Description
Technical Field
The utility model belongs to the technical field of the connecting rod, especially, relate to special-shaped spanner connecting rod.
Background
A wrench is a common mounting and dismounting tool, and is a hand tool for screwing bolts, screws, nuts and other screw threads to tightly hold open or trepanning fasteners of the bolts or the nuts by utilizing the lever principle.
But generally adopt the steel ball location between current dysmorphism open-ended spanner and the connecting rod, the advantage lies in to connect conveniently, locks effectually, but is more difficult when separating dysmorphism open-ended spanner and connecting rod, causes inconvenience for the staff.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems in the prior art and providing a special-shaped spanner connecting rod.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
dysmorphism spanner connecting rod, including the connecting rod, the one end of connecting rod is equipped with the spliced eye, it is equipped with special-shaped open spanner to slide to insert in the spliced eye, the one end that special-shaped open spanner is close to the spliced eye notch is equipped with the device chamber, be equipped with two sliders that the symmetry set up in the device chamber, two spring coupling is passed through to the relative one side of slider, two the equal fixedly connected with ejector pin of one end that the spring was kept away from to the slider, the inner wall in device chamber is run through and outwards extends to the one end of ejector pin, the one end fixedly connected with arc dop that the ejector pin extends, be equipped with the arc.
Preferably, an anti-slip sleeve is fixedly sleeved at one end of the connecting rod, which is far away from the special-shaped open wrench.
Preferably, a reflective sticker is bonded on the connecting rod.
Preferably, the connecting rod is fixedly sleeved with a protection ring.
Has the advantages that:
1. the utility model discloses in, during the use, insert the spliced eye with one end of dysmorphism open-ended spanner in, make the spliced eye in the connecting rod compress the spring in the device groove, then play the effect of elastic support to the arc dop in the in-process of inserting, thereby make the arc dop insert and fix the dysmorphism open-ended spanner in the corresponding arc draw-in groove, when needing to break away from, press the arc dop, make the arc dop drive the spring and compress, the arc dop falls wholly and slides into the device groove, connecting rod and dysmorphism open-ended spanner just unblock and break away from fast; after the arc-shaped clamping head is loosened, the spring pushes the ejector rod to push the top of the arc-shaped clamping head to extend out of the arc-shaped clamping groove, the requirement that high-speed rail night operation must have a light-reflecting mark on a tool is met through the arrangement of the light-reflecting paste, the requirement of maintenance safety is met, and the friction force when the connecting rod is held can be increased through the arrangement of the anti-skidding sleeve.
2. The utility model discloses a setting of elasticity latch mechanism, the special-shaped open spanner of being convenient for and the connecting rod carry out quick assembly disassembly, lock effectual, convenient to use.
Drawings
FIG. 1 is a schematic structural view of a special-shaped wrench connecting rod;
fig. 2 is a schematic structural diagram of a point a in fig. 1.
In the figure: 1-connecting rod, 2-special-shaped open spanner, 3-sliding block, 4-spring, 5-ejector rod, 6-arc clamping head, 7-anti-slip sleeve, 8-reflecting sticker and 9-protective ring.
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.
Referring to fig. 1-2, dysmorphism spanner connecting rod, including connecting rod 1, the one end of connecting rod 1 is equipped with the spliced eye, it is equipped with dysmorphism open-ended spanner 2 to slide to insert in the spliced eye, the one end that dysmorphism open-ended spanner 2 is close to the spliced eye notch is equipped with the device chamber, be equipped with two sliders 3 that the symmetry set up in the device chamber, spring 4 connection is passed through to two slider 3 relative one side, the equal fixedly connected with ejector pin 5 of one end that spring 4 was kept away from to two sliders 3, the inner wall in device chamber is run through and outwards extends to the one end of ejector pin 5, the one end fixedly connected with arc dop 6 that ejector pin.
In this embodiment, the fixed cover that has connect has antiskid cover 7 in the one end that connecting rod 1 kept away from special-shaped open end spanner 2, bonds on connecting rod 1 and has reflected light subsides 8, and the fixed cover that has connected has guard circle 9 on connecting rod 1.
In the embodiment, when the special-shaped open spanner is used, one end of the special-shaped open spanner 2 is inserted into the inserting hole, so that the inserting hole in the connecting rod 1 compresses the spring 4 in the device groove, the arc-shaped clamping head 6 plays a role of elastic support in the inserting process, the arc-shaped clamping head 6 is inserted into the corresponding arc-shaped clamping groove to fix the special-shaped open spanner 2, when the special-shaped open spanner needs to be separated, the arc-shaped clamping head 6 is pressed down, the arc-shaped clamping head 6 drives the spring 4 to be compressed, the arc-shaped clamping head 6 integrally falls and slides into the device groove, and the connecting rod 1 and the special-shaped open spanner 2 are unlocked and quickly separated; after the arc-shaped clamping head 6 is loosened, the spring 4 pushes the ejector rod 5 to push the top of the arc-shaped clamping head 6 to extend out of the arc-shaped clamping groove, the requirement that a high-speed rail needs to be provided with a light-reflecting mark for a tool at the upper part in night operation is met through the arrangement of the light-reflecting sticker 8, the maintenance safety requirement is ensured, and the friction force when the connecting rod 1 is held can be increased through the arrangement of the anti-skidding sleeve 7.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
