Description

Fixed connection device

Technical Field

The utility model relates to a fixed connection device belongs to the machine-building technology field.

Background

When two different parts and devices are connected and fixed together, holes are usually drilled on the joint surfaces of the parts and the devices, and then the parts and the devices are fastened and connected through connecting bolts. However, for equipment which is narrow in space and cannot design a whole contact surface hole to install a connecting bolt or other equipment with high difficulty in installing the connecting bolt, the difficulty of fixed connection is remarkably upgraded.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a fixed connection device is used for solving above-mentioned problem.

In order to realize the purpose, the utility model discloses a technical scheme is:

a fixed connecting device comprises a fixed hook and a bottom plate which are fixedly arranged on a first device and a second device which need to be fixedly connected respectively, wherein two long grooves are formed in the bottom plate, the fixed hook and the bottom plate are fixedly connected through the connecting hook, the connecting hook comprises a connecting rod matched with the fixed hook, two ends of the connecting rod are fixedly connected with inserting rods matched with the long grooves, and threads matched with nuts are machined at the end parts of the inserting rods.

The utility model discloses technical scheme's further improvement lies in: the fixed hook is a J-shaped hook and is welded on the first equipment.

The utility model discloses technical scheme's further improvement lies in: the connecting hook is formed by welding three round steel bars.

The utility model discloses technical scheme's further improvement lies in: the bottom plate is a steel plate and is welded to the second equipment.

Since the technical scheme is used, the utility model discloses the technological effect who gains has:

the utility model discloses simple structure, the accessory is easy, and the processing cost is low, is applicable to the equipment that the whole contact surface trompil of space is narrow and small, unable design comes erection joint bolt or other erection joint bolt big equipment of the degree of difficulty.

The utility model discloses a bottom plate processing has two elongated slots, even two equipment positions of connecting have the condition of dislocation, also can connect fixedly very conveniently.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a side view of the fixing hook of the present invention;

fig. 3 is a side view of the coupling hook of the present invention;

the device comprises a base, a fixing hook 1, a connecting hook 2, a connecting rod 2-1, an inserting rod 3, a nut 4, a bottom plate 4-1, an elongated slot 5, a first device 6, a second device 6 and a connecting rod 2-2.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments:

a fixed connection device, as shown in figure 1, comprises a fixed hook 1 and a bottom plate 4 which are respectively and fixedly arranged on a first device 5 and a second device 6 which need to be fixedly connected. As shown in fig. 2, the fixed hook 1 is a J-shaped hook and is welded on a first device 5; the bottom plate 4 is a steel plate and is welded on the second equipment 6. Two long grooves 4-1 are formed in the bottom plate 4, and the long grooves 4-1 are uniformly distributed on the bottom plate 4. The fixed hook 1 and the bottom plate 4 are fixedly connected through a connecting hook 2, as shown in fig. 3, the connecting hook 2 comprises a connecting rod 2-1 matched with the fixed hook 1, two ends of the connecting rod 2-1 are fixedly connected with inserting rods 2-2 matched with the elongated slots 4-1, threads matched with the nuts 3 are machined at the ends of the inserting rods 2-2, and the connecting hook 2 is formed by welding three round steel bars.

When the device is applied, the mutually matched fixed hook 1 and the bottom plate 4 are welded on the first device 5 and the second device 6 respectively, the connecting rod 2-1 of the connecting hook 2 is placed on the hook part of the fixed hook 1, the two inserting rods 2-2 are inserted into the two long grooves 4-1 respectively, and finally the two inserting rods are screwed and fixed by the nuts 3.

The utility model discloses simple structure, the accessory is easy, and the processing cost is low, is applicable to the equipment that the space is narrow and small, can't design whole contact surface trompil and come installation connecting bolt or other installation connecting bolt big equipment of the degree of difficulty.
