Description

Technical Field

[0001] The utility model belongs to the technical field of daily necessities, and particularly relates to a webbing adjusting device. Background Art

[0002] In a safety helmet, the adjustment of the webbing is very important because it ensures that the safety helmet can fit the wearer's head, providing comfort and stability, preventing the safety helmet from shifting or falling off due to head movement during work, thereby effectively improving the safety protection effect.

[0003] Patent No. CN213281776U discloses a webbing adjusting device, which includes a buckle body. A first connecting arm and a second connecting arm are arranged on the buckle body, and the first connecting arm and the second connecting arm are arranged at a predetermined included angle; a first through hole for one end of the first webbing to pass through is arranged at the end of the first connecting arm, and a second through hole for one end of the second webbing to pass through is arranged at the end of the second connecting arm; the buckle body includes a first surface and a second surface arranged away from each other, and a webbing movable locking device is further arranged on the buckle body; the webbing movable locking device is arranged on the second surface, and the webbing movable locking device locks and fixes the first webbing and the second webbing on the buckle body.

[0004] However, both webbings only pass through one through hole and are clamped by the webbing movable locking device. There is no relatively stable acting force between the through hole and the webbing, and the webbing is prone to relative sliding in the through hole when stressed. Thus, when the movable locking device is loosened, the webbing will retract relatively quickly, resulting in the webbing detaching from the buckle body, and when adjusting the tightness of the webbing, a greater force is required to tighten the webbing. Summary of the Invention

[0005] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a webbing adjusting device, which increases the resistance between the webbing and the adjusting device, and solves the problem that the webbing is prone to relative sliding with the buckle body of the adjusting device, resulting in the webbing being easily detached from the adjusting device.

[0006] The technical solution of the utility model: A webbing adjusting device includes a buckle body. The buckle body includes two mounting arms extending obliquely upward to the left and right sides respectively. Each mounting arm includes a plurality of adjusting through holes for the webbing to pass through, and a partition is formed between adjacent adjusting through holes. The webbing winds around one side of the partition and passes through each adjusting through hole in turn. A median through hole is arranged on the buckle body, and the median through holes are all between the two mounting arms. The two webbings respectively pass through the adjusting through holes on the corresponding mounting arms on the left and right sides and then pass downward through the median through hole.

[0007] By adopting the above technical scheme, a plurality of adjustment through holes are set on each mounting arm, and the webbing passes through the corresponding adjustment through holes and the middle through hole in sequence by bypassing the partitions between adjacent adjustment through holes, thereby greatly increasing the contact area between the webbing and the buckle body, so that when the webbing is in a relaxed state, a greater force is required to achieve relative movement with the buckle body, so that the connection between the webbing and the buckle body is more secure, and the device and the webbing are effectively prevented from sliding. The webbing is inserted into both sides and then passes out downward, so that the middle through hole is set at a certain angle with the adjustment through hole, and the webbing needs to be bent to a certain degree before it can pass through the middle through hole. Therefore, the side of the webbing in the bent state can also be subjected to resistance from the buckle body, which can further prevent the webbing from slipping off by itself when the webbing is not locked.

[0008] The buckle body is provided with an opening, and partitions are formed between the opening and the adjacent adjustment through hole and between the opening and the middle through hole. The webbing passes through the adjustment through hole and then wraps around the corresponding partition to pass through the opening and the middle through hole in turn.

[0009] By setting the opening, two circumventable partitions are added, so that after the webbing passes through the corresponding adjustment hole, it passes through the opening around the partition between the adjustment hole and the opening, and then passes through the middle hole around the partition between the opening and the middle hole, thereby further increasing the contact area between the webbing and the buckle body, making the connection between the webbing and the buckle body more stable.

[0010] A further configuration of the utility model is as follows: each mounting arm comprises two adjustment through holes, and the two mounting arms are symmetrically arranged on both sides of the buckle body.

[0011] By adopting the above-mentioned further arrangement, the number of adjustment holes on each mounting arm is controlled, and the resistance between the webbing and the buckle body is enhanced to avoid the situation where people need great force to pull the webbing when manually adjusting the position of the webbing. In addition, the symmetrically arranged mounting arms can keep the two webbings moving synchronously when pushing the buckle body, thereby keeping the buckle body centered.

[0012] The utility model is further configured as follows: a cover plate is provided on the opening, and a gap is formed between the cover plate and the opening for two webbings to pass through.

[0013] By adopting the above further arrangement, the cover plate can limit the height of the webbing in the opening, prevent the webbing from tilting in the opening, keep both webbings taut, ensure that the webbings are subjected to friction with the buckle body when in motion, and further prevent the webbing and the buckle body from sliding.

[0014] The utility model is further configured as follows: the cover plate corresponds to the shape of the opening, one end of the cover plate is a fixed end fixedly connected to the inner wall of the opening away from the mid-position through hole, and the other end of the cover plate is a free end tilted above the end of the opening close to the mid-position through hole.

[0015] With the above further arrangement, the cover plate is located outside the opening, blocking the webbing exposed in the opening and preventing the webbing at the bending part from directly contacting the outside. One end is tilted up to leave a gap between the cover plate and the opening for two webbings to pass through.

[0016] A further arrangement of the present utility model: The cover plate and the buckle body are integrally formed, and a rib structure is provided between the cover plate and the buckle body.

[0017] With the above further arrangement, the rib structure can enhance the connection strength between the cover plate and the buckle body, prevent the cover plate from being broken and damaged, and is integrally formed without a connection structure, reducing the probability of failure and saving maintenance and manufacturing costs.

[0018] A further arrangement of the present utility model: The two mounting arms are arranged at a certain angle, and a clearance is left between the outer ends of the two mounting arms and the upper side of the buckle body.

[0019] With the above further arrangement, the clearance leaves space for the ears of the safety helmet user to be placed, avoiding contact and affecting the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0024] It should be noted that in the description of the present utility model, all directional indications (such as up, down, front, back...) are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.

[0025] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0026] like Figure 1-2 As shown, the up, down, left, and right directions mentioned in this embodiment are as follows Figure 1 As shown in the figure, a webbing adjustment device includes a buckle body 1, the buckle body 1 includes two mounting arms 2 extending obliquely upward to the left and right sides respectively, the two mounting arms 2 are arranged at a certain angle, each mounting arm 2 includes a plurality of adjustment through holes 3 for the webbing to pass through in sequence, and in this embodiment, the number of adjustment through holes 3 on each mounting arm 2 is controlled, and preferably two adjustment through holes 3 are arranged on each mounting arm 2, while enhancing the resistance between the webbing and the buckle body 1, avoiding too many adjustment through holes so that people need great force to pull the webbing when manually adjusting the webbing position.

[0027] The two adjustment through holes 3 of each mounting arm 2 are separated by a partition plate 7 , and the webbing is wound around a side surface of the partition plate 7 to sequentially pass through the two adjustment through holes 3 on the corresponding mounting arm 2 .

[0028] An opening 4 is provided on the buckle body 1, and the opening 4 is located between the two mounting arms 2. The opening 4 and the two adjacent adjustment holes 3 on the left and right are both provided with partitions 7. After each webbing passes through the corresponding two adjustment holes 3 in sequence, it is wrapped around the partition 7 and passes through the opening 4.

[0029] The buckle body 1 is provided with a central through hole 6 at the lower side of the opening 4, and the central through hole 6 is also located between the two mounting arms 2. The two mounting arms 2 are symmetrically arranged on both sides of the central through hole 6. A partition 7 is constructed between the central through hole 6 and the opening 4 to achieve isolation. After passing through the opening 4, the two webbings are wrapped around the partition 7 and then pass through the central through hole 6 in parallel.

[0030] Thus, the two webbings pass through the adjustment holes 3 on the corresponding mounting arms 2 on the left and right sides respectively, enter the opening 4, turn, and then pass downward through the middle through hole 6.

[0031] A cover plate 5 is provided on the opening 4. There is a gap between the cover plate 5 and the opening 4 for two webbings to pass through. The cover plate 5 can limit the height of the webbing in the opening 4 to prevent the webbing from curling up in the opening 4, so that both webbings can be kept taut and covered on the partition 7, ensuring that the webbings can be subjected to friction resistance with the buckle body 1 when they move, further preventing the webbing and the buckle body 1 from sliding.

[0032] In this embodiment, the four adjustment holes 3 and the opening 4 are arranged along an arc shape, the middle hole 6 is located at the lower side of the arc shape, and a certain angle is formed between the adjustment hole 3 and the middle hole 6, so that the webbing can pass through the middle hole 6 after being bent at a certain angle in the opening 4, and thus the side edge of the webbing in the bent state contacts with the buckle body 1 and is subject to a certain resistance;

[0033] When the webbing passes through the two adjustment holes 3, the opening 4 or the middle hole 6, it needs to be wrapped around the corresponding partition 7, which greatly increases the contact area between the webbing and the buckle body 1, so as to enhance the upper limit of the resistance between the webbing and the buckle body 1 and make the connection between the webbing and the buckle body 1 more secure.

[0034] The end surface of each partition 7 that is contacted by the webbing is lower than the outer end surface of the adjacent buckle body 1, so that the webbing will not protrude outside the buckle body 1 when it is wrapped around one side of the partition 7. Therefore, when it comes into contact with the outside world, the outer surface of the buckle body 1 contacts the part of the webbing wrapped around the partition 7 before, thereby protecting and reducing the wear of the webbing.

[0035] Furthermore, the cover plate 5 corresponds to the shape of the opening 4, one end of the cover plate 5 is a fixed end fixedly connected to the inner wall of the opening 4 away from the mid-position through hole 6, and the other end of the cover plate 5 is a free end tilted above the end of the opening 4 close to the mid-position through hole 6. The cover plate 5 is outside the opening 4, blocking the exposed webbing in the opening 4, maintaining the appearance while avoiding direct contact between the webbing at the bend and the outside world, and one end is tilted to leave a gap between the cover plate 5 and the opening 4 for the two webbings to pass through.

[0036] The cover plate 5 and the buckle body 1 are integrally formed without the need for a connecting structure, which reduces the probability of failure and saves maintenance and manufacturing costs. A rib structure is provided between the cover plate 5 and the buckle body 1 to enhance the connection strength between the cover plate 5 and the buckle body 1 and reduce the probability of the cover plate 5 breaking or being damaged. A pattern structure may be engraved on the cover plate 5 to enhance the aesthetics.

[0037] The two mounting arms 2 are arranged at a certain angle, and the buckle body 1 is a V-shaped structure as a whole. An avoidance gap 8 is left between the outer ends of the two mounting arms 2 and the upper side of the buckle body 1. The two webbings are respectively passed around the user's ears at the upper left and upper right and then passed through the mounting arms 2. The space left by the avoidance gap 8 can be used for the ears of the helmet user to avoid contact and affect the user experience, so as to conform to the human body structure.

[0038] Specifically, by setting two adjustment through-holes 3 on each mounting arm 2, the two webbings need to wind around different partitions 7 multiple times to sequentially pass through the corresponding adjustment through-holes 3, openings 4, and middle-position through-holes 6, greatly increasing the contact area between the webbing and the buckle body 1. Even when the webbing is in a relaxed state, a greater force is required for the webbing to move relative to the buckle body 1, preventing the buckle body 1 from slipping off by itself, making the connection between the webbing and the buckle body 1 more secure. Moreover, the adjustment through-hole 3 and the middle-position through-hole 6 are arranged at a certain angle, and the webbing needs to be bent to a certain extent in the opening 4 to pass through the middle-position through-hole 6. For the webbing in this bent state, its side can also be resisted by the buckle body 1, further preventing the webbing from slipping off by itself when the webbing is not locked.

[0039] In summary, the two webbings enter from the upper left and upper right of the buckle body 1 along the extension direction of the mounting arm 2, sequentially pass through the two adjustment through-holes 3 and wind around the outer surface of the partition 7 between the two adjustment through-holes 3, then wind around the outer surface of the partition 7 between the adjustment through-hole 3 and the opening 4 and pass through the opening 4. After the two webbings are bent at a certain angle at the opening 4, they pass through the gap between the opening 4 and the cover plate 5 and wind around the outer surface of the partition 7 between the opening 4 and the middle-position through-hole 6, and then together pass through the middle-position through-hole 6 and extend downward. Subsequently, they are connected to the locking device of the safety helmet below, and by pushing the buckle body 1 to slide relative to the webbing, the tightness of the webbing can be adjusted.
