Description

Technical Field

[0001] This invention relates to the field of cable tie technology, specifically to a cable tie connecting device and its anti-loosening locking method that facilitates quick connection and release, as well as a D-shaped spring for the cable tie connecting device. Background Technology

[0002] Chinese invention patent CN200410100621.3 discloses a high-performance cable tie, comprising an elongated strap and a head extending from one end of the strap. The strap and claw teeth each have convex portions that engage with each other when the strap is inserted through the head. The strap and claw teeth also each have planar portions that engage with each other to prevent the strap from retracting from the head. A concave portion is located on the surface of the claw between the outlet end of the channel and the claw teeth adjacent to it. When the claw pivots in response to the retraction of the strap from the head, this concave portion engages with the convex portion of the opposing strap tooth. This pivoting of the claw is restricted by a heel portion engaging the inner surface of the head. This cable tie can only be tightened in one direction and cannot be retracted in the opposite direction. Objects bound with the cable tie are inconvenient to remove; if removal is necessary, the cable tie is usually cut, and the cable tie cannot be reused.

[0003] Currently, commonly used cable ties are generally used for bundling or connecting objects. A cable tie consists of a long, thin strip with continuously arranged, parallel teeth on one surface. One end of the strip is free, and the other end has a base end for locking and preventing loosening. The cable tie is approximately 1 mm thick, and the distance between adjacent teeth is typically 1 to 2 mm. Plastic cable ties generally can only be tightened in one direction and cannot be loosened, therefore they do not offer bidirectional adjustment of tightness.

[0004] Current devices used for fastening or adjusting the tightness of shoes and clothing generally include shoelaces, elastic bands, or Velcro. Elastic bands are made of rubber and have a limited adjustment range; the elasticity gradually increases as the band is stretched. If the elastic band on pants is too tight, it can cause discomfort and even affect blood circulation, harming health. If the elastic band is too loose, it will not function properly, and the elastic rubber strip is prone to aging and losing its ability to adjust the tightness.

[0005] The relatively thick Velcro strap makes it prone to entanglement or adhesion of fibers and other contaminants, thus reducing its adhesive strength. Existing shoelaces are typically fastened by knots, which are prone to loosening and make it difficult to adjust the tightness of the shoe.

[0006] Existing smartwatches, smart bracelets and other wearable devices generally use traditional watch straps or silicone toothed straps for connection, which is not convenient and usually not easy to adjust the tightness of the strap. Summary of the Invention

[0007] The purpose of this invention is to provide a cable tie connection device and its anti-loosening locking method that are both convenient and quick to connect and quick to release, as well as a D-shaped spring for the cable tie connection device. The cable tie connection device allows for bidirectional adjustment of tightness and is easy to use.

[0008] The objective of this invention is achieved by adopting the following technical solution:

[0009] A cable tie connecting device includes a strap body and a connector, wherein the strap body is elongated and has a first tooth; or, the strap body has a first hole.

[0010] The connector is provided with a strap hole, and a second tooth matching the first tooth or the first hole is provided on one side of the inner surface of the strap hole; an elastic body or shape memory component is provided on the other side of the strap hole opposite to the second tooth.

[0011] When the belt passes through the threading hole, the elastic body or shape memory component pushes the belt to move within the threading hole, so that the first tooth of the belt and the second tooth form an engaging connection; or, so that the first hole of the belt and the second tooth form a snap-fit ​​connection.

[0012] The surface of the connector is provided with a second hole, which is located on the opposite side of the elastic body or shape memory component;

[0013] The operator can push the belt body to move in the opposite direction by using their finger through the second hole; or, by using a special tool to push the belt body to move in the opposite direction through the second hole, thereby disengaging the first tooth of the belt body from the second tooth; or, by disengaging the snap-fit ​​connection between the first hole of the belt body and the second tooth.

[0014] As a preferred embodiment of the present invention, the belt body is configured as a long strip shape with a rectangular cross-section, and at least one side of the belt body is provided with a plurality of first teeth.

[0015] As a preferred embodiment of the present invention, the belt body is configured as a flat strip shape with a rectangular cross-section, and a plurality of first teeth are symmetrically provided on both sides of the belt body;

[0016] The first tooth includes a triangular tooth, a trapezoidal tooth, an arc-shaped tooth, a rectangular tooth, or a cylindrical tooth.

[0017] As a preferred embodiment of the present invention, the special tool includes a button disposed in the second hole of the connector, wherein the upper end of the button is smaller than its lower end, and the bottom area of ​​the lower end of the button is greater than or equal to the area of ​​the second hole.

[0018] The button can move up and down within the second hole.

[0019] As a preferred embodiment of the present invention, the button is composed of a button body and a limiting protrusion provided on the bottom surface of the button body;

[0020] The key body passes through the second hole, the upper end of the key body extends out of the outer surface of the connector, and the strip passes between the bottom surface of the key body and the elastic body or shape memory component;

[0021] Pressing the upper end of the key body can push the belt body to move in a direction perpendicular to the axis of the thread hole.

[0022] As a preferred embodiment of the present invention, the special tool includes a pressing block, the surface of which is provided with protruding teeth that match the second hole. The protruding teeth can extend into the second hole, and the height of the protruding teeth is greater than the depth of the second hole.

[0023] As a preferred embodiment of the present invention, the surface of the connector is provided with a plurality of second holes, and the surface of the pressing block is provided with a plurality of protruding teeth. The protruding teeth of the pressing block can push the belt body to move in a direction perpendicular to the axis of the belt threading hole through the second holes.

[0024] As a preferred embodiment of the present invention, the elastomer includes a plastic, rubber, or metal component with elasticity; the metal component includes a spring or an elastic metal sheet; the shape memory component is made of plastic, rubber, or metal with elastic or flexible properties.

[0025] The end of the belt is provided with a limiting block. After the belt passes through the threading hole, the limiting block can prevent the end of the belt from retracting into the threading hole.

[0026] The limiting block is designed in the shape of a cone, wedge, or arrow with one end larger than the other. The larger end of the limiting block is provided with a groove. Pressing the side of the groove can cause the larger end of the limiting block to undergo elastic deformation. After releasing, the limiting block returns to its initial shape.

[0027] A D-shaped spring for a cable tie connection device, the spring being formed by bending an elastic metal sheet or metal wire into a D-shape. One end of the D-shaped spring with a straight edge is a mounting and fixing end, and the other end with an arc-shaped edge is a telescopic free end. The free end and the fixing end are configured to have a non-contact or non-fixed connection.

[0028] When the D-shaped spring is installed and in operation, the working surface containing the arc-shaped edge receives external force. After being subjected to force, the arc-shaped working surface bends and deforms in a direction perpendicular to the straight edge, and the free end slides in a plane parallel to the straight edge. After the external force is removed, the D-shaped spring returns to its initial shape after installation.

[0029] A method for preventing loosening of a cable tie connection device, wherein after the cable tie passes through the cable hole of the connector, an anti-loosening limiting block is provided in the cable hole;

[0030] Alternatively, after the belt passes through the threading hole of the connector, the belt is bent 180 degrees, and then the end of the belt is inserted into the threading hole.

[0031] The limiting block is designed in the shape of a cone, wedge, or arrow with one end larger than the other. The larger end of the limiting block is provided with a groove. Pressing the side of the groove can cause the larger end of the limiting block to undergo elastic deformation. After releasing, the limiting block returns to its initial shape.

[0032] The beneficial effects of the present invention are as follows: Compared with the prior art, the present invention maintains the connection between the belt and the connector by using an elastic body or shape memory component provided in the belt hole. By pressing or pushing the belt in the opposite direction with the operator's fingers or special tools, the connection between the belt and the connector can be released.

[0033] The present invention can be connected to the belt body and the connector body by either a tooth-to-tooth meshing connection or a hole-to-tooth snap-fit ​​connection, and has a wide range of applications.

[0034] The D-shaped spring of this invention is suitable for places with small working spaces. Its end adopts a non-contact opening method or a non-fixed connection structure. Enlarging the opening or opening the end generates elastic force, which makes it easy to install the D-shaped spring clip in the strap hole of the connector, making installation convenient.

[0035] This invention provides a cable tie connecting device that allows for quick connection and release, as well as bidirectional adjustment of tightness, making it particularly suitable for adjusting a relatively fixed stretchable length. Examples include belts, shoelaces, gloves, hats, helmets, masks, watches, and connecting straps for wearable devices. The appropriate toothed structure between the strap and the connecting body allows for one-handed tightening or loosening, making it extremely convenient to use. Attached Figure Description

Detailed Implementation

[0054] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0055] Example 1

[0056] like Figure 1 and Figure 2As shown, a cable tie connecting device includes a strap body 1 and a connecting body 2. The strap body 1 is elongated and has a first hole 3. The connecting body 2 has a through hole 9, and one side of the inner surface of the through hole 9 has a second tooth 6 that matches the first hole 3. An elastic body is provided on the other side of the through hole 9 opposite to the second tooth 6. The elastic body includes elastic plastic, rubber, or metal components; the metal components include springs and elastic metal sheets. The present invention allows the strap body 1 and the connecting body 2 to be either independently separate or interconnected as a single unit.

[0057] In this embodiment, the elastic body adopts a D-shaped spring 7. The D-shaped spring 7 is formed by bending an elastic metal sheet into a D-shape. One end of the D-shaped spring 7 is embedded in the inner wall of the through hole 9, and the other end is a free end that can slide back and forth on the inner surface of the through hole 9. The surface of the connecting body 2 is provided with a second hole 4, which is located on the opposite side of the D-shaped spring 7.

[0058] When the belt 1 passes through the threading hole 9, the D-shaped spring 7 pushes the belt 1 to move within the threading hole 9, so that the first hole 3 of the belt 1 and the second tooth 6 form a snap-fit ​​connection.

[0059] In this embodiment, the second hole 4 is designed as an ellipse through which the operator's fingers can pass. By pushing the belt body 1 in the opposite direction through the second hole 4 with the fingers, the snap-fit ​​connection between the first hole 3 and the second tooth 6 of the belt body 1 can be released.

[0060] Example 2

[0061] like Figures 3 to 6 As shown, a cable tie connecting device includes a strap body 1 and a connecting body 2. The strap body 1 is a long strip with a rectangular cross-section, and a plurality of first teeth 5 are provided on one side of the strap body 1.

[0062] The connector 2 is provided with a strap hole 9, and a second tooth 6 matching the first tooth 5 is provided on one side of the inner surface of the strap hole 9; an elastic body is provided on the other side of the strap hole 9 opposite to the second tooth 6.

[0063] In this embodiment, the elastic body adopts a D-shaped spring 7. The D-shaped spring 7 is formed by bending an elastic metal sheet into a D-shape. One end of the D-shaped spring 7 is embedded in the inner wall of the through hole 9, and the other end is a free end that can slide back and forth on the inner surface of the through hole 9. The surface of the connecting body 2 is provided with a second hole 4, which is located on the opposite side of the D-shaped spring 7.

[0064] When the belt 1 passes through the threading hole 9, the D-shaped spring 7 pushes the belt 1 to move within the threading hole 9, so that the first tooth 5 of the belt 1 and the second tooth 6 form an engagement connection.

[0065] In this embodiment, the connector 2 is provided with four second holes 4, and a special tool that matches the connector 2 is also provided. In this embodiment, the special tool is a pressing block 13. The surface of the pressing block 13 is provided with four protruding teeth 14 that match the four second holes 4. The protruding teeth 14 can extend into the second holes 4, and the height of the protruding teeth 14 is greater than the depth of the second holes 4.

[0066] When in use, the protruding teeth 14 of the pressing block 13 are passed through the second hole 4 and pushed further, which can push the belt body 1 to move in a direction perpendicular to the axis of the belt hole 9, thereby releasing the meshing connection between the first tooth 5 and the second tooth 6 of the belt body 1.

[0067] Example 3

[0068] like Figures 7 to 10 As shown, a cable tie connecting device includes a cable tie body 1 and a connecting body 2. The cable tie body 1 is a flat strip with a rectangular cross-section. Several first teeth 5 are symmetrically arranged on both sides of the cable tie body 1. The first teeth 5 include triangular teeth, trapezoidal teeth, arc teeth, rectangular teeth or cylindrical teeth.

[0069] The connector 2 is provided with a strap hole 9, and one side of the inner surface of the strap hole 9 is provided with a second tooth 6 that matches the first tooth 5 of the strap 1; a shape memory component 8 is provided on the other side of the strap hole 9 opposite to the second tooth 6, and the bottom surface of the connector 2 is provided with a storage hole 25 for accommodating the shape memory component 8 after bending deformation. The shape memory component 8 is made of plastic, rubber or metal with elastic or flexible properties.

[0070] In this embodiment, both the belt body 1 and the connector 2 are made of plastic, and the shape memory component 8 is also made of plastic. The angle between the shape memory component 8 and the inner surface of the thread hole 9 is less than 90 degrees. The shape memory component 8 can return to its initial angle after being pressed and released by external force.

[0071] When the belt 1 passes through the threading hole 9, the shape memory component 8 pushes the belt 1 to move within the threading hole 9, so that the first tooth 5 of the belt 1 and the second tooth 6 form an engagement connection.

[0072] The connector 2 is provided with a second hole 4 through which the operator's fingers can pass. By pushing the belt 1 in the opposite direction through the second hole 4 with a finger, the meshing connection between the first tooth 5 and the second tooth 6 of the belt 1 can be released.

[0073] In this embodiment, a limiting block 10 is provided at the end of the belt body 1. After the belt body 1 passes through the threading hole 9, the limiting block 10 can prevent the end of the belt body 1 from retracting into the threading hole 9. The limiting block 10 is designed as an arrow shape with one end larger than the other end; the larger end of the limiting block 10 is provided with a groove 11. Pressing the side of the groove 11 can cause the larger end of the limiting block 10 to undergo elastic deformation. After releasing, the limiting block 10 returns to its initial shape.

[0074] Referring to Embodiment 1 or Embodiment 2 of the present invention, this embodiment can also employ different implementation methods. For example, the shape memory component 8 can be replaced with the D-shaped spring described above. The operator can press the side of the groove 11 of the limiting block 10 with their fingers to retract the limiting block 10 and the end of the strap 1 into the threading hole 9. This implementation is particularly suitable for use as shoelaces; and as connecting straps for gloves, hats, helmets, or wearable devices. It can also be used for binding and securing special objects. When the strap is released, the present invention prevents the strap from suddenly and completely detaching from the connecting body, thereby avoiding the object from scattering or falling off, and improving safety and reliability.

[0075] Example 4

[0076] like Figures 11 to 16 As shown, a cable tie connecting device includes a cable tie body 1 and a connecting body 2. The cable tie body 1 is a flat strip with a rectangular cross-section. Several first teeth 5 are symmetrically arranged on both sides of the cable tie body 1. The first teeth 5 include triangular teeth, trapezoidal teeth, arc teeth, rectangular teeth or cylindrical teeth.

[0077] The connector 2 is provided with a strap hole 9, and a second tooth 6 that matches the first tooth 5 of the strap body 1 is provided on one side of the inner surface of the strap hole 9; an elastic body is provided on the other side of the strap hole 9 opposite to the second tooth 6.

[0078] In this embodiment, the elastic body adopts a D-shaped spring 7, which is formed by bending an elastic metal sheet into a D-shaped structure; the surface of the connecting body 2 is provided with a second hole 4, which is located on the opposite side of the D-shaped spring 7; a special tool for pushing the belt body 1 to move is provided in the second hole 4.

[0079] When the belt 1 passes through the threading hole 9, the D-shaped spring 7 pushes the belt 1 to move within the threading hole 9, so that the first tooth 5 of the belt 1 and the second tooth 6 form an engagement connection.

[0080] In this embodiment, the special tool is a button 12 located in the second hole 4 of the connector. The upper end of the button 12 is smaller than its lower end, and the bottom area of ​​the lower end of the button 12 is greater than or equal to the area of ​​the second hole 4. The button 12 can move up and down within the second hole 4.

[0081] The button 12 consists of a button body and a limiting protrusion on the bottom surface of the button body. The button body of the button 12 passes through the second hole 4, and the upper end of the button body extends out of the outer surface of the connecting body 2. The belt 1 passes between the bottom surface of the button body and the D-shaped spring 7. Pressing the upper end of the button body can push the belt 1 to move in a direction perpendicular to the axis of the belt hole 9, thereby releasing the meshing connection between the first tooth 5 and the second tooth 6 of the belt 1.

[0082] In this embodiment, the connecting body 2 consists of an upper cover 21 and a base plate 22. The surface of the base plate 22 is provided with a spring seat 23 and a sliding groove 24. Both the spring seat 23 and the sliding groove 24 are designed with concave structures. One end of the D-shaped spring 7 is embedded in the spring seat 23 of the base plate 22, and the other end is a free end that can slide back and forth in the sliding groove 24. The D-shaped spring 7 is provided with an arc-shaped working surface. The upper cover 21 and the base plate 22 of the connecting body 2 are preferably connected in a detachable manner, such as a snap-fit ​​connection, a screw connection, or a bolt and nut connection; a welding or adhesive fixing connection can also be used.

[0083] Example 5

[0084] like Figure 17 As shown, a D-shaped spring for a cable tie connection device is provided. The spring is formed by bending an elastic metal sheet or metal wire into a D-shape. One end of the D-shaped spring 7 with a straight edge 71 is a fixed end for installation, and the other end with an arc edge 72 is a free end for extension and retraction. The free end and the fixed end are configured to be non-contact or non-fixed connected.

[0085] In this embodiment, the end of the D-shaped spring 7 adopts a non-contact opening method. Enlarging the opening will generate elastic force, which makes it easy to install the D-shaped spring 7 into the spring seat of the cable tie connection device.

[0086] When the D-shaped spring 7 is installed and in operation, the working surface where the arc-shaped edge 72 is located is used to receive external force. After the arc-shaped working surface is subjected to force, it bends and deforms in the direction perpendicular to the straight edge 71, and the free end slides in the plane parallel to the straight edge 71. After the external force is removed, the D-shaped spring 7 returns to its initial shape after installation.

[0087] Example 6

[0088] A method for preventing loosening and locking a cable tie connection device, referring to any one of the embodiments one to four of the present invention, wherein after the cable tie passes through the through hole of the connector, an anti-loosening limiting block is provided in the through hole; or, after the cable tie passes through the through hole of the connector, the cable tie is bent 180 degrees, and then the end of the cable tie is inserted into the through hole, thereby forming an anti-loosening locking structure between the cable tie and the connector, making the connection more secure.

[0089] In this embodiment, the limiting block is designed as a wedge-shaped structure or arrowhead shape with one end larger than the other. The larger end of the limiting block has a groove. Pressing the side of the groove causes the larger end of the limiting block to elastically deform. After releasing, the limiting block returns to its initial shape. The limiting block of this invention can be an independent component or it can be located at the end of the belt body.

[0090] The above embodiments are merely illustrative of the concept and technical features of the present invention, and are intended to enable those skilled in the art to understand the technical solutions and implementation methods of the invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent substitutions or changes made according to the technical solutions of the present invention should be covered within the scope of protection of the present invention.
