Example 2

The same points as those in example 1 are not repeated, and the difference from example 1 is that:

referring to fig. 6-7, the sealing frame 124 includes two horizontal rods and two vertical rods, and the vertical rods are symmetrically distributed at the two ends of the cross rod, the vertical rods comprise a first rod 1242 and a second rod 1241, the end of the first rod 1242 is provided with a sliding slot 12422 for sliding connection of the second rod 1241, a second spring 12421 which is fixedly connected and used for automatically contracting the second rod 1241 is arranged in the sliding chute 12422, the second spring 12421 is fixedly connected with the end of the corresponding second rod 1241, the dust cover 123 is respectively fixedly connected with the cross rod and the vertical rod, the first rod 1242 and the second rod 1241 are provided with extrusion slots which are aligned and communicated with each other, the cross section of the extrusion groove is convex, the bottom of the corresponding dust cover 123 is positioned in the middle of the extrusion groove, a plurality of clamping rings which are uniformly distributed are arranged in the extrusion groove, and the upper ends of the clamping rings are fixedly connected with the bottoms of the corresponding dust covers 123 respectively.

When the height of the machine body 11 is too high, the height of the dustproof plate 12 is inevitably too high, so that after the sealing frame 124 rotates, the tiled size of the sealing frame 124 is inevitably larger than that of the surface of the machine body 1, a leakage position appears after sealing, and the whole dustproof effect is influenced;

due to the design of the first rod 1242 and the second rod 1241, after the sealing frame 124 rotates to be horizontal, the sealing frame 124 can be contracted in the first rod 1242 through the second rod 1241, so that the sealing frame 124 can cover the surface of the machine body 1 more accurately, the leakage situation is solved, and the integral sealing and dust-proof effect is ensured;

due to the design of the extrusion groove and the clamping ring, the second rod 1241 does not influence the movement of the dust cover 123 when being contracted, and the dust cover 123 can be effectively fixed in the extrusion groove, so that the integral sealing and dust preventing effect is guaranteed.

Further, one end of the first rod 1242 is provided with a rotating shaft 129 rotatably connected to the bottom of the corresponding shrinkage groove 127, the bottom of the other end of the first rod 1242 is provided with an unlocking groove 12426, an unlocking rod 12423 capable of sliding up and down is arranged in the unlocking groove 12426, the bottom of the second rod 1241 located on one side of the second spring 12421 is provided with a clamping groove 1241, and a clamping rod 12413 capable of moving up and down and used for clamping and fixing the unlocking groove 12426 is arranged in the clamping groove 1241.

The design of kelly 12413, make first pole 1242 and second pole 1241 after the extension, can effectually go fixedly, and the design of unblock pole 12423, make sealed frame 124 when rotatory to the level form, can extrude unblock pole 12423, unblock pole 12423's transmission, drive kelly 12413 shrink to draw-in groove 1241 in, second pole 1241 is because the elasticity of second spring 12421, automatic contraction, make sealed frame 124 can the automatically regulated distance, can effectually laminate organism 1 surface more with sealed frame 124, guarantee holistic sealed dirt resistance.

Further, be equipped with the third spring 12412 that is used for kelly 12413 auto-eject in the draw-in groove 1241, third spring 12412 one end and draw-in groove 1241 inner wall fixed connection, and the third spring 12412 other end and kelly 12413 end fixed connection are located unlocking lever 12423 both ends be equipped with symmetric distribution's spacing groove 12425 on the unlocking groove 12426 inner wall, be equipped with sliding connection's limit slider 12424 in the spacing groove 12425, limit slider 12424 respectively with corresponding unlocking lever 12423 both ends fixed connection.

When the application is used:

when the machine is not ready for use, the dust guard 12 is firstly pulled out of the hidden groove 125, and when the positioning rod 1263 moves to the positioning groove 1264, the positioning rod 1263 automatically pops up due to the elasticity of the first spring 1262 and is clamped in the positioning groove 1264, so that the dust guard 12 is fixed;

after the dust guard 12 is fixed, the sealing plate is rotated outwards, and the sealing plate drives the dust guard 123 to cover the machine body 11;

when the sealing plate moves to a horizontal state, the unlocking rod 12423 is extruded inevitably, the clamping rod 12413 is synchronously extruded through the unlocking rod 12423, the second rod 1241 automatically contracts into the first rod 1242 due to the elasticity of the second spring 12421, so that the size of the sealing frame 124 is the same as that of the upper surface of the machine body 1, the sealing frame 124 can be effectively fit with the surface of the machine body 1, and the whole sealing and dust-proof performance is ensured;

when the machine needs to be used, the cross rod is only required to be outward, the first rod 1242 and the second rod 1241 are extended to the initial length, the clamping rod 12413 is clamped with the clamping groove 1241, the first rod 1242 and the second rod 1241 are guaranteed to be fixed, then the sealing frame 124 is rotated into the contraction groove 127, and the dust cover 123 is contracted and folded in the contraction groove 127 while the sealing frame 124 is rotated; after the sealing frame 124 rotates to the inside of the contraction groove 127, the sealing frame 124 is pressed again, the transmission rod 120 is driven to extrude the transmission line 122, the positioning rod 1263 is made to contract synchronously, the locking of the dust-proof plate 12 is released, then the dust-proof plate 12 can be recovered to the hidden groove 125, the whole operation is convenient and fast.
