Description

Technical Field

[0001] This invention relates to the field of trigger valve technology, specifically to a device for quickly replacing water-soluble paper inside a trigger valve. Background Technology

[0002] A vehicle-mounted lifebuoy is a type of water rescue equipment, usually placed in a vehicle. Before falling into the water, the lifebuoy is in a contracted state. When it falls into the water, the water dissolves the water-soluble paper at the opening of the inflation bottle, opening the inflation bottle and automatically inflating the lifebuoy to allow the person in the water to quickly save themselves.

[0003] The water-soluble paper inside the trigger valve is disposable; it dissolves upon contact with water. For example... Figure 5 The diagram shows a trigger valve with an annular mounting platform inside. Water-soluble paper is adhered to the mounting platform. Because the trigger valve is small and the water-soluble paper is hidden inside the trigger, it is difficult to replace the water-soluble paper after it melts, thus rendering the trigger valve unusable. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device for quickly replacing water-soluble paper inside a trigger valve, thereby solving the problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A quick-change device for water-soluble paper inside a trigger valve includes a cylinder, a shelf slidably connected inside the cylinder, a shelf groove provided on the shelf, a first driving device on the cylinder for driving the shelf to slide inside the cylinder, an installation groove communicating with one side of the cylinder at the top, a partition plate connected to the lower part of the installation groove, a strip hole opened on the partition plate, an installation seat slidably connected inside the installation groove, a glue rod detachably connected to the installation seat, and a second driving device inside the installation groove for driving the installation seat to move into the inner cavity of the cylinder.

[0007] Preferably, the first driving device includes an adjusting rod threaded into the cylinder and a handle connected to the lower end of the adjusting rod, with the upper end of the adjusting rod connected to the bottom surface of the shelf.

[0008] The above technical solution involves rotating the handle to cause the adjusting rod to rotate inside the cylinder, which in turn causes the placement plate to rise inside the cylinder, so that the water-soluble paper is adhered to the trigger valve.

[0009] Preferably, the second drive device includes a motor located in the lower part of the mounting groove, a drive shaft connected to the motor via a coupling, a first bevel gear connected to the drive shaft, a lead screw rotatably connected to the mounting groove, a slide rod threaded to the lead screw, and a second bevel gear connected to the lead screw. The first bevel gear meshes with the second bevel gear, and the slide rod is slidably connected to the slot, with its upper end connected to the mounting base.

[0010] The above technical solution involves starting the motor and driving the lead screw to rotate. Since the slide rod is slidably connected to the slot in the partition, the lead screw rotates and drives the slide rod to slide in the slot, thereby moving the mounting base and the glue rod on it into the cylinder. The glue rod reaches one side of the cylinder, and then the cylinder is inserted into the trigger valve so that the glue rod contacts the mounting platform inside the trigger valve. Rotating the cylinder then allows the glue on the glue rod to be applied to the mounting platform.

[0011] Preferably, the mounting base is provided with a screw hole, and the lower end of the glue rod is provided with a screw rod, which is threaded into the screw hole of the mounting base through the screw rod.

[0012] In the above technical solution, the glue rod is connected to the screw hole of the mounting base via a screw thread, which facilitates the replacement of the glue rod.

[0013] Preferably, the top of the cylinder is also connected to a gasket of the same height as the glue rod, and the gasket is symmetrical to the glue rod.

[0014] The above technical solution, through the use of gaskets, allows the glue stick to remain balanced when applying glue to the mounting platform.

[0015] Preferably, a knob is connected to the outer periphery of the lower end of the cylinder.

[0016] The above technical solution allows the cylinder to be rotated via a knob to apply adhesive to the mounting platform.

[0017] Preferably, a battery is installed in the mounting slot, the battery is electrically connected to the motor, and a cover plate is fastened to the side wall of the cylinder to facilitate battery replacement.

[0018] The above technical solution uses a battery to power the motor. By opening the cover, the battery and the motor can be replaced.

[0019] Preferably, the outer walls of both the handle and the knob are provided with anti-slip texture.

[0020] The above technical solution, through its anti-slip texture, can prevent slippage when turning the handle or knob.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When the water-soluble paper inside the trigger valve is damaged, a new water-soluble paper is placed in the storage slot of the placement plate. Then, the second drive device drives the glue stick to move from the mounting slot into the cylinder, so that the glue stick is located on one side of the inner cavity of the cylinder. Then, the cylinder is inserted into the trigger valve, so that the glue stick contacts the mounting platform. Then, the cylinder is rotated, so that the glue stick rotates and applies glue to the mounting platform. Next, the second drive device drives the glue stick back into the mounting slot. Then, the first drive device drives the placement plate to move upward, so that the water-soluble paper contacts the mounting platform. The placement plate continues to rise to press the water-soluble paper tightly onto the mounting platform, thereby fixing the water-soluble paper with glue, realizing the replacement of the water-soluble paper. After replacement, the water-soluble paper can be stably adhered inside the trigger valve. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figure 1 and Figure 2A quick-change device for water-soluble paper inside a trigger valve includes a cylinder 1, a shelf 2 slidably connected inside the cylinder 1, and a shelf groove on the shelf 2. The cylinder 1 is equipped with a first driving device for driving the shelf 2 to slide within the cylinder. The first driving device includes an adjusting rod 8 threadedly connected inside the cylinder 1 and a handle 9 connected to the lower end of the adjusting rod. The upper end of the adjusting rod 8 is connected to the bottom surface of the shelf 2. Rotating the handle 9 causes the adjusting rod 8 to rotate within the cylinder 1, which in turn causes the shelf 2 to rise within the cylinder 1.

[0033] like Figure 2 , Figure 4 As shown, a mounting groove 3 communicating with the cylinder body is provided on the top of one side of the cylinder body 1. A partition plate 4 is connected to the lower part of the mounting groove 3. A strip hole 5 is opened on the partition plate 4. A mounting seat 6 is slidably connected in the mounting groove 3. A glue rod 7 is detachably connected to the mounting seat 6. Specifically, the mounting seat 6 is provided with a screw hole. A screw rod 15 is provided at the lower end of the glue rod 7. The glue rod 7 is threadedly connected to the screw hole of the mounting seat 6 through the screw rod 15, which facilitates the replacement of the glue rod.

[0034] like Figure 2 and Figure 3 As shown, the mounting groove 3 is equipped with a second driving device that drives the mounting base 6 to move into the inner cavity of the cylinder 1. The second driving device includes a motor 10 located in the lower part of the mounting groove 3, a transmission shaft connected to the motor via a coupling, a first bevel gear 11 connected to the transmission shaft, a lead screw 12 rotatably connected in the mounting groove, a slide rod 13 threadedly connected to the lead screw, and a second bevel gear 14 connected to the lead screw. The first bevel gear 11 and the second bevel gear 14 mesh, and the slide rod 13 is slidably connected in the slotted hole 5, with its upper end connected to the mounting base 6. When the motor 10 is started, the lead screw 12 is driven to rotate. Since the slide rod 13 is slidably connected in the slotted hole 5 of the partition 4, the rotation of the lead screw 12 drives the slide rod 13 to slide in the slotted hole 5, thereby driving the mounting base 6 and the glue rod 7 on it to move into the cylinder 1, so that the glue rod 7 reaches one side of the cylinder 1.

[0035] In this embodiment, a knob 17 is connected to the outer periphery of the lower end of the cylinder 1. The cylinder 1 can be easily rotated by the knob 17.

[0036] like Figure 1 As shown, a gasket 16 of the same height as the glue rod 7 is also connected to the top of the cylinder 1, and the gasket 16 is symmetrical to the glue rod 7. The gasket 16 helps to keep the glue rod 7 balanced when applying glue to the mounting platform 22.

[0037] In this embodiment, a battery 18 is installed in the mounting slot 3, and the battery 18 is electrically connected to the motor 10. A cover plate 19 is fastened to the side wall of the cylinder 1 to facilitate the replacement of the battery 18. The motor 10 is powered by the battery 18, and the battery and motor can be replaced by opening the cover plate 19.

[0038] The working principle of this embodiment is as follows: Figure 6 As shown, when the water-soluble paper 21 in the trigger valve 20 is damaged, a new water-soluble paper 21 is placed in the storage slot of the storage plate 2. Then, the motor 10 is started to drive the glue rod 7 from the mounting slot 3 into the cylinder 1, so that the glue rod 7 is located on one side of the inner cavity of the cylinder 1. Then, the cylinder 1 is inserted into the trigger valve 20 so that the glue rod 7 contacts the mounting platform 22. Then, the cylinder 1 is rotated so that the glue rod 7 rotates and applies glue to the mounting platform 22. Then, the motor 10 is controlled to rotate in the opposite direction so that the glue rod 7 returns to the mounting slot 3. Then, the handle 9 is turned to drive the storage plate 2 to move upward so that the water-soluble paper 21 contacts the mounting platform 22. The storage plate 2 is then driven to rise to press the water-soluble paper 21 tightly onto the mounting platform 22, thereby fixing the water-soluble paper 21 with glue and realizing the replacement of the water-soluble paper.

[0039] Example 2

[0040] Based on Embodiment 1, the outer walls of both the handle 9 and the knob 17 are provided with anti-slip textures. These textures prevent slippage when turning the handle or knob.
