## Abstract

An assembly includes a nozzle having a curved contact surface curvedly and downwardly extending from two opposite sides of a linear top ridge of the nozzle, a tire pressure sensor having a connection groove with a curved contact surface complementary in shape to and slidable relative to the curved contact surface of the nozzle, and a bolt for fastening the nozzle with the tire pressure sensor. The curved contact surface of the nozzle is slidably movable relative to the curved contact surface of the tire pressure sensor along a specific direction reciprocally so as to adjust a relative connection angle between the sensor and the nozzle and the nozzle is prohibited to move in the connection groove along other directions. Therefore, the work of using the bolt to fasten the tire pressure sensor to the nozzle can be done easily.

## Claims

### Claim 1

A tire pressure sensor and nozzle assembly, comprising:
a nozzle provided with a connection portion having a linear top ridge, a bottom portion opposite to the linear top ridge, and a curved contact surface which curvedly and downwardly extends from two opposite sides of the linear top ridge towards the bottom portion;
a tire pressure sensor provided with a housing having a connection groove in which the connection portion of the nozzle is disposed, the connection groove having a curved contact surface complementary to and slidable relative to the curved contact surface of the connection portion of the nozzle, and
a bolt penetrating through the curved contact surface of the housing of the tire pressure sensor and the curved contact surface of the connection portion of the nozzle to fasten the nozzle and the tire pressure sensor together,
wherein the connection portion of the nozzle has a stop surface stopped at the housing of the tire pressure sensor, and
wherein the stop surface of the connection portion of the nozzle has a curved shape.

### Claim 2 (depends on 1)

The tire pressure sensor and nozzle assembly as claimed in claim 1, wherein the housing of the tire pressure sensor comprises an elongated through hole; the bolt passes through the elongated through hole and is threadedly inserted into the nozzle.

### Claim 3 (depends on 2)

The tire pressure sensor and nozzle assembly as claimed in claim 2, wherein the nozzle includes a through hole into which the bolt is threadedly inserted.

### Claim 4 (depends on 3)

The tire pressure sensor and nozzle assembly as claimed in claim 3, wherein the nozzle includes an inflation hole with an inner end communicated with the through hole of the nozzle, and an outer end communicated with atmosphere and exposed outside the tire pressure sensor.

### Claim 5 (depends on 1)

The tire pressure sensor and nozzle assembly as claimed in claim 1, wherein the nozzle includes a through hole into which the bolt is threadedly inserted.

### Claim 6 (depends on 5)

The tire pressure sensor and nozzle assembly as claimed in claim 5, wherein the nozzle includes an inflation hole with an inner end communicated with the through hole of the nozzle, and an outer end communicated with atmosphere and exposed outside the tire pressure sensor.

### Claim 7 (depends on 1)

The tire pressure sensor and nozzle assembly as claimed in claim 1, wherein the connection groove of the housing of the tire pressure sensor has a curved first stop surface corresponding to the curved stop surface of the nozzle.

### Claim 8 (depends on 1)

The tire pressure sensor and nozzle assembly as claimed in claim 1, wherein the stop surface of the connection portion of the nozzle extends with respect to the linear top ridge orthogonally or at a predetermined included angle.

### Claim 9 (depends on 1)

The tire pressure sensor and nozzle assembly as claimed in claim 1, wherein the connection groove of the housing of the tire pressure sensor has two second stop surfaces, which are opposite to each other and correspond to the stop surface of the nozzle.

### Claim 10 (depends on 9)

The tire pressure sensor and nozzle assembly as claimed in claim 9, wherein the two second stop surfaces are parallel to each other or extend with respect to each other at a predetermined included angle.
