Description

Power signage quick locking signage holder

technical field

The invention relates to a fast locking sign frame for electric signs.

Background technique

With the accelerated pace of urban construction, the length of transmission lines is also increasing year by year. The angle steel tower has the advantages of small plate pressure drop, large gas phase flux, good tray efficiency, simple structure, and convenient processing and manufacturing. Therefore, angle steel towers have been widely used in the erection of transmission lines now.

According to the regulations, power line towers should be marked with line names, pole (tower) numbers, color codes, warning signs and other signs, and these signs need to be fixed on the poles and towers through fixing frames. In the past, signs such as pole number plates and warning signs were generally bound on the pole tower with iron wires, or fixed on the main materials on both sides of the angle steel tower with flat steel brackets. Due to the effect of wind, the influence of flying birds and the defects of the fixing method, it is very easy to cause the bracket to be distorted and fall off and deformed. Through the investigation and analysis of the loss of signboards, the number of missing signboards due to corrosion accounted for at least 4.1% of the total number of losses, the number of lost signs due to deformation of the signboard frame accounted for 77.3%, and the number of standard plates lost due to the loss of fixing bolts of the card frame accounted for 18.6% %.

During use, when the signboard is distorted or deformed, it needs to be maintained in time, and if the damage is serious, it needs to be replaced in time to ensure the eye-catching and effective signboard.

Contents of the invention

The purpose of the present invention is to solve the above technical problems, to provide a fast locking power signage with reasonable structure, convenient installation, firm fixation, convenient disassembly or maintenance, and help to improve work efficiency.

In order to solve the above-mentioned technical problems, the structural features of the present invention are as follows: it includes a card frame fastened together with the signboard by fasteners, the card frame is fixed with an upper plate and a lower plate arranged in parallel up and down and extending horizontally, and the upper plate Longer than the lower plate, the end of the upper plate is provided with an upper hole, and the upper hole is inserted with a clamping bolt, and a clamping groove is formed between the upper plate and the lower plate to accommodate the angle steel cross-arm, and the end of the lower plate is hinged by a hinge shaft to connect the upper and lower For the swinging swing rod, the middle part of the swing rod is fixed with an outwardly extending side pressure plate and an upper pressure plate, and the end of the swing rod is fixed with a locking plate corresponding to the end of the upper plate. Locking hole, when the locking plate swings to the bottom of the upper plate end and is locked with the upper plate by snap-fitting bolts, the side pressure plate is tightly fitted with the vertical and straight plates of the angle steel cross arm, and the upper pressure plate is pressed tightly with the horizontal and straight plates of the angle steel cross arm Cooperate.

The power signage fast locking signboard is easy to install, securely fixed, and easy to disassemble or maintain through the surrounding screw-joint locking structure.

The surrounding screw locking structure mainly includes an upper plate and a lower plate fixed on the card frame, the upper plate and the lower plate are arranged perpendicular to the plane of the card frame, and the upper plate and the lower plate are arranged in parallel and at intervals, so that the upper plate and the lower plate are arranged at intervals. A cavity, i.e. clamping groove, is formed between the lower plates. The height of the clamping groove is slightly higher than that of the angle steel cross-arm, so that the clamping groove can be smoothly and quickly snapped onto the angle steel cross-arm. One of the functions of the clip groove is to hold the angle steel cross-arm. For the convenience of description, the two plate surfaces constituting the cross-arm of the angle steel are defined, the horizontal plate surface is defined as the horizontal plate, the vertical plate surface is defined as the vertical plate, and the space semi-enclosed by the horizontal plate and the vertical plate is defined as The inner cavity is defined, and one side surrounded by the horizontal straight plate and the vertical straight plate is defined as the inner cavity, and the other side is defined as the outer cavity. In the fast locking sign holder for electric signage, the length of the upper plate is longer than that of the lower plate, which is mainly for better cooperation with the angle steel cross-arm structure. In the design of power angle steel towers, the angle steel cross arms are generally arranged with horizontal and vertical plates on the top and vertical plates below, and the horizontal and straight plates are arranged horizontally, and the vertical and vertical plates are arranged vertically. Therefore, the main purpose of setting the upper plate longer than the lower plate is to enable the upper plate to match the width of the horizontal and straight plates, and to enable the length of the lower plate to match the thickness of the vertical and straight plates. In the fast locking card holder for electric signage, a swing rod is hinged to the end of the lower plate through a hinge shaft, and the swing rod can swing up and down around the hinge shaft. A locking plate is fixed at the end of the swing rod, and a side pressure plate and an upper pressure plate are fixed at the middle of the swing rod. When the fast locking frame of the electric signage is clamped on the angle steel cross arm, that is, when the angle steel cross arm is snapped into the clamping groove, the swing rod is swung upward, and the side pressure plate will gradually move toward the vertical straight plate under the push of the swing rod. Approaching, the upper pressing plate will approach the horizontal straight plate under the push of the swing rod, and at the same time the locking plate will gradually approach the end of the upper plate. When the locking plate swings to the bottom of the upper plate end, the side pressing plate is just in time against the vertical straight plate, and the upper pressing plate is just in time against the horizontal straight plate. For convenience of description, this state is referred to as the state to be locked. An upper hole is arranged at the end of the upper plate, and a locking hole is arranged on the locking plate. When the lock is to be locked, the upper hole and the locking hole are set correspondingly up and down. The power signage fast locking card frame also includes snap bolts that are inserted and matched with the upper hole and the locking hole. One of the main functions of the snap bolt is to insert into the upper hole and the locking hole when it is to be locked The locking plate and the upper plate are fixed and locked together. When the clamping bolt locks the upper plate and the locking plate, the side pressure plate on the swing rod will also press the vertical straight plate of the angle steel cross arm to the side of the card frame, and the upper pressure plate on the swing rod will also press the angle steel cross arm The horizontal straight plate is pressed to the bottom of the upper plate, so the function of pressing or locking in two directions at the same time is realized by one bolt. For the convenience of description, this state is called the locked state.

In the locked state, the angle steel cross arm is limited upward by the upper plate, that is, the outside of the horizontal straight plate is limited downward by the upper plate, and the angle steel cross arm is limited downward by the lower plate and the upper pressure plate, that is, the horizontal straight plate The inner side is limited upward by the upper pressing plate, the bottom of the vertical straight plate is limited upward by the lower plate, the outer side of the vertical straight plate is limited by the card frame, and the inner side of the vertical straight plate is limited by the pressing block. That is to say, the angle steel cross arm is subjected to the limit action in the four directions of up, down, left and right. From the direction of reaction, the fast locking frame of the electric signage is also affected by the angle steel cross arm up, down, left and right. , Right four directions of the limit, to ensure that the power sign fast locking card frame is reliably fixed on the angle steel cross-arm.

As an improvement, the clamping bolts are sequentially inserted into the upper hole and the locking hole according to the fixing cap facing upward and the stud facing downward, the nut is tightened on the stud below the locking plate, and the lower end of the stud is connected to the lower plate Face flush.

After long-term use, due to the impact of wind and rain, the nuts at the bottom of the clamping bolts will loosen or even fall off. Since the clamping bolts are sequentially inserted into the upper hole and the locking hole and lock the nuts in such a way that the fixing caps face upwards and the studs face down, after the nuts at the bottom of the clamping bolts fall off, due to the force of the fixing caps of the clamping bolts, The limit effect and the gravity effect of the fixed cap and the snap bolt stud, the snap bolt stud will always be inserted into the upper hole and the locking hole, unless the stud is pushed out of the upper hole and the locking hole by an external force from bottom to top. Locking the hole is obviously impossible under natural conditions. Since the locking plate and the swing rod can only swing around the hinge shaft, that is to say, the swing rod and the locking plate, side pressure plate and upper pressure plate affixed to the swing rod will swing down around the hinge shaft, except that there is a vertical downward swing. The displacement also needs to have a lateral outward swing displacement. Obviously, the lateral outward swing is limited by the studs. Therefore, in the natural state, the swing rod and the locking plate, side pressure plate and upper pressure plate fixed on it cannot fall off. Down, it will still maintain a locked state or a state close to the locked state. And because the length of the stud makes its lower end flush with the upper surface of the lower plate, that is, the length of the stud is long enough to fundamentally ensure that the stud cannot escape from the locking hole under natural force, and it is fundamentally guaranteed The swing rod and the locking plate, side pressing plate and upper pressing plate fixed on it will always keep locked, which fundamentally guarantees the reliability of the installation of the fast locking sign frame of the electric signage.

As a further improvement, when the locking plate swings below the end of the upper plate, it is arranged parallel to and spaced apart from the upper plate.

When the locking plate swings below the end of the upper plate, that is, when it is in the state to be locked, the locking plate and the upper plate are set parallel to each other, so that the upper hole and the locking hole can be aligned up and down, which is convenient for clamping the bolts The studs are inserted smoothly, which helps to improve construction efficiency. A gap is provided between the locking plate and the upper plate, so that the clamping bolts can have a locking space or room for locking the upper plate and the locking plate, thereby ensuring the locking effect and the reliability of the installation.

As an implementation, the card holder includes two vertical boards arranged symmetrically at intervals, and the upper and lower ends of the vertical boards are respectively fixed together by a horizontal board. There are two groups of boards and lower boards, which are respectively fixed on two vertical boards. Fastening holes are evenly distributed on the vertical boards and horizontal boards, and fastening bolts are arranged in the fastening holes.

Because the two vertical plates are arranged in parallel in the vertical direction, and the two horizontal plates are arranged in parallel in the horizontal direction, so the card frame surrounded by the vertical plates and the horizontal plates is a rectangular frame structure, and the structure is simple and firm. The board surfaces of the vertical board and the horizontal board are in the same plane, so that the sign board can be easily attached to it and help to achieve a firm connection. Corresponding fastening holes are arranged on the vertical plate, the horizontal plate and the signboard, and fastening bolts are arranged in the fastening holes, so that the signboard can be fixedly installed on the signboard, and the operation is simple. There are two groups of upper boards and lower boards, which are respectively fixed on two vertical boards, so that the entire card holder and the angle steel crossarm have two fixed locking points, which greatly improves the reliability of installation.

As an improvement, it also includes a compression ring corresponding to the edge of the card frame, and the compression ring is provided with a compression hole corresponding to the fastening hole.

After the compression ring is provided, the compression ring can apply the fastening force of the fastening bolts to the periphery of the signboard, and play the role of assisting the fastening bolts to compress the signboard. In this way, when the signboard is fastened to the card frame, the fastening bolts can be inserted into the compression holes on the compression ring first, and then inserted into the fastening holes on the signboard and the card frame in turn. Finally, tighten the nut to realize the stable connection between the sign board and the board frame, and the operation is very simple.

As a further improvement, a strut is connected between the middle part of the upper plate and the upper end of the card holder.

After setting up the struts, the struts, vertical plates, and upper plates roughly form a triangular frame structure. According to the principle of triangular stability, this triangular frame structure has extremely strong stability, which can ensure that the upper plate is in the triangular frame structure. It will not move relative to the card frame in the plane, which greatly enhances the vertical connection relationship between the vertical plate and the upper plate, and also ensures the structural stability of the card frame on the power angle steel tower, and will not be deformed even if it is blown by strong wind.

To sum up, the fast locking frame for electric power signs has a reasonable structure, convenient and fast installation, and firm fixation. Even if the nuts become loose or even fall off due to wind and rain after long-term use, they will not be separated from the angle steel tower. Long service life, safe and reliable, easy to disassemble or maintain, especially suitable for batch installation and use in engineering projects, which helps to improve work efficiency.

As shown in the figure, the fast locking card holder for electric signage includes a card holder 2 fastened together with the signboard 1 by fasteners. The upper board 3 and the lower board, which are arranged in parallel up and down and extend horizontally, are fixed on the board holder. 4. The upper plate is longer than the lower plate. There is an upper hole 21 at the end of the upper plate, and a snap bolt 22 is inserted in the upper hole. A clamping groove 6 for accommodating the angle steel cross-arm 5 is formed between the upper plate and the lower plate. The lower plate The end part is hinged with a swing rod 8 that swings up and down through the hinge shaft 7. The middle part of the swing rod is fixed with a side pressure plate 9 and an upper pressure plate 10 extending outward. The end of the swing rod is fixed with a locking plate 23 corresponding to the end of the upper plate. , the locking plate is provided with locking holes 24 corresponding to the upper and lower holes. When the locking plate swings to the bottom of the upper plate end and is locked with the upper plate by clamping bolts, the vertical and straight plates 25 of the side pressure plate and the angle steel cross arm Compression fit, the horizontal straight plate 26 compression fit of upper pressing plate and angle steel cross arm.

Both the upper plate and the lower plate are arranged perpendicular to the plane of the card holder, and the upper plate and the lower plate are arranged in parallel and spaced apart, so that a cavity, that is, a clamping groove, is formed between the upper plate and the lower plate. The height of the clamping groove is slightly higher than that of the angle steel cross-arm, so that the clamping groove can be smoothly and quickly snapped onto the angle steel cross-arm. One of the functions of the clip groove is to hold the angle steel cross-arm. For the convenience of description, the two plate surfaces constituting the cross-arm of the angle steel are defined, the horizontal plate surface is defined as the horizontal plate, the vertical plate surface is defined as the vertical plate, and the space semi-enclosed by the horizontal plate and the vertical plate is defined as The inner cavity is defined, and one side surrounded by the horizontal straight plate and the vertical straight plate is defined as the inner cavity, and the other side is defined as the outer cavity. In the fast locking sign holder for electric signage, the length of the upper plate is longer than that of the lower plate, which is mainly for better cooperation with the angle steel cross-arm structure. In the design of power angle steel towers, the angle steel cross arms are generally arranged with horizontal and vertical plates on the top and vertical plates below, and the horizontal and straight plates are arranged horizontally, and the vertical and vertical plates are arranged vertically. Therefore, the main purpose of setting the upper plate longer than the lower plate is to enable the upper plate to match the width of the horizontal and straight plates, and to enable the length of the lower plate to match the thickness of the vertical and straight plates. In the fast locking card holder for electric signage, a swing rod is hinged to the end of the lower plate through a hinge shaft, and the swing rod can swing up and down around the hinge shaft. A locking plate is fixed at the end of the swing rod, and a side pressure plate and an upper pressure plate are fixed at the middle of the swing rod. When the fast locking frame of the electric signage is clamped on the angle steel cross arm, that is, when the angle steel cross arm is snapped into the clamping groove, the swing rod is swung upward, and the side pressure plate will gradually move toward the vertical straight plate under the push of the swing rod. Approaching, the upper pressing plate will approach the horizontal straight plate under the push of the swing rod, and at the same time the locking plate will gradually approach the end of the upper plate. When the locking plate swings to the bottom of the upper plate end, the side pressing plate is just in time against the vertical straight plate, and the upper pressing plate is just in time against the horizontal straight plate. For convenience of description, this state is referred to as the state to be locked. An upper hole is arranged at the end of the upper plate, and a locking hole is arranged on the locking plate. When the lock is to be locked, the upper hole and the locking hole are set correspondingly up and down. The power signage fast locking card frame also includes snap bolts that are inserted and matched with the upper hole and the locking hole. One of the main functions of the snap bolt is to insert into the upper hole and the locking hole when it is to be locked The locking plate and the upper plate are fixed and locked together. When the clamping bolt locks the upper plate and the locking plate, the side pressure plate on the swing rod will also press the vertical straight plate of the angle steel cross arm to the side of the card frame, and the upper pressure plate on the swing rod will also press the angle steel cross arm The horizontal straight plate is pressed to the bottom of the upper plate, so the function of pressing or locking in two directions at the same time is realized by one bolt. For the convenience of description, this state is called the locked state.

In the locked state, the angle steel cross arm is limited upward by the upper plate, that is, the outside of the horizontal straight plate is limited downward by the upper plate, and the angle steel cross arm is limited downward by the lower plate and the upper pressure plate, that is, the horizontal straight plate The inner side is limited upward by the upper pressing plate, the bottom of the vertical straight plate is limited upward by the lower plate, the outer side of the vertical straight plate is limited by the card frame, and the inner side of the vertical straight plate is limited by the pressing block. That is to say, the angle steel cross arm is subjected to the limit action in the four directions of up, down, left and right. From the direction of reaction, the fast locking frame of the electric signage is also affected by the angle steel cross arm up, down, left and right. , Right four directions of the limit, to ensure that the power sign fast locking card frame is reliably fixed on the angle steel cross-arm.

In the power signage fast locking card holder, the clamping bolts 22 are sequentially inserted into the upper hole 21 and the locking hole 24 according to the fixing cap 27 facing upward and the stud 28 facing downward, and the nut 29 is tightened on the locking plate 23 on the stud below, and the lower end of the stud 28 is flush with the lower plate surface. After long-term use, due to the impact of wind and rain, the nuts at the bottom of the clamping bolts will loosen or even fall off. Since the clamping bolts are sequentially inserted into the upper hole and the locking hole and lock the nuts in such a way that the fixing caps face upwards and the studs face down, after the nuts at the bottom of the clamping bolts fall off, due to the force of the fixing caps of the clamping bolts, The limit effect and the gravity effect of the fixed cap and the snap bolt stud, the snap bolt stud will always be inserted into the upper hole and the locking hole, unless the stud is pushed out of the upper hole and the locking hole by an external force from bottom to top. Locking the hole is obviously impossible under natural conditions. Since the locking plate and the swing rod can only swing around the hinge shaft, that is to say, the swing rod and the locking plate, side pressure plate and upper pressure plate affixed to the swing rod will swing down around the hinge shaft, except that there is a vertical downward swing. The displacement also needs to have a lateral outward swing displacement. Obviously, the lateral outward swing is limited by the studs. Therefore, in the natural state, the swing rod and the locking plate, side pressure plate and upper pressure plate fixed on it cannot fall off. Down, it will still maintain a locked state or a state close to the locked state. And because the length of the stud makes its lower end flush with the upper surface of the lower plate, that is, the length of the stud is long enough to fundamentally ensure that the stud cannot escape from the locking hole under natural force, and it is fundamentally guaranteed The swing rod and the locking plate, side pressing plate and upper pressing plate fixed on it will always keep locked, which fundamentally guarantees the reliability of the installation of the fast locking sign frame of the electric signage.

In this embodiment, when the locking plate 23 swings below the end of the upper plate 3 , it is arranged parallel to and spaced from the upper plate. When the locking plate swings below the end of the upper plate, that is, when it is in the state to be locked, the locking plate and the upper plate are set parallel to each other, so that the upper hole and the locking hole can be aligned up and down, which is convenient for clamping the bolts The studs are inserted smoothly, which helps to improve construction efficiency. A gap is provided between the locking plate and the upper plate, so that the clamping bolts can have a locking space or room for locking the upper plate and the locking plate, thereby ensuring the locking effect and the reliability of the installation.

The card holder 2 includes two vertical plates 11 arranged symmetrically at intervals, and the upper and lower ends of the vertical plates are fixedly connected together by a horizontal plate 12 respectively. The number of plates is two groups, which are respectively fixed on two vertical plates. Fastening holes 13 are evenly distributed on the vertical plates and the horizontal plates, and fastening bolts 14 are arranged in the fastening holes. Because the two vertical plates are arranged in parallel in the vertical direction, and the two horizontal plates are arranged in parallel in the horizontal direction, so the card frame surrounded by the vertical plates and the horizontal plates is a rectangular frame structure, and the structure is simple and firm. The board surfaces of the vertical board and the horizontal board are in the same plane, so that the sign board can be easily attached to it and help to achieve a firm connection. Corresponding fastening holes are arranged on the vertical plate, the horizontal plate and the signboard, and fastening bolts are arranged in the fastening holes, so that the signboard can be fixedly installed on the signboard, and the operation is simple. There are two groups of upper boards and lower boards, which are respectively fixed on two vertical boards, so that the entire card holder and the angle steel crossarm have two fixed locking points, which greatly improves the reliability of installation.

The fast locking card holder for electric signs also includes a compression ring 15 corresponding to the edge of the card holder 2, and a compression hole 16 corresponding to the fastening hole 13 is provided on the compression ring.
