Description

Technical Field

[0001] The present application relates to the field of calipers, and in particular to a caliper with a dust cover. Background Art

[0002] The diameter gauge can be used to measure the diameter information of various rolled products online, and can measure the maximum diameter, minimum diameter, average diameter, ovality and other information online.

[0003] At present, the Chinese utility model patent with publication number CN218723904U discloses a laser diameter gauge, including a frame, an avoidance groove, a laser component, a control screen and a guide wheel. The top surface of the frame forms an avoidance groove for placing the pipe, the laser component is arranged on the inner wall of the frame, the control screen is installed on the front wall of the frame, and the guide wheel is movably connected to the frame through an adjustment mechanism. The output shaft of the driving motor drives the screw to rotate, and the screw drives the threaded sleeve to drive the corresponding connecting rods to approach each other. The two connecting rods approach each other and push the corresponding guide wheels to adjust the distance between the two guide wheels to adapt to pipes of different diameters. This application has the effect of high guide wheel adjustment accuracy.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: when the caliper is not in use for a long time, the caliper is exposed to the air and dust easily adheres to the laser component, affecting the measurement accuracy of the laser. Utility Model Content

[0005] In order to reduce the impact of dust on measurement accuracy, the present application provides a caliper with a dust cover.

[0006] The present application provides a caliper with a dust cover, which adopts the following technical solution:

[0007] A caliper with a dust cover includes a caliper body, a protective cover and a locking piece. The upper end surface of the caliper body is provided with a measuring groove for material to pass through in a vertical downward direction. Receivers are respectively provided on the two opposite side walls of the measuring groove. The two receivers are respectively used to emit laser and receive laser. The protective cover is slidably connected to the caliper body along the distribution direction of the two receivers. The protective cover is used to cover the measuring groove. The locking piece is used for the protective cover to keep covering the measuring groove.

[0008] By adopting the above technical solution, when the caliper body needs to work, the staff can place the material in the measuring slot, one of the two receiving parts emits laser, and the other receives laser to measure the diameter of the material. When the caliper does not need to work, the staff can move the protective cover, and the protective cover covers the measuring slot. The protective cover and the caliper body make the measuring slot an internal cavity, reducing the contact between dust and the receiving parts, and reducing the impact of dust on measurement accuracy. The locking part keeps the protective cover sealed in the measuring slot, thereby improving the reliability of the protective cover.

[0009] Optionally, the locking member includes a locking block, which is arranged at the bottom of the measuring slot, and the protective cover is provided with a snap-in slot for snapping with the locking block, and the locking block is made of soft material.

[0010] By adopting the above technical solution, when the staff needs to seal the measuring groove to reduce the contact between dust and the receiving piece, the staff can move the protective cover, and the locking block contacts the protective cover and deforms until the locking block enters the card slot. The shape of the locking block is restored, and the locking piece keeps the position of the protective cover relative to the caliper body unchanged, thereby improving the reliability of the protective cover.

[0011] Optionally, the caliper body is also provided with a retaining member for keeping the protective cover away from the measuring slot, the retaining member includes a retaining bead and a retaining spring, the length direction of the retaining spring is perpendicular to the sliding direction of the protective cover, one end of the retaining spring is provided on the caliper body, the retaining bead is provided on the retaining spring, a retaining slot is provided on the inner side wall of the protective cover, and the retaining bead is used to engage with the retaining slot.

[0012] By adopting the above technical solution, before the staff needs to measure the material, they need to move the protective cover that originally covers the measuring slot until the material can be placed in the measuring slot. At this time, the retaining bead is snapped into the retaining slot under the action of the elastic force of the retaining spring, so that the staff can ensure that the protective cover will not move relative to the caliper body when placing the caliper body or during the measurement process, thereby improving the reliability of the protective cover.

[0013] Optionally, the retaining member also includes a retaining sleeve, a mating groove is provided on the caliper body, the mating groove extends along the length direction of the retaining spring, the retaining sleeve is coaxially arranged with the mating groove, the retaining sleeve is threadedly connected to the mating groove, and the retaining bead is slidably connected to the retaining sleeve along the vertical direction.

[0014] By adopting the above technical solution, the retaining sleeve allows the retaining bead to slide, and the protective sleeve is threadedly connected to the mating groove. Therefore, the retaining spring only exerts elastic force in the length direction of the retaining spring toward the retaining bead, reducing the influence of the protective cover on the retaining spring during movement, thereby improving the reliability of the retaining component.

[0015] Optionally, the protective cover is provided with a plurality of anti-slip strips for easy movement by staff.

[0016] By adopting the above technical solution, the anti-slip strip makes it easier for workers to move the protective cover and to separate the protective cover from the locking piece or the retaining piece.

[0017] Optionally, the caliper body is also provided with a cleaning assembly for cleaning dust from the surface of the hair receiving piece, and the cleaning assembly includes two cleaning rods and a sliding frame, and the sliding frame is slidably connected to the measuring slot along the axis direction of the material, and the two cleaning rods correspond one-to-one to the two hair receiving pieces, and the cleaning rods are arranged on the sliding frame, and the cleaning rods are used to abut against the surface of the hair receiving piece.

[0018] By adopting the above technical solution, the protective cover isolates the external dust. When the working environment is relatively harsh, dust will also exist between the protective cover and the measuring slot, and the dust will also stick to the hair receiving parts. Before subsequent construction is required, the staff can move the sliding frame, and the sliding frame drives the two cleaning rods to move. The cleaning rods clean the surfaces of the two hair receiving parts to reduce the dust sticking to the surfaces of the hair receiving parts.

[0019] Optionally, the cleaning component also includes a driving member, which includes two synchronous wheels, a synchronous belt and a synchronous rack. The two synchronous wheels are distributed along the sliding direction of the sliding frame. The synchronous belt is sleeved on the two synchronous wheels. The sliding frame is arranged on the synchronous belt. The length direction of the synchronous rack is parallel to the sliding direction of the protective cover. The synchronous rack is arranged on the protective cover. The synchronous belt is provided with a number of teeth for engaging with the synchronous rack.

[0020] By adopting the above technical solution, when the staff opens or closes the protective cover, the movement of the protective cover will drive the movement of the synchronous rack, which will engage with the teeth on the synchronous belt. The synchronous belt will rotate around the two synchronous wheels, and the synchronous belt will drive the sliding frame to move. The movement of the sliding frame will drive the two cleaning rods to remove dust from the surfaces of the two hair receiving parts. No additional operation is required by the staff, and dust adhesion to the surface of the hair receiving parts can be reduced before work.

[0021] Optionally, the cleaning rod includes a mounting rod and a cleaning cloth, the mounting rod is arranged on the sliding frame, and the cleaning cloth is slidably connected to the mounting rod along a sliding direction perpendicular to the sliding frame.

[0022] By adopting the above technical solution, when cleaning the surface of the docking parts for a long time, a large amount of dust will be present on the surface of the cleaning cloth, and the staff needs to replace it in time. The staff can slide the old cleaning cloth out of the mounting rod and then slide the new cleaning cloth onto the mounting rod to complete the replacement operation. The replaceable cleaning cloth improves the reliability of the cleaning component.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The protective cover is used to reduce the contact between the hair extension on the diameter gauge body and dust;

[0025] 2. The retaining member and the locking member are used to control the opening and closing state of the protective cover, thereby improving the reliability of the protective cover;

The synchronous rack 533 is used to engage with the latch teeth 534.

[0039] Reference Figure 1 and Figure 4 A support assembly 7 for supporting rod-shaped materials is also provided on the caliper body 1. The support assembly 7 includes two support frames 71 and two support rollers 72. The two support frames 71 are distributed along the width direction of the caliper body 1. The two support frames 71 are located on both sides of the caliper body 1. The two support rollers 72 correspond to the two support frames 71 one by one. The support rollers 72 are horizontally arranged and rotatably connected to the support frames 71. The support rollers 72 are V-shaped rollers.

[0040] The implementation principle of a caliper with a dust cover in an embodiment of the present application is as follows: when the staff needs to use the caliper to measure rod-shaped materials, the staff slides the protective cover 2 through the anti-slip strip 22, and the locking block 31 originally clamped to the clamping groove 21 is deformed, and the locking block 31 disengages from the clamping groove 21 until the retaining groove 23 on the protective cover 2 is clamped with the retaining bead 41. At this time, the measuring groove 11 is exposed. During the movement of the protective cover 2, the protective cover 2 drives the synchronous rack 533 to move, and the synchronous rack 533 engages with the clamping teeth 534 on the synchronous belt 532. The rotation of the synchronous belt 532 drives the sliding frame 52 to move, and the sliding frame 52 drives the two cleaning rods 51 to move relative to the receiving piece 6, and the cleaning cloth 512 removes dust on the caliper.

[0041] The staff places the material on two support rollers 72. Through the two support rollers 72, the length direction of the rod-shaped material is parallel to the width direction of the caliper body 1. At this time, the staff can measure the diameter of the rod-shaped material through the receiving piece 6. When the measurement is completed, the staff moves the protective cover 2, and the retaining groove 23 of the protective cover 2 is disengaged from the retaining bead 41 until the snap-fitting groove 21 of the protective cover 2 is snap-fitted with the locking block 31. At this time, the measuring groove 11 is covered by the protective cover 2, reducing the contact of external dust with the surface of the receiving piece 6.

[0042] When the cleaning cloth 512 wipes away a lot of dust, the staff needs to replace the cleaning cloth 512 in time to reduce the dust from the cleaning cloth 512 to the surface of the hair receiving piece 6 when the cleaning cloth 512 is wiping the surface of the hair receiving piece 6.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
