Description

Technical Field

[0001] The utility model relates to the technical field of cable or wire installation, in particular to a row of cards that can be used with a nail gun and a staple gun. Background Art

[0002] The row of cards is usually used for arranging the pipeline, and can provide additional support and protection for the pipeline. Generally, the row of cards is fixed on the ground or wall by nails. The traditional way to fix the row of cards is to drive the nails into the steel nail holes of the row of cards through a nail gun device (pneumatic nail gun or electric nail gun) to fix the row of cards on the wall. However, due to the large volume of the nail gun device, it is very inconvenient to carry. Therefore, more and more electricians now choose to use a nail gun to fix the row of cards. Compared with the traditional nail gun device, the nail gun has many advantages. It gets rid of the cumbersome wires and air ducts of the nail gun device, has a small volume, and is fast in operation, greatly improving the construction efficiency. However, the traditional row of cards only has a steel nail hole adapted to the nail gun device, and this hole is only for fixing by the nail gun device or manually driving steel nails. When using a nail gun, it is necessary to align the nail shooting port of the nail gun with the steel nail hole of the row of cards, and the steel nail is used to fix the row of cards on the wall through the push of gunpowder gas. However, the steel nail holes on the market are relatively small and cannot be aligned with the nail shooting holes of the nail gun, and it is easy to cause the row of cards to break when using a nail gun. The Chinese patent document with the publication date of February 10, 2023 and the publication number of CN218472715U discloses a row of cards for fixing pipelines, belonging to the technical field of wire installation accessories. It solves the problem that the intervals between adjacent fixing clamps are separated, and it is easy to have the problem of clamping loosening. The row of cards for fixing pipelines includes a bottom plate, and annular clamps are arranged in sequence on the bottom plate. An opening is arranged at the top of the annular clamp, and an assembly groove is arranged on the inner wall of the bottom of the annular clamp opposite to the opening. A connecting hole penetrating the bottom plate is arranged at the bottom of the assembly groove. A strengthening structure for connecting the two adjacent annular clamps is arranged between the two adjacent annular clamps; the two adjacent annular clamps are connected into one body through the strengthening structure. However, the steel nail holes of this row of cards are relatively small and are only suitable for nail gun devices such as pneumatic nail guns or electric nail guns. When using a nail gun to fix the row of cards, the row of cards is very easy to break. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problem that the existing row of cards is only suitable for nail gun devices such as pneumatic nail guns or electric nail guns, and provide a row of cards that can be used with a nail gun and a staple gun, which can not only be fixed by a nail gun device such as a pneumatic nail gun or an electric nail gun, but also be fixed by a nail gun, and has the characteristics of convenient and fast fixing operation and high construction efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will further illustrate the specific embodiments of the technical solution of the present utility model through examples in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] In Figure 1 Figure 2 Figure 3In the shown Embodiment 1, a row card for a nail gun and a staple gun is provided. The row card is made of plastic and includes a long strip-shaped bottom plate 1. Eight card seats 2 arranged in a straight line are integrally provided on the bottom plate 1. A fixed card 3 with an upward-facing bayonet is provided on the card seat 2. A nail hole penetrating through the card seat 2 and the bottom plate 1 is provided at the center of the bottom of the fixed card 3 (see Figure 4 Figure 5 ). The nail hole includes a bottom hole 4 and a nail gun hole 5 adapted to the muzzle of the nail gun. Above the nail gun hole 5, a nail gun hole 6 adapted to the muzzle of the nail gun is provided. The row card is usually used to arrange wire pipes and can provide additional support and protection for the wire pipes. Generally, the row card is fixed to the ground or wall by nails. The traditional way to fix the row card is to drive nails into the steel nail hole of the row card through a nail gun device (pneumatic nail gun or electric nail gun) to fix the row card to the wall. However, due to the large volume of the nail gun device, it is very inconvenient to carry. Therefore, more and more electricians now choose to use a nail gun to fix the row card. Compared with the traditional nail gun device, the nail gun has many advantages. It gets rid of the cumbersome wires and air ducts of the nail gun device, has a small volume, and can be operated quickly, greatly improving the construction efficiency. However, the traditional row card only has a steel nail hole adapted to the nail gun device. This hole is only for fixing by the nail gun device or manually driving steel nails. When using a nail gun, it is necessary to align the nail shooting port of the nail gun with the steel nail hole of the row card, and the steel nail is used to fix the row card to the wall by the push of gunpowder gas. However, the steel nail holes on the market are relatively small and cannot be aligned with the nail shooting hole of the nail gun, and it is easy to cause the row card to break when using the nail gun.

[0026] The bottom plate 1 of the present utility model is in a long strip shape, and eight card seats 2 are integrally provided on it. These card seats 2 are arranged in a straight line. A fixed card 3 is provided on each card seat 2. The bayonet of the fixed card 3 faces upward and is used to fix wire pipes and the like that need to be neatly arranged. There is a nail hole at the center of the bottom of the fixed card 3. This nail hole penetrates through the entire card seat 2 and the bottom plate 1. The nail hole includes a bottom hole 4 and a nail gun hole 5. The nail gun hole 5 is adapted to the muzzle of the nail gun. When the operator uses a nail gun device (pneumatic nail gun or electric nail gun), the nail gun hole 5 is used to fix the steel nail driven by the nail gun device. In addition, a nail gun hole 6 is provided above the nail gun hole 5 of the present utility model. The nail gun hole 6 is adapted to the muzzle of the nail gun. The operator can also use a nail gun device, and the nail gun hole 6 is used to fix the steel nail driven by the nail gun device. This design allows different types of nail guns (nail gun or nail gun) to be used to fix the row card, providing flexibility and convenience, and greatly facilitating the operator. In this way, the present utility model solves the problem that the existing row card is only applicable to nail gun devices such as pneumatic nail guns or electric nail guns. The row card of the present utility model can not only be fixed by nail gun devices such as pneumatic nail guns or electric nail guns, but also can be fixed by a nail gun. It has the characteristics of convenient and fast fixing operation and high construction efficiency, showing innovation design and technological progress in the row card.

[0027] The bottom hole 4 of this embodiment is located on the bottom plate 1, that is, the position of the bottom hole 4 is on the bottom plate 1 and its depth is equivalent to the thickness of the bottom plate 1; the nail gun hole 5 is located on the card holder 2, that is, the position of the nail gun hole 5 is on the card holder 2 and its depth is equivalent to the height of the card holder 2; the powder-actuated nail gun hole 6 is located at the joint of the card holder 2 and the fixed clamp 3. The bottom hole 4, the nail gun hole 5 and the powder-actuated nail gun hole 6 form a stepped shaft structure that is larger at the top and smaller at the bottom. The stepped shaft structure formed by the bottom hole 4, the nail gun hole 5 and the powder-actuated nail gun hole 6 on the row of cards bottom plate 1 can improve the practicability and durability of the row of cards. The design of the bottom hole 4, the nail gun hole 5 and the powder-actuated nail gun hole 6 can adapt to different types of nail guns, increasing the versatility and multi-functionality of the row of cards. The stepped shaft structure design on the row of cards bottom plate 1 not only provides convenience and flexibility in operation, but also may enhance its performance and durability in actual use, ensuring the stability when the row of cards is fixed.

[0028] The card holder 2 of this embodiment is cylindrical, and the fixed clamp 3 is integrally in the shape of an open-top circular ring. The circular ring surface of the fixed clamp 3 on the card holder 2 is in the same vertical plane. The cylindrical card holder 2 is convenient for setting the circular nail gun hole 5 and the powder-actuated nail gun hole 6, so that the bottom hole 4, the nail gun hole 5 and the powder-actuated nail gun hole 6 form a stepped shaft structure that is larger at the top and smaller at the bottom. Since the outer wall thickness of the nail gun hole 5 and the powder-actuated nail gun hole 6 is uniform, it will not crack due to uneven stress after being impacted during operation. At the same time, the cylindrical card holder 2 and the circular fixed clamp 3 provide a better contact area and stability, helping to fix objects more firmly. The design of the cylindrical card holder 2 and the circular fixed clamp 3 may provide better structural strength and durability, helping to bear greater forces and weights. This row of cards design provides stability, easy installation, aesthetics and high structural strength through its cylindrical card holder 2 and circular fixed clamp 3.

[0029] The fixed clamp 3 of this embodiment includes two arc-shaped cards 13 (see Figure 6 ), which are symmetrically arranged. The width of the card 13 is smaller than the outer diameter of the card holder 2, and the width of the bottom plate 1 is larger than the outer diameter of the card holder 2. The arc-shaped cards 13 provide better flexibility and adaptability, can adapt to objects of different shapes and sizes, and are convenient for fixing and unloading. The width of the card 13 is smaller than the outer diameter of the card holder 2. This design can ensure the structural stability of the row of cards is improved, and the card 13 is stably fixed on the card holder 2; the width of the bottom plate 1 is larger than the outer diameter of the card holder 2, which increases the stability and load-bearing capacity of the bottom plate 1 and also helps to improve the strength of the entire row of cards structure. The symmetrical arrangement of the two arc-shaped cards 13 helps to evenly distribute the load, reducing material fatigue or damage caused by uneven load; the symmetrical design is more balanced and beautiful visually, helping to improve the appearance quality of the product; the design of the arc-shaped cards 13 is convenient for installation and adjustment, and can quickly fix or release objects as needed. The design of the fixed clamp 3 allows a certain degree of bending or deformation to adapt to objects of different shapes, increasing the versatility and flexibility of the row of cards.

[0030] In this embodiment, a connecting plate 9 extends between the two cards 13 of the fixed card 3 and the bottom plate 1. The upper end of the connecting plate 9 is located in the middle of the card 13, and the lower end is integrally connected to the bottom plate 1. A cavity 10 is formed between the connecting plate 9 and the card holder 2. The two cards 13 of the fixed card 3 are connected to the bottom plate 1 through the connecting plate 9. This design creates a cavity 10 in the structure. The upper end of the connecting plate 9 is located in the middle of the card 13, and the lower end is integrally connected to the bottom plate 1. Such a structure helps to improve the overall stability and bearing capacity; the cavity 10 formed between the connecting plate 9 and the card holder 2 can provide additional support and strength for the card arrangement. The cavity 10 design can also reduce the use of materials and reduce weight. The integrated connection design simplifies the production process and helps to improve production efficiency. In addition, the existence of the cavity 10 may help to distribute stress more evenly, reduce local stress concentration, and help to improve the overall mechanical properties, thereby increasing the service life of the card arrangement.

[0031] In this embodiment, the holder 2 and the fixing card 3 on the bottom plate 1 are arranged at equal intervals. The equal interval arrangement provides a neat and orderly appearance for the wire tube after installation, which helps to improve the overall aesthetics of the product; at the same time, the equal interval arrangement helps to distribute the fixed load more evenly, reduce local stress concentration, and improve the stability and durability of the card arrangement; in addition, the equal interval arrangement makes the installation process more standardized and procedural, which helps to improve installation efficiency and accuracy; the equal interval arrangement makes it easier to maintain and replace the fixing card 3, which helps to simplify the maintenance process. The equal interval arrangement helps to standardize the production process, reduce production costs, and improve production efficiency.

[0032] In this embodiment, block-shaped reinforcing ribs 7 are provided between adjacent fixed cards 3, the width of the reinforcing ribs 7 is smaller than the outer diameter of the card seat 2, and the height of the reinforcing ribs 7 is equivalent to the height of the card seat 2. The reinforcing ribs 7 connect adjacent fixed cards 3 together, which is conducive to improving the structural strength of the fixed cards 3. The width of the reinforcing ribs 7 is smaller than the outer diameter of the card seat 2, which helps to maintain the overall coordination and aesthetics, while reducing the use of materials and reducing costs. The height of the reinforcing ribs 7 is equivalent to the height of the card seat 2, which can ensure that the reinforcing ribs 7 can effectively work with the card seat 2 to provide the necessary support and strength. The main function of the reinforcing ribs 7 is to enhance the strength and rigidity of the product without increasing the additional wall thickness, and at the same time help prevent stress concentration caused by the difference in wall thickness of the card row, disperse stress, and reduce stress concentration by transferring stress from high stress areas to surrounding areas, so as to avoid the bottom plate 1 of the card row from breaking between two adjacent fixed cards 3.

[0033] In this embodiment, a connection mechanism is provided at both ends of the card arrangement, and the connection mechanism includes a card slot 11 provided at one end of the card arrangement and a buckle 12 provided at the other end of the card arrangement (see Figure 2 Figure 3), the card slots 11 and the buckles 12 are both vertically arranged; the length of the connecting mechanism is the same as that of the reinforcing rib 7. In this embodiment, the connecting mechanisms at both ends of the row of cards adopt the design of dovetail-shaped card slots 11 and dovetail-shaped buckles 12, making the connection of the row of cards more firm and not prone to displacement or loosening; the vertical arrangement of the dovetail-shaped card slots 11 and dovetail-shaped buckles 12 provides a stable connection method. This design allows for quick and easy assembly and disassembly of the row of cards without the use of additional tools or fasteners, improving the efficiency of installation and maintenance; the dovetail groove connection method has the advantage of strong durability. At the same time, due to the compact design of the dovetail card slots 11 and buckles 12, it helps to save space, making the structure of the row of cards more compact. At the same time, this connection method can provide a neater appearance, and the simplified connection method helps to improve production efficiency and reduce assembly time; the dovetail-shaped card slots 11 and dovetail-shaped buckle 12 connection mechanisms at both ends of the row of cards provide a connection solution with stable structure, easy assembly, strong durability, space saving, beauty and improved production efficiency.

[0034] In this embodiment, the length of the connecting mechanism is the same as that of the reinforcing rib 7. This design can ensure the structural consistency between the connecting mechanism and the reinforcing rib 7. In this way, when the number of fixed cards 3 on one row of cards is insufficient, two or more rows of cards can be connected and used. The length of the connecting mechanism is the same as that of the reinforcing rib 7, and the distance between adjacent fixed cards 3 on the two connected rows of cards is the same as the distance between adjacent fixed cards 3 on the same row of cards, ensuring the consistency in appearance after the wire pipe is installed and helping to improve the overall beauty of the product.

[0035] On the lower surface of the bottom plate 1 below the reinforcing rib 7 of this embodiment, there is a dividing groove 8 perpendicular to the length direction of the bottom plate 1, and the cross-section of the dividing groove 8 is triangular. Since there are usually a large number of fixed cards 3 on the row of cards, when there are excess fixed cards 3 on the whole row of cards during the installation process, through the accurate positioning of the dividing groove 8, the row of cards can be easily divided into the actual required length, which helps to improve the efficiency of on-site construction.

[0036] Embodiment 2

[0037] On the side wall of the nail gun hole 6 in Embodiment 2, there is an annular anti-impact ring 14 (see Figure 7 ), the outer wall of the anti-impact ring 14 is in close contact with the side wall of the nail gun hole 6, and the anti-impact ring 14 is a stainless steel ring. During the use of the nail gun, the outer wall of the tubular anti-impact ring 14 is in close contact with the side wall of the nail gun hole 6 to reduce the impact on the structure of the row of cards when the nail gun fires, avoiding the rupture of the plastic row of cards due to the strong gas impact of the nail gun, greatly improving the anti-impact strength of the row of cards, reducing the probability of rupture of the row of cards, and improving the reliability of the row of cards.

[0038] The utility model designs a nail gun hole on the nail strip that is adapted to the muzzle of the nail gun, which can make the nail shooting port of the nail gun press on the nail strip. When using a nail gun for the ordinary steel nail hole of an ordinary nail strip, the nail shooting port cannot hold the nail strip, so the nail gun cannot be used. At the same time, the nail gun hole has a larger caliber than the ordinary steel nail hole in the prior art and can use more types of steel nails, so there are more types of steel nails to choose from. At the same time, the utility model retains the nail gun hole for using ordinary steel nails, and a nail gun device (pneumatic nail gun or electric nail gun) can be used to fix the nail strip on the ground or wall surface. Thus, with the nail strip of the utility model that can be used with both a nail gun and a nail gun, workers can use either a nail gun device or a nail gun device during use, without equipment limitations during use, greatly increasing flexibility and improving construction efficiency. In addition, the setting of the shock-proof ring can effectively absorb and disperse the impact force generated by the nail gun, reduce direct damage to the nail strip bottom plate and the card seat, and extend the service life of the nail strip.

[0039] Except for the above embodiments, within the scope disclosed in the claims and the specification of the present utility model, the technical features or technical data of the present utility model can be reselected and combined to form new embodiments, which can be achieved by those skilled in the art without creative labor. Therefore, these embodiments not detailedly described in the present utility model should also be regarded as specific embodiments of the present utility model and within the protection scope of the present utility model.
