Description

Technical Field

[0001] This utility model relates to the field of instrument protection equipment technology, specifically a pressure gauge protection device. Background Technology

[0002] Pressure vessels, as important pieces of equipment widely used in the industrial field, require paramount safety. Pressure gauges, as crucial tools for displaying the internal pressure of pressure vessels, play a vital role in ensuring their safe operation.

[0003] During pressure gauge installation, operators typically need to perform preparatory work (such as cleaning equipment interfaces). In the gap between preparation and final tightening, workers often need to temporarily free their hands, and the pressure gauge is often placed directly on the ground. However, the installation site environment is complex, often containing sand, metal shavings, oil, or uneven protrusions. The threaded tube at the bottom of the pressure gauge is in direct contact with the rough ground, making it highly susceptible to scratches from gravel, embedding of foreign objects, deformation from impacts with ground protrusions, or even wear from accidental kicks by personnel. Furthermore, when storing the pressure gauge after use, the threaded tube is easily subjected to collisions, friction, or corrosion during recycling and storage, leading to thread damage, deformation, or contamination. All of these situations can affect the sealing performance of subsequent use and even render the pressure gauge unusable. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 This utility model provides a technical solution: A pressure gauge protection device, as per the instruction manual. Figure 1 As shown, it includes: The pressure gauge body 1 has a threaded tube 2 on one side, which is used to install the pressure gauge body 1 into the pipeline to be measured. The protective assembly includes a protective mechanism and a fitting mechanism. The protective mechanism is used to protect the threaded tube 2, and the fitting mechanism is used to drive the protective mechanism to fit into the threaded tube 2. The switching assembly includes a support frame 3, a connecting mechanism, and an unlocking mechanism. The support frame 3 has a U-shaped structure and is connected to the mounting block 8 via a rotating rod 10. The support frame 3 can rotate around the outside of the pressure gauge body 1, with the rotating rod 10 as the axis. Rotating the support frame 3 is used to switch the protection state (in the non-protection state, the support frame 3 is rotated to the position shown in the attached instruction manual). Figure 1 The position shown can be used. When protecting the threaded pipe 2, rotate the support bracket 3 to the position shown in the instruction manual. Figure 2 (As shown in the image), the support frame 3 is connected to the pressure gauge body 1 via a connecting mechanism. The protection mechanism is located on the support frame 3. Pulling the unlocking mechanism releases the protection mechanism from the connecting mechanism.

[0018] The protective mechanism includes a protective sleeve 4, which is used to protect the threaded pipe 2 and prevent damage to the threaded pipe 2 caused by external forces. The protective sleeve 4 is set on the support frame 3. By sleeved on the outside of the threaded pipe 2, the protective sleeve 4 is used to protect the threaded pipe 2. In actual use, it is necessary to ensure that the depth of the inner side of the protective sleeve 4 is greater than the length of the threaded pipe 2 when the pad 7 is installed, so that the threaded pipe 2 can be completely inserted into the inner side of the protective sleeve 4, thereby making full use of the protective sleeve 4 to protect the threaded pipe 2.

[0019] The fitting mechanism includes a spring 5, a washer 6, and a pad 7. The two ends of the spring 5 are connected to the support frame 3 and the protective cylinder 4, respectively. The spring 5 is used to drive the protective cylinder 4 to fit against the threaded tube 2. The washer 6 is set on the inner wall of the protective cylinder 4. When the protective cylinder 4 fits against the threaded tube 2, the washer 6 wraps around the outside of the threaded tube 2. The washer 6 is a hollow ring structure, and the pad 7 is a disc structure. The washer 6 is used to protect the side wall of the threaded tube 2 and the end of the threaded tube 2. Both the washer 6 and the pad 7 are made of rubber and are relatively soft. Therefore, when protecting the threaded tube 2, they can prevent the threaded tube 2 from being damaged by impact with the protective cylinder 4. In this embodiment, the pad 7 is also provided inside the protective cylinder 4. The pad 7 is set on the inner side wall of the protective cylinder 4. The positional structure diagram of the pad 7 and the washer 6 is shown in the attached figure of the specification.

[0020] The connecting mechanism includes a mounting block 8, a damping bearing 9, and a rotating rod 10. The mounting block 8 is used to install the damping bearing 9. Mounting blocks 8 are fixedly connected to both sides of the pressure gauge body 1. The damping bearing 9 is set on the mounting block 8. The rotating rod 10 is symmetrically arranged on both sides of the support frame 3. The rotating rod 10 is connected to the mounting block 8 through the damping bearing 9. The damping bearing 9 is used to provide a certain resistance when the support frame 3 is adjusted, so as to prevent the rotating rod 10 and the support frame 3 from rotating arbitrarily when installing the pressure gauge body 1, and ensure that the staff will not be affected by the arbitrarily rotating rotating rod 10 and the support frame 3 when installing the pressure gauge body 1.

[0021] A connecting ring 11 is provided on the side where the rotating rod 10 connects to the support frame 3. The connecting ring 11 is used to fix the rotating rod 10 and the support frame 3. The connecting ring 11 is connected to the support frame 3 through a threaded rod 12. The detachable connecting ring 11 allows the operator to unscrew the threaded rod 12 after the pressure gauge body 1 is installed and does not need to be removed for a short period of time, thereby separating the support frame 3, the connecting ring 11, and the rotating rod 10, and removing the support frame 3, the spring 5, and the protective cylinder 4, and reusing the protective device.

[0022] The support frame 3 is provided with an opening to restrict the movement direction of the slide rod 13, so that the slide rod 13 can only move along the direction of the opening. The unlocking mechanism includes the slide rod 13 and the pull plate 14. The slide rod 13 is movably inserted into the opening. One end of the slide rod 13 is fixedly connected to the protective cylinder 4, and the other end of the slide rod 13 is fixedly connected to the pull plate 14. The size of the pull plate 14 is larger than the size of the inner side of the opening, as shown in the attached drawing of the instruction manual. The pull plate 14 is used to limit the sliding range of the slide rod 13 to prevent the problem of "when in the non-protected state (as shown in the attached drawing of the instruction manual), the spring 5 drives the protective cylinder 4 to move, causing the protective cylinder 4 to scratch the outer surface of the pressure gauge body 1". On the other hand, by pulling the pull rod, the slide rod 13 is driven to move, thereby releasing the protection of the threaded tube 2 by the protective cylinder 4. The spring 5 is sleeved on the outside of the slide rod 13.

[0023] Working principle: When the threaded tube 2 needs to be protected, the pull plate 14 is pulled to move the slide rod 13. The movement of the slide rod 13 can move the protective cylinder 4 inside the support frame 3. At this time, the spring 5 is compressed. While pulling the pull plate 14, the support frame 3 can be rotated. When the protective cylinder 4 and the threaded tube 2 are in a coaxial state, the pull plate 14 is slowly released. At this time, the compressed spring 5 will rebound, thereby driving the protective cylinder 4 to protect the threaded tube 2. During protection, the pad 7 and the washer 6 are attached to the outside of the threaded tube 2.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
