Technical Field

[0001] The present invention relates to the technical field of grille installation, and more specifically, to a grille installation structure. Background Art

[0002] Before a sewage treatment system or a water pump, a grille must be set up. The grille is the most important auxiliary equipment in a sewage pumping station. Generally, a grille consists of a group of parallel bars, which are obliquely placed at the inlet of the sump of the pumping station; the quantity of suspended solids and floating objects that the grille can intercept varies greatly depending on the width of the gaps between the selected bars and the nature of the sewage. The grille is an important facility in the physical treatment of sewage.

[0003] After the grille has been used for a long time, it is necessary to clean the grille regularly or replace it after it is damaged. However, at present, the installation between grilles is carried out through welding or the cooperation of installation clip bolts. The subsequent welding cannot be disassembled, and the cleaning is difficult; the installation with installation clips has a large workload, the operation is cumbersome, and both the installation and disassembly take a lot of time and manpower, resulting in low work efficiency and poor use effect.

[0004] Therefore, it is necessary to provide a grille installation structure to solve the above technical problems. Summary of the Invention

[0016] As a further solution of the present invention: a blocking strip is arranged on the lower baffle for restricting the horizontal movement of the positioning bottom plate.

[0017] As a further solution of the present invention: a fixing hole is opened on the L-shaped limiting rod, and the fixing mechanism includes:

[0018] A sunken groove is opened in the second mounting plate, and a trapezoidal insertion block matched with the fixing hole is slidably arranged on the inner wall of the sunken groove;

[0019] A second elastic member, one end of which is connected to the inner wall of the sunken groove and the other end is connected to the trapezoidal insertion block;

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0039] Please refer to Figure 1-6 , a grille installation structure, including a grille plate 1, and further including: a first mounting plate 2 and a second mounting plate 3, both having two and arranged on the outer walls around the grille plate 1; two sets of limiting rods, rotatably arranged at both ends of the first mounting plate 2, each set of limiting rods including two L-shaped limiting rods 4, respectively located on both sides of the first mounting plate 2; two positioning mechanisms 6, respectively arranged at the positions of the corresponding L-shaped limiting rods 4 on the first mounting plate 2, for positioning the installation position of the second mounting plate 3; two fixing mechanisms 7, arranged on the second mounting plate 3, and fixing the first mounting plate 2 and the second mounting plate 3 to each other through cooperation with the L-shaped limiting rods 4. Two rotating rods 5 are rotatably arranged on the first mounting plate 2 through bearings, and two L-shaped limiting rods 4 are arranged on each rotating rod 5, respectively located at both ends of the rotating rod 5.

[0040] When installing or disassembling the grille, first place a grille plate 1 to be installed on one side of another grille plate 1, so that the first mounting plate 2 on one grille plate 1 corresponds to the second mounting plate 3 on another grille plate 1, that is, make the second mounting plate 3 contact the first mounting plate 2. First, place the second mounting plate 3 on one grille plate 1 between the two L-shaped limiting rods 4 of the first mounting plate 2 on another grille plate 1, and through the positioning mechanism 6, make the adjacent grille plate 1 aligned with this grille plate 1 vertically and horizontally. That is, through the positioning mechanism 6 and the L-shaped limiting rods 4, the adjacent grille plates 1 to be installed can be positioned, which can avoid the situation of manually repeatedly moving the grille plate 1 to align the two grille plates 1, enabling the grille plate 1 to be accurately and quickly aligned for subsequent installation, saving time and effort, being convenient to operate, and having high installation efficiency.

[0041] By operating the positioning mechanism 6 to release the restriction on the L-shaped limiting rod 4, at this time, the L-shaped limiting rod 4 can rotate along the rotating rod 5, and the L-shaped limiting rod 4 moves towards the direction of the second mounting plate 3. The rotation of the L-shaped limiting rod 4 drives the positioning bottom plate 8 together. When the positioning bottom plate 8 touches the second mounting plate 3, the positioning bottom plate 8 will flip along the hinge point with the L-shaped limiting rod 4, as Figure 6As shown. The L-shaped limiting rod 4 can be restricted and fixed by the fixing mechanism 7. At this time, the first mounting plate 2 and the second mounting plate 3 can be fixed together, that is, the two adjacent grille plates 1 can be fixed to each other, and multiple grille plates 1 can be installed in this way. Similarly, when the grille plate 1 is disassembled, the fixing mechanism 7 on the L-shaped limiting rod 4 can be released, so that the L-shaped limiting rod 4 is rotated from the horizontal direction to the vertical direction. At this time, the second mounting plate 3 and the first mounting plate 2 can be disengaged, that is, the adjacent grille plates 1 can be separated, and the disassembly process is completed. Therefore, it can be seen from the above that the installation and disassembly of the grille plate 1 are very simple and convenient, avoiding the current situation of cumbersome welding and inability to disassemble. At the same time, the workload of this solution is small during installation and disassembly, and the operation is simple, which saves a lot of manpower and time, greatly improves work efficiency, has good use effect, and is highly practical.

[0042] In this embodiment, preferably, please refer to Figure 2 、 Figure 4 and Figure 9 The bottom of the L-shaped limiting rod 4 is hinged with a positioning base plate 8. The positioning mechanism 6 includes: a movable groove 61, which is opened in the first mounting plate 2; a lower baffle 62, which is movably inserted in the movable groove 61. A first elastic member 63 is provided between the lower baffle 62 and the inner wall of the movable groove 61. The first elastic member 63 in this application is a spring. Due to the restriction of the positioning base plate 8 by the lower baffle 62, the positioning base plate 8 can be prevented from flipping over. At the same time, the rotation of the L-shaped limiting rod 4 can also be restricted. At this time, the L-shaped limiting rod 4 and the positioning base plate 8 will be stable in this position. When the second mounting plate 3 is placed, the lower baffle 62 can be driven to move in the direction away from the L-shaped limiting rod 4. The lower baffle 62 will slide along the movable groove 61 and stretch the first elastic member 63. When the lower baffle 62 is away from the L-shaped limiting rod 4 by a certain distance, the lower baffle 62 no longer restricts the L-shaped limiting rod 4. At this time, the L-shaped limiting rod 4 can be rotated along the rotating rod 5.

[0043] A baffle 9 is provided on the lower baffle 62 for limiting the horizontal movement of the positioning base plate 8. The restriction of the positioning base plate 8 by the baffle 9 can further prevent the rotation of the L-shaped limiting rod 4, thereby improving the positioning effect of the positioning base plate 8 on the second mounting plate 3 and the grille plate 1.

[0044] In this embodiment, preferably, please refer to Figure 3 and Figure 7-8, a fixing hole 10 is formed in the L-shaped limiting rod 4. The fixing mechanism 7 includes: a sunken groove 71 formed in the second mounting plate 3, and a trapezoidal insertion block 72 slidably disposed on the inner wall of the sunken groove 71 and adapted to the fixing hole 10; a second elastic member 73, one end of which is connected to the inner wall of the sunken groove 71 and the other end of which is connected to the trapezoidal insertion block 72. The second elastic member 73 in this application is a spring; a limiting component 74 disposed in the trapezoidal insertion block 72 for restricting the up and down movement of the trapezoidal insertion block 72. When the L-shaped limiting rod 4 rotates, it gradually contacts the trapezoidal insertion block 72 and exerts a pressure on the trapezoidal insertion block 72. The trapezoidal insertion block 72 is pressed to move along the inside of the second mounting plate 3, that is, in the sunken groove 71, and compresses the second elastic member 73. The L-shaped limiting rod 4 continues to move. When the L-shaped limiting rod 4 rotates to the corresponding position of the fixing hole 10 and the trapezoidal insertion block 72, the trapezoidal insertion block 72 is no longer pressed. The resilience of the second elastic member 73 drives the trapezoidal insertion block 72 to move outwards, and the trapezoidal insertion block 72 enters the fixing hole 10. After the trapezoidal insertion block 72 returns to the initial position, the L-shaped limiting rod 4 can be restricted at this time through the limiting component 74. As Figure 6-7 shown, the L-shaped limiting rod 4 can be restricted and fixed by the action of the limiting component 74 and the trapezoidal insertion block 72.

[0045] In this embodiment, preferably, please refer to Figure 7-8 , the limiting component 74 includes an inner groove 741, a limiting block 742 and a third elastic member 743. The third elastic member 743 in this application is a spring. The inner groove 741 is formed in the trapezoidal insertion block 72. The limiting block 742 is slidably disposed in the inner groove 741. Two ends of the third elastic member 743 are respectively connected to the limiting block 742 and the inner wall of the inner groove 741; a fitting groove 11 adapted to the limiting block 742 is formed in the second mounting plate 3. When the trapezoidal insertion block 72 enters the sunken groove 71, the limiting block 742 enters the fitting groove 11; when the trapezoidal insertion block 72 gradually enters the fixing hole 10, the inner wall of the fixing hole 10 presses the limiting block 742, causing the limiting block 742 to enter the inner groove 741 and compressing the third elastic member 743. When the trapezoidal insertion block 72 returns to the initial position, the limiting block 742 is not pressed by the inner wall of the fixing hole 10 at this time. The resilience of the third elastic member 743 drives the limiting block 742 to pop out of the inner groove 741. At this time, the L-shaped limiting rod 4 is restricted and fixed by the action of the limiting block 742 and the trapezoidal insertion block 72.

[0046] In this embodiment, preferably, please refer to Figure 7, on both sides of the fixing hole 10 on the L-shaped limiting rod 4, two stoppers 12 are provided, and the distance between the two stoppers 12 is greater than or equal to the width of the limiting block 742. By providing the two stoppers 12, the limiting block 742 can be further restricted, and the situation of the limiting block 742 moving can be greatly avoided, further ensuring the stability of the installation of the grille plate 1 and having a good use effect.

[0047] Working principle: When installing or disassembling the grille, first place a grille plate 1 to be installed on one side of another grille plate 1, so that the first mounting plate 2 on one grille plate 1 corresponds to the second mounting plate 3 on another grille plate 1, that is, make the second mounting plate 3 contact the first mounting plate 2. First, place the second mounting plate 3 on one grille plate 1 between the two L-shaped limiting rods 4 on the first mounting plate 2 of another grille plate 1, and make both ends of the second mounting plate 3 rest on the positioning bottom plate 8 on the L-shaped limiting rod 4. Due to the restriction of the lower baffle 62 on the positioning bottom plate 8, at this time, the flipping of the positioning bottom plate 8 can be avoided, and at the same time, the rotation of the L-shaped limiting rod 4 can also be restricted. At this time, the L-shaped limiting rod 4 and the positioning bottom plate 8 will be stable here. When the second mounting plate 3 on the adjacent grille plate 1 is placed between the two L-shaped limiting rods 4 on this first mounting plate 2, and at this time, the adjacent grille plate 1 and this grille plate 1 are aligned up and down and front and back, thus the positioning bottom plate 8 and the L-shaped limiting rod 4 can play a positioning role for the adjacent grille plate 1 to be installed.

[0048] After the second mounting plate 3 is placed, first drive the lower baffle 62 to move away from the L-shaped limiting rod 4. The lower baffle 62 will slide along the moving slot 61 and stretch the first elastic member 63. When the lower baffle 62 is a certain distance away from the L-shaped limiting rod 4, at this time, the lower baffle 62 no longer restricts the L-shaped limiting rod 4. At this time, the L-shaped limiting rod 4 can rotate along the rotating rod 5 and move towards the second mounting plate 3. The rotation of the L-shaped limiting rod 4 drives the positioning bottom plate 8 together. When the positioning bottom plate 8 contacts the second mounting plate 3, the positioning bottom plate 8 will flip along the hinge point with the L-shaped limiting rod 4, as Figure 6As shown in the figure. When the L-shaped limiting rod 4 rotates, it gradually comes into contact with the trapezoidal insert block 72 and exerts pressure on the trapezoidal insert block 72. The trapezoidal insert block 72 will be pressed to move along the inside of the second mounting plate 3, that is, within the depression groove 71, and compress the second elastic member 73. The trapezoidal insert block 72 will simultaneously drive the limiting block 742 to move. As the L-shaped limiting rod 4 continues to move, the trapezoidal insert block 72 will eventually enter the depression groove 71, and the limiting block 742 will enter the mating groove 11. Then, when the L-shaped limiting rod 4 rotates to the corresponding position of the fixing hole 10 and the trapezoidal insert block 72, the trapezoidal insert block 72 is no longer under pressure. The resilience of the second elastic member 73 will drive the trapezoidal insert block 72 to move outward, and the trapezoidal insert block 72 will enter the fixing hole 10. When the trapezoidal insert block 72 gradually enters the fixing hole 10, the inner wall of the fixing hole 10 will squeeze the limiting block 742, causing the limiting block 742 to enter the inner groove 741 and compress the third elastic member 743. When the trapezoidal insert block 72 returns to its initial position, at this time, the limiting block 742 is not squeezed by the inner wall of the fixing hole 10 either. Then, the resilience of the third elastic member 743 will drive the limiting block 742 to pop out from the inner groove 741, as Figure 6-7 shown in the figure. At this time, the L-shaped limiting rod 4 can be restricted and fixed by the action of the limiting block 742 and the trapezoidal insert block 72. At this time, the first mounting plate 2 and the second mounting plate 3 can be fixed together, that is, two adjacent grille plates 1 are fixed to each other. By analogy, multiple grille plates 1 can be installed.

[0049] Similarly, when disassembling the grille plate 1, the limiting block 742 can be pushed to make it enter the inner groove 741, and at the same time, the trapezoidal insert block 72 is squeezed, so that the trapezoidal insert block 72 and the limiting block 742 enter the fixing hole 10. Then, when the L-shaped limiting rod 4 is rotated simultaneously, the trapezoidal insert block 72 will be squeezed again, making it enter the depression groove 71, so that the L-shaped limiting rod 4 gradually moves away from the second mounting plate 3, that is, the L-shaped limiting rod 4 rotates from the horizontal direction to the vertical direction. At this time, the second mounting plate 3 and the first mounting plate 2 can be separated, that is, the adjacent grille plates 1 can be separated, and the disassembly process is completed.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0051] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
