Abstract
Description
Technical Field
[0001] This utility model relates to the field of shock-absorbing hydraulic gauge technology, specifically to a multi-directional buffered gauge case for shock-absorbing hydraulic gauges. Background Technology
[0002] A shock-absorbing hydraulic gauge is an instrument used to measure the pressure of a hydraulic system. Its design integrates shock absorption to cope with vibrations and shocks in the system, ensuring the accuracy of the measurement and the durability of the instrument. Its working principle is: by filling the gauge housing with damping fluid (such as silicone oil or glycerin) and installing a buffer mechanism, the viscous resistance of the damping fluid is used to absorb and attenuate mechanical vibrations and media pulsations, thereby stabilizing the pressure measurement value.
[0003] Chinese utility model patent with announcement number CN211205609U discloses a shock-absorbing hydraulic gauge, which includes "a gauge head, a pressure measuring tube, and a shock-absorbing mechanism; the pressure measuring tube is installed on the gauge head and connected to the spring tube inside the gauge head; the shock-absorbing mechanism includes a first flow-blocking block, a second flow-blocking block, and a first reset member, the first flow-blocking block and the second flow-blocking block are both movably installed in the pressure measuring tube, the first flow-blocking block is located on the side of the second flow-blocking block closer to the gauge head, and the first reset member connects the first flow-blocking block and the second flow-blocking block"; This device effectively reduces the impact of instantaneous overpressure on the service life of this invention by adding a shock-absorbing mechanism, and effectively avoids the impact of impurities and air contained in the test object on the accuracy of hydraulic testing. This device effectively reduces the impact of pressure vibration caused by instantaneous overpressure of liquid by incorporating a shock-absorbing mechanism. However, shock-absorbing hydraulic gauges are mostly installed in liquid transport pipelines. When the liquid flows in the pipeline, the pipe body will move and vibrate, which will affect the shock-absorbing hydraulic gauge installed on the surface of the pipeline and cause it to vibrate as well. Over time, the shock-absorbing hydraulic gauge is exposed to vibration, which can lead to loosening and shaking at the connection between the shock-absorbing hydraulic gauge and the pipeline, as well as loosening and damage to the internal components of the shock-absorbing hydraulic gauge, resulting in poor practicality.

[0006] The beneficial effects of this utility model are as follows: This device achieves the effect of buffering and shock absorption of the hydraulic gauge by setting buffer components and shock-absorbing supports. This device is installed by fitting the outer shell onto the top surface of the hydraulic gauge, wrapping the outer wall of the hydraulic gauge with the buffer components on the outer shell and the bottom surface of the outer shell, and fixing it to the outer wall of the pipeline with the support rods on both sides and the clamps at the bottom. During use, the kinetic energy generated by pipeline vibration is absorbed and damped by the shock-absorbing supports on both sides. The vibration generated by the hydraulic gauge is absorbed and damped by the buffer components installed around the hydraulic gauge, thereby effectively reducing the impact of vibration on the hydraulic gauge during use and achieving a multi-directional buffering and damping effect on the hydraulic gauge.
[0007] To achieve an effective hydraulic energy absorption and buffering effect: The design is further configured such that the outer wall of the rubber buffer layer is fixedly connected to the outer wall of the steel plate layer, and the rubber buffer layer and the steel plate layer are stacked alternately on the inner side of the bottom surface of the outer shell.
[0008] By adopting the above technical solution, the rubber buffer layer and steel plate layer are stacked and spaced apart, effectively absorbing and damping the kinetic energy generated by the vibration of the hydraulic gauge, thus achieving a good buffering effect.
[0009] To achieve effective energy absorption and vibration reduction with damping bearings: The connection is further configured such that a lead screw is fixedly connected to the top surface of the connecting cover, the top of the lead screw passes through the top surface of the cover, and a fixing nut is threaded onto the outer side wall of the top of the lead screw.
[0010] By adopting the above technical solution, the connecting cover is installed and connected to the top rod through a screw rod. The connecting rod is pressed down by the top cover, and the energy absorption and shock absorption effect is achieved through the connecting rod and the shock-absorbing spring at its bottom.
[0011] To effectively generate kinetic energy from vibrations for energy absorption and vibration damping: The connection is further configured such that the bottom surface of the connecting cover is fixedly connected to the top surface of the shock-absorbing spring, and the bottom surface of the shock-absorbing spring is movably abutting against the top surface of the base.
[0012] By adopting the above technical solution, when the top cover presses down on the connecting cover, the connecting cover presses down on the shock-absorbing spring, and the shock-absorbing spring effectively absorbs and dampens the kinetic energy generated by the vibration.
[0013] To achieve the desired effect of fixing the connecting rod to the top cover: A further configuration is provided: a rod hole is provided in the middle of the top cover, and a lead screw passes through the rod hole and is installed and connected by a nut.
[0014] By adopting the above technical solution, the connecting cover is connected to the top cover by passing the threaded rod through the rod hole in the middle of the top cover and being fixed by the nut.
[0015] To achieve the effect of transferring the kinetic energy generated by vibration by sliding the connecting cover and the top cover: The top cover is further configured such that sliding plates are fixedly connected to both sides of its bottom surface, the outer walls of the sliding plates on both sides are slidably connected to the inner walls of the rubber layer, and the outer walls of the connecting cover are slidably connected to the inner walls of the sliding plates.
[0016] By adopting the above technical solution, when the top cover is pressed down to absorb shock, the top cover slides within the rubber layer through the sliding plate, while the connecting cover slides within the sliding plate, thereby transferring the kinetic energy generated by vibration to the shock-absorbing spring to achieve the effect of energy absorption and shock absorption.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.
[0021] See Figures 1 to 4 The shock-absorbing hydraulic gauge uses a multi-directional buffer type case, including an outer shell 1, and a buffer element 2 is fixedly connected to the inner side wall of the outer shell 1. Support rods 3 are fixedly connected to the bottom surfaces at both ends of the outer shell 1, and shock absorber supports 4 are fixedly connected to the bottom ends of the support rods 3 on both sides. A clamp 5 is fixedly connected to the bottom surface of each shock absorber support 4. The buffer component 2 includes a rubber buffer layer 21 and a steel plate layer 22; The shock absorber 4 includes a base 41, a rubber layer 42 is fixedly connected to the inner side wall of the base 41, a connecting cover 43 is provided inside the rubber layer 42, and a top cover 44 is movably installed on the top surface of the connecting cover 43.
[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the outer wall of the rubber buffer layer 21 is fixedly connected to the outer wall of the steel plate layer 22, and the rubber buffer layer 21 and the steel plate layer 22 are stacked on the inner side of the bottom surface of the outer shell 1 with intervals between them.
[0023] In this embodiment, as Figure 4 As shown, a lead screw 431 is fixedly connected to the top surface of the connecting cover 43. The top of the lead screw 431 passes through the top surface of the top cover 44, and a fixing nut is threaded onto the outer side wall of the top of the lead screw 431.
[0024] In this embodiment, as Figure 4 As shown, the bottom surface of the connecting cover 43 is fixedly connected to the top surface of the shock-absorbing spring 432, and the bottom surface of the shock-absorbing spring 432 is movably abutting against the top surface of the base 41.
[0025] In this embodiment, as Figure 4 As shown, a rod hole 441 is provided in the middle of the top cover 44, and the lead screw 431 passes through the rod hole 441 and is connected by a nut.
[0026] In this embodiment, as Figure 4 As shown, sliding plates 442 are fixedly connected to both sides of the bottom surface of the top cover 44. The outer walls of the sliding plates 442 on both sides are slidably connected to the inner walls of the rubber layer 42, and the outer wall of the connecting cover 43 is slidably connected to the inner walls of the sliding plates 442.
[0027] This shock-absorbing hydraulic gauge uses a multi-directional buffered case, and its working process is as follows: First, the outer casing 1 is fitted onto the top surface of the hydraulic gauge. The outer wall of the hydraulic gauge is wrapped and installed by the outer casing 1 and the buffer 2 on the bottom surface of the outer casing 1. The gauge is then fixed to the outer wall of the pipe to be tested by the clamps 5 at the bottom of the support rods 3 on both sides. During daily use, the vibration energy generated by the pipeline on this device is transmitted to the damping supports 4 on both sides. The damping supports 4 on both sides are connected to the connecting cover 43 through the installation of the top cover 44 and the connecting cover 43. When the vibration energy is transmitted to the damping support 4, the top cover 44 slides up and down inside the rubber layer 42 through the sliding plate 442 on the bottom surface. At the same time, the connecting cover 43 slides up and down inside the sliding plate 442. The connecting cover 43 compresses the damping spring 432, and the damping spring 432 absorbs the vibration energy and reduces vibration. The connecting cover 43 and the top cover 44 are fixed by the screw 431 passing through the rod hole 441 and the nut. The tightness of the damping spring 432 is adjusted by rotating the nut, thereby achieving the purpose of adjusting the damping effect of the damping spring 432. The vibration energy generated by the pipeline on the hydraulic gauge is transmitted to the buffer 2 through the hydraulic gauge. The rubber buffer layer 21 and the steel plate layer 22 are stacked and spaced to absorb and buffer the kinetic energy transmitted by the hydraulic gauge, thereby achieving the effect of buffering and protecting the hydraulic gauge.
