Detailed Description

The present utility model will be further described with reference to the following specific embodiments, and it should be noted that, on the premise of no conflict, new embodiments may be formed by any combination of the embodiments or technical features described below.

In the description of the present utility model, it should be noted that, for the azimuth words such as terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the azimuth and positional relationships are based on the azimuth or positional relationships shown in the drawings, it is merely for convenience of describing the present utility model and simplifying the description, and it is not to be construed as limiting the specific scope of protection of the present utility model that the device or element referred to must have a specific azimuth configuration and operation.

It should be noted that the terms "first," "second," and the like in the description and in the claims are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

The terms "comprises" and "comprising," along with any variations thereof, in the description and claims, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Further studying the technical problems of inconvenient installation, high manufacturing cost, high installation cost, and large installation gap of the existing fence system, the inventor found that the key to the problems is to use a net frame fixing ring 100, the existing net frame fixing ring 100 having a clamping jaw 101 thereon and having a net frame fixing nut 102, the net frame fixing ring 100 being fixed on a post 1 by the net frame fixing nut 102 and limiting displacement of the fence 2 by the clamping jaw 101, the specific analysis is as follows:

(1) Although the purse net 2 and the upright 1 can be well fixed by using the net frame fixing ring 100 to prevent the purse net 2 from falling from the upright 1, the net frame fixing ring 100 is complex to process, the clamping jaw 101 arranged on the periphery of the net frame fixing ring is generally formed by punching, and in addition, a fixing hole is required to be formed and tapped, so that bolts (namely the net frame fixing nuts 102) are convenient to fix the purse net 2 and the upright 1, and therefore, the processing cost of the net frame fixing ring 100 is relatively high;

(2) Installing a traditional purse net 2 usually requires two persons to complete the installation together, firstly, sleeving a lower-side net frame fixing ring 100 on a column 1, then fixing the lower side of the purse net 2 by using clamping jaws 101, subsequently sleeving an upper-side net frame fixing ring 100 on the column 1, fixing the upper side of the purse net 2 by using clamping jaws 101 of the upper-side net frame fixing ring 100, and finally, lifting the purse net 2 by one worker and respectively fixing each net frame fixing ring 100 and the column 1 by the other worker, thereby increasing the installation cost, and the installation cost of the net frame fixing ring 100 is usually 25 yuan/meter. In addition, it should be noted that expanding the installation fence by using the frame fixing ring 100 is very inconvenient, because the clamping jaw 101 of the frame fixing ring 100 is arranged at the periphery of the frame fixing ring 100 and is limited by the structures of the clamping jaw 101 and the frame 21, the frame fixing ring 100 can only be installed at the top and the bottom of the purse net 2, and the two upper and lower frame fixing rings 100 are oppositely arranged, that is, the clamping jaw 101 of the frame fixing ring 100 at the top faces downwards as shown in fig. 2 and 3, the clamping jaw 101 of the frame fixing ring 100 at the bottom faces upwards, so that the frame 21 of the purse net 2 is clamped, the falling off of the frame 21 is avoided, and after the fixation of the purse net 2 between the oppositely arranged upright posts 1 is completed, the outer net outside the upright posts 1 is also required to be expanded and installed, and the connection between the frame fixing ring 100 and the upright posts 1 is required to be dismantled, so that the expansion installation is convenient, and the operation is very inconvenient and time-consuming.

(3) The clamping jaw 101 of the screen frame fixing ring 100 is used for fixing the purse net 2, the screen frame 21 of the purse net 2 is made of square tubes, the surface and the inner wall are not machined any more, so that the dimensional accuracy of the wall thickness is not accurate, the distance between the clamping jaw 101 and the screen frame fixing ring 100 is generally larger than the wall thickness (in this specific embodiment, a gap L exists between the screen frame 21 and the clamping jaw 101 after the installation is finished), so that the screen frame 21 is conveniently fixed, after the installation, the gap exists between the screen frame 21 and the inner wall of the clamping jaw 101, large shaking easily occurs, the installation gap is large, and the problem of the installation gap is caused, and due to the structure of the clamping jaw 101, the screen frame fixing ring 100 can only be installed at the top and the bottom of the purse net 2, if the installation stability of the purse net 2 is required to be increased, the clamping jaw 101 and the screen frame 21 cannot be fixed is also fixed, so that the installation gap is large, the stability is poor, and the problem of poor installation quality is caused.

Based on this, the inventor developed a fence system, one embodiment of which is shown in fig. 4a to 12, the fence system comprises a plurality of groups of fences, the fences comprise upright posts 1 and a purse net 2, the upright posts 1 are oppositely arranged, and mounting holes 11 are formed on the side surfaces of two adjacent upright posts 1 which are oppositely arranged; the left and right sides of purse seine 2 all outwards bulge and are provided with spliced pole 3, and the quantity of unilateral spliced pole 3 is not less than two to arrange along upper and lower direction, mounting hole 11 and spliced pole 3 mutually mate, and homonymy spliced pole 3 is suitable for along the invasion mounting hole 11 in the left and right directions, until the medial surface of purse seine 2 contradicts the medial surface of stand 1, spliced pole 3 is suitable for simultaneously bearing because the moment that the gravity of purse seine 2 caused, and detachably connects purse seine 2 and stand 1. As shown in fig. 4a, three posts 1 form a fence system and are very malleable, i.e. can continue to extend outwards. As shown in fig. 4b, two posts 1 form a fence, which can also play a protective role. In this particular embodiment, the uprights 1 are adapted to be aligned in a right-left or front-rear direction and to be disposed opposite each other, so that they can constitute a completed fence for protection.

It should be noted that the connection post 3 may be detachably connected to the seine 2, or may be non-detachably connected, such as by welding. The single-sided connection columns 3 are arranged in the vertical direction, and not only vertically but also diagonally. The mounting holes 11 are matched with the connecting columns 3, and the positions, the numbers and the shapes of the mounting holes are mutually corresponding, so that the connecting columns 3 can be mounted in the corresponding mounting holes 11, and the purse seine 2 and the upright columns 1 can be detachably connected.

Since the seine 2, in particular the seine 2 having a long length, is composed of iron, the weight is large, and both stability and durability are considered when connecting the seine 2 and the pillar 1. The inventors have accordingly developed a fencing system and have developed an assembly method comprising the steps of: as shown in figure 5 of the drawings,

s100, mounting the first upright 13 on the ground;

s200, at least two connecting columns 3 which are arranged on the same side of the purse net 2 along the up-down direction invade into the mounting holes 11 of the upright posts 1 along the left-right direction, the connecting columns 3 bear the torque caused by the gravity of the purse net 2 at the same time, the outer side surface of the purse net 2 is perpendicular to the horizontal plane, and the outer side surface of the purse net 2 is abutted against the inner side surface of the upright posts 1;

s300, installing second upright posts 14 which are oppositely arranged on at least two connecting posts 3 which are arranged on the other side of the purse net 2 along the left-right direction along the up-down direction;

s400. mounting the second upright 14 disposed opposite to the ground.

As shown in fig. 5, the connecting columns 3 protruding outwards from the left and right sides of the purse net 2 are provided, and the number of the connecting columns 3 on one side is not less than two, so that the torque caused by the gravity of the purse net 2 can be well fixed, and the problem that the connecting columns 3 are broken due to the overweight purse net 2 can be prevented. The processing cost of the connecting column 3 is lower, the screen frame fixing ring 100 is omitted, in the actual production process, the mounting holes 11 are only required to be formed in the upright columns 1, and the connecting column 3 is arranged on the side edge of the screen frame 21, so that the manufacturing cost is greatly reduced;

in the actual use process, at least two connecting columns 3 which are arranged on the same side of the purse net 2 along the up-down direction can invade the mounting holes 11 of the upright posts 1 along the left-right direction, the connecting columns 3 bear the torque caused by the gravity of the purse net 2 at the same time, and the side surfaces on the left side and the right side of the purse net 2 are perpendicular to the horizontal plane, so that the connecting columns 3 can bear the torque generated by the larger gravity of the purse net 2, the longer purse net 2 is convenient to mount, the mounting cost is lower, and the rail system can be assembled by only one worker, thereby greatly reducing the assembly cost and improving the production efficiency; and because the structure is simple and convenient, the small installation clearance is easy to keep, and the integral assembly precision is further improved.

Further described, the beneficial effects of the structure are: as shown in fig. 9, when the seine 2 is installed in the installation hole 11 through the connection post 3, since the outer side surface of the seine 2 (i.e. the net frame 21) is controlled to abut against the inner side surface of the column 1, since the seine 2 and the column 1 will also generate contact and force, the stress mode is changed, most of the torque generated by the gravity of the seine 2 is borne by the moment generated by the force between the seine 2 and the column 1, only a small part of the torque generated by the gravity of the seine 2 is borne by the connection post 3, the load bearing capacity of the connection post 3 is greatly increased, and compared with the conventional pin shaft connection method (i.e. the installation method in which the outer side surface of the seine 2 does not abut against the inner side surface of the column 1), the connection post 3 bears the torque generated by the gravity of all the seine 2 when the seine 2 is stressed on one side (i.e. in the S200 installation step), so that the impact load received by the connection post 3 is too large, and the connection post 3 is very liable to break, thereby forming an installation failure result, and the instant load may cause deformation of the connection post 3, resulting in poor subsequent installation effect.

In addition, two connecting columns 3 are arranged along the vertical direction, so that the situation that the purse seine 2 rotates around a single connecting column 3 in the installation process can be avoided, the bearing capacity of the connecting column 3 can be further increased, and the contact area between the outer side surface of the purse seine 2 and the inner side surface of the upright column 1 is further ensured, so that the bearing capacity of the connecting column 3 is further improved, and the installation stability is more superior.

By using the above assembly method, a worker can complete the assembly of the fence system, namely, the first upright post 13 is fixed firstly, the purse net 2 is installed on the upright post 1 through the connecting post 3, then the second upright post 14 is installed on the purse net 2 through the connecting post 3 on the other side, and finally the second upright post 14 is fixed, so that the single person can be installed, the assembly cost can be reduced to 5 yuan/meter, and the assembly cost is greatly reduced. Of course, it is easy to understand that the fence system adopting the structure does not need to use the net frame fixing ring 100, does not need additional procedures such as tapping, punching and the like, greatly reduces the processing cost, and has great effect on improving the market competitiveness of the product.

Further preferably, as shown in fig. 6, 7, 8a and 8b, the purse net 2 comprises a net frame 21 and a net sheet 22, the net sheet 22 is suitable for being mounted on the net frame 21, the left and right sides of the net frame 21 are provided with connecting columns 3 protruding outwards, the connecting columns 3 are detachably connected with the net frame 21, the mounting holes 11 comprise an upper hole 111 and a lower hole 112, the upper hole 111 and the lower hole 112 are arranged along the up-down direction and are communicated with each other, the inner diameter of the upper hole 111 is larger than the inner diameter of the lower hole 112, the outer diameter of the connecting columns 3 is smaller than or equal to the inner diameter of the lower hole 112, and the connecting columns 3 are suitable for being invaded into the upper hole 111 along the left-right direction and finally enter the lower hole 112. It should be noted that the mounting hole 11 need not be circular, but may be square, and the shape of the connecting post 3 is matched with that of the mounting hole, i.e. in this embodiment, a circular hole is shown in fig. 8a, and a square hole is shown in fig. 8 b.

The connection column 3 and the net frame 21 are detachably connected, so that the fence is more convenient to manufacture, and compared with the method of fixing the connection column 3 and the net frame 21 by using welding, the detachable connection method can fix the connection column 3 and the net frame 21 by only arranging the connection column mounting holes 211 for mounting the connection column 3 on the net frame 21, and independently producing the net frame 21 and the connection column 3 has higher production efficiency and lower production cost. The communicating ground holes 111 and the lower holes 112 are formed to facilitate the use in the assembly process, since the aperture of the upper holes 111 is larger than the size of the connecting columns 3, the connecting columns 3 can relatively easily enter the upper holes 111, and since the upper holes 111 and the lower holes 112 are arranged along the up-down direction, the connecting columns 3 can enter the lower holes 112 from the upper holes 111 under the action of gravity and relatively lock the positions of the connecting columns 3 in the lower holes 112, thereby playing a role of fixing the downward displacement distance of the connecting columns 3 in the vertical direction, and the displacement of the purse net 2 in the left-right direction can enable the outer side surface of the net frame 21 (i.e. the left side surface of the net frame 21 in fig. 6) to abut against the inner side surface of the upright column 1 (i.e. the right side surface of the upright column 1 in fig. 6), so as to limit the displacement of the purse net 2 in the left-right direction, and the torque received by the connecting columns 3 is relatively small by virtue of the arrangement, so that the stability and durability of the fence are improved.

Further preferably, the upright 1 is made of square tube, the inner wall of the upright 1 defines a mounting cavity 12 arranged along the vertical direction, and the mounting hole 11 is adapted to communicate with the mounting cavity 12; the pen also includes a top overcap adapted to fit over the top of the square tube and enclose the mounting cavity 12. The Kong Men cap and top closure are provided to close the mounting cavity 12 and to promote the integrity of the outer surface of the stud 1.

Further preferably, as shown in fig. 7, the mesh sheet 22 is mounted on the front side of the mesh frame 21, and the connection posts 3 are provided on the frame of the mesh frame 21. The mesh 22 is arranged on the front side surface of the net frame 21, so that the mesh 22 and the net frame 21 can be conveniently fixed through welding, the connecting column 3 is arranged on the frame of the net frame 21, the connection strength of the connecting column 3 and the net frame 21 can be improved, and the integrity of the fence is further improved.

Further preferably, as shown in fig. 8a, both the upper hole 111 and the lower hole 112 are circular holes; the mounting hole 11 further includes a connection hole 113, the connection hole 113 being adapted to communicate the upper hole 111 and the lower hole 112, the connection hole 113 having an inner diameter identical to an inner diameter of the lower hole 112.

The upper hole 111 and the lower hole 112 are round holes, so that the connecting column 3 can more conveniently invade the mounting hole 11 along the left-right direction, friction force generated when the mounting hole 11 (comprising the upper hole 111 and the lower hole 112) is contacted with the surface of the connecting column 3 is reduced, the connecting hole 113 plays a guiding role, besides better guiding the connecting column 3 to enter the lower hole 112, displacement, generated by the purse net 2, along the front-back direction can be limited to a certain extent in the process of entering the lower hole 112, the connecting column 3 can enter the lower hole 112 more conveniently, and the phenomenon of clamping can not occur.

Further preferably, as shown in fig. 10, the upright 1 is made of square tube, the inner wall of the upright 1 defines a mounting cavity 12 arranged along the vertical direction, and the mounting hole 11 is adapted to communicate with the mounting cavity 12; the connecting column 3 is sleeved with a limit sleeve 31, the limit sleeve 31 comprises a protection ring 312 and a limit ring 311, the protection ring 312 is arranged along the axial direction of the connecting column 3, the outside of the protection ring 312 is connected with the limit ring 311, the limit ring 311 and the protection ring 312 are sleeved on the connecting column 3, the outer diameter of the limit ring 311 is smaller than or equal to the inner diameter of the upper hole 111, and the outer diameter of the limit ring 311 is larger than the inner diameter of the lower hole 112; when the connecting column 3 is installed, the stop collar 31 is located at the outer side of the net frame 21, the stop collar 311 is suitable for penetrating into the installation cavity 12 and limiting the displacement of the purse net 2, and the circumference of the protection ring 312 is suitable for abutting against the inner wall of the installation hole 11 and limiting the stress of the connecting column 3.

The limiting sleeve 31 is arranged, so that the connecting column 3 and the purse net 2 can be conveniently and detachably installed, and the displacement of the purse net 2 along the left-right direction is controlled through the limiting effect of the limiting sleeve 31. In this particular embodiment, as shown in fig. 10, the retainer 31 enters the mounting cavity 12 through the upper hole 111 and finally enters the lower hole 112 through the connection hole 113, and since the outer diameter of the retainer ring 311 is larger than the inner diameter of the lower hole 112 and the outer diameter of the protection ring 312 is smaller than or equal to the inner diameter of the lower hole 112, the protection ring 312 can pass through the lower hole 112, and the retainer ring 311 cannot pass through the lower hole 112, and thus the displacement of the seine 2 in the left-right direction is controlled by controlling the displacement of the retainer ring 311. In this embodiment, the right side surface of the limiting ring 311 abuts against the inner wall of the mounting cavity 12, and the left side surface of the net frame 21 abuts against the right side surface of the upright post 1, so that the load on the connecting post 3 caused by the gravity of the purse net 2 is further reduced, and the service life of the connecting post 3 is prolonged.
