Description

Technical Field

[0001] The utility model relates to the field of instrument equipment, in particular to a dial disassembly device. Background Art

[0002] A large number of pressure gauges are required in shipbuilding. During the construction process, due to the long construction period and many cross-construction operations, although various protective measures are taken during the construction process, it is inevitable that collisions will cause damage to the pressure gauge glass; once the pressure gauge glass is damaged, it faces the problem of replacement. The price of conventional pressure gauges ranges from tens to hundreds of yuan, and the replacement cost is not high. The price of special pressure gauges is several thousand to tens of thousands of yuan, which is very expensive, and most of them are imported products. It takes a long time to repurchase them. If the construction project cannot be advanced due to the damage of the pressure gauge, at the very least, a large amount of labor will be spent on recovery. At worst, it will affect the delivery of the ship. The economic loss caused by any result will far exceed the value of the pressure gauge itself.

[0003] In the existing technology, there is no good tool for quickly and non-destructively disassembling the dial of the pressure gauge whose glass is broken after installation. In the existing technology, the dial is mostly disassembled by directly applying pressure on the side of the dial, which is easy to slip and cannot be quickly disassembled. Excessive pressure can easily damage the surface of the dial, causing the dial to deform and become unusable. Utility Model Content

[0005] The accommodating cavity is also provided with an elastic hoop disc pad, and the hoop disc pad is arranged between the pressure plate and the dial;

The hoop plate pad can disperse the force applied by the pressure plate over a larger area to avoid damage to the dial caused by excessive and concentrated pressure, which causes deformation of the dial. This also makes it possible to apply a greater positive pressure to increase the friction force in the process of removing the instrument panel without worrying about damage to the dial caused by excessive concentration of positive pressure, thereby facilitating the removal of the instrument panel; the anti-skid pattern on the pressure plate can squeeze out uneven patterns on the hoop plate pad, increase the surface friction coefficient of the hoop plate pad, thereby further increasing the friction force on the instrument panel, and facilitating the removal of the instrument panel; the setting of the force adding rod can better provide the card holder body with rotational force to remove the instrument panel. While saving effort, the present invention can achieve faster, safer and more lossless removal of the instrument panel, thereby replacing the broken glass. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figures 1 to 5 As shown, a preferred embodiment of the utility model provides a dial disassembly device, which includes a socket body 1 and a force rod 2; the socket body 1 includes a receiving cavity 11 for receiving the instrument, and the socket body 1 is also threadedly connected with a plurality of locking members 3, the front end of the locking member 3 extends into the receiving cavity 11 and is provided with a pressure plate 31 for applying pressure to the dial, and one side of the pressure plate 31 is provided with an anti-slip pattern 311 for abutting the dial; the receiving cavity 11 is also provided with an elastic hoop disc pad 12, and the hoop disc pad 12 is arranged between the pressure plate 31 and the dial; the middle part of the force rod 2 is fixedly arranged on the top surface of the socket body 1; the force rod 2 is used to drive the socket body 1 to rotate.

[0027] Specifically, when the installed instrument panel is hit and the glass is damaged, and the glass needs to be replaced, the card holder body 1 can be quickly put on the instrument panel, so that the dial contacts the hoop disc pad 12, and the hoop disc pad 12 will protect the dial and prevent the dial from being damaged again; then adjust and screw in the locking piece 3, so that the pressure plate 31 presses the hoop disc pad 12, so that the hoop disc pad 12 is deformed and the pressure of the locking piece 3 is dispersed on the side wall of the dial to avoid damage to the dial caused by excessive concentration of pressure. At the same time, because the pressure is dispersed over a larger contact area, the locking piece 3 can also apply a larger pressure without damaging the dial, which makes the dial and the hoop disc pad 12 more tightly connected. The friction between the disc guard pad 12 is increased, and the dial can be better driven to rotate during the rotation of the socket body 1, so that the dial can be removed; further, the anti-skid pattern 311 on the pressure plate 31 will squeeze the disc guard pad 12, so that the anti-skid pattern 311 also appears on the side facing the dial, thereby increasing the surface friction coefficient of the disc guard pad 12, and further enhancing the friction between the disc guard pad 12 and the dial, which is convenient for the subsequent removal of the dial; in addition, the force rod 2 is fixed in the middle to the top surface of the socket body 1. In the process of removing the dial, the user can place both hands on the two ends of the force rod 2 and apply force at the same time, so that the dial can be removed more easily and quickly.

[0028] In some embodiments, the locking member 3 includes a jacking bolt 32, and the side wall of the socket body 1 is provided with a threaded through hole 13 corresponding to the jacking bolt 32, and the end of the jacking bolt 32 is abutted against the pressure plate 31; a limiting rod 312 is provided on the side of the pressure plate 31 away from the anti-slip pattern 311, and the socket body 1 is provided with a limiting through hole 14 corresponding to the limiting rod 312.

[0029] Specifically, a limiting rod 312 is fixedly provided on one side of the pressure plate 31 away from the center of the accommodating chamber 11, and the limiting rod 312 is arranged in the limiting through hole 14. The pressure plate 31 is slidably connected to the base body 1 through the limiting rod 312, and will not rotate with the jacking screw; a groove is provided on one side of the pressure plate 31 close to the jacking bolt 32, and the front end of the jacking bolt 32 is arranged in the groove. When the jacking bolt 32 rotates and jacks, the front end of the jacking bolt 32 rotates in the groove and pushes the pressure plate 31 toward the center of the accommodating chamber 11 to squeeze the hoop disc pad 12.

[0030] In some embodiments, the pressure plate 31 is an arc-shaped structure. Specifically, compared with a straight plate, the arc-shaped pressure plate 31 can better fit the outer structure of the dial, better apply positive pressure to the dial to increase friction, and the contact area with the dial will be larger; in addition, in some embodiments, the pressure plate 31 is made of a tough plastic material, which has lower cost and better strength. When facing instruments of different diameters, it can be deformed to fully fit the dial, provide positive pressure to the dial, and has better applicability, which can meet the use requirements of dials of more instruments with different diameters.

[0031] In some embodiments, the anti-skid pattern 311 includes multiple groups of protrusions evenly distributed along the arc of the pressure plate 31. Specifically, the protrusions on the pressure plate 31 can squeeze the hoop plate pad 12 to form protrusions, thereby increasing the surface friction roughness of the hoop plate pad 12, that is, the friction coefficient, thereby increasing the friction force on the dial; in addition, the multiple groups of protrusions in the anti-skid pattern 311 can be arranged in different patterns or shapes to further enhance the friction force on the dial.

[0032] In some embodiments, anti-skid kits 21 are provided at both ends of the force-adding rod 2. The anti-skid kits 21 prevent slippage due to hand sweat and other reasons when applying force to the force-adding rod 2, and can better drive the card seat body 1 to rotate, thereby driving the dial to rotate.

[0033] In some embodiments, four locking members 3 are arranged along the axis of the card seat body 1; the angle between the force rod 2 and any locking member 3 is 45 degrees. The angle between the force rod 2 and the locking member 3 is to facilitate the adjustment of the locking member 3 and the rotation of the jacking bolt 32. In other embodiments, three locking members 3 can also be evenly distributed along the axis of the card seat body 1.

[0034] In some embodiments, a glass pad 15 is further provided in the accommodating cavity 11, and the glass pad 15 is used to prevent the instrument glass from being further damaged. Specifically, when the instrument glass is severely damaged, the glass pad 15 can disperse and reduce the pressure on the edge of the broken glass, preventing the glass from being further damaged and causing debris to splash. When the instrument glass is slightly damaged, the glass pad 15 can buffer the glass and prevent the card seat body 1 from pressing on the glass and causing further damage. In addition, when installing new glass, the glass pad 15 can provide protection for the new glass to prevent the new glass from being damaged due to excessive pressure.

[0035] In some embodiments, the card base body 1 is a cylindrical structure, and the force rod 2 is welded and fixed to the card base body 1. The card base body 1 and the force rod 2 are both made of metal, which has higher strength, lower cost and simpler structure.

[0036] In some embodiments, the hoop pad 12 is made of a sponge material with a rough surface. The sponge material can provide a larger surface friction coefficient and is softer in nature, which can protect the dial while increasing the friction force on the dial.

[0037] In summary, the embodiment of the utility model provides a dial disassembly device, which can increase the friction force on the dial by setting structures such as a hoop plate pad 12, a pressure plate 31 and an anti-slip pattern 311, thereby facilitating the removal of the dial and protecting the dial to avoid damage to the dial due to excessive concentrated pressure.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
