(B, ) (b) the utility model discloses an electric hoist including the calabash casing, is connected with the link that is used for hanging the calabash on the calabash casing, its characterized in that is constituteed by front and back U -shaped couple with the horizontal pole that a front and back U -shaped couple open end goes on connecting to the link: another open end of front and back U -shaped couple rotates through first pivot and locking board to be connected, and the lower extreme of locking board passes through the second pivot to be connected with the rotation of calabash casing, and the upper end of locking board is equipped with the gib head, and the gib head below is equipped with the buting iron, forms the catching groove between gib head and the buting iron, and the catching groove is just right with the horizontal pole, when the calabash is hung, rely on calabash self weight production opposite direction's rotation between link and the locking board, the catching groove carries out the straining with the whippletree and pins. The utility model discloses be convenient for install and use, simple structure has reliable safety protection function.
Description
Technical field
The utility model relates to a kind of improvement invention of electric block.
Background technology
At present, for the electric block of band link, generally will install the anchor of a band elastic lock in addition on the side of link, complex structure, when installing and using after electric block hangs on lanyard, deviate from from lanyard for avoiding link, manually will operate anchor to be blocked by the opening of link on link by anchor clasp joint, what first bring is operational inconvenience, and what more kill is, if forget by anchor clasp joint on link, serious potential safety hazard can be brought.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and is convenient to install and use, and structure is simple, has the electric block of reliable and secure safeguard function.
The utility model is implemented by following technical solution:
A kind of electric block, comprise gourd shell, gourd shell is connected with the link for hanging cucurbit, link is linked up with by front and back U-shaped and front and back U-shaped is linked up with the cross bar that an open end carries out being connected and form, it is characterized in that: another open end of front and back U-shaped hook is rotationally connected by the first rotating shaft and latch, the lower end of latch is rotationally connected by the second rotating shaft and gourd shell, the upper end of latch is provided with gib head, buting iron is provided with below gib head, form catching groove between gib head and buting iron, catching groove and cross bar are just right; When cucurbit is draped, rely on cucurbit own wt to produce rightabout rotation between link and latch, whippletree is carried out fastening pinning by catching groove.
Have employed the electric block of technique scheme, when electric block is hung on lanyard by link, due to the own wt of cucurbit, so link can be made to rotate along the Impact direction of lanyard, latch can be carried out the stretching of vertical direction again while of link stressed, so rightabout rotation can be produced between latch and link, whippletree is carried out automatic fastening pinning by final catching groove, namely the opening of link is carried out automatically blocking, play prior art to need manually to operate anchor the opening of link is carried out blocking same effect by anchor clasp joint on link, thus avoid link and deviate from from lanyard, what first bring is in operation, the very big convenience installed and used, structure is simple, achieve failure-free function of safety protection simultaneously.Further, the setting of buting iron can prevent lanyard to the promotion of cross bar, catching groove is pinned the fastening of whippletree and does not produce unexpected disengagement by external force affects.
As preferably, the degree of depth of catching groove is greater than the excircle dimension of whippletree.
As preferably, gourd shell rotates at the diagonal position arranging link and is provided with band rope guide ring, portable plate is provided with between band rope guide ring and the rope outlet of cucurbit rope roll, portable plate is externally connected with spacing push pedal, portable plate is located in gourd shell, spacing push pedal is located at outside gourd shell, and spacing push pedal is provided with inclined-plane and limit switch and contacts when restraining position, and limit switch fixedly mounts on gourd shell.
After adopting technique scheme, when arriving restraining position, the band rope on cucurbit rope roll is tightened up encounters portable plate, portable plate drives spacing push pedal to carry out straight line retracting action, until spacing push pedal utilizes its inclined-plane to contact with limit switch, realizes spacing control, structure is simple, reliably spacing.

The utility model has following accompanying drawing:
Fig. 1 is the constructional drawing of the utility model under suspension status (mutually locking between latch and link),
Fig. 2 is the three-dimensional view one of Fig. 1,
Fig. 3 is the three-dimensional view two of Fig. 1,
Fig. 4 is the utility model constructional drawing in its natural state (mutually throwing off between latch and link),
Fig. 5 is cut-away view of the present utility model.
Detailed description of the invention
Details and the principle of work of the utility model specific embodiment is described in detail below in conjunction with accompanying drawing:
As shown in the figure, a kind of electric block of the present utility model, comprise gourd shell 5, gourd shell 5 is connected with the link 1 for hanging cucurbit, link 1 is linked up with 11 by front and back U-shaped and is formed with the cross bar 12 being carried out being connected by front and back U-shaped hook 11 1 open ends, another open end of front and back U-shaped hook 11 is rotationally connected with latch 2 by the first rotating shaft 3, the lower end of latch 2 is rotationally connected with gourd shell 5 by the second rotating shaft 4, the upper end of latch 2 is provided with gib head 21, buting iron 22 is provided with below gib head 21, catching groove 23 is formed between gib head 21 and buting iron 22, catching groove 23 is just right with cross bar 12, the degree of depth of catching groove 23 is greater than the excircle dimension of whippletree 12, when cucurbit is draped, cucurbit own wt is relied on to produce rightabout rotation between link 1 and latch 2, whippletree 12 is carried out fastening pinning by catching groove 23, gourd shell 5 rotates at the diagonal position arranging link 1 and is provided with band rope guide ring 9, portable plate 8 is provided with between band rope guide ring 9 and the rope outlet of cucurbit rope roll, portable plate 8 is externally connected with spacing push pedal 7, portable plate 8 is located in gourd shell 5, spacing push pedal 7 is located at outside gourd shell 5, spacing push pedal 7 is provided with inclined-plane and limit switch 6 and contacts when restraining position, and limit switch 6 fixedly mounts on gourd shell 5.
Electric block of the present utility model, when being hung on lanyard by link 1, due to the own wt of cucurbit, so link 1 can be made to rotate along the Impact direction of lanyard, latch 2 can be carried out the stretching of vertical direction again while of link 1 stressed, so rightabout rotation can be produced between latch 2 and link 1, whippletree 12 is carried out automatic fastening pinning by final catching groove 23, namely the opening of link 1 is carried out automatically blocking, thus avoid link and deviate from from lanyard, achieve failure-free function of safety protection, bring in operation simultaneously, the very big convenience installed and used, structure is simple.
