[0034] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0035] This embodiment provides a movable buckle, such as Figures 1 to 11 As shown, it includes a buckle 1 and a clamping arm module 2 connected to each other, the clamping arm module 2 may include a housing 201, a transmission assembly, a first clamping arm 202 and a second clamping arm 203, the first clamping arm 202 includes a first hook and a first plate 2021, the second clamping arm 203 includes a second hook and a second plate 2031, and the first plate 2021 and the second plate 2031 are respectively provided with gear grooves 204 along their extension directions. The transmission assembly includes a gear module 205 that is arranged in the housing 201 and can rotate, and a locking module 206 that locks the gear module 205. The first plate 2021 and the second plate 2031 extend into the shell 201 and are located on both sides of the gear module 205. The gear groove 204 is meshed and connected with the gear module 205. The first hook and the second hook are located outside the shell 201 and are arranged opposite to each other. They are relatively close to or far away from each other under the action of the gear module 205, and can be locked by the locking module 206 to limit the relative distance between the first hook and the second hook.

[0036] In this embodiment, the buckle 1 is used to connect with the sheet metal hole of the vehicle, and the buckle 1 and the shell 201 can be firmly connected by welding or detachable means to form an integral structure. The shell 201 provides protection and support for the clamping arm and the transmission assembly, and can be made of high-strength materials to ensure stability and durability during use. The first plate 2021 and the second plate 2031 are arranged horizontally with each other to ensure that the gear module 205 is more stably engaged with the gear groove 204 when rotating. At the same time, the horizontally arranged plate makes it more intuitive and convenient for the staff to adjust the distance of the clamping arm; and because the plate is horizontal, the staff can more easily observe the meshing of the gear module 205 and the gear groove 204, so as to more accurately adjust the distance of the clamping arm.

[0037] The gear module 205 is located between the first plate 2021 and the second plate 2031. When the gear module 205 rotates, the first plate 2021 and the second plate 2031 will move accordingly due to the meshing action of the gear groove 204, so that the movable buckle can clamp objects of different sizes. The locking module 206 and the gear module 205 are located on the same horizontal plane and are arranged on one side of the gear module 205, and are used to lock the gear module 205. When the position of the clamp arm needs to be fixed, the locking module 206 will lock the gear module 205 to prevent it from rotating, thereby maintaining the relative position of the first hook and the second hook unchanged, ensuring the stability of the clamp arm when clamping an object and preventing it from loosening due to external force.

[0038] In actual use, when it is necessary to clamp the PCB board or the wire trough, by rotating the gear module 205, the first clamp arm 202 and the second clamp arm 203 will be relatively close to each other under the action of the gear module 205, so that the PCB board or the wire trough is clamped by the first hook and the second hook. When the PCB board or the wire trough is clamped, the locking module 206 can lock the gear module 205 to prevent it from continuing to rotate, thereby ensuring the stability of the clamping. When it is necessary to release the object, it is only necessary to unlock the locking module 206, and then rotate the gear module 205 in the opposite direction, and the first clamp arm 202 and the second clamp arm 203 will be relatively far away from each other under the action of the gear module 205, so as to release the clamped PCB board or wire trough.

[0039] Through the above technical solution, the relative movement of the first clamping arm 202 and the second clamping arm 203 can be controlled by the gear module 205 and the locking module 206 arranged in the shell 201, and it is ensured that the gear module 205 is firmly locked when needed, so as to keep the relative distance between the first hook and the second hook unchanged; the setting of the gear module 205 allows the first hook and the second hook to be adjusted according to actual needs to adapt to objects of different shapes and sizes, so as to achieve the clamping or release of the wire trough or PCB board, thereby solving the problem that when the buckle 1 is matched with the wire trough or PCB board, there are many types of buckle 1 used, which increases the development cost and the management cost.

[0040] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 The first inserting cavity 2011 and the second inserting cavity 2012 are respectively arranged on opposite sides of the housing 201, and the first plate 2021 and the second plate 2031 are respectively inserted into the housing 201 from the first inserting cavity 2011 and the second inserting cavity 2012, and the first plate 2021 and the second plate 2031 are meshed and connected with the gear module 205 when they are at the farthest ends along the insertion direction. The arrangement of the first inserting cavity 2011 and the second inserting cavity 2012 not only provides a stable insertion space for the clamp arm, but also ensures the accuracy of the clamp arm during movement.

[0041] In order to enhance the stability and clamping force of the clamp arm, in some embodiments, reference Figure 3 , Figure 6 , Figure 7 , Fig.10 and Fig.11 The first hook may include a first vertical section 2022 vertically connected to the end of the first flat plate 2021, and a first flange 2023 vertically connected to the free end of the first vertical section 2022. The second hook may include a second vertical section 2032 vertically connected to the end of the second flat plate 2031, and a second flange 2033 vertically connected to the free end of the second vertical section 2032. Relative to the plane of the shell 201, the first flange 2023 and the second flange 2033 are located on the same horizontal plane and are arranged opposite to each other. The first hook and the second hook are vertically connected to the end of the flat plate through their respective vertical sections, which ensures a firm connection between the hook and the flat plate, thereby improving the stability of the overall structure. The first flange 2023 and the second flange 2033 are located on the same horizontal plane and are arranged opposite to each other, which allows the two hooks to be easily aligned when they are engaged, so as to facilitate the clamping operation to be completed quickly and accurately. When the two hooks are engaged, the interaction between the first flange 2023 and the second flange 2033 will generate a certain pressure, thereby enhancing the fixing effect of the connection point. Once the two hooks are engaged with the PCB board or cable duct, the interaction force between the two hooks will form a locking mechanism to prevent falling off, helping to ensure the stability of the clamping.

[0042] In some embodiments, reference Figure 4 , Figure 6 and Figure 7 The first plate 2021 and the second plate 2031 are provided with stop blocks 207 protruding from the two sides at one end away from the first hook and the second hook, and the inner walls of the first plug-in cavity 2011 and the second plug-in cavity 2012 are provided with stop bars 208, which stop the stop blocks 207 to limit the first clamp arm 202 and the second clamp arm 203 from being separated from the housing 201. The cooperation between the stop bars 208 and the stop blocks 207 effectively limits the movement range of the clamp arm in the housing 201, prevents the clamp arm from accidentally being separated or excessively moved, and improves the stability and safety of the device.

[0043] In some embodiments, reference 3 and Figure 8 The gear module 205 may include a gear shaft 2051, a transmission gear 2052 disposed in the middle of the gear shaft 2051 and located in the housing 201, and a first rotating handle 2053 disposed at one or both ends of the gear shaft 2051 and located outside the housing 201. The gear shaft 2051 passes through the housing 201 and is rotatably connected, and the transmission gear 2052 is meshed and connected with the gear slot 204. For easy operation, the first rotating handles 2053 are respectively disposed at both ends of the gear shaft 2051. The operator only needs to gently rotate the first rotating handles 2053 to easily control the opening and closing of the clamp arm. Through the mutual cooperation between the gear shaft 2051, the transmission gear 2052 and the first rotating handle 2053, efficient and stable power transmission and speed adjustment are achieved. Since the transmission gear 2052 is meshed and connected with the gear slot 204, the movement of the clamp arm can be accurately controlled, and the reliability of the device is further improved.

[0044] In some embodiments, reference Figure 3 and Fig. 9 The locking module 206 includes a locking shaft 2061, a radially protruding locking wedge 2062 disposed in the middle of the locking shaft 2061 and located in the housing 201, and a second rotating handle 2063 disposed at one or both ends of the locking shaft 2061 and located outside the housing 201. The locking shaft 2061 passes through the housing 201 and is rotatably connected, and the locking wedge 2062 can rotate and engage with the teeth of the transmission gear 2052. For easy operation, the second rotating handles 2063 are respectively disposed at both ends of the locking shaft 2061. When the clamp arm needs to be locked, it is only necessary to rotate the second rotating handle 2063 to lock the shaft 2061 so that the locking wedge 2062 engages with the teeth of the transmission gear 2052. The engagement between the locking wedge 2062 and the teeth can ensure that the transmission gear 2052 is firmly fixed in the locked state to prevent it from moving accidentally.

[0045] In some embodiments, reference Figure 3 , Figure 4 , Figure 5 and Fig. 9 , a relative locking slideway 2013 is provided on the housing 201, and the locking shaft 2061 is located in the locking slideway 2013 and can slide to the two ends of the locking slideway 2013, corresponding to the locking wedge 2062 and the teeth of the transmission gear 2052 are engaged or disengaged. By sliding the locking shaft 2061, the locking wedge 2062 can be easily engaged or disengaged with the teeth of the transmission gear 2052, and the operation is simple and convenient. When the locking wedge 2062 is engaged with the teeth, the movement of the transmission gear 2052 can be effectively prevented, thereby preventing the accidental start or movement of the system or equipment. Since the locking shaft 2061 can slide to both ends in the locking slideway 2013, the degree of engagement between the locking wedge 2062 and the teeth can be accurately controlled, which helps to ensure the reliability and stability of the locking mechanism.

[0046] In some embodiments, reference Figure 3 , Figure 4 , Figure 5 and Fig. 9 , a positioning slideway 2014 connected to the locking slideway 2013 at an angle is provided on one side of the locking slideway 2013 close to the gear module 205, and the locking shaft 2061 moves from the locking slideway 2013 into the positioning slideway 2014 and is locked, and at this time, the locking wedge 2062 is engaged with the teeth of the transmission gear 2052. Specifically, the positioning slideway 2014 can be vertically arranged, and the locking slideway 2013 can be arranged so that one end is connected to the top of the positioning slideway 2014 and the other end is inclined downward. When the transmission gear 2052 needs to be locked, the locking shaft 2061 first slides in the locking slideway 2013 until it reaches a position connected to the positioning slideway 2014. Subsequently, the locking shaft 2061 enters the positioning slideway 2014 from the locking slideway 2013 and is locked therein. When the locking shaft 2061 is locked in the positioning slideway 2014, the locking wedge 2062 connected thereto will be connected with the teeth of the transmission gear 2052 to achieve the locking purpose. When unlocking, it is only necessary to slide the locking shaft 2061 to slide it out of the positioning slideway 2014 and into the locking slideway 2013. Since the locking slideway 2013 is set to be tilted downward, there is no need to worry that the locking shaft 2061 will slide into the positioning slideway 2014 again, thereby affecting the use of the device. The design of the positioning slideway 2014 increases the stability of the locking shaft 2061 and reduces the possibility of accidental unlocking due to vibration or other external factors. Moreover, such a setting is simple to operate. The locking and unlocking process can be completed by sliding the locking shaft 2061 without complicated tools or steps, which effectively improves work efficiency.

[0047] It should be understood that by adjusting the angle between the locking slide 2013 and the positioning slide 2014 and the shape and size of the locking wedge 2062, it is possible to adapt to transmission gears 2052 of different sizes and types, thereby improving the flexibility of design.

[0048] In some embodiments, reference Figure 1 , Figure 2 and Figure 4 At least one observation window 3 is provided on the housing 201, and the meshing state of the transmission gear 2052 and the gear slot 204, and the engaging state of the locking wedge 2062 and the transmission gear 2052 can be revealed from the observation window 3. In this way, the operator can check the meshing state of the transmission gear 2052 and the gear slot 204, and the engaging state of the locking wedge 2062 and the transmission gear 2052 at any time through the observation window 3, thereby ensuring the normal operation of the movable buckle.

[0049] In order to provide better connection effect and stability, in some embodiments, such as Figure 1 As shown, the first hook and the second hook are respectively located on opposite sides of the housing 201 with the buckle 1. In this way, interference between the hook and the buckle 1 in the same direction is avoided, which affects their use.

[0050] In some embodiments, Figure 2 As shown, a plurality of reinforcing ribs 4 are arranged at intervals in the housing 201 perpendicular to the moving direction of the first clamp arm 202 and the second clamp arm 203. The reinforcing ribs 4, as the internal supporting structure of the housing 201, can significantly improve the overall strength and rigidity of the housing 201, significantly reduce the deformation and distortion of the housing 201 when subjected to external forces, and further enhance the strength and stability of the housing 201. At the same time, by arranging the reinforcing ribs 4 in the housing 201 perpendicular to the moving direction of the clamp arms, the force on the housing 201 can be evenly distributed to the entire structure instead of being concentrated in a certain local area, which helps to reduce stress concentration and improve the durability and reliability of the housing 201.

[0051] Although the preferred embodiments of the present disclosure have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present disclosure.

[0052] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if these modifications and variations of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is also intended to include these modifications and variations.
