Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a portable valve switching labor-saving device. Background Art

[0002] A valve is a device used to control the direction, pressure and flow of a fluid in a fluid system. It is a device that allows the medium in pipes and equipment to flow or stop and control its flow. In the chemical production process, manual control of the opening and closing of the valve is often required.

[0003] However, some valves have only one force point when they are opened and closed. In addition, due to the narrow working space, it is sometimes difficult for workers to operate the valves during opening and closing. It is laborious and there is also the risk that the valves will not be opened and closed properly. Therefore, a portable valve opening and closing labor-saving device is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a portable valve switch labor-saving device, which has the advantages of multiple force points and easy operation, and solves the problem that the valve switch has only one force point and is difficult to operate in a narrow space.

[0005] In order to achieve the above-mentioned purpose of multiple force points and easy operation, the utility model provides the following technical solutions: a portable valve switch labor-saving device, comprising a valve mechanism, the outside of which is connected to a handle mechanism;

[0006] The valve mechanism comprises a mounting rod, the outside of the mounting rod is connected to a limit block, the outside of the mounting rod is connected to a telescopic rod, and one side of the telescopic rod is connected to a socket;

[0007] The handle mechanism comprises a mounting tube, one side of the mounting tube is connected to a first handle, and the other side of the mounting tube is connected to a second handle.

[0008] Furthermore, the cross section of the mounting rod is hexagonal, the limit block is located on one side of the mounting rod, and the telescopic rod is located on the other side of the mounting rod.

[0009] Furthermore, the diameter of the limit block is larger than the diameter of the mounting rod, and the diameter of the telescopic rod is smaller than the diameter of the mounting rod.

[0010] Furthermore, the insert sleeve is located on a side of the telescopic rod away from the mounting rod, and a diameter of the insert sleeve is smaller than a diameter of the mounting rod.

[0011] Furthermore, the diameter of the installation tube is consistent with the diameter of the limiting block, the inner side of the installation tube is hexagonal, the installation tube is sleeved with the installation rod, and the first handle and the second handle are positioned oppositely.

[0012] Furthermore, the number of the handle mechanisms is three, and the first handles and the second handles of the three handle mechanisms are distributed in a cross shape.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The portable valve opening and closing labor-saving device has an installation tube that can be sleeved with the installation rod through a plug sleeve and a telescopic rod. When in use, the first handle and the second handle of the three handle mechanisms are arranged in a cross shape, and the installation tubes of the three handle mechanisms are all sleeved with the installation rod. In the case where the valve has only one handle, there are fewer stress points, making it difficult to open and close the valve and inconvenient to open and close the valve in place. By arranging three handle mechanisms, and the first and second handles of the three handle mechanisms are arranged in a cross shape, the valve can be opened and closed well manually no matter where it is, and the length of the telescopic rod is adjusted to a required length, so that the plug sleeve is inserted into the valve terminal, so that it is convenient to open and close the valve, and the problem of having only one stress point when opening and closing the valve is solved.

[0015] The portable valve opening and closing labor-saving device can adjust the length of the telescopic rod according to actual conditions when the space is small and it is difficult to open and close the valve, thereby adjusting the distance between the plug sleeve and the installation rod, so that the valve can be opened and closed well and the valve can be opened and closed in place, solving the problem of difficult operation in narrow space.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the case implementation, the limit block 102 is located on one side of the mounting rod 101, the telescopic rod 103 is located on the other side of the mounting rod 101, and the sleeve 104 is located on the side of the telescopic rod 103 away from the mounting rod 101, so the length of the telescopic rod 103 can be adjusted according to actual conditions, thereby adjusting the distance between the sleeve 104 and the mounting rod 101.

[0023] In the case implementation, the diameter of the limit block 102 is larger than the diameter of the mounting rod 101, the diameter of the telescopic rod 103 is smaller than the diameter of the mounting rod 101, the diameter of the sleeve 104 is smaller than the diameter of the mounting rod 101, the cross-section of the mounting rod 101 is hexagonal, the inner side of the mounting tube 201 is hexagonal, and the mounting tube 201 is sleeved with the mounting rod 101, so the mounting tube 201 can be sleeved with the mounting rod 101 through the sleeve 104 and the telescopic rod 103, and the diameter of the mounting tube 201 is consistent with the diameter of the limit block 102, so that the mounting tube 201 is limited by the limit block 102, which can prevent the handle mechanism 2 and the valve mechanism 1 from falling off during use.

[0024] In the case implementation, the positions of the first handle 202 and the second handle 203 are relative, and the number of the handle mechanisms 2 is three. When not in use, the first handles 202 of the three handle mechanisms 2 are overlapped, the second handles 203 of the three handle mechanisms 2 are overlapped, and the mounting tubes 201 of the three handle mechanisms 2 are all connected to the mounting rod 101, and the length of the telescopic rod 103 is adjusted to the shortest, so it has the advantage of portability. When in use, the first handles 202 and the second handles 203 of the three handle mechanisms 2 are distributed in a cross shape, and the mounting tubes 201 of the three handle mechanisms 2 are all connected to the mounting rod 101, and the length of the telescopic rod 103 is adjusted to the required length, and the socket 104 is connected to the valve terminal, so it is convenient to open and close the valve.

[0025] When implementing, follow these steps:

[0026] 1) First, the first handle 202 and the second handle 203 of the three handle mechanisms 2 are arranged in a cross shape;

[0027] 2) Then, the mounting tubes 201 of the three handle mechanisms 2 are sleeved with the mounting rods 101;

[0028] 3) Adjust the length of the telescopic rod 103 to the required length;

[0029] 4) Finally, the socket 104 is plugged into the valve terminal and the first handle 202 and the second handle 203 are rotated.

[0030] To sum up, in the portable valve switching labor-saving device, the mounting tube 201 can be sleeved with the mounting rod 101 through the plug sleeve 104 and the telescopic rod 103. When in use, the first handle 202 and the second handle 203 of the three handle mechanisms 2 are distributed in a cross shape, and the mounting tubes 201 of the three handle mechanisms 2 are all sleeved with the mounting rod 101. In the case where the valve has only one handle, there are fewer stress points, which makes it difficult to switch the valve, and it is not convenient to switch the valve in place. By setting three handle mechanisms 2, and the first handles 202 and the second handles 203 of the three handle mechanisms 2 are distributed in a cross shape, the valve can be opened and closed manually no matter where it is, and the length of the telescopic rod 103 is adjusted to the required length, and the plug sleeve 104 is plugged into the valve terminal, so that it is convenient to switch the valve, and the problem of having only one stress point when opening and closing the valve is solved.

[0031] Furthermore, when the space is small and it is difficult to open and close the valve, the length of the telescopic rod 103 can be adjusted according to the actual situation, thereby adjusting the distance between the sleeve 104 and the mounting rod 101, so that the valve can be opened and closed well and the valve can be opened and closed in place, solving the problem of difficult operation in narrow space.
