[0021] As Figure 1 The utility model discloses a hoisting structure of line array loudspeaker, including hoisting piece 1, the top of hoisting piece 1 is set up and has received groove 11, the received groove 11 is embedded with the elastic hanger arm 2 of the hoisting end 21 that can automatically pop up upwards, the side wall of hoisting piece 1 is inserted with the positioning pin 3, and positioning pin 3 can be inserted on elastic hanger arm 2 to prevent the hoisting end 21 of elastic hanger arm 2 from popping up to the outside of received groove 11, and positioning pin 3 can be separated from elastic hanger arm 2 by pulling, and when positioning pin 3 separates from elastic hanger arm 2, the hoisting end 21 of elastic hanger arm 2 can automatically pop up to the outside of received groove 11.

[0022] On the hoisting structure of this line array loudspeaker, the hoisting piece 1 is used for fixedly setting on the side of line array loudspeaker, in order to provide reliable hoisting position.

[0023] By embedding the elastic hanging arm 2 capable of automatically upwardly popping out the hoisting end 21 in the receiving groove 11, this can make the hoisting end 21 always be in the protruding position when splicing the line array speaker through the hoisting mode, so that only one splicing personnel needs to swing the upper line array speaker to make the hoisting hole slot thereon align with the hoisting end 21, and then lower the upper line array speaker, which can accurately restrict the two line array speakers together by the cooperation of the hoisting end 21 and the corresponding hoisting hole slot, and finally insert the corresponding plug pin, so as to quickly realize the splicing of the line array speaker. Therefore, it not only can facilitate the operation of one splicing personnel, but also can make the splicing process very simple, which can help to reduce the splicing cost, improve the splicing convenience and improve the splicing efficiency.

[0024] The positioning plug pin 3 is inserted on the side wall of the hoisting piece 1, and the positioning plug pin 3 can be inserted on the elastic hanging arm 2 to prevent the hoisting end 21 of the elastic hanging arm 2 from being popped out to the outside of the receiving groove 11, and the positioning plug pin 3 can be pulled away from the elastic hanging arm 2. This not only can store and manage the elastic hanging arm 2 when the elastic hanging arm 2 is not needed, but also can quickly pop out the hoisting end 21 of the elastic hanging arm 2 to the outside of the receiving groove 11 by pulling, which can make the hoisting structure have a very reliable and convenient to use structure.

[0025] Therefore, the hoisting structure can have very high reliability and applicability.

[0026] As shown in Figure 1 The first elastic member 12 is arranged on the hoisting piece 1, and the first elastic member 12 elastically acts on the positioning plug pin 3, and the positioning plug pin 3 can be automatically inserted on the elastic hanging arm 2 under the elastic action of the first elastic member 12. In this way, the first elastic member 12 can make the positioning plug pin 3 more stably inserted on the elastic hanging arm 2, so as to help to more stably and reliably position the elastic hanging arm 2, and further help to further improve the reliability and applicability of the hoisting structure.

[0027] As shown in Figure 1As shown in actual manufacturing process, the first elastic member 12 can be assembled in the following structure: the first elastic member 12 can be a coil spring, the lifting member 1 is provided with a positioning tube 10 communicated with the receiving groove 11, the positioning plug 3 is movably arranged in the positioning tube 10, the first elastic member 12 is sleeved on the positioning plug 3 in the positioning tube 10, and the two ends of the first elastic member 12 are elastically applied to the positioning tube 10 and the positioning plug 3 respectively, and the first elastic member 12 pushes the positioning plug 3 to move towards the receiving groove 11 by elastic force, the outer end of the positioning plug 3 is provided with a sleeving tube 20, and the sleeving tube 20 is slidably sleeved on the positioning tube 10. Thus, the first elastic member 12 can stably exert the elastic force, so that the positioning plug 3 can stably play the positioning role. The above only introduces one assembly structure of the first elastic member 12 and the positioning plug 3, which is not a limitation on the assembly structure of the first elastic member 12 and the positioning plug 3, and other assembly structures without departing from the concept of the present application also belong to the protection scope of the present application.

[0028] As shown in Figure 1 , the lifting end 21 is provided with a lifting hole 211, and the positioning plug 3 is inserted into the lifting hole 211 to prevent the lifting end 21 from being popped out upwardly to the outside of the receiving groove 11. Thus, it is not necessary to provide other slot positions for the positioning plug 3 on the elastic lifting arm 2 to limit the pop-out of the lifting end 21, which not only reduces the manufacturing difficulty, but also makes the positioning role of the positioning plug 3 to the elastic lifting arm 2 very stable and reliable.

[0029] As shown in Figure 1 , the outer end of the positioning plug 3 is provided with a first ring groove 31 on the circumferential surface. The first ring groove 31 can facilitate the action of the fingers, thereby avoiding the slipping condition, and further improving the convenience of pulling the positioning plug 3.

[0030] As shown in Figure 1 , the bottom surface of the lifting member 1 is provided with a lifting groove 13 for inserting the lifting end, and the sidewall of the lifting member 1 is provided with a lifting plug 4 which can be inserted into the lifting end inserted into the lifting groove 13. Thus, the lifting member 1 can be connected in a head-to-tail structure, which not only facilitates the installation and positioning of the lifting structure, but also ensures that the lifting structure has higher reliability and stability, thereby further improving the reliability and applicability of the lifting structure.

[0031] As shown in Figure 1 and Figure 2 , the lifting member 1 is a tubular lifting member, and the two ends of the lifting member 1 form the receiving groove 11 and the lifting groove 13 respectively. This not only reduces the manufacturing difficulty of the lifting member 1, but also facilitates the better matching of the lifting member 1 with the structure of the line array loudspeaker, thereby further improving the applicability of the lifting structure.

[0032] As shown in Figure 1 , the inner end of the positioning pin 3 is inserted through the receiving groove 11; this can make the positioning effect of the positioning pin 3 on the elastic hanging arm 2 more stable and reliable. The inner end of the hoisting pin 4 is inserted through the hoisting groove 13; this can realize more stable and reliable hoisting effect.

[0033] As shown in Figures 1 to 3 , the side wall of the hoisting piece 1 is provided with a fixed sheet strip 14. The hoisting piece 1 is installed on the side wall of the linear array loudspeaker in an embedded manner, the fixed sheet strip 14 is overlapped on the linear array loudspeaker and is fixed by using a screw 141, so that the convenience and stability of the installation and positioning of the hoisting structure can be improved.

[0034] As shown in Figure 1 , the hoisting piece 1 is provided with a second elastic member 15, and the second elastic member 15 elastically acts on the hoisting pin 4, and the hoisting pin 4 can be automatically inserted and mounted in the hoisting hole 211 under the elastic action of the second elastic member 15. This can stably insert and mount the hoisting pin 4 on the hoisting end 21 during hoisting, thereby helping to improve the stability and reliability of hoisting.

[0035] As shown in Figure 1 , in actual manufacturing process, the assembly structure of the second elastic member 15 and the hoisting pin 4 can adopt the same assembly structure as the assembly of the first elastic member 12 and the positioning pin 3, that is, the second elastic member 15 is composed of a helical spring, and the hoisting pin is guided and limited by the cooperation of the positioning tube and the sleeving tube, so that the assembly of the second elastic member 15 and the hoisting pin 4 can meet the needs of actual production and use. Of course, this is only one assembly structure of the second elastic member 15 and the hoisting pin 4, and is not a limitation on the assembly structure of the second elastic member 15 and the hoisting pin 4, and other assembly structures without departing from the concept of the present application also belong to the protection scope of the present application.

[0036] As shown in Figure 1 and Figure 2 , a second ring groove 41 is formed on the circumferential surface of the outer end of the hoisting pin 4. The second ring groove 41 can facilitate the action of the fingers, thereby avoiding the occurrence of slipping, and thereby facilitating the convenience of pulling the hoisting pin 4.

[0037] As shown in Figure 1 and Figure 2As shown, the slot wall of the receiving groove 11 is provided with a limiting guide groove 111, the elastic hanging arm 2 is provided with a limiting protrusion 22, and the limiting protrusion 22 is slidingly embedded in the limiting guide groove 111. The groove bottom of the receiving groove 11 is provided with an elastic pushing piece 5, and the elastic pushing piece 5 is elastically pressed on the inner end face of the elastic hanging arm 2. In this way, the positioning of the elastic hanging arm 2 can be accurately and stably realized, so that the stable and reliable hoisting effect of the elastic hanging arm 2 can be improved, and the reliability and applicability of the hoisting structure can be further improved.

[0038] The elastic pushing piece 5 is a spiral spring. The above only introduces the installation and positioning of the elastic hanging arm 2 and the structure for obtaining elastic force, and is not a limitation on the installation structure of the elastic hanging arm 2. Other assembly structures that do not deviate from the concept of the present application also belong to the protection scope of the present application. For example, a waist-shaped hole can also be formed in the elastic hanging arm 2, and a limiting pin arranged through the waist-shaped hole can be arranged on the hoisting piece 1, so that the limiting is realized by the cooperation of the limiting protrusion 22 and the limiting guide groove 111.

[0039] As shown in Figure 3 In actual use, two hoisting structures are arranged on the left and right ends of the line array loudspeaker. When assembling the line array loudspeaker, first hoist one line array loudspeaker; then move another line array loudspeaker to the lower side of the hoisted line array loudspeaker; then pull the positioning pin 3 to make the hoisting end 21 of the elastic hanging arm 2 pop out of the receiving groove 11; then pull the two hoisting pins 4 with both hands to make them away from the corresponding hoisting holes 211, and swing the hoisted line array loudspeaker to make the two hoisting holes 211 on the line array loudspeaker face the corresponding hoisting ends 21, and slowly lower to make the two hoisting holes 211 respectively fit on the corresponding hoisting ends 21; finally, release the hoisting pin 4, which can make the hoisting pin 4 fit in the corresponding hoisting hole 211. In this way, a splicing person can also realize the splicing of the line array loudspeaker, so as to reduce the splicing cost, improve the splicing convenience and efficiency.
