Description

Technical Field

[0001] The utility model relates to the technical field of circuit components, in particular to a moisture-proof wire groove used in alpine regions. Background Art

[0002] A wire groove, also known as a wire routing groove, wiring groove, or cable tray, is an electrical tool used to neatly organize and fix power cords, data cables, etc. on walls or ceilings. It is generally made of plastic or metal materials and can serve different functions. The wire groove can protect wire bodies such as electric wires. If an electric wire leaks electricity, sparks will fly everywhere. If there are flammable substances nearby, it is easy to cause a fire. If the electric wire is wrapped with a wire groove, it can play a good fire prevention role.

[0003] In the prior art, wire grooves are generally installed inside walls or fixed on the surfaces of walls and floors. Their interiors are used for arranging electric wires. When used in alpine regions, due to the influence of cold temperatures, the circuit loses the working temperature requirement. When it exceeds its working temperature range, the circuit may not work and its service life may be affected. Electric wires are generally made of polymer materials. When the region is relatively cold, the molecular movement of polymer materials slows down, the elasticity decreases, and they become hard and brittle, causing phenomena such as cracking and breaking of the electric wires, reducing the service life of the electric wires. Moreover, when the wire groove is installed in a damp location such as a basement, after the surface layer of the electric wire ruptures, the inner core of the electric wire is exposed to the damp air, which will cause an air discharge phenomenon, resulting in electric sparks, causing serious disasters such as fires and electric shocks, and causing casualties and property losses. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and propose a moisture-proof wire groove used in alpine regions.

[0005] To achieve the above object, the utility model adopts the following technical solutions: A moisture-proof wire groove for use in alpine regions, including a wire substrate. A plurality of air holes are provided on both sides of the inner wall of the wire substrate. A circulation air duct is provided inside the wire substrate. The inner walls of the air holes intersect with the inner wall of the circulation air duct. One end of the inner wall of the circulation air duct is fixed with a heating wire, and one end of the inner wall of the circulation air duct is fixed with a fan. The heating wire is fixed with a fan on one side, and there is an air hole on the other side of the heating wire. The other end of the inner wall of the circulation air duct is fixed with a turbine fan, and there is an air hole on one side of the turbine fan. In the prior art, the wire groove is generally installed in the wall or fixed on the surface of the wall and the ground, and the inside is used for arranging wires. When used in alpine regions, due to the influence of cold temperature, the circuit loses the working temperature requirement. When it exceeds its working temperature range, the circuit may not work and its service life may be affected. The wire is generally made of polymer material. When the region is relatively cold, the molecular movement of the polymer material slows down, the elasticity decreases, and it becomes hard and brittle, causing phenomena such as cracking and breaking of the wire, reducing the service life of the wire. And when the wire groove is installed in a damp place such as a basement, after the surface layer of the wire is broken, the inner core of the wire is exposed to the damp air, which will cause an air discharge phenomenon, resulting in electric sparks, causing serious disasters such as fires and electric shocks, causing casualties and property losses. To solve such problems, the utility model adopts the method of installing a circulation air duct. When the wire groove is installed in an alpine region and the environmental temperature is relatively low, the user starts the fan and the turbine fan to blow air to the heating wire. The hot air blows into the wire substrate from the air holes. After the turbine fan rotates to generate negative pressure and sucks the hot air into the circulation air duct, it passes through the fan and the heating wire again to form an internal circulation, quickly increasing the temperature inside the wire substrate, drying the damp air, avoiding the influence of dampness and low temperature on the wire, and achieving the effect of increasing the service life of the wire.

[0006] Preferably, fixing long grooves are formed on both sides of the inner wall of the wire substrate. An installation card is slidably connected to the fixing long groove. One end of the installation card is fixed with an upper folding wall, and one end of the installation card is fixed with a lower folding wall. One end of the upper folding wall is rotatably connected to one end of the lower folding wall. Side fixing grooves are formed on one side of the upper folding wall and the lower folding wall. A snap spring is arranged on the inner wall of the side fixing groove. One end of the snap spring is fixed to the upper folding wall, and the other end of the snap spring is fixed to the lower folding wall. In the prior art, when installing wires into the wire groove, the staff slowly puts the wires into one end of the wire groove, or ties the wires to a wire or a stick, inserts the wire or the stick into one end of the wire groove, and then takes out the wires from the other end of the wire groove to complete the laying. The steps are relatively cumbersome, and later maintenance is more troublesome. Once the wires have problems, the wire groove needs to be cut open to check, which reduces the user experience, damages the wire groove, and shortens the service life of the device. To solve such problems, the present utility model adopts the method of installing the upper folding wall and the lower folding wall. When the staff installs the wires, the wire substrate can be fixed and raised. After arranging the wires on the surface of the wire substrate, the staff presses the upper folding wall and the lower folding wall inward, so that the upper folding wall and the lower folding wall rotate and contract inward. The snap spring is compressed to accumulate elastic potential energy. The staff aligns the installation card with the fixing long groove and releases it. The snap spring releases the elastic potential energy, causing the upper folding wall and the lower folding wall to rotate and rebound outward, sliding the installation card into the fixing long groove, and fixing the upper folding wall and the lower folding wall to the wire substrate. When the wires have problems, the staff only needs to remove the upper folding wall and the lower folding wall again according to the above steps, perform maintenance and then install them again, without damaging the main structure, achieving the effects of improving the user experience and increasing the product service life.

[0007] Preferably, wing parts are fixed to both the top and the bottom of the wire substrate. A plurality of fixing holes are formed on the surface of the wing parts. A fixing nail is slidably connected to the inner wall of the fixing hole. A gripping part is slidably connected to the surface of the fixing nail. A high-strength column is fixed to the bottom of the gripping part. A fixing seat is fixed to the bottom of the high-strength column. A hexagonal press is threadedly connected to the surface of the high-strength column. In the prior art, the wire groove is fixed with nails. If a user temporarily rents an office building and uses a metal wire groove, and then changes the office after a period of time, and the purchase cost of the metal wire groove is relatively high, if the user wants to take it away, he needs to pull out the nails one by one, which is time-consuming and laborious and reduces the user experience. To solve such problems, the present utility model adopts the method of installing wing parts. When the user needs to fix the wire groove, the fixing nail can be directly fixed to the wall or the ground through the fixing hole. When the user only uses the wire groove temporarily, the fixing seat can be fixed to the wall or the ground in advance, and then the fixing nail is slid into the gripping part and screwed into the hexagonal press to compress the gripping part, so that it tightly grips the fixing nail, and it can avoid the fixing nail from wearing the surface of the wire groove, achieving the effect of facilitating the disassembly and assembly by the staff.

[0008] Preferably, friction-increasing hand grooves are formed on one side of the upper folding wall and the lower folding wall, which is convenient for the staff to use.

[0009] Preferably, a plurality of wire grooves are formed on one side of the wire substrate, facilitating the staff to arrange wires.

[0010] Preferably, a plurality of insulating walls are fixed on one side of the wire substrate to prevent the exposure of the core of a certain wire from affecting other circuits.

[0011] Preferably, an upper bite tooth is fixed at the top end of the other side of the wire substrate, and a lower bite tooth is fixed at the bottom end of the other side of the wire substrate, improving the biting effect of the wire substrate on the wall and increasing the contact area between the back glue and the wire substrate.

[0012] Beneficial effects

[0013] 1. In the prior art, wire grooves are generally installed inside the wall or fixed on the surface of the wall and the ground, and wires are arranged inside them. When used in alpine regions, due to the influence of cold temperatures, the circuit loses the working temperature requirement. When it exceeds its working temperature range, the circuit may not work and its service life may be affected. Wires are generally made of polymer materials. When the region is relatively cold, the molecular movement of polymer materials slows down, the elasticity decreases, and they become hard and brittle, causing phenomena such as cracking and breaking of the wires, reducing the service life of the wires. Moreover, when the wire groove is installed in a humid location such as a basement, after the surface of the wire breaks, the inner core of the wire is exposed to the humid air, resulting in an air discharge phenomenon, causing electric sparks, and leading to serious disasters such as fires and electric shocks, causing casualties and property losses. To solve such problems, the present utility model adopts the method of installing a circulating air duct. When the wire groove is installed in an alpine region and the environmental temperature is low, the user starts the fan and the turbine fan to blow air towards the heating wire. The hot air blows into the wire substrate from the air holes. The turbine fan rotates to generate negative pressure and sucks the hot air into the circulating air duct, and then passes through the fan and the heating wire again to form an internal circulation, quickly increasing the temperature inside the wire substrate, drying the humid air, avoiding the influence of humidity and low temperature on the wires, and achieving the effect of increasing the service life of the wires.

[0014] 2. In the prior art, when installing wires into a wire duct, workers slowly insert the wires from one end of the wire duct, or tie the wires to a wire or a stick, insert the wire or the stick into one end of the wire duct, and then take out the wires from the other end of the wire duct to complete the laying. The steps are relatively cumbersome, and subsequent maintenance is also rather troublesome. Once there is a problem with the wires, the wire duct needs to be cut open to check, which reduces the user experience, damages the wire duct, and shortens the service life of the equipment. To solve such problems, the present utility model adopts the method of installing an upper folding wall and a lower folding wall. When workers install wires, they can raise and fix the wire substrate. After arranging the wires on the surface of the wire substrate, the workers press the upper folding wall and the lower folding wall inward, causing the upper folding wall and the lower folding wall to rotate and contract inward. The clamping spring is compressed to accumulate elastic potential energy. The workers release the installation clip and align it with the fixed long groove. The clamping spring releases the elastic potential energy, causing the upper folding wall and the lower folding wall to rotate and rebound outward, sliding the installation clip into the fixed long groove, and fixing the upper folding wall and the lower folding wall to the wire substrate. When there is a problem with the wires, the workers only need to remove the upper folding wall and the lower folding wall again according to the above steps, perform maintenance and then install them again, without damaging the main structure, achieving the effects of improving the user experience and increasing the product service life.

[0015] 3. In the prior art, the wire duct is fixed with nails. If a user temporarily rents an office building and uses a metal wire duct, and then changes offices after a period of time, and since the purchase cost of the metal wire duct is relatively high and the user wants to take it away, they need to pull out the nails one by one, which is time-consuming and laborious and reduces the user experience. To solve such problems, the present utility model adopts the method of installing wing parts. When the user needs to fix the wire duct, they can directly fix the fixing nails to the wall or the ground through the fixing holes. When the user only uses the wire duct temporarily, they can fix the fixing base to the wall or the ground in advance, then slide the fixing nail into the grasping part, and screw the hexagonal press to compress the grasping part to tightly hold the fixing nail, and it can avoid the fixing nail from wearing the surface of the wire duct, achieving the effect of facilitating the disassembly and assembly by the workers.

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0026] The specific embodiments of the present utility model will be described below with reference to the drawings. Specific embodiment:

[0028] Refer to Figure 1-7, a moisture-proof wire groove used in alpine regions, includes a wire substrate 1. A plurality of air holes 104 are opened on both sides of the inner wall of the wire substrate 1. A circulation air duct 107 is opened inside the wire substrate 1. The inner walls of the air holes 104 intersect with the inner wall of the circulation air duct 107. One end of the inner wall of the circulation air duct 107 is fixed with a heating wire 105, and one end of the inner wall of the circulation air duct 107 is fixed with a fan 106. The heating wire 105 is fixed with a fan 106 on one side, and there is an air hole 104 on the other side of the heating wire 105. The other end of the inner wall of the circulation air duct 107 is fixed with a turbine fan 108, and there is an air hole 104 on one side of the turbine fan 108. The wire groove is generally installed inside the wall or fixed on the surface of the wall and the ground, and its interior is used for arranging electric wires. When used in alpine regions, due to the influence of cold temperature, the circuit loses the working temperature requirement. When it exceeds its working temperature range, it may cause the circuit to fail to work and affect its service life. Electric wires are generally made of polymer materials. When the area is relatively cold, the molecular movement of polymer materials slows down, the elasticity decreases, and they become hard and brittle, causing phenomena such as cracking and breaking of the electric wires, reducing the service life of the electric wires. And when the wire groove is installed in a humid place such as a basement, after the surface layer of the electric wire is broken, the inner core of the electric wire is exposed to the humid air, which will cause an air discharge phenomenon, causing electric sparks, resulting in serious disasters such as fires and electric shocks, causing casualties and property losses. It is solved by adopting the method of installing the circulation air duct 107. When the wire groove is installed in alpine regions and the environmental temperature is low, the user starts the fan 106 and the turbine fan 108 to blow air to the heating wire 105. The hot air blows into the wire substrate 1 from the air hole 104. After the turbine fan 108 rotates to generate negative pressure and sucks the hot air into the circulation air duct 107, it passes through the fan 106 and the heating wire 105 again to form an internal circulation, quickly increasing the temperature inside the wire substrate 1, drying the humid air, avoiding the influence of humidity and low temperature on the electric wires, and achieving the effect of increasing the service life of the electric wires. A plurality of wire grooves 102 are opened on one side of the wire substrate 1, which is convenient for the staff to arrange wires. A plurality of insulating walls 103 are fixed on one side of the wire substrate 1 to prevent the exposure of the core of a certain electric wire from affecting other circuits. An upper bite tooth 302 is fixed at the top end of the other side of the wire substrate 1, and a lower bite tooth 303 is fixed at the bottom end of the other side of the wire substrate 1, improving the biting effect of the wire substrate 1 on the wall and increasing the contact area between the back glue and the wire substrate 1.

[0029] On both sides of the inner wall of the wire substrate 1, there are fixed long grooves 101. The fixed long grooves 101 are slidably connected with mounting clips 205. One end of the mounting clip 205 is fixed with an upper folding wall 2, and one end of the mounting clip 205 is fixed with a lower folding wall 201. One end of the upper folding wall 2 is rotatably connected to one end of the lower folding wall 201. On one side of the upper folding wall 2 and the lower folding wall 201, there are side fixing grooves 203. Inside the side fixing grooves 203, there are retaining springs 204. One end of the retaining spring 204 is fixed to the upper folding wall 2, and the other end of the retaining spring 204 is fixed to the lower folding wall 201. When staff install wires into the wire groove, they slowly put the wire into one end of the wire groove, or tie the wire to a wire or a stick, insert the wire or the stick into one end of the wire groove, and then take out the wire from the other end of the wire groove to complete the laying. The steps are relatively cumbersome, and later maintenance is also more troublesome. Once the wire has a problem, the wire groove needs to be cut open to check, which reduces the user experience, damages the wire groove, and shortens the service life of the device. This problem is solved by adopting the method of installing the upper folding wall 2 and the lower folding wall 201. When staff install wires, the wire substrate 1 can be fixed. After arranging the wires on the surface of the wire substrate 1, the staff press the upper folding wall 2 and the lower folding wall 201 inward, so that the upper folding wall 2 and the lower folding wall 201 rotate and contract inward, and the retaining spring 204 accumulates elastic potential energy under pressure. The staff align the mounting clip 205 with the fixed long groove 101 and release it. The retaining spring 204 releases the elastic potential energy, causing the upper folding wall 2 and the lower folding wall 201 to rotate and rebound outward, sliding the mounting clip 205 into the fixed long groove 101, so that the upper folding wall 2 and the lower folding wall 201 are fixed to the wire substrate 1. When the wire has a problem, the staff only need to remove the upper folding wall 2 and the lower folding wall 201 again according to the above steps, perform maintenance and then install them again, without damaging the main structure, achieving the effect of improving the user experience and increasing the product service life. On one side of the upper folding wall 2 and the lower folding wall 201, there are anti-slip hand grooves 202, which are convenient for staff to use. On the top and bottom of the wire substrate 1, there are wing parts 3 fixed. On the surface of the wing parts 3, there are a plurality of fixing holes 301. Inside the fixing holes 301, there is a fixing nail 304 slidably connected. On the surface of the fixing nail 304, there is a gripping part 305 slidably connected. At the bottom of the gripping part 305, there is a high-strength column 306 fixed. At the bottom of the high-strength column 306, there is a fixing seat 307 fixed. On the surface of the high-strength column 306, there is a hexagonal press 308 threadedly connected. If the wire groove is fixed with nails, when a user temporarily rents an office building and uses a metal wire groove, and then changes the office after a period of time, and the purchase cost of the metal wire groove is relatively high, and the user wants to take it away, then the nails need to be pulled out one by one, which is time-consuming and laborious and reduces the user experience. This problem is solved by adopting the method of installing the wing parts 3. When the user needs to fix the wire groove, the fixing nail 304 can be directly fixed to the wall or the ground through the fixing hole 301. When the user only uses the wire groove temporarily, the fixing seat 307 can be fixed to the wall or the ground in advance, and then the fixing nail 304 is slid into the gripping part 305 and screwed into the hexagonal press 308 to press the gripping part 305 tightly, so that it tightly grips the fixing nail 304, and it can avoid the fixing nail 304 from wearing the surface of the wire groove, achieving the effect of facilitating the disassembly and assembly by the staff.

[0030] Working principle of the utility model: When the user needs to fix the wire duct, the fixing nail 304 can be directly fixed to the wall or the ground through the fixing hole 301. When the user only uses the wire duct temporarily, the fixing base 307 can be fixed to the wall or the ground in advance, and then the fixing nail 304 is slid into the grasping member 305, and screwed into the hexagonal press 308 to press the grasping member 305 tightly, so that it tightly grasps the fixing nail 304, and the surface of the wire duct can be prevented from being worn by the fixing nail 304. The wire duct 102 is convenient for the staff to arrange wires. The insulating wall 103 can prevent other lines from being affected when the core of a certain wire is exposed. When the staff installs the wire, the wire substrate 1 can be fixed. After arranging the wires on the surface of the wire substrate 1, the staff presses the upper folding wall 2 and the lower folding wall 201 inward, so that the upper folding wall 2 and the lower folding wall 201 rotate and contract inward, and the retaining spring 204 is compressed to accumulate elastic potential energy. The staff aligns the installation clip 205 with the fixing long slot 101 and releases it. The retaining spring 204 releases the elastic potential energy, so that the upper folding wall 2 and the lower folding wall 201 rotate and rebound outward, and the installation clip 205 is slid into the fixing long slot 101, so that the upper folding wall 2 and the lower folding wall 201 are fixed to the wire substrate 1. When the wire has problems, the staff only needs to remove the upper folding wall 2 and the lower folding wall 201 again according to the above steps, and reinstall them after maintenance, without damaging the main structure. When the wire duct is installed in a high-cold area, when the environmental temperature is low, the user starts the fan 106 and the turbine fan 108 to blow air to the heating wire 105. The hot air blows into the wire substrate 1 from the air hole 104. After the turbine fan 108 rotates to generate negative pressure and sucks the hot air into the circulation air duct 107, it passes through the fan 106 and the heating wire 105 again to form an internal circulation, quickly increasing the temperature inside the wire substrate 1, drying the humid air, and avoiding the influence of humidity and low temperature on the wires.

Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "beneath" and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.
