Description

A kind of overlapped furniture metallic square tube frame stull and stull right angle connector

Technical field

The utility model relates to metal tubular product right angle overlapping technology field more particularly to a kind of furniture metallic square tube frames Overlapped stull and stull right angle connector.

Background technique

As shown in fig. 6, be a kind of furniture metallic square tube frame stull described in the utility model with stull right angle overlapped Schematic diagram, as shown in Figure 1, being that overlapped a kind of furniture metallic square tube frame stull described in the utility model and stull right angle even Fitting, the connector include an attachment base 1 and a tensioner component 2, and the attachment base 1 is equipped with connector 11, the connector 11 are equipped with one for accommodating the empty slot 121 of tensioner component 2；There are two tensioner screw holes 22 on the tensioner component 2.

The structure of the prior art is: the connector 11 is solid, i.e. tensioner component 2 and 121 integrator of empty slot, in institute It states connector 11 and is equipped with 1~2 tensioner screw hole 22, be pre-loaded into interior hexagonal tensioner screw 23, interior hexagonal in tensioner screw hole 22 The length of tensioner screw 23 is equal to the length of tensioner screw hole 22；In use, first by the end of the connector 11 insertion metal side tube 3 In mouth 31, the position of the end corresponding joints tensioner screw 23 of metal side tube 3 is equipped with the fabrication hole that can be inserted into allen wrench 5 32, the diameter of the fabrication hole 32 is slightly larger than the circumscribed circle diameter of the hexagonal section of allen wrench 5, and is less than interior hexagonal and rises The maximum outside diameter of tight screw 23；After the connector 11 is inserted into metal side tube port 31, by the fabrication hole 32 of metal side tube, with interior Die nut 5 rotates interior hexagonal tensioner screw 23, and the interior hexagonal tensioner screw 23 will be exited from tensioner screw hole 22, top Continue in reverse rotation in the inner wall of metal side tube since the outer diameter of interior hexagonal tensioner screw 23 is greater than the diameter of fabrication hole 32 When hexagonal tensioner screw 23, the tail portion of the interior hexagonal tensioner screw 23 will hold out against the inner wall of metal side tube 3, make metal side tube 3 are fastenedly connected with the formation of connector 11, when attachment base 1 is fixedly mounted on the side wall of another metal side tube 4 with bolt, metal The right angle that square tube 3 and metal side tube 4 just form fastening overlaps.

The defect of this prior art construction has two o'clock: first is that the end of interior hexagonal tensioner screw 23 and metal side tube inner wall The area of contact is too small, and it is unreliable to fasten；Second is that firmly screwing interior hexagonal tensioner screw 23 to improve the reliability of fastening When, it is easy to make the tube wall at the fabrication hole 32 of metal side tube to form bulging deformation, had not only influenced the quality of subsequent workpiece installation, but also make Metal side tube is impaired.

Utility model content

The purpose of this utility model is to provide a kind of furniture metallic square tube frame stull for overcoming prior art defect with Overlapped at stull right angle connector.

The technical side of overlapped a kind of furniture metallic square tube frame stull described in the utility model and stull right angle connector Case is as follows: overlapped the furniture metallic square tube frame stull and stull right angle, and connector includes: attachment base and tensioner component；Institute Attachment base is stated equipped with connector, the connector is equipped with one for accommodating the empty slot of tensioner component；The tensioner component includes tensioner Jacking block, tensioner screw；There is tensioner screw hole on the tensioner jacking block；After the tensioner component is packed into the empty slot of the connector, The section of formation is identical as the section internal via shape of metal side tube connected, and the section inner hole of contact cross-section and metal side tube is cut The corresponding nominal dimension in face is equal, and contact cross-section actual size presses basic hole system clearance fit value.

Further, after the tensioner component is packed into the empty slot of the connector, there is chamfering in the end of the connector.

Further, after the tensioner component is packed into the empty slot of the connector, the chamfer dimesion of the end of the connector For (0.5~2) × 45 °, or (0.5~2) × 30 °.

Further, the screw thread of tensioner screw used in the tensioner component is regular screw threads, or is left hand thread.

Further, tensioner screw used in the tensioner component is the common tensioner screw of interior hexagonal, or is commonly risen for a word Tight screw, or be the common tensioner screw of cross, or be the common tensioner screw of outer-hexagonal.

Further, there are two tensioner screw hole and two tensioner screws on the tensioner jacking block of the tensioner component.

The user of overlapped a kind of furniture metallic square tube frame stull described in the utility model and stull right angle connector Method is: the tensioner screw being screwed into the tensioner screw hole of the tensioner jacking block, forms the tensioner component；By the tensioner Component is put into the empty slot of the connector；The connector is packed into the port of metal side tube, the port of square tube is made to be close to the company Then the end face of joint chair rotates tensioner screw by the fabrication hole on metal side tube with spanner, makes tensioner screw to empty slot bottom It stretches out, under the action of screw thread, the tensioner jacking block will be to the reverse movement of tensioner screw moving direction, the tensioner jacking block Upper surface will hold out against the inner wall in metal side tube；Then, the attachment base is mounted on separately by bolt by design requirement The side of one metal side tube；Two metal side tubes just form reliable right angle connection.

The beneficial effect of overlapped a kind of furniture metallic square tube frame stull described in the utility model and stull right angle connector Fruit is: after being packed into the empty slot of the connector due to the tensioner component, the section that the connector is formed and the metal being connect Tube section internal via shape is identical, and the corresponding size of the contact cross-section takes the lower deviation of nominal dimension, in the inner hole of metal tube It is negligible with the gap of the contact cross-section gabarit, when the tensioner jacking block holds out against metal tube under the action of tensioner screw While upper inside wall, the bottom of the connector also synchronizes the inner wall held out against in metal tube lower part, and such structure not will cause Metal tube deformation, and since contact area is big, connection it is more reliable.
