Description

Technical Field

[0001] The utility model relates to the field of hardware, and particularly to a connecting rod, a connection structure and a door and window system. Background Art

[0002] In the existing door and window systems, some fittings (such as corner connectors, hinges or drivers, etc.) need to be fixed to a connecting rod through a connection block. For this purpose, the patent No. 202320851125.X discloses a connecting rod structure with high fault tolerance, which includes a connecting rod and a fault tolerance adjustment assembly. The fault tolerance adjustment assembly includes an adjustment member and a locking member. The adjustment member can slide along the length direction of the connecting rod in an unlocked state, and the connecting rod is provided with a closed surface; in the locked state, the locking member passes through the adjustment member and pierces the closed surface to press the adjustment member against the connecting rod, thereby completing the assembly of the adjustment member and the connecting rod. Finally, the fitting is connected to the adjustment member and fixed to the connecting rod.

[0003] Among them, to avoid interference between the locking member and the connecting rod after piercing the closed surface, a locking groove is further provided on the connecting rod, and the locking groove can be penetrated by the locking member after piercing the closed surface. With such a setting, since a locking groove also needs to be machined on the connecting rod, the processing technology difficulty is increased, and thus the cost is increased.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0037] Embodiment 1

[0038] Refer to Figure 1-2 , the present utility model discloses a connecting rod 1, which includes a base and a clamping plate 13 provided on the base and used for sliding and clamping cooperation with a connecting block 2. The base includes a bottom wall 11 and a connecting wall 12 vertically connected to the top of the bottom wall 11; the clamping plate 13 is arranged parallel to the bottom wall 11, and the connecting wall 12 is connected to the bottom of the clamping plate 13. Thus, the bottom wall 11, the connecting wall 12, and the clamping plate 13 form an approximate "I" - shaped structure.

[0039] Specifically, the connecting wall 12 is connected to the bottom of the clamping plate 13 and is arranged close to the left side of the clamping plate 13, so that the left and right sides of the clamping plate 13 respectively protrude to form a second convex strip 132 and a first convex strip 131, and the width of the first convex strip 131 is much larger than the width of the second convex strip 132 (the width here is the width in the left - right direction). Specifically, the first convex strip 131 sequentially includes a first body part 1311 through which a locking member 3 can pass and a second body part 1312 connecting the first body part 1311 along the width direction, and the thickness of the first body part 1311 is less than the thickness of the second body part 1312. At the same time, the thickness of the first body part 1311 is also less than the thickness of the connecting wall 12 and the second convex strip 132, that is, the thicknesses on both the left and right sides of the first body part 1311 are greater than the thickness of the first body part 1311. In addition, the first convex strip 131, the connecting wall 12, and the bottom wall 11 enclose a first groove 14 into which the locking member 3 can extend, and the second convex strip 132, the connecting wall 12, and the bottom wall 11 enclose a second groove 15.

[0040] Therefore, when the connecting rod 1 of the present utility model is adopted, since the first groove 14 into which the locking member 3 can extend is formed on the connecting rod 1, there is no need to separately provide a groove on the connecting rod 1 for the locking member 3 to extend into, thereby reducing the processing difficulty of the process and thus reducing the cost. In addition, since the thicknesses on both sides of the first body portion 1311 are greater than the thickness of the first body portion 1311, when the locking member 3 passes through the first body portion 1311 and extends into the first groove 14, it will not cause deformation of other parts, thereby ensuring the reliability of the connection. In addition, the smaller thickness of the first body portion 1311 is also more convenient for the locking member 3 to pierce through.

[0041] Preferably, the thickness of the second body portion 1312 is the same as the thickness of the second rib 132, so that the overall structure is more balanced, and when the locking member 3 passes through the first body portion 1311, the clamping plate 13 is also more balanced in force.

[0042] In addition, on the left and right sides of the bottom wall 11, there are also provided upwardly extending limiting convex portions 111. Preferably, the limiting convex portions 111 are bumps integrally formed on the bottom wall 11. Thus, by providing the limiting convex portions 111, the two sides of the connecting block 2 can be limited, thereby preventing the connecting block 2 from shifting, and further ensuring the reliable stability of the connecting rod 1.

[0043] In this embodiment, the bottom wall 11, the connecting wall 12 and the clamping plate 13 are integrally formed.

[0044] Embodiment 2

[0045] Refer to Figure 3-5 The present utility model also provides a connection structure, including the connecting rod 1, the connecting block 2 and the locking member 3 of the above Embodiment 1, wherein the connecting block 2 is slidably clamped on the clamping plate 13; the locking member 3 sequentially passes through the connecting block 2 and the connecting rod 1 and extends into the first groove 14, and the locking member 3 is used to fix the connecting block 2 on the connecting rod 1.

[0046] Specifically, the connecting block 2 includes a top wall 21 and two side walls 22 respectively provided at the lower parts on both sides of the top wall 21. The top wall 21 and the two side walls 22 enclose a clamping groove 25, and the connecting block 2 is slidably clamped on the clamping plate 13 through the clamping groove 25. Thus, in the unlocked state, the connecting block 2 can slide along the length direction of the clamping plate 13 through the cooperation of the clamping groove 25 and the clamping plate 13.

[0047] Specifically, in order to improve the smoothness of sliding, a clamping portion 23 extending in the horizontal direction is further provided on the side wall 22. Preferably, the clamping portion 23 is a convex block integrally formed on the side wall 22, and the convex blocks on the two side walls 22 are arranged oppositely; wherein, the convex block on the right side wall 22 is inserted into the first groove 14, and the convex block on the left side wall 22 extends into the second groove 15, so as to clamp the clamping plate 13 in a surrounding manner.

[0048] Furthermore, the connecting block 2 further includes a convex platform 24 provided on the top of the top wall 21. An installation hole 241 that penetrates through and allows the locking member 3 to extend into is provided on the convex platform 24; preferably, the locking member 3 is a screw, and the installation hole 241 is a threaded hole that is threadedly engaged with the screw.

[0049] In addition, a punch 31 is further provided at the bottom of the locking member 3; thus, when it is necessary to lock the connecting block 2 on the connecting rod 1, the locking member 3 can be rotated to drive the locking member 3 to gradually move in a direction closer to the connecting rod 1. When the punch 31 of the locking member 3 abuts against the top of the clamping plate 13, the preliminary locking of the connecting block 2 can be achieved at this time; subsequently, continue to rotate the locking member 3 to make the locking member 3 continue to approach the connecting rod 1. At this time, the punch 31 on the locking member 3 can pierce through the clamping plate 13 and finally extend into the first groove 14. At this time, the connecting block 2 is completely locked on the connecting rod 1. Subsequently, door and window accessories such as hinges, corner connectors, and drivers can be connected to the connecting block 2.

[0050] In this embodiment, the top wall 21, the two side walls 22, and the convex platform 24 are integrally formed.

[0051] In this embodiment, the connecting rod 1 can be made of aluminum alloy material, so as to facilitate the punch 31 on the locking member 3 to pierce through.

[0052] Embodiment III

[0053] Refer to Figure 6 , the present invention further provides a door and window system, which includes a profile member 4 and the connection structure of the second embodiment above, and the connecting rod 1 is installed on the profile member 4. Wherein, a sliding groove 41 is provided on the profile member 4, and the connecting rod 1 is slidably arranged on the sliding groove 41.

[0054] To sum up, a connecting rod 1, a connection structure and a door and window system provided by the present invention have the following beneficial effects:

[0055] (1) For the connecting rod 1 of the present invention, the first rib 131, the connecting wall 12, and the bottom wall 11 enclose to form a first groove 14 for the locking member 3 to extend into. With such a setting, there is no need to separately provide a groove on the connecting rod 1 for the locking member 3 to extend into, thereby reducing the processing technology difficulty and thus reducing the cost.

[0056] (2) The connecting rod 1 of the present utility model has the thickness on both sides of the first body portion 1311 greater than that of the first body portion 1311. With such a setting, when the locking member 3 passes through the first body portion 1311 and extends into the first groove 14, it will not cause deformation of other parts, thus ensuring the reliability of the connection. In addition, the smaller thickness of the first body portion 1311 is also more convenient for the locking member 3 to pierce through.
