Description

TECHNICAL FIELD

[0001] The utility model relates to a self-priming pump cover body technical field, especially in improving the self-priming pump cover body of sealing reliability. BACKGROUND

[0002] The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable running, easy maintenance, high efficiency, long service life and strong self-priming capacity. The pipeline does not need to be installed with a bottom valve, and only a certain amount of priming liquid needs to be stored in the pump body before work. Different liquids can use self-priming pumps of different materials. The pump cover plays an important role in the entire self-priming pump. The existing equipment is generally tightened and fixed by bolts during installation. During installation, the equipment needs to be manually tightened by a wrench, and multiple bolts need to be tightened, which consumes a long time, reduces the installation efficiency of the equipment, and increases the labor intensity of the operator, causing a large burden on the body.

[0003] In the Chinese utility model patent with publication number CN218669937U, a pump cover mechanism of a self-priming pump is disclosed, which relates to the technical field of water pump covers. The utility model includes a cover body fixing assembly, which includes a ring-shaped handle for the operator to operate. The ring-shaped handle is connected with a transmission driving link. The transmission driving link is connected with a gear. The gear is connected with a rack that is meshed with the gear. The rack is connected with a limit slide block. The limit slide block is shaped as an inverted convex type. The rack is connected with a limit fixing rod that fixes the pump cover body. One end of the limit fixing rod can extend one centimeter beyond the range of the buckle ring. The utility model sets up the cover body fixing assembly, which can save a lot of operation time during installation, reduce the physical burden of the operator, improve the installation efficiency of the equipment, and prepare for subsequent work in advance.

[0004] According to the related technology in the above, the inventors believe that the following defects exist: The above device drives the limit fixing rod to move by rotating the ring-shaped handle, and then fixes the pump cover body. In actual use, the operator needs to repeatedly adjust the position of the pump cover body before rotating the ring-shaped handle, which reduces the user experience. UTILITY MODEL CONTENTS

[0005] In order to solve the above problems, the utility model provides a self-priming pump cover body that improves the sealing reliability.

[0006] The technical scheme of the above technical purpose is achieved by the following technical scheme: the self-priming pump cover body improving sealing reliability, comprising a pump cover main body, a fixed block is fixed on the side wall of the pump cover main body, an auxiliary handle for reducing the difficulty of moving the pump cover main body by workers is arranged on the fixed block, a fixed plate is fixed on the bottom surface of the pump cover main body, a fixed ring is fixed on the bottom surface of the pump cover main body, an indicating groove is formed in the bottom surface of the fixed ring, an indicating rod is slidably arranged in the indicating groove, and a fixing assembly for fixing the pump cover main body is arranged on the fixed plate.

[0007] When the workers need to seal the self-priming pump, the workers need to connect the indicating rod with the self-priming pump in advance, and connect the indicating rod with the indicating groove, so that the pump cover main body and the self-priming pump are connected and preliminarily kept stable. Further, the workers only need to move the self-priming pump downward and open the fixing assembly, so that the fixing assembly fixes the pump cover main body, thereby keeping the pump cover main body stable, and reducing the difficulty of the workers in installing the pump cover main body, thereby improving the use experience of the workers.

[0008] Further, a first fixing groove is formed in the side wall of the fixed plate, a second fixing groove is formed in the side wall of the fixed ring and communicates with the first fixing groove, the fixing assembly comprises a fixing rod which is slidably arranged in the first fixing groove and the second fixing groove, a compression spring which is fixed at one end on the side wall of the fixing rod, and a connecting rope which is fixed at one end on the side wall of the fixing rod close to the fixed spring, and the other end of the compression spring is fixed on the inner wall of the first fixing groove away from the second fixing groove.

[0009] Further, a first rotating groove is formed in the upper surface of the pump cover main body, a second rotating groove is formed in the upper surface of the fixed plate, and a rotating rod is rotatably arranged in the first rotating groove and the second rotating groove, and one end of the connecting rope away from the fixing rod is fixed with the rotating rod.

[0010] Further, a limiting block is fixed on the bottom surface of the rotating rod, and a limiting hole matched with the limiting block is formed in the inner bottom wall of the second rotating groove.

[0011] When the staff needs to install the pump cover body, the staff needs to rotate the rotating rod, so that the connecting rope is gradually wound on the rotating rod, so that the fixing rod is completely moved into the first fixing groove and the second fixing groove. Then, the staff needs to press the rotating rod downward, so that the limiting block and the limiting hole are connected with each other, so that the rotating rod remains stable. Further, the staff needs to connect the indicating rod with the indicating groove, and press the pump cover body downward, so that the fixing rod gradually moves downward, and when the pump cover body abuts against the self-priming pump, the fixing rod is opposite to the fixing hole preformed on the self-priming pump. At this time, the staff needs to pull the rotating rod upward, so that the limiting block and the limiting hole are separated from each other. Further, the staff only needs to loosen the rotating rod, so that the fixing rod is reset under the action of the compression spring, so that the fixing rod is connected with the fixing hole preformed on the self-priming pump, so that the fixing rod limits the pump cover body, and the pump cover body remains stable.

[0012] Further, the inner top wall of the first fixing groove is threadedly connected with a threaded rod, the upper end of the threaded rod extends to the outside of the pump cover body, the upper surface of the fixing rod is provided with a placing groove, and an inclined surface is formed on the edge where the inner wall of the placing groove far away from the compression spring intersects with the upper surface of the fixing rod.

[0013] Further, the bottom surface of the threaded rod is fixed with a silica gel block.

[0014] By adopting the above technical scheme, when the staff connects the fixing rod with the fixing hole preformed on the self-priming pump, the staff only needs to rotate the threaded rod, so that the threaded rod moves downward. If the fixing rod does not move to the farthest end at this time, the silica gel block moves downward and abuts against the inclined surface, so that the fixing rod continues to move away from the rotating rod, thereby reducing the difficulty of the staff installing the fixing rod.

[0015] Further, the inner bottom wall of the placing groove is provided with a containing groove matched with the silica gel block.

[0016] By adopting the above technical scheme, when the fixing rod continues to move away from the rotating rod under the action of the silica gel block, the staff only needs to continue to rotate the threaded rod, so that the silica gel block is connected with the containing groove, so that the silica gel block blocks the fixing rod, thereby reducing the probability of the fixing rod resetting at this time.

[0017] Further, the upper end of the threaded rod is fixed with a handle for reducing the difficulty of the staff rotating the threaded rod.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. In this application, when the operator needs to seal the self-priming pump, the operator must first connect the indicator rod to the self-priming pump and the indicator groove to connect the pump cover body to the self-priming pump and initially stabilize it. Furthermore, the operator only needs to move the self-priming pump downwards and open the fixing component to fix the pump cover body, thus stabilizing it. This reduces the difficulty of installing the pump cover body and improves the user experience.

[0020] 2. In this application, when the operator needs to install the pump cover body, the operator needs to rotate the rotating rod so that the connecting rope gradually winds around the rotating rod, thereby moving the fixing rod completely into the first fixing groove and the second fixing groove. Then, the operator needs to press down on the rotating rod to connect the limiting block and the limiting hole, thus stabilizing the rotating rod. Further, the operator needs to connect the indicator rod and the indicator groove, and press down on the pump cover body to move the fixing rod gradually downwards. When the pump cover body is pressed against the self-priming pump, the fixing rod aligns with the pre-drilled fixing hole on the self-priming pump. At this point, the operator needs to pull the rotating rod upwards to separate the limiting block from the limiting hole. Further, the operator only needs to release the rotating rod to reset the fixing rod under the action of the compression spring, thereby connecting the fixing rod with the pre-drilled fixing hole on the self-priming pump, thus limiting the pump cover body and stabilizing it.

[0021] 3. In this application, after the worker connects the fixing rod to the pre-drilled fixing hole on the self-priming pump, the worker only needs to rotate the threaded rod to move the threaded rod downwards. If the fixing rod has not moved to its farthest end at this time, the silicone block moves downwards and presses against the inclined surface, thereby causing the fixing rod to continue moving away from the rotating rod, thus reducing the difficulty for the worker to install the fixing rod.

Obviously, the described embodiments are only part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0029] As Figures 1-5 shown, the present application discloses a self-priming pump cover body for improving sealing reliability, which comprises a pump cover body 1, a fixed block 11, an auxiliary handle 12, a fixed plate 2, a fixed ring 21, an indicating rod 31, a fixed assembly 4, a rotating rod 6, a limiting block 61, a threaded rod 8, a silica gel block 82 and a handle 9. The fixed block 11 is a rectangular block structure, and the fixed block 11 is fixed on the side wall of the pump cover body 1. The auxiliary handle 12 is arranged on the fixed block 11, which is used to reduce the difficulty of moving the pump cover body 1 for the workers. The fixed plate 2 is a circular plate structure, and the fixed plate 2 is fixed on the bottom surface of the pump cover body 1. The fixed ring 21 is a plate structure with a circular cross section, and the fixed ring 21 is fixed on the bottom surface of the pump cover body 1. The bottom surface of the fixed ring 21 is provided with an indicating groove 3, and the indicating rod 31 is a rectangular rod structure, and the indicating rod 31 is slidingly arranged in the indicating groove 3.

[0030] The side wall of the fixing plate 2 is provided with a first fixing groove 32, and the side wall of the fixing ring 21 is provided with a second fixing groove 33 penetrating through and communicating with the first fixing groove 32. The fixing assembly 4 is arranged on the fixing plate 2 and used for fixing the pump cover body 1. The fixing assembly 4 comprises a fixing rod 41, a compression spring 42 and a connecting rope 43. The fixing rod 41 is a rectangular rod structure, and the fixing rod 41 is arranged in the first fixing groove 32 and the second fixing groove 33 in a sliding mode. One end of the compression spring 42 is fixed on the side wall of the fixing rod 41, and the other end of the compression spring 42 is fixed on the inner wall of the first fixing groove 32 away from the second fixing groove 33. One end of the connecting rope 43 is fixed on the side wall of the fixing rod 41 close to the fixing spring. The upper surface of the pump cover body 1 is provided with a first rotating groove 5, and the upper surface of the fixing plate 2 is provided with a second rotating groove 51. The rotating rod 6 is a circular rod structure, and the rotating rod 6 is arranged in the first rotating groove 5 and the second rotating groove 51 in a rotating mode. The end of the connecting rope 43 away from the fixing rod 41 is fixed to the rotating rod 6.

[0031] The limiting block 61 is a block structure, and the limiting block 61 is fixed on the bottom surface of the rotating rod 6. The inner bottom wall of the second rotating groove 51 is provided with a limiting hole 7 matched with the limiting block 61.

[0032] When the staff needs to install the pump cover body 1, the staff needs to rotate the rotating rod 6, so that the connecting rope 43 is gradually wound on the rotating rod 6, so that the fixing rod 41 is completely moved into the first fixing groove 32 and the second fixing groove 33. Then, the staff needs to press the rotating rod 6 downward, so that the limiting block 61 and the limiting hole 7 are connected with each other, so that the rotating rod 6 remains stable. Further, the staff needs to connect the indicating rod 31 with the indicating groove 3, and press the pump cover body 1 downward, so that the fixing rod 41 moves downward gradually. When the pump cover body 1 abuts against the self-priming pump, the fixing rod 41 is opposite to the fixing hole pre-provided on the self-priming pump. At this time, the staff needs to pull the rotating rod 6 upward, so that the limiting block 61 and the limiting hole 7 are separated from each other. Further, the staff only needs to release the rotating rod 6, so that the fixing rod 41 is reset under the action of the compression spring 42, so that the fixing rod 41 is connected with the fixing hole pre-provided on the self-priming pump, so that the fixing rod 41 limits the pump cover body 1, so that the pump cover body 1 remains stable.

[0034] When the staff connects the fixed rod 41 with the fixed hole on the self-priming pump, the staff only needs to rotate the threaded rod 8, so that the threaded rod 8 moves downward. If the fixed rod 41 does not move to the farthest end at this time, the silica gel block 82 moves downward and abuts against the inclined surface, so that the fixed rod 41 continues to move away from the rotating rod 6, thereby reducing the difficulty of the staff installing the fixed rod 41.

[0035] In order to reduce the probability of the fixed rod 41 resetting, the inner bottom wall of the installation groove 81 is provided with a containing groove 83 matched with the silica gel block 82. When the fixed rod 41 continues to move away from the rotating rod 6 under the action of the silica gel block 82, the staff only needs to continue to rotate the threaded rod 8, so that the silica gel block 82 is connected with the containing groove 83, thereby the silica gel block 82 blocks the fixed rod 41, and the probability of the fixed rod 41 resetting is reduced.

[0036] In order to reduce the difficulty of the staff rotating the threaded rod 8, the upper end of the threaded rod 8 is fixed with a handle 9.

[0037] The use principle of the self-priming pump cover body for improving sealing reliability in the embodiment is that when the staff needs to seal the self-priming pump, the staff needs to connect the indicating rod 31 with the self-priming pump in advance, and connect the indicating rod 31 with the indicating groove 3, so that the pump cover body 1 is connected with the self-priming pump and preliminarily kept stable. Further, the staff only needs to move the self-priming pump downward and open the fixing assembly 4, so that the fixing assembly 4 fixes the pump cover body 1, thereby the pump cover body 1 is kept stable, and the difficulty of the staff installing the pump cover body 1 is reduced, thereby the use experience of the staff is improved.
