Detailed description of the invention
Below with reference to the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 to Fig. 8 illustrates the railing tube connection piece embodiment of a kind of angle adjustable of the present invention, this connector includes rack body 1 and clamshell 2, rack body 1 includes the base plate 11 for connecting column tubing 3 and the side plate 12 for connecting cross beam tubing 4, clamshell 2 is fixed on column tubing 3 through base plate 11, the part stretching out clamshell 2 on side plate 12 is provided with centre bore 120, rack body 1 is hinged with crossbeam tubing 4 by the tight fixed bolt 111 through centre bore 120, can first rack body 1 and clamshell 2 be fixed on column tubing 3 during installation, again crossbeam tubing 4 is inserted between rack body 1 and clamshell 2, and pass through tight fixed bolt 111 and centre bore 120 by rack body 1 and crossbeam tubing 4 pre-connection, make crossbeam tubing 4 can rotate around this tight fixed bolt 111, angle between crossbeam tubing 4 and column tubing 3 is regulated further according to stair lift angle, its fastening is positioned after putting in place by adjustment again through tight fixed bolt 111, simple to operate, install easy to adjust, accurate positioning, meanwhile, the completely available sheet metal of rack body 1 being made up of base plate 11 and side plate 12 in the present invention bends shaping, and its bonding strength has compared to existing plastic fittings and significantly promotes.
In the present embodiment, side plate about 12 both sides are respectively equipped be round dot with the center of circle of described centre bore 120 first rotate segmental arc 125 and second and rotate segmental arc 126, the center of circle of centre bore 120 is positioned at clamshell 2 port institute planar, first midpoint rotating segmental arc 125, the center of circle of the second midpoint rotating segmental arc 126 and centre bore 120 is located along the same line, the structure on side plate about 12 both sides can ensure that crossbeam tubing 4 has bigger angle of regulation range, when regulating angle between crossbeam tubing and column tubing, crossbeam pipe material inner wall and first rotates segmental arc and the second rotation segmental arc keeps in touch, therefore crossbeam tubing be positioned at optional position all can be subject to the first rotation segmental arc and second rotate segmental arc support, the spacing of crossbeam outer pipe wall and clamshell port edge is limited only by the impact of crossbeam tube wall thickness and rotational angle simultaneously, and tube wall thickness is generally 1-2MM, therefore the impact of this gap is negligible, thus realizing " slitless connection " of crossbeam outer pipe wall and clamshell, thus ensureing the overall aesthetics of stair railing.
In the present embodiment, the top of the side plate 12 of rack body 1 also includes first spacing section 121 and second spacing section 122 that is divided into the first rotation segmental arc 125 both sides, the 3rd spacing section 123 and the 4th spacing section 124 that also includes below being divided into the second rotation segmental arc 126 both sides of side plate 12, as shown in Figure 4, first spacing section 121 and the 3rd spacing section 123 all connects with base plate 11, first spacing section 121 spacing with the 4th sections 124 parallel, second spacing section 122 spacing with the 3rd sections 123 parallel, facilitates rotating around rack body 1 of crossbeam tubing 4. Crossbeam tubing 4 inwall being projected as on cross section is square, crossbeam tubing 4 inwall width is H, first spacing section of distance between 121 and the 4th spacing section 124 is H, second spacing section of distance between 122 and the 3rd spacing section 123 is also H, when crossbeam tubing 4 turns to upper and lower two limit positions, crossbeam tubing 4 inwall can be subject to a pair support of spacing section simultaneously, improves support strength when crossbeam tubing 4 is in extreme position by connector.In the present invention, the radius of the first radius and the second rotation segmental arc rotating segmental arc is H/2, ensure when crossbeam tubing 4 is in non-extreme position, all the time two-point contact is kept with the side plate 12 of rack body 1, thus improving support strength when crossbeam tubing 4 is in non-extreme position by connector.
In the present embodiment, the angular bisector between clamshell 2 port place plane and first spacing section 121, the 3rd spacing section 123 is vertically arranged, and rotates upwardly and downwardly around rack body 1 for crossbeam tubing 4 and reserves suitable space, facilitates crossbeam tubing 4 to rotate within the specific limits.
In the present embodiment, the angle of first spacing section of angular bisector of angle between 121 and the 3rd spacing section 123 and base plate 11 is ��, first spacing section 121, second spacing section 122, the 3rd spacing section 123, the 4th spacing section 124 is �� with the angle of above-mentioned angular bisector, by arranging the size of angle �� and ��, two pieces railing tube can be made when connecting, to have certain angle of regulation range and (to set rotation adjusting angle as ��, then alpha-beta�ܦ���alpha+beta), the connector making the present invention goes for the multiple mounting location that stair lift angle is different, adaptable. In the present embodiment, ��=55 ��, ��=10 ��. As shown in Fig. 5 to Fig. 8, when the upper inwall of crossbeam tubing 4 and first spacing section 121 contact, lower inwall contacts with the 4th spacing section 124 simultaneously, and now the angle of crossbeam tubing 4 and column tubing 3 is alpha+beta=65 ��, as shown in Figure 6. When upper inwall and second spacing section 122 contact of crossbeam tubing 4, lower inwall and the 3rd spacing section 123 contact simultaneously, now crossbeam tubing 4 is alpha-beta=45 �� with the angle of column tubing 5, as shown in Figure 7, it is seen that the connector in the present embodiment can be used for the stair railing that lift angle is 45 �㡫65 �� and installs. Fig. 8 then illustrates when the inwall up and down of crossbeam tubing 4 does not contact with any spacing section of rack body 1, crossbeam tubing 4 inserts the state of connector with nonspecific angle (namely 45 �� < �� < 65 ��), in this state, the inwall up and down of crossbeam tubing 4 contacts with first rotation segmental arc the 125, second rotation segmental arc 126 respectively.
In the present embodiment, rack body 1 is connected with crossbeam tubing 4 by the tight fixed bolt 111 through centre bore 120, base plate 11 both sides are provided with pair of side plates 12, centre bore 120 on one side plate 12 is the screwed hole coordinated with tight fixed bolt 111, tighten Shi Qike at tight fixed bolt 111 biside plate 12 appropriateness of rack body 1 to be strutted, the side plate 12 of driving arm body 1 realizes swelling with crossbeam tubing 4 inwall and is connected, it is ensured that connective stability; Centre bore 120 on another part side plate 12 is the pilot hole to location, tight fixed bolt 111 end, and the tail end of tight fixed bolt 111 props up pilot hole, and pilot hole can avoid tight fixed bolt 111 to offset when pushing against rack body 1 side plate 12, it is ensured that swelling effect.
