Description

Technical Field

[0001] The utility model relates to the technical field of valve accessories, in particular to a fastening device. Background Art

[0002] Valves are very common components in ship's engine room. To avoid obstructing people walking on the ship's platform, valves must be installed flush with the iron plate. This makes operation difficult. When people need to open or close the valve, they have to stand on the iron plate to operate the valve because the valve is flush with the iron plate, which is very inconvenient.

[0003] Patent publication number CN208331411U discloses a valve fastening device. The device is configured by providing a rotating handle, a first rotating shaft, a second rotating shaft, a fixing fork, and a limiting hole. The handle is rotated, and the L-shaped fixing fork is used to turn the valve's handwheel. After use, the device can be placed next to the valve for standby use. This solves the problem of difficulty opening and closing valves arranged horizontally with the iron plate, while also not affecting the normal movement of cabin personnel. However, because the device is not fixedly connected to the valve, it can be easily lost if placed next to the valve when not in use. If it were directly fixedly connected to the valve's handwheel, the rotating shaft at the top would extend beyond the iron plate, thus requiring further improvement. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a fastening device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a fastening device, including a cross bar, two sleeves are slidably connected to the surfaces of both ends of the cross bar, and the bottom ends of the two sleeves are installed with a fixing assembly, and the sleeve is fixedly connected to the handwheel of the valve through the fixing assembly, two first side plates are fixed to the middle part of the upper surface of the cross bar, and a vertical arm is rotatably connected between the two first side plates through an axle rod, a clamping hole is provided at the top of any one of the first side plates, and a clamping assembly for fixing the vertical arm is provided on the side of the vertical arm close to the clamping hole, two second side plates are fixed to the side surface of the top of the vertical arm, and a cross arm is rotatably connected between the two second side plates through an axle rod.

[0006] Furthermore, a first locking bolt passes through and is threadedly connected to the side wall of the sliding sleeve.

[0022] like Figure 1-Figure 3 As shown, it relates to a fastening device, including a cross bar 1, two sleeves 2 are slidably connected to the surfaces of both ends of the cross bar 1, and a fixing component 3 is installed at the bottom end of the two sleeves 2, and the sleeve 2 is fixedly connected to the handwheel of the valve through the fixing component 3, and two first side plates 4 are fixed to the middle of the upper surface of the cross bar 1, and a vertical arm 5 is rotatably connected between the two first side plates 4 through an axis rod. A clamping hole 41 is provided at the top of any first side plate 4, and a clamping component 6 for fixing the vertical arm 5 is provided on the side of the vertical arm 5 near the clamping hole 41, and two second side plates 7 are fixed to the side of the top of the vertical arm 5, and a cross arm 8 is rotatably connected between the two second side plates 7 through an axis rod.

[0023] A first locking bolt 21 passes through the side wall of the sliding sleeve 2 and is threadedly connected thereto.

[0024] The two sleeves 2 can move along the cross bar 1, and tightening the first locking bolt 21 can fix the sleeves 2, so that the distance between the two fixing components 3 can be adjusted according to the size of the valve handwheel, so that the two fixing components 3 can be just stuck on the handwheel.

[0025] Both ends of the crossbar 1 are fixedly connected with side end plates 12 .

[0026] The side end plate 12 can prevent the sliding sleeve 2 from being separated from the cross bar 1 when moving along the cross bar 1 .

[0027] The fixing assembly 3 includes a vertical rod 31 fixed to the lower surface of the sliding sleeve 2, and the bottom end of the vertical rod 31 is fixedly connected to a U-shaped plate 32, and a circular slot is opened inside the bottom end of the U-shaped plate 32. The side wall of the U-shaped plate 32 is penetrated and threadedly connected with a second locking bolt 33.

[0028] After the U-shaped plate 32 is clamped on the handwheel surface of the valve, the second locking bolt 33 can be tightened to fix it.

[0029] The clamping assembly 6 includes a groove 61 opened on the surface of the vertical arm 5. The inner wall of the groove 61 is fixedly connected to a spring 62. The other end of the spring 62 is fixedly connected to a clamping rod 63. The clamping rod 63 is clamped into the inside of the clamping hole 41 at one end away from the spring 62.

[0030] When the vertical arm 5 rotates to be perpendicular to the cross bar 1 , the spring 62 can push the clamping rod 63 into the clamping hole 41 on the first side plate 4 , so that the vertical arm 5 can be fixed in a vertical state.

[0031] A top baffle 9 is fixedly connected to the top of the two second side plates 7 .

[0032] When the cross arm 8 rotates upward between the two second side plates 7 , the top baffle 9 can play a limiting role.

[0033] A first magnet 10 is fixed to the top of the vertical arm 5 near the horizontal arm 8, and a second magnet 11 is fixedly connected to the lower surface of the top baffle 9. The horizontal arm 8 is made of iron.

[0034] When the horizontal arm 8 rotates to fit the vertical arm 5 , the first magnet 10 can attract the horizontal arm 8 to fix the horizontal arm 8 . When the horizontal arm 8 rotates to be perpendicular to the vertical arm 5 , the second magnet 11 can attract the horizontal arm 8 to fix the horizontal arm 8 .

[0035] Working principle: When installing the device, first slide the two sleeves 2 along the crossbar 1 and adjust the distance between the two fixing components 3. After the adjustment is completed, tighten the first locking bolt 21 to fix the sleeve 2. Then clamp the two U-shaped plates 32 on both sides of the valve handwheel, and then tighten the second locking bolt 33 to achieve a fixed connection with the valve handwheel. When the fastening device needs to be used, first squeeze the clamping rod 63 and rotate the vertical arm 5 until the vertical arm 5 is perpendicular to the crossbar 1. During this process, when the clamping rod 63 coincides with the clamping hole 41, the spring 62 pushes the clamping rod 63 into the clamping hole 41 to fix the vertical arm 5. Then, rotate the crossbar 8 to be perpendicular to the vertical arm 5. The crossbar 1 can be rotated by pulling the crossbar 8, thereby driving the valve handwheel to rotate. After use, first rotate the crossbar 8 to fit the vertical arm 5, then squeeze the clamping rod 63 to disengage from the clamping hole 41, and then rotate the vertical arm 5 to be parallel to the crossbar 1.
