Therefore, pressure gauges can be widely used in automobiles, construction machinery, coal mining equipment, chemical equipment and other fields, and are a very important instrument.

[0003] According to Chinese patent CN 218511937 U, a pressure gauge with a protective device is disclosed, which relates to the technical field of pressure gauges. The pressure gauge includes a pressure gauge body, a connector is provided on the pressure gauge body, a protective sleeve is provided on the pressure gauge body, and the protective sleeve cover is provided on the pressure gauge body, and one end of the connector passes through one side of the protective sleeve, and a protective cap is provided on the side of the protective sleeve close to the connector, and the protective cap is connected to the protective sleeve; a protective assembly is provided between the protective sleeve and the pressure gauge body, and the protective assembly protects the pressure gauge body. The pressure gauge body of the present application can be protected when in use or not in use, reducing damage to the pressure gauge body and improving the protective effect of the pressure gauge body.

[0004] Pressure gauges are mostly operated outdoors. Since the mirror of the existing pressure gauge is protected by a cover, dirt and gravel are easily adhered to the surface of the mirror during operation, which may scratch the mirror when the cover is closed, thereby damaging the pressure gauge.

[0005] Therefore, it is necessary to provide a new pressure gauge with a protective structure to solve the above technical problems. Utility Model Content

[0008] A rotating column is rotatably connected to the top of the main body through an axle pin, and the outer wall of the upper end of the rotating column is rotatably connected to a cover plate through a bearing. Gaskets are symmetrically fixed to the bottom of the cover plate, and a toggle column is fixed to the top of the cover plate.

[0009] Preferably, the cleaning mechanism comprises a fixing plate fixed to the bottom of the cover plate, and bristles are fixed to the bottom of the fixing plate at equal intervals.

[0015] Beneficial effects:

[0016] Since the mirror surface of the existing pressure gauge is protected by a cover, the surface of the mirror surface is easily adhered to some dirt and gravel during operation, which may cause the mirror surface to be scratched when the cover is closed, thereby causing damage to the pressure gauge. The cooperation of the cleaning mechanism and the protection mechanism can automatically clean the mirror surface of the pressure gauge when the cover is closed or opened, thereby avoiding damage to the mirror surface when the cover is closed;

[0017] In addition, the quick-install mechanism can be used to quickly remove and install the fixing plate by pressing the locking block, and the operation is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] See also Figures 1 to 4 The embodiment of the present invention provides a pressure gauge with a protective structure, comprising a main body 1, wherein the bristles 202 are made of a flexible material, a protective mechanism 2 for protecting the pressure gauge mirror is installed on the top of the main body 1, a cleaning mechanism 3 for cleaning the pressure gauge mirror is installed on the bottom of the protective mechanism 2, and a quick-installation mechanism 4 for quickly installing the cleaning mechanism 3 is installed inside the cleaning mechanism 3, and the protective mechanism 2 includes:

[0026] A rotating column 101 is rotatably connected to the top of the main body 1 through an axle pin, and the outer wall of the upper end of the rotating column 101 is rotatably connected to the cover plate 102 through a bearing. A gasket 103 is symmetrically fixed to the bottom of the cover plate 102, and a toggle column 104 is fixed to the top of the cover plate 102. The outer wall of the toggle column 104 is fixed with an anti-slip ring 5.

[0027] Preferably, the cleaning mechanism 3 includes a fixing plate 201 fixed to the bottom of the cover plate 102 , and bristles 202 are fixed to the bottom of the fixing plate 201 at equal intervals.

[0028] Preferably, the quick-loading mechanism 4 includes a slot 301 on the top of the fixed plate 201, an inner wall of the slot 301 is symmetrically provided with an oblique slot 302, a spring 303 is fixed on the inner side of the slot 301, a sliding hole 304 is provided on the top of the cover plate 102, a locking block 305 is slidably connected to the inner side of the sliding hole 304, an anti-slip groove 6 is provided on the top of the locking block 305, and an outer wall of the locking block 305 is symmetrically connected to a clamping strip 306 through an axle pin for rotation, and the clamping strip 306 is clamped with the oblique slot 302.

[0029] Compared with the comparative documents, the present application can automatically clean the mirror surface of the pressure gauge when the cover 102 is closed or opened through the cooperation of the cleaning mechanism 3 and the protective mechanism 2, thereby avoiding damage to the mirror surface when the cover 102 is opened. In addition, the quick-installation mechanism 4 can quickly disassemble and install the fixing plate 201 by pressing the locking block 305, and the operation is relatively simple.

[0030] The working principle of a pressure gauge with a protective structure provided by the utility model is as follows:

[0031] When the cover 102 needs to be opened, first turn the toggle column 104 counterclockwise to drive the cover 102 to rotate on the rotating column 101, and at the same time drive the fixed plate 201 to rotate, and then the fixed plate 201 drives the bristles 202 to clean the mirror until the cover 102 is in a fully opened state. Then, when the cover 102 needs to be closed, just turn the toggle column 104 again to rotate the cover 102 clockwise and drive the bristles 202 on the fixed plate 201 to clean the pressure gauge again. The mirror surface is cleaned until the cover 102 is completely closed. In addition, when the bristles 202 need to be replaced, it is only necessary to press the locking block 305 downward first, and then the locking block 305 squeezes the spring 303. Since the contact surface of the locking block 305 is not coaxial with the spring 303, the card strip 306 is driven to slide out from the right side of the inclined groove 302. Then release the pressing force, and then the reaction force of the spring 303 drives the locking block 305 to pop up, thereby taking out the fixing plate 201, and completing the disassembly work.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
