[0002] An elevator buffer is an elevator safety device that provides the last line of defense. It is installed in the elevator shaft pit, directly below the car and counterweight. When the elevator is moving up or down and exceeds the terminal floor (bottom or top floor) due to broken wire rope, traction friction, insufficient braking force of the brake, or control system failure, the buffer will act as a buffer to prevent the elevator car from directly hitting the bottom and protect the safety of passengers and equipment.

In order to increase the stability of the buffer, an auxiliary support structure is set on the outside of the buffer. However, the existing auxiliary support structure is generally directly fixed to the outside of the buffer, and its position and angle cannot be adapted and adjusted according to the space at the bottom of the elevator shaft. This makes it necessary to customize the buffer in advance according to the actual situation of the elevator shaft during installation, resulting in poor adaptability and thus increasing the limitations of the device.

[0020] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0021] Please see Figures 1 to 4 The present invention preferably provides the following technical solution: an elevator buffer, comprising a base 1, a buffer device 2 mounted on the upper surface of the base 1, the buffer device 2 comprising a cylinder 21 fixedly mounted on the upper surface of the base 1; further comprising a piston 22 slidably mounted in the cylinder 21, a top cover 23 fixedly mounted on the upper surface of the piston 22, a buffer spring 24 sleeved on the piston 22, and a fixing plate 25 fixedly mounted on the outer wall of the cylinder 21; one end of the buffer spring 24 is fixedly mounted on the bottom surface of the top cover 23, and the other end of the buffer spring 24 is fixedly mounted on the upper surface of the fixing plate 25; and a support device 3 mounted on the cylinder 21 for supporting the buffer device 2.
[0022] In this embodiment, the buffer device 2 is supported by the support device 3. During this process, the support device 3 can be adjusted so that it can be used in elevator shafts of different sizes without special customization. It has good adaptability and reduces the limitations of the device.
[0023] Specifically, during use, the staff fixes the base 1 to the inner bottom wall of the elevator shaft. Then, the staff adjusts the support device 3 to a suitable position, thereby supporting the buffer device 2 and improving the stability of the buffer device 2 during use.
[0024] It is worth noting that the buffer device 2 can cushion the elevator car when it falls rapidly, thereby reducing the probability of injury to people inside the elevator car.
[0025] This utility model uses a support device 3 to support the buffer device 2. During this process, the support device 3 can be adjusted, so it can be used in elevator shafts of different sizes without special customization, which has good adaptability and reduces the limitations of the device.
[0026] Furthermore, the lower end of the fixed plate 25 is provided with multiple rotating grooves 35, and the support device 3 includes a movable ring 31 sleeved on the outer wall of the cylinder 21, multiple rotating blocks 32 respectively rotatably disposed in multiple rotating grooves 35; it also includes multiple support legs 33 respectively fixed to the multiple rotating blocks 32, and multiple connecting rods 34 respectively rotatably disposed on the multiple support legs 33, with the ends of the multiple connecting rods 34 away from the support legs 33 fixed to the movable ring 31.
[0027] Combination Figure 1 , 2 As shown in Figure 3, when the staff needs to support the buffer device 2, the staff needs to slide the movable ring 31 downwards, which causes the support leg 33 to rotate outwards under the action of the connecting rod 34 and the movable ring 31. This causes the rotating block 32 to rotate outwards under the action of the support leg 33, so that the bottom surface of the support leg 33 abuts against the inner bottom wall of the elevator shaft, thereby supporting the buffer device 2. During this process, the staff can adjust the rotation range of the support leg 33 by sliding the movable ring 31, so that it can be used in elevator shafts of different sizes without special customization, with good adaptability, thus reducing the limitations of the device.
[0028] Furthermore, a rotating seat 4 is fitted on the outer wall of each of the multiple support legs 33, and the ends of the multiple connecting rods 34 away from the movable ring 31 are rotatably connected to the rotating seat 4.
[0029] like Figure 2 , 3 As shown, when the support leg 33 rotates outward under the action of the connecting rod 34 and the movable ring 31, the connecting rod 34 and the support leg 33 rotate relative to the movable ring 31. During this process, the rotating seat 4 limits the connecting rod 34, thereby reducing the probability of collision when the connecting rod 34 and the support leg 33 rotate relative to each other, thus improving the stability of the device.
[0030] Furthermore, the movable ring 31 is threadedly connected to the cylinder body 21, and an annular groove 5 is provided on the outer wall of the movable ring 31. An annular block 51 is rotatably arranged in the annular groove 5. A rotating groove 52 is circumferentially arranged on the outer wall of the annular block 51, and the ends of multiple connecting rods 34 away from the rotating seat 4 are rotatably connected to the rotating groove 52.
[0031] like Figure 2 , 3As shown in Figure 4, when the operator needs to move the movable ring 31, the operator needs to rotate the movable ring 31. Since the movable ring 31 is threadedly connected to the cylinder 21, the movable ring 31 moves up and down. In this process, the threaded connection between the movable ring 31 and the cylinder 21 reduces the difficulty for the operator to move the movable ring 31 up and down. In addition, the threaded connection between the movable ring 31 and the cylinder 21 also reduces the difficulty for the operator to fix the movable ring 31 after adjustment. Furthermore, when the movable ring 31 rotates, the annular block 51 rotates relative to the movable ring 31. When the connecting rod 34 rotates, the connecting rod 34 rotates within the rotating groove 52. In this process, the difficulty for the operator to rotate the movable ring 31 is reduced, thereby reducing the difficulty of the operator's work.
[0032] The lower end of the support leg 33 is rotatably provided with a rotating seat 6, and the bottom surface of the rotating seat 6 is fixedly provided with a support plate 61; the upper surface of the base 1 is provided with a plurality of first fixing holes 62, and the upper surface of the support plate 61 is provided with a plurality of second fixing holes 63.
[0033] like Figure 1 , 2 As shown in Figure 3, when the support leg 33 rotates, the rotating seat 6 and the support plate 61 rotate under the action of the support leg 33. During this process, after adjustment, the bottom surface of the support plate 61 abuts against the inner bottom wall of the elevator shaft. At this time, the workers fix the support plate 61 and the base 1 in the elevator shaft using expansion bolts and the first fixing hole 62 and the second fixing hole 63, respectively. During this process, the support plate 61 increases the contact area between the support leg 33 and the inner bottom wall of the elevator shaft, thereby improving the stability of the support device 3.
[0034] Multiple threaded holes 7 are arrayed on the outer wall of the support leg 33, and a fixing bolt 71 is threaded through the outer wall of the rotating seat 4, and the fixing bolt 71 is rotatably connected to the threaded hole 7.
[0035] like Figure 1 , 2 As shown in Figure 3, the operator can slide the rotating seat 4. After sliding, the operator can fix it with the fixing bolt 71. During this process, the sliding rotating seat 4 adjusts the distance between the movable ring 31 and the support leg 33, so that the support device 3 can work in elevator shafts of different sizes, thereby reducing the limitations of the device.
[0036] A fixing member 8 is fitted on the outer wall of the cylinder body 21. The fixing member 8 is slidably connected to the cylinder body 21 and is fixed to the movable ring 31.
[0037] like Figure 1 , 2 As shown, the fixing part 8 reduces the difficulty for the staff to rotate the movable ring 31, thereby reducing the difficulty of the staff's work.
[0038] A buffer element 9 is fixedly installed on the upper surface of the top cover 23. The buffer element 9 is made of polyurethane material.
[0039] like Figure 1 As shown, the buffer component 9 made of polyurethane material further improves the buffering effect of the buffer device 2, thereby further reducing the probability of injury to people inside the elevator car.
[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit method, or by using a bolt connection, etc.
[0041] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
