Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing bracket technology, and in particular to a shock-absorbing spring bracket. Background Technology

[0002] In power transmission and distribution systems, busbar trunking, as a highly efficient power transmission device, is widely used in various buildings, industrial plants, and other locations. Busbar trunking can carry large currents and offers advantages such as stable transmission and convenient installation and maintenance. However, in actual use, busbar trunking is affected by various external forces, such as building vibrations or vibrations generated by equipment operation. If these vibrations are not effectively managed, they may cause loosening of internal connections within the busbar trunking, leading to safety hazards. Vibration-damping spring supports, as a commonly used vibration damping device, are applied in multiple fields.

[0003] When shock-absorbing spring brackets are used in conjunction with busbar trunking, depending on the different installation paths of the busbar trunking, there are busbar trunking installed vertically through the carrier and busbar trunking installed horizontally at the same height on the carrier. In related technologies, shock-absorbing spring brackets cannot be applied to the installation of busbar trunking in different installation directions, and their applicability is poor. Utility Model Content

[0004] In view of this, the present invention aims to provide a shock-absorbing spring bracket to improve the applicability of the shock-absorbing spring bracket.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A shock-absorbing spring bracket for mounting a busbar trunking system on a carrier, the shock-absorbing spring bracket comprising:

[0007] A connecting rod having a mating surface that abuts against the busbar groove along the width direction of the busbar groove; the connecting rod having a first through hole perpendicular to the mating surface, and a second through hole extending along the extension direction of the busbar groove and perpendicular to the first through hole;

[0008] The locking part is engaged with the busbar groove to form a detachable connection between the busbar groove and the connecting rod;

[0009] A shock-absorbing part is connected to the carrier. The shock-absorbing part includes a guide rod, which is slidably inserted into the first through hole or the second through hole, forming a connection between the guide rod and the connecting rod, so that the connecting rod can undergo relative displacement with respect to the carrier.

[0010] Furthermore, the shock-absorbing part includes: an adjusting rod, which is parallel to the connecting rod and fixedly connected perpendicularly to the guide rod; a first elastic body, which is telescopically disposed between the adjusting rod and the connecting rod; and a base, on which the adjusting rod is connected so that the adjusting rod can slide along the width direction of the busbar groove.

[0011] Furthermore, the base includes: a seat body, the seat body being distributed along the width direction of the busbar groove, the seat body having a cavity; a sliding groove communicating with the cavity being formed along the length direction of the seat body; an adjusting rod being located within the cavity, the guide rod passing through the sliding groove and being slidable along the opening direction of the sliding groove; and a second elastic body being provided at both ends of the adjusting rod, the second elastic body extending and contracting as the guide rod slides within the sliding groove.

[0012] Furthermore, two guide rods are provided, and the two guide rods are located on both sides of the busbar groove.

[0013] Furthermore, the first elastic body is sleeved on the guide rod; the first elastic body is selected as a spring.

[0014] Furthermore, fixing holes are formed at both ends of the seat body along the length direction of the seat body.

[0015] Furthermore, a slot is provided along the length of the busbar groove; the locking part includes teeth that engage in the slot, a locking piece that is fixed to the teeth and extends close to the busbar groove to the connecting rod, and a locking member that passes through and connects the locking piece and the connecting rod.

[0016] Furthermore, the locking element includes a bolt and a nut, the nut being located on the side of the connecting rod opposite to the busbar groove.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The shock-absorbing spring bracket of this utility model, by setting a locking part, enables the connecting rod to be detachably connected to the busbar trough. When the busbar trough is installed vertically, the guide rod is inserted into the second through hole, and the shock-absorbing part is fixed to the carrier. When the busbar trough is installed horizontally, the abutting surface of the connecting rod is kept pressed against the busbar trough, and the guide rod is inserted into the first through hole. The shock-absorbing spring bracket configured as described above helps ensure the connection stability of the busbar trough and reduces safety hazards when relative vibration displacement occurs between the busbar trough and the carrier. Furthermore, this shock-absorbing spring bracket is applicable to different installation directions of the busbar trough and has good applicability.

[0019] Meanwhile, when the guide rod is inserted into the second through hole, i.e., when the busbar is installed vertically, the connecting rod can move relative to the carrier along the length of the busbar, which helps ensure the safety of the busbar. Simultaneously, the base, as described above, allows the busbar to move relative to the carrier along its width, further contributing to its safety. When the guide rod is inserted into the first through hole, i.e., when the busbar is installed horizontally, the connecting rod can move relative to the carrier along the width of the busbar and also along its thickness, thus improving the connection stability between the busbars.

[0020] Secondly, by designing a base with a cavity and a sliding groove, when the adjusting rod slides along the length of the base, the second elastic bodies at both ends of the adjusting rod undergo tensile or compressive changes. This satisfies the requirement for relative displacement between the busbar and the carrier.

[0021] Furthermore, by fitting the first elastic body onto the guide rod, the first elastic body can be easily stretched or compressed along a preset path, that is, along the length of the guide rod, which helps to improve the shock absorption stability of the shock-absorbing spring bracket.

[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] This embodiment relates to a shock-absorbing spring bracket to improve the applicability of the shock-absorbing spring bracket.

[0040] In terms of overall structure, such as Figures 1 to 5As shown, the spring damping bracket is used to install the busbar trough 4 on the carrier 5. The damping spring bracket includes a connecting rod 1, a clamping part 2, and a damping part 3. The connecting rod 1 has a pressing surface 1a, which abuts against the busbar trough 4 along the width direction of the busbar trough 4. The connecting rod 1 has a first through hole 1b perpendicular to the pressing surface 1a and a second through hole 1c extending along the extension direction of the busbar trough 4 and perpendicular to the first through hole 1b. The clamping part 2 is engaged with the busbar trough 4 to form a detachable connection between the busbar trough 4 and the connecting rod 1. The damping part 3 is connected to the carrier 5 and includes a guide rod 301. The guide rod 301 is slidably inserted into the first through hole 1b or the second through hole 1c to form a connection between the guide rod 301 and the connecting rod 1, so that the connecting rod 1 can undergo relative displacement with the carrier 5.

[0041] By setting the clamping part 2, the connecting rod 1 can be detachably connected to the busbar trough 4. When the busbar trough 4 is installed vertically, the guide rod 301 is inserted into the second through hole 1c, and the shock-absorbing part 3 is fixed to the carrier 5. When the busbar trough 4 is installed horizontally, the abutting surface of the connecting rod 1 is kept pressed against the busbar trough 4, and the guide rod 301 is inserted into the first through hole 1b. The shock-absorbing spring bracket set as described above helps to ensure the connection stability of the busbar trough 4 and reduce safety hazards when the busbar trough 4 and the carrier 5 experience relative vibration displacement. At the same time, the shock-absorbing spring bracket can be used in different installation directions of the busbar trough 4 and has good applicability.

[0042] Based on the above overview, as an optional implementation method, specifically, in implementation, such as... Figures 1 to 3 As shown, the connecting rod 1 is designed as a rectangular column structure. This design makes it less likely for the connecting rod 1 to rotate along its own axis after the mating surface 1a is pressed against the busbar groove 4, which helps to improve the connection stability between the connecting rod 1 and the busbar groove 4. Based on the rectangular column shape of the connecting rod 1, a first through hole 1b and a second through hole 1c can be provided to connect them. This design reduces the length required to open the first through hole 1b and the second through hole 1c on the connecting rod 1, thereby helping to reduce the space occupied by the shock-absorbing spring bracket after installation.

[0043] Specifically, in order to effectively reduce vibration in both vertical and horizontal installations of the busbar 4, as an optional implementation of the vibration damping unit 3, in practice, such as... Figure 2 and Figure 3 As shown, the shock-absorbing part 3 includes an adjusting rod 302, a first elastic body 303, and a base 304; the adjusting rod 302 is parallel to the connecting rod 1 and is fixedly connected to the guide rod 301 perpendicularly; the first elastic body 303 is telescopically disposed between the adjusting rod 302 and the connecting rod 1; the adjusting rod 302 is connected to the base 304 so that the adjusting rod 302 can slide along the width direction of the busbar groove 4.

[0044] As described above, when the guide rod 301 is inserted into the second through hole 1c, i.e., when the busbar 4 is installed vertically, the connecting rod 1 can move relative to the carrier 5 along the length of the busbar 4, thus helping to ensure the safety of the busbar 4. Simultaneously, the base 304 described above allows the busbar 4 to move relative to the carrier 5 along the width of the busbar 4, further contributing to the safety of the busbar 4. When the guide rod 301 is inserted into the first through hole 1b, i.e., when the busbar 4 is installed horizontally, the connecting rod 1 can move relative to the carrier 5 along the width of the busbar 4 and also relative to the carrier 5 along the thickness of the busbar 4, thus improving the connection stability between the busbars 4.

[0045] Based on the above, as an optional implementation of the base 304, specifically, in implementation, such as Figure 2 and Figure 3 As shown, the base 304 includes a seat body 3041 and a second elastic body 3042. The seat body 3041 is distributed along the width direction of the busbar groove 4. The seat body 3041 has a cavity 3041a and a sliding groove 3041b communicating with the cavity 3041a is opened along the length direction of the seat body 3041. The adjusting rod 302 is located in the cavity 3041a, and the guide rod 301 passes through the sliding groove 3041b and can slide along the opening direction of the sliding groove 3041b. The second elastic body 3042 is located at both ends of the adjusting rod 302 and the second elastic body 3042 extends and retracts as the guide rod 301 slides in the sliding groove 3041b.

[0046] By configuring the base 304 with a cavity 3041a and a sliding groove 3041b, when the adjusting rod 302 slides along the length of the base 3041, the second elastic bodies 3042 located at both ends of the adjusting rod 302 undergo stretching or compression changes. This satisfies the requirement for relative displacement between the busbar 4 and the carrier 5.

[0047] Optionally, as a specific arrangement of the guide rod 301, two guide rods 301 may be provided, with the two guide rods 301 located on both sides of the busbar trough 4, that is, the two guide rods 301 are respectively connected to both ends of the connecting rod 1 along its length. With this arrangement, when the busbar trough 4 is installed laterally and displacement occurs along the thickness direction of the busbar trough 4 with the carrier 5, the guide rods 301 will not abut against the busbar trough 4, allowing for a larger displacement space between the busbar trough 4 and the carrier 5.

[0048] To facilitate the connection between the base 3041 and the carrier 5, fixing holes 6 are formed at both ends of the base 3041 along its length. When connecting the base 3041 and the carrier 5, screws pre-embedded in the carrier 5 can be passed through the fixing holes 6 to fix the base 3041 and the carrier 5; or expansion screws can be used to fix the base 3041 to the carrier 5 by passing through the fixing holes 6.

[0049] As an optional implementation of the first elastic body 303 and the second elastic body 3042, specifically, as Figure 2 and Figure 3 As shown, in this embodiment, both the first elastic body 303 and the second elastic body 3042 are springs. This arrangement gives the first elastic body 303 and the second elastic body 3042 good fatigue resistance. Based on the above arrangement, the first elastic body 303 is sleeved on the guide rod 301. By sleeved on the guide rod 301, the first elastic body 303 can be easily stretched or compressed along a predetermined path, that is, along the length direction of the guide rod 301, which helps to improve the shock absorption stability of the shock-absorbing spring bracket.

[0050] As an optional implementation of the locking part 2, specifically, in implementation, such as Figure 1 and Figure 3 As shown, a slot 4a is provided along the length of the busbar 4; the clamping part 2 includes teeth 201 that engage in the slot 4a, a clamping piece 202 that fixes the teeth 201 and extends close to the busbar 4 to the connecting rod 1, and a locking member 203 that passes through and connects the clamping piece 202 and the connecting rod 1. In this embodiment, the locking member 203 includes a bolt 2031 and a nut 2032, with the nut 2032 located on the side of the connecting rod 1 away from the busbar 4.

[0051] During installation, first engage the tooth 201 in the slot 4a, and then use the locking element 203 to connect the locking piece 202 to the connecting rod 1, thus completing the detachable connection between the connecting rod 1 and the busbar trough 4. When using this shock-absorbing spring bracket to connect the busbar trough 4 to the carrier 5, the connecting rod 1 can be fixed to the busbar trough 4 first without being affected by the shock-absorbing part 3, which facilitates the construction operation.

[0052] The shock-absorbing spring bracket described in this application, by providing a clamping part 2, allows for the detachable connection of the connecting rod 1 to the busbar 4. When the busbar 4 is installed vertically, the guide rod 301 is inserted into the second through hole 1c, and the shock-absorbing part 3 is fixed to the carrier 5. When the busbar 4 is installed horizontally, the contact surface of the connecting rod 1 is kept pressed against the busbar 4, and the guide rod 301 is inserted into the first through hole 1b. With the shock-absorbing spring bracket configured as described above, when the busbar 4 and the carrier 5 experience relative vibration displacement, it helps ensure the connection stability of the busbar 4 and reduces safety hazards. Furthermore, this shock-absorbing spring bracket is applicable to different installation directions of the busbar 4 and has good applicability.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
