Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to an orthogonal pressurized chamber structure and a toy gun. Background Technology

[0002] Toy guns are a popular type of toy in the toy industry. With continuous technological advancements, children's demands for toy guns are constantly increasing. The chamber of existing toy guns on the market typically consists of a main cavity, an adjustment knob, a pressure arm, and a pressure element. Pressure is applied to a flexible roller via a mechanical arm, and this pressure is transmitted through the pressing surface of the pressure element to the upper rubber tube, causing the bullet inside the upper rubber tube to rotate. The pressure pad often takes the form of a roller, which provides point pressure on a surface tangential to the upper rubber tube and transmits pressure in a circular / angular motion. Because of the roller's circular motion, the pressure contact point continuously moves, which is not conducive to applying pressure to the bullet's rotation and reduces shooting accuracy. Utility Model Content

[0003] In view of this, the present invention provides an orthogonal pressurized chamber structure and a toy gun, which aims to solve or at least improve the above-mentioned problems to a certain extent.

[0004] To solve the above problems, this utility model adopts the following technical solution: an orthogonal pressurized chamber structure, comprising: a shell; a drive element detachably connected to the shell; a rocker arm movably connected to the shell; and a pressure pad assembled inside the shell. The shell also provides a transmission element that abuts against the rocker arm and the pressure pad respectively. The first and second axial ends of the rocker arm abut against the drive element and the transmission element respectively. The pressure pad is shape-fitted to the transmission element, and the end face of the pressure pad facing away from the transmission element is a planar structure. The drive element drives the pressure pad to move through the rocker arm and the transmission element.

[0005] In some embodiments, the pressure pad includes a first part and a second part connected together, the transmission element has a cavity, the first part engages with the cavity, and the first part is used to abut against the upper-spinning rubber tube.

[0006] In some embodiments, in the axial direction, the side length of the second portion that connects to the first portion is greater than the side length of the first portion, but less than the length of the transmission element.

[0007] In some embodiments, the housing includes a first housing and a second housing connected vertically, with a through hole formed between the first housing and the second housing, the rocker arm hinged to the first housing, the transmission element located in the area below the second end of the rocker arm, and the pressure pad located at the through hole.

[0008] In some embodiments, the first housing includes two spaced-apart side plates and a pin, the pin passing sequentially through one side plate, the middle of the rocker arm, and the other side plate, thereby hinged the rocker arm to the first housing.

[0009] In some embodiments, the second housing has an axially opposite input end and an output end, the output end being axially open for the projectile to be ejected, the driving element being an adjustment disc rotatably sleeved on the input end of the housing, the end face of the adjustment disc facing the output end having an involute spiral groove, and the first end of the rocker arm engaging with the spiral groove.

[0010] In some embodiments, the end face of the adjustment disk facing the output end is provided with anti-loosening ratchet teeth, the input end is fitted with a pressure ring that acts on the convex part, and the pressure ring is positioned closer to the input end relative to the adjustment disk.

[0011] In some embodiments, the anti-loosening ratchet is closer to the rotation center of the adjusting disc than the spiral groove.

[0012] In some embodiments, the outer peripheral surface of the adjustment disc is provided with anti-slip texture, and its annular surface facing the input end is provided with gear scale.

[0013] This application also provides a toy gun, including the orthogonal pressurized chamber structure described in any of the preceding claims.

[0014] Compared to the traditional chamber structure, which consists only of the chamber body, adjustment knob, pressure arm, and roller-type pressure element, this application employs a more sophisticated component configuration: including a housing, a rocker arm disposed within the housing, a pressure pad, and transmission elements that respectively abut against the rocker arm and the pressure pad. By connecting the pressure pad with the transmission element in a shape-fitting manner, and constructing the end face of the pressure pad facing away from the transmission element as a planar structure, the contact area is increased to disperse pressure, effectively avoiding the energy loss problem caused by point pressure concentration in traditional designs.

[0015] Compared with existing technologies, this application, through its innovative orthogonal pressure adjustment structure design, ensures the stability of the projectile components while maximizing the contact area between the projectile and the retaining ring, thereby making more efficient use of the Magnus effect. This technological advantage directly translates into improved shooting accuracy, extended effective range, and significantly improved ballistic consistency. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0028] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0029] This utility model discloses a toy gun (not shown), such as Figures 1 to 3 As shown, it includes an orthogonal pressurized chamber structure 100. The orthogonal pressurized chamber structure 100 of this embodiment includes a housing 10, a drive element 20 detachably connected to the housing 10, a rocker arm 30 movably connected to the housing 10, a pressure pad 50 assembled within the housing 10, and a transmission element 40. The transmission element 40 abuts against the rocker arm 30 and the pressure pad 50 respectively. The first axial end 31 and the second axial end 32 of the rocker arm 30 abut against the drive element 20 and the transmission element 40 respectively. Here, axial direction refers to the direction of projectile launch. The pressure pad 50 forms a form-fit connection with the transmission element 40, and the end face 521 of the pressure pad 50 facing away from the transmission element 40 is a planar structure. The drive element 20 drives the pressure pad 50 to move through the rocker arm 30 and the transmission element 40. This embodiment, through an optimized pressure adjustment structure, can significantly improve the shooting accuracy of the toy gun.

[0030] Specifically, the shell 10 can be injection molded from a polymer material and includes a first shell 11 and a second shell 12 that are interconnected. The first shell 11 is disposed on the upper part of the second shell 12, and a through hole 13 is formed between the first shell 11 and the second shell 12.

[0031] The upper housing 11 includes a pin 112 and two parallel, spaced-apart mounting plates 111 extending axially. A mounting space is formed between the two mounting plates 111 to accommodate the pin 112 and the rocker arm 30. The pin 112 passes sequentially through one mounting plate 111, the middle of the rocker arm 30, and the other mounting plate 111, thereby hinged the rocker arm 30 to the first housing 11. Preferably, the pin 112 may be made of aluminum.

[0032] Combination Figure 3 and Figure 6 As shown, the rocker arm 30 is longitudinally elongated and can be injection molded from a polymer material. Its extension direction is consistent with that of the mounting plate 111. The rocker arm 30 includes a first end 31 and a second end 32 in the axial direction, with a pin hole 33 between them for the pin shaft 112 to pass through, thus constructing the rocker arm 30 as a lever structure. The first end 31 of the rocker arm 30 is used to cooperate with the drive element 20. The first end 31 protrudes from the first housing 11. The second end 32 of the rocker arm 30 is used to dynamically abut against the transmission element 40. When the drive element 20 applies a driving force to the first end 31 of the rocker arm 30, the rocker arm 30 rotates around the pin shaft 112, causing the second end 32 to output a linear force to the transmission element 40.

[0033] The transmission element 40 is block-shaped and can be injection molded from a polymer material. It is located between the two mounting plates and below the second end 32 of the rocker arm 30. The transmission element 40 is used to transmit the power from the second end 32 of the rocker arm 30 to the pressure pad 50. It should be noted that the orientation in this specification is based on the conventional holding orientation of a toy gun. The transmission element 40 has a recess 41 facing away from the second end 32 (i.e., downward direction) for engaging with the pressure pad 50. Preferably, the contact surface between the second end 32 and the transmission element 40 is planar. Correspondingly, the contact surface between the transmission element 40 and the second end 32 of the rocker arm 30 is also planar, thereby ensuring stable pressure transmission.

[0034] The pressure pad 50 is also block-shaped and is located below the transmission element 40 at the through hole 13 between the first housing 11 and the second housing 12. The pressure pad 50 includes a first portion 51 and a second portion 52 connected together, wherein the first portion 51 is semi-cylindrical and the second portion 52 is cuboid. The end face 521 of the pressure pad 50, which is opposite to the transmission element 40 and is configured as a planar structure, is located on the second portion and is used to apply pressure to the spiral rubber tube inside the second housing 12. Preferably, the pressure pad 50 is made of an elastic material. The first portion 51 of the pressure pad 50 engages with the cavity 41 of the transmission element 40. It is understood that the cavity 41 of the transmission element 40 is configured to fit the semi-cylindrical portion to form a torsion-resistant engagement between the transmission element 40 and the pressure pad 50. More preferably, in the axial direction, the side length of the second portion 52 that engages with the first portion 51 is greater than the diameter of the first portion 51 and less than the length of the transmission element 40. This allows the first part 51 of the pressure pad 50 to fully engage with the cavity 41 of the transmission element 40, without causing the second part 52, which contacts the upper-spinning rubber tube, to deform.

[0035] Since the pressure pad 50 of the orthogonal pressurized chamber structure 100 of this application is shaped and connected to the transmission element 40, and the end face 521 of the pressure pad 50 facing away from the transmission element 40 is planar, the pressure is dispersed by increasing the contact area, which effectively avoids the energy loss problem caused by the pressure concentration of the pressure pad in the traditional design.

[0036] The second housing 12 is located below the first housing 11 and is longer than the first housing 11. The second housing 12 also extends axially and includes an input end 121 and an output end 122 that are axially opposite each other. An axially extending projectile channel is provided inside the second housing 12, which communicates with the first housing 11, and an upward-spinning rubber tube can be installed within it. The output end 122 is axially open for projectile ejection. A pressure pad 50 is located above the upward-spinning rubber tube, and the end face 521 of the cuboid portion of the pressure pad 50 abuts against the upward-spinning rubber tube. When the projectile enters the upward-spinning rubber tube, the friction surface of the inner wall of the upward-spinning rubber tube contacts the projectile. Under the action of the driving element 20, the pressure pad 50 applies pressure to the upward-spinning rubber tube, and the friction surface of the upward-spinning rubber tube applies a forward or backward frictional force to the projectile, forcing the projectile to rotate counterclockwise or clockwise backward. Finally, driven by the high-pressure airflow, the projectile is rotated and ejected. Preferably, a fixing element 70 may be provided near the output end 122 of the second housing 12 to prevent the upper spiral rubber tube from rotating and sliding out of the housing 10.

[0037] Combination Figure 2 and Figure 8As shown, the driving element 20 is an adjusting disc rotatably fitted onto the input end 121 of the second housing 12, which can be injection molded from a polymer material. A first limiting groove 124 is provided on the outer circumferential surface of the input end 121 of the second housing 12 for fixing the adjusting disc. An involute spiral groove 21, distributed around its rotation center, is formed on the inner annular surface of the adjusting disc facing the output end. The first end 31 of the rocker arm 30 is inserted into the spiral groove 21. When the adjusting disc rotates, based on the involute geometry of the spiral groove 21, the spiral groove 21 converts the rotational displacement into an axial displacement component, driving the first end 31 of the rocker arm 30 to move axially. The rocker arm 30 pivots around the pin 112, converting the rotational input of the adjusting disc into a linear output of the second end 32 of the rocker arm 30 through the lever principle, ultimately transmitting a controllable linear force to the pressure pad 50.

[0038] To better accommodate the adjustment disc, preferably, the first end 31 of the rocker arm 30 extends horizontally, reducing the input force required for the adjustment disc. More preferably, the rocker arm 30 is angled from the pin hole 33 to the second end 32 along the axial direction. This angled configuration makes the contact stress distribution at the second end 32 more uniform, helping to extend the life of the rocker arm 30.

[0039] In some embodiments, the outer circumference of the adjustment disc opposite to the output end 122 is provided with a gear scale 24, which facilitates the user to accurately adjust the rotation gear of the adjustment disc. Preferably, the outer periphery of the adjustment disc is provided with anti-slip texture 23, which facilitates the user to turn the adjustment disc with their fingers.

[0040] Preferably, the inner ring surface of the adjusting disc is further provided with anti-loosening ratchet 22, and the input end 121 of the second housing 12 is further fitted with an abutment plate 126 for abutting against the anti-loosening ratchet 22, which can prevent external factors (such as vibration) from changing the setting of the adjusting disc. Preferably, the abutment plate 126 is connected to the mounting side wall 111 of the first housing 11, and a gap is left in the mounting side wall 111 for the first end 31 of the rocker arm 30 to extend out. The outer peripheral surface of the input end 121 of the second housing 12 is further provided with a second limiting groove 125, wherein the second limiting groove 125 is set closer to the input end 121 than the first limiting groove 124. The second limiting groove 125 is fitted with a pressure ring 60 for locking the adjusting disc to the input end 121 of the second housing 12, and the pressure ring 60 is preferably made of elastic material.

[0041] The working principle of this utility model is as follows: When the rotating drive element 20 is rotated, the involute spiral groove 21 on its inner circumference drives the first end 31 of the rocker arm 30 to move, causing the rocker arm 30 to rotate up and down around the pin 112. The second end 32 of the rocker arm 30 presses against the transmission element 40, and through the cavity 41 of the transmission element 40, it drives the pressure pad 50 to move downward, thereby pressurizing the projectile. The displacement of the pressure pad 50 is proportional to the rotation angle of the drive element 20, which can achieve precise ballistic adjustment.

[0042] This invention achieves precise adjustment of the projectile's spin force through an optimized orthogonal pressurization structure, ensuring good stability of the projectile components while maximizing the contact area between the projectile and the retaining ring, thus utilizing the Magnus effect more efficiently. This technological advantage directly translates into improved shooting accuracy, extended effective range, and significantly improved ballistic consistency. Furthermore, this orthogonal pressurization structure also boasts advantages such as compact structure and long service life.

[0043] The above embodiments are merely illustrative of the technical solutions of this utility model. Those skilled in the art can make equivalent modifications within the scope of the claims. For example, replacing the driving element with an electric servo mechanism, or using ceramic material to prepare the pressure pad 5040, etc., all fall within the protection scope of this utility model.
