Abstract

The utility model discloses a tape pulling device which comprises a shell body made of spring steel, a rolling-up wheel and a pulling tape, wherein the pulling tape is wound on the rolling-up wheel. One end of the pulling tape is fixedly connected with a drawing end outside the shell body, and the other end of the pulling tape is fixedly connected with the rolling-up wheel. The shell body is of a barrel shape. The shell body is fixedly connected with a fixing plate. A cross section of the fixing plate is of a W shape. The middle portion of the fixing plate is attached to the side surface of the shell body to form an arc surface which is matched with the side surface of the shell body. A center line of the arc surface is parallel to an axle wire of the shell body. Two wings of the fixing plate are symmetrical with the center line of the arc surface as a symmetrical axis. A plane of the two wings of the fixing plate is parallel to a tangency face of a cambered surface where the center line of the arc surface is placed, and protrudes out of the tangency face of the cambered surface in the direction of deviating from one side of the shell body. Positioning holes are arranged on the plane of the two wings. The tape pulling device is simple in structure, and the stability and fastening of a tensioner on an installing face are effectively guaranteed.

Description

Draw the volume device

Technical field

The utility model relates to advertisement exhibition apparatus field, is specifically related to a kind of volume device that draws.

Background technology

Drawing the volume device is device commonly used in the advertisement isolation guard rail.Winding is drawn in its inner rolling, will draw winding to pull out the formation area of isolation during use from draw the volume device, and the rolling power in the complete post-tensioning volume device automatically will be drawn winding to regain and be drawn in the volume device.

Draw on the volume device and be provided with adapter plate, be provided with knock hole on the adapter plate.When the volume device is drawn in use locating plate is installed on the plane of wish applying, fixedly draws the volume device by hammering into screw in the knock hole.But traditional locating plate is the plane, when the metope of surface irregularity or other irregular attachment faces use, because attachment face rises and falls and causes locating plate not fit tightly with attachment face to cause drawing the volume device to be installed unstablely easily dropping.

The utility model content

For solving the problems of the technologies described above, we have proposed a kind of volume device that draws, and its objective is, providing a kind of can install at the attachment face of irregular wall or other fluctuatings, is difficult for dropping so that stretcher can fit tightly to guarantee to install to stablize.

For achieving the above object, the technical solution of the utility model is as follows:

Draw the volume device, it comprises the housing of being made by spring steel, be arranged at the winding wheel in the housing and draw winding, describedly draw the winding rolling on winding wheel, draw the end stretching end outer with placing housing of winding to captive joint, draw the other end of winding to captive joint with winding wheel, described housing is tubular, be fixedly connected with adapter plate on the housing, the cross-sectional plane of described adapter plate is W shape, the adapter plate middle part fits with the case side surface and forms the arc surface that matches with the case side surface, the line of centers of arc surface parallels with the axis of housing, the both wings of adapter plate and arc surface line of centers are symmetrical, and described adapter plate both wings plane parallels with the phase tangent plane of the cambered surface at the line of centers place of arc surface and to deviating from the phase tangent plane that protrudes from described cambered surface on a side direction of housing, described both wings are provided with knock hole on the plane.

Cross technique scheme, the beneficial effect that the utility model is obtained is: locating plate is arranged to W shape shape, the adapter plate middle part fits with the case side surface and forms the arc surface that matches with the case side surface, it is tangent towards parallel parallel faces with arc surface that both wings form, and the both wings plane parallels with the phase tangent plane of the cambered surface at the line of centers place of arc surface and to deviating from the phase tangent plane that protrudes from described cambered surface on a side direction of housing.Form the dead slot of certain space between the both wings of adapter plate and the arc surface of housing, have when protrusion relief part can be installed among this dead slot running into attachment face like this, and that both wings and smooth part are fitted is fixing, guaranteed to draw the installation of volume device stable.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Below in conjunction with embodiment and the specific embodiment the utility model is described in further detail.

The present embodiment as depicted in figs. 1 and 2, it comprises the housing 1 of being made by spring steel to draw the volume device, be arranged at the winding wheel 2 in the housing 1 and draw winding 3, describedly draw winding 3 rollings on winding wheel 2, draw an end of winding 3 to hold 4 to captive joint with the stretching outside placing housing 1, draw the other end of winding 3 to captive joint with winding wheel 2, described housing 1 is tubular, be fixedly connected with adapter plate 5 on the housing 1, the cross-sectional plane of described adapter plate 5 is W shape, adapter plate 5 middle parts and housing 1 side surface fit and form the arc surface that matches with housing 1 side surface, the line of centers of arc surface parallels with the axis of housing 1, the both wings of adapter plate 5 and arc surface line of centers are symmetrical, described adapter plate 5 both wings planes parallel with the phase tangent plane of the cambered surface at the line of centers place of arc surface and to deviating from the phase tangent plane that protrudes from described cambered surface on a side direction of housing 1, described both wings are provided with knock hole 6 on the plane.

Locating plate is arranged to W shape shape, the adapter plate middle part fits with the case side surface and forms the arc surface that matches with the case side surface, it is tangent towards parallel parallel faces with arc surface that both wings form, and the both wings plane parallels with the phase tangent plane of the cambered surface at the line of centers place of arc surface and to deviating from the phase tangent plane that protrudes from described cambered surface on a side direction of housing.Form the dead slot of certain space between the both wings of adapter plate and the arc surface of housing, have when protrusion relief part can be installed among this dead slot running into attachment face like this, and that both wings and smooth part are fitted is fixing, guaranteed to draw the installation of volume device stable.
