Abstract
Description
Technical Field
[0001] This utility model relates to the field of breathing tubing technology, and more specifically, to a foldable oil tank breathing ventilation tube. Background Technology
[0002] The breather vent pipe for oil tanks stabilizes the pressure inside and outside the tank by connecting the air inside and outside. When the oil level in the tank decreases, air flows into the tank through the breather vent pipe to maintain stable pressure; conversely, when the oil level increases, air flows out of the tank through the breather vent pipe to maintain stable pressure. This maintains pressure balance inside and outside the tank, preventing safety issues and avoiding abnormal pressure and malfunctions in oil intake or output. Foldable breather pipes are now appearing on the market.
[0003] Its drawback is that the folding height needs to be adjusted according to the actual situation during the folding process. Most existing technologies use bricks as a means of implementation, which is not only inconvenient but also cannot guarantee safety. Utility Model Content
[0004] To address the issue of the folding height problem in the maintenance of oil tank breathing vent pipes, the purpose of this utility model is to provide a foldable oil tank breathing vent pipe with adjustable support rod height, thereby ensuring safe and convenient maintenance.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a foldable oil tank breathing vent pipe, comprising an upper rotating part, a folding device, and a lower fixed part. The upper rotating part includes a flame-arresting mechanical breathing valve and an upper vent pipe. A support base is fixedly provided on the outer edge of the upper vent pipe. The support base is rotatably connected to a support rod via a support rotating shaft. The support rod can rotate around the support rotating shaft. The support rod includes an upper support rod and a lower support rod fixedly connected to the support rotating shaft. Stop blocks are evenly provided on the lower part of the upper support rod. The upper support rod is inserted into the lower support rod. The lower support rod is provided with a sliding groove and a stop groove, the purpose of which is to facilitate the movement and stopping of the stop blocks.
[0006] Preferably, the support base has an "n" shaped cross section, including a top surface and two side surfaces, with the support rotation shaft passing through the two side surfaces.
[0007] More preferably, the tail end of the lower support rod is hemispherical, the purpose of which is to form a fixed groove at the tail end under the action of gravity.
[0008] More preferably, the upper end of the handle of the lower support rod is tapered, with a smaller top and a larger bottom, and a drainage hole is provided at the bottom of the handle to allow for quick drainage during rainy weather.
[0009] More preferably, a fixing bracket is provided below the support base, the fixing bracket is welded to the outer edge of the upper ventilation pipe, and the fixing bracket is provided with a slot for engaging the support rod.
[0010] Preferably, the folding device is a bowl-shaped interface piece that is symmetrical and can be sealed to each other. An upper rotating hinge is fixedly provided on the outer edge of the upper bowl-shaped interface piece, and a lower rotating hinge is provided on the outer edge of the lower bowl-shaped interface piece. Both the upper and lower rotating hinges are provided with through holes for inserting a rotating shaft. The upper and lower bowl-shaped interface pieces can rotate around the rotating shaft.
[0011] Preferably, one end of the lower fixing part is connected to the oil tank, and the other end is fixedly connected to the lower bowl-shaped interface piece.
[0012] The practical principle of this utility model is as follows:
[0013] When the oil tank's breathing vent pipe needs maintenance or repair, the folding device operates, rotating the support rod out of the fixed bracket. The folding height is then fixed by external force. Subsequently, by rotating the lower support rod, the stop block is moved from the stop groove into the slide groove. The upper and lower support rods can then move relative to each other. When the stop block moves to the required position, the lower support rod is rotated to set the stop block into the corresponding stop groove, thus completing the support work. After the maintenance is completed, the previous process is reversed.
[0014] In summary, this utility model has the following beneficial effects:
[0015] Firstly, the upper support rod is inserted into the lower support rod and placed in stop slots at different heights via stop blocks, thereby adjusting the relative length of the upper and lower support rods and thus adjusting the overall length of the support rod to ensure that the support rod can be used for different folding heights.
[0016] Secondly, the upper part of the handle is tapered, with a smaller top and a larger bottom, to ensure that rainwater does not adhere to the handle or the lower support rod. Attached Figure Description

[0028] See details Figure 1-6A foldable oil tank breathing vent pipe includes an upper rotating part, a folding device 1, and a lower fixed part 2. The upper rotating part includes a flame-arresting mechanical breathing valve 3 and an upper vent pipe 4. A support seat 5 is fixedly installed on the outer edge of the upper vent pipe 4. The support seat 5 is rotatably connected to a support rod through a support rotating shaft 6. The support rod can support the rotating shaft 6 to rotate around the axis. The support rod includes an upper support rod 7 and a lower support rod 8 fixedly connected to the support rotating shaft 6. Stop blocks 701 are evenly arranged on the lower part of the upper support rod 7. The upper support rod 7 is inserted into the lower support rod 8. The lower support rod 8 is provided with a sliding groove 801 and a stop groove 802, the purpose of which is to facilitate the movement of the stop blocks 701 and to fix them.
[0029] In this embodiment, there are three stop blocks 701 and seven stop grooves 802. The tube body at the bottom of the stop groove 802 is provided with reinforcing ribs to increase its load-bearing capacity and prevent deformation caused by long-term load-bearing.
[0030] Specifically, the support base 5 has an "n" shaped cross section, including an upper top surface 501 and two side surfaces 502, with a support rotation shaft 6 running through the two side surfaces 502.
[0031] Through the above technical solution, the top surface acts as a stop, which is intended to prevent the support rod from rotating towards the top surface, thereby causing the upper rotating part to shift in position.
[0032] Specifically, the tail end of the supporting rod 8 is hemispherical, the purpose of which is to form a fixed groove at the tail end under the action of gravity.
[0033] Specifically, the upper part of the handle of the lower support rod 8 is a cone shape with a smaller top and a larger bottom, and a drainage hole 803 is provided at the bottom of the handle to allow rainwater to drain quickly during rainy weather.
[0034] Specifically, a fixing bracket 9 is provided below the support base 5. The fixing bracket 9 is welded to the outer edge of the upper ventilation pipe 4, and the fixing bracket 9 is provided with a slot for locking the support rod.
[0035] Specifically, the folding device 1 is a bowl-shaped interface 101 that is symmetrical and can be sealed to each other. An upper rotating hinge is fixedly provided on the outer edge of the upper bowl-shaped interface 101, and a lower rotating hinge is provided on the outer edge of the lower bowl-shaped interface 101. Both the upper and lower rotating hinges are provided with through holes for inserting the rotating shaft. The upper and lower bowl-shaped interface 101 can rotate around the rotating shaft.
[0036] Specifically, one end of the lower fixing part 2 is connected to the oil tank, and the other end is fixedly connected to the lower bowl-shaped interface piece 101.
[0037] The principle of this embodiment is as follows: When the breathing vent pipe of the oil tank needs maintenance or repair, the folding device 1 works to rotate and remove the support rod from the fixed bracket 9. The folding height is fixed by other external forces. Then, by rotating the lower support rod 8, the stop block 701 is moved from the stop groove 802 into the slide groove 801. The upper support rod 7 and the lower support rod 8 can move relative to each other. When the stop block 701 moves to the required position, the lower support rod 8 is rotated to set the stop block 701 in the corresponding stop groove 802 to complete the support work. After the maintenance is completed, the previous process is reversed.
[0038] The upper support rod 7 is inserted into the lower support rod 8 and placed in the stop grooves 802 at different heights by the stop block 701, so that the upper support rod 7 and the lower support rod 8 are adjusted relative to each other, thereby adjusting the length of the support rod as a whole, so as to ensure that the support rod can be used for different folding heights.
[0039] The upper part of the handle is tapered, with a smaller top and a larger bottom, to ensure that rainwater does not adhere to the handle or the lower support rod 8.
[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
