Description
Technical Field
[0001] The utility model relates to the technical field of elevator protection devices, in particular to a foldable multifunctional car integrated elevator protection device. Background Art
[0002] The elevator car is a box-shaped space used to carry and transport people and materials. The elevator car is generally composed of main components such as the car bottom, car walls, car top, and car doors. Elevators are used in residential buildings in residential communities, commercial office buildings, and public construction buildings. As a common equipment in life, elevators are frequently used.
[0003] For example, the public document with application number 202122952995.X discloses a foldable multifunctional safety handrail device for an elevator car. The utility model directly rotates the handle downward and pulls the handle out from the groove in the car wall for the user to hold it directly. The concave structure in the middle of the handle fits the human hand more closely. When the elevator is moving up and down, the elderly can grab the handle. Since the position of the handle can be rotated and adjusted according to the elderly's holding height, the spring inside the handle can also be pulled back and forth to prevent the elderly from falling and getting injured due to loss of grip. However, the handle supported by the grip cannot be effectively fixed when it is rotated and removed for use. The shaft of the handle adopts a rotating shaft and a long cylindrical rod with rotatable cylindrical bodies at both ends. If it is not fixed in the unfolded state, the handle will swing when the car vibrates. At this time, not only can the elderly not be supported and helped, but it is also very easy for the elderly to fall, and there is a certain risk in using it.
[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a foldable multifunctional car integrated elevator protection device is proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figure 1-Figure 2 As shown, a foldable multifunctional integrated elevator car protection device includes a car wall 1, a storage cavity 2 is opened on the surface of the car wall 1, and fixing rings 3 are fixedly installed at both left and right ends of the lower inner surface of the storage cavity 2, and positioning holes 301 are opened at right angles above and in front of the opposite side of the surface of the fixing ring 3, and a shaft rod 4 is rotatably arranged in the middle of the opposite side of the surface of the fixing ring 3 through a bearing, a handle 5 is fixedly arranged on the surface of the shaft rod 4, and a locking mechanism 6 is arranged on the inner side of the handle 5.
[0024] Through the above technical solution, after the handle 5 is rotated and unfolded outward, it can be used as a handrail to hold, so as to prevent the car from shaking and causing people to fall. At the same time, after the elevator falls, the escape passage opened on the top of the car is too high, and the handle 5 can also be used as a stepping point for climbing, achieving the effect of one thing with multiple uses, and the storage cavity 2 provides space for the handle 5 to be retracted, so as to prevent the handle 5 from protruding outward and causing bumps and injuries to passengers.
[0025] Furthermore, the locking mechanism 6 includes a horizontal frame 601 fixedly installed in the middle of the surface of the handle 5, a thrust spring 602 is fixedly installed below the surface of the horizontal frame 601, a movable plate 603 is fixedly provided at the bottom end of the thrust spring 602, and the locking mechanism 6 also includes a pull rod 604 rotatably provided at both ends of the movable plate 603, a locking pin 605 is rotatably provided at the lower end of the pull rod 604, and the opposite end of the locking pin 605 slides through the bottom of the handle 5 and is located in the positioning hole 301.
[0026] By adopting the above technical solution, the movable plate 603 is pushed upward, the thrust spring 602 is compressed, and at the same time, the movable plate 603 pulls the locking pin 605 to move toward the middle through the pull rod 604 and moves out of the positioning hole 301, and the handle 5 can be rotated freely at this time;
[0027] When the handle 5 is retracted into the storage chamber 2, the lock pin 605 is aligned with the upper positioning hole 301, and the thrust spring 602 pushes the movable plate 603 downward, thereby pushing the lock pin 605 into the upper positioning hole 301 through the pull rod 604, so that the handle 5 can be stably stored;
[0028] When the handle 5 is rotated for use, the locking pin 605 is aligned with the front positioning hole 301, and the locking pin 605 is inserted into the front positioning hole 301 to fix the handle 5 in a horizontal state, thereby preventing the handle 5 from rotating unsteadily when it is manually held for support.
[0029] like Figure 3-Figure 4 As shown, two movable grooves 7 are symmetrically provided along the center at the lower part of the inner surface of the storage cavity 2, and guide grooves 8 are provided on the left and right sides of the inner surface of the movable groove 7. A telescopic spring 9 is fixedly provided at the bottom of the inner surface of the guide groove 8. The upper end of the telescopic spring 9 is located inside the guide groove 8 and a limiting guide block 10 is fixedly provided. The limiting guide block 10 slides in contact with the inner surface of the guide groove 8.
[0030] By adopting the above technical solution, the limiting guide blocks 10 are inserted into the guide grooves 8 on both sides, which can make the movement of the sliding seat 11 more stable and prevent the sliding seat 11 from slipping;
[0031] After the handle 5 is used and the locking mechanism 6 is unlocked, the telescopic spring 9 can push the sliding seat 11 and the support rod 12 upward in the opposite direction through the limiting guide block 10, so that the handle 5 is automatically retracted.
[0032] Furthermore, a sliding seat 11 is fixedly provided in the middle of the opposite end of the limiting guide block 10 and is located inside the movable groove 7. The sliding seat 11 is slidably connected to the inner surface of the movable groove 7. A support rod 12 is rotatably provided on the surface of the sliding seat 11 through a rotating shaft. A fixed seat 13 is rotatably provided on the upper end of the support rod 12, and the fixed seat 13 is fixedly connected to the handle 5.
[0033] By adopting the above technical solution, the bottom end of the movable groove 7 supports the handle 5 through the sliding seat 11 and the support rod 12, so that the support stability of the handle 5 is higher when it is pressed downward, and the use strength of the handle 5 is greatly improved.
[0034] Working principle: When using the foldable multifunctional integrated elevator protection device for the car, first, when using the handle 5, the movable plate 603 is pushed upward, the thrust spring 602 is compressed, and the movable plate 603 will pull the locking pin 605 to move toward the middle through the pull rod 604 and move out of the positioning hole 301. At this time, the handle 5 can rotate freely, and the handle 5 is pulled to rotate and move out of the storage cavity 2. After maintaining a horizontal state, the locking pin 605 is aligned with the front positioning hole 301, and the thrust spring 602 will push the movable plate 603 to move downward, thereby pushing the locking pin 605 to insert into the corresponding positioning hole 301 through the pull rod 604. The locking pin 605 will be inserted into the front positioning hole 301, so that the handle 5 is fixed in a horizontal state for use. At the same time, when the handle 5 is rotated to unfold outward, the sliding seat 11 will be pushed downward through the fixed seat 13 and the support rod 12, and the sliding seat 11 will be moved to the bottom of the movable groove 7 under the limit of the guide groove 8 and the limit guide block 10. The handle 5 is then supported by the sliding seat 11 and the support rod 12 at the bottom of the movable groove 7, so that the support stability of the handle 5 is higher when the handle 5 is pressed downward. The unfolded handle 5 can be used as a support point for holding, or as a stepping and climbing point, and can also be used to place or stack objects. After use, the movable plate 603 is moved upward again to release the handle 5 from being locked. After the locking mechanism 6 is unlocked, the sliding seat 11 and the support rod 12 can be pushed upward in the opposite direction through the limiting guide block 10, so that the handle 5 automatically rotates upward and is retracted into the storage chamber 2. After the handle 5 is located in the storage chamber 2 and remains vertical, the locking pin 605 is aligned with the upper positioning hole 301, and the thrust spring 602 will push the movable plate 603 to move downward, thereby pushing the locking pin 605 through the pull rod 604 to insert into the upper positioning hole 301, so that the handle 5 can be stably stored. This is the working principle of the foldable multifunctional car integrated elevator protection device.
