[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses an outer shell for industrial instruments, referring to Figure 1, including an instrument housing 1, a shell cover 2 is provided at the front end of the instrument housing 1, and a plurality of card slots are opened on the outer wall of the shell cover 2, and the card slots are composed of a circular groove and a convex groove. A plurality of placement sleeves 3 are fixedly connected to the inner wall of the instrument housing 1, and a slider 4 is slidably connected to the inner wall of the placement sleeve 3. A connecting rod 5 is rotatably connected to the front end of the slider 4, and a spring 6 is fixedly connected to the outer wall of the slider 4. The other end of the spring 6 is fixedly connected to the inner wall of the placement sleeve 3, and a block 7 is fixedly connected to the rod body of the connecting rod 5. The connecting rod 5 is pulled so that the block 7 can pass through the inside of the card slot and extend to the front end of the instrument housing 1. One side of the block 7 is tightly fitted with the front end outer wall of the shell cover 2, and the connecting rod 5 can be rotated so that the block 7 is no longer aligned with the surface of the card slot. The inner wall of the instrument housing 1 is provided with a plurality of connecting components;

[0021] Specifically, refer to Figure 4 The connecting assembly includes a fixing sleeve 10, a sliding rod 11, a convex plate 12 and a spring 13. The outer walls of the fixing sleeves 10 are fixedly connected to the plurality of fixing sleeves 10. The front end of the instrument housing 1 is provided with a plurality of mounting grooves. The inner walls of the mounting grooves are fixedly connected to the sliding rod 11. The rod bodies of the sliding rods 11 are slidably connected to two convex plates 12. Both sides of the spring 13 are fixedly connected to the convex plates 12. The convex plates 12 are snap-fitted with the fixing sleeve 10. When the shell cover 2 is attached to the surface of the instrument housing 1, the fixing sleeves 10 on both sides of the shell cover 2 will squeeze the two convex plates 12, so that the convexities of the convex plates 12 are attached to the surface of the fixing sleeve 10 under the elastic force of the spring 13, so as to facilitate the fixing of the shell cover 2.

[0022] Reference Figure 2 A ventilation plate 14 is fixedly connected to the upper end of the instrument housing 1 to facilitate ventilation and heat dissipation of the interior of the instrument housing 1. Two shielding plates 15 are slidably connected to the upper surface of the ventilation plate 14. The two shielding plates 15 can be slid to cover the ventilation plate 14 to prevent dust and other debris from entering the interior of the instrument housing 1.

[0023] Reference Figure 2 The front end outer wall of the instrument housing 1 is fixedly connected with two fitting rods 9 to facilitate the placement of the housing cover 2. The rod body of the fitting rod 9 is tightly fitted with the housing cover 2.

[0024] Reference Figure 3 The front end outer wall of the shell cover 2 is fixedly connected with a plurality of retaining rings 8, and the surface of the retaining rings 8 is provided with retaining grooves, so that the card block 7 can be fitted inside the retaining groove, so that the card block 7 can be fixed to the shell cover 2 through the elastic force of the spring 6.

[0025] The implementation principle of the outer shell for industrial instruments in the embodiment of the present application is as follows: when in use, the shell cover 2 is placed on the surface of the instrument housing 1, the connecting rod 5 and the block 7 are aligned with the slot, and the shell cover 2 is placed on the surface of the instrument housing 1. When the shell cover 2 is attached to the surface of the instrument housing 1, the fixing sleeves 10 on both sides of the shell cover 2 will squeeze the two convex plates 12, so that the protrusions of the convex plates 12 are attached to the surface of the fixing sleeves 10 under the elastic force of the spring 13, which is convenient for fixing the shell cover 2. At the same time, the connecting rod 5 is pulled and rotated, so that the block 7 on the rod body of the connecting rod 5 is attached to the inside away from the slot. When rotating, the block 7 can be attached to the inner wall of the retaining ring 8, and the elastic force of the spring 6 makes the block 7 fit tightly with the shell cover 2, which is convenient for fixing the shell cover 2.
