[0015] Further, it also includes peripheral organizations;

[0016] The peripheral mechanism includes a reinforcement block, an isolation grid and connecting wires;

[0017] The reinforcing block is fixed to the middle of the upper end of the control body, and the isolation grid is fixed to the middle section of the rear lower part of the control body. One end of the connecting wire extends to the middle of the lower end of the back of the control body.

[0039] See also Figure 1-4 As shown, this embodiment is a combustible gas alarm controller, comprising:

[0040] An alarm control mechanism, the alarm control mechanism comprises a control body 11 and a cabinet door 12;

[0041] The cabinet door 12 is hinged to the middle of the front of the control body 11;

[0042] The control body 11 is used as the main control structure for combustible gas alarm control, and the cabinet door 12 provides frontal protection for the control body 11 and can be opened to inspect and repair the internal components of the control body 11;

[0043] The alarm control mechanism also includes a display screen 13, a button 14 and an indicator light 15;

[0044] The display screen 13 is embedded in the upper middle section of the front face of the cabinet door 12, and the buttons 14 are equidistantly embedded in the middle section of the front face of the cabinet door 12, and the indicator lights 15 are equidistantly embedded in the lower middle section of the front face of the cabinet door 12;

[0045] The display screen 13 displays data and instructions, the button 14 operates the instructions, and the indicator light 15 is used for data indication;

[0046] The locking mechanism includes a mounting housing 21, a lock core 22, a lock hole 23, a movable block 24 and a pressure sensor 25;

[0047] The mounting shell 21 is fixed to the lower part of one side of the front of the cabinet door 12, and the lock core 22 is fixed in the middle of the front of the mounting shell 21, the lock hole 23 is opened in the middle of the front of the lock core 22, and the movable block 24 slides dampingly on one side of the middle of the lock core 22, and the pressure sensor 25 is fixed in the middle of one side of the front of the movable block 24 and protrudes forward;

[0048] The housing 21 is installed to install the lock core 22. The cabinet door 12 can be locked by the lock core 22 to protect the control body 11 from the outside. The lock hole 23 is used to open and close the lock core 22. The movable block 24 is used to shield the lock hole 23 from the outside to prevent foreign objects from entering the lock hole 23 and affecting normal use. The pressure sensor 25 is also installed to sense pressure, which can be used as a basis for judging whether the lock hole 23 is damaged.

[0049] The front part of the movable block 24 is cross-shaped, the rear part is semicircular, and the pressure sensor 25 has a built-in wireless transmitter;

[0050] The cross-shaped arrangement is conducive to external shielding and protection of the lock hole 23, and the wireless transmitter is used to send the detected data to the outside;

[0051] Working principle: After the cabinet door 12 is opened and the interior of the control body 11 is regularly inspected and repaired, the cabinet door 12 can be closed again. After the cabinet door 12 is closed, the lock core 22 is re-locked through the lock hole 23 with a key, and the cabinet door 12 is locked;

[0052] After locking the lock hole 23, the movable block 24 is pushed inwards so that the front cross-shaped structure of the movable block 24 covers the lock hole 23 again. When a malicious force is applied to the movable block 24, the pressure sensor 25 at the front feels the pressure, and the built-in wireless transmitter can be used to send data to the outside.

[0053] This step can provide timely knowledge of the situation, facilitate subsequent timely processing and reduce losses.

[0054] See also Figure 1-4 As shown, this embodiment is based on the above-mentioned embodiment 1;

[0055] It also includes external institutions;

[0056] The peripheral mechanism includes a reinforcing block 41, an isolation grid 42 and a connecting wire 43;

[0057] The reinforcing block 41 is fixed to the middle of the upper end of the control body 11, and the isolation grid 42 is fixed to the middle section of the lower rear portion of the control body 11, and one end of the connecting wire 43 extends to the middle of the lower rear end of the control body 11;

[0058] The reinforcing block 41 strengthens the structure of the upper end of the control body 11 to extend its service life. The isolation grid 42 isolates the heat dissipation opening at the rear end of the control body 11 and meets the requirements of normal heat dissipation. The connecting wire 43 connects the control body 11 to electricity.

[0059] Also included is a protective shielding mechanism;

[0060] The protective shielding mechanism includes a hole block 31, an upper isolation frame 33 and a lower isolation frame 34;

[0061] The hole blocks 31 are symmetrically fixed to the front end of the isolation grid 42, and the upper isolation frame 33 is threaded on the inner side of the upper group of hole blocks 31, and the lower isolation frame 34 is threaded on the inner side of the lower group of hole blocks 31;

[0062] The hole block 31 is used to install the upper isolation frame 33 and the lower isolation frame 34. When the upper isolation frame 33 and the lower isolation frame 34 are closed, the isolation grid frame 42 can be shielded from the outside to prevent dust from adhering to the surface of the isolation grid frame 42, thereby increasing the subsequent cleaning intensity. When the lower isolation frame 34 is opened, the connecting wire 43 to be connected can be structurally limited, which is convenient for use.

[0063] A threaded column 32 is threaded through the middle of the hole block 31, and the inner thread of the threaded column 32 extends to the end of one side of the upper isolation frame 33 and the lower isolation frame 34;

[0064] The threaded column 32 fixes the upper isolation frame 33, the lower isolation frame 34 and the hole block 31. The threaded connection method is conducive to rotation and can ensure the stability of the structure after rotation.

[0065] The other end of the upper isolation frame 33 is provided with columnar protrusions at equal distances, and the other end of the lower isolation frame 34 is provided with semicircular grooves at equal distances;

[0066] The columnar protrusion can seal the semicircular groove, which can form a fully enclosed environment after the upper isolation frame 33 and the lower isolation frame 34 are closed;

[0067] Working principle: When shielding the unused isolation grid 42, apply an inward force to the upper isolation frame 33 and the lower isolation frame 34 in turn, and rotate the thread until the upper isolation frame 33 and the lower isolation frame 34 rotate to an angle parallel to the control body 11, and the multiple columnar protrusions on the upper isolation frame 33 extend into the multiple semicircular grooves on the lower isolation frame 34;

[0068] When the internal heat dissipation of the control body 11 is performed, the above-mentioned reverse steps can be applied, and after the lower isolation frame 34 is unfolded, one end of the connecting wire 43 to be connected can be clamped in the semicircular groove;

[0069] This step improves the applicability and functionality of the structure.
