[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-5As shown, the utility model provides a drawer-type contactor, including a box body 1, a contactor body 2 is provided in the middle of the box body 1, two mirror-distributed first sliders 21 are fixedly installed at the bottom of the contactor body 2, two mirror-distributed fixed blocks 3 are provided at the lower part of the box body 1, and limit blocks 34 are slidably inserted in the middle of the two fixed blocks 3, and handles 35 are fixedly installed at the bottom ends of the two limit blocks 34, and symmetrically distributed second sliders 33 are fixedly installed on both sides of the two limit blocks 34, and springs 32 are fixedly installed in the middle of the four second sliders 33, and two symmetrically distributed second sliders 33 are provided in the middle of the two fixed blocks 3. The third slide groove 31 of the cloth, the four second sliders 33 are all slidably clamped in the inside of the third slide groove 31, the ends of the four springs 32 away from the second sliders 33 are fixedly installed in the middle of one side of the third slide groove 31, and the middle of one side of the box body 1 is fixedly installed with a fixing box 15. By setting the third slide groove 31 and limiting the second slider 33 by the third slide groove 31, the second slider 33 is pushed by the reaction force of the spring 32 to move in the inside of the third slide groove 31, thereby driving the limit block 34 to move, thereby limiting and fixing the first slider 21, that is, limiting and fixing the contactor body 2.

[0018] A motor 16 is fixedly installed in the middle of one side of the fixed box 15, and a cooling fan 17 is provided on one side of the motor 16. The middle of one side of the cooling fan 17 is fixedly installed on the driving end of the motor 16. By arranging the motor 16 and the cooling fan 17, the cooling fan 17 is driven by the motor 16 to rotate, so that the heat generated by the contactor body 2 is blown out through the heat dissipation hole 18 by the cooling fan 17, so that the air inside the box body 1 can circulate, thereby cooling the contactor body 2.

[0019] The lower part of the box body 1 is provided with two mirror-distributed cavities 14 , and the two fixing blocks 3 are fixedly installed inside the cavities 14 . By providing the cavities 14 , the device for limiting and fixing the contactor body 2 can be conveniently installed and placed.

[0020] A limiting groove 341 is provided in the middle of the opposite sides of the two first sliders 21, and one side of the two limiting blocks 34 is slidably clamped inside the limiting groove 341. By setting the limiting groove 341, the second slider 33 is pushed under the reaction force of the spring 32, which drives the limiting block 34 to move outward, so that it is inserted into the limiting groove 341, and the second slider 33 can be limited, so that the contactor body 2 can be limited and fixed.

[0021] Two mirror-distributed first slide grooves 12 are provided at the bottom of the box body 1, and the two handles 35 are slidably clamped inside the first slide grooves 12. By setting the first slide grooves 12 and clamping the first slide grooves 12, it is convenient to squeeze the handles 35 toward the middle at the same time, so that the limit block 34 can be driven to leave the inside of the limit groove 341. At this time, the contactor body 2 is pulled, and the contactor body 2 and the first slider 21 can be pulled out from the inside of the box body 1.

[0022] Two second slide grooves 13 with mirror-image distribution are provided on the inner upper surface of the box body 1, and the two first sliders 21 are slidably clamped inside the second slide grooves 13. By setting the second slide grooves 13, by setting the second slide grooves 13, and by limiting the first sliders 21 through the second slide grooves 13, it is convenient to slide and limit the contactor body 2 inside the box body 1.

[0023] A plurality of heat dissipation holes 18 distributed in an array are provided on one side of the box body 1 close to the fixing box 15. By providing the heat dissipation holes 18, the heat generated by the contactor body 2 is blown out through the heat dissipation holes 18 under the rotation of the heat dissipation fan 17, so that the internal air circulates, thereby cooling the contactor body 2.

[0024] Support seats 11 are fixedly installed at the four corners of the bottom end of the box body 1. By providing the support seats 11, it is convenient to place the box body 1 stably.

[0025] Working principle: In actual use, by aligning the first slider 21 with the second slide groove 13 and pushing the contactor body 2, the contactor body 2 can be moved inward through the second slide groove 13. When the first slider 21 contacts the limit block 34, the limit block 34 will be squeezed to make the limit block 34 move inward. At the same time, by moving inward, the spring 32 is squeezed and stored. When the first slider 21 moves inward so that the limit groove 341 and the limit block 34 are aligned with each other, at this time, the second slider 33 is pushed outward by the reaction force of the spring 32, that is, the limit block 34 is pushed outward so that one side of the limit block 34 is stuck in the inside of the limit groove 341, that is, the first slider 21 is fixed, thereby the contactor body 2 is limited and fixed. By squeezing the handle 35 toward the middle at the same time, the limit block 34 can be driven to leave the inside of the limit groove 341. At this time, the contactor body 2 is pulled, and the contactor body 2 and the first slider 21 can be pulled out from the inside of the box body 1.

[0026] By starting the motor 16 installed in the middle of the fixing box 15, the cooling fan 17 is driven to rotate by the motor 16, so that the heat generated by the contactor body 2 is blown out through the heat dissipation holes 18 by the cooling fan 17, so that the air inside the box body 1 can circulate, thereby cooling the contactor body 2.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
