The second clamping column 1134 is pulled out, the second end of the first fixed shaft 1132 is inserted from the first fixed hole 1123 and passes out from the adjusting opening 1112 at the corresponding position, wherein the length of the first clamping column 1133 is larger than the diameter of the first fixed hole 1123, or the diameter of the first sleeve 1131 is larger than the diameter of the first fixed hole 1123, so that the first end of the first fixed shaft 1132 is clamped outside the first fixed hole 1123.
As shown in fig. 5, fig. 5 is a bottom view of the arc-shaped lock assembly 11 shown in fig. 2, after the second end of the first fixing shaft 1132 passes through the adjusting opening 1112, the second clamping post 1134 is inserted into the second through hole on the second end of the first fixing shaft 1132 from the groove opening of the first locking block 111, and two ends of the second clamping post 1134 are located on the bottom of the inverted groove of the first locking block 111, so that the second clamping post 1134 spans across the adjusting opening 1112, thereby forming a clamping position. By twisting the first sleeve 1131 to rotate downwards, when the first sleeve 1131 rotates to the upper top end of the first clamping groove 1136 (i.e. the highest end point of the semi-spiral first clamping groove) to clamp with the first clamping post 1133, the first sleeve 1131 and the outer wall of the first fixing hole 1123 form a propping contact, meanwhile, the first fixing shaft 1132 is pulled upwards through the first clamping post 1133, and the first fixing shaft 1132 is kept in an upwards pulled state, so that the second clamping post 1134 is tightly attached to the bottom of the inverted groove of the first locking piece 111 to form a locking state, and the first locking piece 111 and the second locking piece 112 are fixed.
When the first locking piece 111 and the second locking piece 112 need to be separated, only the first sleeve 1131 needs to be turned reversely to rotate upwards, when the lower top end of the first clamping groove 1136 (i.e. the lowest end point of the semi-spiral first clamping groove) is clamped with the first clamping post 1133, the first sleeve 1131 is separated from the outer wall of the first fixing hole 1123, so that the first fixing shaft 1132 is in a loose state and slides downwards under the action of gravity, the second end of the first fixing shaft 1132 also slides downwards, the second clamping post 1134 is separated from the bottom of the inverted groove of the first locking piece 111, the second clamping post 1134 can be pulled out of the first fixing shaft 1132, then the first fixing shaft 1132 is sequentially pulled out of the adjusting opening 1112 and the first fixing hole 1123, and the first locking piece 111 and the second locking piece 112 can be separated.
In one embodiment, as shown in fig. 3 and 5, the first fixing member 113 may further include a spring 1137. After the first fixing shaft 1132 passes through the adjusting opening 1112, the spring 1137 is sleeved on the first fixing shaft 1132, and then the second clamping post 1134 passes through the second through hole of the first fixing shaft 1132, so that the spring 1137 is located between the second clamping post 1134 and the bottom of the inverted groove of the first locking piece 111. When the second clamping post is clamped on the bottom of the inverted groove of the first locking block 111, the spring 1137 is in a compressed state, and the second clamping post 1134 and the first locking block 111 can be fastened more under the action of the elastic force of the spring 1137. Moreover, when the first fixing shaft 1132 is in a released state, the second clamping post 1134 can be sprung away from the bottom of the inverted groove of the first locking piece 111 under the action of the elastic force of the spring 1137, so that the second clamping post 1134 can be pulled out of the first fixing shaft 1132 more conveniently.
In one embodiment, as shown in fig. 4 and 5, a plurality of second clamping grooves 1113 are further formed on the bottom of the inverted groove of the first locking block 111, and the second clamping grooves are sequentially arranged along the arc direction. When the second locking piece 112 slides to different positions, the first fixing hole 1123 corresponds to the second clamping groove 1113 at different positions, so that when the first fixing shaft 1132 is inserted from the first fixing hole 1123 and passes out from the adjusting opening 1112, the second clamping post 1134 is inserted into the first fixing shaft 1132, and when the second clamping post 1134 spans the adjusting opening 1112, two ends of the second clamping post 1134 are clamped in the second clamping groove 1113 at corresponding positions, thereby further improving the reliability of connection between the second clamping post 1134 and the first locking piece 111.
The fixing assembly 12 is connected with the second locking piece 112 through a second fixing hole 1124 on the connecting piece 1122 so as to connect the LED box a with the second locking piece 112, thereby realizing the splicing of the two LED boxes a and B.
In particular, referring to fig. 6 and 7 in combination with fig. 2 and 3, in one embodiment, the second securing aperture 1124 is an elongated aperture. The fixed assembly 12 includes a second sleeve 121, a spring clip 122, a cartridge 123, a second stationary shaft 124, and a housing 125.

The other end of the second fixing shaft 124 is a locking tongue 1241 extending out of the second sleeve 121, the locking tongue 1241 has the same shape as the second fixing hole 1124, and the length is smaller than the length of the second fixing hole 1124 but larger than the width of the second fixing hole 1124. The clamping seat 123 is fixed on the second sleeve 121, and the spring clip 122 is fixed on the clamping seat 123. One clamping plate 1221 of the spring clamp 122 is a free end, and the end of the other clamping plate 1222 is provided with a latch 20, and the latch 20 is clamped with the gear 30, so that the gear 30 is clamped by the abutting action of the clamping plate 1222, and the gear 30 is prevented from rotating.
When the gear 30 is required to rotate, the free end 1221 of the spring clip 122 is pressed by using the clamping seat 123 as a supporting point, so that the other clamping plate 1222 of the spring clip 122 is sprung up to separate from the gear 30, and at this time, the gear 30 can be rotated.
The inner wall of the housing 125 is also provided with a gear, and when the housing 125 is covered on the gear 30, the gear inside the housing 125 is engaged with the gear 30 on the second sleeve 121. The housing 125 has a handle, and the housing 125 is twisted by holding the handle of the housing 125, so that the gear 30 is twisted by the gear. Thus, the torsion gear 30 can be facilitated by the housing 125. When the fixing assembly 12 and the second locking block 112 need to be connected, the torsion gear 30 drives the second fixing shaft 124 to twist, so as to twist the latch 1241, so that the length direction of the latch 1241 is the same as the length direction of the second fixing hole 1124, and the latch 1241 can be inserted into the second fixing hole 1124. After the latch 1241 passes through the second fixing hole 1124, the latch 1241 is twisted by the twisting gear 30, so that the length direction of the latch 1241 is perpendicular to the length direction of the second fixing hole 1124, i.e. the length direction of the latch 1241 is the same as the width direction of the second fixing hole 1124, so that the latch 1241 and the connecting piece 1122 form a clamping connection, and the fixing assembly 12 and the second locking piece 112 are connected together.
In another embodiment, the second fixing shaft 124 of the fixing assembly 12 may also be a bolt, that is, the fixing assembly 12 may be fixedly connected with the second locking piece 112 by means of a bolt.
As shown in fig. 8, a third fixing hole a11 is provided on the LED box a to be spliced, and the latch 1241 of the fixing assembly 12 sequentially passes through the third fixing hole a11 and the second fixing hole 1124, thereby connecting the LED box a and the second locking piece 112.

Specifically, when the radian between the LED cases needs to be increased, the second locking piece 112 is slid to another LED case a to be spliced, and when the second locking piece slides to the required radian, the second locking piece 112 is connected with the LED case a by using the fixing component 12, and the first locking piece 111 is fixed with the second locking piece 112 by using the first fixing component 113, so that the splice between the LED cases is realized. The longer the second locking piece 112 slides towards the LED box a, the larger the radian between the LED boxes can be made, whereas the shorter the sliding distance of the second locking piece 112, the smaller the radian between the LED boxes is.
In one embodiment, further, as shown in fig. 2, the arc-shaped lock assembly 11 further includes a pulling post 114, and a plurality of clamping holes 1114 sequentially arranged along an arc direction are further provided on an outer surface of a side portion of the first locking piece 111, and the plurality of clamping holes 1114 are located under the arc-shaped sliding groove 1111. Wherein the shifting post 114 is mounted on the side of the arc 1121 and contacts the side of the first locking piece 111, the shifting post 114 is in a shifting state when the shifting post 114 slides between the two clamping holes 1114 as the second locking piece 112 slides along the arc chute 1111, the shifting post 114 is clamped into the clamping hole 1114 when sliding to the position of the clamping hole 1114, and is in a restoring state, wherein when the shifting post 114 slides from one clamping hole 1114 into the adjacent other clamping hole 1114, the second locking piece 112 slides by a predetermined arc, that is, when the second locking piece 112 slides by a distance between the adjacent two clamping holes 1114, the arc spliced between the LED housings changes by a predetermined arc, which may be set to 5 ° or 10 ° or the like, for example, without limitation.
When the dial column 114 returns to the reset state from the dial state, a "click" sound is generated, and it can be determined how many holes the dial column 114 passes through according to the sound, and then how much radian the second locking piece 112 slides can be determined, so that the radian of the splice between the LED boxes can be determined.
