During installation, it will be equipped with a shock-absorbing mechanism to improve the stability of the freight elevator, ensure the smooth operation of the freight elevator, reduce vibration and noise, extend the service life of the equipment, and protect the safety of goods.

[0003] For example, publication number CN221857413U discloses a shock-absorbing mechanism for a freight elevator car, comprising a freight elevator car body and a support plate, the outer wall of the freight elevator car body being fixedly connected to a first support block, the inner wall of the first support block being movably connected to a first connecting piece, the bottom of the freight elevator car body being fixedly connected to a piston rod, the outer wall of the piston rod being sleeved with a first shock-absorbing spring, and the bottom of the freight elevator car body being fixedly connected to an extrusion block near the outer side of the piston rod.

[0004] However, in the existing technology, the rebound of the shock-absorbing structure will produce a certain amount of vibration, making it difficult for people standing on it to maintain a stable standing posture. In addition, the deformation and movement of different parts of the shock-absorbing structure during the rebound process can easily cause the center of gravity of the people to shift. When the people cannot adjust their center of gravity in time to adapt to this change, they are prone to falling. Especially when people are walking, carrying goods or performing other complex movements, the shift of the center of gravity is more likely to cause danger. Utility Model Content

Especially when the personnel are walking, carrying goods or performing other complex actions, the shift of the center of gravity is more likely to cause danger. A shock-absorbing mechanism for a freight elevator car is proposed.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a shock absorbing mechanism for a freight elevator car, comprising a bottom plate and a contact plate, wherein the contact plate is located above the bottom plate, a balancing assembly is fixedly mounted on the lower surface of the contact plate, and a reinforcement assembly is fixedly mounted on the upper surface of the bottom plate;

DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model provides a shock absorbing mechanism for a freight elevator car, comprising a base plate 1 and a contact plate 2. The contact plate 2 is located above the base plate 1. A balancing assembly 4 is fixedly mounted on the lower surface of the contact plate 2. A reinforcement assembly 3 is fixedly mounted on the upper surface of the base plate 1.

[0025] The balancing assembly 4 includes a positioning block 43, a connector 45, a first connecting rod 41 and a second connecting rod 44. The positioning block 43 is fixedly installed at the four corners of the contact plate 2, and the connector 45 is fixedly installed at the center of the contact plate 2. A support rod 46 is fixedly connected between the positioning block 43 and the connector 45. A rectangular frame 42 is fixedly connected between the four positioning blocks 43. The first connecting rod 41 is fixedly installed on the outer wall of the rectangular frame 42. The second connecting rod 44 is fixedly installed on the outer wall of the rectangular frame 42. A vertical rod 47 is fixedly installed at the bottom of the positioning block 43 and the bottom of the connector 45. A limiting plate 49 is rotatably installed on the outer wall of the vertical rod 47.

[0026] The following describes in detail the specific configuration and function of this embodiment. The contact plate 2 is fixedly connected to the car, the base plate 1 is used to connect to the freight elevator, and the balancing assembly 4 and the reinforcement assembly 3 are located between the base plate 1 and the contact plate 2. When people enter and exit the car, the weight of the human body will generate a downward pressure on the car, and the pressure is transmitted to the reinforcement assembly 3 through the balancing assembly 4.

[0027] The balancing assembly 4 mainly consists of a rectangular frame 42 of a rectangular structure, a first connecting rod 41, and a cross-structured support rod 46 and a second connecting rod 44. The second connecting rod 44 is located on the diagonal line, which reinforces the structure of the entire rectangular frame 42. The positioning blocks 43 are installed at the four corners of the contact plate 2, and the connector 45 is fixedly installed at the center of the contact plate 2. When the contact plate 2 is subjected to pressure, the pressure can be quickly transferred to the other positioning blocks 43, thereby dispersing the pressure. At this time, the problem of car shaking can be avoided, the center of gravity of the personnel can be prevented from shifting, and the stability of the personnel when entering and exiting the car can be improved.

[0028] The positioning block 43 and the vertical rod 47 at the bottom of the connector 45 are both slidably connected in the reinforcement component 3. When subjected to pressure, the vertical rod 47 will move downward into the reinforcement component 3. During this process, the sealing plug 48 will move in the damper 32, thereby achieving the purpose of shock absorption. After the shock absorption is completed, the rebound of the shock-absorbing spring 35 will bounce the positioning block 43 up again.

[0029] Example 2: Figure 2 、 Figure 3 and Figure 4As shown, the reinforcement component 3 includes an inclined rod 31 and a damper 32, one end of the inclined rod 31 is fixedly connected to the bottom of the damper 32, one end of the vertical rod 47 is inserted into the inside of the damper 32, and the lower surface of the limiting plate 49 is fixedly connected to the shock-absorbing spring 35. A threaded groove 33 is provided on the outer wall of the damper 32, and a movable plate 34 is threadedly connected to the outer wall of the damper 32 through the threaded groove 33. One end of the shock-absorbing spring 35 is fixedly connected to the upper surface of the movable plate 34, and the shock-absorbing spring 35 is sleeved on the outer wall of the damper 32. A sealing plug 48 is fixedly installed on the outer wall of the vertical rod 47, and the sealing plug 48 is slidably connected to the inner wall of the damper 32.

[0030] The effect achieved by the entire embodiment is that the damper 32 and the shock-absorbing spring 35 are both existing technologies and will not be described in detail here. The vertical rod 47 is connected to the damper 32 through the sealing plug 48. The damper 32 is fixedly connected to the oblique rod 31. The oblique rod 31 is fixedly mounted on the upper surface of the base plate 1 in a cross structure to ensure the structural stability of the reinforcement assembly 3. The oblique rod 31 not only improves the structural strength of the base plate 1, but also ensures the stability of the damper 32.

[0031] A threaded groove 33 is provided on the outer surface of the damper 32, and the threaded groove 33 is mainly used to adjust the position of the movable piece 34. During later maintenance, the vertical rod 47 can be separated from the damper 32 by rotating the movable piece 34, which reduces the difficulty of installation and disassembly. The limit piece 49 is rotatably installed on the vertical rod 47 and will not affect the rotation of the movable piece 34.

[0032] The device is used in conjunction with its working principle: When in use, the contact plate 2 is fixedly connected to the car, and the bottom plate 1 is used to connect to the freight elevator. When people enter and exit the car, the weight of their bodies will exert a downward pressure on the car. The pressure is transmitted to the reinforcement component 3 through the balancing component 4. When the contact plate 2 is under pressure, the pressure can be quickly transmitted to the other positioning blocks 43.

[0033] The vertical rod 47 will move downward into the reinforcement component 3. During this process, the sealing plug 48 will move in the damper 32, thereby achieving the purpose of shock absorption. After the shock absorption is completed, the rebound of the shock-absorbing spring 35 will bounce the positioning block 43 up again. During later maintenance, the vertical rod 47 can be separated from the damper 32 by rotating the movable piece 34.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
