Abstract
A double-shaft lever-type castor for doors and windows comprises an outer shell, a support, sliding wheels, a wheel carrier and an adjusting bolt, wherein the free ends of the wheel carrier are connected with the sliding wheels, the outer shell is provided with a fixing shaft hole and a plurality of mounting holes, the support is clamped and sleeved into the inner cavity of the outer shell, one end of the support is connected to the fixing shaft hole through a fixing shaft, the adjusting bolt sequentially penetrates adjusting holes on the outer shell and the support and then is connected with a nut, the outer shell is also provided with a sliding shaft hole, and the free ends of the support, or a hinged end of the wheel carrier and the free ends of the support, are respectively connected to the sliding shaft hole through a sliding shaft, so as to form a single wheel or a double wheel structure. According to the technical scheme, a stable three-point strength bearing structure is formed by the outer shell and the support, connecting strength of the support and the outer shell is greatly enhanced, the loading bearing capability of the castor is raised, and the problems that the conventional castor is poor in load bearing capability because the connecting strength of the support and the outer shell is inadequate and leaf frames are easy to shake inwards and outwards during sliding when the conventional castor is used are solved.
Description
Technical field:
The utility model relates to the castor field, relates in particular to twin shaft lever door and window castor.
Background technology:
Existing lever door and window castor, its structure is that chuck has support in the inner chamber of shell, support is connected with the shell single shaft, having bolt to pass shell is connected with nut with support, pulley (single-wheel) or wheel carrier (three axis holes are the support that isoceles triangle distributes, and two base angle axis holes are used for installing pulley) are coupling at the free end of support, and swivel bolt can make the free end lifting of support, in order to obtain tangible lifting effect when adjusting, the hinge point on the support need be away from free end; From said structure as can be known, owing to have only only one hinge point between support and shell, and the free end of the hinge point on the support on it again away from, although also making, the bolt after screwing added a tie point between support and shell, but do not form the rock-steady structure of 3 loads all the time, so there is the not enough problem of heavy burden ability in actual use; Because under the bigger situation of bearing a heavy burden, slide the fan frame, the free end of above-mentioned support rocks can be more serious, rocked for a long time, many, to cause the adjustment bolt looseness, further aggravate shaking degree, when serious even produce inclined to one side limit and obscission, weather strip hit press and wearing and tearing, reduced the sealing performance of fan frame.
Yet, in order to satisfy people slide door or window there is the expectation of better sealing performance, existing fan frame adopts two glass structures substantially, and its weight has been significantly to increase, this shows, and the above-mentioned castor of prior art has been difficult to satisfy normal instructions for use.
The utility model content:
In order to solve above-mentioned deficiency, the utility model is to provide a kind of twin shaft lever door and window castor, compared with prior art, the twin shaft hole is set on the shell of this castor is twin shaft with support and is connected, and has extremely strong heavy burden ability.
Its technical scheme is as follows:
A kind of twin shaft lever door and window castor, contain shell, support, pulley or wheel carrier, adjust bolt, two free ends of wheel carrier are connected with pulley, described shell is provided with fixed shaft hole and some installing holes, described support chuck hinged end in the inner chamber of shell be fixed the axle be connected on the fixed shaft hole, adjusting the screw bolt passes shell is connected with adjustment Kong Houyu nut on the support, also be provided with the slip axis hole on the described shell, have sliding axle that the free end of support or the free end of support and the hinged end of wheel carrier are connected on the slip axis hole;
Rotate around fixed axis in order to make sliding axle follow support, described sliding eye is rectangular arcuate socket, and its circular arc is the fixing hole concentric arc;
When above-mentioned sliding axle connects the free end of support, be connected with pulley on another free end on the support, be the single-sheaved block structure;
Above-mentioned sliding axle is many pulley structures when connecting wheel carrier;
Its principle is to adjust bolt pulling nut by rotation, and support is rotated around fixed axis, raises simultaneously or descends thereby make the pulley that is connected on the support free end or wheel carrier follow sliding axle, has reached the purpose that can adjust fan frame height when using; Structurally owing to have bolt, fixed axis, three tie points of sliding axle between shell and support, form the rock-steady structure of 3 loads, strengthened the bonding strength of support and shell greatly, reached the strong purpose of design of described castor heavy burden ability.
The beneficial effects of the utility model are: owing to be connected with twin shaft between the shell of described castor and support, have bolt, fixed axis, three tie points of sliding axle, constituted the rock-steady structure of 3 loads, thereby strengthened the bonding strength of support and shell greatly, improved the heavy burden ability of castor, the bonding strength that has solved prior art medium-height trestle and shell is not enough, and the heavy burden ability causes the technical problem that the fan frame rocks inside and outside easily in slip.

The specific embodiment:
Be further elaborated below in conjunction with the structure of accompanying drawing to twin shaft lever door and window castor described in the utility model.
The described twin shaft lever of present embodiment door and window castor is many wheel constructions, with reference to figure 1,2, as shown in these figures, described lever door and window castor, contain shell 1, support 2, wheel carrier 3, adjust bolt 5, two free ends of wheel carrier 3 are connected with pulley 4, described shell 1 is provided with fixed shaft hole 10 and some installing holes 12, described support 2 chucks are in the inner chamber of shell 1, the hinged end axle that is fixed 7 is connected on the fixed shaft hole 10, adjust bolt 5 in the side near fixed shaft hole 10, pass successively and adjust 13 backs, hole on shell 1 and the support 2 and be connected with nut 6, also be provided with slip axis hole 11 on the described shell, have sliding axle 8 that the hinged end of wheel carrier 3 is connected on the slip axis hole 11.
The assembling process of present embodiment is as follows:
As shown in Figure 2, pulley 4 usefulness wheel shafts 9 are connected in the axis hole 14 on 3 liang of free ends of wheel carrier, wheel carrier 3 is enclosed within the inner chamber of shell 1 after being enclosed within the support 2 together, and sliding axle 8 is connected the free end of support 2, the hinged end of wheel carrier 3 on the shell 1 after passing sliding eye 11 on the shell, the axis hole 14 on the support, the axis hole 15 on the wheel carrier; The fixed end that fixed axis 7 passes behind fixing hole 10 on the shell, the axis hole 15 on the support support 2 is connected on the shell 1; Adjusting bolt 5 passes shell 1 successively and is connected with nut 6 with 13 backs, adjustment hole on the support 2.
With reference to figure 3, the described twin shaft lever of present embodiment door and window castor is the single-wheel structure, as shown in the figure, the structure of this embodiment is identical with the structure of embodiment 1 substantially, difference only is how a free end 24 that connects pulley 4 has been set on the support 2, the free end that sliding axle 8 passes behind slip axis hole 11 on the shell, the axis hole 14 on the support support 2 is connected on the shell 1, and other something in common repeats no more.
