Description

Flat push button and air conditioner indoor unit

Technical Field

The invention relates to an air conditioner, in particular to a flat push button for fixing a movable outer cover and a movable base of an air conditioner indoor unit and the air conditioner indoor unit provided with the flat push button.

Background

As shown in fig. 14, when the movable cover 41 is pivotally assembled to the movable base 42, a hook (not shown) provided on the movable cover 41 is engaged with a groove 43 provided on the movable base 42. Since the rear of the clamping groove 43 on the movable base 42 is a pipe passing space without a supporting structure, the structural strength of the clamping groove 43 is weaker. When the movable housing 41 is assembled with the movable base 42, the movable base 42 is subjected to the tangential vertical stress of the movable housing 41, so that the movable base 42 is easily deformed backward, and finally the hooks of the movable housing 41 cannot be clamped into the clamping grooves 43 of the movable base 42 at one time. The hook can be locked only by pressing the buckling position of the movable outer cover 41 and the movable base 42 at the same time. The operation of confirming whether the hook is in place later is needed, the operation cannot be controlled in production, and when the user is cleaning the air conditioner and fastening the movable housing 41, the fastening position is not fastened in place, so that the risk that the movable housing 41 is loosened under the action of gravity in the use process of the air conditioner is caused. Meanwhile, if the hook member is loosely fitted, the movable housing 41 and the movable base 42 may be loosened even if they are assembled in place. And the hidden trouble is buried in the product quality.

Disclosure of Invention

The technical problems to be solved by the invention are as follows: the flat push button is characterized in that the movable outer cover and the movable base of the air conditioner indoor unit are fixedly connected at one time in the assembly process, whether the movable outer cover and the movable base are firmly connected does not need to be confirmed by subsequent people, the flat push button cannot fall off when no manual operation is performed, and the movable outer cover and the movable base are assembled safely and reliably.

The technical scheme includes that the flat push buckle is provided with a strip-shaped substrate structure, a flat push buckle handle is arranged on the upper portion of the substrate, a first clamping hook is arranged on one side of the lower portion of the substrate, the root portion of the first clamping hook is fixedly connected with the substrate, the hook portion of the first clamping hook extends towards the outer side of the substrate along the axial direction, a first limiting rib is arranged on one side, opposite to the first clamping hook, of the lower portion of the substrate along the longitudinal direction, a second limiting rib is arranged between the first clamping hook and the first limiting rib, a pair of central elastic arms are arranged on the middle position, opposite to the axial direction, of the lower portion of the substrate, a second clamping hook is arranged on the top end of the central elastic arm, and the hook portion of the second clamping hook extends towards the outer side of the substrate.

Further, the first limiting rib is of a trapezoid structure with first guide inclined planes at two sides.

The invention also provides an air conditioner indoor unit which comprises a movable outer cover and a movable base, and is characterized in that the movable outer cover is movably connected with the movable base through the flat push buckle.

Further, a first installation position of the flat push button for installing the flat push button is arranged on the movable outer cover, and a second installation position of the flat push button, which is connected with the flat push button in a matched mode, is arranged on the movable base.

In the present embodiment, the first hook 13 is provided at a right side position of the lower portion of the base plate 16 in the direction of the front view flat push button 1. A first stopper rib 14 is provided in the longitudinal direction at a side opposite to the first hook 13 at the lower portion of the base plate 16. A second limiting rib 15 is arranged between the first clamping hook 13 and the first limiting rib 14, and the second limiting rib 15 is of a protruding structure. As shown in fig. 8, a pair of central elastic arms 12 are oppositely disposed at the middle position of the lower portion of the base plate 16 along the axial direction, the top end of the central elastic arm 12 is provided with a second hook 17, and the hook portion of the second hook 17 extends toward the outer side of the base plate 16.

The invention also provides an air conditioner indoor unit, which comprises a movable outer cover 41 and a movable base 42, wherein the movable outer cover 41 is movably connected with the movable base 42 through the flat push buckle 1. The movable housing 41 is provided with a first flat push button installation position 2 for installing the flat push button 1, and the movable base 42 is provided with a second flat push button installation position 3 which is matched and connected with the flat push button 1. Specifically, as shown in fig. 10-11, the first mounting position 2 of the push button on the movable housing 41 is in a strip-shaped hollow structure, and third limiting ribs 21 are respectively arranged on two opposite sides of the strip-shaped hollow structure along the axial direction, and the third limiting ribs 21 in the embodiment are in a boss structure, and the second hooks 17 on the push button 1 are in contact fit with the third limiting ribs 21 and can slide left and right along the third limiting ribs 21. A third clamping hook 22 is arranged at one end part of the first installation position 2 of the horizontal pushing buckle.

Referring to fig. 1, when the push button 1 is assembled with the movable outer cover 41, the handle 11 of the push button is held by hand, the push button 1 is aligned to the first mounting position 2 of the push button on the movable outer cover 41, the push button 1 is pressed towards the inner side of the first mounting position 2 of the push button by force, so that the central elastic arm 12 is forced to be close to each other and deformed, the second hook 17 is inserted into the hollow structure of the first mounting position 2 of the push button, the hook portion of the second hook 17 is clamped with the third limiting rib 21, at this time, the push button 1 is in an OPEN state, and the first limiting rib 14 is limited by the third hook on the first mounting position 2 of the push button and cannot move under the condition of not being subjected to external force. The third hook 22 is located between the first limiting rib 14 and the second limiting rib 15 and abuts against the second limiting rib 15 at this time, so that the push button 1 will not fall off the movable housing 41 even if the push button 1 is manually slid left and right along the third limiting rib 15. Fig. 3 is a schematic view of the structure of the push button 1 when the push button is fixed to the movable housing 41 in the OPEN state and the movable housing 41 is turned up.

As shown in fig. 12-13, the second installation position 3 of the push button on the movable base 42 is provided with a movement groove 31 for sliding the first hook 13, and one end of the movement groove 31 is provided with a first hook clamping part 32 for limiting the first hook 13.
