Technical field

The present application relates to a cleaning technology for a photovoltaic panel, and more particularly to a track mechanism of a photovoltaic panel cleaning device, a trolley running mechanism, and a cleaning device.

Background technique

Automated cleaning of planes or platforms that are erected outdoors is one of the problems that plague people. Among them, the automatic cleaning of the surface of the solar panel in the photovoltaic power station is particularly demanding for the cleaning equipment because of the harsh environment. For example, photovoltaic power plants located in the northwestern part of China are affected by the desertification environment. On average, the surface of the solar panels needs to be cleaned and cleaned every hour. The photovoltaic power station located near Hokkaido, Japan, needs more rain because of the snowy days. The snow environment performs fast and efficient cleaning. Obviously, in such a working environment, not only the performance of the cleaning equipment, the cleaning rate are required, but also the long service life under the working conditions (taking into account that the life of the supporting facilities is generally equivalent to the life of the solar panel. Therefore, it is generally required to be 10 years or more, high stability and low maintenance costs.

At present, the cleaning work of photovoltaic power plants is usually carried out by using a robot cleaning system. However, when using the robotic cleaning system, it is necessary to manually transport the robot and its supporting equipment to the solar panel before each cleaning, and the labor is not completely liberated. Moreover, the cost of the robot is high, the cleaning speed is slow, and maintenance is very difficult.

People have also considered installing a cleaning car on the solar panel and using the cleaning car to automate the cleaning of the solar panel.

Typically, the sweeping cart is pulled through the towline and advanced along the established rail. This combination of sweeping trolleys, traction ropes and rails is often referred to as the trolley operating mechanism. In the traditional trolley running mechanism, the traction rope is usually exposed, and in order to ensure the strength and cost of the traction rope, the steel rope is usually used as the traction rope, and the traction rope in parallel with the guide rail cannot be used due to the movement of the trolley. Protection is protected. This causes the traction rope that remains in the air for a long time to rust, thereby reducing the strength of the rope.

In addition, since the conventional trolley running mechanism is usually in a dust and snow environment, the guide rails are prone to dust accumulation, resulting in a generally short life of the guide rail and difficulty in maintenance.

Summary of the invention

The purpose of some embodiments of the present invention is to provide a trolley running mechanism. The trolley running mechanism can effectively prevent the rope of the traction trolley from being rusted, improve the dustproof and waterproof capability of the cleaning device, and further prolong the service life.

In order to solve the above technical problem, an embodiment of the present invention provides a trolley running mechanism, including a traction rope, a guide rail and a trolley. The trolley moves along the guide rail under the driving of the traction rope; wherein the inside of the guide rail forms a hollow tubular cavity. The body, at least a portion of the traction rope is located within the tubular cavity. Wherein, the rail has a strip-shaped hole, and the strip-shaped hole is connected to the outside of the tubular cavity and the guide rail; the trolley is provided with a connecting arm, and the connecting arm penetrates into the tubular cavity through the strip-shaped hole and is connected with the traction rope.

An embodiment of the present invention also provides a cleaning device comprising the above-described trolley running mechanism. Also, in one example, at least one traction mechanism and protective sleeve are included in the cleaning device. The traction rope extends from both ends of the guide rail and is connected to the traction mechanism. The protective sleeve is disposed between the traction mechanism and the guide rail, and the protective sleeve encloses the traction rope at least partially located between the traction mechanism and the guide rail. The protective sleeve can effectively prevent the traction rope from being exposed to the air and being rusted by the influence of wind, sand and rain.

In contrast to the prior art, one embodiment of the present invention solves the problem of rusting of the traction rope in parallel with the rail by burying at least a portion of the leash in the rail. And by using the protective sleeve disposed between the traction mechanism and the guide rail, the problem of corrosion of the traction rope protruding from the portion other than the guide rail is effectively prevented. According to the technical solution provided by the embodiment of the present invention, since the rust prevention requirement for the traction rope is omitted, the cost of the traction rope can be greatly reduced.

In one example, the strip-shaped holes extend through the guide rails in the longitudinal direction of the guide rails, and together with the tubular cavities, form a chute, and the connecting arms are moved along the chutes under the driving of the traction ropes. In this way, the trolley can be traversed into the guide rail from the outside of the guide rail through the chute, so that the maintenance required to disassemble the trolley becomes easier.

In one example, the edges of the strip holes are provided with a dust-proof top. Through the dust-proof tops, dust can be effectively prevented from entering the tubular cavity of the guide rail through the strip-shaped holes, thereby preventing the guide rail from being invalid due to dust accumulation. In addition, the dust-proof top strip also provides a damping effect on the connecting arm, which can prevent the trolley from continuously moving due to inertia, causing the traction rope to be wound around the rope.

In one example, the connecting arm can also penetrate the tubular cavity along the central axis of the rail in the vertical direction. The connecting arm that penetrates the tubular cavity through the central axis is more symmetrical due to the force position, and has better stability. At this point, the connecting arm can extend from the top of the rail into the tubular cavity or from the bottom into the tubular cavity. Since the bottom opening has better dustproof and rainproof effect with respect to the top opening, and in order to make the force uniform, the connecting arm can include two arms, and the two arms respectively bypass the left and right sides of the rail Side and merge at the bottom of the guide rail, and the connecting arm penetrates into the tubular cavity from the bottom of the guide rail body.

In one example, the top of the rail may also form a dust mites, the strip holes being located below the dust mites. At this time, the connecting arm can bypass the dust mitigation and protrude from the lower strip hole into the tubular cavity to be connected with the traction rope. The use of dust mites not only prevents dust from entering the tubular cavity, but also effectively blocks the intrusion of rain and snow, thereby extending the life of the equipment. Further, in one example, the strip-shaped holes may be located at the shoulder of the guide rail, and the connecting arm extends from the side of the guide rail into the tubular cavity; or the strip-shaped hole may also be located at the waist of the guide rail, and the connecting arm is guided from the guide rail The sides are inclined upwardly into the tubular cavity. When the strip hole is located at the shoulder of the rail, the height of the rail can be compressed to a greater extent, and when the strip hole is located at the waist of the rail, it has a better dustproof and waterproof effect.

In one example, the bottom of the rail is provided with a dovetail slot. The dovetail slot facilitates the assembly and fixing of the rails.

In one example, the cart is provided with rollers on the sides of the corresponding rails, and the rotating shaft of the rollers is perpendicular to the table on which the rails are mounted. Further, the center of the roller may be recessed inward to form a recessed portion; the two sides of the guide rail protrude outwardly to form a protruding portion; the protruding portions on both sides of the guide rail respectively cooperate with the corresponding recessed portions of the roller, so that the roller catches the guide rail . In contrast to the technical solution in which the roller is protruded and the guide rail is recessed, the protruding guide rail can effectively prevent dust from collecting, thereby preventing the rail resistance from increasing and failing.

In one example, when the strip hole is located at a shoulder of the rail, the shoulder of the rail has a portion extending toward the interior of the tubular cavity to form a brim covering the leash; when the strip hole When located at the waist of the rail, the waist portion of the rail extends partially into the interior of the tubular cavity to form a brim that covers the leash. The leash can be shielded by the brim in the tubular cavity to prevent the leash from being detached from the guide rail during the transfer process to ensure stable movement of the trolley on the guide rail.

In one example, the rail has N hollows; wherein the N is a natural number and the hollow is coincident with the length of the tubular cavity. By opening a plurality of hollow portions in the guide rail, the reliability of the guide rail can be reduced, and the guide rail can be more easily installed.

In addition, an embodiment of the present invention further provides a track mechanism of a photovoltaic panel cleaning device, comprising upper and lower rails respectively disposed on upper and lower sides of the photovoltaic panel unit; wherein the photovoltaic panel unit is covered with a frame body, and the upper and lower sides of the frame body are bent inwardly to form a hem surrounding the photovoltaic panel unit: the track mechanism of the photovoltaic panel cleaning device further comprises an upper bracket and a fixed fixed upper rail a lower bracket of the lower rail, and the upper and lower brackets respectively have clamping portions for clamping the photovoltaic panel unit frame; wherein the upper and lower clamping portions are respectively provided with hooking the frame The body of the hook claws.

Compared with the prior art, in the cleaning device, the upper bracket for fixing the upper rail and the lower bracket for fixing the lower rail respectively have upper and lower clamping portions, and hooks are respectively provided in the upper and lower clamping portions. The claw portion can respectively hook the frame body from the upper and lower sides of the frame body, thereby preventing the upper bracket and the lower bracket from falling off due to the impact of the blade mechanism when the blade mechanism is operated on the track mechanism, thereby ensuring the blade The smooth running of the mechanism on the upper and lower rails.

In one example, the hook portion is a plate-like member provided with a hook in the clamping portion. Since the hook has a good hooking effect and can ensure the firmness of the plate member, the frame body can be hooked from the upper and lower sides of the frame body to enhance the clamping force of the upper and lower clamping portions on the frame body. , thereby enhancing the connection between the frame and the upper and lower brackets.

In one example, the hook of the plate member includes a horizontal portion that abuts against an outer surface of the frame body, and a bent portion that is continuous with the horizontal portion and encloses the edge of the bead. Thereby, it is ensured that the hook of the plate member can firmly hook the hem of the frame.

In one example, in order to meet the assembly needs in practical applications, the plate-like members are detachably mounted in the clamping portions of the upper and lower brackets, respectively, or are respectively integrated with the clamping portions of the upper and lower brackets. forming.

In one example, when the plate-like members are detachably mounted in the clamping portions of the upper and lower brackets, respectively, the plate-like members may be respectively fixed to the upper and lower clamping portions by a locking member. connection. Therefore, the plate-shaped members can be firmly combined with the upper and lower clamping portions, respectively, so that the hook portions of the upper and lower clamping portions respectively hook the frame side of the photovoltaic panel unit, the upper and lower brackets Can withstand the impact of the scraper mechanism.

In one example, in order to ensure that the locking member has a good locking effect while facilitating the removal and installation of the plate member, the locking member is a bolt or a positioning pin with an external thread.

In one example, the upper surfaces of the upper and lower brackets also respectively define track grooves for mounting the upper rail and the lower rail, and the bottoms of the upper rail and the lower rail are formed for insertion. An insertion portion in the track groove; wherein the groove walls on both sides of the track groove gradually gather from the bottom to the top toward the center of the track groove, and the cross-sectional shape of the insertion portion is the same as the cross-sectional shape of the track groove, And after the insertion portion is inserted into the track groove, the insertion portion is locked and fixed by the groove wall on the track groove side. Since the upper and lower brackets are respectively provided with track grooves, the bottoms of the upper rail and the lower rail have insertion portions, and the groove walls on both sides of the track grooves gradually gather from the bottom to the top toward the center of the track grooves, thereby making the upper rail and the lower rail After the insertion portion is inserted into the track groove, the insertion portions of the upper rail and the lower rail can be locked and fixed by the groove walls on both sides of the track groove, thereby achieving installation between the upper and lower rails and the upper and lower fixing brackets.

In one example, the clamping portion includes a first clamping plate and a second clamping plate that are adapted to clamp the upper and lower sides of the frame; wherein the first clamping plate and the first clamping plate The second clamping plates are arranged parallel to each other. Since the first clamping plate and the second clamping plate are disposed in parallel with each other, the first clamping plate and the second clamping plate can be closely attached to the outer surface of the frame.

detailed description

In order to make the objects, the technical solutions and the advantages of the present invention more clearly, the examples of the embodiments described by the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that in the examples, numerous technical details are set forth in order to provide the reader with a better understanding of the application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and various changes and modifications based on the following examples.

The first example relates to a trolley running mechanism, as shown in FIG. 1, comprising a traction rope 3, a guide rail 2 and a trolley 1 which is moved along the guide rail 2 under the driving of the traction rope 3; wherein the inside of the guide rail 2 is hollow The tubular cavity 21, at least a part of the traction rope 3 is located in the tubular cavity 21, the trolley 1 is connected to the traction rope 3, and the connection portion of the traction rope 3 and the trolley 1 is located in the tubular cavity 21. Wherein, the rail 2 is provided with a strip-shaped hole 23, and the strip-shaped hole 23 is connected to the outside of the tubular cavity 21 and the guide rail 2, The shape of the guide rail 2 can be referred to FIG. On the other hand, the trolley 1 is provided with a connecting arm 11, and the connecting arm 11 penetrates into the tubular cavity 21 through the strip hole 23, and is connected to the pulling rope 3. By connecting the cart 1 and the guide rail 2 to each other by the connecting arm 11, the cart 1 can be made to operate more stably.

In the present example, the connecting arm 11 penetrates the tubular cavity 21 along the central axis of the guide rail 2 in the vertical direction. The connecting arm 11 that penetrates the tubular cavity 21 through the central axis is bilaterally symmetrical due to the force position, and has better stability. Referring to Fig. 1, the connecting arm 11 of this example projects from the top of the guide rail 2 into the tubular cavity 21.

In the present example, the carriage 12 is provided with rollers 12 at positions on both sides of the guide rail 2. The rotation axis of the roller 12 is perpendicular to the table surface on which the guide rail 2 is mounted, and the roller 12 catches the guide rail 2. Specifically, as shown in FIG. 1 , the center of the roller 12 is recessed inwardly to form a recessed portion; the two sides of the guide rail 2 protrude outward to form a protruding portion; the protruding portions on both sides of the guide rail 2 respectively are recessed with the correspondingly disposed roller 12 The departments cooperate with each other. With respect to the technical solution in which the roller 12 is protruded and the guide rail 2 is recessed, the guide rails 2 on both sides in a protruding state can effectively prevent dust from collecting in the guide rail 2, thereby preventing the resistance of the guide rail 2 from increasing and failing.

In an example, the roller 12 of the trolley 1 can also be as shown in FIG. 2, the rotation axis of the roller 12 is parallel to the table surface on which the guide rail 2 is mounted, and the roller 12 is stuck to the guide rail 2, and the guide rail 2 is disposed under the roller 12 at this time. . With respect to the technical solution in which the rotating shaft of the roller 12 is perpendicular to the table top on which the guide rail 2 is mounted, the space required for the guide rail 2 required by the present embodiment is slightly larger. Obviously, there are many ways for the roller 12 to cooperate with the guide rail 2. The specific cooperation manner does not affect the implementation of the basic technical solution of the present example.

In the present example, as shown in FIG. 6, the strip hole 23 may be flush with the guide rail 2 in the longitudinal direction of the guide rail 2, or may be formed to slide through the guide rail 2 together with the tubular cavity 21 as shown in FIG. The groove, the connecting arm 11 is moved along the chute under the driving of the traction rope 3. When the guide rail 2 forms a chute, the trolley 1 can be slid into the guide rail 2 from the outside of the guide rail 2 through the chute, so that maintenance required to disassemble the trolley 1 becomes easier.

In the present example, the bottom of the guide rail 2 is provided with a dovetail groove 24. The dovetail slot 24 facilitates assembly and securing of the rail 2. Obviously, the bottom of the guide rail 2 can also have other designs for conveniently setting the guide rail 2. For example, a screw hole may be reserved at the bottom of the guide rail 2 for the guide rail 2 to be screwed to the mounting platform.

In the present example, the connecting arm 11 can be fixedly connected to the trolley 1 or can be movably or detachably connected to the trolley 1. In contrast, when the connecting arm 11 is detachable, the trolley 1 can be first mounted on the guide rail 2, the connecting arm 11 is connected to the traction rope 3, and then connected to the trolley 1. When the connecting arm 11 is movable, the connecting arm 11 can also be removed to the outside first, and after the loading of the trolley 1, the connecting arm 11 is pivoted back and connected to the pulling rope 3. The detachable or movable connection of the connecting arm 11 can help the trolley 1 to be more easily mounted on the guide rail 2 on the premise that the strip hole 23 does not penetrate the guide rail 2.

With respect to the prior art, the present example solves the problem of rusting of the traction rope 3 in parallel with the guide rail by embedding at least a part of the traction rope 3 in the guide rail 2. With the technical solution provided by the present example, since the rust prevention requirement for the traction rope 3 is omitted, the cost of the traction rope 3 can be greatly reduced.

The second example relates to a trolley running mechanism, and the second example is a further improvement of the first example, the main improvement being that in the second example, the connecting arm 11 projects from the bottom into the tubular cavity 21. As shown in FIG. 3, the connecting arm 11 includes two arms, which respectively bypass the left and right sides of the guide rail 2 and meet at the bottom of the guide rail 2, and the connecting arm 11 penetrates into the tubular cavity from the bottom of the guide rail 2. Body 21.

Since the bottom opening has better dustproof and rainproof effect with respect to the top opening, the two symmetrical arms enable the traction of the traction rope 3 to the body of the trolley 1 to be evenly distributed, which is greatly improved. The stability of the car 1 operation.

In order to facilitate the passage of the connecting arm 11 from the bottom of the guide rail 2, the fixing manner of the guide rail 2 can be adaptively designed. Specifically, the two ends of the guide rail 2 can be respectively fixed on both sides of the table top, so that the guide rail 2 is overhead, or a multi-section trolley 1 can be disposed on one guide rail 2, and each trolley 1 is responsible for one guide rail 2 area, each The guide rail 2 is fixed at the joint of the rail 2 area.

The third example relates to a trolley running mechanism, and the third example is slightly different from the first example, the main difference being that in the first example, the connecting arm 11 penetrates along the central axis of the guide rail 2 in the vertical direction. a tubular cavity 21, such that the strip-shaped aperture 23 is located on the central axis of the guide rail 2 in the vertical direction; In the third example, as shown in FIG. 4 or FIG. 5, the top of the guide rail 2 is formed with a dustproof cymbal 22, and the strip-shaped hole 23 is located below the dust mites 22.

At this time, the connecting arm 11 can be passed around the dust dam 22 and protrude from the lower strip hole 23 into the tubular cavity 21 to be connected to the pulling rope 3. The use of the dust mites 22 not only prevents dust from entering the tubular cavity 21, but also effectively blocks the intrusion of rain and snow, thereby extending the service life of the device.

Further, in this example, see FIG. The strip hole 23 may be located at the shoulder of the guide rail 2, at which time the connecting arm 11 projects into the tubular cavity 21 from the side of the guide rail 2. Under the premise of ensuring the dustproof and waterproof effect, the arrangement can compress the height of the guide rail 2 to a greater extent and improve the stability of the track. Specifically, in this technical solution, as shown in Fig. 4, the lower edge of the strip hole 23 may also be provided with a certain curvature so that water droplets may flow down and down along the arc when it rains.

Alternatively, as shown in Fig. 5, the strip hole 23 may also be located at the waist of the guide rail 2, and the connecting arm 11 projects obliquely upward from the side of the guide rail 2 into the tubular cavity 21. Obviously, when the strip hole 23 is located at the waist of the guide rail 2, rainwater and dust are hard to accumulate in the tubular cavity 21, and thus have a better dustproof and waterproof effect.

The fourth example relates to a trolley running mechanism, and the fourth example is a further improvement of the above three examples, the main improvement being that, in the fourth example, a dustproof top is provided at the edge of the strip hole 23.

Through the dustproof top, it is possible to effectively prevent dust from entering the tubular cavity 21 of the guide rail 2 through the strip hole 23, thereby preventing the guide rail 2 from being ineffective due to dust accumulation. In addition, the dustproof top provides a damping effect on the connecting arm 11, which prevents the trolley 1 from continuously moving due to inertia, resulting in the rope 3 being wound around the rope.

The fifth example relates to a trolley running mechanism, and the fifth example is further improved on the basis of the first example, and the main improvement is that, as shown in FIG. 8, in the present example, the guide rail 2 is provided with a plurality of hollows. The portion 2-1 and the hollow portion 2-1 coincide with the length of the tubular cavity 21. Therefore, it is not difficult to find that by providing a plurality of hollow portions 2-1 in the guide rail 2, it is possible to reduce reliability while ensuring reliability. The weight of the rails makes the rails easier to install.

The sixth example relates to a trolley running mechanism, and the sixth example is further improved on the basis of the third example, the main improvement of which is: in this example, as shown in FIG. 9, the tubular cavity of the guide rail 2 can also be A cap 2-2 for covering the traction rope is provided, and when the strip hole is located at the shoulder of the guide rail 2, the shoulder of the guide rail 2 has a portion extending toward the inside of the tubular cavity to form a cap 2 covering the traction rope 2 2. When the strip hole is located at the waist of the guide rail, the waist portion of the guide rail 2 partially extends toward the inside of the tubular cavity to form a brim 2-2 covering the leash 3. The traction rope 3 located in the tubular cavity can be shielded by the brim 2-2 to prevent the traction rope 3 from being detached from the guide rail 2 during the transmission to ensure stable movement of the trolley on the guide rail.

The seventh example relates to a cleaning device using any of the above-described various types of carriage running mechanisms. In the fifth example, as shown in FIG. 10, the cleaning device further includes a traction mechanism 4 for providing a power source. And a protective sleeve 5 for protecting the traction rope 3, wherein the traction rope 3 protrudes from both ends of the guide rail 2 and is connected with the traction mechanism 4, and the protection sleeve 5 is disposed between the traction mechanism 4 and the guide rail 2 to protect The sleeve 5 encloses a traction rope 3 at least partially located between the traction mechanism 4 and the guide rail 2.

The protective sleeve 5 can effectively prevent the traction rope 3 from being exposed to the air and being rusted by the influence of wind, sand and rain.

In an example shown in Fig. 10, in order to facilitate the installation of the traction device, the cleaning device further includes a guide pulley 6 for changing the direction of movement of the traction rope 3. Further, the protective sleeve 5 may also include a guide wheel guard sleeve that is sleeved around the guide wheel 6 and communicates with other portions of the protective sleeve 5 such that the traction rope 3 is completely Protect it. Specifically, the guide wheel cover can also be detachably connected with the rest of the protective sleeve 5, thereby reducing maintenance costs and improving disassembly efficiency.

In the example shown in Fig. 10, there are two traction mechanisms 4, and the two traction mechanisms 4 are respectively connected to both ends of the traction rope 3. Obviously, the traction mechanism 4 can also be provided with two reeling machines The same traction mechanism. When the traction mechanism 4 is one, both ends of the traction rope 3 are simultaneously connected to the traction mechanism 4. Moreover, in order to provide a stronger traction force, a plurality of traction mechanisms may be connected in parallel and connected to the traction rope 3.

Obviously, some embodiments of the present invention can be applied not only to the unique application scenario of a photovoltaic power station, but also to other fields that may require the use of a trolley operating mechanism.

The eighth example relates to a track mechanism of a photovoltaic panel cleaning device, as shown in Figs. 11 and 12, which includes an upper rail 31-1 and a lower rail 31-2 which are respectively disposed on upper and lower sides of the photovoltaic panel unit 34. The frame body 33 is covered around the photovoltaic panel unit 34, and the upper and lower sides of the frame body 33 are bent inward to form a hem that encloses the photovoltaic panel unit 34.

Wherein, the track mechanism of the photovoltaic panel cleaning device further comprises an upper bracket 32-1 for fixing the upper rail 31-1 and a lower bracket 32-2 for fixing the lower rail 31-2, and the upper and lower brackets respectively have a function for clamping the photovoltaic The panel unit 34 has an upper clamping portion 35-1 and a lower clamping portion 35-2 of the frame 33. Further, hook portions 38 that hook the frame body 33 are provided in the upper and lower clamping portions.

It is not difficult to find through the above that, in the track mechanism of the photovoltaic panel cleaning device, the upper bracket 32-1 for fixing the upper rail 31-1 and the lower bracket 32-2 for fixing the lower rail 31-2 have upper and lower clips, respectively. The holding portion has a hook portion 38 in the upper and lower clamping portions, respectively, and can hook the rim of the frame 33 from the upper and lower sides of the frame 33, thereby preventing the blade mechanism (not shown) When running on the rail mechanism, the upper bracket 32-1 and the lower bracket 32-2 are detached by the impact of the scraper mechanism, thereby ensuring smooth running of the scraper mechanism on the upper rail 31-1 and the lower rail 31-2.

Specifically, in the present example, in order to enable the blade mechanism to perform normal sliding in the track mechanism, as shown in FIG. 12, the upper surface of the upper bracket 35-1 of the track mechanism is separately opened for mounting the upper rail 31-1. The track grooves 36, and the bottoms of the upper rails 31-1 and the lower rails 31-2 form insertion portions 310 (not shown) for insertion into the track grooves 36. Wherein, the groove walls on both sides of the track groove 36 gradually merge from the bottom to the top toward the center of the track groove 36, and the cross-sectional shape of the insertion portion 310 is the same as the cross-sectional shape of the track groove 36, and after the insertion portion 310 is inserted into the track groove 36, The insertion portion 310 is locked and fixed by the groove wall on the side of the track groove 36. The lower bracket 35-2 also uses the same knot Structure.

It can be seen that since the upper and lower brackets are respectively provided with the track grooves 36, the bottoms of the upper rails 31-1 and the lower rails 31-2 have the insertion portions 310, and the groove walls on both sides of the track grooves 36 gradually move from the bottom to the top. The center of the groove 36 is gathered such that the insertion portion 310 of the upper rail 31-1 and the lower rail 31-2 can pass through the groove walls on both sides of the track groove 36 to the upper rail 31-1 and the lower rail after being inserted into the rail groove 36. The insertion portion 310 of 31-2 is locked and fixed, thereby achieving installation between the upper and lower rails and the upper and lower fixing brackets.
