Problems solved by technology

[0002] With the development of society and the continuous improvement of living standards, LED displays have also moved from the screen to life. From large-scale performances to small collective celebrations, LED displays can be seen. In order to achieve performance effects, people The requirements for rental LED displays are getting higher and higher, especially for the quick disassembly and assembly of LED displays, safety and reliability, and convenient construction and maintenance. The current LED display cabinets have locking devices spliced ​​in the left and right directions and The upper and lower locking devices are the same, that is, the simple lock lever and the lock mother piece are locked together. One person needs to hold the box, and the other completes the locking. As a result, two people are required to cooperate in locking and opening, which is a waste of manpower and low locking efficiency. , the locking degree is not enough through the common lock lever and lock mother piece, and the LED display screen is spliced ​​by multi-layer and multi-block unit boxes. In order to install at a high place, it is necessary to use additional climbing tools or set additional climbing devices on the unit box body. In the prior art, the unit box itself cannot be used for climbing, so the installation of the LED display screen in the prior art is complicated and difficult. Low installation efficiency

Embodiment 1

[0023] In this embodiment, an LED display screen is provided. The LED display screen is formed by splicing a plurality of unit cabinets left and right. In this embodiment, the left and right unit cabinets are taken as an example, as shown in figure 1 As shown, viewed from the back of the LED display screen, the right one is the first unit box body 1, the left side is the second unit box body 2, the left side of the first unit box body 1 is provided with the first lock body 3, the second unit box body A second lock body 4 is provided on the right side of the unit box body 2, and the positions of the first lock body 3 and the second lock body 4 are relatively corresponding. The first unit box body 1 is provided with a mounting seat for installing the first lock body 3, and the mounting seat is provided with a mounting hole. Specifically, the mounting seat is a protruding rib on the first unit box body 1, and the mounting seat is provided on the rib. hole, the first lock body 3 i...

Embodiment 2

[0035] This embodiment differs from the first embodiment in that the structure of the handle 31 is different.

[0036] Such as Figure 6 As shown, both ends of the handle 31 are bent, and the bent end connected to the lock bar 32 is consistent with the handle 31 of the first embodiment, and has a racetrack-shaped mounting hole. The other bent end of the handle 31 is provided with a round through hole. In order to install the handle 31, the first lock body 3 also includes a connecting piece 35. The connecting piece 35 includes a knob 351 and a rotating shaft 352. The knob 35 is provided with shallow threads, and one end of the rotating shaft 352 is Vertically fixed at the center of the knob 351, the other end of the rotating shaft 352 is provided with threads, correspondingly, the first unit box body 1 is provided with a threaded hole, and the rotating shaft 352 passes through the round hole of the handle 31 and is fixed on the first unit box body by threads 1, and the rotatin...

Abstract

A light emitting diode (LED) display comprises a first box unit (1) and a second box unit (2) attached to each other from the left and the right. A first lock (3) and a second lock (4) are disposed on the first box unit (1) and the second box unit (2), respectively. The first lock (3) comprises a handle (31) and a lock rod (32). The second lock (4) comprises a washer. Since the first lock (3) can be directly installed on the first box unit (1) without an additional fixing base, the space of the box is saved. A cutting surface is provided at a locking end (322) of the lock rod, and configured to fit and connect, by the rotational handle (31), the lock rod (32) to a locking hole (41), resulting in highly efficient locking. A positioning block (11) is disposed at a lower side of the handle (31) which is only capable of rotating between a horizontal position and an upward vertical position, but not rotating downwards, facilitating to lock the handle (31) and being used for climbing.
