Description

Technical Field

[0001] This utility model relates to the field of proportional valve technology, specifically a split-type modular proportional valve. Background Technology

[0002] In the field of proportional valves, modular split-type proportional valves are widely used in hydraulic control systems due to their detachability. Split-type proportional valves typically use bolted connections or flange connections to fix the valve body to the control unit. This type of structure achieves modular assembly through the cooperation of proportional valve components, meeting the needs of equipment maintenance and functional expansion.

[0003] However, in practical applications, the disassembly and installation of existing split proportional valve snap-fit ​​components are quite cumbersome. Traditional connection structures require tools to tighten and loosen bolts, and bolt connections require precise alignment of holes, resulting in low efficiency in the installation and disassembly of the control unit. This is especially true in scenarios where frequent maintenance or module replacement is required, affecting the ease of use of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a split-type modular proportional valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a split modular proportional valve, including a valve body, an intermediate valve body fixedly connected to the upper end of the valve body, a connecting seat fixedly connected to the upper end of the intermediate valve body, a locking block fixedly connected to the outside of the connecting seat, a control part provided at the upper end of the connecting seat, and a locking component provided on the outside of the control part.

[0006] The snap-fit ​​assembly includes metal plates fixedly installed on both sides of the control unit. The lower end of the metal plates is provided with a snap-fit ​​groove. The snap-fit ​​assembly also includes grooves opened on both sides of the control unit. A round shaft is rotatably connected in the groove. An extrusion strip is fixedly connected in the middle of the round shaft. A transmission frame is fixedly connected to both ends of the round shaft. A transmission rod is fixedly connected to one end of the transmission frame.

[0007] Preferably, the side of the card block away from the connecting seat has a smooth transition, and the card block corresponds to the card slot.

[0008] Preferably, the metal sheet has one straight section and the other inclined section. The straight section of the metal sheet is parallel to and fits against the side of the control part, and the end of the inclined section extends outward from the control part to form a guide slope.

[0009] Preferably, the end of the extrusion bar away from the circular shaft has a smooth transition, and the extrusion bar corresponds to the metal sheet.

[0010] Preferably, the transmission rod and the transmission frame form a concave structure with the opening facing the control part, and the distance between the concave side of the concave structure and the control part is greater than the distance between the end of the metal sheet and the control part.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by the corresponding cooperation between the card block and the card slot, and the guide slope of the inclined section of the metal sheet, the installation can be completed by inserting it. Pulling the transmission rod can drive the round shaft to rotate through the transmission frame, so that the extrusion strip synchronously extrudes the metal sheet to produce elastic deformation, thereby separating the card slot from the card block. The operator can unlock it by lifting the transmission rod with one hand, realizing tool-free quick disassembly and assembly. The structure is simple and easy to use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution:

[0020] Example 1: A split modular proportional valve includes a valve body 1, an intermediate valve body 2 fixedly connected to the upper end of the valve body 1, a connecting seat 3 fixedly connected to the upper end of the intermediate valve body 2, a locking block 4 fixedly connected to the outer side of the connecting seat 3, a control part 5 provided at the upper end of the connecting seat 3, and a locking assembly provided on the outer side of the control part 5; the locking assembly includes metal plates 6 fixedly installed on both sides of the control part 5, a locking groove 7 opened at the lower end of the metal plates 6, and grooves 8 opened on both sides of the control part 5, a round shaft 9 rotatably connected in the grooves 8, an extrusion strip 10 fixedly connected in the middle of the round shaft 9, a transmission frame 11 fixedly connected at both ends of the round shaft 9, and a transmission rod 12 fixedly connected to one end of the transmission frame 11;

[0021] The side of the locking block 4 away from the connecting seat 3 is smoothly transitioned. The locking block 4 corresponds to the locking groove 7. The metal sheet 6 has one straight section and the other inclined section. The straight section of the metal sheet 6 is parallel and fits against the side of the control part 5, and the end of the inclined section extends outward to the control part 5 to form a guide slope. The end of the extrusion strip 10 away from the round shaft 9 is smoothly transitioned. The extrusion strip 10 corresponds to the metal sheet 6. The transmission rod 12 and the transmission frame 11 form a concave structure with the opening facing the control part 5, and the distance between the concave side of the concave structure and the control part 5 is greater than the distance between the end of the metal sheet 6 and the control part 5.

[0022] In use, first align the control unit 5 with the upper end of the connecting seat 3, so that the locking block 4 on the outside of the connecting seat 3 is aligned with the slot 7 at the lower end of the metal piece 6, and press the control unit 5 down. The control unit 5 then drives the metal piece 6 to move. The guide slope at the end of the inclined section of the metal piece 6 provides an inlet angle for the locking block 4. After the metal piece 6 is squeezed by the locking block 4, its inclined section undergoes elastic deformation towards the inside of the control unit 5, which drives the slot 7 to tightly engage with the locking block 4, thereby firmly locking the control unit 5 and the connecting seat 3.

[0023] During disassembly, the thumb and middle finger pull the transmission rod 12 upwards. The transmission rod 12 then drives the round shaft 9 to rotate through the transmission frame 11. The rotating round shaft 9 then drives the extrusion strip 10 to extrude the metal sheet 6. The metal sheet 6 recovers its deformation, and the slot 7 separates from the block 4. At this time, the control part 5 can be easily removed, completing the disassembly operation. This achieves quick installation and disassembly of the control part 5, improving the modular maintenance efficiency of the proportional valve. Furthermore, the transmission rod 12 and the transmission frame 11 form a concave structure with the opening facing the control part 5. The distance between the concave side of the concave structure and the control part 5 is greater than the distance between the end of the metal sheet 6 and the control part 5. This distance ensures that during the lifting process, the concave side of the transmission rod 12 will not interfere with the movement of the end of the metal sheet 6.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
