Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] When the electromagnetic vibrator is powered on, the up and down movement of the vibrating rod generates friction with the frame, causing the electromagnetic coil to move on the frame, which can easily cause the electromagnetic coil to loosen upwards, causing offset or increased operating current, thereby affecting the normal operating efficiency of the dust collector.

[0030] Currently, existing electromagnetic rappers typically use a sealant to bond the electromagnetic coil to the frame inside the housing, securing the coil to the frame. The electromagnetic coil is connected to a junction box, and power is applied to activate the rapping rod. However, this mounting method makes it difficult to remove the electromagnetic coil when the electromagnetic rapper needs to be repaired, and can easily damage the coil and frame, rendering them unusable.

[0031] In order to facilitate installation and disassembly of the electromagnetic coil, the utility model proposes an electromagnetic rapper.

[0032] The electromagnetic rapper provided by the utility model is now described.

[0033] refer to Figure 1 , an electromagnetic rapper, including a shell 1, a skeleton 2, an electromagnetic coil 3, a junction box 4 and a rapping rod 5, the skeleton 2 is arranged inside the shell 1, the electromagnetic coil 3 is sleeved on the skeleton 2, the junction box 4 is arranged on the shell 1, and the junction box 4 is connected to the electromagnetic coil 3, the rapping rod 5 is arranged inside the skeleton 2, the rapping rod 5 can move back and forth up and down along the axial direction of the skeleton 2 and can pass through the shell 1 during movement, the electromagnetic rapper also includes two fixed structures 6 that can be elastically telescopically deformed, the two fixed structures 6 are both sleeved on the skeleton 2, and respectively abut against the top and bottom of the electromagnetic coil 3.

[0034] In this embodiment, the fixed structure 6 that can elastically expand and contract means that the fixed structure 6 can stretch and contract through elastic action, that is, the fixed structure 6 can be in an expanded and shrunk state, so that the fixed structure 6 can be stably mounted on the skeleton 2, and the two fixed structures 6 are respectively abutted against the top and bottom of the electromagnetic coil 3, that is, the two fixed structures 6 can limit the electromagnetic coil 3 so that the electromagnetic coil 3 will not be displaced on the skeleton 2.

[0035] When installing the electromagnetic rapper in the above embodiment, the fixing structure 6 is stretched to allow the frame 2 to be inserted, and the two fixing structures 6 are moved to the top and bottom positions of the electromagnetic coil 3 respectively and loosened. Under the elastic deformation of the fixing structure 6, the fixing structure 6 is firmly fixed to the frame 2, thereby limiting the range of movement of the electromagnetic coil 3 and fixing the electromagnetic coil 3. When disassembling, the electromagnetic coil 3 can be removed from the frame 2 by stretching and moving the fixing structure 6 to separate it from the frame 2, which is convenient for the operator to operate and will not cause damage to the electromagnetic coil 3 and the frame 2.

[0036] refer to Figures 1 to 4 As an optional embodiment, the fixing structure 6 includes a first fixing ring 60, a second fixing ring 61 and two connecting structures 62; the first fixing ring 60 and the second fixing ring 61 are symmetrically arranged; one symmetrical end of the first fixing ring 60 and the second fixing ring 61 is slidably and elastically connected to one of the connecting structures 62, and the other symmetrical ends of the first fixing ring 60 and the second fixing ring 61 are slidably and elastically connected to the other connecting structure 62.

[0037] Specifically, when the fixing structure 6 needs to be installed on the skeleton 2, the first fixing ring 60 and the second fixing ring 61 are pulled in opposite directions under the sliding connection between the first fixing ring 60 and the second fixing ring 61 and the connecting structure 62, so that the distance between the first fixing ring 60 and the second fixing ring 61 increases. At this time, the fixing structure 6 is in an extended (i.e., expanded) state, and then the skeleton 2 is put between the first fixing ring 60 and the second fixing ring 61, and the fixing structure 6 is moved to the specified position synchronously as a whole, and then the first fixing ring 60 and the second fixing ring 61 are released. Under the elastic connection between the first fixing ring 60 and the second fixing ring 61 and the connecting structure 62, the first fixing ring 60 and the second fixing ring 61 move in opposite directions through the elastic restoring force and are clamped with the skeleton 2. That is, at this time, the fixing structure 6 is stably put on the skeleton 2. Similarly, when it is necessary to remove the fixing structure 6 from the skeleton 2 and disassemble the electromagnetic coil 3, it is only necessary to pull the first fixing ring 60 and the second fixing ring 61 in opposite directions so that the distance between the first fixing ring 60 and the second fixing ring 61 increases, and the fixing structure 6 is in an extended (i.e., expanded) state, and then move the fixing structure 6 to separate from the skeleton 2.

[0038] When fixing and installing the electromagnetic coil 3, first fix the fixing structure 6 at the top of the electromagnetic coil 3 to the frame 2, then wind the electromagnetic coil 3 around the frame 2, and finally fix the fixing structure 6 at the bottom of the electromagnetic coil 3 to the frame 2. If only the electromagnetic coil 3 needs to be disassembled, just remove the fixing structure 6 at the bottom of the electromagnetic coil 3 from the frame 2, and then remove the electromagnetic coil 3.

[0039] refer to Figures 2 to 4As an optional embodiment, the connecting structure 62 includes a connecting rod 621, a stopper 622, a first connecting block 623, a second connecting block 624 and an elastic structure 625; the number of the stoppers 622 is two and they are respectively arranged at both ends of the connecting rod 621; the first connecting block 623 and the second connecting block 624 are both slidably mounted on the connecting rod 621, the first connecting block 623 is connected to one end of the first fixing ring 60, and the second connecting block 624 is connected to one end of the second fixing ring 61; the elastic structure 625 is mounted on the connecting rod 621, and the two ends of the elastic structure 625 are respectively connected to the first connecting block 623 and the second connecting block 624.

[0040] When the fixing structure 6 is extended, the first fixing ring 60 and the second fixing ring 61 are pulled in opposite directions. At this time, the first connecting block 623 and the second connecting block 624 on the two connecting rods 621 slide in opposite directions along the length direction of the connecting rod 621, and stretch the elastic structure 625. When the skeleton 2 is inserted and the fixing structure 6 is moved to the specified position, the first fixing ring 60 and the second fixing ring 61 are released. Under the elastic restoring force of the elastic structure 625, the first connecting block 623 and the second connecting block 624 slide in opposite directions along the length direction of their respective connecting rods 621 until the first fixing ring 60 and the second fixing ring 61 are clamped to the skeleton 2.

[0041] Since the first connecting block 623, the second connecting block 624 and the elastic structure 625 can slide along the connecting rod 621, after the elastic structure 625 contracts, the first fixing ring 60 and the second fixing ring 61 may be located at one end of the connecting rod 621 due to uneven force, thereby affecting the overall stability of the fixing structure 6. Figures 2 to 4 Optionally, the elastic structure 625 includes a first elastic member 6251, a second elastic member 6252 and a fixed block 6253; the fixed block 6253 is sleeved on the connecting rod 621 and is located between the first elastic member 6251 and the second elastic member 6252; one end of the first elastic member 6251 is connected to the first connecting block 623, and the other end is connected to the fixed block 6253; one end of the second elastic member 6252 is connected to the second connecting block 624, and the other end is connected to the fixed block 6253. Among them, the fixing block 6253 is used to fix one end of the first elastic member 6251 and the second elastic member 6252. When the first fixing ring 60 and the second fixing ring 61 are pulled, the first elastic member 6251 and the second elastic member 6252 can be stretched synchronously, so that after the first elastic member 6251 and the second elastic member 6252 are contracted, the first fixing ring 60 and the second fixing ring 61 can be located in the middle of the connecting rod 621, that is, they are symmetrical relative to the middle position of the connecting rod 621, so that the various components of the fixed structure 6 are evenly stressed, thereby improving the stability of the fixed structure 6.

[0042] Because the specifications of electromagnetic rappers used at different construction sites may vary, the fixing structure 6 needs to be adaptable to the different specifications of the frame 2 in order to secure the electromagnetic coil 3 of electromagnetic rappers of different specifications. Optionally, the first fixing ring 60 and the second fixing ring 61 are both detachably connected to the connecting structure 62. When the fixing structure 6 needs to be used for an electromagnetic rapper of a different specification, the first fixing ring 60 and the second fixing ring 61 of the fixing structure 6 can be disassembled and replaced with the first fixing ring 60 and the second fixing ring 61 of the different specification.

[0043] refer to Figures 2 to 5 As an optional embodiment, a first extension portion 63 is extended from the first connecting block 623 on one side of the first fixing ring 60 and from the second connecting block 624 on one side of the second fixing ring 61, and a second extension portion 64 is extended from both ends of the first fixing ring 60 and the second fixing ring 61, and each first extension portion 63 is detachably connected to the adjacent second extension portion 64 by a fixing member 65.

[0044] Specifically, when installing the first fixing ring 60 and the second fixing ring 61, each first extension portion 63 is connected to the adjacent second extension portion 64 via the fixing member 65. Similarly, when disassembling the first fixing ring 60 and the second fixing ring 61, it is only necessary to remove the fixing member 65 to separate the first extension portion 63 and the second extension portion 64.

[0045] In order to make the structure simple and easy to operate, refer to Figure 5 Optionally, a first threaded hole 631 is provided on the first extension portion 63, a second threaded hole (not shown in the figure) matching the first threaded hole 631 is provided on the second extension portion 64, and the fixing member 65 adopts a bolt assembly.

[0046] refer to Figure 1 As an optional embodiment, the housing 1 includes a top cover 10, a shell 11, a bottom plate 12 and a bottom sleeve 13; the top cover 10 is arranged on the top of the shell 11, the bottom sleeve 13 is arranged on the bottom plate 12 and the inner diameter of the bottom sleeve 13 matches the outer diameter of the frame 2, the bottom plate 12 is connected to the shell 11 through a flange, and an opening is opened on the bottom plate 12 for the rapping rod 5 to pass through.

[0047] The installation process of the electromagnetic rapper is as follows: first, the top cover 10 is placed on the top of the shell 11, and then one of the fixing structures 6 is fixed on the upper part of the skeleton 2, the electromagnetic coil 3 is placed on the skeleton 2, the skeleton 2 is placed in the shell 11, and the electromagnetic coil 3 is connected to the junction box 4, and then the other fixing structure 6 is fixed on the lower part of the skeleton 2, and the bottom plate 12 is docked with the shell 11 so that the bottom end of the skeleton 2 is inserted into the bottom sleeve 13 and fits tightly with the bottom sleeve 13, and the bottom plate 12 is fixed to the shell 11 by bolts and nuts, and finally the rapping rod 5 is placed in the skeleton 2. Through the cooperation of various components, the overall structure is safe and stable.

[0048] In order to play a buffering role on the rapping rod 5, it is prevented from generating a large impact force with the top cover 10 when the rapping rod 5 moves up and down in the frame 2. Figure 1 Optionally, a buffer structure 14 is provided on the side of the top cover 10 facing the shell 11 .

[0049] Based on considerations of structural complexity and cost, the buffer structure 14 may optionally be a rubber pad.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
