Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic conversion devices, in particular to a pneumatic two-position five-way reversing device. Background Art

[0002] Existing pneumatic reversing devices commonly used are electromagnetic pneumatic valves or manual reversing valves. For electromagnetic pneumatic valves (for example, three-position five-way electromagnetic reversing valves), in addition to being connected to the air pipe, they still need to be connected to the wiring. The entanglement of wires and pipes is not conducive to maintenance. Conventional manual reversing valves rely solely on mechanical parts for reversing transmission and have no relevant clamping measures. Opening and closing is just a matter of using an adjustable wrench. During use, the switch often fails to be turned into place. After long-term use, the internal reversing component may also fail to abut in place due to wear. There is also a reversing device that, in addition to the reversing component, also has an external handle switch. The connection between the two is redundant and the cost is high.

[0003] Therefore, there is an urgent need for a pneumatic two-position five-way reversing device that connects the handle and the reversing assembly into one body and can solve the above problems. Utility Model Content

[0036] like Figure 5 The inner core 2 includes a middle plug 202 that is tightly attached to the front, rear and lower end surfaces of the inner cavity 101. A left plug 201 and a right plug 203 are respectively provided on both sides of the middle plug 202, and a sealing plate 206 is fixed on the top of the three. The function is to be used for primary sealing of the top and to connect a contact 207 that can be manually pried open. A contact 207 passing through a toggle slot 2071 is installed on the sealing plate 206.

[0037] A sealing gasket 3 is installed between the cover 4 and the cavity 1 for side sealing. A groove with a diameter larger than the inner cavity 101 is provided on the inner side of the cover 4 to avoid increasing gaps and reduce air leakage, and a magnetic block b402 that fits therewith is installed in the groove. The outer edges of the sealing gasket 3 and the cover 4 are flush with the cavity 1, without protruding edges and corners, which is convenient for fixing the device on related equipment, and are all fixed by countersunk holes 401.

[0038] The side end surfaces of the left plug 201 and the right plug 203 are both provided with grooves, and magnetic blocks a205 attracted to the magnetic block b402 are installed in the grooves. When the contact 207 is moved left and right to both sides, it is labor-saving and the magnetic attraction is stable.

[0039] The lower edge of the sealing plate 206 is positioned higher than all the air holes to avoid blocking the airflow during reversal;

[0040] like Figure 6 As shown, when the left plug 201 is in close contact with the left sealing gasket 3, the working hole a103 and the working hole b104 are connected in the inner cavity 101, the air supply hole 102 is connected with the working hole d106, the working hole c105 is blocked by the right plug 203, and the two chambers formed by the working hole a103 and the working hole b104 and the air supply hole 102 and the working hole d106 are separated by the middle plug 202; when the left plug 201 is in close contact with the left sealing gasket 3, the left end face of the contact 207 abuts against the left inner wall of the toggle slot 2071,

The contact 207 extends through the toggle slot 2071 and out of the cavity 1. The front and rear ends of the contact 207 are respectively in contact with the front and rear inner walls of the toggle slot 2071 to limit the front and rear positions.

[0043] The upper end surface of the cavity 1 is provided with a top cover plate 208 that can completely cover the top of the toggle slot 2071, thereby providing a secondary seal on the top of the inner cavity 101 and further reducing the probability of air leakage. The center of the top cover plate 208 is connected to the contact 207. Both sides of the top cover plate 208 are provided with color mark holes 2081 that penetrate through the upper end surface of the cavity 1.

[0045] When the right end surface of the contact 207 abuts against the right inner wall of the toggle slot 2071 , the right color mark block 501 is completely covered by the top cover 208 , and the left color mark block 501 is visible through the left color mark hole 2081 .

[0046] The four working holes and air delivery holes in the present invention all use threaded air holes of uniform size, which makes it convenient for operators to plug in air pipes of the same specification; the airflow control direction of the present invention can be customized according to the connected air pipes, but it should be noted that: the working hole a103 and the working hole b104 are a group, and the working hole c105 and the working hole d106 are a group; this is all existing technology and will not be repeated.
