Description
Technical Field
The utility model relates to a clamp, in particular to a clamp with good pre-tightening effect.
Background
The clamp is a connecting device for connecting pipe fittings, valves and pipeline fittings with grooves, and is used for playing a role of tightening connection between quick connectors.
The common clamp has narrower width of the tightening section, and can achieve good tightening effect during installation, but can generate loosening phenomenon during long-time use, and particularly has general tightening effect when the pipe fitting and the accessory to be connected are in a complex environment such as vibration.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model aims to provide a clamp with good pre-tightening effect.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
The clamp with good pre-tightening effect comprises an upper half clamp body, a lower half clamp body and a locking section, wherein the upper half clamp body and the lower half clamp body are connected in a rotating mode, the locking section is positioned at the tail end of the half clamp body and is matched and meshed, metal pressing pieces extending outwards are arranged at the left side edge and the right side edge of the inner wall of the half clamp body, and the tail ends of the metal pressing pieces are inwards bent to form grooves; rubber pads are arranged between the left groove and the right groove.
Preferably: the included angle between the metal pressing sheet and the extension line of the inner wall of the half hoop body is an acute angle.
Preferably: the included angle between the metal pressing sheet and the extension line of the inner wall of the half hoop body is 15-30 degrees.
Preferably: the outer side face of the bending section at the tail end of the metal pressing sheet is provided with a plurality of concave points.
Preferably: the inner side surface of the extending section of the metal pressing sheet is provided with a plurality of salient points.
According to the utility model, the metal pressing sheets are added on the two sides of the inner wall of the half hoop body of the hoop, so that the tightening surface of the hoop is greatly increased, namely the stress area is increased, and the installation effect is improved. Through the contained angle design of metal preforming and half clamp inner wall extension line, metal preforming extrudees the rubber pad downwards when the installation, and metal preforming extends to both sides and produce micro deformation, and the rubber pad takes place micro deformation in the slot thereupon, produces pretightning force. The extrusion force of bump and the adsorption force of concave point in the deformation process can increase local friction, prevent the whole slip of clamp, improve the installation effect.

FIG. 1 is a schematic diagram of the overall structure of a clip;
Fig. 2 is a schematic cross-sectional view of a half hoop.
In the figure: 1. metal tabletting; 2. a groove; 3. a rubber pad; 4. pits; 5. a bump; 6. a half hoop body; 7. locking the segment.
Detailed Description
The structure of the present utility model will now be fully described in connection with the specific embodiments so that those skilled in the art will fully understand and practice the utility model.
As shown in fig. 1 and 2, the clamp with good pre-tightening effect comprises an upper half clamp body 6, a lower half clamp body 6 and a locking section 7, wherein the upper half clamp body and the lower half clamp body are connected in a rotating way, and the locking section 7 is positioned at the tail end of the half clamp body 6 and is matched and meshed with the half clamp body, and the clamp is characterized in that metal pressing sheets 1 extending outwards are arranged at the left side edge and the right side edge of the inner wall of the half clamp body 6, and the tail ends of the metal pressing sheets 1 are inwards bent to form grooves 2; rubber pads 3 are arranged between the left groove 2 and the right groove 2.
Further set up: the included angle between the metal pressing sheet 1 and the extension line of the inner wall of the half hoop body 6 is an acute angle; preferably, the included angle between the metal pressing sheet 1 and the extension line of the inner wall of the half hoop body 6 is θ=15° to 30 °. When the clamp is installed, the metal pressing sheet 1 presses towards a pipe fitting/fitting to be installed along with external force, the metal pressing sheet 1 and the extension line included angle of the inner wall of the half-hoop body 6 enable the metal pressing sheet 1 to have deformation space, namely extend towards two sides, meanwhile, the rubber pad 3 is enabled to extend and deform through pressing, namely the rubber pad 3 generates shrinkage pretightening force, and the installation effect is improved. The extended metal sheeting 1 further increases the overall footprint of the half hoop 6, improving installation effectiveness.
Further set up: the outer side surface of the bending section at the tail end of the metal pressing sheet 1 is provided with a plurality of concave points 4; the inner side surface of the extension section of the metal pressing sheet 1 is provided with a plurality of salient points 5. With the extension of the metal pressing sheet 1, the salient points 5 downwards squeeze the rubber pad 3, so that the local friction force of the rubber pad 3 is greatly increased, and the anti-skid effect is improved; the concave points 4 are clung to the pipe fittings/accessories to be assembled, so that the anti-skid effect is improved.
The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model or modifications to equivalent embodiments using the above disclosed method without departing from the technical principle and scope of the solution of the present utility model. Therefore, any combination, modification or substitution of the technical features disclosed in the present utility model according to the technical substance of the present utility model should be within the protection scope of the technical solution of the present utility model, wherever the principle or the solution of the present utility model is not deviated.
