Abstract

The utility model discloses a fastening device which comprises a bracket, a bolt, a stop dog and a metal strap, wherein one end of the metal strap is clamped on the bracket; the other end of the metal strap penetrates through a through hole at a lug part of the bracket; and the bolt penetrates through the bracket and then is in threaded fit with the stop dog at the lower end. The fastening device has a simple structure, can fasten pipelines with different sizes and temperature sensors with different sizes by the cooperation of the bolt, the stop dog and the metal strap, and has the characteristics of strong universality, high fastening intensity, convenience for disassembly and assembly and capability of achieving stepless regulation.

Description

A kind of fastener

Technical field:

The utility model relates to the operation of air conditioning systems technical field, especially relates in the operation of air conditioning systems fastener that pipeline and temperature sensor are fixed together.

Background technology:

The mode that installs and fixes of temperature sensor and pipeline mostly adopts the metal tape that has single hole or porous in the operation of air conditioning systems at present, by using bolt, nut temperature sensor and pipeline is tightened together.The fastening means of this structure need be known the diameter of temperature sensor and pipeline in advance, can implement fastening behind the punch position on definite again metal tape again, can't tackle the change in size of fastened object, there are shortcomings such as versatility is poor, fastening adjustment inconvenience, dismounting trouble, are necessary to be improved.

The utility model content:

The purpose of this utility model provides a kind of new fastener with regard to being the weak point that exists at prior art, and it has highly versatile, fastening strength height, easy accessibility and can realize the characteristics of step-less adjustment.

For achieving the above object, fastener of the present utility model includes support, bolt, block and metal tape, wherein, one end of metal tape is clamped on the support, the other end passes the perforation in the support ear, and bolt passes support, its lower end and block threaded engagement.

Preferred as technique scheme, described block comprises stop body and arc-like sheet, wherein, stop body constitutes the worm drive structure with bolt, the concave surface of arc-like sheet and temperature sensor or or pipeline applying.

Preferred as technique scheme is provided with the spacer pin that cooperates with bolt in the described stop body.

Preferred as technique scheme is the angles of 80 degree～110 degree between described support ear and the rack body.

Preferred as technique scheme is the angles of 100 degree between described support ear and the rack body.

The beneficial effects of the utility model are: it is simple in structure, by the cooperation of bolt, block and metal tape, and pipeline and temperature sensor that can fastening different size, highly versatile, fastening strength height, easy accessibility also can be realized the characteristics of step-less adjustment.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is an one-piece construction synoptic diagram of the present utility model;

Fig. 2 is the enlarged diagram of Fig. 1 medium-height trestle;

Fig. 3 is the enlarged diagram of block among Fig. 1.

Embodiment:

See that Fig. 1 is to shown in Figure 3: fastener of the present utility model includes support 10, bolt 20, block 30 and metal tape 40; Wherein, the support 10 of metal material makes clamp clip 101 fit tightly with following clamp clip 102 by the stamping-out bending to be in the same place, and a side of support 10 is formed with the support ear 11 that is 100 degree angles with support 10 main bodys; One end of metal tape 40 is clamped between clamp clip 101 and the following clamp clip 102, and the other end is walked around the perforation 111 of passing behind sensor 50 and the pipeline 60 in the support ear 11; Bolt 20 passes support 10 middle parts, its lower end and block 30 threaded engagement.

Block 30 comprises stop body 31 and the arc-like sheet 32 that welds together, wherein, stop body 31 and bolt 20 constitute the worm drive structure of left-handed or dextrorotation, the concave surface of arc-like sheet 32 and pipeline 60 applyings (be positioned at pipeline 60 upper ends as temperature sensor 50, then the concave surface of arc-like sheet 32 and temperature sensor 50 fit together).When rotating bolt 20, block 30 is up or to row, thus realize to temperature sensor 50 and pipeline 60 unclamp or fastening, but and step-less adjustment.In addition, be provided with the spacer pin 33 that cooperates with bolt 20 in the stop body 31, so that bolt 20 and stop body 31 better link together.

The above only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.
