Description

The quick assembling mechanism of light fixture and junction block

Technical field

The utility model relates to a kind of assembling mechanism, the quick assembling mechanism of particularly a kind of light fixture and junction block.

Background technology

General lamp stand and junction block all be by screw with lamp stand mutually interlocking establish fixing, the user is when assembling, must establish by the tool using lock, lamp stand and junction block can be fixed, cause the user to assemble inconvenience, in addition, because promptly electric wire having been worn also wiring before factory's shipment finishes, for reducing the volume of timber, mostly lamp stand and lamp socket are separated, however the wiring state that electric wire is arranged in lamp stand and the junction block still exists, when user's desire is assembled, must be on junction block with the lamp stand interlocking, then often when lock is established, very easily destroy the insulating barrier of electric wire, cause copper cash exposed and do not know, so that the assembling back produces and should touch lamp outer casing by exposed copper cash, and causes the contingency of electric leakage; For preventing that this contingency from taking place, this lamp stand and junction block are simply promptly assembled before dispatching from the factory and are finished, and so, can prevent that contingency from taking place, yet have increased the volume of timber and cost of transportation in its carrying relatively.

Summary of the invention

The purpose of this utility model provides a kind of be convenient to assemble and avoid the injuring light fixture of electric wire and the quick assembling mechanism of junction block.

The utility model is to realize like this, the quick assembling mechanism of a kind of light fixture and junction block, the junction block that is used for desk lamp, pendent lamp, wall lamp or floor lamp combines with lamp stand, and more than one at least fixing hole is set on the described junction block, fixes for more than one lamp stand; Comprise: a location sleeve, in axially running through a polygonal endoporus, be equipped with thread and, offer an accommodating chamber outside it in its sidewall appropriate location, for torque spring ornaments,, be arranged with a holding tank again in the end face of abutment sleeve, swing in for a rotary block; Two retainer rings are established toward internal lock by the front and back of the external screw teeth of deciding outer sleeve respectively, and abutment sleeve are fixed on the fixing hole of junction block, simultaneously torque spring and rotary block are limited in respectively in accommodating chamber and the holding tank; One rotary block is established a polygonal hole on it, and corresponding with the polygonal endoporus of abutment sleeve, and establishes a pushing block at the side of rotary block, and when making rotary block swing in the holding tank of abutment sleeve, this pushing block just can lean for the torque spring of accommodating chamber; This rotary block can reverse in the holding tank of the next sleeve, it reverses the limit and just is polygonal endoporus in an overlapping the corresponding state of this polygonal hole with abutment sleeve, and the involution original position of rotary block, Qi Jiao hole and aforementioned polygonal endoporus are non-overlapped crossing condition mutually; One lamp stand, its front end are established a polygonal bar, and corresponding with the polygonal endoporus of the polygonal hole of rotary block and abutment sleeve, and establish a draw-in groove between polygonal bar and lamp stand are by ring, and in many bars central shaft to running through electric wire perforation, and be connected with lamp stand.

Therefore, the rotation of mat rotary block and involution with the strong fix of blocking lamp stand and junction block, are convenient to user's assembling, and can be avoided injuring electric wire; Separable disassembling when carrying is to reduce its carrying volume of timber and to reduce cost.

Below in conjunction with accompanying drawing the utility model is elaborated.

The specific embodiment

At first referring to Fig. 1, Fig. 2 and Fig. 3-A, junction block 1 can be the junction block that pendent lamp, wall lamp, desk lamp or floor lamp are suitable for, and can establish at least one fixing hole 11 on it, and is fixing for a location sleeve 2; And this abutment sleeve 2 axially run through a polygonal endoporus 21, it is outer to be equipped with external screw teeth 22, and in its sidewall appropriate location, offer an accommodating chamber 23, for a torque spring 24 ornaments, again in the end face of abutment sleeve 2, be arranged with a holding tank 25, insert for a rotary block 3; Establish a polygonal hole 31 on this rotation thermal source piece 3, and it is corresponding with the polygonal endoporus 21 of abutment sleeve 2, and establish a pushing block 32 at the side of rotary block 3, when making rotary block 3 insert the holding tank 25 of abutment sleeve 2, this pushing block 32 can lean for the torque spring 24 of accommodating chamber 23 just the opposite; Or on the pushing block 32 of rotary block 3, establish an axis hole 321, directly insert by torque spring 24.Referring to Fig. 3-A and Fig. 4, the polygonal hole 31 of this rotary block 3 is non-overlapped crossing condition with the polygonal endoporus 21 of abutment sleeve 2; When abutment sleeve 2 is arranged in the fixing hole 11 of junction block 1, using two retainer rings, 4 front and back spiral shells is located on the thread 22 of abutment sleeve 2, and packing and abutment sleeve 2 is firmly combined with junction block 1, simultaneously rotary block 3 is limited in the holding tank 25 of abutment sleeve 2, and torque spring 24 is limited in location in the accommodating chamber 23 of abutment sleeve 2, and can not deviate from; Make rotary block 3 in the holding tank 25 of abutment sleeve 2, compressible torque spring 24 rotates in original position, and the rotation limit of its rotary block 3, just is polygonal hole 31 and the overlapping corresponding states of polygonal endoporus 21; When torque spring 24 pushing tow pushing blocks 32, and when making rotary block 3 rotation involutions, the polygonal hole 31 of this rotary block 3 is non-overlapped crossing condition with the polygonal endoporus 21 of abutment sleeve 1; The front end of one lamp stand 5 is established a polygonal bar 51, and in the polygonal hole 31 of rotary block 3 and the polygonal endoporus 21 of abutment sleeve 1 corresponding, and between polygonal bar 51 and lamp stand are by ring 52, establish a draw-in groove 53, and in polygonal bar 51 central shafts to running through electric wire perforation 54, be connected with lamp stand 5; In addition, be positioned at the end face periphery of polygonal bar 51, can be made into chamfering 511, when making polygonal bar 51 enter the polygonal endoporus 21 of abutment sleeve 2, be easier to slip into via the polygonal hole 31 of rotary block 3.

Referring to Fig. 3-A, Fig. 3-B and Fig. 4: when the polygonal bar 51 of lamp stand 5 penetrates the polygonal hole 31 of rotary block 3, this lamp stand 2 reverses rotary block 3 slightly, and the polygonal hole 31 of cooperation rotary block 3 and the polygonal endoporus 21 corresponding states in an overlapping of abutment sleeve 2, the chamfering 511 of the polygonal bar 51 of while mat, and be easy to slip in the polygonal endoporus 21 of abutment sleeve 2, and in lamp stand 5 by ring 52 when being against rotary block 3, this rotary block 3 is just at the polygonal bar 51 of lamp stand 5 and by draw-in groove 53 positions between the ring 52, make above-mentioned rotary block 3 because of being rotated by lamp stand 5, and after making push rod 32 compression torque springs 24.These rotary block 3 anti-torque spring 24 pushing tow rotary blocks 3 that are subjected to turn round involutions, make the polygonal hole 31 of rotary block 3 and the polygonal bar 51 of lamp stand 5 be non-overlapped crossing condition (as shown in Figure 4), make polygonal bar 51 be subjected to stopping of rotary block 3 relatively, thereby make for lamp stand 5 and junction block 1 strong fix, thereby be convenient to user's assembling, and injure electric wire; And when carrying separable disassembling, to reduce its carrying volume of timber and to reduce cost.

Above-mentioned polygonal endoporus 21, polygonal hole 31 and polygonal bar 51 can be made into various geometries, and corresponding mutually collocation.
