[0014] Next, we will further explain the instrument housing air tightness detection tooling described in the utility model in conjunction with the accompanying drawings.

[0015] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0016] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense; for example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] See also Figure 1-2 As shown in, an instrument case air tightness detection tool comprises a base 1; it is characterized in that it also comprises a pressing tool 2 mounted on the base 1 for fixing and rotating the instrument case on the base 1, a plurality of vents 11 arranged on the base 1 and an air pump connected to the vents 11 through pipelines; the pressing tool 2 comprises a pressing seat 21, a fixing fixture 22 and a connecting rod 23 movably mounted on the pressing seat 21, a handle 24 movably connected to the fixing fixture 22 and the connecting rod 23, and a clamping rod 25 mounted on the fixing fixture 22;

[0018] Through the setting of this device, the air tightness of the instrument shell can be quickly tested, the structure is simple, the operation is convenient and fast, and the work efficiency is high;

[0019] When pressing the instrument case, the instrument case is placed on the base 1, and then the operator pushes the handle 24, which drives the fixing clamp 22 and the connecting rod 23 to move, thereby driving the clamping rod 25 to move downward to press the instrument case. When loosening the instrument case, the operator pulls the handle 24 backward, and the handle 24 drives the fixing clamp 22 and the connecting rod 23 to move backward, thereby driving the clamping rod 25 to move upward to loosen the instrument case.

[0020] In one embodiment, it also includes a positioning block 3 installed on the base 1 to position the installation position of the instrument case; the positioning block 3 is set to position the instrument case to ensure that the position of the vent hole 11 is aligned with the position of the column welded on the instrument case, thereby ensuring the accuracy of the air tightness test; at the same time, for different types of instrument cases, the corresponding positioning block 3 can be replaced with the corresponding type of positioning block 3 for use.

[0021] In one embodiment, a rubber pad 4 is further included which is installed on the clamping rod 25. The rubber pad 4 acts as a buffer when the clamping rod 25 presses the instrument case, thereby preventing deformation of the instrument case caused by hard contact between the clamping rod 25 and the instrument case.

[0022] In one embodiment, it also includes a sealing ring 5 installed at the vent hole 11. Through the setting of the sealing ring 5, when the instrument case is pressed, the sealing ring 5 is squeezed to increase the sealing between the instrument case and the vent hole 11, so as to avoid affecting the accuracy of the instrument case air tightness detection due to leakage.

[0023] In one embodiment, the fixing clamp 22 is provided with an adjustment slot 6 for adjusting the position of the clamping rod 25. By setting the adjustment slot 6, the position of the clamping rod 25 on the fixing clamp 22 can be adjusted according to actual conditions. The clamping rod 25 is fixedly installed on the fixing clamp 22 by a nut. When adjusting, the position of the clamping rod 25 can be moved by loosening the nut. After the position adjustment is completed, the nut can be tightened.

[0024] When the utility model is in use: first, the instrument case is placed on the base 1 and positioned by the positioning block 3, and then the operator pushes the handle 24 forward to drive the clamping rod 25 to press the instrument case, and after the instrument case is pressed, the air pump is started, and the air pump inflates the vent 11 through the pipeline. At this time, the operator applies water or foam water to the edge of the column welding in the instrument case. If there is a leakage, the operator can directly observe it through the water and foam water. If there is no reaction to the water or foam water, it means that there is no leakage and the air tightness is good. After the detection is completed, the clamping rod 25 is loosened, and then the instrument case is removed to carry out the detection of the next instrument case.

[0025] The protection scope of the present utility model is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present utility model.
