[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] Embodiment 1: Please refer to Figures 1 - 6, when the existing linear motor is in use, in order to facilitate the installation with the mounting base, corresponding mounting holes are opened. However, after the bolts are inserted into the interior of the mounting holes, the positions of the bolts cannot be adjusted. When there is a deviation between the positions of the screw holes on the linear motor and the screw holes on the mounting base, it is likely to affect the normal installation of the linear motor and the mounting base. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0039] Permanent magnet anti - detachment linear motor, including a linear motor body 1. A magnet 2 is inlaid at the upper end of the linear motor body 1, and heat dissipation fins 3 are fixedly connected to the side of the linear motor body 1. A power interface 4 that is inserted and matched with a power plug is installed on the linear motor body 1; A locking and anti - detachment component 5 that is butted with the mounting base is fixedly connected to the bottom of the linear motor body 1. The locking and anti - detachment component 5 is used to form an air flow channel between the bottom of the linear motor body 1 and the upper surface of the mounting base; The heat dissipation fins 3 are symmetrically arranged about the horizontal central axis of the linear motor body 1, and a plurality of heat dissipation fins 3 are evenly distributed at equal intervals on the side of the linear motor body 1. A plurality of locking and anti - detachment components 5 are evenly distributed at equal intervals at the bottom of the linear motor body 1, and the locking and anti - detachment component 5 includes a support frame 501, a guide groove 502, a connecting screw 503, a locking nut 504, and a shock - absorbing gasket 505; The support frame 501 is fixed to the bottom of the linear motor body 1, and a guide groove 502 is opened on the support frame 501. The connecting screw 503 is installed through the interior of the guide groove 502, and a locking nut 504 is threadedly connected to the connecting screw 503. A shock - absorbing gasket 505 is installed between the locking nut 504 and the support frame 501. The guide groove 502 is arranged in a kidney - shaped structure on the support frame 501, and the longitudinal section of the support frame 501 is arranged in a "U" - shaped structure. Locking nuts 504 are threadedly connected to both the upper and lower ends of the connecting screw 503, and the shock - absorbing gasket 505 between the locking nut 504 and the support frame 501 is made of rubber material.

[0040] When installing the linear motor body 1, place the support frame 501 at the bottom of the linear motor body 1 correspondingly on the mounting base. Then, pass the bolt through the guide groove 502 and into the screw hole on the mounting base. Since the guide groove 502 is arranged in a kidney-shaped structure on the support frame 501, the connecting screw 503 can be pushed in the guide groove 502 according to the position of the screw hole on the mounting base, thereby finely adjusting the position of the connecting screw 503. After inserting the connecting screw 503 into the screw hole on the mounting base, screw the locking nuts 504 at the upper and lower ends onto the connecting screw 503, thus completing the fixation between the linear motor body 1 and the mounting base. Through the support frame 501 at the bottom of the linear motor body 1, the lower surface of the linear motor body 1 and the upper surface of the mounting base can be separated from each other, enabling the outside air to circulate normally between the two, thereby improving the heat dissipation effect of the linear motor body 1. At the same time, by using the heat dissipation fins 3 evenly distributed on the side of the linear motor body 1, the heat dissipation effect of the linear motor body 1 can be further improved.

[0041] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. After the power supply interface 4 on the linear motor is connected to the power cord, it is not convenient to effectively limit the power cord connector, resulting in the power cord being prone to loosening after being pulled by an external force. To further solve this technical problem, the following technical content is disclosed in this embodiment, as Figures 1 - 6 shown;

[0042] A protective component 6 is installed outside the power supply interface 4 on the side of the linear motor body 1. The protective component 6 is used to fix the power plug and, when the power plug is not required to be inserted, provide waterproof and dustproof protection for the power supply interface 4. The protective component 6 includes a protective cover 601, a shielding plate 602, a built-in spring 603, and a rubber pad 604; the protective cover 601 is fixed on the side of the linear motor body 1 and is located outside the power supply interface 4. Two shielding plates 602 are installed on the protective cover 601, and the sliders on the shielding plates 602 are connected to the protective cover 601 through the built-in spring 603. A rubber pad 604 is installed in the middle of the shielding plate 602. The shielding plates 602 are symmetrically arranged about the vertical central axis of the protective cover 601, and the sliders on the two symmetrically distributed shielding plates 602 and the protective cover 601 form an elastic telescopic structure through the built-in spring 603.

[0043] When it is not necessary to connect the power interface 4 to an external power plug, the two shutter plates 602 shield the protective cover 601. At this time, the power interface 4 can be protected from dust through the shutter plates 602 and the protective cover 601. When it is necessary to connect the power plug to the power interface 4, push the shutter plate 602 to the outside of the protective cover 601, then insert the power plug into the inside of the power interface 4. After that, release the shutter plate 602. After the shutter plate 602 is released, it rebounds and resets under the action of the built-in spring 603. The power plug can be clamped and fixed through the reset shutter plate 602. By using the elastic deformation of the rubber pad 604 in the middle of the shutter plate 602, the contact area with the power plug can be increased.

[0044] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
