[0055] The features, effects, etc. of the cable bracket or harness bracket of the utility model are described in detail below in conjunction with the accompanying drawings. The "left" and "right" mentioned in the text refer to the left and right sides observed in the direction facing the drawing, and the "inside" and "outside" refer to the forward direction and the backward direction observed in the direction facing the drawing.

[0056] like Figure 1 As shown in the figure, a front view of an embodiment of a cable bracket or harness bracket of the utility model is shown, and the bracket is clamped on the applied equipment or device m in the state shown in the figure for quick disassembly and assembly. The application scenarios of the bracket of the utility model include arranging test cables or harnesses on the equipment or device when performing performance testing on the equipment or device, for example, in the case of flight testing, it is used to install test cables on the aircraft structure.

[0057] The following is further combined Figure 1 and Figure 3 The cable bracket or harness bracket of the utility model is described in detail as shown. The bracket includes a pair of clamping arms, which are a left clamping arm 1 and a right clamping arm 2 when viewed from the direction facing the drawing. The left clamping arm 1 has a clamping section 11 and a manipulation section 12, with a pivot section 13 therebetween; similarly, the right clamping arm 2 also includes a clamping section 21, a manipulation section 22 and a pivot section 23. In the embodiment shown in the figure, the clamping section 11 of the left clamping arm and the clamping section 21 of the right clamping arm are in opposite arc shapes, so that these clamping sections can cooperate to form a roughly circular cable or harness accommodating space A (such as Figure 1 As shown). However, those skilled in the art will appreciate that the shapes of the clamping sections 11 and 21 may also adopt corresponding folded line shapes to form a diamond-shaped cable or harness accommodating space therebetween; or may also adopt corresponding L shapes to form a square cable or harness accommodating space therebetween; of course, the shapes of the clamping sections 11 and 21 may also be changed accordingly according to the actual shape requirements of the cable or harness.

[0058] In addition, if Figure 3 As shown, the pivoting sections 13 and 23 are respectively in the shape of rings, and a pin 3 passes through each pivoting section 13 and 23 to pivotally connect the left clamping arm 1 and the right clamping arm 2 together (as shown in FIG. Figure 1 and Figure 2 As shown), the left and right clamping arms can rotate around the pin 3, so that the bracket is in a clamping or opening state. Figure 1 As shown, in the clamping state, the left and right clamping sections 11 and 21 are retracted to form a cable or harness accommodating space A therebetween, and the ends thereof are clamped on equipment or devices, such as aircraft structural parts. Figure 2 As shown, in the open state, the left and right clamping sections 11 and 21 are away from each other, and their ends are separated from equipment or devices, and rapid disassembly is achieved. Pivoting sections 13 and 23 can also adopt other forms, such as sheets, which have holes for the pin 3 to pass through.

[0059] More specifically, as shown in Figure 1 and Figure 3 The ends 111 of the clamping segments 11 of the left clamping arm 1 and the ends 211 of the clamping segments 21 of the right clamping arm 1 are covered with rubber caps 4 and 4', which can avoid damaging the surface of the equipment or device, such as the surface of an aircraft structural member, due to the clamping force in the clamping state. Those skilled in the art can also understand that the ends 111 and 211 can also be made into flat clamping surfaces (not shown in the figure) to avoid leaving indentations on the surface of the structural member.

[0060] According to an embodiment of the present invention, the bracket further includes a clamping assembly, which is connected between the operating segments 13 and 23 of the left clamping arm 1 and the right clamping arm 2 to push or close the operating segments 12 and 13 so that the clamping segments 1 rotate around the pin shaft 3 to the clamping or opening state.

[0061] In Figure 3 The embodiment shown, an embodiment of the clamping assembly 5 is shown, including a left screw 51 and a right screw 52. The left screw 51 is fixed on the inner side surface of the operating segment 12 of the left clamping arm 1, and the right screw 52 is fixed on the inner side surface of the operating segment 22 of the right clamping arm 2. A nut 53 is engaged between the left screw 51 and the right screw 52. The left screw 51 and the right screw 52 are provided with external threads in opposite directions, and the nut 53 is provided with two internal thread portions 531 and 532 corresponding to the external threads on the left screw 51 and the right screw 52 respectively. Due to the engagement of the nut 53 with the left and right screws 51 and 52, when the nut 53 is rotated inward or outward in the direction of the drawing plane, the left screw 51 and the right screw 52 can be made to approach or move away from each other, driving the operating segments 12 and 22 to approach or move away from each other, so that the clamping segments 11 and 21 reach the clamping or opening state.

[0062] In Figure 1 the embodiment shown, to further maintain the clamping state, a locking mechanism is further included. Specifically, as shown in Figure 3 The locking mechanism includes pin holes 521 provided on the left screw 51 and the right screw 52 and a pin hole 533 provided on the nut 53. Both ends of at least one pin 54 are inserted into the pin hole 511 of the left screw and the pin hole 533 of the nut 53, or inserted into the pin hole 521 of the right screw 52 and the pin hole 533 of the nut 53. In this way, in addition to the acting force of the thread fit itself, the cooperation between the nut and the screw can be further prevented from loosening by the action of the pin 54, making the clamping of the bracket more reliable. When it is necessary to remove the bracket, the pin 54 can also be conveniently removed and the nut 53 can be turned to move the left and right clamping segments 11 and 21 away from each other, quickly disengaging from the equipment or device.

[0063] According to the present invention, as shown inFigure 4 As shown, an alternative embodiment 5' of the clamping assembly includes a screw 51' and a pin 52'. The screw 51' is fixed to the inner side of the operating section 12 or 22 of one of the left clamping arm 1 or the right clamping arm 2. As shown in the figure, the screw 51' is fixed to the inner side of the operating section 12 of the left clamping arm 1; the pin 52' is fixed to the inner side of the operating section 22 or 21 of one of the right clamping arm 2 or the left clamping arm 1. As shown in the figure, the pin 52' is fixed to the inner side of the operating section 22 of the right clamping arm 2. One end of a sleeve 53' is engaged with the screw 51' by an internal thread portion 531', and the other end portion 532' of the sleeve 53' is sleeved on the pin 52'. Due to the engagement and cooperation of the sleeve 53', the screw 51' and the pin 52', when the sleeve 53' is rotated inward or outward in the direction of the drawing plane, the screw 51' and the pin 52' can be moved closer to or away from each other, driving the operating sections 12 and 22 to move closer to or away from each other, so that the clamping sections 11 and 21 reach the clamping or opening state.

[0064] Correspondingly, in Figure 4 the embodiment shown, the clamping assembly further includes a locking mechanism. The locking mechanism includes a pin hole 511' provided on the screw 51', a pin hole 521' provided on the pin 52', and a pin hole 533' provided on the sleeve 53'. Both ends of at least one pin 54 (not shown) are inserted into the pin hole 511' of the screw 51' and the pin hole 533' of the sleeve 53', or into the pin hole 521' of the pin 52' and the pin hole 533' of the sleeve 53'. In this way, in addition to the acting force of the thread fit itself, the cooperation between the sleeve and the left screw can be further prevented from loosening by relying on the action of the pin, making the clamping of the bracket more reliable. When the bracket needs to be removed, the pin can also be conveniently removed and the sleeve 53' can be turned to move the left and right clamping sections 11 and 21 away from each other, quickly detaching from the equipment or device. Those skilled in the art can also understand that although Figure 4 in the embodiment shown, the left screw and the right pin are used, but an alternative method of using a right screw and a left pin can also be adopted. In this state, the right end portion of the sleeve 53' is an internal thread portion, and the left end is directly sleeved on the pin.

[0065] The foregoing description has set forth many features and advantages of the bracket of the present invention, including various alternative methods and details of the structure and function of the device and / or method. The present disclosure is only intended to be exemplary and is not intended to be exhaustive. It will be apparent to those skilled in the art that various modifications can be made within the scope of the principles of the present disclosure and within the broadest scope indicated by the broad upper meaning of the terms expressing the appended claims. To the extent that these various modifications do not depart from the spirit and scope of the appended claims, these modifications are intended to be included herein.
