Abstract
Description
Technical Field
[0001] This application relates to the field of small machinery, and particularly to a small telescopic cylinder with a conical connection type. Background Art
[0002] A telescopic cylinder is generally a cylindrical metal part that guides a piston to perform linear reciprocating motion in the cylinder. It usually consists of a cylinder barrel, end covers, a piston, a piston rod, and seals, etc. Air expands in the engine cylinder to convert heat energy into mechanical energy, and gas is compressed by the piston in the compressor cylinder to increase pressure.
[0003] In the prior art, the cylinder pushes the piston through gas compression. However, when controlling the movement of the piston by gas, due to the instability of the gas, it will cause excessive or insufficient movement at the output end. When the gas controls the piston to move too much, it will generate excessive impact force on the connection part of the output end. When the gas controls the piston to move too little, it will reduce the stability of the connection. Over time, it will lead to a decrease in the connection reliability, and at the same time, it will also cause a change in the relative position of the connection part of the output end, thereby affecting the sealing effect of the seal.

[0031] The following further elaborates on the present application in conjunction with Figure 1 —4.
[0032] The embodiment of the present application discloses a conical connection type small telescopic cylinder.
[0033] The observation views (front, back, left, right) of this device are based on Figure 1 as the reference benchmark.
[0034] Referring to Figures 1-4 , the conical connection type small telescopic cylinder includes an outer shell 1 and a telescopic mechanism 2. The circular through holes 201 are symmetrically opened through both sides of the outer shell 1. The first thread groove 202 is opened in the middle of one side of the outer shell 1. The thread hole 203 is opened through the bottom of the outer shell 1. One end of the first hollow column 204 is threadedly connected to the inside of the thread hole 203. The outside of the first thread column 205 is threadedly connected to one side of the first thread groove 202. Both ends of the connecting column 206 are respectively fixedly connected to one side of the first thread column 205 and one side of the fixed piece 207. The middle of the fixed piece 207 is fixedly connected to one end of the second hollow column 208. The outer wall of the frustum block 209 is slidably connected to the inside of the first thread groove 202. The middle of the conical head 210 is slidably connected to the inside of the second hollow column 208.
[0035] The middle part of the sliding column 211 is slidably connected to the outside of the hollow column 208, the outside of the sliding column 211 is slidably connected to the inside of the threaded column 1 205, the circular groove 212 is opened on one side of the sliding column 211, the inside of the fixing ring 213 is fixedly connected to the outer wall of the sliding column 211 inside the circular groove 212 by screws, the semi-ring piece 1 214 and the semi-ring piece 2 215 are clamped between the fixing ring 213 and the threaded column 1 205, and the semi-ring piece 1 214 and the semi-ring piece 2 215 are plugged together, and at the same time It is sleeved on the outside of the sliding column 211, and the annular groove 216 is opened on the other side of the sliding column 211. The two ends of the spring 217 are respectively fixedly connected to the surface of the annular groove 216 and the inner wall of the arc block 218. The outer wall of the arc block 218 abuts against the inside of the threaded column 1 205. The threaded groove 219 is opened on one side surface of the truncated cone block 209. One end of the threaded column 220 is fixedly connected to one end of the conical head 210, and the other end of the threaded column 220 is threadedly connected to the inside of the threaded groove 219.
[0036] The hollow column 204 is connected to an external air pump, which is not a major technical feature and will not be described in detail here.
[0037] When installing the shell 1, the operator inserts the shell 1 into the corresponding device through the round hole 201, and then starts the air pump. At this time, the compressed gas enters the threaded hole 203 through the inside of the hollow column 204. At the same time, since the truncated cone block 209 isolates the two sides of the inside of the thread groove 202, the threaded column 205 seals one side of the thread groove 202, and the compressed gas will accumulate on one side of the truncated cone block 209.
[0038] As the pressure difference on both sides of the truncated cone block 209 gradually increases, the truncated cone block 209 begins to slide inside the thread groove 1 202 . Through the sliding of the truncated cone block 209 , the conical head 210 begins to slide inside the hollow column 208 . At this time, the connection can be made by plugging the conical head 210 .
[0039] When it is necessary to adjust the telescopic distance of the conical head 210, the operator manually removes the semi-ring piece 1 214 and the semi-ring piece 215 that are stuck on the outside of the sliding column 211. After completion, the operator manually slides the sliding column 211, and the sliding column 211 begins to slide between the hollow column 208 and the threaded column 205. When one side of the fixing ring 213 fits with one side of the threaded column 205, the arc block 218 and the spring 217 inside the connecting column 206 are no longer interfered by the threaded column 205. The spring 217 begins to stretch, pushing the arc block 218 outward from the inside of the annular groove 216, shortening the distance between the truncated cone block 209 and the threaded column 205, and the conical head 210 can be moved to the operator's ideal distance.
[0040] When replacing the arc-shaped block 218 with different widths or when the interior of the housing 1 needs to be reset, since this cylinder has a one-way output, manual reset is required. The operator removes the screw inside the circular groove 212 with a screwdriver, and then rotates the first threaded post 205. When the first threaded post 205 is removed from the inside of the first threaded groove 202, the sliding post 211 can be removed and replaced. Subsequently, the replaced sliding post 211 is inserted between the first threaded post 205 and the second hollow post 208. During the insertion process, the operator manually presses the arc-shaped block 218 outside the circular ring groove 216 to contract the spring 217. When the entire sliding post 211 is inserted, the fixing ring 213 is fixed outside the circular groove 212 and the sliding post 211 with screws. Subsequently, the first half-ring piece 214 and the second half-ring piece 215 are clamped between the fixing ring 213 and the first threaded post 205, and then the first threaded post 205 is rotated back into the inside of the first threaded groove 202 to complete the replacement.
[0041] When the conical head 210 is severely worn, the operator can directly rotate the conical head 210 to remove one side of the conical head 210 from one side of the frustum-shaped block 209. When the frustum-shaped block 209 is severely worn, after removing the first threaded post 205, the frustum-shaped block 209 and the conical head 210 can be manually rotated and disassembled, and then a new frustum-shaped block 209 is replaced to complete the replacement.
[0042] The implementation principle of the conical connection type small telescopic cylinder in the embodiment of this application is as follows: The operator fixes the housing 1 through the circular through-hole 201. Subsequently, according to how much the conical head 210 needs to extend, the operator manually removes the screw inside the circular groove 212 with a screwdriver, and then rotates the first threaded post 205 and removes it from the inside of the first threaded groove 202, and then the sliding post 211 can be replaced. Subsequently, the replaced sliding post 211 is inserted between the first threaded post 205 and the second hollow post 208. When inserting, it is not necessary to insert the arc-shaped block 218 inside the first threaded post 205. Subsequently, the fixing ring 213 and the circular groove 212 are fixed, and the first threaded post 205 is rotated inside the first threaded groove 202 to complete the adjustment.
[0043] When only the maximum extension distance of the conical head 210 is required, after removing the first threaded post 205, manually press the arc-shaped block 218 and slide the sliding post 211 to slide the arc-shaped block 218 inside the first threaded post 205. Subsequently, the first half-ring piece 214 and the second half-ring piece 215 are used to fix the sliding post 211. When the frustum-shaped block 209 or the conical head 210 needs to be replaced, only after removing the first threaded post 205, manually rotate the frustum-shaped block 209 and the conical head 210 to replace one of them separately.
[0044] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
