Description
本創作涉及用於測量流體壓力的裝置，特別是涉及一種壓力表及具有該壓力表的充***。The present invention relates to a device for measuring fluid pressure, and more particularly to a pressure gauge and an inflatable gun having the same.
目前，一般壓力表標準(GB/T1266-2001)及抗震壓力表標準(GB/T6803-2006)對自由落下高度的要求是250mm，但壓力表實際使用的高度大大超過了250mm。比如，如汽車用輪胎充***、量測汽車真空度的真空表、測量汽車氣缸壓力的氣缸壓力表等，工作者拿在手上使用工具經常失手掉落地下的高度遠超過國家標準250mm。At present, the general pressure gauge standard (GB/T1266-2001) and the seismic pressure gauge standard (GB/T6803-2006) require 250mm for the free fall height, but the actual height of the pressure gauge is much more than 250mm. For example, such as automobile tire inflation guns, vacuum gauges for measuring automobile vacuum, cylinder pressure gauges for measuring automobile cylinder pressure, etc., workers often use their tools to lose their hands and fall to a height far exceeding the national standard of 250mm.
為了提高壓力表的抗震性能，通常採用膜片壓力表。現有膜片壓力表主要由外殼、壓力表本體、表板、指針和透光板組成，其中，外殼具有封閉的底端和開口的頂端，壓力表本體裝於外殼內，壓力表本體的固定座與底端之間透過對稱的兩顆螺釘固定。這種膜片壓力表的自由落下高度可達500mm，但是，由於底殼與固定座之間僅用兩顆對稱螺釘固定，當工具落下時，落下點在螺釘的90度方向重力集中在外殼邊緣，固定螺釘成為支點，外殼在重力加速度瞬間變形，壓到壓力表表板變形，嚴重變形後卡住壓力表指針造成壓力表不準或損壞。In order to improve the seismic performance of the pressure gauge, a diaphragm pressure gauge is usually used. The existing diaphragm pressure gauge is mainly composed of a casing, a pressure gauge body, a watch plate, a pointer and a light-transmitting plate, wherein the outer casing has a closed bottom end and an open top end, the pressure gauge body is installed in the outer casing, and the pressure gauge body is fixed. Secured by symmetrical two screws between the bottom and the bottom. The diaphragm can be freely dropped to a height of 500 mm. However, since only two symmetrical screws are used between the bottom case and the mount, when the tool is dropped, the drop point is concentrated on the edge of the case at a 90 degree angle of the screw. The fixing screw becomes the fulcrum, and the outer casing is deformed instantaneously under the acceleration of gravity, and is pressed to the surface of the pressure gauge to be deformed. When the deformation is severely deformed, the pointer of the pressure gauge is caught, causing the pressure gauge to be inaccurate or damaged.
針對上述現有技術現狀，本創作所要解決的技術問題在於，提供一種抗震性能良好的壓力表及具有該壓力表的充***，以避免壓力表跌落損壞，延長使用壽命。In view of the above state of the art, the technical problem to be solved by the present invention is to provide a pressure gauge with good seismic performance and an inflation gun having the pressure gauge to prevent the pressure gauge from falling and damage and prolonging the service life.
