DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0032] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0033] Figure 1-Figure 10 As shown, the switch locking structure on the polishing machine includes a shell 1 and a switch button 2 arranged on the shell 1 and capable of rebounding after being pressed. One end of the switch button 2 is connected to the shell 1, and the other end of the switch button 2 is tilted and suspended on the outside of the shell 1 for pressing.

[0034] The structure of the switch push plate 2 and the rebound structure are the same as those of the push switch on the existing polishing machine.

[0035] For example, one end of the switch plate 2 is hinged on the housing 1, and the other end of the switch plate 2 is tilted and suspended on the outside of the housing 1. The switch plate 2 can rebound by the switch rebounding when touched, or an elastic member is arranged between the switch plate 2 and the housing 1 to drive the switch plate 2 to rebound.

[0036] Figure 8-Figure 10As shown, as shown in the accompanying drawings, two buckles 15 are provided at the bottom of one end of the switch plate 2, and two slots 18 corresponding to the two buckles 15 are provided on the housing 1, and buckle grooves 17 are provided in the slots 18. Buckle parts 16 are convexly provided at the ends of the two buckles 15, and the two buckle parts 16 are respectively arranged on the side walls of the two buckles 15 away from each other. When the two buckles 15 are inserted into the slots 18, the buckle parts 16 are snapped into the corresponding buckle grooves 17, so that one end of the switch plate 2 is connected to the housing 1, and the switch plate 2 can be turned over with the buckle parts 16 on both sides as the center. A convex rib 20 is provided at the bottom of the switch plate 2, and a guide groove 19 cooperating with the convex rib 20 is provided on the housing 1, and the guide groove 19 is connected with the slots 18. When the switch plate 2 is turned over with the buckle parts 16 on both sides as the center, the convex rib 20 is inserted in the guide groove 19 and moves along the guide groove 19 to improve the stability of the switch plate 2 turning over. The switch button 2 can rebound by the switch rebounding when pressed, or an elastic member is arranged between the switch button 2 and the housing 1 to drive the switch button 2 to rebound.

[0037] Figure 1-Figure 4 As shown, a stopper 4 corresponding to the switch plate 2 is movably connected to the housing 1, and the stopper 4 is movable relative to the housing 1 to change between the locked position and the unlocked position. When the stopper 4 is in the locked position, the stopper 4 is pressed on the switch plate 2 after being pressed to limit the rebound of the switch plate 2, so that the switch plate 2 is in a normally closed state, avoiding the need to press the switch plate 2 all the time during use, freeing the user's fingers for pressing, and making it easier to use. When the stopper 4 is in the unlocked state, the stopper 4 moves out from the top of the switch plate 2, so that the top of the switch plate 2 is not restricted, the switch plate 2 can rebound, and the free end of the switch plate 2 is tilted and suspended on the outside of the housing 1. At this time, the polishing machine is in a shutdown and disconnected state.

[0038] The movement of the pressing member 4 relative to the housing 1 may be rotation, movement, or a combination of rotation, movement and other movement modes.

[0039] Figure 3-Figure 7 As shown, preferably, the pressure stopper 4 is arranged on the housing 1, and the pressure stopper 4 can rotate relative to the housing 1, and the pressure stopper 4 is driven by an external force to realize a rotational transformation between the unlocking position and the locking position.

[0040] In addition, the pressing member 4 can move up and down relative to the housing 1, and an elastic reset member 13 is provided between the pressing member 4 and the housing 1 to reset the pressing member 4 by pressing it downward.

[0041] Figure 4As shown, preferably, the pressure stopper 4 includes a pressure plate 9 and a connecting shaft 10 arranged on the housing 1, one end of the connecting shaft 10 is exposed outside the housing 1, and the other end of the connecting shaft 10 passes through the side wall of the housing 1 and extends into the housing 1, the connecting shaft 10 can rotate around its own axis relative to the housing 1, and the connecting shaft 10 can move up and down along its axis relative to the housing 1, the pressure plate 9 is fixed on the end of the connecting shaft 10 exposed outside the housing 1, the elastic reset member 13 is a reset spring, and the reset spring is arranged between the connecting shaft 10 and the housing 1 to drive the connecting shaft 10 and the pressure plate 9 to move downward and reset, and the housing 1 is provided with a through hole 11 for the connecting shaft 10 to pass through. The diameter of the connecting shaft 10 matches the aperture of the through hole 11. The pressure plate 9 rotates around the axis of the connecting shaft 10.

[0042] Preferably, the pressing plate 9 and the connecting shaft 10 are integrally formed, or the pressing plate 9 and the connecting shaft 10 are fixedly connected by other conventional fixing methods.

[0043] Specifically, a limiting portion 12 is fixed on the end of the connecting shaft 10 located inside the shell 1, a reset spring is sleeved on the connecting shaft 10, and both ends of the reset spring are respectively supported on the inner wall of the shell 1 and the limiting portion 12, the elastic force of the reset spring acts on the limiting portion 12, driving the limiting portion 12, the connecting shaft 10 and the pressure plate 9 to move downward and reset, so that the pressure plate 9 contacts and presses on the outer wall of the shell 1.

[0044] Preferably, the limiting portion 12 is an annular sleeve, which is sleeved on the lower end of the connecting shaft 10 . The annular sleeve can be threadedly connected to the connecting shaft 10 , or the annular sleeve can be bonded to the connecting shaft 10 .

[0045] Figure 7 As shown, when the switch plate 2 is pressed by external force, the pressing plate 9 can be lifted so that the pressing plate 9 is slightly moved up to a position higher than the pressed switch plate 2, and the pressing plate 9 is rotated so that the pressing plate 9 is moved above the switch plate 2. Then the pressing plate 9 is released, and the pressing plate 9 loses its force so that the return spring drives the limit part 12, the connecting shaft 10 and the pressing plate 9 to move downward, thereby pressing the pressing plate 9 down on the pressed switch plate 2 to limit the rebound of the switch plate 2.

[0046] The stopper 4 moves up and down relative to the housing 1 , so that the pressing plate 9 has a certain amount of room for movement when in use, thereby preventing the pressing plate 9 from contacting the switch pressing plate 2 and failing to press on the switch pressing plate 2 when the pressing plate 9 is rotated.

[0047] Figure 2As shown, in addition, a boss 6 is provided on the housing 1, and the pressure stopper 4 is arranged to rotate on the boss 6. The boss 6 is provided with a convex edge 7 surrounding the outer side of the pressure stopper 4 to limit the rotation range of the pressure stopper 4. Preferably, the convex edge 7 is provided on a circle of the outer edge of the boss 6, and a notch 8 is provided on the convex edge 7 for the pressure stopper 4 to rotate out of the boss 6 to press the switch button 2. The pressure stopper 4 is blocked by the convex edges 7 on both sides of the notch 8 to limit the rotation range of the pressure stopper 4. Preferably, the boss 6 is integrally formed with the housing 1.

[0048] When the pressure plate 9 rotates to the locking position around the axis of the connecting shaft 10, the pressure plate 9 rotates out of the notch 8 from the boss 6, so that a part of the pressure plate 9 protrudes from the boss 6 to press the switch button 2; when the pressure plate 9 rotates to the unlocking position around the axis of the connecting shaft 10, the pressure plate 9 is rotated as a whole into the boss 6 for storage to avoid interference with the switch button 2.

[0049] Preferably, the switch plate 2 is provided with a notch groove 5 that cooperates with the pressure stopper 4. The notch groove 5 is arranged at a circle edge of the switch plate 2. When the pressure stopper 4 is rotated to a locked position relative to the housing 1, the pressure plate 9 is rotated into the notch groove 5 on the pressed switch plate 2 to press the switch plate 2.

[0050] Preferably, the notch groove 5 is located on the raised end of the switch button 2. When the pressing plate 9 rotates into the notch groove 5 to press the pressed switch button 2, the pressing plate 9 presses on the end of the switch button 2 to achieve a better limiting effect.

[0051] Preferably, the depth of the notch groove 5 is greater than or equal to the thickness of the pressing plate 9 , so that when the pressing plate 9 is rotated into the notch groove 5 , the pressing plate 9 will not protrude from the notch of the notch groove 5 .

[0052] Figure 6 As shown, in addition, an anti-slip portion 14 is provided on the pressing plate 9 and / or the notch groove 5 to prevent the pressing plate 9 from slipping when the pressing plate 9 is rotated into the notch groove 5 and presses the switch pressing plate 2.

[0053] Preferably, the lower end surface of the pressing plate 9 opposite to the notch groove 5 is provided with anti-skid stripes, and the bottom of the notch groove 5 opposite to the lower end surface of the pressing plate 9 is provided with anti-skid protrusions or convex patterns.

[0054] In addition, the switch button 2 is arranged on the top of the housing 1 . The top of the housing 1 is provided with a concave receiving groove 3 . The receiving groove 3 is used to receive the switch button 2 after being pressed. The stopper 4 is located around the receiving groove 3 .
