Embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1, a kind of support of the present invention, comprise upper pright stanchion 1, upper pright stanchion 1 upper end bracing frame 2, be set in the lower vertical rod 3 on upper pright stanchion 1 outer wall and be arranged on the tripod 4 of lower vertical rod 3 lower end, described upper pright stanchion 1 and lower vertical rod 3 are square tube, and lower vertical rod 3 outer wall is provided with upper pright stanchion 1 relative to the securing upper locking device 5 of lower vertical rod 3.
Introduce a kind of structure below simple, lock firm upper locking device.As shown in Figure 2, described upper locking device 5 is by the top base 6 being fixed on end, lower vertical rod 3 upper end, be arranged on the upper blocking seat 7 in top base 6 and be with the upper knob 8 of screw rod to form, the lower end of upper pright stanchion 1 stretches in lower vertical rod 3 from top base 6 upper end, the cross section of upper blocking seat 7 takes the shape of the letter U, the screw rod end of upper knob 8 to stretch in top base 6 and through upper blocking seat 7 while be threaded with another side, upper pright stanchion 1 is positioned at the space that the screw rod of upper knob 8 and upper blocking seat 7 enclose, like this when screwing and outwarding winding upper blocking seat 7, the both sides of upper blocking seat 7 can be made to shrink and open, thus realize the object clamping and unclamp upper pright stanchion 1.
For the ease of the fixing and adjustment bottom screen, adopt the lower locking device of following structure.As shown in Figure 3, described lower vertical rod 3 is also arranged with the lower locking device 9 for installing curtain, lower locking device 9 comprises and being set in lower vertical rod 3 and the bottom base 10 that can move up and down along lower vertical rod 3, the lower deck 11 be arranged in bottom base 10, the band lower knob 12 of screw rod and C shape handle 13, the cross section of lower deck 10 takes the shape of the letter U, the screw rod end of lower knob 12 to stretch in bottom base 10 and through lower deck 10 while be threaded with another side, one end of C shape handle 13 is fixedly connected with bottom base 10, and the other end is set in lower vertical rod 3.
As shown in Figure 4, support frame as described above 2 to be connected with channel-section steel 15 by L shape support bar 14 and to form, the lower end of the vertical straight line segment of support bar 14 is fixedly connected with the upper end of upper pright stanchion 1, the horizontal linear section of support bar 14 is arranged these straight-line segment two ends through and the groove 16 of opening upwards, one end of channel-section steel 15 is positioned at the groove 16 of support bar 14 and hinged with support bar 14, also upwards, channel-section steel 15 can be embedded in the groove of support bar 14 after overturning the opening of channel-section steel 15.Like this when support does not use time, can rotate in the groove 16 of channel-section steel 15 to support bar 14, thus reduce the space shared by bracing frame 2.As figure, on two edges of the notch of described support bar 14 horizontal linear section and on notch two edge of channel-section steel 15, be respectively arranged with the tooth mouth 17 of row's correspondence.
Described tripod 4 is made up of three stocks, 18, three quarter butts 19 and the sliding sleeve moving up and down 20 be set in lower vertical rod 3, one end of stock 18 is hinged with sliding sleeve 20 respectively, one end of quarter butt 19 is hinged with the lower end of lower vertical rod 3 respectively, the other end is hinged respectively with the middle part of corresponding stock 18, the lower end of stock 18 is enclosed with one deck rubber respectively, the lower end of stock 18 is made to have good adherence properties like this, well can ensure that tripod 4 fixes on the ground after opening, and sliding sleeve 20 can not be caused to move up and down.
Principle of work of the present invention is: first open tripod 4, then to outward winding upper knob 8, the distance on upper blocking seat 7 both sides under the constraint without upper knob 8 increases, thus make upper pright stanchion 1 depart from upper blocking seat 7, upper pright stanchion 1 just can move up and down, and upper pright stanchion 1 can be transferred to suitable height by such operating personnel as required, and then screws upper knob 8, upper blocking seat 7 both sides are tightened up, thus upper pright stanchion 1 is fixed.Then as required the fulcrum outside screen shell is stuck in the tooth mouth 17 of support bar 14, if channel-section steel 15 can produce by distance not from support bar 14, then fulcrum is stuck in the tooth mouth 17 of channel-section steel 15.If regulate the position of lower locking device, can unclamp lower knob 12, its method of operating is identical with the method for operating of upper locking device 5, just repeats no more at this.Just the lower end of fixing screen can be fixed on lower locking device after lower locking device has regulated, realize the fixing of screen.Utilize above-mentioned upper locking device, fixing upper pright stanchion 1 that can be very convenient, firm and the relative position of lower vertical rod 3, lower vertical rod 3 arranges lower locking device, is convenient to being affiliated to of screen.
