SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel key switch case to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a novel key switch valve core comprises a first part and a second part movably connected with the first part; and one end of the first part is provided with a slot, and is in adaptive connection with a plug pin arranged on the second part through the slot.
As the utility model discloses a preferred technical scheme: the first portion is in threaded connection with the faucet through an external thread, and a first mounting groove is formed in one end, far away from the faucet, of the external thread.
As the utility model discloses a preferred technical scheme: the one end that the external screw thread is close to tap is equipped with the second mounting groove, and first mounting groove with install the sealing washer in the second mounting groove.
As the utility model discloses a preferred technical scheme: the first part and the second part are both provided with water inlet holes; the water inlet holes and the slots are arranged alternately, and the cross sections of the water inlet holes and the slots are rectangular.
As the utility model discloses a preferred technical scheme: the inner wall of the first part is provided with a notch, and the notch is connected with the lug boss arranged on the second part in a matched mode.
Adopt above-mentioned technical scheme, the beneficial effects of the utility model are that: 1. the movable connection between the first part and the second part is realized through the adaptive connection between the slot and the bolt;
2. because the first part and the second part are movably connected, the connection mode is more convenient for assembling the first part and the second part compared with the existing threaded connection, and the manufacturing mode of the device is simpler compared with the manufacturing of threads, so that the manufacturing processes of the two parts are reduced;
3. the two are assembled in an inserting mode, so that the device is not required to be specially fixed, and the two do not need to rotate mutually; thereby thoroughly avoiding the problems of threaded connection.

Fig. 1 is a schematic exploded view of the present invention;
FIG. 2 is a schematic view of the main structure of the first part of the present invention;
fig. 3 is a schematic view of the main structure of the second part of the present invention.
In the figure: 1. a first portion; 10. a first mounting groove; 11. a second mounting groove; 12. a notch; 13. a water inlet hole; 14. a slot; 15. an external thread; 2. a second portion; 20. a bolt; 21. and (4) a boss.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Referring to fig. 1-3, the present invention provides an embodiment: a novel key switch valve core comprises a first part 1 and a second part 2 movably connected with the first part 1; one end of the first part 1 is provided with a slot 14, and is in adaptive connection with a bolt 20 arranged on the second part 2 through the slot 14. Due to the fact that the first part 1 and the second part 2 are movably connected, compared with the existing threaded connection, the connection mode is more convenient for assembling the first part and the second part, compared with the mode of manufacturing threads, the device is simpler in manufacturing mode, and manufacturing processes of the two parts are reduced.
In order to solve the problem that when the first part 1 of the existing key switch valve core is connected with a water tap, the thread on the inner wall of the water tap easily punctures the sealing ring to cause sealing failure of the first part 1 and the water tap, the first part 1 is in threaded connection with the water tap through the arranged external thread 15, a first mounting groove 10 is arranged at one end, far away from the water tap, of the external thread 15, and the first mounting groove 10 is arranged at one end, far away from the water tap, of the first part 1, so that the sealing ring in the first mounting groove 10 is not in contact with the thread on the inner wall of the water tap, and the sealing performance of the device is further improved.
