Description

Technical Field

[0001] This utility model relates to the field of brake valve technology, specifically to a brake valve connector with built-in filtering function. Background Technology

[0002] When connecting the brake lines of a car, nylon quick-connect fittings are used. Because the brake valve has high requirements for the cleanliness of the lines, the input pollution of the air source varies. This includes air compressors, dryers, air tanks, and resin lines. Each component will affect the brake valve. In order to prevent impurities from entering the valve body and ensure that the brake valve can work normally, effective filtration measures are added to the air inlet to prevent large impurities from entering the valve body and damaging its braking performance.

[0003] The existing brake valve connectors still have some problems in use:

[0004] First, most existing integrated filter connectors use fixed single-layer filter screens, which have poor filtration effect and are troublesome to disassemble and clean, thus reducing the filtration effect and the practicality of the connector structure.

[0005] Secondly, existing integrated filter connectors lack a structure for positioning the filter components, which can easily lead to the filter components becoming loose during use. The movement of the filter components can also affect the filtration effect. Utility Model Content

[0006] In order to solve the problems of poor filtration effect and impracticality of existing connectors and easy loosening of filter components, the purpose of this utility model is to provide a brake valve connector with built-in filtration function.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a brake valve connector with built-in filtering function, comprising a connector body, wherein a filter assembly is provided inside the connector body, and a positioning assembly for use with the filter assembly is provided on one side of the connector body. The filter assembly includes symmetrically distributed mounting rods, the mounting rods being slidably engaged inside the connector body, and mounting shells being fixedly sleeved at equal intervals on the outer surface of the mounting rods. A filter screen is movably engaged inside the mounting shell, and a clamping bolt is connected to one side of the filter screen and the inner cavity of the mounting shell in a common annular array threaded connection.

[0008] Preferably, the positioning component includes a clamping plate, which is movably engaged with one side of the connector body. A slot for cooperating with the clamping plate is provided on one side of the connector body. The clamping plate is movably engaged with the slot and with one side of the mounting rod. A positioning bolt is threaded parallel to one side of the clamping plate and one side of the connector body.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This application improves the filtration effect by setting a detachable filter component and using a multi-layer filter screen design. The detachable design makes it convenient to disassemble and clean the filter screen, thereby improving the filtration effect of the connector and the practicality of the structure.

[0011] 2. This application uses a positioning component to facilitate the positioning and fixing of the filter structure in the connector, preventing the filter component from becoming loose or shifting during use, thereby ensuring the filtration effect of the connector.

[0018] 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.

[0019] Example: Figure 1-4As shown, this utility model provides a brake valve connector with built-in filtering function, including a connector body 1. The connector body 1 is provided with a filter component 2 inside. The filter component 2 facilitates the improvement of the filtering effect of the connector structure. A positioning component 3 is provided on one side of the connector body 1 to cooperate with the filter component 2. The positioning component 3 facilitates the positioning of the filter component 2 and prevents the filter component 2 from moving during use. There are two sets of positioning components 3, and the two sets of positioning components 3 are distributed in a mirror image, so as to achieve better positioning effect.

[0020] The filter assembly 2 includes symmetrically distributed mounting rods 26, which are slidably engaged inside the connector body 1. The mounting rods 26 have a T-shaped cross-section. The symmetrical design and T-shaped cross-section facilitate the quick installation and disassembly of the filter assembly 2. At the same time, the T-shaped structure prevents the mounting rods 26 from falling out of the connector body 1, ensuring the stable fixation of the filter assembly 2. The outer surface of the mounting rods 26 is fixedly fitted with mounting shells 21 at equal intervals. The interior of the mounting shells 21 is movably engaged with a filter screen 24. The filter screen 24 is a metal mesh. The metal filter screen 24 has strong corrosion resistance and a long service life. The movable engagement design facilitates individual disassembly for cleaning or replacement.

[0021] One side of the filter screen 24 is connected to the inner cavity of the mounting shell 21 by a ring-shaped threaded connection of clamping bolts 25. The clamping bolts 25 apply pressure evenly to ensure the seal between the filter screen 24 and the mounting shell 21. The filter screen 24 has a first mounting hole 23 in a ring-shaped array on one side, and the inner wall of the mounting shell 21 has a second mounting hole 22 in a ring-shaped array. The clamping bolts 25 are threadedly connected to the first mounting hole 23 and the second mounting hole 22. The precise alignment of the first mounting hole 23 and the second mounting hole 22 ensures the positioning accuracy of the clamping bolts 25 during installation, preventing the filter screen 24 from tilting or loosening. Multiple filtration improves the filtration effect, and the detachable design improves the convenience of cleaning the filter screen 24.

[0022] The positioning component 3 includes a locking plate 33, which is movably engaged with one side of the connector body 1. One side of the connector body 1 has a slot 35 for cooperating with the locking plate 33. The locking plate 33 and the slot 35 are movably engaged. The engagement between the slot 35 and the locking plate 33 can limit the axial displacement of the filter assembly 2 and ensure the stability of the filter assembly 2. The locking plate 33 is movably engaged with one side of the mounting rod 26. The engagement between the locking plate 33 and the mounting rod 26 further fixes the position of the filter assembly 2.

[0023] One side of the clamping plate 33 and one side of the connector body 1 are connected with a positioning bolt 31 in parallel thread. One side of the clamping plate 33 is provided with a first threaded groove 32 for use with the positioning bolt 31. The inner wall of the groove 35 is provided with a second threaded groove 34 for use with the positioning bolt 31. The positioning bolt 31 is threadedly connected with the corresponding first threaded groove 32 and second threaded groove 34. The parallel design of the first threaded groove 32 and the second threaded groove 34 allows the positioning bolt 31 to fix the clamping plate 33 and the connector body 1 at the same time, enhancing the stability and impact resistance of the overall structure, thereby ensuring the filtration effect.

[0024] Working principle: First, the filter assembly 2 is installed inside the connector body 1. The filter assembly 2 is positioned by the positioning assembly 3. The clamping plate 33 is movably clamped in the clamping groove 35 of the connector body 1 and simultaneously clamped with the T-shaped end of the mounting rod 26, restricting the axial displacement of the mounting rod 26.

[0025] The two sets of mirror-distributed positioning components 3 are further fixed by positioning bolts 31 connected by parallel threads. The positioning bolts 31 are simultaneously screwed into the first threaded groove 32 of the clamping plate 33 and the second threaded groove 34 of the clamping groove 35, locking the clamping plate 33 to the connector body 1, ensuring that the filter component 2 remains stable under vibration.

[0026] Then, the connector body 1 is installed on the brake valve. Compressed air enters the internal channel through the inlet of the connector body 1. The compressed air first contacts the filter component 2. The mounting shell 21 forms a multi-stage filtration structure. The compressed air passes through the metal filter screen 24 in each mounting shell 21 in sequence. The metal filter screen 24 intercepts impurity particles in the fluid for multiple filtrations.

[0027] The clamping bolts 25 of the annular array tightly fix the filter screen 24 to the mounting shell 21 through the first mounting hole 23 and the second mounting hole 22, ensuring that there is no leakage during the filtration process.

[0028] When the filter screen 24 needs to be cleaned or replaced, first loosen the positioning bolt 31, pull the retaining plate 33 out of the retaining groove 35, and release the lock on the mounting rod 26.

[0029] Then, the mounting rod 26 is slid out along the axial direction of the connector body 1, and the filter screen 24 can be removed separately by separating the clamping bolts 25 on the mounting shell 21, simplifying the maintenance process.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
