A kind of upper-turn-type plate face frame supports device, it comprises support bar and ratchet, it also comprises stay pipe and plug-in type safety pin;
Described stay pipe suit support bar and support bar can move axially in stay pipe, the end that one end of stay pipe and support bar expose fixedly is equipped with stay pipe connector and supporting bar connector respectively, have notch on the tube wall of stay pipe, the ratchet inverse block fixedly is housed at tube wall inner face with the notch opposition side;
Described support bar section is inverted u-shaped, support bar in stay pipe movably the inverted u-shaped base of an end have notch, the support bar notch is consistent with the stay pipe notch;
Described ratchet is the four paws ratchet, and the four paws ratchet is arranged in the support bar notch.
Described four paws ratchet is provided with two big pawls and two unguiculuses of axial symmetry.
Described stay pipe section is a rectangle.
Described stay pipe side tube wall is provided with round tube hole, and described safety pin is inserted in this round tube hole insertedly.
Described stay pipe tube wall exterior is equipped with the annulus that can place safety pin.
Upper-turn-type plate face frame supports device of the present utility model has been cancelled spring, has simplified ratchet structure, provides more reliable and more stable mesa supports bar with the simplest structure, has reduced cost of production thus.
Upper-turn-type plate face frame supports device of the present utility model has been set up release binding, the hidden danger when having eliminated support bar of the prior art thus and using.
Upper-turn-type plate face frame supports device of the present utility model is applicable to the support of table top, window or door-plate etc., have simple in structure, reliable and stable, can effectively prevent table top from weighing down the advantage close, it makes simple, long service life, handling safety.
Description of drawings
Fig. 1 is the stereogram of a kind of upper-turn-type plate face frame supports device of the present utility model.
Fig. 2 is the front view of Fig. 1 bracing or strutting arrangement, is four paws ratchet positioning states.
Fig. 3 is the front view of Fig. 1 bracing or strutting arrangement, is four paws ratchet released state.
Number in the figure:
1 is stay pipe, and 2 is support bar, and 3 is the ratchet inverse block, and 4 is the four paws ratchet, and 5 is the plug-in type safety pin, and 6 is annulus, and 7 is chain, and 8 is the stay pipe connector, and 9 is supporting bar connector, and 10 is the stay pipe notch, and 11 is round tube hole, and 20 is the support bar notch.
The specific embodiment
Below in conjunction with drawings and Examples upper-turn-type plate face frame supports device of the present utility model is elaborated.
Referring to Fig. 1 to Fig. 3, a kind of upper-turn-type plate face frame supports device of the present utility model mainly is equipped with stay pipe 1, support bar 2, four paws ratchet 4, ratchet inverse block 3 and plug-in type safety pin 5.
Stay pipe 1 suit support bar 2 and support bar 2 can move axially in stay pipe 1.The one end fixed installation stay pipe connector 8 of stay pipe 1, the end fixed installation supporting bar connector 9 that support bar 2 exposes.Offer notch 10 on the tube wall of stay pipe 1, fixedly mount ratchet inverse block 3 at tube wall inner face with these notch 10 opposition sides.
As shown in fig. 1, support bar 2 sections are inverted u-shaped, and stay pipe 1 section is a rectangle.Support bar 2 in stay pipe 1 movably the inverted u-shaped base of an end offer notch 20, support bar notch 20 is consistent with stay pipe notch 10.
Four paws ratchet 4 is riveted in the support bar notch 20.As shown in Fig. 2 and Fig. 3, four paws ratchet 4 is provided with two big pawls and two unguiculuses of axial symmetry, and the angle of big unguiculus is respectively 120 ° and 170 °.
On the stay pipe 1 side tube wall round tube hole 11 is set, safety pin 5 is inserted in this round tube hole 11 insertedly.At the annulus 6 that can place safety pin 5 of stay pipe 1 tube wall exterior welding, its diameter is identical with round tube hole 11 diameters, with the safety pin 5 of just in time planting.Safety pin 5 can be connected on the stay pipe 1 by chain 7.
The use of upper-turn-type plate face frame supports device of the present utility model is as follows:
In conjunction with referring to Fig. 1 and Fig. 2, when stretching stay pipe and support bar, the four paws ratchet moves up along the inwall of stay pipe, and in drawing process, the big pawl of ratchet is run into the ratchet inverse block that is fixed on stay pipe one end, and ratchet turns to.Blocked by the ratchet inverse block owing to the four paws ratchet simultaneously, be unlikely to continue to rise and come off.And this moment stay pipe and support bar notch just in time coincide, another big pawl of symmetry exposes notch.Support bar is if reply at this moment, and the big pawl that the four paws ratchet exposes just in time blocks the stay pipe notch with the unguiculus that is pasting the stay pipe inwall, and the four paws ratchet reaches the lock point, realizes locating.Again safety pin is inserted the round tube hole of stay pipe this moment.
In conjunction with referring to Fig. 3, when wanting release, the support bar that stretches once more, four paws ratchet unguiculus is run into the ratchet inverse block, and ratchet turns to, another unguiculus of symmetry exposes notch, support bar arrived the upper limit and can't continue to rise this moment, pushed back support bar then, and the unguiculus that exposes is continued to promote to make ratchet continue to turn to by notch, to be flipped to certain angle, support bar will be got back to the position before stretching smoothly.
Before release, will extract safety pin earlier, otherwise the release back support rod moves and runs into safety pin and will halt, so just played safety effect.When the utility model is used for the operating desk mesa supports, in order to prevent to use safety pin seek nowhere and the table top playback after the safety pin that hanging run into electric fixtures, after extracting safety pin, the safety pin insertion can be placed in the annulus that is welded in the stay pipe outside.Safety pin can be with a chain bolt on stay pipe, to prevent that safety pin drops in the operating desk because of carelessness in the use.
In sum, upper-turn-type plate face frame supports apparatus structure of the present utility model is simple, reliable and stable, can prevent effectively that table top, plate face or framework from closing from weighing down, it makes simple, long service life, handling safety can be widely used in the support of various table tops, window or door-plate etc.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
