Description

Height-adjustable hanger

Technical field

The utility model relates to a kind of hanger, especially a kind of hanger that can vertically open or draw in.

Background technique

Present range hood for kitchen use is fixed installation, and its height can not be regulated, and in use, range hood has been installed low and met and discussed easily, and the effect of installing lampblack suction exhausting high is relatively poor.Devices such as the light of rise-fall type clothes hanger, specific use, wall hanging TV set also need be regulated its setting height(from bottom) sometimes in addition.

Summary of the invention

The purpose of the utility model is for aforementioned device a kind of height-adjustable hanger to be provided.

Adopt following technical proposals: a kind of height-adjustable hanger, to form by a group or more support arm, every group of support arm that has two X-shapeds to intersect, center lock pin pass the center hole of support arm with its movable connection.

The upper end of hanger is a upper beam, and two upper sliding sleeves are set in the right and left of upper beam, and sliding sleeve can horizontally slip on crossbeam.The lower end of hanger is a bottom end rail, and two low sleeves are set in the right and left of bottom end rail, and the lower limb of bottom end rail all is arranged to the identical serrated edge of modulus with the contact position in the low sleeve, and when two serrated edge engagements, sliding sleeve promptly can not slide; When bottom end rail moves up, when two serrated edges broke away from, sliding sleeve can horizontally slip on crossbeam.

When hanger had only one group of support arm, the upper end of every group of two X-shapeds intersection and the movable support arm that connects connected with two upper sliding sleeves are movable respectively, and the lower end of support arm connects with two low sleeves activities respectively.

When hanger has two groups or more support arm; Topmost the upper end of one group of support arm connects with two upper sliding sleeves are movable respectively; The lower end of bottom one group of support arm connects with two low sleeves are movable respectively, and all the other are that the lower end of last one group of support arm connects with the upper end activity that next organizes support arm respectively.The group number of support arm is many more, and the amplitude of accommodation of hanger height is big more.

Upper beam is fixed on the wall or inner top surface of building.The right ends of upper beam respectively has the erection opening of a hanger, is respectively installed with pressure spring on the crossbeam between both sides upper sliding sleeve and the two ends mounting hole; When load is heavier, can increase the erection opening of a hanger at the middle part of upper beam.

Load is installed on the bottom end rail, hole or screw that the right ends of bottom end rail respectively has an installation load to use; When load is heavier, can increase a hole or the screw that installation load is used at the middle part of bottom end rail.

The middle part of upper beam is installed with a chute vertically downward; The rear end of center lock pin is provided with a flange, and more than the width 0.01mm of the external diameter of flange less than chute, this flange places in the chute and can slide up and down, to guarantee that hanger opens or when drawing in, support arm can not offset to one side.More than the long 0.01mm of lower dead center of the lower end of chute than center lock pin flange, preferably 10mm～20mm deviates from chute to prevent center lock pin flange.

The utility model is simple in structure, and is with low cost, of many uses, and the amplitude of accommodation is big, easy to use and reliable.

Embodiment

Specifically describe below in conjunction with accompanying drawing: Fig. 1, shown in Figure 2 for having only the hanging rack structure of one group of support arm.Among the figure, the upper end of hanger is the right and left that 4, two upper sliding sleeves 3 of upper beam are set in upper beam 4, and respectively there is the erection opening 1 of a hanger at the two ends of upper beam 4.The lower end of hanger is the right and left that 7, two low sleeves 9 of bottom end rail are set in bottom end rail 7, and the two ends of bottom end rail 7 are provided with load erection opening 8.6 one-tenth X-shapeds of two support arms intersect, and center lock pin 12 passes the center hole of support arm 6 with its movable connection.The upper end of support arm 6 connects with 3 activities of two upper sliding sleeves respectively, and the lower end connects with 9 activities of two low sleeves respectively.Pressure spring 2 is set on the upper sliding sleeve 3 and the upper beam 4 between the hanger mounting hole 1 on both sides, and when passing hanger mounting hole 1 with mounting screw with after the hanger fixed installation, then conflict respectively on upper sliding sleeve 3 and mounting screw in the two ends of pressure spring 2.The middle part of upper beam 4 is installed with a chute 5 vertically downward, and when hanger went up and down, the flange 14 of center lock pin 12 rear ends slided up and down (as shown in Figure 5) all the time in chute 5.Bottom end

rail tooth limit

10 and 13 engagements (like Fig. 3, shown in Figure 4) of low sleeve internal tooth.Lock pin 11 interts respectively at each movable joint place of upper and lower end of upper sliding sleeve 3 or low sleeve 9 and support arm 6.

During the height of regulating load downwards, upwards lift load with hand earlier, bottom end rail 7 is unsettled; Bottom end rail tooth limit 10 breaks away from low sleeve internal tooth 13; At this moment the tension force of the right and left pressure spring 2 respectively with about two upper sliding sleeves 3 promote to the direction of middle chute 5, the upper and lower end of support arm 6 and upper sliding sleeve 3, low sleeve 9 draw in to the centre simultaneously, upper beam 4 increases with bottom end rail 7 spacings; Bottom end rail 7 descends, and at this moment using hand rest load also should be along with synchronous decline.When the needed height, put down load, bottom end rail 7 falls, bottom end

rail tooth limit

10 and 13 engagements of low sleeve internal tooth, the shape of hanger and highly promptly being fixed.

Upwards during the height of regulating load; Firmly upwards lift load; Bottom end rail tooth limit 10 breaks away from low sleeve internal tooth 13; The bottom end rail 7 upwards lower end and the low sleeve 9 of roof pressure support arm 6 opens to the two ends of bottom end rail 7, and the upper end of support arm 6 and upper sliding sleeve 3 open to the two ends of upper beam 4 simultaneously, and spring 2 is compressed.Upper beam 4 dwindles with bottom end rail 7 spacings, and bottom end rail 7 rises.When the needed height, put down load, bottom end rail 7 falls, bottom end

rail tooth limit

10 and 13 engagements of low sleeve internal tooth, the shape of hanger and being fixed highly again.

The hanging rack structure similar with the hanging rack structure that has only one group of support arm (as shown in Figure 6) that two groups or more support arm is arranged.
