Description

Simple screen framework connecting elements

Technical field

The utility model relates to a kind of fastening or fixed component, relates more specifically to a kind of member that is used for connecting between the Frame of screen.

Background technology

Present commercially available all kinds of Frame of screen jockeys, majority are that two frameworks carry out the screw locking by a brace, and this kind connects shortcoming and be: it is poor to connect stable type between the framework, rock easily and install loaded down with trivial details, inconvenient maintenance, what have can't repeat assembling, causes waste.

Summary of the invention

The purpose of this utility model provides a kind of simple and easy quick and Frame of screen syndeton that stability is high, and the utilization by one group of pin fully closely connects two frameworks.

The purpose of this utility model is achieved in that and comprises first upright of frame, second upright of frame and one group of pin, said first upright of frame is one to have the cross section moulding can extend the Al squeezing material of total length, there is a convex shape near closed hollow ring its inside, outside the near closed hollow ring left side, extend the L shaped convex tendon of two symmetries, be provided with a upper end convex tendon in outside, die cavity right side, be provided with a lower end groove in lower end, die cavity right side, be equipped with column top circular hole and the column bottom circular aperture that runs through respectively in the nearly upper end of section bar and the end face centre of nearly bottom.Second upright of frame is the symmetrical part of the first upright of frame Rotate 180 °.Pin has oblate column cap, middle cylinder, thin cylinder and head chamfering in proper order.First upright of frame and second upright of frame upper end convex tendon separately inserts in the other side's the lower end groove, and pin inserts column top circular hole and the swelling of column bottom circular aperture respectively between the convex tendon of the upper end of two upright of frame and to connect two upright of frame be one.

The beneficial effects of the utility model are structural stability height, simple and convenient is installed, and the utilization by one group of pin fully closely connects two frameworks, and it is fixed to need not screw pins, has improved installation rate, is the novel structure during a kind of Frame of screen connects.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described, sees also each accompanying drawing, the said a kind of Simple screen framework connecting elements of the utility model comprises first upright of frame 1, second upright of frame 2 and one group of pin 3.Described first upright of frame 1 is one to have the cross section moulding can extend the Al squeezing material of total length, and its average thickness is 1.5 millimeters, and there is a near closed hollow ring 101 inside, " protruding " font of the similar inverse time half-twist of the moulding of die cavity.Extend the L shaped convex tendon 102 of two symmetries outside near closed hollow ring left side 103, be provided with a upper end convex tendon 105 in die cavity right side 104 outer upper ends, the similar letter of its hollow space moulding " T " is provided with a lower end groove 106 in its lower end, right side; Circular hole in that the upper end and the bottom of section bar are beaten diameter 4 respectively is called column top circular hole 107 and column bottom circular aperture 108, and the sectional position of circular hole is in the centre of outer face, a near closed hollow ring left side, and circular hole runs through left and right sides end face.The quantity of circular hole is decided according to the length of section bar, and one meter with interior need two holes up and down, and one meter with upper pillar stand, and the every increase of length can increase by a circular hole to increase stability for 200 millimeters.Second upright of frame 2 is for there to be the cross section moulding can extend the Al squeezing material of total length, its cross section is shaped to first upright of frame, the 1 cross section symmetrical part of Rotate 180 ° in the direction of the clock, and coming first upright of frame 1 and second upright of frame 2 therefrom is the Al squeezing material of same cross section moulding.The feature of pin 3 is made up of three parts, 50 millimeters of total lengths, and plating zinc on surface is blunt white.First is the oblate column cap 301 of 3 millimeters of 12 millimeters thickness of a diameter; Second portion is the middle cylinder 302 of 12 millimeters of diameter 7 mm lengths, and it forms a step in oblate column cap; Third part is the thin cylinder 303 of 35 millimeters of diameter 3.6 mm lengths, makes 3 millimeters chamferings at the head of thin cylinder, forms head chamfering 304, and wherein thin body diameter can be made 0.2 millimeter last tolerance, and itself and middle cylinder also form a step.

When two frameworks connected, in the horizontal direction with first upright of frame and the mutual snapping of second upright of frame, the upper end convex tendon that is about to separately inserted in the other side's the lower end groove, is implemented in horizontal direction and can not moves separately.Then pin is inserted in the circular hole at column top, beat in the horizontal direction with iron hammer, because of the thin cylinder head of pin has been done chamfering, the pin along continuous straight runs enters between the upper end convex tendon of two upright of frame, when 302 end faces of cylinder in the pin touch the outer face of column near closed hollow ring, stop to knock.Because of the thin body diameter of pin greater than about 0.2 to 0.4 millimeter of the distance of two columns upper end convex tendon, the upper end convex tendon of two upright of frame moves in the vertical direction respectively, tightly be pressed into the inwall of lower end groove, therefore the thin cylinder of pin fully swelling in two upright of frame, two upright of frame can not be moved in vertical direction.In like manner insert pin, make two upright of frame closely connect one, closely cooperate thereby drive two frameworks in the bottom of two columns.When strut length during less than 1 meter, need only insert two pins at top and bottom, every increase above 1 meter can be inserted a pin again with the increase connection stability for 200 millimeters.So far, two frameworks rely on pin to connect and have been completely fixed one.The utility model structural stability height is installed simple and conveniently, has improved installation rate, is the novel structure device during Frame of screen connects.
