Description

Technical Field

[0001] The utility model relates to a bracket and also relates to a power line device which uses the bracket to support a power line arranged between two relatively movable devices. Background Art

[0002] A power cord is set between the fixed device and the movable device (or between two relatively movable devices), and the length of the power cord must first meet the length requirement of the movable device moving from the starting position (the moving distance relative to the fixed device is zero) to the farthest position (the moving distance relative to the fixed device is the farthest distance) relative to the fixed device; if an ordinary power cord is used, when the movable device moves from the farthest position back to the starting position, the power cord will sag due to its own weight, and the sagged power cord may be hooked and entangled with other objects. On the one hand, it may interfere with the movable device and affect the normal movement of the movable device. On the other hand, when the power cord is hooked and entangled with other objects, the movable device is forced to move, which may cause damage to the power cord or a weak structure hooked and entangled with the power cord, posing a safety hazard in use.

[0003] In order to overcome the defect of the hanging power cord connected between the fixed device and the mobile device, U.S. Patent US10003159 discloses an enclosed power outlet (Enclosed Power Outlet), which adopts a flat bicycle chain structure or a flat connecting rod structure, and utilizes the chain rigidity of the bicycle chain when it is flat and the rotation of the chain links to achieve the chain swing, so as to support the power cord and prevent the power cord from hanging, and utilizes the rigidity of the connecting rod structure and the rotation between the connecting rods to achieve the connecting rod swing, so as to support the power cord and prevent it from hanging.

[0004] However, the above-mentioned prior art has the following defects: first, in the deployment and retraction actions of the bicycle chain structure or the connecting rod structure itself, there is a defect of low movement stability. When the mobile device for installing the power cord has a sliding tendency relative to the fixing device, the bicycle chain structure or the connecting rod structure cannot play a role in stabilizing the mobile device; secondly, the existing bicycle chain structure and connecting rod structure adopt a double-layer structure for the fixing structure of the power cord, and the power cord is fixed in the middle, which makes the bicycle chain structure and the connecting rod structure complicated and the manufacturing cost high.

Although the specification discloses typical embodiments, there may be other embodiments that change the embodiments of the specification without departing from the spirit and scope of the utility model. The following detailed description does not limit the utility model, and the protection scope of the utility model is defined by the claims and their equivalent technical solutions.

[0033] like Figures 1 to 3 As shown, the bracket 100 of the present invention includes a scissor mechanism 10 and a box body 20 .

[0034] The scissor mechanism 10 includes a first guide rod 11, a second guide rod 16, a first fork rod group and a second fork rod group. The first guide rod 11 and the second guide rod 16 are respectively provided with guide grooves (such as Figure 6 The first guide rod 11 is provided with a guide groove 112, and the number of fork rods in the first fork rod group and the second fork rod group is equal. In this embodiment, the number of fork rods in the first fork rod group and the second fork rod group are both two; in other embodiments, the number of fork rods in the first fork rod group and the second fork rod group can be one, three or more, and the purpose of the present invention can be achieved.

[0035] When the number of fork rods in the first fork rod group and the second fork rod group is more than two, the fork rods are hinged end to end in sequence. Figure 1 , Figure 3 As shown, the fork rods 13 and 14 of the first fork rod group are hinged end to end in sequence, and the fork rods 12 and 15 of the second fork rod group are hinged end to end in sequence.

[0036] like Figure 1As shown, the head and tail of the first fork rod group are respectively hinged to the end of the first guide rod 11 and the end of the second guide rod 16. The head and tail of the second fork rod group are respectively slidably connected to the guide groove of the first guide rod 11 and the guide groove of the second guide rod 16.

[0037] The forks 13 and 14 of the first fork group are hinged at the intersection with the corresponding forks 12 and 15 of the second fork group located below them, ensuring that the first guide rod 11, the second guide rod 16, the first fork group and the second fork group of the bracket 100 can be unfolded and folded.

[0038] The box body 20 is disposed at the lower side of the second guide rod 16 and is used to install electrical devices, such as an electrical power supply, a controller, and the like.

[0039] A power cord fixing device is provided on the forks 13 and 14 of the first fork rod group along the length direction of the forks. In this embodiment, the power cord fixing device is a through hole 34 correspondingly provided on both sides of the fork rod of the first fork rod group, so that a fixing member can pass through the through hole 34 to fix the power cord on the fork rod of the first fork rod group.

[0040] In other embodiments, the power cord fixing device may adopt grooves correspondingly arranged on both sides of the fork rods of the first fork rod group, so that the fixing member can fix the power cord on the fork rods of the first fork rod group through the grooves.

The folded edges 131, 141 also guide the power cord to prevent the power cord from twisting irregularly.

[0044] like Figure 3 , Figure 4 As shown, in order to guide the end of the power cord fixed on the bracket, a power cord guide mechanism is provided at the end where the first guide rod 11, the second guide rod 16 and the first fork rod group are connected end to end. In this embodiment, the power cord guide mechanism adopts a guide hole 111 provided on the bent edge of the end of the first guide rod 11, and a guide hole is provided on the bent edge at the end of the first guide rod 16.

[0045] In other embodiments, the power cord guiding mechanism may adopt a guiding groove provided on the bent edge of the end of the guide rod, which can also achieve the purpose of the invention.

[0052] The power cord 210 is unfolded and folded along with the bracket 100, so as to meet the requirement of the change of the moving distance of the electrical appliance along with the movement of the installation base.

[0053] In this embodiment, one end of the power cord 210 is connected to a plug. In other embodiments, as needed, one end of the power cord 210 is connected to a plug and the other end is connected to an electrical power source or controller installed in the box body 20. In other embodiments, one end of the power cord 210 is connected to an electrical power source or controller installed in the box body 20, and the other end is directly connected to a power supply.
