The traditional frock handle structure is often single function, cannot satisfy various operation needs, and there are many inconveniences in the operation process.

[0003] On the one hand, the handle of the traditional frock is usually fixed, cannot be rotated according to the actual operation demand. When carrying, storing or carrying out ultrasonic scanning, the operator often needs to adjust his posture or force direction to adapt to the position of the handle, which not only increases the operation difficulty, but also may lead to inaccurate operation or cause frock damage. Especially in the ultrasonic scanning process, the frock needs to be placed in liquid, the traditional handle design often makes the operator's hand directly contact with the liquid, which is neither safe nor sanitary.

[0004] On the other hand, the handle of the traditional frock lacks effective angle positioning mechanism, and the rotation process is prone to transition rotation or cannot be stably stopped. This not only affects the accuracy of operation, but also may cause unnecessary wear and tear or damage to the frock equipment. At the same time, the length design of the traditional handle is often unreasonable, which cannot ensure that the operator maintains enough distance when holding the handle, thereby increasing the risk of direct contact with the frock, which may cause pollution or damage.

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0035] like Figs. 1-3 As shown, this embodiment discloses a rotatable folding handle structure, which is installed on both sides of the fixture 200. The specific structure of the handle assembly 100 includes a handle 1, a rotating handle assembly, and a positioning mechanism. These components work together to enable the handle assembly 100 to rotate at a specific angle on the side wall of the fixture 200.

[0036] In this embodiment, the handle 1 can be manually rotated according to different operating conditions, with three states: 90°, 0°, and -90°. This design allows the handle 1 to adapt to different operational needs, such as when handling, storing, or performing ultrasonic scanning, and can be adjusted to the most suitable position.

[0037] In this embodiment, a notch is provided on the handle 1, and a rotating shaft 6 is connected to the notch. The rotating handle assembly is sleeved on the rotating shaft 6 and placed inside the notch, thereby enabling the handle 1 to rotate relative to the rotating handle assembly. One side of the rotating handle assembly is fixedly connected to the tooling 200, thereby enabling the handle 1 to be connected and installed with the tooling 200.

[0038] In this embodiment, the rotating handle assembly includes a cover plate 2 and a mounting block 3. The cover plates 2 are connected to both sides of the notch, and the two cover plates 2 are connected by the mounting block 3. A ball plug 4 corresponding to the rotating shaft 6 is inserted into the cover plate 2 for positioning the rotating shaft 6 under a certain force.

[0039] In this embodiment, the positioning mechanism includes a slot 5 and a ball plug 4. Through the cooperation of the slot 5 and the ball plug 4, the positioning can be limited under a certain force. When a large force is applied, the slot 5 and the ball plug 4 will disengage on their own.

[0040] Each state is provided with resistance by the ball plunger 4, which corresponds to a pre-machined groove 5 on the rotating shaft 6. The design of the ball plunger 4 not only provides the necessary resistance, allowing the handle 1 to remain stably stationary when rotated to a specific angle, but also achieves precise angular positioning through its unique ball structure and tight fit with the groove 5. The resistance of the ball plunger 4 is adjustable; by adjusting the preload of the internal spring, it can adapt to the needs of different operating forces. This adjustability makes the handle structure more flexible and can meet a wider range of tooling application scenarios.

[0041] In this embodiment, the surface of the rotating shaft 6 is fixedly connected with a positioning pin 7, and a sliding groove corresponding to the positioning pin 7 is arranged in the cover plate 2. The cooperation of the positioning pin 7 and the sliding groove realizes the rotation of the rotating shaft 6 within a certain range, avoiding excessive rotation. This design effectively limits the rotation range of the handle 1, preventing possible structural damage or inconvenience caused by excessive rotation.

[0042] The card slots 5 in this embodiment are arranged at 90°, 0° and -90° of the cross section of the rotating shaft 6. When the ball plug column 4 contacts the card slot 5, a certain jerk feeling is generated, which facilitates the operator to obtain the current angle information. An intuitive feedback mechanism is provided, which enables the operator to immediately know that the handle 1 has been rotated to the predetermined position. The strength of the jerk feeling can also be changed by adjusting the spring pre-tightening force inside the ball plug column 4 to adapt to the preferences of different operators. In addition, the shape and depth of the card slot 5 are also optimized to ensure that the ball plug column 4 can be firmly clamped therein and will not fall off due to slight vibration or external force.

[0043] At the same time, after the ball plug column 4 is clamped to the card slot 5, it is fixed to avoid the handle 1 from naturally swinging and affecting the subsequent ultrasonic scanning process. This fixing mechanism is crucial for maintaining the stability of the tool 200 during the ultrasonic scanning process, which ensures the accuracy and reliability of the scanning results. The fixing mechanism of the ball plug column 4 also has a certain self-locking property, which can maintain the stable position of the handle 1 even under certain external forces. This self-locking property is achieved through the special design of the spring and ball structure inside the ball plug column 4.

[0044] In this embodiment, the ball plug column 4 is provided with a spring inside, which provides a force that makes the ball plug column 4 move towards the rotating shaft 6, thereby better contacting the card slot 5. At the same time, the end of the ball plug column 4 towards the rotating shaft 6 is a ball structure, so that when the ball plug column 4 is clamped with the card slot 5, it can be positioned and clamped without external force, and can be separated under a larger force, which is convenient to use. The design of the ball structure not only increases the contact area between the ball plug column 4 and the card slot 5, but also reduces the friction and wear between them.

[0045] The length of the handle 1 in this embodiment is greater than the height of the tool 200, specifically, the length of the handle 1 in this embodiment is at least 3 times the height of the tool 200, which is convenient for the operator to hold. This length design allows the operator to maintain a sufficient distance when holding the handle 1, avoiding direct contact with the tool 200, thereby reducing the possibility of contamination or damage. The length of the handle 1 can also be customized according to actual needs to meet the needs of different tool sizes and operation habits, but the handle 1 at least extends to the liquid surface and is convenient for the operator to hold.

[0046] AsFig. 3 As shown, the rotating shaft 6 in the embodiment is mounted in the cover plate 2. The positioning pin 7 is mounted on the rotating shaft 6. When the handle is rotated to 90° and -90°, it can play a role in blocking the handle from continuing to rotate. This blocking mechanism is achieved by the design of the positioning pin 7 and the limit position of the sliding groove, which ensures that the handle 1 will not continue to rotate when rotated to the extreme position, thereby protecting the integrity of the overall structure. The mounting method and position of the rotating shaft 6 are also carefully designed to ensure its stability and firmness in the cover plate 2. The accuracy of the cooperation between the positioning pin 7 and the sliding groove is also strictly controlled to ensure the smoothness and accuracy during rotation.

[0047] The tool 200 in the embodiment is an ultrasonic scanning tool. The workpiece is placed in the pre-designed hole slot of the tool 200 and exposes part of the surface. At this time, the ultrasonic wave will sweep the surface of the workpiece along the surface of the tool. At the same time, during the ultrasonic scanning process, the entire tool needs to be placed in a liquid. At this time, the handle 1 is perpendicular to the surface of the tool 200 and extends out of the surface of the liquid, which is convenient for the operator to hold. This design allows the operator to keep the hands dry and clean when holding the handle 1 to perform ultrasonic scanning, avoiding direct contact with the liquid.

[0048] At the same time, the entire tool also needs to be inverted and placed in the liquid for further ultrasonic scanning. The handle 1 of the present application can realize rotation in the opposite direction and keep perpendicular to the surface of the tool 200, which is convenient for the operator to operate. The operator does not need to touch the tool 200 during the entire process, and can also accurately judge the rotation angle. This design greatly improves the convenience and safety of operation, making the ultrasonic scanning process more efficient and reliable.

[0049] In addition, in another embodiment, an angle indicator or scale can also be provided on the handle 1 to more intuitively display the current rotation angle.

[0050] The utility model discloses simple structure, compact, can realize handle rotation and satisfy different equipment use demand. Contain three main orientation, convenient operation. Inside the structure contains the positioning structure, will not cause the rotation excessive phenomenon. This design not only improves the practicability and flexibility of handle structure, also reduces the manufacturing cost and maintenance difficulty, makes it have extensive application prospect in the industry.

[0051] The above description is an explanation of the utility model, not a limitation of the utility model. The scope defined by the utility model is referred to the claims. Within the protection scope of the utility model, any form of modification can be made.
