Description

Technical Field

[0001] This utility model relates to the field of busbar processing technology, and in particular to a spreading tool. Background Technology

[0002] Busbars are components installed inside electrical control cabinets for bus connections. To improve the safety of the electrical control cabinet, heat shrink tubing needs to be fitted onto the busbars. However, to facilitate the installation of busbars, they are usually processed into Z-shaped or L-shaped structures. For Z-shaped busbars, it is inconvenient to fit the heat shrink tubing. If the fitting is done before molding, the heat shrink tubing is easily damaged during bending. If heat shrinking is done after bending, the fitting becomes more difficult. Utility Model Content

[0003] This utility model provides a spreading tool to overcome the shortcomings of the prior art and solve the problem of the difficulty in installing the busbar after deformation, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A spreading fixture includes a base plate, a vertical plate mounted on one end of the base plate, two pairs of vertically arranged guide grooves on the vertical plate, movable rods movably mounted within the guide grooves, and movable blocks at one end of the movable rods at the same height. A connector is provided on the outer wall of the movable block, and a connecting plate is hinged to the connector. A lead screw is rotatably mounted on the vertical plate, and a rotating head is provided on the outer end of the lead screw. A movable seat is screwed onto the lead screw, and a pair of guide lugs are provided on the movable seat. A guide rod passes through the guide lugs and is mounted on the vertical plate. The movable seat has a... The moving head is hinged to the other end of the connecting plate. Through the set movable rod, it acts on the inside of the heat shrink tubing, thereby opening the heat shrink tubing into a rectangular structure, which facilitates the installation of the heat shrink tubing and reduces the difficulty of installation. After the heat shrink tubing is opened, only the busbar needs to be inserted into the heat shrink tubing. The set connecting plate and other components can ensure that the movable rod moves outward synchronously to open the heat shrink tubing, thereby avoiding excessive local tension on the movable rod, which could cause the heat shrink tubing to break.

[0006] Furthermore, to facilitate the rotation of the rotating head, a dumbbell bar is inserted through the rotating head.

[0007] Furthermore, the cross-section of the movable rod is circular to avoid damaging the heat shrink tubing when it is opened.

[0008] Further, in order to avoid the heat shrink tube contraction force to make the other end of the movable rod inwardly bent, thereby affecting the busbar penetrating operation, a rectangular frame is installed at the other end of the bottom plate, a pair of movable seats are movably arranged at the upper and lower ends of the rectangular frame, a hinge plate is hinged to the inner side end of the movable seat, a lug is hinged to the other end of the hinge plate, a strutting plate is arranged at the inner side end of the lug at the same height, the other end of the movable rod is penetrated in the strutting plate, guide rails are installed at the two sides of the interior of the rectangular frame, the two ends of the strutting plate are movably arranged on the guide rails, strutting screws are rotatably arranged at the upper and lower ends of the rectangular frame, the screw threads of the two ends of the strutting screws are opposite, the movable seat is arranged at the two ends of the strutting screw, and a rotating cap is arranged at one end of the strutting screw, so that the other end of the movable rod can be fixed through the strutting plate.

[0009] The above technical scheme has the advantages of:

[0010] The utility model discloses convenient for the sleeve setting operation of busbar heat shrink tube, and in the process of sleeve setting, through the strutting of heat shrink tube without damage, thereby facilitating the heat shrink operation of busbar. ACCURACY OF DRAWINGS
