Description

Technical Field

[0001] This specification relates to the field of medical device technology, and in particular to a tube column trolley structure. Background Technology

[0002] Fixed X-ray imaging equipment typically requires precise horizontal and vertical movement of the X-ray tube to achieve the ideal imaging position. Currently, most structures supporting the horizontal movement of the X-ray tube are manual, with electric mechanisms being relatively rare. While manual adjustment is straightforward, it has limitations in terms of ease of operation and precision, especially when frequent adjustments or fine positioning are required, resulting in lower efficiency.

[0003] While electric motors significantly improve operational convenience and positioning accuracy, their implementation requires additional motors and electronic control systems. Furthermore, the placement of the motor is crucial, necessitating consideration of the overall compactness and stability of the equipment. Existing electric solutions still have room for improvement in terms of drive control complexity and trolley structure design.

[0004] Therefore, there is a need to provide an improved trolley structure for the PV tube column. Utility Model Content

Detailed Implementation

[0017] To more clearly illustrate the technical solutions of the embodiments in this specification, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this specification. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0018] Most of the trolleys used to control the movement of the X-ray tube in fixed X-ray imaging equipment are manual structures, consisting of a trolley body and rollers. The tube mounting position provides a handle for operation. After each imaging session, staff need to enter the examination room to adjust the tube before the next imaging session, which is a cumbersome process.

[0019] In some embodiments, the trolley is driven by a motor assembly located at one end of the ground rail. The related cables are complex and, if not properly secured or become detached after long-term use, can easily be caught in the trolley, causing obstruction of movement. Furthermore, some of the motion cables that cannot be secured may experience wear and tear. In addition, the motor assembly is located on the outside of the X-ray imaging equipment. When performing free-panel imaging on patients in wheelchairs or with limited mobility, improper operation can easily cause collisions with the motor assembly, resulting in damage to the motor assembly.

[0020] In view of this, some embodiments of this specification provide an improved trolley structure for the X-ray tube column. This structure is compact, easy to drive and control, and supports two transmission methods for electric motion, allowing the operator to flexibly and precisely control the horizontal movement of the X-ray tube column via remote control or other means. Furthermore, while ensuring electric drive functionality, it is also compatible with a manual operation mode, providing users with greater flexibility and convenience, thereby effectively improving the operating experience and work efficiency.

[0021] Figure 1 This is a structural schematic diagram of the cyclone tube column trolley structure shown in some embodiments of this specification. Figure 2 yes Figure 1 A schematic diagram of the structure at point A.

[0022] In some embodiments, such as Figure 1 As shown, the X-ray tube column trolley structure 10 includes an X-ray tube column assembly 100, a trolley assembly 200, and a guide rail assembly 300.

[0023] The X-ray tube stand assembly 100 is used to support and move the X-ray tube, enabling adjustment of the tube in different directions and positions to meet the needs of X-ray imaging of different parts of the patient. In some embodiments, the X-ray tube stand assembly 100 includes a camera 130, such as an X-ray camera. In some embodiments, the X-ray tube stand assembly 100 includes a stand body 110. The stand body 110 is positioned vertically (e.g., along the vertical direction). Figure 1 The camera 130 (in the Z direction shown) is mounted on the trolley assembly 200. In some embodiments, the camera 130 can move vertically on the column body 110 to facilitate adjustment of the height of the camera 130. For example, the X-ray tube column assembly 100 may be provided with a track extending vertically, in which the camera 130 can be slidably mounted.

[0024] In some embodiments, the X-ray tube column assembly 100 can be made of a variety of materials, such as at least one of aluminum alloy and titanium alloy. This reduces its weight while maintaining strength, thus facilitating movement and operation.

[0025] In some embodiments, the X-ray tube column assembly 100 is connected to the trolley assembly 200. In some embodiments, the X-ray tube column assembly 100 is rotatably mounted on the trolley assembly 200, and the rotation axis of the X-ray tube column assembly 100 is parallel to the vertical direction, thereby adjusting the angle of the X-ray tube column assembly 100 relative to the trolley assembly 200, thereby adjusting the shooting angle of the camera 130.

[0026] The trolley assembly 200 is used to mount the X-ray tube column assembly 100. When the trolley assembly 200 moves, it can drive the X-ray tube column assembly 100 to move synchronously.

[0027] In some embodiments, such as Figure 2 As shown, the trolley assembly 200 includes a trolley body 220, which is connected to the X-ray tube column assembly 100. The trolley body 220 is provided with a drive assembly 210, and the trolley body 220 is movably mounted on the guide rail assembly 300 via the drive assembly 210.

[0028] In some embodiments, the upper portion of the tube column assembly 100 may be rotatably connected to the trolley body 220. The lower portion of the trolley body 220 may be adapted to at least a portion of the guide rail assembly 300 to allow the trolley body 220 to move relative to the guide rail assembly 300.

[0029] The drive assembly 210 is used to output power to drive the trolley body 220. See the description below for more information about the drive assembly.

[0030] The guide rail assembly 300 is used to mount the trolley assembly 200 and is capable of guiding the movement direction of the trolley assembly 200. For example, the guide rail assembly 300 can guide the trolley assembly 200 along the length direction of the guide rail assembly 300 (e.g., ...). Figure 1 Move in the X direction (as shown).

[0031] In some embodiments, the guide rail assembly 300 can be fixedly mounted on a horizontal surface, such as the ground, desktop, workbench, etc.

[0032] The trolley structure for the tube column provided in some embodiments of this specification is powered by a drive component set in the trolley assembly. It has a compact and simple structure and can easily and accurately realize the automated control of the trolley assembly, allowing the trolley body to move flexibly on the guide rail assembly.

[0033] Figure 3 This is a structural schematic diagram of a trolley assembly according to some embodiments of this specification.

[0034] In some embodiments, such as Figure 2 , Figure 3 As shown, the guide rail assembly 300 includes a slide rail 310, and the trolley body 220 includes a rolling wheel 211. The trolley body 220 makes rolling contact with the slide rail 310 through the rolling wheel 211.

[0035] The slide rail 310 has a groove or ridge extending along its length to engage with and guide the trolley body 220 along it.

[0036] In some embodiments, the slide rail 310 can be made of a variety of materials, such as stainless steel, aluminum alloy, titanium alloy, etc., and processed to form a smooth surface structure to reduce friction and ensure its structural strength.

[0037] For example, slide rail 310 is along the width direction (e.g.) Figure 2Guide grooves 311 are provided on both sides of the slide rail 310 (shown in the Y direction). The guide grooves 311 extend along the length of the slide rail 310. The trolley body 220 is provided with guide protrusions, which are engaged in the guide grooves 311.

[0038] By setting the slide rail to match the trolley body, the connection strength and stability between the trolley body and the slide rail can be improved.

[0039] Roller 211 is rotatably mounted on trolley body 220. In some embodiments, roller 211 is roll-connected to at least one surface of slide rail 310.

[0040] By setting rolling wheels, the trolley body can roll into contact with the slide rail as it moves along the slide rail. This results in less friction compared to sliding friction, which reduces wear between the trolley body and the slide rail, and reduces resistance when the trolley body moves.

[0041] In some embodiments, the rollers 211 can serve as load-bearing wheels, supporting the weight of the tube column assembly 100 and the trolley assembly 200. In some embodiments, there can be multiple rollers 211, which can be symmetrically distributed along the length of the slide rail 310. In some embodiments, the rollers 211 can be made of polyetheretherketone (PEEK), nylon (such as PA12C), or other similar materials with high compressive strength and wear resistance.

[0042] In some embodiments, the rotational speed of the rolling wheel 211 is 300~500 r / min. In some embodiments, the rotational speed of the rolling wheel 211 is 350~450 r / min. In some embodiments, the rotational speed of the rolling wheel 211 is approximately 400 r / min. In some embodiments, the coefficient of friction between the rolling wheel 211 and the slide rail 310 is 0.1~0.3. In some embodiments, the coefficient of friction between the rolling wheel 211 and the slide rail 310 can be 0.2~0.3. In some embodiments, the coefficient of friction between the rolling wheel 211 and the slide rail 310 is approximately 0.25.

[0043] It should be noted that the trolley assembly 200 can be powered by the drive assembly 210 to move along the guide rail assembly 300. When operation is required, the drive assembly 210 can also be activated without manually pushing the trolley assembly 200 to move along the guide rail assembly 300.

[0044] Figure 4 This is a partial exploded view of the trolley assembly shown in some embodiments of this specification. Figure 5 This is a schematic diagram showing the connection between the driven wheel and the rolling wheel according to some embodiments of this specification. Figure 6 This is a schematic diagram showing the connection between the driven wheel and the rolling wheel according to some embodiments of this specification.

[0045] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the drive assembly 210 includes a transmission belt 214, a first motor 212, a drive wheel 213, and at least one driven wheel 215. The first motor 212 is connected to the drive wheel 213 for transmission. The transmission belt 214 is sleeved on the drive wheel 213 and at least one driven wheel 215. At least one driven wheel 215 and a rolling wheel 211 are coaxially fixedly connected through a first transmission shaft 217.

[0046] The first motor 212 is used to output torque. The first motor 212 can be selected as needed. In some embodiments, the torque output by the first motor 212 needs to meet a preset starting force requirement. For example, if the preset starting force requirement is 50N, the rated speed of the first motor 212 can be approximately 3000 r / min, and the rated torque can be greater than 0.286 Nm.

[0047] In some embodiments, the drive wheel 213 is connected to the output shaft of the first motor 212, and the first motor 212 can drive the drive wheel 213 to rotate. In some embodiments, the first motor 212 also includes a reducer and an encoder. The reducer can reduce the speed, increase the torque, and improve the control accuracy. The encoder can monitor the rotation of the electrodes in real time and provide feedback on position and speed information, thereby enabling control and calibration of the motor rotation and achieving automated control of the movement of the trolley body 220.

[0048] The driving wheel 213 drives at least one driven wheel 215 to rotate via the transmission belt 214. In some embodiments, the rotation axes of the driving wheel 213 and the driven wheel 215 can be parallel, and the rotation axis of the driving wheel 213 can be parallel to the width direction of the slide rail 310 (e.g., Figure 2 (in the Y direction). In some embodiments, the diameters of the driving wheel 213 and the driven wheel 215 may be the same or different, and can be set according to actual needs.

[0049] In some embodiments, the number of driven wheels 215 can be multiple. For example, there are two driven wheels 215, respectively disposed on both sides of the trolley body 220. As another example, there are four driven wheels 215, evenly distributed on both sides of the trolley body 220.

[0050] In some embodiments, the driving wheel 213 and the driven wheel 215 may be made of the same material as the rolling wheel 211, or they may be made of other materials, such as plastic, rubber, etc.

[0051] In some embodiments, limiting grooves may be provided on the driving wheel 213 and the driven wheel 215, and the transmission belt 214 is locked in the limiting grooves to prevent the transmission belt 214 from detaching from the driving wheel 213 or the driven wheel 215, thereby ensuring the safety and stability of the transmission belt 214 when it rotates.

[0052] By using a transmission belt to transmit the power of the first motor to the rolling wheels via the driving wheel and at least one driven wheel, the smooth movement of the trolley along the slide rail is achieved. The combination of the transmission belt, driving wheel, and driven wheel ensures the stability and efficiency of power transmission. In addition, the coaxial fixed connection ensures that power can be directly and accurately transmitted to the rolling wheels.

[0053] In some embodiments, the drive assembly 210 further includes a tension pulley 216, around which the drive belt 214 is wound.

[0054] The tensioner pulley can tension the drive belt, ensuring a larger wrap angle on the drive belt to guarantee normal transmission and reduce the risk of slippage.

[0055] In some embodiments, the first drive shaft 217 passes through the side wall of the trolley body 220, and the driven wheel 215 and the rolling wheel 211 may be respectively disposed on both sides of the side wall of the trolley body 220. In some embodiments, at least a portion of the first drive shaft 217 is rotatably connected to the trolley body 220.

[0056] In some embodiments, such as Figure 5 and Figure 6 As shown, the first drive shaft 217 passes through the first bearing 218 located near the rolling wheel 211 and the second bearing 219 located near the driven wheel 215 in sequence. The first drive shaft 217 is connected to the trolley body 220 through the first bearing 218 and the second bearing 219. The size of the first bearing 218 is smaller than that of the second bearing 219.

[0057] In some embodiments, the trolley body 220 is provided with a first bearing groove adapted to the outer ring of the second bearing 219. The outer ring of the second bearing 219 is mounted in the first bearing groove, and the first bearing groove restricts the axial movement of the outer ring of the second bearing 219 along the first drive shaft 217. In some embodiments, a baffle 2191 is provided on the side of the second bearing 219 near the driven wheel 215. The baffle 2191 may be provided on the outside of the trolley body 220, forming the first bearing groove with the trolley body 220. In some embodiments, the baffle 2191 and the trolley body 220 may be connected in a variety of ways, such as at least one of snap-fit, threaded connection, etc.

[0058] In some embodiments, the first drive shaft 217 is provided with a second bearing groove adapted to the inner ring of the second bearing 219, the inner ring of the second bearing 219 is mounted in the second bearing groove, and the second bearing groove restricts the axial movement of the inner ring of the second bearing 219 along the first drive shaft 217. In some embodiments, a collar 2192 is provided on the side of the second bearing 219 near the driven wheel 215, and a spacer 2171 is provided on the side of the second bearing 219 away from the driven wheel 215, the collar 2192 and the spacer 2171 forming the second bearing groove. In some embodiments, the collar 2192 and the spacer 2171 can be connected to the first drive shaft 217 in a variety of ways, such as at least one of snap-fit, threaded connection, etc.

[0059] This configuration ensures that the position between the first drive shaft and the second bearing remains relatively stable, thereby reducing the axial movement of the second bearing along the first rotating shaft and improving transmission stability.

[0060] In some embodiments, the first drive shaft 217 is provided with a third bearing groove adapted to the inner ring of the first bearing 218. The inner ring of the first bearing 218 is mounted in the third bearing groove, and the third bearing groove restricts the axial movement of the inner ring of the first bearing 218 along the first drive shaft 217. In some embodiments, a shoulder 2172 is provided on the first drive shaft 217. The shoulder 2172 is located on the side of the first bearing 218 near the rolling wheel 211, and the shoulder 2172 and the spacer 2171 form the third bearing groove. In some embodiments, the outer diameter of the shoulder 2172 is larger than the inner diameter of the inner ring of the first bearing 218, but smaller than the outer diameter of the inner ring of the first bearing 218.

[0061] In some embodiments, the outer ring of the first bearing 218 can be a free end, that is, the outer ring of the first bearing 218 is not restricted in the bearing groove, so that there is a certain amount of movement space along the axial direction of the first transmission shaft 217, ensuring that the bearing assembly will not be completely locked so that it cannot rotate.

[0062] In some embodiments, the spacer 2171 is sleeved on the first drive shaft 217 and located between the first bearing 218 and the second bearing 219 to form a bearing groove and keep the position between the first drive shaft 217 and the second bearing 219 relatively stable.

[0063] In some embodiments, the dimensions of the first bearing 218 and the second bearing 219 may be the same or different. For example, the dimension of the first bearing 218 may be smaller than that of the second bearing 219. The use of two bearings of different dimensions is primarily based on considerations of bearing fixation and machining. Using bearings of the same size might prevent the outer rings on opposite sides of the two bearings from being effectively fixed, resulting in incomplete elimination of clearance and causing movement. Furthermore, the mating surfaces of the bearings in contact with the trolley body 220 require precision machining, while the two bearings, having no mating relationship, do not require such machining.

[0064] Figure 7 This is a schematic diagram of the structure of the drive component according to other embodiments of this specification. Figure 8 This is an exploded view of the drive assembly shown according to other embodiments of this specification.

[0065] In some embodiments, such as Figure 7 and Figure 8 As shown, the cyclone tube column trolley structure 10 also includes a synchronous belt 231, and the drive assembly 210 includes a second motor 232 and a transmission assembly. The transmission assembly is fixedly connected to the trolley body 220, the second motor 232 is driven by the transmission assembly, the transmission assembly is driven by the synchronous belt 231, and the synchronous belt 231 extends in the same direction as the guide rail assembly 300.

[0066] The second motor 232 has the same structure and function as the first motor 212, and will not be described again.

[0067] The timing belt 231, in conjunction with the transmission assembly, guides the movement of the trolley body 220, causing the trolley body 220 to move along the length of the slide rail 310 (e.g., ...). Figure 8 Move in the X direction (as shown).

[0068] In some embodiments, the synchronization belt 231 is a long strip-shaped structure, and the width direction of the synchronization belt 231 is along the vertical direction (e.g., Figure 8 (Z direction shown). In some embodiments, the timing belt 231 may be made of a soft material, such as at least one of rubber, silicone, plastic, etc. In some embodiments, the timing belt 231 and the transmission assembly may be driven by a variety of methods, such as at least one of friction, meshing, etc.

[0069] In some embodiments, the timing belt 231 may be disposed on both sides of the trolley body 220, and transmission components are disposed on both sides of the trolley body 220 respectively.

[0070] The transmission assembly can be used to transmit the torque output by the second motor 232. Under the action of the torque, the transmission assembly moves relative to the synchronous belt 231, thereby causing the transmission assembly to move along the length of the synchronous belt 231, which can drive the trolley body 220 to move.

[0071] The synchronous belt, the second motor, and the transmission assembly enable the trolley body to move efficiently along the guide rail assembly. The synchronous belt is set on both sides of the guide rail assembly and arranged along its extension direction, and can play a role in buffering, vibration reduction, and noise reduction, making the transmission smoother. The second motor directly transmits power to the synchronous belt through the transmission assembly, providing a strong and stable power output.

[0072] Figure 9This is a schematic diagram of the transmission assembly according to other embodiments of this specification.

[0073] In some embodiments, such as Figure 9 As shown, the transmission assembly includes a fixed base 233, a main pulley 234, and at least one auxiliary idler pulley 235. A timing belt 231 is wound between the main pulley 234 and at least one auxiliary idler pulley 235.

[0074] The mounting base 233 is used to mount the main wheel 234 and at least one auxiliary idler wheel 235. In some embodiments, the mounting base 233 is fixedly connected to the trolley body 220, and the main wheel 234 and at least one auxiliary idler wheel 235 are fixedly mounted on the mounting base 233. The fixed connection can be a snap-fit ​​connection, a threaded connection, etc.

[0075] The main wheel 234 is used to drive the second motor 232. The torque output by the second motor 232 drives the main wheel 234 to rotate, causing the main wheel 234 to move relative to the synchronous belt 231, thereby causing the main wheel 234 to move along the length of the synchronous belt 231, and then driving the trolley body 220 to move synchronously through the fixed seat 233.

[0076] In some embodiments, the main pulley 234 and the timing belt 231 can be driven by rolling friction. In some embodiments, the rotation axis of the main pulley 234 can be parallel to the vertical direction (e.g., Figure 8 (The Z direction is shown).

[0077] The auxiliary idler pulley 235 is rolledly connected to the timing belt 231 to increase the contact area between the timing belt 231 and the transmission components, thereby improving the stability and reliability of the transmission. When the main pulley 234 moves along the length of the timing belt 231, the auxiliary idler pulley 235 can be passively rotated due to the rolling friction between it and the timing belt 231. In some embodiments, the rotation axis of the auxiliary idler pulley 235 can be parallel to the rotation axis of the main pulley 234.

[0078] For example, such as Figure 9 As shown, two auxiliary idler wheels 235 can be provided, and the two auxiliary idler wheels 235 can be respectively provided on both sides of the main wheel 234, that is, along a plane perpendicular to the rotation axis of the main wheel 234 (e.g. Figure 9 As shown in the paper, the rotation axes of the two auxiliary idler wheels 235 and the rotation axis of the main wheel 234 can be distributed in an acute triangle. The synchronous belt 231 passes around one auxiliary idler wheel 235-1, the main wheel 234 and another auxiliary idler wheel 235-2 in sequence.

[0079] By setting an auxiliary idler pulley, the contact area between the timing belt and the main pulley can be increased, thereby improving the stability of the transmission. It can also optimize the stress conditions inside the transmission components and tighten the timing belt, making the transmission smoother and reducing the wear of the auxiliary idler pulley and the main pulley.

[0080] The transmission is achieved by using the main wheel, auxiliary idler wheel and synchronous belt, which helps to move the trolley body smoothly and efficiently; the synchronous belt is wound between the main wheel and the auxiliary idler wheel, which helps to optimize the force distribution and reduce the wear of individual components; the auxiliary idler wheel can be used to tension the synchronous belt to ensure the stability and accuracy of operation.

[0081] Figure 10 This is a partial structural schematic diagram of a transmission assembly according to other embodiments of this specification. Figure 11 This is a schematic diagram of synchronous belt engagement according to other embodiments of this specification.

[0082] In some embodiments, such as Figure 8 and Figure 10 As shown, the transmission assembly also includes a second transmission shaft 236, a first bevel gear 237, and a second bevel gear 238. The second transmission shaft 236 is mounted on the fixed base 233 via a third bearing 239, the first bevel gear 237 is located at the output end of the second motor 232, and the second bevel gear 238 is coaxially and fixedly connected to the main wheel 234 via the second transmission shaft 236.

[0083] The first bevel gear 237 is used to transmit the torque output by the second motor 232. The first bevel gear 237 meshes with the second bevel gear 238, which enables the first bevel gear 237 to drive the second bevel gear 238 to rotate, thereby changing the power direction of the second motor 232. This allows the rotational driving force provided by the second motor 232, which is mounted on the XY plane, to be changed from rotation around a straight line located on the XY plane to rotation around the Z-axis.

[0084] The second drive shaft 236 transmits the torque of the second bevel gear 238 to the main gear 234, thereby driving the main gear 234 to rotate. The second drive shaft 236 is mounted on the fixed base 233 via a third bearing 239, allowing the second drive shaft 236 to rotate relative to the fixed base 233. This also reduces wear on the second drive shaft 236, maintains its shape accuracy, and prevents wear and deformation from affecting the transmission effect. In some embodiments, two third bearings 239 may be provided, respectively located at both ends of the second drive shaft 236, thereby improving the stability of the second drive shaft 236.

[0085] By utilizing the meshing of the first bevel gear and the second bevel gear, the direction of the driving force provided by the second motor can be changed, thereby facilitating the installation of the second motor, making the installation position of the second motor more flexible, saving installation space, facilitating the arrangement of components, and making the structure compact.

[0086] In some embodiments, the timing belt 231 has a first tooth, the main pulley 234 has a second tooth, and at least one auxiliary idler pulley 235 has a third tooth. The first tooth meshes with the second tooth and the third tooth, respectively. See also the example of the meshing of the timing belt 231 with the main pulley 234 or the auxiliary idler pulley 235. Figure 11 As shown.

[0087] The first, second, and third teeth are tooth-like structures. By engaging the first tooth with the second and third teeth respectively, the fit strength between the synchronous belt and the main pulley, and between the synchronous belt and the auxiliary idler pulley, can be improved, preventing slippage and ensuring high precision and synchronization of power transmission.

[0088] Figure 12 This is a structural schematic diagram of a tensioning assembly according to other embodiments of this specification.

[0089] In some embodiments, such as Figure 12 As shown, the transmission assembly also includes a tensioning assembly 240, which includes a first clamping plate 241 and a second clamping plate 242, with the timing belt 231 clamped between the first clamping plate 241 and the second clamping plate 242.

[0090] The tensioning assembly 240 can be used to tension the synchronous belt 231 to prevent the synchronous belt 231 from becoming loose and affecting the transmission efficiency.

[0091] The first clamping plate 241 and the second clamping plate 242 are plate-shaped structures. In some embodiments, the first clamping plate 241 and the second clamping plate 242 can be connected to the guide rail assembly 300 in various ways, such as snap-fit, threaded connection, etc.

[0092] Figure 13 This is an exploded view of the fixed end according to other embodiments of this specification. Figure 14 This is an exploded view of the adjustment end according to other embodiments of this specification.

[0093] In some embodiments, the tensioning assembly 240 may include a fixed end and an adjusting end. The fixed end is used to fix the timing belt 231, and the adjusting end is used to adjust the tension of the timing belt 231. The fixed end and the adjusting end may be respectively located at both ends of the slide rail 310.

[0094] In some embodiments, such as Figure 13 As shown, the fixed end includes a first mounting base 243, a fixed pressure plate 244, and a first toothed plate 245. The timing belt 231 is disposed between the fixed pressure plate 244 and the first toothed plate 245. The first toothed plate 245 meshes with the first tooth of the timing belt 231. The fixed pressure plate 244 is fixedly connected to the first mounting base 243 (e.g., by a threaded connection), thereby clamping and fixing the first toothed plate 245 and the timing belt 231.

[0095] In some embodiments, such as Figure 14 As shown, the adjusting end includes a second mounting base 246, an adjusting pressure plate 247, a second toothed plate 248, and an adjusting screw 249. A synchronous belt 231 is positioned between the adjusting pressure plate 247 and the second toothed plate 248. The second toothed plate 248 engages with the first tooth of the synchronous belt 231. The adjusting pressure plate 247 is threadedly connected to the second mounting base 246, thereby clamping and fixing the second toothed plate 248 and the synchronous belt 231. The second mounting base 246 has an elongated hole 2461, and the adjusting pressure plate 247 has a screw hole. A screw 2462 passes through the elongated hole 2461 and the screw hole respectively to fix the second mounting base 246 and the adjusting pressure plate 247. The adjusting screw 249 passes through at least one bearing protrusion 2471 of the adjusting pressure plate 247, and the end of the adjusting screw 249 away from its head can abut against the slide rail 310.

[0096] For example, when adjusting the tension of the timing belt 231, rotating the adjusting screw 249 causes the adjusting plate 247 to move along the extension direction of the adjusting screw 249, thereby driving the timing belt 231 to move synchronously and adjusting its tension. When the adjusting plate 247 moves, the screw 2462 moves along the elongated hole 2461, the length of which is the travel range of the adjusting plate 247, i.e., the tension adjustment range. It is understandable that when adjusting the tension of the timing belt 231, a tension measuring device (such as an acoustic tension meter) can be used to measure the tension to ensure that the timing belt 231 meets the required tension.

[0097] By incorporating a tensioning assembly, the tension of the timing belt can be adjusted as needed to meet practical application requirements, thereby improving transmission efficiency and positioning accuracy. When the timing belt becomes loose due to deformation, adjusting its tension can extend its service life and reduce operating costs.
