Description

Technical Field

[0001] The utility model relates to the technical field of buffers, and more specifically, to a telescopic and adjustable buffer. Background Art

[0002] The buffer relies on elastic bodies, hydraulic pressure, air pressure, damping, etc. to buffer and decelerate the objects acting on it to a stop, playing a certain degree of protection role. It is often used in large equipment to prevent hardware collisions from causing damage to the mechanism.

[0003] The buffer often needs to be installed in a preset position, and uses its own compression and resetting to achieve changes in the matching relationship with the cavity. When the buffer is not under pressure, the buffer's impact head and piston rod are at the highest position. In a narrow space or in a prefabricated device, the buffer cannot be installed in the specified position due to its too high size, and thus the buffer cannot be installed and removed in a small space or in a device that cannot be removed.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a telescopic and adjustable buffer in order to solve the above-mentioned problems.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a telescopic adjustable buffer, comprising an outer cylinder body, one end of the outer cylinder body is slidably connected to the inner cylinder body, a chamber is formed between the outer cylinder body and the inner cylinder body, a sealing plate is slidably connected in the chamber, one end of the sealing plate is provided with a plug extending to the outside of the outer cylinder body, the other end of the outer cylinder body is threadedly connected to a rotating screw cover, the rotating screw cover is provided with a rotating handle fixedly connected to the rotating screw cover, and the bottom of the rotating top cover abuts against the sealing plate.

[0007] The utility model is further configured as follows: a necking is provided on the outer cylinder body, an internal thread is provided on the necking, and an external thread is provided on the outer wall of the rotary screw cover.

[0008] The utility model is further configured as follows: the height of the rotating screw cap is greater than the thickness of the necking opening.

[0009] The utility model is further configured as follows: a through hole is provided on the rotating screw cover, the plug extends to the outer cylinder body through the through hole, and a protrusion is provided on the top of the plug

[0010] The utility model is further configured as follows: a sealing ring is arranged between the blocking plate and the outer cylinder body.

[0011] In summary, the utility model has the following beneficial effects:

[0012] During installation, the buffer can be installed to the specified position first, and then the rotating handle can be turned to increase the overall length of the buffer so that the protrusion and the inner cylinder body are in contact with the equipment at the same time, thereby achieving stable installation of the buffer. When disassembly is required, the rotating handle can be turned in the opposite direction to shorten the total length of the buffer, thereby loosening the buffer and facilitating its removal. During this process, no tools or other auxiliary means are required, and it can be achieved by simply turning the rotating handle, thereby simplifying the disassembly and assembly process of the buffer.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0018] Telescopic adjustable buffer, such as Figure 1As shown, it includes an outer cylinder body 1, one end of which is slidably connected to an inner cylinder body 2, a chamber is formed between the outer cylinder body 1 and the inner cylinder body 2, the chamber can be filled with gas or liquid or other elastic fillers, and the air pressure, hydraulic pressure or elastic deformation of the filler is used to absorb part of the force, thereby realizing the buffering effect of the buffer, thereby protecting the equipment as a whole, a sealing plate 6 is slidably connected in the chamber, one end of the sealing plate 6 is provided with a plug 7 extending to the outside of the outer cylinder body 1, the sealing plate 6 is used to seal the chamber, so that the gas or liquid in the chamber can effectively use its air pressure or hydraulic pressure to achieve a buffering effect, and the plug 7 is used to abut against the equipment, when the equipment is impacted, the sealing plate 6 slides, so that the volume of the chamber changes, thereby causing the air pressure, hydraulic pressure or elastic filler volume in the chamber to change, thereby achieving the effect of absorbing the impact force, the other end of the outer cylinder body 1 is threadedly connected to a rotating screw cap 3, rotating The screw cap 3 is provided with a rotating handle 4 fixedly connected with the rotating screw cap 3, and the bottom of the rotating top cover abuts against the sealing plate 6. The fixedly connected rotating handle 4 can make the rotating screw cap 3 rotate synchronously with it, and the threaded connection method makes the rotating screw cap 3 also accompanied by up and down displacement when rotating. Therefore, after it abuts against the sealing plate 6, the tightness of its thread can also be used to affect the highest position of the sealing plate 6 in the outer cylinder body 1, thereby limiting the sealing plate 6. At the same time, since the rotating screw cap 3 makes the position of the sealing plate 6 adjustable, it can be used to adjust whether the plug 7 abuts against the equipment. When the buffer is installed, the threaded connection of the rotating screw cap 3 can be loosened so that the plug 7 rises to abut against the equipment, thereby making the buffer firmly installed in place. When the buffer is disassembled, the threaded connection of the rotating screw cap 3 can be tightened, thereby releasing the abutment state of the plug 7 with the equipment, thereby loosening the buffer, thereby facilitating the removal of the buffer.

[0019] like Figure 1 and Figure 2 As shown, a reduction opening 5 is provided on the outer cylinder body 1, an internal thread 51 is provided on the reduction opening 5, and an external thread 31 is provided on the outer wall of the rotary screw cover 3. The reduction opening 5 can also limit the sealing plate 6, and is also the specific position on the outer cylinder body 1 that is threadedly connected to the rotary screw cover 3. The height of the rotary screw cover 3 is greater than the thickness of the reduction opening 5. This arrangement ensures that the rotary screw cover 3 has enough space to adjust the position of the sealing plate 6.

[0020] like Figure 1 and Figure 2 As shown, a through hole is provided on the rotating screw cover 3, and the plug 7 extends to the outside of the outer cylinder body 1 through the through hole. A protrusion 8 is provided on the top of the plug 7. The protrusion 8 is used to increase the area of ​​the abutment part between the plug 7 and the equipment, reduce the pressure generated by the buffer on the equipment, and thus can protect the equipment and the buffer at the same time, and also make the installation of the buffer more stable, ensuring the normal use of the buffer.

[0021] like Figure 3 As shown, the cross-section of the rotating cover 3 can be circular or hexagonal. When the buffer is used in a device with a smaller impact force, the rotating handle 4 can be used to drive the rotating cover 3 to achieve complete functions. When the buffer is used in a device with a larger impact force, since the buffer needs to be installed more firmly, the threaded connection strength between the rotating handle 4 and the neck 5 is higher. Even by rotating the handle 4, a larger force is required to drive it to rotate. At this time, the hexagonal cross-section allows the rotating cover 3 to be further labor-saving with the help of a wrench.

[0022] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
