Description

Technical Field

[0001] The utility model belongs to the technical field of cargo binding equipment and relates to a binding belt tension detection device. Background Art

[0002] Binding belts are nowadays used to bind and reinforce goods during long-distance and short-distance transportation. In actual use, different types of goods require different degrees of tightness. Therefore, after the goods are tied and fixed with binding belts, it is generally necessary to use a special tension detection device to detect whether the tension of the binding belts meets the standard, and to infer whether the binding strength of the binding belts for the goods meets the required requirements.

[0003] For example, a Chinese patent (application publication number: CN110296782A) discloses a tensioning force gauge, which specifically includes: a seat body, the seat body has a through slot for the binding belt to be inserted, a pressing assembly with a pressure sensing element is provided on one side wall of the through slot, the pressing assembly is connected to the seat body by a thread and can press against the side wall on the other side of the through slot, and the side wall on the other side of the through slot is recessed inwardly corresponding to the pressing assembly.

[0004] In conjunction with paragraphs 0045 to 0048 of the specification and the attached Figure 1-6 It can be seen that the tensioning force gauge is a device in which the base 1 is placed outside the binding belt 9 so that the binding belt 9 is stuck in the through groove 1a. By manually rotating the hand wheel 32, the binding belt 9 is pressed by the pressing rod 3 to bend the binding belt 9 in the length direction, and the real-time tensioning force value is checked through the digital display module 8.

[0005] However, in actual operation, the operator often needs to squat to perform the detection operation, which is very inconvenient. In addition, the binding belt is in a straight and tensioned state when it is tied. When the operator uses the hand belt to rotate the hand wheel to drive the push rod to move downward, the push rod is subjected to the reaction force of the binding belt, which will cause the hand wheel to be delayed, and the resistance force is large, so the operator needs to use tools to realize the rotation of the hand wheel, which is very inconvenient. Summary of the invention

[0006] The purpose of the utility model is to solve the above problems in the existing technology and propose a binding belt tension detection device. The technical problem to be solved by the utility model is: how to improve the convenience of binding belt tension detection.

[0007] The purpose of the utility model can be achieved through the following technical solutions: a binding belt tensioning detection device, including a belt pressing box, a pressure detection sensor with a detection end facing downward is provided at the bottom of the belt pressing box, and the characteristic is that the binding belt tensioning detection device also includes a fixed tube and a movable rod passing through the fixed tube, the belt pressing box is connected to the lower end of the movable rod, the lower end of the fixed tube is provided with two transversely arranged support rods, and a support belt gap is formed between the two support rods, the pressure detection sensor is located directly above the support belt gap, and the upper end of the movable rod is also provided with a connecting rod assembly that can drive the movable rod to move downward so that the detection end of the pressure detection sensor extends into the support belt gap.

[0008] The working principle of the present binding belt tensioning detection device is as follows: before the detection, the lower end of the fixed tube is placed on the binding belt, so that the binding belt abuts against the two support rods and the belt surface of the binding belt is perpendicular to the axis of the movable rod. Then, under the action of the connecting rod assembly, the movable rod passing through the fixed tube is continuously pushed downward until the detection end at the lower end of the movable rod abuts against the belt surface of the binding belt. Under the push of subsequent force, the detection end continuously presses the binding belt, so that the binding belt bends and deforms into the support belt gap until the movement of the movable rod reaches the limit. At this time, the movable rod maintains a positioning state in the fixed tube, and the shape of the binding belt in the support belt gap is squeezed into a V shape. At this time, the reaction force generated by the deformation of the binding belt also acts on the detection end, and the return force received by the detection end in the current state is detected by the pressure detection sensor to realize the detection of the binding belt in the current state. The tensioning force is detected. Compared with the prior art, during the detection process, a connecting rod assembly is hinged with the movable rod, and under the guiding action of the sliding cooperation between the connecting rod assembly and the fixed sleeve, the movable rod is controlled by the lever principle to drive the detection end to press the binding belt, thereby greatly reducing the force that the operator needs to apply on the connecting rod assembly during the test, and there is no need to use tools to complete the operation. At the same time, due to the setting of the fixed tube and the movable rod, the actual operating height of the detection device can be increased to a certain extent. During the detection process, the operator does not need to always maintain a squatting posture, which ensures labor-saving operation and improves the convenience of operation. In addition, the pressure detection sensor disclosed in the present application is a prior art, and a battery and a circuit board connected to the pressure detection sensor through a wire are installed in the belt pressing box. The battery is used to power the sensor, and the circuit board controls its operation.

[0009] In the above-mentioned binding belt tensioning detection device, the connecting rod assembly includes a transmission pin 1 fixed to the upper end of the movable rod radially along the movable rod and a fixed connecting sleeve fixed to the outside of the fixed tube, a hinge plate 1 is hinged on the outer wall of the fixed connecting sleeve, and the upper end of the movable rod is hinged with two hinge plates 2 through the transmission pin 1, and the free ends of the hinge plate 1 and the hinge plate 2 are hinged through the transmission pin 2. When the transmission pin 2 drives the movable rod to move downward relative to the fixed tube through the hinge plate 1 and the hinge plate 2 and makes the transmission pin 2 located below the fixed connecting sleeve, the detection end of the detection sensor extends into the support belt gap. During operation, when the user presses the transmission pin 2 downward until the transmission pin 2 moves to a position below the fixed connecting sleeve, the transmission pin 1 hinged to the transmission pin 2 through the hinge plate 2 will also be subjected to a downward force, that is, the upper end of the movable rod is pressed downward, so that the movable rod drives the detection end to press downward on the belt surface of the binding belt. Conversely, when the transmission pin 2 moves to above the fixed connecting sleeve, the movable rod can move upward to separate the pressure detection sensor from the binding belt, and because the transmission pin 2 is hinged to the fixed connecting sleeve through the hinge plate 1, the sliding direction of the movable rod is guided by the fixed connecting sleeve.

[0010] In the above-mentioned binding belt tensioning detection device, the connecting rod assembly also includes a handle in the shape of a long strip and hinged on the outer wall of the fixed connecting sleeve, and a strip hole is opened on the handle along the length direction. The second transmission pin is slidably connected in the strip hole. When the free end of the handle is facing downward and the outer wall and the outer wall of the fixed tube are abutted, the second transmission pin is located at the lower end of the strip hole. On the basis of the above scheme, the handle is set to make the force arm longer, ensuring that the operation process is more labor-saving, and the transmission pin 2 is accommodated through the strip hole, thereby avoiding interference between the transmission pin 2 and the handle during the entire operation process. In addition, it is worth mentioning that the positioning of the movable rod and the belt press box in the present application is achieved by the outer wall of the handle and the outer wall of the fixed tube in abutting manner. Specifically, when the operator continues to press the handle to make the movable rod drive the belt press box to move downward, the handle swings downward around the hinge between itself and the fixed connecting sleeve until the outer wall of the handle and the outer wall of the fixed tube abut against each other. At this time, due to the limitation of the outer wall of the fixed tube on the swing amplitude of the handle, the belt press box can naturally remain positioned at the maximum formed position after moving downward for a certain distance, thereby ensuring the accuracy of the detection result.

[0011] In the above-mentioned binding belt tensioning detection device, a bracket is provided at the lower end of the fixed tube, and the bracket includes a plate-shaped horizontal section and a vertical section, the horizontal section is connected to the lower end of the fixed tube, and the two support rods are fixed on the horizontal section in the transverse direction. The bracket installed at the lower end of the fixed tube can effectively ensure that the two support rods are positioned in a transverse arrangement with the side walls facing each other, and the bearing gap formed between the two support rods is large enough to accommodate the detection end. When performing the detection work, the operator only needs to put the bracket outside the binding belt, and the side walls of the two support rods and the surface of the binding belt are pressed against each other. When the binding belt is pressed by the detection end, the two support rods can also provide a good force point for the binding belt, ensuring that the binding belt can be fully stressed and apply a reaction force to the detection end of the pressure detection sensor accordingly, thereby ensuring the accuracy of the detection result of the pressure detection sensor.

[0012] In the above-mentioned binding belt tension detection device, a clearance hole for the movable rod to pass through is provided on the horizontal section, a connecting sleeve is provided between the fixed tube and the bracket, a step portion is formed between the two ends of the connecting sleeve along the circumferential direction, the lower end of the fixed tube is clamped with the upper end of the connecting sleeve and abuts against the inner wall of the step portion, and the lower end of the connecting sleeve is clamped in the clearance hole and abuts against the outer wall of the step portion against the surface of the horizontal section. Through this arrangement, it can be ensured that the bracket and the fixed tube are stably connected, and the two can be disassembled, ensuring lower maintenance and repair costs.

[0013] In the above-mentioned binding belt tension detection device, an annular groove is formed at the lower end of the movable rod along the circumferential direction, and a buffer spring is provided in the fixed tube, one end of the buffer spring is pressed against the inner wall of the step portion, and the other end is pressed against the groove wall on one side of the annular groove. With this arrangement, when the movable rod drives the belt pressing box to move downward, the buffer spring fully buffers the movable rod, ensuring that the detection end of the pressure detection sensor applies force on the binding belt more smoothly and softly.

[0014] Compared with the prior art, the present binding belt tension detection device has the following advantages:

[0015] Through the linkage mechanism cooperating with the movable rod and the fixed tube, the movable rod is driven by the lever principle along the length direction of the fixed tube to drive the belt pressing box to move downward a certain distance and position it, so that the detected end of the binding belt is squeezed into the gap between the support belts and deformed, and the reaction force generated by the deformation of the binding belt is used to act on the detection end of the pressure detection sensor, and the detection end of the pressure detection sensor feeds back to the pressure detection sensor so that the operator can detect the tension of the binding belt in the current state. During the operation, there is no need to contact tools to achieve the top pressure of the binding belt, and due to the existence of the movable rod and the fixed tube, the operator does not need to squat all the time to operate, ensuring that the detection is more convenient.

The binding belt tension detection device also includes a long active rod 3, a tubular fixed tube 2 and a connecting rod assembly 4. The active rod 3 is inserted into the fixed tube 2, and the belt pressing box 8 is screwed to the lower end of the active rod 3, combined with Figure 5 A bracket 22 is provided at the lower end of the fixed pipe 2. The bracket 22 specifically includes a horizontal section 221 arranged in the transverse direction and a vertical section 222 arranged in the vertical direction. A clearance hole 2211 is opened on the horizontal section 221. Figure 6A connecting sleeve 7 is provided between the lower end of the fixed tube 2 and the bracket 22. The connecting sleeve 7 is located on the side wall between the two ends and forms a step portion 7171 along the circumferential direction. The lower end of the fixed tube 2 and the connecting sleeve 7 are clamped (or welded) and abut against the inner wall of the step portion 7171. The lower end of the connecting sleeve 7 is clamped (or welded) with the clearance hole 2211 and the outer wall of the step portion 7171 and the surface of the horizontal section 221 are abutted. The lower end of the movable rod 3 is provided with an annular groove 31 along the circumferential direction. A buffer spring 23 is provided in the fixed tube 2. One end of the buffer spring 23 and the groove wall of the annular groove 31 facing the step portion 71, and the other end is tightly abutted against the outer wall of the step portion 71.

[0025] like Figure 3 and Figure 4 As shown, the movable rod 3 is inserted into the clearance hole 2211 so that the belt pressing box 8 is located below the horizontal section 221, and two horizontally arranged support rods 2221 are fixed on the side plate of the vertical section 222 facing the movable rod 3 by screwing, welding or clamping. The side walls of the two support rods 2221 are arranged opposite to each other, and a support gap 21 is formed between the two support rods 2221, and the detection end 11 is located directly above the support gap 21.

[0026] like Figure 3 As shown, the connecting rod assembly 4 is specifically arranged at the upper end of the movable rod 3. Specifically, the connecting rod assembly 4 includes a transmission pin 41 fixed to the upper end of the movable rod 3 along the radial direction of the movable rod 3, a fixed connecting sleeve 42 fixedly arranged outside the fixed tube 2, and a handle 43 in the shape of a long strip and hinged to the fixed connecting sleeve 42 at one end. It is worth mentioning that the fixed connecting sleeve 42 and the fixed tube 2 can be assembled by welding or clamping. In addition, the connecting rod assembly 4 also includes a transversely arranged transmission pin 2 44, and two hinged plates 1 5 are provided between the transmission pin 2 44 and the fixed connecting sleeve 42. One end of each hinged plate 5 is hinged to the transmission pin 2 44, and the other end is hinged to the fixed connecting sleeve 42. The connecting rod assembly 4 also includes two hinged plates 2 6. One end of each hinged plate 5 is hinged to the transmission pin 1 41, and the other end is hinged to the transmission pin 2 44. A strip hole 431 is provided on the handle 43 . The strip hole 431 is provided along the length direction of the handle 43 and passes through the two side surfaces of the handle 43 . The second transmission pin 44 is slidably connected in the strip hole 431 .

[0027] Operation principle: Before the operator performs the detection work, the bracket 22 is set outside the binding belt that needs to be tensioned, so that the binding belt abuts against the two support rods 2221. At this time, the operator can press the handle 43 with force continuously, so that the connecting rod assembly 4 drives the movable rod 3 to move downward along the length direction of the fixed tube 2. In this process, the pressing box 8 fixed at the lower end of the movable rod 3 will move downward together, and the detection end 11 at the bottom of the pressure detection sensor 1 will continuously press the belt surface of the binding belt, so that the binding belt is continuously squeezed into the support gap 21 and deformed, until the side wall of the handle 43 abuts against the outer wall of the fixed tube 2. In this case, the reaction force generated by the deformation of the binding belt is also applied to the detection end 11 of the pressure detection sensor 1, and the pressure is fed back to the pressure detection sensor 1 through the detection end 11 of the pressure detection sensor 1. The tension of the binding belt in the current state is calculated by the data detected by the pressure detection sensor 1. After completing the detection, the operator only needs to pull the handle 43 upward to loosen the binding belt. In addition, it is worth mentioning that this binding belt tensioning detection device is used for some binding belts used to tighten the tires of two-wheeled vehicles. When the binding belt is in a relatively low position, the scheme described in this embodiment can be adopted. For the situation where the binding belt is in an upper position, a binding belt tensioning detection device with a shorter fixed tube 2 and movable rod 3 can be manufactured according to actual conditions for use.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
