Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1 and 2, the present embodiment provides a liquid level meter, which includes a housing 1, a detection probe 2 installed in the housing 1, a socket 3 disposed at an end of the housing 1 far from the detection probe 2, and a plug 4 adapted to the socket 3; the number of the probes 2 may be two or more, and is not limited herein.

The socket 3 is in a circular tube shape, and the outer wall of the upper end of the socket 3 is provided with a threaded section 31; the plug 4 is cylindrical and is inserted into the socket 3. The outer wall of the upper part of the plug 4 is provided with a ring-shaped groove 41.

The liquid level detection meter in the embodiment further comprises a locking sleeve 5 sleeved on the plug 4 and a dustproof cover 6 detachably mounted on the socket 3 and used for plugging the socket 3.

In the embodiment, the locking sleeve 5 includes a top plate 51 movably nested in the annular groove 41, it should be noted that the top plate 51 can rotate or move up and down in the annular groove 41, and cannot be drawn out from the annular groove 41 under the limitation of the annular groove 41, so as to ensure that the whole locking sleeve 5 and the plug 4 are integrated, and the locking sleeve 5 cannot be lost.

As shown in fig. 3, the locking sleeve 5 in this embodiment further includes a sleeve 52 fixedly mounted on the lower wall of the top plate 51 for penetrating and sleeving the outer wall of the socket 3; the lower end of the sleeve 52 has a first thread groove 521 on its inner wall for fitting the thread section 31. Therefore, after the plug 4 is inserted into the socket 3, only the sleeve 52 needs to be rotated, the locking sleeve 5 can be installed on the outer wall of the socket 3 in a threaded manner under the matching of the first threaded groove 521 and the threaded section 31, and finally the lower wall of the top plate 51 can be pressed against the lower wall of the annular groove 41 along with the continuous rotation of the sleeve 52, so that the sleeve 52 cannot be rotated continuously, and at the moment, the plug 4 cannot be directly pulled out of the socket 3 under the limitation of the sleeve 52 and the top plate 51, so that the connection strength of the plug 4 and the socket 3 is ensured; and the design of the annular groove 41 can ensure that the whole locking sleeve 5 has a space for up-and-down displacement in the annular groove 41, thereby ensuring that the plug 4 can be smoothly inserted into the socket 3.

In order to facilitate the installation of the dust cap 6, in this embodiment, the inner side wall of the dust cap 6 is provided with a second thread groove 61 adapted to the thread section 31, so that after the plug 4 is taken down, only the dust cap 6 needs to be installed on the socket 3 through a rotating thread. Therefore, the threaded section 31 on the socket 3 can be used for mounting the locking sleeve 5 and the dust cap 6, so that the threaded section 31 is fully utilized.

In order to facilitate the free-hand rotation of the locking sleeve 5 and the dust cap 6, and the outer wall of the sleeve 52 are provided with friction ribs 8 in this embodiment. The dust cover 6 or the sleeve 52 can be rotated easily by rubbing the ribs 8 to enhance the friction between the human hand and the dust cover 6 or the sleeve 52.

In order to reduce the influence of the liquid level fluctuation on the detection of the probe 2, a plurality of kidney-shaped holes 11 are formed on the outer wall of the lower part of the shell 1 in the embodiment. The influence of the liquid level fluctuation on the detection can be reduced through the kidney-shaped hole 11.

In order to facilitate the installation of the detector, in this embodiment, an installation plate 7 is fixedly connected to the outer wall of the housing 1 on the side close to the socket 3, wherein installation holes 71 are formed in the plate walls on both sides of the installation plate 7.

The implementation principle is as follows: when the plug 4 needs to be inserted for use, the locking sleeve 5 on the plug 4 is firstly pulled to the uppermost end of the annular groove 41, then the plug 4 is aligned with the socket 3, the socket is inserted into the socket 3, then the lower end of the sleeve 52 is aligned with the outer wall of the socket 3, the sleeve 52 starts to rotate, the sleeve 52 can gradually displace downwards along with the continuous rotation of the sleeve 52, the top plate 51 is pressed against the bottom wall of the annular groove 41, and at the moment, the plug 4 cannot be drawn out from the socket 3 under the limitation of the top plate 51 and the sleeve 52.

When the detector is used, the plug 4 is pulled down; the dust cap 6 can be rotated to the socket of the socket 3, and then the dust cap 6 blocks the socket of the socket 3 to prevent dust from entering the socket of the socket 3.

Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
