A mechanical elastic buffer connector

Abstract

This utility model relates to the field of high-altitude construction technology and discloses a mechanical elastic buffer connection seat, including a load-bearing connection seat. The top of the load-bearing connection seat has a mounting groove, and a buffer mechanism is installed inside the mounting groove. The buffer mechanism includes a fixed cylinder, which is fixedly installed inside the mounting groove. A contact rod extends from the top of the fixed cylinder, and a rubber head is fixedly installed at the top of the contact rod, while an insertion rod is fixedly installed at the bottom of the contact rod. This utility model utilizes the sliding of the contact plate and rubber pad inside the fixed cylinder to compress hydraulic oil into the receiving shell. The hydraulic oil flows through a flow hole, generating resistance that converts mechanical energy into heat energy, thus providing a buffering and energy dissipation effect. This prevents the lifting platform from shaking, which could lead to material scattering and collapse, maintaining the stability of the lifting platform. Furthermore, in conjunction with a first spring, the contact plate can be reset through elastic contraction after the lifting platform returns to its original position.

Description

Technical Field

[0001] This utility model relates to the field of high-altitude construction technology, specifically a mechanical elastic buffer connection seat. Background Technology

[0002] Aerial work platforms are specialized equipment used for high-altitude operations. They are widely used in construction, municipal maintenance, warehousing and logistics, power maintenance, and other fields. They can safely and efficiently transport personnel, tools, and materials to different heights. The basic structure of an aerial work platform includes a power system, lifting mechanism, work platform, control system, and safety devices. It solves the efficiency and safety problems of high-altitude operations through mechanization.

[0003] An existing patent (publication number: CN220467244U) discloses a construction machinery material hoist. This utility model, through the setting of the force-applying structure, can drive the baffle plate to move forward inside the fixed box, thereby conveniently blocking the gap between the material box and the floor, preventing materials or small tools from falling through the gap, thus bringing a certain degree of safety to the workers. At the same time, through the threaded connection between the screw sleeve and the screw rod, the connecting plate and the push plate can be driven to move forward, thereby facilitating the automatic ejection of materials inside the material box, making it convenient for workers to retrieve materials.

[0004] To address the aforementioned issues, while existing patents have proposed solutions that can conceal gaps through the use of components such as baffles, in actual use, when the lifting platform in the elevator reaches its lowest point, it shakes due to inertia and impact, causing materials to scatter or even collapse. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problem in the prior art that when the lifting platform in the elevator reaches the bottom, it will shake due to inertia and collision, causing materials to scatter or even collapse.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mechanical elastic buffer connection seat includes a load-bearing connection seat, the top of which is provided with a mounting groove, and a buffer mechanism is provided inside the mounting groove.

[0009] The buffer mechanism includes a fixed cylinder, which is fixedly installed inside the placement groove. An abutment rod extends from the top of the fixed cylinder. A rubber head is fixedly installed at the top of the abutment rod, and an insertion rod is fixedly installed at the bottom of the abutment rod. An abutment plate is fixedly installed at the bottom of the insertion rod, and a rubber pad is embedded at the bottom of the abutment plate. A first spring is sleeved on the outside of the insertion rod.

[0010] As a further improvement of this utility model: a storage shell is fixedly installed on the outer wall of the fixed cylinder, and flow holes are opened at corresponding positions of the storage shell and the fixed cylinder.

[0011] As a further improvement of this utility model: the inside of the storage shell is provided with a storage groove, and a flow guide block is embedded inside the storage groove.

[0012] As a further improvement of this utility model: the contact plate and the fixed cylinder form a sliding structure, and the contact plate is bonded to the rubber pad.

[0013] As a further improvement of this utility model: the fixed cylinder and the abutment rod form a sliding structure, and the fixed cylinder communicates with the storage shell through the flow hole.

[0014] As a further improvement of this utility model: a connecting plate is fixedly installed on the outer wall of the abutment rod, and an elastic mechanism is provided on one side of the connecting plate.

[0015] As a further embodiment of this utility model: the elastic mechanism includes a fixed shell, which is fixedly installed on one side of the fixed cylinder inside the placement groove, and a buffer block protrudes from the inside of the fixed shell.

[0016] As a further improvement of this utility model: a limiting plate is fixedly installed at the bottom end of the buffer block, and a sealing gasket is embedded at the bottom end of the limiting plate.

[0017] As a further improvement of this utility model: a through hole is provided at the bottom of the inner side of the fixed shell, and a limiting rod extends through the through hole. A second spring is sleeved on the outside of one end of the limiting rod that extends through the through hole.

[0018] As a further improvement of this utility model: the limiting plate is bonded to the sealing gasket, and the limiting plate and the fixed shell form a sliding structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model uses a contact plate and a rubber pad to slide inside the fixed cylinder, thereby squeezing hydraulic oil into the receiving shell. The hydraulic oil flows through the flow hole, which can generate a certain resistance to convert mechanical energy into heat energy, playing a certain role in buffering and energy dissipation, preventing the lifting platform from shaking and causing materials to scatter and collapse, thus maintaining the stability of the lifting platform. In addition, with the cooperation of the first spring, the contact plate can be reset through elastic contraction after the lifting platform is reset.

[0021] 2. This utility model uses a fixed shell, buffer block, limiting plate and sealing gasket to form a piston movement, which further achieves the buffering and energy dissipation effect. With the help of the through hole, limiting rod and second spring, the buffer block can be reset when the lifting platform resets after being compressed and displaced. The through hole allows gas to flow, which prevents the internal air pressure from being too high and causing the buffer block to be unable to move, thus failing to achieve the energy dissipation effect. The connecting plate makes the buffer mechanism and the elastic mechanism into one unit, which can maintain the smooth effect of the lifting platform falling. Attached Figure Description

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1

[0032] Please see Figures 1-3 This is the first embodiment of the present invention.

[0033] This embodiment provides a mechanical elastic buffer connection seat, including a bearing connection seat 1, a mounting groove 2 is provided at the top of the bearing connection seat 1, and a buffer mechanism 3 is provided inside the mounting groove 2;

[0034] The buffer mechanism 3 includes a fixed cylinder 301, which is fixedly installed inside the mounting groove 2. A contact rod 302 extends from the top of the fixed cylinder 301. A rubber head 303 is fixedly installed at the top of the contact rod 302. An insertion rod 304 is fixedly installed at the bottom of the contact rod 302. A contact plate 305 is fixedly installed at the bottom of the insertion rod 304. A rubber pad 306 is embedded at the bottom of the contact plate 305. A first spring 307 is sleeved on the outside of the insertion rod 304.

[0035] Specifically, a storage shell 308 is fixedly installed on the outer wall of the fixed cylinder 301, and a flow hole 309 is opened at the corresponding position of the storage shell 308 and the fixed cylinder 301.

[0036] Furthermore, through the flow hole 309, when under pressure, the hydraulic oil inside the fixed cylinder 301 can enter the receiving shell 308. Due to the viscosity of the hydraulic oil and the flow resistance in the flow hole 309, the impact force is consumed, thus achieving a buffering effect.

[0037] Specifically, the storage shell 308 has a storage groove 310 inside, and a flow guide block 311 is embedded inside the storage groove 310.

[0038] Furthermore, when the contact plate 305 is restored, hydraulic oil is drawn into the fixed cylinder 301 and then flows through the guide block 311 of the inclined structure to facilitate the flow of hydraulic oil.

[0039] Specifically, the contact plate 305 and the fixed cylinder 301 form a sliding structure, and the contact plate 305 is bonded to the rubber pad 306.

[0040] Furthermore, the adhesive connection between the contact plate 305 and the rubber pad 306 can improve the sealing of the contact plate 305 during displacement, thereby enabling the hydraulic oil to flow.

[0041] Specifically, a sliding structure is formed between the fixed cylinder 301 and the abutment rod 302, and the fixed cylinder 301 is connected to the storage shell 308 through the flow hole 309.

[0042] Furthermore, by limiting the contact rod 302 with the fixed cylinder 301, the stability of the contact rod 302 during displacement can be maintained, and the swaying and deviation can be avoided.

[0043] In use, the bearing connecting seat 1 is fixed to the bottom of the lifting frame. When the upgrading platform descends, the bottom faces the mounting groove 2 and abuts the rubber head 303, thereby squeezing the contact rod 302 to slide along the fixed cylinder 301, allowing the inserting rod 304 to move, and causing the contact plate 305 to drive the first spring 307 to stretch. The rubber pad 306 improves the airtightness and facilitates the squeezing of hydraulic oil through the flow hole 309 into the storage groove 310 of the storage shell 308, which plays a buffering role. When the lifting platform rises, the elastic contraction of the first spring 307 can reset the contact plate 305, thereby extracting the hydraulic oil inside the storage shell 308 and resetting it. The guide block 311 facilitates the flow of hydraulic oil.

[0044] In summary, the first spring 307 is fixed at one end to the top of the inside of the fixed cylinder 301 and at the other end to the contact plate 305. This allows hydraulic oil to flow through the flow hole 309 when the contact rod 302 is subjected to pressure from the lifting platform. This converts mechanical energy into heat energy and provides a certain buffering effect, preventing the lifting platform from vibrating and shaking, which could cause the internal materials to become scattered. In conjunction with the rubber head 303, it prevents the lifting platform from colliding with the contact rod 302, thus providing a protective effect.

[0045] Example 2

[0046] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0047] Specifically, a connecting plate 4 is fixedly installed on the outer wall of the abutment rod 302, and an elastic mechanism 5 is provided on one side of the connecting plate 4.

[0048] Furthermore, with the cooperation of the elastic mechanism 5, a buffering effect is further achieved when the lifting platform falls.

[0049] Specifically, the elastic mechanism 5 includes a fixed shell 501, which is fixedly installed on one side of the fixed cylinder 301 inside the placement groove 2, and a buffer block 502 protrudes from the inside of the fixed shell 501.

[0050] Furthermore, the top of the buffer block 502 is bonded with a rubber layer or flexible material to prevent collisions when the lifting platform descends.

[0051] Specifically, a limiting plate 503 is fixedly installed at the bottom of the buffer block 502, and a sealing gasket 504 is embedded at the bottom of the limiting plate 503.

[0052] Furthermore, the limiting plate 503, through the adhesive sealing gasket 504, can form a piston movement when the buffer block 502 slides inside the fixed shell 501, thereby improving the stability of the sliding process and playing a certain buffering effect.

[0053] Specifically, a through hole 505 is provided at the bottom of the interior of the fixed shell 501, a limit rod 506 extends through the through hole 505, and a second spring 507 is sleeved on the outside of one end of the limit rod 506 that extends through the through hole 505.

[0054] Furthermore, a second spring 507 is sleeved on the outside of the limiting rod 506 fixed by the limiting plate 503, and slides along the through hole 505 during the sliding process of the limiting plate 503, so that the second spring 507 can elastically expand and contract to achieve the energy dissipation effect and avoid bending and twisting.

[0055] Specifically, the limiting plate 503 is bonded to the sealing gasket 504, and the limiting plate 503 and the fixed shell 501 form a sliding structure.

[0056] Furthermore, the airtightness is improved by the sealing gasket 504, thereby forming piston movement. Gas flows slowly through the gap between the through hole 505 and the limit rod 506, thereby preventing excessive internal air pressure from causing the limit plate 503 to be unable to move.

[0057] During use, the bottom of the lifting platform simultaneously abuts against the buffer block 502, allowing the limiting plate 503 and the sealing gasket 504 to slide along the fixed shell 501. This, combined with the gap between the limiting rod 506 and the through hole 505, allows gas to flow slowly, thereby forming a piston movement, which further buffers and dissipates energy. In conjunction with the second spring 507 outside the limiting rod 506, the lifting platform can push the limiting plate 503 to reset the buffer block 502 after it rises.

[0058] In summary, the piston movement formed by the cooperation of the fixed shell 501 and the buffer block 502 further buffers the material loaded on the lifting platform, preventing it from becoming scattered. At the same time, the elastic contraction of the second spring 507 further absorbs energy and reduces vibration. After the lifting platform rises, the buffer block 502 resets and, together with the limit rod 506, supports the second spring 507 to prevent bending or twisting, thus maintaining stability. The connecting plate 4 connects the buffer mechanism 3 and the elastic mechanism 5 into one unit, thereby maintaining the stability of the lifting platform when it falls and preventing it from tilting.
