Description

Technical Field

[0001] This utility model relates to an actuator, and more specifically, to a pneumatic actuator that is easy to connect. Background Technology

[0002] A pneumatic actuator is an actuator that uses gas, usually compressed air, as a power source. It is commonly used to control fluid control equipment such as valves, gates, and ball valves. A pneumatic actuator typically consists of two parts: a pneumatic drive unit and an actuator mechanism. The pneumatic drive unit uses gas energy to push a piston or diaphragm to open and close the valve or actuator mechanism.

[0003] One end of the pneumatic actuator is connected to the valve to realize the automatic opening and closing of the valve. There are many types of valves. In order to facilitate the connection between the pneumatic actuator and the valve, a corresponding connecting plate is designed to realize the installation of the valve and the pneumatic actuator. However, the existing connecting plate is too cumbersome in the process of connecting the valve and the pneumatic actuator. It even requires multiple adjustments of the rotation angle of the fasteners to achieve the alignment of the two. The operation is time-consuming and laborious, reducing the installation efficiency. Utility Model Content

Specific embodiments

[0027] The following further details the present utility model in conjunction with the drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0028] Refer to Figures 1 to 5 As shown, to achieve the above object, the present utility model provides the following technical solution: a pneumatic actuator convenient for connection, comprising an actuator body 1 and a connecting disc 2. A connecting edge 3 is provided at the lower end of the actuator body 1, a mounting hole 31 is provided in the middle of the connecting edge 3, a drive rod 11 is provided in the actuator body 1, and a polygonal insertion slot 12 is provided on the drive rod 11;

[0029] The connecting disc 2 comprises a connecting seat 21, a transmission rod 22 and a connecting sleeve 23, and the transmission rod 22 is rotatably connected in the connecting seat 21;

[0030] The connecting seat 21 is arranged in a "丄" shaped structure, and the connecting seat 21 comprises a connecting plate 211 and a connecting column 212. The connecting plate 211 is detachably connected to the valve;

[0031] The connecting column 212 is concavely provided with a limiting slot 2121 along its circumference, and the connecting sleeve 23 is slidably connected in the limiting slot 2121;

[0032] A connecting slot 32 for inserting the connecting sleeve 23 is provided on the connecting edge 3, and a limiting member 4 is provided on the connecting edge 3 and inserted into the connecting slot 32.

[0033] The design of this utility model connects the connecting sleeve 23 to the connecting plate 2. When the transmission rod 22 is aligned with the insertion slot 12, the position of the connecting sleeve 23 is aligned with the position of the connecting slot 32, which facilitates subsequent insertion. When the connecting plate 2 is separated from the actuator body 1, the connecting sleeve 23 is connected to the connecting post 212, which facilitates the storage of the connecting plate 2.

[0034] Once the connecting sleeve 23 is inserted into place, it can cooperate with multiple sets of limiting parts 4 to achieve fixation, thereby improving the fixing effect of the connecting plate 2.

[0035] The present invention is further configured such that: a first magnetic layer 2122 is provided at the upper end of the limiting groove 2121, and a magnetic part 231 is provided on the upper part of the connecting sleeve 23.

[0036] The design of this structure allows the connecting sleeve 23 to be pushed up along the limiting groove 2121 when the connecting plate 2 is installed on the valve, until the magnetic part 231 is magnetically connected to the first magnetic layer 2122. At this time, the space of the connecting plate 211 is increased, which makes it easier to install the connecting plate 211 onto the bolts on the valve.

[0037] The present invention is further configured such that: a second magnetic layer 2123 is provided at the lower end of the limiting groove 2121, and the connecting sleeve 23 is made of magnetic material.

[0038] Similarly, when the connecting plate 2 is in a specific state, the connecting sleeve 23 needs to be kept stable. At this time, the connection between the limiting groove 2121 and the second magnetic layer 2123 or the first magnetic layer 2122 ensures that the connecting sleeve 23 is not easily displaced.

[0039] The present invention is further configured such that: the connecting plate 211 is provided with multiple sets of connecting holes in the circumference, and each connecting hole is connected with a mounting bolt.

[0040] The design of this structure involves selecting the corresponding connecting plate 2 according to the valve type, then aligning the mounting holes 31 on the connecting plate 2 with the holes on the valve, and connecting them with mounting bolts, or connecting them with the flange on the valve.

[0041] This invention is further configured such that multiple sets of limiting members 4 are arranged at equal intervals along the circumference of the connecting edge 3. This structural design improves the stability of the installation.

[0042] It should be noted here that the connecting sleeve 23 in the attached diagram is installed by insertion, but a threaded connection is not excluded.

[0043] The present invention is further configured such that: the limiting member 4 includes a connecting rod 41, a connecting head 42, a connecting handle 43 and a connecting spring 44, with the connecting head 42 and the connecting handle 43 respectively disposed at both ends of the connecting rod 41;

[0044] A spring groove 33 is provided inside the connecting edge 3, and a connecting spring 44 is provided inside the spring groove 33. A sliding part is provided on the connecting rod 41, and the sliding part is slidably connected to the spring groove 33 and abuts against the connecting spring 44.

[0045] The connecting sleeve 23 has a limiting groove 232 along its circumference for the connector 42 to be inserted.

[0046] The end of the connector 42 away from the connecting rod 41 is provided with a guide slope. This structure is designed so that when the connecting sleeve 23 is inserted into the connecting groove 32, the upper end of the connecting sleeve 23 abuts against the guide slope, causing the sliding part to push the connecting spring 44 to compress it. When the connecting sleeve 23 passes the connector 42, and the limiting groove 232 aligns with the connector 42, the connector 42, under the action of the connecting spring 44, is inserted into the limiting groove 232, thus achieving fixation.

[0047] When disassembly is required, pull the connecting handle 43 from the outside to separate the limiting groove 2121 from the connector 42, thereby achieving disassembly.

[0048] The present invention is further configured such that: the connecting handle 43 is rotatably connected to one end of the connecting rod 41, the connecting handle 43 is provided with a limit block, and the connecting edge 3 is provided with a guide groove for the limit block to be inserted.

[0049] The design of this structure allows the guide groove to separate from the limiting block by rotating the connecting handle 43 during the pulling process, thereby limiting the limiting member 4. When the connecting handle 43 rotates back to align the guide groove with the limiting block, the limiting member 4 can be inserted into the connecting groove 32.

[0050] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
