Description

Probe mounting structure of temperature detector

Technical Field

A probe mounting structure of a temperature detector belongs to the field of temperature detector fixing structures, and particularly relates to probe fixing.

Background

The probe of the temperature detector is frequently touched with a hard object during the use and carrying process. The fixing mode of the probe of the existing temperature detector is that corresponding mounting grooves are usually arranged on an upper shell and a lower shell, then the probe is placed on the mounting grooves, and the probe is fixed after the upper shell and the lower shell are assembled and mounted. The fixing mode enables the fixing groove of the probe to be divided into an upper part and a lower part, and the lever force and the like formed in the using process of the probe enable the mounting groove to be easily deformed, so that the probe is loosened, the contact point of the probe and an internal part is loosened, and the service life of the temperature detecting instrument is further influenced; after the probe loosens, water vapor and corrosive gas enter the temperature detector through a gap between the probe and the shell to damage parts.

SUMMERY OF THE UTILITY MODEL

The technical problem is as follows: the fixing mode of the probe of the existing temperature detector enables the fixing groove of the probe to be divided into an upper part and a lower part, and the lever force and the like formed in the using process of the probe can enable the fixing groove to be easily deformed, so that the probe is loosened, the contact point of the probe and an internal part is loosened, and the service life of the temperature detector is further influenced; after the probe loosens, water vapor and corrosive gas enter the temperature detector through a gap between the probe and the shell to damage parts.

The technical scheme is as follows: a probe mounting structure of a temperature detector comprises a probe, a needle sleeve, a mounting shell and a rear cover. The mounting shell is provided with a fixing hole for mounting the probe, and the probe is in close fit with the fixing hole; the needle sleeve is provided with a through hole for the probe to pass through; the needle sleeve is sleeved outside the probe fixing position after the installation shell, the rear cover and the probe are combined.

Preferably, the fixing holes include a front fixing hole and a rear fixing hole.

Furthermore, the hole length of the front fixing hole is 8-12 mm, and the hole length of the rear fixing hole is one quarter of the hole length of the front fixing hole.

Preferably, the through hole in the needle sleeve is in interference fit with the probe.

Preferably, the needle sleeve is made of silica gel.

Preferably, the needle sleeve is made of hard plastic.

Has the advantages that: the utility model relates to a temperature detection instrument's probe mounting structure adopts probe and the closely complex mode of fixed orifices, and the probe can be by firmly fixing in the fixed orifices. The fixing hole is formed by a front hole and a rear hole, so that the probe is fixed more firmly. The needle sleeve is sleeved outside the probe fixing position of the combined mounting shell, the rear cover and the probe, so that the product is attractive and elegant, and the strength of the probe fixing position is further enhanced when the needle sleeve is made of a hard plastic material; when the needle cover is made of a silica gel material, the needle cover and the probe are in interference fit to play a sealing role, and the front part of the shell can be protected from being corroded and damaged by the silica gel which has a corrosion-resistant effect.

Fig. 1 is an overall view of the present invention;

fig. 2 is an exploded view of the present invention;

fig. 3 is a partial enlarged view of the present invention.

In the figure, 1 is a probe, 2 is a needle sleeve, 3 is a mounting shell, 4 is a rear cover, 5 is a fixing hole, 5-1 is a front fixing hole, and 5-2 is a rear fixing hole.

Detailed Description

The technical scheme of the utility model is explained in detail by selecting a better implementation mode with the attached drawings.

The first embodiment is as follows: a probe mounting structure of a temperature detector comprises a probe 1, a needle sleeve 2, a mounting shell 3 and a rear cover 4. The front end of the mounting shell 3 is provided with a fixing hole 5 for mounting the probe 1, the fixing hole 5 comprises a front fixing hole 5-1 and a rear fixing hole 5-2, the length of the front fixing hole 5-1 is 8-12 mm, and the length of the rear fixing hole is one fourth of the length of the front fixing hole. In the embodiment, the front fixing holes 5-1 are 8 mm long, and the rear fixing holes 5-2 are 2 mm long. The probe 1 is tightly matched with the fixing hole 5; and after the probe is matched with the fixing hole 5, AB glue is applied to the joint of the probe and the hole on the surface corresponding to the front fixing hole 5-1 and the rear fixing hole 5-2 for sealing. Because the coaxiality of the front fixing hole and the rear fixing hole can have deviation in the production process, the length of the rear fixing hole is small, and the outline of the rear fixing hole can slightly deform, the combination of the front fixing hole and the rear fixing hole enables the probe to be firmly fixed.

The matching part of the front end of the rear cover 4 and the fixing hole 5 on the mounting shell 3 is provided with a groove with the outline shape similar to that of the fixing hole 5. The needle sleeve 2 is sleeved outside the probe fixing position after the installation shell 3, the rear cover 4 and the probe 1 are combined. The needle sleeve 2 is made of hard plastic. This not only makes the overall structure aesthetically pleasing to the atmosphere, but also the needle hub 2 can further strengthen the strength of the overall mounting structure.

The installation process comprises the following steps: the probe 1 is inserted into the fixing hole 5 on the mounting shell 3, and AB glue is applied to the joint of the probe and the hole on the corresponding surface of the front fixing hole 5-1 and the rear fixing hole 5-2 for sealing. Then cover back lid 4, fix back lid 4 and installation shell 3 with the screw, cover the probe cover 2 outside of the probe fixed position after installation shell 3, back lid 4 and the combination of probe 1 behind the probe end of probe 1.

Example two: the needle cover 2 is made of silica gel, and the through hole in the needle cover 2 is in interference fit with the probe 1. Therefore, the integral structure is attractive and atmosphere, the sealing effect of the needle sleeve 2 is further enhanced, and the damage of parts caused by the fact that water vapor, corrosive gas and the like enter the temperature detector through the fixing structure of the probe can be avoided; the silica gel has the function of corrosion resistance, so the needle sleeve can also protect the front part of the shell from being corroded and damaged. The rest is as described in the first embodiment.
