Technical Field

[0001] The utility model belongs to the technical field of pumps, and particularly relates to a fixing structure with an elastic buckle and a pump. Background Art

[0002] Currently, on water pumps, the box cover, box seat, heat insulation board, etc. are all plastic parts. For the fixation between plastic parts, screw locking or snap-in installation is mostly used. Between the box cover and box seat on the junction box, screw locking or snap-in installation is mostly used. However, the above screw locking or snap-in fixing methods have the problems of troublesome installation and disassembly, and low efficiency. When the pump is installed in a circulation system, if there is a fault and the box cover needs to be disassembled, due to the influence of the installation space of the pump, it is difficult to repair. At the same time, due to the above two connection methods, the structure is extremely easy to be damaged when disassembled repeatedly. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a fixing structure with an elastic buckle, so as to provide a connection structure for quick disassembly and save installation time.

[0004] Another purpose of the utility model is to provide a pump. The above fixing structure with an elastic buckle is applied to the pump, which is convenient for installation and fixation, and is also convenient for disassembly, avoiding damage to the structure of the pump when disassembled repeatedly.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fixing structure with an elastic buckle, comprising:

[0007] Buckle points and buckles symmetrically arranged on both sides of the buckle points. Each group of buckles includes a fixing part, an elastic part and a connecting part. The fixing part is fixed to the first structural member, the buckle point is fixed to the second structural member, and the first structural member can approach or move away from the second structural member;

[0008] One end of the elastic part is connected to the inner side of the fixing part, and the other end is connected to the connecting part. The buckle point can be clamped between the two connecting parts. Press the ends of the two connecting parts away from the buckle point, and the elastic part can be compressed and deformed by the connecting part, so that the openings at the other ends of the two connecting parts are opened to clamp or disconnect from the buckle point.

[0009] Preferably, the connecting part includes a clamping part and a supporting part. The clamping part is arranged inside the supporting part. The supporting part and the clamping part are arranged in an L shape. The elastic part is connected to the outside of the supporting part. The clamping part can be clamped or disconnected from the buckle point.

[0010] Preferably, the snap point is a regular tetrahedron, and the clamping portion is clamped with the snap point of the regular tetrahedron.

[0011] Preferably, the inner surface of the clamping portion contacts the bottom surface of the snap point.

[0012] Preferably, the supporting portion includes a first supporting portion and a second supporting portion connected to each other. One end of the first supporting portion is connected to the clamping portion. The included angle between the first supporting portion and the clamping portion is a first preset angle, and the first preset angle is greater than 90°. Two groups of the second supporting portions are arranged in parallel, and the elastic portion is connected to the outer wall of the first supporting portion.

[0013] Preferably, the travel of the two connecting portions in the width direction is not less than 2 mm.

[0014] Preferably, the elastic portion is wavy or spiral.

[0018] Compared with the prior art, the present utility model has the following beneficial effects: In the present utility model, the first structural member drives two groups of snaps to move towards the snap points on the second structural member, and the first structural member reaches a predetermined position. By pressing one end of the connecting portion away from the snap point by hand, the connecting portion relies on the deformation of the elastic portion, and the opening at one end of the connecting portion close to the snap point is opened, enabling the connecting portion to be clamped to the snap point, thereby realizing the connection between the two. When it is necessary to disconnect the connecting portion from the snap point, similarly press one end of the connecting portion away from the snap point, the opening at one end of the connecting portion close to the snap point is opened, and at the same time move the first structural member away from the second structural member to disconnect the connecting portion from the snap point.

[0029] As Figure 1 - Figure 2 shown, in this embodiment, a fixing structure with an elastic buckle is provided, which includes a buckle point 1 and buckles 2 symmetrically arranged on both sides of the buckle point 1. Each group of buckles 2 includes a fixing part 21, an elastic part 22 and a connecting part 23. The fixing part 21 is fixed to the first structural member, the buckle point 1 is fixed to the second structural member, and the first structural member can approach or move away from the second structural member;

[0030] One end of the elastic part 22 is connected to the inner side of the fixing part 21, and the other end is connected to the connecting part 23. The buckle point 1 can be clamped between the two connecting parts 23. By pressing the ends of the two connecting parts 23 away from the buckle point 1, the elastic part 22 can be compressed and deformed by the connecting parts 23, so that the openings at the other ends of the two connecting parts 23 are opened to clamp or disconnect the buckle point 1.

[0031] In this embodiment, the first structural member drives the two sets of buckles 2 to move towards the buckling points 1 on the second structural member, and the first structural member reaches a predetermined position. By manually pressing one end of the connecting portion 23 away from the buckling point 1, the connecting portion 23 relies on the deformation of the elastic portion 22, and the opening at one end of the connecting portion 23 close to the buckling point 1 is opened, enabling the connecting portion 23 to be snapped onto the buckling point 1, thereby achieving the connection between the two. When it is necessary to disconnect the connecting portion 23 from the buckling point 1, similarly press one end of the connecting portion 23 away from the buckling point 1, the opening at one end of the connecting portion 23 close to the buckling point 1 is opened, and at the same time move the first structural member away from the second structural member to disconnect the connecting portion 23 from the buckling point 1. In this embodiment, through the structural form of the two sets of buckles 2 and the buckling points 1, it is convenient for the two to be snapped or disconnected, so that the first structural member and the second structural member are convenient to open or close. The connection structure between the first structural member and the second structural member is a connection structure that can be quickly opened, and the first structural member and the second structural member will not be damaged due to multiple disassembly.

[0032] The above-mentioned buckling points in this embodiment are symmetric structures along their own central axes. Preferably, the buckling points are regular tetrahedron structures. Specifically, the buckling points are cubes or cuboids.

[0033] Preferably, the connecting portion 23 includes a clamping portion 231 and a supporting portion 232. The clamping portion 231 is arranged inside the supporting portion 232. The supporting portion 232 and the clamping portion 231 are arranged in an L shape. The elastic portion 22 is connected to the outside of the supporting portion 232. The clamping portion 231 can be snapped onto or opened from the buckling point 1. When the buckle 2 of the first structural member moves to the position of the buckling point 1, press one end of the supporting portion 232 away from the buckling point 1, and the clamping portions 231 at one ends of the two connecting portions 23 close to the buckling point 1 are opened and snapped onto the buckling point 1. This structure is convenient and fast to disassemble and will not damage the first structural member and the second structural member.

[0034] Preferably, the clamping portion 231 is snapped onto the regular tetrahedron-shaped buckling point 1. The buckling point 1 is set as a regular tetrahedron structure, which is simple in structure and easy to be snapped onto the buckle 2. After pressing the supporting portion 232 and the supporting portion 232 is opened, by using the position movement of the first structural member and the deformation of the elastic portion 22, the clamping portion 231 continues to move towards the buckling point 1. Release the supporting portion 232, and the clamping portion 231 is snapped onto the buckling point 1.

[0035] Preferably, the inner surface of the clamping portion 231 contacts the bottom surface of the buckling point 1. When the connecting portion 23 is connected to the buckling point 1, the buckling point 1 is located between the two connecting portions 23.

[0036] In other embodiments, a slot corresponding to the clamping portion 231 may be provided on the buckling point 1, and the end of the clamping portion 231 is clamped in the slot.

[0037] Preferably, the support portion 232 includes a first support portion 2321 and a second support portion 2322 that are connected to each other. One end of the first support portion 2321 is connected to the clamping portion 231. The angle between the first support portion 2321 and the clamping portion 231 is a first preset angle, and the first preset angle is greater than 90°. The two second support portions 2322 are arranged in parallel. The elastic portion 22 is connected to the outer wall of the first support portion 2321. The two second support portions 2322 being arranged in parallel facilitates manual pressing of the second support portion 2322. The angle between the first support portion 2321 and the clamping portion 231 is the first preset angle, and the first preset angle is greater than 90°. In this way, there is a spacing between the support portion 232 and the buckling point 1. When the second support portion 2322 is pressed, the two support portions 232 will move towards the side where the buckling point 1 is located, and the two first support portions 2321 will move away from the buckling point 1. The first preset angle being greater than 90° can reserve space for the movement of the support portion 232, thereby causing the two buckles 2 to open.

[0038] Preferably, the elastic portion 22 is connected to the lower end of the first support portion 2321 close to the clamping portion 231. The connection point between the elastic portion 22 and the first support portion 2321 serves as a fulcrum. The connection point between the elastic portion 22 and the second support portion 2322 is close to the lower end position of the second support portion 2322. When the second support portion 2322 is pressed, the stroke of the second support portion 2322 in the width direction is small, and the stroke of the first support portion 2321 in the width direction is large. Thus, it can be smoothly clamped with the buckling point 1.

[0039] Preferably, the strokes of the two connecting portions 23 in the width direction are both not less than 2 mm. The strokes of the two connecting portions 23 in the width direction are both at least 2 mm. To ensure that the size of the buckling point 1 is not less than 4 mm to guarantee the structural strength of the buckling point 1, the connection between the connecting portion 23 and the buckling point 1 is firm after clamping.

[0040] Preferably, the elastic portion 22 is wavy or spiral to improve the elasticity of the elastic portion 22 and extend its service life. Specifically, the elastic portion 22 is wavy.

[0041] In this embodiment, a pump is further provided, which includes the above-mentioned fixing structure with elastic buckles, a first structural member, and a second structural member. The fixing structure with elastic buckles is used to quickly fix or open the first structural member and the second structural member.

[0042] The above-mentioned pump can be a canned motor pump. The fixing structure with elastic buckles is applied to the junction box of pumps such as canned motor pumps. The first structural member is the junction box cover 10, and the buckle 2 is provided on the junction box cover 10. The second structural member is the junction box body 10, and the buckling point 1 is provided on the junction box body 10.

[0043] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
