[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 4 In an embodiment of the present invention, a magnetic attraction structure for a lathe side door switch includes a sliding door assembly 1 consisting of a side sliding door 101 and a handle 102. The handle 102 is fixed to the end surface of the outer wall of the side sliding door 101. A telescopic slot 103 is provided on the folded edge of one side of the side sliding door 101. A fixed baffle 104 is fixedly connected to the other end surface of the side sliding door 101. A limiting guide plate 105 is fixedly connected between the fixed baffle 104 and the folded edge of the side sliding door 101. A rotating slot 106 is provided inside the handle 102 and extends to the top of the handle 102.

[0028] A magnetic component 2 is provided between the rotating groove 106 and the limiting guide plate 105 and the side sliding door 101. The magnetic component 2 cooperates with the sealing component 3 to achieve a sealing operation between the side sliding door 101 and the outer wall of the lathe. The sealing component 3 is adhesively fixed to the side of the outer wall of the lathe.

[0029] The magnetic assembly 2 includes a magnetic base 201, which is horizontally slidably connected to the inner side of the telescopic slot 103 and extends between the sliding door 101 and the fixed baffle 104;

[0030] The sealing assembly 3 includes a magnetic edge strip 301, a corrugated rubber strip 302, and a fixed rubber strip 303. The magnetic edge strip 301, the corrugated rubber strip 302, and the fixed rubber strip 303 are fixed in sequence along the horizontal direction. The fixed rubber strip 303 is adhesively fixed to the side of the outer wall of the lathe. The magnetic edge strip 301 faces the side of the sliding door 101.

[0031] When the side sliding door 101 is close to the magnetic edge strip 301, the corrugated rubber strip 302 is extended and contracted to achieve buffering of the side sliding door 101, and the magnetic edge strip 301 and the magnetic seat 201 are mutually attracted to each other to achieve sealing between the side sliding door 101 and the outer wall of the lathe;

[0032] The magnetic attraction assembly 2 further includes a spring piece 202, a through slot 203, a lower pressing plate 204, a rotating shaft 205 and an extrusion plate 206;

[0033] The spring piece 202 is bonded and fixed to one side of the outer wall of the magnetic base 201 and fixed to the side wall of the fixed baffle 104. The through slot 203 is opened at one end of the magnetic base 201 and passes through the other end of the through slot 203.

[0034] The rotating shaft 205 is rotatably connected to the inner side of the handle 102. The lower pressure plate 204 is fixed to one end of the rotating shaft 205 and extends to the top of the handle 102 through the rotating groove 106. The other end of the rotating shaft 205 passes through the side sliding door 101 and extends to the inner side of the through groove 203. The extrusion plate 206 is fixed to the other end of the rotating shaft 205 and fits against the inner wall side of the through groove 203.

[0035] The lower pressing plate 204 rotates to drive the extrusion plate 206 to squeeze the inner wall of the through groove 203, so as to shrink the magnetic seat 201, thereby releasing the adsorption state between the magnetic seat 201 and the magnetic edge strip 301;

[0036] The cross-sectional width of the magnetic edge strip 301 matches the cross-sectional width of the side of the sliding door 101 , and the cross-sectional width of the magnetic edge strip 301 is greater than the cross-sectional width of the magnetic base 201 .

[0037] In this embodiment, it should be noted that the side sliding door 101 is mounted on the lathe by means of accessories such as a slide rail and a slide seat, the fixing strip 303 is fixed to the side of the outer wall of the lathe by means of glue, and another magnetic edge strip is bonded and fixed to the side of the magnetic base 201 facing the magnetic edge strip 301;

[0038] When using the sliding door 101, the operating steps are as follows:

[0039] When the side sliding door 101 is manually pushed, the operator holds the handle 102, and the operator's hand contacts the lower pressing plate 204 at the same time and squeezes the lower pressing plate 204 to be stored in the rotating groove 106. At this time, the lower pressing plate 204 drives the squeezing plate 206 to rotate through the rotating shaft 205, and the squeezing plate 206 squeezes the side surface of the inner wall of the through groove 203. This squeezing force causes the magnetic seat 201 to move closer to the fixed baffle 104 and squeeze the spring piece 202 to deform and shrink, and the magnetic seat 201 will shrink to the inside of the side sliding door 101;

[0040] Then, a thrust is applied to the side sliding door 101 to move it closer to the sealing assembly 3. When the side sliding door 101 contacts the magnetic edge strip 301, it is squeezed, and the corrugated rubber strip 302 is deformed under the force. This can cushion the movement of the side sliding door 101, avoiding hard collisions and effectively preventing noise caused by hard collisions.

[0041] After that, the handle 102 is released, and the lower pressing plate 204 loses the external squeezing force. At this time, the magnetic seat 201 is reset under the elastic force of the spring piece 202, and the squeezing plate 206 and the lower pressing plate 204 are synchronously reset to the initial state. The magnetic seat 201 enters the telescopic slot 103 and approaches the magnetic edge strip 301. At this time, the magnetic edge strip 301 and the other magnetic edge strip on the magnetic seat 201 are attracted to each other, thereby maintaining a good sealing effect between the side sliding door 101 and the side of the lathe.

[0042] When the side sliding door 101 needs to be opened, the handle 102 is also grasped to make the magnetic seat 201 shrink, and the adsorption between the magnetic seat 201 and the magnetic edge strip 301 is released. Then the side sliding door 101 can be pulled to open. During this process, the magnetic edge strip 301 will not be pulled, thereby preventing the corrugated rubber strip 302 from being deformed by the tension. This structure can effectively improve the service life of the sealing component 3 (it should be noted that: if the magnetic seat 201 does not shrink, it will pull the magnetic edge strip 301, causing the corrugated rubber strip 302 to be pulled and unfolded. Finally, when the pulling force is greater than the magnetic attraction force of the magnetic edge strip, the magnetic seat 201 and the magnetic edge strip 301 can be separated. In this way, under frequent pulling, the corrugated rubber strip 302 is easily damaged, has a short service life, and makes it more difficult to pull the side sliding door 101).

[0043] Please refer to Figures 1 to 4 When the lower pressing plate 204 is completely received in the rotating groove 106 , the top of the squeezing plate 206 forms an acute angle with the inner side of the through groove 203 .

[0044] In this embodiment, this structure allows the magnetic seat 201 to be reset under the elastic force of the spring piece 202 , and can squeeze the extrusion plate 206 to rotate and reset it.

[0045] Please refer to Figures 1 to 4The trajectory and thickness of the magnetic base 201 match the trajectory and thickness of the telescopic slot 103 respectively. A plurality of limiting guide plates 105 are provided. The distribution trajectory of the plurality of limiting guide plates 105 matches the trajectory of the magnetic base 201, and the distance between the fixed baffle 104 and the end surface of the sliding door 101 matches the thickness of the magnetic base 201.

[0046] There are multiple spring pieces 202 , and the multiple spring pieces 202 are evenly distributed along the trajectory of the magnetic base 201 .

[0047] In this embodiment, this structure can make the movement of the magnetic base 201 more stable, effectively improving the operating stability of the device.

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
