Description

Technical Field

[0001] This utility model relates to the field of micrometer technology, specifically a micrometer with a support mechanism. Background Technology

[0002] A micrometer is a precision length measuring instrument that uses the principle of a precision threaded pair (micrometer screw) to convert a small linear displacement into an angular displacement and then reads it through an amplification mechanism (micrometer drum). A typical micrometer usually contains the following main components.

[0003] Ruler frame: A sturdy C- or U-shaped frame that provides support and reference;

[0004] Anvil: A very flat and hard measuring surface fixed to one end of the ruler frame;

[0005] Micrometer screw / mandrel: A screw that can move precisely, and its end face is also the measuring surface;

[0006] Fixed sleeve: Fixed to the ruler frame, with main scale graduations (millimeters and half-millimeters) engraved on it;

[0007] Differential sleeve: A sleeve connected to the micrometer screw, with 50 or 100 graduations evenly engraved on its circumference. Rotating the differential sleeve can drive the micrometer screw forward or backward.

[0008] Locking device / brake ring: Used to lock the position of the micrometer screw during reading to prevent movement;

[0009] The ratchet / force measuring device is located at the end of the differential drum. When the measuring surface contacts the workpiece and reaches the preset constant measuring force, the ratchet will slip and make a "clicking" sound to prevent measurement errors or damage to the instrument / workpiece due to excessive force.

[0010] The operation method is as follows:

[0011] Hold the measuring scale holder steady and rotate the ratchet to bring the measuring surface into contact with the workpiece. Stop after hearing a series of "clicks" (usually 2-3). Do not rotate the micrometer drum directly with excessive force. Before taking the reading, use the locking device to secure the screw. When taking the reading, keep your line of sight perpendicular to the scale line to avoid parallax.

[0012] In actual operation, one hand turns the ratchet while the other hand needs to keep the micrometer frame and the object to be measured stable, which is quite inconvenient. Therefore, there are support frames on the market for supporting and placing micrometers. However, these support frames are independent devices and are not convenient to carry or store at the same time as the micrometer, which is also inconvenient. Based on this, a micrometer with a support mechanism is provided. Utility Model Content

[0013] The purpose of this invention is to provide a micrometer with a support mechanism in order to solve the problems mentioned above.

[0014] To achieve the above objectives, the present invention provides the following technical solution: a micrometer with a support mechanism, comprising a micrometer, wherein the micrometer includes a frame, a protrusion, and a rotating groove;

[0015] The protruding block is fixed to the bottom of the ruler frame, the rotating groove is opened at the bottom of the protruding block, and an auxiliary support component is provided on the outside of the ruler frame and the protruding block. The auxiliary support component in the unfolded state is used to realize the stable placement of the micrometer on the workbench surface.

[0016] The auxiliary support assembly includes a concave support plate and a rotating connector;

[0017] The concave support plate is symmetrically attached to both sides of the ruler frame and the protruding block. The rotating connector is fixed to the bottom of one side of the concave support plate. The rotating connector is rotatably connected to the inside of the rotating groove through a rotating rod.

[0018] Two concave support plates rotate and unfold around the center of the rotating connector to provide support for the placement of the micrometer.

[0019] As a further improvement of this utility model: the protruding block is provided with a straight groove above the rotating groove, and the straight groove completely penetrates both sides of the protruding block;

[0020] A locking bolt is provided on the inner side of the straight groove. The screw of the locking bolt passes through the protrusion to the inside of the rotating groove and fits against the surface of the concave support plate. The screw of the rotating connector is threadedly connected to the protrusion to realize the rotation locking of the rotating connector.

[0021] As a further improvement of this utility model: two locking bolts are provided, which are diagonally distributed and aligned with the center lines of the two rotating connecting parts respectively.

[0022] As a further improvement of this utility model: the height of the straight groove is greater than the overall height of the locking bolt, and the knob side of the locking bolt does not protrude beyond the outside of the protrusion block.

[0023] As a further embodiment of this utility model: the ruler frame, protrusion, rotating groove, and straight groove are integrally formed by casting, and the concave support plate and rotating connector are formed by processing heat insulation material.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] By setting up an auxiliary support component, the micrometer can be placed stably on the workbench for use. At the same time, when the auxiliary support component is stored, it does not affect the handheld operation of the micrometer, making it easy to carry and store. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-3 In this embodiment of the utility model, a micrometer with a support mechanism includes a micrometer 1, which includes a frame 101, a protrusion 102, and a rotating groove 103.

[0032] The protrusion 102 is fixed to the bottom of the ruler frame 101, and the rotating groove 103 is opened at the bottom of the protrusion 102. An auxiliary support component 2 is provided on the outside of the ruler frame 101 and the protrusion 102. The auxiliary support component 2 in the unfolded state is used to realize the stable placement of the micrometer 1 on the surface of the workbench 3.

[0033] The auxiliary support assembly 2 includes a concave support plate 201 and a rotating connector 202;

[0034] The concave support plate 201 is symmetrically attached to both sides of the ruler frame 101 and the protruding block 102. The rotating connector 202 is fixed to the bottom of one side of the concave support plate 201. The rotating connector 202 is rotatably connected to the inside of the rotating groove 103 through the rotating rod.

[0035] Two concave support plates 201 rotate and unfold around the center of the rotating connector 202 to provide support for the placement of the micrometer 1.

[0036] In this embodiment, it should be noted that the micrometer 1 is a common model of micrometer on the market. Therefore, other parts on the frame 101 (such as anvil, micrometer screw / mandrel, fixed sleeve, micrometer drum, locking device / brake ring, ratchet / force measuring device) will not be described in detail here.

[0037] The usage method of this micrometer 1 is as follows:

[0038] One method is handheld operation, in which the concave support plate 201 is attached to the side of the frame 101, which is the same as the traditional micrometer 1 usage method (it should be noted that the inner groove trajectory of the concave support plate 201 matches the inner groove trajectory of the frame 101, which does not affect the normal use of the micrometer 1).

[0039] Another method is to place the micrometer 1 on the workbench 3 for use. In this case, the two concave support plates 201 are manually flipped. By flipping and opening the two concave support plates 201, support can be provided for the placement of the micrometer 1. Furthermore, by changing the included angle between the two concave support plates 201, different angles can be achieved for the placement of the micrometer 1 (e.g., ...). Figure 2 By placing the micrometer 1 on the workbench 3, one hand can be freed up to pick up the object to be measured, making the operation more convenient.

[0040] Please refer to this carefully. Figures 1-3 The protruding block 102 is located above the rotating groove 103 and has a straight groove 104 that completely penetrates both sides of the protruding block 102.

[0041] A locking bolt 203 is provided on the inner side of the straight slot 104. The screw of the locking bolt 203 passes through the protrusion 102 to the inside of the rotating slot 103 and is in contact with the surface of the concave support plate 201. The screw of the rotating connector 202 is threadedly connected to the protrusion 102 to realize the rotation locking of the rotating connector 202.

[0042] There are two locking bolts 203, which are diagonally distributed and aligned with the center lines of the two rotating connectors 202 respectively;

[0043] The height of the straight groove 104 is greater than the overall height of the locking bolt 203, and the knob side of the locking bolt 203 does not protrude from the outside of the protrusion 102.

[0044] In this embodiment: after the concave support plate 201 is unfolded and the angle is determined, the knob of the locking bolt 203 can be manually turned to rotate it, thereby causing the screw of the locking bolt 203 to be screwed downward and pressed against the surface of the rotating connector 202, thereby reinforcing the angle of the concave support plate 201 and making the micrometer 1 more stable (it should be added that: there is rotational resistance between the rotating connector 202 and the convex block 102, which can maintain relative fixation under the condition of no large external force, thereby keeping the concave support plate 201 in a stable storage state).

[0045] When the concave support plate 201 is in the retracted state, the bottom of the screw part of the locking bolt 203 does not contact the rotating connector 202, and the concave support plate 201 completely covers the straight groove 104.

[0046] Please refer to this carefully. Figures 1-3 The ruler frame 101, protruding block 102, rotating groove 103, and straight groove 104 are integrally formed by casting process, while the concave support plate 201 and rotating connector 202 are formed by heat insulation material.

[0047] In this embodiment: the material of the protrusion 102 is the same as that of the ruler frame 101, which does not affect the use of the micrometer;

[0048] The concave support plate 201 and the rotating connector 202 can be integrally molded from engineering plastics, which has a good heat insulation effect and can avoid thermal expansion errors caused by prolonged contact of hand temperature with the ruler frame 101 during hand operation.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
