Abstract
Belonging to the technical field of a calculagraph, a projection clock is designed to stabilize a projection drawing in a chosen position. The utility model includes a clock, the clock hands (22) and diaphanous letter side (21) of the clock are placed in a light path which is started by an electric light source (5) and includes a magnifier; one part of the light path, the clock hands (22) and diaphanous letter side (21) are all installed in a circular tube (3) which is nested in the circular hole of a base seat (1). A damped structure is arranged between the circular tube (3) and the circular hole. In the damped structure, the base seat (1) is provided with a through screw hole (16) corresponding to the circular tube (3), a spring (13) placed in the through screw hole (16) is clung to the outer wall of the circular tube (3), a bolt (130) matches with the internal thread of the screw hole, and the spring (13) is compressed between the bolt (130) and the outer wall of the circular tube (3).
Description
Technical field
The utility model belongs to the timer technical field, relates in particular to the projection clock.
Background technology
The general structure of projection clock comprises a clock, the time hand of a clock and printing opacity literal be placed in one initial and comprise in the light path of magnifier with electric light source, thereby on a projection carrier (such as metope), project one by pointer and the literal perspective view that overlaps of printing opacity, and show the time whereby.The part of light path and the time hand of a clock and printing opacity is literal all is installed in the pipe, pipe is sleeved in the circular hole on the pedestal; Like this, rotate pipe, just can change the direction of projection, promptly in the different position display time with respect to pedestal.Its defective often is because pipe is lax with cooperating of circular hole, perspective view is produced rock even swing.
Summary of the invention
In order to make perspective view be stabilized in selected position, the utility model provides a kind of projection clock.
The technical solution of the utility model is: add damping structure between the cooperating of circular hole on pipe and pedestal.That is:
A kind of projection clock, comprise a clock, the time hand of a clock and printing opacity literal be placed in one initial and comprise in the light path of magnifier with electric light source, the part of light path and the time hand of a clock and printing opacity is literal all is installed in the pipe, pipe is sleeved in the circular hole on the pedestal; It is characterized in that: damping structure is arranged between the cooperating of pipe and circular hole.
The utility model characteristics: because the said structure feature, perspective view then of the present utility model just can be stabilized in selected position, thereby has reached goal of the invention.
Description of drawings
Below in conjunction with embodiment the utility model is illustrated:
Fig. 1 is a synoptic diagram of the present utility model.
Embodiment
As shown in the figure, a kind of projection clock, comprise a clock, the time hand of a clock 22 and printing opacity literal 21 be placed in one initial and comprise in the light path of magnifier (not shown) with electric light source 5, the part of light path and the time hand of a clock 22 and printing opacity literal 21 all be installed in the pipe 3, pipe 3 is sleeved in the circular hole of pedestal 1; It is characterized in that: damping structure is arranged between the cooperating of pipe 3 and circular hole.
As shown in the figure, described damping structure is: corresponding pipe 3 is provided with a penetrating screw 16 on pedestal 1, spring 13 is placed on the outer wall that is adjacent to pipe 3 in this penetrating screw 16, the screw-internal thread fit of screw 130 and screw, and spring 13 is compressed between the outer wall of screw 130 and pipe 3.
Same as the prior art, as shown in the figure, a reflective mirror 4 is arranged within the pipe 3; Screw 14 penetrates pedestal 1 and pipe 3 is connected reflective mirror 4 and pedestal 1.Pipe 3 is strip holes corresponding to the position of screw 14, so that pipe 3 can be done the adjustment at relative phase angle with respect to pedestal 1.
Same as the prior art, as shown in the figure, (be nested with one by one three) needle shaft 23 of clock stretches out from movement 20, and it is literal 21 to penetrate reflective mirror 4 and printing opacity, and pointer 22 is packed on the needle shaft 23.
Same as the prior art, as shown in the figure, face electric light source 5 on the pedestal 1 and be fixed with fan 6, in order to cooling.Because electric light source 5 is generally shot-light, bigger heating is arranged.
Same as the prior art, not shown, pipe 3 has an extension, and the another one reflective mirror is arranged in this extension, is fixed with convex lens (magnifier) on this extension.
Same as the prior art, not shown, there are a ventilative rain cover and pedestal 1 to install.Should ventilative rain cover only detain and overlay on the structure shown in Figure 1, be not overlying on the described pipe 3 of epimere and have on the extension and do not detain.
Claims (2)
1. projection clock, comprise a clock, the time hand of a clock (22) and printing opacity literal (21) be placed in one initial and comprise in the light path of magnifier with electric light source (5), the part of light path and the time hand of a clock (22) and printing opacity literal (21) all be installed in the pipe (3), pipe (3) is sleeved in the circular hole of pedestal (1); It is characterized in that: damping structure is arranged between the cooperating of pipe (3) and circular hole.
2. a kind of projection clock according to claim 1, it is characterized in that described damping structure is: go up corresponding pipe (3) at pedestal (1) and be provided with a penetrating screw (16), spring (13) is placed on the outer wall that is adjacent to pipe (3) in the penetrating screw (16), the screw-internal thread fit of screw (130) and screw, spring (13) is compressed between the outer wall of screw (130) and pipe (3).
