[0049] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0050] The leaky cable installation fixture provided in this application refers to Figure 1 and Figure 3 As shown, it includes a device body 100 and a driving component 200 arranged on the device body 100, at least one clamping component 300 and at least one mounting member 400, and the driving component 200 includes a first driving shaft 210 and at least one second driving shaft 220 that are interconnected; wherein, the linkage means that the first driving shaft 210 and the second driving shaft 220 move simultaneously, and the first driving shaft 210 may drive the second driving shaft 220 to move, or the second driving shaft 220 may drive the first driving shaft 210 to move.

[0051] The mounting member 400 is used to be inserted into the bracket 10 of rail transit. The mounting member 400 is connected to the first driving shaft 210 . The first driving shaft 210 drives the mounting member 400 to move relative to the device body 100 to connect the mounting member 400 and the bracket 10 .

[0052] The clamping assembly 300 includes a first clamping member 310 and a second clamping member 320, both of which are arranged on the second driving shaft 220. The second driving shaft 220 drives at least one of the first clamping member 310 and the second clamping member 320 to move relative to the other, so that the first clamping member 310 and the second clamping member 320 jointly clamp the leaky cable.

[0053] It should be noted that the leaky cable installation fixture provided in the embodiment of the present application can be used not only to install leaky cables, but also to install electric wires, optical cables, and electrical cables, etc. The embodiment of the present application does not impose too many restrictions on this.

[0054] At least one second drive shaft 220 and at least one clamping assembly 300, referring to Figure 1 and Figure 3 As shown, the number of the second drive shaft 220 and the clamping assembly 300 can both be one; Figure 2 and Figure 4 As shown, the number of the second drive shafts 220 and the number of the clamping assemblies 300 may also be two, the two second drive shafts 220 are symmetrically arranged on both sides of the first drive shaft 210, and each clamping assembly 300 is correspondingly arranged on the second drive shaft 220.

[0055] At least one mounting member 400 is provided. There may be one mounting member 400 or two mounting members 400. The embodiment of the present application does not impose too many restrictions on this.

[0056] It should be noted that an included angle (i.e. Figure 1 As indicated by the arrow α in the middle, for example, the angle may be 80°, 90° or 100°, or other angles, and the embodiments of the present application do not impose too many restrictions on this.

[0057] It should also be noted that the drive assembly 200 may also include a motor 230, and the first drive shaft 210 may be driven to rotate by the motor 230, or the first drive shaft 210 may be driven to rotate manually, and the embodiments of the present application do not impose too many restrictions on this.

[0058] Specifically, refer to Figure 1 and Figure 3As shown, when installing the leaky cable, the installation member 400 can be first inserted into the bracket 10 of the rail transit, that is, inserted into the through hole 11 of the bracket 10, and the leaky cable to be installed is placed between the first clamping member 310 and the second clamping member 320; or the leaky cable to be installed can be placed between the first clamping member 310 and the second clamping member 320, and then the installation member 400 is inserted into the bracket 10 of the rail transit. Then the first drive shaft 210 is driven along Figure 1 The first drive shaft 210 rotates in the positive direction of the arrow W, and the rotating first drive shaft 210 drives the mounting member 400 along Figure 1 Move in the positive direction of X or the reverse direction of X as indicated by the middle arrow until the mounting member 400 is connected to the bracket 10 , and the leaky cable mounting fixture is fixed on the bracket 10 .

[0059] At the same time, the rotating first drive shaft 210 drives the second drive shaft 220 to rotate along Figure 1 The rotating second drive shaft 220 drives at least one of the first clamping member 310 and the second clamping member 320 to rotate relative to the other along the positive direction of V. Figure 1 The first clamping member 310 and the second clamping member 320 move in the positive direction of Y or the reverse direction of Y as indicated by the middle arrow, so that the first clamping member 310 and the second clamping member 320 are close to each other. When the mounting member 400 is connected to the bracket 10, the first clamping member 310 and the second clamping member 320 clamp the leaky cable together, thereby realizing the installation of the leaky cable. The method for installing the leaky cable is simple, the operation is convenient, and the installation efficiency is improved.

[0060] It can be understood that since at least one of the first clamping member 310 and the second clamping member 320 moves relative to the other, so that the distance between the first clamping member 310 and the second clamping member 320 is adjustable, the first clamping member 310 and the second clamping member 320 can adapt to leaky cables of different sizes and shapes, thereby improving the applicability of the leaky cable installation fixture.

[0061] In some embodiments, reference Figure 1 As shown, the leaky cable installation fixture also includes a transmission assembly 500, which includes a first gear 510 and a second gear 520. The first gear 510 is sleeved on the first drive shaft 210, and the second gear 520 is sleeved on the second drive shaft 220. The first gear 510 is meshed with the second gear 520.

[0062] Specifically, the meshing of the first gear 510 and the second gear 520 can effectively transmit force and motion, so as to transmit the force of the first drive shaft 210 to the second drive shaft 220. The first gear 510 and the second gear 520 can change the direction of the force by setting an angle, so that the first drive shaft 210 rotating in the W direction can drive the second drive shaft 220 to rotate in the V direction, so that when the first drive shaft 210 drives the mounting member 400 to move relative to the device body 100, it can also drive the first clamping member 310 and the second clamping member 320 to approach each other through the second drive shaft 220.

[0063] It can be understood that the driving direction can be changed by meshing the first gear 510 and the second gear 520 and setting the included angle to adapt to different installation angles and environments, thereby improving the flexibility of the leaky cable installation.

[0064] In some embodiments, reference Figure 1 As shown, at least one first external thread segment 211 is provided on the first drive shaft 210 , and the mounting member 400 has a first internal thread 410 matching the first external thread segment 211 , and the mounting member 400 and the first drive shaft 210 are connected to the first external thread segment 211 via the first internal thread 410 .

[0065] It can be understood that rotational motion can be converted into linear motion through threaded connection. By rotating the first drive shaft 210, the engagement of the first outer thread segment 211 and the first inner thread 410 can realize linear movement of the mounting member 400, so that the mounting member 400 can be connected to the bracket 10 to achieve fixation of the mounting device.

[0066] The engagement of the first outer thread segment 211 and the first inner thread 410 provides a high-strength connection, which can withstand large axial forces and torques to prevent the mounting member 400 from loosening or falling off, thereby improving the stability and reliability of the device.

[0067] The position of the mounting member 400 can be conveniently adjusted by rotating the first drive shaft 210 and locked by threads when the desired position is reached, making the installation process more flexible and controllable, and the operator can make precise adjustments as needed.

[0068] In some embodiments, reference Figure 1 and Figure 2 As shown, the mounting member 400 is provided with an abutment portion 420 , which is located at an end of the mounting member 400 away from the first internal thread 410 , and is used to abut against the surface of the bracket 10 .

[0069] Alternatively, if Figure 1 As shown, the abutting portion 420 is an L-shaped structure. Of course, in other embodiments, the abutting portion 420 may also be other shapes, which is not limited in the present application.

[0070] It can be understood that by providing the abutment portion 420 on the mounting member 400 , when the abutment portion 420 abuts against the surface of the bracket 10 , the mounting member 400 can be prevented from being separated from the bracket 10 of the rail transit, thereby achieving the connection between the mounting member 400 and the bracket 10 .

[0071] It should be noted that the design of the abutment portion 420 makes the installation process easier. The operator only needs to insert the mounting member 400 into the through hole 11 until the abutment portion 420 abuts against the surface of the bracket 10. There is no need for complicated adjustment and positioning, which improves installation efficiency and reduces operating difficulty.

[0072] In some embodiments, reference Figure 1 and Figure 2 As shown, the device body 100 has a first limiting hole 110 , and the abutting portion 420 extends out of the device body 100 through the first limiting hole 110 .

[0073] It should be noted that the abutment portion 420 on the mounting member 400 extends through the first limiting hole 110 on the device body 100, so that the position and direction of the mounting member 400 are limited within the first limiting hole 110. Figure 1 When rotating in the direction W as indicated by the middle arrow, the first limiting hole 110 can effectively guide the movement path of the abutting portion 420 so that the mounting member 400 moves along the extension direction of the first driving shaft 210 (ie Figure 1 The positive direction of X or the negative direction of X as shown by the arrow in the figure.

[0074] Optionally, in Figure 1 In the X direction indicated by the middle arrow, the length of the first limiting hole 110 is greater than the length of the through hole 11 on the bracket 10. This design can reduce the resistance encountered by the abutting portion 420 during movement, ensuring that the subsequent abutting portion 420 can abut against the bracket 10.

[0075] In some embodiments, reference Figure 1 and Figure 2 As shown, the number of the first external thread segments is two, the number of the mounting members 400 is two, and the first internal threads 410 of the mounting members 400 are correspondingly connected to the first external thread segments 211 .

[0076] The first driving shaft 210 drives the two mounting members 400 to move closer to or away from each other through the first outer thread segment 211 .

[0077] It can be understood that the leaky cable installation fixture is connected to the bracket 10 via two installation members 400, which improves the connection strength between the device and the bracket 10 and improves the reliability of the device.

[0078] It should be noted that the two first outer thread segments 211 on the first drive shaft 210 have opposite rotation directions. Figure 1 When the first drive shaft 210 rotates in the positive direction of W, the two mounting members 400 can be driven to move in opposite directions, and the two mounting members 400 move away from each other until they abut against the surface of the bracket 10, thereby improving the installation efficiency and reducing the operation time. Figure 1 When the W shown by the middle arrow rotates in the opposite direction, the two mounting parts 400 can be driven to approach each other.

[0079] The movements of the two mounting members 400 in opposite directions can balance each other, thereby enhancing the structural stability of the device, improving the durability of the device, and ensuring a smooth installation process.

[0080] In some embodiments, reference Figure 1 and Figure 2 As shown, at least one second external thread segment 221 is provided on the second driving shaft 220 , and one of the first clamping member 310 and the second clamping member 320 has a second internal thread 311 matching the second external thread segment 221 , and the second internal thread 311 is connected to the second external thread segment 221 .

[0081] The second driving shaft 220 drives at least one of the first clamping member 310 and the second clamping member 320 to move relative to the other through the second outer threaded section 221 .

[0082] It can be understood that the threaded connection can convert rotational motion into linear motion. By rotating the second drive shaft 220, the engagement of the second outer thread segment 221 and the second inner thread 311 can realize the linear movement of the first clamping member 310 or the second clamping member 320 to adjust the distance between the first clamping member 310 and the second clamping member 320, thereby achieving the clamping of the leaky cable.

[0083] The engagement of the second outer thread segment 221 and the second inner thread 311 provides a high-strength connection, which can withstand large axial forces and torques, thereby ensuring that the first clamping member 310 and the second clamping member 320 will not loosen or fall off during the process of clamping the leaky cable, thereby improving the stability and reliability of the device.

[0084] In some embodiments, the first clamping member 310 and the second clamping member 320 are both provided with a clamping portion 312, and the clamping portion 312 is used to clamp the leaky cable.

[0085] By providing the clamping portion 312 for clamping the leaky cable, the clamping portion 312 can provide a firm gripping force, thereby improving the stability and reliability of the installation, and ensuring that the leaky cable will not slide or loosen during use.

[0086] It should be noted that the clamping portion 312 may be made of a material having a certain degree of flexibility or a soft material to avoid damaging the surface of the leaky cable.

[0087] The clamping portion 312 can be configured to accommodate leaky cables of different sizes and shapes. By adjusting the shape and size of the clamping portion 312, effective clamping of leaky cables of various specifications can be achieved, thereby increasing the applicability of the device and enabling it to be used in different rail transit systems. For example, the clamping portion 312 can be arc-shaped or in other shapes, and the embodiments of the present application do not impose too many restrictions on this.

[0088] In some embodiments, reference Figure 1 As shown, the clamping assembly 300 further includes at least one elastic member 330 , and at least one of the first clamping member 310 and the second clamping member 320 is connected to the device body 100 via the elastic member 330 .

[0089] For example, the first clamping member 310 is connected to the device body 100 through the elastic member 330. When the second driving shaft 220 drives the first clamping member 310 to move along the Figure 1 When the elastic member 330 moves in the opposite direction of the direction Y indicated by the middle arrow, the elastic member 330 is stretched by the force of the first clamping member 310; when the second driving shaft 220 drives the first clamping member 310 to move along Figure 1 When moving in the positive direction of Y indicated by the middle arrow, the elastic member 330 recovers its elastic deformation.

[0090] The second clamping member 320 is connected to the device body 100 through the elastic member 330. When the second driving shaft 220 drives the second clamping member 320 along the Figure 1 When the elastic member 330 moves in the positive direction of Y indicated by the middle arrow, the elastic member 330 is stretched by the force of the first clamping member 310; when the second driving shaft 220 drives the second clamping member 320 to move along Figure 1 When moving in the opposite direction of Y indicated by the middle arrow, the elastic member 330 recovers its elastic deformation.

[0091] It should be noted that the elastic member 330 may be a spring or other elastic parts, and the embodiment of the present application does not impose too many restrictions on this.

[0092] It should also be noted that a plug-in hole can also be set on the device body 100, and part of the first clamping member 310 and part of the second clamping member 320 can be inserted into the plug-in hole. When the second driving shaft 220 drives the first clamping member 310 or the second clamping member 320 to move, the first clamping member 310 or the second clamping member 320 can move relative to the plug-in hole.

[0093] In some embodiments, reference Figure 2 and Figure 4As shown, the number of the second driving shafts 220 is two, and the two second driving shafts 220 are symmetrically arranged on both sides of the first driving shaft 210 .

[0094] Specifically, the two second drive shafts 220 are symmetrically arranged on both sides of the first drive shaft 210, and each clamping assembly 300 is correspondingly arranged on the second drive shaft 220. The second drive shaft 220 correspondingly drives the clamping assembly 300 to clamp the leaky cable, so that two leaky cables can be installed at the same time, thereby improving the installation efficiency.

[0095] In some embodiments, the leaky cable installation fixture also includes a limit member 600, which is arranged on the first drive shaft 210. The device body 100 has a second limit hole 120, and part of the limit member 600 is used to be inserted into the second limit hole 120 to limit the first drive shaft 210 on the device body 100.

[0096] Exemplarily, the stopper 600 may be an anti-loosening tooth, which may be sleeved on the first drive shaft 210. When the mounting member 400 abuts against the peripheral side of the through hole 11, the end of the anti-loosening tooth is inserted into the second stopper hole 120 to limit the first drive shaft 210 on the device body 100, thereby preventing the first drive shaft 210 from continuing to rotate, thereby ensuring the reliability and safety of the device; that is, after the first drive shaft 210 rotates to the right position, the position of the first drive shaft 210 is locked by the stopper 600, thereby locking the relative position of the abutment portion 420 and the bracket 10, and the relative position of the clamping assembly 300 and the leaky cable.

[0097] It can be understood by those skilled in the art that the leaky cable installation fixture provided in the present application is provided with a device body 100 and a drive assembly 200, at least one clamping assembly 300 and at least one mounting member 400 disposed on the device body 100, wherein the drive assembly 200 includes a first drive shaft 210 and at least one second drive shaft 220, and the first drive shaft 210 is connected to the second drive shaft 220.
