Description

Technical Field

[0001] The utility model relates to the technical field of elevator car handrails, and particularly relates to a practical elevator car handrail device. Background Technique

[0002] During the elevator's ascending and descending process, passengers may become unbalanced due to the movement of the car. The handrail can provide additional support to prevent falls. It guides passengers to move towards the elevator door when the elevator stops, improving the riding efficiency. The handrail increases the psychological sense of security of passengers, which is particularly important for passengers prone to anxiety. The elderly, the disabled and other people with mobility difficulties can move more easily by holding the handrail. The handrail design can enhance the interior decoration effect of the elevator.

[0003] When the applicant was conducting this application, after retrieval, it was found that the Chinese patent disclosed "A handrail device for an elevator car", with the application number "CN201920855934.1". This patent mainly includes a car wall, a groove is provided on the car wall, a vertical partition is fixed in the groove, and the partition divides the groove into a first installation groove and a second installation groove; the handrail device includes a handrail rod arranged in the second installation groove, both ends of the handrail rod are vertically connected with sliding rods, both sliding rods penetrate through the partition in the horizontal direction, a connecting plate is arranged between the ends of the two sliding rods located in the first installation groove, a slider vertically penetrating through the support plate is arranged at the bottom of the connecting plate, and the bottom of the slider is fixedly connected with the telescopic end of the electric telescopic rod. The support plate is provided with a chute for the slider to penetrate through and for guiding the sliding of the slider. A handrail device for an elevator car of the utility model can store the handrail rod in the groove of the car wall to avoid the handrail rod occupying the internal space of the car.

The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0023] Embodiment:

[0024] Referring to Figures 1 to 5 , an embodiment of a practical elevator car handrail device of the present utility model includes an installation mechanism 1. A start button 2 is fixedly connected to the right part of the front side of the installation mechanism 1. The start button 2 is fixedly connected to a retraction button 3. A retracting mechanism 5 is fixedly connected inside the installation mechanism 1. A rotating mechanism 4 is fixedly connected to the front side of the retracting mechanism 5. When retracting, press the start button 2, and the retracting mechanism 5 causes the rotating mechanism 4 to retract. Rotate the rotating mechanism 4 to retract it into the installation mechanism 1. The rotating mechanism 4 can control the height of the handrail 401.

[0025] The installation mechanism 1 includes an elevator car 101, an armrest recovery groove 102, a shielding cover installation groove 103, an installation mechanism installation groove 104, a recovery groove 105, and a shielding cover 106. The shielding cover installation groove 103 is provided at the lower front side of the elevator car 101. The shielding cover 106 is fixedly connected inside the shielding cover installation groove 103. The installation mechanism installation groove 104 is provided on both the left and right sides of the lower side of the elevator car 101. The recovery groove 105 is provided above the shielding cover installation groove 103. The armrest recovery groove 102 is provided above the recovery groove 105. The shielding cover 106 provides shielding for the contraction mechanism 5, making the device more aesthetically pleasing. The recovery groove 105 and the armrest recovery groove 102 are used to recover the rotating mechanism 4, and the installation mechanism installation groove 104 is used to install the contraction mechanism 5.

[0026] The contraction mechanism 5 includes a hydraulic rod 501, a sliding block 502, a connecting plate 503, a sliding groove 504, and a support plate 505. The support plate 505 is fixedly connected to the front side of the bottom of the installation mechanism installation groove 104. The hydraulic rod 501 is fixedly connected to the rear side of the installation mechanism installation groove 104. The sliding block 502 is fixedly connected to the telescopic end of the hydraulic rod 501. The connecting plate 503 is fixedly connected to the upper end of the sliding block 502. The sliding groove 504 is provided in the middle of the upper side of the support plate 505. The sliding block 502 is slidably connected inside the sliding groove 504. When contracting, the hydraulic rod 501 is activated to drive the sliding block 502 to move forward along the sliding groove 504, so that the support plate 505 pushes the rotating mechanism 4 forward.

[0027] The rotating mechanism 4 includes an armrest 401, a fixed rod 402, a rotating groove 403, a fixed groove 404, a rotating protrusion 405, a fixed protrusion 406, and a rotating rod 407. The fixed rod 402 is fixedly connected to the front side of the connecting plate 503. The rotating groove 403 is provided at the left front end of the fixed rod 402. The fixed groove 404 is provided on the right side of the rotating groove 403. The fixed protrusion 406 is rotatably connected inside the fixed groove 404. The rotating protrusion 405 is fixedly connected to the left side of the fixed protrusion 406. The rotating rod 407 is fixedly connected to the left side of the rotating protrusion 405. The armrest 401 is fixedly connected to the front side of the rotating rod 407. The rotating protrusion 405 is rotatably connected inside the rotating groove 403. The fixed rod 402 and the rotating rod 407 are slidably connected in the middle of the recovery groove 105. When changing the height, the armrest 401 is pushed, so that the armrest 401 drives the rotating rod 407 to rotate. At this time, the rotating protrusion 405 and the fixed protrusion 406 rotate in the rotating groove 403 and the fixed groove 404. The fixed groove 404 and the fixed protrusion 406 prevent the fixed rod 402 and the rotating rod 407 from detaching. The fixed rod 402 fixes the rotating mechanism 4 until the armrest 401 is pulled to the appropriate position and stopped.

[0028] Working principle: When using the armrest device, first pull the armrest 401 to take it out of the armrest recovery groove 102, and then press the start button 2. The start button 2 activates the hydraulic rod 501, and the hydraulic rod 501 drives the sliding block 502 to move forward along the chute 504, so that the support plate 505 pushes the fixed rod 402 forward along the recovery groove 105. When it reaches the position, the hydraulic rod 501 automatically stops. Finally, push the armrest 401, so that the armrest 401 drives the rotating rod 407 to rotate. At this time, the rotating protrusion 405 and the fixed protrusion 406 rotate in the rotating groove 403 and the fixed groove 404. The fixed groove 404 and the fixed protrusion 406 prevent the fixed rod 402 and the rotating rod 407 from separating. The fixed rod 402 fixes the rotating mechanism 4 until the appropriate position to stop pulling the armrest 401. When the inside of the elevator car 101 is relatively small, press the retraction button 3. The hydraulic rod 501 pulls the fixed rod 402 to retract. After reaching the position, push the armrest 401 upward, and the rotating rod 407 rotates in the recovery groove 105, so that the armrest 401 retracts into the armrest recovery groove 102.

[0029] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
