Description

Technical Field

[0001] This utility model relates to the field of transmission technology, specifically a tension adjustment mechanism for transmission. Background Technology

[0002] Currently, there is a rope-type fully automatic drawer drive structure for use in car refrigerators. The device has a pair of slide rails fixed to the left and right sides of its base plate. A driven turntable is located at the front center of the base plate, and a drawer drive connector is located on the left side. A fixed base is connected to the rear of the base plate, and an active turntable is located on the upper end of the fixed base. The active turntable is connected to a motor at the rear of the fixed base. A rope assembly connects the driven and active turntables. The rope assembly consists of a rope, an internal threaded female seat, and an adjusting bolt. The rope is looped around the active and driven turntables, and both ends of the rope are connected to the two ends of the drawer drive connector. The internal threaded female seat and the adjusting bolt are connected to the middle of the rope, and the tension is adjusted by the depth of the adjusting bolt.

[0003] However, the above-mentioned rope tension adjustment structure has the following shortcomings:

[0004] 1) Existing rope tension adjustment structures mainly use adjusting bolts and threaded nuts for installation. The limitations of the installation position make operation difficult and make it hard to accurately adjust the rope tension, thus affecting the transmission stability.

[0005] 2) The existing rope tension adjustment has poor stability. The assembled flexible rope should be in a moderate tension state, but during the transmission process, the rope is easy to fall off from the driving wheel and driven wheel, which also affects the transmission effect and causes the stability of the drawer drive connector to deteriorate during operation. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tension adjustment mechanism for transmission. It has a simple structure, is easy to assemble, and has a transmission tension adjustment function, so that the transmission tension is moderate, effectively improving the transmission stability and ensuring the stable operation of the product.

[0007] The objective of this invention is achieved as follows: A tension adjustment mechanism for transmission includes a transmission component and a tension adjustment component. The tension adjustment component includes a fixed base, a movable connecting component, a tension wheel, and an adjustment component. The movable connecting component is slidably mounted on the fixed base. The tension wheel is rotatably connected to the movable connecting component. The transmission component is wound around the tension wheel. One end of the adjustment component is positioned and connected to the fixed base, and the other end of the adjustment component is rotatably connected to the movable connecting component. This allows the adjustment component to rotate while simultaneously driving the movable connecting component to move up and down relative to the fixed base, thereby causing the tension wheel to move up and down relative to the fixed base.

[0008] Based on the above optimization, the movable connector is provided with a shaft connection groove, a rolling shaft is installed in the shaft connection groove, and the tensioning wheel is installed on the rolling shaft.

[0009] Based on the above optimization, the fixed base is provided with an adjusting support plate at its end. The adjusting support plate is adapted to be installed on the movable connector, and the left and right ends of the adjusting support plate pass through the movable connector and are adapted to be fixedly installed on the fixed base. One end of the adjusting member abuts against the adjusting support plate, and the other end of the adjusting member is threaded to the movable connector.

[0010] Based on the above optimization, the fixed base has an open mounting groove at its end, the movable connector slides on the open mounting groove, and the two ends of the adjusting support plate are connected to the left and right sides of the open mounting groove.

[0011] Based on the above optimization, guide grooves for linear up-and-down movement of the relative adjustment support plate are respectively opened on both sides of the movable connector.

[0012] Based on the above optimization, the end of the movable connector is provided with an directional groove for directional sliding with the fixed base.

[0013] Based on the above optimization, the tensioning wheel has a transmission groove for easy winding of the transmission component and for driving the tensioning wheel to rotate. The transmission groove is formed on the outer edge of the tensioning wheel by stamping.

[0014] Based on the above optimization, the transmission component can be a rope, a belt, or a steel cable.

[0015] The advantages of this utility model are:

[0016] 1) By employing a structure consisting of a fixed base, a movable connecting part, a tensioning wheel, and an adjusting part, rotating the adjusting part causes the movable connecting part to move up and down relative to the fixed base, thereby driving the tensioning wheel to move up and down, thus adjusting the tension of the transmission component. The structure is simple, easy to operate, provides effective transmission tension, enhances the transmission stability of the transmission component, and ensures the quality of the product.

[0017] 2) Due to the cooperation between the tension wheel, movable connecting parts, and transmission parts in this structure, the transmission parts can be stably connected to the tension wheel, preventing the transmission parts from disengaging during transmission. This also ensures that the transmission parts are at a moderate tension during transmission, improving transmission smoothness, reliability, and practicality, and guaranteeing the product's performance. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention.

[0019] Figure 2 This is an exploded view of a preferred embodiment of the present invention. Detailed Implementation

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] According to the appendix Figures 1 to 2 As shown in the figure, the tension adjustment mechanism for transmission of this utility model includes a transmission component 1 and a tension adjustment component. The tension adjustment component includes a fixed base 2, a movable connecting component 3, a tension wheel 4, and an adjustment component 5. The movable connecting component 3 is slidably mounted on the fixed base 2. The tension wheel 4 is rotatably connected to the movable connecting component 3. The transmission component 1 is wound around the tension wheel 4. One end of the adjustment component 5 is positioned and connected to the fixed base 2, and the other end of the adjustment component 5 is rotatably connected to the movable connecting component 3. This allows the adjustment component 5 to rotate while driving the movable connecting component 3 to move up and down relative to the fixed base 2, thereby causing the tension wheel 4 to move up and down relative to the fixed base 2.

[0022] By employing a structure consisting of a fixed base 2, a movable connecting part 3, a tensioning wheel 4, and an adjusting part 5, rotating the adjusting part 5 allows the movable connecting part 3 to move up and down relative to the fixed base 2, thereby driving the tensioning wheel 4 to move up and down, thus adjusting the tension of the transmission component 1. This design is simple in structure, easy to operate, provides effective transmission tension, enhances the transmission stability of the transmission component 1, and ensures the quality of the product.

[0023] Reference Figures 1 to 2 As shown in the figure, in further detail, the movable connector 3 is provided with a shaft connecting groove 31, a rolling shaft 6 is installed in the shaft connecting groove 31, and the tensioning wheel 4 is installed on the rolling shaft 6.

[0024] Furthermore, the fixed base 2 is provided with an adjusting support plate 7 at its end. The adjusting support plate 7 is adapted to be installed on the movable connector 3, and the left and right ends of the adjusting support plate 7 pass through the movable connector 3 and are adapted to be fixedly installed on the fixed base 2. One end of the adjusting member 5 abuts against the adjusting support plate 7, and the other end of the adjusting member 5 is threaded to the movable connector 3. The adjusting member 5 can be an adjusting bolt.

[0025] That is, after the transmission component 1 moves around the tension wheel 4, since the adjusting component 5 abuts against the adjusting support component, rotating the adjusting component 5 will push the movable connecting component 3 upward or downward, so that the movable connecting component 3 controls the tension wheel 4 to move upward or downward, thereby adjusting the tightness of the transmission component 1.

[0026] Reference Figures 1 to 2As shown in the diagram, further details are provided. The fixed base 2 has an open mounting groove 21 at one end. The movable connector 3 slides onto the open mounting groove 21, and the two ends of the adjusting support plate 7 are connected to the left and right sides of the open mounting groove 21. The use of the open mounting groove 21 facilitates the assembly and disassembly of the movable connector 3 on the fixed base 2, resulting in a simple structure and reduced assembly space.

[0027] The movable connector 3 has guide grooves 32 on both sides for linear up-and-down movement of the relative adjustment support plate 7, and the guide grooves 32 are connected to the shaft connection groove 31.

[0028] Furthermore, the end of the movable connector 3 is provided with a directional groove 33 for directional sliding with the fixed base 2.

[0029] The movable connector 3 of this structure causes the tensioning wheel 4 to move smoothly up and down, thereby realizing the tension adjustment operation of the transmission component 1.

[0030] In addition, the tensioning wheel 4 has a transmission groove 41 for the transmission component 1 to be wound around and to drive the tensioning wheel 4 to rotate. The transmission groove 41 is formed on the outer edge of the tensioning wheel 4 by stamping.

[0031] It enables the transmission component 1 to be stably connected to the tensioning wheel 4, preventing the transmission component 1 from disengaging during transmission, and also ensuring that the transmission component 1 is at a moderate tension during transmission, thereby improving transmission smoothness, reliability, practicality, and guaranteeing the product's performance.

[0032] Furthermore, the transmission component 1 can be a rope, a belt, or a steel cable. Different types of transmission components 1 can be selected according to the actual application to suit the transmission use of different products, ensuring reliability and practicality.

[0033] It is worth noting that the fixed base 2 of this structure can be integrally formed on the drawer connector, such as the middle rail of the slide rail, to achieve synchronous transmission, which makes the structure stable, saves assembly space, enhances synchronous stability, and ensures the product's performance.

[0034] The above specific embodiments are only specific implementations of the present utility model with better effects. All structures that are the same as or equivalent to the tension adjustment mechanism for transmission of the present utility model are within the protection scope of the present utility model.
