Description

Technical Field

[0001] The utility model belongs to the technical field related to fresh air systems, and particularly relates to a PP floor air duct for preventing interface degumming. Background Technique

[0002] PP is the abbreviation of polypropylene, which is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and is resistant to a variety of organic solvents and acid-base corrosion. It has a wide range of applications in the industrial field and is one of the common polymer materials. It is mainly used for the production of various long and short polypropylene fibers, for the production of polypropylene woven bags, packing bags, injection molded products, etc. for the production of flame-retardant parts of electrical appliances, telecommunications, lighting, lighting equipment and televisions. In the fresh air system, when transporting cooled air, the floor air duct made of PP can be better used, but it still has the following disadvantages in actual use:

[0003] 1. During the connection process of the PP floor air duct and the corresponding adapter, by applying glue to the connection position of the PP floor air duct connecting device, the PP floor air duct and the adapter are bonded together to complete the installation. After the glue contacts the air for a long time, the glue between the PP floor air duct and the adapter will degum, causing the PP floor air duct and the adapter to separate, resulting in the leakage of the cooled air transported in the PP floor air duct between the PP floor air duct and the adapter;

[0004] 2. When the cooled air transported in the PP floor air duct encounters the adapter, the air is directly guided into the adapter. During use, when the air just enters the adapter, the impact of the air is completely received by the adapter. After long-term use, the adapter is easily damaged. Content of the Utility Model

[0005] The purpose of the utility model is to provide a PP floor air duct for preventing interface degumming. By setting a pipe body, an outer closed frame, a connecting strip and an empty shell, the problems that the PP floor air duct is prone to degumming when bonded with an air duct adapter and contacting air during operation, and the impact of the air transported to the adapter is large and easily causes damage to the adapter are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a PP ground air duct for preventing interface degumming, which comprises a duct body, an outer closed frame, a connecting strip and a hollow shell. One end of the inner side of the duct body is fixedly provided with the hollow shell, and one end of the outer side of the duct body close to the hollow shell is fixedly provided with the outer closed frame. The top of the outer closed frame is rotatably connected with the connecting strip, and one end of the bottom of the connecting strip far away from the outer closed frame is fixedly provided with an adhesive sheet. When working, the utility model conveys the cooled air through the duct body, closes the connection position between the duct body and the duct adapter through the outer closed frame, enables the duct body to be bonded with the duct adapter through the connecting strip during working, and guides the air conveyed therein through the hollow shell in the duct body.

[0008] Further, soft protection plates are fixedly arranged on the top and bottom of the duct body, annular reinforcing strips are fixedly arranged on the inner wall of the duct body at equal intervals, and guiding strips are fixedly arranged on both sides of the annular reinforcing strips. The guiding strips are fixedly arranged on the inner wall of the duct body. During the working process of the duct body, the soft protection plates reduce the pressure received by the guiding strips.

[0009] Further, a reinforcing rib is fixedly arranged at one end of the outer closed frame far away from the duct body, and a connecting rod is fixedly arranged at the center of the top of the outer closed frame. During the working process of the outer closed frame, the reinforcing rib is used to cooperate to increase the sealing property between the outer closed frame and the pipeline adapter.

[0010] Further, a limiting disc is fixedly arranged at the top end of the connecting rod, and the connecting column barrel is limited on the top of the outer closed frame.

[0011] Further, a connecting column is fixedly arranged at one end of the connecting strip close to the duct body, and a movable hole is formed through the center of one end face of the connecting column. The connecting rod is movably connected through the movable hole. During the working process of the connecting strip, the connecting rod is movably connected in the movable hole on the connecting column, so that the outer closed frame and the connecting strip are connected together.

[0012] Further, the inside of the hollow shell is of a hollow structure, and three vertical reinforcing plates are fixedly arranged vertically in the hollow shell. The distances between the vertical reinforcing plates are equal. The hollow shell increases its own strength through the vertical reinforcing plates.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the PP floor air duct is prone to glue detachment when it works and is adhesively bonded to the pipeline adapter and contacts air by setting a pipeline body, an outer closed frame and a connecting strip. The outer closed frame and the pipeline adapter are bound together by the reinforcing rib, increasing the sealing performance of the gap between the pipeline body and the pipeline adapter. After rotating the connecting strip to align with the pipeline adapter, the connecting strip is attached to the pipeline adapter through the adhesive film, completing the connection between the pipeline body and the pipeline adapter. At this time, when there is looseness between the pipeline body and the corresponding adapter, through the adhesion between the connecting strip and the adhesive film and with the cooperation of the outer closed frame, it is ensured that there is no looseness between the pipeline body and the adapter, so that during operation, both the connection strength between the PP floor air duct and the pipeline adapter can be increased, and the oxidation of the glue between the PP floor air duct and the pipeline adapter in contact with air can be reduced, preventing the glue detachment phenomenon between the PP floor air duct and the pipeline adapter.

[0015] 2. The utility model solves the problem that the adapter is easily damaged due to the large impact when the air is conveyed to the adapter during the operation of the PP floor air duct by setting a pipeline body and an empty shell. When the cooled air is conveyed in the pipeline body, when the cold air reaches the end where the pipeline body is connected to the adapter, the air in the pipeline body is guided into the pipeline adapter through the empty shell, and the impact generated by the air in the pipeline body directly impacts on the empty shell and can be guided into the pipeline adapter, which can better prevent the adapter from being damaged.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Please refer to Figures 1-5 As shown, the present utility model is a PP ground air duct for preventing interface degumming, including a duct body 100, an outer closed frame 200, a connecting strip 300 and a hollow shell 400. One end of the inner side of the duct body 100 is fixedly provided with a hollow shell 400. When the duct body 100 is working, it is used to transport the cooled air. The hollow shell 400 is supported by a flexible material, and guides the air led to it into the duct adapter. One end of the outer side of the duct body 100 close to the hollow shell 400 is fixedly provided with an outer closed frame 200. When the outer closed frame 200 is working, it cooperates to seal the gap at the connection position between the duct body 100 and the duct adapter. The top of the outer closed frame 200 is rotatably connected with a connecting strip 300. When the connecting strip 300 is attached to the duct adapter, when the connection between the duct adapter and the duct body 100 becomes loose due to stress, the connection stability between the duct adapter and the duct body 100 is increased. One end of the bottom of the connecting strip 300 away from the outer closed frame 200 is fixedly provided with an adhesive film 301, and the connecting strip 300 is adhered to the duct adapter through the adhesive film 301.

[0025] Among them, as Figure 1 、 2 shown, soft protection plates 101 are fixedly provided at the top and bottom of the duct body 100. When the duct body 100 is under pressure, the soft protection plates 101 protect the duct body 100 and reduce the pressure at the pressed position. Annular reinforcing strips 102 are fixedly provided equidistantly on the inner wall of the duct body 100. When the annular reinforcing strips 102 are working, they increase the strength of the duct body 100. Guide strips 103 are fixedly provided on both sides of the annular reinforcing strips 102. The guide strips 103 are fixed on the inner wall of the duct body 100. When the guide strips 103 are working, they reduce the resistance of the air transported in the duct body 100.

[0026] Among them, as Figure 1 、 3 shown, a reinforcing rib 201 is fixedly provided at one end of the outer closed frame 200 away from the duct body 100. When the reinforcing rib 201 is working, it increases the binding strength of the outer closed frame 200 at the duct adapter. A connecting rod 202 is fixedly provided at the center of the top of the outer closed frame 200. The outer closed frame 200 is connected to a connecting column 302 through the connecting rod 202.

[0027] Among them, as Figure 1 、 3 shown, a limiting disc 203 is fixedly provided at the top end of the connecting rod 202. When the limiting disc 203 is working, it limits the position of the connecting column 302 through the limiting disc 203.

[0028] Among them, asFigure 1 , 4 As shown, a connecting column 302 is fixed to one end of the connecting strip 300 close to the pipe body 100, and a movable hole 303 is opened in the center of one end face of the connecting column 302. The connecting rod 202 is movably connected in the movable hole 303. The connecting rod 202 and the connecting column 302 are movably connected, so that the connecting strip 300 is connected to the top of the outer closed frame 200.

[0029] Among them Figure 1 , 5 As shown, the interior of the empty shell 400 is a hollow structure, and three vertical reinforcement plates 401 are vertically fixed in the empty shell 400. The distances between the vertical reinforcement plates 401 are equal. When the empty shell 400 is working, the strength of the empty shell 400 is increased by the vertical reinforcement plates 401.

[0030] The specific working principle of the utility model is as follows: when working, the end of the pipe body 100 can be aligned with the end of the pipe adapter, and the pipe adapter is first inserted into the outer sealing frame 200, and then enters the pipe body 100 and is restricted in place by the empty shell 400, so that the pipe body 100 and the pipe adapter are connected together, and the outer sealing frame 200 and the pipeline adapter are bound together by the reinforcing ribs 201 to increase the sealing of the gap between the pipe body 100 and the pipe adapter, and then the connecting strip 300 is rotated to align with the pipe adapter, and the connecting strip 300 is attached to the pipe adapter through the adhesive sheet 301 to complete the connection between the pipe body 100 and the pipe adapter. At this time, when the pipe body 100 and the corresponding adapter are loose, through the adhesion between the connecting strip 300 and the adhesive sheet 301, With the cooperation of the outer sealing frame 200, it is ensured that the pipe body 100 and the adapter will not be loose. When burying the pipe body 100, the pipe body 100 connected with the adapter is placed in the groove opened on the ground. After the pipe body 100 is buried under the ground, when the top and bottom of the pipe body 100 are squeezed, the pressure of the pipe body 100 is reduced by the soft protective plate 101, and the compressive strength of the pipe body 100 is increased by the annular reinforcement strip 102. When the refrigerated air is transported in the pipe body 100, when the cold air is guided to the end where the pipe body 100 and the adapter are connected, the air in the pipe body 100 is guided into the pipe adapter through the empty shell 400, and the impact generated by the air in the pipe body 100 directly impacts the empty shell 400 and can be guided into the pipe adapter.

[0031] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
