Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of logistics transportation instrument, and relates to a crowbar type binding device. BACKGROUND

[0002] In the transportation process, goods often need to be bound to prevent falling or moving. The binding device is a device that can firmly bind the goods on the car, which has been widely used in the field of logistics.

[0003] The conventional binding device has a handle for holding by hand. By operating the handle of the binding device, the ratchet is driven to move, so that the binding belt is gradually wound on the reel of the binding device, thereby tightening the goods on the truck to achieve the purpose of safe transportation. For example, a binding device disclosed in the patent document (application number: 200910144084.5) includes a body assembly, a handle, a pull handle, and a shaft. The handle and the body assembly are hinged by the shaft. The shaft is provided with a ratchet. The pull handle is slidably connected to the handle. The end of the pull handle can be inserted between the ratchet teeth of the ratchet. The binding device also includes a lock. When the lock is locked, the lock can prevent the pull handle from sliding. The existing handle type binding device has the following disadvantages in actual use:

[0004] 1. In the handle type binding device, the handle is a mechanical component for applying force, so it needs sufficient lever length to apply sufficient force for binding operation. Therefore, the size of the handle of the binding device cannot be too small, which will result in a large overall size of the binding device, which is not convenient to carry or operate. On the other hand, since the length of the lever is always limited when operating the handle, the handle type binding device has the disadvantage of laborious operation when pre-tightening the binding belt, especially for heavy duty binding devices used to fix heavy goods, when the required pre-tightening force is large.

[0005] 2. For the handle type binding device, the handle of the binding device usually includes two oppositely arranged side pieces. The tail ends of the two side pieces need to be connected to the shaft tube of the handle. A handle sleeve is usually provided outside the shaft tube or plastic coated. This makes the handle structure of the binding device relatively complex, so a more complex process flow and higher material cost are required, which leads to the problem of high manufacturing cost of the handle type binding device.

[0006] At present, in order to solve the problems of large product size and laborious operation of the existing binding device, the conventional technical means adopted is:

[0007] 1. Increasing the handle length to extend the lever length achieves the purpose of saving effort. However, when considering product size design, conventional distributors also employ a telescopic handle structure. During the binding operation, the handle is pulled outwards to make it longer, thus reducing the effort required for binding. When the handle is retracted inwards, the product size remains relatively small. For example, patent literature discloses a "telescopic handle car safety tensioning device (application number: 201220226589.3)";

[0008] 2. Larger ratchet wheels typically provide greater torque, allowing the force applied to the handle to be more effectively converted into binding force. Therefore, some binding devices now use ratchet diameter increases to make operation easier. Summary of the Invention

[0009] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a pry bar type binding device. This invention solves the problems of existing binding devices being large in size, having high manufacturing costs, and being laborious to operate.

[0010] The purpose of this utility model can be achieved through the following technical solution: a pry bar type binding device, including a main support, a reel connected to the main support, and a take-up support that can drive the reel to rotate when swinging, characterized in that the take-up support is U-shaped and the open end of the take-up support is rotatably connected to the reel, and the closed end of the take-up support is fixedly connected to a pry bar sleeve, one end of the pry bar sleeve facing the reel and the pry bar sleeve being perpendicular to the reel.

[0011] Compared with the conventional handle type binding device, the pry bar type binding device adopts a pry bar sleeve and a U-shaped plate-shaped take-up support to replace the conventional handle structure, and the pry bar sleeve is fixedly connected to the take-up support, so that the structure is simplified and the manufacturing is more convenient, thereby reducing the manufacturing cost of the product. When the binding device is used, only the pry bar needs to be inserted into the pry bar sleeve, and the pre-tightening of the binding device can be realized by swinging the pry bar back and forth. At this time, since the pry bar can provide a longer lever length, the length of the take-up support can be smaller, so that the structure of the binding device is more compact and the overall size is smaller. In addition, one end of the pry bar sleeve is directed towards the reel and the pry bar sleeve is perpendicular to the reel. Such a design allows the user to better control the force and direction applied, reduces the inclination or swinging of the pry bar sleeve during the force application process, and the force applied by the pry bar to the pry bar sleeve can be more effectively converted into the swinging of the take-up support without being wasted in other directions. This direct torque transmission improves the operation efficiency, so that the user can more easily realize the pre-tightening of the binding device through the pry bar without the need for the handle, thereby making the operation more labor-saving and convenient, and achieving a greater binding pre-tightening force and improving the rated load of the binding device, so that it can be better applied to the binding of heavy goods.

[0012] In the above pry bar type binding device, a baffle is fixedly connected in the take-up support, and one end of the pry bar sleeve directed towards the reel abuts against and is welded to the baffle.

[0013] During use of the binding device, the pry bar sleeve needs to bear a large torque, so it not only needs to be not deformed itself, but also needs to have good connection stability. In view of this, the binding device further fixedly connects a baffle on the take-up support, so that one end of the pry bar sleeve directed towards the reel abuts against and is welded to the baffle. In this way, during repeated swinging of the pry bar, the external force received by the pry bar sleeve is transmitted to the baffle, and the pry bar sleeve is then supported by the baffle, thereby further improving the connection stability of the pry bar sleeve, making the binding device stable and reliable in use, and enabling the binding device to better utilize the pry bar for binding operation to achieve the purpose of labor-saving operation, while the binding device can achieve a higher rated load.

[0014] In the above pry bar type binding device, the pry bar sleeve is integrally formed with the take-up support; or the pry bar sleeve is provided on the take-up support and welded to the take-up support. Specifically, a mounting hole is formed on the take-up support, and the pry bar sleeve is provided in the mounting hole and fixedly connected to the take-up support, so as to ensure that the pry bar sleeve and the take-up support have good connection stability, and the pry bar sleeve is further abutted against the baffle, so that the connection stability of the pry bar sleeve is further improved, thereby improving the use reliability of the binding device and enabling the binding device to better utilize the pry bar for binding operation to achieve the purpose of labor-saving operation.

[0015] In the pry bar type bundler described above, the end faces of the two ends of the baffle plate each have an insertion protrusion, which is inserted and fixed on the take-up support. Further, the insertion protrusion is welded and fixed to the take-up support, or the insertion protrusion and the insertion hole of the take-up support for the insertion of the insertion protrusion form a tight fit. As a preferred, the insertion protrusion is welded and fixed to the take-up support. By increasing the welding points between the insertion protrusion and the take-up support, the connection stability of the baffle plate can be further improved, so that the baffle plate can be more stably supported by the pry bar sleeve, and the connection stability of the pry bar sleeve is further strengthened, and the bundler can better use the pry bar for bundling operation to achieve the purpose of labor saving.

[0016] In the pry bar type bundler described above, the end faces of the two ends of the baffle plate each have an insertion protrusion, which is inserted and fixed on the take-up support. Further, the insertion protrusion is welded and fixed to the take-up support, or the insertion protrusion and the insertion hole of the take-up support for the insertion of the insertion protrusion form a tight fit. As a preferred, the insertion protrusion is welded and fixed to the take-up support. By increasing the welding points between the insertion protrusion and the take-up support, the connection stability of the baffle plate can be further improved, so that the baffle plate can be more stably supported by the pry bar sleeve, and the connection stability of the pry bar sleeve is further strengthened, and the bundler can better use the pry bar for bundling operation to achieve the purpose of labor saving.

[0017] In the pry bar type bundler described above, the two ends of the reel are respectively sleeved with a ratchet wheel that rotates synchronously with the reel, and the take-up support is further provided with a handle that can be embedded in the tooth groove of the ratchet wheel, the handle is in sliding connection with the take-up support, the side of the handle away from the reel has a pulling portion that is bent upward to form a U-shaped structure, and the pulling portion protrudes outward relative to the upper side of the take-up support. When the pry bar drives the take-up support to swing back and forth, the handle swings back and forth together with the take-up support, thereby driving the reel to rotate and achieving the pre-tightening of the bundler. The conventional handle type bundler also has a handle, and in the use process, the handle is usually held by the hand and the handle is hooked by the fingers to pull and move. Different from the conventional handle type bundler, the handle of the present bundler has a pulling portion that is bent upward to form a U-shaped structure, and the pulling portion protrudes outward relative to the upper side of the take-up support. Therefore, on the basis of eliminating the handle, the handle of the present bundler can still be easily pulled and moved, and the product is more convenient to use.

[0018] In the pry bar type bundler described above, the end faces of the two ends of the baffle plate each have an insertion protrusion, which is inserted and fixed on the take-up support. Further, the insertion protrusion is welded and fixed to the take-up support, or the insertion protrusion and the insertion hole of the take-up support for the insertion of the insertion protrusion form a tight fit. As a preferred, the insertion protrusion is welded and fixed to the take-up support. By increasing the welding points between the insertion protrusion and the take-up support, the connection stability of the baffle plate can be further improved, so that the baffle plate can be more stably supported by the pry bar sleeve, and the connection stability of the pry bar sleeve is further strengthened, and the bundler can better use the pry bar for bundling operation to achieve the purpose of labor saving.

The guiding plate can guide and support the handle, and the moving stability of the handle during the bundling operation is improved. Since the sliding part is located in the middle part of the side of the main body away from the winding shaft, and the pulling part is integrally formed on the sliding part, the pulling part is also centrally arranged relative to the main body. Therefore, the pulling part and the two opposite inner side walls of the take-up support are both provided with the spacing, instead of being attached to the two opposite inner side walls of the take-up support. The spacing can facilitate the welding of the end faces of the baffle plates and the take-up support by the welding gun, so that the welding process can be used to ensure that the baffle plates have good connection stability.

The guiding plate can guide and support the handle, and the moving stability of the handle during the bundling operation is improved. Since the sliding part is located in the middle part of the side of the main body away from the winding shaft, and the pulling part is integrally formed on the sliding part, the pulling part is also centrally arranged relative to the main body. Therefore, the pulling part and the two opposite inner side walls of the take-up support are both provided with the spacing, instead of being attached to the two opposite inner side walls of the take-up support. The spacing can facilitate the welding of the end faces of the baffle plates and the take-up support by the welding gun, so that the welding process can be used to ensure that the baffle plates have good connection stability.

[0021] Compared with the prior art, the pry bar type bundler has the following advantages:

[0022] 1. The pry bar type bundler uses a pry bar sleeve and a U-shaped plate-shaped take-up support to replace the traditional handle structure. The pry bar sleeve is fixedly connected to the take-up support, which simplifies the structure and makes the manufacturing more convenient, thereby reducing the manufacturing cost of the product.

[0023] 2. When the bundler is used, the pry bar is inserted into the pry bar sleeve, and the bundler is pre-tightened by moving the pry bar back and forth.
