Description

Technical Field

[0001] The present application relates to the technical field of bolts, and in particular to a hand-tightened bolt. Background Art

[0002] In some special working environments, it is not easy to quickly load and unload bolts. The loading and unloading of bolts requires corresponding tools. For example, in high-altitude operations, underwater operations, and operations in narrow spaces, the use of specific tools may become an obstacle to the working process. In order to load and unload bolts more conveniently, people have added a structure to the end of the bolt to facilitate the hand to exert force.

[0003] The existing Chinese patent with the announcement number CN205260541U discloses a multifunctional butterfly bolt, including a bolt body and a hand-tightening piece, wherein the bolt body includes a screw head and a screw rod, wherein the screw rod is concentrically arranged on the bottom surface of the screw head, and the hand-tightening piece is detachably mounted on the top surface of the screw head, wherein the top surface of the screw head is provided with a recess, and the hand-tightening piece includes a protrusion and a butterfly-shaped protruding wing.

[0004] Although the above device is provided with a butterfly-shaped convex wing for easy hand application, the screw will lose the abutment force on one side after being loosened. If the bolt cannot be grasped in time at this time, the bolt will fall off, causing adverse consequences. In response to the above-mentioned related technologies, the applicant has proposed a method that is easy to tighten by hand, and the fingers can still hold the bolt while the bolt is loosened. Utility Model Content

[0005] In order to allow fingers to still hold the bolt when the bolt is loosened, the present application provides a hand-tightened bolt.

[0006] The present application provides a hand-tightened bolt adopting the following technical solution:

[0007] A hand-tightening bolt comprises a bolt body, characterized in that: a hand-tightening seat is sleeved on the threaded end of the bolt body, the top of the hand-tightening seat is sleeved on and abuts against the head and side wall of the bolt body, and "C"-shaped holding rings are symmetrically fixed on both sides of the hand-tightening seat, and the opening side of the holding ring extends outward; a positioning clamping structure is provided on the hand-tightening seat, and when the hand-tightening seat is sleeved on the head of the bolt body, the side wall of the hand-tightening seat is elastically clamped and positioned on the side wall of the bolt body along the extension direction of the bolt body.

[0008] By adopting the above technical solution, the "C"-shaped pinching ring in the design enables the user to easily pinch and rotate the bolt. The open side of the pinching ring extends outward, providing the user with a larger pinching area and a more comfortable grip, which helps to apply a more stable and uniform force when rotating the bolt. The design of the positioning clamping structure ensures the firm installation of the hand-tightening seat on the bolt body, preventing possible slippage or loosening during rotation.

[0009] Preferably, the positioning clamping structure includes a clamping spring and a clamping groove, the clamping springs are fixed at intervals on the side of the hand-tightening seat close to the bolt body, the clamping springs are respectively abutted against the side wall of the bolt body and bent; the clamping groove is opened on the side wall of the bolt body corresponding to the clamping spring, and the clamping spring is accommodated in the clamping groove.

[0010] By adopting the above technical solution, the snap-fit ​​spring sheets are fixed at intervals on one side of the hand-tightening seat close to the bolt body. These spring sheets will bend when abutted by the side wall of the bolt body. The elastic deformation of the bending increases the tightness and stability of the snap-fit ​​structure. When the snap-fit ​​spring sheets are accommodated in the snap-fit ​​grooves, they will be further firmly fixed on the bolt body, preventing the hand-tightening seat from slipping or loosening during rotation, thereby ensuring the stability and reliability of the bolt connection.

[0011] Preferably, the outer edge of the pinching ring is provided with rounded corners.

[0012] By adopting the above technical solution, the rounded corner design makes the edge of the grip ring smoother, reducing the friction and pressure on the user's fingers or palms during use. This helps to improve the user's comfort when operating for a long time or frequently using hand-tightening bolts, and reduces hand fatigue and discomfort.

[0013] Preferably, a gap is left between the clamping spring piece and the head of the bolt body.

[0014] Preferably, the distance between the two opposite clamping springs is set to correspond to the thread minor diameter distance of the bolt body.

[0015] Preferably, the head of the bolt body is arranged at a height higher than the top surface of the hand-tightening seat.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] The "C"-shaped pinch ring in the design allows users to easily pinch and rotate the bolt. The open side of the pinch ring extends outward, providing users with a larger pinching area and a more comfortable grip, which helps to apply a more stable and uniform force when rotating the bolt. The positioning clamping structure design ensures that the hand-tightening seat is firmly installed on the bolt body, preventing possible slippage or loosening during rotation.

[0018] The clamping springs are fixed at intervals on one side of the hand-tightening seat close to the bolt body. These springs will bend when they are abutted by the side wall of the bolt body. The elastic deformation of this bending increases the tightness and stability of the clamping structure. When the clamping springs are accommodated in the clamping grooves, they will be further firmly fixed on the bolt body, preventing the hand-tightening seat from slipping or loosening during the rotation process, thereby ensuring the stability and reliability of the bolt connection.

[0019] The rounded design makes the edge of the grip ring smoother, reducing the friction and pressure on the user's fingers or palms during use. This helps improve the user's comfort when operating for a long time or frequently using hand-tightening bolts, reducing hand fatigue and discomfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] The present application embodiment discloses a hand-tightened bolt, referring to Figure 1 , 2 , including a bolt body 1, which is provided with a hand-tightening seat 2 from the threaded end sleeve toward the other end. The top of the hand-tightening seat 2 is sleeved and abuts against the head and side wall of the bolt body 1, so that the hand-tightening seat 2 is stably connected to the bolt body 1 to prevent falling off.

[0026] Reference Figure 2 , 3 The head of the bolt body 1 is set higher than the top surface height of the hand-tightening seat 2. When tools are needed to be used for disassembly, the shape of the bolt head is still retained, which is convenient for docking with the tool. At the same time, the bolt head protrudes from the hand-tightening seat 2 and makes it more convenient for construction workers to observe the shape of the bolt head.

[0027] Reference Figure 2 , 3 When the hand-tightening seat 2 is sleeved on the head of the bolt body 1, the hand-tightening seat 2 is kept in position along the extension direction of the bolt body 1 through the positioning clamping structure 4. The positioning clamping structure 4 includes a clamping spring 41 and a clamping groove 42. The clamping springs 41 are respectively fixed at intervals on the side of the hand-tightening seat 2 close to the bolt body 1. The clamping springs 41 are respectively abutted against the side wall of the bolt body 1 and bent; the clamping groove 42 is opened on the side wall of the bolt body 1 corresponding to the clamping spring 41, and the clamping spring 41 is accommodated in the clamping groove 42.

[0028] Reference Figure 2 , 3A gap is left between the snap-fit ​​spring piece 41 and the head of the bolt body 1 , thereby preventing the snap-fit ​​groove 42 corresponding to the snap-fit ​​spring piece 41 from being opened at a narrow connection between the bolt body 1 and the head of the bolt body 1 , which affects the strength.

[0029] Reference Figure 2 , 3 The distance between the two opposite snap-fit ​​spring pieces 41 corresponds to the thread minor diameter distance of the bolt body 1, so that the snap-fit ​​spring pieces 41 can pass through the threaded end of the bolt body 1 by screwing, thereby avoiding scratches on the thread. At the same time, this arrangement facilitates the disassembly of the hand-tightening seat 2, and is easy to replace and maintain.

[0030] Reference Figure 2 , 3 , "C"-shaped holding rings 3 are symmetrically fixed on both sides of the hand-tightening seat 2, and the opening side of the holding ring 3 extends outward; the setting of the holding ring 3 prolongs the distance from the force application point to the bolt, and the twisting is more labor-saving; and the "C"-shaped setting enables the fingers to have abutment surfaces on both sides after inserting the holding ring 3, so that no matter whether it is positive or negative thread or installation or disassembly, it can better exert force from two directions without slipping out of the hand; and the "C"-shaped setting enables the holding groove to keep a good holding posture at any time, even if the bolt is out of the screw hole, the fingers will not lose force and cause the bolt to fall off.

[0031] Reference Figure 2 , 3 The outer edge of the pinch ring 3 is provided with a rounded corner, so that the construction workers will not feel pain due to the strong edge pressure or be scratched due to the sharp edge when twisting vigorously.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
