Second boss 43 on boss, the pedestal, first boss and second boss are cylindrical and are hollow structure；Two pull rods
5 bottom end is connected with the pedestal 41 of axle sleeve.Such as Fig. 2 and Fig. 3 it is found that magnet set 31 also includes cylindrical 311 He of pedestal
Boss 312, the shape of magnetic receiver are adapted with the cavity shape of the pedestal of axle sleeve and first boss.The bottom end of shaft 20 is provided with
Internal thread, the boss 312 of magnet set 31 are provided with internal thread, and the boss 312 that 20 bottom end of shaft and magnet cover is threadedly coupled.
Referring to Fig. 6, the lower surface of cross bar 11 is provided with a cylindrical section 115, the second boss 43 of axle sleeve 4 is inserted into the cylinder
In 115；A spring 89 is equipped in the cylinder 115, the top and the lower surface of cross bar 11 of spring 89 offset, the bottom end of spring 89
It offsets with second boss 43；The shaft 20 is passed through from the spring 89.When operation eccentric handle 6 so that guide rod 5 is raised above
When, spring is more steady when guide rod 5 being caused to increase by the certain elastic force of compression generation, avoids guide rod 5 and rises too fast and cause lamp
Plate accidental damage.
As shown in fig. 7, for the ease of the installation of spring, the top of the second boss of axle sleeve is equipped with first annular groove 432,
The bottom of spring 89 is arranged in first annular groove.
Referring to Fig. 6, being set in first boss there are one first annular flange 431, first annular flange 431 is located in shaft
The second annular flange 301 is provided at lower section, be provided with second annular groove 302 in the second annular flange 301 (does not mark in figure
Number), be provided with several balls 82 (2 balls can be observed in Fig. 5 visual angles) in second annular groove, the top of each ball 82 with
The lower surface of first annular flange 432 offsets.Pass through the setting so that shaft is propped up at bearing and at several balls
It holds, it is more steady in shaft rotation process so as to ensure that.It, (please inserted with four pins 84 in second boss in practical application
Refering to Fig. 3 and Fig. 6), the outer wall of this four pins is abutted with the lower surface of the second annular flange 301, so as to play countershaft
Further support.
As shown in figure 8, further, the eccentric handle 6 includes an ontology 61, and the both ends of ontology are respectively arranged with one
A eccentric wheel 62, top of each eccentric wheel 61 respectively with a guide rod are hinged.For the ease of operation, the ontology of eccentric handle leads to
It is standing to be set to：One root long arm 611, long-armed both ends are provided with a galianconism 612 with being integrally formed respectively.Each eccentric wheel difference
It is connected with that corresponding galianconism by axis pin and (depicts pin shaft hole 621 in Fig. 8, during assembling, which is inserted into pin shaft hole 621
In), it can be rotated so as to fulfill eccentric handle 6 around trunnion axis, be further driven to the lifting of two guide rods.
Referring to Fig. 3, the side wall of the magnet set 31 offers at least one pin hole (identical with 313 position), axle sleeve
It corresponds to and vertically opens up respectively at each pin hole there are one waist-shaped hole 411 on side wall, be inserted into that there are one pins in each pin hole respectively
It follows closely (313).Each pin is stretched into that corresponding waist-shaped hole 411, by the setting, is avoided magnetic receiver and is rotated, and is protected
Card magnet holder only moves up and down.
Referring to Fig. 1, further, there are one washers 441 for the bottom setting of axle sleeve 4, and the bottom of each filler strip is set respectively
Gasket 141 there are one putting.As shown in Figure 7, the pedestal bottom end tool of axle sleeve is there are one annular flange 44, for connecting washer.Pass through
Setting gasket plays protective action, and lamp plate is damaged by pressure when avoiding dismounting lamp plate.Preferably, above-mentioned washer and two gaskets are
Silicagel pad.
Further, the both ends of cross bar 11 are connected respectively by a brace 12 with the top of that corresponding root upright bar 13.
The setting causes stent substantially arcuate, improves the intensity of stent, can bear the external force of bigger.
Operation principle described briefly below：During dismounting, preceding maintenance work is placed among LED display lamp plate 91 to be safeguarded first
Position, two filler strips 14 support adjacent two pieces of lamp plates, 92 top respectively.Magnet is in original state far from lamp plate at this time, such as Fig. 2 institutes
Show.Turning knob makes drive shaft rotate (shaft does not move linearly), since shaft is connect with magnet external threading, so that
Magnet set moves straight down, limits magnet set rotation due to being provided with pin 313 on the side wall of magnet set, ensure that magnet
Set can only move down, so that magnet set and magnet move down until magnet 32 and that block lamp plate 91 to be safeguarded are inhaled
It closes (magnetic iron plate is provided in lamp plate), as shown in Figure 3.Further, by operating eccentric handle 6 so that two guide rods 5 to
Upper movement so that lamp plate 91 is detached with lamp box 90, as shown in Figure 4.Then, negative direction turning knob is only needed so that magnet is raised to
The separation of magnet and lamp plate can be realized in original state.It can be seen that maintenance tool before LED display provided by the utility model
It is easy to operate, and in lamp plate and lamp box separation process, the power that lamp plate is received is perpendicular to lamp plate (that is, the direction of motion with lamp plate
It is parallel), it is damaged due to loading angle is improper so as to avoid lamp plate.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model
