Description

Technical Field

[0001] The utility model relates to the technical field of valve control, and particularly relates to a two-way control mechanism for a valve unit. Background Art

[0002] The valve block is a key component of an integrated hydraulic system. It is not only a carrier for mounting other hydraulic components but also a channel body for connecting their oil circuits. The valve block body generally has a cuboid shape. Installation holes, oil passage holes, connection holes, etc. related to hydraulic valves are distributed on the valve block. And the control of the valve block body is similar to that of a conventional hydraulic valve. According to the driving method, it can be divided into automatic valves, power-driven valves, and manual valves.

[0003] For some valve blocks that need to be manually controlled, since they do not have a single oil circuit or they have multiple functions, such as integrating pressure regulation and commutation functions at the same time, it is necessary to set multiple control components such as handle rockers on the valve block to control the spool components of the oil circuits corresponding to the functions to be realized. When multiple control components are fixed on the valve block, they will occupy a large area of the valve block, affecting the appearance, and multiple control components need to be operated simultaneously when realizing the corresponding functions, resulting in low efficiency. Content of the Utility Model

[0004] I. Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a two-way control mechanism for a valve unit, which can integrate two control components to realize that one control component controls the functions of two oil circuits, thereby improving the control efficiency of the functions of the valve block.

[0006] II. Specific Technical Solutions

[0007] A two-way control mechanism for a valve unit includes a frame, a control handle, and a valve unit. The valve unit is arranged on one side of the frame. An installation seat is arranged on the frame. A rotating seat is horizontally rotatably arranged on the side of the installation seat close to the valve unit. The bottom of the control handle is vertically rotatably connected to the rotating seat through a sleeve. A first control component is fixedly arranged on one side of the rotating seat. A second control component is fixedly arranged on the sleeve. The first control component and the second control component are respectively connected to the first control end and the second control end of the valve unit.

[0008] Implementation Principle, Working Principle:

[0009] In this solution, the control handle and the valve unit are installed on the frame. Among them, an installation seat is provided at the upper end of the frame. The rotating seat is installed on the installation seat and can rotate horizontally. The bottom of the control handle can rotate vertically on the rotating seat. A first control component and a second control component are respectively installed on the rotating seat and the sleeve of the control handle. And the first control component and the second control component are respectively connected to the first control end and the second control end of the valve unit.

[0010] In specific applications, the control handle can rotate in the horizontal and vertical directions. When the control handle rotates horizontally, it drives the rotating seat to rotate on the mounting seat, thereby enabling the first control member to drive the valve core assembly corresponding to the first control end to operate; when the control handle rotates vertically, it drives the second control member through the sleeve to drive the valve core assembly corresponding to the second control end to work, realizing the two-way control of the valve unit.

[0011] Preferably: The mounting seat includes a bushing, and one end of the rotating seat is provided with a connecting shaft that cooperates with the bushing; in this preference, the connecting shaft and the bushing cooperate, enabling the rotating seat to rotate horizontally with the first control member through the cooperation of the bushing and the connecting shaft; among them, the connecting shaft and the bushing can be completed through bearings, thereby avoiding the rotating seat from slipping out of the bushing.

[0012] Preferably: The other end of the rotating seat is provided with a U-shaped member, the bottom of the U-shaped member is fixedly connected to the connecting shaft, and mounting holes are symmetrically opened on the U-shaped member; the sleeve is rotationally connected to the mounting holes through a pin shaft; in this preference: the second control member is arranged on the sleeve, and the sleeve is connected to the mounting holes of the U-shaped member through a pin shaft. The advantage of this is that the second control member rotates vertically on the U-shaped member following the sleeve, and the rotation directions of the first control member and the second control member do not affect each other.

[0013] Preferably: One end of the opening of the U-shaped member is fixedly connected to the first control member, the first control member is a mounting ear, a long circular hole is opened on the mounting ear, and the mounting ear is connected to the first control end through a dial pin; the first control end is a first control column; one end of the dial pin is fixedly connected to the upper end of the first control column, and the other end of the dial pin is bolted in the long circular hole;

[0014] In this preference: When the rotating seat rotates, it drives the mounting ear to rotate in the horizontal direction, thereby driving the second control column to lift and lower to complete the control of the corresponding valve core assembly. When the first control column lifts and lowers, the dial pin will also slide in the long circular hole at one end of the long circular hole, enabling the smooth lifting and lowering of the first control column.

[0015] Preferably: The U-shaped member and the mounting ear are integrally formed.

[0016] Preferably: The second control member is a spherical shaft, the other end of the spherical shaft is connected to the second control end, the second control end is a second control column that can lift and lower in the valve unit, and a long hole is provided at one end of the second control column connected to the spherical shaft; the diameter of the spherical shaft is smaller than the diameter of the long hole, and the other end of the spherical shaft is located in the long hole;

[0017] In this preferred embodiment, the spherical shaft is used as the second control member, and the spherical end of the spherical shaft is located within the long hole of the second control column. When the control handle drives rotation in the vertical direction, the spherical end of the spherical shaft will move along the axial direction of the long hole, thereby driving the second control column to rise or fall, achieving the control of the spool assembly by the second control column.

[0018] Preferably: The bottom of the control handle further includes a lever and a reinforcement member. The lever is used to drive the sleeve and the rotating seat to rotate in the vertical and horizontal directions respectively; both ends of the reinforcement member are connected to the spherical shaft and the lever respectively; In this preferred embodiment: A reinforcement member is provided on the control handle to increase the connection strength between the lever and the spherical shaft through this reinforcement member, and extend the service life of the lever.

[0019] The beneficial effects of this solution are:

[0020] 1. The levers of a control handle can be used to control the first control column and the second control column respectively, thereby achieving the control of two different spool assemblies; compared with the existing manually controlled valve blocks, the integration degree of its control members is higher, it occupies less space, has a better appearance, and more importantly, the operation is also simpler and more convenient.

[0021] 2. Through the rotational connection between the mounting seat and the rotating seat, and the rotational connection between the rotating seat and the control handle, the control handle can rotate in the horizontal and vertical directions, thereby achieving the rotation of the first control member and the second control member in the corresponding directions, with a clever concept.

DETAILED DESCRIPTION OF THE INVENTION

[0028] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0029] The embodiments are as Figures 1 - 4 shown:

[0030] A bidirectional control mechanism for a valve unit, which includes a frame 1, a control handle 2, and a valve unit 3. Specifically, the valve unit 2 is installed on one side of the frame 1, and the side of the frame 1 for installing the valve unit 3 is L-shaped, and the control handle 2 is located at the upper end of the frame 1;

[0031] During implementation, as Figure 1 , a mounting seat 101 is installed on the frame 1 by bolts or screws, and a bushing 102 is welded and fixed in the middle of the mounting seat 101; the bushing 102 is used to install a rotating seat 4. Specifically, the two ends of the rotating seat 4 are respectively a U-shaped part 403 and a connecting shaft 402 welded together, and the connecting shaft 402 is rotatably connected to the bushing 102 through a bearing; the advantage of this is that the U-shaped part 403 can rotate circumferentially around the bushing 102 following the rotating seat 4, and the connecting shaft 402 will not fall off from the rotating seat 4; during implementation, a first control member 401 is provided at any one end of the opening of the U-shaped part 403, and the first control member 401 can rotate circumferentially around the bushing 102 following the rotating seat 4, thereby driving the first control end 301 connected to the first control member 401.

[0032] During implementation, the first control member 401 is a mounting ear integrally formed at any one end of the opening of the U-shaped part, and a long circular hole 405 is opened on the mounting ear, and the length direction of the long circular hole 405 is perpendicular to the rotation direction of the mounting ear; during implementation, the first control end 301 is a first control column, and the first control column is arranged on the upper surface of the valve unit 3, and its lower end is connected to the corresponding valve core assembly inside the valve unit 3, and its lifting on the valve unit 3 can complete the control of the corresponding valve core assembly; specifically, a pin 406 is provided at the top of the first control column, one end of the pin 406 is fixed to the top of the first control column by a bolt, and the other end of the pin 406 is restricted at the long circular hole 405 by a bolt; when the first control member 401 rotates around the connecting shaft 402, the upper and lower ends of the long circular hole 405 will drive the first control end 301 to lift through the pin 406, and at the same time, the pin 406 will also slide in the long circular hole 405 to ensure the smooth lifting of the first control end 301.

[0033] During implementation, mounting holes 404 are symmetrically formed in the U-shaped part 403. A sleeve 201 is welded to the bottom of the control handle 2, and the sleeve 201 is rotatably connected to the two mounting holes 404 through a pin shaft. Specifically, a second control member 202 is welded to the middle of the sleeve 201. The second control member 202 is specifically a spherical shaft, and the spherical shaft is perpendicular to the sleeve 201. When the control handle 2 rotates around the mounting hole 404, the sleeve 201 and the spherical shaft will rotate simultaneously to drive the second control end 302. The second control end 302 is a second control column, which is arranged on the upper surface of the valve unit 3, and its lower end is connected to the corresponding valve core assembly inside the valve unit 3. Its lifting and lowering in the valve unit 3 can complete the control of the corresponding valve core assembly. Specifically, a long hole is formed at the top of the first control column, and the spherical shaft extends into the long hole. When the spherical shaft rotates, the part of the spherical shaft in the long hole will drive the second control column to lift and lower, and the contact point between the spherical shaft and the inner wall of the long hole will move along the axial direction of the long hole to ensure the smooth lifting and lowering of the second control column.

[0034] During implementation, as shown in the appendix Figure 2 , the bottom of the control handle 2 specifically includes a lever 203 and a reinforcing member 204. The reinforcing member 204 is specifically a reinforcing rib or a reinforcing block. When the reinforcing member 204 is a reinforcing rib, both ends of the reinforcing rib are respectively connected to the lever 203 and the spherical shaft to ensure the connection strength. When it is a reinforcing block, one end of it should be connected to the sleeve 201, the lever 203 and the spherical shaft.

[0035] The working principle and implementation method are as follows:

[0036] This solution realizes the control of two valve core assemblies through the independent rotation of a control handle 2 in two directions, and realizes two different functions of the valve unit 3. In this embodiment, the control of the two valve core assemblies is respectively realized by the lifting and lowering of the first control end 301 and the second control end 302 connected to them.

[0037] Regarding the second control end 302, it is driven by the second control member 202 of the control handle 2. Specifically, when the control handle 2 rotates axially along the connecting shaft 402 of the rotating seat 4, the spherical shaft in the long hole at the top of the second control end 302 will also rotate around the axis of the bushing 102, and the part of the spherical shaft in the long hole will slide to drive the second control member 202 to lift and lower smoothly, realizing the control of one valve core assembly.

[0038] Regarding the first control end 301, it is driven by the first control member 401, and the first control member 401 specifically rotates circumferentially around the bushing 102; when the lever 203 rotates around the axis of the bushing 102, the mounting ear also rotates, and the pin 406 inside it drives the first control end 301 (the first control column) to move up and down. When it moves up and down, one end of the pin 406 in the long circular hole 405 will move along the length direction of the long circular hole, enabling the smooth movement of the first control column up and down; when the lever 203 rotates, the first control end 301 and the second control end 302 can be driven with a relatively small rotation amplitude.

[0039] In summary, the lever 203 of a control handle 2 can be used to control two spool assemblies respectively. Compared with the existing manually controlled valve unit, the integration degree of its control members is higher, it occupies less space, has a better appearance, and more importantly, the operation is simpler and more convenient.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims.
