DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] The utility model provides two technical schemes:

[0025] Figures 1-5 The first embodiment is shown: a kind of electromagnetic alarm easy to assemble, including electromagnetic alarm assembly body 1, electromagnetic alarm assembly body 1 includes: pole shoe assembly 2, pole shoe assembly 2 includes top plate 21, recess 22 is symmetrically opened at the edge of top plate 21 top surface in front and back two sides, and the opening of recess 22 faces outside, and L-shaped plugboard 26 is fixedly connected on the surface of top plate 21 in front and back two sides;Two coil assemblies 3, and two coil assemblies 3 are symmetrically assembled on pole shoe assembly 2, coil assembly 3 includes coil cylinder 31, and the top surface and bottom surface of coil cylinder 31 are fixedly connected with limit plate 33, one limit plate 33 top surface is symmetrically fixedly connected with hook buckle 34, and hook buckle 34 can be buckled in recess 22.

[0026] Specifically, the top plate 21 of pole shoe assembly 2 as basic bearing part, the recess 22 on its top surface cooperates with the hook buckle 34 on the limit plate 33 of coil assembly 3, when assembling, hook buckle 34 is buckled into recess 22 to realize the rapid positioning and preliminary fixation of coil assembly 3 on pole shoe assembly 2, ensure the accuracy of the installation position of coil assembly 3, prevent its displacement in horizontal direction, and L-shaped plugboard 26 provides plug-in mounting structure for coil cylinder 31, so that coil assembly 3 can be conveniently connected with pole shoe assembly 2 from side, this structure design changes traditional complex fixing mode, and simplifies assembly process.

[0027] In the embodiment, the left and right side surfaces of top plate 21 are fixedly connected with side plate 23, and the opposite side surfaces of the two side plates 23 are fixedly connected with foot 24, and the mounting hole 25 is penetrated and arranged on the foot 24.

[0028] Specifically, side plate 23 enhances the overall structural strength of pole shoe assembly 2, so that it is more stable and not easy to deform during assembly and use, foot 24 and the mounting hole 25 thereon provide a convenient mounting mode for the electromagnetic alarm, and the entire electromagnetic alarm assembly body 1 can be firmly installed at the predetermined position by passing the fixing member such as screw through the mounting hole 25.

[0029] In this embodiment, the two side surfaces of the L-shaped plug plate 26 are provided with concave surfaces 27, and a plurality of elastic pieces 28 are arranged on the surfaces of the concave surfaces 27, and the knock-up portions of the elastic pieces 28 are directed towards the direction of the foot 24.

[0030] Specifically, when the coil cylinder 31 is inserted into the L-shaped plug plate 26 through the rectangular hole 32, the elastic pieces 28 on the concave surface 27 are in close contact with the inner wall of the rectangular hole 32, and during the insertion process, the elastic pieces 28 are extruded to deform, and the knock-up portions are clamped on the inner wall of the rectangular hole 32, further enhancing the stability of the connection between the coil assembly 3 and the pole shoe assembly 2, effectively preventing the coil cylinder 31 from loosening or falling off in the vertical direction.

[0031] In this embodiment, the top of the hook 34 is provided with an inclined surface 35.

[0032] Specifically, through the design of the inclined surface 35, when the coil assembly 3 is continuously pushed forward, the top plate 21 will generate an oblique extrusion force on the hook 34, so that the hook 34 can be deformed and bent along the inclined surface 35, thereby more easily sliding into the groove 22 on the top surface of the top plate 21.

[0033] In this embodiment, the rectangular hole 32 is provided in the inside of the coil cylinder 31, and the rectangular hole 32 has an up-down through structure, through which the coil cylinder 31 can be inserted into the L-shaped plug plate 26, and the inner wall of the rectangular hole 32 can be in close contact with the elastic pieces 28.

[0034] Specifically, the up-down through structure of the rectangular hole 32 provides precise guidance and matching space for the connection between the coil cylinder 31 and the L-shaped plug plate 26.

[0035] In this embodiment, the coil cylinder 31 is wound with a wire 36 outside.

[0036] Figure 1 The second embodiment is shown, and the main difference from the first embodiment is that when the pole shoe and the coil of the traditional electromagnetic alarm assembly are assembled, an electric soldering iron is needed to melt the fixing buckle on the coil seat, and after waiting for the coil fixing buckle to be flattened, the coil and the pole shoe are fixed. Such an installation method needs a special "melting fixing buckle" process, and the efficiency is not high.

[0037] Meanwhile, the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0038] First, two coil assemblies 3 are assembled with the pole shoe assembly 2 respectively, and during the assembly, the coil cylinder 31 is inserted into the L-shaped plug plate 26 of the pole shoe assembly 2 through the rectangular hole 32 in the inside of the coil cylinder 31, and because the inner wall of the rectangular hole 32 is in close contact with the elastic pieces 28, the elastic pieces 28 will deform during the insertion process, and the coil cylinder 31 is clamped and fixed.

[0039] Meanwhile, the hook 34 on the limiting plate 33 of the coil assembly 3 has a top with an inclined surface 35, which, during the insertion process, contacts the side of the top plate 21 and exerts a pressing force on the hook 34 to make it deform and bend until the hook 34 enters the groove 22 and restores its deformation, thereby being buckled in the groove 22 and further stabilizing the connection between the coil assembly 3 and the pole shoe assembly 2.

[0040] This assembly method does not need to melt the coil fixing buckle with an electric iron as in the traditional method, greatly simplifies the assembly process, reduces the special "buckling fixing" process, effectively improves the assembly efficiency, reduces the assembly cost, and the assembly connection is stable and reliable, which is conducive to improving the production efficiency and product quality of the electromagnetic alarm.
