Description

Technical Field

[0001] The utility model relates to the technical field of measuring tapes, in particular to a two-in-one measuring tape. Background Art

[0002] Most of the tape measures currently on the market include a shell with a winding device inside the shell for winding up the measuring tape. When it is necessary to measure the length of an object, the user only needs to pull one end of the measuring tape to pull the measuring tape out of the shell. When the measurement is completed, the measuring tape is released and the winding device will retract the measuring tape into the shell. Since the winding device has a fast winding speed and both ends of the measuring tape are sharp, the user's palm is easily scratched when the measuring tape is rolled up. Utility Model Content

[0003] The utility model provides a two-in-one measuring tape, which can overcome certain defects of the prior art.

[0004] According to the utility model, a two-in-one measuring tape comprises a shell, a mounting cavity is arranged inside the shell, and an opening communicating with the mounting cavity is arranged at the side wall at the lower end of the shell; a winding belt and a measuring ruler with one end connected to the winding belt and the other end extending into the opening are arranged in the mounting cavity; a deceleration mechanism is arranged near the opening in the mounting cavity, and the deceleration mechanism is used to decelerate the speed at which the winding belt retracts the measuring ruler.

[0005] With the utility model, when the object to be measured is long, the user pulls the measuring ruler out of the installation cavity for measurement. After the measurement is completed, the measuring ruler is released, and the winding belt pulls the measuring ruler back into the installation cavity. During this process, the deceleration mechanism reduces the speed at which the measuring ruler enters the installation cavity, thereby preventing the measuring ruler from scratching the palm or arm of the user due to the winding belt being wound up too quickly.

[0006] Preferably, the mitigation mechanism comprises columns arranged on both sides of the measuring scale, a sleeve is sleeved on the column, a clamping plate extending toward the measuring scale is provided on the side wall of the sleeve, and a spring is provided between the clamping plate and the inner side wall of the installation cavity for pushing the clamping plate toward the measuring scale.

[0007] With the utility model, when the winding belt retracts the measuring ruler into the installation cavity, the spring pushes the clamping plate, thereby causing the sleeve to rotate along the column, and finally causing the clamping plate to squeeze the measuring ruler. The friction between the clamping plate and the measuring ruler slows down the speed at which the measuring ruler enters the installation cavity, thereby preventing the user from being injured due to the measuring ruler being retracted too quickly by the winding belt.

[0008] Preferably, a sponge plate is provided on one end surface of the clamping plate close to the measuring ruler.

[0009] With the utility model, the sponge plate contacts the measuring ruler and deforms when the clamping plate is pushed by the spring, so that the measuring ruler is prevented from being damaged when the clamping plate squeezes the measuring ruler, thereby extending the service life of the measuring ruler.

[0010] Preferably, a support plate for supporting a measuring ruler is provided at the lower end of the clamping plate.

[0011] With the utility model, when the measuring ruler enters and exits the opening, the support plate props up the measuring ruler, so that the measuring ruler is more stable when moving. At the same time, the support plate contacts the lower end surface of the measuring ruler, increasing the contact area between the measuring ruler and the support plate, thereby increasing the friction between the measuring ruler and the support plate, and slowing down the speed of the measuring ruler when it is recovered; the support plate is located below the measuring ruler, thereby avoiding contact with the scale lines on the measuring ruler, preventing the scale lines from being damaged due to wear.

[0012] Preferably, a blind hole for the spring to extend into is provided on the inner side wall of the installation cavity.

[0013] With the utility model, the installer inserts one end of the spring into the blind hole and the other end abuts against the clamping plate, thereby preventing the spring from being displaced when being squeezed by the clamping plate.

[0014] Preferably, an L-shaped clamping plate is provided on the outer side wall of the shell.

[0015] Through the utility model, a user can clamp the shell onto clothes, trousers, etc. through the clamping plate, so that it is convenient for the user to carry the measuring tape. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0022] Example 1

[0023] like Figure 1-5As shown in the figure, this embodiment provides a two-in-one tape measure, including a shell 100, a mounting cavity 210 is provided inside the shell 100, and an opening 120 communicating with the mounting cavity 210 is provided at the side wall of the lower end of the shell 100; a winding belt 220 is provided in the mounting cavity 210, and a measuring scale 130 with one end connected to the winding belt 220 and the other end extending into the opening 120; a deceleration mechanism 330 is provided in the mounting cavity 210 near the opening 120, and the deceleration mechanism 330 is used to slow down the speed at which the winding belt 220 retracts the measuring scale 130.

[0024] According to this embodiment, when the object to be measured is long, the user pulls the measuring ruler 130 out of the installation cavity 210 for measurement. After the measurement is completed, the measuring ruler 130 is released, and the winding belt 220 pulls the measuring ruler 130 back into the installation cavity 210. During this process, the deceleration mechanism 330 reduces the speed at which the measuring ruler 130 enters the installation cavity 210, thereby preventing the measuring ruler 130 from scratching the palm or arm of the user due to the winding belt 220 winding up too quickly.

[0025] In this embodiment, the mitigation mechanism 330 includes columns 410 arranged on both sides of the measuring scale 130, and a sleeve 510 is sleeved on the column 410. A clamp 520 extending toward the measuring scale 130 is provided on the side wall of the sleeve 510, and a spring 320 for pushing the clamp 520 toward the measuring scale 130 is provided between the clamp 520 and the inner wall of the installation cavity 210.

[0026] According to this embodiment, when the winding belt 220 retracts the measuring ruler 130 into the installation cavity 210, the spring 320 pushes the clamping plate 520, so that the sleeve 510 rotates along the column 410, and finally the clamping plate 520 squeezes the measuring ruler 130. The friction between the clamping plate 520 and the measuring ruler 130 slows down the speed at which the measuring ruler 130 enters the installation cavity 210, thereby preventing the user from being injured due to the measuring ruler 130 being retracted too quickly by the winding belt 220.

[0027] In this embodiment, a sponge plate 530 is provided on one end surface of the clamping plate 520 close to the measuring ruler 130 .

[0028] According to this embodiment, the sponge board 530 is deformed when in contact with the measuring ruler 130 when the clamping plate 520 is pushed by the spring 320, so as to prevent the measuring ruler 130 from being damaged when the clamping plate 520 squeezes the measuring ruler 130, thereby extending the service life of the measuring ruler 130.

[0029] In this embodiment, a support plate 540 for supporting the measuring ruler 130 is provided at the lower end of the clamping plate 520 .

[0030] Through this embodiment, when the measuring ruler 130 enters and exits the opening 120, the support plate 540 props up the measuring ruler 130, so that the measuring ruler 130 is more stable when moving. At the same time, the support plate 540 contacts the lower end surface of the measuring ruler 130, increasing the contact area between the measuring ruler 130 and the support plate 540, thereby increasing the friction between the measuring ruler 130 and the support plate 540, and slowing down the speed of the measuring ruler 130 when it is recovered; the support plate 540 is located below the measuring ruler 130, thereby avoiding contact with the scale lines on the measuring ruler 130, preventing the scale lines from being damaged due to wear.

[0031] In this embodiment, a blind hole 310 is provided on the inner wall of the installation cavity 210 for the spring 320 to extend into.

[0032] Through this embodiment, the installer inserts one end of the spring 320 into the blind hole 310 and the other end abuts against the clamping plate 520 , thereby preventing the spring 320 from being displaced when being squeezed by the clamping plate 520 .

[0033] In this embodiment, an L-shaped clamping plate 110 is disposed on the outer side wall of the housing 100 .

[0034] Through this embodiment, the user can clip the housing 100 onto clothes, pants, etc. through the clip plate 110, so that the user can carry the measuring tape conveniently.

[0035] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0036] The above is a schematic description of the present invention and its implementation methods, which is not restrictive. The embodiments shown are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the present invention, they should all fall within the protection scope of the present invention.
