Description
Technical field
The utility model belongs to the technical field as the ladder of ascending tool, is specifically related to a kind of double ladder tool shelf.
Background technology
People often need to realize ascend operation by ladder in producing and living.Double ladder is a kind of ladder of commonly using, comprises front ladder and rear ladder.Double ladder can be divided into again front ladder and the two-sided double face ladder that all can climb of rear ladder, and front ladder and rear ladder wherein one side climb the only single face ladder for supporting of another side, general front ladder and rear ladder all have two vertical rods, between two vertical rods as the one of climbing surface in front ladder and rear ladder, establish some crosspieces, the place of marking time that when this crosspiece was namely climbed as the people, pin was stepped on.
Existing double ladder has two problems: the one, there is no special-purpose tool shelf, so the staff can only carry instrument and use, or upper and lower ladder is taken instrument repeatedly, thus instrument take use very inconvenient; The 2nd, after the front ladder of double ladder and rear terraced cross bearing, climb while using, on climbing surface, the first rank and the second-order crosspiece of number can not be trampled from the top down, because if when the people stood on first, second rank crosspiece, center of gravity can be too high, easily from ladder, to turn down, danger increases greatly.
The utility model content
The utility model provides a kind of double ladder tool shelf, all can provide the instrument bearing surface after being assemblied on dissimilar double ladder, and the instrument of being convenient to the staff uses; In addition, the support that is plugged on the tool shelf on double ladder is equivalent to the climbing surface of double ladder has been extended upward, the position that can grasping is provided, lean on when the people trample first, second rank crosspiece of double ladder, avoid people's crank and turn down from ladder, therefore uses safer; Locking mechanism on described tool shelf is simple in structure, good looking appearance, and locking effect is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double ladder tool shelf, comprise support, tool shelf and locking mechanism, and its medium-height trestle detachable interposing connects and is positioned at double ladder top, and tool shelf is rotatably connected on support;
On described support, have straight-bar, tool shelf and straight-bar are hinged, so that tool shelf and support are rotationally connected; Described locking mechanism comprises lock dog, on straight-bar near with the hinged position of tool shelf, having a hollow pipeline section, on the tube wall of this hollow pipeline section, offer lockhole, described lock dog is in an elastic component is located at the tube chamber of hollow pipeline section, the head of lock dog is from lockhole, stretching out, and elastic component acts on the flexible direction of lock dog;
Described locking mechanism also comprises connecting rod and sliding sleeve, wherein sliding sleeve comprises housing, the part of housing is sheathed on straight-bar and is slidably matched along this straight-bar, on another part of housing, establish an elastic button and a stop collar, this stop collar carries out spacing along the straight-bar glide direction to housing, establishing the first inclined-plane along glide direction upper limit cover one side, and opposite side is established the second inclined-plane, elastic button is by depressing and can stretching into stop collar, or elastical retraction leaves stop collar;
Described connecting rod one end and tool shelf are hinged, and the housing of the other end and sliding sleeve is hinged;
When driving low sleeve at connecting rod when support rotates, tool shelf slides along straight-bar, to the hollow pipeline section place on straight-bar, lock dog was pressed on the first inclined-plane or the second inclined-plane, force in lock dog indentation lockhole, now elastic component shrinkage strain, to the stop collar place, lock dog stretches into stop collar under the effect of elastic component restoring force in, the restriction sliding sleeve slides along the continuation of straight-bar, and tool shelf is locked on support, now between tool shelf and support, has the first duty that an angle becomes expansion; Press elastic button, force elastic button to stretch into the lock dog promoted in stop collar in stop collar and make in its indentation lockhole, sliding sleeve can continue to slide along straight-bar, the relative support release of tool shelf.
Related content in technique scheme is explained as follows:
1, in such scheme, described support is the U-shaped structure, and these U-shaped two arms are described straight-bar.
2, in such scheme, described locking mechanism quantity is two, is symmetrically set in the both sides of tool shelf, all establishes a described sliding sleeve on U-shaped structure two arm straight-bars, one end of the housing of this sliding sleeve and described connecting rod is hinged, and this connecting rod other end is hinged on left side or the right side of tool shelf.
3, in such scheme, described tool shelf both sides are equipped with the card edge of stretching out outwardly, and while being parallel to the support plane, card is along being stopped by support so that tool shelf turns to, and the Limit Tool dish is rotated further, and becomes the second duty.
The utility model operating principle is: when needing the tool shelf oblique cutting on locating the double ladder of climbing, the support oblique cutting is positioned at double ladder top, and is parallel to the climbing surface of double ladder.Tool shelf drives low sleeve at connecting rod and slides along straight-bar when support rotates, to the hollow pipeline section place on straight-bar, lock dog was pressed on the first inclined-plane or the second inclined-plane, force in lock dog indentation lockhole, now elastic component shrinkage strain, to the stop collar place, lock dog stretches into stop collar under the effect of elastic component restoring force in, the restriction sliding sleeve slides along the continuation of straight-bar, tool shelf is locked on support, now between tool shelf and support, has the first duty (being generally the tool shelf level) that an angle becomes to launch, on the tool shelf of level, be convenient to place tool, facilitate staff's instrument to use.In addition, now the support of tool shelf is equivalent on the climbing surface of double ladder one side direction, to have extended, and the position that can provide grasping when the people tramples first, second rank crosspiece, leans on is avoided people's crank and turned down from ladder, therefore uses safer.Press elastic button, forcing elastic button to stretch into the lock dog promoted in stop collar in stop collar makes in its indentation lockhole, sliding sleeve can continue to slide along straight-bar, the relative support release of tool shelf, tool shelf turns to and is parallel to support plane card and is rotated further along the Limit Tool dish, become the second duty, now support can only hand be grabbed, function of leaning be used to providing.
When tool shelf is taken off from double ladder, support is extracted out from double ladder, the tool shelf that is in the second duty is folding state, is convenient to take in and transport.
For needing the horizontal applying working condition be inserted on oriented double ladder of double ladder tool shelf, the horizontal double ladder top that is inserted in of support, tool shelf turns to card while being parallel to the support plane and is rotated further (limiting downward motion) along the Limit Tool dish, become the second duty, now tool shelf is still level, but place tool on tool shelf.
Because technique scheme is used, the utility model compared with prior art has following advantages:
But 1, the utility model tool shelf be assemblied on double ladder and locking after place tool, the instrument of being convenient to the staff uses.
2, the utility model for oblique cutting the tool shelf on double ladder, its support is equivalent to the climbing surface of double ladder has been extended upward, the position that grasping can be provided, lean on when the people tramples first, second rank of double ladder crosspiece, avoid people's crank and turn down from ladder, therefore using safer.
3, locking mechanism of the present utility model is simple in structure, good looking appearance, and locking effect is good.
