DETAILED DESCRIPTION
[0019] The following will be combined with specific embodiments and attached Figure 1-4 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0020] The utility model provides an auxiliary tool for opening and closing valves (such as Figure 1As shown), it includes a bearing seat 1 and a two-way retractable ratchet wrench 2. The two-way retractable ratchet handle 2 is a known mature technology product on the existing market. Its locking direction can be selected. At the same time, the length of the wrench can be adjusted within a certain range. The adjustable length of the wrench can realize the adjustment of the size of the rotating force arm. The bearing seat 1 is circular. In this specific embodiment, the bearing seat 1 can be a circular plate. Three groups of hanging components are arranged on the outer wall of the bearing seat 1 at equal intervals along its circumferential direction. Each group of the hanging components includes a connecting rod 3 and a hook 4. One end of the connecting rod 3 is connected to the bearing seat 1. The hook 4 is arranged on the connecting rod 3. The hook 4 can move up and down, forward and backward and rotate relative to the connecting rod 3. The hook 4 can move up and down and forward and backward relative to the connecting rod 3, which is conducive to operating the hook 4 so that it can be smoothly hung on the spokes (spokes) corresponding to the handwheel. It is a connecting rod between the outer ring of the handwheel and the central tube set in the middle. Most handwheels have three spokes, and a few handwheels have four or five spokes. The hook 4 rotates relative to the connecting rod 3, which makes it easy to change the hanging direction of the hook 4 according to the rotation direction of the handwheel, so as to smoothly realize the clockwise or counterclockwise rotation drive of the handwheel later. A first plug-in slot 11 corresponding to the plug-in rod 21 of the bidirectional retractable ratchet wrench 2 is set on the bearing seat 1. When the plug-in rod 21 is inserted into the first plug-in slot 11, the rotation drive of the bearing seat 1 is realized by rotating the bidirectional retractable ratchet wrench 2. A handle 22 is hingedly set at the bottom of the fixed rod of the bidirectional retractable ratchet wrench 2. The handle 22 can realize the one-handed high-speed rotation of the bidirectional retractable ratchet wrench 2, so that in actual application, the high-speed rotation of the corresponding handwheel can be realized, and then the high-speed opening or closing of the handwheel can be realized. During the actual operation, each hook 4 is first hung on the spoke corresponding to the handwheel, and then the plug-in rod 21 of the bidirectional telescopic ratchet wrench 2 is inserted into the first plug-in slot 11. After the plug-in is completed and the length of the bidirectional telescopic ratchet wrench 2 is adjusted, the handwheel can be rotated by rotating the bidirectional telescopic ratchet wrench 2.
[0021] In order to facilitate the three connecting rods 3 on the supporting seat 1 to not only adapt to the handwheels with three spokes, but also to a certain extent better adapt to the handwheels with four or five spokes, an inverted trapezoidal groove 12 corresponding to the bottom of the connecting rod 3 is provided on the supporting seat 1, and the bottom of the connecting rod 3 is hingedly arranged in the inverted trapezoidal groove 12 and the connecting rod 3 can swing in the radial plane of the supporting seat 1. The connecting rod 3 can swing, so that in actual application, it can be adjusted to a certain angle of swing to make it as close as possible to the adjacent spokes, so as to facilitate the hook 4 thereon to be smoothly hung on the spoke.
[0022] On the basis of the above embodiment, in order to facilitate the up and down sliding adjustment of the hook 4 on the connecting rod 3, an adjusting slot 31 is provided on the connecting rod 3, and the adjusting slot 31 passes through the connecting rod 3 front and back. Further, the hook 4 includes a hook head 41, and the hook head 41 is an arc-shaped hook structure, which is used to be hung on the spokes of the hand wheel. A hanging rod 42 is provided at the front end of the hook head 41, and the hanging rod 42 is sleeved in the corresponding adjusting slot 31. A limiting plate 421 is provided at the front and rear of the hanging rod 42. The limiting effect of the two limiting plates 421 can effectively prevent the hanging rod 42 from sliding out of the adjusting slot 31. A ∩-shaped plate 422 is provided on the limiting plate 421 located at the front of the hanging rod 42, and a T-shaped rod 411 is provided at the rear of the hook head 41. The T-shaped rod 411 is rotatably sleeved on the ∩-shaped plate 4 22, the hook head 41 can achieve 360-degree rotation using the T-shaped rod 411, and then the hand wheel can be smoothly rotated clockwise or counterclockwise by changing the direction of the hook head 41. Under normal circumstances, the hook head 41 is located in front of the hand wheel spoke. When the hand wheel is rotated clockwise, the hook head 41 is hung on the left side of the spoke, and when the hand wheel is rotated counterclockwise, the hook head 41 is hung on the right side of the spoke. When the hook head 41 is hung on the spoke, in order to prevent the hook head 41 from falling off, a spring 43 is sleeved on the hanging rod 42, and the spring 43 is clamped between the limit plate 421 at the front of the hanging rod 42 and the connecting rod 3. The spring 43 can apply a forward pulling force to the hook head 41, thereby facilitating the stable hanging of the hook head 41 on the spoke. In order to prevent the hanging rod 42 from rotating in the adjusting slot 31, the hanging rod 42 is a square rod.
[0023] In actual application, some hand wheels are located very close to the wall, which results in the inability to effectively realize the continuous full-circle rotation of the bidirectional retractable ratchet wrench 2 when the hand wheel is rotated using the utility model. In order to facilitate the use of the utility model to smoothly realize the rotational drive of the hand wheel close to the wall, three equally spaced connecting columns 5 are fixedly provided on the front side wall of the bearing seat 1, and a connecting plate 6 is fixedly provided at the front end of the three connecting columns 5. A second plug-in groove 61 corresponding to the plug-in rod 21 of the bidirectional retractable ratchet wrench 2 is provided in the middle of the connecting plate 6. The second plug-in groove 61 is coaxially distributed with the bearing seat 1. When the plug-in rod 21 is inserted into the second plug-in groove 61, the bearing seat 1 can be driven to rotate by repeatedly rotating the bidirectional retractable ratchet wrench 2, which can then drive the corresponding hand wheel to rotate.
[0024] In actual applications, a threaded rod of a certain length will extend from the middle of some handwheels. In order to facilitate the support base 1 to be close to the handwheel, a circular through hole 13 is set in the middle of the support base 1. When the utility model is installed, the threaded rod is installed in the circular through hole 13, so that the threaded rod will not affect the installation of the support base 1.
[0025] The application operation steps of an embodiment of the utility model are as follows: the first step is to hold the bearing seat 1, and first adjust the position of each connecting rod 3 according to the distribution of the spokes of the handwheel that needs to be opened, so that each connecting rod 3 is as close to the corresponding spoke as possible; the second step is to hang each hook head 41 on one side of the corresponding spoke, and when hanging the hook head 41, make the hook head 4 as close to the circular ring position of the handwheel as possible; the third step is to adjust the length of the two-way telescopic ratchet wrench 2 after the hanging is completed, so that its length is as long as possible within the operable range, and then insert the plug-in rod 21 of the two-way telescopic ratchet wrench 2 into the first plug-in slot 11. After the plug-in is completed, the handwheel can be finally driven to rotate by applying a thrust to the two-way telescopic ratchet wrench 2.
[0026] In the present utility model, "upper", "lower", "front", "back", "left" and "right" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.
[0027] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
[0028] The above description in combination with the accompanying drawings has detailed the preferred implementation modes and embodiments of the utility model, but the utility model is not limited to the above implementation modes and embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
