DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0032] Please refer to Figures 1-4 In the embodiments of the present application, a gas tightness detector comprises:

[0033] The detector main body 1 integrates a gas circuit system, a detection sensor, a control circuit and a display module 2. A display operation panel 3 corresponding to the display module 2 is arranged on one side surface of the detector main body 1, and is used for displaying detection data and receiving operation instructions.

[0034] The protection assembly comprises a first protection structure 4 and a second protection structure 5, wherein,

[0035] The first protection structure 4 is arranged outside the display operation panel 3, is adapted to the display operation panel 3, and is used for protecting the display operation panel 3. An elastic buffer component 6 is arranged at the edge of the first protection structure 4.

[0036] The second protection structure 5 is arranged at a corner position of the detector main body 1, comprises a high-strength shell 7 and an internal buffer 8, and is connected with the detector main body 1 through bolts or buckles.

[0037] In the technical solutions of the present application, the first protection structure 4 is customized and designed according to the shape and size of the display operation panel 3, so as to be closely and accurately arranged outside the display operation panel 3. The adaptive design can ensure the comprehensiveness of protection, and will not leave a dead angle of protection due to size deviation. The elastic buffer component 6 is arranged at the edge of the first protection structure 4. When an external force impacts, the elastic buffer component 6 first contacts the external force and deforms elastically. The deformation process can absorb impact energy, convert impact kinetic energy into elastic potential energy, thereby reducing the impact force transmitted to the display operation panel 3, and avoiding damage to the panel due to directly bearing a large impact force.

[0038] The second protection structure 5 adopts a high-strength shell 7, such as high-strength metal or engineering plastic material, when the edge of the detector main body 1 is impacted, the high-strength shell 7 can directly bear most of the external impact force due to its high-strength characteristics, preventing the external force from directly acting on the edge of the detector main body 1, and avoiding rapid deformation due to the weak structure of the edge; the internal buffer 8 is arranged inside the high-strength shell 7, when the high-strength shell 7 bears the impact force, part of the energy will be transmitted to the internal buffer 8, the internal buffer 8 further absorbs and disperses the energy by its deformation, such as compression, distortion, etc., reducing the energy transmitted to the inside of the detector main body 1, preventing the internal gas path system, control circuit and other key components from being damaged due to the impact of the edge;

[0039] In summary, the first protection structure 4 and the elastic buffer component 6 of the edge can effectively reduce the damage to the display operation panel 3 caused by accidental contact of the operator, instrument carrying collision and the like; the high-strength shell 7 and the internal buffer 8 of the second protection structure 5 work together to significantly improve the anti-impact ability of the edge of the detector main body 1, reduce the deformation of the shell caused by the edge collision, and further avoid the problems of internal gas path system leakage, poor circuit connection and the like, thereby ensuring the normal work of the key components such as the gas path system, the detection sensor and the control circuit, and improving the accuracy and stability of the detection result of the air tightness detector.

[0040] In the embodiment of the utility model, the display operation panel 3 has a frame 9 protruding on the surface of the detector main body 1, the first protection structure 4 is provided with a clamping groove 10 matched with the shape of the frame 9 on the side edge facing the display operation panel 3, and the first protection structure 4 is clamped and matched with the frame 9 through the clamping groove 10.

[0041] The frame 9 of the display operation panel 3 protrudes on the surface of the detector main body 1, and the clamping groove 10 designed on the first protection structure 4 is matched with the shape of the frame 9, which is based on size measurement and shape simulation to ensure that the clamping groove 10 can tightly surround the frame 9, so that the first protection structure 4 can be quickly and accurately positioned during installation, thereby fixing the relative position of the protection structure and the display operation panel 3, preventing installation deviation or misplacement, and laying a foundation for the realization of subsequent protection function;

[0042] The first protection structure 4 is clamped and matched with the frame 9 through the clamping groove 10, and the connection is achieved by mechanical engagement between the clamping groove 10 and the frame 9. The inner side wall of the clamping groove 10 forms a surrounding clamping force on the frame 9, which can prevent the first protection structure 4 from displacing or falling off relative to the display operation panel 3 when subjected to external force. The clamping and matching can be considered as interference clamping, which is beneficial to installation and replacement when the first anti-slip structure is damaged. Of course, corresponding buckles / clamping grooves 10 or bolt connection can be added between the first protection structure 4 and the frame 9 for further reinforcement;

[0043] The first protection structure 4 is in the form of a frame with a protective screen, the protective screen is made of a transparent material with high impact resistance, such as polycarbonate, and is tightly combined with the frame by an integrated molding process or a high-strength bonding method; the protective screen is located directly in front of the display operation panel 3 and directly resists impact and scratches from the front; the frame is connected to the frame 9 of the display operation panel 3 through the clamping groove 10 to provide support and positioning for the protective screen, ensuring that the protective screen is always in the correct position and protecting the display operation panel 3 in all directions.

[0044] In the embodiment of the utility model, the elastic buffer component 6 is in a continuous ring structure and is arranged around the entire edge of the first protection structure 4 away from the display operation panel 3; or,

[0045] The elastic buffer component 6 is four independent units and is arranged at the four corner positions of the edge of the first protection structure 4 away from the display operation panel 3.

[0046] The continuous ring-shaped elastic buffer component 6 is arranged around the entire edge of the first protection structure 4 away from the display operation panel 3, and its design is based on the need for all-around buffering and protection. When the first protection structure 4 is subjected to external force impact from all directions, the continuous ring structure can form a complete buffer belt, which can uniformly disperse the impact force from a mechanical point of view, avoiding local stress concentration.

[0047] The elastic buffer component 6 is designed as four independent units and is arranged at the four corner positions of the edge of the first protection structure 4 away from the display operation panel 3, considering that in actual use scenarios, the four corners of the first protection structure 4 are the most easily impacted parts, and the impact force borne by the corners is relatively concentrated. By arranging independent elastic buffer units at these key positions, the high risk of the corners can be protected.

[0048] The elastic buffer component 6 can be a material or structure with elastic and buffering properties, such as natural rubber, nitrile rubber, polyurethane sponge, EVA sponge, etc., or a gas-filled airbag, etc.

[0049] In the embodiment of the utility model, the edge and corner positions of the detector main body 1 are provided with bosses 11, the inner side of the high-strength shell 7 is correspondingly provided with grooves 12 adapted to the bosses 11, and the internal buffer 8 can be embedded in the inner groove.

[0050] The boss 11, the internal buffer 8 and the high-strength shell 7 are provided with coaxial bolt holes 13, bolts are sequentially threaded through the bolt holes 13 of the high-strength shell 7 and the internal buffer 8 and are screwed with the bolt holes 13 of the boss 11, so as to fix and install the high-strength shell 7 and the internal buffer 8 at the corner position of the detector main body 1.

[0051] The boss 11 is arranged at the corner position of the detector main body 1, and the high-strength shell 7 is provided with an adaptive groove 12 on the inner side, which is based on the principle of accurate structure matching, and the boss 11 and the groove 12 are adapted to provide an accurate positioning mode for the high-strength shell 7 and the internal buffer 8 during installation; during installation, the groove 12 on the inner side of the high-strength shell 7 is aligned with the boss 11 at the corner of the detector main body 1, so that the installation position of the protection structure can be quickly and accurately determined, and deviation or misplacement during installation is avoided, thereby ensuring the accuracy and consistency of the installation of the second protection structure 5.

[0052] The boss 11, the internal buffer 8 and the high-strength shell 7 are provided with coaxial bolt holes 13, bolts are sequentially threaded through the bolt holes 13 and are screwed, and the bolt connection utilizes the mechanical engagement characteristics of the thread, so that when the bolt is tightened, the friction between the threads can generate strong fastening force, and the high-strength shell 7, the internal buffer 8 and the detector main body 1 are tightly connected together.

[0053] The internal buffer 8 can be embedded in the groove 12 on the inner side of the high-strength shell 7, on the one hand, the groove 12 provides a stable installation space for the internal buffer 8 and limits the displacement of the internal buffer 8 during use, so that the internal buffer 8 is always in a position capable of effectively playing a buffering role; on the other hand, when subjected to an external impact, the high-strength shell 7 transmits the impact force to the internal buffer 8, and the embedded groove 12 design enables the internal buffer 8 to better cooperate with the high-strength shell 7 to jointly absorb and disperse the impact force, thereby effectively avoiding the impact force acting directly on the corner of the detector main body 1.

[0054] The material of the internal buffer 8 can be foam rubber, sponge or honeycomb energy-absorbing material; according to the fact that the corners of the air-tightness detector main body 1 are usually right-angle structures, the high-strength shell 7 and the internal buffer 8 are also right-angle pieces.

[0055] In the embodiment of the utility model, the outer surface of the high-strength shell 7 is formed with a reinforcing rib position 14.

[0056] Through the design of the reinforcing rib position 14, the structural strength of the high-strength shell 7 is further improved, and the protection of the detector main body 1 is better achieved.

[0057] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
