Description

Technical Field

[0001] This application relates to the field of cable fixing technology, and in particular to a pre-embedded groove cable clamp. Background Technology

[0002] In the field of wire and cable installation and maintenance, cable clamps are indispensable as key components. They not only ensure the safe fixation of cables but also directly affect the stable operation and aesthetic appearance of electrical systems. With technological advancements and the diversification of application scenarios, the requirements for cable clamps are increasing, demanding excellent mechanical properties, weather resistance, and convenient installation. However, traditional cable clamp designs often suffer from complex installation and poor adaptability, limiting their application in complex environments. For example, in scenarios involving long-distance cable laying or parallel installation of multiple cables, existing fixed cable clamps lack the ability to flexibly adjust their position, considering both ease of installation and subsequent maintenance.

[0003] Chinese Patent Application No. 202222946251.1, entitled "A Safety Cable Fixing Clamp," discloses a clamp that can quickly fix a group of cables by setting up a locking component and an actuating component. The device uses a pressure ring to drive a drive rod to rotate, causing multiple sets of bevel gears to mesh, which in turn drives the first retaining ring on the rotating rod to rotate. Simultaneously, the second retaining ring is limited by a second connecting block, so that when the drive rod rotates, it drives multiple sets of first and second retaining rings to fix multiple groups of cables. Although this clamp can improve the efficiency and safety of installing multiple groups of cables, the fixing effect is still mechanical and rigid, unable to allow for moderate fine-tuning of the cables. This can lead to significant inconvenience in case of maintenance or installation errors. Utility Model Content

[0004] The main purpose of this application is to provide a pre-embedded cable clamp, which aims to solve the technical problem that the existing cable clamps have a mechanical installation and fixing effect and cannot be adjusted as needed.

[0005] To achieve the above objectives, this application proposes a pre-embedded cable clamp, which includes:

[0006] A slotted base and at least one clamping unit fixed on the slotted base;

[0007] The top of the two side walls of the groove base are respectively equipped with first limiting members;

[0008] Each clamping unit has a mounting hole at its bottom, through which a connector passes and engages with a second limiting member. The second limiting member is located inside the groove of the grooved base, and its two opposite edges abut against one side of the two first limiting members of the grooved base. The bottom surface of the clamping unit abuts against the other side of the two first limiting members of the grooved base.

[0009] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, each clamp unit includes a support base and a first surrounding part and a second surrounding part connected to both ends of the support base. The first surrounding part and the second surrounding part form a wrapping and fixing of the cable in a cooperating state.

[0010] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, the cross-section of the first surrounding part and the cross-section of the second surrounding part are both arc-shaped, and the arc length of the end of the first surrounding part and the second surrounding part near the support is smaller than the arc length of the end away from the support.

[0011] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, the outer side of the first enclosure portion away from the support base is provided with a locking tooth, and the inner side of the second enclosure portion away from the support base is provided with a plurality of locking slots, wherein the locking tooth engages with the plurality of locking slots to connect the first enclosure portion and the second enclosure portion.

[0012] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, a safety bolt is provided on the outer side of the first enclosure portion away from the support base, and a through-hole is also opened on the arc segment of the second enclosure portion. The safety bolt is used to pass through the through-hole and can abut against the end of the through-hole to restrict the separation of the first enclosure portion and the second enclosure portion.

[0013] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, the top of the safety bolt is provided with a buckle, and the end of the through-hole is configured to conform to the shape of the buckle so that the buckle can pass through.

[0014] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, a number of protrusions are also provided on the outer side of the edge of the second enclosure portion away from the support base.

[0015] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, the side and bottom of the support base are also provided with reinforcing members.

[0016] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, the first limiting member is configured as a fixed plate, the second limiting member is configured as a T-nut, and the connecting member is configured as a bolt.

[0017] For example, in the pre-embedded cable clamp provided in at least one embodiment of this application, the two ends of the groove base are respectively provided with mounting holes for screws or bolts to pass through to fix the position of the groove base.

[0018] Compared with existing cable clamps, the clamp of this application has at least the following beneficial effects: The pre-embedded slot cable clamp of this application, by installing the clamp unit on the slot base, allows the position of the clamp unit on the slot base to be adjusted as needed; wherein, the clamp unit, through the connection between the second limiting member and the connecting member, clamps the first limiting member between the second limiting member and the bottom of the clamp, thereby fixing the clamp unit on the slot base. This installation method is simple and quick, has a good clamping effect, and facilitates the movement of the clamp unit on the slot base, meeting the flexible adjustment requirements in cable installation and maintenance.

[0029] like Figure 1 The diagram shown is a structural schematic of an embodiment of a pre-embedded cable clamp provided in this application. In this embodiment, the pre-embedded cable clamp includes a slotted base 100 and at least one clamping unit 200 fixed on the slotted base 100. It is understood that the slotted base 100 has a certain length, allowing multiple clamping units 200 to be installed and their positions adjusted. The clamping unit 200 is used to fix one or more sets of cables. The clamping unit 200 in this embodiment does not preclude the use of clamping structures in the prior art.

[0030] Specifically, in combination Figure 1 , Figure 2 and Figure 3 The top of the two side walls of the groove base 100 are respectively provided with first limiting members 110; each clamping unit 200 has a mounting hole at the bottom so that the connector 300 passes through the mounting hole and is connected to the second limiting member 400. The second limiting member 400 is located inside the groove of the groove base 100, and its two opposite edges abut against one side of the two first limiting members 110 of the groove base 100, and the bottom surface of the clamping unit 200 abuts against the other side of the two first limiting members 110 of the groove base 100.

[0031] In this embodiment, the first limiting member 110 serves as a carrier for fixing the clamping unit 200 onto the slotted base 100. This is achieved through a clamping action by connecting with the second limiting member 400 and the clamping unit 200 via a cooperating connector 300. Figure 3 (As shown in the installation diagram), the structure of the first limiting member 110 can be varied. This embodiment uses the simplest example—the first limiting member 110 as a fixing plate—for illustration. The first limiting member 110 is a section of fixing plate, which is either integrally formed or fixed to the two side walls of the groove base 100 by welding or other means and extends along the groove diameter. The two first limiting members 110 (fixing plates) have gaps between them, allowing the connecting member 300 to pass through and connect to the second limiting member 400. Further, using a bolt as the connecting member 300 and a T-nut as the second limiting member 400 as an example, such as... Figure 2 As shown, after passing through the mounting hole at the bottom of the clamp unit 200, the bolt enters the inner side of the slotted base 100 through the gap between the two fixing plates, and is threadedly connected and fixed to the T-nut located inside the slotted base 100. The opposite edges of the T-nut abut against the bottom surface of the fixing plate (see...). Figure 3 When the bolt and nut are tightened, the bolt will also cause the bottom surface of the clamping unit 200 to abut against the top surface of the fixing plate, thereby forming a fixed shape in which the bottom surface of the clamping unit 200 and the T-nut are clamped on the fixing plate. This fixed shape allows the clamping state of a single clamping unit 200 to be released and its fixed position on the slot base 100 to be adjusted by loosening or loosening the bolt. This fixing method has both good fixing effect and is convenient and flexible to operate.

[0032] The pre-embedded cable clamp of this application, by installing the clamp unit 200 on the channel base 100, allows the position of the clamp unit 200 on the channel base 100 to be adjusted as needed. The clamp unit 200 is connected to the connector 300 via the second limiting member 400, causing the first limiting member 110 to be clamped between the second limiting member 400 and the bottom of the clamp, thus fixing the clamp unit 200 on the channel base 100. This installation method is simple and quick, provides good clamping effect, and facilitates the movement of the clamp unit 200 on the channel base 100, meeting the flexible adjustment requirements in cable installation and maintenance.

[0033] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, this application further provides a structure of clamp unit 200, each clamp unit 200 including a support base 210 and a first surrounding part 220 and a second surrounding part 230 connected to both ends of the support base 210, the first surrounding part 220 and the second surrounding part 230 forming a wrapping and fixing of the cable in a cooperating state.

[0034] See Figure 2 The clamp unit 200 provided in this embodiment consists of a U-shaped support base and two clamps installed or integrally formed at the two ends of the U-shaped support base, namely the first surrounding part 220 and the second surrounding part 230. In particular, the first surrounding part 220 and the second surrounding part 230 form a surrounding structure in the form of an arc segment (section view) in this embodiment, but possibly, they can also be set in a rectangle (section view) or other forms.

[0035] It should be noted that the clamping unit 200 in this application is connected by the deformation engagement relationship of the first surrounding part 220 and the second surrounding part 230. Therefore, the first surrounding part 220 and the second surrounding part 230 should preferably be made of a material with elastic deformation properties—such as PVC plastic—to adapt to the fastening function of the clamping unit 200 in this application.

[0036] More specifically, in this embodiment, the connector 300 passes through the support base 210 and engages with the second limiting member 400. The closing of the first surrounding portion 220 and the second surrounding portion 230 to form a surrounding structure may cause inconvenience in installing the connector 300. Therefore, furthermore, the arc length of the end of the first surrounding portion 220 and the second surrounding portion 230 closest to the support base 210 is less than the arc length of the end furthest from the support base 210. By shortening the length of the bottom of the two clamp arc segments, a notch can be reserved at the bottom after they close to form the surrounding structure, facilitating the installation of the connector 300.

[0037] As at least another embodiment of this application, in the aforementioned clamping unit 200, the outer side of the first surrounding portion 220 away from the support base 210 is provided with a locking tooth 221, and the inner side of the second surrounding portion 230 away from the support base 210 is provided with a plurality of locking slots 231. The locking tooth 221 engages with the plurality of locking slots 231 to connect the first surrounding portion 220 and the second surrounding portion 230. It should be noted that the terms "inner side" and "outer side" are distinguished relative to the openings of the first surrounding portion 220 and the second surrounding portion 230. For example, in the example where the first surrounding portion 220 and the second surrounding portion 230 are arc-shaped clamps, the side closer to the arc-shaped opening is the "inner side", and the side away from the arc-shaped opening is the outer side.

[0038] like Figure 2 As shown, the locking teeth 221 and the locking slots 231 can be configured in a common single-tooth multi-slot form, so that the enclosing space formed can be adjusted according to the locking teeth 221 and the locking slots 231 at different positions. However, this form has a possible problem: when the locking teeth 221 or the locking slots 231 age (e.g., based on the clamping unit 200 made of plastic material), the connecting force structure of the first enclosing part 220 and the second enclosing part 230 fails, and it cannot form an effective enclosing and fixing of the cable. Therefore, in an optional embodiment, a safety bolt 222 is provided on the outer side of the end of the first enclosing part 220 away from the support base 210, and a through-hole 232 is also opened on the arc segment of the second enclosing part 230. The safety bolt 222 is used to pass through the through-hole 232 and can abut against the end of the through-hole 232 to restrict the separation of the first enclosing part 220 and the second enclosing part 230.

[0039] By providing a safety bolt 222 on the outer edge of one end of the first enclosure 220 and a through-hole 232 on the second enclosure 230 for the safety bolt 222 to pass through, a locking structure can be formed between the first enclosure 220 and the second enclosure 230 on the movement trajectory. Even if the connection between the locking teeth 221 and the locking holes 231 fails and the enclosure structure formed by the first enclosure 220 and the second enclosure 230 disintegrates, the limiting effect of the safety bolt 222 and the through-hole 232 can ensure that the first enclosure 220 and the second enclosure 230 will not completely separate, resulting in the cable falling off or becoming tangled.

[0040] Furthermore, the top of the safety bolt 222 is equipped with a latch, and the end of the through-hole 232 is configured to conform to the shape of the latch for the latch to pass through. The latch design also ensures that the connection between the first enclosure 220 and the second enclosure 230 is effective, preventing it from coming out of the through-hole 232 when the enclosure structure is maintained by the safety bolt 222.

[0041] For example, in the pre-embedded slot cable clamp provided in at least one embodiment of this application, a plurality of protrusions 233 are also provided on the outer edge of the second enclosure portion 230 away from the support base 210. Providing protrusions 233 on the outer edge of the second enclosure portion 230 can facilitate the increase of friction during installation or unhooking, and make it easier to adjust the enclosure structure to fix this part.

[0042] For example, in at least one embodiment of the pre-embedded cable clamp provided in this application, the sides and bottom of the support base 210 are further provided with reinforcing members 211. The design of the reinforcing member 211 can effectively enhance the structural strength of the clamp unit 200, especially in embodiments where the clamp structure is made of plastic; the reinforcing member 211 can be configured as follows: Figure 2 The arrangement shown is achieved by either reinforcing ribs on the side of the base or by a reinforcing bracket at the bottom.

[0043] For example, such as Figure 1 As shown, in the pre-embedded cable clamp provided in at least one embodiment of this application, the two ends of the slot base 100 are respectively provided with fixing holes 500 for screws or bolts to pass through to fix the position of the slot base 100.

[0044] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
