[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a portable pressure regulating box valve lever, which has the following advantages:

[0015] 1. By designing a limiting seat that can rotate within a groove and has various types of limiting grooves on its circumference, this invention significantly improves the versatility and ease of operation of the valve lever. Operators can flexibly rotate the limiting seat to the optimal working angle according to the operational needs of different valve positions and models, and select a limiting groove that matches the valve interface for engagement. This design effectively solves the problems of inconvenient operation and poor adaptability of traditional valve levers in confined or special angular spaces, greatly improving the tool's practicality and adaptability to different working conditions.

[0016] 2. Through the design of the locking rods, the double locking rods, together with the locking plate, adjusting rod, and L-shaped plate with anti-slip rubber sleeve, constitute a stable and reliable locking system. After the limit seat is rotated to the required angle, simply turn the adjusting rod to drive the locking plate to simultaneously insert the two locking rods into the corresponding locking holes on the circumference of the limit seat, achieving multi-point secure locking. This mechanism effectively overcomes the defects of easy loosening and poor stability after angle adjustment, ensuring that the angle remains unchanged during force application, thus guaranteeing the safety and efficiency of the operation.

[0017] 3. The extension plate design, featuring an adjustment groove at the lower end of the wrench body, a rotatable extension plate, and a locking mechanism with limiting rods, allows for flexible adjustment of the handheld end length. The operator can rotate the extension plate out from the adjustment groove and then tighten the limiting rods on both sides, allowing them to pass through the through holes on the rotating shaft, thus securely locking the extension plate in its extended state. Anti-slip protrusions at the front and rear ends of the extension plate further enhance grip stability. Attached Figure Description

[0027] Please see Figures 1-4 A portable pressure regulating box valve wrench includes a wrench body 1. A groove 2 is formed on the upper end face of the wrench body 1. A limiting seat 3 is rotatably provided inside the groove 2. A limiting groove 4 is formed on the outer end face of the limiting seat 3. Multiple limiting grooves 4 are arranged in the circumferential direction relative to the limiting seat 3. The inner grooves of the multiple limiting grooves 4 are arranged with different models. A through groove 5 is formed on the wrench body 1. A locking rod 6 is provided through the through groove 5 and the groove 2. Two locking rods 6 are symmetrically arranged. A locking hole 7 is formed on the outer end face of the limiting seat 3 corresponding to the two locking rods 6. Multiple locking holes 7 are arranged in the circumferential direction relative to the limiting seat 3. A locking plate 8 is connected to the bottom end of the two locking rods 6. The locking plate 8 is slidably arranged relative to the through groove 5.

[0028] In this embodiment, the limiting seat 3 rotates relative to the groove 2 for adjustment. The appropriate limiting groove 4 is selected according to the position and angle of the valve to be opened or closed. The position of the required limiting groove 4 is adjusted. After the initial rotation adjustment, the locking plate 8 slides relative to the through groove 5, which drives the locking rod 6 to slide upward and insert into the inner side of the groove 2. The locking rod 6 is inserted into a suitable set of locking holes 7. The angle adjustment achieves stable locking, which facilitates the opening and closing operation of valves in different positions.

[0029] More specifically, the hand-held wrench body 1 is inserted into the pressure regulating box to control the opening and closing of the valve at the appropriate position. The limit groove 4 is inserted to limit the valve of the appropriate model. The wrench body 1 drives the limit seat 3 to rotate, thereby realizing the adjustment operation.

[0030] Please see Figures 1-4 As one embodiment of the rotational locking: an adjusting rod 9 is rotatably provided inside the through groove 5, and an adjusting hole 10 is provided on the locking plate 8 corresponding to the adjusting rod 9. The adjusting rod 9 and the adjusting hole 10 are threadedly connected. A rotating ring 11 is provided at the bottom of the outer end face of the adjusting rod 9. Anti-slip grooves 12 are provided around the outer end face of the rotating ring 11. L-shaped plates 13 are hinged to the left and right sides of the front end face of the wrench body 1 corresponding to the through groove 5 and the locking plate 8. Anti-slip rubber sleeves 14 are provided on both L-shaped plates 13.

[0031] Specifically, after the limit seat 3 is rotated and adjusted to a suitable angle, the rotating ring 11 with anti-slip groove 12 is held by hand. The rotating ring 11 drives the adjusting rod 9 to rotate. The adjusting rod 9 and the adjusting hole 10 are threaded together to realize the overall sliding drive of the locking plate 8 and the locking rod 6. After initial locking, the L-shaped plate 13 is hinged and inserted into the through groove 5. The L-shaped plate 13 with anti-slip rubber sleeve 14 cooperates with the rotating ring 11 and the locking plate 8 in the through groove 5 to prevent slipping and further tighten the locking state.

[0032] Please see Figures 1-3 and Figure 5 As one embodiment of the extended wrench: an adjustment groove 15 is provided on the lower end face of the wrench body 1, and an extension plate 16 is rotatably provided inside the adjustment groove 15. A rotating shaft 17 is provided on both the left and right ends of the extension plate 16. A rotating groove 18 is provided on the inner wall of both the left and right ends of the adjustment groove 15 corresponding to the rotating shaft 17. Limiting holes 19 are provided on both the left and right sides of the lower end face of the wrench body 1 corresponding to the rotating groove 18. A limiting rod 20 is provided inside each of the two limiting holes 19. The limiting rod 20 and the limiting hole 19 are threadedly connected. A through hole 21 is provided on each of the two rotating shafts 17 corresponding to the limiting rod 20. Anti-slip protrusions 22 are provided on both the front and rear ends of the extension plate 16. Multiple anti-slip protrusions 22 are provided at intervals.

[0033] Specifically, the extension plate 16 is retracted and extended relative to the adjustment groove 15, and the rotating shaft 17 is rotated and adjusted relative to the rotating groove 18. After rotating to open or retract, the limiting rod 20 is rotated. The limiting rod 20 and the limiting hole 19 are threaded together. The limiting rod 20 is inserted into the through hole 21 of the rotating shaft 17. The through hole 21 is vertically set in the open or retracted state to lock the open or retracted state, which facilitates the extension adjustment of the hand end. When operating by hand, the anti-slip protrusion 22 ensures a stable and anti-slip grip.

[0034] In summary, the overall equipment is in use:

[0035] When the limit seat 3 is in the adjustment state, the limit seat 3 rotates relative to the groove 2 for adjustment. Select the appropriate limit groove 4 according to the valve model to be operated, and rotate the limit groove 4 to the angle that is convenient for operation according to the valve position. After the angle adjustment is completed, rotate the rotating ring 11 with the anti-slip groove 12. The rotating ring 11 drives the adjusting rod 9 to rotate. The adjusting rod 9 and the adjusting hole 10 are threaded together, so that the locking plate 8 and the locking rod 6 slide upward relative to the through groove 5. The locking rod 6 is inserted upward into the groove 2, and a set of locking holes 7 corresponding to the downward position after the rotation adjustment are inserted to lock the angle adjustment.

[0036] When the locking is tightened, the adjusting rod 9 drives the locking plate 8 to slide. After the locking plate 8 slides to the uppermost position, the L-shaped plate 13 with anti-slip rubber sleeve 14 is hinged into the through groove 5. The L-shaped plate 13 with anti-slip rubber sleeve 14 and the locking plates 8 and rotating ring 11 on the upper and lower sides of the through groove 5 cooperate to prevent slipping and lock together, ensuring the locking effect and ensuring stability during operation.

[0037] When in handheld adjustment mode, to adjust the opening and closing, first rotate the limit rod 20. The limit rod 20 and the limit hole 19 are threaded together, and the limit rod 20 is pulled out from the through hole 21. The extension plate 16 rotates relative to the adjustment groove 15, and the rotating shaft 17 rotates relative to the rotating groove 18, realizing the rotation opening or retraction adjustment. After the adjustment is completed, rotate the limit rod 20 in the opposite direction. The limit rod 20 and the limit hole 19 are threaded together and inserted into the corresponding through hole 21 to ensure that the opening and closing state is locked. When operating the wrench body 1, hold the extension plate 16 with the anti-slip protrusion 22 to perform the opening and closing adjustment operation.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
