Embodiment 1

[0030] Such as figure 1 As shown, the present invention provides a quick-response anti-pinch device, which includes a rotatable first gear 1;

[0031] The detection gear 2 meshes with the first gear 1;

[0032] The light-shielding grid distribution disc 4 is circular and arranged coaxially with the detection gear 2, defining this axis as the main shaft 7, and a plurality of light-shielding grids are also arranged on the radially outer edge of the distribution disc 4 Grid bar 5 (a plurality of light-shielding grid bars form an annular light-shielding grid), and the diameter of the distribution disc 4 is greater than the diameter of the detection gear 2;

[0033] It also includes a photoelectric switch 6, which is matched with the light-insulating grid strips 5, and forms intermittent signal pulses on the photoelectric switch 6 through the shielding effect of the light-insulating grid strips 5.

[0034] In the anti-pinch device of the present invention, by setting the detectio...

Embodiment 2

[0037] Such as figure 2 As shown, this embodiment is a transformation made on the basis of Embodiment 1, and the structural form in which the detection gear 2 meshes with the first gear 1 in Embodiment 1 is transformed into a detection gear meshing with the driving gear, and the active gear The gear is engaged with the first gear to drive the first gear to rotate.

[0038] Since the driving gear rotates in mesh with the first gear, the linear speed of rotation of the driving gear and the first gear is the same, and then the detection gear is meshed with the first gear or with the driving gear, and the result is that the detection gear is between the two. The linear speeds of rotation are the same, and combined with the coaxial arrangement of the light-shielding grid distribution disc and the detection gear, the diameter of the distribution disc is larger than the diameter of the detection gear, and finally the linear speeds of the light-shielding grid distribution discs of th...

Embodiment 3

[0048] Such as image 3 As shown, this embodiment is a further improvement made on the basis of Embodiment 1 and / or 2. Preferably, the photoelectric switch 6 includes a "concave" groove structure 61; the photoelectric switch 6 also includes a horizontal Arm 62, a first side arm 63 connected to one end of the cross arm and a second side arm 64 connected to the other end, and the first side arm 63 and the second side arm 64 are parallel to each other, so that The groove structure 61 is formed between the cross arm 62 and the first and second side arms 63 and 64; the photoelectric switch 6 and the distribution plate 4 are arranged so that the distribution plate 4 can accommodate each Each of the light-shielding grating bars 5 passes through the groove structure and cuts the vertical line between the first side arm 63 and the second side arm 64 to form a discontinuous shield to generate a pulse signal. .

[0049] This is the preferred structural form of the photoelectric switch ...

Abstract

The invention provides an anti-pinch device and an air-conditioning cabinet with the same. The anti-pinch device includes a rotatable first gear (1); a detection gear (2) meshing with the first gear (1) or The driving gear (3) used to drive the first gear (1) to rotate is meshed; the light-shielding grid distribution plate (4) is circular and coaxially arranged with the detection gear (2), and the axis is defined as the main shaft. And the radial outer edge of the distribution disc (4) is also provided with a plurality of light-shielding grid strips (5), and the diameter of the distribution disc (4) is larger than the diameter of the detection gear (2); it also includes a photoelectric switch (6) , which is matched with the light-shielding grid strips (5) to form intermittent signal pulses on the photoelectric switch (6) through the shielding effect of the light-shielding grid strips (5). The invention can effectively increase the speed at which the photoelectric switch receives the pulse signal, thereby realizing the quick response of the hand-clamping device and effectively preventing the occurrence of hand-clamping by the air outlet grille.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an anti-pinch device and an air conditioner cabinet equipped with the same. Background technique [0002] At present, the air outlet grille of the air-conditioning circular cabinet is easy to be touched by the user. In order to prevent the user from touching and causing safety hazards such as hand pinch, an anti-pinch device is usually installed, and the existing anti-pinch device is usually implemented by a photoelectric switch. A feedback method is used to perform feedback control and prevent the outlet grill from continuing to operate after encountering an obstacle. [0003] However, at present, the photoelectric switch detects the tooth shape fixed on the outlet grille. In this case, due to the slow wind sweeping speed, it takes a long time for the photoelectric switch to detect the abnormal running speed of the tooth shape, which makes it easy for custom...
