Description

Technical Field

[0001] This utility model relates to the field of sliding contact line technology, and specifically to a hanger structure for installing sliding contact lines. Background Technology

[0002] A sliding contact line, also known as a sliding conductor, is a set of power transmission devices used to supply power to mobile equipment. A sliding contact line mainly consists of three main components: a sheath, a conductor, and a receiver, as well as some auxiliary components. The sheath is a semi-enclosed, tubular component that forms the main body of the sliding contact line, and a conductor is embedded inside it as the power supply wire.

[0003] After assembly, the sliding contact line is mainly installed at the target position using hangers. For example, Chinese patent document CN222042447U discloses a sliding contact line fixing hanger, including a base and hanger clips. There are two hanger clips, and the tops of the two hanger clips are located at the bottom of the base. During assembly, the base is first assembled in the designated position using nuts and screws. Then, the connecting blocks above the hanger clips are inserted into the positioning grooves in the base. Then, the adjusting handwheel is turned. The adjusting handwheel drives the screw to rotate through the bearing seat. The rotation of the screw drives the threaded block to move downward. The threaded block drives the roller to slide on the inner wall of the base. This can prevent the locking parts from suddenly separating during installation and improve the convenience of operation.

[0004] However, in actual use, it was found that different models of conductor rails have different numbers of conductors inside the sheath, resulting in differences in specifications. The aforementioned hanger can only be used with a single specification of conductor rail, thus limiting its applicability and making it less flexible in use overall. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hanger structure for installing sliding contact lines, which can be adapted to sliding contact lines of different specifications, expand the scope of application, and improve the flexibility of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hanger structure for installing a sliding contact line, including a base plate, on which two symmetrically arranged locking blocks are provided, forming a space for installing a protective sleeve between the two locking blocks. The two locking blocks can move towards each other or away from each other to adjust the size of the space to accommodate protective sleeves of different specifications. The base plate is provided with a slide rail, and the bottom of the locking blocks is provided with a slider. The slider is coupled to the slide rail and can form a sliding fit between the two to ensure the stability of the locking blocks when they move.

[0007] The present invention is further configured such that: a clearance groove is provided on the base plate, the slider is symmetrically arranged at the bottom of the block, and a connecting block is provided at the center of the clearance groove.

[0008] The present invention is further configured such that: the connecting block is provided with two cross-arranged balance bars, the balance bars are rotatably connected to the connecting block, the end of the balance bar is provided with a protruding guide rod, the locking block is provided with a through guide waist hole, and one end of the guide rod extends to the guide waist hole.

[0009] The present invention is further configured such that: a tension spring is provided in the relief groove, a protruding connecting protrusion is provided at the bottom of the card block, and the two ends of the tension spring are respectively fixed to the connecting protrusions on both sides.

[0010] The present invention is further configured such that: the connecting block is provided with a through guide hole, through which the tension spring passes.

[0011] The present invention is further configured such that: a connecting post is provided at the bottom of the base plate, and a snap-fit ​​bramble is provided on the outer periphery of the connecting post.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because two symmetrically arranged locking blocks are set on the base plate, a space for installing the protective sleeve is formed between the two locking blocks. The two locking blocks can move towards each other or away from each other to adjust the size of the space, so as to accommodate protective sleeves of different specifications, expand the scope of application, and improve the flexibility of use.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, this utility model discloses a hanger structure for installing a sliding contact line, including a base plate 1. Two symmetrically arranged locking blocks 2 are provided on the base plate 1, forming a space 3 for installing a protective sleeve between the two locking blocks 2. The two locking blocks 2 can move towards each other or away from each other to adjust the size of the space 3, thus adapting to different specifications of protective sleeves, expanding the scope of application, and improving the flexibility of use. A slide rail 4 is provided on the base plate 1, which is fixed to the base plate 1 with screws. An integrally injection-molded slider 5 is provided at the bottom of the locking block 2, coupling to the slide rail 4 and forming a sliding engagement between them. This guides the movement of the locking block 2 during its movement, ensuring the stability of the locking block 2 during movement.

[0020] In this embodiment, a clearance groove 6 is provided on the base plate 1. By setting the clearance groove 6, more space 3 can be provided for hand movement during assembly, so as to facilitate operation and improve the convenience of assembly. In addition, the slider 5 is symmetrically arranged at the bottom of the block 2. Thus, by installing multiple slide rails 4, the stability of the block 2 when moving can be further improved.

[0021] In addition, a connecting block 7 is provided in the center of the relief groove 6. The connecting block 7 is integrally injection molded with the base plate 1. A tension spring 9 is provided in the relief groove 6. The bottom of the locking block 2 is provided with a protruding connecting protrusion 22. The two ends of the tension spring 9 are respectively fixed to the connecting protrusions 22 on both sides. Therefore, when the sheath is installed in the space 3, the elastic force generated by the tension spring 9 can drive the locking block 2 to press against the sheath, thereby improving the stability of the sheath installation. Furthermore, by utilizing the telescopic characteristic of the tension spring 9, the normal movement of the locking blocks 2 on both sides is not affected, thus enabling the installation of sheaths of different specifications.

[0022] Furthermore, a through guide hole is provided on the connecting block 7, through which the tension spring 9 passes. By setting the guide hole, the tension spring 9 can be guided when it is stretched, reducing the offset of the tension spring 9 and ensuring that the tension spring 9 can be on the same horizontal line when it is extended and retracted, so that the force applied by the tension spring 9 to the two side blocks 2 is more uniform.

[0023] In this embodiment, two cross-arranged balance bars 8 are provided on the connecting block 7. The center of the balance bar 8 is rotatably connected to the connecting block 7 through a pin. The end of the balance bar 8 is provided with a protruding guide rod 81. The locking block 2 is provided with a through guide waist hole 21. One end of the guide rod 81 extends to the guide waist hole 21. When the locking blocks 2 on both sides move, the balance bar 8 can be driven to rotate accordingly through the contact between the peripheral wall of the guide rod 81 and the peripheral wall of the guide waist hole 21. Thus, under the action of the two balance bars 8, the movement of the locking blocks 2 on both sides can be kept synchronous. Therefore, when adjusting the size of the space 3, the center of the space 3 can remain unchanged.

[0024] In this embodiment, a connecting post 10 is provided at the bottom of the base plate 1, and a snap-fit ​​rib 11 is provided on the outer periphery of the connecting post 10. When fixing the hanger, by pressing the connecting post 10 into the corresponding connecting hole, the snap-fit ​​rib 11 can be deformed under pressure, thereby tightly abutting between the connecting post 10 and the connecting hole. The friction generated can fix the base plate 1, which is faster and more convenient than the traditional locking parts (such as bolts and nuts) for fixing.

[0025] The specific implementation process of this plan is as follows:

[0026] First, press the connecting post 10 into the connecting hole to fix the base plate 1. Then, push the sheath into the space 3 formed between the two side locking blocks 2. During the pushing process, the tension spring 9 can be stretched to both sides, so that the locking block 2 can be pressed against the sheath. The hook on the locking block 2 can be pressed into the corresponding groove on the sheath to achieve stable fixation of the sheath.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
