Description

Technical Field

[0001] This application relates to the field of pressing technology, and in particular to a pressing device with high safety performance. Background Technology

[0002] Electric household garden sprayers have become increasingly popular in recent years. They feature a built-in lithium battery and a miniature diaphragm pump, automatically generating pressure when a switch is pressed, allowing the liquid inside the sprayer to continuously spray from the nozzle. The nozzle contains a spray tip that atomizes the liquid as it is sprayed out in a cone shape.

[0003] To achieve lightweight design and reduce manufacturing costs for household sprayers, nozzles and spray heads are typically made of plastic. The plastic nozzles and spray heads are then pressed together using a press to form a connection between them.

[0004] However, the pressing machines currently used for nozzles and spray nozzles lack protective structures. During the pressing process, the nozzles may deform under high pressure, or even detach from the pressing equipment and be thrown outward after severe deformation, which is not conducive to safe pressing operations.

[0005] Therefore, it is necessary to develop a high-safety-performance pressing device to improve the safety of the pressing process, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0006] This application provides a high-safety-performance pressing device, which aims to solve the problem that the pressing machines currently used for nozzles and spray nozzles lack protective structures. During the pressing process, the nozzle may deform under high pressure, or even detach from the pressing device and be thrown outward after severe deformation, which is not conducive to safe pressing operations.

[0007] To achieve the above objectives, this application proposes a high-safety-performance pressing device, including a base, a support frame on the base, a pressure rod movably mounted on the support frame, a pressure head at the bottom end of the pressure rod, and a nozzle connected to the pressure head. The device also includes: a mounting plate mounted on the base; and a pressing sleeve mounted on the mounting plate, with a receiving hole inside the pressing sleeve, into which the nozzle is placed.

[0008] In some embodiments, it further includes: a tapered protrusion, wherein the bottom end of the pressure head is provided with a tapered protrusion, and the nozzle is provided with a tapered hole adapted to the tapered protrusion.

[0009] In some embodiments, the system further includes: a guide seat, which is mounted on the support frame, the guide seat having a guide hole adapted to the pressure rod, and the pressure rod being movably disposed in the guide hole.

[0010] In some embodiments, the system further includes: a first connecting rod, one end of which is rotatably connected to a guide seat; a second connecting rod, one end of which is provided with a first rotating shaft, the first rotating shaft being rotatably connected to the other end of the first connecting rod, and the other end of the second connecting rod being rotatably connected to a pressure rod; and a drive lever connected to the first rotating shaft.

[0011] In some embodiments, the device further includes: a first connector, which is disposed on the guide seat; a second connector, which is disposed on the pressure rod; and an elastic element, which is disposed between the first connector and the second connector.

[0012] In some embodiments, it further includes: an abutment portion, which is mounted on the support frame and contacts the guide seat.

[0013] This application proposes a high-safety-performance pressing device, including a base, a support frame mounted on the base, a pressure rod movably mounted on the support frame, a pressure head at the bottom of the pressure rod, and a nozzle connected to the pressure head. The device also includes: a mounting plate mounted on the base; and a pressing sleeve mounted on the mounting plate, containing a receiving hole into which the nozzle is placed. During the pressing process, the nozzle is inserted into the receiving hole of the pressing sleeve. At this time, the pressure rod drives the pressure head downwards, forcing the nozzle's connecting part into the nozzle's connecting sleeve, thus connecting the nozzle and the nozzle head. The entire pressing process takes place within the receiving hole, which effectively limits nozzle deformation and improves the safety of the entire pressing process. Attached Figure Description

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0017] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this application proposes a high-safety-performance pressing device, including a base 1, a support frame 11 on the base 1, a pressure rod 5 movably mounted on the support frame 11, a pressure head 4 at the bottom end of the pressure rod 5, the pressure head 4 being connected to a nozzle 13, and also including: a mounting plate 2, the mounting plate 2 being mounted on the base 1; and a pressing sleeve 3, the pressing sleeve 3 being mounted on the mounting plate 2, the pressing sleeve 3 having a receiving hole inside, and the nozzle 9 being placed inside the receiving hole.

[0018] The base 1 serves as the structural foundation of the pressing equipment, and all other structures on the pressing equipment are directly or indirectly mounted on the base 1. The base 1 also has threaded holes, through which it is connected to external structures using screws to ensure its stability. The support frame 11 forms the basis for structures such as the pressure rod 5. Preferably, the support frame 11 includes side plates on both sides, a front connecting plate, and a rear connecting plate. The side plates on both sides are connected to the front and rear connecting plates using screws, and the side plates on both sides, the front connecting plate, and the rear connecting plate are all connected to the base 1 using screws.

[0019] A transition piece is provided between the pressure rod 5 and the pressure head 4. The transition piece is connected to the bottom of the pressure rod 5 by screws. The bottom of the transition piece is provided with a threaded hole for the pressure head 4 to connect to. The pressure head 4 is screwed to the bottom end of the transition piece. The nozzle 9 has a connecting cylinder 18 inside. The outer circumferential surface of the connecting cylinder 18 is provided with a connecting wing 8. The connecting wing 8 is connected to the inner side of the nozzle 9. The nozzle 9, the connecting cylinder 18, and the connecting wing 8 are integrally formed. The nozzle 13 includes a connecting part 132 that adapts to the connecting cylinder 18 and a guide part 131. The connecting part 132 and the connecting cylinder 18 are interference fit H7 / p6. After the nozzle 13 is connected, the nozzle 9 is installed at the end of the pipe. The liquid flow inside the pipe is sprayed out from the nozzle. During the spraying process, the guide part 131 guides the liquid flow, making the liquid flow sprayed from the nozzle conical. Along the liquid flow direction, the gap between the guide part 131 and the inner wall of the nozzle 9 becomes smaller and smaller, resulting in the liquid flow pressure becoming larger and larger, and atomizing when sprayed.

[0020] In this embodiment, both nozzle 13 and spray head 9 are made of POM (polyoxymethylene) material, which has excellent mechanical properties and wear resistance. It can withstand frequent friction and the erosion of particulate matter, which helps nozzle 13 and spray head 9 adapt to harsh operating environments.

[0021] The pressing sleeve 3 is the core structure of the pressing equipment. The pressing sleeve 3 has a receiving hole with a diameter equal to the outer diameter of the nozzle 9, and the depth of the receiving hole is equal to the height of the nozzle 9. The pressing action of the nozzle 13 is completed within the receiving hole.

[0022] In this embodiment, the outer diameter of the bottom end of the pressure head 4 is larger than the outer diameter of the receiving hole. When the pressure head 4 comes into contact with the pressing sleeve 3, it is determined that the nozzle 13 has been pressed into place.

[0023] Specifically, during the pressing process, the nozzle 9 is placed into the receiving hole of the pressing sleeve 3. At this time, the pressure rod 5 drives the pressure head 4 to press down, and the pressure head 4 forces the connecting part 132 of the nozzle 13 into the connecting sleeve 18 of the nozzle 9, thus realizing the connection between the nozzle 13 and the nozzle 9. The entire pressing process is carried out within the receiving hole, which can effectively limit the deformation of the nozzle 9 and improve the safety of the entire pressing process.

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, it further includes a conical protrusion, with the bottom end of the pressure head 4 having a conical protrusion and the nozzle 13 having a conical hole adapted to the conical protrusion. The conical protrusion and the conical hole on the nozzle 13 can effectively ensure the coaxiality between the pressure head 4 and the nozzle 13, improving the pressing effect.

[0025] In this embodiment, the nozzle 13 is preferably attached to the pressure head 4 with an adhesive, that is, the outer side of the conical protrusion is coated with an adhesive, and the type of adhesive is Blu-Tack. During the process of lifting the pressure rod 5 after pressing is completed, the formed nozzle 9 and nozzle 13 can be carried out by the pressure head 4, avoiding the need to pry the nozzle 9 out of the receiving hole, thus improving processing efficiency.

[0026] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, it further includes: a guide seat 6, which is mounted on the support frame 11. The guide seat 6 is provided with a guide hole adapted to the pressure rod 5, and the pressure rod 5 is movably disposed in the guide hole. The guide seat 6 is connected to the front connecting plate by screws. Through the cooperation between the guide hole in the guide seat 6 and the pressure rod 5, the stability and directional accuracy of the pressure rod 5 during the pressing process are improved.

[0027] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, it further includes: a first connecting rod 15, one end of which is rotatably connected to a guide seat 6; a second rotating shaft is provided at one end of the first connecting rod 15, and a rotating shaft hole adapted to the second rotating shaft is provided on the guide seat 6 to form a rotatable connection between the guide seat 6 and the first connecting rod 15. Both ends of the second rotating shaft are provided with slots, and C-shaped clamps are engaged in the slots to abut against the guide seat 6 and prevent axial displacement of the second rotating shaft. A second connecting rod 14, one end of which is provided with a first rotating shaft, rotatably connected to the other end of the first connecting rod 15; the other end of the second connecting rod 14 is rotatably connected to a pressure rod 5; a third rotating shaft is provided at the other end of the second connecting rod 14, and a rotating shaft hole adapted to the third rotating shaft is provided on the pressure rod 5. Both ends of the third rotating shaft are provided with slots, and C-shaped clamps are engaged in the slots to abut against the pressure rod 5 and prevent axial displacement of the second rotating shaft. A drive lever 7 is connected to the first rotating shaft. A locking nut is screwed to one end of the first rotating shaft. The locking nut and the drive lever 7 abut against both sides of the first connecting rod 15 to prevent axial displacement of the first rotating shaft. By pressing down or raising the drive lever 7, the pressure rod 5 can be driven down or up to complete the pressing action. The entire process is manually driven, which saves costs and reduces the possibility of accidents during the pressing process.

[0028] See Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, it further includes: a first connector 16, which is provided on the guide seat 6; the first connector 16 is preferably a screw, and is screwed onto the support frame 11; a second connector 17, which is provided on the pressure rod 5; the second connector 17 is preferably a screw, and is screwed onto the pressure rod 5. An elastic element 10 is provided between the first connector 16 and the second connector 17. The elastic element 10 is a spring, and both ends of the elastic element 10 are provided with connecting hooks. The connecting hook at one end of the elastic element 10 connects to the first connector 16, and the connecting hook at the other end of the elastic element 10 connects to the second connector 17. By providing the elastic element 10, the pressure head 4 is positioned above the pressure sleeve 3 in its natural state, and is installed with the nozzle 13 and the spray head 9.

[0029] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, it further includes an abutment portion 12, which is mounted on the support frame 11 and contacts the guide seat 6. The abutment portion 12 is connected to the front connecting plate and the side plate by screws, and is used to support the guide seat 6 to further improve the stability of the guide seat 6.
