Installation debugging piece of lifting window

Abstract

According to the installation debugging piece of the lifting window, in the operation process, the first limiting part of the pawl enters the limiting clamping groove of the ratchet wheel and is parallel to the inner wall of the limiting clamping groove, and surface contact is formed. When the lifting assembly is driven to move, if the ratchet wheel rotates around the first direction, due to the fact that the first limiting part is in surface contact with the inner wall of the limiting clamping groove, rotation of the ratchet wheel in the first direction is limited, and the ratchet wheel can only rotate in the direction opposite to the first direction and is prevented from rotating in the first direction. The first limiting part is in surface contact with the ratchet, so that the acting force of the pawl on the ratchet wheel is distributed more uniformly, the concentrated pressure on a single acting point is reduced, and the service life of the ratchet wheel and the pawl is prolonged. The first limiting part and the inner wall of the limiting clamping groove are arranged in parallel, surface contact is formed, the contact area is increased, and the meshing stability is improved. The first limiting part is in surface contact with the ratchet, and a dead point position is formed, so that concentrated stress caused by point contact is avoided, and abrasion of the tooth surface of the ratchet wheel is reduced.

Description

Technical Field

[0001] This application relates to the field of electric lifting windows, and in particular to an installation and debugging part for a lifting window. Background Art

[0002] An electric window is composed of a window sash, a window frame, a driving motor, a lifting component (chain or slide rail), etc. The driving motor can drive the lifting component to move, so as to drive the window sash to open and close relative to the window frame.

[0003] In the existing installation process, the driving motor needs to be installed on the profile of the window frame, and a ratchet wrench is required for fixation during the installation process. In the process of using the existing ratchet wrench, since the ratchet and the pawl are in point contact, a dead point position is formed, so that the limiting position of the pawl will abut against the tooth surface of the ratchet, thereby achieving the limiting effect.

[0004] However, in the process of use, the force of the pawl on the ratchet presents a point contact mode, so that the force of the pawl on the ratchet directly acts on the tooth surface of the ratchet, so that the force of the pawl abuts against the side surface of the ratchet tooth in a point contact mode. During long-term use, the pawl will damage the ratchet, so that the ratchet wrench cannot be used. Summary of the Utility Model

[0005] In view of this, it is necessary to provide an installation and debugging part for a lifting window to solve the above problems.

[0015] The pawl is provided with a second limiting portion, and the second limiting portion is symmetrically arranged with the first limiting portion with the first connecting shaft as the axis; the second limiting portion has a fourth limiting surface;

[0016] Wherein, when the second limiting portion meshes with the ratchet wheel, the second limiting portion is received in one of the limiting slots, and the fourth limiting surface is parallel to the third limiting surface to limit the ratchet wheel from rotating around the second direction, and the first direction is opposite to the second direction.

[0017] In at least one embodiment of the present application, when the second limiting portion meshes with the ratchet wheel, the connection line from the first connecting shaft to the third limiting surface is perpendicular to the third limiting surface, so that when the ratchet wheel rotates around the second direction, the fourth limiting surface abuts against the third limiting surface.

[0018] In at least one embodiment of the present application, when the pawl meshes with the ratchet wheel, there is a gap between the ratchet wheel and the pawl, and the width of the gap is denoted as a, satisfying the relationship: 0.05mm ≤ a ≤ 0.2mm.

[0019] In at least one embodiment of the present application, the first limiting portion and the second limiting portion are located on one side of the pawl, and a third limiting portion is provided on the other side of the pawl;

[0020] The main body is provided with a receiving groove and an activity space communicated with the receiving groove, and the ratchet wheel and the pawl are movably received in the activity space;

[0021] The installation and debugging member of the lifting window further includes:

[0022] An elastic component, one end of which is received in the receiving groove, and the other end extends through the receiving groove to the activity space;

[0023] The elastic component abuts against the third limiting portion to fix the pawl.

[0024] In at least one embodiment of the present application, the third limiting portion is provided with a first abutting surface and a second abutting surface connected to the first abutting surface;

[0025] When the elastic component abuts against the first abutting surface, the rotation of the ratchet pawl around the first connection axis in the first direction is restricted;

[0033] When driving the lifting component to move, if the ratchet wheel rotates in the first direction, due to the surface contact formed between the first limiting portion and the inner wall of the limiting card slot, the rotation of the ratchet wheel in the first direction is restricted and it can only rotate in the opposite direction of the first direction, preventing the ratchet wheel from rotating in the first direction.

[0034] Since the first limiting portion and the ratchet teeth are in surface contact, the force exerted by the ratchet pawl on the ratchet wheel is more evenly distributed, reducing the concentrated pressure on a single acting point and extending the service life of the ratchet wheel and the ratchet pawl.

[0035] The first limiting portion is arranged parallel to the inner wall of the limiting card slot to form a surface contact, increasing the contact area and improving the stability of meshing.

[0036] Since the first limiting portion and the ratchet teeth are in surface contact and form a dead point position, the concentrated stress caused by point contact is avoided, the wear of the ratchet tooth surface is reduced, and the service life of the component is extended.

[0051] The embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0052] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "rear", and similar expressions used herein are only for the purpose of illustration.

[0053] An installation and debugging part for a lifting window is provided in an embodiment of the present application, including:

[0054] A ratchet wheel having a plurality of ratchet teeth, and a limiting card slot is formed between two adjacent ratchet teeth;

[0055] A pawl is protrudingly provided with a first limiting portion, and the first limiting portion meshes with the ratchet wheel to limit the ratchet wheel from rotating in a first direction. The first limiting portion is received in one of the limiting card slots and is arranged parallel to the inner wall of the limiting card slot to form a surface contact.

[0056] In this embodiment, during the operation process, the first limiting portion of the pawl enters the limiting card slot of the ratchet wheel, is arranged parallel to the inner wall of the limiting card slot, and forms a surface contact.

[0057] When driving the lifting component to move, if the ratchet wheel rotates in the first direction, since the first limiting portion forms a surface contact with the inner wall of the limiting card slot, the rotation of the ratchet wheel in the first direction is restricted and it can only rotate in the opposite direction of the first direction, preventing the ratchet wheel from rotating in the first direction.

[0058] Since the first limiting portion and the ratchet teeth are in surface contact, the acting force of the pawl on the ratchet wheel is more evenly distributed, reducing the concentrated pressure on a single acting point and extending the service life of the ratchet wheel and the pawl.

[0059] The first limiting portion is arranged parallel to the inner wall of the limiting card slot to form a surface contact, increasing the contact area and improving the stability of meshing.

[0060] Since the first limiting portion and the ratchet teeth are in surface contact and form a dead point position, the concentrated stress caused by point contact is avoided, the wear of the ratchet tooth surface is reduced, and the service life of the component is extended.

[0061] Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0062] An embodiment of the present application provides an installation and debugging part 100 for a lifting window, including:

[0063] A ratchet wheel 110 having a plurality of ratchet teeth 111, and a limit card slot 110a is formed between two adjacent ratchet teeth 111;

[0064] A pawl 120 is provided with a first limiting portion 121 protruding therefrom. The first limiting portion 121 meshes with the ratchet wheel 110 to limit the ratchet wheel 110 from rotating around the first direction A. The first limiting portion 121 is received in one of the limit card slots 110a and is arranged parallel to the inner wall of the limit card slot 110a to form a surface contact.

[0065] Please refer to Figures 1-7 , in this embodiment, during the operation, the first limiting portion 121 of the pawl 120 enters the limit card slot 110a of the ratchet wheel 110 and is arranged parallel to the inner wall of the limit card slot 110a to form a surface contact.

[0066] When driving the lifting assembly to move, if the ratchet wheel 110 rotates around the first direction A, since the first limiting portion 121 forms a surface contact with the inner wall of the limit card slot 110a, the rotation of the ratchet wheel 110 in the first direction A is restricted and it can only rotate in the opposite direction of the first direction A, preventing the ratchet wheel 110 from rotating along the first direction A.

[0067] Since the first limiting portion 121 and the ratchet teeth 111 are in surface contact, the force exerted by the pawl 120 on the ratchet wheel 110 is more evenly distributed, reducing the concentrated pressure on a single acting point and extending the service life of the ratchet wheel 110 and the pawl 120.

[0068] The first limiting portion 121 is arranged parallel to the inner wall of the limit card slot 110a to form a surface contact, increasing the contact area and improving the stability of meshing.

[0069] Since the first limiting portion 121 and the ratchet teeth 111 are in surface contact and form a dead point position, the concentrated stress caused by point contact is avoided, the wear of the tooth surface of the ratchet wheel 110 is reduced, and the service life of the assembly is extended.

[0070] It should be noted that the ratchet teeth 111 are meshing teeth, and the outer shape of the limit card slot 110a is generally a right-angled triangular groove.

[0071] The ratchet wheel 110 has a plurality of ratchet teeth 111, and a limit card slot 110a is formed between two adjacent ratchet teeth 111. The limit and control of the rotation direction are achieved through the cooperation of the ratchet teeth 111 and the pawl 120.

[0072] The pawl 120 is provided with a first limiting portion 121 protruding therefrom. The first limiting portion 121 is a protruding right-angled triangular block.

[0073] The first limiting part 121 engages with the ratchet wheel 110 to limit the rotation of the ratchet wheel 110 in the first direction A. The first limiting part 121 is received in the limit slot 110a and is arranged parallel to the inner wall of the limit slot 110a to form a surface contact.

[0074] The first limiting part 121 can be accurately received in the limit slot 110a to form a surface contact, which increases the contact area between the pawl 120 and the ratchet wheel 110, reduces the wear problem caused by point contact (dead point position), and improves the durability and reliability of the component.

[0075] The first direction A is the clockwise direction.

[0076] In at least one embodiment of the present application, the installation and debugging part 100 of the lifting window further includes:

[0077] A main body 130, the main body 130 is provided with a first connecting shaft 131, the first connecting shaft 131 penetrates through the pawl 120, and the pawl 120 is rotatably connected to the main body 130 through the first connecting shaft 131;

[0078] The limit slot 110a has a first limit surface 110b;

[0079] Wherein, when the first limiting part 121 engages with the ratchet wheel 110, the connection line from the first connecting shaft 131 to the first limit surface 110b is perpendicular to the first limit surface 110b, so that when the ratchet wheel 110 rotates in the first direction A, the first limiting part 121 abuts against the first limit surface 110b.

[0080] Please refer to Figures 1-8 , in this embodiment, the pawl 120 is installed on the main body 130, the first connecting shaft 131 is installed on the main body 130 and penetrates through the pawl 120, so that the pawl 120 can rotate freely relative to the main body 130.

[0081] When operating the installation and debugging part 100 of the lifting window, the first limiting part 121 of the pawl 120 enters the limit slot 110a of the ratchet wheel 110. The pawl 120 is rotatably connected to the main body 130 through the first connecting shaft 131, so that it can rotate freely relative to the wrench within a certain range (rotate in the second direction B).

[0082] When the ratchet wheel 110 rotates in the first direction A, due to the limitation of the first limiting part 121, the first limiting part 121 forms a surface contact with the first limit surface 110b in the limit slot 110a, and the ratchet wheel 110 cannot rotate in the first direction A.

[0083] The surface contact between the ratchet wheel 110 and the pawl 120 reduces local wear, extends the service life of the installation and debugging component 100 of the lifting window, and makes the installation and debugging component 100 of the lifting window more stable during use.

[0084] Through the first connecting shaft 131, the pawl 120 can rotate slightly around the first connecting shaft 131 to ensure accurate meshing with the ratchet wheel 110 during use.

[0085] Surface contact is more durable than point contact, reducing local wear and improving the durability of components.

[0086] The first limiting portion 121 and the first limiting surface 110b ensure that the ratchet wheel 110 can only rotate in the second direction B, preventing the reverse rotation problem caused by misoperation.

[0087] The first limiting surface 110b is a plane; the first connecting shaft 131 is a cylindrical rod; the main body 130 is the main body 130 (strip-shaped plate) of a wrench.

[0088] In at least one embodiment of the present application, the first limiting portion 121 has a second limiting surface 121a. When the first limiting portion 121 is received in the limiting card slot, the first limiting surface 110b is parallel to the second limiting surface 121a.

[0089] Please refer to Figures 1-8 , in this embodiment, during the installation and debugging process, the pawl 120 on the main body 130 is in the initial position, and the first limiting portion 121 has not yet meshed with the ratchet wheel 110.

[0090] When the main body 130 operates the ratchet wheel 110, the pawl 120 is rotated so that the first limiting portion 121 enters the limiting card slot 110a. At this time, the first limiting surface 110b and the second limiting surface 121a are arranged in parallel, forming a surface contact with the limiting surface in the limiting card slot 110a.

[0091] Since the first limiting surface 110b and the second limiting surface 121a are arranged in parallel, when the ratchet wheel 110 rotates around the first direction A, the first limiting portion 121 forms a surface contact with the inner wall of the limiting card slot 110a, and a dead point position is formed between the first limiting surface 110b and the second limiting surface 121a, preventing the ratchet wheel 110 from rotating around the first direction A and ensuring that the ratchet wheel 110 can only rotate in the second direction B.

[0092] During long-term use, due to the surface contact between the first limiting surface 110b and the second limiting surface 121a, the stress distribution between the pawl 120 and the ratchet wheel 110 is uniform, reducing wear and improving the durability and stability of the installation and debugging component 100 of the lifting window.

[0093] Through the design of surface contact, it is ensured that the ratchet wheel 110 can only rotate in the second direction B, preventing the reverse rotation problem caused by misoperation and improving the reliability of the entire installation and debugging component.

[0094] In at least one embodiment of the present application, a third limiting surface 110c connected to the first limiting surface 110b is provided in the limiting card slot 110a, and the third limiting surface 110c is perpendicular to the first limiting surface 110b;

[0095] The pawl 120 is provided with a second limiting portion 122, and the second limiting portion 122 is symmetrically arranged with the first limiting portion 121 with the first connecting shaft 131 as the axis; the second limiting portion 122 has a fourth limiting surface 122a;

[0096] Wherein, when the second limiting portion 122 meshes with the ratchet wheel 110, the second limiting portion 122 is received in one of the limiting card slots 110a, and the fourth limiting surface 122a is parallel to the third limiting surface 110c to limit the ratchet wheel 110 from rotating around the second direction B, and the first direction A is opposite to the second direction B.

[0097] Please refer to Figures 1-8 , in this embodiment, when the main body 130 (wrench) operates the ratchet wheel 110, by rotating the pawl 120, the first limiting portion 121 enters the limiting card slot 110a. At this time, the first limiting surface 110b and the second limiting surface 121a are arranged in parallel, forming a surface contact with the limiting surface in the limiting card slot 110a, restricting the ratchet wheel 110 from rotating around the first direction A, so that the ratchet wheel 110 can only rotate along the second direction B.

[0098] When the main body 130 (wrench) operates the ratchet wheel 110, by rotating the pawl 120, the second limiting portion 122 enters the limiting card slot 110a, and the fourth limiting surface 122a is parallel to the third limiting surface 110c, forming a surface contact with the limiting surface in the limiting card slot 110a, restricting the ratchet wheel 110 from rotating around the second direction B, so that the ratchet wheel 110 can only rotate along the first direction A.

[0099] When the ratchet wheel 110 rotates around the first direction A, the first limiting portion 121 forms a surface contact with the inner wall of the limiting card slot 110a, preventing the ratchet wheel 110 from rotating around the first direction A.

[0100] When the ratchet wheel 110 rotates around the second direction B, the second limiting portion 122 forms a surface contact with the inner wall of the limiting card slot 110a, preventing the ratchet wheel 110 from rotating around the second direction B.

[0101] The third limiting surface 110c is perpendicular to the first limiting surface 110b, increasing the contact area during meshing and enhancing the stability of the meshing between the pawl 120 and the ratchet wheel 110.

[0102] The second limiting portion 122 and the fourth limiting surface 122a ensure that the rotation of the ratchet 110 can be effectively restricted in both directions, improving the reliability of the installation and debugging component 100 of the entire lifting window. According to different requirements, the ratchet 110 rotates in the first direction A or the second direction B to provide two-way restriction.

[0103] The surface contact reduces the local wear between the pawl 120 and the ratchet 110, extending the service life of the installation and debugging component 100 of the lifting window.

[0104] The surface contact ensures the stable rotation of the ratchet 110 in a predetermined direction, preventing the reverse rotation problem caused by misoperation and ensuring the accuracy and reliability of the operation.

[0105] The fourth limiting surface 122a is arranged in parallel with the third limiting surface 110c, and the first limiting surface 110b is arranged in parallel with the second limiting surface 121a. The surface contact effectively disperses the stress, reduces the single-point wear, and improves the overall durability of the installation and debugging component 100 of the lifting window, making it suitable for long-term and high-frequency use.

[0106] The third limiting surface 110c that is connected to the first limiting surface 110b is provided in the limiting card slot 110a, and the third limiting surface 110c is arranged perpendicular to the first limiting surface 110b.

[0107] The third limiting surface 110c provides an additional contact surface, which is arranged perpendicular to the first limiting surface 110b, increasing the contact area and stability when the pawl 120 meshes with the ratchet 110.

[0108] The second limiting portion 122 is provided on the pawl 120, and the second limiting portion 122 is symmetrically arranged with the first limiting portion 121 about the first connecting shaft 131.

[0109] The second limiting portion 122 is symmetrically arranged with the first limiting portion 121 to ensure that the pawl 120 can effectively restrict the movement of the ratchet 110 in both rotational directions. And the second limiting portion 122 has the same shape as the first limiting portion 121.

[0110] The second limiting portion 122 has a fourth limiting surface 122a, and the fourth limiting surface 122a is a surface of the second limiting portion 122. When the second limiting portion 122 is received in the limiting card slot 110a, the fourth limiting surface 122a is parallel to the third limiting surface 110c, so that the fourth limiting surface 122a and the third limiting surface 110c are in surface contact to restrict the rotation of the ratchet 110 around the second direction B.

[0111] In at least one embodiment of the present application, when the second limiting portion 122 meshes with the ratchet wheel 110, the line connecting the first connecting shaft 131 to the third limiting surface 110c is perpendicular to the third limiting surface 110c, so that when the ratchet wheel 110 rotates around the second direction B, the fourth limiting surface 122a abuts against the third limiting surface 110c.

[0112] In this embodiment, during the installation and debugging process, the pawl 120 on the main body 130 is in the initial position, and the second limiting portion 122 has not yet meshed with the ratchet wheel 110.

[0113] When the main body 130 operates the ratchet wheel 110, the pawl 120 is rotated to make the second limiting portion 122 enter the limiting card slot 110a. At this time, the line connecting the first connecting shaft 131 to the third limiting surface 110c is perpendicular to the third limiting surface 110c.

[0114] Due to the perpendicular relationship, the second limiting portion 122 and the third limiting surface 110c form a surface contact, ensuring the stability of the meshing.

[0115] When the ratchet wheel 110 rotates around the second direction B, the second limiting portion 122 and the third limiting surface 110c form a surface contact, effectively restricting the rotation of the ratchet wheel 110 around the second direction B and preventing reverse rotation.

[0116] During continuous use, the surface contact between the second limiting portion 122 and the third limiting surface 110c makes the stress distribution between the pawl 120 and the ratchet wheel 110 uniform, reducing wear and improving the durability and stability of the installation and debugging part 100 of the lifting window.

[0117] The contact area is increased, the stability of the meshing is enhanced, and the problem of unstable meshing that may be caused by single-point contact is avoided.

[0118] The first limiting portion 121 and the second limiting surface 121a, the fourth limiting surface 122a and the third limiting surface 110c ensure that the rotation of the ratchet wheel 110 in two directions can be effectively restricted, improving the reliability of the entire installation and debugging part 100 of the lifting window.

[0119] The surface contact design makes the stress distribution more uniform, reduces wear, and improves the durability and service life of the components.

[0120] The surface contact design effectively disperses the stress, reduces single-point wear, improves the overall durability of the entire installation and debugging part 100 of the lifting window, and is suitable for long-term and high-frequency use.

[0121] In at least one embodiment of the present application, when the pawl 120 meshes with the ratchet wheel 110, there is a gap between the ratchet wheel 110 and the pawl 120. The width of the gap is denoted as a and satisfies the relationship: 0.05 mm ≤ a ≤ 0.2 mm.

[0122] Please refer to Figures 1-8 , in this embodiment, when the main body 130 (wrench) operates the ratchet wheel 110, the rotary pawl 120 is rotated to mesh with the ratchet wheel 110. During this process, the gap a keeps an appropriate distance between the pawl 120 and the ratchet wheel 110.

[0123] When the pawl 120 meshes with the ratchet wheel 110, the existence of the gap a ensures that there is no too tight or too loose contact between them, thus ensuring the flexibility and stability of the meshing.

[0124] Through the meshing of the pawl 120 and the ratchet wheel 110, the pawl 120 can effectively limit the rotation direction of the ratchet wheel 110. At the same time, the gap a ensures that during the rotation process, the friction and wear between the pawl 120 and the ratchet wheel 110 are minimized.

[0125] When restricting the movement in the first direction A or the second direction B, the appropriate gap enables the pawl 120 and the ratchet wheel 110 to mesh flexibly, without causing difficult operation due to being too tight or unstable meshing due to being too loose, thereby improving the overall stability of the installation and debugging part 100 of the lifting window.

[0126] The existence of the gap a makes the operation process more flexible and stable, avoiding the operation resistance caused by excessive friction and improving the user experience.

[0127] By controlling the width of the gap between 0.05 mm and 0.2 mm, it is ensured that the pawl 120 and the ratchet wheel 110 can work properly under various operating conditions, preventing functional failures caused by being too tight or too loose.

[0128] In at least one embodiment of the present application, the first limiting part 121 and the second limiting part 122 are located on one side of the pawl 120, and a third limiting part 123 is provided on the other side of the pawl 120;

[0129] The main body 130 is provided with a receiving groove 130a and an activity space 130b communicating with the receiving groove 130a. The ratchet wheel 110 and the pawl 120 are movably received in the activity space 130b;

[0130] The installation and debugging part 100 of the lifting window further includes:

[0131] An elastic component 140, one end of which is received in the receiving groove 130a and the other end passes through the receiving groove 130a and extends into the activity space 130b;

[0132] The elastic component 140 abuts against the third limiting portion 123 to fix the pawl 120.

[0133] Please refer to Figures 1-8 , in this embodiment, when the main body 130 operates the ratchet wheel 110, the first limiting portion 121 or the second limiting portion 122 of the pawl 120 engages with the limiting slot 110a of the ratchet wheel 110 to limit the rotation of the ratchet wheel 110 in a predetermined direction.

[0134] The movement space 130b provides a movement space 130b for the pawl 120 and the ratchet wheel 110, ensuring that they can move freely during operation.

[0135] One end of the elastic component 140 is fixed in the receiving groove 130a, and the other end contacts the third limiting portion 123, providing an elastic force to fix the pawl 120 and enabling it to automatically reset after operation.

[0136] Through the engagement of the first limiting portion 121 or the second limiting portion 122 of the pawl 120, the rotation of the ratchet wheel 110 in two different directions is respectively restricted, ensuring that it can only move in a predetermined direction.

[0137] The elastic force provided by the elastic component 140 enables the pawl 120 to automatically reset during operation, ensuring that it can return to the restricted position after each operation to prevent the disengagement between the pawl 120 and the ratchet wheel 110 during use, simplifying the operation steps and improving the efficiency.

[0138] In at least one embodiment of the present application, the third limiting portion 123 is provided with a first abutting surface 123a and a second abutting surface 123b connected to the first abutting surface 123a;

[0139] Wherein, when the elastic component 140 abuts against the first abutting surface 123a, it restricts the rotation of the pawl 120 around the first connecting shaft 131 in the first direction A;

[0140] When the elastic component 140 abuts against the second abutting surface 123b, it restricts the rotation of the pawl 120 around the first connecting shaft 131 in the second direction B.

[0141] Please refer to Figures 1-8 , in this embodiment, when the main body 130 (wrench) operates the ratchet wheel 110, the first limiting portion 121 or the second limiting portion 122 of the pawl 120 respectively engages with the limiting slot 110a of the ratchet wheel 110.

[0142] When the pawl 120 attempts to rotate about the first connecting shaft 131 in the second direction B, the elastic component 140 contacts the first abutting surface 123a of the third limiting portion 123, restricting the rotation of the pawl 120 in the first direction A.

[0143] When the pawl 120 attempts to rotate about the first connecting shaft 131 in the first direction A, the elastic component 140 contacts the second abutting surface 123b of the third limiting portion 123, restricting the rotation of the pawl 120 in the second direction B.

[0144] The elastic component 140 provides an elastic force during the abutting process, enabling the pawl 120 to automatically reset after operation and remain in the restricted position.

[0145] Through the first abutting surface 123a and the second abutting surface 123b of the third limiting portion 123, the rotation of the pawl 120 in two different directions is respectively restricted, ensuring that the ratchet wheel 110 can only rotate in a predetermined direction.

[0146] Through the interaction between the first abutting surface 123a and the second abutting surface 123b of the third limiting portion 123 and the elastic component 140, the rotation of the pawl 120 in both directions can be effectively restricted, improving the reliability of the installation and debugging component 100 of the lifting window.

[0147] Ensure that the pawl 120 can be stably fixed during rotation, reduce the friction and wear caused by direct contact, and extend the service life of the components.

[0148] It should be noted that the first abutting surface 123a is located on the side close to the second limiting portion 122, and the second abutting surface 123b is located on the side close to the first limiting portion 121.

[0149] In at least one embodiment of the present application, the elastic component 140 includes:

[0150] A limiting ball 141, one side of which is received in the receiving groove, and the other side extends into the moving space 130b and abuts against the pawl 120;

[0151] A spring, one end of which is fixed in the receiving groove, and the other end abuts against the limiting ball 141.

[0152] Please refer to Figures 1-8 , in this embodiment, when the main body 130 (wrench) operates the ratchet wheel 110, the first limiting portion 121 or the second limiting portion 122 of the pawl 120 respectively engages with the limiting card slot 110a of the ratchet wheel 110, restricting the rotation of the ratchet wheel 110 in a predetermined direction.

[0153] Since the limiting ball 141 contacts the third limiting portion 123 of the pawl 120, the elastic force provided by the spring fixes the pawl 120 in place.

[0154] When the operating force is withdrawn, the elastic force of the spring 142 pushes the limiting ball 141 back to its original position, thereby pushing the pawl 120 back to its initial position to achieve automatic reset.

[0155] The elastic component 140 provides a continuous elastic force throughout the process, ensuring that the pawl 120 can be stably reset after operation and maintaining its meshing state with the ratchet 110.

[0156] By the meshing of the first limiting portion 121 and the second limiting portion 122 of the pawl 120, the rotation of the ratchet 110 in two different directions is respectively restricted, ensuring that it can only move in a predetermined direction.

[0157] When the main body 130 (wrench) operates the ratchet 110, the first limiting portion 121 or the second limiting portion 122 of the pawl 120 meshes with the limiting slot 110a of the ratchet 110 respectively, restricting the rotation of the ratchet 110 in a predetermined direction.

[0158] Since the limiting ball 141 contacts the first abutting surface 123a or the second abutting surface 123b of the pawl 120, a dead point position is formed, preventing the pawl 120 from rotating around the first connecting shaft 131 in the corresponding direction.

[0159] When the limiting ball 141 abuts against the first abutting surface 123a, the rotation of the ratchet 110 along the first direction A is restricted; when the limiting ball 141 abuts against the second abutting surface 123b, the rotation of the ratchet 110 along the second direction B is restricted.

[0160] The elastic force provided by the spring 142 pushes the limiting ball 141 back to its original position, thereby pushing the pawl 120 back to its initial position to achieve automatic reset.

[0161] The elastic component 140 provides a continuous elastic force throughout the process, ensuring that the pawl 120 can be stably reset after operation and maintaining its meshing state with the ratchet 110.

[0162] By the meshing of the first limiting portion 121 and the second limiting portion 122 of the pawl 120, the rotation of the ratchet 110 in two different directions is respectively restricted, ensuring that it can only move in a predetermined direction.

[0163] The dead point position formed by the contact between the limiting ball 141 and the first abutting surface 123a or the second abutting surface 123b ensures that the pawl 120 can maintain a stable fixed state during operation, preventing displacement caused by changes in the operating force.

[0164] The limiting ball 141 moves freely within the receiving groove, providing stable positioning through its contact with the pawl 120, reducing wear caused by direct friction, and extending the service life of the components.

[0165] It should be noted that the limiting ball 141 is spherical, and the spring 142 is a compression spring 142. 142

[0166] In at least one embodiment of the present application, the ratchet 110 includes a rotating portion 112, a gear portion 113, and a connecting portion 114. The rotating portion 112 is rotatably connected to the main body 130, the gear portion 113 meshes with the pawl 120, and the connecting portion 114 passes through the main body 130 and is connected to the outside for installation or disassembly.

[0167] Please refer to Figures 1-8 , in this embodiment, the rotating portion 112 of the ratchet 110 is rotatably connected to the main body 130, enabling the ratchet 110 to freely rotate around its axis.

[0168] The connecting portion 114 passes through the main body 130 and is connected to an external fastener (the hexagonal groove on the hexagonal bolt), ensuring that the ratchet 110 is fixed in the appropriate position and ready for operation.

[0169] The first limiting portion 121 or the second limiting portion 122 of the pawl 120 meshes with the gear portion 113 of the ratchet 110, and the rotation direction of the ratchet 110 is controlled through the ratchet teeth 111 of the gear portion 113.

[0170] During the operation process, the rotating portion 112 of the ratchet 110 allows the ratchet 110 to freely rotate, and the meshing of the gear portion 113 with the pawl 120 ensures that the ratchet 110 can only rotate in a predetermined direction.

[0171] During actual use, the ratchet 110 is operated through the main body 130 (wrench). The rotating portion 112 provides flexible rotation, the meshing of the gear portion 113 with the pawl 120 controls the rotation direction, and the connecting portion 114 ensures a firm connection.

[0172] The elastic component 140, through the action of the limiting ball 141 and the spring 142, ensures the stability and reset ability of the pawl 120 during the operation process.

[0173] The connecting portion 114 passes through the main body 130 and is connected to an external fastener (the hexagonal groove on the hexagonal bolt), ensuring the firm installation or convenient disassembly of the ratchet 110.

[0174] The rotational connection between the rotating portion 112 and the main body 130 enables the ratchet 110 to freely rotate around its axis, improving the flexibility and convenience during the operation process.

[0175] The meshing of the gear portion 113 and the pawl 120 ensures the rotation of the ratchet wheel 110 in a predetermined direction through the ratchet teeth 111, providing precise control over the installation operation.

[0176] The connecting portion 114 penetrates through the main body 130 and is connected to an external fastener (the hexagonal groove on the hexagonal bolt), providing a stable installation method and also facilitating disassembly when needed, enhancing the maintainability and operational convenience of the device.

[0177] It should be noted that the connecting portion 114 is an external hexagonal prism (external hexagonal wrench); the rotating portion 112 is cylindrical; and the gear portion 113 is provided with a plurality of ratchet teeth 111 at equal angles on the outer ring.

[0178] The above are only the implementation manners of the present application. It should be pointed out here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present application, but these all fall within the protection scope of the present application.
