Specific embodiment
The embodiment of the present invention is described in further detail below in conjunction with attached drawing.
Shown in Figure 1, the embodiment of the present invention provides a kind of plastic guide rail lifter, including guide rail 1, guide wheel bracket 3 With guide part 4, wherein the guide rail 1 is equipped with directive wheel 2, and drag-line 5 is slidably equipped on the directive wheel 2, and the cunning of drag-line 5 is set Between the directive wheel 2, lifting is realized by sliding;The guide wheel bracket 3 is for the directive wheel 2 to be fixed on On the guide rail 1, the side of the guide wheel bracket 3 is equipped with fixing piece 30, and the fixing piece 30 is equipped with first through hole, described Guide part 4 is removably at least partially disposed in the first through hole, and the guide part 4 and fixing piece 30 are provided commonly for will be described In the guidance to the directive wheel 2 of drag-line 5.Here guide wheel bracket 3 uses metal material, and guide part 4 uses plastic material.
Shown in Figure 2, the guide part 4 includes connected insertion piece 40 and supporting piece 41, and the insertion piece 40 is set to The top of the supporting piece 41, and the cross sectional dimensions of the insertion piece 40 is less than the supporting piece 41.40 He of insertion piece The second through-hole is equipped in supporting piece 41, and two second through-holes composition that is connected wears channel, when the insertion piece 40 When being inserted in the first through hole, the be connected channel that wears of composition of second through-hole connect phase with second through-hole It is logical, and the one end that is connected with insertion piece 40 of the supporting piece 41 is held in the end of the fixing piece 30, the fixing piece at this time The 30 fixed guide parts 4.The effect of the guide part 4 and fixing piece 30 is led to when the drag-line 5 sequentially passes through described second Around when being set on the directive wheel 2 behind hole and first through hole, the insertion piece 40 of the guide part 4 is inserted in the fixing piece 30 In first through hole, the guide part 4 and fixing piece 30 provide support and guiding channel jointly for the drag-line 5.Simultaneously as institute It states insertion piece 40 to be inserted in the first through hole, therefore the drag-line 5 can effectively be avoided to contact with the inner wall of fixing piece 30, To prevent the drag-line 5 to be worn during sliding lifting.
Specifically, the fixing piece 30 is the hollow cylindrical structure that side has opening, the same of manufacture craft can be simplified Time about cost of manufacture, the size of the opening is less than the diameter of the drag-line 5, to prevent the drag-line 5 in the process of sliding In deviate from out of the fixing piece 30 first passage, and influence the lifting of lifting rail device.Further, for convenience by institute It states insertion piece 40 to be inserted in the fixing piece 30, therefore, the fixing piece 30 at least partly stretches out in outside the guide rail 1, side Just operator carries out plugging operation, and design is reasonable.The length of the fixing piece 30 is 6-8mm, the internal diameter of the fixing piece 30 For 6.5mm, outer diameter 9.5mm.The guide wheel bracket 3 and fixing piece 30 are an integral molding structure.
Further, the angle designed from structure, the insertion piece 40 and supporting piece 41 are hollow cylinder knot Structure, the internal diameter of the insertion piece 40 i.e. diameter of the second through-hole is greater than the diameter of the drag-line 5, but is less than the first through hole Diameter, the outer diameter of the supporting piece 41 are greater than the outer diameter of the fixing piece 30.The insertion piece 40 and supporting piece 41 are integrated into Type structure.
Further, the guide wheel bracket 3 further includes the first chimb 31 and the second chimb 32, first chimb 31 In on the top side of the guide wheel bracket 3, second chimb 32 is located in the bottom side of the guide wheel bracket 3, The rotation of directive wheel 2 is embedded between first chimb 31 and the second chimb 32, and first chimb 31 is used for anti-on-slip Rope abjection on the directive wheel 2, second chimb 32 are used to increase the intensity of the guide wheel bracket 3, make it It is unlikely to deform or damages, guarantee structural stability.
Further, one is additionally provided on the guide wheel bracket 3 for the directive wheel 2 to be fixed on consolidating on guide rail 1 Determine hole 33,33 diameter of fixation hole is 8mm or so, positioned at the center of the guide wheel bracket 3, by bolt by the guiding Wheel 2 is fixed on the guide rail 1.One is additionally provided on the guide wheel bracket 3 for the guide wheel bracket 3 to be fixed on guide rail The diameter of location hole 34 on 1, the location hole 34 is less than the fixation hole 33, is fixed on guide wheel bracket 3 by bolt On guide rail 1.
The action principle of the lifting rail device are as follows:
The lateral slot of guidance drag-line is provided on the pure resin glass lifter of traditional cable pulley type, lateral slot has certain Gradient, however since in production, the direction of demoulding is different from the stripping direction of guide rail, therefore, cause production process multiple Miscellaneous, Production Time is longer and the cost is relatively high.The lifting rail device, which passes through, is arranged the fixing piece 30 and guide part 4, when The drag-line 5 sequentially passes through after second through-hole and first through hole around when being set on the directive wheel 2, the guide part 4 Insertion piece 40 is inserted in the first through hole of the fixing piece 30, and the guide part 4 and fixing piece 30 can be the drag-line 5 jointly Support and guiding channel are provided, therefore, the guide rail 1 can save the step of making lateral slot in production, simplify described The manufacture craft of guide rail 1 reduces cost of manufacture, and design is reasonable, of simple structure and strong practicability.
The present invention is not only limited to above-mentioned preferred forms, anyone can show that other are each under the inspiration of the present invention The product of kind form, however, make any variation in its shape or structure, it is all with identical or similar with the present invention Technical solution, within its protection scope.
