It is also sometimes used as a safety device to protect the connected parts from excessive loads, providing overload protection. During coupling maintenance, fluid accumulation in the pump chamber or internal leakage from a valve could cause the coupling to actuate, potentially squeezing the operator's hands and injuring them. Therefore, the coupling should be installed with a limit stop.

The inner member is sleeved inside the outer shaft seat, and the inner peripheral surface of the stainless steel outer ring is fixedly connected to the outer peripheral surface of the outer shaft seat. The inner circumference of the inner component is fixedly connected to the outer circumference of the stainless steel inner ring. A rectangular groove 1 is opened at each of the four quadrant points on the outer circumference of the stainless steel outer ring. The outer shaft seat is opened with a rectangular groove 2 that passes through the outer shaft seat at the position corresponding to the rectangular groove 1. The inner end of the anti-rotation pin passes through the rectangular groove 1 and the rectangular groove 2 in sequence outward and inward and is fixedly connected to the outer circumference of the inner component. The slider is mounted on the anti-rotation pin and contacts the outer arc surface of the inner component. An inner stop groove is provided at one end of the stainless steel inner ring, and an outer stop groove is provided at one end of the stainless steel outer ring. It is not convenient to use in conventional couplings, nor is it convenient to adjust according to needs. Its practicality and safety are not high. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] This embodiment, by placing a fastening ring on the coupling, can change the size of the fastening ring and the tightness of the connection with the coupling under the action of the connecting assembly, thereby fine-tuning according to the size of different couplings. At the same time, retractable and adjustable stop rods are provided on both sides of the fastening ring. After the fastening ring fixes the coupling, it can be used in contact with the ground to prevent the coupling from rotating, realizing the anti-rotation stop function. The specific implementation is as follows:

[0028] like Figures 1 to 3 As shown, a coupling anti-rotation stop device includes a fastening ring 1 and a stop rod 2. Side sleeves 8 are provided on both sides of the fastening ring 1. Stop rods 2 are inserted into the two side sleeves 8. The fastening ring 1 includes a first semicircular ring 3 and a second semicircular ring 4 that are symmetrically connected. The first semicircular ring 3 and the second semicircular ring 4 are connected by a connecting component that can adjust the connection range of the first semicircular ring 3 and the second semicircular ring 4. When the fastening ring 1 is mounted on the coupling, the size of the fastening ring 1 and the tightness of the connection with the coupling can be changed under the action of the connecting component, so as to perform fine-tuning according to the size of different couplings. At the same time, telescopically adjustable stop rods 2 are provided on both sides of the fastening ring 1. After the fastening ring 1 fixes the coupling, it can be used in contact with the ground to prevent the coupling from rotating, thereby realizing the anti-rotation stop function.

[0029] Two connecting assemblies are respectively provided at the top and bottom of the connection between the first and second semicircular rings 3 and 4. These connecting assemblies include two connecting blocks 5 symmetrically arranged at the connection between the first and second semicircular rings 3 and 4, and connecting bolts 6 connected to the two connecting blocks 5. The two connecting blocks 5 are respectively provided with threaded holes extending left and right and matching the connecting bolts 6. By rotating the connecting bolts 6, the spacing between the two connecting blocks 5 can be changed, thereby adjusting the range of tightening between the first and second semicircular rings 3 and 4 and the tightness of the tightening.

[0030] A plurality of limiting holes 12 are formed in the first semicircular ring 3 and the second semicircular ring 4, respectively, penetrating the inner walls of the first semicircular ring 3 and the second semicircular ring 4. A fastening bolt 7 is connected to each limiting hole 12. The limiting holes 12 and the fastening bolts 7 allow the fastening bolts 7 to be screwed inward after the fastening ring 1 is wrapped around the coupling, thereby further strengthening the fastening ring 1's fixation on the coupling and preventing the fastening ring 1 from sliding on the coupling surface.

[0031] Both stop rods 2 are movable along the length of the side sleeves 8. Fixing bolts 9 are attached to the two side sleeves 8 to secure the stop rods 2. The stop rods 2 can be moved within the side sleeves 8 and adjusted to a suitable length based on the coupling's surroundings. The adjusted stop rods 2 are then secured with fixing bolts 9 to facilitate their function as a stop.

[0032] The bottoms of the two stop rods 2 are respectively fixedly connected with fixed base plates 10, and the two fixed base plates 10 are respectively formed with fixing holes 11. Through the fixing base plates 10 and the fixing holes 11, the stop rods 2 can be connected and fixed to the ground as needed to enhance the anti-rotation effect.

[0033] The outer sides of the first semicircular ring 3 and the second semicircular ring 4 are both provided with reinforcing plates 13. By being provided on the outer side of the fastening ring 1, its use strength can be improved, making it not easy to break or be damaged.

[0034] The inner sides of the first semicircular ring 3 and the second semicircular ring 4 are both provided with a wear-resistant layer 14. The material of the wear-resistant layer 14 is ceramic wear-resistant material. By providing the wear-resistant layer 14 inside the fastening ring 1, the wear resistance after connection with the coupling can be improved, and the wear generated after tight connection can be reduced.

[0035] The two stop rods 2 are made of steel pipes, and the first semicircular ring 3 and the second semicircular ring 4 are made of stainless steel.

[0036] The lower surface of the fixed base plate 10 is provided with anti-slip grooves. The anti-slip grooves can improve the friction between the fixed base plate 10 and the ground. The entire coupling anti-rotation stop device has a simple structure, is convenient and practical, and has a low production cost, which allows for mass production and use. At the same time, multiple fastening rings 1 of different sizes can be produced as needed to adapt to couplings of different sizes.

[0037] Working principle: The fastening ring is placed on the coupling, and the size of the fastening ring and the tightness of the connection with the coupling can be changed under the action of the connecting component, so as to make fine adjustments according to the size of different couplings. At the same time, retractable and adjustable stop rods are provided on both sides of the fastening ring, which can be used in contact with the ground after the fastening ring fixes the coupling, so as to prevent the coupling from rotating and realize the anti-rotation stop function. The reinforcing plate provided on the outside of the fastening ring can improve its use strength and make it less likely to break and be damaged. The wear-resistant layer provided on the inside of the fastening ring can improve the wear resistance after connection with the coupling and reduce the wear generated after the tight connection. The entire coupling anti-rotation stop device has a simple structure, is convenient and practical, and has a low production cost, so it can be produced and used in large quantities. At the same time, multiple fastening rings of different sizes can be produced as needed to adapt to couplings of different sizes.
