Description

Adapter used in narrow space

Technical Field

The technical scheme of the invention relates to an adapter used in a narrow space, in particular to equipment adopting an external shell, an input shaft, a bearing, a bevel gear, an output shaft and an output end, and belongs to the field of building installation equipment.

Background

In the building installation work, many places all involve installation bolt nut in narrow space, perhaps at narrow local mounting flange, equipment fixing in the narrow space is comparatively complicated, can be many times because installation space is limited, spanner and electronic hand drill all can't go into the installation, and relevant workman can only think the way to the greatest extent and just can accomplish the installation. The installation in this kind of narrow space mainly embodies in the vertical direction, and the installation obstacle in the vertical direction makes electronic hand drill unable work usually, and then installer need adopt manual mode to install, and manual installation is wasted time and energy, and its work efficiency also is far less than the efficiency of adopting electronic hand drill installation simultaneously, has brought a lot of inconveniences for relevant work.

In the prior art, there is no good solution, so it is necessary to design a device that can solve the current situation of inconvenient installation in a vertically narrow space, so that an installer can complete related work by an electric drill in the narrow space.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, and provides an adapter used in a narrow space, which can solve the problem of inconvenient installation in the narrow space in the vertical direction, so that an installer can complete related installation work through an electric drill in the narrow space, and the defects in the prior art are overcome.

The invention is realized by the following technical scheme:

the utility model provides an adapter that uses in narrow space, includes outside casing, input shaft, bearing, bevel gear, output shaft and output, outside casing is right angle shape, and inside cavity, and both ends are equipped with the through-hole, and input shaft and output shaft are respectively through the rotatable through-hole of installing at both ends of bearing, bevel gear is provided with four altogether, all installs inside outside casing, and two liang of mutual relative intermeshing installation that carries out, two mutually perpendicular's bevel gear respectively with input shaft and output shaft looks rigid coupling, two mutually perpendicular's bevel gear pass through the rotatable installation of bearing inside outside casing in addition, output and output shaft one end looks rigid coupling.

The bearing comprises a large bearing and a small bearing, the large bearing is used for mounting the input shaft and the output shaft, and the small bearing is used for a bevel gear mounted on the outer shell.

Two large bearings are respectively arranged on the input shaft and the output shaft, and the two large bearings are arranged in parallel.

The output end adopts an inner hexagonal interface.

The middle part of the outer shell is spherical.

The above-mentioned adapter for use in narrow spaces, the components of which are well known to those skilled in the art, are obtained in a manner known per se, the method of connecting said components being well known to those skilled in the art.

The electric drill has the beneficial effects that the device can solve the current situation of inconvenient installation in a narrow space in the vertical direction, so that installation personnel can complete related installation work through the electric drill in the narrow space, the working efficiency is improved, and the labor intensity of the related personnel is reduced. The device adopts two pairs of bevel gear pairs, so that the output end can not generate large bending moment when the input end inputs torque, and the output end can be prevented from side bending; two large bearings are respectively arranged on the input shaft and the output shaft, so that the centering property of the shaft is ensured, the vibration of the shaft is reduced to a greater extent, and the stability of the shaft is improved; the output end adopts the socket head cap interface commonly used in the electric drill, so that the device can be matched with a plurality of existing devices for use.

Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in fig. 1 to 4, the adapter used in a narrow space of the present invention includes an external housing 7, an input shaft 1, a bearing, a bevel gear 3, an output shaft 6 and an output end 5, wherein the external housing 7 is right-angled, the middle portion is spherical, the external housing 7 is hollow, and both ends are provided with through holes, and the input shaft 1 and the output shaft 6 are rotatably mounted in the through holes at both ends through the bearing, respectively.

The bevel gears 3 are arranged in four, and are all installed inside the external shell 7, the bevel gears are installed in a mutually meshed mode in pairs, the two bevel gears 3 which are perpendicular to each other are fixedly connected with the input shaft 1 and the output shaft 6 respectively, the other two bevel gears 3 which are perpendicular to each other are installed inside the external shell 7 in a rotating mode through bearings, the bearings are divided into a large bearing 2 and a small bearing 4, the large bearing 2 is used for installing the input shaft 1 and the output shaft 6 to improve the stress performance of the input shaft 1 and the output shaft 6, the small bearing 4 adopted by the bevel gears 3 installed on the external shell 7 is used for reducing the size of the external shell 7, and too much space inside the external shell 7 is not occupied. Two large bearings 2 are respectively arranged on the input shaft 1 and the output shaft 6, and the two large bearings are arranged in parallel, so that the stability of the input shaft 1 and the output shaft 6 is improved, and the condition that the input shaft 1 and the output shaft 6 are laterally deviated or shaken is prevented. In the device, the main transmission is directly transmitted to the bevel gear 3 connected with the output shaft 6, the bevel gear 3 which is not connected with the input shaft 1 and the output shaft 6 has the effect of auxiliary transmission, and meanwhile, the output shaft 6 can be prevented from deviating to one side and is used for balancing moment.

The output end 5 adopts an inner hexagonal connector so as to be matched with an existing electric hand drill for use, and the output end 5 is fixedly connected with one end of the output shaft 6.

Examples

According to the above-mentioned fig. 1 to 4, the adapter used in the narrow space is made, when the user touches the inconvenient installation situation caused by the narrow space in the vertical direction, the input shaft 1 of the device is connected with the electric hand drill, the output end 5 is connected with the proper drill bit and then the alignment equipment is installed or disassembled, the input shaft 1 rotates under the action of the electric hand drill, the bevel gear 3 inside is driven to rotate, the output end 5 is driven to rotate, and the outer shell 7 does not rotate in the whole working process.

Therefore, the scope of the present invention should not be limited to the disclosure of the embodiments, but includes various alternatives and modifications without departing from the scope of the present invention, which is defined by the claims of the present patent application.
