In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0039] In some cases, it is necessary to fix the power cord to prevent the power cord from being damaged or falling off the electrical equipment due to movement or pulling.

[0040] In the related art, a wire clamp is generally used to clamp and fix a power cord. The wire clamp has two clamping pieces, and the power cord is located between the two clamping pieces. Each end of each clamping piece has a threaded hole. Two fasteners respectively pass through the threaded holes at both ends of the clamping piece to connect the two clamping pieces and make the two clamping pieces approach each other to clamp the power cord located in the middle of the clamping pieces. At the same time, the fasteners passing through the clamping pieces can be threadedly connected to the electrical equipment to fix the wire clamp on the electrical equipment, thereby fixing the power cord. It should be noted that the fixing effect of the wire clamp in the related art on the power cord is weak, resulting in the power cord being prone to sliding relative to the two clamping pieces when being pulled, leading to damage to the power cord or detachment from the electrical equipment.

[0041] In order to improve the fixing effect on the power cord, the present utility model provides a fixing clamp to improve the fixing effect on the power cord.

[0042] Referring to Figure 1 and Figure 3 , Figure 1 is a perspective view of the fixing clamp according to the first aspect embodiment of the present application, Figure 3 is Figure 1 a side view of the fixing clamp in

[0043] . According to the fixing clamp of the first aspect embodiment of the present utility model, it includes: a main body 100 and a convex portion 200. Among them, the main body 100 is provided with a through hole 111, and the through hole 111 penetrates through both ends of the main body 100 to facilitate the power cord to pass through the main body 100. In order to improve the fixing effect on the power cord, a convex portion 200 is provided on the inner wall of the through hole 111, and the convex portion 200 can abut against the part of the power cord located inside the through hole 111. It should be understood that the outer side of the power cord is an insulating layer with a certain softness. Thus, when the convex portion 200 abuts against the outer side of the power cord, it can make the outer side of the power cord concave inward to form a concave portion on the outer side of the power cord. When the power cord is subjected to a tensile force, the convex portion 200 on the inner wall of the through hole 111 and the concave portion on the outer side of the power cord are engaged to limit the movement of the power cord and prevent the power cord from sliding relative to the fixing clamp, so as to improve the fixing effect of the fixing clamp on the power cord. Figure 4 and Figure 5 , Figure 4 is a sectional view along the Figure 3 A-A line in Figure 5 is Figure 4An enlarged view of portion B in the figure. A guiding surface 210 is formed on the convex portion 200. The guiding surface 210 is inclined relative to the axis line of the through hole 111. Specifically, the guiding surface 210 is inclined along the first direction and towards the direction close to the axis line. Thus, during the process of the power cord passing through the through hole 111, the outer side of the power cord can be in sliding fit with the guiding surface 210, facilitating the power cord to pass through the position in the through hole 111 corresponding to the convex portion 200, guiding the power cord into the through hole 111 and passing through the through hole 111, playing a guiding role for the power cord, and thus avoiding the convex portion 200 from affecting the passing of the power cord through the through hole 111.

[0044] After the power cord passes through the through hole 111 of the body 100, the convex portion 200 will form a concave portion on the outer side of the power cord, and the convex portion 200 is stuck in the concave portion to realize the mutual fixation of the power cord and the body 100. It should be understood that, in order to improve the fixation effect on the power cord, referring to Figure 4 and Figure 5 , a limiting surface 220 is formed on the convex portion 200. In some embodiments, referring to Figure 5 , the limiting surface 220 is perpendicular to the axis line of the through hole 111. Thus, after the power cord passes through the through hole 111 of the body 100, when the power cord is subjected to a pulling force along the second direction, the inner wall of the concave portion will abut against the limiting surface 220. Since the limiting surface 220 is perpendicular to the axis line, under the action of the pulling force, the inner wall of the concave portion gives the limiting surface 220 a pushing force towards the first direction. Correspondingly, the limiting surface 220 will give the inner wall of the concave portion a resistance towards the second direction to hinder the power cord from moving towards the first direction, thereby restricting the sliding of the power cord relative to the fixed clamp of the present application.

[0045] In some other embodiments, referring to Figure 7 , Figure 7 is Figure 5 a schematic diagram of some other embodiments of the convex portion 200 shown in the figure. The limiting surface 220 can also be inclined relative to the axis line of the through hole 111. Specifically, the limiting surface 220 is inclined along the second direction and towards the direction away from the axis line. It should be understood that when the power cord is subjected to a pulling force along the second direction, the part of the limiting surface 220 close to the axis line can abut against the inner wall of the concave portion and give the power cord a resistance force, and the resistance force has a component force towards the second direction, thereby being able to restrict the sliding of the power cord towards the second direction.

[0046] It should be noted that when the limiting surface 220 is perpendicular to the axis line, the contact area between the limiting surface 220 and the power cord can be increased, thereby improving the limiting effect of the limiting surface 220 on the power cord. Moreover, the corner end of the convex portion 200 defined by the limiting surface 220 can be a right angle or an acute angle with a relatively large angle, so as to prevent the outer side of the power cord from being cut by the corner end when the power cord is subjected to a tensile force in the second direction. Of course, when the limiting surface 220 is inclined relative to the axis line, the side of the convex portion 200 with the limiting surface 220 is concave, so that a certain amount of production materials can be saved.

[0047] For example, referring to Figure 4 , along the axial direction of the through hole 111, a first channel 1111 is formed at the position of the through hole 111 corresponding to the limiting surface 220, and a third channel 1113 is formed between the inner walls of the through hole 111. Along the first direction, the cross-sectional dimension of the first channel 1111 decreases, while the cross-sectional dimension of the third channel 1113 remains unchanged. When the power cord penetrates into the through hole 111 along the first direction, the end of the power cord slides in the third channel 1113 at first. After encountering the convex portion 200, the end of the power cord enters the first channel 1111. Since the cross-sectional dimension of the first channel 1111 gradually decreases, the power cord can easily enter the first channel 1111, and the extrusion force exerted on the power cord by the convex portion 200 gradually increases, enabling the convex portion 200 to clamp the power cord. Until the end of the power cord passes through the convex portion 200, the end of the power cord enters the third channel 1113, and the outer side of the power cord rebounds to match the cross-sectional dimension of the third channel 1113. Thus, when the power cord is subjected to a tensile force in the second aspect, it is difficult for the position of the power cord after passing through the convex portion 200 to move back from the third channel 1113 to the first channel 1111, so as to play a role in limiting the power cord.

[0048] In summary, the fixing clip of the present application can improve the fixing effect on the power cord passing through the through hole 111 through the convex portion 200. Moreover, a guiding surface 210 is formed on the convex portion 200 to slidably cooperate with the power cord penetrating along the first direction to guide the power cord through the through hole 111. And, a limiting surface 220 is formed on the convex portion 200 to abut against the power cord subjected to a tensile force in the second direction to limit the sliding of the power cord relative to the fixing clip of the present application.

[0049] In one application scenario of the fixing card of the present application, one end of the power cord passes through the through hole 111 along the first direction and is connected to the electrical device, and the other end of the power cord is connected to the socket. When a part of the power cord between the fixing card and the socket is subjected to a pulling force that drives the power cord to separate from the electrical device, the part of the power cord located in the through hole 111 will be subjected to a pulling force in the second direction. Under the clamping force of the convex part 200 and the limiting effect of the limiting surface 220 on the convex part 200, it is difficult for the power cord to slide relative to the fixing card. Thus, the part of the power cord between the fixing card and the electrical device will be fixed, thereby avoiding damage to the power cord caused by pulling or detachment from the electrical device, preventing accidental power-off of the electrical device and avoiding leakage problems. It should be understood that in order to improve the fixing effect on the power cord, multiple fixing cards can be set to fix the power cord. The fixing cards are arranged at intervals on the electrical device to fix multiple positions of the power cord through multiple fixing cards, thereby improving the fixing effect on the power cord. Moreover, the routing path of the power cord can be adjusted by adjusting the distribution mode of the fixing cards, so that the power cord is coiled on the bottom plate or the back plate of the electrical device to achieve the storage of the power cord, which can reduce the friction between the power cord and the electrical device or other objects, reduce the risk of power cord wear, and avoid the excessive length of the loose power cord, thereby reducing the risk of accidental injury to pedestrians or pets caused by tripping over the power cord. At the same time, a certain aesthetic property can be ensured. In addition, regarding the fixing position of the fixing card, in some other application scenarios, the fixing card of the present application can also be fixed on the wall, the ground or other devices beside the electrical device.

[0050] Regarding the setting positions of the guiding surface 210 and the limiting surface 220 relative to the convex part 200, in some embodiments, referring to Figure 5 , the guiding surface 210 and the abutting surface 230 are respectively formed at two ends of the convex part 200 along the axial direction of the through hole 111, and one side of the guiding surface 210 and the limiting surface 220 are respectively connected to the inner wall of the through hole 111. Thus, it is ensured that the power cord adapted to the size of the through hole 111 can easily slide onto the guiding surface 210 during the process of sliding along the inner wall of the through hole 111 to ensure the guiding effect of the guiding surface 210 on the power cord. For example, the minimum size of the first channel 1111 is the same as the size of the third channel 1113 to ensure the guiding effect of the guiding surface 210. And when the power cord is subjected to a pulling force in the second direction, the contact area between the power cord and the abutting surface 230 is large to ensure the fixing effect of the limiting surface 220 on the power cord. In some other embodiments, referring to Figure 8 , Figure 8 For Figure 5Schematic diagrams of other embodiments of the convex portion 200 shown therein, wherein the guiding surface 210 and the limiting surface 220 are located at positions close to both ends of the convex portion 200. The guiding surface 210 is connected to the inner wall of the through hole 111 through a straight surface perpendicular to the inner wall of the through hole 111, and the limiting surface 220 is connected to the inner wall of the through hole 111 through an inclined surface inclined relative to the inner wall of the through hole 111.

[0051] Regarding the specific form of the guiding surface 210, in some embodiments, referring to Figure 5 , the guiding surface 210 is an arc surface, and along the first direction, the included angle between the tangent of the arc surface and the first direction decreases, so that the arc surface protrudes outward. It should be understood that setting the guiding surface 210 as an arc surface can reduce the friction between the power cord and the arc surface, so that the process of the power cord entering the through hole 111 is smoother, and the risk of power cord breakage is reduced. In some other embodiments, compared with the embodiment shown in Figure 5 , the difference is that along the first direction, the included angle between the tangent of the arc surface and the first direction increases, so that the arc surface is concave inward. In still some other embodiments, compared with the embodiment shown in Figure 5 , the difference is that the guiding surface 210 is set as a flat inclined surface.

[0052] In order to increase the contact area between the convex portion 200 and the power cord and improve the fixing effect of the convex portion 200 on the power cord, in some embodiments, referring to Figure 5 , an abutting surface 230 is formed on one side of the convex portion 200. The abutting surface 230 is arranged on the side of the convex portion 200 close to the axis line. The abutting surface 230 is located between the guiding surface 210 and the limiting surface 220, and the abutting surface 230 is parallel to the axis line of the through hole 111. It should be understood that by providing the abutting surface 230 parallel to the axis line, the size of the convex portion 200 in the first direction is increased, so as to increase the contact area between the convex portion 200 and the power cord, and increase the friction between the convex portion 200 and the power cord when the power cord is subjected to a tensile force in the second direction. And when the limiting surface 220 is perpendicular to the axis line of the through hole 111, the corner end defined by the limiting surface 220 and the abutting surface 230 on the convex portion 200 is a right angle, so as to avoid forming an acute angle that may cut the power cord when the power cord is subjected to a tensile force, and avoid forming an obtuse angle that may cause the abutting surface 230 to play a certain guiding role for the power cord subjected to a tensile force in the second direction.

[0053] For example, referring to Figure 4, along the axial direction of the through hole 111, a second channel 1112 is formed at the position corresponding to the abutting surface 230 in the through hole 111. The cross-sectional dimension of the second channel 1112 remains unchanged, and is the same as the maximum cross-sectional dimension of the first channel 1111, and smaller than the cross-sectional dimension of the third channel 1113. Thus, after the power line passes through the first channel 1111 along the first direction, it can enter the second channel 1112, and then enter the third channel 1113 from the second channel 1112, so as to increase the friction between the convex portion 200 and the power line while reducing the influence on the power line penetrating along the first direction.

[0054] In some other embodiments, referring to Figure 9 , Figure 9 is Figure 5 a schematic diagram of some other embodiments of the convex portion 200 shown in

[0055] In some other embodiments, referring to Figure 6 , Figure 6 is Figure 5 a schematic diagram of some other embodiments of the convex portion 200 shown in

[0056] It should be understood that in order to ensure that the power line can pass through the second channel 1112 along the abutting surface 230, in some embodiments, referring to Figure 5 , one side of the abutting surface 230 is directly connected to the side of the limiting surface 220 closest to the axis, so that the minimum distance between the limiting surface 220 and the axis is equal to the minimum distance between the abutting surface 230 and the axis, so that the power line can pass through the second channel 1112 smoothly.

[0057] In some other embodiments, referring to Figure 10 , Figure 10 is Figure 5 a schematic diagram of some other embodiments of the convex portion shown in

[0058] It should be noted that regarding the definition of the distance between the limiting surface 220 and the axis, a circle tangent to the axis is drawn with any point on the limiting surface 220 as the center. Among them, the radius of the circle is the distance between the limiting surface 220 and the axis, and the radius of the circle with the smallest formed radius is the minimum distance between the limiting surface 220 and the axis.

[0059] Similarly, regarding the definition of the distance between the abutting surface 230 and the axis line, a circle tangent to the axis line is drawn with any point on the abutting surface 230 as the center. Among them, the radius of the circle is the distance between the abutting surface 230 and the axis line, and the radius of the circle with the smallest formed radius is the minimum distance between the abutting surface 230 and the axis line. Of course, since the abutting surface 230 is parallel to the axis line, a straight line perpendicular to both the abutting surface 230 and the axis line is drawn, and the distance between the intersection point between the straight line and the abutting surface 230 and the intersection point between the straight line and the axis line is the minimum distance between the abutting surface 230 and the axis line.

[0060] In order to further improve the fixing effect on the power cord, referring to Figure 4 , a plurality of convex portions 200 can be provided on the inner wall of the through hole 111, and the convex portions 200 are distributed along the axial direction of the through hole 111. It should be understood that in some embodiments, referring to Figure 4 , there are three convex portions 200. In other embodiments, the convex portions 200 can also be two or more than four, which is not limited herein. It can be understood that when a plurality of convex portions 200 are provided, when the power cord passes through the through hole 111, it sequentially passes through the plurality of convex portions 200 and is in sliding fit with the guiding surfaces 210 of the plurality of convex portions 200. After the power cord passes through the through hole 111, the plurality of convex portions 200 in the through hole 111 respectively abut against the outer side of the power cord, thereby improving the fixing effect of the fixing clip of the present application on the power cord. When the power cord is subjected to a tensile force in the second direction, the limiting surfaces 220 of the plurality of convex portions 200 can respectively abut against different positions on the power cord to improve the limiting effect on the power cord.

[0061] In order to further improve the fixing effect on the power cord, referring to Figure 1 and Figure 4 , the convex portion 200 can be extended along the circumferential direction of the through hole 111. In some embodiments, referring to Figure 1 , the convex portion 200 extends along the circumferential direction of the through hole 111 and the head and tail are not connected, and the convex portion 200 is substantially in a C shape. In other embodiments, the head and tail of the convex portion 200 are connected, and the convex portion 200 is substantially annular. It can be understood that by extending the convex portion 200 along the circumferential direction of the through hole 111, the contact area between the convex portion 200 and the power cord is increased, thereby improving the fixing effect of the convex portion 200 on the power cord.

[0062] Regarding the specific form of the body 100:

[0063] In some embodiments, referring to Figure 1 and Figure 3, the body 100 includes a fixing part 110, a first connecting part 120 and a second connecting part 130. Both the first connecting part 120 and the second connecting part 130 are fixedly connected to the fixing part 110. Among them, the fixing part 110 is provided with a through hole 111 for passing through a power cord. Among them, the first connecting part 120 can be connected to the mounting structure 300. For example, the first connecting part 120 is threadedly connected or clamped to the mounting structure 300. The second connecting part 130 can be clamped to the mounting structure 300, so that the fixing part 110 is fixed relative to the mounting structure 300.

[0064] Referring to Figure 11 , Figure 11 is a schematic diagram of the cooperation between the fixing clip of the present application and the mounting structure 300. In a process of fixing the body 100 on the mounting structure 300, the second connecting part 130 is clamped into the mounting groove 310 of the mounting structure 300 to realize the pre-positioning of the body 100. Then, by moving the body 100, the threaded hole on the first connecting part 120 is communicated with the threaded hole on the mounting structure 300. Then, a fastener is passed through the threaded hole on the first connecting part 120 and the threaded hole on the mounting structure 300 to realize the threaded connection between the first connecting part 120 and the mounting structure 300. Thus, the second connecting part 130 is clamped to the mounting structure 300, and the first connecting part 120 is threadedly connected to the mounting structure 300, achieving the purpose of fixing the fixing clip to the mounting structure 300. Compared with the wire clip that uses at least two fasteners in the prior art, in the present application, only one fastener can be used to fix the body 100 on the mounting structure 300, saving the use of fasteners and reducing the production cost. In addition, it should be understood that the clamping process of the second connecting part 130 and the mounting structure 300 is simpler than the process of installing the fastener, so that a certain amount of installation time can be saved and the production efficiency can be improved. And, by first clamping the second connecting part 130 to the mounting groove 310 on the mounting structure 300 to realize the pre-positioning of the body 100, it should be understood that after the second connecting part 130 is clamped to the mounting groove 310, the positions of the threaded hole on the first connecting part 120 and the threaded hole on the mounting structure 300 correspond to each other or are close to each other. Only by slightly moving the second connecting structure can the threaded hole on the first connecting part 120 and the threaded hole on the mounting structure 300 correspond to each other, thus saving the time required to align the threaded hole on the first connecting part 120 and the threaded hole on the mounting structure 300, and further improving the production efficiency.

[0065] It should be noted that regarding the specific form of the mounting structure 300, the mounting structure 300 can be a plate, a rod or a housing on an electrical device, such as the bottom plate, the back plate or the side plate of an electrical device. The mounting structure 300 can also be other structures located near the electrical device, such as a table or a shelf. The mounting structure 300 can also be a wall surface or a ground surface.

[0066] It should be noted that, regarding the fixed connection manner of the fixing part 110, the first connection part 120, and the second connection part 130, in some embodiments, referring to Figure 1 , the fixing part 110, the first connection part 120, and the second connection part 130 are integrally formed. In other embodiments, the fixing part 110, the first connection part 120, and the second connection part 130 can also be adhesively connected or snap-connected.

[0067] Regarding the specific form of the second connection part 130:

[0068] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 and Figure 11 , the second connection part 130 is generally in an L shape. One end of the second connection part 130 far from the fixing part 110 passes through the notch 312 of the installation groove 310 and is located inside the installation groove 310, and can abut against the inner wall 311 of the installation groove 310, while the end of the second connection part 130 connected to the fixing part 110 is located inside the notch 312 of the installation groove 310 or passes through the installation groove 310. When the fixing clip in the present application is subjected to a pulling force that drives the second connection part 130 away from the installation groove 310, the second connection part 130 abuts against the inner wall 311 of the installation groove 310, thereby preventing the second connection part 130 from disengaging from the installation groove 310, so as to ensure the connection stability between the second connection part 130 and the installation groove 310.

[0069] In some embodiments, in order to further improve the connection stability between the second connection part 130 and the installation structure 300, referring to Figure 3 and Figure 11 , a stepped structure 132 is formed on one side of the second connection part 130. The stepped structure 132 has a plurality of connected connection surfaces 1321, and in the stepped structure 132, two adjacent connection surfaces 1321 intersect, and the plurality of connection surfaces 1321 are connected to form a stepped surface. In addition, referring to Figure 11, It should be noted that the inner wall 311 of the installation groove 310 intersects with the notch wall 3121 of the notch 312. Thus, in order to make the second connecting portion 130 connect stably, two adjacent connecting surfaces 1321 are respectively in contact with the inner wall 311 of the groove and the notch wall 3121 of the notch. When the fixing card of the present application is subjected to a pulling force that drives the fixing card away from the installation structure 300, one of the connecting surfaces 1321 is in contact with the inner wall 311 of the groove to limit the second connecting portion 130 from disengaging from the installation groove 310, and can cooperate with the first connecting portion 120 that is threadedly connected to the installation structure 300 to limit the movement of the fixing card to prevent the fixing card from separating from the installation structure 300; and when the fixing card of the present application is subjected to a force that drives the fixing card to translate relative to the installation structure 300, the other connecting surface 1321 can be in contact with the notch wall 3121 of the notch, and can cooperate with the first connecting portion 120 that is threadedly connected to the installation structure 300 to limit the translation of the fixing card to prevent the fixing card from shaking, thereby improving the connection stability between the second connecting portion 130 and the installation structure 300, so that the fixing card is stably connected to the installation structure 300.

[0070] For example, referring to Figure 11 , the above two intersecting connecting surfaces 1321 are defined as the first connecting surface 1321a and the second connecting surface 1321b. Among them, the first connecting surface 1321a and the second connecting surface 1321b intersect. The first connecting surface 1321a is used to be in contact with the notch wall 3121 of the notch, and the second connecting surface 1321b is used to be in contact with the inner wall 311 of the groove. When the fixing card of the present application is subjected to a pulling force that drives the fixing card away from the installation structure 300, the second connecting surface 1321b is used to be in contact with the inner wall 311 of the groove, and when the fixing card of the present application is subjected to a force that drives the fixing card to translate relative to the installation structure 300, the first connecting surface 1321a is in contact with the notch wall 3121 of the notch. In order to improve the limiting effect of the first connecting surface 1321a and the second connecting surface 1321b, the included angle between the first connecting surface 1321a and the second connecting surface 1321b is set to be the same as the included angle between the notch wall 3121 of the notch and the inner wall 311 of the groove, so that the first connecting surface 1321a is parallel to the notch wall 3121 of the notch, and the second connecting surface 1321b is parallel to the inner wall 311 of the groove, so as to increase the contact area between the first connecting surface 1321a and the notch wall 3121 of the notch, and increase the contact area between the second connecting surface 1321b and the inner wall 311 of the groove, and improve the limiting effect of the stepped structure 132.

[0071] Specifically, in order to improve the aesthetics, referring to Figure 11, the stepped structure 132 includes at least three connecting surfaces 1321. The third connecting surface 1321 is defined as the third connecting surface 1321c. Among them, the third connecting surface 1321c is connected to the side of the first connecting surface 1321a away from the second connecting surface 1321b and intersects with the first connecting surface 1321a. It should be noted that one side of the first connecting portion 120 abuts against the mounting surface of the mounting structure 300 to avoid a gap between the first connecting portion 120 and the mounting structure 300, so as to ensure the connection stability between the first connecting portion 120 and the mounting structure 300. The third connecting surface 1321c is parallel or flush with the mounting surface of the mounting structure 300 to block the gap between the side of the second connecting portion 130 away from the first connecting portion 120 and the notch wall 3121, improve the aesthetics, and can reduce the entry of dust into the mounting groove 310. It should be understood that the gap between the side of the second connecting portion 130 close to the first connecting portion 120 and the notch wall 3121 is blocked by the fixing portion 110 and a part of the first connecting portion 120.

[0072] It should also be understood that in order to prevent the fixing card from swinging at the position where the first connecting portion 120 is threadedly connected to the mounting structure 300, the width of the second connecting portion 130 can be set to be adapted to the width of the notch 312. Thus, when the fixing card is subjected to a force that drives the fixing card to translate in its width direction, both sides of the second connecting portion 130 in the width direction can abut against the notch wall 3121 to prevent the fixing card from swinging.

[0073] In some embodiments, in order to further improve the connection stability between the second connecting portion 130 and the mounting structure 300, refer to Figure 2 , Figure 2 For Figure 1 a perspective three-dimensional view of another angle of the fixing card in

[0074] Regarding the specific form of the first connecting portion 120:

[0075] In some embodiments, refer to Figure 1 ,Figure 3 and Figure 11 , a notch 112 is formed on the fixing part 110 to form a communicating through hole 111, so that the fixing part 110 is generally in a C shape. It should be understood that the fixing part 110 has a certain plasticity. Therefore, the fixing part 110 can be deformed by extruding the fixing part 110 to make the notch 112 shrink or close, so as to reduce the size of the through hole 111, so that the convex part 200 on the inner wall of the through hole 111 further clamps the power cord, so as to improve the fixing effect on the power cord. Correspondingly, the size of the through hole 111 in the initial state when the fixing part 110 is not stressed is set to be larger than the outer diameter of the power cord, that is, the cross-sectional size of the third channel 1113 is slightly larger than the outer diameter of the power cord in the initial state. When the power cord penetrates into the through hole 111, there is a gap between the power cord and the inner wall of the third channel 1113, so that the power cord can be easily penetrated into the through hole 111 to reduce the resistance of the convex part 200 to the power cord when it penetrates into the through hole 111. In addition, the cross-sectional size of at least one section in the first channel 1111 is larger than the outer diameter of the power cord. Therefore, during the process of the power cord penetrating into the through hole 111, the guiding effect of the guiding surface 210 on the power cord is ensured, and the convex part 200 can play a certain limiting effect on the power cord penetrating into the through hole 111 to prevent the power cord from shaking during the process of penetrating into the through hole 111. And after the fixing part 110 is stressed, the convex part 200 can further clamp the power cord to ensure the clamping force of the convex part 200 on the power cord.

[0076] Among them, in order to facilitate the deformation of the fixing part 110 under the extrusion force, the first connecting part 120 includes an independent first connecting block 121 and a second connecting block 122. The first connecting block 121 and the second connecting block 122 are fixedly connected to the outside of the fixing part 110, and the first connecting block 121 and the second connecting block 122 can be extruded to make the first connecting block 121 and the second connecting block 122 approach each other, thereby driving the fixing part 110 to deform, so that the fixing part 110 is stressed to make the notch 112 shrink or close, so that the convex part 200 clamps the power cord. It should be understood that a first connecting hole 1211 is formed on the first connecting block 121, and a second connecting hole 1221 is formed on the second connecting block 122. After the first connecting block 121 and the second connecting block 122 approach to clamp the power cord by the convex part 200, the fastener passes through the first connecting hole 1211, the second connecting hole 1221 and the threaded hole on the mounting structure 300, so that the first connecting part 120 and the second connecting part 130 are kept in a state where the notch 112 shrinks or closes, so that the convex part 200 keeps clamping the power cord, and at the same time, the first connecting block 121 and the second connecting block 122 can be fixed on the mounting structure 300.

[0077] It should be understood that, in order to improve the fixing effect of the fixing portion 110, when the first connecting block 121 and the second connecting block 122 approach each other, the notch 112 is closed, so that the size of the through hole 111 is shrunk to the minimum, thereby improving the clamping force of the convex portion 200 on the power cord, and ensuring that the inner wall of the through hole 111 contacts the outer side of the power cord, improving the frictional force between the inner wall of the through hole 111 and the power cord, so as to improve the fixing effect of the fixing portion 110 on the power cord.

[0078] It can also be understood that when the power cord passes through the through hole 111 and slides along the guiding surface 210, the convex portion 200 presses the outer side of the power cord. Correspondingly, the power cord gives a reaction force to the convex portion 200, so as to be able to increase the notch 112, thereby enlarging the through hole 111, which is beneficial for the power cord to pass through the through hole 111.

[0079] In some other embodiments, compared with Figure 1 the shown body 100, the difference is that the fixing portion 110 does not have a notch 112, the first connecting portion 120 is a single and integrally formed block, and a threaded hole is provided on the block for connecting with the installation structure 300 by cooperating with a fastener.

[0080] Regarding the setting positions of the first connecting block 121 and the second connecting block 122, in some embodiments, in order to facilitate the first connecting block 121 and the second connecting block 122 to drive the notch 112 to shrink, referring to Figure 1 、 Figure 3 and Figure 11 , two end portions are formed on the fixing portion 110 corresponding to the notch 112, and the first connecting block 121 and the second connecting block 122 are respectively arranged at the two end portions of the fixing portion 110, so that when the first connecting block 121 and the second connecting block 122 approach each other, it can easily drive the notch 112 to shrink. And, the side of the second connecting block 122 close to the first connecting block 121 is in close contact, to ensure the connection stability between the first connecting block 121 and the second connecting block 122, the side of the second connecting block 122 far from the first connecting block 121 is in close contact with the installation surface of the installation structure 300, to ensure the connection stability between the second connecting block 122 and the installation structure 300, and the second connecting block 122 is tangent to the end portion of the fixing portion 110, ensuring that the fixing portion 110 can be located outside the installation groove 310.

[0081] In some other embodiments, the first connecting block 121 and the second connecting block 122 may also not be arranged corresponding to the two end portions of the fixing portion 110, and are arranged at other positions outside the fixing portion 110, as long as the notch 112 can be shrunk when the first connecting block 121 and the second connecting block 122 approach each other.

[0082] The refrigeration device according to the second aspect embodiment of the present invention includes the fixing clip of the first aspect embodiment.

For example, the plate can be a bottom plate, a side plate or a back plate, etc. Another example is that the housing of other structures inside the refrigeration device is the housing of the power supply.
