Figure.
Referring to Fig. 7, for the movable plate of enclosed structure, fixed plate, fixation before LED display provided in an embodiment of the present invention
Bearing and unit back frame structure schematic diagram.
Referring to Fig. 8, the unit backrest backside structure for enclosed structure before LED display provided in an embodiment of the present invention is shown
It is intended to.
Pedestal 14 is provided with the second through-hole, and lock pin 9 is plugged in the second through-hole, i.e., lock pin 9 pass through the second through-hole and with bottom
14 elastic connections of seat, when lock pin 9 moves, the second through-hole can play guiding role.
Further, when the second elastomeric element 13 is between pedestal 14 and inclined-plane, 13 first end of the second elastomeric element with
14 one end of pedestal is fixedly connected, and 13 second end of the second elastomeric element is fixedly connected with lock pin 9, and the second elastomeric element 13 is in compression
State；When the second elastomeric element 13 is between pedestal 14 and guide rod 4,13 first end of the second elastomeric element is solid with 14 one end of pedestal
Fixed connection, 13 second end of the second elastomeric element are fixedly connected with lock pin 9, and the second elastomeric element 13 is in tensional state.
In the embodiment of the present invention, position-limited block is fixedly installed on lock pin 9, the second elastomeric element 13 is limited in limiting block
Between piece and pedestal 14.
Split pin can also be set on lock pin 9, as shown in figure 4, in the embodiment of the present invention, there are two split pins and difference position
In 14 both sides of pedestal, specifically, when split pin is with limit catch homonymy, limit catch makes between split pin and pedestal 14
Lock pin 9 is obtained to move up and down in fixed range, in case lock pin 9 is moved because of the overaction of the restoring force of the second elastomeric element 13
Interfere with other components.
Further, fixed plate 16 is vertically fixed in unit backrest 3, and 16 first end of fixed plate and fixed plate 16 second
The first side wall 17 and second sidewall 18 are respectively arranged on end, movable plate 11 is arranged with 16 parallel misalignment of fixed plate, movable plate 11
It is provided with third side wall 19, and third side wall 19 is between the first side wall 17 and second sidewall 18.
The first side wall 17, second sidewall 18 and third side wall 19 are equipped with perforation, and pivot pin 21 passes sequentially through perforation across the
One side wall 17, third side wall 19 and second sidewall 18 so that fixed plate 16 is fixed on movable plate 11.
As shown in fig. 6, in the embodiment of the present invention, magnetic plate 10 can also be correspondingly arranged perforation.
First elastomeric element 12 is socketed on pivot pin 21, and between the first side wall 17 and third side wall 19, in certainly
Right state.
First elastomeric element, 12 first end is fixedly connected with pivot pin 21,12 second end of the first elastomeric element and the first side wall 17
It is in contact.
Movable plate 11 can be moved along 21 opposing fixed plate 16 of the first pivot pin under external force.
Specifically, when magnetic plate 10 is sucked in magnetic tool, and movable plate 11 is made to be moved to 2 direction of unit box, movable plate 11
It being moved along 21 opposing fixed plate 16 of the first pivot pin so that the first elastomeric element 12 is compressed, after magnetic tool is removed, movable plate
11 can be moved to home position under the action of the first 12 restoring force of elastomeric element along the first pivot pin 21.
In embodiments of the present invention, in order to save space with the small space between adaptation unit backrest 3 and unit box 2,
Third through-hole is set in unit backrest 3, hold-down support 20 is provided on third through-hole edge, fixed plate 16 and movable plate 11 are equal
It is arranged in third through-hole, fixed plate 16 is connect with hold-down support 20.
As shown in fig. 7, fixed plate 16 and hold-down support 20 be by screw connection, in order to reinforce fixed effect, fixed plate 16
On be provided with buckle, fixed plate 16 also passes through buckle and is clamped with hold-down support 20.
The quantity of the first pivot pin of the present invention couple 21 is not specifically limited, for example, the quantity of the first pivot pin 21 can be two.
Fig. 9 is please referred to Figure 13.
Further, enclosed structure further includes before LED display：Push and pull component 7.
It is connected between adjacent cells backrest 3 by pushing and pulling component 7, push-and-pull component 7 is used to adjust between adjacent cells backrest 3
Distance.
The present invention is to adjust the distance between unit backrest 3 and unit backrest 3 by pushing and pulling component 7, further adjusts LED
Display screen splices gap, because unit box 2 is in a pre-installation, engineering staff pre-installs from front and mixes up the position of unit backrest 3
It sets, so after unit box 2 is installed in unit backrest 3, need to be only finely adjusted to about 3 or so unit backrests can be very
Mix up the piece of entire LED display soon, this method adjusts that space is sufficient, easy to operate and accurate positioning.
In addition, unit backrest 3 can be in the unit of bearing part equipment, such as：Power supply and board, to mitigate unit box
2 dead weight keeps unit box 2 more light adjustable.
Further, enclosed structure further includes before LED display：Connecting bracket 8.
Connecting bracket 8 is used to unit backrest 3 being fixed on object to be fixed, for example, connecting bracket 8 can be wall,
It may be frame.
Further, enclosed structure further includes before LED display：Locking snap-gauge 6, shaft and fixed pin.
Fixed pin penetrating element backrest 3, and fixed pin first end is fixedly connected with 2 back side of unit box, shaft is through single
It first backrest 3 and is rotatably connected with unit backrest 3, locking snap-gauge 6 is fixedly connected with shaft one end, and can rotate to and fixed pin
The position that second end is blocked.
It is understood that because of shaft penetrating element backrest 3, shaft both ends are located at 3 both sides of unit backrest,
One end by stirring shaft can drive the locking snap-gauge of the shaft other end to rotate, when the rotation of locking snap-gauge 6 to fixed pin card
When position firmly, when preventing from safeguarding or fortuitous event lower unit babinet 2 falls off from unit backrest 3.
In addition, as shown in figure 8, in the embodiment of the present invention, enclosed structure further includes before LED display：Spring and limit hole.
Limit hole is arranged at 3 back side of unit backrest, and spring one end is connect with locking snap-gauge 6, and the other end is connect with 3 back side of unit backrest,
So that locking snap-gauge 6 is around shaft when rotating, spring plays tensioning function to locking snap-gauge 6, and locking snap-gauge 6 is from " locking shaft "
During " unlock shaft ", spring is stretched, and inherent contraction elasticity promotes locking snap-gauge 6 to be rotated up around the shaft to rest in
It limits on hole wall, will not spring back.
Wherein, only stirring for shaft need to can be realized using general tool, so control locking snap-gauge 6 realizes locking reconciliation
Lock is more convenient.
Further, push-and-pull component 7 is left-right rotary screw rod, can will be left in order to realize preferable fixation and regulating effect
The quantity of right handed screw is set as multiple.
More than, the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to aforementioned reality
Applying example, invention is explained in detail, it will be understood by those of ordinary skill in the art that：It still can be to aforementioned each
Technical solution recorded in embodiment is modified or equivalent replacement of some of the technical features；And these are changed
Or it replaces, the spirit and scope for various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution.
