Description
Technical Field
The invention relates to a handcart type switch contact finger installation tool.
Background
The handcart switch contact finger is formed by connecting four springs, and the contact finger is required to be spread when in use, then sleeved into a position to be installed, and then loosened to clamp the contact finger to finish installation. At present, no mature installation tool is available on the market, two persons need to operate together when the installation is carried out, time and labor are wasted, the hands of operators are easily injured, and great inconvenience is caused for maintenance work.
Disclosure of Invention
The invention aims to solve the technical problem of providing a handcart type switch contact finger installation tool which is simple to operate and convenient to install.
The technical scheme adopted by the invention is as follows: a handcart type switch contact finger mounting tool comprises a sleeve in a frustum-shaped structure, a cylindrical mounting cylinder arranged at the top of the sleeve, a mounting nut fixedly arranged in the mounting cylinder, a support rod arranged in the mounting nut through threaded connection, four grooves arranged at the bottom of the sleeve and a support structure arranged at the bottom of the support rod; the four grooves at the bottom of the sleeve divide the lower end of the sleeve into four adjusting sheets, a supporting rod is arranged in each adjusting sheet, and the supporting structure is four gradual-change bulges which are arranged at the bottom of each supporting rod and used for being connected with the supporting rod.
The support rod is circular, and on the radial section, the distance between the gradual change bulge and the circle center of the support rod is gradually increased along the counterclockwise direction.
The height of the gradual change bulge on the axial section is gradually increased from top to bottom.
The grooves are uniformly formed in the sleeve, and the gradually-changed bulges are uniformly formed in the supporting rod.
One end of the support rod is fixedly connected with the adjusting sheet, and the other end of the support rod is provided with the pulley which is used for being in contact with the gradual change bulge.
The top of the support rod is provided with the handle, and the middle of the support rod is provided with the threads.
The invention has the positive effects that: the invention adopts a frustum-shaped sleeve structure, the small head can be sleeved inside the handcart-type switch contact finger, then the handcart-type switch contact finger is pushed downwards to prop open the contact finger by utilizing the gradually-changed outer diameter of the sleeve, the bottom of the sleeve is sleeved on the position to be installed, the contact finger can be directly installed in place, the operation can be completed by one person, and the operation is simple and convenient. Meanwhile, the adjusting sheet is arranged at the bottom of the sleeve, and the adjusting sheet can be outwards supported through the supporting structure and the supporting rod, so that the outer diameter of the sleeve is adjusted, the contact finger can be supported to different sizes, and the touch finger support device is suitable for different installation conditions.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic cross-sectional view of the present invention;
FIG. 3 is a schematic view of a structure of a gradual bump according to the present invention.
Detailed Description
As shown in the attached drawings 1 and 2, the invention comprises a sleeve 1 in a frustum structure, a cylindrical mounting cylinder 2 arranged at the top of the sleeve 1, a mounting nut 9 fixedly arranged in the mounting cylinder 2, a stay bar 3 arranged in the mounting nut 9, four grooves 4 arranged at the bottom of the sleeve 1 and a supporting structure arranged at the bottom of the stay bar 3; the top of the stay bar 3 is provided with a handle 10, the middle part of the stay bar 3 is provided with threads, and a limit plate 11 is arranged below the threads. The four grooves 4 evenly arranged at the bottom of the sleeve 1 divide the lower end of the sleeve 1 into four adjusting sheets 8, a support rod 6 is arranged in each adjusting sheet 8, and the support structure is four gradual-change bulges 5 evenly arranged at the bottom of the support rod 3 and used for being connected with the support rod 6.
As shown in fig. 2 and 3, the stay bar 3 is circular, and in a radial cross section, the distance between the gradual change protrusion 5 and the center of the stay bar 3 gradually increases in the counterclockwise direction, and in an axial cross section, the height of the gradual change protrusion 5 gradually increases from top to bottom. Through rotatory vaulting pole 3 under threaded connection's effect, vaulting pole 3 upwards moves gradually the gradual change arch 5 that becomes high and jack-up bracing piece 6, simultaneously because rotatory vaulting pole 6 of rotatory vaulting pole 3 and gradually change arch 5 take place offset in the horizontal direction, equally can jack-up bracing piece 6, simultaneously because threaded connection's effect, vaulting pole 3 can not be because of bracing piece 6 pressure automatic reversal.
Further, in order to ensure that the supporting rod is convenient to recycle, complicated adjusting steps are omitted, on the radial section, the rear end circular arc transition of the structure with the gradually-increasing distance between the gradually-changing protrusion 5 and the circle center of the supporting rod 3 is provided with the gradually-decreasing structure, namely, the distance between the gradually-changing protrusion 5 and the circle center of the supporting rod 3 is gradually decreased after being gradually increased, and therefore the supporting rod 6 can be supported no matter the supporting rod 3 rotates forwards and backwards.
One end and the trimmer 8 fixed connection of bracing piece 6, the other end are provided with pulley 7, pulley 7 is used for contacting with gradual change arch 5, and is preferred, and pulley 7 adopts the universal wheel structure, guarantees the smoothness nature of adjustment, adjusts more laborsavingly.
The handcart type switch contact finger mounting structure can greatly simplify the mounting process of the handcart type switch contact finger, accelerate the mounting speed, realize the use of mounting parts with different outer diameters and have wider application range.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
