Description

Technical Field

[0001] This utility model relates to a pressing device, and more particularly to a pressing device that can slow down the ejection speed. Background Technology

[0002] A pressing device (or spring presser), such as the "press-rebound device and cabinet using the pressing-rebound device" in Chinese patent CN210396449U, includes a base, a compression spring, a telescopic rod, and a housing. One end of the compression spring abuts against the base, and the other end of the compression spring abuts against the telescopic rod. The telescopic rod is slidably connected to the housing. At least one slider is provided on the telescopic rod, and the housing is provided with a slide rail and a limiting groove corresponding to the slider. The slide rail is used for the slider to slide, and the limiting groove is used to restrict the slider to slide. When the compression spring is pressed or released, the slider selectively enters the slide rail or the limiting groove.

[0003] However, in the current environment, door poppers are all "hard pops," meaning they forcefully and rapidly eject the door. When the door panel is pressed, the spring in the popper generates elasticity, causing the door panel to pop out quickly. If a child accidentally touches the door panel, they could be hit by the ejected panel and injured. On the other hand, if the door is closed even slightly forcefully, the door panel may pop out, making it impossible to close and producing a loud noise.

[0004] Therefore, how to improve upon the aforementioned deficiencies is the technical challenge that the inventor of this utility model intends to solve. Utility Model Content

[0005] In view of the prior art, the present invention aims to solve and improve the problems and deficiencies existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a pressing device, comprising: a hollow tube with a hook seat at one end and a hook portion thereon; a mechanism disposed inside the tube, the mechanism having a groove having a first end and a second end, the outer diameter of the first end gradually increasing towards the second end, and a slot and a rod respectively at each end of the mechanism, the hook portion of the hook seat being able to engage or disengage from the slot of the mechanism; a rubber sleeve disposed in the groove, the rubber sleeve being movable along the groove, the rubber sleeve having an annular portion; and an elastic member disposed between the hook seat and the mechanism, the elastic member being connected to both the hook seat and the mechanism.

[0007] The annular part is a rubber ring or a sealing ring.

[0008] The annular portion is composed of multiple annularly arranged recesses.

[0009] It also includes a fixed base plate, which is located at one end of the rod and has an elastic part.

[0010] The hook is fixed to one end of the tube body by a pin.

[0011] The elastic element is a spring.

[0012] The hook seat is equipped with a ventilation slot.

[0013] The beneficial effects of this invention are as follows: the rubber sleeve can move along the groove and gradually expands during movement. The expanded rubber sleeve generates friction with the inner wall of the tube, and this friction creates resistance to the movement of the mechanism, effectively reducing the speed at which the mechanism is ejected by the elastic element. This prevents the rod connected to the mechanism from quickly ejecting the door panel, thus avoiding safety hazards. Furthermore, the rubber sleeve has an annular portion to increase the contact area with the inner wall of the tube, thereby enhancing friction and damping effects. Attached Figure Description

[0036] To facilitate a clearer understanding of the other features, advantages, and effects of this utility model, the following detailed description, in conjunction with the accompanying drawings, is provided:

[0037] Please see Figure 1 and Figure 2 As shown, this utility model provides a pressing device, comprising:

[0038] A hollow tube 1 has a hook seat 11 at one end inside the tube 1, and the hook seat 11 has a hook part 12. The hook seat 11 can be fixed to the inner end of the tube 1 by a pin 13 to ensure a stable installation.

[0039] More specifically, one end of the tube body 1 is provided with a hook base pressing block 14, and the hook portion 12 is located between the hook base 11 and the hook base pressing block 14. The hook base pressing block 14 passes through a fixing hole 15 of the hook base 11, thereby firmly fixing the hook portion 12 to the hook base 11. In addition, a portion of the hook base 11 is inserted into the interior of the tube body 1, so that the hook portion 12 is located at one end inside the tube body 1. The pin 13 passes through a first pin hole 16 of the tube body 1 and a second pin hole 17 of the hook base 11 to further fix the hook base 11. The hook portion 12 can adopt a C-shaped hook design, and the hook base 11 can be provided with a vent groove 18 to provide better functionality.

[0040] A movement 2 is disposed inside the tube body 1. The movement 2 has a groove 21, which has a first end 211 and a second end 212 (shown in the figure). Figure 4 The outer diameter of the first end 211 gradually increases towards the outer diameter of the second end 212 (illustrated in...). Figure 4 The mechanism 2 has a slot 22 and a rod 23 at each end. The hook 12 of the hook seat 11 can engage or disengage from the slot 22 of the mechanism 2. The rod 23 may have an internal thread, and the mechanism 2 may have an external thread. The internal and external threads are connected to form a whole.

[0041] A rubber sleeve 3 is disposed in the groove 21 and is movable along the groove 21. The rubber sleeve 3 has an annular portion 31. The annular portion 31 refers to a structure that is ring-shaped around the central axis along the surface of the rubber sleeve 3. The rubber sleeve 3 can be coated with lubricating oil.

[0042] The function of the rubber sleeve 3 is to slow down the ejection speed of the elastic element 4 onto the mechanism 2 when it contacts the inner wall of the tube body 1, thereby achieving a smoother damping effect. The annular portion 31 can increase the contact range with the inner wall of the tube body 1, while improving friction and damping effect. The annular portion 31 of the rubber sleeve 3 can be selectively replaced by other structures with similar effects. The annular portion 31 can be a rubber ring or a sealing ring, or the annular portion 31 can be composed of multiple annularly arranged recesses (illustrated in...). Figure 10 Alternatively, the annular portion 31 may be made of a material with a high coefficient of friction (such as silicone, polyurethane, rubber, etc.).

[0043] The recesses in the annular portion 31 can deform or compress under stress, thereby absorbing some of the impact force. In addition, the design of these recesses can distribute external forces to multiple contact points, avoiding pressure concentration in a single area, thereby reducing the risk of localized deformation or damage to the rubber sleeve 3.

[0044] The following comparison focuses on the form of the annular portion as a rubber ring (or sealing ring) versus the recessed portion, allowing you to choose according to your actual needs:

[0045]

[0046]

[0047] An elastic element 4 is disposed between the hook seat 11 and the mechanism 2, and is connected to both the hook seat 11 and the mechanism 2. The elastic element 4 may be a spring, which generates an elastic force to eject the mechanism 2, thereby causing the rod 23 connected to the mechanism 2 to eject.

[0048] The pressing device also includes a fixed base plate 5, which is located at one end of the rod 23, and the fixed base plate 5 is provided with an elastic part 51.

[0049] When the pressing device of this utility model is assembled, the hook seat 11 and the tube body 1 are tightly fitted. Tight fit (interference fit) means that when two parts are assembled, the fit between the two parts is very tight (with a small gap or even no gap), and external force is usually required for assembly.

[0050] Please see Figure 2 and Figure 3 As shown, this utility model can be applied to door structures, including a door frame 7 and a door panel 8. The tube 1 is installed on the door frame 7, and the fixing plate 5 can be glued to the door panel 8 with double-sided adhesive. The elastic part 51 of the fixing plate 5 is inserted into the rod 23, so that the door panel 8 presses against the fixing plate 5, thereby putting the door in a closed state. In this state, the hook 12 engages with the slot 22 of the mechanism 2, so that the elastic element 4 located between the hook seat 11 and the mechanism 2 is compressed, generating elastic force. At the same time, the rubber sleeve 3 is located at the first end 211 of the groove 21 (e.g., Figure 4 (As shown). Because the diameter of the mechanism 2 is smaller at the first end 211 of the groove 21, the size of the rubber sleeve 3 is also reduced, resulting in a gap between it and the inner wall of the tube 1, allowing internal air to escape. This design ensures that no additional force is required when pressing the door panel 8, thereby improving ease of use and smoothness.

[0051] Please see Figure 5 and Figure 6 When the door panel 8 is pressed, the door panel 8 presses against the fixed seat plate 5, causing the elastic part 51 of the fixed seat plate 5 to contact the rod 23 inside the tube body 1 (e.g., Figure 2 As shown), this causes the rod 23 to move slightly. With the movement of the rod 23, the mechanism 2 also moves slightly, causing the hook 12 to separate from the slot 22 of the mechanism 2 (as shown). Figure 7 As shown), the elastic element 4 is released. Figure 2 ) elasticity.

[0052] When the elastic element 4 releases its elastic force, the mechanism 2 pops out rapidly, and instantly, the rubber sleeve 3 and the tube body 1 (shown in the diagram)... Figure 2 Friction is generated on the inner wall, causing the rubber sleeve 3 to move from the first end 211 of the groove 21 (e.g., Figure 4 (As shown) moves to the second end 212. At the second end 212 of the groove 21 (as shown) Figure 8As shown), the rubber sleeve 3 is stretched, further increasing the friction with the inner wall of the tube 1. This friction creates resistance to the movement of the mechanism 2, controlling its ejection process and preventing it from ejecting too quickly. Finally, the mechanism 2 ejects rapidly, driving the rod 23 to push the fixed base plate 5, thereby causing the door panel 8 to eject (as shown). Figure 9 (As shown).

[0053] Furthermore, because the hook 11 fits tightly with the tube 1, and the expanded rubber sleeve 3 is also in close contact with the inner wall of the tube 1, a sealed environment is formed inside the tube 1, resulting in a decrease in internal pressure and creating a near-vacuum state. Due to the pressure difference between the inside and outside, the high external pressure exerts pressure on the low internal pressure environment, generating suction. This suction further slows down the ejection speed of the mechanism 2, causing the rod 23 to extend slowly.

[0054] However, to prevent the movement 2 from being excessively obstructed, the hook 11 is provided with a venting groove 18 (such as...). Figure 2 As shown), the ventilation slot 18 (as shown) Figure 2 As shown, air is allowed to slowly enter the tube 1, gradually releasing the vacuum state and ensuring that the elastic force of the elastic element 4 can smoothly push the mechanism 2 out, thereby causing the rod 23 connected to the mechanism 2 to slowly extend, and finally push the door panel 8 to pop open, so that the door is in the open state.

[0055] This invention utilizes the gradual increase in outer diameter from the first end 211 to the second end 212 of the groove 21. This ensures that the rubber sleeve 3 is gradually compressed under pressure, forming a tighter seal. Especially in applications requiring vacuum or high-pressure sealing, this gradual compression reduces the risk of leakage and ensures that pressure is evenly distributed across the surface of the rubber sleeve 3, preventing localized stress concentration that could lead to failure or deformation, thus extending the lifespan of the rubber sleeve 3. Furthermore, as the rubber sleeve 3 moves along the groove 21, it expands, generating friction between the expanded rubber sleeve 3 and the inner wall of the tube 1. This friction resists the movement of the mechanism 2, reducing the speed at which the mechanism 2 and the rod 23 are ejected by the elastic element 4, preventing the rod 23 from rapidly ejecting from the door panel 8 and causing danger. Additionally, the rubber sleeve 3 has an annular portion 31 to increase the contact area with the inner wall of the tube 1, enhancing friction and damping effects. In addition, the elastic part 51 of the fixed seat plate 5 is elastic, which can provide a silent effect and shock absorption effect, making it quieter for users when closing the door, and also greatly extending its service life.

[0056] The above discussion is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, any equivalent changes in shape, structure or combination made without departing from the spirit and scope of the present utility model should be covered within the scope of the patent application of the present utility model.
