[0025] It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined or described in one drawing, it will not need to be further specifically discussed and described in the description of subsequent drawings.

[0026] To solve the technical problems in the background art, as shown in Figs. 1-2 The present application provides a technical solution: a stainless steel pipe cutting angle gauge, characterized by:

[0027] The fixed seat 1 is the base of the gauge, designed to stably support the entire structure, usually made of solid materials such as steel structure or heavy plastic, to ensure stability and durability during use. The fixed ring 2 is fixed on the fixed seat 1, forming a ring structure, and the vertical plane 3 on the outer side wall is used to install the slide rail 4. The slide rail 4 is vertically installed on the vertical plane 3 of the side wall of the fixed ring 2, used to guide the vertical movement of the sliding block 5. The slide rail 4 can be a circular or square track to ensure smooth sliding of the sliding block 5. The sliding block 5 contains a groove 6 that fits the slide rail 4, allowing the sliding block 5 to slide vertically along the slide rail 4. The sliding block 5 is usually made of wear-resistant materials to reduce friction during sliding. The guide rail 7 passes horizontally through the top end of the side wall of the sliding block 5, allowing the guide rail 7 to slide horizontally within the sliding block 5. The two ends of the guide rail 7 are connected to the limiting block 8 and the fixed block 9 respectively to ensure the stability and correct position of the guide rail 7. The fixed block 9 is installed with the positioning block 10, which is used to fit with the pipe cut. The bearing seat 11 is installed in the fixed ring 2, the outer ring is fixed with the fixed ring 2, and the inner ring top is provided with the sleeve 12. The sleeve 12 rotates with the inner ring of the bearing seat 11. The inner side wall of the sleeve 12 is a stepped structure composed of two sections of different inner diameters, the upper end inner diameter is larger than the lower end to adapt to different sizes of pipes. The smaller inner diameter of the lower end forms an abutting surface for lifting the bottom of the pipe. The arc block 13 and the limiting block 14 form the structure of the upper end of the sleeve 12, the two limiting blocks 14 are oppositely arranged, and the opposite surfaces are provided with protrusions 15 for fitting with the pipe cut. The pointer 16 is installed on the top wall of the fixed ring 2 coaxially with the positioning block 10, used to indicate the position of the positioning block 10. The dial 17 is installed beside the fixed ring 2, and the scale 18 is marked on it to indicate the deflection angle of the cutout aligned with the positioning block 10.

[0028] It should be noted that the dial 17 is an important part of the gauge, used to read the deflection angle of the pipe cut. The edge of the dial 17 is designed to be tangent to the outer side wall of the fixed ring 2, which makes the dial 17 closely fit the fixed ring 2, ensuring the stability of the dial 17 and the accuracy of the reading during measurement.

[0029] Further, the limiting stop 14 is a key component for ensuring the correct alignment of the pipe cut. Each limiting stop 14 has a raised surface 15 on its opposite side, which is adapted to the pipe cut to ensure the accuracy of the measurement. The arc block 13 is used in conjunction with the limiting stop 14, and the connection between the limiting stop 14 and the arc block 13 is designed to be detachable, which means they can be connected together through bolts, buckles, threads, or other quick-release mechanisms. This design allows users to easily replace or adjust the limiting stop 14 and the arc block 13 as needed. The advantage of detachable connection is that when the limiting stop 14 needs to be replaced due to wear or damage, users can quickly replace it without replacing the entire sleeve 12, thereby reducing maintenance costs. In addition, this design also allows quick adjustment or replacement of the limiting stop 14 with different shaped raised surfaces 15 to adapt to different measurement scenarios according to different types of pipes or specific measurement requirements.

[0030] It should be noted that the guide surface 19 is designed as an inverted V-shaped structure. This structure helps to guide the pipe cut to align smoothly with the raised surface 15, ensuring accurate positioning of the pipe cut during measurement. The inverted V-shaped guide surface 19 provides an intuitive guide, making it easier for users to align the pipe cut with the raised surface 15. This design reduces errors during alignment and improves measurement accuracy. The guide surface 19 is located at the upper end of the raised surface 15, which means it is on the opposite side of the limiting stop 14, the top of the raised surface 15. This layout allows the guide surface 19 to function when the pipe is inserted or removed from the gauge, ensuring that the pipe cut can be smoothly aligned with the raised surface 15 along the guide surface 19.

[0031] Further, the inner diameter of the lower end of the sleeve 12 is designed to be smaller than the outer diameter of the steel pipe to be detected. This design allows the smaller inner diameter of the sleeve 12 to have a platform to hold and limit the steel pipe that has penetrated into the sleeve 12, preventing the steel pipe from sliding or rotating during the measurement process, thereby ensuring the stability and accuracy of the measurement.

[0032] It should be noted that the handle 20 is an additional component of the gauge, designed to improve the convenience and comfort of operation. The handle 20 is usually ergonomically shaped to ensure a comfortable and stable grip when handling or operating the gauge. The handle 20 is arranged on both sides of the fixed base 1, and this symmetrical layout provides a balanced support point, allowing users to easily lift or move the entire gauge from either side. The handle 20 is fixed to the fixed base 1 by bolts, welding, or strong glue, etc. These connection methods need to ensure that the handle 20 is firmly connected to the fixed base 1 to withstand the forces that may occur during use.

[0033] It should be noted that the cross section of the slide rail 4 is designed as a trapezoid, and this asymmetric design helps to improve the structural stability and load capacity of the slide rail 4. The two parallel sides (the bottom side and the top side) of the trapezoid are of different lengths, and the length of the side connected to the fixed ring 2 is smaller than that of the opposite side. When the slide rail 4 with the trapezoidal cross section is connected to the fixed ring 2, the longer side provides a larger contact area, increasing the connection stability between the slide rail 4 and the fixed ring 2, and reducing the swing or vibration of the slide rail 4 during use. At the same time, because of the structural feature of one end being larger and the other end being smaller, the slide rail 4 also has a self-locking feature, that is, the slide block 5 is locked to prevent it from slipping off the slide.

[0034] While the embodiments of the present application have been shown and described, it is to be understood that the embodiments can be varied, modified, replaced and changed in many ways without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
