Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic product processing, in particular to a plastic grid edge sealing structure. Background Art
[0002] Plastic grilles have many uses and are very common in various fields. In air filtration equipment, the air inlet or outlet needs to filter out debris and allow air to pass through fully, so a plastic grille will be installed at the air inlet. Its advantages are low cost, simple installation, and convenient maintenance and replacement. The installation of plastic grilles is generally to assemble multiple small plastic grille pieces into a complete large grille surface. However, when assembling multiple plastic grilles, other means are needed to make the plastic grilles fit tightly together and seal the gaps generated after the assembly. Generally, plastic welding rods are used to seal the outer edges of the assembled plastic grilles to make them tightly connected. In the existing technology, since there is no position on the outer edge of the plastic grille that can be used for sealing, and there is a lack of space for plastic welding rods to seal, plastic welding rods are generally directly coated on the top of the outer edges of the two plastic grilles. This method makes the connection between the two plastic grilles very loose, and the plastic welding rods are very easy to fall off due to vibration. Utility Model Content
[0003] In view of the defects of the above-mentioned existing technologies, the technical problem to be solved by the present invention is: to provide a space designed to accommodate the edge sealing of plastic welding rods, to fill the gaps generated after the grille components are assembled, so that multiple grille components can be tightly connected after assembly, and the plastic welding rods are not easy to fall off.
[0004] In order to achieve the above object, the present invention provides the following solutions:
[0005] A plastic grille edge sealing structure includes a grille component. A pit is provided around the grille component to accommodate plastic welding rods for edge sealing when assembled with other grille components. An anti-falling protrusion is provided in the pit to prevent the plastic welding rods from falling out.
[0006] Furthermore, the grille component in the present invention is quadrilateral, and the pits are arranged at the top of the four edges of the grille component.
[0007] Furthermore, the cross section of the pit in the present invention is L-shaped.
[0008] Furthermore, when the grid assembly of the present invention is assembled from the side, every two pits and grooves form a groove with a concave cross-section for edge sealing with plastic welding rods.
[0009] Furthermore, the anti-slip protrusions in the present invention are a plurality of protrusions arranged in the pit and on the upright side wall surface.
[0010] Furthermore, each of the protruding columns in the present invention is evenly spaced.
[0011] Furthermore, the pits and bosses in the present invention are integrally formed using a CNC cutting process.
[0012] In summary, the present invention has the following beneficial effects compared to the prior art:
[0013] The utility model provides grooves so that when the grille components are assembled, grooves that can be used for edge sealing with plastic welding rods can be left, thereby filling the gaps between the grille components and making the grille components tightly connected. In addition, the anti-slip protrusions can prevent the plastic welding rods from slipping off after the edge sealing with plastic welding rods is dried and hardened, thereby assembling a complete and firm large grille surface.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0019] like Figures 1 to 4 The embodiment of the present invention preferably provides a plastic grille edge sealing structure, comprising a grille assembly 1 having grooves 2 formed around the perimeter of the grille assembly 1 to accommodate plastic welding rods for edge sealing when joined with other grille assemblies 1. Within the grooves 2 are anti-dropout protrusions 3 to prevent the plastic welding rods from falling out. The grille assembly is plate-shaped, with multiple lines interlaced in the middle to form a regular mesh, allowing air to pass through the various holes within this mesh. Multiple grille assemblies can be assembled into a larger grille assembly, and the specific shape can be cut to fit into the air intake of the equipment. The connection points between the grille assemblies are spaced apart. In this technical solution, grooves are provided around the perimeter of the grille assembly, allowing users to fill the grooves with plastic welding rods to fill the gaps and allow the grille assemblies to connect and assemble. The anti-dropout protrusions are designed to address the problem of plastic welding rods easily falling out after hardening. By adding the anti-dropout protrusions, the hardened plastic welding rods are locked into place by the anti-dropout protrusions, thereby securely retaining them in the grooves.
[0020] The grille assembly 1 of this invention is quadrilateral, with the grooves 2 positioned at the tops of the four edges of the grille assembly 1. The quadrilateral grille assembly in this technical solution is a conventional shape in the prior art, with the grooves positioned at the tops of the four edges, facilitating edge sealing after multiple grille assemblies are assembled. Depending on the actual situation, if a custom-shaped grille assembly is used, grooves can simply be provided at each outer edge of the custom-shaped grille assembly to achieve the same edge sealing effect.
[0021] The cross section of the pit 2 in the present invention is L-shaped. The L-shaped pit can be easily sealed with a plastic welding rod, and being set at an L-shaped right angle is more convenient for numerical control processing.
[0022] When multiple grille components 1 are assembled from the side, each pair of recesses 2 forms a concave groove for plastic welding rod edge sealing. The recesses of each grille component have the same depth, so when two L-shaped recesses are assembled, they form a concave groove that can accommodate plastic welding rod edge sealing.
[0023] The anti-dropout protrusions 3 of the present invention are a plurality of protrusions disposed on the upright sidewalls of the groove 2. The protrusions extend laterally from the sidewalls of the groove. When the plastic welding rod is filled into the groove, the soft plastic welding rod can wrap around the protrusions. When the plastic welding rod hardens, the protrusions will lock the hardened plastic welding rod, preventing it from falling out either upward or downward.
[0024] In the utility model, each of the protrusions is evenly spaced, which helps to prevent plastic welding rods at all positions from falling out during edge sealing.
[0025] The groove 2 and the protrusion in the present invention are integrally formed using a CNC cutting process, which allows the plastic grille components to be mass-produced, with a simple structure and low cost.
[0026] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
