[0032] The inner housing 3 is detachably mounted on the upper end of the transmission block 15;

[0033] The outer shell 2 is detachably mounted on the upper end of the fixing seat 1 and wraps the inner shell 3 therein.

[0034] Please refer to the attached Figure 4 , the springs 13 are all in a semi-compressed state. Specifically, through the above design, the springs 13 can buffer vibrations more quickly and the shaking amplitude of the movable plate 14 can be reduced.

[0035] Please refer to the attached Figure 2 A plurality of heat dissipation ports 31 are provided at the upper end of the inner shell 3, a heat dissipation fan 26 is installed in the outer shell 2, and an air outlet block 27 penetrating the right side of the outer shell 2 is installed on the right side of the outer shell 2.

Specifically, the heat dissipation fan 26 can blow the heat generated by the programmable controller when it is working to the air outlet holes 28 for rapid discharge and heat dissipation.

[0036] Please refer to the attached Figure 5 The path of the air outlet 28 in the air outlet block 27 is S-shaped. Specifically, when the programmable controller and the heat dissipation fan 26 of the device are not started, the S-shaped air outlet 28 can prevent external dust from floating into the outer shell 2.

[0037] Please refer to the attached Figure 2 , Figure 5 The side wall of the outer shell 2 close to the interface end 34 is a rubber sheath 21, and the rubber sheath 21 is provided with a plurality of notches 22 for threading. Specifically, when the programmable controller is not connected, the rubber sheath 21 can prevent dust from entering the outer shell 2. After the programmable controller is connected, the line can pass through the notch 22 while the rubber sheath 21 can still be close to the line to block dust.

[0038] Please refer to the attached Figure 3 A mounting plate 32 is installed at the bottom of the outer shell 2, and a connecting plate 16 is fixedly connected to the upper end of the transmission block 15. The connecting plate 16 and the mounting plate 32 are both provided with connecting ports 33 corresponding to a plurality of positions. Specifically, the connecting plate 16 and the mounting plate 32 are connected by bolts passing through the connecting ports 33.

[0039] Please refer to the attached Figure 2 The outer shell 2 is symmetrically provided with spring pieces 23 extending to the lower end of the outer shell 2 at both the front and rear ends. The spring pieces 23 are provided with a card block 24. The card block 24 is movably connected and matched with the bottom of the fixing seat 1. Specifically, the outer shell 2 can be conveniently disassembled and assembled through the spring pieces 23 and the card block 24.

[0040] Please refer to the attached Figure 1-2 The top of the outer shell 2 is a glass plate 29. Specifically, the above design can facilitate observation of the working conditions of the inner shell 3 and the heat dissipation fan 26 inside the outer shell 2.

[0041] The use principle of a programmable controller with a seismic-resistant structure of the utility model is:

[0042] When assembling the device, firstly connect the programmable controller through the interface end 34 at the side end of the inner housing 3. After the connection is completed, place the mounting plate 32 under the inner housing 3 on the connecting plate 16 on the fixing seat 1, and then adjust the position of the mounting plate 32 so that the mounting plate 32 is aligned with the connecting port 33 on the connecting plate 16. At this time, use a bolt to pass through the mounting plate 32 and the connecting port 33 on the connecting plate 16, then screw it on and tighten the nut to install the inner housing 3.

[0043] Then, the outer shell 2 is buckled on the fixing seat 1 with the side of the rubber cover 21 facing the interface end 34, and the wire connected to the inner shell 3 is inserted into the notch 22. During this process, the front and rear spring pieces 23 of the outer shell 2 need to be opened outwards. When the outer shell 2 is placed on the fixing seat 1, the spring pieces 23 are released. At this time, the spring pieces 23 are reset inwards so that the block 24 extends into the bottom of the fixing seat 1 and fits with the bottom of the fixing seat 1, and the installation of the outer shell 2 is completed.

[0044] When the programmable controller is in use, the heat dissipation fan 26 is started, and the hot air generated by the programmable controller during operation is discharged from the heat dissipation port 31 into the inner housing 3, and the heat dissipation fan 26 blows the hot air to the air outlet 28 so that the hot air is discharged from the outer housing 2 through the air outlet 28 for heat dissipation;

[0045] When vibrated, the inner shell 3 transmits the vibration force to the movable plate 14 through the mounting plate 32, the connecting plate 16 and the transmission block 15. The springs 13 on the six sides of the movable plate 14, namely, up, down, left, right, front and back, buffer the vibration force. Since the spring 13 is in a semi-compressed state, when buffering the vibration, the compression amplitude of the spring 13 is limited, and the recoil force generated by the compression of the movable plate 14 under the influence of the vibration is also large, so that the buffering efficiency is improved and the shaking amplitude of the movable plate 14 will not be too large.

[0046] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
