Description

Technical Field

[0001] The utility model belongs to the field of guiding structures, and particularly relates to a guiding and limiting part and a linkage mechanism. Background Art

[0002] When a working component moves, it is often necessary to set a guiding structure to guide the movement of the working component, so as to ensure that the working component moves according to a predetermined stroke while ensuring the smoothness of its movement. However, the existing guiding structures mostly only guide the movement of one component and cannot guide multiple components simultaneously, unable to meet the need for guiding combined movements. For example, a movement of a massage shawl disclosed in a prior patent (application number: 202322153641.8) includes a base and a massage component provided on the base. The massage component includes a transmission shaft, a driving motor for driving the transmission shaft to rotate, and a pressing head sleeved on the transmission shaft. The transmission shaft is perpendicular to the output shaft of the driving motor, and the output shaft of the driving motor is linked and cooperated with the transmission shaft through a commutation mechanism. An inclined eccentric wheel synchronously rotating with the transmission shaft is provided on the transmission shaft. An extrusion inclined surface is provided on the inclined eccentric wheel, and an inclined matching surface adapted thereto is provided on one side of the pressing head facing the inclined eccentric wheel. A guiding groove is also provided on the base along the axial direction of the transmission shaft, and a guiding member for guiding and sliding in the guiding groove is provided on the pressing head. A limiting structure for preventing the pressing head from detaching is also provided on the transmission shaft. The guiding seat disclosed in this prior patent is a guiding structure, which guides the guiding member through the guiding groove. However, this guiding seat can only meet the movement mode of the pressing head swinging around the transmission shaft and cannot meet the movement mode of the pressing head performing eccentric movement relative to the transmission shaft during swinging.

[0037] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0038] See also Figure 1 The present embodiment provides a guide limit member, including a sleeve ring 1, a connecting portion 2, a limit seat 3, and a guide rod 4. The two ends of the connecting portion 2 are respectively fixed to the guide rod 4 and the sleeve ring 1. The limit seat 3 is fixedly arranged on the connecting portion 4. A limit groove 31 is arranged on the limit seat 3. The limit groove 31 penetrates through the side of the limit seat 3 facing the sleeve ring 1 to form a first opening 32.

[0039] The guide limit member can be movably mounted on the first external structure through a sleeve ring 1, and the second external structure movable on the first external structure can be movably limited by the limit groove 31 of the limit seat 3 through the first opening 32, and the guide rod 4 is movably connected to the third external structure; that is, the guide limit member can meet the requirements of guiding the eccentric movement and swing of the second external structure on the first external structure through its structural setting.

[0040] In this embodiment, the top of the limiting groove 31 passes through the side of the limiting seat 3 away from the connecting portion 2 to form a second opening 33, and the first opening 32 is connected to the second opening 33. The provision of the second opening 33 can facilitate the assembly of the second external structure and the limiting groove 31. Specifically, in other implementations, either the first opening 32 or the second opening 33 can be provided.

[0041] In this embodiment, an inclined surface 34 is formed at the bottom end of the limiting groove 31 and is inclined toward the guide rod 4. Since the limiting groove 31 is used to guide the swing of the second external structure, and the second external structure is in an inclined state when it moves to the lowest point at the limiting groove 31, the setting of the inclined surface 34 is more suitable for the swing process.

[0042] In this embodiment, a weight-reducing groove 41 is provided on the upper side of the guide rod 4. The setting of the weight-reducing groove 41 can not only reduce the weight of the guide rod 4, but also reduce costs, and can also avoid the phenomenon of shrinkage during the injection molding production of the guide and limit member.

[0043] In this embodiment, the guide rod 4 includes a connecting portion 43 and a guide portion 42 that is integrally semi-cylindrical. Both ends of the connecting portion 43 are respectively fixed to the connecting portion 2 and the guide portion 42. The setting of the semi-cylindrical guide portion 42 can make the movement of the guide rod 4 on the third external structure smoother.

[0044] In this embodiment, avoidance grooves 431 are provided on both the left and right sides of the connecting portion 43, and both of the two avoidance grooves 431 penetrate the lower side of the connecting portion 43. The setting of the two avoidance grooves 431 can enable the guide rod 4 to make an avoidance when moving on the third external structure.

[0045] In this embodiment, the guide and limit member is integrally formed. The integral forming can be injection molding or casting.

[0046] See Figures 1-3 , specifically, in order to make the description of this embodiment clearer, the first external structure can refer to the rotating seat 5 and the eccentric seat 6 in the following linkage mechanism, the second external structure can refer to the swinging member 7 in the following linkage mechanism, and the third external structure can refer to the guide assembly 8 in the following linkage mechanism. However, the following linkage mechanism is only one specific use of the guide and limit member; the guide and limit member can also not be limited to this use, and other specific applications of the guide and limit member can be determined according to the specific use requirements of the user.

[0047] See Figures 1-3 , this embodiment also provides a linkage mechanism, including:

[0048] A guide and limit member, including a socket ring 1, a connecting portion 2, a limit seat 3, and a guide rod 4. Both ends of the connecting portion 2 are respectively fixed to the guide rod 4 and the socket ring 1. The limit seat 3 is fixedly arranged on the connecting portion 4. A limit groove 31 is provided on the limit seat 3, and the limit groove 31 penetrates through one side of the limit seat 3 facing the socket ring 1 to form a first opening 32;

[0049] A rotating seat 5, a driving end 51 connected to an external driving structure is provided at the center of the lower side of the rotating seat 5. The external driving structure can drive the rotating seat 5 to rotate through the driving end 51; specifically, the external driving structure can be an existing driving structure such as a motor; an eccentric seat 6 is eccentrically arranged on the upper side of the rotating seat 5. When the driving end 51 of the external driving structure drives the rotating seat 5 to rotate, the eccentric seat 6 makes an eccentric rotation on the rotating seat 5; the socket ring 1 is movably sleeved on the eccentric seat 6, a swinging inclined surface 61 is provided on the upper side of the eccentric seat 6, and a swinging column 62 is fixedly arranged on the swinging inclined surface 61;

[0050] The swinging member 7 has a limiting projection 71 fixedly arranged on its side and a swinging abutting surface 72 arranged on its lower side. The swinging member 7 is rotatably sleeved on the swinging column 62, and the swinging abutting surface 72 movably abuts against the swinging inclined surface 61. The limiting projection 71 passes through the first opening 32 to be movably arranged in the limiting groove 31;

[0051] A guiding assembly 8 for guiding the movement of the guiding and limiting member is movably connected to the end of the guiding rod 4 away from the connecting portion 2.

[0052] The driving end 51 of the external driving structure drives the rotating seat 5 to rotate. At this time, the eccentric seat 6 rotates eccentrically on the rotating seat 5 and drives the socket ring 1 to move. The end of the guiding rod 4 away from the socket ring 1 makes a reciprocating linear motion on the guiding assembly 8 to ensure that the socket ring 1 and the eccentric seat 6 can rotate relatively; and at this time, while the swinging member 7 rotates eccentrically following the eccentric seat 6, based on the guiding of the limiting projection 71 by the limiting groove 31 and the relative rotation of the socket ring 1 and the eccentric seat 6, the swinging abutting surface 72 of the swinging member 7 and the swinging inclined surface 61 move relatively, and the swinging member 7 swings around the swinging column 62 on the swinging inclined surface 61, thereby realizing that the swinging member 7 swings on the rotating seat 5 while making an eccentric motion.

[0053] In this embodiment, the linkage mechanism further includes an anti - detachment member 9. A socket hole 73 is arranged in the swinging member 7, and a rotating ring 74 is fixed in the socket hole 73. The rotating ring 74 is rotatably sleeved on the swinging column 62. The anti - detachment member 9 extends into the socket hole 73 to be detachably connected to the swinging column 62, and the periphery of the anti - detachment member 9 corresponds to the rotating ring 74. Through the cooperation of the anti - detachment member 9 and the swinging column 62, the swinging member 7 can be made to rotate on the swinging column 62 without detachment.

[0054] In this embodiment, the top end of the limiting groove 31 penetrates through the end of the limiting seat 3 away from the connecting portion 2 to form a second opening 33. The setting of this second opening 33 can facilitate the assembly of the limiting projection 71 on the swinging member 7 and the limiting groove 31.

[0055] In this embodiment, the bottom end of the limiting groove 31 forms an inclined surface 34 inclined towards the guiding rod 4. Based on the fact that the limiting groove 31 is used to guide the swinging of the swinging member 7, and when the swinging member 7 swings, its limiting projection 71 is in an inclined state when it moves to the lowest point at the limiting groove 31, so the setting of this inclined surface 34 is more suitable for the up - and - down movement of the limiting projection 71 during this swinging process.

[0056] In this embodiment, a weight - reducing groove 41 is arranged on the upper side of the guiding rod 4. The setting of the weight - reducing groove 41 can not only reduce the weight of the guiding rod 4, but also reduce the cost, and can also avoid the phenomenon of shrinkage during the injection molding production of this guiding and limiting member.

[0057] In this embodiment, the guide rod 4 includes a connecting portion 43 and a guide portion 42 which is integrally semi-cylindrical. Both ends of the connecting portion 43 are respectively fixed to the connecting portion 2 and the guide portion 42. When the guide portion 42 makes a reciprocating linear motion at the guide assembly 8, it will also rotate forward and backward to a certain extent. Its semi-cylindrical shape can make its reciprocating linear motion at the guide assembly 8 smoother.

[0058] In this embodiment, avoidance grooves 431 are provided on both the left and right sides of the connecting portion 43, and both of the two avoidance grooves 431 penetrate the lower side of the connecting portion 43. Based on the fact that when the guide portion 42 makes a reciprocating linear motion at the guide assembly 8, the connecting portion 43 will deflect to the left and right sides to a certain extent. Therefore, the provision of the avoidance grooves 431 on both its left and right sides can provide avoidance during deflection.

[0059] In this embodiment, the guide assembly 8 includes a sliding groove 81. Guide side walls 82 are provided on both the left and right sides of the sliding groove 81. The guide portion 42 is movably arranged in the sliding groove 81, and the avoidance grooves 431 on both the left and right sides of the connecting portion 43 respectively correspond to the guide side walls 82 on both the left and right sides of the sliding groove 81. When the guide portion 42 makes a reciprocating linear motion at the sliding groove 81, the guide side walls 82 on both the left and right sides of the sliding groove 81 can guide its motion; and the provision of the avoidance grooves 431 on both the left and right sides of the connecting portion 43 can provide avoidance for the guide side walls 82 on both the left and right sides of the sliding groove 81 during this motion process.

[0060] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
