According to the utility model, under the elastic action of the torsion springs, the lock heads clasp table tennis table boards tightly, so that the table tennis table boards can not fall down, and when the table tennis table boards are required to be lowered, all that is needed is to hold the table tennis table boards by one hand and put the lock bodies down by the other hand to loosen the table tennis table boards; and the whole safety lock has a simple structure and low cost, is very convenient to use, and has good effect of fixing the table tennis table boards.

Description

Collapsible table tennis table safety lock

Technical field

The utility model relates to table tennis table accessory technical field, is specifically related to a kind of fixture of preventing that collapsible table tennis platen from toppling over of being used to.

Background technology

Table tennis is one of the highest sports item of popularity; Especially in China mass foundation is widely arranged; Table tennis table all is equipped with even in many families; Can stamp several innings between the kinsfolk when spare time comes, being highly suitable for lies fallow under the fast environment of current rhythm of life loosens, exercise.Because ping-pong table is all bigger, therefore can take bigger place, if putting a ping-pong table with regard to limited place originally in the life and work space always, that will certainly impact people's life and work.For this reason, present many ping-pong tables are all made folding, during use with the table tennis table plate development a ping-pong table, not the time spent with about two blocks of platens just fold up and can be placed on corner location, can not take too big space.But there is a shortcoming in present Foldable table tennis table, the table tennis platen is not fixed if promptly fold up the back, and platen may fall sometimes, not only possibly damage ping-pong table, also may cause some other security incident.And the device that is used for fixing platen at present more complicated all, and use inconvenience.

The utility model content

The technical problem that the utility model will solve is the defective to prior art, and a kind of collapsible table tennis table safety lock of simple in structure, easy to use, good fixing effect is provided.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of collapsible table tennis table safety lock, said table tennis table left-right symmetric; Comprise left platen and right platen; Left side platen is installed on the left foot frame, and right platen is installed on the right crus of diaphragm frame, and the left foot frame is connected with middle foot rest left side; The right crus of diaphragm frame is connected with middle foot rest right side; It is characterized in that: said safety lock comprises left safety lock and right safety lock, and on the upright pillar in the left side of foot rest, stood on the pillar on the right side of foot rest in the middle of right safety lock was installed in the middle of left safety lock was installed in; Left side safety lock is identical with right safety lock structure; Safety lock comprises lock body, tapered end and torsion spring, and lock body passes through the fixed rotating shaft crosswise fixed on the upright pillar of middle foot rest; The tapered end of a left side safety lock and right safety lock is all towards the centre of table tennis table; The mesosphere portion of torsion spring is fixed on the fixed rotating shaft, and on the column of foot rest, the other end was fixed on the lock body in the middle of an end of torsion spring was fixed on.

Preferably, tapered end is the hook formation that is bent upwards, and tapered end leans on the side in the middle of the table tennis table to be incline structure, and tapered end side in the outer part is a hook portion, and it is the perpendicular structure.

Preferably, tapered end leans on the side in the middle of the table tennis table to be the circular arc incline structure, and the top of tapered end is thin and the bottom is thick.

Preferably, the perpendicular hook portion of tapered end is provided with one and can prevents the cushion block that table tennis platen face breaks.

Lock body and tapered end adopt metal, plastic cement or timber to process.

The utility model can make tapered end tightly fasten platen under the effect of torsion spring elastic force, and platen can not fallen down, and will put down platen the time, holds platen on the other hand, and another hand is detained lock body can unclamp platen; Whole safety lock simple in structure, cost is low, and very convenient to use, and fixedly the effect of table tennis platen is also fine.

Among the figure, 1 is left platen, and 2 is right platen, and 3 is the left foot frame, and 4 is the right crus of diaphragm frame, and 5 is middle foot rest, and 6 is left safety lock, and 7 is right safety lock, and 71 is lock body, and 72 is tapered end, and 73 is fixed rotating shaft, and 74 is torsion spring, and 75 is cushion block.

The specific embodiment

In the present embodiment, with reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, said collapsible table tennis table safety lock; Said table tennis table left-right symmetric; Comprise left platen 1 and right platen 2, left platen 1 is installed on the left foot frame 3, and right platen 2 is installed on the right crus of diaphragm frame 4; Left foot frame 3 is connected with middle foot rest 5 left sides, and right crus of diaphragm frame 4 is connected with middle foot rest 5 right sides; Said safety lock comprises left safety lock 6 and right safety lock 7, and on the upright pillar in the left side of foot rest 5, stood on the pillar on the right side of foot rest 5 in the middle of right safety lock 7 was installed in the middle of left safety lock 6 was installed in; Left side safety lock 7 is identical with right safety lock 6 structures; Safety lock comprises lock body 71, tapered end 72 and torsion spring 74, and lock body 71 passes through fixed rotating shaft 73 crosswise fixed on the upright pillar of middle foot rest 5; The tapered end of left side safety lock 6 and right safety lock 7 is all towards the centre of table tennis table; The mesosphere portion of torsion spring 74 is fixed on the fixed rotating shaft 73, and on the column of foot rest 5, the other end was fixed on the lock body 71 in the middle of an end of torsion spring 74 was fixed on.

Tapered end 72 is the hook formation that is bent upwards, and tapered end 72 leans on the side in the middle of the table tennis table to be the circular arc incline structure, and tapered end 72 side in the outer part is a hook portion, and it is the perpendicular structure, and the top of tapered end 72 is thin and the bottom is thick.The perpendicular hook portion of tapered end 72 is provided with one can prevent the cushion block 75 that table tennis platen face breaks.Lock body 71 adopts metal, plastic cement or timber to process with tapered end 72.

Billiard table is received in the folded process, and the edge of platen is to the extruding of the circular arc limit of safety lock tapered end 72, and tapered end 72 circular arc limits are to lower slider, and until the right angle screens that platen gets into safety lock fully, cushion block 75 finally withstands platen, thereby accomplishes the snap close action to table; After billiard table was received folded the completion, table snapped in screens, and safety lock recovers level under the torsion spring effect, and perhaps safety lock is made for point of rotation left and right sides weight and is similar to, and under the gravity effect, recovers level voluntarily.When needing to launch billiard table, pull safety lock lock body 71 afterbodys with hand, safety lock is the fulcrum rotation with the fixed rotating shaft, and tapered end 72 unclamps, and pulls platen simultaneously, places back the user mode of ping-pong table.

Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
