Embodiment Construction

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0027] The invention is a screw connection device with a deep cavity mounting hole, such as Figures 1 to 3 As shown, it includes a screw mounting part 1 for temporarily accommodating screws, a first through hole 8 is provided from the front end of the screw mounting part 1 to its rear end, and the front part of the first through hole 8 is suitable for the nut shape structure of the screw Matching, that is to say, during installation, the screw cap is located at the front of the first through hole and can temporarily fix the screws to be installed through friction with the side wall of the first through hole;

[0028] The locking member 3 is provided with a second through hole 9, the rear end of the screw mounting m...

Abstract

The invention relates to a screw connecting device for an installation hole with a deep cavity. The screw connecting device comprises screw installation parts, locking parts and a screw rod. First through holes are formed in the screw installation parts from the front ends of the screw installation parts to the rear ends of the screw installation parts, and the front portions of the first through holes are matched with the shape of a nut of a screw. Second through holes are formed in the locking parts. The rear ends of the screw installation parts are located in the second through holes and are detachably connected with the locking parts in a sliding manner. The first through holes are coaxial with the second through holes. The front end of the screw rod penetrates the second through holes and penetrates in the first through holes. The screw rod is in threaded connection with the locking parts. According to the screw connecting device for the installation hole with the deep cavity, the screw can be temporarily fixed to the front ends of the screw installation parts; the screw can move back and forth along the locking parts; the screw installation parts position the installation hole in the deep cavity; the screw rod penetrates the second through holes in sequence to enter the first through holes and is in threaded connection with the locking parts. When the screw rod moves forwards, the screw at the front ends of the screw installation parts is pushed to enter the screw installation hole smoothly, and accuracy and installation efficiency of installing the screw are improved.

Description

technical field [0001] The invention relates to a screw connection device with a deep cavity installation hole, and belongs to the field of screw installation tools with a deep cavity hole. Background technique [0002] At present, the air ducts of air-cooled refrigerators are all connected by screws when installed. Since there is an enlarged cavity between the air ducts and the tank for cold air flow, the air ducts are all designed with cylindrical boss-type screw columns, such as Figure 5 Shown is a screw post with a deep cavity through which the screw is connected to the tank. Since the screw column has a deep cavity structure, it is a blind operation when screwing, and the operator cannot see the actual assembly state of the screw, which often leads to poor assembly defects such as screw deviation, crooked, and not firmly tightened. The details are as follows: Figure 6 As shown, the assembly quality of the air duct is seriously affected, resulting in a decline in the o...
