Specific embodiments

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Please refer to Figure 1 It is a schematic diagram of the structure of a preferred embodiment provided by the present invention for the connection structure of the oil filter; Figure 2 It is Figure 1 The enlarged schematic diagram of part A of the support structure shown; Figure 3 It is a schematic diagram of the structure of another preferred embodiment provided by the present invention for the connection structure of the oil filter; Figure 4 It is Figure 3 The enlarged schematic diagram of part B shown;

[0025] Figure 5 It is Figure 4 The enlarged schematic diagram of part C shown; Figure 6 It is a schematic diagram of the connection structure of the U-shaped support plate, thin rope and pendulum ball. The connection structure for the oil filter includes: It also includes a U-shaped support plate 1, four first connecting sleeves 2 that are parallel to each other in the same plane, and a shock-absorbing spring 3; Raised blocks 4 are fixedly connected to the inner sides of the two side plates of the U-shaped support plate 1, and the shape of the raised block 4 matches the shape of the groove on the filter element frame, and is used to clamp the filter element on the U-shaped support plate 1.

[0026] At the four corners inside the housing 5, a first connecting sleeve 2 is fixedly connected respectively to support the U-shaped support plate 1. At the four corners of the U-shaped support plate 1, a second connecting sleeve 6 is fixedly connected respectively. The U-shaped support plate 1 is supported by slidingly sleeving the second connecting sleeve 6 on the first connecting sleeve 2; when the four second connecting sleeves 6 are slidingly sleeved on the first connecting sleeve 2 one by one, the U-shaped support plate 1 can reciprocate along the axis of the first connecting sleeve 2; one end of the first connecting sleeve 2 is fixedly connected with a first baffle 7, and the other end of the connecting sleeve is fixedly connected with a second baffle 8; a second connecting sleeve 6 and a shock-absorbing spring 3 are slidingly sleeved on each first connecting sleeve 2, and the second connecting sleeve 6 and the shock-absorbing spring 3 are located between the first baffle 7 and the second baffle 8; and one end of the shock-absorbing spring 3 abuts against the first baffle 7, and the other end of the shock-absorbing spring 3 abuts against the second connecting sleeve 6. Therefore, when the U-shaped support plate 1 reciprocates along the axis of the first connecting sleeve 2 due to vibration, the shock-absorbing spring 3 absorbs energy, which can play a shock-absorbing role on the U-shaped support plate 1, and further play a shock-absorbing role on the filter element installed on the U-shaped support plate 1.

[0027] As another implementation scheme of the embodiment, it further includes a supporting screw 9, and the supporting screw 9 is fixedly connected inside the housing, so the housing supports the first connecting sleeve 2 through the supporting screw 9; the first connecting sleeve 2 is a threaded sleeve, and the first connecting sleeve 2 is threaded on the supporting screw 9. By rotating the first connecting sleeve 2, the first connecting sleeve 2 can move along the supporting screw 9 to adjust the position of the U-shaped support plate 1, that is, adjust the position of the filter element. After adjustment, since the supporting screw 9 and the threaded sleeve are locked by threads, the position of the threaded sleeve relative to the supporting screw 9 remains unchanged, and thus the position of the U-shaped support plate 1 remains unchanged. The first baffle 7 is in the shape of a knob, which is convenient for operating to rotate the first connecting sleeve 2.

[0028] As another implementation scheme of the embodiment, the raised block 4 is fixedly connected with a first rubber pad 10 along the inner sides of the two side plates of the U-shaped support plate 1; a second rubber pad 11 is fixedly connected to the middle plate of the U-shaped support plate 1. When the filter element is installed on the U-shaped support plate 1, both the first rubber pad 10 and the second rubber pad 11 are in contact with the filter element. When the U-shaped support plate 1 shakes, the first rubber pad 10 can buffer the vibration of the filter element in the shaking direction, and the second rubber pad 11 can buffer the vibration of the filter element in the direction perpendicular to the shaking direction.

[0029] As another implementation of the embodiment, a number of pendulum balls 12 of the same size are arrayed at the bottom of the U-shaped supporting plate 1. Each pendulum ball 12 is suspended from the bottom of the U-shaped supporting plate 1 by an equal-length thin string 13, and the distance between two adjacent pendulum balls 12 is less than the length of the thin string 13. When the U-shaped supporting plate 1 shakes, the pendulum balls 12 start to swing to absorb the energy of the U-shaped supporting plate 1, so as to reduce the shaking amplitude of the U-shaped supporting plate 1 and thus achieve the purpose of assisting in vibration damping. The pendulum balls 12 are of the same size, the thin strings 13 are of equal length, and the distance between adjacent pendulum balls 12 is greater than the length of the thin string 13, so the swinging amplitudes and frequencies of a number of pendulum balls 12 are the same, and they will not collide with each other during the swinging process.

[0030] As another implementation of the embodiment, a number of rolling grooves 14 are provided along the inner peripheral surface of the second connecting sleeve 6. A ball 15 is rotatably connected in each rolling groove 14, and the ball 15 is in rolling contact with the outer surface of the first connecting sleeve 2. By providing the ball 15, it is possible to avoid the situation of jamming when the second connecting sleeve 6 slides along the first connecting sleeve 2.

[0031] As another implementation of the embodiment, both the first baffle 7 and the second baffle 8 are fixedly connected to the first connecting sleeve 2 by bolts 16, and the first connecting sleeve 2 is fixedly connected to the U-shaped supporting plate 1 by bolts 16. Since the first connecting sleeve 2 and the second connecting sleeve 6 are prone to wear, the fixed connection by bolts 16 facilitates the independent replacement of the first connecting sleeve 2 or the second connecting sleeve 6.

[0032] As another implementation of the embodiment, a locking threaded sleeve 17 is coaxially and fixedly connected to the first connecting sleeve 2. The inner surface of the locking threaded sleeve 17 is provided with internal threads, and the outer surface of the locking threaded sleeve 17 is provided with external threads; the locking threaded sleeve 17 is threadedly sleeved on the supporting screw 9, and the supporting screw 9 is threadedly sleeved with the locking threaded sleeve 17 by being threadedly connected with the internal threads; and a locking nut 18 is threadedly sleeved on the locking threaded sleeve 17, and the locking nut 18 is threadedly sleeved with the locking threaded sleeve 17 through the external threads. First, the locking threaded sleeve 17 can increase the threaded locking force between the first connecting sleeve 2 and the supporting screw 9, so that the first connecting sleeve 2 and the supporting screw 9 are firmly locked, so as to improve the connection firmness between the U-shaped supporting plate 1 and the first connecting sleeve 2; second, after repeated use, the threaded retracting sleeve and the threaded contact surfaces of the first connecting sleeve 2 and the supporting screw 9 will be worn, and this wear will cause the threaded engagement degree between the first connecting sleeve 2 and the supporting screw 9 to decrease; at this time, the pressure between the locking threaded sleeve 17 and the supporting screw 9 can be increased by tightening the locking nut 18 to improve the engagement degree between the locking threaded sleeve 17 and the supporting screw 9, and then improve the threaded locking force between the locking threaded sleeve 17 and the supporting screw 9, thereby indirectly increasing the threaded locking force between the first connecting sleeve 2 and the supporting screw 9 to improve the stability of the fixed connection between the U-shaped supporting plate 1 and the housing 5.

[0033] The working principle of the connection structure for the oil filter provided by the present utility model is as follows:

[0034] When the U-shaped supporting plate 1 reciprocates axially along the first connecting sleeve 2 due to vibration, the shock-absorbing spring 3 absorbs energy, which can play a shock-absorbing role for the U-shaped supporting plate 1, and further realizes the shock-absorbing effect on the filter element installed on the U-shaped supporting plate 1.

[0035] Compared with the related art, the connection structure for the oil filter provided by the present utility model has the following beneficial effects:

[0036] The present utility model provides a connection structure for an oil filter. By providing a U-shaped supporting plate 1 to support the filter element, the filter element does not need to be in direct contact with the base; the U-shaped supporting plate 1 is slidably sleeved on the first connecting sleeve 2 through a second connecting sleeve 6, and through the buffering action of the shock-absorbing spring 3, the buffering of the U-shaped supporting plate 1 in the horizontal direction can be realized.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
