The bottle opener is efficient and labor-saving, does not damage a bottle cap, and is simple in structure and durable.

Description

Technical Field

[0001] A daily necessity, in particular a bottle opener. Background Art

[0002] Corkscrews are centuries-old items, and their designs have evolved in a wide variety of forms. After a thorough search, I found that existing solutions can be primarily categorized into three types. The first is the "multi-hole-to-slot" type, exemplified by applications CN201210513267 and NL7607731. The drawback of this type is that the large area of contact between the bottle cap and the opener results in low contact pressure, leading to constant slippage. Furthermore, serrations on the inner surface of the bottle opener increase friction and easily damage the cap. The second type is the "sliding approach plus lever-twisting" type, exemplified by applications CN201521000266, CN201921790047, and CN202020674311. While this type is significantly more effective than the first, it also has drawbacks: it requires first sliding the chuck to initially contact the bottle cap, then pressing the lever handle to secure it, a somewhat cumbersome process. The third type is the "screw spinning type," as shown in application numbers CN201120298164, CN201821508175, and CN201820217301. The disadvantage of the third type is that it is inefficient. Adjusting the forward or backward movement of the chuck requires many turns of the screw, and it takes a long time to screw on a bottle cap.

[0003] Is there a bottle opener that saves effort, is efficient, and doesn't damage the bottle cap? There actually is one: the push-pull bottle opener I invented. Summary of the Invention

[0004] The push-pull type labor-saving and efficient bottle opener (hereinafter referred to as the "bottle opener") consists of two parts: an outward push hook and an inner pull hook. The outer push hook is located in the middle of an outward push tube, with an outward push frame welded vertically to the left and right ends of the tube, and an outward push head welded vertically downwards to the other end; the inner pull hook is located in the middle of an inner pull rod, with an inner pull frame welded vertically to the left and right ends of the tube, and an inner pull head welded vertically downwards to the other end; the inner pull rod is sleeved in the outer push tube and can slide along the outer push tube; the inner pull frame is located in the outer push frame, is in the same plane as the outer push frame, and can move in the inner space of the outer push frame; the inner pull head The outer push head is farther from the outer push frame than the inner pull head; there is also a first auxiliary frame at the right end of the outer push frame; the operator extends four fingers of one hand into the inner pull frame and the thumb into the first auxiliary frame, and extends or contracts the palm of the hand. The inner pull frame will change the distance between the inner pull head and the outer push head through the inner pull rod; if there is a bottle cap that needs to be tightened between the inner pull head and the outer push head at this time, just hold the four fingers and thumb together to make the inner pull head and the outer push head firmly clamp the bottle cap. At this time, continue to turn the bottle opener to loosen the bottle cap. The steps for tightening the bottle cap are similar to the above, only need to turn the bottle opener in the opposite direction in the last step. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0007] The bottle opener is described in detail below in conjunction with the accompanying drawings.

[0008] like Figure 5 and Figure 6The most basic bottle opener comprises two major components: an outward push hook (1) and an inner pull hook (2); the outward push hook (1) comprises an outward push frame (11), an outward push tube (12), an outward push head (13), and double push columns (14); one end of the outward push tube (12) is vertically fixedly connected to the middle of the left frame beam of the outward push frame (11), and the axis of the outward push tube (12) passes through the center of the outward push frame (11); the other end of the outward push tube (12) is vertically fixedly connected to an outward push head (13), and double push columns (14) are fixedly connected to the front and rear sides of the lower side of the outward push head (13). The axis of the double push column (14) is perpendicular to the upper and lower center planes of the push frame (11) and symmetrical about the front and rear center planes of the push frame (11); a central through hole (15) passes through the entire push head (13), the entire push tube 12, and the left frame beam of the push frame (11); the inner pull hook (2) includes an inner pull frame (21), an inner pull rod (22), an inner pull head (23), and a double pull column (24), one end of the inner pull rod (22) is vertically fixedly connected to the middle of the left frame beam of the inner pull frame (21), and the axis of the inner pull rod (22) passes through the inner pull frame (2 1) center; the other end of the inner pull rod (22) is vertically fixedly connected to an inner pull head (23), and the inner pull head (23) is fixedly connected to the double pull columns (24) on the front and rear sides below; the axis of the double pull columns (24) is perpendicular to the upper and lower center planes of the inner pull frame (21) and is symmetrical about the front and rear center planes of the inner pull frame (21); the inner pull rod (22) is sleeved in the middle through hole (15) of the outer push tube (12) and can slide left and right along the middle through hole (15), the inner pull frame (21) is located in the space surrounded by the frame beam of the outer push frame (11) and ... fixedly connected to the double pull columns (24); the axis of the double pull columns (24) is perpendicular to the upper and lower center planes of the inner pull frame (21) and is symmetrical about the front and rear center planes of the inner pull frame (21); the inner pull rod (22) is sleeved in the middle through hole (15) of the outer push tube (12) and can slide left and right along the middle through hole (15), the inner pull frame (21) is located in the space surrounded by the frame beam of the outer push frame (11) and the inner The upper and lower center planes of the pull frame (21) are coplanar with the upper and lower center planes of the outer push frame (11); the distance between the inner pull head (23) and the double pull pillars (24) and the outer push frame (11) is always greater than the distance between the outer push head (13) and the double push pillars (14) and the outer push frame (11); when the operator manually changes the position of the inner pull frame (21) in the outer push frame (11), the distance between the double pull pillars (24) and the double push pillars (14) also changes accordingly; the bottle cap to be unscrewed or opened is placed between the double push pillars (14) and the double pull pillars (24).

[0009] like Figure 7 In order to increase the friction between the double push pillars (14) and the double pull pillars (24) and the bottle cap to prevent slipping, some circular shallow push pillar anti-slip pits (17) are specially made on the surface of each double push pillar (14), and similar pull pillar anti-slip pits (27) are also made on the surface of each double pull pillar (24).

[0010] like Figure 8In order to increase the stability of the inner pull frame (21) and prevent the inner pull rod (22) from being bent by the forces in the up and down directions, a pair of guide slip rings (25) are specially welded to the front and rear frame beams of the inner pull frame (21).

[0011] like Figure 9 and Figure 10 Another measure to add restrictions to the inner pull frame (21) to prevent the inner pull rod (22) from being bent by the upward and downward forces is to weld two guide columns (26) to the outer sides of the front and rear frame beams of the inner pull frame (21), and at the same time cut two guide grooves (16) on the inner sides of the front and rear frame beams of the outer push frame (21), so that the guide columns (26) can slide left and right along the corresponding guide grooves (16).

[0012] like Figure 11 In order to increase the convenience of operating the bottle opener, a first auxiliary frame (18) is specially added to the extrapolation frame (11) to limit the range of movement of the thumb to prevent the bottle opener from falling out of the hand.

[0013] like Figure 12 In order to reduce excessive extension of fingers when screwing large bottle caps and excessive flexion of the palm when screwing small bottle caps, a second auxiliary frame (19) is specially added to the push-out frame (11); the second auxiliary frame (19) and the inner pull frame (21) can be used in combination when screwing large bottle caps, and the first auxiliary frame (18) and the inner pull frame (21) can be used in combination when screwing small bottle caps; Figure 11 The appearance of a bottle opener with the first auxiliary frame (18) and the second auxiliary frame (19) adopting a guide slip ring type stabilization measure is shown.

[0014] like Figure 13 The bottle opener having the first auxiliary frame (18) and the second auxiliary frame (19) can also adopt a guide groove type stabilization measure.

[0015] Beneficial effects Advantage 1: Effortless. The first reason for this is its strong grip. We know that the linear contraction grip of the human palm and fingers is incredibly strong. We often see that most people can easily hang themselves from a horizontal bar using only eight fingers on both hands, demonstrating that the contraction force of four fingers can reach at least half a person's body weight. Second, it provides a secure grip. The four pillars of the bottle opener's push and pull heads have a very small contact area with the bottle cap. The powerful force applied to such a small area creates a very high pressure. Combined with the anti-slip grooves on the four pillars, they provide a firm grip on the bottle cap. Third, the power arm is much longer than the resistance arm. The distance between the palm of your hand and the center of the bottle cap represents the power arm, while the resistance arm represents the radius of the bottle cap. The power arm is significantly larger than the resistance arm, which is why a bottle opener can be opened with just a slight twist. These features make this labor-saving bottle opener so easy to remove.

[0016] Advantage 2: Wide adaptability. Bottle caps as large as 8.5 cm in diameter (basically the largest bottle caps) and as small as 2.8 cm (mineral water, soda and beer bottle caps) can be unscrewed or opened in one go with this bottle opener.

[0017] Advantage 3: Easy to operate. It can be operated with one hand. Lift, aim, retract and twist with one hand, all in one go and extremely quickly.

[0018] Advantage 4: No damage to the bottle cap. The cylindrical bottle cap is sandwiched between four pillars, making it difficult to damage the bottle cap. We have seen that some slot-type bottle openers can easily damage bottle caps, especially metal ones.

[0019] Advantage 5: Simple structure and durability. This bottle opener has no fragile parts, nor is it subject to strong bending or twisting forces, making it resistant to damage. No parts or components are subject to significant friction, so it will show minimal wear and tear over years of use. Made of 304 or more corrosion-resistant stainless steel, this bottle opener will remain functional for decades.
