Description

Technical Field

[0001] The invention belongs to the field of fitness equipment, and in particular relates to a frame and a monitoring component of a rowing machine. Background Art

[0002] Existing rowing machines generally achieve the effect of exercise in the process of reciprocating the pull belt through the cooperation of the brake mechanism and the transmission mechanism. The rowing machine monitors the speed through the Hall sensor. The speed display and the adjustment of the resistance of the brake mechanism can be adjusted by the controller and displayed on the display screen of the controller. However, during the use of the rowing machine, only effective reciprocation with a certain speed and sufficient travel length can achieve the purpose of better physical exercise. The combination of the number of reciprocations, speed and amplitude can reflect the best data of the physical exercise effect of the rowing machine, that is, effective exercise data. However, the existing rowing machine cannot monitor the number of reciprocations, so that one of the three data cannot be reflected, and thus it is impossible to effectively monitor the physical exercise through effective reciprocation. Summary of the invention

[0003] The object of the present invention is to provide a frame and a monitoring component of a rowing machine in view of the above problems.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A frame and monitoring component of a rowing machine, the rowing machine includes a transmission mechanism and a braking mechanism, the transmission mechanism includes a coaxially arranged coil spring box, a pulley, and a belt pulley, the frame includes a main frame portion located at the rear side, a support frame portion located at the front side, and a seat frame portion located at the bottom, the two ends of the support frame portion are respectively connected to the main frame portion and the bottom end of the support frame portion, the upper ends of the main frame portion and the support frame portion are connected, the top of the frame is provided with a hanger for installing the transmission mechanism, the two ends of the main shaft for sleeved with the coil spring box, the pulley, and the pulley are passed through the hanger, the monitoring component includes a grating disk sleeved on the main shaft and a photoelectric coupler arranged on the frame and cooperating with the grating disk, the grating disk is synchronized with the coil spring box, the pulley, and the belt pulley Rotation; a transverse frame groove is opened on the top of the main frame part, and the hanger includes a top frame plate and side hanging plates connected to both sides of the top frame plate, the top frame plate is mounted on the frame groove, and the two ends of the main shaft can be lifted and lowered on the side hanging plates through lifting and adjusting connecting pieces, the lifting and adjusting connecting pieces include a fixed ear plate turned outward relative to the side hanging plates, a movable plate for sleeved on the main shaft and an adjusting connecting piece connected between the fixed ear plate and the movable plate, a movable ear plate parallel to the fixed ear plate is provided on the movable plate, and the lower end of the adjusting connecting piece is connected to the movable ear plate, and the braking mechanism includes an electromagnetic wheel located obliquely below the transmission mechanism and close to one side of the main frame plate rod, and the electromagnetic wheel is connected to the pulley by a belt.

[0006] The part of the main shaft extending out of the movable plate is locked on the movable plate by a locking member such as a locking bolt, and the adjusting connecting member can make the movable plate move up and down with the main shaft along the axial direction of the adjusting connecting member relative to the fixed ear plate. Since the brake mechanism and the transmission mechanism are connected by a belt, the tension of the belt needs to be adjusted when installing the rowing machine to ensure the synchronization and restraint effect between the two to achieve a better exercise effect and improve the controllability of various data. In addition, after a period of use, the belt may slip or loosen during use due to its own ductility. The existing method is to directly replace the belt or set a rotating pressure rod on the middle section of the corresponding belt on the frame to press on the belt. The cost of replacing the belt is high and the disassembly and assembly are troublesome. The pressure rod pressing method not only increases the complex structure, but also adds a stress point on the belt, which makes the belt more easily worn, and may also cause greater vibration and bounce to affect the transmission of the belt.

[0007] The present application adopts the above-mentioned structural coordination method, which reduces the accuracy requirements of the frame part used to install the entire transmission mechanism, facilitates the tension adjustment of the belt and saves costs, and can appropriately adjust the height of the entire transmission mechanism to be more suitable for the efficient operation of the rowing machine and reduce useless losses. For example, the height of the transmission mechanism determines the height of the pull belt on the pulley, which also affects the stress condition of the pull belt to a certain extent.

[0008] The present application can not only monitor the rotation speed of the rowing machine, but also determine the rotation speed and stroke in each direction of the rowing machine through the cooperation of the grating disk and the photoelectric coupler that rotate synchronously with the spring box, the pulley, and the belt pulley. It can also accurately determine the user's effective exercise time and exercise consumption through the combination of the number of reciprocating times, speed and amplitude.

[0009] Preferably, the pulley is arranged between the pulley and the spring box, the spring box includes an inner half box close to the pulley and an outer half box located outside, the outer side of the outer half box extends outwardly to form a grating disk, the photoelectric coupler is provided with through slots with front, rear and top openings, and the grating disk is inserted into the through slots. The spring box is used to house the spring, and the grating is directly connected to the cover of the spring box. The structure is simpler, easy to install and low in cost. The main shaft can be connected to the spring box, the pulley and the pulley through the bearing, and no other connection structure or connection parts are required to sleeve the grating. The grating disk rotates completely synchronously with the spring box, the pulley and the pulley, and the monitoring is accurate.

[0010] Preferably, the photoelectric coupler comprises two groups of transmitters and receivers symmetrically arranged front and back, each group of transmitters and receivers comprises a light-emitting component and a light-receiving component relatively arranged on both sides of the grating disk, and the light-emitting component, the light-receiving component and the photoelectric coupler body enclose a through groove.

[0011] The spacing between the two groups of transmitters and receivers of the photoelectric coupler, the spacing between adjacent bars of the grating disk, and the width of each bar are coordinated so that the two groups of transmitters and receivers are always in a state of one group being on and one group being closed after cooperating with the grating disk. When the grating disk rotates, the two groups of transmitters and receivers will continuously change between the two states of on and closed. The direction in which the grating disk rotates can be determined based on which group changes first, so that the direction in which the grating disk rotates, the speed, and the path of rotation in each direction can be accurately monitored. In actual application, the monitoring standard is set on the controller of the rowing machine. For example, the grating disk must rotate a certain number of times in one direction and then a certain number of times in the other direction to be counted as one reciprocating exercise, and those that do not meet the standard will not be counted as one time. Therefore, the effective number of exercises can be accurately determined through the setting of the above structure.

[0012] Preferably, the outer half box includes a cover portion located on the inner side and a grating disk located on the outer side, the outer periphery of the cover portion extends to the side of the frame to form a circle of grating base edge, the grating disk is integrally connected to the grating base edge, and the groove cavity formed by the grating base edge and the outer cover surface of the cover portion is provided with a plurality of radially arranged restraining ribs whose outer ends are connected to the inner wall of the grating base edge; the inner half box is integrally connected to the pulley, the pulley includes a wheel sleeve and a side stop edge, and the cover plate of the inner half box serves as a side stop edge on one side of the pulley. As can be seen from the above, the inner half box is integrally connected to the pulley, and the inner half box and the outer half box are matched and connected, so that the reel box and the pulley rotate completely synchronously from the side, and the reel wheel does not need to be specially connected to the main shaft by an additional bearing member, as long as the main load-bearing component, the pulley, is connected to the main shaft through a bearing, the equipment has fewer parts, a simplified structure, low cost, easy installation, high synchronization, good stability, high monitoring accuracy, and is not prone to error.

[0013] The grating disk is only connected to the thin-walled grid base edge, and is not directly connected to the box cover or cover edge of the outer half box, so that the micro-vibration that may be generated when the outer half box is aligned and matched with the inner half box and the coil spring in the box is rolled up, which is not easy to affect the flatness of the grating disk and the effectiveness of operation and use. The slight vibration that may be affected is also within the acceptable range that does not affect the normal use of the grating disk. At the same time, the setting of the grid base edge and the restraining ribs saves materials and costs while ensuring the stability of the grating disk connected to the outer half box. It can be seen that the above-mentioned structure allows the grating disk to be combined with the coil spring disk to achieve structural simplification, cost savings, and convenient installation. At the same time, it can ensure that the grating disk is strong enough, high in precision, and not easily disturbed by other components when in use, and ensures that the grating disk is flat and not easy to twist during installation and operation, so that the grating disk integrated into the coil spring box also has high stability and can operate effectively for a long time when connected to a through slot with a small width, and is not prone to failure, and also ensures the accuracy and stability of monitoring.

[0014] Preferably, the side hanging plate includes a hollow connecting plate integrally connected to the side of the top frame plate and extending outward and downward, and a vertically arranged side main plate integrally connected to the lower end of the hollow connecting plate, and the fixed ear plate is formed by folding the middle part of the side main plate outward by 90 degrees, and at least a part of the lower part of the side main plate is overlapped and attached to the movable plate, and the bottom end of the part of the side main plate that is attached is lower than the position of the main shaft, and the lower part of the side main plate is provided with a straight slot with an open lower end for passing the main shaft and allowing the main shaft to move up and down, and the lower end of the straight slot is larger than the corresponding cross-sectional width of the main shaft part.

[0015] The design of the inclined hollow connecting plate makes the main frame, which is narrower than the entire transmission mechanism, suitable for the installation of the transmission mechanism without increasing the width. The hollow connecting plate has stable force, high lifting strength, and is not easy to deform at the bending point, ensuring the stability of the transmission mechanism after installation. The downward length of the side main board is long enough to ensure that the movable plate that locks the main shaft has sufficient support force on the inner side, thereby ensuring the stability of the main shaft after installation.

[0016] Preferably, the adjustment connecting member is an adjustment bolt, the fixed ear plate is provided with a frame slot hole which is open on the outside and penetrates up and down for passing the adjustment bolt, the movable ear plate is provided with a through hole or internal threaded hole which penetrates up and down for connecting with the lower end of the adjustment bolt, and the main shaft is provided with a limit ring with a diameter greater than the width of the slot on the inner side of the side main plate. The limit ring is against the side main plate, and the outer side of the side main plate supports the movable plate, so that the inside and outside of the side main plate are compact and balanced, and the structure is stable, which in turn makes the lateral force of the hollow connecting plate small and will not deform at the upper corner.

[0017] The above structure ensures that the equipment components are convenient to disassemble and assemble, and at the same time, the tensioning belt is more convenient to operate. The whole structure is compact, the force is balanced, the stability is good, and the space occupied is small, and the material is economical.

[0018] Preferably, the movable ear plate located on the outside of the grating disk extends along the length direction of the adjusting bolt to form an extended hanging plate, the photoelectric coupler is arranged at the lower end of the extended hanging plate, and the axis of the adjusting bolt intersects with the axis of the main shaft; the side main board is an integrally inclined inclined plate extending to the rear side of the frame and bulging outward in the middle, and the main frame portion includes symmetrically arranged main frame plate rods on both sides, and a top frame plate rod that is integrally connected to the top of the main frame plate rod and is bent in an arc shape in the horizontal direction. The length direction of the main frame plate rod is inclined relative to the direction of gravity, and the side main board is parallel to the main frame plate rod and has the same inclination direction. The design of the above-mentioned architecture is to reasonably design the above-mentioned structure according to the stress conditions of the rowing machine itself so as to be more in line with the use characteristics of the rowing machine itself. The above-mentioned structure is subjected to more uniform and smaller stress during use and is not easily damaged.

[0019] During installation, the center direction of the center grating disk of the photoelectric coupler can be conveniently set and installed. This is not only convenient for installation, but also ensures precise matching between the photoelectric coupler and the grating disk, thereby ensuring the accuracy of the data and preventing deviation and error during use.

[0020] Preferably, the front and rear ends of the top frame plate are extended to form lateral clamping plates, and an empty frame groove is formed between the two pieces of the top frame plate rods, and the lateral clamping plates are inserted into the empty frame groove. The front end of the top frame plate rod is provided with an enlarged connecting ear plate, and the connecting ear plate is welded to the arc-shaped square tube-shaped support frame part; the area on the outer side surface of the top frame plate rod corresponding to the hollow connecting plate is provided with a supporting hook plate with a hook groove at the outer end with the notch facing upward, the plate surface of the supporting hook plate is erected, and the hollow connecting plate is provided with a hook hole for passing through the outer end groove portion of the hook groove, and the inner groove wall surface of the hook groove is a limiting side support wall parallel to the plate surface of the hollow connecting plate.

[0021] The above-mentioned structure allows the top frame plate to be accurately and conveniently placed in the installation position, and can be quickly and accurately limited in both the longitudinal and transverse directions, so that the top frame plate can be firmly positioned and not easily moved even if it is not locked with the main frame by welding or screwing. The present application further effectively limits the top frame plate in the front and rear directions of the frame by hooking the support hook plate with a hook groove with the top frame connecting plate, and at the same time, the inclined top frame connecting plate can have an outward supporting force in the horizontal left and right directions, thereby ensuring that the inclined top frame connecting plate and the side main board are not easily deformed by force during use, ensuring the long-term stable and effective use of the entire hanger, and ensuring the stability and controllability of the height position and installation position of the transmission mechanism.

[0022] Preferably, the support frame comprises an arc-shaped pipe section connected to the main frame, and a straight support pipe section connected below the arc-shaped pipe section. The straight support pipe section is gradually inclined toward the main frame from top to bottom. The lower end of the support pipe section is connected to the horizontal bottom frame. The brake mechanism is installed on the straight tubular bottom frame. The main frame, the support frame and the bottom frame form a pear-shaped closed loop. The lower end of the front part of the support pipe section is connected to the forward-inclined front support foot of the rowing machine. The position of the pulley corresponding to the position of the pulley between the two main frame plate rods is A drawstring guide component is provided, which is detachably connected to the guide frame groove between the main frame plate rods, and at least two guide wheels are provided on the guide frame groove, and the guide frame groove includes a bottom guide plate and guide plates provided at both side ends of the bottom guide plate and extending upward for connecting the guide frame groove with the main frame plate rod, a base connection hole is provided at the upper part of the guide plate, and a locking connection hole is provided at the lower part, and the guide plate is connected to the main frame plate rod by bolts passing through the base connection hole and the locking connection hole.

[0023] The pear-shaped structure is adapted to the use characteristics and stress conditions of the rowing machine itself, making the frame structure simple while having higher strength and more balanced load-bearing on each component.

[0024] The drawstring guide component has a simple structure and is easy to install, and is convenient for determining the guide direction of the drawstring and for buffering the drawstring during use.

[0025] The design of the entire frame structure is to reasonably design the frame according to the stress of the frame itself so as to better meet the use characteristics of the rowing machine itself. The frame is subjected to more uniform and smaller stress during use, and is not easily damaged. The entire frame structure has high strength, better stability, and is safer to use. The integrity of the entire frame structure is better and more concise.

[0026] Preferably, an arc-shaped long groove corresponding to the locking connection hole is opened on the main frame plate rod with the center of the base connection hole as the center, and a tightening bolt that can slide along the arc-shaped long groove hole is passed through the locking connection hole and the arc-shaped long groove, and a plurality of locking holes are arranged on the upper side edge and / or the lower side edge of the arc-shaped long groove, and a locking plate is sleeved on the tightening bolt, and the locking plate is provided with a locking foot that can be inserted into the locking hole.

[0027] Through the arrangement of the above structure, the guide frame groove can rotate around the base connection hole along the arc-shaped long groove, so as to adjust the position relationship of the guide wheel, so as to adjust the path of the pull belt in the guide wheel and the height of the pull belt after it leaves the guide wheel, so as to better adapt to the height of the transmission mechanism that can be raised and lowered, especially the pull belt wheel, and the position of the pull belt can be appropriately adjusted when the transmission mechanism is raised and lowered, so that the equipment can more accurately calculate the effective exercise amount of the exerciser. At the same time, it is also beneficial for users of different heights and arm lengths to use it to effectively exert force and perform efficient exercise.

[0028] In summary, the present invention has the following beneficial effects:

[0029] 1. The present application uses the cooperation of a grating disk and a photoelectric coupler to not only monitor the rotation speed of the rowing machine, but also to determine the rotation speed and stroke in each direction of the rowing machine, thereby accurately determining the user's effective exercise time and exercise consumption by combining the number of reciprocating times, speed and amplitude.

[0030] 2. The frame structure matching method of the present application reduces the precision requirements of the frame part used to install the entire transmission mechanism, facilitates the tension adjustment of the belt, saves costs, and can appropriately adjust the height of the entire transmission mechanism to be more suitable for the efficient operation of the rowing machine, reducing useless losses.

[0031] For example, the height of the transmission mechanism determines the height of the pull belt on the pull wheel, and also affects the stress condition of the pull belt to a certain extent.

[0032] 3. Through the design of this application, the rowing machine designed by the company is not only simple in overall design, low in cost, compact in structure, high in strength, and safe, but can also continuously and efficiently provide effective exercise data to exercisers or instructors, so that users can fully grasp their own exercise progress and plan their own exercise needs based on the data feedback, thereby ensuring the effectiveness and efficiency of the exercise. The frame and monitoring components have good coordination stability and are easy to adjust, thereby ensuring the long-term availability and effectiveness of effective exercise data.

[0033] 4. The overall structure of this application is simple, the humanized design is reasonable, and the operation is convenient and easy, and the cost is low.

[0047] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0048] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0049] Embodiment 1:

[0050] A frame and monitoring component of a rowing machine, the rowing machine includes a transmission mechanism 1 and a braking mechanism, the transmission mechanism includes a coil spring box 2, a pulley 3, and a pulley 4 that are coaxially arranged, the frame includes a main frame portion 51 located on the rear side, a support frame portion 52 located on the front side, and a seat frame portion 53 located at the bottom, the two ends of the support frame portion are respectively connected to the main frame portion and the bottom end of the support frame portion, the upper ends of the main frame portion and the support frame portion are connected, the top of the frame is provided with a hanger 6 for installing the transmission mechanism, the two ends of the main shaft 8 for sleeved with the coil spring box 2, the pulley 3, and the pulley 4 are passed through the hanger, the monitoring component includes a grating disk 71 sleeved on the main shaft and a photoelectric coupler 72 arranged on the frame and matched with the grating disk, the grating disk rotates synchronously with the coil spring box 2, the pulley 3, and the pulley 4.

[0051] The present application can not only monitor the rotation speed of the rowing machine, but also determine the rotation speed and stroke in each direction of the rowing machine through the cooperation of the grating disk and the photoelectric coupler that rotate synchronously with the spring box 2, the pulley 3, and the pulley 4, so as to accurately determine the user's effective exercise time and exercise consumption through the combination of the number of reciprocating times, speed and amplitude.

[0052] A transverse frame groove 511 is opened on the top of the main frame part, and the hanger includes a top frame plate 61 and side hanging plates 62 connected to both sides of the top frame plate. The top frame plate is mounted on the frame groove, and the two ends of the main shaft can be lifted and lowered on the side hanging plates through lifting and adjusting connecting pieces. The lifting and adjusting connecting pieces include a fixed ear plate 63 turned outward relative to the side hanging plates, a movable plate 64 for sleeved on the main shaft and an adjusting connecting piece 65 connected between the fixed ear plate and the movable plate. A movable ear plate 641 parallel to the fixed ear plate is provided on the movable plate, and the lower end of the adjusting connecting piece is connected to the movable ear plate; the braking mechanism includes an electromagnetic wheel 9 located obliquely below the transmission mechanism and close to one side of the main frame plate rod, and the electromagnetic wheel is connected to the pulley through a belt 91.

[0053] The part of the main shaft extending out of the movable plate is locked on the movable plate by a locking member such as a locking bolt, and the adjusting connecting member can make the movable plate move up and down with the main shaft along the axial direction of the adjusting connecting member relative to the fixed ear plate. Since the brake mechanism and the transmission mechanism are connected by a belt, the tension of the belt needs to be adjusted when installing the rowing machine to ensure the synchronization and restraint effect between the two to achieve a better exercise effect and improve the controllability of various data. In addition, after a period of use, the belt may slip or loosen during use due to its own ductility. The existing method is to directly replace the belt or set a rotating pressure rod on the middle section of the corresponding belt on the frame to press on the belt. The cost of replacing the belt is high and the disassembly and assembly are troublesome. The pressure rod pressing method not only increases the complex structure, but also adds a stress point on the belt, which makes the belt more easily worn, and may also cause greater vibration and bounce to affect the transmission of the belt.

[0054] The present application adopts the above-mentioned structural coordination method, which reduces the accuracy requirements of the frame part used to install the entire transmission mechanism, facilitates the tension adjustment of the belt and saves costs, and can appropriately adjust the height of the entire transmission mechanism to be more suitable for the efficient operation of the rowing machine and reduce useless losses. For example, the height of the transmission mechanism determines the height of the pull belt on the pulley, which also affects the stress condition of the pull belt to a certain extent.

[0055] Embodiment 2:

[0056] The difference from the above embodiment is that the pulley is arranged between the pulley and the spring box, the spring box includes an inner half box 21 close to the pulley and an outer half box 22 located outside, the outer side of the outer half box extends outwardly to form a grating disk, and the photoelectric coupler is provided with through slots 721 with front, rear and top openings, and the grating disk is inserted into the through slots. The spring box is used to house the spring, and the grating is directly connected to the cover of the spring box. The structure is simpler, easy to install and low in cost. The main shaft can be connected to the spring box 2, the pulley 3 and the pulley 4 through the bearing, and no other connection structure or connection parts are required to sleeve the grating. The grating disk rotates completely synchronously with the spring box 2, the pulley 3 and the pulley 4, and the monitoring is accurate.

[0057] Embodiment three:

[0058] The difference from the above embodiment is that the photoelectric coupler includes two groups of transmitters and receivers symmetrically arranged front and back, each group of transmitters and receivers includes a light-emitting component 722 and a light-receiving component 723 that are relatively arranged on both sides of the grating disk, and the light-emitting component, the light-receiving component and the photoelectric coupler body are surrounded to form a through groove.

[0059] The spacing between the two groups of transmitters and receivers of the photoelectric coupler, the spacing between adjacent bars of the grating disk, and the width of each bar are coordinated so that the two groups of transmitters and receivers are always in a state of one group being on and one group being closed after cooperating with the grating disk. When the grating disk rotates, the two groups of transmitters and receivers will continuously change between the two states of on and closed. The direction in which the grating disk rotates can be determined based on which group changes first, so that the direction in which the grating disk rotates, the speed, and the path of rotation in each direction can be accurately monitored. In actual application, the monitoring standard is set on the controller of the rowing machine. For example, the grating disk must rotate a certain number of times in one direction and then a certain number of times in the other direction to be counted as one reciprocating exercise, and those that do not meet the standard will not be counted as one time. Therefore, the effective number of exercises can be accurately determined through the setting of the above structure.

[0060] Embodiment 4:

[0061] The difference from the above embodiment is that the outer half box includes a box cover part 221 located on the inner side and a grating disk located on the outer side, the outer periphery of the box cover part extends laterally to the frame to form a circle of grid base edge 222, the grating disk is integrally connected to the grid base edge, and the groove cavity formed by the grid base edge and the outer cover surface of the box cover part is provided with restraining ribs 223 which are mostly radially arranged and the outer ends are connected to the inner wall of the grid base edge; the inner half box is integrally connected to the pulley, the pulley includes a wheel shaft sleeve 31 and a side stop edge 32, and the cover plate 211 of the inner half box serves as a side stop edge on one side of the pulley. It can be seen from the above that the inner half box is connected to the pulley as a whole, and the inner half box and the outer half box are connected in a cooperative manner, so that the reel box and the pulley rotate completely synchronously from the side. At the same time, the reel wheel does not need to adopt additional bearing parts to be connected with the main shaft. It only needs the main load-bearing component, the pulley, to be connected with the main shaft through the bearing. The equipment has fewer parts, a simpler structure, low cost, easy installation, high synchronization, good stability, high monitoring accuracy, and is not prone to errors.

[0062] The grating disk is only connected to the thin-walled grid base edge, and is not directly connected to the box cover or cover edge of the outer half box, so that the micro-vibration that may be generated when the outer half box is aligned and matched with the inner half box and the coil spring in the box is rolled up, which is not easy to affect the flatness of the grating disk and the effectiveness of operation and use. The slight vibration that may be affected is also within the acceptable range that does not affect the normal use of the grating disk. At the same time, the setting of the grid base edge and the restraining ribs saves materials and costs while ensuring the stability of the grating disk connected to the outer half box. It can be seen that the above-mentioned structure allows the grating disk to be combined with the coil spring disk to achieve structural simplification, cost savings, and convenient installation. At the same time, it can ensure that the grating disk is strong enough, high in precision, and not easily disturbed by other components when in use, and ensures that the grating disk is flat and not easy to twist during installation and operation, so that the grating disk integrated into the coil spring box also has high stability and can operate effectively for a long time when connected to a through slot with a small width, and is not prone to failure, and also ensures the accuracy and stability of monitoring.

[0063] Embodiment five:

[0064] The difference from the above embodiment is that the side hanging plate includes a hollow connecting plate 621 extending outward and downward and integrally connected to the side of the top frame plate, and a vertically arranged side main plate 622 integrally connected to the lower end of the hollow connecting plate. The fixed ear plate is formed by folding the middle part of the side main plate outward by 90 degrees. At least part of the lower part of the side main plate is overlapped with the movable plate and the bottom end of the part of the side main plate that is in contact is lower than the position of the main shaft. The lower part of the side main plate is provided with a straight slot 6221 with an open lower end for passing the main shaft and allowing the main shaft to move up and down, and the lower end of the straight slot is larger than the corresponding cross-sectional width of the main shaft part.

[0065] The design of the inclined hollow connecting plate makes the main frame, which is narrower than the entire transmission mechanism, suitable for the installation of the transmission mechanism without increasing the width. The hollow connecting plate has stable force, high lifting strength, and is not easy to deform at the bending point, ensuring the stability of the transmission mechanism after installation. The downward length of the side main board is long enough to ensure that the movable plate that locks the main shaft has sufficient support force on the inner side, thereby ensuring the stability of the main shaft after installation.
