Abstract

The utility model discloses a simple and quick connecting device which comprises a main shaft, a pin, and a pull ring. The device is characterized in that the main shaft is of a T-shaped structure; a vertical shaft of the main shaft enters a through hole of a to-be-connected part to connect the to-be-connected part; the vertical shaft is provided with a transverse through hole in the tail end; the pin is of a T-shaped structure; a transverse shaft of the pin is a square block; a vertical shaft of the pin is inserted into the transverse through hole; a side face of the square block vertical to the main shaft is attached to the to-be-connected part; each of two side faces of the square block parallel to the main shaft is provided with a through hole for installation of the pull ring, and the through holes are arranged in a staggered manner; two ends of the pull ring are arranged through and fixed to the two through holes of the square block respectively; and the central part of the pull ring winds around the vertical shaft of the main shaft 1 and is fixed to a hook at the tail end of the pin. With the above structure, the device can achieve dynamic connection between mechanical bearing parts, allows quick connection and disconnection, and is simple in structure with good economic benefits.

Description

A kind of simple and fast jockey

Technical field

The utility model belongs to machinery industry field, is specifically related to a kind of easy Quick Connect Kit.

Background technology

Quick Connect Kit kind is more at present, most of for the static state connection between non-bearing part, such as the quick locking between the plug and socket of electric connector and release, but less for what dynamically connect between mechanical bearing member, mechanism is more complicated all, and cost is higher.

Utility model content

For the defect of prior art, the purpose of this utility model is to provide a kind of easy Quick Connect Kit, can realize the function that connects and dismantle fast between mechanical bearing member.

For achieving the above object, the utility model provides a kind of simple and fast jockey, comprises main shaft, bearing pin, draw ring, is characterized in that, main shaft is T-shaped structure, and its vertical pivot connects for penetrating in the through hole of two parts to be connected, and perpendicular the tip of the axis is provided with horizontal through hole;

Bearing pin is T-shaped structure, and its transverse axis is square, in the laterally inserted described through hole of its vertical pivot;

A side and parts to be connected that described square is vertical with described main shaft are adjacent to;

Described square two sides parallel with described main shaft are respectively arranged with the through hole for draw ring is installed;

Two ends of described draw ring wear is respectively fixed on described through hole, and its middle part is walked around on the perpendicular the tip of the axis hanger pin the tip of the axis of main shaft.

Further, described through hole is arranged in the mode staggering each other in the plotted of bearing pin.

The technical program is applicable to the dynamic connection between mechanical bearing member, not only can complete the function of quick connection and dismounting, and simple in structure, good in economic efficiency.

Brief description of the drawings

The structural profile schematic diagram of a kind of simple and fast jockey that Fig. 1 provides for the utility model;

The vertical view of a kind of simple and fast jockey that Fig. 2 provides for the utility model;

Wherein: the through hole 2-bearing pin 2-1 on 1-main shaft 1-1 main shaft, 2-2-through hole 3-draw ring 4-workpiece I 5-workpiece II.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.In addition,, in each execution mode of described the utility model, involved technical characterictic just can combine mutually as long as do not form each other conflict.

As shown in Figure 1, main shaft 1 mainly plays load effect, and it is a T-shaped structure, and vertical pivot tip designs has a through hole 1-1, and main shaft 1 penetrates in the hole of workpiece I 4 and workpiece II 5 and connects.Bearing pin 2 is also T-shaped structure, and its transverse axis is a square design, and two sides parallel with main shaft 1 on its square are designed with respectively through hole 2-1,2-2, and two through holes are crisscross arranged, and vertical pivot is slender axles design.

Bearing pin 2 is inserted in the through hole 1-1 of main shaft 1 vertical pivot end, the outer surface of workpiece I 4 is pressed close in a square side vertical with main shaft simultaneously, the axial displacement of bearing pin 2 major limitation main shafts 1, prevents that by its locking main shaft 1 from coming off out from the through hole of workpiece I 4 and workpiece II 5.

Draw ring 3 is the design of spring shape, and one end is located in two through hole 2-1 of bearing pin 2 square, and in 2-2, one end is linked up with to be connected to realize with the end of bearing pin 2 and is connected and fixed in addition;

Draw ring 3 can serve as handle can provide under external force again deformation energy as spring, thereby by fixing bearing pin 2, and then by fixing main shaft 1, workpiece I 4 and workpiece II 5 are reliably connected the most at last.

Wherein, the operation principle of this jockey is as follows:

When connection, main shaft 1 is inserted in the hole of workpiece I 4 and workpiece II 5 and connect, bearing pin 2 is inserted in the through hole 1-1 of main shaft 1 vertical pivot end, the axial displacement of the square restriction main shaft 1 of fitting with workpiece I 4 that simultaneously relies on main shaft 1T type transverse axis and bearing pin 2, direction to bearing pin vertical pivot end is rotated draw ring 3, draw ring 3 compression accumulation of distortion energy, when draw ring 3 is pressed also completely, deformation energy reaches maximum, being rotated further draw ring 3 links up with in bearing pin vertical pivot end, deformation energy discharges a part draw ring 3 is withstood on the side of workpiece I 4, remaining deformation energy is firmly pressed close to draw ring 3 on the side of workpiece I 4, simultaneously draw ring 3 can prevent that bearing pin 2 from deviating from the through hole 1-1 of main shaft 1.

When dismounting, direction to square is rotated draw ring 3, overcome residual deformation and draw ring 3 can be gone to bearing pin 2 square one sides, bearing pin 2 is extracted out, again main shaft 1 is extracted out, thereby workpiece I 4 and workpiece II 5 are dismantled, the mode that adopts through hole to be crisscross arranged, the spring force that can utilize draw ring to produce is treated link and is realized fixing further.

Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
