Description

Technical Field

[0001] The utility model relates to the technical field of sanitary ware accessories, in particular to a cylindrical damper for a toilet lid. Background Technique

[0002] In traditional toilets, the upper cover and the seat ring of the toilet are both hinged to the toilet body through hinges. After people use it, if they do not gently put down the toilet lid or the toilet seat ring by hand, the toilet lid or the toilet seat ring will collide with the toilet body, generating a lot of noise and also causing damage to the toilet seat ring or the toilet lid. For this reason, some manufacturers have designed toilet lids with damping mechanisms. The existing damping mechanisms need to push the blades through the damping oil pressure to realize the closing and opening of the oil cavity. When such damping devices are applied to the toilet seat cover, the installation is complex, the occupied space is large, and at the same time, the damping force generated is small. Therefore, a cylindrical damper for a toilet lid is proposed now. Content of the Utility Model

[0003] The purpose of the utility model is to provide a cylindrical damper for a toilet lid to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A cylindrical damper for a toilet lid, comprising: a bolt, a small sealing ring, an O-ring, a rotating head, a large sealing ring, a linkage block, a square washer, a shaft and a housing. One end of the shaft is installed at the bottom of the inner wall of the housing. The square washer is installed on the outer wall of the linkage block. The linkage block is sleeved on the outer wall of the shaft. The rotating head is arranged above the linkage block, and the large sealing ring is sleeved on the outer wall of the rotating head and placed inside the housing. The O-ring is installed between the rotating head and the housing, and the small sealing ring is sleeved on the outer wall of the bolt and connected to the rotating head through the bolt. The rotating head is used to transmit external forces. Among them, a thread groove is opened in the middle of the outer wall of the bolt. A first through hole is opened in the rotating head, and a step is formed at the first through hole. The small sealing ring is placed on the step. The bolt is threadedly connected to the first through hole through the thread groove. The inner wall of the first through hole of the rotating head is in interference fit with the grease at the top of the shaft to seal the grease. The small sealing ring on the step and the inner wall of the rotating head and the bolt are in interference fit to realize the grease sealing at the top of the shaft. The bolt is used to limit the movement of the small sealing ring.

[0006] Preferably, a central notch and two first threaded surfaces are opened at the bottom of the rotating head. A first gap is opened in the inner wall of the rotating head for the flow of grease. A groove is opened at the bottom of the rotating head, and the groove and the first threaded surface form two first retaining edges. An annular notch is opened on the outer wall of the rotating head, and the large sealing ring is installed in the annular notch to form a peripheral oil seal with the inside of the housing.

[0007] Preferably, two second threaded surfaces are provided on the top of the linkage block and are in clearance contact with the first threaded surface. Two grooves are formed on the top of the linkage block, and together with the second threaded surfaces, they form a second stop edge that is adapted to the first stop edge. The two second threaded surfaces on the linkage block are in contact with the spiral surface of the rotating head. When the rotating head rotates counterclockwise, the linkage block is urged to move downward along the axis. When the rotating head rotates clockwise, the two fourth threaded surfaces on the axis are in contact with the two third threaded surfaces at the bottom of the linkage block, urging the linkage block to move upward along the axis. At the same time, the first stop edge contacts the second stop edge on the linkage block when rotating clockwise to a certain angle, and at this time, it cannot be rotated further.

[0008] Preferably, a bottom groove is formed on the outer wall of the linkage block, and the square washer is installed in the bottom groove. Two horizontal surfaces are provided on the outer wall of the linkage block. Second gaps and third gaps are respectively formed on the horizontal surfaces and curved surfaces of the linkage block. Two third threaded surfaces are provided at the bottom of the linkage block, and a groove is formed at the bottom to form a first bottom stop edge with the third threaded surface. When the linkage block moves upward, it adheres to the lower stop edge, and a large gap is generated between the linkage block and the square washer to facilitate the flow of grease. When the linkage block moves downward, the square washer adheres to the upper stop edge, and the flow channel here is closed.

[0009] Preferably, a central groove surface is formed at the top of the axis, and through the central groove surface, it is installed in the central notch of the rotating head to rotate synchronously with the rotating head. A round hole is formed on the linkage block, and the linkage block is sleeved on the outer wall of the axis through the round hole. A round table is fixedly connected to the bottom of the inner wall of the housing. A central hole is formed at the bottom of the axis and is sleeved on the outer wall of the round table to maintain concentricity during rotation. A first oil hole and a second oil hole are respectively formed at the top and outer wall of the axis and are interconnected, forming a grease flow channel from bottom to top. Two third stop edges are fixedly connected to the outer wall of the axis, and a fourth threaded surface is formed on one side of the third stop edge. The fourth threaded surface is in contact with the third threaded surface. When rotating counterclockwise, grease enters from the second oil hole and flows out from the first oil hole. When the third stop edge rotates counterclockwise to contact the first bottom stop edge of the linkage block, the rotation ends and returns to the initial state.

[0010] Preferably, two concave planes are provided on the outer wall of the housing for installing a fixed cylindrical damper. A curled edge that turns inward is provided at the top of the inner wall of the housing. The two sides of the O-ring are respectively in contact with the rotating head and the curled edge. The entire structure is contained and operated inside through the top curled edge. The O-ring is sleeved on the rotating head, one flat surface is in contact with the upper flat surface of the rotating head, and the other flat surface is in contact with the inner side of the top curled edge of the housing, restricting the up and down movement of the rotating head.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] By performing left - right limited - angle rotation damping, when the rotating head is turned, the internal linkage block moves up and down along the axis, and cooperates with the square washer to make the grease flow up and down, thereby generating different damping force effects in the left - right direction. This type of cylindrical damper not only has a simple installation and occupies a small space, but also can generate a large damping force, with a wide range of applications, and is more in line with the market demand.

The linkage block 6 is sleeved on the outer wall of the shaft 8. The rotating head 4 is arranged above the linkage block 6. The large sealing ring 5 is sleeved on the outer wall of the rotating head 4 and placed inside the housing 9. The O-ring 3 is installed between the rotating head 4 and the housing 9. The small sealing ring 2 is sleeved on the outer wall of the bolt 1 and is connected to the rotating head 4 through the bolt 1. The rotating head 4 is used to transmit external force. Among them, a thread groove 11 is formed in the middle of the outer wall of the bolt 1. A first through hole 46 is formed in the rotating head 4. A step 47 is formed at the first through hole 46. The small sealing ring 2 is placed on the step 47. The bolt 1 is threadedly connected to the first through hole 46 through the thread groove 11. The inner wall of the first through hole 46 of the rotating head 4 is in interference fit with the top of the shaft 8 for grease sealing. The grease sealing is mainly achieved by the small sealing ring, and the bolt restricts the movement of the sealing ring.

[0029] A central notch 42 and two first threaded surfaces 41 are formed at the bottom of the rotating head 4. A first gap 43 is formed in the inner wall of the rotating head 4 for grease flow.

When the rotating head 4 rotates counterclockwise, the linkage block 6 is urged to move downward along the shaft 8. The two third threaded surfaces 62 at the bottom of the linkage block 6 are in contact with the two fourth threaded surfaces 84 on the shaft 8. When the rotating head 4 rotates clockwise, the linkage block 6 is urged to move upward along the shaft 8. At the same time, the first retaining edge 44 rotates clockwise to a certain angle and contacts the second retaining edge 611 on the linkage block 6.

[0032] A central notch surface 81 is provided at the top of the shaft 8, and it is installed in the central notch 42 of the rotating head 4 through the central notch surface 81 to rotate synchronously with the rotating head 4. A circular hole 69 is provided on the linkage block 6, and it is sleeved on the outer wall of the shaft 8 through the circular hole 69. A frustum 92 is fixedly connected to the bottom of the inner wall of the housing 9.

A first oil hole 82 and a second oil hole 83 are respectively provided on the top and the outer wall of the shaft 8 and are interconnected, thus forming a grease flow channel from bottom to top. Two third retaining edges 85 are fixedly connected to the outer wall of the shaft 8, and a fourth threaded surface 84 is provided on one side of the third retaining edge 85. The fourth threaded surface 84 contacts the third threaded surface 62. When rotating counterclockwise, the grease enters from the second oil hole 83 and flows out from the first oil hole 82. When the third retaining edge 85 rotates counterclockwise to contact the first bottom retaining edge 68 of the linkage block 6, the rotation ends and returns to the initial state.

[0033] Two concave planes 91 are provided on the outer wall of the housing 9 for installing the fixed cylindrical damper. A curled edge 93 that turns inward is provided at the top of the inner wall of the housing 9. Two sides of the O-ring 3 are respectively in contact with the rotating head 4 and the curled edge 93. The entire structure is contained and operated inside through the top curled edge 93. The O-ring is sleeved on the rotating head 4. One flat surface 31 contacts the upper flat surface 48 of the rotating head 4, and the other flat surface 31 contacts the inner side of the top curled edge 93 of the housing 9, restricting the up and down movement of the rotating head 4.

[0034] The working principle of the present utility model is as follows:

[0035] Combined with Figure 10 , from its initial position, the rotating head 4 rotates clockwise to the bottom and then rotates counterclockwise back to the initial position; First, when the rotating head 4 is subjected to a clockwise rotating force at the initial position, it will drive the shaft 8 to rotate clockwise. The fourth helical surface 84 at the bottom of the shaft 8 presses the third helical surface 62 at the bottom of the linkage block 6, causing the linkage block 6 to move upward along the shaft 8, squeezing the grease space in the upper part of the housing 9, and the grease begins to flow downward along the third gap 61 and the second gap 65 between the linkage block 6 and the housing 9, driving the bottom surface of the square washer 7 to adhere to the lower retaining edge 67 at the bottom of the linkage block 6. At this time, the grease flows from the gap between the linkage block 6 and the square washer 7 to the bottom of the housing 9 until the first retaining edge 44 on the rotating head 4 touches the second retaining edge 611 of the linkage block 6, and the clockwise rotation ends. The whole process squeezes the grease to flow from top to bottom, and the force value is small;

[0036] Secondly, when the rotating head 4 rotates clockwise to the end and starts to be subjected to a counterclockwise rotating force, the first helical surface 41 at the bottom of the rotating head 4 presses against the second helical surface 64 above the linkage block 6, causing the linkage block 6 to move downward along the shaft 8, squeezing the grease space at the lower part of the housing 9. The grease pushes the upper surface of the square washer 7 to adhere to the upper edge 66 of the linkage block 6. The grease flows in through the second oil hole 83 at the bottom of the shaft 8 and flows out through the first oil hole 82 at the top of the shaft 8, and enters the upper space of the housing 9 through the first gap 43 between the rotating head 4 and the shaft 8. The downward movement of the linkage block 6 gradually completely blocks the second oil hole 83 at the bottom of the shaft 8. At this time, the grease can only flow into the upper space of the housing through the fitting gap between the linkage block 6, the square washer 7 and the housing until the third edge 85 at the bottom of the shaft 8 touches the first bottom edge 68 at the bottom of the linkage block 6, and the counterclockwise rotation ends. During the whole process, the force value changes continuously and shows an overall increasing trend.

[0037] Therefore, when the rotating head 4 rotates clockwise, the linkage block 6 moves upward, and the grease flows from the upper space of the housing to the lower space. The gap is large, the fluidity is high, and the damping force generated is small; when the rotating head 4 rotates counterclockwise, the linkage block 6 moves downward, and the grease flows from the lower space of the housing to the upper space. The gap is small, the fluidity is weak, and the damping force generated is large.

[0038] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
