[0001] This utility model relates to the field of saturated vapor pressure constant temperature testing technology, specifically to a gasoline saturated vapor pressure constant temperature testing device. Background Technology
[0002] A constant-temperature testing device for detecting the saturated vapor pressure of gasoline is a device used to measure the saturated vapor pressure of gasoline. Saturated vapor pressure is the pressure of vapor in equilibrium with a solid or liquid under closed conditions and at a certain temperature. Different substances have different saturated vapor pressures at the same temperature.
[0003] Currently, before testing, the testing equipment needs to be connected to the gasoline storage tank, and then the gasoline storage tank is placed in a constant temperature bath so that the testing equipment can perform a saturated vapor pressure test on the gasoline. Various special situations may occur during the test, such as a lack of stable support for the gasoline tank, and the inconvenience of placing and removing the gasoline tank within the constant temperature bath. Therefore, there is an urgent need to design a constant temperature testing device for gasoline saturated vapor pressure to solve these problems. Summary of the Invention
[0004] The purpose of this invention is to provide a gasoline saturated vapor pressure constant temperature testing device to address the aforementioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A gasoline saturated vapor pressure constant temperature testing device includes a housing, a water bath at the top of the housing, a cover plate rotatably fitted to the top of the water bath, a fixing assembly between the water bath and the cover plate, a pressure gauge, a glass thermometer, and testing instruments mounted on the top of the housing, a control panel on one side of the housing, a connecting hose and a water inlet inside the water bath, a sliding frame slidably fitted inside the water bath, the bottom of the sliding frame elastically fitted to the bottom of the water bath, the sliding frame being U-shaped, the bottom of the cover plate abutting against the top of the sliding frame, a placement groove formed on the bottom of the inner wall of the sliding frame, two rotating rods rotatably fitted inside the sliding frame, an arc-shaped clamping block at the top of each rotating rod, and the two rotating rods being symmetrically distributed.
[0007] Furthermore, a fixing groove is provided on the periphery of the top of the water bath, and a locking block is installed on both sides of the cover plate. The fixing groove has two slots opposite to the two locking blocks, and the locking blocks and the fixing groove are slidably engaged.
[0008] Furthermore, a pull block is installed on the top of the cover plate, and a wire frame is installed on the top of the box body. The wire frame is U-shaped and bent at the top, and the pull block corresponds to the wire frame.
[0009] Furthermore, sliding grooves are provided on both sides of the water bath, and the two sides of the movable frame are respectively slidably engaged with the two sliding grooves. Two springs are installed between the bottom of the movable frame and the bottom of the water bath, and the two springs are symmetrically distributed.
[0010] Furthermore, a protective pad is installed at the bottom of the cover plate, and the protective pad corresponds to the placement groove.
[0011] Furthermore, the bottom of the box is equipped with four self-locking casters, which are arranged in a rectangular array, and a handrail is installed on one side of the box.
[0012] In the above technical solution, the gasoline saturated vapor pressure constant temperature testing device provided by this utility model has the following beneficial effects:
[0013] The rotating rod allows the gasoline canister to be placed onto the placement slot within the movable frame. The cover plate then presses against the movable frame and placement slot into the water bath, causing the rotating rod to rotate against the bottom of the water bath. This allows the rotating rod to drive the arc-shaped clamping block to securely support the canister, reducing the impact on the canister in special circumstances. After the cover plate is removed by adjusting the fixing components, the movable frame can be moved upwards via elastic engagement, allowing the canister to be moved out of the water bath, facilitating the placement and removal of the gasoline canister. When the movable frame moves upwards, the rotating rod automatically releases its grip on the canister. Attached Figure Description

[0023] Referring to Figure 2, in this embodiment, a fixing groove 17 is provided on the periphery of the top of the water bath 2. A locking block 18 is installed on both sides of the cover plate 3. Two slots 19 are provided on the fixing groove 17, opposite to the two locking blocks 18. The locking blocks 18 slide in conjunction with the fixing groove 17. By using the locking blocks 18, the locking blocks 18 can be aligned with the slots 19. Pressing the cover plate 3 moves the locking blocks 18 into the slots 19. Then, rotating the cover plate 3 moves the locking blocks 18 along the fixing groove 17, thus fixing the cover plate 3.
[0024] Referring to Figure 2, in this embodiment, a pull block 15 is installed on the top of the cover plate 3, and a wire frame 16 is installed on the top of the housing 1. The wire frame 16 is U-shaped and bent at the top, and the pull block 15 corresponds to the wire frame 16. By using the pull block 15, the cover plate 3 can be moved by pulling the pull block 15.

[0025] Referring to Figure 3, in this embodiment, the water bath 2 has sliding grooves 20 on both sides. The two sides of the movable frame 9 are respectively slidably engaged with the two sliding grooves 20. Two springs 21 are installed between the bottom of the movable frame 9 and the bottom of the water bath 2, and the two springs 21 are symmetrically distributed. Through the sliding grooves 20, when the movable frame 9 moves downward, it will move stably along the two sliding grooves 20, and the movable frame 9 will compress the two springs 21. After the cover plate 3 is removed, the springs 21 will drive the movable frame 9 to move upward.
[0026] Referring to Figure 3, a protective pad 22 is installed at the bottom of the cover plate 3 in this embodiment, and the protective pad 22 corresponds to the placement groove 10.

Then, connect the test connecting hose 23 to the container, adjust the control panel 8 to supply constant temperature water to the water bath 2, and then align the cover plate 3 with the moving frame 9, so that the cover plate 3 presses the moving frame 9 downwards. The moving frame 9 will then drive the container into the water bath 2. The rotating rods 11 will then connect the container. When the device touches the bottom of the water bath 2, it will rotate due to the pressure, causing the rotating rod 11 to drive the arc-shaped clamping block 12 to fix the tank. After the moving frame 9 is fully inserted into the water bath 2, the fixing component 4 is adjusted to fix the cover plate 3, so that the cover plate 3 fixes the moving frame 9. Then, the control panel 8 is adjusted to perform the test. The pressure gauge 5, glass thermometer 6, testing instrument 7 and control panel 8 will display the relevant test data. After the test is completed, the cover plate 3 is opened, and the moving frame 9 will move upward through the elastic cooperation, so that the moving frame 9 drives the tank to move out of the water bath 2.
