Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and relates to a horizontal water pump, and more particularly to a horizontal water pump coupling cover installation structure. Background Technology

[0002] A horizontal water pump is a type of water pump, and its structure is as disclosed in the Chinese Patent Database as a horizontal water pump with safety protection (CN220059937U). It includes a drive motor, a motor coupling, a transmission shaft, a pump body coupling, and a water pump. It also includes a protective mechanism and a base mechanism. The protective mechanism includes a support frame and a U-shaped guard plate. One end of the support frame is connected to the side wall of the pump body, and the other end is fixed with a side bracket. The support frame has a cylindrical structure and contains a bearing assembly connected to the transmission shaft. The U-shaped guard plate is located between the support frame and the drive motor, with a semi-circular upper section and two unobstructed side plates at the bottom, protecting the motor coupling and transmission shaft. The base mechanism includes a base plate, a motor base, a pump body base, a support base, and a guard plate base.

[0003] In the aforementioned horizontal water pump, the U-shaped protective plate is used to cover the pump body coupling, eliminating the safety hazards caused by the high-speed rotation of the pump body coupling. As shown in the attached drawings of the patent, the U-shaped protective plate is fixed to the base mechanism with multiple screws. This method requires tightening or loosening multiple screws during use, making the operation rather cumbersome. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a horizontal water pump coupling cover installation structure that facilitates the disassembly and assembly of the cover.

[0005] The objective of this utility model can be achieved through the following technical solution: a horizontal water pump coupling cover mounting structure, comprising a base frame and a cover body in the shape of an inverted U, mounted on the base frame. Both ends of the cover body are bent outwards to form horizontally arranged pressure plate portions. The characteristic feature is that an inverted U-shaped support seat is provided between the two pressure plate portions and the base frame. The support seat is fixed to the base frame, and the two pressure plate portions respectively press against the top walls of the two support seats. Both pressure plate portions extend downwards to form baffle portions, and the two support... The two sides of the seat, which are far apart, press against the two baffles respectively; the two baffles are respectively provided with through holes and threaded holes, and the axes of the through holes and threaded holes extend along the arrangement direction of the two support seats; a screw is inserted in the through hole, and the screw shank passes through the through hole and the inner cavity of the two support seats in sequence and is screwed into the aforementioned threaded hole, with the screw head tightly pressed against the corresponding baffle; a positioning rod is vertically fixed on each of the two pressure plates, and the support seat has a vertical insertion hole that matches the positioning rod, and the two positioning rods are respectively inserted into the two insertion holes.

[0006] During installation, the main body of the protective cover is fitted over the coupling. The support base, pressure plate, through hole, threaded hole, and screws work together to restrict the vertical movement of the main body of the protective cover. The positioning rod and insertion hole work together to restrict the horizontal movement of the main body of the protective cover along its own axis. The baffle and support base work together to restrict the forward and backward movement of the main body of the protective cover, thereby locking the main body of the protective cover on the base frame to effectively protect the coupling.

[0007] In this application, the disassembly and assembly of the cover can be completed by removing and installing screws and lifting or pressing down the main body of the cover. The entire disassembly and assembly process has few steps and has the advantages of being convenient and easy, thus facilitating the maintenance of the coupling.

[0008] In the above-mentioned horizontal water pump coupling cover installation structure, there is a certain distance between the screw rod and the top wall of the support base, and the distance between the screw rod and the top wall of the support base is less than the length of the positioning rod extending into the insertion hole. In this way, even if the cover moves upward a certain distance due to an external force collision, the positioning rod will not completely extend out of the insertion hole, ensuring that the cover body can be quickly and accurately reset later.

[0009] In the aforementioned horizontal water pump coupling cover installation structure, the support base consists of an inverted U-shaped base body and a rubber pad fixed against the top wall of the base body. The shank of the aforementioned screw passes through the inner cavity of the base body, the aforementioned pressure plate presses against the rubber pad, and the two ends of the aforementioned insertion hole are respectively located on the corresponding rubber pad and the corresponding base body. The rubber pad increases the friction between the pressure plate and the support base, strengthening the positioning strength and stability of the cover body, and also reduces the installation noise of the support base.

[0010] In the above-mentioned horizontal water pump coupling cover installation structure, a handle is fixed on the top wall of the cover body to facilitate lifting or pressing the cover body, which is conducive to the disassembly and assembly of the cover body.

[0011] In the above-mentioned horizontal water pump coupling cover installation structure, both ends of the cover body are densely covered with air holes, the air hole axes are set horizontally, and the air holes extend axially along the arrangement direction of the two support seats.

[0012] In the above-mentioned horizontal water pump coupling cover installation structure, the main body of the cover is an integral structure.

[0013] Compared with existing technologies, the mounting structure of this horizontal water pump coupling cover has the following advantages: 1. In this application, the disassembly and assembly of the cover can be completed by removing and installing screws and lifting or pressing down the main body of the cover. The entire disassembly and assembly process has few steps and has the advantages of being convenient and easy to disassemble and assemble, thus facilitating the maintenance of the coupling.

[0014] 2. The rubber pads not only increase the friction between the pressure plate and the support base, enhancing the positioning strength and stability of the main body of the cover, but also reduce the installation noise of the support base. Attached Figure Description

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 As shown, the mounting structure for the horizontal water pump coupling cover includes a base frame 1 and a cover body 2, which is mounted on the base frame 1 and is inverted U-shaped. During actual installation, the cover body 2 is fitted over the coupling to cover it, thereby eliminating the safety hazards caused by the high-speed rotation of the coupling.

[0021] in, Both ends of the protective cover body 2 are bent outward to form horizontally arranged pressure plate portions 2a. The pressure plate portions 2a are elongated strips, and their length extends along the axial direction of the protective cover body 2. An inverted U-shaped support seat 3 is provided between each of the two pressure plate portions 2a and the base frame 1, and the arrangement direction of the two support seats 3 is perpendicular to the axial direction of the protective cover body 2. The support seats 3 are fixed to the base frame 1, and the two pressure plate portions 2a respectively press against the top walls of the two support seats 3.

[0022] like Figures 1 to 3 As shown, both pressure plate portions 2a extend downwards to form baffle portions 2b. The baffle portions 2b are elongated, their length extending axially along the main body 2 of the cover. The two support seats 3, located on opposite sides, press against the two baffle portions 2b. Each baffle portion 2b has a through hole and a threaded hole; one baffle portion 2b has a through hole, and the other has a threaded hole. The axes of both the through hole and the threaded hole extend along the arrangement direction of the two support seats 3. A screw 4 passes through the through hole, its shank passing through the through hole and the inner cavity of the two support seats 3, and then screwed into the threaded hole. The head of the screw 4 is pressed tightly against the corresponding baffle portion 2b. Positioning rods 5 are vertically fixed to both pressure plate portions 2a. Each support seat 3 has a vertically penetrating insertion hole matching the positioning rod 5, and the two positioning rods 5 are respectively inserted into the two insertion holes.

[0023] During installation, the support base 3, pressure plate 2a, through hole, threaded hole and screw 4 work together to restrict the up and down movement of the protective cover body 2; the positioning rod 5 and the insertion hole work together to restrict the left and right movement of the protective cover body 2 along its own axis; the baffle 2b and the support base 3 work together to restrict the front and back movement of the protective cover body 2, thereby locking the protective cover body 2 on the base frame 1 to effectively protect the coupling.

[0024] In this application, the disassembly and assembly can be completed by removing and installing screws 4 and lifting or pressing down the main body 2 of the cover. The entire disassembly and assembly process has few steps and has the advantages of being convenient and easy to disassemble and assemble, thus facilitating the maintenance of the coupling.

[0025] In actual design, there is a certain distance between the screw 4 rod and the top wall of the support 3, which is 0.5mm to 0.8mm. Although this distance design will cause the main body of the cover 2 to wobble slightly when hit by external force, it will not affect the main body of the cover 2 from covering the coupling. On the contrary, this distance design can greatly reduce the requirements for the fit accuracy of each component and reduce the processing difficulty.

[0026] The distance between the screw 4 rod and the top wall of the support base 3 is preferably less than the length of the positioning rod 5 extending into the insertion hole. This way, even if the cover is impacted by an external force and moves upward a certain distance, the positioning rod 5 will not completely extend out of the insertion hole, ensuring that the cover body 2 can be quickly and accurately reset later.

[0027] In this embodiment, like Figure 3 As shown, the support base 3 has the following specific structure: The support base 3 consists of an inverted U-shaped base body 3a and a rubber pad 3b fixed to the top wall of the base body 3a. The shank of the screw 4 passes through the inner cavity of the base body 3a; the pressure plate 2a presses against the rubber pad 3b, and the two ends of the aforementioned insertion hole are respectively located on the corresponding rubber pad 3b and the corresponding base body 3a. The rubber pad 3b increases the friction between the pressure plate 2a and the support base 3, strengthening the positioning strength and stability of the protective cover body 2, and also reduces installation noise of the support base 3. Preferably, the rubber pad 3b is fixed to the top wall of the base body 3a by adhesive bonding.

[0028] Both ends of the protective cover body 2 are densely covered with air holes 2c. The axis of the air holes 2c is horizontally set, and the axial direction of the air holes 2c extends along the arrangement direction of the two support seats 3.

[0029] In the actual product, a handle 6 is fixed on the top wall of the protective cover body 2 to facilitate lifting or pressing the protective cover body 2, and to facilitate the assembly and disassembly of the protective cover body 2. The protective cover body 2 is a one-piece structure.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
