Description

Technical Field

[0001] This utility model relates to the field of pneumatic control components, and in particular to a modular valve island with an easy-to-install slide valve structure. Background Technology

[0002] A valve island is a modular pneumatic control unit that integrates multiple electrically controlled slide valves into one unit. It is widely used in automated production lines and mechanical equipment. Through centralized control, the valve island can effectively simplify the pneumatic circuit design and save installation space.

[0003] In the existing technology, the valve island body is installed with the base and equipment frame by bolt fastening. This installation method has revealed its shortcomings in actual operation. During installation, the staff needs to align the bolt holes one by one and use a wrench to tighten multiple bolts in sequence. The whole process is time-consuming, especially in situations where the space is small and the installation position is inconvenient, the operation is even more difficult.

[0004] Furthermore, this bolt fixing method has high requirements for installation accuracy and torque uniformity. If a bolt is not tightened or the force is uneven, it will loosen under the vibration environment generated by the long-term operation of the equipment, which will affect the stability of the entire valve island and the air circuit sealing. When it is necessary to replace and maintain the valve island, multiple bolts need to be loosened one by one. The disassembly process is also cumbersome, which reduces the efficiency of production and maintenance.

[0005] Therefore, this utility model proposes a modular valve island with an easy-to-install slide valve structure to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome and time-consuming installation process and insufficient connection reliability of the modular valve island with spool valve structure in the existing technology, this utility model aims to provide a modular valve island with spool valve structure that has been improved and can effectively solve the above problems and is easy to install.

[0007] This utility model provides a modular valve island with an easy-to-install slide valve structure, including a valve island body and an installation mechanism for installing the valve island body. The installation mechanism includes a mechanism block one, a position groove one is formed on the upper left side of the mechanism block one, an L-shaped locking block is slidably connected inside the position groove one, a spring piece one is fixedly connected to the lower right side of the L-shaped locking block, and a locking groove one is formed on the lower left side of the valve island body; in addition, a guide groove is formed on the lower right side of the valve island body, the upper end of the guide groove is connected to a rotating groove, a second position groove is formed on the upper right side of the mechanism block one, an automatic rotator is fixedly fixed inside the position groove two, and a locking plate is fixedly connected to the output end of the automatic rotator.

[0008] The valve island body is installed and fixed on the mechanism block one through the L-shaped locking block engaging with the first slot, and the locking plate being guided along the guide groove and rotated into the rotating groove by a double locking structure.

[0009] Furthermore, the other end of the spring piece can elastically deform and abut against the inner wall of the position groove. After installation and locking, the rebound force of the spring piece causes the L-shaped locking block and the locking plate to simultaneously apply a pre-tightening force to the valve island body, forming a stable and reliable connection.

[0010] Preferably, in order to seal the installation interface, a rubber groove is provided at the upper end of the second position groove, and a rubber ring is fixed inside the rubber groove. After installation, the rubber ring can fit tightly against the lower surface of the valve island body to prevent external impurities from entering.

[0011] Preferably, the modular valve island with easy-to-install slide valve structure further includes a rotating mechanism disposed below the mounting mechanism. The rotating mechanism includes a second mechanism block disposed at the lower end of the mechanism block. By adding the rotating mechanism, the entire valve island body is given the ability to adjust the installation direction.

[0012] Furthermore, in order to achieve smooth rotation, a connecting groove is provided in the middle of the lower end of the first mechanism block, and a rotating groove is provided in the middle of the upper end of the second mechanism block. A rotating shaft is fixed inside the connecting groove, and the lower end of the rotating shaft is rotatably connected to the middle of the inner side of the rotating groove. The central support of the rotating shaft ensures the smoothness of the rotation.

[0013] Furthermore, in order to achieve segmented positioning after rotation, a position groove three is circumferentially formed on the outer side of the connecting groove. A semi-circular locking block is slidably connected inside the position groove three. A locking groove two is circumferentially formed in the middle of the inner side of the mechanism block two for engaging with the semi-circular locking block. In addition, a spring piece two is fixedly connected to the upper end of the semi-circular locking block. The upper end of the spring piece two abuts against the inner wall of the top of the position groove three. Through the cooperation of the spring piece two and the semi-circular locking block with the locking groove two, step-by-step angle positioning is achieved.

[0014] Preferably, the L-shaped locking block includes a horizontal portion and a vertical portion that are perpendicular to each other. The horizontal portion is slidably received in the first position groove, and the vertical portion protrudes upward to engage with the first locking groove. This structure ensures that the L-shaped locking block can slide stably and provide reliable engagement.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problems of cumbersome valve island installation and poor connection reliability in the prior art by setting up a double locking installation mechanism consisting of an L-shaped card block and a rotatable card plate, and using the rebound force of the spring to pre-tighten the valve island body. It achieves the effects of quick positioning, tool-free installation, firm locking, vibration resistance and anti-loosening.

[0017] 2. This utility model solves the problem of fixed valve island installation direction and limited application scenarios in the prior art by adding a rotating mechanism with segmented positioning function below the installation mechanism. It achieves the effect of enabling the valve island to be flexibly adjusted at multiple angles and stably maintained at a preset angle, thereby enhancing the adaptability of equipment layout.

[0018] 3. This utility model, by modularly integrating the quick installation mechanism and the multi-angle rotation mechanism and setting a rubber ring for sealing, solves the problems of separation of valve island installation and adjustment functions, complex structure, and susceptibility to environmental pollution in the prior art, and achieves the effects of simplifying the installation and maintenance process, improving the convenience of operation and the long-term reliability of the system.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 5 This utility model provides a modular valve island with an easy-to-install slide valve structure, which aims to solve the problems of complex installation structure, cumbersome connection and positioning, and inability to adjust the direction after installation in the prior art.

[0029] Please refer to Figure 1 The modular valve island structure of the easy-to-install spool valve includes a valve island body 1, a mounting mechanism 2, and a rotating mechanism 3. The valve island body 1 is detachably fixed by the mounting mechanism 2, and the mounting mechanism 2 is supported by the rotating mechanism 3 and can rotate at multiple angles. The three together form a complete organic whole.

[0030] Reference Figure 2 The main body of the mounting mechanism 2 is mechanism block 1 204, and the main body of the rotating mechanism 3 is mechanism block 2 301. Mechanism block 1 204 is rotatably connected to the upper end of mechanism block 2 301, and valve island 1 is installed on the upper end of mechanism block 1 204. This layered structural layout clearly defines the three functional levels of fixing, mounting and rotating.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4The installation mechanism 2 achieves the installation of the valve island 1 through a double locking structure. The first locking structure is located on the upper left side of the mechanism block 204, including a position groove 205 and an L-shaped locking block 206 slidably connected inside the position groove 205. Corresponding to the L-shaped locking block 206, a locking groove 201 is provided on the lower left side of the valve island 1. The second locking structure is located on the upper right side of the mechanism block 204, including a position groove 208, an automatic rotator 209 fixed inside the position groove 208, and a locking plate 210 fixedly connected to the output end of the automatic rotator 209. Corresponding to 10, a guide groove 202 is provided on the lower right side of the valve island 1. The upper end of the guide groove 202 is connected to a rotating groove 203. A spring piece 207 is fixedly connected to the lower right side of the L-shaped locking block 206. The other end of the spring piece 207 can elastically deform and abut against the inner wall of the position groove 205 to provide key elastic potential energy during installation. An annular rubber groove 211 is also provided on the upper end of the position groove 208. A rubber ring 212 is fixed inside the rubber groove 211. After the valve island 1 is installed in place, the rubber ring 212 can abut against the lower surface of the valve island 1 to form a seal, effectively preventing external impurities from entering.

[0032] As a preferred embodiment, to provide flexibility in adjusting the installation direction of the valve island 1, please refer to... Figure 5 The modular valve island with an easy-to-install slide valve structure also includes a rotating mechanism 3. The rotating mechanism 3 realizes the rotation and positioning functions through a rotating shaft 305 and a circumferential positioning structure. The rotating shaft 305 is fixedly installed in the connecting groove 303 in the middle of the lower end of the mechanism block 1 204. The lower end of the rotating shaft 305 extends to the rotating groove 302 in the middle of the upper end of the mechanism block 2 301 and is rotatably connected to the rotating groove 302, realizing smooth rotation support. The circumferential positioning structure includes a position groove 304 formed around the outside of the connecting groove 303, a semi-circular locking block 307 slidably connected inside the position groove 304, and a spring piece 2 306 fixedly connected to the upper end of the semi-circular locking block 307. The other end of the spring piece 2 306 abuts against the inner wall of the top of the position groove 304. Correspondingly, a locking groove 2 308 is formed around the rotating groove 302 in the middle of the inner side of the mechanism block 2 301 for engaging with the semi-circular locking block 307.

[0033] As a further definition of the component shape, the L-shaped locking block 206 includes a horizontal part and a vertical part that are perpendicular to each other. The horizontal part is slidably received in the position groove 205, and the vertical part protrudes upward to be locked into the locking groove 201. At the same time, the width of the rotating groove 203 along the extension direction of the guide groove 202 is greater than the width of the guide groove 202 to ensure that the rotating locking plate 210 can form an effective overlap. The spring sheet 207 is preferably a sheet spring made of metal to ensure elasticity and durability.

[0034] Working principle:

[0035] During installation, the slot 201 of valve island 1 first engages with the L-shaped locking block 206 to achieve initial positioning. Then, valve island 1 is pulled to the right to compress the spring 207, while the locking plate 210 is guided along the guide groove 202. The automatic rotator 209 drives the locking plate 210 to rotate and engage with the rotating groove 203. After the tension is released, the rebound force of the spring 207 pushes valve island 1 to the left, so that the L-shaped locking block 206 and the locking plate 210 simultaneously lock valve island 1 firmly onto mechanism block 204 from two directions.

[0036] When adjusting the direction, rotate valve island 1, and mechanism block 204 will rotate around the rotating shaft 305. During the rotation, the semi-circular locking block 307 will slide out of one slot 308 and lock into the next slot 308 in turn under the action of spring piece 306, thereby achieving step-by-step angle positioning with a clear sense of gear position.
