DETAILED DESCRIPTION

[0023] See also Figure 1-7 , a transfer device for a fume hood, comprising an adjustment mechanism 1, a limiting mechanism 2 is arranged on the surface of the adjustment mechanism 1;

[0024] The adjusting mechanism 1 enables the device to be spliced ​​with each other to adapt to fume hoods of different widths, and the limiting mechanism 2 enables the fume hood to be limited.

[0025] The adjustment mechanism 1 includes a movable cart 101, and mounting grooves 102 are arranged on all four sides of the movable cart 101. A connecting plate 107 is slidably connected to the surface of the mounting groove 102. A slot 108 and a positioning groove 109 are provided on the surface of the connecting plate 107. A first screw 113 is threadedly penetrated at the four corners of the bottom of the movable cart 101. A sleeve 103 is arranged above the connecting plate 107. A connecting rod 106 is fixed to the bottom of the sleeve 103. An extension rod 104 is slidably connected to the surface of the sleeve 103. A side plate 105 is fixed to the surface of the extension rod 104. A connecting frame 111 is fixed to the surface of the movable cart 101. A mounting plate 110 is rotatably connected to the surface of the connecting frame 111. A plurality of rollers 112 are rotatably connected to the surface of the mounting plate 110.

[0026] The surface of the movable cart 101 is used to place the fume hood. When placing the fume hood, the bottom of the fume hood can contact the surface of the roller 112, and the roller 112 can reduce friction by rotating, so that the operator can more easily push the fume hood to the surface of the movable cart 101, and the extension rod 104 can be matched with the side plate 105 to limit the two sides of the movable cart 101, and the extension rod 104 can slide on the inner wall of the side plate 105 to adapt to fume hoods of different heights. At the same time, the mounting plate 110 can be rotated upward, so that the mounting plate 110 and the roller 112 can limit one side of the movable cart 101, thereby further preventing the fume hood from detaching from the surface of the movable cart 101. When multiple movable carts 101 are spliced, the surface cover 103 of the connecting plate 107 on one side is taken out , so that the connecting rod 106 is disengaged from the slot 108, at which time the shell 103 on one side of the movable cart 101 together with the extension rod 104 will be separated from the surface of the movable cart 101, and then the connecting plate 107 is inserted into the mounting groove 102 on the surface of the movable cart 101 on the other side, so that the surfaces of the two movable carts 101 can be spliced ​​with each other, and then the first screw rod 113 is rotated so that the top of the first screw rod 113 can enter the positioning groove 109, thereby completing the fixation of the connecting plate 107, so that the two spliced ​​movable carts 101 can be limited, and then the device can be flexibly adjusted according to the actual layout of the laboratory fume hood, and can be used alone or combined with other movable carts 101 to form a larger transportation system, which is convenient for carrying fume hoods with larger volume and heavier weight.

[0027] Furthermore, the limiting mechanism 2 includes a combination plate 201, which is fixed to the surface of the side plate 105, a second screw 202 is threaded through the surface of the combination plate 201, a movable plate 203 is rotatably connected to the surface of the second screw 202, a spring 204 is fixed to the surface of the movable plate 203, and a clamping plate 205 is fixed to the surface of the spring 204;

[0028] Rotating the second screw 202 can move the movable plate 203 so that the clamping plate 205 can be close to the fume hood. When the clamping plate 205 contacts the surface of the fume hood, the spring 204 will be compressed, so that the fume hood can obtain a flexible clamping effect, making it difficult for the fume hood to move on the surface of the movable cart 101.

[0029] Furthermore, a pin rod 115 is passed through the surface of the housing 103, and a plurality of adjustment holes are opened on the surface of the extension rod 104;

[0030] After the extension rod 104 is adjusted to a position inside the casing 103 , the extension rod 104 can be limited by passing the pin 115 through the casing 103 and the adjustment hole.

[0031] Furthermore, a movable rod 119 is fixed on the surface of the extension rod 104 on one side, and the surface of the movable rod 119 is rotatably connected to a limiting plate 120;

[0032] The limiting plate 120 can move on the surface of the movable rod 119. After the mounting plate 110 rotates upward, the limiting plate 120 can be rotated downward so that the surface of the limiting plate 120 blocks the mounting plate 110, so that the mounting plate 110 will not rotate by itself.

[0033] Furthermore, a limiting sleeve 114 is provided at the bottom of the mounting groove 102, the top of the limiting sleeve 114 is fixedly connected to the bottom of the movable cart 101, a fastening bolt 117 is passed through the surface of the limiting sleeve 114, and a limiting nut 118 is threadedly connected to the surface of the fastening bolt 117, and a mounting hole for matching the fastening bolt 117 is opened on the surface of the connecting rod 106;

[0034] After the bottom of the connecting rod 106 is inserted into the slot 108 and the limiting sleeve 114, the fastening bolt 117 can be passed through the limiting sleeve 114 and the connecting rod 106, and the limiting nut 118 can be screwed into the surface of the fastening bolt 117, so that the connecting rod 106 can obtain a limiting effect, thereby ensuring the stability of the housing 103 when the movable cart 101 moves.

[0035] Furthermore, a positioning wire 116 is passed through the surface of the pin rod 115, and the positioning wire 116 is made of elastic metal material;

[0036] After the positioning wire 116 is inserted into the pin rod 115 , the pin rod 115 can obtain a limiting effect, so that the pin rod 115 will not separate from the surface of the housing 103 by itself.

[0037] Furthermore, guide rods 206 are passed through the surfaces of the combined plate 201 and the movable plate 203, and one end of the guide rod 206 is fixedly connected to the surface of the clamping plate 205;

[0038] When the movable plate 203 moves, the guide rod 206 can slide on the surface of the combined plate 201 and the movable plate 203, so that the movable plate 203 and the clamping plate 205 can obtain a guiding effect, thereby preventing the movable plate 203 from rotating.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
