Description
Technical Field
[0001] The utility model belongs to the field of toy bullets, in particular to a cylindrical toy bullet used in a serial magazine. Background Art
[0002] Currently, there are spherical bullets, cylindrical bullets, disc bullets and other types of bullets on the market. This patent is applied to the field of cylindrical bullets. Since most toy bullets on the market are soft bullets, the soft bullets are squeezed and arranged in parallel magazines. The bullets in the magazines are squeezed between the cylindrical surfaces of the bullets, causing the cylindrical bullets to form upper and lower extrusion flat marks, and even the bullets are squeezed into an elliptical cylinder. This cylindrical surface flattening caused by parallel compression is called parallel flattening. Parallel flattening leads to a series of disadvantages such as reduced air tightness of the bullet, low reuse rate of old bullets, low specific kinetic energy, and low accuracy.
[0003] The cylindrical bullets currently sold on the market are mainly loaded by squeezing the cylindrical surface of the bullet body. This type of parallel arrangement of bullets directly installed in parallel magazines is commonly used for soft bullets with a diameter of 13mm. Soft bullets are referred to as soft bullets. There are short soft bullets with suction cups of 32-36mm in length and 13mm in diameter, short soft bullets of 36-42mm in length and 13mm in diameter, and long soft bullets of 68-72mm in length and 13mm in diameter. The ratio of the length to the diameter of the above soft bullets is between 2.46 and 5.5 times. They have the defects of being relatively long, easy to bend, low accuracy and reuse rate, large self-weight coefficient, and low safety factor. Summary of the Invention
[0004] The utility model is aimed at developing a special cylindrical bullet for a magazine with serial loading. The bullets are serially loaded in the inner cavity of the cylindrical magazine by connecting the head of one bullet with the tail of another bullet. Since the cylindrical surface of the bullet is surrounded by the inner cavity of the cylindrical magazine, there is no parallel flattening defect. The hourglass structure cooperates with the blocking mechanism of the serial magazine to achieve the function of blocking the bullet and loading and unloading the bullets one by one. This bullet loading method of serially connecting the head and tail instead of parallel connection of the bullet bodies effectively solves the defect of parallel flattening of the bullet bodies.
[0005] In order to achieve the above-mentioned purpose, the utility model provides a cylindrical bullet for use in toys, wherein the bullet adopts an hourglass body structure, and this hourglass body structure has three parts: an upper body, a middle waist, and a lower body. The implemented technical solutions include a basic hourglass body bullet, an inner cone hourglass body bullet, a truncated cone hourglass body bullet, a combined hourglass body bullet, an hourglass-shaped jacket, and an hourglass body warhead; the implementation technology provides one or more technical solutions, which have the following technical effects based on the basic structure of the hourglass body and can be implemented in combination with each other.
[0006] The hourglass body has a cylindrical upper body, a narrow middle waist, and a cylindrical lower body; the top surface of the upper body is the bullet nose surface; the bottom surface of the lower body is the bullet tail surface; the middle waist is located between the upper body and the lower body, and has a structure that is waisted toward the axis of the column; the inner cavity is divided into a semi-closed inner cavity and an open middle cavity.
[0007] The mid-waist has three distinct features: upper waist, mid-waist, and lower waist. The mid-waist is located between the upper and lower waists. The waist tapers in three ways: steep at the upper waist and gentle at the lower waist, steep at the upper waist and steep at the lower waist, or gentle at the upper waist and gentle at the lower waist. The mid-waist works with a serial magazine to lock bullets. The narrowing structure of the mid-waist is relatively wide, providing excellent airflow guidance. The use of soft materials allows the narrowed area of the mid-waist to have a longer collapse stroke during impact, improving the cushioning coefficient and indirectly increasing the safety factor.
[0008] The basic hourglass-shaped bullet is an hourglass-shaped bullet with an inner cavity, and has an upper body, a middle waist, a lower body and an inner cavity.
[0009] The inner cone hourglass bullet is a basic hourglass bullet with an additional cone structure in the inner cavity. The cones are divided into four types according to their functions: buffer cone, counterweight cone, support cone, and composite cone.
[0010] The truncated cone hourglass bullet is formed by extending the upper body bullet surface into a truncated cone column structure on the basis of the inner cone hourglass body; the outer facade of the truncated cone column can be provided with transverse grooves or oblique grooves, and the grooves can be opened.
[0011] The combined hourglass-shaped bullet is a combination of a bullet and an hourglass-shaped body; the hourglass-shaped body comprises an upper body, a middle waist and a lower body; and the interior of the bullet and the hourglass-shaped body adopts a serial connection structure.
[0012] The hourglass-shaped jacket is an hourglass-shaped tubular structure, which is arranged on the outer facade of the hourglass body, wraps around and fits the waist, and can also be extended to fit the upper and lower body.
[0013] The hourglass-shaped bullet is a bullet with an hourglass-shaped structure, which has three parts: an upper body, a lower body, and a middle waist; the waist can be provided with a hole.
[0014] The tail surface of the lower body, that is, the tail surface of the bullet and the bullet surface adopt a socket structure to improve the serial extrusion deformation problem of the head and tail between serial bullets; the socket structure includes a head-flat tail-flat socket structure, a tail-concave head-convex socket structure, and a tail-convex head-concave socket structure. The latter two socket structures can align and match the concave and convex surfaces of the bullet head in the case of serial extrusion, which has the function of correcting the deviation of the bullet; the tail-concave head-convex socket structure further improves the capacity of serial loading.
[0015] The buffer vertebral body is a vertebral body structure located near the top surface of the upper body and is used for buffering impact.
[0016] The counterweight vertebra is a vertebral structure placed near the inner cavity of the upper body and is used to adjust the counterweight of the bullet.
[0017] The supporting vertebral body is a vertebral body structure that fits the inner cavity and is used to strengthen the strength of the inner cavity.
[0018] The composite cone is a cone structure that is sleeved between the warhead and the hourglass body. Its structure adopts a serial structure, which includes a Y-shaped structure, a T+arrow-shaped structure, a Y+inverted T structure, a double-arrow structure, an I-shaped structure, a Y+inverted Y structure, etc. The hourglass-shaped outer shell is a Y+inverted Y serial structure.
[0019] Furthermore, bullets with an hourglass body structure utilize an ultra-short-proportion structure to increase magazine capacity. The ratio of the bullet's total length to its diameter is between 1 and 2 times. For example, a 13mm diameter soft-body bullet has a length range of 13mm to 26mm, unlike the 2.46 to 5.5 times ratio of cylindrical soft-body bullets currently on the market. This reduction in size offers advantages such as reduced weight, lower wind resistance, smaller friction surface, and lower specific kinetic energy.
[0020] Optionally, the hourglass body structure may be provided with transverse grooves, and air guide holes may be opened in the transverse grooves.
[0021] Optionally, inclined grooves are provided on the outer facade of the column along the direction of the elastic body, and the number of the inclined grooves is ≥3.
[0022] Optionally, the outer shell structure provided on the cylindrical surface of the hourglass body may also be implemented by a thin film coating.
[0023] Preferably, the mid-waist has a structure that is steep at the top and gentle at the bottom, such as a ><-shaped structure that is steep at the top and gentle at the bottom, a ][-shaped structure that is steep at the top and gentle at the bottom, etc.
[0024] Preferably, the lower body tail surface is preferably equipped with a bullet with a concave tail and a convex head socket structure for capacity expansion loading.
[0025] Preferably, the depth of the narrowed waist is ≥ 10% of the cylinder diameter.
[0026] Preferably, the bottom edge of the column of the lower body is contracted into an obtuse angle surface, and a groove is provided on the tail surface of the lower body.
[0027] Preferably, the inclined groove is characterized in that one side of the groove surface is steeper than the other side of the groove surface.
[0028] In summary, the technical effects and advantages of this utility model
[0029] 1. The hourglass-shaped bullet is developed for serial magazines and is loaded into the magazine in a head-to-tail manner. Since the inner cavity of the serial magazine is a cylindrical cavity, the cylindrical surface of the bullet is supported by the cylindrical cavity, and the squeezing of the bullets will not cause parallel flattening or ovality of the cylinder. This makes the cylindrical bullet more airtight when entering the launch tube. This not only improves the accuracy of the bullet body, but also increases the reuse rate of old bullets, reducing indirect costs.
[0030] 2. The middle waist of the hourglass body is thinner in diameter than the upper and lower bodies, and there is a wide crumple zone. The crumple rate during impact is much greater than the crumple rate of the upper and lower bodies. The cushioning effect is better than the cylindrical bullets currently on the market, further improving the safety factor.
[0031] 3. Based on the same initial velocity of the bullet, the ultra-short cylindrical bullet of the present invention further improves the safety factor of the impact and reduces the specific kinetic energy due to the reduction in volume and weight, and is particularly suitable for the field of children's soft bullets with a higher safety factor.
[0032] 4. The use of a jacket structure further enhances the strength of the soft-bodied bullet.
[0033] 5. The use of a serial structure further improves the stability and durability of the combined warhead.
[0034] 6. The sleeve-jointed structure uses the pressure of the spring in the magazine to align the head of the next bullet with the tail of the previous bullet. In particular, the deformed convex bullet head can align with the concave area of the tail surface of the previous bullet under serial pressure to achieve the purpose of bullet head deviation correction, indirectly improving the utilization rate and flight accuracy of the skewed bullet head. At the same time, the concave-tail-convex sleeve-jointed structure shortens the length of serial loading and further increases the loading capacity. BRIEF DESCRIPTION OF THE DRAWINGS
