Description

Technical Field

[0001] This utility model relates to the field of sealing cap technology, and in particular to a combined pressure warning sealing cap. Background Technology

[0002] A pressure warning cap is a safety device used to monitor and provide early warning of pressure changes inside a sealed container. Pressure warning caps are commonly used to monitor and maintain the operating status of air conditioning systems, particularly for real-time pressure monitoring within the refrigerant circulation system.

[0003] For example, a pressure warning cap and air conditioner disclosed in CN204879261U include a cap base; a cavity extending through the cap base; and an elastic expansion ring disposed in the cavity, with its edge inlaid and injection-molded into the cap base. This invention's pressure warning cap uses the edge of the elastic expansion ring in the cap base, creating a permanent connection between the ring and the base. This prevents sealing failure and improves the sealing effect. However, because this pressure warning cap cannot provide an alert when pressure changes, it requires personnel to observe the position of the protruding part to determine the relationship between the internal and external pressures, which can easily lead to misjudgment or omission, and is also labor-intensive.

[0004] Therefore, a combined pressure warning cap has now been developed that can automatically issue alerts when pressure changes occur without human intervention. Utility Model Content

[0005] To overcome the shortcomings of existing pressure warning caps, which cannot issue alerts when pressure changes occur and require staff to observe the position of the protrusion to determine the relationship between internal and external pressures, leading to misjudgments or omissions and wasting manpower, this invention provides a combined pressure warning cap that can automatically issue alerts when pressure changes occur without manual intervention.

[0006] The technical solution is: a combined pressure warning cap, including a cap body, an elastic pad, a compression block, a sleeve, a warning component, and a clamping component. The elastic pad is connected to the inner side of the upper part of the cap body, and the compression block is snapped into the middle of the cap body. The compression block is in contact with the elastic pad. The sleeve is connected to the upper side of the compression block. The sleeve is provided with a warning component that can warn of pressure changes. The cap body is provided with a clamping component that can fix the sleeve.

[0007] Furthermore, the cap is equipped with multiple anti-slip blocks.

[0008] Furthermore, the warning assembly includes a piston rod, a connecting frame, springs, a rotating frame, torsion springs, control buttons, impact detonators, and an alarm light. The piston rod is slidably connected to the sleeve, and the connecting frame is connected to the upper part of the piston rod. Multiple springs are connected between the connecting frame and the sleeve. Multiple rotating frames are rotatably connected to the lower part of the piston rod. Multiple torsion springs are connected between the rotating frames and the piston rod. Initially, the torsion springs are in a deformed state. Multiple control buttons are provided on the upper part of the piston rod. Multiple impact detonators are connected inside the sleeve. The rotating frames and impact detonators are in a pressing fit. An alarm light is connected to the upper side of the piston rod. The control buttons and the alarm light are electrically connected.

[0009] Furthermore, the clamping assembly includes a screw and a clamping plate. The upper sides of both the left and right sides of the cap are threaded with screws, and clamping plates are rotatably connected to the screws. The clamping plates are engaged with the sleeve.

[0010] Furthermore, each screw is equipped with a knob.

[0011] Furthermore, all clamping plates are arc-shaped.

[0012] The beneficial effects of this utility model are as follows: When the piston rod moves, it drives the rotating frame to move, causing the rotating frame to strike the knocking plate, which then emits an audible alert. When the pressure inside the pipeline increases to a certain level, the piston rod moves outward to its limit, at which point the torsion spring returns to its original position, and the rotating frame rotates to press the control button, causing the alarm light to illuminate. This achieves the effect of automatically issuing a reminder when the pressure changes, without the need for manual intervention. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] A combined pressure warning cap, such as Figures 1-4 As shown, it includes a cap body 1, an elastic pad 2, a compression block 3, a sleeve 4, a warning component, and a clamping component. The elastic pad 2 is connected to the upper inner side of the cap body 1. The cap body 1 is provided with eight anti-slip blocks for easy tightening. The compression block 3 is snapped into the middle of the cap body 1. The compression block 3 is in contact with the elastic pad 2. The sleeve 4 is connected to the upper side of the compression block 3. The sleeve 4 is provided with a warning component. The cap body 1 is provided with a clamping component.

[0020] like Figures 1-4 As shown, the warning assembly includes a piston rod 5, a connecting frame 6, a spring 7, a rotating frame 8, a torsion spring 9, a control button 10, a collision sounder 11, and an alarm light 14. The piston rod 5 is slidably connected to the sleeve 4. The connecting frame 6 is connected to the upper part of the piston rod 5. Three springs 7 are connected between the connecting frame 6 and the sleeve 4. Three rotating frames 8 are rotatably connected to the lower part of the piston rod 5. Each rotating frame 8 is connected to the piston rod 5 with two torsion springs 9. Initially, the torsion springs 9 are in a deformed state. Three control buttons 10 are provided on the upper part of the piston rod 5. Multiple collision sounders 11 are connected inside the sleeve 4. The rotating frame 8 and the collision sounders 11 are pressed together. An alarm light 14 is connected to the upper side of the piston rod 5. The control button 10 and the alarm light 14 are electrically connected.

[0021] like Figure 1 As shown, the clamping assembly includes a screw 12 and a clamping plate 13. The upper sides of both the left and right sides of the cap body 1 are threadedly connected to the screw 12. Each screw 12 is equipped with a knob for easy gripping. Each screw 12 is rotatably connected to the clamping plate 13. The clamping plates 13 are all arc-shaped to facilitate clamping the sleeve 4. The clamping plates 13 are engaged with the sleeve 4.

[0022] When using this utility model, first, insert the sleeve 4 through the cap body 1 from bottom to top, then rotate the screw 12 to make the clamping pieces 13 close to each other to clamp the sleeve 4. At this time, the extrusion block 3 extrudes the elastic pad 2 to enhance the sealing effect of the elastic pad 2 on the cap body 1. Then, install the cap body 1 on the pipe joint of the air conditioning equipment.

[0023] When the pressure inside the pipeline increases, the piston rod 5 moves outward, causing the connecting bracket 6 to move outward and the spring 7 to stretch. When the pressure inside the pipeline decreases, the spring 7 rebounds, causing the piston rod 5 and the connecting bracket 6 to return to their original positions. As the piston rod 5 moves, it also causes the rotating bracket 8 to move. Under the action of the torsion spring 9, the rotating bracket 8 strikes the impact rattle 11, which emits an audible alert. When the pressure inside the pipeline increases to a certain level, the piston rod 5 moves outward to its limit. At this time, the torsion spring 9 returns to its original position, and the rotating bracket 8 rotates to press the control button 10, causing the alarm light 14 to illuminate. This provides an automatic alert when the pressure changes, without the need for manual intervention.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
