Description

Technical Field

[0001] This utility model belongs to the technical field of fly repellent equipment, and more specifically, it relates to a connecting plate for a fly repellent fan and a fly repellent fan. Background Technology

[0002] Fly repellent fans are primarily used to repel flies and are commonly found in places like delicatessens. A fly repellent fan mainly consists of a drive unit containing a motor. The motor's output shaft is connected to a support rod, on which a fly-repelling strip, made of materials such as cloth, is mounted. During operation, the motor drives the support rod to rotate, which in turn drives the fly-repelling strip, which repels flies as it rotates. Currently, in some fly repellent fan applications, the support rod is sometimes installed by directly inserting a plug into the socket on the motor's output shaft. While this method is simple, it is prone to instability, and the support rod may occasionally detach from the motor's output shaft during prolonged operation. Summary of the Invention

[0003] The purpose of this utility model is to provide a connecting plate for a fly-repelling fan and a fly-repelling fan, so as to overcome the problem of the support rod on the fly-repelling fan not being installed firmly in the prior art.

[0004] This utility model is achieved by the following technical solution: a connecting plate for a fly repellent fan, including a base, with snap-fit ​​structures provided on the front and rear sides of the bottom surface of the base; each of the snap-fit ​​structures on both sides includes two clamping arms spaced apart on the left and right, the clamping arms extending out of the bottom surface of the base, and the ends of the clamping arms bending towards the bottom surface of the base to form an arc segment, forming a snap-fit ​​between the arc segment and the bottom surface of the base, and forming an opening between the ends of the clamping arms and the bottom surface of the base, with the openings of the left and right clamping arms in one snap-fit ​​structure being arranged opposite to each other.

[0005] Furthermore, the snap-fit ​​structure also includes a limiting member, which includes a baffle installed on the bottom surface of the base; in the two-sided snap-fit ​​structure, the baffle in the one-sided snap-fit ​​structure is located on the outside of the left clamping arm, and the baffle in the other-sided snap-fit ​​structure is located on the outside of the right clamping arm.

[0006] Furthermore, the base bottom surface is provided with weight reduction holes on the lower side of the latch of each left clamping arm and the lower side of the latch of each right clamping arm.

[0007] Furthermore, the bottom surface of the base is provided with a slide rail on the side of each baffle near the clamping arm, and the slide rail is provided with an arc-shaped groove.

[0008] Furthermore, a brim is provided on the outer end face of the clamping arm near the baffle.

[0009] Furthermore, the base has mounting holes on its bottom surface, which are located between the front and rear snap-fit ​​structures. The base also has a transmission groove on its top surface, and the mounting holes are connected to the transmission groove.

[0010] Furthermore, the base has a top surface protrusion, and the transmission groove is formed on the end face of the top surface protrusion; the transmission groove has a polygonal structure; the base has a bottom surface protrusion, and the mounting hole is formed on the end face of the bottom surface protrusion; the mounting hole is a countersunk hole.

[0011] A fly-repellent fan includes a driving component, the driving component including a driving housing, and a motor installed inside the driving housing. The fan is characterized by further including a connecting plate for the fly-repellent fan, and the base is drively connected to the output shaft of the motor.

[0012] Furthermore, it also includes two support rods, each of which is installed on a snap-fit ​​structure. The support rods are snapped into the left and right snap-fit ​​slots of the snap-fit ​​structure near their ends. The ends of the support rods are provided with protrusions that protrude from the surface of the support rods. When the support rods are snapped into the left and right snap-fit ​​slots of the snap-fit ​​structure, the protrusions are outside the snap-fit ​​slots and protrude from the inner wall of the snap-fit ​​slots. A transmission head is provided at the bottom of the output shaft of the motor, and a threaded hole is provided on the end face of the transmission head.

[0013] Furthermore, a stop is provided on the surface of the support rod near its end; there are two stopes, and the two stopes are symmetrically arranged; fly-repelling strips are respectively installed at the beginning of the support rod on both sides; the support rod is a telescopic rod; the protrusion is rod-shaped or disc-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting a connecting plate for the fly-repelling fan, provides the following two advantages for the installation of the support rod:

[0016] 1. This utility model makes it easy to install the support rod by setting a connecting plate for the fly-repelling fan. When installing the support rod, simply place the support rod at an angle between the two clamping arms in a snap-fit ​​structure, and then push the support rod to rotate it from an inclined position to a horizontal position. During the rotation, the support rod will be inserted into the snap-fit ​​slots of the two clamping arms from the openings on both sides, thus completing the installation of the support rod.

[0017] 2. This utility model securely installs the support rod by setting a connecting plate for the fly-repellent fan, making it difficult for the support rod to detach from the connecting plate after installation. The clamping arm has a certain degree of elasticity, and the height of the opening is smaller than the outer diameter of the support rod near the end. At the same time, the inner diameter of the latch is also smaller than the outer diameter of the support rod near the end. Thus, when the support rod is inserted into the two latches in a snap-fit ​​structure, the inner walls of the two latches will tightly adhere to the support rod and clamp it, making it difficult for the support rod to detach from the latches on both sides. In addition, by setting a baffle and a protrusion at the end of the support rod, when the support rod is snapped into the latches on both sides, the protrusion will be between the baffle and the clamping arm, which can effectively restrict the lateral movement of the support rod. Furthermore, by setting two side blocks on the surface of the support rod near the end, the lateral movement of the support rod can be further restricted, preventing the support rod from moving laterally out of the latch.

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0030] A connecting plate for a fly repellent fan includes a base 1, with snap-fit ​​structures provided on the front and rear sides of the bottom surface of the base 1. When the base 1 is installed, the top surface of the base 1 faces the drive housing 14.

[0031] A fly repellent fan includes a driving component, which includes a driving housing 14. A motor is installed inside the driving housing 14. A transmission head 18 is provided at the bottom of the output shaft of the motor. A threaded hole is provided on the end face of the transmission head 18. The transmission head 18 can be inserted into the transmission groove 11 on the top surface of the base 1, and the shape of the transmission head 18 is the same as the shape of the transmission groove 11.

[0032] The base 1 has a mounting hole 10 on its bottom surface, which is located between the front and rear snap-fit ​​structures. The base 1 has a transmission groove 11 on its top surface, and the mounting hole 10 connects to the transmission groove 11. The base 1 also has a top surface protrusion 12 on its top surface, and the transmission groove 11 is located on the end face of the top surface protrusion 12. The transmission groove 11 has a polygonal structure, specifically a quadrilateral shape. The base 1 has a bottom surface protrusion 13 on its bottom surface, and the mounting hole 10 is located on the end face of the bottom surface protrusion 13. The mounting hole 10 is a countersunk hole.

[0033] When installing the base 1 of this utility model onto the motor output shaft, firstly, the top surface of the base 1 should face the motor output shaft. Then, the transmission head 18 of the output shaft is inserted into the transmission groove 11 on the base 1. Finally, screws or bolts are inserted into the mounting hole 10 and the threaded hole on the transmission head 18 and tightened. In this way, the base 1 is fixedly installed on the motor output shaft. Since both the transmission groove 11 and the transmission head 18 have a polygonal structure, the transmission head 18 will simultaneously drive the base 1 to rotate when it rotates.

[0034] Both sides of the snap-fit ​​structure include two clamping arms 2 spaced apart on the left and right. The clamping arms 2 extend out of the bottom surface of the base 1, and the ends of the clamping arms 2 bend toward the bottom surface of the base 1 to form an arc-shaped segment 3. The clamping arms 2 have a certain degree of elasticity.

[0035] A notch 4 is formed between the arc segment 3 and the bottom surface of the base 1, and an opening 5 is formed between the end of the clamping arm 2 and the bottom surface of the base 1. The openings 5 ​​of the left and right clamping arms 2 in a snap-fit ​​structure are arranged opposite to each other, that is, the bending directions of the ends of the two clamping arms 2 in a snap-fit ​​structure are opposite.

[0036] The snap-fit ​​structure also includes a limiting member, which includes a baffle 6 installed on the bottom surface of the base 1. The limiting member is used to limit the lateral displacement of the support rod 15. In application, the end of the support rod 15 is between the baffle 6 and the clamping arm 2, so that the baffle 6 can prevent the clamping arm 2 from moving in the direction of the baffle 6.

[0037] In the snap-fit ​​structures on both sides, the baffle 6 in one snap-fit ​​structure is located on the outside of the clamping arm 2 on its left side, and the baffle 6 in the other snap-fit ​​structure is located on the outside of the clamping arm 2 on its right side. With this arrangement, the extension directions of the support rods 15 installed on the two snap-fit ​​structures are opposite.

[0038] A fly-repellent fan further includes two support rods 15 on both sides. Each of the two sides has a snap-fit ​​structure with a support rod 15 installed on it. The support rods 15, near their ends, snap into the left and right snap-fit ​​slots 4 on either side of the snap-fit ​​structure. In this invention, the clamping arm 2 has a certain degree of elasticity, and the height of the opening 5 is smaller than the outer diameter of the support rod 15 near its end. Simultaneously, the inner diameter of the snap-fit ​​slot 4 is also smaller than the outer diameter of the support rod 15 near its end. Thus, when the support rod 15 is inserted into the two snap-fit ​​slots 4 of a snap-fit ​​structure, the inner walls of the two snap-fit ​​slots 4 will tightly adhere to the support rod 15, securing it and preventing the support rod 15 from easily detaching from the two snap-fit ​​slots 4.

[0039] The end of the support rod 15 is provided with a protrusion 16, which protrudes from the surface of the end of the support rod 15. When the support rod 15 is inserted into the left and right slots 4 in the snap-fit ​​structure, the protrusion 16 is outside the slot 4 and protrudes from the inner wall of the slot 4.

[0040] The protrusion 16 can be shaped like a disc or a plate-like structure of other shapes. For example, the protrusion 16 can also be designed as a polygonal plate-like structure. The dimensions of this plate-like structure must be such that it cannot pass through the slot 4 of the adjacent clamping arm. When the protrusion 16 is disc-shaped, the structure of the support rod 15 is as follows: Figure 9 As shown, when the support rod 15 of the disc-shaped protrusion 16 is installed onto the connecting plate for the fly-repelling fan, the installation structure is as follows: Figure 4-8As shown, the protrusion 16 is located between the baffle 6 and the clamping arm 2. The disc-shaped protrusion 16 prevents the support rod 15 from moving away from the baffle 6 by contacting the clamping arm 2. At the same time, when the support rod 15 moves towards the baffle 6, the baffle 6 will contact the protrusion 16 and prevent the support rod 15 from moving towards the baffle 6. Thus, the protrusion 16 and the baffle 6 work together to restrict the lateral movement of the support rod 15.

[0041] The protrusion 16 can also be rod-shaped, specifically cylindrical. When the protrusion 16 is designed as a rod-shaped structure, such as... Figure 10 As shown, a brim 19 needs to be provided on the outer end face of the clamping arm 2 near the baffle 6. The distance between the brim 19 and the corresponding baffle 6 should be less than the outer diameter of the rod-shaped protrusion 16. When installing the support rod 15, the rod-shaped protrusion 16 should be directly inserted between the brim 19 and the bottom surface of the base 1. This allows the rod-shaped protrusion 16 to be between the brim 19 and the bottom surface of the base 1, and between the clamping arm 2 and the baffle 6. The rod-shaped protrusion 16 prevents the support rod 15 from moving away from the baffle 6 by contacting the clamping arm 2. At the same time, after the support rod 15 is installed on both clamping arms 2, when the support rod 15 moves towards the baffle 6, the baffle 6 will contact the support rod 15 and prevent the support rod 15 from moving towards the baffle 6. Thus, the protrusion 16 and the baffle 6 together play the role of restricting the lateral movement of the support rod 15.

[0042] The support rod 15 has two side stops 17 on the surface near the end. The two side stops 17 are symmetrically arranged. When the support rod 15 is installed into the snap-fit ​​structure, the two side stops 17 are between the two side clamping arms 2. The two side stops 17 can further restrict the lateral movement of the support rod 15 and prevent the support rod 15 from moving laterally out of the two side clamping arms 2.

[0043] When installing the support rod 15 onto the base 1, the support rod 15 is first placed at an angle between the two clamping arms 2 in a snap-fit ​​structure. Then, the support rod 15 is pushed to rotate from an inclined position to a horizontal position. During the rotation, the support rod 15 will insert into the slots 4 of the two clamping arms 2 through the openings 5, thus completing the installation of the support rod 15. During the insertion of the support rod 15 into the opening 5, the arc-shaped segment 3 of the support rod 15 will undergo elastic deformation, thereby enlarging the opening 5. After the support rod 15 is installed on the base 1, the protrusion 16 will be between the baffle 6 and the clamping arms 2. The baffle 6 and the clamping arms 2 will prevent the protrusion 16 from moving laterally, thereby preventing the support rod 15 from moving laterally. At the same time, by providing two side stops 17 on the surface of the support rod 15 near the end, the rotation of the support rod 15 can be effectively restricted.

[0044] The base 1 has weight-reducing holes 7 on the underside of the latch 4 of each left clamping arm 2 and the underside of the latch 4 of each right clamping arm 2. The base 1 also has a slide rail 8 on the side of each baffle 6 near the clamping arm 2. The slide rail 8 has an arc-shaped groove 9, and the support rod 15 is located within the arc-shaped groove 9 of the slide rail 8. The latches 4 on both sides, the slide rail 8, and the baffle 6 in the snap-fit ​​structure together define a channel for accommodating and clamping the support rod 15.

[0045] A fly-repelling strip 20 is installed at the first end of the support rod 15. The support rod 15 is a telescopic rod. When the two support rods 15 rotate, they will drive the fly-repelling strip 20 at their respective ends to rotate. The fly-repelling strip 20 will have a good fly-repelling effect during rotation. The fly-repelling strip 20 can be made of materials such as cloth strips. This utility model uses a telescopic rod for the support rod 15, which can change the rotation radius of the fly-repelling strip 20 by extending and retracting the telescopic rod, thereby changing the fly-repelling radius.
