Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of logistics equipment, and relates to a woven tape binding device. BACKGROUND

[0002] In the field of cargo transportation, the performance of a binding device directly affects the safety and reliability of cargo transportation. In existing binding devices, elastic buckles are used to connect and pre-tighten the woven tape. Therefore, the applicant previously developed an elastic buckle in a binding device (application number: 201410010723.X), which comprises a buckle frame, a pressing plate and a spring. The pressing plate is in the form of a plate, and the middle part of the pressing plate is hingedly connected to the upper part of the buckle frame. The inner end of the pressing plate has a clamping part, and the outer end of the pressing plate has a pressing part for an operator to press. The spring is located between the pressing plate and the buckle frame, and under the action of the spring force, the clamping part can abut against the buckle frame. After an external force is applied to press the pressing part, the clamping part can be separated from the buckle frame, and a passage is formed between the two for the tape to pass through.

[0003] In actual use, the product has some deficiencies. The pressing plate of the elastic buckle is installed in an exposed state. Although the structure is simple and the installation is convenient, during cargo transportation, the cargo may move due to bumps, extrusion and other situations during transportation, and then collide with the exposed pressing plate from multiple directions. At this time, the pressing plate and related parts are prone to displacement or deformation, especially the pin shaft used to realize the hinged installation of the pressing plate, which is more prone to bending. As a key component connecting the pressing plate and the buckle frame, once the pin shaft is deformed, the hinged connection between the pressing plate and the buckle frame will be abnormal, causing the pressing plate to loosen or fail to rotate normally, thereby affecting the clamping and releasing functions of the elastic buckle on the tape, and in severe cases, the binding device may not work normally. Therefore, the product still has the problem of insufficient use reliability. SUMMARY

[0004] The present application aims to solve the above-mentioned problems existing in the prior art, and provides a woven tape binding device. The present application solves the problem of insufficient use reliability of the existing woven tape binding device.

[0005] The purpose of the present application can be achieved by the following technical solutions: a webbing binder comprising a body with a toothed surface on the inner wall and a belt pressing head hingedly connected to the middle part of the body, and an elastic element arranged in the body and capable of driving the front end of the belt pressing head to swing downward and abut against the toothed surface, characterized in that the webbing binder further comprises a pressing element, the pressing element and the belt pressing head are arranged in the body, the body has a top wall above the belt pressing head and an installation opening is formed in the top wall and vertically opposite to the rear end of the belt pressing head, the top of the pressing element is vertically slidingly inserted into the installation opening and the pressing element does not protrude out of the body, the bottom of the pressing element is L-shaped so as to form a horizontal strip-shaped gap on the front side wall of the pressing element, and the rear end of the belt pressing head has a columnar part parallel to the rotation center line of the belt pressing head, the columnar part is slidingly arranged in the strip-shaped gap.

[0006] The webbing binder is additionally provided with the pressing element, the body has the top wall above the belt pressing head, the installation opening vertically opposite to the rear end of the belt pressing head is formed in the top wall, the top of the pressing element is vertically slidingly inserted into the installation opening, and the pressing element is pressed downward. At this time, the bottom of the pressing element is L-shaped, so that the horizontal strip-shaped gap is formed on the front side wall of the pressing element, and the rear end of the belt pressing head is designed to have the columnar part parallel to the rotation center line of the belt pressing head, and the columnar part is slidingly arranged in the strip-shaped gap. Through the design, when the pressing element is pressed downward, the columnar part will slide in the strip-shaped gap while keeping parallel to the rotation center line, so as to stably swing the rear end of the belt pressing head downward. Therefore, the webbing binder breaks through the conventional technology of directly pressing the exposed belt pressing head, and realizes the swinging of the belt pressing head in the body by the cooperation between the columnar part of the belt pressing head and the strip-shaped gap of the pressing element. In the structure, since the belt pressing head and the pressing element are arranged in the body with the top wall, and the pressing element does not protrude out of the body, even if the webbing binder is impacted by surrounding goods during transportation, the body can effectively protect the internal components such as the belt pressing head and the pressing element, especially avoid the phenomenon that the belt pressing head as the core component of the webbing binder is loose or cannot rotate normally, and improve the use reliability of the product.

[0007] In the above-mentioned webbing binder, the pressing element is formed by extending two L-shaped extension parts from the bottom surface of a rectangular block-shaped member, each extension part and the bottom surface of the rectangular block-shaped member form the strip-shaped gap, one end of the columnar part is slidingly arranged in one of the strip-shaped gaps and the other end is slidingly arranged in the other strip-shaped gap.

[0008] The two L-shaped extension parts are formed on the bottom surface of the rectangular block-shaped member, which is not only convenient to manufacture, but also provides reliable sliding paths for the cylindrical part at the rear end of the pressing head, ensuring that the cylindrical part can be accurately inserted into the strip-shaped notch during assembly, so that the pressing head is easy to assemble with the pressing member. More importantly, the two ends of the cylindrical part are respectively in sliding cooperation with the two strip-shaped notches, so that when the pressing member moves up and down, the cylindrical part can slide accurately along the strip-shaped notch, avoiding deviation or shaking, so that the pressing member can more stably drive the pressing head to swing, improving the use reliability of the product.

[0009] In the above woven tape binder, the pressing head is hinged between the left and right side walls of the body through a pin shaft, the middle part of the pressing head is hollow and the cylindrical part is integrally formed between the rear ends of the left and right side walls of the pressing head, the two extension parts extend into the left and right side walls of the pressing head, and the elastic member is a torsion spring located in the hollow part of the middle part of the pressing head and sleeved on the pin shaft, one end of the torsion spring abuts against the lower side wall of the cylindrical part, and the other end abuts against the inner wall of the body. The hollow design of the middle part of the pressing head not only provides space for the two extension parts of the pressing member, but also enables the cylindrical part of the pressing head to be smoothly inserted into the strip-shaped notch, thereby achieving the swinging of the pressing head in the mounting cavity by the pressing member, effectively protecting the pressing head and improving the use reliability of the woven tape binder. At the same time, the hollow area also provides a mounting position for the torsion spring, which ingeniously utilizes the hollow area to enable the torsion spring to be conveniently placed in the body and adjusted in angle after the pressing head and the pressing member are installed in place, so that the pin shaft can smoothly pass through the pressing head and the torsion spring, thereby ensuring the convenience of the entire assembly process.

[0010] In the above woven tape binder, the tooth-shaped surface is located on the front side of the pressing head and is inclined upward, and an arc-shaped plate-shaped pressing belt is integrally formed between the front ends of the left and right side walls of the pressing head, the front end surface of the pressing belt abuts against the tooth-shaped surface, and the front end surface is an outward convex surface with a plurality of teeth. In this design, the top of the body has a belt passing port above the tooth-shaped surface, and the tooth-shaped surface is inclined upward, thereby cooperating with the front end of the pressing head to form a front-to-back direction clamping woven tape mode. During the process of passing through the woven tape, the direction of the woven tape passing in and out is almost on the same straight line, without a large turning of the woven tape passing through the belt passing channel as in the background art, so that after the pressing head is embeddedly installed, the woven tape passing device is still convenient and fast, thereby improving the convenience of product use. At the same time, since the tooth-shaped surface is inclined upward, the front end of the pressing head always has a tendency to swing downward when the woven tape is stressed during the binding process, so that the pressing head will bite the woven tape tighter and tighter, forming a self-locking mechanism to avoid the woven tape from loosening.

[0011] In the above-mentioned woven tape binder, a strip-shaped tape passing portion is integrally formed between the front ends of the left and right side walls of the body, the body has a tape passing opening above the tape passing portion, the thickness dimension of the tape passing portion gradually increases from top to bottom, and the inner side wall of the tape passing portion is the tooth-shaped surface.

[0012] The thickness dimension of the tape passing portion gradually increases from top to bottom, so that the inner side wall of the tape passing portion directly forms an upwardly inclined tooth-shaped surface. In this design, the tape passing portion is integrally formed with the body, which not only has high structural strength, but also improves the use reliability of the woven tape binder, avoids the need for additional tooth-shaped surface components, reduces the number of parts, simplifies the assembly steps, and makes the product assembly convenient. The tape passing opening is located above the tape passing portion, so that the user can more intuitively see the passing path of the woven tape when operating the woven tape binder, reducing the operation difficulty.

[0013] In the above-mentioned woven tape binder, the front side edge of the mounting opening extends downward to form a plate-shaped guide portion, a rear end wall parallel to the guide portion is integrally formed between the left and right side walls of the body, and the front and rear side walls of the top of the pressing piece are respectively in sliding fit with the guide portion and the rear end wall. When the pressing piece is installed, the guide portion and the rear end wall provide a clear sliding path for the pressing piece, so that the pressing piece can be smoothly inserted into the body. At the same time, after the product assembly is completed, the guide portion and the rear end wall provide stable guidance for the up and down movement of the pressing piece, so that the process of pressing the pressing piece is smooth and stable, ensuring that the woven tape binder can accurately and stably engage and release the woven tape.

[0014] In the above-mentioned woven tape binder, the bottom edge of the rear end wall of the body has a protruding limiting protrusion, the limiting protrusion is located below the pressing piece, and the pressing piece can abut against the limiting protrusion after moving downward. When the pressing piece moves downward to the limit position, it can abut against the limiting protrusion, thereby limiting the stroke of the pressing piece, so that the product operation is convenient.

[0015] In the above-mentioned woven tape binder, the limiting protrusion is in the shape of a U-shaped plate and has a protruding column on the upper side, the two ends of the torsion spring are in the shape of L, and the other end of the torsion spring abuts against the upper side of the limiting protrusion and extends between the protruding column and the rear end wall. This structure makes the limiting protrusion have a dual function, which can not only limit the stroke of the downward movement of the pressing piece, but also serve as a positioning function for the torsion spring. Specifically, since the limiting protrusion is in the shape of a U-shaped plate and has a protruding column on the upper side, and the other end of the torsion spring is in the shape of L and extends between the protruding column and the rear end wall, this structure makes it possible to position the end of the torsion spring during the installation of the torsion spring to avoid loosening. When the pin shaft needs to be inserted, one end of the torsion spring abuts against the columnar portion, and the other end is positioned on the limiting protrusion. This design can facilitate the adjustment of the angular position of the torsion spring, thereby ensuring that the pin shaft can smoothly pass through the torsion spring, making the product assembly more convenient.

[0016] In the above woven tape bundler, the cross section of the columnar portion is circular, the strip-shaped notch is horizontally arranged in the front-rear direction, and the width dimension of the strip-shaped notch is matched with the outer diameter dimension of the columnar portion. The strip-shaped notch is matched with the circular cross section of the columnar portion, which can ensure smooth sliding of the columnar portion in the strip-shaped notch, so that the pressing member can accurately and stably drive the pressing head to swing. At the same time, since the strip-shaped notch is horizontally arranged in the front-rear direction, the columnar portion can be smoothly inserted into the strip-shaped notch during product assembly, making the assembly process more intuitive and convenient.

[0017] In the above woven tape bundler, the rear ends of the left and right side walls of the body are integrally formed with a tape winding portion, which is located outside the rear end wall and is cylindrical. This design can more intuitively and conveniently connect the woven tape on the tape winding portion. At the same time, since the tape winding portion is integrally formed with the body, not only the number of parts is reduced, but also the tape winding portion has high structural strength, avoiding deformation or fracture of the tape winding portion leading to bundling failure, ensuring the use reliability of the product.

[0018] Compared with the prior art, the woven tape bundler has the following advantages:

[0019] 1. The woven tape bundler is improved in structure and shape of the pressing head, the pressing member and the body. Although the number of parts is increased compared with the prior art, only one pin shaft is needed to assemble the related parts into the body, so that the woven tape bundler has the advantage of convenient assembly.

[0020] 2. The top of the body is in the form of a hollow plate. After the pressing head is installed in the body, a "hidden" installation structure is formed. Even if the woven tape bundler is impacted by surrounding goods during transportation, the body can avoid direct impact on the pressing head, thereby protecting the pressing head and avoiding the phenomenon of looseness or failure of the pressing head as the core component of the woven tape pressing. The product can always stably engage and release the woven tape, so that the woven tape bundler has the advantage of high use reliability. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0032] The following is a specific embodiment of the present application and further describes the technical solution of the present application in combination with the accompanying drawings, but the present application is not limited to this embodiment.

[0033] As shown in Figure 1 and Figure 2 , the woven tape binder comprises a pressing member 5, a body 1 with a toothed surface 11 on the inner wall and a pressing head 2 arranged in the body 1, the body 1 further has a top wall above the pressing head 2, and the body 1 is internally formed with an installation cavity 1a with an opening downward, so that the pressing head 2 can be put into the body 1 through the opening. During the process of binding the goods, usually the bottom of the body 1 is attached to the surface of the goods (such as glass, paperboard, etc.), so that the opening of the installation cavity 1a is blocked by the goods. The pin shaft 3 passing through the middle part of the pressing head 2 is fixedly connected between the left and right side walls of the body 1, and the body 1 is further provided with an elastic member 4 capable of driving the front end of the pressing head 2 to swing downward and abut against the toothed surface 11. Specifically, the body 1 is further integrally formed with a strip-shaped tape passing part 14 between the front ends of the left and right side walls, the thickness dimension of the tape passing part 14 gradually increases from top to bottom, and the inner side wall of the tape passing part 14 forms an inclined toothed surface 11 upward.

[0034] In combination with Figure 2 , Figure 3 and Figure 4As shown, the top wall of the body 1 is in the shape of a hollow plate, and the hollow parts form a mounting opening 12 opposite to the rear end of the pressing head 2 and a belt passing opening 13 above the front end of the pressing head 2. The top edge of the belt passing part 14 is the lower side edge of the belt passing opening 13. The pressing member 5 is inserted into the body 1 through the mounting opening 12. The rear ends of the left and right side walls of the body 1 are integrally formed with a belt winding part 18 in the shape of a cylinder and located outside the rear end wall 16. The front side edge of the mounting opening 12 extends downward to form a guide part 15 in the shape of a plate. The guide part 15 is spaced from the left and right side walls of the body 1 to avoid interference with the left and right side walls of the pressing head 2 when the pressing head 2 swings. The pressing member 5 is also arranged in the body 1 and does not protrude from the body 1. In order to improve the guiding effect of the pressing member 5, the top of the pressing member 5 is in the shape of a block, and the mounting opening 12 is rectangular and has a size matching the size of the top of the pressing member 5. Meanwhile, the left and right side walls of the body 1 are integrally formed with a rear end wall 16 parallel to the guide part 15. The front and rear side walls of the top of the pressing member 5 are in sliding fit with the guide part 15 and the rear end wall 16, respectively.

[0035] As shown in Figure 2 and Figure 5 , the bottom of the pressing member 5 is in the shape of an L to form a horizontal strip-shaped gap 51 on the front side wall of the pressing member 5. The rear end of the pressing head 2 has a cylindrical part 21 parallel to the pin shaft 3, which is arranged in sliding fit in the strip-shaped gap 51. Specifically, the pressing member 5 is formed by extending two L-shaped extension parts 52 from the bottom surface of a rectangular block-shaped member. Each extension part 52 forms a strip-shaped gap 51 with the bottom surface of the rectangular block-shaped member. The two extension parts 52 of the pressing member 5 extend into the left and right side walls of the pressing head 2, and the two ends of the cylindrical part 21 are in sliding fit with one strip-shaped gap 51, respectively. This structure enables the cylindrical part 21 to slide accurately along the strip-shaped gap 51 when the pressing member 5 moves up and down, avoiding deflection or shaking, so that the pressing member 5 can more stably drive the pressing head 2 to swing, improving the use reliability of the product.

[0036] In combination with Figure 2 , Figure 6 and Figure 7As shown, the middle part of the pressing head 2 is hollow, and a columnar part 21 is integrally formed between the rear ends of the left and right side walls of the pressing head 2. An arc-shaped plate-shaped pressing strip 22 is integrally formed between the front ends of the left and right side walls of the pressing head 2. The front end face of the pressing strip 22 abuts against the toothed surface 11, and the front end face is an outward convex surface with a plurality of teeth. The cross section of the columnar part 21 is circular, and the strip-shaped notch 51 is horizontally arranged in the front-rear direction. The width dimension of the strip-shaped notch 51 is matched with the outer diameter dimension of the columnar part 21, so that the pressing piece 5 can accurately and stably drive the pressing head 2 to swing. The elastic piece 4 is a torsion spring located in the hollow part of the middle part of the pressing head 2 and sleeved on the pin shaft 3. One end of the torsion spring abuts against the lower side wall of the columnar part 21, and the other end abuts against the inner wall of the body 1.

[0037] As shown in Figure 7 and Figure 8 , the bottom edge of the rear end wall 16 of the body 1 has a protruding limiting protrusion 17 located below the pressing piece 5, and the pressing piece 5 can abut against the limiting protrusion 17 after moving downward. Specifically, the limiting protrusion 17 is in the shape of a U-shaped plate, and a convex column 171 is integrally formed on the upper side face. The two ends of the torsion spring are in the shape of L. The other end of the torsion spring abuts against the upper side face of the limiting protrusion 17 and extends between the convex column 171 and the rear end wall 16.

[0038] Compared with the conventional structure of the open installation in the background art, the number of components of the present woven tape binding device is increased due to the addition of the pressing piece 5, and the embedded installation design is adopted. If better assembly convenience is to be achieved, the design rationality of the assembly structure is crucial, and it also has great technical difficulty. Therefore, the applicant innovatively designs the shapes of the pressing piece 5, the pressing head 2 and the body 1. Through the linkage cooperation between the columnar part 21 of the pressing head 2 and the strip-shaped notch 51 of the pressing piece 5, the pressing piece 5 is not only driven to swing when moving downward, but also can be limited from being pulled out of the installation opening 12 by the pressing head 2. This linkage cooperation structure does not need to additionally install components for limiting the pressing piece 5 from being pulled out of the installation opening 12, nor does it need to additionally install components for linkage between the pressing head 2 and the pressing piece 5. Therefore, through the comprehensive improvement of the structures and shapes of the pressing head 2, the pressing piece 5 and the body 1, although the number of components is increased compared with the prior art, only one pin shaft 3 is needed to assemble the related components into the body 1, so that the purpose of convenient assembly is achieved.

[0039] Specifically, the order of the components assembled into the body 1 is as follows: the pressing piece 5, the pressing head 2, the elastic piece 4 and the pin shaft 3. Specifically, the pressing piece 5 is first inserted into the body 1 through the installation opening 12, then the pressing head 2 is placed into the body 1 from the bottom of the body 1 and kept in a state close to the vertical direction, so as to facilitate the smooth insertion of the columnar portion 21 at the rear end of the pressing head 2 into the strip-shaped gap 51, and then the posture of the pressing head 2 is adjusted so that the whole pressing head 2 enters into the body 1. Then, the elastic piece 4, i.e. the torsion spring, is placed into the body 1 from the bottom of the body 1, and one end of the torsion spring abuts against the columnar portion 21 of the pressing head 2 and the other end abuts against the limiting protrusion 17, and the posture of the torsion spring and the pressing head 2 is adjusted, and finally the pin shaft 3 is inserted, and the assembly is completed. The pin shaft 3 passes through the installation holes 23 on the left and right side walls of the pressing head 2, so that the pressing head 2 can rotate around the pin shaft 3, and the end of the pin shaft 3 is fixedly connected into the connecting hole 19 of the body 1. The pin shaft 3 can be fixedly connected with the connecting hole 19 of the body 1 by means of tight fit or welding.

[0040] As shown in Figure 9 and Figure 10 , a piece of braid has been connected on the braid passing portion 18 at the rear end of the body 1 of the braid binder. When the braid binder is used, the pressing piece 5 is first pressed downward to move downward, so that the front end of the pressing head 2 is raised upward to be separated from the toothed surface 11 to form a braid passing channel. Then, another piece of braid is passed into the body 1 from the opening at the bottom of the body 1, and then passed out of the body 1 through the braid passing channel and the braid passing opening 13 in sequence, and the braid passed out of the braid passing opening 13 is pulled tightly, and then the pressing piece 5 is released, and the front end of the pressing head 2 is pressed against the braid under the action of the elastic piece 4 to prevent the braid from being loosened.

[0041] The specific embodiments described herein merely exemplify the spirit of the present application. Those skilled in the art to which the present application pertains can make various modifications or supplements to the described specific embodiments or replace them with similar ways, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.

[0042] Although the terms such as 1, body; 11, toothed surface; 12, installation opening; 13, braid passing opening; 14, braid passing portion; 15, guide portion; 16, rear end wall; 17, limiting protrusion; 171, protruding column; 18, braid passing portion; 19, connecting hole; 2, pressing head; 21, columnar portion; 22, pressing portion; 23, installation hole; 3, pin shaft; 4, elastic piece; 5, pressing piece; 51, strip-shaped gap; 52, extension portion, etc. are used more frequently herein, but the possibility of using other terms is not excluded.
