Description

TECHNICAL FIELD

[0001] The utility model relates to a timer, in particular to a timer with pauseable movement. BACKGROUND

[0002] The movement of a timer is divided into a quartz clock type movement and a mechanical movement, the main structure of the mechanical movement includes a mainspring as a power source, a gear set for transmitting the power of the mainspring, and an escapement mechanism (including an escapement lever, an escapement wheel, a balance wheel and a hairspring) for controlling the slow release of the power of the mainspring, see the utility model patent with the publication number CN201716526U, the application date of July 14, 2010, and the name of a novel timer movement.

[0003] The mechanical movement has the advantages of simple structure, reliable operation and low cost, but the function of the mechanical movement is relatively single, after setting the timing time (winding the mainspring), the timer will always work until reaching the 0 scale. In actual use, the consumer also hopes that the timer made of such a movement has more functions, for example, when other matters need to be handled urgently during the timing process, the consumer can temporarily stop the timing, and after the matters are handled, the timing is continued, that is, the timing pause function. SUMMARY

[0004] The utility model aims at overcoming the defects in the above background technology, and provides a timer with pause function, which has the characteristics of pauseable countdown time and convenient use.

[0005] The technical scheme of the utility model is:

[0006] A timer with pauseable movement, comprising a bottom shell with a movement and a rotating cover connected with the movement, characterized in that it further comprises a switch arranged on the rotating cover, a clamping mechanism capable of clamping the escapement mechanism of the movement under the push of the switch to pause the timing, and a limiting mechanism for keeping the switch in the pause position; the movement is inverted in the bottom shell.

[0007] The rotating shaft of the movement is fixed with the bottom shell, and the bottom surface of the movement is fixed with the rotating cover.

[0008] The switch is swingably positioned on the rotating cover; the clamping mechanism is arranged on the rotating cover and located above the escapement mechanism of the movement.

[0009] The clamping mechanism comprises a pressing block vertically slidably positioned on the rotating cover, a spring for upwardly pushing the pressing block, and a clamping needle fixed with the pressing block and downwardly extending into the movement.

[0010] The bottom surface of the switch is provided with a protruding part for extruding the pressing block.

[0011] The rotating cover top surface is provided with a mounting seat, a sliding groove for guiding the sliding of a pressing block and a pin hole matched with a clamping pin are arranged in the mounting seat.

[0012] The limiting mechanism comprises a groove and a convex rib arranged between the switch and the rotating cover.

[0013] The beneficial effects of the present application are as follows:

[0014] The present application inverts the internal movement, and adds a switch, a clamping mechanism and a limiting mechanism. When the switch on one side is pressed, the clamping mechanism and the limiting mechanism prevent the escapement mechanism of the movement from moving, so that the timing is paused. When the switch on the other side is pressed, the timing continues. Therefore, the present application realizes the function of pausing the timing of the mechanical movement, and meets the needs of consumers. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0025] AsFigure 1 As shown, a timer with a pauseable movement includes a base case 1, a movement 2, and a rotating cover 3. The movement is housed in the base case, and the rotating cover is connected to the movement. In use, the rotating cover is first rotated one full turn to wind the mainspring of the movement, and then the rotating cover is rotated to the timing position to start the countdown. When the countdown ends, the movement rings an alarm.

[0026] The above structure is the same as the existing technology. The improvement of this utility model is that the movement is placed upside down in the bottom shell, and a switch 4, a locking mechanism and a limiting mechanism are added.

[0027] The movement's pivot has a top surface on one side and a bottom surface on the other. Since the movement is inverted within the case back, the pivot is vertically downwards and fixed to the center of the bottom surface of the case back. The cover, located above the case back, is fixed to the bottom surface of the movement. The outer circumference of the cover has a graduation ring, and the outer circumference of the case back has an indicator arrow.

[0028] The reason for using an inverted movement is that, due to the limitations of the existing movement structure, if the locking pin extends into the movement from the top surface, it will be blocked by parts and will not be able to hold the escapement mechanism in place. However, if the locking pin extends into the movement from the bottom surface, it can successfully hold the escapement mechanism in place.

[0029] The switch can be positioned on the rotating cover by swinging left and right. For example... Figure 5 As shown, the top surface of the rotating cover is provided with a pair of support seats 3-5, and the support seats have shaft holes. Figure 6 As shown, the bottom surface of the switch is provided with a pair of support shafts 4-3 that can be inserted into shaft holes to form a rotational fit.

[0030] The top surface of the rotating cover is a concave platform, lower in the middle and higher around the edges. For example... Figure 3 As shown, when the timer is in either the stopped or counting state, the switch is positioned with the left side higher than the right, the left side of the switch tilting upwards and above the top surface of the rotating cover, while the right side of the switch is flush with the top surface of the rotating cover. Figure 4 As shown, the timer is in the paused state, the switch is lower on the left and higher on the right, the left side of the switch is flush with the top surface of the cover, and the right side of the switch is tilted upward and higher than the top surface of the cover.

[0031] The locking mechanism is mounted on the cover and located above the escapement mechanism of the movement. In the locking mechanism, the top surface of the cover has a mounting base 3-1 with a vertically extending groove 3-2. A pressure block 5 is vertically slidably positioned in the groove. The bottom surface of the groove has a pinhole 3-3 penetrating the cover (the bottom surface of the movement also has openings corresponding to the pinhole). A spring 6 is located below the pressure block. A downwardly extending locking pin 7 is located at the center of the bottom surface of the pressure block. The locking pin passes downward through the pinhole and extends into the movement, positioned above the escapement mechanism. The locking pin is made of plastic, ensuring that when it descends and contacts the escapement mechanism, it does not damage the escapement mechanism and prevents its movement. The bottom surface of the switch has a protrusion 4-1 that presses against the pressure block.

[0032] The locking pin can be positioned above the escape fork, escape wheel, or balance wheel of the escape mechanism, depending on the specific requirements. When the locking pin descends, it will contact the escape fork, escape wheel, or balance wheel of the escape mechanism, thereby preventing the escape mechanism from moving and causing the movement to stop working.

[0033] like Figure 7 As shown, the locking pin is positioned above the balance wheel 2-1, which stops the movement by preventing the balance wheel from moving.

[0034] The limiting mechanism is used to hold the switch in the paused position. The limiting mechanism includes a groove 4-2 and a rib 3-4 disposed between the switch and the rotating cover. Figure 3 As shown, the groove is formed on the left side of the outer circumference of the switch, and the rib is formed on the left side of the inner circumference of the rotating cover recess. When the timer is in the stop or timing state, the groove is located above the rib. When the timer is in the pause state, the rib is embedded in the groove (a certain amount of external force needs to be applied to make the groove detach from the rib).

[0035] The working principle of this utility model is as follows:

[0036] 1. For example Figure 3 As shown, under the action of the spring, the switch remains on the left side and springs upward, the locking pin does not contact the balance wheel of the movement, and the timer is in the stopped state or the normal timing state.

[0037] 2. For example Figure 4 As shown, if it is necessary to pause the movement, press the left side of the switch so that the groove of the switch engages with the rib of the cover. After the pressure block is squeezed by the protrusion, it drives the locking pin to descend and contact the balance wheel. Since the balance wheel is blocked by the locking pin and cannot swing, the escape fork blocks the escape wheel from rotating, and the movement stops working.

[0038] 3. If you need to continue timing, press the right side of the switch. The groove will disengage from the rib, and the spring will push the pressure block to rise, keeping the switch on the left side. Since the locking pin rises and no longer contacts the balance wheel, the movement will start working and the timing will continue.

[0039] The preferred embodiments of the present application are illustrated in the attached drawings. The present application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth in the specification. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art.
