Description

A push-pull faucet

technical field

The utility model relates to a water faucet, in particular to a pull-press type water faucet. The water faucet is opened and closed by means of pulling and pressing.

Background technique

Existing water tap basically adopts the mode of rotation to open and close water tap. This kind of faucet has two disadvantages: the one is that the screw thread is easily worn out and fails, and the service life of the faucet is not long; the other is that it takes a long time to open and close the faucet. Therefore, designing a water faucet with a long service life and a short time for opening and closing the water faucet has become an important issue for those skilled in the art.

Utility model content

The technical problem to be solved by the utility model is to overcome the disadvantages of the existing faucet, such as short service life and long time for opening and closing the faucet, and provide a pull-press type faucet.

The technical solution adopted by the utility model is: the pull-press type faucet includes a water inlet pipe, the water inlet pipe is in a horizontal direction and the right end has an external thread, and the feature is: the left end of the water inlet pipe is installed with a vertical A cylindrical body, the inner cavity of the water inlet pipe communicates with the inner cavity of the cylindrical body; the bottom of the cylindrical body is provided with an inverted frustum-shaped cylindrical body, and a circular sleeve is installed on the upper part of the cylindrical body. A flange is provided on the top of the sleeve; a rubber sleeve is installed inside the circular sleeve, and flanges are respectively provided on the top and bottom of the rubber sleeve; a tension and compression rod is installed in the rubber sleeve, and the bottom of the tension and compression rod The rounded frustum-shaped rubber stopper is installed, and the top of the pulling and pressing rod is installed with a handle; the taper of the rounded-rounded flat-shaped rubber stopper is equal to the taper of the inner surface of the rounded-rounded frustum-shaped cylinder body, and the diameter of the top of the rounded-rounded platform-shaped rubber stopper is greater than The outer diameter of the middle of the rounded frustum-shaped cylinder.

Explanation of "inverted frustum-shaped cylinder": a vertically placed, upper and lower bottoms are horizontal, and the distance between the midpoint of the lower bottom and a vertical axis outside the figure is smaller than the distance between the midpoint of the upper bottom and the axis The area swept by the parallelogram of the distance when it rotates around the axis for one revolution is equal to the area occupied by the entity of the "inverted frustum-shaped cylinder".

Beneficial effects: the faucet is opened by pulling and closed by pressing. Compared with the existing technology, the time for opening and closing the faucet is shorter; The production cost of the cover is very low, and replacement is not complicated, so the service life of this type of faucet is very long.

Detailed ways

Below in conjunction with Fig. 1 to Fig. 2, the utility model will be further described: a pull-press type faucet, comprising a water inlet pipe 8, the water inlet pipe 8 is in a horizontal direction and has an external thread at the right end, it is characterized in that: the water inlet pipe 8 The left end of the cylinder body 5 in the vertical direction is installed, and the inner cavity of the water inlet pipe 8 communicates with the inner cavity of the cylinder body 5; A round sleeve 3 is installed on the top of the cylinder body 5, and a flange is provided on the top of the round sleeve 3; a rubber sleeve 4 is installed inside the round sleeve 3, and flanges are respectively provided on the top and bottom of the rubber sleeve 4 ; Pull and push rod 2 is installed in the rubber sleeve 4, and the bottom of the pull and push rod 2 is installed with a rounded table body shape rubber stopper 4, and the top of the pull and push rod 2 is equipped with a handle 1; The taper is equal to the taper of the inner surface of the inverted frustum-shaped cylinder 7 , and the diameter of the top of the inverted frustum-shaped rubber stopper 4 is greater than the outer diameter of the middle part of the inverted frustum-shaped cylinder 7 .

The narrative sequence of the technical solutions of the utility model is different from the installation sequence of the parts of the water tap. When installing, first install the rounded table-shaped rubber plug on the lower part of the tension and compression rod, install the rubber sleeve in the round sleeve, then insert the upper part of the tension and compression rod into the rubber sleeve, and then install the rounded table-shaped rubber plug and the tension and compression rod. The rod is inserted into the cylindrical body, the circular sleeve is installed on the upper part of the cylindrical body, and finally the handle is installed.

The handle can be a plate or a stick. The circular sleeve, the cylindrical body, the water inlet pipe, the rounded truncated cylindrical body, and the tension and compression rods are made of metal materials, and the circular sleeve and the cylindrical body are interference fit. The cylinder body, the water inlet pipe, and the inverted frustum-shaped cylinder body can be produced as a whole. The rubber stopper can be glued to the bottom of the tension and compression rod. After the rubber stopper closes the water tap, the top surface of the rubber stopper bears water pressure, which is beneficial to the sealing between the rubber stopper and the rounded frustum-shaped cylinder. There is an interference fit between the tension and compression rod and the rubber sleeve to prevent tap water from leaking out from the upper part of the faucet; because the rubber sleeve has greater elasticity, the pressure of the rubber sleeve on the tension and compression rod is small and does not affect the movement of the tension and compression rod .

The water inlet pipe is used to be connected with the water pipe. The top of the round sleeve is provided with a flange to facilitate the removal of the round sleeve from the cylindrical body during maintenance.
