Description
Technical Field
[0001] The utility model relates to a pressure container with a protective structure, belonging to the technical field of pressure containers. Background Art
[0002] Pressure vessels are a broad category that includes a variety of equipment used to contain gas or liquid and can withstand a certain pressure. Common pressure vessels include: gas tanks, reactors, boilers and gas cylinders.
[0003] During the use of existing gas cylinder pressure vessels, in order to ensure that the valves will not be damaged and leak due to accidental strong contact during transportation, protective structures are usually installed to surround the valves to a certain extent. However, the protective structures commonly used at present are mostly semi-enclosed designs. Although this design can provide a certain protection effect, during the actual transportation process, the valves may still come into contact with the outside world, posing a potential risk of damage. Therefore, there is still room for improvement in the protection safety factor of pressure vessels.
[0004] Therefore, it is necessary to design a new type of pressure vessel with a protective structure, which can automatically form a fully enclosed protection during movement to ensure the safety of the switch valve. During normal use, the protective parts will automatically reassemble into a semi-enclosed structure to avoid interfering with the switch valve operation, so as to meet the safety and convenience requirements of the pressure vessel in transportation and use. Utility Model Content
[0005] Therefore, the purpose of the present invention is to provide a pressure vessel with a protective structure that can ensure safety during movement and convenience during use.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a pressure vessel with a protective structure, specifically comprising: a pressure tank body, a switch valve is provided at the center of the top of the pressure tank body; a basic protective part is fixedly installed on the top of the pressure tank body; a reinforced protective part is installed on the outer wall of the basic protective part; a driven semi-screw groove is provided on the outer wall of the reinforced protective part; a support base is fixedly installed on the circumferential outer wall of the pressure tank body; a brake screw is rotatably installed at the center of the front side of the support base; a downward pressure slide groove is provided inside the support base; the downward pressure slide groove is provided with a sliding installation inside There is a brake pressure rod; an embedded baffle is fixedly installed on the circumferential outer wall of the brake pressure rod; the embedded baffle is also slidably installed inside the downward pressure slide; one end of the return spring is embedded in the bottom of the embedded baffle; the other end of the return spring is embedded in the bottom of the downward pressure slide; a universal wheel body is also rotatably installed on the bottom of the support base; a transmission slide frame is also slidably installed on the circumferential outer wall of the pressure tank body; the transmission slide frame is located above the pressure tank body; push slide rods are fixedly installed on the left and right sides of the top of the transmission slide frame; the inner end of the push slide rod is fixedly installed with a push boss.
[0007] The basic protective part has an arc-shaped structure; the reinforced protective part has an arc-shaped structure; the driven semi-screw groove has a semi-helical structure; and the brake pressure rod has a cylindrical structure.
[0008] The embedded baffle is a disc-shaped structure; the universal wheel body is located below the brake pressure rod; and the transmission slide frame is also connected to the brake screw rod through screw threads.
[0009] The inner end of the pushing boss is a hemispherical structure; the hemispherical structure of the pushing boss is also installed inside the driven half screw groove, and the pushing boss slides along the driven half screw groove.
[0010] The transmission slide frame is also fixedly connected to the top end of the brake pressure rod; when the transmission slide frame moves downward, it also moves downward with the brake pressure rod.
[0011] After the brake pressure rod moves downward, the bottom end of the brake pressure rod will contact the wheel wall of the universal wheel body; when the transmission slide frame descends, it will also bring the push slide rod and the push protrusion down with it.
[0012] When the pushing boss descends, the pushing boss cooperates with the driven half-screw groove of the semi-helical structure to rotate relatively outward with the reinforcing protective piece.
[0013] By adopting the above technical solution, the pressure vessel with a protective structure of the utility model can rotate the reinforced protective parts inward relative to each other, so that the two reinforced protective parts can be docked and form a full-coverage protection system together with the basic protective parts, thereby providing a more stringent safety protection for the switch valve on the pressure tank body during movement. Compared with the traditional semi-enclosed protection structure, the protection safety factor of this design is significantly improved. In addition, when the universal wheel body is released to brake and prepare to move the pressure tank body, the pressure vessel can automatically trigger the reinforced protective parts and the basic protective parts to form a full-enclosed structure to protect the switch valve. When the universal wheel body is braked to prepare for normal use of the pressure tank body, the reinforced protective parts and the basic protective parts can be automatically recombined into a semi-enclosed structure to avoid any interference with the normal operation of the switch valve. This ensures the safety of the switch valve of the pressure vessel during transportation and movement, and ensures that the existence of the protective structure will not cause inconvenience to the operator during normal use.

[0020] The present invention will be further described in detail below through the accompanying drawings and specific implementation methods.
[0021] Example 1:
[0022] like Figure 1-6As shown, the utility model is a pressure vessel with a protective structure, comprising: a pressure tank body 1, a switch valve is provided at the center of the top of the pressure tank body 1; a basic protective part 2 is fixedly installed on the top of the pressure tank body 1; a reinforcing protective part 3 is slidably installed on the outer wall of the basic protective part 2; a driven semi-screw groove 4 is provided on the outer wall of the reinforcing protective part 3; a supporting base 5 is fixedly installed on the circumferential outer wall of the pressure tank body 1; a brake screw rod 6 is rotatably installed at the center of the front side of the supporting base 5; a downward pressing groove 7 is provided inside the supporting base 5; a brake pressure rod 8 is slidably installed inside the downward pressing groove 7; the brake An embedded baffle 9 is fixedly mounted on the circumferential outer wall of the pressure-stop rod 8; the embedded baffle 9 is also slidably mounted inside the downward-pressing chute 7; one end of a restoring spring 10 is embedded and mounted on the bottom of the embedded baffle 9; the other end of the restoring spring 10 is embedded and mounted on the bottom of the downward-pressing chute 7; a universal wheel body 11 is also rotatably mounted on the bottom of the support base 5; a transmission slide frame 12 is also slidably mounted on the circumferential outer wall of the pressure tank body 1; the transmission slide frame 12 is located above the pressure tank body 1; push slide bars 13 are fixedly mounted on the left and right sides of the top of the transmission slide frame 12; and a push boss 14 is fixedly mounted on the inner end of the push slide bar 13.
[0023] When the pressure tank body 1 is to be moved and transported, the brake screw rod 6 is manually rotated to make the brake screw rod 6 move upward with the transmission slide frame 12 by rotating, so that the transmission slide frame 12 uses the upward movement to lift the brake pressure rod 8, so that the brake pressure rod 8 cancels the brake on the universal wheel body 11, thereby facilitating the position transfer of the pressure tank body 1 through the universal wheel body 11, and when the transmission slide frame 12 moves upward, the transmission slide frame 12 will move the push slide rod 13 and the push boss 14 upward, so that the push boss 14 moves upward to cooperate with the driven half screw groove 4 of the spiral structure to drive the reinforced protective part 3 to rotate inward relative to each other, so that the two reinforced protective parts 3 are docked and together with the basic protective part 2 to form a fully enclosed protective structure, thereby using the fully enclosed protective structure to protect the switch valve on the pressure tank body 1 during movement. Compared with the traditional semi-enclosed protective structure, the safety factor of the pressure vessel protective structure is higher.
[0024] Based on the first embodiment, the second embodiment:
[0025] The basic protective part 2 has an arc-shaped structure; the reinforced protective part 3 has an arc-shaped structure; the driven semi-screw groove 4 has a semi-spiral structure; the brake pressure rod 8 has a cylindrical structure; the embedded baffle 9 has a disc-shaped structure; the universal wheel body 11 is located below the brake pressure rod 8; the transmission slide frame 12 is also connected to the brake screw 6 through screw threads; the inner end of the push boss 14 has a hemispherical structure; the hemispherical structure of the push boss 14 is also slidably installed inside the driven semi-screw groove 4.
[0026] After the pressure tank body 1 moves to the desired position, the brake screw 6 is reversed to move it downward with the transmission slide frame 12 and the brake pressure rod 8, so that the bottom end of the brake pressure rod 8 contacts the wheel wall of the universal wheel body 11 by moving downward, so that the universal wheel body 11 is braked, and when the transmission slide frame 12 descends, the transmission slide frame 12 will also move downward with the push slide bar 13 and the push boss 14, so that the push boss 14 moves downward to cooperate with the driven half groove 4 of the spiral structure to rotate relative to the reinforced protective part 3 outward, so that the two reinforced protective parts 3 are spaced apart and overlap with the basic protective part 2, thereby converting the basic protective part 2 and the reinforced protective part 3 into a semi-enclosed structure, which is convenient for users to operate the switch valve.
[0027] Based on the second embodiment, the third embodiment:
[0028] The transmission slide frame 12 is also fixedly connected to the top end of the brake pressure rod 8; when the transmission slide frame 12 moves downward, it will also move downward with the brake pressure rod 8; after the brake pressure rod 8 moves downward, the bottom end of the brake pressure rod 8 will contact the wheel wall of the universal wheel body 11; when the transmission slide frame 12 descends, it will also bring the push slide bar 13 and the push boss 14 down; when the push boss 14 descends, the push boss 14 will cooperate with the driven half screw groove 4 of the semi-helical structure to rotate outward relative to the reinforced protective part 3.
[0029] When the universal wheel body 11 is released to prepare to move the pressure tank body 1, the reinforced protective part 3 and the basic protective part 2 are automatically formed into a fully enclosed structure to protect the switch valve through the cooperation of multiple structures. When the universal wheel body 11 is stopped to prepare for normal use of the pressure tank body 1, the reinforced protective part 3 and the basic protective part 2 are automatically overlapped through the cooperation of multiple structures, thereby avoiding the reinforced protective part 3 interfering with the normal use of the switch valve by the user.
[0030] The working principle of this embodiment is as follows: when the pressure tank body 1 needs to be moved and transported, the operator can manually rotate the brake screw rod 6 to drive the transmission slide frame 12 to rise along the predetermined trajectory. This action in turn drives the brake pressure rod 8 to move upward, releasing the brake on the universal wheel body 11, so that the pressure tank body 1 can be easily transferred with the help of the universal wheel body 11. During this process, the rise of the transmission slide frame 12 also synchronously drives the push slide rod 13 and the push boss 14 upward. The push boss 14 interacts with the driven half screw groove 4 with a spiral structure, causing the reinforced protective part 3 to rotate inward relative to each other until the two reinforced protective parts 3 are docked and together with the basic protective part 2 to form a fully wrapped protective system, thereby providing a more stringent safety protection for the switch valve on the pressure tank body 1 during movement;
[0031] Once the pressure tank body 1 is moved to the predetermined position, the operator only needs to rotate the brake screw 6 in the opposite direction to drive the transmission slide frame 12 and the brake pressure rod 8 downward. The bottom end of the brake pressure rod 8 will contact and press the wheel wall of the universal wheel body 11 to achieve effective braking. At the same time, the descent of the transmission slide frame 12 will also drive the push slide bar 13 and the push boss 14 to move downward synchronously. The push boss 14 will interact with the driven half screw groove 4 again, prompting the reinforced protective part 3 to rotate outward relative to each other until the two reinforced protective parts 3 are separated and recombined with the basic protective part 2 to form a semi-enclosed structure, which is convenient for the operator to perform various operations on the switch valve.
[0032] By adopting the above technical solution, the pressure vessel with a protective structure of the present invention rotates the reinforced protective parts 3 inward relative to each other, so that the two reinforced protective parts 3 are docked and together with the basic protective part 2 form a fully wrapped protective system, thereby providing a more stringent safety protection for the switch valve on the pressure tank body 1 during movement. Compared with the traditional semi-enclosed protective structure, the protection safety factor of this design is significantly improved. In addition, when the universal wheel body 11 is released to brake and prepare to move the pressure tank body 1, the pressure vessel can automatically trigger the reinforced protective parts 3 and the basic protective part 2 to form a fully enclosed structure to protect the switch valve. When the universal wheel body 11 is braked to prepare for normal use of the pressure tank body 1, the reinforced protective parts 3 and the basic protective part 2 can be automatically recombined into a semi-enclosed structure to avoid any interference with the normal operation of the switch valve. This ensures the safety of the switch valve of the pressure vessel during transportation and movement, and ensures that the existence of the protective structure will not cause inconvenience to the operator during normal use.
[0033] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
