Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a cover structure of an oil-water separator. Background Art

[0002] An oil-water separator is a device for separating a mixture of oil and water, and is usually used to treat industrial wastewater, oil-contaminated water, oil-water mixture, etc. It utilizes the difference in density between oil and water to effectively separate the two by physical and / or chemical methods. It is usually composed of a water inlet, a separation chamber, an oil collection tank, an oil drain port, a water drain port, and other components. For example, a sealing cover structure of a heating type oil-water separator disclosed in the patent with application number CN201921877483.8 includes a cover body, a mounting groove is provided on the top surface of the cover body, and a first positioning hole and a second positioning hole are provided in the mounting groove, which are respectively used to fix a heating tube and a temperature sensor, and the heating tube and the temperature sensor both extend through the cover body to the inside thereof, and the heating tube and the temperature sensor are connected to an external circuit through a connecting wire, and the mounting groove is filled with electronic packaging glue that wraps the heating tube, the temperature sensor and the connecting wire and penetrates into the gap between the first positioning hole and the second positioning hole.

[0003] During the production and use of the existing oil-water separator cover structure, the assembly accuracy of the heating tube is low, resulting in uneven quality of the finished oil-water separator. In addition, the glue is prone to loosening and leakage after pouring, which reduces the stability and service life of the oil-water separator. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of the utility model is to provide a cover structure of an oil-water separator in view of the above-mentioned technical problems, so as to improve the assembly progress of the heating pipe and prevent the glue from loosening and leaking after pouring.

[0005] In view of this, the utility model provides a cover structure of an oil-water separator, comprising:

[0006] A cover body, wherein a connecting portion is provided on the cover body, and a mounting groove is provided in the connecting portion;

[0007] Also includes:

[0008] A mounting portion, the mounting portion is arranged in the cover body and located in the lower middle of the mounting groove, and a positioning hole is arranged on the mounting portion;

[0009] A glue hole, the glue hole is arranged at the bottom of the mounting groove, the glue hole is connected with the positioning hole, and a barb portion is arranged in the glue hole;

[0010] A heating tube, wherein the heating tube is arranged in the cover body;

[0011] The top of the heating tube can extend into the mounting groove through the positioning hole and the glue hole, and a limiting platform is provided between the positioning hole and the glue hole to limit the assembly position of the heating tube.

[0012] In the present technical scheme, when the oil-water separator is produced and assembled, the top of the heating tube is inserted into the positioning hole and moved into the positioning hole, and the top of the heating tube passes through the positioning hole and the glue hole to extend into the installation groove. Due to the presence of the limit platform, the heating tube is blocked and stops moving after moving to the limit platform. The setting of the limit platform effectively unifies the assembly position of the heating tube, thereby improving the assembly accuracy of the heating tube. After the heating tube is assembled, glue is poured into the installation groove. After the glue enters the installation groove, it moves into the glue hole and finally hardens. After the glue hardens, the glue hole is sealed and the heating tube is fixed. At the same time, the barb part can make the glue form a barb structure after the glue hardens, thereby preventing the glue from loosening, improving the stability of the glue after hardening, and the glue is not easy to loosen, which also improves the sealing effect at the glue hole and prevents leakage at the glue hole.

[0013] In the above technical solution, further, the diameter of the positioning hole is larger than the diameter of the glue hole, and the limiting platform is a platform formed by the diameter difference between the positioning hole and the glue hole.

[0014] In the above technical solution, further, the glue hole also includes:

[0015] A first hole, the first hole is arranged at the bottom of the mounting groove;

[0016] a second hole, the second hole being disposed at the bottom of the first hole;

[0017] The diameter of the first hole is smaller than that of the second hole, the diameter of the second hole is smaller than that of the positioning hole, the first hole is connected to the second hole, the second hole is connected to the positioning hole, and the barb portion is formed by the second hole.

[0018] In the above technical solution, further, the mounting portion protrudes downward from the inner top surface of the cover body, and the positioning hole extends from the bottom surface of the mounting portion to the glue hole and is connected to the glue hole.

[0019] In the above technical solution, further, the heating tube is a U-shaped heating tube, and two positioning holes and glue holes are provided at the connection ends corresponding to the top of the heating tube.

[0020] The beneficial effects of the utility model are:

[0021] 1. The installation position of the heating tube is effectively unified by setting the limit table, thereby improving the assembly accuracy of the heating tube;

[0022] 2. The setting of the hook part of the glue hole can effectively prevent the glue from loosening after hardening, improve the stability of the glue after hardening, and the glue is not easy to loosen, which also improves the sealing effect of the glue hole and prevents leakage at the glue hole;

[0023] 3. The structure of the positioning holes and glue holes is simple and reasonable, which is convenient for processing and production, and ensures production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Oil-water separator

[0035] The present embodiment proposes an oil-water separator in the prior art, which is usually composed of a water inlet, a separation chamber, an oil collection tank, an oil drain port, a water drain port and other components, and also has a cover structure, on which a series of electronic components such as a heating tube 8 and a temperature sensor are installed. The heating tube 8 is fixed to the cover structure by glue. The glue generally adopts electronic packaging glue, i.e., epoxy resin potting glue. The cover structure includes a cover body 1, on which a connecting portion 2 is provided, and a mounting groove 3 is provided in the connecting portion 2.

[0036] Positioning holes and mounting parts

[0037] The mounting portion 4 is arranged in the cover body 1 and is located in the lower middle of the mounting groove 3. A positioning hole 5 is arranged on the mounting portion 4. The top of the heating tube 8 can pass through the positioning hole 5 and extend into the mounting groove 3. A limiting platform 9 is arranged at the positioning hole 5 to limit the assembly position of the heating tube 8. The mounting portion 4 protrudes downward from the inner top surface of the cover body 1.

[0038] During production and assembly of the oil-water separator, the top of the heating tube 8 is inserted into the positioning hole 5 and moved into the positioning hole 5. The top of the heating tube 8 passes through the positioning hole 5 and extends into the mounting groove 3. Due to the presence of the limit platform 9, the heating tube 8 is blocked and stops moving after moving to the limit platform 9. The setting of the limit platform 9 effectively unifies the assembly position of the heating tube 8, thereby improving the assembly accuracy of the heating tube 8.

[0039] Glue hole

[0040] The glue hole 6 is arranged at the bottom of the installation groove 3, the glue hole 6 is connected with the positioning hole 5, and a barb 7 is arranged in the glue hole 6; the top of the heating tube 8 can pass through the positioning hole 5 and the glue hole 6 to extend into the installation groove 3, and a limiting platform 9 is arranged between the positioning hole 5 and the glue hole 6 to limit the assembly position of the heating tube 8. The diameter of the positioning hole 5 is larger than the diameter of the glue hole 6, and the limiting platform 9 is a platform formed by the diameter difference between the positioning hole 5 and the glue hole 6.

[0041] The glue hole 6 also includes: a first hole 60, which is arranged at the bottom of the mounting groove 3; a second hole 61, which is arranged at the bottom of the first hole 60; the diameter of the first hole 60 is smaller than the diameter of the second hole 61, and the diameter of the second hole 61 is smaller than the diameter of the positioning hole 5, the first hole 60 is connected with the second hole 61, and the second hole 61 is connected with the positioning hole 5, the barb portion 7 is composed of the second hole 61, and the positioning hole 5 extends from the bottom surface of the mounting portion 4 to the glue hole 6 and is connected with the glue hole 6, the heating tube 8 is a U-shaped heating tube 8, and the positioning hole 5 and the glue hole 6 are provided with two connecting ends corresponding to the top of the heating tube 8.

[0042] During production and assembly of the oil-water separator, the top of the heating tube 8 is inserted into the positioning hole 5 and moved into the positioning hole 5. The top of the heating tube 8 passes through the positioning hole 5 and the glue hole 6 and extends into the mounting groove 3. Due to the presence of the limit platform 9, the heating tube 8 is blocked and stops moving after moving to the limit platform 9. The setting of the limit platform 9 effectively unifies the assembly position of the heating tube 8, thereby improving the assembly accuracy of the heating tube 8. After the heating tube 8 is assembled, glue is poured into the mounting groove 3. After the glue enters the mounting groove 3, it moves into the glue hole 6 and finally hardens. After the glue hardens, the glue hole 6 is sealed and the heating tube 8 is fixed. At the same time, since the diameter of the second hole 61 is larger than the diameter of the first hole 60, the barb portion 7 formed by the second hole 61 can form a barb structure in the second hole 61 after the glue hardens, thereby preventing the glue from loosening and improving the stability of the glue after hardening. The glue is not easy to loosen, which also improves the sealing effect at the glue hole 6 and prevents leakage at the glue hole 6.

[0043] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
