Description

Technical Field

[0001] This utility model relates to the field of anti-slip buckle technology, and in particular to an anti-slip buckle for a backpack. Background Technology

[0002] Anti-slip buckles on backpacks typically refer to components designed to enhance the stability and comfort of the backpack. These devices help ensure the straps remain in the correct position on the user's shoulders, preventing them from slipping and thus improving the carrying experience, especially important during sports or prolonged wear.

[0003] However, in the existing technology, most backpack anti-slip buckles are D-ring buckles. Although D-ring buckles are easy to operate, their anti-slip effect is poor. When the backpack is heavy, the adjustment strap is easy to slip, which makes the backpack shoulder straps uneven and reduces comfort. Moreover, there is friction between the adjustment strap and the D-ring buckle when adjusting, making it difficult to adjust and thus reducing the adjustment effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that most backpack anti-slip buckles in the prior art are D-ring buckles. Although D-ring buckles are convenient to operate, their anti-slip effect is poor. When the backpack is heavy, the adjustment strap is easy to slip, which makes the backpack shoulder straps uneven and reduces comfort. Moreover, there is friction between the adjustment strap and the D-ring buckle during adjustment, which makes adjustment difficult and reduces the adjustment effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a backpack anti-slip buckle, comprising: a rectangular frame, and further comprising:

[0006] An anti-slip component, disposed inside the rectangular frame, is used to position the backpack straps. The anti-slip component includes:

[0007] A hollow block is positioned at the center of the interior of the rectangular frame;

[0008] A long strip is provided on the top of the hollow block, and multiple positioning cones are provided on the bottom of the long strip for positioning the shoulder strap;

[0009] A positioning component is disposed on the outer surface of the rectangular frame;

[0010] Adjustment components are located on both sides of the bottom of the rectangle.

[0011] Preferably, the anti-slip component also includes:

[0012] Multiple through holes are formed on the top of the hollow block, allowing the positioning cone to be inserted;

[0013] A rubber pad is provided at the lower end of the interior of the hollow block for anti-slip purposes on the shoulder strap;

[0014] Two handles are located on both sides of the long strip.

[0015] The technical effect of adopting the above-mentioned further solution is that the long strip plate drives multiple positioning cones to embed into the interior of the through hole, which can position the strap with the embedded hollow block. The sharp end of the positioning cone is embedded in the interior of the strap, improving the stability of the strap. The rubber pad further improves the friction of the strap, making the strap less prone to slipping.

[0016] Preferably, the positioning component includes:

[0017] Two positioning holes are provided on both sides of the long strip for limiting the position of the long strip;

[0018] Two grooves are formed at the center of the upper end of the rectangular frame, and a limiting pin is movably embedded in the interior of each groove for positioning the long strip.

[0019] Two circular blocks are positioned at opposite ends of the two limiting pins. A first spring is fixedly connected to the outer surface of each of the two circular blocks. The other end of the first spring is connected to the inside of the groove, which can drive the limiting pins to move.

[0020] The technical effect of adopting the above-mentioned further solution is that the second spring can drive the long strip plate to fit into the hollow block, so that the positioning cone can be better embedded in the inside of the strap for positioning, and the two first springs drive the limiting pin to be embedded in the inside of the positioning hole, which can position the long strip plate.

[0021] Preferably, the adjustment component includes:

[0022] Two rectangular slots are provided on both sides of the bottom of the rectangular frame;

[0023] Two round rods are set inside the rectangular groove for adjusting the shoulder strap.

[0024] The technical effect of adopting the above-mentioned further solution is that when the shoulder strap moves, the round rod rotates inside the rectangular groove, which can improve the transmission effect, reduce resistance, and make it easier to adjust the shoulder strap.

[0025] Preferably, two circular grooves are formed on both sides of the top of the hollow block.

[0026] The technical effect of adopting the above-mentioned further solution is that the second spring can be embedded inside the circular groove, so that the long strip plate is flush with the rectangular frame.

[0027] Preferably, a second spring is provided inside each of the two circular grooves; the other end of the second spring is connected to the long strip plate.

[0028] The technical effect of adopting the above-mentioned further solution is that the second spring can drive the long strip plate to fit into the hollow block, so that the positioning cone can better position the shoulder strap.

[0029] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0030] 1. In this utility model, a long strip plate drives multiple positioning cones to embed into the interior of the through hole, which can position the shoulder strap embedded in the hollow block. The sharp end of the positioning cone is embedded into the interior of the shoulder strap, improving the stability of the shoulder strap. The rubber pad further improves the friction of the shoulder strap, making it less prone to slippage. The long strip plate can be pressed down by the handle. Two second springs are fixedly installed at the bottom of the long strip plate. The second springs can drive the long strip plate to fit against the hollow block, so that the positioning cones can be better embedded into the interior of the shoulder strap for positioning. The two first springs drive the limiting pin to embed into the interior of the positioning hole, which can position the long strip plate and make it flush with the rectangular frame. The limiting pin can be moved by pulling the round block.

[0031] 2. In this utility model, the positioning cone no longer positions the shoulder strap. Pulling the shoulder strap allows it to move inside the hollow block. The shoulder strap fits against the round rod, and the round rod rotates inside the rectangular groove when the shoulder strap moves. This improves the transmission effect, reduces resistance, and makes it easier to adjust the shoulder strap. Attached Figure Description

[0038] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0040] Example 1, as Figure 1-4 As shown, this utility model provides a backpack anti-slip buckle, including: a rectangular frame 1, an anti-slip component, a positioning component, and an adjustment component;

[0041] Anti-slip components include:

[0042] Handles 105 are fixedly installed on both sides of the long strip 103. The long strip 103 can be adjusted by pulling the handles 105, so that multiple positioning cones 112 fixedly installed at the bottom of the long strip 103 can move. The positioning cones 112 penetrate through the through holes 111 to position the shoulder strap embedded in the hollow block 101, improve the stability of the shoulder strap and prevent the shoulder strap from slipping. A rubber pad 102 is fixedly installed at the lower end inside the hollow block 101. The rubber pad 102 can increase the friction and make the shoulder strap less likely to slip.

[0043] In this embodiment, the long strip plate 103 drives multiple positioning cones 112 to be embedded in the through hole 111, which can position the strap embedded in the hollow block 101. The sharp end of the positioning cone 112 is embedded in the strap, which improves the stability of the strap. The rubber pad 102 further improves the friction of the strap, making the strap less prone to slipping.

[0044] Example 2, as Figure 1-4 As shown, the positioning component includes:

[0045] A second spring 114 is fixedly connected to both sides of the bottom of the long strip 103. The second spring 114 can drive the long strip 103 to fit against the top of the hollow block 101. The second spring 114 can be embedded in the inside of the circular groove 113, so that the long strip 103 is flush with the rectangular frame 1. The first spring 107 drives the limiting pin 106 to be embedded in the positioning hole 104. The positioning hole 104 is opened on both sides of the long strip 103, so that the long strip 103 is more stably embedded in the inside of the rectangular frame 1. The circular block 108 fixedly installed at one end of the limiting pin 106 can pull the limiting pin 106 to move, thereby moving the long strip 103. The circular block 108 is movably embedded in the groove 115 and will not protrude, which improves the aesthetics.

[0046] In this embodiment, the handle 105 can be used to press the long strip 103 down. Two second springs 114 are fixedly installed at the bottom of the long strip 103. The second springs 114 can drive the long strip 103 to fit against the hollow block 101, so that the positioning cone 112 can be better embedded in the inside of the shoulder strap for positioning. The two first springs 107 drive the limiting pin 106 to be embedded in the positioning hole 104, which can position the long strip 103 so that it is flush with the rectangular frame 1. The round block 108 can pull the limiting pin 106 to move.

[0047] Example 3, as Figure 1-4 As shown, the adjustment components include:

[0048] Two round rods 110 are movably embedded in the rectangular groove 109 and can rotate inside the rectangular groove 109. When adjusting the shoulder strap, the positioning cone 112 no longer positions the shoulder strap. Pulling one end of the shoulder strap can adjust it inside the hollow block 101. The round rods 110 can improve the transmission effect and make the shoulder strap move better.

[0049] In this embodiment, the positioning cone 112 no longer positions the shoulder strap. Pulling the shoulder strap allows it to move inside the hollow block 101. The shoulder strap fits against the round rod 110. When the shoulder strap moves, the round rod 110 rotates inside the rectangular groove 109, which can improve the transmission effect, reduce resistance, and make it easier to adjust the shoulder strap.

[0050] Working principle: The long strip plate 103 drives multiple positioning cones 112 to embed into the through hole 111, which can position the shoulder strap embedded in the hollow block 101. The sharp end of the positioning cone 112 is embedded in the shoulder strap to improve the stability of the shoulder strap. The rubber pad 102 further improves the friction of the shoulder strap, making the shoulder strap less likely to slip.

[0051] The handle 105 can be used to press the long strip 103 down. Two second springs 114 are fixedly installed at the bottom of the long strip 103. The second springs 114 can drive the long strip 103 to fit against the hollow block 101, so that the positioning cone 112 can be better embedded in the inside of the strap for positioning. The two first springs 107 drive the limiting pin 106 to be embedded in the positioning hole 104, which can position the long strip 103 so that it is flush with the rectangular frame 1. The round block 108 can be used to pull the limiting pin 106 to move.

[0052] The positioning cone 112 no longer positions the shoulder strap. Pulling the shoulder strap allows it to move inside the hollow block 101. The shoulder strap fits against the round rod 110. When the shoulder strap moves, the round rod 110 rotates inside the rectangular groove 109, which can improve the transmission effect, reduce resistance, and make it easier to adjust the shoulder strap.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
