Description

Technical Field

[0001] The utility model belongs to the technical field of fasteners, and particularly relates to a fastener with a buckling structure. Background Technique

[0002] Fasteners are a type of mechanical parts used to connect and fix two or more parts or components. They tightly connect various parts together through threads or other means to form a complete structure.

[0003] For example, the Chinese patent with the publication number CN216111665U discloses a fastener with a buckling structure. Aiming at the problem that the existing one cannot be applied to fasten objects with different thicknesses, the following solution is proposed. It includes a bolt and a female sleeve. A sleeve is threadedly connected to the bolt. A buckling mechanism is arranged on the sleeve. The buckling mechanism includes a top plate. The top plate is fixedly connected to the sleeve. A sliding cavity is opened on the top plate. Two trapezoidal plates are slidably installed in the sliding cavity. The same first spring is fixedly installed on the two trapezoidal plates. The middle of the first spring is fixedly connected to the inner wall of the sliding cavity. Both trapezoidal plates cooperate with the female sleeve. Two vertical cavities are opened on the female sleeve. An auxiliary mechanism is arranged on the female sleeve. The auxiliary mechanism includes two second springs. The utility model can quickly fasten objects with different thicknesses, has a good fastening effect, a wide application range, is simple to use and convenient to operate.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use. For example, when the device is fixing, only movable plates can be used to rotate the bolt. The volume of the adjustable wrench is large and the weight is heavy, which is not convenient for the staff to carry around. At the same time, when the device rotates the bolt, the female sleeve and the sleeve are limited in position, which causes the sleeve to rotate easily when the bolt rotates. If the female sleeve is held by hand, the sleeve will still rotate, which will affect the fixation. In view of this, we propose a fastener with a buckling structure. Content of the Utility Model

[0006] The purpose of the utility model is to provide a fastener with a buckling structure to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a fastener with a buckling structure, including:

[0008] A threaded rod, a hexagonal block is fixedly installed at the bottom end of the threaded rod. A hexagonal groove is opened at the bottom of the hexagonal block. A cross groove is opened in the hexagonal block and at the top of the hexagonal groove. A fixed block is arranged above the threaded rod. A circular groove is opened at the bottom of the fixed block. A sleeve threadedly connected to the threaded rod is arranged in the circular groove.

[0009] A circular groove is provided on the upper part of the sleeve and is located within the circular groove. Two through grooves communicating with the circular groove are provided at the top of the sleeve. Two connecting plates fixed to the fixed block are provided within the circular groove. Two sliding grooves are provided within the fixed block and at the top of the circular groove. A limiting block is slidably installed within each of the two sliding grooves. The lower end of the limiting block passes through the through groove and extends into the circular groove. A U-shaped pull rod is provided at the top of the fixed block. Both ends of the U-shaped pull rod penetrate through the top of the fixed block and extend into the two sliding grooves respectively. The two ends of the U-shaped pull rod are tightly welded to the tops of the two limiting blocks respectively. Springs are sleeved on both ends of the U-shaped pull rod and are respectively located within the two sliding grooves.

[0010] In this technical solution, during use, the annular gasket can be first sleeved on the threaded rod, and then the threaded rod is threadedly installed into the sleeve. Subsequently, the threaded rod and the sleeve are passed through the fastening object. Then, the two connecting plates within the fixed block are aligned with the two through grooves respectively. Subsequently, the fixed block is displaced downward so that the two connecting plates respectively pass through the two through grooves and enter the circular groove. At this time, the two limiting blocks will be squeezed by the top of the sleeve and displaced upward. The springs at the tops of the limiting blocks will be compressed and contract. At this time, the U-shaped pull rod will also be driven upward by the two limiting blocks. The two limiting blocks will completely enter the corresponding sliding grooves. Subsequently, the fixed block can be rotated. The fixed block will drive the two connecting plates and the two limiting blocks to rotate. The two connecting plates will rotate within the circular groove, causing the fixed block to rotate 90°. At this time, the two limiting blocks will be respectively located directly above the two through grooves. Under the action of the elastic force of the spring, the spring will push the limiting block downward, causing the bottom of the limiting block to pass through the corresponding through groove and contact the bottom of the circular groove. At this time, the two limiting blocks will be limited and unable to continue rotating, and under the action of the two connecting plates, the fixed block will no longer be displaced upward;

[0011] Subsequently, the staff can hold the fixed block by hand, and then, under the action of the hexagonal block, hexagonal groove and cross groove provided, the staff can use a socket wrench, hex key or screwdriver to rotate the hexagonal block. Subsequently, the hexagonal block will drive the threaded rod to rotate. When the threaded rod rotates, the sleeve will not rotate together. Under the action of the thread, the threaded rod can be displaced upward, thereby being able to fix the fastening object.

[0012] In the above technical solution, further, an annular gasket is sleeved on the threaded rod.

[0013] In this technical solution, under the action of the annular gasket, it is ensured that the overall device can fix the fastening object more stably.

[0014] In the above technical solution, further, the limiting block is slidably connected to the through groove and the circular groove.

[0015] In this technical solution, it is ensured that the limiting block can slide within the through groove and the annular groove.

[0016] In the above technical solution, further, a rubber pad is fixedly installed on the fixed block, and the hexagonal block and the threaded rod are of an integrally formed structure.

[0017] In this technical solution, under the action of the rubber pad, when the staff holds the fixed block by hand, it is more comfortable, and it can increase the friction between the fixed block and the hand, making the grip more firm; ensuring the structural stability between the hexagonal block and the threaded rod.

[0018] In the above technical solution, further, the U-shaped pull rod is slidably connected to the fixed block and the chute.

[0019] In this technical solution, it is ensured that the U-shaped pull rod can slide with the fixed block and the chute.

[0020] In the above technical solution, further, both ends of the spring are tightly welded to the top of the limiting block and the inner wall of the chute respectively.

[0021] In this technical solution, the structural stability of the spring is ensured.

[0022] In the above technical solution, further, the connecting plate is slidably connected to the annular groove.

[0023] In this technical solution, it is ensured that the connecting plate can slide within the annular groove.

[0024] The beneficial effects of the present utility model are:

[0025] 1. For the fastener of this buckling structure, through the cooperation among the through groove, annular groove, limiting block, chute, spring and U-shaped pull rod set, when the fixed block is installed on the sleeve, there will be no rotation or vertical displacement. When rotating the threaded rod, the staff can hold the fixed block by hand, thereby preventing the sleeve from rotating together with the threaded rod, making the fixing operation more convenient.

[0026] 2. For the fastener of this buckling structure, through the cooperation among the hexagonal block, cross slot and hexagonal groove set, it is ensured that an adjustable wrench, hexagon wrench and screwdriver can be used to drive the hexagonal block to rotate, providing more driving methods. The hexagon wrench is small in volume and light in weight, making it convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS
