The present invention will be described in detail with reference to fig. 1 to 6 in conjunction with the embodiments.

Referring to fig. 1 to 2, a filter press 100 according to an embodiment of the present invention includes: connecting the base 10 and the filter press lid 20.

Specifically, as shown in FIG. 1, a filter cap 20 can be used to protect a filter cartridge and the attachment base 10 can be used to carry the filter cap 20. The connecting base 10 and the filter cap 20 may be threadably connected, e.g., the filter cap 20 may be rotated in a first direction (e.g., clockwise as viewed in fig. 3) relative to the connecting base 10 to effect threaded connection of the connecting base 10 to the filter cap 20; when it is desired to remove the filter cap 20, the filter cap 20 may be rotated relative to the attachment base 10 in a second direction (e.g., counterclockwise as viewed in fig. 3) opposite the first direction to disengage the attachment base 10 from the filter cap 20. In addition, the connecting base 10 can be matched with the transmission housing through a connecting mode such as a bolt.

To connecting seat and filter press lid threaded connection's structure, among the correlation technique, the pressure filter has the risk of the anti-pine of filter press lid under the complicated operating mode such as the pressure impact of inside is great, the vibration frequency is higher.

Therefore, in the embodiment of the present invention, as shown in fig. 1 to 3, the connection base 10 is provided with the locking portion 11, and the filter press cover 20 is provided with the locking fitting portion 21. As shown in fig. 6, in a state where the filter cap 20 is coupled to the coupling base 10 in place, that is, in a state where the filter cap 20 is rotated to be tightened in a first direction with respect to the coupling base 10, that is, in a state where the filter cap 20 is tightened to a target moment (determined according to actual circumstances), the locking portion 11 may be engaged with the locking engagement portion 21 to prevent the filter cap 20 from being rotated in a second direction. Therefore, the locking part 11 and the locking matching part 21 are matched to form a locking structure, and the filter press cover 20 is prevented from being loosened reversely under complex working conditions.

It should be noted that the relative positions of the locking portion 11 and the locking mating portion 21 along the circumferential direction of the filter cover 20 in the process of rotating the filter cover 20 in the first direction shown in fig. 2-5 and in the state of connecting the filter cover 20 with the connecting base 10 shown in fig. 6 are only used for illustrative purposes, and it is understood by those skilled in the art that the locking portion 11 and the locking mating portion 21 are in other relative positions after the filter cover 20 is connected with the connecting base 10 according to the description of the embodiment of the present invention.

According to the utility model discloses a pressure filter 100 cooperatees through locking cooperation portion 21 that sets up on 11 of the locking portion that sets up on the connecting seat 10 and the pressure filter lid 20, can prevent that pressure filter lid 20 antiport and pine from taking off after pressure filter lid 20 targets in place with connecting seat 10 threaded connection, reduces pressure filter 100 and leaks the risk, can satisfy the user demand and the security of complicated operating mode.

The embodiment of the present invention provides a flexible arrangement of the anti-loosening part 11 and the anti-loosening matching part 21 according to actual conditions. For example, the looseness prevention part 11 and the looseness prevention fitting part 21 may be a shaft hole fitting structure, a snap-fit structure, or the like.

In some embodiments, as shown in fig. 1-3, the anti-loose part 11 may be an anti-loose protrusion 12, and the anti-loose fitting part 21 may be a fitting protrusion 22. During the process of connecting the filter cover 20 to the connecting holder 10, that is, during the process of rotating the filter cover 20 from the initial position where the filter cover is covered on the connecting holder 10 to the tightening position in the first direction, the engaging protrusion 22 can rotate with the filter cover 20 in the first direction and move from one side to the other side of the anti-loosening protrusion 12. So that the locking protrusion 12 is located at one side of the fitting protrusion 22 in the second direction in a state where the filter cap 20 is coupled to the coupling seat 10 in place.

Referring to fig. 4 and 5, the distance between the locking protrusion 12 and the rotation axis of the filter cap 20 is L1, the distance between the fitting protrusion 22 and the rotation axis of the filter cap 20 is L2, and L1 < L2. After the connection seat 10 and the filter cap 20 are connected in place, the anti-loose protrusion 12 and the fitting protrusion 22 are at least partially not staggered in the radial direction of the filter cap 20, that is, have a certain interference amount, in other words, when the fitting protrusion 22 rotates to pass through the anti-loose protrusion 12, the fitting protrusion 22 and the anti-loose protrusion 12 are pressed to interfere with each other, and resistance is generated.

Thus, when the filter press 100 tends to loosen due to internal pressure shock or the like, even if the screwing torque is removed and the filter cover 20 is rotated in the second direction, when the fitting projection 22 contacts the loosening prevention projection 12, the generated reverse force prevents the filter cover 20 from continuing to rotate in the second direction, and plays a role in loosening prevention.

In some embodiments of the present invention, the anti-loosening projections 12 and the mating projections 22 are configured to: the moment of driving the mating protrusion 22 from one side to the other side of the anti-loosening protrusion 12 is greater than 1Nm. In other words, when the fitting projection 22 rotates past the anti-loosening projection 12, the fitting projection 22 presses and interferes with the anti-loosening projection 12, resistance is generated, and it is necessary to continuously increase the torque so that the fitting projection 22 passes over the anti-loosening projection 12, and the tightening torque of the fitting projection 22 passing over the anti-loosening projection 12 is greater than 1Nm. When the pressure filter 100 is tightened to the target moment, the rotation is stopped, and the installation of the pressure filter 100 is completed. On the contrary, when the filter press cover 20 is disassembled, the moment for enabling the matching convex part 22 to cross the anti-loosening convex part 12 along the second direction is also larger than 1Nm, so that the acting force caused by complex working conditions such as internal pressure cannot enable the matching convex part 22 to cross the anti-loosening convex part 12 along the second direction, and an effective anti-loosening effect is achieved.

According to some embodiments of the present invention, as shown in fig. 3-6, the side of the anti-loosening protrusion 12 may include a first guide slope 13, and the first guide slope 13 extends in the first direction toward the direction close to the rotation axis of the filter cover 20. In the process that the filter press cover 20 rotates along the first direction to be in threaded connection with the connecting seat 10, the first guide inclined surface 13 of the anti-loosening convex part 12 can be abutted against the matching convex part 22 to guide the matching convex part 22, so that the resistance of the matching convex part 22 to pass over the anti-loosening convex part 12 is reduced, and the filter press cover 20 is screwed more easily.

According to some embodiments of the present invention, as shown in fig. 3-6, the side of the mating protrusion 22 includes a first mating ramp 23, the first mating ramp 23 extending in a first direction toward the axis of rotation of the filter cover 20. In the process that the filter cover 20 rotates along the first direction to be in threaded connection with the connecting seat 10, the first matching inclined surface 23 of the matching convex part 22 can be abutted against the anti-loosening convex part 12 to play a guiding role, so that the resistance of the matching convex part 22 to cross the anti-loosening convex part 12 is reduced, and the filter cover 20 is screwed more easily.

Of course, the locking protrusion 12 and the mating protrusion 22 may also be provided with the first guiding inclined surface 13 and the first mating inclined surface 23 at the same time, so that the guiding effect is better.

According to some embodiments of the present invention, as shown in fig. 3-6, the side of the anti-loosening protrusion 12 may include a second guide slope 14, and the second guide slope 14 extends in the second direction toward the direction close to the rotation axis of the filter cover 20. In the process that the filter cover 20 rotates along the second direction to release the threaded connection with the connecting seat 10, the second guide inclined surface 14 of the anti-loosening convex part 12 can abut against the matching convex part 22 to guide the matching convex part 22, so that the resistance of the matching convex part 22 to pass over the anti-loosening convex part 12 is reduced, and the filter cover 20 is easier to disassemble.

According to some embodiments of the present invention, as shown in fig. 3-6, the side of the mating protrusion 22 includes a second mating ramp 24, the second mating ramp 24 extending in a second direction toward the direction of the axis of rotation of the filter lid 20. In the process that the filter cap 20 rotates along the second direction to release the threaded connection with the connecting seat 10, the second matching inclined surface 24 of the matching convex part 22 can be abutted against the anti-loosening convex part 12 to play a guiding role, so that the resistance of the matching convex part 22 crossing the anti-loosening convex part 12 is reduced, and the filter cap 20 is easier to disassemble.

Of course, the locking protrusion 12 and the mating protrusion 22 may also be provided with the second guiding inclined surface 14 and the second mating inclined surface 24 at the same time, so that the guiding effect is better.

In some embodiments, as shown in fig. 5 and 6, two sides of the anti-loosening protrusion 12 opposite to each other respectively include a first guide slope 13 and a second guide slope 14, and the distance between the first guide slope 13 and the second guide slope 14 increases outward in the radial direction of the filter cover 20. In other words, the width of the anti-loosening projections 12 in the first direction increases progressively radially outwardly of the filter cap 20.

In some embodiments, as shown in fig. 5 and 6, the two sides of the mating protrusion 22 facing away from each other include a first mating ramp 23 and a second mating ramp 24, respectively, and the spacing between the first mating ramp 23 and the second mating ramp 24 decreases in a radial direction of the filter press cover 20. In other words, the width of the fitting projection 22 in the first direction decreases outward in the radial direction of the filter cover 20.

According to some embodiments of the present invention, as shown in fig. 3 and 4, the plurality of mating protrusions 22 (including but not limited to the three shown in fig. 3) are provided, and the plurality of mating protrusions 22 are spaced apart along the circumference of the filter lid 20. At least one fitting protrusion 22 is located at the other side of the anti-loose protrusion 12 in a state where the filter press cover 20 is coupled to the coupling holder 10.

Due to the influence of the manufacturing and assembling processes, it cannot be guaranteed that the fitting protrusion 22 is located at the same position after each tightening, and by providing a plurality of fitting protrusions 22, it can be guaranteed that at least one fitting protrusion 22 can pass over the anti-loosening protrusion 12 in each tightening process, thereby achieving the anti-loosening effect. Moreover, in the embodiment in which the plurality of fitting protrusions 22 are rotated to the other side of the anti-loose protrusion 12, a multi-stage anti-loose effect can be achieved by the plurality of fitting protrusions 22, and the anti-loose effect is better.

In some embodiments of the present invention, as shown in fig. 1, the locking protrusion 12 is offset from the thread starting point 15 of the connection seat 10, and the fitting protrusion 22 is offset from the thread starting point 25 of the filter cap 20 in the circumferential direction of the filter cap 20. In other words, the locking protrusion 12 is at an angle to the thread starting point 15 of the connection seat 10, and the mating protrusion 22 is at an angle to the thread starting point 25 of the filter press cover 20. When the filter cap 20 is screwed down to the target torque at the above-described angle, it is ensured that the fitting projections 22 can pass over the locking projections 12, and in the embodiment where the fitting projections 22 are plural, it is ensured that at least one fitting projection 22 can pass over the locking projections 12, and the locking function is performed.

It should be noted that, in the state where the filter cap 20 and the connection base 10 are screwed down by the target torque, the positions of the locking protrusion 12 and the fitting protrusion 22 in the circumferential direction of the two can be determined, and further, the angle between the locking protrusion 12 and the thread starting point 15 of the connection base 10 and the angle between the fitting protrusion 22 and the thread starting point 25 of the filter cap 20 can be determined.

In some embodiments of the present invention, the engaging protrusion 22 passes through the locking protrusion 12 once in the first direction during the process of connecting the filter press cover 20 and the connecting seat 10. In the embodiment in which the fitting projection 22 is plural, each fitting projection 22 is allowed to pass over the loosening-preventing projection 12 only once in the first direction. Therefore, the locking effect is prevented from being influenced by serious abrasion caused by multiple times of friction between the matching convex part 22 and the locking convex part 12.

In some embodiments of the present invention, the locking portion 11 may be integrally formed on the connecting socket 10. For example, as shown in fig. 3, the locking portion 11 is a locking protrusion 12, and the locking protrusion 12 is integrally formed on the upper portion of the peripheral wall of the connection socket 10, so that the number of parts of the filter press 100 does not need to be increased, and only the structure of the connection socket 10 is improved, thereby saving the production cost and the design cost of the production mold.

In some embodiments of the present invention, the anti-loosening fitting 21 may be integrally formed on the filter cap 20. For example, as shown in fig. 3, the filter cap 20 includes a filter cap body and an annular filter cap rib, the filter cap rib is connected to the lower portion of the peripheral wall of the filter cap body, the anti-loose fitting portion 21 is a fitting projection 22 and is integrally formed on the outer peripheral surface of the filter cap rib, the number of parts of the filter 100 does not need to be increased, the filter cap 20 is improved only on the basis of the structure thereof, and the production cost and the production mold design cost are saved.

In some embodiments of the present invention, the connecting seat 10 may be made of PA6 or PA66, and the filter press cover 20 may be made of PA6 or PA 66.

According to another aspect of the present invention, a vehicle includes the filter press 100 of the above embodiment. Because according to the utility model discloses pressure filter 100 has above-mentioned profitable technological effect, consequently according to the utility model discloses the vehicle, the locking cooperation portion 21 that sets up on locking portion 11 that sets up on the connecting seat 10 through pressure filter 100 and the pressure filter lid 20 cooperatees, can prevent that pressure filter lid 20 antiport and pine from taking off after pressure filter lid 20 targets in place with connecting seat 10 threaded connection, reduces pressure filter 100 and leaks the risk, can satisfy the user demand and the security of complicated operating mode.
