[0015] Compared with the existing relay calibration and detection device technology, the present invention provides a relay calibration and detection device capable of buffering vibration, which has the following beneficial effects:

[0017] 2. The present invention arranges an inflating device below the detector body and an electric control assembly at the upper end of the inflating device. When the detector body vibrates downward, the conductive contact on the lower end surface of the detector body can contact the conductive sheet on the electric control assembly, thereby triggering the inflating device to start working. The gas generated by the air pump is transported to the spiral tube and replenished into the airbag through the three-way pipe in the fixed block. The expansion effect of the airbag is used to assist the detector body to remain horizontal.

[0018] 3. The present invention installs an electromagnetic gas valve on the exhaust pipe. When the conductive contact on the lower end surface of the detector body is disconnected from the electronic control component, the air pump stops supplying gas and controls the electromagnetic gas valve on the exhaust pipe to open, so that the gas in the airbag is discharged through the exhaust pipe. Through repeated gas replenishment and release processes, the position of the detector body is kept stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the detector body 2 is vibrated, it starts to swing up and down, and then presses the force relief component 12 below. The vibration pressure is buffered by the force relief component 12 to reduce the vibration damage to the internal components of the detector body 2. A conductive contact 9 is also provided on the left bottom wall of the detector body 2. An inflation device for replenishing gas to keep the detector body 2 horizontal is installed on the left inner wall of the outer shell 1. The inflation device is provided with an electric control component that can be electrically connected to the conductive contact 9 when the detector body 2 rotates downward. When the detector body 2 is vibrated and swings downward, the conductive contact 9 on the lower end face of the detector body 2 can just touch the electric control component to achieve electrical connection of the control circuit, so that the inflation device starts to work, which is beneficial to the gas expansion effect generated by the inflation device and assists the detector body 2 to keep the level.

[0027] The unloading assembly 12 includes a spiral tube 121 and a top plate 124. The spiral tube 121 is rotatably connected to the top plate 124 through a bearing. The bearing includes an inner shaft ring 126, a roller 127 and an outer shaft ring 128. The roller 127 is annularly distributed on the outer side of the inner shaft ring 126 and sleeved in the outer shaft ring 128. The outer shaft ring 128 is fixed to the bottom wall of the top plate 124 so that the inner shaft ring 126 can rotate relative to the outer shaft ring 128. Two toggle rods 129 are fixedly connected to both sides of the lower end of the inner shaft ring 126. A spiral groove 122 is opened on the outer wall of the spiral tube 121. The lower ends of the two toggle rods 129 are retracted inwardly and inserted into the spiral groove 122. When the top plate 124 is subjected to downward pressing force, due to the two The toggle rod 129 spirally rotates along the spiral groove 122, converting the impact potential energy into the rotational kinetic energy of the inner shaft ring 126 and the friction loss between the toggle rod 129 and the spiral groove 122, thereby gradually buffering and releasing the impact force during vibration. The upper end of the spiral tube 121 is fixedly connected with an airbag 125, and the airbag 125 is supplemented with gas through an inflation device to expand the airbag 125. A spring 123 is arranged on the outside of the airbag 125, and the two ends of the spring 123 are respectively against the spiral tube 121 and the top plate 124. When the internal gas of the airbag 125 is discharged, the top plate 124 is restored to its original height under the action of the spring 123, and the lower end of the spiral tube 121 is fixedly connected with a fixing block 15.

[0028] The inflation device includes an air pump 7, and a three-way pipe is arranged in the fixed block 15. The left end of the three-way pipe is connected to the output end of the air pump 7, and the right end of the three-way pipe is connected to the exhaust pipe 14. The exhaust pipe 14 is equipped with an electromagnetic valve 13. The upper end of the three-way pipe is connected to the spiral tube 121. The gas generated by the air pump 7 is transported to the spiral tube 121 through the three-way pipe and replenished into the airbag 125. When the conductive contact 9 on the lower end face of the detector body 2 is disconnected from the electronic control component, the air pump 7 stops supplying gas, and at the same time controls the electromagnetic valve 13 on the exhaust pipe 14 to open, and the gas in the airbag 125 is discharged through the exhaust pipe 14, thereby keeping the position of the detector body 2 stable.

[0029] The electronic control component includes a controller 8, which is fixedly mounted on the upper end surface of the air pump 7. A conductive sheet 10 is provided on the controller 8, and the conductive sheet 10 is on the rotation path of the conductive contact 9. When the detector body 2 vibrates downward, the conductive contact 9 on the lower end surface of the detector body 2 can contact the conductive sheet 10 on the controller 8, thereby triggering the inflation device to start working. At the same time, when the conductive contact 9 is disconnected from the conductive sheet 10, the electromagnetic valve 13 on the exhaust pipe 14 can be triggered to open.

[0030] In order to achieve air path connectivity, the inner hollow of the spiral tube 121 forms an airway 121 - 2 connected to the annular groove 121 - 1, so that the gas delivered by the air pump 7 can be replenished into the airbag 125 through the spiral tube 121, and the top plate 124 is kept level by the collision of the airbag 125.

[0031] In order to improve the stability of the airbag 125, an annular groove 121-1 is opened on the upper end surface of the spiral tube 121, and the lower end of the airbag 125 is fixed in the annular groove 121-1 to prevent the airbag 125 from being separated from the spiral tube 121 due to excessive gas pressure. At the same time, the airbag 125 and the spiral tube 121 are connected by a seal to maintain air tightness.

[0032] In order to maintain the stability of the detector body 2, one end of a spring 3 is fixedly connected to the top right side of the detector body 2, and the other end of the spring 3 is fixedly connected to the inner wall of the outer shell 1 to increase elastic contact and prevent the detector body 2 from colliding with the inner wall of the outer shell 1 when rebounding upward, thereby protecting the detector body 2.

[0033] The working principle and use process of the present invention are as follows: when the detector body 2 vibrates, the detector body 2 can be directional rotated at the right hinge point, and then the pressing rod 11 on the lower end surface of the detector body 2 presses the unloading component 12 below accordingly. When the top plate 124 is subjected to downward pressing force, the two toggle rods 129 spirally rotate along the spiral groove 122, converting the impact potential energy into the rotational kinetic energy of the inner shaft ring 126 and the friction loss between the toggle rod 129 and the spiral groove 122, thereby gradually buffering and releasing the impact force during vibration. At the same time, when the detector body 2 vibrates downward, the conductive contact on the lower end surface of the detector body 2 Point 9 can contact the conductive sheet 10 on the controller 8, thereby triggering the inflation device to start working, and the gas generated by the air pump 7 is transported to the spiral tube 121 through the three-way pipe in the fixed block 15 and replenished into the airbag 125. The expansion effect of the airbag 125 is utilized to assist the detector body 2 to maintain the horizontality. After the detector body 2 maintains the horizontality, the conductive contact 9 on the lower end face of the detector body 2 is disconnected from the conductive sheet 10, thereby triggering the electromagnetic valve 13 on the exhaust pipe 14 to open. The vibration pressure is gradually buffered by the mutual cooperation of the unloading component 12 and the inflation device, thereby reducing the vibration damage to the internal components of the detector body 2.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
