Abstract
The utility model relates to a connecting device. The connecting device is arranged between display units which form a display screen, the connecting device is divided into a left part and a right part, and the connecting device is made of a steel material. The connecting device comprises a box body of display units. An installation position is reserved on the side wall of the box body. One part of the connecting device is a convex bolt which is arranged on the surface of the side wall of one display unit, A bolt hole seat which is matched with the convex bolt, and a positioning and locking device are arranged in a step-shaped installation positioning cavity on the side wall of the other display unit. Through holes which are matched are arranged on the convex bolt and the bolt hole seat along a radial direction. The through holes are matched with the positioning and locking device which comprises a guide block, a locking rod, and a position limiting pin. When the connecting device is installed, the display units are hung to arrive at a position, the convex bolt is pushed into the bolt hole seat, the locking rod is inserted to arrive at the position, and is rotated 90 DEG, i.e. two units of the display units are locked. The connecting device has simple structure, small volume, firm and reliable connection, large bearing capacity, and simple and convenient connecting and disassembling operation. A connecting structure between the display units is greatly simplified.
Description
Technical field
The utility model relates to the coupling arrangement between a kind of display unit that constitutes display screen, is meant the coupling arrangement between a kind of Led display unit especially.
Background technology
Existing giant-screen Led display screen all is to be made of the display module in the specific casing of packing into, and this casing has been formed a display unit.When display unit is assembled into display screen, need the specific frame-type erecting frame of size making according to the display area of user's setting, be provided with installing frame in the body frame with the display unit coupling, between the display unit, all adopt bolt to be connected between display unit and the erecting frame, produced thus and installed that loaded down with trivial details difficulty is big, the drawback of dismounting maintenance difficult.Waste is especially, manufacturer and user need to check and accept at factory's assembling back test-run a machine before the product export, producer need make a special-purpose erecting frame for this reason, by checking and accepting and display unit being pulled down shipping behind user's field of employment, make waste product and handle because the erecting frame that producer makes can't whole Transporting can only cut to decompose, thereby the user also needs the on-the-spot same erecting frame of making again.
Summary of the invention
The purpose of this utility model provides a kind ofly to be made between the display unit, assembling, convenient disassembly, easy coupling arrangement between display unit and the erecting frame.
Designed coupling arrangement between a kind of display unit according to above-mentioned purpose, comprise display unit box, also comprise and be divided into two-part coupling arrangement, these two parts lay respectively at going up of two display units being joined together or down, on a left side or the right panel, during design, can or descend on a display unit box, left or right, perhaps go up or descend, a left side or the right latch that is provided with projection simultaneously, at this moment, the following of another display unit box relative with latch or on, right or left, perhaps go up or descend, a left side or the right localization cavity that is provided with the indent of backward opening simultaneously are provided with pin hole seat and location with the latch coupling in this cavity, locking device.This latch is fixed on the display unit box by bolt or bearing pin, have on the latch and axial vertical through hole, and localization cavity also is fixed on the casing by bolt or bearing pin, and has a through hole that supplies latch to penetrate on the cavity place cabinet panel.The pin hole seat is fixedlyed connected with localization cavity by bolt or bearing pin, have on the pin hole seat wall one with latch on the through hole that is complementary of vertical through hole.
Described location, locking device comprise guide holder, locking bar, spacer pin, guide holder is fixedlyed connected with localization cavity by bolt or bearing pin, have guide groove in the guide holder, can only folk prescription be positioned at the middle part of locking bar to spacer pin by guide groove for locking bar unidirectional turnover.Locking bar leading portion in location, the locking device and the through hole on latch and the pin hole seat are clearance fit, and leave the gap that spacer pin is rotated freely between guide holder and pin hole seat wall.In addition, locking bar is positioned at the outer end of guide holder and is provided with handle.
After during installation display unit lifting being put in place and latch being pushed the pin hole seat, locking bar inserted put in place and half-twist promptly links together two display unit unit and pins.As seen, the utility model is simple in structure, and volume is little, firm and reliable connection, and bearing capacity is big, and connection and disassembling section are simple, easy, convenient, have greatly simplified the syndeton between display unit.
Description of drawings
Accompanying drawing 1 is the partial assembled synoptic diagram of the coupling arrangement part after connecting between two display units of the utility model; Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to partial schematic sectional view; Accompanying drawing 3 is partial assembled complete section schematic top plan view of the utility model pin hole seat and location, locking device; Accompanying drawing 4 is that the B-B of accompanying drawing 3 is to partial schematic sectional view.
Specific embodiments
The utility model be used for two or more Led display units up and down or about connect, therefore on a rectangular display unit 1, when being outwardly directed latch 4 in a side, be installing and locating cavity 2 at the opposite side of latch extension line, as shown in Figure 1.Connect up and down in this way, then downward or upward step surface is provided with pin hole seat 3 with the latch coupling in the installing and locating cavity; Connect in this way, then in the installing and locating cavity to the right or step surface left be provided with pin hole seat with the latch coupling.The xsect of latch and pin hole seat can be rectangle, circle or other suitable shapes, has the through hole for locking bar 6 turnover on pin hole seat and latch accordingly.Spacer pin 7 on locking bar and guide holder 5, the locking bar has been formed location, locking device, because the existence of spacer pin and locking bar distal handle, locking bar can not withdraw from guide holder.During installation, leave the gap of rotating between guide holder and pin hole seat for spacer pin; During use, after display unit lifting being put in place and latch being pushed the pin hole seat, locking bar inserted put in place and half-twist promptly links together two display unit unit and pins.
In order to guarantee load-bearing capacity, all parts of coupling arrangement are all to adopt steel to be advisable.The utility model also can adopt up and down connect, about connect the version of implementing simultaneously.
