[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1 to 4 As shown, this utility model can be implemented through the following embodiments: A tap that is easy to assemble and disassemble includes an installation tube 1 and a cone 2. An installation cavity 11 is provided inside the installation tube 1, and an installation groove is provided on the cone 2. A sliding groove 111 is provided inside the installation cavity 11. A positioning groove 13 is provided on the inner wall of the installation cavity 11. A push plate 3 is installed in the sliding groove 111. An installation part 21 is provided at the top of the cone 2. A locking post 211 is installed in the installation part 21. A spring 212 is installed between the locking post 211 and the installation part 21.

[0021] The cone 2 is installed in the mounting cavity 11 by setting the mounting part 21 and installing a locking post 211 and a spring 212. The locking post 211 engages with the positioning groove 13 to install the cone 2 in the mounting cavity 11. The spring 212 is used to push the locking block into the positioning groove 13 to prevent the locking block from disengaging from the positioning groove 13, ensuring a stable connection, and at the same time facilitating the release of the locking block from the positioning groove 13. The locking block is inserted into the mounting part 21 through a stepped structure, so that it will not shift when the tap rotates, thus improving the connection stability. The push plate 3 is slidably connected to the sliding groove 111 and is moved by the user to push the locking block away from the positioning groove 13, thereby releasing the connection between the cone 2 and the mounting tube 1, and facilitating the quick replacement of the damaged cone 2.

[0022] like Figures 1 to 3 As shown, the sliding groove 111 is connected to the pressure groove 12, and a pressure plate 31 is installed in the pressure groove 12. The pressure plate 31 is connected to the push plate 3. The connection between the pressure plate 31 and the push plate 3 allows the user to push the push plate 3 to move by pressing the pressure plate 31, thereby releasing the jamming between the cone 2 and the mounting tube 1. The pressure groove 12 is used to guide the movement of the pressure plate 31 and prevent the pressure plate 31 from shifting, which would cause uneven force at the connection between the push plate 3 and the pressure plate 31 and damage it.

[0023] like Figure 2 and Figure 3 As shown, the mounting part 21 is rectangular, and a gap 4 is left between the mounting part 21 and the mounting cavity 11. The rectangular mounting part 21 and the circular mounting tube 1 form a gap 4, which facilitates the insertion of the push plate 3, thereby pushing the locking block away from the positioning groove 13.

[0024] like Figure 2 As shown, the push plate 3 has a triangular tip 32 at its end, the locking post 211 has an inclined surface 211a, and the triangular tip 32 has a hardening layer 321. The triangular tip 32 is used to insert into the gap 4 and cooperate with the inclined surface 211a on the locking post 211 to push the locking post 211 out of the mounting groove; the hardening layer 321 is used to reduce wear at the triangular tip 32 and prevent damage to the triangular tip 32 from friction with the locking post 211.

[0025] like Figure 2 and Figure 3 As shown, a recessed hole 121 is provided on the pressure groove 12, and a second spring 5 is installed in the recessed hole 121. The pressure plate 31 is provided with a contact post 311. The recessed hole 121 is used to accommodate the contact post 311 and the second spring 5. When the pressure plate 31 is pressed, the contact post 311 moves down and compresses the second spring 5. After the pressing stops, the second spring 5 pushes the pressure plate 31 to reset, which facilitates the repeated assembly of the cone 2 by the installation tube 1.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, a fixing hole 122 is provided on the side of the pressure groove 12, and a limiting hole 312 is provided on the contact post 311. A limiting rod 6 is inserted into the fixing hole 122 and the limiting hole 312, and a thread 61 is provided on the limiting rod 6. The limiting rod 6 is provided to fix the push plate 3 and prevent the push plate 3 from accidentally sliding down during the operation of the tap, causing the locking post 211 to disengage from the positioning groove 13, which would then cause the cone 2 and the mounting tube 1 to separate. The thread 61 makes the connection between the limiting rod 6 and the fixing hole 122 stable.

[0027] like Figure 1 and Figure 3 As shown, a countersunk head 123 is provided on the fixing hole 122, and an internal hexagonal groove 62 is provided on the limiting rod 6. The countersunk head 123 is used to accommodate the limiting rod 6, preventing the installation of the mounting tube 1 from being affected when it is installed on the tapping tool, and also making it easier to ensure the aesthetics of the mounting tube 1; the internal hexagonal groove 62 makes it easy to rotate with an internal hexagonal wrench, reducing the space required to rotate the limiting rod 6.

[0028] As shown in the figure, a T-slot 112 is provided on the sliding groove 111, and a guide strip 33 is provided on the push plate 3. The T-slot 112 and the guide strip 33 cooperate to guide the push plate 3 to move, preventing the triangular tip 32 from deviating when it contacts the locking post 211, which would prevent the locking post 211 from exiting the installation groove normally; the guide strip 33 is provided to improve the strength of the push plate 3 and prevent the push plate 3 from bending.

[0029] The working principle of this utility model is as follows: When the cone 2 needs to be replaced, press the pressure plate 31. The pressure plate 31 drives the push plate 3 to move downward. The triangular tip 32 moves downward with the push plate 3 and contacts the inclined surface 211a of the locking post 211. As the triangular tip 32 moves further downward, the locking post 211 moves out of the positioning groove 13. Then the cone 2 separates from the mounting tube 1. After the old cone 2 is removed, the pressure plate 31 is released, so that the pressure plate 31 drives the push plate 3 to reset under the push of the spring 5. The new cone 2 is inserted into the mounting cavity 11 and the locking post 211 is locked into the positioning groove 13, thus completing the replacement.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0031] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
