In order to achieve the purpose, the utility model provides a L ED display screen box concatenation locking lever device, including be used for fixing the lock seat on the box, be used for installing prevent changeing gasket and the spacing gasket between lock seat and the box, run through in the locking lever of through-hole on lock seat, prevent changeing gasket and the spacing gasket, the lock handle is installed to the tip of locking lever, be provided with the catching groove on the through-hole of lock seat, on the lock handle with the catching groove corresponds the position and is equipped with the knot and locates protrudingly, the knot is located protrudingly can pass through at axial relevant position the catching groove, still including set up in the lock seat with between the lock handle and the cover locate the spring on the locking lever.

Furthermore, an anti-rotation groove is formed in the lock rod, an anti-rotation protrusion is arranged on a through hole of the anti-rotation gasket, and the anti-rotation protrusion can be clamped into the anti-rotation groove.

Still further, a wrench is arranged on the lock handle.

Furthermore, the lock rod further comprises a clamp spring, and a clamping groove matched with the clamp spring is formed in the end portion of the lock rod.

Preferably, the number of the buckling grooves is two, and the number of the corresponding buckling protrusions is two.

Preferably, the lock rod is in threaded connection with the lock handle.

More preferably, the lock further comprises four screws, wherein the screws are used for fixing the anti-rotation gaskets, the limiting gaskets and the lock seat.

The utility model provides a display screen box assembly locking scheme compares in prior art, and it makes assembly, the dismouting of display screen box more convenient, swift for L ED display screen box's assembly quality is safe and reliable more.

fig. 2 is a schematic view of the structural installation of the embodiment of the present invention.

Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the following embodiments of the present invention will be briefly described with reference to the accompanying drawings, and it is obvious that the embodiments and the accompanying drawings are described only for illustrating the technical solution of the present invention, and the protection scope of the present invention is not limited to the embodiments and the accompanying drawings in the context that those of ordinary skill in the art can understand.

As shown in fig. 1, 2, for an L ED display screen box concatenation locking lever device, this concatenation locking lever device is used for the concatenation locking between the L ED display screen box, including being used for fixing lock seat 1 on the box, being used for installing prevent that lock seat 2 and spacing gasket 3 between 1 and the box run through in lock seat 1, prevent changeing locking rod 4 of through-hole on gasket 2 and the spacing gasket 3, lock handle 5 is installed to the tip of lock rod 4, be provided with catching groove 11 on the through-hole of lock seat 1, on the lock handle 5 with catching groove 11 corresponds the position and is equipped with detains protruding 51 in the knot position, detain protruding 51 in axial relevant position can pass through catching groove 11, still including set up in lock seat 1 with between the lock handle 5 and the cover is located spring 6 on the locking rod 4.

The lock rod 4 is provided with an anti-rotation groove 41, the through hole of the anti-rotation gasket 2 is provided with an anti-rotation bulge 21, and the anti-rotation bulge 21 can be clamped into the anti-rotation groove 41. In this way, the locking bar 4 has a positioning function in the axial direction under the restriction of the rotation preventing washer 2. In addition, the through hole on the limiting gasket 3 is slightly larger than the diameter of the locking rod 4, so that the locking rod 4 has a positioning function in the radial direction.

The wrench 52 is arranged on the lock handle 5, so that the lock handle 5 can be rotated by hands.

The lock rod is characterized by further comprising a clamp spring 7, wherein a clamping groove matched with the clamp spring 7 is formed in the end portion of the lock rod 4, and the lock rod 4 and the lock handle 5 are guaranteed to be firmly positioned in the axial direction.

The two buckling grooves 11 are axisymmetric, and the corresponding buckling protrusions 51 are axisymmetric. The lock rod 4 is in threaded connection with the lock handle 5.

The anti-rotation lock further comprises four screws 8, and the screws 8 are used for fixing the anti-rotation gasket 2, the limiting gasket 3 and the lock seat 1.

When carrying out display screen box concatenation in-process, the locking lever protrusion box, the operation workman can hold the box handle, realizes the pre-hanging of two piece upper and lower boxes, when needs were withdrawed the box with the locking lever, then only need with 5 rotatory certain angles of lock handle make detain position arch 51 and be in under the effect of the spring 6 restoring force through catching groove 11, alright realization were withdrawed locking lever 4 the box.

Use the technical scheme provided by the utility model, not only realized that the display screen box is quick, harmless concatenation, locking, when improving the concatenation precision, simplified the concatenation technology, and then also saved the cost of product.
