Description

Technical Field

[0001] This utility model belongs to the technical field of valve disassembly wrenches, specifically a pre-positioned valve disassembly wrench for property management. Background Technology

[0002] A pre-control valve is a valve installed in a piping system, located at the upstream end of the equipment or system. Its main function is to control fluid flow, opening, closing, or regulating flow. A property-specific pre-control valve removal wrench is a tool specifically designed for removing pre-control valves in a property's piping system. It allows for convenient and quick valve removal, facilitating maintenance, replacement, or inspection. Existing property-specific pre-control valve removal wrenches generally adopt a one-piece design, typically with one or more holes of various sizes. Because the hole sizes are difficult to change, they can generally only remove a limited number of bolt sizes, thus limiting their application range. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a property-specific pre-valve disassembly wrench, which solves the problem that existing property-specific pre-valve disassembly wrenches generally adopt an integrated design and have one or more holes of different sizes. Since the size of the holes is difficult to change, they can generally only disassemble a small number of bolt sizes, thus limiting their scope of application.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pre-valve disassembly wrench for property management, comprising a housing, two connecting shells fixedly connected to the housing, two movable rods slidably connected through the connecting shells, springs sleeved on the movable rods, a connecting plate fixedly connected to one end of each movable rod, a movable plate fixedly connected to the other end of each movable rod, an inclined block fixedly connected to the movable plate, two sliders fixedly connected to the top of the movable plate, and a moving plate fixedly connected to the top of each slider.

[0005] The top of the housing is rotatably connected to a turntable via a pivot. The top of the turntable is rotatably connected to two connecting rods via a pivot. One end of each connecting rod is rotatably connected to the top of a movable plate via a pivot. An installation plate is provided inside the housing. A wrench head is fixedly connected to one side of the installation plate. A limit groove is provided on the installation plate at the position corresponding to the inclined block.

[0006] As a further embodiment of this utility model: one end of the spring is fixedly connected to the movable plate, and the other end of the spring is fixedly connected to the inside of the connecting shell.

[0007] As a further embodiment of this utility model: a groove is provided on the connecting shell at the position corresponding to the slider, and the slider is slidably connected inside the groove.

[0008] As a further embodiment of this utility model: an outer shell is fixedly connected to the top of the housing, the turntable is located inside the outer shell, and a rotating column is fixedly connected to the top of the turntable.

[0009] As a further embodiment of this utility model: a knob is fixedly connected to the top of the rotating column, and the rotating column is rotatably connected to the outer shell through a bearing.

[0010] As a further embodiment of this utility model: a connecting strip is fixedly connected to one side of the housing, and a box is sleeved on the outside of the connecting strip, with two screws threadedly connected to the box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This property-specific pre-valve disassembly wrench, through the setting of a limit groove, inclined block, spring, turntable, connecting rod and moving plate, when it is necessary to disassemble the wrench head, turning the knob drives the rotating column and turntable to rotate. As the turntable rotates, the turntable will push the moving plate to move through the connecting rod. The moving plate will drive the slider, movable plate and inclined block to move. At the same time, the two inclined blocks will move away from each other and disengage from the inside of the limit groove, thereby releasing the fixed state of the mounting plate. At this time, the wrench head can be disassembled. When it is necessary to install the wrench head, the mounting plate is placed inside the housing. When the mounting plate contacts the inclined surface of the inclined block, the mounting plate pushes the inclined block away, causing the inclined block to move the movable plate. The movable plate compresses the spring. When the limiting groove moves to the inclined block, the inclined block loses the support of the mounting plate, causing the spring to reset and push the movable plate and the inclined block to move. This brings the two inclined blocks closer together and inserts them into the limiting groove to fix the mounting plate and the wrench head, completing the installation of the wrench head. This wrench adopts a modular design, which facilitates the disassembly and installation of the wrench head. It allows the wrench head to be replaced with a matching wrench head according to the bolt type, expanding its application range.

[0012] 2. This property-specific pre-valve disassembly wrench, consisting of a connecting bar, housing, and screw, allows for easy adjustment of the connecting bar's extension length. Loosening the screw releases the connecting bar from its fixed position, allowing it to slide freely within the housing. Once the extension length is adjusted appropriately, tightening the screw secures the connecting bar. Lengthening the connecting bar increases the lever arm, making it easier to tighten large or tightly secured bolts; shortening the connecting bar reduces the lever arm, decreasing torque output and allowing for more precise and controllable operation. It is suitable for tightening small or easily damaged bolts. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-5 As shown, this utility model provides a technical solution: a pre-valve disassembly wrench for property management, including a housing 1, two connecting shells 6 fixedly connected to the housing 1, and two movable rods 15 slidably connected through the connecting shells 6. Because of the movable rods 15, when the movable plate 18 moves, the movable rods 15 will slide on the connecting shells 6. The movable rods 15 can play the role of limiting and guiding the movable plate 18, improving the stability and accuracy of the movement of the movable plate 18. A spring 16 is sleeved on the movable rod 15. One end of the two movable rods 15 is fixedly connected to a connecting plate 17, one end of the spring 16 is fixedly connected to the movable plate 18, and the other end of the spring 16 is fixedly connected to the inside of the connecting shell 6.

[0021] Two movable rods 15 are fixedly connected to movable plates 18 at their other ends. An inclined block 19 is fixedly connected to the movable plate 18. The inclined design of the inclined block 19 makes it easy for the mounting plate 13 to push the inclined block 19, thereby ensuring the normal operation of subsequent work. Two sliders 20 are fixedly connected to the top of the movable plate 18. A movable plate 11 is fixedly connected to the top of the two sliders 20. A turntable 7 is rotatably connected to the top of the housing 1 via a rotating shaft. Because of the turntable 7, when the turntable 7 rotates, it can push the two movable plates 11 to move synchronously and move away from each other through the connecting rod 10, so as to realize that the two inclined blocks 19 are synchronously disengaged from the inside of the limiting groove 14. A sliding groove 12 is opened on the connecting shell 6 at the position corresponding to the slider 20. The slider 20 is slidably connected inside the sliding groove 12.

[0022] Two connecting rods 10 are rotatably connected to the top of the turntable 7 via a rotating shaft. One end of the connecting rod 10 is rotatably connected to the top of the moving plate 11 via a rotating shaft. An installation plate 13 is provided inside the housing 1. A wrench head 5 is fixedly connected to one side of the installation plate 13. An outer shell 2 is fixedly connected to the top of the housing 1. The turntable 7 is located inside the outer shell 2. A rotating column 8 is fixedly connected to the top of the turntable 7.

[0023] A limiting groove 14 is provided on the mounting plate 13 at the position corresponding to the inclined block 19. A knob 9 is fixedly connected to the top of the rotating column 8. The rotating column 8 is rotatably connected to the outer shell 2 through a bearing. A connecting strip 3 is fixedly connected to one side of the outer shell 1. A box 4 is fitted over the connecting strip 3. Two screws 21 are threaded on the box 4. Because of the screws 21, tightening the screws 21 can fix the connecting strip 3, thereby ensuring the stability of the position of the connecting strip 3 and ensuring the normal operation of the wrench.

[0024] The working principle of this utility model is as follows: When it is necessary to adjust the extension length of the connecting strip 3, loosen the screw 21 to release the fixed state of the connecting strip 3. At this time, the connecting strip 3 is in an active state and can slide freely inside the box 4. When the extension length of the connecting strip 3 is adjusted appropriately, tighten the screw 21 to fix the connecting strip 3. When it is necessary to disassemble the wrench head 5, turn the knob 9 to drive the rotating column 8 and the turntable 7 to rotate. As the turntable 7 rotates, the turntable 7 will push the moving plate 11 to move through the connecting rod 10. The moving plate 11 will drive the slider 20, the movable plate 18 and the inclined block 19 to move. At the same time, the two inclined blocks 19 will move away from each other and disengage from the inside of the limiting groove 14, thereby releasing the fixed state of the mounting plate 13. At this time, the wrench head 5 can be disassembled.

[0025] When the wrench head 5 needs to be installed, the mounting plate 13 is placed inside the housing 1. When the mounting plate 13 contacts the inclined surface of the inclined block 19, the mounting plate 13 will push the inclined block 19 away. The inclined block 19 will drive the movable plate 18 to move, and the movable plate 18 will compress the spring 16. When the limiting groove 14 moves to the inclined block 19, the inclined block 19 loses the support of the mounting plate 13, which will cause the spring 16 to reset and push the movable plate 18 and the inclined block 19 to move. This will cause the two inclined blocks 19 to approach each other and insert into the inside of the limiting groove 14 to fix the mounting plate 13 and the wrench head 5, thus completing the installation of the wrench head 5.
