Utility Model Content

[0003] In order to improve the efficiency of suspension heat treatment, the present application provides a multi-layer heat treatment suspension hanger.

[0004] The multi-layer heat treatment suspension hanger provided in this application adopts the following technical solution:

[0005] A multi-layer heat treatment suspension hanger includes a hanger and a fixed hanging basket arranged at the bottom end of the hanger, and also includes a movable hanging basket. The hanger peripheral wall is provided with a flip groove in the vertical direction, and a support rod is arranged in the flip groove. The top of the support rod is rotatably connected to the inner wall of the flip groove. The bottom wall of the movable hanging basket is provided with a mounting groove for the support rod to be inserted into, and the bottom wall of the support rod is provided with a yield groove. A first connecting rod is rotatably connected in the flip groove, and the other end of the first connecting rod is hinged to a second connecting rod, and the other end of the second connecting rod is hinged to the inner wall of the yield groove. The support rod is provided with a locking piece for fixing the first connecting rod and the second connecting rod.

[0006] By adopting the above technical scheme, when the number of workpieces that need to be hot-processed is small, the workpieces can be placed in a fixed hanging basket for heat treatment. If the movable hanging basket is not installed, the pressure on the lifting device can also be reduced. When the number of workpieces that need to be hot-processed is large, the support rod is rotated so that the support rod becomes a horizontal position. The first connecting rod and the second connecting rod rotate under the rotation of the support rod. The positions of the first connecting rod and the second connecting rod are fixed by the locking member, and then the support rod can be positioned. At this time, the movable hanging basket can be loaded on the support rod through the installation groove, thereby improving the efficiency of heat treatment when the number of workpieces is large.

[0008] By adopting the above technical solution, the threaded column is rotated and connected into the threaded hole. When the first connecting rod and the second connecting rod are unfolded, the locking hole parts respectively located on the first connecting rod and the second connecting rod will be in a coaxial position. At this time, the staff can push the locking pin into the locking tube so that the locking tube can be coaxial with the locking hole. Under the action of the elastic member, the locking pin extends out of the locking tube again and enters the locking hole, thereby completing the locking of the first connecting rod and the second connecting rod. At this time, the first connecting rod and the second connecting rod will not be able to continue to rotate to achieve the locking of the support rod. The locking member of the present application has a simple structure, has the advantages of being relatively convenient to install and disassemble, and has high practicality.

[0009] Optionally, an adjustment groove is provided on the peripheral wall of the locking tube along the length direction, the adjustment groove is connected to the interior of the locking tube, and a shift block is provided on the peripheral wall of the locking pin, one end of the shift block extends out of the adjustment groove.

[0010] By adopting the above technical solution, the shift block extends out of the adjustment slot, which makes it easy for the staff to adjust the position of the locking pin by sliding the shift block, thereby achieving high convenience.

[0011] Optionally, a clamping groove is formed on an inner side wall of one end of the adjustment groove away from the locking pin.

[0012] By adopting the above technical solution, when the shift block reaches the top of the adjustment groove, the shift block is rotated so that the shift block can be screwed into the snap-in groove. Under the action of the snap-in groove, the elastic part will not be able to drive the locking pin to reset, so that the staff can install or disassemble the locking part conveniently, which is highly convenient.

[0013] Optionally, the threaded hole is opened through the supporting rod, a positioning hole is opened on the inner wall of the installation groove corresponding to the threaded hole, and one end of the threaded column passes through the threaded hole and is threadedly connected to the inner wall of the positioning hole.

[0014] By adopting the above technical solution, after the threaded column is connected to the positioning hole, the movable hanging basket and the supporting rod can be locked, thereby effectively preventing the movable hanging basket from falling off during the lifting process.

[0015] Optionally, a toggle groove is formed on a surface of the support rod facing away from the flip groove.

[0016] By adopting the above technical solution, the toggle groove is provided to facilitate the staff to flip the supporting rod out of the flip groove, thereby improving the ease of use of the suspension sling of the present application.

[0017] Optionally, a reset member is provided at the rotational connection between the support rod and the flip groove, and the reset member enables the support rod to maintain a rotational tendency toward the flip groove.

[0018] By adopting the above technical solution, the presence of the reset part ensures that the support rod can always remain in the flip groove when there is no need to install the movable hanging basket, so as to prevent the support rod from falling out of the flip groove and colliding with other parts during the lifting process, thereby improving stability and safety.

[0019] Optionally, the suspension rod includes an outer tube and an adjusting rod threadedly connected to the outer tube, one end of the adjusting rod extends out of the top wall of the outer tube, and the flip groove is provided on the peripheral wall of the outer tube.

[0020] By adopting the above technical solution, the suspension rod is configured in the form of an outer tube and an adjusting rod, so that the overall length of the suspension rod can be adjusted, thereby improving the flexibility of the suspension device of the present application.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. When a large number of workpieces need to be hot-processed, the support rod is rotated so that the support rod becomes a horizontal position. The first connecting rod and the second connecting rod rotate under the rotation of the support rod. The positions of the first connecting rod and the second connecting rod are fixed by the locking member, so that the support rod can be positioned. At this time, the movable hanging basket can be loaded on the support rod through the mounting groove, thereby improving the operating efficiency of the heat treatment when a large number of workpieces are present;
