In order to solve the problems, the invention provides a telescopic handle and an air conditioner with the telescopic handle.
Referring to fig. 1 and 2, in the present embodiment, the air conditioner includes an air conditioner main unit and a mover 20; the mobile sub-unit 20 is detachably arranged on the air conditioner main unit, and the mobile sub-unit 20 comprises a shell 21 and a telescopic handle 10 arranged on the shell 21.
Referring to fig. 3 to 5, in one embodiment, the telescopic handle 10 includes a handle grip 100, a mounting box 200, a connecting rod 300, an elastic member 400, and a limiting member 500; the mounting box 200 has a receiving chamber 210 formed therein; one end of the connecting rod 300 is disposed in the accommodating cavity 210, the other end is connected with the handle 100, and a first limiting portion 310 and a second limiting portion 320 are respectively disposed on the connecting rod 300 along the axial direction thereof; the elastic member 400 is disposed in the accommodating cavity 210 and connected to the connecting rod 300; one end of the limiting piece 500 is connected with the mounting box 200, and the other end of the limiting piece can be connected with the first limiting part 310 or the second limiting part 320, so that the connecting rod 300 is static relative to the mounting box 200; when the handle grip 100 moves close to the accommodating cavity 210 and the stopper 500 is separated from the first stopper 310 or the second stopper 320, the connecting rod 300 is ejected or retracted into the accommodating cavity 210 by the elastic member 400.
The first limiting portion 310 and the second limiting portion 320 are disposed along the axial direction of the connecting rod 300, and are different from the distance between the bottom walls of the accommodating cavities 210, the length of the limiting member 500 is fixed, and when the positions of the connecting rod 300 at one ends of the accommodating cavities 210 are different, the limiting member 500 is connected with different limiting portions. Taking the example that the second limiting portion 320 is closer to the bottom wall of the accommodating cavity 210 than the first limiting portion 310, and the connection position between the limiting member 500 and the mounting box 200 is closer to the bottom wall of the accommodating cavity 210, the elastic member 400 is disposed between the bottom wall of the accommodating cavity 210 and one end of the connecting rod 300 opposite to the handle 100, when the elastic member 400 is in a compressed state, the connecting rod 300 is pushed against under the action of elastic force, and the connecting rod 300 moves in a direction away from the bottom wall of the accommodating cavity 210. Meanwhile, the limiting piece 500 is connected with the mounting box 200 and the connecting rod 300, the limiting piece 500 limits the movement of the connecting rod 300, the pushing force of the elastic piece 400 to the connecting rod 300 and the pulling force of the limiting piece 500 to the connecting rod 300 are balanced, the position of one end of the connecting rod 300 in the accommodating cavity 210 is fixed, and the connecting rod 300 is static relative to the mounting box 200. When the limiting member 500 is connected to the first limiting portion 310, the distance between the connecting rod 300 and the bottom wall of the accommodating cavity 210 is smaller than the distance between the connecting rod 300 and the bottom wall of the accommodating cavity 210 when the limiting member 500 is connected to the second limiting portion 320.
When the handle grip 100 is pressed by an external force towards the connecting rod 300, the handle grip 100 moves towards the direction approaching the accommodating cavity 210, the limiting piece 500 is separated from the first limiting part 310, the limitation of the limiting piece 500 on the connecting rod 300 is released, the connecting rod 300 moves towards the direction far away from the bottom wall of the accommodating cavity 210 under the action of the elastic force of the elastic piece 400, the handle grip 100 is driven to move and spring, when the limiting piece 500 is connected with the second limiting part 320, the acting force of the elastic piece 400 and the limiting piece 500 on the connecting rod 300 is balanced again, and the height of the handle grip 100 is kept unchanged. When an external force is applied again, the handle grip 100 moves in a direction approaching the accommodating cavity 210, the limiting member 500 is separated from the second limiting portion 320, the connecting rod 300 moves toward the bottom wall of the accommodating cavity 210, the elastic member 400 is continuously compressed under the action of the external force, when the limiting member 500 is connected to the first limiting portion 310 again, the external force is released, the acting force of the elastic member 400 and the limiting member 500 on the connecting rod 300 is balanced again, and the height of the handle grip 100 is kept unchanged.
In the mobile sub-machine 20 having the telescopic handle 10, the mounting box 200 is fixed on the housing 21 and is placed in a sealed space formed by the housing 21, and when the telescopic handle 10 is in an initial state, the top surface of the handle grip 100 is flush with the outer surface of the housing 21, and the telescopic is hidden in the housing 21. When the user presses the handle grip 100 and the pressing force reaches a certain degree, the handle grip 100 moves towards the direction close to the accommodating cavity 210, so as to drive the connecting rod 300 to move, so that the limiting piece 500 is separated from the first limiting portion 310, the handle grip 100 is sprung up under the action of the elastic piece 400 until the limiting piece 500 is connected to the second limiting portion 320, the acting force of the elastic piece 400 and the limiting piece 500 on the connecting rod 300 reaches balance again, and the height of the handle grip 100 remains unchanged. At this time, the handle grip 100 extends out of the surface of the housing 21, and the user can push and pull the mobile sub-unit 20 by holding the handle grip 100. When the operation is completed, the handle grip 100 may be pressed again, retracting the connecting rod 300 into the receiving cavity 210 so that the top surface of the handle grip 100 is flush with the outer surface of the housing 21, and the extension and retraction is hidden within the housing 21.
Through set up first spacing portion 310 and second spacing portion 320 respectively on connecting rod 300 along its axis direction, and hold the intracavity and set up and connect the elastic component 400 of connecting rod 300, make spacing piece 500 one end is connected install box 200, the other end is connected when first spacing portion 310 or second spacing portion 320, elastic component 400 and spacing piece 500 are right the effort of connecting rod 300 can reach the equilibrium, realized connecting rod 300 is relative install box 200 stationary state. By setting the handle grip 100 close to the accommodating movement, the limiting member 500 is separated from the first limiting member 310 or the second limiting member 320, so that the connecting rod 300 is ejected or retracted from the accommodating cavity 210 under the action of the elastic member 400, that is, the handle grip 100 is pressed, so that the handle grip 100 is ejected or retracted. When the telescopic handle 10 is arranged on other devices such as a movable air conditioner, a groove for the hand of a user to enter is not required, the integrity and the aesthetic property of the device are not damaged, and the handle 100 can be popped up by only pressing the handle 100, so that the user can hold the handle 100 and push and pull the device.
It may be known that, when the limiting member 500 is connected to the first limiting portion 310 and the acting forces of the elastic member 400 and the limiting member 500 on the connecting rod 300 can reach equilibrium, a pressing gap with a certain height exists between one end of the connecting rod 300 opposite to the handle grip 100 and the bottom wall of the accommodating cavity 210, so as to ensure that the connecting rod 300 has a space moving towards the bottom wall of the accommodating cavity 210, so that the limiting member 500 is separated from the first limiting portion 310, and ejection of the connecting rod 300 is achieved.
Referring to fig. 8 to 10, in an embodiment, a first chute 330 and a second chute 340 are respectively disposed on two sides of the first limiting portion 310 along the sliding direction of the connecting rod 300, one end of the first chute 330 and one end of the second chute 340, which are close to the handle 100, are communicated with the first limiting portion 310, the other end is communicated with the second limiting portion 320, when the limiting member 500 is separated from the first limiting portion 310, the limiting member 500 can slide along the first chute 330 to the second limiting portion 320, and when the limiting member 500 is separated from the second limiting portion 320, the limiting member 500 can slide along the second chute 340 to the first limiting portion 310.
When the limiting member 500 is disengaged from the first limiting portion 310 or the second limiting portion 320, the connecting rod 300 moves in the accommodating cavity 210, i.e. one end of the limiting member 500 connected to the connecting rod 300 moves relative to the connecting rod 300. The first sliding groove 330 and the second sliding groove 340 are respectively located at two sides of the first limiting portion 310, the first sliding groove 330 and the second sliding groove 340 are both communicated with the first limiting portion 310 and the second limiting portion 320, when the limiting piece 500 is separated from the first limiting portion 310, the limiting piece can slide to the second limiting portion 320 through the first sliding groove 330, and when the limiting piece 500 is separated from the second limiting portion 320, the limiting piece can slide to the first limiting portion 310 through the second sliding groove 340. The first sliding groove 330 and the second sliding groove 340 play a guiding role on the sliding of the limiting member 500, so as to ensure that the limiting member 500 can return to the second limiting portion 320/the first limiting portion 310 after being separated from the first limiting portion 310/the second limiting portion 320.
Specifically, the depth of the first limiting portion 310 is smaller than the depth of the first sliding groove 330 on one side thereof, and is larger than the depth of the second sliding groove 340 on one side thereof, the depth of the second limiting portion 320 is larger than the depth of the first sliding groove 330 on one side thereof, and is not larger than the depth of the second sliding groove 340 on one side thereof, and stepped surfaces formed by different depths enable the limiting member 500 to slide in the first limiting portion 310, the first sliding groove 330, the second limiting portion 320 and the second sliding groove 340 in a unidirectional circulating manner.
The first limiting portion 310, the first sliding groove 330, the second limiting portion 320 and the second sliding groove 340 are sequentially communicated circumferentially, when one end of the limiting member 500, which is connected with the connecting rod 300, is separated from the first limiting portion 310, the formed step surface blocks the limiting member 500 from sliding into the second sliding groove 340 from the first limiting portion 310 due to the deeper depth of one side of the second sliding groove 340 communicated with the second sliding groove 340, the first sliding groove 330 has shallower depth of one side of the first sliding groove 330, the limiting member 500 can slide into the first sliding groove 330, and the formed step surface blocks the limiting member 500 from sliding back into the first limiting portion 310. Similarly, when the limiting member 500 enters the first limiting portion 310 from the first sliding groove 330, the depth of the first sliding groove 330 at the side where the second limiting portion 320 is communicated is smaller than the depth of the second limiting portion 320, the limiting member 500 may slide into the second limiting portion 320, and the formed stepped surface may prevent the limiting member 500 from sliding back into the first sliding groove 330; when the limiting piece 500 enters the first limiting portion 310 from the second sliding groove 340, the depth of the second sliding groove 340 at one side of the first limiting portion 310 is smaller than that of the first limiting portion 310, the limiting piece 500 can slide into the first limiting portion 310, and the formed stepped surface can prevent the limiting piece 500 from sliding back into the second sliding groove 340.
Preferably, in order to achieve the smoothness of unidirectional circular sliding of the limiting member 500 in the first limiting portion 310, the first sliding groove 330, the second limiting portion 320, and the second sliding groove 340, the first limiting portion 310 and the second limiting portion 320 are concavely disposed in a direction facing away from the handle grip 100. When the connecting rod 300 is stationary relative to the mounting box 200, the limiting member 500 is located at the concave center of the first limiting portion 310 or the second limiting portion 320. On the one hand, the stability of the level training between the limiting piece 500 and the first limiting portion 310 or the second limiting portion 320 can be ensured, on the other hand, the inclined side wall or the arc side wall formed by the concave arrangement can play a guiding role, so that the transition between the first limiting portion 310, the first sliding groove 330, the second limiting portion 320 and the second sliding groove 340 of the limiting piece 500 is smoother.
Referring to fig. 6 and 7, in an embodiment, a stop protrusion 231 is disposed on an inner side wall of the receiving cavity 210 opposite to the limiting member 500, the stop protrusion 231 abuts against the limiting member 500, and when the limiting member 500 slides into the first sliding slot 330 or the second sliding slot 340, the limiting member 500 abuts against a bottom wall of the first sliding slot 330 or the second sliding slot 340.
When the limiting member 500 slides in the first sliding groove 330 relative to the connecting rod 300, if the speed of the elastic member 400 pushing against the connecting rod 300 is too high, the end of the limiting member 500 connected with the connecting rod 300 is easy to pop up from the first sliding groove 330; or when the limiting member 500 slides in the second sliding groove 340 relative to the connecting rod 300, if the external force pressing the handle grip 100 is too large, the moving speed of the connecting rod 300 toward the bottom wall of the accommodating cavity 210 is too fast, and the end of the limiting member 500 connected with the connecting rod 300 is easily ejected out of the second sliding groove 340. The inner sidewall of the accommodating cavity 210 opposite to the limiting member 500 is provided with a stop protrusion 231, and when the limiting member 500 slides into the first sliding groove 330 or the second sliding groove 340, the limiting member 500 abuts against the bottom wall of the first sliding groove 330 or the second sliding groove 340. On the one hand, the limiting member 500 may be limited in the depth direction of the first chute 330 and the second chute 340, so as to prevent the limiting member 500 from being ejected out of the first chute 330 or the second chute 340; on the other hand, when the limiting member 500 abuts against the bottom wall of the first sliding groove 330, the moving speed of the limiting member 500 in the accommodating cavity 210 may be reduced, so as to avoid increasing the impact between the parts when the connecting rod 300 pops out too fast.
