Description

  The present invention relates to a valve stem, and more particularly to a valve stem with a connection cap for a tire pressure detector applied to a truck.

  Referring to FIG. 5, a conventional track valve stem (60) has an outer portion (62), an inner portion (64) and a sealing nut (66). The inner portion (64) is integrally formed coaxially with the outer portion (62), and protrudes from the inner surface of the rim toward the tire attached to the rim. The inner part (64) has a terminal face and a keyed recess (642). A sealing nut (66) is movably mounted on the outer part (62) and is used to securely clamp the rim with the inner part to mount a track valve stem (60) on the rim. .

  On the other hand, since people have been paying more attention to safe driving these days, tire pressure detection integrally attached to the inner side of the track valve stem (60) in order to monitor the air pressure in the tire. The vessel is recently popular and well received. The tire pressure detector continuously transmits an electromagnetic wave signal about the air pressure to the tire pressure monitoring system (TPMS) so that the air pressure can be always read.

  However, if the tire pressure detector breaks or fails, it is necessary to replace the entire track valve package with the integrally mounted tire pressure detector, which is wasteful.

  The present invention provides a valve stem with a connection cap for a tire pressure detector to eliminate or mitigate the disadvantages of conventional track valve stems that cannot be connected to a wireless pressure detector.

  The main object of the present invention is to provide a valve stem with a connection cap for a tire pressure detector in order to improve the wireless pressure detector so that it can be attached to the connection cap and valve stem.

  A valve stem with a connection cap for a tire pressure detector comprises a body, a connection cap and a fastener. The main body is tubular and is a valve stem applied to a truck, and has an outer portion, an inner portion and a fixing nut. The inner portion is integrally formed coaxially with the outer portion and has an outlet hole formed in the inner portion. The fixing nut is movably and rotatably mounted on the outer portion. The connection cap is cylindrical, has an outer end and a hole, and is removably attached to the inner portion. The hole is coaxially formed in the connection cap in the longitudinal direction. The fastener corresponds to the hole and the outlet hole and holds a wireless pressure detector at the outer end of the connection cap.

  The advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

  1, 2, 3 and 4, a valve stem with a connection cap for a truck tire pressure detector according to the present invention includes a body (10), a connection cap (20), and a fastener (30). ).

  The body (10) is tubular and is applied to the track and comprises an outer part (12), an inner part (14) and a fixing nut (16).

  The inner part (14) is formed coaxially and integrally with the outer part (12) and has a distal end and an outlet (142).

  The outlet (142) is formed coaxially and longitudinally through the inner portion (14) at the distal end and has a threaded inner surface (1422).

  The fixing nut (16) is movably mounted on the outer part (12), can be brought close to the inner part (14), and tightens the rim (52) of the tire (54) together with the inner part (14) Used for

  The connection cap (20) is cylindrical and is removably attached to the end of the inner part (14). The connection cap (20) has an inner end, an outer end, a dome-shaped surface and a hole (22), and may have at least one clamping surface (24).

  The inner end of the connection cap (20) corresponds to the end of the inner part (14) and is removably attached to the end.

  The dome-shaped surface is formed at the outer end of the connection cap (20).

  The hole (22) is formed in the lateral direction coaxially through the connection cap (20) from the inner end to the outer end.

  The clamping surface (24) is tangentially formed on the annular surface of the connection cap (20). Preferably, a plurality of pairs of clamping surfaces (24) parallel to each other are formed on the annular surface of the connection cap (20).

  The fastener (30) corresponds to the hole (22) and the threaded inner surface (1422), through which the wireless pressure detector (40) is secured to the dome-shaped surface of the connection cap (20). To be attached to a threaded inner surface (1422). The fastener (30) has an air passage (32) that penetrates the fastener in the longitudinal direction.

  Therefore, the wireless pressure detector (40) can be easily attached to the main body (10) after the main body (10) is securely attached to the rim (52) of the tire (54). Furthermore, the attitude of the wireless pressure detector (40) relative to the connection cap (20) and the body (10) can be adjusted along the dome-shaped surface of the connection cap (20), so that the wireless The pressure detector (40) can be placed close to the rim (52) so that when the tire (54) is under pressure, it is less susceptible to damage by the tire.

  Although the foregoing describes various features and advantages of the present invention, along with details of the structure and operation of the present invention, the disclosure is for purposes of illustration only. Changes in detail within the scope of the principles of the invention, in particular, changes in shape, size and arrangement, to the fullest extent indicated by the broad general meaning of the terms set forth in the appended claims. Is possible.
