Description

Technical Field

[0001] This utility model relates to the field of webbing connection, specifically to an adjustable chest strap clip. Background Technology

[0002] Chest strap clips are mainly used for backpack shoulder straps or running vacuum products. Non-adjustable chest strap clips specifically refer to connectors whose chest strap length cannot be adjusted. They are characterized by non-adjustable length, sturdy structure, and compact size. Their function is to prevent the above products from falling off or shifting significantly due to shaking during use. Compared with adjustable chest strap clips, they have advantages such as direct fixing effect, no adjustment cost, compatibility with multiple materials, no fixing limitations, low operating threshold, no learning cost, wear-resistant structure, and long service life. Existing non-adjustable chest strap clips are typically designed to be thick to ensure connection strength, which results in a noticeable foreign body sensation during use and reduces the user experience.

[0003] Therefore, it is necessary to provide a non-adjustable chest strap clip with a certain connection strength and the ability to reduce the feeling of foreign objects during use to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a non-adjustable chest strap clip, comprising: The elastic body has an upper part that is bent downward to form a hook portion. The inner side of the hook portion is provided with a latch protruding towards the elastic body. The latch abuts against the side of the elastic body near the hook portion and forms an inner space for threading a first webbing. Below the inner space is a locking area formed by the latch and the elastic body. The lower part of the elastic body is bent toward the locking area to form a threading portion. The threading portion has a threading opening for threading a second webbing.

[0005] Furthermore, as a preferred embodiment, the through-hole includes an abutting portion located at the end of the through-hole away from the snap-fit ​​area and a connecting portion located at the end of the through-hole close to the snap-fit ​​area. The through-hole is located on the connecting portion and connected to the abutting portion. The connecting portion is parallel to the elastic body, and the abutting portion is deflected toward the snap-fit ​​area.

[0006] Furthermore, preferably, the width of the connecting part is greater than that of the elastic body, the thickness is the same as that of the elastic body, the thickness of the connecting part is greater than that of the abutting part, and the edges of the elastic body are all chamfered.

[0007] Furthermore, as a preferred embodiment, the elastic body is provided with a tongue hole at the point where it abuts the locking tongue.

[0008] Furthermore, as a preferred embodiment, the connecting portion and the abutting portion form locking loops on the two sides where the abutting portion connects to the through-hole.

[0009] Furthermore, as a preferred embodiment, the bent section of the hook portion near the elastic body is an inner hook portion, and the thickness of the inner hook portion is greater than that of the elastic body.

[0010] Furthermore, as a preferred embodiment, the side of the locking tongue near the engagement area is provided with a first inclined wedge surface.

[0011] Furthermore, as a preferred embodiment, the latch has a second inclined wedge surface on one side near the inner hook.

[0012] Furthermore, preferably, the slope of the first inclined wedge is greater than the slope of the second inclined wedge.

[0013] Furthermore, as a preferred embodiment, the angle between the working surface of the abutting portion and the working surface of the first webbing is 20°.

[0014] Compared with the prior art, the present invention provides a non-adjustable chest strap clip, which has the following beneficial effects: In this embodiment of the invention, the structural design of the chest strap clip, including the design of the abutment and insertion parts, distributes the pressure to two contact surfaces after the second webbing is connected, reducing the pressure received by a single component. The locking tongue and the space inside the hook restrict the space of the first webbing, thus connecting it. Simultaneously, the space inside the hook can accommodate the webbing that has been compressed under stress, reducing the degree to which the hook opens and delaying the time it takes for the webbing to exert force on the elastic body after expansion, thereby increasing tensile strength. Because the chest strap clip is made of elastic material, the hook and abutment parts connecting the locking tongue can deform and rotate to a certain extent. Due to their structural design, the rotation directions of the hook and abutment parts are opposite, thus offsetting some of the force on the chest strap clip and enhancing durability. Furthermore, the tongue hole and abutment parts are thinner than other components, while the inner hook part, which bears the force, is thicker than other components, giving the embodiment a lightweight and slim profile while maintaining a certain strength, significantly reducing the foreign body sensation associated with other products.

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Please see Figures 1-4 This utility model discloses an adjustable chest strap clip, comprising: The elastic body 1 has its upper part bent downwards to form a hook portion 2. The hook portion 2 and the elastic body 1 form a "J" shape. The inner side of the hook portion 2 is provided with a latch 21 that protrudes towards the elastic body 1 (the latch 21 is a boss, with its narrow side facing the side of the elastic body 1 closest to the hook portion 2). The latch 21 abuts against the elastic body 1. The latch 21, the elastic body 1, and the inner hook portion 22 constitute a hook inner space 4 (the hook inner space 4 is a semi-enclosed space). Below the space 4, the locking tongue 21 and the elastic body 1 form a locking area 5 (the locking area 5 is a semi-enclosed space, which has one less restrictive side compared to the hook inner space 4). During the installation process, the first webbing enters the hook inner space 4 from the locking area 5 and connects to the hook inner space 4. The space of the hook inner space 4 can accommodate the webbing that is squeezed after being stressed. The lower part of the elastic body 1 is bent toward the locking area 5 to form a through part 3. A through opening 31 is opened in the middle of the through part 3. The second webbing passes through the through opening 31 for installation.

[0018] In this embodiment, as Figure 1The threading part 3 includes a threading opening 31, an abutment part 32, and a connecting part 33. It should be noted that the connecting part 33 is parallel to the elastic body 1, the abutment part 32 is a bent part, the threading opening 31 is opened at the connection between the connecting part 33 and the abutment part 32, and the connecting part 33 is wrapped by a component around the threading opening 31. The threading opening 31 needs to be used for the second webbing to be threaded, so the width of the threading opening 31 needs to be greater than or equal to the width of the webbing. Therefore, the width of the connecting part 33 is greater than the size of the webbing. In order to save material, the width of the connecting part 33 is greater than that of the elastic body 1, and the width of the threading opening 31 is equal to that of the elastic body 1. In order to ensure the strength of the connecting part 33, the thickness of the connecting part 33 is the same as that of the elastic body 1. When the second webbing is threaded through the threading opening 31, the end of the abutting part 32 away from the threading opening 31 abuts against the second webbing, sharing the pressure of the second webbing on the threading opening 31. At the same time, in order to make it easier for the abutting part 32 to flip away from the locking area 5 when the pressure of the second webbing is too great (increasing the elasticity of the abutting part 32 and increasing the amount of deformation that can be produced when bearing pressure), the locking tongue 21 moves away from the locking area 5 to reduce the overall rotation angle of the chest strap clip, delay the time when the abutting part 32 breaks, and enhance the durability of the chest strap clip. The thickness of the abutting part 32 is thinner than that of the connecting part 33. Similarly, this design can also reduce the material used in the chest strap clip. Because there is a thickness difference between the connecting part 33 and the abutting part 32, and there is an included angle between the two working surfaces of the connecting part 33 and the abutting part 32, when the second webbing is inserted into the insertion opening 31 through the sides of the insertion opening 31 formed by the edges of the connecting part 33 and the abutting part 32, the edge of the second webbing can enter the locking opening 34 for a more stable connection.

[0019] like Figure 2 To facilitate personnel handling, the working surfaces of the elastic body 1, the abutment part 32, the hook part 2 facing away from the hook inner space 4, and the edges of the connecting part 33 are all chamfered. The working surface of the hook part 2 facing away from the hook inner space 4 gradually narrows in width from the hook inner space 4 to the corresponding position of the locking area 5, which helps to save materials. At the same time, in order to make it easy for the second webbing to pass through the insertion opening 31, the insertion opening 31 and the locking opening 34 are also chamfered.

[0020] like Figure 3The elastic body 1 has a tongue hole 11 at the corresponding position of the locking tongue 21. Part of the locking tongue 21 is exposed through the tongue hole 11. The locking tongue 21 can enhance the bending effect of the hook part 2 so that part of the locking tongue 21 passes through the tongue hole 11 to strengthen the tight fit between the locking tongue 21 and the elastic body 1. After the first webbing is installed, part of the first webbing can be sandwiched between the locking tongue 21 and the elastic body 1, so that the position of the first webbing is fixed after the embodiment is installed, eliminating the slippage phenomenon of the chest strap being clamped on the webbing. At the same time, it can also increase the sealing of the hook space 4, so that the locking tongue 21 enhances the effect of limiting the position of the first webbing after the first webbing is installed in the hook space 4. In addition, the tongue hole 11 acts as a weight reduction hole, further reducing the material usage of the elastic body 1.

[0021] like Figure 4 The bent section of the hook portion 2 near the elastic body 1 is the inner hook portion 22. The inner hook portion 22 is part of the hook inner space 4. The space of the hook inner space 4 can accommodate the webbing that is squeezed after being stressed, thereby reducing the degree to which the hook body is opened (the angle at which the hook portion 2 flips away from the snap-fit ​​area 5). This can delay the time point at which the first webbing exerts force on the inner hook portion 22 after being squeezed and expanded, which helps to increase the tensile strength. After the first webbing is squeezed and expanded in the hook inner space 4, the inner hook portion 22 bears the corresponding pressure. Therefore, the thickness of the inner hook portion 22 is thicker than that of the hook portion 2 and the elastic body 1, in order to enhance the robustness and durability of the embodiment. The locking tongue 21 is a raised boss. Its side near the hook space 4 has a second inclined wedge surface, and its side near the engagement area 5 has a first inclined wedge surface. The first inclined wedge surface makes it easier for the first webbing to pass through the engagement area 5 during installation. Simultaneously, during installation, the first webbing gradually moves towards the contact area between the locking tongue 21 and the elastic body 1 until the pressure increases to the point that the locking tongue 21 causes the hook portion 2 to slightly rotate and deform away from the elastic body 1, entering the hook space 4. At this point, the first inclined wedge surface prevents pressure buildup. The first webbing is pressed against the locking tongue 21 and broken. The second inclined wedge surface allows the first webbing to enter and be removed more smoothly when it moves towards the inner space 4 of the hook. The space formed by the second inclined wedge surface and the inner hook 22 also matches the state of the webbing when it is stacked (the webbing is far away from the locking tongue 21 and the thickness is concentrated on the side of the inner hook 22). At the same time, the closer it is to the area where the locking tongue 21 abuts against the elastic body 1, the thicker the wedge surface of the locking tongue 2 becomes. This allows the locking tongue 2 to still play a certain blocking and fixing effect after the locking tongue 21 is rotated and deformed away from the elastic body 1.

[0022] In a preferred embodiment, the slope of the second inclined wedge is less than that of the first inclined wedge. The first inclined wedge is only applicable to the installation of the first webbing, while the second inclined wedge is not only used for the installation and removal of the first webbing, but also involves the stacking of webbing. The slope affects the space inside the hook 4 for stacking webbing, so the slope of the second inclined wedge is smaller.

[0023] It should be noted that when the first webbing and the second webbing are installed, the first webbing is in a vertical plane, the second webbing passes through the through-hole 31, and the abutting part 32 abuts against part of the second webbing. The angle between the working surface of the abutting part 32 and the vertical plane in which the first webbing is located is 20°.

[0024] In a preferred embodiment, under normal use, the second webbing is connected to the chest strap clip through the through-hole 31. At this time, the abutment part 32 abuts against the second webbing. When the webbing is pulled out, it is resisted by the through-hole 31 and the abutment part 32. The first webbing is connected through the hook space 4. When the tension of the two webbings is too high, the webbing through the through-hole 31 will increase the pressure on the abutment part 32 due to the increased tension, causing the abutment part 32 to deform and rotate in a counterclockwise direction (that is, the abutment part 32 is directed towards the direction of the minimum angle parallel to the elastic body 1); the webbing connected to the hook inner space 4 will stack due to the increased tension, and apply pressure to the inner hook part 22. The expansion of the stacked webbing will cause the locking tongue 21 to deform and rotate in a clockwise direction (away from the hook part 31), connecting the hook inner space 4 and the locking area 5, thereby delaying the time of breakage of the embodiment. At this time, the force direction of the first webbing and the second webbing on the chest strap clip is in a straight line.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
