According to the connection structure provided by the embodiment of the disclosure, the truss 500 is connected with the end cup 30, and the truss 500 is indirectly connected with the bolt 10 through the matching of the internal thread 301 of the end cup 30 and the external thread 102 at one end of the bolt 10; since the bolt 10 penetrates through the first through hole 401 of the bolt sleeve 40 from the inner side of the bolt sleeve, and the size of the bolt head 103 at the other end of the bolt 10 is larger than the aperture of the first through hole 401, that is, one end of the bolt 10 can penetrate through the inner side of the bolt sleeve 40, and the bolt head 103 can be sleeved on the inner side of the bolt sleeve 40, it can be understood that the bolt 10 is connected with the bolt sleeve 40, further, the truss 500 is indirectly connected with the bolt sleeve 40, the bolt 10 can move at the first through hole 401 of the bolt sleeve 40, and only the bolt head 103 can be sleeved by the bolt sleeve 40; in addition, the bolt 10 is further provided with a polygonal column 101 matched with the polygonal sleeve 20, and it can be understood that the bolt 10 can be easily rotated by screwing the polygonal sleeve 20, and the connection between the truss 500 and the bolt sleeve 40 can be realized by screwing the bolt 10 and the end cup 30 more tightly through the matching of the external thread 102 of the bolt 10 and the internal thread 301 of the end cup 30.
The connection structure provided by the embodiment of the disclosure is applied to realize the connection between the truss and the truss, and for some situations requiring flexible installation or disassembly of the truss, for example, when a target truss in the truss needs to be replaced, the polygonal sleeve can be screwed to move the bolt towards the inner side direction of the bolt sleeve, so that the target truss can be easily disassembled; furthermore, after the new truss is connected with the end cup, one end of the end cup with the internal thread is aligned to one end of the bolt with the external thread, and the polygonal sleeve is screwed to enable the bolt to move towards the outer side direction of the bolt sleeve, so that the new truss is installed. Therefore, the connection structure provided by the embodiment of the disclosure can improve the flexibility of the connection mode between the trusses.
In some embodiments of the present disclosure, referring to fig. 1, the truss 500 may be a metal pipe, a fiber pipe, a plastic pipe, or the like, and the end cup 30 and the truss 500 may be connected by a screw or a rivet, or may be connected by welding.
In some embodiments of the present disclosure, referring to fig. 2, the truss 500 may also be a solid truss, the material of the truss 500 may be wood, rattan, bamboo, etc., the end cup 30 is concealed in the truss 500, and the connection of the truss is realized by the matching of the internal thread 301 of the end cup 30 and the external thread 102 of the bolt 10. That is, the connection of the truss is realized under the condition that the end cup 30 is not exposed, so that the integral aesthetic property of the truss after the connection is finished is improved.
In some embodiments of the present disclosure, the bolt sleeve 40 may be a circular ring structure. By arranging the bolt sleeves 40 in a circular ring structure, the truss can be connected on a plane to form a rectangular or arc-shaped equal-plane framework.
In some embodiments of the present disclosure, the bolt sleeve 40 may include two detachably connected hollow hemispheres. For example, referring to fig. 1, each of the hollow hemispheres includes a cut edge 41 and a first through hole 401, and a pin hole 411 is provided on the cut edge 41. During installation, the bolt 10 penetrates out of the inner side of each hollow hemisphere, one end of the bolt 10 extends out of the hollow hemispheroids, the bolt head 103 at the other end of the bolt is sleeved on the inner sides of the hollow hemispheroids, the two hollow hemispheroids are folded after the bolt 10 penetrates through the bolt holes 411 according to design requirements, and the two hollow hemispheroids are stably connected. In one case, a symmetrical center hole (not shown) may be formed on the axis of the two hollow hemispheres passing through the center of the circle, and after the two hollow hemispheres are closed, the two hollow hemispheres may be tightened by a center bolt (not shown) inserted through the center hole. The connection of the truss in three dimensions can be realized by two detachably connected hollow hemispheres included in the bolt sleeve 40 to form a three-dimensional framework.
In some embodiments of the present disclosure, a smooth column 104 is between the polygonal column 101 and the bolt head 103, and the diameter of the first through hole 401 is larger than the diameter of the smooth column 104. In some related technologies in the prior art, a hole needs to be precisely drilled and a thread adapted to a bolt needs to be machined, so that the connection between the truss and the bolt sleeve can be realized, and the installation position of the truss after the connection is completed is fixed and cannot be adjusted.
In some embodiments of the present disclosure, referring to fig. 5, the maximum diameter of the polygonal column 101 may be larger than the diameter of the smooth cylinder 104, and the aperture diameter of the first through-hole 401 may be larger than the maximum diameter of the polygonal column 101. Therefore, the position of the bolt 10 after the connection is completed can be adjusted to a greater extent, so that the flexibility of truss installation is further improved. In a case where the bolt 10 and the polygonal column 101 are of an integral structure, setting the aperture of the first through hole 401 to be larger than the maximum diameter of the polygonal column 101 can facilitate the threading of the bolt 10 from the inside of the bolt housing 40.
In some embodiments of the present disclosure, referring to fig. 1, one surface of the bolt head 103 near the polygonal column 101 may be configured as a cambered surface that fits the inner wall of the bolt sleeve 40; one face of the polygonal sleeve 20 may be provided as a curved face which is fitted to the outer wall of the bolt housing 40. In some existing related technologies, an arc surface where a bolt sleeve contacts a bolt is generally processed into a plane, such a design makes a connection angle between the bolt and the bolt sleeve fixed, and a function of fine adjustment of the angle cannot be achieved, and for a bolt sleeve without an angle adjustment function, a position or an angle of each contact connected with the bolt needs to be determined more accurately, especially for three-dimensional connection of a three-dimensional framework, the position or the angle of each contact is slightly deviated, so that a situation of poor connection and matching between trusses is likely to occur, which leads to a mismatch with an expected framework structure, and this undoubtedly increases a processing difficulty of the bolt sleeve. In the embodiment of the present disclosure, the bolt sleeve 40 retains its own radian, so that the bolt 10 connected to the bolt sleeve 40 can be slightly adjusted in angle, and the bolt 10 and the polygonal sleeve 20 are both provided with arc surfaces to be matched with the arc contact surface of the bolt sleeve 40, so that the bolt 10 and the polygonal sleeve 20 can be tightly attached to the bolt sleeve 40, a better contact effect is formed, and meanwhile, the processing requirement on the bolt sleeve 40 is reduced.
In some embodiments of the present disclosure, as shown with reference to fig. 5, the interior of the bolt sleeve 40 may be provided with a resilient stop 600. For example, a metal spring ball may be hidden inside the bolt sleeve 40 as the elastic stop 600, on one hand, the bolt 10 inserted into the bolt sleeve 40 may be kept to extend out of the bolt sleeve 40, so as to prevent the bolt 10 from being completely retracted into the bolt sleeve 40; on the other hand, the operator can easily retract the bolt 10 toward the inside of the bolt sleeve 40 by pressing the metal spring ball to contract the metal spring ball, which is convenient for installation.
In some embodiments of the present disclosure, referring to fig. 1, the central axis of the bolt 10 may be provided with a second through hole (not shown) that may be used to pass a wire rope 700 and/or a cable (not shown). By inserting the steel cable 700 into the bolt 10, on one hand, the steel cable 700 can be used to increase the load-bearing strength of the overall frame as a pre-stress; on the other hand, since the position and angle of the connection between the bolt 10 and the bolt sleeve 40 can be finely adjusted, in practical application, the steel cable 700 can be used to string the truss, the bolt, the polygonal sleeve, the end cup, the bolt sleeve and other components together in advance to form a structure similar to a chain, so as to facilitate quick assembly, and the steel cable is more suitable for a framework which needs to be assembled in a short time during disaster relief. Through setting up the second through-hole, also for walking the line and provide convenience, wear to locate the second through-hole that bolt 10 set up with cables such as electric wire, signal line, can reduce exposing of cable, when protecting the cable, strengthened overall structure's aesthetic property.
In some embodiments of the present disclosure, one end of the end cup 30 may be provided with a bushing nut (not shown) provided with an internal thread 301 that mates with the external thread 102. The internal thread 301 of end cup 30 one end can be the inside of direct processing in end cup 30, but because end cup 30 still need configure into the structure of joinable truss, the course of working is more complicated, if direct processing internal thread 301 on end cup 30, influence this internal thread 301's quality because of other processing and treatment processes easily, compare in setting up the bushing nut through the one end at end cup 30, the mode of processing internal thread 301 on this bushing nut, the latter changes and realizes standardized production, moreover, bushing nut is more convenient for change, if internal thread 301 decreases, it can to update bushing nut, need not to abandon whole end cup, flexibility and practicality are stronger.
In some embodiments of the present disclosure, as shown with reference to fig. 1 and 4, the end cup 30 may be provided with a protective collar 302, with a truss 500 mounted inside the protective collar 302. For example, the protective ring 302 may be made of plastic, silicone, fiber, or metal, etc. to protect and identify the truss, and enhance the overall aesthetic appearance.
A second aspect of an embodiment of the present disclosure provides a framework comprising: a connection structure provided according to a first aspect of an embodiment of the present disclosure; and the trusses are connected through the connecting structure.
According to the framework provided by the embodiment of the disclosure, a plurality of trusses are connected through the connecting structure provided by the first aspect of the embodiment of the disclosure, in the connecting structure, the trusses are connected with the end cups, and the trusses are indirectly connected with the bolts through the matching of the internal threads of the end cups and the external threads of one ends of the bolts; the bolt is arranged in the first through hole of the bolt sleeve in a penetrating mode from the inner side of the bolt sleeve, and the size of the bolt head at the other end of the bolt is larger than the aperture of the first through hole, namely one end of the bolt can penetrate out of the inner side of the bolt sleeve and the bolt head can be sleeved on the inner side of the bolt sleeve; in addition, the bolt is also provided with a polygonal column matched with the polygonal sleeve, and the bolt can be easily rotated by screwing the polygonal sleeve. Therefore, the external threads of the bolt are matched with the internal threads of the end cup, so that the bolt and the end cup are screwed more and more tightly, and the connection between the truss and the bolt sleeve can be realized.
