The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 2, the quick-insertion cup comb according to the first embodiment of the present invention includes a tubular body, the body includes a socket 1 and a plug 2 located at a front end of the socket 1, and an outer convex ring 3 and an inner convex ring 4 for connection and limiting are disposed between the socket 1 and the plug 2. Set up outer bulge loop 3, when inserting cup comb soon and being connected with junction box body, can restrict the inserted degree of depth of plug 2. The inner convex ring 4 is arranged, so that the insertion depth of the pipe can be limited when the socket is connected with the pipe in a socket mode. The outer convex ring 3 and the inner convex ring 4 improve the stability of quick-insertion cup comb connection, and the damage to the body and/or the junction box body caused by connection dislocation during connection is avoided.

The side wall of the body close to the plug 2 is provided with a pair of through grooves 5 which are symmetrically arranged and are not communicated with the front end of the plug 2, the through grooves 5 are internally provided with elastic blocks 6, the rear ends of the elastic blocks 6 are fixedly arranged on the side wall of the through grooves 5 far away from the plug 2, the front ends of the elastic blocks 6 are provided with clamping bulges 61 which radially extend outwards, and a limiting groove 62 is formed between the clamping bulges 61 and the outer convex ring 3. The engaging projection 61 is higher than the outer side wall of the header 2 but does not exceed the outer peripheral wall of the outer collar 3.

During implementation, when will insert cup comb soon and install on the cup comb hole of junction box body, plug 2 inserts in the cup comb hole, the protruding 61 pressurized elastic block of block is inside 6, thereby make protruding 61 of block smoothly pass through the cup comb hole, elastic block 6 bounces behind the protruding 61 of block through the cup comb hole, protruding 61 of block together bounces, the lateral wall that the cup comb hole located the position this moment is located between protruding 61 of block and evagination ring 3, also be the interior week in spacing recess 62 of cup comb hole, spacing recess 62 through protruding 61 of block and the formation of evagination ring 3 makes the cup comb can't continue radial movement, also be the cup comb is installed on the cup comb hole of junction box body.

Through the specific structure of the quick-insertion cup comb in the embodiment, the quick-insertion cup comb can be quickly installed on the cup comb hole of the junction box body, and the through groove 5 is not communicated with the front end of the plug 2, namely the plug 2 can keep a relatively complete column shape, the front end of the plug can not be divided into multiple sections, when the quick-insertion cup comb is subjected to radial force, the relatively complete cylindrical plug 2 can not be easily deformed, so that the whole plug 2 can keep certain strength and is not easy to deform, and the stability of the quick-insertion cup comb installed on the junction box body can be ensured; on the other hand, the conditions of scraping, damaging and the like to the electric wire can be ensured in the wire pulling process.

The clamping protrusion 61 is an inclined surface 611 on one side close to the plug 2, and the height of the lowest part of the inclined surface 611 is equal to or less than the height of the outer side wall of the plug 2, so that the clamping protrusion 61 can automatically and rapidly move inwards when passing through the cup combing hole, and the clamping protrusion 61 can more smoothly pass through the cup combing hole, so that rapid installation of the fast-insertion cup comb is realized. The limiting groove 62 is higher than the outer side wall of the plug 2, so that the plug 2 can be inserted into the cup comb hole more easily, and the limiting groove 62 can generate extrusion force on the peripheral wall of the cup comb hole to clamp the plug more conveniently.

Preferably, the outer diameter of the socket 1 is smaller than the outer diameter of the plug 2.

Preferably, the socket 1 has an inner diameter smaller than the inner diameter of the spigot 2.

Preferably, the width of the limit groove 62 matches the thickness of the side plate of the junction box body.

Preferably, the bottom surface of the limiting groove 62 is a cambered surface.

Preferably, the inner diameter of the socket 1 is provided with a quick insertion slope α, and the radial section of the inner diameter of the socket 1 gradually increases from the inner ring 4 in the direction away from the plug 2. The fast insertion inclination alpha is 1.2-1.6 degrees. Referring to fig. 3, in the present embodiment, the fast insertion inclination α is 1.4 °. When the pipe is inserted into the socket 1, the radial section of the inner diameter of the socket 1 is gradually increased from the inner ring 4 to the direction away from the plug 2, namely, the inner diameter of the socket 1 is smaller as the pipe is closer to the plug 2, namely, the pipe is inserted deeper and tighter.

In the utility model, the quick-insertion cup comb is convenient to use and install, and the opening end of the body is of a closed annular structure, so that the conditions of scraping, damaging and the like to electric wires in the wire pulling process can be avoided.
