Description

Technical Field

[0001] The utility model belongs to clothing ironing equipment, and specifically relates to a locking mechanism for locking an ironing board in a required posture, an ironing board angle adjusting mechanism, and a hanging ironing machine. Background Art

[0002] In order to be suitable for different ironing requirements, the inclination angle of the ironing board is configured to be variable and can be positioned in the required posture. Positioning the ironing board in the required posture depends on the locking mechanism. A locking mechanism that is simple in structure, reliable in locking, easy to operate, and can lock the ironing board in a flat position, an upright position, and any inclination angle between the flat position and the upright position is required for such an ironing board. Summary of the Utility Model

[0003] The technical problem to be solved and the technical task proposed by the utility model are to overcome the defects of the existing locking mechanism, such as complex structure, unreliable locking, and inconvenient operation, and to provide a locking mechanism, an ironing board angle adjusting mechanism, and a hanging ironing machine that are simple in structure, reliable in locking, easy to operate, and can lock the ironing board in a flat position, an upright position, and any inclination angle between the flat position and the upright position.

[0004] To achieve the above object, the locking mechanism of the utility model includes:

[0005] A first sliding rod;

[0006] A first locking member, which is sleeved on the first sliding rod through a through hole so that the first sliding rod can slide in the through hole, and the first locking member locks the first sliding rod in a first direction by a first elastic force to prevent the first sliding rod from moving;

[0007] A second sliding rod;

[0008] A second locking member, which is sleeved on the second sliding rod through a through hole so that the second sliding rod can slide in the through hole, and the second locking member locks the second sliding rod in a second direction by a second elastic force to prevent the second sliding rod from moving in the second direction;

[0009] An unlocking member, which is in linkage cooperation with a handle, the first locking member, and the second locking member;

[0010] Wherein, operating the handle to link the unlocking member, the first locking member, and the second locking member simultaneously causes the first locking member to overcome the first elastic force to unlock the first sliding rod and allow the first sliding rod to move, and the second locking member to overcome the second elastic force to unlock the second sliding rod and allow the second sliding rod to move.

[0011] This locking mechanism locks the first sliding rod and the second sliding rod independently, has low requirements for the manufacturing and assembly precision of the two locking members, and does not rely on the cooperation relationship between the two locking members for locking the first sliding rod and the second sliding rod, avoiding mutual influence between the two locking members, and being beneficial to manufacturing and assembly.

[0012] The locking mechanism locks the first slide bar and the second slide bar in different directions, and the locking is comprehensive and reliable.

[0013] The locking mechanism is sleeved on the corresponding sliding rod through the through hole to lock the sliding rod. The sliding rod can be locked at any position within its sliding range. There is no need to deliberately find the gear position during operation, and positioning and locking are easy.

[0014] The locking mechanism locks the slide bar by elastic force, and does not loosen or shake in the locked state, and the locking is reliable. The two slide bars can be unlocked at the same time by operating the handle to link the unlocking member and the two locking members, and the operation is easy.

[0015] The locking mechanism has few parts, is compact and has a simple structure.

[0016] Preferably, the first locking member locks the first slide bar and the second locking member locks the second slide bar by the edge of the through hole clamping the corresponding slide bar, and the first locking member unlocks the first slide bar and the second locking member unlocks the second slide bar by the edge of the through hole releasing the corresponding slide bar. Therefore, locking and unlocking can be achieved by causing the corresponding locking member to change its posture, and the structure is simple and compact. In particular, the position where the locking member locks the slide bar and the position where it unlocks the slide bar are almost critical, and the locking and unlocking actions are sensitive.

[0017] Preferably, the first locking member and the second locking member are both rigid members, the first elastic force is provided by a first locking spring acting on the first locking member, and the second elastic force is provided by a second locking spring acting on the second locking member. Accordingly, the locking member can provide a larger locking force to avoid locking failure caused by deformation of the locking member.

[0018] Preferably, the first locking member and the second locking member are both assembled by swinging the pin at one end thereof. Thus, the position of the locking member is ensured, and the elastic force of appropriate size is received, and locking or unlocking can be achieved through a small swing amplitude, thereby avoiding the locking failure caused by the locking member being out of position.

[0019] Preferably, the first slide bar is parallel to the second slide bar and arranged side by side, so that the first direction is opposite to the second direction, that is, the two slide bars are locked in opposite directions at the same time, ensuring reliable locking.

[0020] In one embodiment, the unlocking member is a swing rod that is simultaneously linked to the handle, the first locking member and the second locking member. Accordingly, two locking members can be unlocked simultaneously by one unlocking member, the structure is compact, and the unlocking action is synchronized.

[0021] Preferably, the unlocking member is located between the first locking member and the second locking member. The unlocking member swings around the axis of its middle part, so that the two ends of the unlocking member apply unlocking driving forces in different directions to the first locking member and the second locking member respectively, ensuring synchronous unlocking actions. In particular, when the two locking members are unlocked simultaneously by the unlocking member, the unlocking member is evenly stressed and is not easily deformed or displaced after long-term use. Moreover, such unlocking driving forces have damping and buffering effects on the unlocking and locking of the sliding rod, and will not cause out-of-control due to sudden unlocking or sudden locking.

[0022] In one embodiment, the unlocking member includes a first unlocking member and a second unlocking member. The first unlocking member is linked with the handle and the first locking member, and the second unlocking member is linked with the handle and the second locking member. Accordingly, different locking members are unlocked by different unlocking members respectively, and the unlocking force provided by each unlocking member during unlocking is small, ensuring the durability of the unlocking member.

[0023] Preferably, the locking mechanism further includes a linkage member, which is connected between the handle and the unlocking member to realize the linkage between the handle and the unlocking member. Accordingly, it is not necessary to directly connect the handle to the unlocking member and limit the position of the handle adjacent to the unlocking member, and the handle can be arranged at a position that is easy to operate as required.

[0024] In one embodiment, the linkage member is a rigid rod, and the linkage member transmits a pulling force or a pushing force between the handle and the unlocking member to realize the linkage between the handle and the unlocking member. Accordingly, the linkage member can transmit accurate and sensitive unlocking forces.

[0025] In another embodiment, the linkage member is a cable, and the linkage member transmits a pulling force between the handle and the unlocking member to realize the linkage between the handle and the unlocking member. Accordingly, it is convenient to arrange the linkage member and reduce the occupied position of the linkage member.

[0026] Preferably, a return spring acts on the handle, which is used to assist the handle to return after the handle is operated.

[0027] Preferably, the first locking member, the second locking member and the unlocking member are located in a fixed box, ensuring the cooperation between the locking member and the unlocking member and avoiding interference by external factors.

[0028] The locking mechanism of the present invention is preferably applied to the ironing board angle adjustment mechanism, and the ironing board angle adjustment mechanism includes:

[0029] An ironing board;

[0030] An angle adjustment mechanism, which is assembled with the ironing board and is used to adjust the inclination angle of the ironing board by deformation;

[0031] The locking mechanism of the present utility model prevents the angle adjustment mechanism from deforming to fix the inclination angle of the ironing board when the first locking member locks the first sliding rod and the second locking member locks the second sliding rod, and allows the angle adjustment mechanism to deform to adjust the inclination angle of the ironing board when the first locking member unlocks the first sliding rod and the second locking member unlocks the second sliding rod.

[0032] In view of this, the ironing board is adjusted to the required inclination angle by the angle adjustment mechanism, and the ironing board is positioned at the required inclination angle by the locking mechanism. Moreover, according to the functions and effects of the aforementioned locking mechanism, the angle adjustment and positioning of the ironing board are both easy to operate, and the ironing board has a stable posture and a large bearing capacity after being positioned.

[0033] Preferably, the first sliding rod and the second sliding rod are arranged on the back of the ironing board and extend along the length direction of the ironing board, and one end of the first sliding rod and the second sliding rod is configured to move along the length direction of the ironing board; the unlocking member, the first locking member and the second locking member are located on the back of the ironing board. This ensures that the ironing board has a regular shape, occupies a small space, and does not affect ironing.

[0034] Preferably, the first locking member, the second locking member and the unlocking member are located in the middle part of the back of the ironing board. It is easy to arrange the locking mechanism relative to the ironing board, so that the locking mechanism can reliably lock the ironing board.

[0035] The ironing board is provided with a track extending along its length direction, and one end of the first sliding rod and the second sliding rod is configured to move along the track. This ensures the synchronization and flexibility of the actions of the first sliding rod and the second sliding rod.

[0036] Preferably, the track includes a first guide rail and a second guide rail, the first guide rail and the second guide rail are symmetrically arranged on two edges of the ironing board, the rear ends of the first sliding rod and the second sliding rod are commonly connected to a moving shaft, one end of the moving shaft is in sliding fit with the first guide rail, and the other end of the moving shaft is in sliding fit with the second guide rail. Accordingly, the two sliding rods and the moving shaft form the support and positioning of the ironing board.

[0037] The preferred handle is located on the back of the ironing board or on the edge of the ironing board, and the unlocking member is swingably assembled via a shaft perpendicular to the ironing board. Accordingly, the handle can be arranged at an easily operable position as required.

[0038] The ironing board angle adjustment mechanism of the present utility model is preferably applied to a hanging ironing machine, and the hanging ironing machine includes:

[0039] The ironing board angle adjustment mechanism of the present utility model;

[0040] A support structure that supports the angle adjustment mechanism to support the ironing board;

[0041] A main body for providing steam for ironing clothes.

[0042] Accordingly, when using steam to iron clothes, the ironing board can be adjusted and positioned as needed. Moreover, the operation is convenient.

[0043] In this utility model, two sliding rods and two locking parts are configured. Each locking part is sleeved on a corresponding sliding rod through its through hole and locks the corresponding sliding rod by elastic force. The locking directions of the two sliding rods are opposite; and by operating the handle to link the unlocking part and the two locking parts, the two sliding rods are unlocked simultaneously. This independent locking of the two sliding rods in different directions has low requirements for the manufacturing and assembly accuracy of the two locking parts. The locking of the first sliding rod and the second sliding rod does not depend on the cooperation relationship of the two locking parts, avoiding mutual influence between the two locking parts, facilitating manufacturing and assembly, and ensuring comprehensive and reliable locking. The sliding rod can be locked at any position within its sliding range. When operating, there is no need to deliberately find a gear position, and it is easy to position and lock. The sliding rod is locked by elastic force, and it does not loosen or shake in the locked state, with reliable locking. By operating the handle to link the unlocking part and the two locking parts to unlock the two sliding rods simultaneously, it is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] In the description of the present utility model, it should be understood that the technical features defined by terms such as "first", "second", etc. with a sequential concept are only for clearly describing the defined technical features so that the defined technical features can be clearly distinguished from other technical features, rather than representing such naming in actual implementation. Therefore, it should not be construed as a limitation to the present utility model.

[0086] The present utility model will be introduced in detail below in conjunction with specific embodiments and drawings.

[0087] The ironing board adjusting mechanism of an embodiment of the present utility model is shown in Figures 1 to 5 and the locking mechanism of the present utility model will be described in the description of the ironing board adjusting mechanism.

[0088] As Figures 1 to 5 shown, the ironing board adjusting mechanism includes an ironing board 210, an angle adjusting mechanism 220, and a locking mechanism 100.

[0089] The ironing board 210 is integrally plate-shaped and is preferably made of plastic. The ironing board 210 can be either an integral mechanism or an assembled structure. In order to increase the strength of the ironing board and reduce its weight, through holes are provided on the ironing board, ribs are provided on the back of the ironing board, and side edges are provided on the edge of the ironing board. The through holes therein can increase the steam permeability. When ironing, a cloth cover can be put on the ironing board. First guide rail 211 and second guide rail 212 are respectively assembled on both side edges of the ironing board, and the first guide rail and the second guide rail are symmetrically distributed to form a track.

[0090] The angle adjusting mechanism 220 includes a base frame 221 and a connecting rod 222. The base frame 221 is rotatably connected to the ironing board 210 via a first shaft a. The base frame 221 is rotatably connected to the first end of the connecting rod 222 via a second shaft b. The second end of the connecting rod 222 is in sliding fit with the track of the ironing board via a moving shaft c. In the illustrated structure, the left end of the moving shaft c is in sliding fit with the first guide rail 211, and the right end of the moving shaft c is in sliding fit with the second guide rail 212. The axial (left - right direction) projection point A of the first shaft a, the axial projection point B of the second shaft, and the axial projection point C of the moving shaft are respectively located at the vertices of a triangle ABC, wherein the ironing board rotates around the first shaft a to adjust its inclination angle, and the rotation of the ironing board around the first shaft a causes the connecting rod 122 to rotate around the second shaft b and the moving shaft c to slide along the track 111 to change the shape of the triangle ABC.

[0091] Based on this angle adjusting mechanism, the position of the first side AB of the triangle determined by the first shaft a and the second shaft b is fixed and the length remains unchanged. The length of the second side BC of the triangle determined by the second shaft b and the moving shaft c remains unchanged and the position can change. The length and position of the third side AC of the triangle determined by the first shaft a and the moving shaft c will both change. In Figure 3 the moving shaft c is located at the right end of the ironing board and the ironing board is in a horizontal state. FromFigure 3 In the state shown, the ironing board can be rotated counterclockwise about the first axis a to reach Figure 4 the inclined state shown and Figure 5 the upright state shown. When the ironing board changes from the state shown in Figure 3 to the state shown in Figure 4 and then to the state shown in Figure 5 , the moving shaft c moves along the track from the right end of the ironing board to the middle position of the ironing board. Conversely, when the ironing board changes from the state shown in Figure 5 to the state shown in Figure 4 and then to the state shown in Figure 3 , the moving shaft c moves along the track from the middle position of the ironing board to the right end of the ironing board. Accordingly, the ironing board is in an upright, flat, and any inclined angle between the upright and the flat states as the shape of triangle ABC changes.

[0092] To increase the moving flexibility of the moving shaft c and the track 111, bearings are installed at both ends of the moving shaft, and the bearings are located in the corresponding grooved first guide rail and second guide rail. In particular, the two guide rails are configured such that when the ironing board is flat, both ends of the moving shaft are limited to one end of the guide rail, whereby the flipping range of the ironing board from the upright to the horizontal direction can be restricted, which is conducive to accurately adjusting the ironing board to the horizontal state, that is, when the ironing board flips from the upright to the horizontal direction, until its flipping is blocked, it means that it has flipped to the horizontal state.

[0093] In the illustrated structure, the base frame 221 has a support portion 2211, a first extension portion 2212, and a second extension portion 2213. The first extension portion 2212 extends forward from the support portion 2211, and the second extension portion 2213 extends backward from the support portion 2211. The first axis a is located on the first extension portion 2212, and the second axis b is located on the second extension portion 2213. When the ironing board is flat, the first axis a is located on the front side of the support portion 2211, and the moving shaft c is located on the rear side of the support portion 2211, whereby the center of gravity of the ironing board is ensured to be as close as possible to the support portion 2211, making the ironing board stable. The first extension portion 2212 is higher than the second extension portion 2213. The connecting rod is in an isosceles trapezoid shape and has a hollow middle portion, and the hollow middle portion serves as an avoidance portion. When the ironing board is upright, the upper end of the support portion 2211 is located in the avoidance portion, which can reduce the occupied volume. Both the first axis a and the moving shaft c are connected to the back surface of the ironing board 210. When the ironing board is upright, its front face faces forward, and when the ironing board is flat, its front face faces upward. Based on the horizontal plane, the inclination angle of the flat ironing board is 0 degrees, the inclination angle of the upright ironing board is 90 degrees, and the inclination angle of the ironing board can be adjusted arbitrarily between 0 - 90 degrees.

[0094] The aforementioned ironing board adjusts the tilt angle of the ironing board 210 through the deformation of the angle adjustment mechanism 220. The deformation of the angle adjustment mechanism 220 is reflected in the deformation of triangle ABC. Therefore, when the ironing board is adjusted to any posture, fixing triangle ABC, that is, preventing the deformation of the angle adjustment mechanism 220, can fix the tilt angle of the ironing board. Preventing the deformation of the angle adjustment mechanism 220 is achieved by the locking mechanism 100.

[0095] As Figures 6 - 7 shown, the locking mechanism 100 is assembled on the back of the ironing board 210. The locking mechanism is used to lock and fix triangle ABC to fix the ironing board at the required angle. In Figures 3 - 5 the structure shown, the locking mechanism prevents the deformation of the triangle by preventing the change in the length of side AC of triangle ABC.

[0096] Specifically, as Figures 8 - 17 shown, the locking mechanism 100 includes a first sliding rod 110, a first locking member 120, a second sliding rod 130, a second locking member 140, an unlocking member 150 and a handle 160.

[0097] The first sliding rod 110 and the second sliding rod 130 are parallel and arranged side by side for jointly connecting to the ironing board. As described below, the first sliding rod 110 and the second sliding rod 130 are connected to the ironing board through a moving shaft c.

[0098] The first locking member 120 is sleeved on the first sliding rod 110 through a through hole so that the first sliding rod can slide in the through hole. The first locking member 120 locks the first sliding rod 110 in the first direction (rightward) by means of a first elastic force to prevent the first sliding rod from moving. The second locking member 140 is sleeved on the second sliding rod 130 through a through hole so that the second sliding rod can slide in the through hole. The second locking member 140 locks the second sliding rod 130 in the second direction (leftward) by means of a second elastic force to prevent the second sliding rod from moving in the second direction. Moreover, the first locking member 120 locking the first sliding rod 110 and the second locking member 140 locking the second sliding rod 130 are both that the edge of the through hole on the locking member catches the corresponding sliding rod, and the unlocking of the first sliding rod by the first locking member and the unlocking of the second sliding rod by the second locking member are both that the edge of the through hole on the locking member releases the corresponding sliding rod. Both the first locking member 120 and the second locking member 140 are rigid members. The first elastic force is provided by a first locking spring 121 acting on the first locking member 120, and the second elastic force is provided by a second locking spring 141 acting on the second locking member 140.

[0099] In the natural state, as Figure 13As shown, the first locking member 120 is tilted to the right under the elastic force of the first locking spring 121, and the edge of the through hole on the first locking member 120 catches the first sliding rod 110 to generate a locking force. At this time, if an external force is applied to the first sliding rod 110 to move it to the right, under the action of the locking force, the tendency of the first locking member to tilt to the right will increase, increasing the locking force, so as to achieve the purpose of preventing the first sliding rod from moving to the right. Moreover, the greater the external force that urges the first sliding rod to move to the right, the greater the locking force. Therefore, reliable locking of the first sliding rod moving to the right (the first direction) is achieved. On the contrary, at this time, if an external force is applied to the first sliding rod 110 to move it to the left, under the action of the locking force, it will cause the first locking member 120 to have a tendency to tilt to the left, reducing the locking force. The greater the external force that urges the first sliding rod to move to the left, the greater the reduction in the locking force, until the external force can overcome the locking force, and the first sliding rod will move to the left.

[0100] Similarly, in the natural state, as Figure 10 shown, the second locking member 140 is tilted to the left under the elastic force of the second locking spring 141, and the edge of the through hole on the second locking member 140 catches the second sliding rod 130 to generate a locking force. At this time, if an external force is applied to the second sliding rod 130 to move it to the left, under the action of the locking force, the tendency of the second locking member 140 to tilt to the left will increase, increasing the locking force, so as to achieve the purpose of preventing the second sliding rod from moving to the left. Moreover, the greater the external force that urges the second sliding rod to move to the left, the greater the locking force. Therefore, reliable locking of the second sliding rod moving to the left (the second direction) is achieved. On the contrary, at this time, if an external force is applied to the second sliding rod to move it to the right, under the action of the locking force, it will cause the second locking member to have a tendency to tilt to the right, reducing the locking force. And the greater the external force that urges the second sliding rod to move to the right, the greater the reduction in the locking force, until the external force can overcome the locking force, and the second sliding rod will move to the right.

[0101] As described above, in view of the fact that the locking directions of the first sliding rod and the second sliding rod are opposite, therefore, when the first sliding rod and the second sliding rod are locked simultaneously, the external force applied to either sliding rod to urge it to move, due to the blocking of the other sliding rod, cannot cause either sliding rod to move. Based on this, reliable locking is achieved.

[0102] When unlocking, overcome the elastic force of the first locking spring 121 and Figure 13 right the first locking member 120 in Figure 15 the state shown, then the edge of the through hole of the first locking member releases the first sliding rod 110. Overcome the elastic force of the second locking spring 141 and Figure 10 right the second locking member in Figure 14 the state shown, then the edges of the through holes of the second locking member release the second sliding rod. At this time, the external forces applied to the two sliding rods to urge the two sliding rods to move will cause the two sliding rods to move left and right in the corresponding through holes, realizing the unlocking of the two sliding rods.

[0103] Among them, the unlocking member 150 is in linkage cooperation with the handle 160, the first locking member 120, and the second locking member 140; operating the handle 160 links the unlocking member 150, the first locking member 120, and the second locking member 140 to simultaneously cause the first locking member to overcome the first elastic force to unlock the first sliding rod 110 and allow the first sliding rod to move, and the second locking member 140 to overcome the second elastic force to unlock the second sliding rod 130 and allow the second sliding rod to move. Specifically, the unlocking member 150 is a swing rod that is simultaneously linked to the handle, the first locking member, and the second locking member. The unlocking member 150 is located between the first locking member 120 and the second locking member 140. The unlocking member 150 Figure 12 、 Figures 16 - 17 swings around the axis 151 at its middle part as shown, so that both ends of the unlocking member apply unlocking driving forces in different directions to the first locking member and the second locking member respectively.

[0104] As Figure 9 、 Figure 11 、 Figures 16 - 17 shown, the locking mechanism further includes a linkage member 170. The linkage member is a rigid rod. The linkage member 170 is connected between the handle 160 and the unlocking member 150 to transmit a tensile force or a thrust force to achieve the linkage between the handle and the unlocking member. Refer to Figures 16 - 17 , when operating the handle, the linkage member causes the unlocking to swing as shown by the arrow in Figure 17 . The left end of the unlocking member applies a forward unlocking driving force to the first locking member, and the right end of the unlocking member applies a backward unlocking driving force to the second locking member, unlocking both sliding rods simultaneously. A return spring 161 acts on the handle 160 to reset the handle after releasing the handle.

[0105] In view of the structure and assembly method of the unlocking member, in other embodiments, changing the assembly method of the linkage member 170 can also achieve the linkage between the handle and the unlocking member by the linkage member transmitting a tensile force.

[0106] In other embodiments, the linkage member can also be a cable, and the linkage member transmits a tensile force between the handle and the unlocking member to achieve the linkage between the handle and the unlocking member.

[0107] In other embodiments, the unlocking member can include a first unlocking member and a second unlocking member. The first unlocking member is linked to the handle and the first locking member, and the second unlocking member is linked to the handle and the second locking member. Then operating the handle can also simultaneously link the first locking member and the second locking member to unlock.

[0108] In the illustrated structure, the first locking member 120, the second locking member 140, and the unlocking member 150 are located in a fixed box 180. The box 180 includes a base 181 and a cover 182. The first locking member 120 and the second locking member 140 are respectively swingably assembled to the corresponding bearing parts 183 through the first pin shaft 122 and the second pin shaft 142 at one end of each of them. As Figure 16As shown, the bearing portion 183 is an arc-shaped groove provided in the base 181. When the cover and the base are assembled together, the pin shaft is pressed against the bearing portion.

[0109] In view of the aforementioned angle adjustment mechanism 220, the locking mechanism 100 is applied to the angle adjustment mechanism in the following manner: The base 180 of the box is fixed to the middle part of the back surface of the ironing board 210, so that the unlocking member 150, the first locking member 120, and the second locking member 140 are located at the middle part of the back surface of the ironing board 210. Moreover, the first sliding rod 110 and the second sliding rod 130 are arranged on the back surface of the ironing board 210 and extend along the length direction of the ironing board. The rear ends of the first sliding rod 110 and the second sliding rod 130 are jointly connected to the moving shaft c. By the movement of the moving shaft c along the track, the rear ends of the first sliding rod and the second sliding rod move along the length direction of the ironing board. The handle 160 is located on the back surface of the front end of the ironing board 210. In other embodiments, the handle can be arranged on any edge of the ironing board. The shaft 151 for swingably assembling the unlocking member 150 is perpendicular to the ironing board 210.

[0110] In view of the above structure, when the first locking member 120 locks the first sliding rod 110 and the second locking member 140 locks the second sliding rod 130, it prevents the angle adjustment mechanism 220 from deforming to fix the inclination angle of the ironing board. When the first locking member unlocks the first sliding rod and the second locking member unlocks the second sliding rod, it allows the angle adjustment mechanism to deform to adjust the inclination angle of the ironing board.

[0111] As described above, the inclination angle of the ironing board is adjusted by the deformation of triangle ABC, and when adjusting the deformation of triangle ABC, it is achieved by the position change caused by the movement of the moving shaft c along the track. In the locked state, the two sliding rods are locked, and the moving shaft cannot move along the track, and the ironing board is fixed at the required inclination angle. When it is necessary to adjust the inclination angle of the ironing board, operate the handle, unlock the two locking members, allow the two sliding rods to move, flip the ironing board, then the moving shaft moves along the track to achieve the angle adjustment of the ironing board. After the adjustment is completed, release the handle, and the ironing board can be locked and positioned.

[0112] In other embodiments, the angle adjustment mechanism can also be other deformable structural forms. Similarly, this locking mechanism is used to prevent the angle adjustment mechanism from deforming to fix the inclination angle of the ironing board and allow the angle adjustment mechanism to deform to adjust the inclination angle of the ironing board.

[0113] Figure 18An embodiment of the foregoing ironing board angle adjustment mechanism applied to a hanging iron is shown. The hanging iron 300 includes a support structure 310, a main body 320, an ironing terminal 330, and an ironing board angle adjustment mechanism 200. The support structure includes a base 311 and a support rod 312. The support rod 312 supports the base frame 221 of the angle adjustment mechanism 220 to support the ironing board. The main body 320 is connected to the ironing terminal 330, such as an iron or a steam nozzle, through a hose. The steam generated by the main body is conveyed to the ironing terminal through the hose, and the steam is ejected from the ironing terminal to iron clothes.

[0114] The foregoing ironing board angle adjustment mechanism can also be applied to an ironing board with adjustable angle. Omitting Figure 18 the main body, the hose, and the ironing terminal in it, the remaining mechanism is an ironing board with adjustable angle, which will not be elaborated herein.

[0115] As described above, in view that the locking mechanism locks the first sliding rod and the second sliding rod independently, the manufacturing and assembly accuracy requirements for the two locking parts are low. The locking of the first sliding rod and the second sliding rod does not need to rely on the cooperation relationship between the two locking parts, avoiding the mutual influence between the two locking parts, which is beneficial to manufacturing and assembly. Since the first sliding rod and the second sliding rod are locked in different directions, the locking is comprehensive and reliable. Since the sliding rod is locked by sleeving through the through hole on the corresponding sliding rod, the sliding rod can be locked at any position within its sliding range, and there is no need to deliberately find a gear during operation, and the positioning and locking are easy. Since the sliding rod is locked by elastic force, it does not loosen or shake in the locked state, and the locking is reliable. By operating the handle to link the unlocking part and the two locking parts to unlock the two sliding rods simultaneously, it is easy to operate. The locking mechanism has few parts and is compact, and the structure is simple.
