Detailed description of the invention
Below for scaffold connecting portion, describe embodiment of the present utility model by reference to the accompanying drawings in detail.
As shown in Figure 1, the structure of the present embodiment comprises transverse tube 1, vertical tube 7 and connects the linkage of transverse tube 1 and vertical tube 7, linkage comprises the cage plate 8 with centre bore 801 and two trepanning 802 and the hanging hook assembly with housing 4, hook 6, wedge-shaped bolt 5 and helical spring 3, housing about 4 both ends open, one end and transverse tube 1 end winding support, its upper side wall and lower wall are respectively equipped with a through hole 401; Hook 6 is located in housing 4, be made up of two blocks of side plates 603 and the backboard 601 being clamped in two pieces of side plate 603 tail ends that is fixed, side plate 603 front end is provided with stretches out downwards and the prominent hook portion 604 can inserted in the two trepanning 802 of cage plate, on backboard 601, the medial surface 605 of close prominent hook portion 604 is the inclined-plane that lower end tilts to prominent hook portion 604, is vertical plane with the lateral surface 602 that this inclined-plane is opposing; Wedge-shaped bolt 5 is located between the biside plate of hook 6, and top and bottom are each passed through the through hole 401 of housing upper side wall and lower wall, and wedge-shaped bolt 5 leading flank 502 is vertical plane, and trailing flank 501 is the inclined-plane of fitting with hook backboard 601 medial surface; The inside at transverse tube two ends is provided with baffle plate; Helical spring is located in housing, and two ends are coupling hook backboard 601 and vertical tube interior panelling 2 respectively.
In the present embodiment, housing 4 is provided with near the front-rear side walls of vertical tube 7 one end can holds cage plate 8 and stretch into draw-in groove 402 in housing.The lower end of wedge-shaped bolt 5 leading flank is provided with the prominent hook 503 stretched out forward.Cage plate 8 is provided with the many groups of two trepannings 802 around the distribution of centre bore 801 even circumferential.
The operating principle of the present embodiment is as follows:
After assembling as shown in Figure 1, knock wedge-shaped bolt downwards, the trailing flank of wedge-shaped bolt produces interaction frictional force with the medial surface hanging component backboard, thus to hanging the thrust of component generation to transverse tube side, hang component to move to transverse tube, thus the two trepannings on the prominent hook portion of hook side plate front end and cage plate are strained.
During dismounting, upwards knock wedge-shaped bolt, wedge-shaped bolt is moved upward, due to helical spring elastic force effect, extension component is made to produce the thrust to vertical tube side to wedge-shaped bolt, hang component to vertical tube one lateral movement, the two trepannings on the hook prominent hook portion of side plate front end and cage plate unclamp, and hanging hook assembly can be separated with cage plate simultaneously.
Below related description is done to said structure:
1, compared to semielliptic spring, helical spring longer service life, stability is higher, therefore adopts helical spring to replace semielliptic spring in the present embodiment.
2, the backboard trailing flank hanging component in the present embodiment is vertical plane, matches with helical spring, reduces the component straight up that wedge-shaped bolt is subject to, thus effectively prevents coming off of wedge-shaped bolt.
3, housing being installed helical spring side is opening, to increase helical spring installing space, and can either the cost-saving stability that can improve again linkage.
