DETAILED DESCRIPTION
[0024] Reference Figure 1 As shown, the long and deep hole one-piece injection molded shell includes an injection molded shell 1 spliced by a first shell 11 and a second shell 12, the first connecting blocks 13 are fixed on the left and right sides of the outer surface of the first shell 11, and the third connecting block 15 is fixed in the middle, while the second connecting blocks 14 are fixed on the left and right sides of the outer surface of the second shell 12, and the fourth connecting block 16 is fixed in the middle, the first connecting block 13 corresponds to the second connecting block 14, and the third connecting block 15 is aligned with the fourth connecting block 16.
[0025] For example, Figure 2 As shown, in order to avoid an unstable connection between the first shell 11 and the second shell 12 after docking, the opposite surfaces of the first connecting block 13 and the second connecting block 14 are provided with plug-in blocks 17 and sockets 6 that can be plugged into each other, while the third connecting block 15 is provided with the socket 6, and the plug-in block 17 is fixed on the fourth connecting block 16. The plug-in block 17 and the socket 6 form a buckle structure to ensure the stability of the first shell 11 and the second shell 12 after docking.
[0026] Exemplarily, to facilitate the separation of the first shell 11 and the second shell 12, both ends of the socket 6 are connected to the outside, so that after the plug 17 is inserted into the socket 6, the user can use an external rod or fingers to resist the insertion end of the plug 17 to make the extended part of the plug 17 re-enter the socket 6, thereby facilitating the separation of the first shell 11 and the second shell 12.
[0027] For example, Figure 4 In order to facilitate the installation of the control board and the coil, the first shell 11 and the second shell 12 are fixed with a longitudinal first protrusion 18 and a transverse second protrusion 19 corresponding to the vertical state of the injection molded shell 1. The first protrusion 18 contains multiple protrusions and the spacing between each protrusion corresponds to the size of the control board. The first protrusion 18 is separated by the second protrusion 19 and is divided into two parts, the upper part is called the first placement groove 21, and the lower part is called the second placement groove 22. The control board can be placed in the first placement groove 21, and the coil can be placed in the second placement groove 22.
[0028] Exemplarily, although the first raised portion 18 isolates and the second raised portion 19 isolates a plurality of accommodating spaces, not all accommodating spaces are the first placement groove 21 and the second placement groove 22. To distinguish them, the second limiting member 4 is fixed at the connection between the two first placement grooves 21, and the first limiting member 3 is fixed in the middle of the second placement groove 22, so as to facilitate users to align the control board and the coil with the first placement groove 21 and the second placement groove 22.
[0029] Exemplarily, in order to enable the first limit member 3 and the second limit member 4 to limit the control board and the coil respectively, it is possible to avoid the use of gluing or screwing to fix the control board and the coil, which makes the replacement of the control board and the coil more cumbersome. In addition, the gluing or screwing method still requires squeezing the control board and the coil with force, which indirectly squeezes the inner cavity of the injection molded shell 1 and may cause deformation of the inner wall of the injection molded shell 1.
[0030] Exemplarily, the first limit member 3 is divided into a first outer limit plate 31 and a first inner limit plate 32, the first inner limit plate 32 is fixed on the injection molding shell 1, and the second limit member 4 is divided into a second outer limit plate 41 and a second inner limit plate 42, the second inner limit plate 42 is fixed on the injection molding shell 1, the first inner limit plate 32 and the second inner limit plate 42 are provided with a connecting component 5, wherein a slide groove 51 is opened on the outer surface of the first inner limit plate 32 and the second inner limit plate 42, and a slider 52 is slidably connected in the slide groove 51, and the sliders 52 in the first inner limit plate 32 and the second inner limit plate 42 are respectively fixed to the inner surfaces of the first outer limit plate 31 and the second outer limit plate 41, so that the first outer limit plate 31 and the second outer limit plate 41 can block the control plate in the first placement groove 21 and the coil in the second placement groove 22 by moving.
[0031] For example, Figure 5 As shown, the first outer limit plate 31 and the second outer limit plate 41 can effectively block and limit the control board and the coil after moving. An extension opening 53 is opened on one side wall of the slide groove 51 and extends to the outside. An extension rod 54 is inserted into the extension opening 53. As the extrusion direction changes, one end of the extension rod 54 is always located inside or outside the slide groove 51. At this time, after the first outer limit plate 31 and the second outer limit plate 41 are moved out to block the control board and the coil, the other end of the extension rod 54 is pushed to the outside so that the other end of the extension rod 54 enters the slide groove 51 to contact the side wall of the slider 52, so that the first outer limit plate 31 and the second outer limit plate 41 can stably block and limit the control board and the coil.
[0032] Exemplarily, the side wall of the slider 52 is provided with a limiting opening 58 which can be plugged into the extension rod 54, so that the first outer limiting plate 31 and the first inner limiting plate 32 as well as the second outer limiting plate 41 and the second inner limiting plate 42 will not separate easily when they are overlapped.
[0033] Exemplarily, an opening 55 is provided on one side of the extension rod 54 located in the extension opening 53, and a protrusion 56 is fixed on the upper end face of the opening 55. The bottom of the protrusion 56 is V-shaped and the top is also V-shaped, and a movable groove 59 with the same shape as the protrusion is provided on the surface. One end of the limit rod 57 is connected to the movable groove 59, and the other end of the limit rod 57 is fixed to the inner wall of the extension opening 53 to form a spring buckle structure. When the user presses the extension rod 54 once, the inner wall of the movable groove 59 squeezes the limit rod 57, so that the end of the limit rod 57 located in the movable groove 59 moves from the lower part of the movable groove 59 to the upper part, and forms a snap connection with the bottom of the V-mouth at the upper part of the movable groove 59. At this time, one end of the extension rod 54 protrudes from the slide groove 51 to contact the side wall of the slider 52, and then is plugged into the upper limit opening 58 of the slider 52.
[0034] Exemplarily, when the user presses the extension rod 54 for the second time, the limiting rod 57 in the moving groove 59 moves from the upper part to the lower part, so that one end of the extension rod 54 protrudes outside.
[0035] At this point, the first shell 11 and the second shell 12 can be connected to form an injection molded shell 1 by connecting the first connecting block 13 and the second connecting block 14 and the third connecting block 15 and the fourth connecting block 16. The main connection method is the plug-in connection between the plug block 17 and the socket 6, and the principle is consistent with the buckle structure principle.
[0036] The first and second shell bodies 11 and 12 further have first and second protrusions 18 and 19 fixed on their surfaces, and the first and second protrusions 18 and 19 form a first placement groove 21 and a second placement groove 22, in which the control board and the coil can be placed respectively.
[0037] A second limiting member 4 and a first limiting member 3 are respectively provided in the first placement groove 21 and the second placement groove 22. The second limiting member 4 and the first limiting member 3 include a second outer limiting plate 41 and a second inner limiting plate 42 as well as a first outer limiting plate 31 and a first inner limiting plate 32. The second outer limiting plate 41 and the first outer limiting plate 31 can respectively shield the coil and the control board to prevent the coil and the control board from being bonded to the second placement groove 22 and the first placement groove 21 or fixed with screws.
[0038] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
