Description

Technical Field

[0001] The utility model relates to the technical field of tape measures, in particular to a tape measure with automatic positioning of the tape. Background Art

[0002] A tape measure with automatic positioning of the tape, also known as a self-locking tape measure or an automatic locking tape measure, is an improved measuring tool mainly used in scenarios such as construction, decoration, and engineering. Compared with traditional tape measures, it has an automatic locking function, can maintain a fixed length when stretching the tape, and does not require manual pressing of the locking button, thus improving the measurement efficiency and reducing operation errors.

[0003] In current construction, decoration, and daily measurement scenarios, tape measures are widely used as basic measurement tools. Although most tape measures on the market already have the function of automatic positioning, there are still certain potential safety hazards and durability problems. For example, when the tape measure retracts quickly, since the edge of the tape is relatively sharp, if the finger of the staff accidentally stays near the telescopic opening, it is extremely easy to be scratched by the fast-moving rack, resulting in skin laceration at least and possible tendon or nerve injury at worst, seriously affecting the operation safety. In addition, the surface of the shell of some tape measures is too smooth, lacking anti-slip texture or buffer structure. When used in complex environments such as construction sites, if it accidentally falls, it is easy to damage the internal mechanical structure or cause the shell to crack due to impact with hard objects, not only shortening the service life of the tool, but also affecting the measurement accuracy due to tape jamming.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Embodiment 1:

[0029] Reference Figures 1 to 5 , which is the first embodiment of the utility model, and this embodiment provides a tape measure with automatic tape positioning, including a positioning component 5 and a mounting component 7. The present design realizes the convenient positioning function of the rack 3 through the setting of the positioning component 5. When in use, the user can directly pull out the rack 3 for measurement. When a fixed length is required, the push block 501 is pushed to drive the turntable 502 and the push plate 504 to work together through the guide plate 503, and finally the pressure ring 505 is caused to descend and firmly press on the surface of the rack 3, thereby achieving a reliable positioning effect. At the same time, the design of the mounting component 7 facilitates the rapid assembly and disassembly of the accordion protective cover 12. The accordion protective cover 12 is located on the outlet side of the rack 3 of the shell 1. When in use, it is opened, which can form an effective protection during the rapid retraction and winding process of the rack 3, avoiding the risk of cutting the operator's fingers due to the high-speed swing and its own toughness of the rack 3, and significantly improving the safety of use.

[0030] Inside the housing 1, a tape measure housing 2 is provided. At the bottom of the inner cavity of the tape measure housing 2, a rack 3 extends. On one side of the top of the housing 1, a card slot 31 is opened. On the front and rear sides of the bottom of the inner cavity of the housing 1, support plates 4 are fixedly connected. On one side of the support plate 4, a positioning component 5 is provided. On one side of the housing 1, a connecting shell 6 is fixedly connected. Inside the connecting shell 6, an installation component 7 is provided. The installation component 7 includes a spring group 701 and a second toothed plate 702.

[0031] The tape measure housing 2 and the rack 3 are existing tape measure tools. The working principles of these components are the same as those of existing tape measure tools. The tape measure housing 2 serves as the main body accommodating mechanism, with conventional components such as a winding spring provided inside. The rack 3 is used for actual measurement, and its retracting and extending mechanism is the same as that of a traditional tape measure. This is prior art, and those skilled in the art can clearly understand it, so it will not be elaborated here. The opening of the card slot 31 facilitates the subsequent cooperation of the positioning component 5 for positioning. Through the cooperation of the support plate 4, the positioning component 5 can limit and position the rack 3. The connecting shell 6 facilitates the assembly of the installation component 7, and the installation component 7 facilitates the subsequent disassembly and assembly of other components.

[0032] The positioning component 5 includes a push block 501 and a turntable 502. The push block 501 is inserted into the inside of the card slot 31. The turntable 502 is rotatably connected to one side of the support plate 4. On the front and rear sides of the bottom of the push block 501, guide plates 503 are hinged. The bottom of the inner cavity of the guide plate 503 is hinged to the turntable 502. On one side of the two turntables 502, push plates 504 are hinged. Between the bottoms of the two push plates 504, a pressing ring 505 is hinged.

[0033] First, when the user needs to release the limit on the rack 3, push the push block 501 downward to move limitedly inside the card slot 31. When the push block 501 moves, it will drive the hinged guide plate 503 to press downward. Since the guide plate 503 is hinged on the surface of the turntable 502, at this time, the turntable 502 will rotate on the support plate 4. And the push plate 504 located on the other side of the turntable 502 will also drive the hinged pressing ring 505 to rise as the turntable 502 rotates, thereby releasing the positioning of the rack 3. It should be noted that a part of both sides of the push block 501 extends out and is limited inside the card slot 31, which can limit the movement of both sides of the push block 501 to prevent it from falling off.

[0034] Embodiment Two:

[0035] This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0036] Specifically, a rubber strip 506 is fixedly connected to the bottom of the pressing ring 505. The rubber strips 506 are arranged in an array.

[0037] It is fixed to the bottom of the pressing ring 505 through an array of rubber strips 506, so as to ensure the positioning effect on the rack 3 and improve the friction force between the pressing ring 505 and the rack 3.

[0038] Specifically, sliding plates 507 are fixedly connected to both the front and rear sides of the pressing ring 505, and sliding grooves 508 for cooperating with the sliding plates 507 are provided inside the support plate 4.

[0039] By the sliding connection between the sliding plates 507 and the inside of the sliding grooves 508, the path of the up-and-down movement of the pressing ring 505 can be limited to prevent the pressing ring 505 from shaking left and right.

[0040] Specifically, an arc-shaped friction strip 8 for pressing the rack 3 is fixedly connected to one side of the inner cavity of the housing 1, and a hanging rope 9 is fixedly connected to one side of the housing 1.

[0041] The arc-shaped friction strip 8 is fixed to the bottom of the housing 1 and is located at the top of the rack 3. When the rack 3 is pressed down by the pressing ring 505, the bottom of the rack 3 will also contact the arc-shaped friction strip 8, thereby increasing the friction area, ensuring the stability of the positioning of the rack 3, and preventing it from automatically retracting.

[0042] Specifically, first buffer blocks 10 are fixedly connected to both sides of the top of the surface of the housing 1, and second buffer plates 11 are fixedly connected to both sides of the bottom of the housing 1.

[0043] By fixing the first buffer blocks 10 to both sides of the top of the housing 1 and cooperating with the arrangement of the second buffer plates 11, a certain buffering effect can be achieved when the surface of the housing 1 falls, reducing the damage to the components inside the housing 1.

[0044] Specifically, a bellows protective cover 12 is provided on one side of the housing 1. Plug blocks 13 are fixedly connected to both the front and rear sides of the bellows protective cover 12, and a plug housing 14 for cooperating with the plug blocks 13 is fixedly connected to one side of the housing 1.

[0045] By providing the bellows protective cover 12, a part of the contraction distance of the rack 3 can be protected, avoiding the risk of cutting the operator's fingers due to the high-speed swing and self-toughness of the rack 3. The insertion of the plug blocks 13 into the plug housing 14 can improve the stability of the bellows protective cover 12 installed on one side of the housing 1.

[0046] Embodiment Three:

[0047] This is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0048] Specifically, a fixing plate 15 is fixedly connected to the top of the bellows protective cover 12, and a first toothed plate 16 is fixedly connected to one side of the fixing plate 15.

[0049] By fixing the fixing plate 15 and the first toothed plate 16, it is convenient to insert the bellows protective cover 12 into the interior of the connection shell 6, and with the arrangement of the installation assembly 7, the bellows protective cover 12 can be quickly assembled and positioned.

[0050] Specifically, a guide rail 17 is fixedly connected to one side of the insertion shell 14, and a sliding strip 18 for cooperating with the guide rail 17 is fixedly connected to one side of the bellows protective cover 12.

[0051] By fixing the guide rail 17 to one side of the insertion block 13, when the bellows protective cover 12 extends, the bellows protective cover 12 will drive the sliding strip 18 to move in a limited manner inside the guide rail 17, thereby improving the stability of the bellows protective cover 12 during telescoping.

[0052] Specifically, the spring group 701 is fixed to the top of the inner cavity of the connection shell 6, and one end is fixedly connected to the second toothed plate 702. Both sides of the top of the second toothed plate 702 are fixedly connected with pull rods 703, and the tops of the pull rods 703 penetrate to the outside of the connection shell 6 and are fixedly connected with a pull plate 704.

[0053] When the user needs to assemble the first toothed plate 16, first press down the pull plate 704 to drive the pull rod 703 to move. When the pull rod 703 moves, it will drive the second toothed plate 702 to descend and compress the spring group 701. At this time, insert the first toothed plate 16 into the interior of the connection shell 6, thereby completing the positioning and installation of the bellows protective cover 12.

[0054] Specifically, a retaining plate 705 is fixedly connected to the bottom of the second toothed plate 702, and a sliding rod 706 fixedly connected to the inner wall of the connection shell 6 is slidably connected inside the retaining plate 705.

[0055] By fixing the retaining plate 705 and the second toothed plate 702, when the second toothed plate 702 is stressed and moves, the retaining plate 705 will slide in a limited manner on the surface of the sliding rod 706, thereby improving the stability of the second toothed plate 702 during movement.

[0056] Working principle: When the user needs to use the rack 3 for measurement, the rack 3 can be directly pulled to the required length. Then, when positioning is needed, the push block 501 is pushed upward to move within the card slot 31. When the push block 501 moves, it will drive the articulated guide plate 503 to press upward. The guide plate 503 is articulated on the surface of the turntable 502. At this time, the turntable 502 will rotate on the support plate 4. The push plate 504 on the other side of the turntable 502 will drive the articulated pressing ring 505 to descend as the turntable 502 rotates. At this time, the pressing ring 505 will drive the sliding plate 507 to descend within the internal limit of the sliding groove 508, thereby improving the stability of the pressing ring 505 when moving up and down. And the rubber strips 506 arranged in an array at the bottom of the pressing ring 505 are pressed against the top of the rack 3, and the arc-shaped friction strip 8 at the bottom of the rack 3 will also firmly fit on the surface of the rack 3, thus achieving the positioning effect. Then, before use, when the user needs to assemble the first tooth plate 16, first press down the pull plate 704 to drive the pull rod 703 to move. When the pull rod 703 moves, it will drive the second tooth plate 702 to descend and compress the spring group 701. At this time, the first tooth plate 16 is inserted into the internal connection shell 6, and then the second tooth plate 702 driven by the elasticity of the spring group 701 itself is clamped on the surface of the first tooth plate 16. At the same time, the bellows protective cover 12 will also drive the insertion block 13 to insert into the insertion shell 14 to achieve stable installation. Then, when the user needs to protect the outlet side of the rack 3 of the housing 1, the bellows protective cover 12 is extended to drive the sliding strip 18 to extend out within the internal limit of the guide rail 17. Then, when the rack 3 retracts, through the setting of the bellows protective cover 12, effective protection can be formed during the rapid retraction and winding process of the rack 3, avoiding the risk of cutting the operator's fingers due to the high-speed swing and its own toughness of the rack 3, and significantly improving the use safety.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
