Description

Technical Field

[0001] This utility model relates to the field of motor housing fixing technology, and in particular to a fixing structure for AC / DC motor housing. Background Technology

[0002] The casing of an AC / DC motor is the outer shell of the motor, used to fix the internal components of the motor, including the stator and rotor, and also serves to protect and dissipate heat. After the internal components of the motor are assembled, the casing and the housing need to be fixed together.

[0003] A utility model patent with patent authorization announcement number CN209344903U discloses a motor housing, belonging to the field of mechanical technology. The motor housing includes a barrel, with a through hole in the middle of the left end and an open right end. A lid is provided at the right end of the barrel, and the lid has an annular connecting part arranged coaxially with the connecting part. The connecting part is inserted into the right end of the barrel and is detachably fixed to the barrel via a threaded structure. An elongated rib is integrally formed on the inner wall of the barrel, extending along the axial direction of the barrel, with one end extending to the left end face of the barrel. There are at least two ribs, evenly spaced along the circumference of the barrel. Each rib has a threaded hole penetrating along the axial direction of the barrel. An insertion hole is provided on the connecting part, with the number of insertion holes and threaded holes being the same and their positions corresponding one-to-one. A screw is screwed into each threaded hole, with the right end of the screw extending out of the threaded hole and inserted into the corresponding insertion hole. The casing of this electric motor is quite aesthetically pleasing.

[0004] However, the existing fixing structure of AC / DC motor housing also has certain shortcomings. Although the existing fixing structure of AC / DC motor housing uses bolts to lock the housing cover and housing together, due to factors such as vibration, long-term use will cause the bolts to become loose. Moreover, the bolts are mostly exposed after installation and fixing, and due to the influence of external water bodies, the bolts are prone to corrosion, which weakens the bolt structure strength. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixing structure for the housing of an AC / DC motor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fixing structure for an AC / DC motor housing includes a housing, a housing cover in contact with the front of the housing, a protective mesh fixedly connected inside the housing cover, two symmetrically distributed support seats fixedly connected to the lower side of the housing, a plurality of heat dissipation grooves arranged in a ring array on the surface of the housing, and a fixing mechanism provided on the housing cover.

[0008] The fixing mechanism includes non-standard bolts. Four non-standard bolts arranged in a ring array are movably connected inside the shell cover. Each non-standard bolt is threaded to the shell. Limiting holes are formed on the surface of each non-standard bolt. A limiting rod is slidably connected inside the shell cover, and the limiting rod is slidably connected to the limiting hole. An end buckle is fixedly sleeved on the outer side of the limiting rod, and a fixing disc is fixedly sleeved on the outer side of the limiting rod. The non-standard bolts allow for locking between the shell cover and the shell. The limiting holes and limiting rods also allow for insertion of the non-standard bolts, preventing them from loosening due to vibration.

[0009] Furthermore, in a preferred configuration, the inside of the cover has a locking hole, and a sealing disc is slidably connected inside the cover. The sealing disc contacts the non-standard bolt, and a locking head is slidably connected inside the sealing disc. The locking head is slidably connected to the locking hole, and an elastic element is bonded to the end face of the locking head away from the locking hole. The other end of the elastic element is bonded to the sealing disc. Through the combined use of the locking hole and the locking head, the sealing disc can be positioned, thereby sealing the non-standard bolt and preventing the non-standard bolt from being corroded by water.

[0010] Furthermore, in a preferred configuration, multiple limiting holes are provided, arranged in a circular array on the non-standard bolt. The limiting holes facilitate engagement with the limiting rod.

[0011] In addition, a preferred structure is that an elastic rope is bonded to the end face of the fixed plate away from the end buckle, and the other end of the elastic rope is bonded to the shell cover. The fixed plate can be connected and used by means of the elastic rope.

[0012] In addition, a preferred structure is that the sealing disc is fixedly connected to an end head on its front side, and the surface of the end head is provided with a plurality of friction grooves arranged in a ring array. The end head facilitates the movement of the sealing disc, and the friction grooves improve the friction effect of the end head surface, making it easier to pull the end head for use.

[0013] The beneficial effects of this utility model are as follows: by setting bolts, the cover and the shell can be locked together; with structures such as limiting holes, limiting rods, and elastic ropes, non-standard bolts can be inserted to avoid the problem of non-standard bolts loosening due to vibration; with structures such as locking holes and locking heads, sealing discs can be installed and used to protect non-standard bolts and prevent them from rusting after being invaded by moisture, thus preventing the structural strength of non-standard bolts from weakening.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A fixing structure for the housing of an AC / DC motor includes a housing 1, a housing cover 2 in contact with the front of the housing 1, a protective net 3 fixedly connected inside the housing cover 2, two symmetrically distributed support seats 4 fixedly connected to the lower side of the housing 1, and multiple heat dissipation grooves 5 arranged in a ring array on the surface of the housing 1.

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The cover 2 is provided with a fixing mechanism 6, which includes non-standard bolts 61. Four non-standard bolts 61 arranged in a ring array are movably connected inside the cover 2. Each non-standard bolt 61 is threaded to the housing 1. Limiting holes 62 are opened on the surface of the non-standard bolts 61. A limiting rod 63 is slidably connected inside the cover 2. The limiting rod 63 is slidably connected to the limiting hole 62. An end buckle 64 is fixedly sleeved on the outside of the limiting rod 63. A fixing plate 65 is fixedly sleeved on the outside of the limiting rod 63. Through the setting of non-standard bolts 61, the cover 2 and the housing 1 can be locked. With the limiting hole 62, the limiting rod 63 and other structures, the non-standard bolts 61 can be inserted to avoid the problem of vibration and loosening of the non-standard bolts 61.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The inside of the cover 2 is provided with a locking hole 67. A sealing disc 68 is slidably connected inside the cover 2. The sealing disc 68 contacts the non-standard bolt 61. A locking head 69 is slidably connected inside the sealing disc 68. The locking head 69 is slidably connected to the locking hole 67. An elastic element 690 is bonded to the end face of the locking head 69 away from the locking hole 67. The other end of the elastic element 690 is bonded to the sealing disc 68. Through the cooperation of the locking hole 67 and the locking head 69, the sealing disc 68 can be positioned, thereby sealing the non-standard bolt 61 and preventing the non-standard bolt 61 from being corroded by water.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Multiple limiting holes 62 are provided, and the multiple limiting holes 62 are arranged in a ring array on the non-standard bolt 61. The setting of the limiting holes 62 facilitates the use of the limiting rod 63 for snap-fit. An elastic rope 66 is glued to the end face of the fixed plate 65 away from the end buckle 64. The other end of the elastic rope 66 is glued to the shell cover 2. The setting of the elastic rope 66 allows the fixed plate 65 to be connected and used.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The sealing disc 68 is fixedly connected to an end 691 on its front side. The surface of the end 691 is provided with multiple friction grooves arranged in a ring array. The end 691 facilitates the movement of the sealing disc 68, and the friction grooves improve the friction effect of the surface of the end 691, making it easier to pull the end 691 for use.

[0025] The specific implementation process of this utility model is as follows: In use, by pulling the end buckle 64 upward, the limiting rod 63 is moved, and the fixing plate 65 is moved. The elastic rope 66 deforms, and then pushes the non-standard bolt 61 through the shell cover 2, so that the non-standard bolt 61 contacts the shell 1. With professional tools such as a flathead screwdriver, the non-standard bolt 61 can be rotated, so that the non-standard bolt 61 makes threaded movement, and the non-standard bolt 61 is fixed, thereby locking the shell cover 2. Then, the end buckle 64 is released so that the elastic rope 66 returns to its deformation, so that the limiting rod 63 is inserted into the limiting hole 62, and the non-standard bolt 61 is inserted to avoid the problem of vibration and loosening of the non-standard bolt 61.

[0026] By pushing the end 691, the sealing disc 68 is moved, causing it to slide into the cover 2 and come into contact with the non-standard bolt 61. During this process, the clamp 69 moves under the pressure of the edge of the cover 2 port, causing the elastic element 690 to deform and slide into the cover 2. Under the action of force, the clamp 69 slides along the inner wall of the cover 2. When the clamp 69 slides into the clamping hole 67, the elastic element 690 returns to its original shape, pushing the clamp 69 into the clamping hole 67 and limiting the sealing disc 68. This protects the non-standard bolt 61 from corrosion caused by water erosion.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
