Description

Technical Field

[0001] The utility model relates to the technical field of placement racks, in particular to an adjustable placement rack. Background Art

[0002] Aluminum anode refers to the electrode used as anode material in the aluminum electrolysis process. Aluminum anode usually uses petroleum coke, asphalt coke, etc. as aggregate, coal tar, etc. as binder, and is processed into carbon paste or carbon block. When placing the aluminum anode, it needs to be placed on a placement rack or hanger.

[0003] For example, publication number CN212025485U discloses a special hanger for aluminum anodizing. The special hanger for aluminum anodizing is provided with a No. 1 clamp, a No. 2 clamp, a No. 3 clamp, a No. 1 adjustment mechanism, a No. 2 adjustment mechanism and a telescopic mechanism, which are used in conjunction with each other to stably clamp the aluminum anodized workpiece, eliminating the trouble of opening a hanging hole in the plate-like workpiece and can clamp a larger number of aluminum anodized workpieces at one time.

[0004] When placing aluminum anodes, in order to accommodate aluminum anodes with different spacings, the above patent rotates the fastening bolt and the adjusting ring for threaded transmission, so that the fastening bolt is disengaged from the connection with the sliding column, and then the adjusting ring is moved to drive the sliding plate equipped with the clamp to move. After the adjustment is completed, the fastening bolt is disengaged from the sliding column and contacted again by rotating the fastening bolt to complete the spacing adjustment. This adjustment method is relatively cumbersome and is not convenient for rapid adjustment of the placement rack. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable placement rack to solve the problem that the existing placement racks proposed in the above background technology are inconvenient to adjust.

[0006] To achieve the above object, the utility model provides the following technical solution: an adjustable placement rack, comprising: a rack body and a connecting rod, wherein two sides of the rack body are provided with sliding grooves for sliding movable plates, and the interior of the rack body is fixedly connected with a fixed block,

[0007] A moving block is arranged on one side of the movable plate.

[0008] Preferably, one side of the moving block is connected to a first spring, one end of the first spring is connected to a connecting sleeve, one side of the connecting sleeve is fixedly connected to the movable plate, and both sides of the movable plate are provided with through grooves for sliding the slide rod.

[0010] Preferably, the outer side of the bidirectional threaded rod is threadedly connected to a threaded block, both ends of the bidirectional threaded rod are movably connected to the frame body through bearings, both sides of the threaded block are movably connected to connecting rods through rotating shafts, and one side of the connecting rod is movably connected to the movable plate through a rotating shaft.

[0011] Preferably, both sides of the frame are provided with sliding grooves for sliding a slider on one side of the connecting block, a second spring is fixedly connected inside the connecting block, and one end of the second spring is fixedly connected to a clamping rod.

[0012] Preferably, a first clamping slot and a second clamping slot for the clamping rod to engage are provided inside the frame body, and a movable slot for the lever to rotate is provided inside the clamping rod.

[0013] Preferably, one side of the lever is movably connected to the connecting block via a rotating shaft, the bottom of the connecting block is movably connected to a supporting rod via a rotating shaft, and a side of the frame body close to the supporting rod is fixedly connected to an inclined block.

[0014] Compared with the prior art, the adjustable placement rack has the following beneficial effects: by turning the handle, the small gear and the large gear are driven to mesh, so that the bidirectional threaded rod and the two groups of threaded blocks are threadedly transmitted, driving the two groups of threaded blocks to approach each other in relative directions, and when the two groups of threaded blocks move, the four groups of connecting rods are driven to rotate, and the unfolded connecting rods can push the two groups of movable plates to move, so that the spacing between the fixed block and the movable block changes, and the lever is driven to disengage the engaging rod from the second slot, and then the connecting block is moved down so that the support rod contacts the ground, and the lever can be released at this time, and the second spring will reset and push the lever into the first slot to complete the fixation of the connecting block, and the support rod can support both sides of the rack.

[0015] 1. When placing aluminum anodes, the aluminum anodes need to be supported by a placement rack. In order to make the spacing of the placement rack adapt to the size of the aluminum anodes, the small gear is driven to mesh with the large gear by turning the handle, and the large gear can drive the bidirectional threaded rod to rotate. The rotation causes the bidirectional threaded rod to perform threaded transmission with the two sets of threaded blocks, driving the two sets of threaded blocks to approach each other in relative directions. When the two sets of threaded blocks move, they will drive the four sets of connecting rods to rotate. The unfolded connecting rods can push the two sets of movable plates to move, so that the spacing between the fixed block and the movable block changes. The sliding rod can limit the movable plate. When the spacing adjustment is completed, the handle can be released. In this way, the above operation can facilitate the adjustment of the spacing between the fixed block and the movable block in the placement rack, so as to facilitate the placement of aluminum anodes of different sizes.

[0016] 2. When placing the aluminum anode, it is necessary to support the aluminum anode through the placement rack. In order to make the placement of the placement rack more stable, the lever is pushed in the movable groove of the clamping rod. When the clamping rod is disengaged from the second clamping groove, the connecting block can be moved downward. When the bottom of the connecting support rod contacts the inclined surface of the inclined block, it will rotate and unfold. When the support rod contacts the ground, the lever can be released, and the second spring will reset and push the clamping rod into the first clamping groove to complete the fixation of the connecting block. At this time, the support rod can support both sides of the frame. In this way, the above operation can facilitate the support of the frame and make it stably placed.
