Abstract
Description
Technical Field
[0001] This invention relates to the field of measuring tools, and more specifically, to measuring tapes. Background Technology
[0002] A utility model patent with patent application number "CN202420174906.4" and title "A Measuring Tape" discloses a measuring tape structure, including a measuring tape housing, a measuring tape reel, and a pressing component. The measuring tape reel is rotatably disposed within the housing. The pressing component includes a pressing part, a rotating part, and a braking part. The rotating part is rotatably connected within the housing, with one end connected to the pressing part and the other end connected to the braking part. The pressing part is configured to move relative to the housing, causing the rotating part to rotate relative to the housing and drive the braking part to move, so that the braking part selectively brakes the measuring tape reel.
[0003] The housing includes a first housing and a second housing, with the reel tape and the pressing member disposed between the first housing and the second housing. One of the first housing and the second housing, located close to each other, has a positioning post, and the other has a positioning hole, with the positioning post passing through the positioning hole. A clearance groove is formed between the rotating part and the braking part to allow the positioning post to pass.
[0004] In the above structure, the clearance groove is distributed on the outer periphery of the rotating part (measuring tape shaft). That is, the clearance groove is formed at the edge of the entire first housing and the second housing. There is no fixation between the center position of the first housing and the second housing (that is, the center position of the corresponding rotating part), which can easily cause assembly clearance between the rotating part and the first housing and the second housing at this position, resulting in abnormal noise when using the measuring tape.
[0005] For the reasons mentioned above, it is necessary to improve the existing technology. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides a novel measuring tape.
[0007] The present invention is achieved through the following technical solution: a novel measuring tape, comprising a housing, a measuring tape with a roller, a pressing element, and a measuring tape roller, wherein the roller is rotatably disposed within the housing, and the measuring tape is wound around the roller. The housing comprises a first housing and a second housing. The first housing includes a first support seat located on its inner side, and a first through hole is provided through the first support seat. A baffle seat communicating with the first through hole is provided on the outer side of the first housing.
[0008] The second housing includes a second support located on its inner side, and a second through hole extending through the second support;
[0009] It also includes a pull rod, which includes a baffle plate, a fixed seat, and a pull rod body protruding from one side of the fixed seat. The tail of the pull rod body is an enlarged connector. A partition groove is formed in the length direction of the pull rod body to divide the pull rod body into two unconnected rod-shaped parts. A threaded hole is formed in the connector.
[0010] The pull rod passes through the first through hole of the first housing and is inserted into the second through hole of the second housing. The baffle of the pull rod is limited in the baffle seat, and the connector of the pull rod is limited in the second through hole. A fastener is screwed into the threaded hole of the connector in the second through hole.
[0011] In the above technical solution, one of the first housing and the second housing is provided with a positioning post on the side that is close to each other, and the other is provided with a positioning hole, with the positioning post passing through the positioning hole.
[0012] In the above technical solution, the fixing seat is provided with a wing extending along the direction of the main body of the tie rod, and a wing groove along the axial direction of the through hole is provided on the first through hole.
[0013] In the above technical solution, the blade groove is provided with three grooves evenly spaced along the axial direction of the through hole.
[0014] In the above technical solution, a convex ring is formed in the middle of the fixed base, and the convex ring has a taper.
[0015] The present invention has the following beneficial effects: The measuring tape of the present invention tightens the center position of the first housing and the second housing by setting a pull rod, which can effectively avoid the assembly gap between the tape reel and the first housing and the second housing at this position, and prevent abnormal noise when using the measuring tape.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1 to 8 A novel measuring tape includes a housing 1, a tape reel 2, a pressing element 3, and a tape reel 4. The reel 4 is rotatably disposed inside the housing 1, and the tape 2 is wound around the reel 4. The housing 1 includes a first housing 11 and a second housing 12. The first housing 11 includes a first support seat 11a located on its inner side, and a first through hole 101 is provided through the first support seat 11a. A baffle seat 11b communicating with the first through hole 101 is provided on the outer side of the first housing 11.
[0025] The second housing 12 includes a second support 12a located on its inner side, and a second through hole 102 is provided through the second support 12a;
[0026] It also includes a pull rod 5, which includes a baffle 50, a fixing seat 51 and a pull rod body 52 protruding from one side of the fixing seat 51, the tail of the pull rod body 52 is an enlarged connector 53, a dividing groove 55 is formed in the length direction of the pull rod body 52 to divide the pull rod body into two non-connected rod-shaped parts 54, and a threaded hole is formed on the connector 53.
[0027] The pull rod 5 passes through the first through hole 101 of the first housing 11 and is inserted into the second through hole 102 of the second housing 12. The baffle 50 of the pull rod 5 is limited in the baffle seat 11b, and the connector 53 of the pull rod 5 is limited in the second through hole 102. A fastener is screwed into the threaded hole of the connector 53 in the second through hole 102.
[0028] In the above structure, the tape reel 4 is rotatably supported between the first support 11a and the second support 12a. By setting the tie rod 5 to tighten the center position of the first housing 11 and the second housing 12, the assembly clearance between the tape reel and the first and second housings at this position can be effectively avoided, preventing abnormal noise when using the tape measure. Furthermore, the damping between the tape reel 4 and the first support 11a and the second support 12a can be controlled by the depth of the fastener screwed into the threaded hole.
[0029] In the above technical solution, one of the first housing 11 and the second housing 12 is provided with a positioning post 200 and the other is provided with a positioning hole 201 on the side close to each other.
