Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, and particularly relates to a tool for assisting in casing. Background Technique

[0002] In the power field, copper tubes and copper rods are widely used. When a copper rod is sleeved with a copper tube on the outside, this combination is mainly used in power transmission and distribution systems. This is because copper has good electrical conductivity and can effectively transmit electrical energy. In addition, the high electrical conductivity and high temperature resistance of copper make it an indispensable material in power systems. Copper tube busbars, as a common conductive device in power systems, are usually used in power transmission and distribution systems and play a key role in transmitting electrical energy. This combination not only has good electrical conductivity but also has high temperature resistance, ensuring the safe and stable operation of power systems.

[0003] In the operation of the prior art, when a copper tube is sleeved on the outer periphery of a copper rod, due to the friction between the inner wall of the copper tube and the outer periphery of the copper rod, the insulating layer on the outer periphery of the copper rod is easily worn, thus affecting the accuracy of the copper rod in later processing. Content of the Utility Model

[0004] The utility model solves the problems in the related art and provides a tool for assisting in casing, which reduces the resistance when the copper rod is inserted into the inner wall of the copper tube.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions: A tool for assisting in casing includes a copper tube, a copper rod sleeved in the inner cavity of the copper tube, and an auxiliary protective cylinder arranged between the copper tube and the copper rod to facilitate the movement of the copper rod in the copper tube;

[0006] The auxiliary protective cylinder includes a limiting cylinder for sleeving the top of the steel rod, a contact column connected to the limiting cylinder

[0007] a plurality of balls uniformly arranged on the contact column, and limiting holes arranged on the contact column and adapted to the balls, and the balls are rotatably connected to the limiting holes.

[0008] By adopting the above technical solutions, the design of the balls effectively reduces the resistance when the copper rod is inserted into the inner wall of the copper tube, thus facilitating the quick installation of the copper rod in the copper tube for movement, and has the characteristics of time saving and labor saving.

[0009] Optionally, the limiting cylinder and the contact column are integrally formed, the outer periphery of the limiting cylinder is set as a smooth arc surface, the outer diameter of the limiting cylinder is smaller than the inner diameter of the steel tube, and the length of the limiting cylinder is set to be 1 / 4 of the length of the auxiliary protective cylinder.

[0010] Such a design effectively avoids the contact between the auxiliary casing and the inner wall of the steel pipe, facilitating the quick sleeving of the steel pipe around the outer periphery of the auxiliary casing.

[0011] Optionally, a limiting hole adapted to the steel rod is provided on the upper part of the limiting cylinder, and an anti-slip gasket is arranged on the inner wall of the limiting hole;

[0012] The anti-slip gasket increases the friction between the limiting hole and the steel rod, effectively ensuring the stability of the connection between the limiting cylinder and the steel rod.

[0013] The contact post is one of a stepped shape or a cylindrical shape, and the outer diameter of the contact post is smaller than the outer diameter of the limiting cylinder.

[0014] Such a design makes the contact part between the contact post and the inner wall of the steel pipe be a ball, enabling the steel pipe to quickly move downward by the rolling action of the ball.

[0015] Optionally, adjacent balls are arranged in a staggered manner. Each ball is spherical, and the outer periphery of the ball is a smooth arc surface.

[0016] By adopting the above technical solution, the design of the ball effectively reduces the resistance when the copper rod is inserted into the inner wall of the copper pipe.

[0017] Optionally, the upper end of the auxiliary casing is a solid structure, and the auxiliary casing is made of copper.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: the present utility model;

[0019] 1. The stepped design of the contact post in the auxiliary casing effectively reduces the contact area between the auxiliary casing and the steel pipe, and facilitates the guiding of the steel pipe during the pushing process;

[0020] 2. The design of the ball makes the contact part between the contact post and the inner wall of the steel pipe be a ball, enabling the steel pipe to quickly move downward by the rolling action of the ball, effectively reducing the resistance when the copper rod is inserted into the inner wall of the copper pipe, and thus facilitating the quick installation of the copper rod into the copper pipe, with the characteristics of time and labor saving;

[0021] 3. The copper rod is inserted into the copper pipe, and the use of the auxiliary casing facilitates the insertion and subsequent removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] It should be noted that the terms used here are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. Without contrary statements, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0034] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationships of one device or feature and other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0035] In addition, it should be noted that the use of words such as "first", "second" to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meanings, and thus cannot be construed as limiting the protection scope of the present invention.

[0036] AsFigures 1 to 6 As shown in the figure, a tool for an auxiliary sleeve includes a copper tube 1, a copper rod 4 sleeved in the inner cavity of the copper tube 1, and an auxiliary cylinder 2 arranged between the copper tube 1 and the copper rod 4 to facilitate the movement of the copper rod 4 in the copper tube 1. The upper end of the auxiliary cylinder 2 is set as a solid structure, and the auxiliary cylinder 2 is made of metallic copper. The auxiliary cylinder 2 includes a limiting cylinder 21 for sleeving the top of the steel rod, a contact column 22 connected to the limiting cylinder 21, rolling balls 31 uniformly arranged on the contact column 22, and limiting holes 311 arranged on the contact column 22 and adapted to the rolling balls 31. The rolling balls 31 and the limiting holes 311 are rotatably connected to each other. The design of the rolling balls 31 effectively reduces the resistance when the copper rod 4 is inserted into the inner wall of the copper tube 1, thus facilitating the quick installation of the copper rod 4 in the copper tube 1 and enabling it to move conveniently in the copper tube 1 and be pushed out, which has the characteristics of time and labor saving.

[0037] As Figure 1 shown in the figure, among them, the limiting cylinder 21 and the contact column 22 are integrally formed. The outer periphery of the limiting cylinder 21 is set as a smooth arc surface, and the outer diameter of the limiting cylinder 21 is smaller than the inner diameter of the steel tube. The length of the limiting cylinder 21 is set to 1 / 4 of the length of the auxiliary cylinder 2, effectively avoiding the contact between the auxiliary cylinder 2 and the inner wall of the steel tube, thus facilitating the quick sleeving of the steel tube on the outer periphery of the auxiliary cylinder 2.

[0038] As Figure 2 and Figure 3 shown in the figure, the limiting cylinder 21 is provided with limiting holes 311 adapted to the steel rod. The inner wall of the limiting holes 311 is provided with an anti-slip gasket, and the anti-slip gasket increases the friction between the limiting holes 311 and the steel rod, thus effectively ensuring the stability of the connection between the limiting cylinder 21 and the steel rod.

[0039] As Figure 3 shown in the figure, the contact column 22 is set as one of a stepped shape or a cylindrical shape, and the outer diameter of the contact column 22 is smaller than the outer diameter of the limiting cylinder 21, so that the part of the contact column 22 in contact with the inner wall of the steel tube is the rolling ball 31, enabling the steel tube to quickly move downward by the rolling action of the rolling ball 31.

[0040] As Figure 2 and Figure 3 shown in the figure, in addition, the adjacent rolling balls 31 are arranged in a staggered manner. Each rolling ball 31 is set as a spherical shape, and the outer periphery of the rolling ball 31 is set as a smooth arc surface. The design of the rolling balls 31 effectively reduces the resistance when the copper rod 4 is inserted into the inner wall of the copper tube 1.

[0041] In this embodiment, during use, one end of the steel rod 4 is inserted into the limiting cylinder 21 of the auxiliary cylinder 2, and then the steel tube 1 is sleeved from the contact column 22 at the other end of the auxiliary cylinder 2. The inner wall of the steel tube 1 moves downward due to the rolling action of the rolling balls 31 on the outer periphery of the contact column until the steel tube 2 completely covers the steel rod 4, and then the auxiliary cylinder 2 can be removed.

[0042] The above is the preferred embodiment of the present utility model. Those skilled in the art to which the present utility model pertains are also able to make changes and modifications to the above embodiment. Therefore, the present utility model is not limited to the above specific embodiment, and any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present utility model all fall within the protection scope of the present utility model.
