Description

Technical Field

[0001] This invention relates to the field of air valve technology, and in particular to a top-mounted device for an air valve that can rotate eccentrically. Background Technology

[0002] The air valve is a component in a compressor used to control the entry and exit of gas into the cylinder.

[0003] Currently, air valves are generally rotated by a drive device during use.

[0004] However, the lack of a support device when the air valve rotates makes it prone to axial movement, affecting its normal use. Therefore, this invention is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a top-supporting device for an eccentrically rotatable air valve, which solves the problem in the prior art where the air valve lacks a top-supporting device when rotating, making it easy for the air valve to move axially during rotation and affecting its normal use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A valve-mounted, eccentrically rotatable support device includes a base, a valve body disposed inside the base, a support column slidably connected to the base, a support plate disposed at one end of the support column, four spherical bearings fixedly connected to one side of the support plate, and one side of each of the four spherical bearings being in contact with the valve body, a plurality of limit pin holes being opened at the top of the support column, a compression spring fixedly connected to the top of the base, a limit plate being elastically connected to the top of the compression spring, and a limit pin being fixedly connected to the bottom of the limit plate, one end of the limit pin penetrating the top of the base, and the extended end of the limit pin being located inside the limit pin hole, and the limit pin and the base being in clearance fit.

[0008] Preferably, the base has an L-shaped structure, with one end of the limiting pin passing through the top of the vertical section of the base via a sliding groove. A sliding hole is provided on the vertical section of the base, and the top post and the sliding hole are in clearance fit. The sliding hole and the sliding groove are interconnected. The four spherical bearings are all fixedly connected to the top plate by bolts. The top post is a rounded rectangle, the top plate is circular, and the four spherical bearings are arranged in a ring array.

[0009] Preferably, mounting plates are fixedly connected to both sides of one end of the top support column, threaded grooves are opened at both ends of one side of the top support plate, through holes are opened on the mounting plates, and fixing bolts are slidably connected in the through holes, and one end of the fixing bolts is connected to the inside of the threaded grooves by threaded engagement.

[0010] Preferably, a circular metal sheet is fixedly connected to the top of the limiting plate.

[0011] Preferably, a through groove is provided on the inner side of the top support column, and an adsorption hose is embedded in the inner side of the through groove. One end of the adsorption hose passes through the top support plate, and the extension end of the adsorption hose is connected to a suction cup. A fan is provided on one side of the base, and the air intake of the fan is connected to a suction hose. One end of the suction hose is connected to the adsorption hose. Through the cooperation between the adsorption hose, suction cup, fan and suction hose, the suction force of the fan is used to strengthen the backing of the top support plate and the spherical bearing against the valve body, but the valve body is not tightly sucked.

[0012] Preferably, a shut-off valve is installed on the adsorption hose.

[0013] Preferably, two support plates are fixedly connected to one side of the vertical section of the base. A compression spring is fixedly connected to one end of each support plate on the opposite side. A stabilizing plate is fixedly connected to one end of each compression spring on the opposite side. A clamping shaft is rotatably connected to the inner side of the stabilizing plate.

[0014] Preferably, the stabilizing plate has a U-shaped structure, and the two ends of the clamping shaft are rotatably connected to the inner sides of the stabilizing plate via rotating shafts.

[0015] This invention has at least the following beneficial effects:

[0016] Pulling the limit plate compresses the spring outward, causing the limit pin to slide and slide the top post. This moves the spherical bearing on the top post plate to align with the bottom of the valve body. After the top post plate is in position, release the limit plate. The spring releases its elastic potential energy, allowing the limit pin to be inserted into the limit pin hole, thus limiting the position of the top post plate. The spherical bearing then supports the valve body. Adjusting the front and rear support position of the valve body by sliding the top post plate is achieved. The spherical bearing and the bottom of the valve body plate experience sliding friction, preventing axial movement of the valve body during rotation. Even if the valve body and the top post plate's axis are offset by a certain distance, the valve body can still rotate normally.

[0017] The present invention also has the following beneficial effects:

[0018] 1. By coordinating the suction hose, suction cup, fan, and suction hose, the suction force of the fan strengthens the pressure of the top plate and spherical bearing against the valve body, but does not tightly suck the valve body, thus not affecting its rotation and preventing the valve body from shifting too far during rotation, which would affect normal operation.

[0019] 2. The shut-off valve can control the amount of gas output, thereby controlling the suction force on the valve body and the range of valve body displacement, which is quite practical.

[0020] The stability of the top support column is improved by the cooperation between the support plate, compression spring, stabilizing plate and clamping shaft, and the top support column is prevented from swinging in the sliding hole, so that the valve body can be better supported.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example 1

[0029] Reference Figure 1-5A top-support device for an eccentrically rotatable air valve includes a base 1, an air valve body 22 disposed inside the base 1, a top-support column 6 slidably connected to the base 1, a top-support plate 19 disposed at one end of the top-support column 6, four spherical bearings 20 fixedly connected to one side of the top-support plate 19, and one side of each of the four spherical bearings 20 being in contact with the air valve body 22, a plurality of limiting pin holes 7 being opened at the top of the top-support column 6, a compression spring 16 fixedly connected to the top of the base 1, a limiting plate 17 elastically connected to the top end of the compression spring 16, and a limiting pin 15 fixedly connected to the bottom of the limiting plate 17, one end of the limiting pin 15 penetrating through the top of the base 1, and the extended end of the limiting pin 15 located inside the limiting pin hole 7, and the limiting pin 15 and the base 1 being in clearance fit. The base 1 has an L-shaped structure. One end of the limiting pin 15 passes through the top of the vertical section of the base 1 via a sliding groove 14. A sliding hole 8 is provided on the vertical section of the base 1, and the top post 6 is clearance-fitted with the sliding hole 8. The sliding hole 8 and the sliding groove 14 are interconnected. Four spherical bearings 20 are fixedly connected to the top plate 19 by bolts. The top post 6 is a rounded rectangle, the top plate 19 is circular, and the four spherical bearings 20 are arranged in a ring array. A circular metal piece 18 is fixedly connected to the top of the limiting plate 17.

[0030] Specifically, pulling the limiting plate 17 causes the compression spring 16 to extend outward, allowing the limiting pin 15 to slide and slide the top post 6. This moves the spherical bearing 20 on the top plate 19 to fit against the bottom of the valve body 22. After the top post 6 is in position, the limiting plate 17 is released, the compression spring 16 releases its elastic potential energy, and the limiting pin 15 is inserted into the limiting pin hole 7 to limit the position of the top post 6. The spherical bearing 20 then supports the valve body 22. By sliding the position of the top post 6, the front and rear support positions of the valve body 22 can be adjusted, thus preventing axial movement when the valve body 22 rotates. The spherical bearing 20 and the bottom of the valve body 22 have sliding friction, so even if the valve body 22 is offset from the axis of the top plate 19 by a certain distance, it can still rotate normally. This also makes it convenient to support valves of different diameters. Example 2

[0031] Mounting plates 26 are fixedly connected to both sides of one end of the top support column 6. Threaded grooves 25 are opened at both ends of one side of the top support plate 19. Through holes 24 are opened on the mounting plate 26, and fixing bolts 23 are slidably connected in the through holes 24. One end of the fixing bolts 23 is connected to the inside of the threaded grooves 25 by threaded engagement.

[0032] Specifically, the installation plate 26, threaded groove 25, fixing bolt 23 and through hole 24 are provided to facilitate the replacement of the top plate 19 and the spherical bearing 20 together, thereby improving the convenience and durability of use. Example 3

[0033] A through groove 10 is provided on the inner side of the top support column 6. An adsorption hose 9 is embedded in the inner side of the through groove 10. One end of the adsorption hose 9 passes through the top support plate 19, and the extended end of the adsorption hose 9 is connected to a suction cup 21. A fan 13 is provided on one side of the base 1, and the air intake of the fan 13 is connected to a suction hose 12. One end of the suction hose 12 is connected to the adsorption hose 9. Through the cooperation between the adsorption hose 9, the suction cup 21, the fan 13, and the suction hose 12, the suction force of the fan 13 strengthens the pressure of the top support plate 19 and the spherical bearing 20 on the valve body 22, but does not tightly suck the valve body 22. A shut-off valve 11 is installed on the adsorption hose 9.

[0034] Specifically, through the cooperation between the suction hose 9, suction cup 21, fan 13, and suction hose 12, the suction force of the fan 13 strengthens the pressure of the top plate 19 and spherical bearing 20 on the valve body 22, but does not tightly suck the valve body 22, thus not affecting its rotation. This prevents the valve body 22 from deviating too far during rotation, which would affect normal operation. The shut-off valve 11 controls the amount of gas output, thereby controlling the suction force on the valve body 22, and consequently, the range of deviation of the valve body 22. This design is quite practical. Example 4

[0035] Two support plates 2 are fixedly connected to one side of the vertical section of the base 1. A compression spring 3 is fixedly connected to one end of each support plate 2 on the opposite side. A stabilizing plate 4 is fixedly connected to one end of each compression spring 3 on the opposite side. A clamping shaft 5 is rotatably connected to the inner side of the stabilizing plate 4. The stabilizing plate 4 has a U-shaped structure, and both ends of the clamping shaft 5 are rotatably connected to the inner sides of the stabilizing plate 4 via a rotating shaft.

[0036] Specifically, the stability of the top support column 6 is improved by the cooperation between the support plate 2, the compression spring 3, the stabilizing plate 4 and the clamping shaft 5, and the top support column 6 is prevented from swinging in the sliding hole 8, so that the valve body 22 can be better supported.
