Description

Technical Field

[0001] The utility model relates to the technical field of sealing strip compression, in particular to a PVC sealing strip compression device for a moisture-proof metal cabinet. Background Art

[0002] Metal cabinets are typically made of aluminum alloy or stainless steel. They are often used to store items, documents, or tools. To prevent moisture from entering these cabinets, PVC sealing strips are typically installed on the metal cabinet door frame using a clamping device. This ensures the cabinet maintains a good seal in humid environments, preventing moisture from entering and protecting the items inside.

[0003] After searching, the Chinese patent "A device for pressing sealing strips for aluminum alloy doors and windows" with authorization announcement number "CN221194879U" uses a pressing platform, guide channel, adjustment device, pressing wheel, rotating device and positioning wheel to pass the strip through the guide channel and press the strip into the frame, simplifying the pressing process and greatly improving work efficiency. At the same time, it maintains a constant pressing force to ensure the pressing effect.

[0004] Since the opening diameter of the guide channel is small and the sealing strip is soft and has a large friction force, it is too inconvenient for the sealing strip to pass through the guide channel, thereby reducing the compression efficiency of the compression device on the sealing strip.

[0005] Therefore, a PVC sealing strip pressing device for a moisture-proof metal cabinet is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a PVC sealing strip pressing device for a moisture-proof metal cabinet in order to solve the above-mentioned problem, thereby improving the problem that it is too inconvenient for the sealing strip to pass through the guide channel.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions, a PVC sealing strip pressing device for a moisture-proof metal cabinet, comprising: a pressing frame, the rear end of the pressing frame is rotatably connected to a roller; an installation mechanism, the installation mechanism is arranged on the surface of the pressing frame; wherein, the installation mechanism includes a cover block hinged to the top of the pressing frame, the cover block and the inner wall of the pressing frame are rotatably connected to a plurality of pulleys, the inner wall of the pressing frame is rollingly connected to a plurality of first balls, the front end of the pressing frame is threadedly connected to a screw, the rear end of the screw is rotatably connected to an air cylinder, the inner wall of the air cylinder is filled with gas, the inner wall of the air cylinder is slidably connected to a piston rack, and the inner side of the piston rack is rotatably connected to a pressing wheel. The cover block is used to open the top opening of the compression frame, so that the sealing strip can be quickly and conveniently placed inside the compression frame. Compared with the existing inconvenience of the sealing strip passing through the inside of the compression frame, this method opens the top opening of the compression frame to make it more convenient for the sealing strip to pass through the inside of the compression frame. The roller and the first ball are used to guide and limit the sealing strip on the inside of the compression frame and the cover block. The screw, the air cylinder and the piston rack are used to ensure that the compression wheel will not press excessively on the surface of the sealing strip, thereby avoiding damage to the sealing strip during compression.

[0008] Preferably, a positioning bracket is slidably connected to the inner wall of the cover block, the lower end of the surface of the positioning bracket being clamped to the inner wall of the compression frame, a first spring is fixedly connected to one end of the inner wall of the cover block, the other end of the first spring is fixedly connected to a clamping rod, the surface of the clamping rod being clamped to the inner wall of the positioning bracket. The first spring, clamping rod, and positioning bracket lock the cover block to the top of the compression frame, ensuring stable guidance of the sealing strip by the compression frame and the inner side of the cover block.

[0009] Preferably, the surface of the air cylinder is fixedly connected to a balloon.

[0010] Preferably, the surface of the air cylinder is fixedly connected with an identification frame, and the inner wall of the identification frame is fixedly connected with transparent glass. The balloon and the identification frame limit the movement of the screw, ensuring that the pressing wheel does not over-extrude the sealing strip.

[0011] Preferably, a second spring is fixedly connected to the opposite end of the piston frame and the gas cylinder.

[0012] Preferably, the top and bottom ends of the roller and the pressure wheel are both connected in a rolling manner with an annularly distributed second ball bearing, which ensures that the roller moves smoothly on the inside of the metal cabinet door frame and the pressure wheel moves smoothly on the inside of the sealing strip.

[0013] Preferably, an anti-slip block is fixedly connected to the lower end of the surface of the positioning frame, and the surface of the anti-slip block is slidably connected to the inner wall of the pressing frame and the cover block. The anti-slip block limits the moving height of the positioning frame and prevents the positioning frame from falling out of the cover block during upward movement.

[0014] Preferably, a guide rod is fixedly connected to the surface of the air cylinder, and the surface of the guide rod is slidably connected to the inner wall of the compression frame. The guide rod is used to limit the movement of the air cylinder and avoid deviation when the screw drives the air cylinder to move.

[0015] The beneficial effects of the utility model are:

[0016] 1. The cover block enables the top opening of the compression frame to be opened, thereby allowing the sealing strip to be quickly and conveniently placed inside the compression frame. Compared with the existing method in which the sealing strip passes through the inside of the compression frame, which is inconvenient, this method enables the sealing strip to pass through the inside of the compression frame more conveniently by opening the top opening of the compression frame. The roller and the first ball bearing are used to guide and limit the sealing strip inside the compression frame and the cover block. The screw, the air cylinder and the piston rack ensure that the compression wheel does not press excessively on the surface of the sealing strip, thereby avoiding damage to the sealing strip during compression.

[0017] 2. The cover block is locked on the top of the compression frame by means of the first spring, the clamping rod and the positioning frame, ensuring that the compression frame and the inner side of the cover block provide stable guidance to the sealing strip.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4 The device, shown in FIG. , is a PVC sealing strip compression device for moisture-proof metal cabinets. The device comprises a compression frame 1, with a roller 2 rotatably connected to the rear end of the compression frame 1; and a mounting mechanism 3 disposed on the surface of the compression frame 1. The mounting mechanism 3 includes a cover block 31 hingedly connected to the top of the compression frame 1. The cover block 31 and the inner wall of the compression frame 1 are both rotatably connected to a plurality of pulleys 32. A plurality of first ball bearings are rollingly connected to the inner wall of the compression frame 1. A screw 33 is threadedly connected to the front end of the compression frame 1. The rear end of the screw 33 is rotatably connected to an air cylinder 34. The inner wall of the air cylinder 34 is filled with gas. A piston rack 35 is slidably connected to the inner wall of the air cylinder 34. A compression roller 36 is rotatably connected to the inner side of the piston rack 35. The top and bottom ends of the roller 2 and the compression roller 36 are both rollingly connected to annularly distributed second ball bearings. One end of the surface of the piston rack 35 is a rubber member, which is in close contact with the inner wall of the air cylinder 34.

[0025] The PVC sealing strip needs to be installed on the metal cabinet door frame, and the cover block 31 is pulled to open the top opening of the pressing frame 1. At this time, the PVC sealing strip is quickly placed into the pressing frame 1 and a part of the PVC sealing strip is in contact with the pressing wheel 36. The cover block 31 is pushed to close the top opening of the pressing frame 1, and the pressing frame 1 is pushed to make the roller 2 contact the inside of the metal cabinet door frame. The screw 33 is rotated, and the screw 33 moves as the inner wall of the pressing frame 1 rotates and drives the air cylinder 34 to move. The movement of the air cylinder 34 drives the piston rack 35 and the pressing wheel 36 to move, so that the pressing wheel 36 pushes the PVC sealing strip into the inside of the metal cabinet door frame. At this time, the pressing frame 1 is pushed to press the PVC sealing strip against the inside of the metal cabinet door frame, so that the PVC sealing strip is installed all around the inside of the metal cabinet door frame, thereby sealing and moisture-proofing the metal cabinet.

[0026] like Figure 3 As shown, the inner wall of the cover block 31 is slidably connected to a positioning frame 38, the lower end of the surface of the positioning frame 38 is clamped to the inner wall of the clamping frame 1, one end of the inner wall of the cover block 31 is fixedly connected to a first spring 310, and the other end of the first spring 310 is fixedly connected to a clamping rod 39, and the surface of the clamping rod 39 is clamped to the inner wall of the positioning frame 38.

[0027] Push the positioning frame 38 down to a suitable position so that the positioning frame 38 is stuck in the pressing frame 1. The elastic force of the first spring 310 pushes the clamping rod 39 to move so that the clamping rod 39 is stuck in the positioning frame 38, so that the cover block 31 is firmly locked on the top of the pressing frame 1.

[0028] like Figure 4 As shown, the surface of the air cylinder 34 is fixedly connected to a balloon 37, the surface of the air cylinder 34 is fixedly connected to an identification frame 312, the inner wall of the identification frame 312 is fixedly connected to transparent glass, and the piston frame 35 and the opposite end of the air cylinder 34 are fixedly connected to a second spring 311.

[0029] like Figure 4 As shown, the lower end of the surface of the positioning frame 38 is fixedly connected to the anti-slip block 313 , and the surface of the anti-slip block 313 is slidably connected to the inner wall of the pressing frame 1 and the cover block 31 .

[0030] like Figure 3 As shown, a guide rod is fixedly connected to the surface of the air cylinder 34 , and a surface of the guide rod is slidably connected to the inner wall of the pressing frame 1 .

[0031] When the present invention is in use, the two clamping rods 39 are pulled away from the positioning frame 38, the positioning frame 38 is pulled upward, the positioning frame 38 is moved away from the pressing frame 1, and the cover block 31 is pulled to open the top opening of the pressing frame 1. At this time, the PVC sealing strip is quickly placed in the pressing frame 1 and a part of the PVC sealing strip is in contact with the pressing wheel 36, and the cover block 31 is pushed to close the top opening of the pressing frame 1. The positioning frame 38 is pushed down to a suitable position so that the positioning frame 38 is stuck in the pressing frame 1. The elastic force of the first spring 310 pushes the clamping rod 39 to move, so that the clamping rod 39 is stuck in the positioning frame 38, so that the cover block 31 is firmly locked to the top of the pressing frame 1, and the pressing frame 1 is pushed so that the roller 2 contacts the inner side of the metal cabinet door frame. The screw 33 is rotated, and the screw 33 moves during the rotation of the inner wall of the pressing frame 1 and drives the air cylinder 34 to move. The air cylinder 34 moves, driving the piston frame 35 and the pressure wheel 36 to move, so that the pressure wheel 36 pushes the PVC sealing strip into the inner side of the metal cabinet door frame, and the screw 33 drives the air cylinder 34 to continue to move, and the piston frame 35 pushes the gas in the air cylinder 34 to be transported to the balloon 37 and squeezes the second spring 311. The gas in the balloon 37 is sufficient and stretches. When the balloon 37 stretches and hits the identification frame 312, the screw 33 is stopped, so that the pressure wheel 36 does not press excessively on the PVC sealing strip. At this time, the pressure frame 1 is pulled to move the roller 2 on the inner side of the metal cabinet door frame. The moving pressure wheel 36 presses the PVC sealing strip on the inner side of the metal cabinet door frame, and the pulley 32 and the first ball make the PVC sealing strip move smoothly on the inside of the pressure frame 1, so that the PVC sealing strip is installed all around the inner side of the metal cabinet door frame, thereby sealing and moisture-proofing the metal cabinet.

[0032] It should be noted that the clamping frame 1, the clamping wheel 36, the first spring 310, the second spring 311 and the balloon 37 in the above description are all relatively mature devices in existing technology applications, and the specific models can be selected according to actual needs.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
