Description

Technical Field

[0001] The utility model relates to the technical field of connecting pieces, in particular to a connecting piece and a safety helmet with the connecting piece. Background Art

[0002] Most of the existing helmets adjust the size of the head and tail through the hat hoop, and some hat hoop adjustment devices are rack-type designs, such as the helmet hat hoop tension adjustment device published by the publication number CN112869274A, which adjusts the tightness of wearing by moving the racks arranged on both sides of the helmet relative to each other or away from each other, and the knob adjustment is convenient and practical. However, the existing rack and the helmet shell or the hat hoop are usually connected by buttons or knobs. The problem is that it is easy to fall off or wear and break during long-term use, resulting in low overall durability. If the overall strength and stability of the connection need to be improved, the amount of material needs to be increased, thereby further increasing the overall deadweight and increasing the material cost; and if the ordinary knob connection method is adopted, the whole process needs to be processed, and the stacking is high after installation, the hollow drum is large, and the volume is large, which is extremely inconvenient during wearing and transportation. Therefore, the utility model aims to further develop a connector and a helmet with the connector to better meet actual needs. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0029] See also Figure 1 to Figure 5 shown.

[0030] In this embodiment, the connecting piece is used to connect the rack 2 to the helmet hoop 1. In other embodiments, the connecting piece can also be used to connect the rack 2 to the helmet shell, or to other two connected bodies that need to be connected.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the connecting piece includes a first mounting hole 5, a connecting piece body 4, and a locking piece 3.

[0032] The first mounting hole 5 is arranged on the cap hoop 1 , and the first mounting holes 5 are arranged on two opposite sides of the cap hoop close to the two ears.

[0033] The connector body 4 and the locking member 3 are respectively arranged on two sides of the first mounting hole 5 .

[0034] The connector body 4 is disposed at one end of the rack 2 . Similar to the prior art, one end of the two racks 2 are connected via a rack adjustment mechanism, and the ends of the two racks are respectively connected to the corresponding first mounting holes 5 .

[0035] The connector body 4 includes an enlarged connecting piece 45 disposed at one end of the rack 2 . A second mounting hole 41 is disposed in the middle of the enlarged connecting piece 45 . The diameter of the second mounting hole 41 is smaller than that of the first mounting hole 5 .

[0036] like Figure 5 As shown, the first paddle 42 and the bulged connecting piece 45 are integrally formed. In a preferred embodiment, the first paddle 42 and the bulged connecting piece 45 are arranged vertically or at an inclined angle close to a right angle. A first hook foot 43 is provided at the tail end of the first paddle 42 away from the bulged connecting piece 45. The first paddle 42 passes through the first mounting hole 5 and abuts against the edge of the first mounting hole 5 through the first hook foot 43.

[0037] In a preferred embodiment, the first hook foot 43 is arranged perpendicular to the first paddle 42 or at an inclination angle close to a right angle and extends outward, and multiple first paddles 42 are dispersedly arranged along the outer edge of the second mounting hole 41. The first paddle 42 has a certain deformation ability, so that after the first hook foot 43 passes through the first mounting hole 5, the hook foot extending outward abuts against the edge of the first mounting hole 5 to prevent slipping.

[0038] like Figure 5 As shown, the locking member 3 includes an independently arranged locking cover 33. In a preferred embodiment, the second paddle (not shown) is integrally formed with the locking cover 33. A plurality of second paddles are dispersedly arranged on the surface of the locking cover 33, and the plurality of second paddles are arranged perpendicularly to the surface of the locking cover 33 or arranged at an inclined angle close to a right angle. A second hook foot 32 is arranged at the tail end of the second paddle, and the second paddle passes through the first mounting hole 5 and the second mounting hole 41 on the connector body 4 in sequence, and the second hook foot 32 abuts against the edge of the second mounting hole 41 to prevent it from falling off. The second paddle passes in the opposite direction to the first paddle 42.

[0039] In a preferred embodiment, the second hook foot 32 is arranged perpendicular to the second paddle or at an inclination angle close to a right angle and extends outward, and the second paddle has a certain deformation ability, so that the second paddle passes through the first mounting hole 5 and the second mounting hole 41 in sequence, and then abuts against the edge of the second mounting hole 41 through the hook foot extending outward.

[0040] Therefore, through the above-mentioned arrangement, the connector body 4 forms a preliminary connection after passing through the first mounting hole 5, and the locking member 3 successively passes through the first mounting hole 5 and the second mounting hole 41 on the connector body 4 to complete further locking, thereby ensuring the stability of the overall connection, and the installation is fast and flexible, and does not affect the rotation of the rack 2 after installation.

[0041] In a preferred embodiment, in order to further reduce the deadweight, a weight-reducing through hole 31 is provided on the enlarged connecting piece 45 of the connector body 4 or the locking cover 33 of the locking member 3; an inwardly concave weight-reducing groove 51 is provided on the outer edge of the first mounting hole 5 toward the connector body 4.

[0042] In other preferred embodiments, an inner recessed snap ring 53 is provided on the outer edge of the first mounting hole 5 facing the locking member 3, and the edge of the locking cover 33 is embedded in the snap ring 53, so that the edge of the locking cover 33 is embedded in the snap ring 53, thereby reducing the displacement of the locking cover 33 and playing a good limiting role.

[0043] As a further improvement of the present invention, a limiting groove 52 is provided on the outer edge of the first mounting hole 5 toward the connector body 4, and a limiting convex point 44 is provided on the connector body 4, and the limiting convex point 44 is matched with the limiting groove 52. Preferably, the limiting groove 52 is a concave hemispherical limiting groove 52, and the limiting convex point 44 is a hemispherical convex point structure. The limiting groove 52 and the limiting convex point 44 do not affect the rotation of the rack 2, and the rack 2 can be rotated by an appropriate thrust. When the limiting convex point 44 corresponds to the limiting groove 52, the rack 2 is positioned to a certain extent to prevent it from swinging flexibly.

[0044] The connecting piece of the utility model is particularly suitable for connecting a cap hoop 1 and a rack 2 in a safety helmet, and can be significantly improved after being used.

[0045] In the utility model, the connecting piece is preferably made of nylon material, so as to further improve the overall tensile toughness.

[0046] The utility model is also used to protect a safety helmet, which adopts the connector of the utility model, and the connector can firmly connect the rack 2 with the helmet body or the hat hoop 1 of the safety helmet, improve the strength of the connection, and further improve the overall durability. In addition, while improving the overall strength and durability, it can reduce the overall deadweight, save materials, and can be transported and assembled separately, saving storage space, and further reducing transportation costs and installation costs.
