DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-4 An assembled broadband horn antenna shown in the figure comprises a terminal block 1, a horn housing 2 is provided on one side of the terminal block 1, the horn housing 2 is slidably engaged with the terminal block 1 in a vertical direction, a fixing frame 5 is fixedly connected to the inner wall of the horn housing 2, a clamping piece 4 is fixedly connected to one side of the terminal block 1, the outer wall of the clamping piece 4 is slidably engaged with the fixing frame 5, the cross section of the clamping piece 4 is L-shaped, the fixing frame 5 is slidably sleeved on the vertical part of the clamping piece 4, so that the fixing frame 5 and the clamping piece 4 are slidably engaged, and the distance between the terminal block 1 and the horn housing 2 can be limited to keep a stable engaged state, and by sliding the horn housing 2 vertically upward relative to the terminal block 1, the horn housing 2 can drive the fixing frame 5 to separate from the clamping piece 4, and the number of the clamping pieces 4 on one side of the terminal block 1 is four, and the number of the fixing frames 5 inside the horn housing 2 is also four, thereby ensuring that the horn housing 2 is clamped on one side of the terminal block 1 for stability. A limit assembly 3 for clamping and locking the speaker housing 2 at a vertical height is provided on the side of the terminal block 1. The limit assembly 3 includes a first fixing plate 31, a second fixing plate 32 and a clamping plate 33. The first fixing plate 31 and the second fixing plate 32 are fixedly connected to the side of the terminal block 1 and the side of the speaker housing 2 respectively. The clamping plate 33 is slidably clamped between the first fixing plate 31 and the second fixing plate 32 in a horizontal state. Under the limitation of the clamping plate 33, the second fixing plate 32 cannot slide up and down relative to the first fixing plate 31. Therefore, under the action of the fixing frame 5 and the clamping member 4, the speaker housing 2 cannot move horizontally relative to the terminal block 1, so that the speaker housing 2 is stably installed on one side of the terminal block 1. The separation of the clamping plate 33 and the second fixing plate 32 can drive the fixing frame 5 to separate from the clamping member 4, thereby disassembling the speaker housing 2.

[0024] Specifically, a snap-in groove 34 is provided on one side of the second fixing plate 32, and one end of the outer wall of the snap-in plate 33 is slidably snap-fitted with the snap-in groove 34; a connecting groove 35 is provided on one side of the first fixing plate 31, and the other end of the outer wall of the snap-in plate 33 is slidably snap-fitted with the connecting groove 35; and there are two connecting grooves 35 provided on one side of the first fixing plate 31 and two snap-in grooves 34 provided on one side of the second fixing plate 32, and they correspond one to one, so that the two snap-in plates 33 are snap-fitted between the first fixing plate 31 and the second fixing plate 32, so that the speaker housing 2 can be snap-fitted and limited.

[0025] Furthermore, a through hole is provided on the top of the first fixing plate 31, and a connecting shaft 38 is rotatably sleeved in the inner cavity of the through hole, one end of the clamping plate 33 is fixedly installed on the outer wall of the connecting shaft 38, a knob 311 is fixedly connected to the top of the connecting shaft 38, and a fixing block 39 is fixedly connected to the end of the clamping plate 33. A mounting groove is provided on the outer wall of the connecting shaft 38, and the outer wall of the fixing block 39 is slidably sleeved with the mounting groove, so that the connecting shaft 38 is driven to rotate by the knob 311, so that the connecting shaft 38 can drive the two clamping plates 33 to clamp or separate with the second fixing plate 32, and the bottom of the connecting shaft 38 A fixing bolt 310 is inserted and sleeved through the threaded part, and a positioning hole is opened at the bottom of the fixing block 39. The outer wall of the fixing bolt 310 is slidably sleeved with the inner cavity of the positioning hole. The fixing bolt 310 can fix and limit the fixing block 39, so that the connecting shaft 38 and the clamping plate 33 form a whole, and the clamping plate 33 can also clamp and limit the connecting shaft 38 to ensure the stability of the connecting shaft 38 rotating in the through hole. By removing the fixing bolt 310, the connecting shaft 38 and the clamping plate 33 can be disassembled, thereby facilitating the installation or disassembly and maintenance of the connecting shaft 38 and the clamping plate 33.

[0026] Furthermore, a first magnet 36 is fixedly embedded on one side of the snap-in plate 33 facing the speaker housing 2, and a second magnet 37 is fixedly embedded on the inner wall of the snap-in groove 34. The first magnet 36 and the second magnet 37 have opposite magnetic poles facing each other. The magnetic attraction between the first magnet 36 and the second magnet 37 can limit the snap-in plate 33, thereby improving the stability of the snap-in plate 33 being snapped between the first fixing plate 31 and the second fixing plate 32. Rubber pads are fixedly connected to the top and bottom of the snap-in plate 33, and the rubber pads have a certain extrusion pressure against the inner wall of the snap-in groove 34, thereby improving the friction between the snap-in plate 33 and the inner wall of the snap-in groove 34 on the second fixing plate 32, thereby further increasing the stability of the snap-in plate 33 being snapped between the first fixing plate 31 and the second fixing plate 32.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
