[0030] The cable hanger and cable clamping device provided by at least one embodiment of the present application, the cable hanger includes a mounting seat with an opening and a closing portion configured on the mounting seat to open or close the opening; the closing portion includes a cover plate that can connect the two ends of the opening of the mounting seat, one end of the cover plate is rotatably connected to one end of the opening of the mounting seat, and the other end of the cover plate is clamped to the other end of the opening of the mounting seat; the cover plate is configured with a positioning port and a sliding airbag, the sliding airbag is installed on the positioning port through a dialing member and is located on the side of the cover plate close to the opening; the positioning port is configured with a limiting member, the dialing member includes at least one dialing piece connected to the sliding airbag, and a limiting protrusion matching the limiting member is configured on the side of the dialing piece close to the limiting member, and the limiting protrusion is engaged with the limiting member to fix the sliding airbag at a preset position of the positioning port.

[0031] In the cable hanger provided by the embodiment of the present application, the cover plate can seal the opening of the mounting seat to form a stable cable accommodation space, and the positioning port on the cover plate and the sliding airbag that can be displaced and fixed relative to the positioning port can adjust the division of the accommodation space according to different requirements, and can adapt to the fixation of cables of different specifications, with strong flexibility.

[0032] The cable hanger and cable clamping device provided by the embodiment of the present application will be described below through several specific embodiments.

[0033] At least one embodiment of the present application provides a cable hanger 100, Figure 1 and Figure 2 collectively show the three-dimensional structural schematic diagrams of the cable hanger 100 in different states, such as Figure 1 and Figure 2As shown, the cable hanger 100 includes a mounting seat 110 and a sealing portion 120; wherein the mounting seat 110 is an arc-shaped, U-shaped or other structure with an opening, and the two ends of the opening serve as the connection positions of the sealing portion 120 for the sealing portion 120 to be installed and open or close the opening. The sealing portion 120 includes a cover plate 121 that is approximately rectangular, and the two ends of the cover plate 121 are respectively connected to the two ends of the opening of the mounting seat 110. In order to realize the flexible function of opening or closing, the connection modes of the two ends of the cover plate 121 and the two ends of the mounting seat 110 are respectively a rotating connection mode that can be rotated and a clamping mode that forms a fixed effect; specifically, the rotating connection mode can be realized by a pin connection in the simplest way, and the clamping mode is realized by the cooperation of the undercut 125 and the bayonet 111. In this implementation mode, the cover plate 121 can be rotated with the pin connection end as the center to open and close the opening of the mounting seat 110, and the undercut 125 and the bayonet 111 can fix the cover plate 121 in the sealed state to prevent loosening.

[0034] In addition, the cover plate 121 has a positioning opening 122 that runs through the top and bottom. The positioning opening 122 is provided with a lever 124 that is connected to the sliding airbag 123. During the rotation and sealing process of the cover plate 121, the sliding airbag 123 is finally placed inside the mounting seat 110 to fix the cable or divide the installation space by squeezing. In the embodiment of the present application, the sliding airbag 123 can also be moved on the positioning opening 122 to adjust its relative position and fix it. This function is conducive to simply and quickly adjusting the cable installation space (division).

[0035] In the above embodiment, the effect of the sliding airbag 123 sliding and being fixed on the positioning opening 122 is achieved by structures such as the limiting member 1221, the limiting protrusion 1242 and the paddle 1241. In order to enable those skilled in the art to fully understand and implement this embodiment, the present application also provides some embodiments for illustration.

[0036] For example, Figure 3 An embodiment of the configuration structure of the positioning port 122 and the sliding airbag 123 in the cable hanger 100 of the present application is shown. Figure 1 , Figure 2 See also Figure 3, within the rectangular parallelepiped space formed by the positioning port 122, there are two racks arranged in parallel with each other and located on opposite sides of the positioning port 122 respectively - it is also possible to only set one rack at one side. The dialing member 124 is arranged in the form of a dial piece 1241, and a protrusion is arranged on the side close to the tooth surface of the rack. When the protrusion is stuck into the tooth gap, it can play a limiting role, so that the dial piece 1241 and the sliding airbag 123 connected to the dial piece 1241 are fixed relative to the positioning port 122 and no longer move, thus realizing the fixation of the sliding airbag 123. When making a position adjustment, the dial piece 1241 can be pinched to cause a slight deformation to release the limiting effect of the protrusion, so that the dial piece 1241 and the sliding airbag 123 connected thereto can move relative to the rack (or the positioning port 122), and flexibly match the installation requirements of cables of different specifications.

[0037] It should be noted that the setting method of the rack in this application is not limited to the above embodiments and the illustrated content. The embodiments and the illustrated content only exist for the purpose of explaining the technical solution of this application. For example, the number of racks set can be two parallel ones on both sides, or one on one side; the shape of the rack can be a wavy protrusion or a chamfered tooth at a certain angle; the setting form of the rack can be with the tooth surface facing up (i.e., Figure 3 as shown in), or with the tooth surface facing sideways or opposite (under the condition that there are two racks on both sides). Of course, those skilled in the art can understand that when the tooth surfaces are opposite, the positions of other corresponding cooperating components will also change accordingly without affecting the actual effect, such as the configuration position of the protrusion on the dial piece 1241.

[0038] For example, in some embodiments, as Figure 3 shown, the dialing member 124 further includes a connecting block 1243. The dial piece 1241 is connected to the sliding airbag 123 through the connecting block 1243. The connecting block 1243 passes through the positioning port 122 and is configured as a fixed end 1244 on the side away from the sliding airbag 123. The dial piece 1241 passes through the positioning port 122 through the connecting block 1243, so that it can be arranged above the positioning port 122. The connecting block 1243 can not only save the connection space, but also form a fixed end 1244 at the other end, which is convenient for the pinching operation during adjustment.

[0039] Furthermore, as Figure 3 shown, the fixed end 1244 has the same shape as the dial piece 1241 and is arranged on the side of the connecting block 1243 away from the sliding airbag 123. The pinching operation position formed in this form has a more uniform force and is beneficial for labor-saving operation.

[0040] Furthermore, the shifter 124 can also be configured as two shifters 1241 with the same structure and symmetrical with the connecting block 1243 as the axis. Under the limiting action of the two protrusions, the fixing effect is better; when adjusting the position, the opposite clamping action of the two shifters 1241 can also reduce the torque, making the operation more labor-saving.

[0041] It is particularly noted that in the above-mentioned embodiments, the paddle 1241 is preferably made of a material having an elastic modulus to facilitate pinching or clamping to form a slight deformation to release the locked state, and the embodiments of the present application do not specifically limit this.

[0042] In addition, the drawings of the present application are modeled and generated based on actual production use, and the details shown therein cannot be regarded as limitations of the present application. Without departing from the technical solution of the present application, any structural changes that can realize the technical solution of the present application should be included in the protection scope of the present application.

[0043] For example, in some embodiments, Figure 1 As shown, a fixing airbag 130 is disposed on one side of the mounting seat 110 near the opening. The fixing airbag 130 can cooperate with the position adjustment of the sliding airbag 123 to form a stronger fixing effect on the installed cable. Figure 1 and Figure 2 In the illustrated embodiment, the fixing airbags 130 are disposed at both ends of the inner wall of the mounting seat 110 , and openings may be formed on the fixing airbags 130 to form snap-in notches 111 for the aforementioned undercuts 125 to buckle into.

[0044] In summary, in the cable hanger 100 provided in the embodiment of the present application, the structural coordination of the positioning port 122 and the sliding airbag 123 enables the sliding airbag 123 to adjust its position and be fixed in the cable installation space formed after the cover plate 121 is sealed to the mounting seat 110. Compared with the existing cable hanger 100, it can not only ensure the reliability of the hanger fixing the cable, but also can be adjusted as needed at any time. The fixing method of the limit member 1221 and the limit protrusion 1242 is easy to operate, which can improve the efficiency of cable installation and management.

[0045] At least one embodiment of the present application further provides a cable clamping device, such as Figure 4 , which is a schematic diagram of a three-dimensional structure of an embodiment of a cable clamping device, the cable clamping device includes a connecting plate 200 and two cable hangers 100 installed on the connecting plate 200, as in any of the above embodiments. In the embodiment of the cable clamping device, the connecting plate 200 exists as a component for installing the cable hanger 100, and multiple cable hangers 100 can be installed on the connecting plate 200 to meet the installation requirements in certain scenarios, such as a large number of cables that need to be classified. Figure 4 That is the simplest schematic diagram of installing the multi-cable hanger 100 on the connecting plate 200.

[0046] Preferably, when installing the multi-cable hanger 100, for the convenience of fixing cables in the early stage or maintaining and managing operations in the later stage, in the cable clamping device provided by at least one embodiment of the present application, multiple cable hangers 100 are spaced and installed on the connecting plate 200. For example, the distance between the top of each cable hanger 100 and the bottom of the adjacent cable hanger 100 is at least more than 5 cm. This can not only install more cable hangers 100 on the connecting plate 200 but also ensure that the specific operations on each cable hanger 100 are not affected.

[0047] For example, in the cable clamping device provided by at least one embodiment of the present application, as Figure 4 shown, at least one side of the connecting plate 200 is provided with a reinforcing member 210. In the embodiment of the installation form of the cable hangers 100 with a spacing formed, there may be a problem of stress concentration in the part corresponding to the spacing between the adjacent cable hangers 100 on the connecting plate 200, and even the part may be deformed or bent. A reinforcing member 210 is supplemented in this part - such as Figure 4 the form of a strip-shaped reinforcing rib in [Figure] can enhance the structural strength at this place and avoid the above problems. Of course, the reinforcing ribs can be arranged on both sides of the connecting plate 200 respectively to further strengthen the structural support ability.

[0048] For example, in the cable clamping device provided by at least one embodiment of the present application, as Figure 4 shown, one end corner of the connecting plate 200 extends to form a fixing plate 220, and a mounting member 230 for fixing the cable clamping device is arranged on the fixing plate 220. When laying cables in some grooves, the connecting plate 200 can be firmly fixed to the ground or other reliable bases through the fixing plate 220 extended by the corner and the mounting member 230 - such as rivets, thereby ensuring the basic fixing effect of the cable clamping device.

[0049] The above are only optional embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structural transformation made under the inventive concept of the present application by using the content of the specification and drawings of the present application, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
