The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and cooperate accompanying drawing to give in detail explanation.

See also Fig. 1 to accompanying drawing 5, a kind of LED casing that the utility model provides shown in the accompanying drawing connects lock, be used for connecting the two adjacent LEDs casing, comprise the left lock and the right lock that are arranged on two adjacent LED casings, described left lock comprises left pedestal 1, nahlock 2, turning cylinder 3, handle 4, fixed screw 5, latch hook 6 and spring 7, described right lock comprises right pedestal 8 and lock hook seat 9;

Be provided with circular open on the two sides of described left pedestal 1, nahlock 2 rotating being arranged in the circular open, the eccentric position of nahlock 2 offers the first hole 21 and the second hole 22, turning cylinder 3 is fixed on the first hole 21 of relative nahlock 2, turning cylinder 3 passes handle 4 and latch hook 6 from outside to inside successively, handle 4 and latch hook are rotating being arranged on the handle, fixed screw 5 passes the second hole 22 and handle 4 and nahlock 2 and handle 4 is fixed, the retainer ring of described spring 7 is arranged on the fixed screw 5, the actuating arm of spring 7 is against on latch hook 6 bottom surfaces, and described lock hook seat 9 is suitable with latch hook 6.

In the present embodiment, lock hook seat is threaded connection and firmly is fixed on the right pedestal.

In the time will locking LED casing connection lock, with reference to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 4, handle 4 is pressed backward, handle 4 promotes latch hook 6 around turning cylinder 3 rotations in the process of pressing, owing to being connected with nahlock 2 respectively with fixed screw 5 by turning cylinder 3 on the handle 4, by two eccentric orfices both are fixed, therefore, in the process that handle 4 is pressed backward, nahlock 2 and then handle rotates together, and latch hook 6 compresses spring 7 in the process of rotating, because handle 4 and latch hook form the principle of eccentric clamping, after latch hook 6 is held lock hook seat 9, make the tension of whole connection lock, realize the amalgamation of LED casing.

In the present embodiment, with reference to accompanying drawing 1 and accompanying drawing 2, the rear end of latch hook 6 is provided with latch hook set screw 61, latch hook 6 comprises connecting rod and foot piece, latch hook set screw 61 is arranged on the foot piece, is provided with the screwed hole of adaptive latch hook set screw 61 on the foot piece, when latch hook 6 with after lock hook seat 9 cooperates, latch hook set screw 61 withstands on lock hook seat 9 rear ends, realizes the fine setting of lock distance by the rotation of latch hook set screw 61.

For further strengthening the fixing of handle 4 and left pedestal, in the present embodiment, with reference to accompanying drawing 1, be provided with location bead 42 on the described handle 4, be provided with the fixing hole of adaptive location bead 42 on the described left pedestal, in the time will locking LED casing connection lock, handle 4 is pressed backward, when moving to locked position, the location bead moves to position of positioning hole, and the location bead snaps in locating hole.

The location bead further stability when having strengthened whole connection and being locked in fixedly is set, and reminding user connects the use state of lock, prevents that handle 4 from pressing down the position, increased to connect the application life of locking.

In the present embodiment, with reference to accompanying drawing 1, left pedestal 1 comprises seat body 11 and block 12, and described block 12 is arranged on seat body 11 rear ends, is provided with on the block 12 to prevent an excessively groove that presses down of latch hook 6, and groove design has further guaranteed to connect the accuracy of latching operation.

Improvement project as above-described embodiment, described block 12 is welded on seat body 11 rear ends, is welded and fixed firmly, certainly, the utility model is the connected mode of limit stop 12 and seat body 11 not, also can adopt in other embodiments other releasable connections or is fixedly connected with.

In the time will opening the LED casing and connect lock, handle 4 is moved forward, latch hook upwards lifts whole latch hook under the restoring force effect of block 12 and spring 7, breaks off relations from lock hook seat 9 and goes out, and two LED casings can separate easily.

Improvement project as above-described embodiment, with reference to accompanying drawing 1, the end face of described block 12 is provided with bending part 121, and latch hook 6 places are provided with the inclined-plane, when latch hook presses down, the bending part 121 of block 12 props up the inclined-plane of latch hook 6, when opening the connection lock, the bending part of block 12 props up the inclined-plane of latch hook, under the effect of spring 7 restoring forces, latch hook upwards lifts, thereby latch hook is deviate from from lock hook seat 9 very easily.

In the present embodiment, the material of described left pedestal 1, latch hook 6 and right lock is stainless steel, and left pedestal 1, latch hook 6 and right lock use the stainless steel powder metallurgical disposal molding to become as a whole, realizes high accuracy and guarantees its more high strength.

In the present embodiment, with reference to accompanying drawing 1 to accompanying drawing 5, described handle 4 tail ends are provided with pressing tablet 41, be provided with anti-slip veins on the described pressing tablet 41, anti-slip veins can increase the frictional force of hand and handle 4, so that operate more steadily effectively, press or pull handle by one hand and realize the locking between the LED casing and unblank the realization full automatic working.

Quick connection lock handle 4 65 degree of tilting upward make its lockset open or all be no more than when closed the thickness of casing, avoid damaging in transportation, thereby and are contained in aviation case the inside and save the aviation case cost of manufacture that the packing die-cast cage is saved in the space.

Overall process is not wanted aid and only need just can effectively be realized fast the amalgamation of LED casing and dismounting with the one-handed performance lock, and is simple to operate, easy to use.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model manual and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
