway, and in the inside of link straightway, also there is annular I groove, annular II groove, annular I groove, in annular II groove, screw thread is set, screw thread and the rear end external screw thread of annular II groove of link are threaded connection fixing, and the internal diameter of rear end is greater than the external diameter of the gland of front end, the gland of front end can move to the afterbody of rear end from link.

Further, described front end, its gland has screw thread, the screw thread of annular I groove of link can with being threaded in the gland of front end.

Further, the external diameter of described front end gland part is greater than the external diameter of the second straight length portion of front end, makes the junction between gland 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.

The utility model, when using state, the screw thread of annular I groove of the link of front end can with being threaded in the gland of front end, thus reach the fixing of link and front end, when needs shrink, only need outward winding front end and link, the gland of its front end is separated with link, and the internal diameter due to rear end is greater than the external diameter of the gland of front end, driving handle ring, just front end gently can be moved to 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, the 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).

In order to understand intention of the present utility model better, Fig. 9, Figure 10, shown in Figure 11, front end (2) is by the first straightway (21), segmental arc (22), second straightway (23) forms, the head of second straightway (23) of front end (2) has gland (24), gland (24) has screw thread, object in use can carry out screw thread with the screw thread of annular I groove (33) of link (3) to fix, fix front end (2) thus, the external diameter of gland (24) part is greater than the external diameter of the second straightway (23) part of front end (2), the junction between gland (24) and the second straightway (23) is made to form an annular table terrace fallen, thus first straightway (21) of front end (2) can be made, segmental arc (22), second straightway (23) can pass through the inside of link (3), the gland (24) of front end (2) is not then by the inside of link (3).Figure 12, 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 13, Figure 14, Figure 15, described link (3), comprise link segmental arc (31), link straightway (32), and in the inside of link straightway (32), 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 gland of front end (2) (24) from link (3), move to the afterbody of rear end (4).

Composition graphs 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 gland (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 gland of its front end (2) (24) is separated with link (3), internal diameter due to rear end (4) is greater than the external diameter of the gland (24) of front end (2), driving handle ring (1), just front end (2) gently can be moved to 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.

Preferably, when the contraction state of bat, in order to fix front end (2) better in the position of rear end (4), one deck can be set on the inwall of rear end (4) afterbody and there is flexible rubber layer, thus the gland of front end (2) (24) can be made to be stuck in the afterbody of rear end (4).
