Description

Technical Field

[0001] This utility model relates to the field of protective net installation technology, specifically to an easily detachable protective net fixing structure. Background Technology

[0002] Livestock fans used for ventilation and cooling generally have sealing structures of either butterfly valve type or louver type. For louver type sealing structures, they are usually installed on the inlet side of the fan. Self-balancing louvers open with airflow and close by gravity. To prevent chickens or plastic bags from being sucked into the fan and breaking the blades, protective netting is usually used to cover the outside of the louvers.

[0003] Because dust accumulation on the louver surface can affect the performance of the fan, as a routine maintenance operation, the protective mesh needs to be removed and the dust cleaned from the louvers every month. In the existing technology, the protective mesh is generally fixed to the louver frame by self-tapping screws, washers, and spacers. There are many fixing points, making the removal of the protective mesh cumbersome, and the fixing parts are easy to lose. At the same time, the protective mesh is large and heavy. When removing it, the protective mesh needs to be dragged, and then a power drill or screwdriver needs to be used to align with the fixing holes for removal. It is difficult for one person to operate, and usually requires two people to complete, which increases the workload. Utility Model Content

[0004] To address the shortcomings of existing technologies, a detachable protective net fixing structure is proposed, which solves the problems of cumbersome disassembly of the protective net and easy loss of fixing parts in the aforementioned background technologies.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A detachable protective net fixing structure includes a fixing component, which is mounted on a frame. The fixing component includes a snap-fit ​​part for snapping the protective net, and the protective net is detachably connected to the frame through the snap-fit ​​part.

[0007] Furthermore, the fixing component also includes a mounting plate, and a snap-fit ​​groove is formed between the snap-fit ​​part and the mounting plate to limit the movement of the protective net, so as to facilitate the fixed installation of the protective net.

[0008] Furthermore, the snap-fit ​​portion includes two snap-fit ​​pieces arranged opposite each other, the ends of the snap-fit ​​pieces are bent into guide plates, and a guide groove is formed between the two guide plates and communicates with the snap-fit ​​groove.

[0009] Furthermore, the snap-fit ​​portion includes a first snap-fit ​​plate and a second snap-fit ​​plate disposed opposite to each other, wherein the end of the first snap-fit ​​plate is located outside the end of the second snap-fit ​​plate to form a guide groove and thereby communicate with the guide groove.

[0010] Furthermore, the fixing components are provided in several groups, and the several groups of fixing components are evenly distributed along the circumference of the frame to provide stable support for the protective net.

[0011] Furthermore, the fixing component also includes a limiting part, which and the snap-fit ​​part are located on both sides of the mounting plate, respectively. The limiting part is inserted into the frame to realize the installation of the fixing component.

[0012] Furthermore, the limiting part is generally conical, and the limiting part includes at least two limiting blocks, which are spaced apart.

[0013] Furthermore, the limiting block is connected to the mounting plate via a connecting post, and the frame has mounting holes, the length of which matches the depth of the mounting holes.

[0014] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0015] This application uses a fixing component to facilitate the installation and removal of the protective net and the frame. The snap-fit ​​fixing structure replaces the self-tapping screws or bolts for compression fixing. The protective net can be removed without disassembling the fixing component, which is convenient for the removal of the protective net. At the same time, the protective net can be fixed by snap-fitting the snap-fit ​​part without the need for hole alignment. It can be easily operated by a single person. Attached Figure Description

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1:

[0028] like Figures 1 to 6 As shown, an easily detachable protective net fixing structure includes a fixing component 1, which is installed on a frame 2. The fixing component 1 includes a snap-fit ​​part for snapping the protective net 3, and the protective net 3 is detachably connected to the frame 2 through the snap-fit ​​part.

[0029] In this application, the installation and removal of the protective net 3 and the frame 2 are facilitated by setting the fixing component 1. The snap-fit ​​fixing structure replaces the self-tapping screw or bolt and other compression fixing. The protective net 3 can be removed without disassembling the fixing component, which is convenient for the removal of the protective net 3. At the same time, the protective net 3 can be fixed by the snap-fit ​​part without the need for hole installation. It can be easily operated by a single person.

[0030] In the easily detachable protective net fixing structure of this embodiment, the fixing component 1 further includes a mounting plate 4, and a snap-fit ​​groove is formed between the snap-fit ​​part and the mounting plate 4 to limit the positioning of the protective net 3, so as to realize the fixed installation of the protective net 3; the fixing component 1 also includes a limiting part, and the limiting part and the snap-fit ​​part are respectively located on both sides of the mounting plate 4, and the limiting part is inserted into the frame 2 to realize the installation of the fixing component 1.

[0031] The snap-fit ​​part and the limiting part are located on both sides of the mounting plate 4, and the fixing component 1 is integrally formed to form a snap-fit ​​structure, thereby avoiding the problem of frequent disassembly and easy loss of the fixing parts.

[0032] Specifically, the frame 2 has mounting holes 11. The fixing component 1 is clamped onto the perforated frame by the limiting part on one side of the mounting plate 4. The snap-fit ​​part on the other side of the mounting plate 4 faces outward. The guard net 3 can be clamped into the snap-fit ​​groove by pressing it from the outside, thus realizing the installation of the guard net 3. The guard net 3 can be easily removed from each snap-fit ​​part by gently lifting it again and pulling it outward. The operation is simple and easy to disassemble the guard net 3.

[0033] With the above setup, a single person can quickly install the protective netting 3, thereby reducing the initial wind turbine installation cost; similarly, a single person can quickly disassemble the protective netting 3, facilitating wind turbine maintenance.

[0034] In the easily detachable protective net fixing structure of this embodiment, the snap-fit ​​part includes two snap-fit ​​pieces 5 arranged opposite each other. The ends of the snap-fit ​​pieces 5 are bent into guide plates 6, and a guide groove is formed between the two guide plates 6 and the snap-fit ​​groove is connected.

[0035] Specifically, the snap-fit ​​piece 5 is fixedly connected to the outer surface of the mounting plate 4. The two snap-fit ​​pieces 5 gradually move towards the outside, and a snap-fit ​​groove is formed between the two snap-fit ​​pieces 5 to limit the single network cable of the protective net 3 that is snapped into the snap-fit ​​piece 5, thereby realizing the fixed installation of the protective net 3 on the frame 2.

[0036] The outer ends of the snap-fit ​​pieces 5 are bent in a direction away from each other to form two inclined guide plates 6, thereby forming a narrow guide groove between the two guide plates 6, which facilitates the entry of the net wire of the protective net 3 into the snap-fit ​​groove through the guide groove; preferably, the width of the guide groove is smaller than the diameter of the net wire of the protective net 3, and the snap-fit ​​pieces 5 are made of plastic material, which has sufficient strength and can deform, which facilitates the entry of the net wire into the guide groove and improves the limiting effect on the protective net 3.

[0037] In the easily detachable protective net fixing structure of this embodiment, the fixing component 1 is provided in several groups, and the several groups of fixing components 1 are evenly distributed along the circumference of the frame 2 to provide stable support for the protective net 3.

[0038] Specifically, the snap-fit ​​pieces 5 in several sets of fixing components 1 are respectively arranged vertically opposite each other, so that the guide groove is horizontal, and the horizontal mesh lines are snapped and limited from multiple positions along the circumference of the protective net 3 to prevent the protective net 3 from moving in the height direction; in the height direction of the frame 2, the distance between two adjacent fixing components 1 matches the distance between the horizontal mesh lines of the protective net 3, ensuring that the horizontally distributed mesh lines can smoothly cooperate with the snap-fit ​​parts in each set of fixing components 1.

[0039] Preferably, the snap-fit ​​piece 5 can also be symmetrically distributed left and right along the vertical direction, and the vertical guide groove cooperates with the vertical mesh line of the protective net 3, while resisting the horizontal mesh line to limit the position of the protective net 3.

[0040] In the easily detachable protective net fixing structure of this embodiment, the limiting part is generally conical, and the limiting part includes at least two limiting blocks 9, which are spaced apart.

[0041] Specifically, there are four limit blocks 9, which are arranged in a circular array. During the process of inserting the limit blocks 9 into the mounting holes 11 on the frame 2, the conical shape allows the limit blocks 9 to be assembled more smoothly. The limit blocks 9 deform and move closer to each other. After assembly, they spring back to a free state to prevent them from coming out of the mounting holes 11, thus achieving the purpose of fixing the component 1 on the frame 2.

[0042] Preferably, the limiting part can also be set as two limiting blocks 9 distributed opposite to each other on the back of the mounting plate 4, so as to ensure the limiting effect while reducing the processing difficulty.

[0043] In the easily detachable protective net fixing structure of this embodiment, the limiting block 9 is connected to the mounting plate 4 through the connecting post 10, and the length of the connecting post 10 matches the depth of the mounting hole 11.

[0044] Specifically, the outer surface shape of the connecting post 10 matches the curvature of the inner surface of the mounting hole 11. After the limiting block 9 passes through the mounting hole 11, the shape of the connecting post 10 matches that of the mounting hole 11, preventing the mounting plate 4 and the snap-fit ​​part from moving radially along the mounting hole 11, thus improving the fixing stability and facilitating the determination of the up-down or left-right position of the snap-fit ​​piece 5. This prevents the mounting plate 4 from moving arbitrarily and causing the guide groove to change its horizontal state, which would affect the quick disassembly and installation of the guard net 3. At the same time, the boss plane of the limiting block 9 contacts the back plane of the frame 2 to prevent it from coming off. The length of the connecting post 10 matches the hole depth, preventing the mounting plate 4 from moving axially in the mounting hole 11 and improving the limiting effect on the snap-fit ​​part and the guard net 3.

[0045] Example 2:

[0046] In the easily detachable protective net fixing structure of this embodiment, such as Figure 7 and Figure 8 As shown, the basic technical features of Embodiment 1 are adopted, except that: the snap-fit ​​part includes a first snap-fit ​​plate 7 and a second snap-fit ​​plate 8 disposed opposite to each other, and the end of the first snap-fit ​​plate 7 is located outside the end of the second snap-fit ​​plate 8 to form a guide groove and thus connect to the guide groove.

[0047] Specifically, the first snap-fit ​​plate 7 and the second snap-fit ​​plate 8 are L-shaped. The first snap-fit ​​plate 7 is fixedly connected to the upper edge of the mounting plate 4, with its opening facing downwards. The second snap-fit ​​plate 8 is fixedly connected to the lower edge of the mounting plate 4, with its opening facing upwards. The first snap-fit ​​plate 7 covers the outside of the second snap-fit ​​plate 8, thereby sealing the opening of the second snap-fit ​​plate 8. When installing the protective net 3, the network cable moves upwards along the guide groove between the opening of the first snap-fit ​​plate 7 and the second snap-fit ​​plate 8 to enter the snap-fit ​​groove. When disassembling, the protective net 3 moves in the opposite direction to allow the network cable to come out of the snap-fit ​​groove.
