Description

Technical Field

[0001] The utility model relates to the technical field of mounting fixtures, in particular to a mounting fixture for a truss self-contained power supply lamp. Background Art

[0002] As we all know, lamps are the most common photography equipment in daily life. In some specific places, such as stages and parties, trusses will be erected, and then lamps will be installed on the trusses to illuminate the venue below. When lamps are installed on trusses, corresponding clamps will be required.

[0003] At present, the existing lamps suitable for trusses are divided into two types according to the power supply: one is a wired power supply lamp, which mainly has a guaranteed power supply time. However, for temporary trusses, this kind of wired lamp, when installed, must not only follow the lamps, but also reasonably lay out the wiring, the operation is very troublesome. When there are too many lamps, it will cause a messy cable line, and it will be very troublesome when dismantling the truss; the other is a self-contained power supply lamp, that is, the power cord is eliminated and it is directly equipped with a battery. This kind of lamp is very convenient to install on the truss, especially for the use on temporary trusses. However, during installation, existing installation fixtures are basically installed by bolts, gaskets and installation holes on the truss. Although it can ensure stability after installation, the self-powered lamps have their own batteries, which will increase the overall weight of the lamps. When using existing installation fixtures to install self-powered lamps, one hand is required to hold the lamp until it is locked. On the one hand, only one hand can complete the tightening operation, which is not convenient for installation. On the other hand, because the hand holds the lamp for a long time and keeps the same action, the installation is very tiring. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a mounting fixture for a truss self-contained power supply lamp.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An installation fixture for a truss self-powered lamp, comprising at least two lugs, at least two bolts and a receiving groove provided on the lamp. Each of the lugs is in a "several" shape, with a first hook portion bent outward and a second hook portion bent inward respectively provided at both ends of the lug. A threaded through hole is provided in the middle of the lug. The bolt is screwed into the threaded through hole and a top cap is sleeved on the top end. The receiving groove is provided at the connection between the main body and the lamp head of the lamp. An accommodating groove for accommodating a pipe is provided at the bottom of the receiving groove and at the corner. A receiving platform is provided at one place of the upper slot opening of the receiving groove. Third hook portions equal in number to the lugs are provided at the edge ends of the receiving platform. A receiving groove surface is provided at the bottom of the receiving groove. Fourth hook portions equal in number to the lugs are provided at the edge end of the receiving groove surface far from the accommodating groove. An avoidance position is provided between adjacent third hook portions and fourth hook portions, and the gap of the avoidance position is larger than the width of the lug.

[0007] Preferably, a limiting groove is provided on the inner end surface of the lug at the position of the threaded through hole, and a nut is placed in the limiting groove. Among them, the width of the limiting groove is larger than the minimum diameter of the nut and smaller than the maximum diameter of the nut, so that the nut can be placed in the limiting groove but cannot rotate.

[0008] Preferably, an arc surface for abutting against the surface of the pipe is provided on the inner end surface of the lug, and the shape of the arc surface corresponds to that of the pipe.

[0009] Preferably, at least one corner portion is provided at both ends of the lug.

[0010] Preferably, at least one strip-shaped through groove is provided at the position of the receiving platform at the slot opening of the receiving groove.

[0011] Preferably, the top cap is made of soft rubber material.

[0012] Preferably, the bolt is an internal hexagonal bolt, and anti-slip corrugations are provided on the periphery of the head of the bolt.

[0013] Due to the adoption of the above scheme, the present utility model forms pre-installation by the first hook portion and the second hook portion provided on the lug and the third hook portion and the fourth hook portion. After being properly aligned with the pipe, it can play a role in preliminary fixation, eliminating the need to hold the lamp by hand, thus liberating both hands and allowing both hands to focus on the final locking of the lug. At the same time, the final locking of the lug only requires screwing a single bolt, so that the other end of the bolt gradually presses against the pipe. Under the action of the reaction force, the overlap between the first hook portion, the second hook portion, the third hook portion and the fourth hook portion will become tighter and tighter until the lug can no longer move, and the overall locking operation is very simple.

[0023] As Figures 1 to 6 shown, an installation fixture for a truss self-powered lamp provided in this embodiment includes at least two tabs 1, at least two bolts 2, and a receiving groove 3 provided on the lamp 101. Each of the tabs 1 is in a "C" shape. At both ends of the tab 1, a first hook portion 11 bent outward and a second hook portion 12 bent inward are respectively provided. A threaded through hole 13 is provided in the middle of the tab 1. The bolt 2 is screwed into the threaded through hole 13 and a top cap 21 is sleeved on the top end. The receiving groove 3 is provided at the junction of the main body and the lamp head of the lamp. At the bottom of the receiving groove 3 and at the corner, a placement groove 31 for receiving a pipe 100 (generally a conventional round pipe on the truss) is provided. At one place of the upper slot opening of the placement groove 31, a receiving platform 32 is provided. At the edge of the receiving platform 32, third hook portions 33 equal in number to the tabs 1 are provided. A receiving groove surface 34 is provided at the bottom of the receiving groove 3. At the edge of the receiving groove surface 34 away from the placement groove 31, fourth hook portions 35 equal in number to the tabs 1 are provided. A clearance position 36 is provided between adjacent third hook portions 33 and fourth hook portions 35, and the gap of the clearance position 36 is greater than the width of the tab 1.

[0024] In this embodiment, the first hook portion 11 and the second hook portion 12 provided on the tab 1 form a pre-installation with the third hook portion 33 and the fourth hook portion 35. After being properly aligned with the pipe 100, it can play a role in preliminary stabilization, eliminating the need to hold the lamp by hand, thus freeing both hands to focus on the final locking of the tab 1. At the same time, the final locking of the tab 1 only requires tightening a single bolt 2, so that the other end of the bolt 2 gradually presses against the pipe 100. Under the action of the reaction force, the overlap between the first hook portion 11, the second hook portion 12, the third hook portion 33, and the fourth hook portion 35 will become tighter and tighter until the tab 1 can no longer move, and the overall locking operation is very simple.

[0025] When assembling this embodiment, first hold the lamp, then fit the pipe 100 with the mounting groove 31, and keep the lamp and the pipe 100 from being offset, select a suitable number of straps 1 (generally at least two), and put the straps 1 in from the avoidance position 36. At this time, the first hook portion 11 of the strap 1 is placed in the receiving groove surface 34, and the second hook portion 12 of the strap 1 is placed on the receiving platform 32. Then move the strap 1 horizontally until the first hook portion 11 on the strap 1 enters the fourth hook portion 35 and the second hook portion 12 enters the third hook portion 33, keeping the hook portions flush. Then, there is no need to hold the lamp anymore, and the connection between the lamp and the pipe 100 can be maintained. However, in order to prevent the hooks from staggering after the flap 1 moves, the bolts 2 need to be tightened at last, so that the bolts 2 are gradually screwed in, so that the top pressure between the top cap 21 and the pipe 100 becomes tighter and tighter, and under the reaction force, the flap 1 will move relatively backward, so that the overlap between the first hook 11 and the fourth hook 35, the second hook 12 and the third hook 33 will be very tight, so that the flap 1 cannot move, thereby ensuring the stability between the lamp and the pipe 100. When tightening the bolts 2, if necessary, the lamp can also be gently supported, so that the tightening effect will be better. When disassembly is required, just unscrew the bolts 2, and stagger the flap 1 to the avoidance position 36, and then the lamp can be removed, and the overall operation is very convenient.

[0026] Furthermore, because the thickness of the strap 1 is relatively thin (because it needs to have a certain degree of toughness and leave space for the pipe to be placed, it is designed to be thinner), if the bolt 2 is tightened by relying solely on the threads of the threaded through hole 13, it will easily become loose or not be tightened firmly. Therefore, a limiting groove 14 is provided on the inner end surface of the strap 1 of this embodiment and located at the threaded through hole 13, and a nut 15 is placed in the limiting groove 14, wherein the width of the limiting groove 14 is greater than the minimum diameter of the nut 15 and smaller than the maximum diameter of the nut 15, so that the nut 15 can be placed in the limiting groove 14 but cannot be rotated, thereby strengthening the threaded connection of the bolt 2 and stabilizing the bolt 2.

[0027] Furthermore, in order to better meet the requirements for the installation of the pipe 100, the inner end surface of the strap 1 of this embodiment is provided with a curved surface 16 for abutting against the surface of the pipe 100. The shape of the curved surface 16 corresponds to the pipe 100, so that when the bolt 2 is not tightened, it can play a role in limiting the installation of the pipe 100 and prevent the pipe 100 from moving.

[0028] Furthermore, in order to improve the toughness of the strap 1, at least one corner portion 17 is provided at both ends of the strap 1 of this embodiment. At least one linear through groove 37 is provided at the notch of the containing groove 3 located at the receiving platform 32, so that a space for slight deformation is provided at the notch of the containing groove 3 during assembly.

[0029] Furthermore, in order to reduce damage to the pipe 100, the top cap 21 of this embodiment is made of soft rubber. Moreover, the bolt 2 of this embodiment is a hexagon socket bolt, and an anti-slip corrugation 22 is arranged on the periphery of the head of the bolt 2, so that when the bolt 2 is tightened at the beginning, it can be tightened by hand until it cannot be tightened by hand, and then tightened with a tool, which facilitates and accelerates the installation of the bolt 2.

[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
