In this embodiment, as shown in fig. 6, the driven turntable 422 is provided with a driven turning post 424, and the driving shaft 421 is provided with a driving turning end 425 matching with the driven turning post 424. Thus, as the driving shaft 421 rotates, the driving toggle end 425 will press against the driven toggle column 424 and provide a rotational thrust for the driven rotary disk 422. One end of the connecting rod 435 is hinged to the driven toggle column 424, and the other end of the connecting rod 435 is hinged to the connecting end 433 of the sliding rod 431, so that the driven turntable 422, the connecting rod 435 and the sliding rod 431 form a crank-link structure, and the rotation of the driven turntable 422 can drive the sliding rod 431 to slide.

The operation principle of the safety lock 300 according to the present invention will be explained below by taking the first protection door 100 and the first lock mechanism 400 as examples in conjunction with the above-mentioned structure, and the operation principle of the second protection door 200 and the second lock mechanism 500 will be referred to below.

Meanwhile, for better explanation, as shown in fig. 7, the operation process of the security lock 300 is divided into four main states, and denoted by reference numerals 1 to 4:

the initial state of the safety lock 300 is shown as numeral 1 in fig. 7, in which the driven dial 424 is above the driving rotation shaft 421, the return elastic member 432 is in a compressed state, and under the elastic potential energy of the return elastic member 432, the sliding rod 431 has a tendency to slide leftward, and correspondingly, the driven dial 422 has a tendency to rotate in a counterclockwise direction as shown in fig. 7. However, since the one-way pawl 423 is engaged with the one-way ratchet wheel 411, so that the driven rotary disk 422 can only rotate clockwise as shown in fig. 7, the driven rotary disk 422 and the sliding rod 431 will be held and kept still at this time;

when unlocking, the rotating handwheel 600 rotates and drives the driving rotating shaft 421 to rotate, after the driving toggle end 425 of the driving rotating shaft 421 presses on the driven toggle column 424, the driving rotating shaft 421 will drive the driven rotating disc 422 to rotate clockwise as shown in fig. 7, the safety lock 300 changes from number 1 to number 2, during which the sliding rod 431 slides to the right, and the return elastic element 432 is further compressed. When the driven toggle column 424 rotates to the limit position (the rightmost side of the driving rotating shaft 421), the connecting rod 435 is parallel to the sliding rod 431, and at this time, the sliding rod 431 slides to the limit position rightwards, the locking end 434 of the sliding rod 431 is disengaged from the locking groove, the first protective door 100 can be opened smoothly, and the state of the safety lock 300 is shown by the numeral 3;

when locking, first guard gate 100 is closed earlier, rotatory hand wheel 600 that rotates once more afterwards, and then drive initiative pivot 421 and driven turntable 422 clockwise rotation an angle, at this moment, driven dial post 424 is in initiative pivot 421 below, driven turntable 422 has the trend of following the clockwise rotation as shown in fig. 7, one-way pawl 423 can not block each other with one-way ratchet 411, the elastic potential that resets elastic component 432 and amass releases rapidly, the locking end 434 of slide bar 431 slides left and stretches into the locked groove, the state of safety lock 300 is shown by numeral 4. Subsequently, the safety lock 300 will be reset to the initial state rapidly, specifically, when the reset elastic member 432 releases the elastic potential energy rapidly, the driven rotary disk 422 also rotates rapidly, due to the inertia, the driven dial column 424 will rotate above the driving rotary shaft 421 again, the reset elastic member 432 is compressed again, the kinetic energy of the rotation of the driven rotary disk 422 is converted into the elastic potential energy of the reset elastic member 432, until the driven rotary disk 422 stops, the state of the safety lock 300 is changed from the number mark 4 to the number mark 1, that is, the safety lock 300 returns to the initial state. In the initial state, the locking end 434 of the sliding rod 431 is still in the locking groove, and the first protection door 100 cannot be smoothly opened, so that the locking operation is completed.

It should be noted that the locking end 434 of the sliding rod 431 can be disengaged from the locking groove only when the driven toggle lever 424 is at the extreme position (the rightmost side of the driving rotary shaft 421), so that the first protection door 100 can be smoothly opened. Moreover, in order to improve the unlocking difficulty of the safety lock 300, the safety lock 300 of the present invention has two interferences, specifically as follows: firstly, the driven turntable 422 can only rotate in one direction, but the driving rotating shaft 421 can rotate freely, only when the driving rotating shaft 421 rotates in a specified direction, the driving toggle end 425 can be pressed and pushed to push the driven toggle column 424, if the driving toggle end 425 rotates in the opposite direction, even if the driving toggle end 425 is pressed and held on the driven toggle column 424, the driven turntable 422 cannot overcome the clamping of the one-way pawl 423; secondly, the rotating hand wheel 600 needs to be rotated to a designated position, so that the driven poking column 424 is in the limit position, and the unlocking can be realized, and if the rotating hand wheel 600 passes through the designated position in the rotating process, the safety lock 300 can be quickly reset to the initial state (the number mark 3 in fig. 7 is changed into the number mark 1). Therefore, the unlocking difficulty of the safety lock 300 is improved, and only an operator familiar with the structure of the safety lock 300 can unlock the safety lock smoothly, so that the property safety of equipment in the protection zone 22 is protected.

In this embodiment, as shown in fig. 6, the driven turntable 422 is a sector structure, so that the driven turntable 422 has an effect of a flywheel, and in the process of rapidly releasing the elastic potential energy of the reset elastic member 432, the driven turntable 422 can obtain greater kinetic energy and convert the kinetic energy into the potential energy of the system in the process of resetting the safety lock 300 to the initial state, so that the movement of the safety lock 300 can be more stable. Preferably, as shown in fig. 6, the return elastic member 432 is a spring structure, so that it can better cooperate with the driven turntable 422 to accumulate and release potential energy.

In conclusion, the environment-friendly dust removal equipment 10 suitable for the polishing field can timely perform dust removal treatment in the workpiece polishing process, reduce pollution of dust to the environment or workpieces, and improve production efficiency.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
