Description

Technical Field

[0001] This utility model relates to the field of measuring tools, and in particular to a measuring tape. Background Technology

[0002] A measuring tape is a common measuring tool used to measure dimensions such as length, width, and height. Because it has an internal telescopic spring, the tape retracts automatically after measurement, causing the tape strip to shrink back into the casing. However, the tape strip retracts relatively quickly during this process, which could cause it to flip upwards at the tape's opening, potentially causing injury. This poses a safety risk. Utility Model Content

[0003] The purpose of this utility model is to provide a measuring tape that can prevent the measuring tape from flipping up when the tape retracts into the casing, thereby improving safety during use.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Measuring tape, including:

[0006] A ruler assembly and a ruler housing, wherein the ruler assembly is disposed within the ruler housing;

[0007] The ruler assembly includes a measuring tape, a roller, and a return spring. The measuring tape is wound around the roller, and the return spring is disposed on the roller and connected to the measuring tape.

[0008] A measuring opening is provided on one side of the ruler housing, and one end of the measuring tape extends out of the ruler housing through the measuring opening;

[0009] In this design, from left to right, the measuring opening is inclined away from the bottom wall of the ruler shell, so that an anti-tipping part is formed above the measuring opening.

[0010] As a further technical solution, the measuring tape also includes a constraint component, which is disposed inside the tape casing. The constraint component includes an upper constraint plate, which is disposed above the measuring tape strip and extends toward the measuring tape strip.

[0011] As a further technical solution, the side of the upper constraint plate near the measuring tape is configured as a first arc-shaped surface, and the cross-sectional shape of the first arc-shaped surface is adapted to the upper sidewall of the measuring tape.

[0012] As a further technical solution, the constraint assembly also includes a lower constraint plate disposed opposite to the upper constraint plate. The lower constraint plate is disposed on the bottom wall of the ruler shell, and the upper constraint plate and the lower constraint plate cooperate to form a constraint channel that allows the measuring tape to pass through.

[0013] As a further technical solution, the upper constraint plate is configured with a second arc-shaped surface on the side near the measuring tape, and the cross-sectional shape of the second arc-shaped surface is adapted to the lower sidewall of the measuring tape.

[0014] As a further technical solution, the measuring tape also includes a buffer assembly, which is disposed below the measuring opening.

[0015] As a further technical solution, the buffer assembly includes a flexible buffer block, which is connected to the bottom wall of the ruler shell.

[0016] As a further technical solution, the buffer assembly includes a shock-absorbing block and a buffer spring, wherein the shock-absorbing block is connected to the bottom wall of the ruler shell through the buffer spring.

[0017] As a further technical solution, the measuring tape also includes a leveling component, which includes an annular bubble level, and the annular bubble level is disposed on the first or second side wall of the measuring tape casing.

[0018] As a further technical solution, the leveling component also includes an annular scale, which is disposed on the ruler shell corresponding to the annular bubble level.

[0019] Compared with the prior art, the measuring tape provided by this utility model has the following technical advantages:

[0020] Because the measuring opening is tilted away from the bottom wall of the measuring tape casing from left to right, an anti-tipping section is formed above the measuring opening. Therefore, when the measuring tape is finished using, as the tape retracts into the casing under the action of the return spring, the anti-tipping section can surround the tape, thereby preventing the tape from flipping up and improving safety during use.

[0033] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0034] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0035] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0036] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0037] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0038] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0039] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0040] Combination Figures 1 to 4As shown, the measuring tape provided in this embodiment can prevent the measuring tape 100 from flipping up when it retracts into the casing 200, thereby improving safety. Specifically, the measuring tape includes a tape assembly and a casing 100, with the tape assembly disposed within the casing 200. The tape assembly includes the measuring tape 100, a roller, and a return spring. The measuring tape 100 is wound around the roller, and the return spring is disposed on the roller and connected to the measuring tape 100. A measuring opening 201 is provided on one side of the casing 200, and one end of the measuring tape 100 extends out of the casing 200 through the measuring opening 201. From left to right, the measuring opening 201 is inclined away from the bottom wall 240 of the casing 100, forming an anti-flipping portion above the measuring opening 201.

[0041] Because the measuring opening 201 is inclined away from the bottom wall 240 in the casing 100 from left to right, an anti-tipping part is formed above the measuring opening 201. Therefore, when the measuring tape is used up and the tape 100 retracts into the casing 200 under the action of the return spring, the anti-tipping part can surround the tape 100, thereby preventing the tape 100 from tipping over and improving safety during use.

[0042] Preferably, the measuring tape further includes a constraint component 400, which is disposed within the casing 200. The constraint component 400 includes an upper constraint plate 410, which is disposed above the measuring tape strip 100 and extends toward the measuring tape strip 100.

[0043] Because the measuring opening 201 is inclined away from the bottom wall 240 of the casing 100 from left to right, an anti-tipping portion is formed above the measuring opening 201. This increases the distance between the measuring opening 201 and the scroll, thereby limiting the path of the measuring tape 100 extending out of or retracting into the casing 200 by setting a constraint component 400 between the measuring opening 201 and the scroll, preventing bending of the measuring tape 100 between the measuring opening 201 and the scroll, and ensuring the effectiveness of the measuring tape. Specifically, the upper constraint plate 410 is connected to the first side wall 220 or the second side wall 230. By setting the upper constraint plate 410, the space for the measuring tape 100 to swing up and down when extending out of or retracting into the casing 200 is reduced.

[0044] Furthermore, the side of the upper constraint plate 410 near the measuring tape 100 is configured as a first arc-shaped surface, the cross-sectional shape of which is adapted to the upper sidewall of the measuring tape 100. During the process of the measuring tape 100 extending out of the measuring housing 200 or retracting into the measuring housing 200, the arc surface of the first arc-shaped surface cooperates with the upper sidewall of the measuring tape 100, further reducing the space for the measuring tape 100 to swing up and down, thereby ensuring the stability of the measuring tape 100 when extending out of the measuring housing 200 or retracting into the measuring housing 200, and preventing damage to the upper sidewall of the measuring tape 100 caused by the end face of the upper constraint plate 410 near the measuring tape 100.

[0045] Furthermore, the constraint assembly 400 also includes a lower constraint plate 420 disposed opposite to the upper constraint plate 410. The lower constraint plate 420 is disposed on the bottom wall 240 of the ruler housing 200, and the upper constraint plate 410 and the lower constraint plate 420 cooperate to form a constraint channel that allows the measuring tape 100 to pass through. The lower constraint plate 420 is fixedly connected to the inside of the bottom wall 240 and extends in a direction away from the bottom wall 240. Both the upper constraint plate 410 and the lower constraint plate 420 are perpendicular to the bottom wall 240. The constraint channel formed by the cooperation of the upper constraint plate 410 and the lower constraint plate 420 further reduces the space for the measuring tape 100 to swing up and down when it extends out of the ruler housing 200 or retracts into the ruler housing 200.

[0046] Preferably, the side of the upper constraint plate 410 near the measuring tape 100 is provided with a second arc-shaped surface, and the cross-sectional shape of the second arc-shaped surface is adapted to the lower sidewall of the measuring tape 100. During the process of the measuring tape 100 extending out of the measuring housing 200 or retracting into the measuring housing 200, the arc surface of the second arc-shaped surface cooperates with the lower sidewall of the measuring tape 100, further reducing the space for the measuring tape 100 to swing up and down, thereby ensuring the stability of the measuring tape 100 when extending out of the measuring housing 200 or retracting into the measuring housing 200, and preventing damage to the lower sidewall of the measuring tape 100 caused by the end face of the lower constraint plate 420 near the measuring tape 100.

[0047] The number of upper constraint plates 410 and lower constraint plates 420 in constraint component 400 can be the same or different. The specific number and position can be adjusted according to actual needs, and no specific restrictions are imposed here.

[0048] Preferably, the measuring tape further includes a buffer assembly 500, which is disposed on the casing 200 corresponding to the measuring opening 201 and located below the measuring opening 201.

[0049] Combination Figures 1 to 4As shown, a check element 110 is provided at the end of the measuring tape 100 that extends out of the measuring opening 201. The check element 110 is set at an angle to the measuring tape 100. When the measuring tape is used up, the measuring tape 100 retracts into the tape housing 200 under the action of the return spring. The check element 110 abuts against the bottom wall 240 of the tape housing 200 to prevent the measuring tape 100 from completely retracting into the tape housing 200 and affecting the next use. However, because the measuring tape 100 retracts at a relatively fast speed, the impact force on the bottom wall 240 and the tape housing 200 is relatively large when the check element 110 abuts against the bottom wall 240 of the tape housing 200. By providing a buffer component 500, the impact force between the check element 110 and the tape housing 200 during the retraction of the measuring tape 100 can be buffered, thereby extending the service life of the measuring tape 100 and the tape housing 200.

[0050] Specifically, the buffer assembly 500 includes a flexible buffer block 510, which is fixedly connected to the bottom wall 240 of the housing 200. The material of the flexible buffer block 510 can be selected according to actual needs, such as polyurethane foam, silicone foam, EPDM rubber foam, etc., to buffer the impact force between the anti-rebound element 110 and the housing 200 through the elasticity and resilience of the material itself.

[0051] Alternatively, the cushioning assembly 500 includes a shock absorber 520 and a cushioning spring 530, with the shock absorber 520 connected to the bottom wall 240 of the housing 200 via the cushioning spring 530.

[0052] Combination Figure 2 As shown, during the retraction of the tape measure 100, when the check element 110 contacts the damping block 520, the impact force is transmitted through the damping block 520 to the compression spring. The buffer spring 530 is compressed by the impact force. During the compression of the buffer spring 530, the impact force between the check element 110 and the tape measure 200 can be buffered.

[0053] In other embodiments, flexible material may be covered or bonded to the end face of the damping block 520 near the check member 110, or to the side of the check member 110 near the damping block 520, to further improve the cushioning effect.

[0054] Preferably, the measuring tape further includes a leveling component 600, which includes an annular level bubble 610 disposed on the first sidewall 220 or the second sidewall 230 of the measuring tape housing 200.

[0055] The annular bubble level 610 can be provided only on the first sidewall 220, only on the second sidewall 230, or on both the first sidewall 220 and the second sidewall 230; in this embodiment, the annular bubble level 610 is provided on the first sidewall 220. In the frontal view, the bottom wall 240 of the measuring tape is in a horizontal position.

[0056] The annular level bubble 610 consists of an annular measuring tube and a measuring liquid. The measuring liquid is filled inside the annular measuring tube, and its volume occupies half of the inner cavity of the annular measuring tube. The annular measuring tube is a sealed tube. Place the bottom wall 240 of the measuring tape on the surface to be measured. If the liquid levels on both sides of the annular measuring tube are at the same level, the surface to be measured is horizontal. If the liquid levels on both sides of the annular measuring tube are not at the same level, the surface to be measured is tilted. Adjust the surface to be measured until the liquid levels on both sides of the annular measuring tube are at the same level.

[0057] To further improve the convenience and accuracy of understanding the tilt of the surface being measured during the measurement process, in this embodiment, the leveling component 600 also includes an annular scale 620, which is correspondingly set on the ruler housing 200 along with the annular bubble level 610. The annular scale 620 can be located inside or outside the annular bubble level 610, or the annular measuring tube can be made transparent with the annular scale 620 set on the annular bubble level 610. The specific setting method is selected according to actual needs and is not specifically limited here. During the use of the measuring tape, the tilt of the surface being measured is accurately determined by comparing the liquid levels on both sides of the annular bubble level 610 with the annular scale 620, facilitating adaptive adjustments to the surface.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
