Description

Technical Field

[0001] This application relates to a snap fastener for securing a strip, and more particularly to a snap fastener designed to prevent accidental contact. Background Technology

[0002] In outdoor activities, transportation, and packaging, it is often necessary to use straps (such as webbing, plastic straps, etc.) for binding or securing. Existing snap fasteners, due to their long handles, are prone to accidental activation, causing the pressure teeth to flip upwards and loosen the strap, creating a safety hazard. Therefore, a snap fastener that prevents accidental activation and improves safety is needed. Utility Model Content

[0003] This application provides a buckle designed to prevent accidental activation, comprising a base, pressure teeth, and a handle. The pressure teeth are hinged to the base, and the handle is connected to the pressure teeth. When the pressure teeth are depressed, they lock the strap passing between the base and the pressure teeth. When the handle is pressed, the pressure teeth are depressed around the hinge axis, releasing the strap. The handle can be translated relative to the pressure teeth to shorten the lever arm, preventing accidental activation of the handle from causing the pressure teeth to depress and accidentally release the strap.

[0004] The pressure tooth and the base are hinged by a pin and rivet, and a coil spring is fitted on the pin and rivet. The coil spring connects the base and the pressure tooth, so that the pressure tooth automatically flips down under the action of the spring force.

[0005] The handle is plate-shaped, with its two sides and the inner surface of the pressure teeth slidingly connected to each other, and it is stacked on top of the pressure teeth when the lever arm is shortened.

[0006] The specific connection method between the handle and the pressure tooth is as follows: there are flanges on both sides of the lower part of the plate-shaped handle, which are embedded into two side grooves corresponding to the recessed surface of the pressure tooth. The side grooves do not penetrate the surface of the pressure tooth to prevent the plate-shaped handle from detaching from the pressure tooth when it moves horizontally.

[0007] The surface of the flat handle has horizontal grooves, or it can be sanded to increase the friction when the handle is moved and unfolded by hand, making it easier to press the surface of the handle and move the handle relative to the pressure teeth to the maximum lever arm.

[0008] An embedded handle structure can also be adopted, with a cavity inside the pressure teeth that fits the shape of the handle. When the handle is in the shortened lever arm state, most of it is embedded in the cavity of the pressure teeth.

[0009] The opening of the pressure tooth cavity is narrower than the inside. The handle is inserted into the head with outward protrusions on both sides and slots on both sides. This makes it easier to insert the handle into the pressure tooth cavity when it is squeezed and deformed during installation. After installation, the protrusions return to their original shape to prevent the handle from falling out.

[0010] The handle has a groove at the end of its surface. When used in a narrow space, if you cannot reach in to slide the handle out, you can use a thin, rigid pry bar with a hook to reach in, hook the handle in the groove, and stretch the handle out. If the space is still not enough to press the handle by hand after it is out, you can use the pry bar to hook the handle in the groove and pry it out.

[0011] Beneficial effects: The anti-accidental pressure buckle of this application, through the special design of the handle, effectively prevents the pressure teeth from accidentally flipping upwards due to accidental contact, thus improving safety during use. The sliding design of the handle minimizes the lever arm in the locked state and minimizes the effort required for pressing in the stretched state. The horizontal groove design on the handle surface increases the friction when sliding the handle by hand, further improving ease of operation. In addition, the sliding design of the handle makes the environmental space requirements for using this anti-accidental pressure buckle extremely low. In particular, the grooves on the handle surface further reduce the space requirements, making it convenient for use in confined spaces. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.

[0022] Example 1

[0023] The handle to prevent accidental pressing of the buckle is plate-shaped, and when the lever arm is shortened, the handle is stacked on top of the pressing teeth.

[0024] like Figure 1 As shown, the anti-accidental pressure buckle includes a base 1, pressure teeth 2, and a handle 3.

[0025] like Figure 2 As shown, the plate-shaped handle is moved to its maximum lever arm position for easy pressing.

[0026] like Figure 3 As shown, when the lever arm is shortened, the plate handle 3 is stacked on top of the pressure tooth 2.

[0027] The pressure tooth 2 is hinged to the base 1, and the handle 3 is connected to the pressure tooth 2. The pressure tooth 2 and the base 1 are hinged by a shaft pin rivet 4. The coil spring 5 is sleeved on the shaft pin rivet 4. A protrusion 51 is provided on the inner side of the base 1. One end of the coil spring 5 leans against the protrusion 51 and is connected to the base 1. The other end of the coil spring 5 is connected to the pressure tooth 2. Under the elastic force of the coil spring 5, the pressure tooth 2 automatically flips down.

[0028] like Figure 4 As shown, the strip 11 passes between the base 1 and the pressure tooth 2 when the pressure tooth 2 flips up.

[0029] like Figure 5 As shown, when the pressure tooth 2 flips down, it locks the strip 11 that passes between the base 1 and the pressure tooth 2.

[0030] When the handle 3 is pressed, the pressure tooth 2 flips up around the hinge shaft 4, releasing the strip 11.

[0031] The handle 3 is plate-shaped, with the protrusions on both sides of the lower edge and the recessed surface of the pressure teeth 2 slidingly connected.

[0032] The specific connection method is as follows: there are flanges 6 on both sides of the lower part of the plate handle 3, which are embedded into the side grooves 8 on the corresponding sides of the recessed surface 7 of the pressure tooth 2. The side grooves 8 do not penetrate the surface of the pressure tooth 2 to prevent the plate handle 3 from detaching from the pressure tooth 2 when it moves horizontally.

[0033] In this embodiment, when the lever arm is at its maximum, the length of the overlapping part of the plate handle and the pressure tooth is less than 1 / 2 of the total length of the plate handle. As long as it can achieve the effect of convenient pressing, the size ratio of other overlapping parts relative to the total length of the handle is also optional.

[0034] The flange and side groove are sized to fit each other, so that they do not slip without external force due to a loose fit, nor do they have a lot of resistance when moving by hand due to a tight fit. If necessary, the sliding contact surface can be sanded to increase resistance.

[0035] The surface of the handle 3 has horizontal lines 9, or it can be frosted to increase the friction when the handle 3 is moved horizontally and unfolded by hand.

[0036] The handle 3 has a groove 10 at the end of its surface, which facilitates the hooking of a narrow, rigid, long tool with a hook to assist in stretching and pressing when used in confined spaces.

[0037] Example 2

[0038] The handle designed to prevent accidental activation of the buckle is mostly embedded inside the pressure teeth when the lever arm is shortened.

[0039] like Figure 6 As shown, the pressure tooth 2 has a cavity 12 inside that fits the shape of the handle 3. When the handle 3 is in the shortened lever arm state, most of it is embedded in the cavity 12 of the pressure tooth 2.

[0040] In this embodiment, the length of the embedded part is no less than 2 / 3 of the total length, but other length ratios are also optional as long as the effect of preventing accidental touches can be achieved.

[0041] The opening of the cavity 12 of the pressure tooth 2 is narrower than the inside. The head of the insertion end 13 of the handle 3 has an outward protrusion 14 and slots 15 on both sides. When installed, the handle 3 is squeezed and deformed to facilitate insertion into the cavity 12 of the pressure tooth 2. After insertion, the protrusion 14 returns to its original shape to prevent the handle 3 from falling out.

[0042] The cavity 12 is sized to fit the insert end 13 and protrusion 14 of the handle 3. The fit is neither too loose, causing it to slip without external force, nor too tight, causing great resistance when moving by hand. If necessary, the sliding contact surface can be sanded to increase resistance.

[0043] The parts that are the same as those in Example 2 and Example 1 will not be repeated here.

[0044] The above description is merely a typical embodiment of this application and is not intended to limit this application in any way. Any modifications or equivalent changes made based on the technical essence of this application shall still fall within the scope of protection claimed by this application.
