Bar 3, the connecting rod 3 are rotatably provided in second lock body, alternative to be rotated around the second rotating shaft 2 with beyond described the
The interface of two casings 10 and first casing 9.
First rotating shaft 5 described in the present embodiment is arranged in mounting groove, and the opening of the mounting groove is locked towards described second
Body.
Preferably, unlocking link 7 is provided with first lock body 6, the unlocking link 7 has and first lock body
6 be hinged jointed shafts, and the connecting rod first end swung and the end of connecting rod second can be realized with the rotation of the jointed shaft, it is described
Connecting rod first end can be relatively rotated with the hook 4 and is connected, can control the hook 4 swung, the end of connecting rod second by
The surface of first lock body 6 is extend out to outside first lock body.
The handle 1 for controlling the connecting rod 3 is additionally provided with second lock body, the handle 1 passes through angle card
Position rotating shaft 8 is connected with second rotating shaft 2.The outer surface of angle screens rotating shaft 8 is in cam face, the handle 1 have to
On the first position lifted and the second place for being depressed into bottom, at the second place, the protuberance court of the cam
To the direction of the first lock body 6.
The skewed slot for accommodating the connecting rod 3 is provided with second lock body, energy is provided with second rotating shaft 2
The connecting rod 3 is enough set to retract into the torque spring of the skewed slot.The bottom land of the skewed slot, which has, to be used to install described second
The shaft mounting hole of rotating shaft 2, second rotating shaft 2 can be rotated in the shaft mounting hole.
The skewed slot is towards being provided with the groove that can pass through the connecting rod 3 in the side wall of first lock body 6.
Meanwhile a kind of splicing LED screen is also provided in the present embodiment, it includes some unit screen bodies, the adjacent unit screen
Implicit connection lock as described above is attached between body.The body of unit screen described in the present embodiment is as the first casing 9 and
Two casings 10.
The specific work process of implicit connection lock described in the present embodiment is described below.
Handle 1 is attached with connecting rod 3 by the second rotating shaft 2.When handle 1 is rotated up, the band of angle screens rotating shaft 8
The dynamic rotation of connecting rod 3 protrusion casing top.
Being unlocked by pressing connecting rod 7 can drive hook 4 to be rotated to move up release hook 4.Open and connect in handle 1
Extension bar 3 can be to be directly attached, when connecting rod 3 enters the first casing 9 when protruding from the second casing 10 with the first casing 9
Bottom i.e. hook 4 lower grooves in can be moved all the way up along groove, due to hook 4 bottom shape with
The cylindrical shape of connecting rod 3 forces hook 4 to anticlockwise and to be moved up around first rotating shaft 5 with credit union, when connecting rod 3 is entered
The initial bit of hook 4 can be returned to because torque spring is turned right and is pressed downward by entering to hook 4 during 4 the inside of hook
Put, this process blocks process for hook 4.
After connecting rod 3 is snapped onto in hook 4, handle 1 is pressed downward, because the outer surface of angle screens rotating shaft 8 is in cam
The reason for shape, can force connecting rod 3 to move down, therefore hook 4 be tensed can downwards, because hook 4 passes through first turn
Axle and the first casing 9, which coordinate, quite to be fixed, so the first casing 9 can be made to be fastened with the second casing 10.
Specifically, installation operation and the process of disassembling section are as follows：
Installation operation：
Under non-installment state, handle 1 is located in casing, i.e., in down position, connecting rod 3 is due to the edge of torque spring
Therefore it can be constantly in skewed slot.When preparing ampere-hour, handle 1 has been broken upwards, because the angle of angle screens rotating shaft 8 limits, meeting
Drive connecting rod 3 to break upwards and be vertically to the top of the second casing 10.Now keep the position of handle 1 constant by the second casing 10
Top upwards, the bottom of the first casing 9 is headed into, due to there is a guiding of mounting groove and the hook 4 of inside, connecting rod 3 then can be with
Manpower pushes up and is caught in the inside of hook 4 upwards, and heading into for connecting rod 3 can make hook 4 be turned clockwise necessarily around first rotating shaft 5
Angle, as the rotation first rotating shaft 5 of hook 4 can produce certain displacement upwards so as to open hook 4.When connecting rod 3
When pushing into the top inside hook 4, hook 4 can be because the torsion of torque spring forces hook 4 to return to original position.Then may be used
It is pressed downward with handle 1, connecting rod 3 is tightened up downwards due to the outer surface of angle screens rotating shaft 8 is in cam face, by
Hook 4 has been hook up in connecting rod 3 so hook 4 can be driven to move down, because hook 4 has contacted the first casing 9
Bottom (by design, it can be changed so the bottom of the first casing 9 and the top of the second casing 10 can be forced to press close to inflexibly
Value of interference fit, so as to realize the compression of two casings), it is achieved thereby that utilizing the tension after the clamping of hook 4.By upward
Move downwards two of handle 1 actions realize the first casing 9 and the second casing 10 " pre-hung ", " locking ", installation process.
Disassembling section：
In the state of two casings have been installed and are fastened.Now casing be by the cooperation of hook 4 and connecting rod 3 and
The state of locking.When preparing to dismantle the cooperation of two casings, handle 1 has been broken upwards, connecting rod 3 can by handle 1 to
On broken and moved up a segment distance, so as to disengage the contact position of hook 4.Now due to there is torsion inside hook 4
The reason of spring and be always maintained at this position.Can be taken advantage of a situation when handle 1 is opened with hold with a firm grip handle 1 thumb or other
Finger-joint touches unlocking link 7, and unlocking link 7 can be rotated around the jointed shaft for fixing it, in the connecting rod of unlocking link 7
First end, has projection, the elongated slot cooperation of projection and hook, and this cooperation can make unlocking link 7 drive hook 4
It is dynamic, so as to which release hooks 4 coordinate with connecting rod 3.Now can be with the cooperation of two casings of disengagement downwards.Disengage the cooperation of casing
Afterwards, hook 4 can spring back to original position due to having unclamped the pressing of unlocking link 7.And handle 1 then can downwards be broken and take in second
Inside casing 10, now connecting rod 3 can be returned to inside skewed slot because of torque spring.
In description herein, it is to be understood that term " on ", " under ", " right side ", etc. orientation or position relationship be based on
Orientation shown in the drawings or position relationship, it is for only for ease of description and simplifies operation, rather than indicates or imply signified dress
Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to the utility model
Limitation.In addition, term " first ", " second ", are used only for being distinguish between in description, not special implication.
