Description

Technical Field

[0001] The utility model relates to the technical field of solar cell assembly laminating machine case cylinder opening and closing components, and more specifically to a solar cell laminating machine case anti-falling cylinder locking device. Background Art

[0002] At present, in the field of solar cell module laminating machines, the upper box body is hinged with the cylinder, and the upper box body is driven to rise and fall (open and close) by the extension and contraction of the cylinder. The opening and closing of the upper box body is generally a positive operation: when the cylinder is exhausted, the cover is opened, and when the upper box body reaches the corresponding height, the one-way valve can prevent air from entering the cylinder, ensuring that the upper box body is at a stable height; when the upper box body needs to descend, the inflation valve can be opened automatically or manually to allow the upper box body to descend slowly and evenly.

[0003] However, sometimes due to equipment space and other factors, it is necessary to use the cylinder with its back opened. The opening and closing of the upper box body and the charging and discharging of the cylinder are in opposite relationship, that is, the cover is opened for charging and closed for exhausting. At this time, due to special reasons such as sudden air or power outage, the cylinder may be quickly exhausted or leaked, causing the upper box body to suddenly fall, resulting in danger.

[0004] Therefore, providing a safe and reliable solar laminator cabinet anti-fall cylinder locking device is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In view of this, the utility model provides a solar laminator box anti-fall cylinder locking device, which can prevent the box from falling suddenly and is safe and reliable.

[0008] By adopting the above technical solution, the beneficial effects of the utility model are:

[0009] No matter there is a sudden power outage or gas failure, the cylinder can be locked to prevent air leakage, thereby ensuring that the box cannot fall suddenly and ensuring safety.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3 As shown, the embodiment of the utility model discloses a solar laminator box anti-fall cylinder locking device, including a three-way 1, an air intake check valve 2, a two-way valve 3, an exhaust throttle valve 4 and a connecting pipe 5, wherein the air intake check valve 2 is installed on the first interface of the three-way 1; the two-way valve 3 is installed on the second interface of the three-way 1, and the second interface and the first interface are located on the same horizontal line; the exhaust throttle valve 4 is installed on the outer interface of the two-way valve 3; the top end of the connecting pipe 5 is installed on the third interface of the three-way 1, and the bottom end of the connecting pipe 5 is installed on the gas inlet and outlet of the cylinder 7 through a joint 6. The utility model can ensure that the cylinder 7 can be locked regardless of sudden power failure or gas failure, so that it does not leak, thereby ensuring that the box 8 cannot fall suddenly, thereby ensuring safety.

[0020] Specifically, the gas inlet and outlet and the joint, the joint and the bottom end of the connecting pipe 5, the third interface and the top end of the connecting pipe 5, the first interface and the air intake check valve 2, and the second interface and the two-way valve 3 are all threadedly connected.

[0021] Specifically, the joint 6 is an internal and external thread nut.

[0022] Specifically, the gas inlet and outlet are provided with a first internal thread, and the joint 6 is provided with a first external thread matched with the first internal thread; the joint 6 is provided with a second internal thread, and the bottom end of the connecting pipe 5 is provided with a second external thread matched with the second internal thread; the third interface is provided with a third external thread, and the top end of the connecting pipe 5 is provided with a third internal thread matched with the third external thread; the first interface is provided with a fourth external thread, and the intake check valve 2 is provided with a fourth internal thread corresponding to the fourth external thread; the second interface is provided with a fifth external thread, and the two-way valve 3 is provided with a fifth internal thread corresponding to the fifth external thread.

[0023] Specifically, the exhaust throttle valve 4 is an exhaust throttle valve with a muffler.

[0024] The working principle of this utility model:

[0025] When inhaling, air is taken in from the inlet check valve 2, and when exhausting, air is exhausted from the exhaust throttle valve 4. It is open when inflating and closed when exhausting.

[0026] When special conditions occur during the opening:

[0027] 1. Sudden gas failure. When the gas source is suddenly disconnected and the gas cannot be supplied, that is, the intake check valve 2 cannot take in air, the exhaust throttle valve 4 can still work normally, so that the gas is discharged at a uniform speed without a sudden drop, and the airtightness of the cylinder 7 can be ensured, so that the opening can be maintained continuously.

[0028] 2. Sudden power failure. When the power is suddenly cut off, there is a risk of air leakage. The air intake check valve 2 can only allow air to enter but not to leave, so it can be guaranteed not to leak. On the exhaust throttle valve 4 side, since the two-way valve 3 is installed in front of it, when the power is suddenly cut off, the two-way valve 3 is in a closed state, which can immediately block the original exhaust gas path, making it impossible to enter or leave air.

[0029] In summary, no matter there is a sudden power outage or gas failure, the cylinder can be locked to prevent air leakage, thereby ensuring that the box body 8 cannot fall suddenly.

[0030] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
