Technical Field

[0001] The utility model relates to the field of PAC treatment equipment, in particular to a PAC dissolution control box which is convenient for installation. Background Art

[0002] PAC is a solid water purification flocculant. When in use, an automatic dissolution device is required to control the dissolution process, and the automatic dissolution device will be equipped with a PAC dissolution control box.

[0003] The existing PAC dissolution control box is installed and fixed on the wall through expansion bolts. The installation height is generally 1.5 m. An installation piece with an installation hole is welded on the back of the PAC dissolution control box. After driving the expansion bolts into the wall, the PAC dissolution control box is lifted so that the bolts pass through the installation piece, and finally the expansion bolts are tightened to complete the installation and fixation of the PAC dissolution control box.

[0004] The above technical solution has the following defects: during installation, the PAC dissolution control box needs to be pre-lifted to the installation height, and it is necessary to observe and finely adjust the position of the PAC dissolution control box to accurately align the installation holes on the installation piece with the bolts, and then the PAC dissolution control box can be installed in place. Content of the Utility Model

[0005] In order to facilitate the installation and fixation of the PAC dissolution control box, the present application provides a PAC dissolution control box which is convenient for installation.

[0006] The present application provides a PAC dissolution control box which is convenient for installation, and adopts the following technical solution: a PAC dissolution control box which is convenient for installation, including a PAC dissolution control box main body and an installation panel fixed on the wall. A hanging buckle is arranged on the PAC dissolution control box main body, and a hanging seat with a through groove is arranged on the installation panel.

[0007] By adopting the above technical solution, the installation panel is installed on the wall, and the hanging buckle on the PAC dissolution control box main body is matched with the hanging seat on the installation panel, so that the PAC dissolution control box main body can be conveniently hung on the wall without pre-fixing the PAC dissolution control box main body and then using bolts for fastening.

[0008] Optionally, the upper surface of the hanging seat is an inclined surface, and the lowest part of the inclined surface is the part where the through groove is opened.

[0009] By adopting the above technical solution, the inclined surface of the hanging seat can guide the hanging buckle to the lowest part of the inclined surface, that is, to the through groove on the hanging seat, effectively improving the hanging efficiency of the hanging buckle on the hanging seat.

[0010] Optionally, a long strip-shaped convex block is arranged at the edge of the upper surface of the hanging seat, and the upper surface of the hanging seat forms a stepped structure.

[0011] By adopting the above technical solution, the long strip protrusion forms a step-like structure at the edge of the upper surface of the hanger, which effectively prevents the hook from detaching from the hanger when searching for the hanger slot, causing the hanger to fail.

[0012] Optionally, a roller is provided at the free end of the hook.

[0013] By adopting the above technical solution, the roller can reduce the friction resistance between the fixed column and the mounting bracket, so that the hook can be quickly positioned at the through slot opened in the mounting bracket, thereby realizing the mounting of the PAC dissolution control box body.

[0014] Optionally, the hook is slidably connected to the PAC dissolution control box body via a sliding member.

[0015] By adopting the above technical solution, the hanging buckle is slidably connected to the PAC dissolution control box body, so that when the hanging buckle touches the upper plate surface of the hanging seat to find the through groove, the PAC dissolution control box body does not move synchronously with the hanging buckle, and the PAC dissolution control box body will not tilt and rotate and then slip off the hanging seat and fall, thereby improving the stability of the movement of the PAC dissolution control box body during the hanging process.

[0016] Optionally, the sliding member includes a slide rail provided on the PAC dissolution control box body and a slider fixed to the hook, and the slider is slidably connected to the slide rail.

[0017] By adopting the above technical solution and using the movable connection method of the slide rail and the slider, the relative movement of the hook relative to the PAC dissolution control box body is simply and reliably achieved.

[0018] Optionally, a stop block is provided in the middle of the slide rail, and the sliding blocks are distributed on both sides of the stop block.

[0019] By adopting the above technical solution, the blocks distribute the sliders on both sides of the slide rail, effectively guiding the two hooks to approach the through slots on the hook seats to be connected, thereby improving the hooking efficiency of the hooks.

[0020] Optionally, a limiting component is provided on the mount, and the limiting component includes an assembly box mounted on the mount and a paddle hinged to the inside of the assembly box, with the free end of the paddle passing through the assembly box; a limiting rod is hinged to the side of the paddle facing the mount, and the limiting rod passes through the assembly box and the mount; a compression spring is connected to the side of the paddle facing away from the mount; a groove is provided at the contact portion between the hook and the limiting rod.

[0021] By adopting the above technical solution, the limiting rod can pass through the hanging seat and be inserted into the already hung fixed column, so that the fixed column cannot move in the vertical direction, and then the limiting component limits the PAC dissolution control box body in the vertical upward direction.

[0022] Optionally, the contact end face between the limiting rod and the hanging buckle is set as an inclined plane, and the orientation of the inclined plane is consistent with the direction in which the hanging buckle is inserted into the hanging seat.

[0023] By adopting the above technical solution, during the process of the fixing column being inserted into the through groove of the hanging seat, the inclined end face of the limiting rod generates a horizontal component force along the axial direction of the limiting rod on the force vertically downward from the fixing column, so that the limiting rod moves away from the fixing column to realize the yielding of the limiting rod, and the fixing column continues to move downward to realize the hanging connection.

[0024] Optionally, two supporting seats are fixedly connected to the lower part of the mounting panel, and the two supporting seats are at the same horizontal height.

[0025] By adopting the above technical solution, the supporting seats limit the lower part of the main body of the PAC dissolution control box, so that the main body of the PAC dissolution control box cannot shake randomly.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By fixedly connecting the mounting panel to the wall, setting the hanging seat on the mounting panel, and setting the hanging buckle on the main body of the PAC dissolution control box, and the hanging buckle cooperates with the hanging seat, the hanging and fixing of the main body of the PAC dissolution control box on the wall are simply and easily realized;

[0028] 2. By setting the upper surface of the hanging seat as an inclined plane, the inclined plane can guide the hanging buckle to move towards the through groove on the hanging seat, effectively improving the hanging efficiency of the hanging buckle on the hanging seat;

[0029] 3. By arranging a sliding member between the hanging buckle and the main body of the PAC dissolution control box, when the hanging buckle touches the upper plate surface of the hanging seat to find the through groove, the main body of the PAC dissolution control box does not move synchronously with the hanging buckle, improving the smoothness of the movement of the main body of the PAC dissolution control box during the hanging process.

[0035] The following further elaborates on this application in conjunction with the attached drawings.

[0036] This embodiment of the application discloses a PAC dissolution control box that is convenient for installation. As Figure 1 shown, it includes a PAC dissolution control box main body 1 and a rectangular installation panel 2.

[0037] As Figure 1 shown, the PAC dissolution control box main body 1 is a box-shaped structure arranged vertically. Two identically structured hanging buckles 3 are horizontally and evenly distributed on the upper part of the back surface of the PAC dissolution control box main body 1. The hanging buckle 3 includes a connecting column 31 and a fixed column 32. The connecting column 31 is vertically fixed to the back surface of the PAC dissolution control box main body 1, and one end of the fixed column 32 is vertically fixed to the free end of the connecting column 31, with the free end of the fixed column 32 facing the ground.

[0038] As Figure 1 shown, the installation panel 2 is fastened to the wall by bolts at its four corners. The installation panel 2 is in contact with the wall. A hanging seat 4 with a strip-shaped plate structure that cooperates with the hanging buckle 3 is fixed to the upper part of the side wall of the installation panel 2 away from the wall. The hanging seat 4 is perpendicular to the installation panel 2 and is distributed along the horizontal plane. Through grooves perpendicular to the plate surface of the hanging seat 4 are opened at both ends of the hanging seat 4 along its length direction, and the fixed column 32 can be inserted into the through grooves; an inclined surface is opened on the upper plate surface of the hanging seat 4. Taking the vertical plane passing through the center of the hanging seat 4 and perpendicular to the installation panel 2 as the dividing surface, the inclined surfaces are symmetrically distributed on both sides of the dividing surface, extending upward to the dividing surface and downward to the two ends where the through grooves are opened, so that the hanging seat 4 is symmetric about the dividing surface.

[0039] Lift the PAC dissolution control box main body 1 so that the hanging buckles 3 are above the hanging seat 4 and are distributed on both sides of the above-mentioned dividing surface. Slowly lower the PAC dissolution control box main body 1 in the vertical direction. The fixed column 32 contacts the upper surface of the hanging seat 4. If both fixed columns 32 are directly aligned with the through grooves and inserted into the hanging seat 4, the installation of the PAC dissolution control box main body 1 is completed; if the fixed column 32 is not directly aligned with the through groove and contacts the inclined surface of the hanging seat 4, at this time, under the guiding action of the inclined surface of the hanging seat 4 of the PAC dissolution control box main body 1, the fixed column 32 moves to the through groove of the hanging seat 4, the fixed column 32 is inserted into the hanging seat 4, and the PAC dissolution control box main body 1 is hung on the installation panel 2.

[0040] In the process of slowly lowering the main body 1 of the PAC dissolution control box to make the fixing column 32 touch the upper plate surface of the hanging seat 4 and then find the through groove, it may happen that the main body 1 of the PAC dissolution control box moves away from the installation panel 2 due to careless operation. The fixing column 32 will be separated from the upper plate surface of the hanging seat 4, resulting in the failure of hanging the main body 1 of the PAC dissolution control box.

[0041] In order to effectively limit the movement range of the fixing column 32 on the upper plate surface of the hanging seat 4 and make the fixing column 32 not easily slip off the hanging seat 4, as Figure 1 shown, in the embodiment of the present application, a convex block 41 is fixedly connected to the edge of the upper plate surface of the hanging seat 4 away from the installation panel 2, so that the upper plate surface of the hanging seat 4 forms a stepped structure. In the process of the fixing column 32 touching the upper plate surface of the hanging seat 4 to find the through groove, when the fixing column 32 moves away from the installation panel 2 and contacts the convex block 41, the convex block 41 effectively blocks the continuous movement of the fixing column 32, making the fixing column 32 not easily fall off the hanging seat 4.

[0042] In the process of the fixing column 32 touching the upper plate surface of the hanging seat 4 to find the through groove, the lower end surface of the fixing column 32 and the upper end surface of the hanging seat 4 are in sliding friction. In order to reduce the frictional resistance between the fixing column 32 and the hanging seat 4 and make the fixing column 32 quickly locate at the through groove opened on the hanging seat 4, as Figure 1 shown, in the embodiment of the present application, a roller 33 is provided at the lower end of the fixing column 32, and the roller 33 rolls on the hanging seat 4, changing the sliding friction between the fixing column 32 and the hanging seat 4 into rolling friction, reducing the resistance of the fixing column 32 moving on the hanging seat 4.

[0043] In the process of the fixing column 32 touching the upper plate surface of the hanging seat 4 to find the through groove, the main body 1 of the PAC dissolution control box will move synchronously with the fixing column 32. The upper part of the main body 1 of the PAC dissolution control box will be subjected to a horizontal force due to the action of the inclined surface of the hanging seat 4, and the human hand needs to support the main body 1 of the PAC dissolution control box horizontally additionally to keep the main body 1 of the PAC dissolution control box vertical.

[0044] In order to make the main body 1 of the PAC dissolution control box move smoothly during the hanging process of the hanging buckle 3 and improve the safety of installation, as Figure 1 shown, in the embodiment of the present application, a slide rail 5 is horizontally and fixedly connected to the upper part of the back surface of the main body 1 of the PAC dissolution control box, and a slider 6 is fixedly connected to the free end of the connecting column 31 on the hanging buckle 3.

[0045] As Figure 2 shown, the slide rail 5 is a rectangular plate with a cavity, and the cavity of the slide rail 5 penetrates through the side wall of the slide rail 5 away from the main body 1 of the PAC dissolution control box and communicates with the outside; the slider 6 is located in the cavity of the slide rail 5, so that the hanging buckle 3 can move freely on the slide rail 5 along the length direction of the slide rail 5.

[0046] During the process of slowly lowering the main body 1 of the PAC dissolution control box so that the hanging buckle 3 touches the upper plate surface of the hanging seat 4 and then searches for the through slot, the hanging buckle 3 is subjected to a horizontal force from the upper plate surface of the hanging seat 4, and the hanging buckle 3 moves relative to the main body 1 of the PAC dissolution control box. At this time, the main body 1 of the PAC dissolution control box only moves in the vertical direction and will not move with the hanging buckle 3, ensuring the stability of the movement of the main body 1 of the PAC dissolution control box during hanging.

[0047] The two hanging buckles 3 can move freely on the slide rail 5 through the sliders 6 respectively, and there will be a situation where the two hanging buckles 3 are on the same side of the slide rail 5 or close to each other at the same time. At this time, during the process of slowly lowering the main body 1 of the PAC dissolution control box so that the hanging buckle 3 touches the upper plate surface of the hanging seat 4 and then searches for the through slot, the two hanging buckles 3 move to the same side, ultimately resulting in the inability of the two hanging buckles 3 to be hung on the hanging seat 4.

[0048] To ensure that both hanging buckles 3 are successfully hung, as Figure 1 shown, in the embodiment of the present application, a stop block 7 is provided in the middle of the slide rail 5. The stop block 7 divides the cavity into two parts, and the two sliders 6 are distributed on both sides of the stop block 7, so that one hanging buckle 3 can only move on the slide rail 5 on one side of the stop block 7, and the other hanging buckle 3 can only move on the slide rail 5 on the other side of the stop block 7, and the two hanging buckles 3 cannot contact each other. When performing the hanging operation, the main body 1 of the PAC dissolution control box is lifted so that the hanging buckle 3 is above the hanging seat 4. Due to the separation of the stop block 7, the hanging buckles 3 are respectively on two inclined surfaces of the hanging seat 4. When hanging, the two hanging buckles 3 move in opposite directions and are respectively hung on the hanging seat 4 through the through slots on the hanging seat 4.

[0049] As Figure 1 shown, in the embodiment of the present application, a limit component 8 is provided on the hanging seat 4, and the limit component 8 limits the main body 1 of the PAC dissolution control box in the vertically upward direction. As Figure 3 shown, the limit component 8 includes an assembly box 81 with a cavity, a dial 82, a compression spring 83, and a limit rod 84 passing through the assembly box 81 and the hanging seat 4. The assembly box 81 is fixedly connected to the side wall of the hanging seat 4. One end of the dial 82 is rotatably connected to the inner wall of the cavity of the assembly box 81 through a hinge. The free end of the dial 82 passes through the side wall of the assembly box 81, and the free end of the dial 82 is located outside the assembly box 81. The dial 82 can rotate around the hinge within a certain angle range; the limit rod 84 is horizontally arranged in the assembly box 81. One end of the limit rod 84 is hinged to the dial 82, and the other end passes through the assembly box 81 and the hanging seat 4 in sequence until it abuts against the fixed column 32. A groove is provided at the contact part of the fixed column 32 and the limit rod 84, and the limit rod 84 can be inserted into the fixed column 32, so that the hanging buckle 3 cannot be detached from the hanging seat 4.

[0050] As Figure 3As shown, the compression spring 83 is located within the assembly box 81. One end of the compression spring 83 abuts against the wall of the paddle 82 away from the limiting rod 84, and the other end abuts against the inner wall of the assembly box 81 away from the hanger 4. The compression spring 83 exerts a force on the paddle 82 to cause the limiting rod 84 to move toward the fixed column 32, so that the limiting rod 84 is inserted into the fixed column 32 and is not easily disengaged, thereby improving the limiting stability of the limiting rod 84. When the free end of the paddle 82 is toggled, the paddle 82 rotates, driving the limiting rod 84 to insert into the fixed column 32 or move away from the fixed column 32.

[0051] like Figure 3 As shown, in the natural state, the compression spring 83 pushes the paddle 82 so that the contact end of the limiting rod 84 with the fixed rod is located in the through-slot of the hanger 4. In the embodiment of the present application, the end surface of the limiting rod 84 at the contact end with the fixed column 32 is configured as an inclined surface, and the orientation of the inclined surface is consistent with the direction in which the hook 3 is inserted into the hanger 4. During the process of inserting the fixed column 32 into the through-slot of the hanger 4, when the fixed column 32 abuts the inclined end surface of the limiting rod 84, the inclined end surface of the limiting rod 84 will convert the vertical downward force from the fixed column 32 into a horizontal component of force on the limiting rod 84 along the axial direction of the limiting rod 84, causing the limiting rod 84 to move away from the fixed column 32 until the limiting rod 84 is completely out of position and the fixed column 32 continues to move downward. At the same time, the limiting rod 84 squeezes the compression spring 83 through the paddle 82. When the groove on the limiting rod 84 is at the same level as the limiting rod 84 , the groove provides space for the limiting rod 84 , and the limiting rod 84 is inserted into the limiting rod 84 by the force of the compression spring 83 through the paddle 82 .

[0052] The PAC dissolution control box body 1 is hung on the installation panel 2 through the hanging buckle 3. Since the hanging buckle 3 is set on the upper part of the PAC dissolution control box body 1, the lower part of the PAC dissolution control box body 1 is in a free hanging state and is prone to shaking. In order to make the PAC dissolution control box body 1 more firmly set on the installation panel 2, as shown in the following figure: Figure 1 As shown, in the embodiment of the present application, support bases 9 are fixedly connected to the two corners of the lower part of the mounting panel 2. The support base 9 is composed of two rectangular plates that are perpendicular to each other and fixed together. The support base 9 covers the two corners of the lower part of the PAC dissolution control box body 1. The support base 9 assists in supporting the PAC dissolution control box body 1 and limits the lower part of the PAC dissolution control box body 1 in the horizontal direction, so that the PAC dissolution control box body 1 cannot shake at will.

[0053] The use process of this utility model is:

[0054] Fix the installation panel 2 to the wall with expansion bolts, lift the PAC dissolution control box body 1 so that the hook 3 is above the mount 4, slowly lower the PAC dissolution control box body 1 so that the two rollers 33 respectively contact the two inclined surfaces of the mount 4, and the two hooks 3 move toward the two ends of the mount 4 with through grooves, and the PAC dissolution control box body 1 moves vertically downward smoothly.

[0055] When the fixing post 32 is inserted into the mount 4 and contacts the oblique end surface of the limiting rod 84, the limiting rod 84 moves away from the fixing post 32 until it has given way, and the fixing post 32 continues to move downward. When the groove on the limiting rod 84 is at the same level as the limiting rod 84, the groove provides space for the limiting rod 84 to give way. The limiting rod 84 is inserted into the limiting rod 84 by the force of the compression spring 83 through the paddle 82. The limiting assembly 8 locks the hook 3 on the mount 4. At the same time, the lower part of the PAC dissolution control box body 1 contacts the support base 9, and the PAC dissolution control box body 1 is installed.

[0056] If the PAC dissolution control box body 1 needs to be disassembled, push the paddle 82 away from the mount 4. The paddle 82 drives the limit rod 84 to disengage from the fixed column 32. Lift the PAC dissolution control box body 1 and pull the hook 3 out of the mount 4 to complete the disassembly of the PAC dissolution control box body 1.

[0057] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
