Description

Automatic rolling-up and fixing device for table tennis net

The utility model relates to a kind of table tennis net and furls automatically and fixture, is cylinder and the characteristic assembly that cooperates the outer end with two groups of sandwich sheets, the action that it can be fixed in a side fast and finish installing.

Because under the prerequisite situations such as the character of motion and needed steric requirements, table tennis is one of sports events that Chinese made earnest efforts very much always, play table tennis required utensil except ball, outside the bat, also be suitable for the net of ball table and separation usefulness, the net and the fixed form thereof of present form of ownership, it all is fixed mount with two similar C type folders, be fixedly arranged on ball table both sides respectively, central authorities use and strut net, but all users all know, utilize C type clamping regularly, the placement screw that must not stop a few, even tens of circle can be firm, when this implements effort, cause very inconvenience of use, in addition, when being tightened repeatedly, regular meeting is acute excessively because of the application of force, cause the destruction desktop, the utmost point does not conform to practicality; And collection the time must repeat unscrew after can take out, generally again net is rolled up on the side lever of geometrical clamp then, this causes a lot of trouble again, and net continues to be exposed to the external world, and is also impaired easily, so on traditional design, obviously has weak point.

The purpose of this invention is to provide that a kind of net easy for installation can furl in cylinder, the time saving and energy saving table tennis net that does not damage desktop again furls and fixture automatically.For making masses can understand architectural feature of the present utility model and effect, now contrast accompanying drawing, be described below, wherein:

Fig. 1 is a stereo appearance figure of the present utility model;

Fig. 2 A is assembled sectional view of the present utility model left side;

Fig. 2 B is assembled sectional view of the present utility model right side;

Fig. 3 is an enforcement illustration of the present utility model.

See also shown in each accompanying drawing, the utility model mainly comprises two groups of anchor clamps that are the L type, main body is a sheath body (1), (5) in conjunction with perpendicular cylinder (2), (6), two sheath bodies (1), (5) structure is all identical, be made as upper clip (11) endways, (51), the below is that each is sheathed with movable block (4), (8), its structure is detailed shown in Fig. 2 A and Fig. 2 B, movable block (4), (8) top penetrates sheath body (1), (5) default circular groove in, spring (41), (81) the difference hook is in sheath body (1), (5) Nei fixing point and movable block (4), (8) Nei Bu connecting rod (42), (82), be to make movable block (4), (8) has lasting elastic force upwards, movable block (4) again, (8) end all extends lower clamping piece (43), (83), itself and upper clip (11), (51) form a U-shaped space.

Central authorities at cylinder (2) are provided with a rotating shaft (22), loam cake (21) covers in top, and the upper end of fit rotating shaft simultaneously (22), it in the bottom of rotating shaft (22) wind spring (23) that is positioned at the inside of cylinder (2) in conjunction with, and rotating shaft (22) be made as the bottom that passes cylinder (2) bottom, sheathed again in this place with a knob (24); The one end system of net (3) is incorporated in the rotating shaft (22), and the other end is stretched out by the side, and combination is with an arc plate (31).Medial margin at cylinder (6) is provided with a vertical fracture (7), and unification loam cake (61) sealing can be covered in top.

During use, can be with the movable block (4) of two groups of anchor clamps, (8) pull down a little, make upper clip (11), (51) with lower clamping piece (43), (83) distance is greater than the width (shown in Fig. 2 right part) of ball table (9) between, loosen subsequently, movable block (4), (8) just can be because of spring (41), (81) elastic force and rebounding, be can cooperate upper clip (11), (51) grip in table side (shown in Fig. 2 left part), after fixing two anchor clamps, arc-like sheet (31) is pulled outwardly, the related net (3) that makes exposes cylinder (2), being pulled to cylinder (6) locates, from top to bottom arc-like sheet (31) is inserted cylinder (6) inside, net (3) is then located between crack (7), covers the lid (61) that closes again, can form state as shown in Figure 3, be available for users to use.In the time will collecting, as long as pull down, because the end of net (3) system is fixedly arranged on rotating shaft (22) with reverse order, when stretching, wind spring (23) so can recover automatically when loosening, is regained net (3) simultaneously and is rolled up in rotating shaft (22) by compression, and be concealed within the cylinder (2), in addition, if when the elasticity of wind spring (23) is not enough, can utilize knob (24) drive rotating shaft (22), mode with hand adjustment reclaims, and also can reach the purpose of collection.

In sum, the effect that the utility model obviously has traditional product and do not had can be utilized Easy mode is reached purpose fixing and installing, it can furl net again automatically, time saving and energy saving, have practical value, can not destroy again the ball table when other uses and can effectively preserve net not being damaged, therefore practicality of the present utility model has really met the requirement of Patent Law, and structure of the present utility model never sees earlier publication or other people open use is arranged, therefore, the utility model should meet the requirement of getting permission patent.
