Description

Technical Field

[0001] This utility model relates to a quick-release assembly for toilet seats, and more particularly to a quick-release connecting pipe assembly for toilet seats. Background Technology

[0002] There are two main types of quick-release toilet seat structures. One type has a receiving cavity at the rear of the seat, with two locking mechanisms installed on the left and right sides of the receiving cavity at the rear of the seat, respectively. The other type has the two locking mechanisms directly installed on a separate connecting tube, which is then connected to the seat. The connecting tube integrates the two locking mechanisms beforehand, resulting in a neat overall structure and easy maintenance. However, the positioning method for the locking mechanisms within the connecting tube involves inserting locating pins between the connecting tube and the locking mechanisms. This requires locating pins for each locking mechanism, increasing the number of parts and steps involved in assembly, making assembly inconvenient. Furthermore, the locating pins need to be removed beforehand for subsequent assembly with the seat, which is also inconvenient. Utility Model Content

[0003] This utility model provides a quick-release connecting pipe assembly for toilet seat panels, which is convenient and quick to assemble and install. The technical solution adopted by this utility model to solve its technical problem is:

[0004] The toilet seat quick-release connecting tube assembly includes a connecting tube and two locking mechanisms. The two locking mechanisms are symmetrically inserted into the connecting tube and engage with it circumferentially. Each locking mechanism includes a push rod, a fixed shaft, a damper, and a locking spring. The damper is located at the outer end of the fixed shaft and is inserted into it. The push rod is located at the inner end of the fixed shaft and is axially inserted into it. The locking spring is tensioned between the push rod and the fixed shaft. When the locking mechanism is inserted into the connecting tube and reaches the working position, the shaft of the damper protrudes outside the connecting tube. When the locking mechanism is inserted into the connecting tube and reaches the working position, the push rod reaches its limit position in the inner direction. The fixed shaft is provided with a first elastic post, and the connecting tube is provided with a positioning hole. When the locking mechanism reaches the working position, the first elastic post springs into the positioning hole. When the first elastic post is pressed away from the positioning hole and pushes the damper inward, the damper and the fixed shaft compress the locking spring and move inward until the shaft of the damper retracts into the connecting tube.

[0005] In a preferred embodiment: the fixed shaft is provided with a first elastic arm, the end of the first elastic arm is provided with a first elastic post, and the fixed shaft is provided with a clearance groove corresponding to the first elastic arm.

[0006] In a preferred embodiment: the positioning hole is axially aligned with the support hole of the connecting pipe into which the support support is inserted.

[0007] In a preferred embodiment: the positioning hole is located outside the support hole, and when the first elastic post engages the side of the support hole facing the positioning hole, the length of the damper's shaft extending out of the connecting pipe is 2-6 mm.

[0008] In a preferred embodiment: a second elastic post is provided on the fixed shaft, and a locking hole is provided on the outer shell of the damper corresponding to the second elastic post.

[0009] In a preferred embodiment: the fixed shaft is provided with a second elastic arm, and the end of the second elastic arm is provided with a second elastic post, and the connecting tube presses the second elastic post into the locking hole.

[0010] In a preferred embodiment: during the insertion of the locking mechanism into the connecting tube, the second elastic post first enters the locking hole, and then the first elastic post springs into the positioning hole.

[0011] In a preferred embodiment: the first elastic arm and the second elastic arm are located on the upper and lower sides of the fixed shaft, respectively.

[0012] Compared with the prior art, this technical solution has the following advantages:

[0013] 1. During assembly, the quick-release connecting tube assembly features a built-in first elastic post on the fixed shaft. Once the connecting tube is in place, the first elastic post automatically springs into the positioning hole, thus positioning the locking mechanism. When assembling the quick-release connecting tube assembly with the cover plate, the push rod reaches its limit position in the inward direction, preventing further inward movement. Pressing down and disengaging the first elastic post from the positioning hole allows the damper and fixed shaft to be pushed axially inward until the damper's shaft retracts into the connecting tube, aligning with the cover plate. Releasing the damper then allows the locking spring to push the damper and fixed shaft outward. The first elastic post springs back into the positioning hole, while the damper's shaft extends out of the connecting tube and inserts into the cover plate. In summary, the locking mechanism is assembled and positioned using the first elastic post on the fixed shaft and the positioning hole in the connecting tube. Combined with the push rod reaching its limit position in the inward direction when in the working position, the assembly and installation of the quick-release connecting tube assembly are significantly more convenient and faster.

[0014] 2. A first elastic arm is set on the fixed shaft, which has its own elastic function and a simple structure.

[0015] 3. The fixed shaft is equipped with a second elastic column that mates with the locking hole on the damper housing, which can limit the damper to the fixed shaft, making the structure more stable. Attached Figure Description

[0027] Please refer to Figures 1 to 8The toilet seat quick-release connecting pipe assembly includes a connecting pipe 10 and two locking mechanisms 20. The two locking mechanisms 20 are inserted into the connecting pipe 10 in a mirror-symmetrical manner and are engaged with the connecting pipe circumferentially. Taking the connecting pipe as a reference, the center of the connecting pipe is considered the inner side, and the two ends of the connecting pipe are considered the outer side. The locking mechanism 20 includes a push rod 22, a fixed shaft 24, a damper 26, and a locking spring 28. The damper 26 is located at the outer end of the fixed shaft 24 and is inserted into the fixed shaft. The push rod 22 is located at the inner end of the fixed shaft 24 and is axially movable into the fixed shaft. That is, the push rod 22 and the fixed shaft 24 can move axially relative to each other. The locking spring 28 is tensioned between the push rod 22 and the fixed shaft 24. The rotating shaft 262 of the damper 26 is exposed outside the connecting tube 10 when the locking mechanism 20 is inserted into the connecting tube 10 and reaches the working position. That is, when the locking mechanism 20 is gradually inserted into the connecting tube 10 until the outer shell 264 of the damper 26 is completely inside the connecting tube 10 but the rotating shaft 262 is still outside the connecting tube 10, the assembly is complete, the locking mechanism 20 is in the working position, and the rotating shaft 262 can be inserted into the cover plate 30. The push rod 22 reaches its limit position in the inward direction when the locking mechanism 20 is inserted into the connecting tube 10 and reaches the working position, that is, the push rod 22 can no longer move inward. This can be because the connecting tube 10 blocks the push rod, or the button 40 that operates the push rod 22 to move outward blocks the push rod. For specific structure, please refer to the existing structure. The fixed shaft 24 is provided with a first elastic post 242, and the connecting pipe 10 is provided with a positioning hole 12. When the locking mechanism 20 reaches the working position, the first elastic post 242 springs into the positioning hole 12, so that the fixed shaft and push rod 22 can no longer move inward. When the first elastic post 242 is pressed away from the positioning hole 12 and pushes the damper 26 inward, the damper 26 and the fixed shaft 24 can compress the locking spring 28 and move inward until the rotating shaft 262 of the damper retracts into the connecting pipe 10, so that the connecting pipe can be installed into the cover plate 30.

[0028] Specifically, when assembling the quick-release connecting pipe assembly for the toilet seat, two locking mechanisms 20 are respectively inserted into the connecting pipe 10 from both sides (e.g., Figure 4 As shown), when the first elastic post 242 moves inward to the positioning hole 12, the first elastic post 242 springs into the positioning hole 12 (as shown). Figure 8 As shown), at this time, the locking mechanism 20 is in the working position, and the inner end of the push rod 22 is also blocked by the button 40, so the push rod cannot move further inward, while the pivot 262 of the damper 26 is just outside the connecting pipe 10. When it is necessary to install the toilet seat quick-release connecting pipe assembly onto the seat 30, press the first elastic post 242 to make it leave the positioning hole 12, and at the same time push the damper 26 inward (as shown). Figure 6As shown), the damper 26 and the fixed shaft 24 compress the locking spring 28 and continue to move inward. When the damper 26 is fully inserted into the connecting tube 10, the connecting tube 10 is placed into the cover plate 30. At this time, the external force is removed, and the locking spring 28 can push the damper 26 and the fixed shaft 24 outward, so that the damper shaft 262 is inserted into the cover plate, and the first elastic post 242 springs back into the positioning hole 12 (as shown). Figure 8 (As shown).

[0029] Preferably, the fixed shaft 24 is provided with a first elastic arm 244, and the end of the first elastic arm 244 is provided with a first elastic post 242. The fixed shaft 24 is provided with a relief groove corresponding to the first elastic arm. In this way, the first elastic arm enables the first elastic post to have a bouncing function, and the connecting tube 10 can force the first elastic arm 244 to retract into the relief groove. When the first elastic post 242 is aligned with the positioning hole 12, it can automatically pop out to achieve positioning.

[0030] Preferably, the positioning hole 12 is axially aligned with the support hole 14 of the connecting pipe 10 for inserting the support column. In this embodiment, the positioning hole 12 is located outside the support hole 14 and the two are close together. Therefore, during installation, when the first elastic post 242 is pressed away from the positioning hole 12 and the damper 26 is pushed inward, the first elastic post 242 moves to the support hole 14 and then pops out into the support hole 14. When the connecting pipe 10 is placed into the cover plate 30 and the external force is removed, the locking spring 28 automatically pushes the damper 26 and the fixed shaft 24 outward, and the first elastic post 242 locks the side of the support hole 14 facing the positioning hole 12 (e.g., Figure 7 As shown in the diagram, at this point, the damper's rotating shaft 262 extends 2-6 mm, preferably 5 mm, from the connecting pipe 10, completing the pre-installation. Afterward, simply pressing the first elastic post 242 away from the support hole 14 will cause the locking spring 28 to continue pushing the damper 26 and the fixed shaft 24 outward until the first elastic post 242 enters the positioning hole 12 (as shown in the diagram). Figure 8 (As shown).

[0031] Preferably, the fixed shaft 24 is provided with a second elastic post 246, and the outer shell 264 of the damper 26 is provided with a locking hole 266 corresponding to the second elastic post. Thus, during assembly, the second elastic post 246 can be inserted into the locking hole 266 under the squeezing action of the connecting pipe 10, so that the damper 26 and the fixed shaft 24 are axially engaged.

[0032] Preferably, the fixed shaft 24 is provided with a second elastic arm 248, and the end of the second elastic arm 248 is provided with a second elastic post 246, and the connecting tube 10 presses the second elastic post 246 into the locking hole.

[0033] Preferably, during the insertion of the locking mechanism 20 into the connecting tube 10, the second elastic post 246 first enters the locking hole 266, and then the first elastic post 242 springs into the positioning hole 12.

[0034] Preferably, the first elastic arm 244 and the second elastic arm 248 are located on the upper and lower sides of the fixed shaft 24, respectively.

[0035] Please refer to Figure 9 and Figure 10 The structural deformation diagram of the toilet seat quick-release connecting pipe assembly shows that the positioning hole 12 is set inside the support hole 14. In this way, during assembly, the first elastic column 242 first passes through the support hole 14 and then reaches the positioning hole 12. During installation, the first elastic column 242 is pressed inward to push the damper 26. The first elastic column 242 retracts into the clearance groove under the restriction of the connecting pipe 10. After the seat is installed, the external force is removed, and the rotating shaft 262 of the damper 26 is directly inserted into the seat 30. The first elastic column 242 is re-locked into the positioning hole 12.

[0036] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
