Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology for rubber products, specifically an airtightness testing device for rubber products. Background Technology

[0002] In our daily lives, all kinds of tools and related items are made of various materials, among which rubber is quite common. For example, rubber hoses, which act as the blood vessels of a car and are responsible for transporting various fluids throughout the vehicle, need to undergo airtightness testing after production.

[0003] Chinese patent CN213874839U discloses an airtightness testing device for rubber hose connections, including a testing water tank. A support frame is fixed to the upper surface of the testing water tank, and an electric push rod is fixed to the lower surface of the support frame. A positioning frame is fixed to the end of the electric push rod away from the support frame. This application can quickly detect whether there are leaks in rubber hoses, and the test results are accurate and fast. Moreover, multiple rubber hoses can be tested at once, which greatly improves the testing efficiency. However, the above patent can only test one type of hose. When the hose diameter is different, it cannot be connected to the device, which affects the test and reduces the applicability of the device. Therefore, we propose an airtightness testing device for rubber products. Utility Model Content

[0004] The purpose of this invention is to provide a rubber product airtightness testing device to solve the problem that the existing technology can only test one type of hose, and when the hose diameter is different, it cannot be connected to the device, which affects the test and reduces the applicability of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber product airtightness testing device, comprising a water tank, an L-shaped plate symmetrically fixed to the top of the water tank, an electric telescopic rod fixed to the top inner side of the L-shaped plate, an adjustment mechanism provided at the output shaft end of the electric telescopic rod, a replacement mechanism provided at the bottom of the adjustment mechanism, a fixing block connected to the bottom of the adjustment mechanism through the replacement mechanism, a sealing plug fixed to one side of the fixing block, an air hole penetrating through the middle of one side of the sealing plug located on one side, and an air pipe penetrating through the middle of the other side of the fixing block located on one side.

[0006] Preferably, the replacement mechanism includes sleeves uniformly fixed to the bottom of the adjustment mechanism. The outer side wall of the sleeve is symmetrically provided with slots. A connecting column is fixed to the top center of the fixing block. The connecting column is symmetrically provided with mounting cavities. A connecting spring is fixed to the center of one side of the mounting cavity. A connecting plate is fixed to one end of the connecting spring. A pressing rod is fixed to the bottom of one side of the connecting plate. A locking block is fixed to the top of one side of the connecting plate.

[0007] Preferably, the diameter of the connecting post is equal to the inner diameter of the sleeve, so that the connecting post and the sleeve are connected to each other, and the connecting plate is slidably connected to the inside of the mounting cavity.

[0008] Preferably, both the pressing rod and the locking block pass through the outer side of the connecting column, and both the pressing rod and the locking block are slidably connected to the connecting column. When the pressing rod is pressed, it drives the connecting plate to move, thereby moving the locking block.

[0009] Preferably, the adjusting mechanism includes a mounting plate fixed to the end of the output shaft of the electric telescopic rod. A screw is rotatably driven through the top of the mounting plate via a bearing. A turntable is fixed to the top of the screw. A movable plate is screwed to the outer wall of the screw. A deflection plate is symmetrically rotated inside the movable plate. A U-shaped rod is symmetrically fixed to the bottom of the mounting plate. A slider is symmetrically slidable on the outer side of the U-shaped rod. A connecting seat is fixed to the top of the slider. The sleeve is uniformly fixed to the bottom of the slider.

[0010] Preferably, the top of the mounting plate is symmetrically fixed with sliding rods, and the movable plate slides on the outside of the sliding rods to limit the movement of the movable plate, so that the movable plate moves stably.

[0011] Preferably, the top of the mounting plate is symmetrically provided with through slots, and the deflection plate is located inside the through slots to avoid affecting the deflection of the deflection plate. The deflection plate is rotatably connected to the inside of the connecting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application utilizes a replacement mechanism. By pressing the pressing rod, the connecting plates move closer together, causing the locking blocks to move closer together and disengage from the locking slots. This releases the connection between the connecting column and the sleeve, allowing the fixing block and sealing plug to be disassembled. After installation, pressing the pressing rod again causes the connecting plates to press against the connecting spring, embedding the connecting column inside the sleeve. Loosening the pressing rod and rotating the connecting column allows the locking blocks to align with the slots. The resetting of the connecting spring causes the connecting plates to reset the locking blocks, embedding them in the slots and securing the sealing plug. This facilitates the replacement of sealing plugs according to different rubber hose diameters, enabling testing of various hose models and improving the applicability of the device.

[0014] 2. In this application, by using the setting of the adjustment mechanism, the rotating turntable drives the screw to rotate, which causes the moving plate to move, thereby causing the deflection plate to deflect, and then causing the connecting seat to move, so that the slider slides on the outside of the U-shaped rod, changing the distance between the two sealing plugs. This makes it easy to adjust according to the length of the rubber hose, which facilitates the testing of rubber hoses of different lengths and further improves the applicability of the device.

Detailed Implementation

[0021] 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.

[0022] Example: Figures 1-5 As shown, this utility model provides a technical solution for a rubber product airtightness testing device, including a water tank 100, an L-shaped plate 200 symmetrically fixed to the top of the water tank 100, an electric telescopic rod 300 fixed to the top inner side of the L-shaped plate 200, an adjustment mechanism 500 provided at the end of the output shaft of the electric telescopic rod 300, a replacement mechanism 400 provided at the bottom of the adjustment mechanism 500, a fixing block 600 connected to the bottom of the adjustment mechanism 500 through the replacement mechanism 400, a sealing plug 610 fixed to one side of the fixing block 600, an air hole 611 penetrating through the middle of one side of the sealing plug 610, and an air pipe 620 penetrating through the middle of the other side of the fixing block 600.

[0023] Please see Figure 2 and Figure 3 The replacement mechanism 400 includes sleeves 410 uniformly fixed to the bottom of the adjustment mechanism 500. The outer wall of the sleeves 410 is symmetrically perforated with slots 420. A connecting post 430 is fixed to the top center of the fixing block 600. The connecting post 430 has symmetrically perforated mounting cavities 440 inside. A connecting spring 450 is fixed to the center of one side of the mounting cavity 440. A connecting plate 460 is fixed to one end of the connecting spring 450. A pressing rod 470 is fixed to the bottom of one side of the connecting plate 460, and a locking block 480 is fixed to the top of one side of the connecting plate 460. The diameter of the connecting post 430 is equal to the inner diameter of the sleeve 410. The connecting plate 460 is slidably connected to the inside of the mounting cavity 440. The pressing rod 470 and the locking block 480 both penetrate the outer side of the connecting post 430, and are slidably connected to the connecting post 430. The replacement mechanism 400 utilizes this configuration... By pressing the pressing rod 470, the connecting plates 460 are brought closer together, causing the locking blocks 480 to move closer together and exit the locking block 480 from the locking groove 420. This disconnects the connecting post 430 from the sleeve 410, disassembling the fixing block 600 and the sealing plug 610. After installation, the pressing rod 470 is pressed again, causing the connecting plate 460 to press against the connecting spring 450, embedding the connecting post 430 inside the sleeve 410. The pressing rod 470 is then loosened, and the connecting post 430 is rotated. When the locking block 480 aligns with the locking groove 420, the resetting of the connecting spring 450 causes the connecting plate 460 to reset, embedding the locking block 480 into the locking groove 420, thus fixing the sealing plug 610. This facilitates the replacement of the sealing plug 610 according to the different diameters of the rubber hose, making it convenient to test various types of hoses and improving the applicability of the device.

[0024] Please see Figure 4 and Figure 5The adjusting mechanism 500 includes a mounting plate 510 fixed to the end of the output shaft of the electric telescopic rod 300. A screw 520 is rotatably driven through the top of the mounting plate 510 via a bearing. A turntable 530 is fixed to the top of the screw 520. A movable plate 540 is screwed to the outer wall of the screw 520. A deflecting plate 550 is symmetrically rotated inside the movable plate 540. A U-shaped rod 560 is symmetrically fixed to the bottom of the mounting plate 510. A slider 570 slides symmetrically on the outer side of the U-shaped rod 560. A connecting seat 580 is fixed to the top of the slider 570. Sleeves 410 are evenly fixed to the bottom of the slider 570. A sliding rod 700 is symmetrically fixed to the top of the mounting plate 510. The movable plate 540... 40 slides on the outside of the slide bar 700; the top of the mounting plate 510 is symmetrically provided with through slots, and the deflection plate 550 is located inside the through slots. The deflection plate 550 is rotatably connected to the inside of the connecting seat 580; by using the setting of the adjustment mechanism 500, by rotating the turntable 530, the screw 520 is driven to rotate, causing the moving plate 540 to move, thereby causing the deflection plate 550 to deflect, and then causing the connecting seat 580 to move, so that the slider 570 slides on the outside of the U-shaped rod 560, changing the distance between the two sealing plugs 610, which is convenient to adjust according to the length of the rubber hose, making it convenient to test rubber hoses of different lengths, and further improving the applicability of the device.

[0025] In use, when the diameters of the rubber hoses in the same batch are different, press the pressing rod 470 to move the connecting plates 460 closer together, causing the locking blocks 480 to move closer together and disengage from the locking slots 420. This releases the connection between the connecting post 430 and the sleeve 410, disassembling the fixing block 600 and the sealing plug 610. Then, reinstall the new plug. Press the pressing rod 470 again to press the connecting plate 460 against the connecting spring 450, embedding the connecting post 430 inside the sleeve 410. Loosen the pressing rod 470 and rotate the connecting post 430. When the locking block 480 aligns with the locking slot 420, the resetting of the connecting spring 450 causes the connecting plate 460 to reset, embedding the locking block 480 into the locking slot 420, thus fixing the sealing plug 610. Replace 610, then insert the sealing plug 610 into both ends of the rubber hose. Connect the external air source to the air pipe 620 through the hose. Start the electric telescopic rod 300 to lower the mounting plate 510, which in turn lowers the rubber hose, placing it in the water. Inflate the hose with the external air source, allowing the gas to enter the air hole 611 through the air pipe 620 and into the interior of the rubber hose. Observe whether air bubbles are generated in the water to test the airtightness. When testing rubber hoses of different lengths, rotate the turntable 530 to rotate the screw 520, causing the moving plate 540 to move, which in turn causes the deflection plate 550 to deflect, thereby causing the connecting seat 580 to move, so that the slider 570 slides outside the U-shaped rod 560, changing the distance between the two sealing plugs 610, and adjusting it according to the length of the rubber hose.
