Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic perspective view of an embodiment of the closing device of lamp casing of the present invention;
Fig. 2 is the front view of embodiment of the closing device of lamp casing shown in Figure 1.
The specific embodiment
The closing device of lamp casing of the present invention is applicable to that those have the light fixture of the housing that removably connects, one one of housing and in addition a part be fixed together by latch.The present invention utilizes lever principle, by leverage, can draw back latch with a less power, introduces the closing device of lamp casing of the present invention below in conjunction with embodiment in detail and how to implement.
As depicted in figs. 1 and 2, an embodiment for the closing device of lamp casing of the present invention, pedestal 1 is provided with lever 2, lever 2 is fixed on the pedestal 1 by a fulcrum pin 24, lever 2 can rotate around fulcrum pin 24, fulcrum pin 24 has spacing shim 241, restriction lever 2 moving axially at fulcrum pin 24.As shown in the figure, lever 2 comprises first arc section 22 that a horizontal segment 21 and horizontal segment 21 are tangent, and second arc section 23 tangent with first arc section 22, and fulcrum pin 24 is positioned at the junction of first arc section 22 and second arc section 23.First end 231 of lever 2, the i.e. end of second arc section 23, by pin 33 be rotationally connected be useful on the locking lamp casing latch 3, the pin of latch 3 31 cooperates with the locating hole of lamp casing, when inserting locating holes, realizes pin 31 locking to lamp casing, pedestal 1 is provided with the latch fairlead 32 adaptive with latch 3, and latch 3 moves back and forth in latch fairlead 32.
For activation lever 2 is rotated, on pedestal 1, also be provided with driven unit, this driven unit comprises push rod 4, and the push rod guide and limit that is arranged on the pedestal 1 overlaps 42,42 pairs of push rods 4 of push rod stop collar play guiding and spacing effect, push rod 4 is along the axially-movable of fairlead 4, have on the push rod 4 and the push rod guide and limit cover 42 spacing catch 43 that cooperate, first end 41 of push rod 4 is butted on second end 211 of lever 2, it is the end of the horizontal segment 21 of lever 2, push rod 4 is vertical with the horizontal segment 21 of lever 2, guarantees that 4 pairs of levers 2 of push rod have maximum power arm.In order to spur latch 3 with less power, the power arm of 4 pairs of levers 2 of push rod is greater than the resistance arm of 3 pairs of levers 2 of latch, and power arm can be 3-5 times of resistance arm, but is not limited to this multiple.Promotion push rod 4 for convenience, second end of push rod 4 has button 44, conveniently pushes push rod 4.
For latch 3 can be resetted after can removing in the driving force of lever 2, this switch also comprises elastic parts, in the present embodiment, this elastic parts comprises spring 5, and be arranged on spring reference column 52 on the pedestal 1, spring reference column 52 is fixed on the fixed head 51 vertical with pedestal 1, spring 5 is enclosed within on the spring reference column 52, spring 5 is butted on second end 211 of lever 2 by push rod 4 relative directions, preferably spring 5 is over against first end of push rod 4, make the power arm of 5 pairs of levers 2 of spring also bigger like this, lever 2 is resetted than being easier to.
Fig. 1 and Fig. 2, the schematic diagram of the lamp switch when being in the equilbrium position is when needs are opened this switch, push push rod 4 by button 4, promote lever 2 and rotate, lever 2 pulling latches 3, make the housing of the pin head disengaging light fixture of latch 3, realize opening of lamp casing, spring 5 is compressed by the effect of lever simultaneously, open lamp casing after, remove the power of pushing button 4, spring 5 recovers deformation, promotes lever 2 and resets, and returns to state shown in Figure 2.When lamp casing is closed, housing can compress the pin 31 of latch 3, latch 3 promotes lever 2 and rotates, spring 5 is compressed, when housing is compressed to the cooperation position of latch 3, under the effect of spring 5, promotes lever 2 and rotate, make pin head 31 be inserted into locating hole on the housing, thereby realize the closure of lamp body.
The closing device of lamp casing of the present invention utilizes the principle of lever, by rational selection fulcrum, equate according to moment, just can produce very big power at the far-end of fulcrum with less power and remove to draw back latch, thereby reach laborsaving, the compression reset function that adds simultaneously upper spring again, make the user can close fastening automatically closing when covering, thereby for the user saves time, promote efficient, also less simultaneously because of opening the force rate that needs, just can allow the assembling between the last lower house of lamp body can press tightlyer, make the decrement of sealing strip more, so just can well solve the sealing property problem of lamp body, the existing extraordinary water resistance of light fixture can be opened again very easily.
Light fixture of the present invention is to have the closing device of the lamp casing in the foregoing description.
In conjunction with the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
