Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The application discloses a pot cover in-place device.

Referring to fig. 1 and 2, the pot cover positioning device comprises a connecting arm 7 fixed on the pot cover, a sensor 4 and a locking mechanism; the locking mechanism and the sensor 4 are both fixedly connected to the connecting arm 7; the pot cover positioning device also comprises a fixedly arranged inserting plate 6, and a through hole 61 is formed in the inserting plate 6; the locking mechanism comprises a locking head 21 and a power part, the power part is used for driving the locking head 21 to move close to or far away from the connecting arm 7, and the sensor 4 is electrically connected with the power part; when the connecting arm 7 moves relative to the plug board 6 until the plug board 6 is sensed by the sensor 4, the power part drives the locking head 21 to move and penetrate through the through hole 61.

Because the inserting plate 6 is fixed at a preset position, when the connecting arm 7 moves along with the cooker cover, and when the sensor 4 senses the inserting plate 6, the sensor 4 starts the power part switch to enable the locking head 21 to move and penetrate into the through hole 61 on the inserting plate 6, at the moment, because the locking head 21 is matched with the through hole 61, the relative movement of the connecting arm 7 and the inserting plate 6 is limited, and therefore the cooker cover is fixed on the inserting plate 6 through the connecting arm 7 and does not move.

The inserting plate 6 can be a rectangular plate, and can also be other shapes such as an oval plate or a diamond plate. The connecting arm 7 may be an elongated plate, preferably a rectangular plate. The connecting arm 7 is provided with a locking hole 71, and the locking head 21 can simultaneously penetrate through the through hole 61 and the locking hole 71. Thus, the connecting arm 7 and the inserting plate 6 are limited by the locking head 21 to move, when the connecting arm 7 tends to move relative to the inserting plate 6 due to external force, shearing force is concentrated on the locking head 21, and the influence of stress load on a power part is reduced.

In order to improve the structural strength of the connecting arm 7, the connecting arm 7 may include at least two layers of plate bodies, the locking hole 71 penetrates through the plate bodies of the connecting arm 7, and the inserting plate 6 is located between the two adjacent layers of plate bodies. The connecting arm 7 can here be formed fixedly as a two-layer plate body.

The power part can be a cylinder 2, and the cylinder 2 is fixed with a connecting arm 7 through a bolt. The locking head 21 is fixed at the end of the piston rod of the cylinder 2, and the piston rod of the cylinder 2 is perpendicular to the plate body of the connecting arm 7. The power part can also be a linear motor or other mechanical mechanisms capable of performing linear reciprocating motion according to requirements.

The locking head 21 and the piston rod may be welded, threaded or keyed. Here a threaded connection is used in order to facilitate replacement and maintenance after wear of the locking head 21. The locking head 21 may be a cylinder or a prism, and the locking head 21 may have other shapes as long as the outer contour can extend into the through hole 61. Preferably, the contour of the locking head 21 is matched with the contour of the through hole 61, and preferably, the aperture of the through hole 61 is slightly larger than the outer diameter of the locking head 21, and the clearance is between 0.5 and 1 mm.

In order to reduce the impact of the power part 2 and the sensor 4 from the outside, the pot cover positioning device also comprises a cover 1 with a hollow inside, the cover 1 is fixed on the connecting arm 7, and the locking mechanism and the sensor 4 are fixed in the cover 1.

In order to reduce the influence of dust and dirt on the locking hole 71 exposed outside and the locking, the part of the connecting arm 7 with the locking hole 71 is positioned in the casing 1, and the casing 1 is provided with a socket 12 for inserting the plug board 6. The width of the socket 12 is adapted to the dimensions of the board 6.

An installation plate 3 and a fixed plate 5 are fixed in the housing 1, the power part is fixed on the installation plate 3, and the sensor 4 is installed on the fixed plate 5. The mounting plate 3 and the fixing plate 5 can be directly fixed on the inner wall of the housing 1 by welding, bonding or bolt connection. Because sensor 4 and power portion install in different plate bodies, reduced the influence of power portion during operation to sensor 4 position, improved sensor 4's response degree of accuracy. The sensor 4 may be an infrared sensor or a pressure sensor.

In order to adjust the position of the sensor 4, the fixing plate 5 and the mounting plate 3 may be further provided as follows: a strip-shaped hole is formed in the fixing plate 5, the length direction of the strip-shaped hole is arranged along the direction of the inserting plate 6 moving relative to the housing 1, and the fixing plate 5 is connected to the connecting arm 7 through a bolt penetrating through the strip-shaped hole. The mounting plate 3 may be a rectangular plate, and the fixing plate 5 may be an L-shaped plate. In order to adapt to the adjustment of the sensor 4, the connecting arm 7 is provided with a receding hole 72 corresponding to the position of the sensor 4.

In order to make it easier for the sensor 4 to sense the end of the board 6, the insertion hole 61 of the board 6, the locking hole 71 of the connecting arm 7, and the axis of the sensor 4 are on the same plane. When the card 6 is not a rectangular plate but an L-shaped plate, the sensor 4 may not be located on the center connecting line of the jack 61 and the locking hole 71.
