Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1 to 4, the embodiment describes an automobile expansion kettle assembly with a liquid level detection function, which includes an apparatus body 1, two first guide rods 11 are vertically arranged inside the apparatus body 1, the first guide rods 11 are symmetrically arranged at the bottom of the inner wall of the apparatus body 1, a first floating plate 12 and a second floating plate 13 are sleeved on the outer peripheral surfaces of the two first guide rods 11 together, and a detection assembly 2 is arranged on the apparatus body 1; the detection assembly 2 can detect the liquid level inside the device body 1.
The first floating plate 12 is positioned below the second floating plate 13, the first floating plate 12 is similar to the transverse base plane of the second floating plate 13, and a water storage space 3 is arranged between the first floating plate 12 and the second floating plate 13;
the area of the first floating plate 12 is 0.7-0.8 times of the cross-sectional area of the second floating plate 13. In the present embodiment, the area of the first floating plate 12 is 0.8 times the cross-sectional area of the second floating plate 13.
The top of the second floating plate 13 is provided with a plurality of first through holes 131. The first through-hole 131 facilitates the passage of liquid through the second floating plate 13.
The detection assembly 2 comprises a first shell 21 and a second shell, the first shell 21 is fixed at the top of the device body 1, the second shell vertically penetrates through the inside of the device body 1, and the second shell is communicated with the inside of the first shell 21;
a gravity block 23 is arranged in the second shell in a sliding manner, a second guide rod 25 is horizontally arranged in the first shell 21, a sliding block 26 is sleeved on the outer peripheral surface of the second guide rod 25 in a sliding manner, and a pull rope 24 is fixedly connected between the sliding block 26 and the gravity block 23;
a pull rod 27 is fixed on the side of the slide block 26 away from the pull rope 24, and one end of the pull rod 27 extends to the outside of the first housing 21. A pulling plate 271 is fixed to one end of the pull rod 27 located outside the first housing 21. The operator pulls the pull rod 27, the pull rod 27 drives the sliding block 26 to move, the sliding block 26 drives the pull rope 24 to move, and the pull rope 24 drives the gravity block 23 to move upwards along the height direction of the second shell.
Third through holes 221 are formed in two sides of the second shell, fourth through holes 4 are formed in the first floating plate 12 and the second floating plate 13, and the fourth through holes 4 are matched with the second shell in shape; the first floating plate 12 and the second floating plate 13 are provided with a connecting rod 41 at a position corresponding to the fourth through hole 4, and the connecting rod 41 passes through the third through hole 221. Since the link 41 passes through the second housing, the weight block 23 may touch the link 41 when the weight block 23 moves inside the second housing. A second through hole 261 is formed in one side of the sliding block 26, and the second guide rod 25 penetrates through the second through hole 261; a plurality of placing grooves 262 are formed in one side of the inner wall of the second through hole 261, balls 263 are movably placed in the placing grooves 262, and the balls 263 are in point contact with the second guide rod 25.
The main working principle of the implementation is as follows:
inside the apparatus body 1, water enters the water storage space 3, and at this time, the space between the first floating plate 12 and the second floating plate 13 is filled with water.
The operator needs to detect the actual level of liquid inside the device body 1.
The operator pulls the pulling plate 271, the pulling plate 271 drives the pulling rod 27 to move, and the pulling rod 27 drives the sliding block 26 to move along the linear direction of the second guide rod 25. The slide block 26 moves the pull cord 24. In this description, the pull cord 24 is always in a taut state. And the length of the pull rope 24 does not change in the long-term operation of the pull rope 24.
The vertical cross section of the slide block 26 corresponds to the vertical cross section of the first housing 21, and dust and foreign substances are prevented from entering the inside of the apparatus body 1 through the gap between the slide block 26 and the first housing 21.
The pull rope 24 drives the gravity block 23 to move along the height direction of the second shell. During the movement of the gravity block 23, the gravity block 23 eventually touches the connecting rod 41.
Since the water storage space 3 is internally filled with liquid. After the weight block 23 hits the link 41, the operator will experience a significantly greater resistance to pulling the pull rod 27 than was previously experienced when pulling the pull rod 27. At this time, the operator keeps the length of the existing tie rod 27 constant.
Looking at the scale on the pull rod 27.
It is noted that the scale on the pull rod 27 is drawn according to the actual operation. When the gravity block 23 is located at the bottom of the second casing, the scale of the joint between the pull rod 27 and the first casing 21 is 0, and in an experiment, according to the length of the extension of the pull rod 27 when the liquid level rises by 10mm, the scale of the joint between the pull rod 27 and the first casing 21 is 10 mm. Finally, according to the standard, scales are sequentially marked on the pull rod 27. And finally, carrying out mass production.
In the present embodiment, in order to ensure that the measurement accuracy is accurate. The pull cord 24 may be made of steel chain.
When the operator releases the pull rod 27, the pull rod 27 returns to the initial position due to the weight block 23.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
