In order to achieve the above purpose, the utility model provides a prefabricated cable duct bank elbow, which comprises an elbow body and positioning sleeves which are sleeved at the two ends of the elbow body and extend; the elbow body comprises a plurality of elbows matched with the cable duct bank to be connected and a connecting part for connecting two adjacent elbows, wherein the connecting part is made of rubber materials so as to enable the two adjacent elbows to form elastic fixed connection; the positioning sleeve is made of elastic materials, the cross section of the positioning sleeve is consistent with the outer contour of the elbow body, the positioning sleeve comprises an annular positioning sleeve body sleeved on the elbow body and a clamping wall which is convexly extended from the inner side of the positioning sleeve body, the clamping wall extends along the direction of the positioning sleeve body, and the clamping wall is inserted between two adjacent elbows which are abutted against the outermost periphery of the elbow body.
Preferably, the elbow body and the positioning sleeve are of an integrally formed structure.
Preferably, the prefabricated cable duct bank elbow further comprises an elastic reinforcing part sleeved on the positioning sleeve, and the natural cross-sectional area of the elastic reinforcing part is smaller than that of the positioning sleeve.
Compared with the prior art, the utility model provides a prefabricated cable duct bank elbow comprises an elbow body and a positioning sleeve which is sleeved at the two ends of the elbow body and extends, wherein the elbow body comprises a plurality of mutually connected elbows for connecting with a cable duct bank to be connected; realize the prepositioning with a plurality of elbows behind the cable duct bank of treating the connection through the direct cover of positioning sleeve to can once only realize the erection joint with cable duct bank and a plurality of elbows, the installation effectiveness is high.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
fig. 1 is a schematic three-dimensional structure diagram of the prefabricated cable duct bank elbow of the present invention;
fig. 2 is the schematic sectional view of the prefabricated cable duct elbow of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a prefabricated cable duct bank elbow 100, which comprises an elbow body 1 and a positioning sleeve 2 covering and extending from two ends of the elbow body 1.
The elbow body 1 comprises a plurality of elbows 11 matched with a cable duct bank to be connected and a connecting part 12 for connecting two adjacent elbows.
In this embodiment, the connecting portion 12 is made of rubber material, so that two adjacent elbows 11 form an elastic fixed connection. When the cable duct bank is connected and installed at the turning position through the prefabricated cable duct bank elbow 100, a certain displacement adjusting space is formed between the elbows 11 which are connected in an elastic and fixed mode, the precision requirement of the cable duct bank when the turning position is connected is effectively reduced, and therefore the installation efficiency is improved. And the elastic connection can adapt to the error of the specification of the distance between the rows of the cable tubes, so that the connection is more convenient.
The positioning sleeve 2 is made of elastic materials, and the cross section of the positioning sleeve 2 is consistent with the outer contour of the elbow body 1.
Specifically, the positioning sleeve 2 includes an annular positioning sleeve body 21 sleeved on the elbow body 1 and a clamping wall 22 protruding and extending from the inner side of the positioning sleeve body 21, in this embodiment, the clamping wall 22 extends along the direction of the positioning sleeve body, so that the clamping wall 22 is consistent with the positioning sleeve body 21 in length.
The clamping wall 22 is inserted and abutted between two adjacent elbows 11 at the outermost periphery of the elbow body 1. This structure setting can effectual improvement elbow body 1 and the intensity between the position sleeve 2, avoids connecting cable calandria to cause the fracture because of the construction skew, has improved the reliability. And the setting of double-layered wall 22 gets up the guide effect when treating the connecting cable calandria, can make the light cover of position sleeve 2 establish to treating the connecting cable calandria, further improves installation effectiveness, and installation back double-layered wall 22 presss from both sides and locates between two adjacent calandrias of the outermost periphery of connecting cable calandria, improves joint strength.
In this embodiment, the elbow body 1 and the positioning sleeve 2 are integrally formed.
More excellent, for the improvement connects the assembly reliability, prefabricated cable duct bank elbow 100 is still located including the cover the elasticity reinforcement 3 of positioning sleeve 2, the cross sectional area of 3 natural states of elasticity reinforcement is less than positioning sleeve 2's cross sectional area, because of elasticity reinforcement 3 has elasticity, establish when 2 covers of positioning sleeve and install in treating the cable duct bank after, draw elasticity reinforcement 3 to make its deformation and cover greatly and locate to correspond and treat the connection cable duct bank on, loosen external force and then resume elastic deformation to strengthen positioning sleeve 2 and treat the reliability that the connection cable duct bank is connected.
Compared with the prior art, the utility model provides a prefabricated cable duct bank elbow comprises an elbow body and a positioning sleeve which is sleeved at the two ends of the elbow body and extends, wherein the elbow body comprises a plurality of mutually connected elbows for connecting with a cable duct bank to be connected; realize the prepositioning with a plurality of elbows behind the cable duct bank of treating the connection through the direct cover of positioning sleeve to can once only realize the erection joint with cable duct bank and a plurality of elbows, the installation effectiveness is high.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
