Description

Technical Field

[0001] This utility model relates to the field of pump body structure technology, and in particular to a pump cover mounting structure. Background Technology

[0002] The internal components of the pump cover require regular maintenance to ensure the equipment operates normally. Taking the milk tea industry as an example, a typical milk tea shop has one or more machines, each containing 10-20 pumps. To avoid disrupting normal business operations, maintenance is usually scheduled after closing time in the evening. At this time, shop staff are eager to leave, while maintenance personnel need to maintain multiple shops simultaneously. Maintenance tasks are characterized by short timeframes and heavy workloads.

[0003] Existing pump cover fixing methods mainly employ bolt fixing and clip fixing. Bolt fixing is time-consuming and labor-intensive when installing and removing the pump cover, and there is a risk of bolts being lost. Clip fixing, when the clip design has little deformation space, makes the pump head difficult to remove, and workers are prone to damaging the clips due to forceful removal. When the clip design has large deformation space, the pump cover is prone to falling off, leading to poor product performance. Furthermore, the pump vibrates significantly during operation. Finding a balance between preventing falling off and facilitating easy installation and removal in the pump head clip design is quite difficult.

[0004] Therefore, there is an urgent need for an efficient, convenient, safe and reliable pump cover disassembly and installation structure. Utility Model Content

[0010] Preferably, one end of the elongated slot has a clearance hole so that the limiting member can pass through the clearance hole.

[0011] Preferably, the locking structure further includes a mounting bracket formed on the base, and the mounting bracket is provided with two limiting blocks; when the sliding part is in the locked position, the free end of the lever is limited to one of the limiting blocks; when the sliding part is in the unlocked position, the free end of the lever is limited to the other limiting block.

[0017] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0018] 1. When disassembling the pump cover, traditional bolt-fixing methods require workers to manually unscrew each bolt, which is time-consuming, labor-intensive, and prone to bolt loss. The new structure of this application, however, only requires moving the sliding part to the unlocked position to release the vertical restriction, allowing the top cover to be removed.

Detailed Implementation

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0032] Reference Figures 1 to 7As shown, this utility model embodiment provides a pump cover mounting structure, which mainly includes an upper cover 1, a base 2, and a locking structure.

[0033] The base 2 has a limiting structure. When the upper cover 1 is installed on the base 2, the limiting structure fits against the upper cover 1 to limit the upper cover 1 and the base 2 in a direction parallel to the mounting surface of the base 2 (the mounting surface of the base is the plane in which the upper cover and the base fit together during installation, generally assumed to be horizontal). The upper cover 1 can be quickly aligned with the base 2 during installation, reducing horizontal adjustment time and improving installation efficiency. Moreover, compared to the need for manual comparison of bolt hole positions during bolt fixing, this limiting method is more intuitive and convenient, reducing installation difficulty. Specifically, the limiting structure includes a barrier 22 formed on the outer edge of the base 2 and adapted to the outer contour of the upper cover 1, and a mounting bracket 5 formed on the base 2. The inner wall of the enclosure 22 is the limiting wall 221, which fits against the outer surface of the cover. When the cover 1 is installed on the base 2, the top of the enclosure 22 abuts against the stepped wall of the cover 1 to limit the cover 1 in the horizontal direction perpendicular to the base 2.

[0034] The locking structure is configured with at least one set, which includes at least one sliding part 4 mounted on the base 2 and movable between a locked position and an unlocked position. In the locked position, the sliding part 4 engages with the limiting part 11, limiting the upper cover 1 and the base 2 in a direction perpendicular to the mounting surface of the base 2. In the unlocked position, the sliding part 4 disengages from the limiting part 11, releasing the limitation between the upper cover 1 and the base 2 in a direction perpendicular to the mounting surface of the base 2. During actual installation, when the sliding part 4 is moved to the locked position, it engages with the limiting part 11 of the upper cover 1 in a vertical direction. This design utilizes a simple mechanical structure to replace bolt tightening, eliminating the need for specialized tools such as screwdrivers and wrenches. Workers can easily move the sliding part 4 by hand to quickly lock the upper cover 1 and the base 2, greatly simplifying the operation process.

[0035] In summary, in this embodiment, when the pump cover needs to be disassembled, the traditional bolt fixing method requires workers to unscrew each bolt by hand, which is time-consuming and prone to losing bolts. However, this new structure only requires gently moving the sliding part to the unlocked position to release the vertical restriction, and then the upper cover 1 can be removed. The entire disassembly process is quick, saving time and reducing the risk of damage to the pump body due to improper tool operation. Especially in the daily inspection and maintenance of pump equipment, maintenance personnel do not need to carry cumbersome tools and can quickly disassemble and install the pump cover by hand, shortening equipment downtime and improving maintenance efficiency.

[0036] In other practical applications, the locking structure also includes a lever 3 rotatably connected to the base 2 at one end. The sliding part 4 slides with the lever 3, so that the sliding part 4 can be switched between a locked position and an unlocked position by swinging the lever 3. The lever 3 is usually connected by a rotatable connection, that is, one end of the lever 3 has a pivot 31, which is rotatably connected to the mounting hole 21 on the base 2. The lever design changes the operator's operating method, that is, the sliding part can be switched between the locked and unlocked positions simply by swinging the lever, further improving the convenience of operation.

[0037] Reference Figures 3 to 7 As shown, in some practical applications, based on the aforementioned lever, the locking structure further includes a mounting bracket 5 formed on the base 2, with two limiting blocks 51 provided on the mounting bracket 5. When the sliding part 4 is in the locked position, the free end of the lever 3 is limited to one of the limiting blocks 51; when the sliding part 4 is in the unlocked position, the free end of the lever 3 is limited to the other limiting block 51. Specifically, the free end of the lever can be configured as an elastic part 32. The lever 3 moves such that the elastic part 32 contacts one of the limiting blocks 51 and undergoes elastic deformation to pass over the limiting block 51, so that the sliding part 4 moves with the lever 3 and is placed in the locked position; the lever 3 moves such that the elastic part 32 contacts the other limiting block 51 and undergoes elastic deformation to pass over the limiting block 51, so that the sliding part 4 moves with the lever 3 and is placed in the unlocked position.

[0038] In addition, the sliding part 4 is mounted on the mounting bracket 5 and can slide relative to the mounting bracket 5 in a direction parallel to the mounting surface of the base 2 between the locked position and the unlocked position; when the sliding part 4 is in the locked position, it abuts against one side of the mounting bracket 5, and when the sliding part 4 is in the unlocked position, it abuts against the other side of the mounting bracket 5, that is, when the sliding part 4 is in the unlocked position, the sliding part 4 disengages from the limiting part 11.

[0039] Therefore, when it is necessary to place the sliding part 4 in the locked position, the lever 3 is pushed to move, and the elastic part 32 on the lever 3 (i.e., as shown) Figure 6The hollow internal structure shown is generally made of plastic, thus possessing a certain degree of elastic deformation capability. It gradually approaches one of the arc-shaped limiting blocks 51 on the mounting bracket 5. Because the limiting block 51 is arc-shaped, as the lever 3 continues to move, the elastic part 32 begins to contact the limiting block 51, undergoing elastic deformation due to the arc-shaped compression. Utilizing the properties of the elastic material, after passing the limiting block 51, the elastic potential energy is released, and the elastic part 32 rebounds. At this point, the sliding part 4 is firmly in the locked position, and the sliding part 4 also vertically limits the limiting part 11 of the upper cover 1, making the locking state more stable and preventing the sliding part 4 from easily disengaging from the locked position due to accidental shaking of the lever 3. To unlock, the lever 3 is moved in the opposite direction, and the elastic part 32 moves towards the other arc-shaped limiting block 51. Similarly, during the contact process, the elastic part 32 is compressed and deformed, and after accumulating energy, it passes over the limit block 51. The movement of the lever 3 allows the sliding part 4 to smoothly enter the unlock position, releasing the vertical limit between the sliding part 4 and the limit part 11.

[0040] Furthermore, when the operator moves the lever 3, they can clearly feel the process of the elastic part 32 contacting, deforming, and passing over the limiting block 51, and will receive obvious tactile feedback. This clear tactile feedback allows the user to confirm whether the lever 3 is in position without looking down, greatly improving the operating experience. In addition, because of the presence of the elastic part 32, the deformation force of the elastic part 32 must be overcome to switch the position of the lever 3. Slight collisions and shaking in daily life are unlikely to cause the lever 3 to move accidentally, ensuring the stability of the pump cover installation.

[0041] Based on the above-mentioned movable connection between the sliding part 4 and the lever 3, in some practical applications, the following method can be used: the lever 3 is provided with a long slot 33 extending along its length direction, and the sliding part 4 is connected with a guide rod 41, which passes through the long slot 33 to realize the sliding cooperation between the sliding part 4 and the lever 3.

[0042] The lever 3 rotates to switch the locking and unlocking positions of the sliding part 4, while the sliding part 4 slides horizontally to limit the upper cover 1's limiting part 11. When the lever 3 rotates, the guide rod 41 moves flexibly within the range defined by the elongated slot 33, conforming to the rotation of the lever 3 while constraining the sliding part 4 to slide in a predetermined horizontal direction, ensuring that the two do not interfere with each other but work closely together. It should be noted that the sliding part 4 can be set as a solid block structure. In this case, the horizontal sliding part 4 needs to move to the lower end of the limiting part 11, that is, the sliding part 4 abuts against the lower end of the limiting part 11 to achieve the longitudinal connection between the upper cover 1 and the base 2; the sliding part 4 can also be set as a slider structure with a slot structure, i.e. Figure 6 The structure shown allows the sliding part 4 to enter the limiting part 11 during horizontal movement of the slot, and also enables longitudinal movement between the upper cover 1 and the base 2 (i.e., as shown). Figure 4 Connect in the direction shown in the diagram.

[0043] The rotation angle of the lever 3 precisely corresponds to the linear displacement of the guide rod 41 within the elongated slot 33, thereby accurately controlling the horizontal sliding distance of the sliding part 4. This ensures that each time the lever 3 switches positions, the sliding part 4 can precisely engage or disengage from the limiting part 11 of the upper cover 1, maintaining the accuracy of the pump upper cover installation and disassembly operations.

[0044] In some practical applications, refer to Figures 5 to 6 As shown, one end of the elongated slot 33 also has a clearance hole 34, allowing the limiting member 42 to pass through the clearance hole 34. The clearance hole 34 further improves the ease of assembly. During the initial assembly of this locking structure, the worker can easily pass the guide rod 41 and the limiting member 42 together through the clearance hole 34 and allow the guide rod 41 to slide into the elongated slot 33.

[0045] In some practical applications, refer to Figure 4 As shown, based on the aforementioned locking structure with mounting bracket 5, the upper cover 1 is also provided with a limiting groove 12. When the upper cover 1 is installed on the base 2, the mounting bracket 5 is at least partially embedded in the limiting groove on the upper cover 1 to achieve the limiting of the upper cover 1 in the horizontal direction of the base 2. That is, the mounting bracket not only serves as a structural component of the locking structure, but also has the function of pre-positioning the upper cover 1 to ensure the assembly position of the upper cover 1. The chamfered bevel design on the top of the left and right side walls of the mounting bracket 5 serves as a guide during the downward movement of the upper cover 1 onto the base 2.

[0046] In some practical applications, refer to Figure 4 As shown, the locking structure is configured in two sets, respectively located on two opposite sides of the base 2. Specifically, as shown in the figure, one locking structure is directly mounted on the base 2, and the other locking structure is mounted on the enclosure 22 of the base 2. The two locking structures can greatly increase the connection stability between the top cover 1 and the base 2. At the same time, the mounting bracket 5 on the other locking structure is higher than the mounting bracket 5 of the one locking structure, so the mounting bracket 5 on the other locking structure can also play a pre-positioning function for the entire top cover 1.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
