Abstract
Description
Technical Field
[0001] This invention relates to the field of disassembly and assembly tools, and specifically to a terminal block. Background Technology
[0002] In current industrial production scenarios, after using a terminal cutter to tighten or loosen screws, it is often necessary to label the terminal where the screw was located on the cabinet door of the terminal box containing the terminal block to clearly identify the corresponding signal content. During the work process, after using the terminal cutter, operators usually take out a marker to write the label on the cabinet door. However, operators often forget to bring a marker, making it impossible to label in time. When they come back to label again, they forget what type of terminal it is, resulting in low work efficiency. Summary of the Invention
[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a terminal block with high operating efficiency.
[0004] The terminals in this embodiment of the invention include:
[0005] Screwdriver tip;
[0006] A connecting rod, one end of which has a first insertion hole for inserting the screwdriver bit;
[0007] A rotating handle, which is rotatably located at the other end of the connecting rod;
[0008] A pen holder, which is rotatably connected to the rotating handle;
[0009] A cylindrical cam is disposed inside the pen holder. The outer circumferential surface of the cylindrical cam has a cam groove, and the inner circumferential surface of the pen holder has a cam pusher. A portion of the cam pusher is placed within the cam groove and slidably engages with it. A rotating handle has a first mating part located inside the pen holder, and the cylindrical cam has a second mating part that engages with the first mating part. Rotation of the rotating handle causes the cylindrical cam to reciprocate axially within the pen holder. The end of the cylindrical cam furthest from the rotating handle has a second insertion hole.
[0010] The pen refill has a pen barrel and a pen tip. The pen barrel is inserted into the second socket. The cylindrical cam can move to drive the pen tip to extend out of or into the pen barrel.
[0011] In some embodiments, one of the rotary handle and the cylindrical cam has a first sliding portion extending axially along the pen cylinder, and the other of the rotary handle and the cylindrical cam has a first sliding groove extending axially along the pen cylinder, wherein the first sliding portion slidably engages with the first sliding groove along the axial direction of the pen cylinder.
[0012] One of the first sliding part and the first sliding groove forms the first mating part, and the other of the first sliding part and the first sliding groove forms the second mating part.
[0013] In some embodiments, the rotating handle has a plurality of first sliding portions, which are spaced apart circumferentially along the pen holder. The cylindrical cam has a plurality of first sliding grooves, and the plurality of first sliding portions correspond one-to-one with and cooperate with the plurality of first sliding grooves.
[0014] In some embodiments, the connecting rod has a first limiting groove extending axially along the connecting rod, and the rotating handle has a second limiting groove extending axially upward along the connecting rod.
[0015] The terminal block also includes a limiting member, which is disposed in the first limiting groove and is movable along the extension direction of the first limiting groove. When the limiting member moves to the point where a part of the limiting member is placed in the first limiting groove and the other part of the limiting member is placed in the second limiting groove, the rotating handle cannot rotate relative to the connecting rod.
[0016] In some embodiments, the limiting member is a rod body, which includes a first rod body, a second rod body, and a third rod body connected in sequence. The first rod body and the third rod body extend radially along the connecting rod, and the second rod body extends axially along the connecting rod.
[0017] In some embodiments of the present invention, the terminal further includes a compression spring, which is disposed in the first limiting groove. The compression spring is located between the second rod and the bottom wall of the first limiting groove, and the compression spring provides the limiting member with an elastic force toward the rotating handle.
[0018] In some embodiments, the second socket is a tapered hole, and the cross-sectional area of the second socket gradually increases from the cylindrical cam to the pen refill.
[0019] In some embodiments, the other end of the connecting rod has a rotating shaft, and the rotating handle has a mating hole, the rotating shaft extending into the mating hole and rotatingly engaging with the mating hole.
[0020] In some embodiments, the number of cam push rods is two, and the two cam push rods are spaced apart axially on the pen holder.
[0021] In some embodiments, the rotary handle has friction threads.
[0022] In this embodiment of the terminal screwdriver, during use, the screwdriver bit is used to tighten or loosen the screws on the terminals. After the screws are tightened, one hand keeps the pen holder stationary while the other hand rotates the handle. Under the action of the first and second mating parts, rotating the handle drives the cylindrical cam to rotate. Simultaneously, the cylindrical cam, under the action of the cam groove and cam push rod, can move axially in the pen holder, causing the pen tip to extend out of the pen holder for marking the terminal box. After marking, rotating the handle retracts the pen tip into the pen holder, preventing the pen tip from interfering with the normal use of the screwdriver bit when tightening or loosening the screws. Compared with related technologies, this embodiment of the terminal screwdriver allows for timely marking of the terminal box information using the pen tip after tightening or loosening the screws, avoiding situations where the terminal box is forgotten or missed due to forgetting to bring a marker. Retracting the pen tip into the pen holder promptly after marking the terminal box prevents the pen tip from interfering with the normal use of the screwdriver bit, greatly improving work efficiency.
[0023] Therefore, the terminals of the present invention have the advantages of high working efficiency. Attached Figure Description

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0039] The technical solution of this application will now be described in detail with reference to the accompanying drawings.
[0040] like Figures 1 to 4 As shown, the terminal screwdriver 100 of this embodiment includes a screwdriver head 1, a connecting rod 2, a rotating handle 3, a pen holder 4, a cylindrical cam 5, and a pen refill 6. One end of the connecting rod 2 has a first insertion hole 201 for inserting the screwdriver head 1, the rotating handle 3 is rotatably disposed at the other end of the connecting rod 2, and the pen holder 4 is rotatably connected to the rotating handle 3.
[0041] A cylindrical cam 5 is disposed inside the pen holder 4. The outer circumferential surface of the cylindrical cam 5 has a cam groove 501, and the inner circumferential surface of the pen holder 4 has a cam push rod 401. A portion of the cam push rod 401 is placed in the cam groove 501 and slidably engages with the cam groove 501. The rotating handle 3 has a first engaging part 301 located inside the pen holder 4, and the cylindrical cam 5 has a second engaging part 502 that engages with the first engaging part 301. Rotating the rotating handle 3 can drive the cylindrical cam 5 to reciprocate along the axial direction of the pen holder 4. The end of the cylindrical cam 5 away from the rotating handle 3 has a second insertion hole 503.
[0042] The pen refill 6 has a pen barrel 601 and a pen tip 602. The pen barrel 601 is inserted into the second insertion hole 503. The movement of the cylindrical cam 5 can drive the pen tip 602 to extend out of the pen holder 4 or into the pen holder 4.
[0043] In use, the terminal screwdriver 100 of this embodiment uses the screwdriver bit 1 to tighten or loosen the screws on the terminals. After the screws are tightened, one hand keeps the pen holder 4 stationary while the other hand rotates the handle 3. Under the action of the first mating part 301 and the second mating part 502, rotating the handle 3 drives the cylindrical cam 5 to rotate. Simultaneously, the cylindrical cam 5 can move axially in the pen holder 4 under the action of the cam groove 501 and the cam push rod 401, causing the pen tip 602 of the pen refill 6 to extend out of the pen holder 4 for marking the terminal box. After marking is completed, rotating the handle 3 allows the pen tip 602 of the pen refill 6 to extend into the pen holder 4, preventing the pen tip 602 from interfering with the normal use of the screwdriver bit 1 when tightening or loosening the screws. Compared with related technologies, the terminal screwdriver 100 of this embodiment can promptly mark the information of the terminal box using the pen refill 6 after tightening or loosening the screws on the terminals, avoiding situations where the terminal box is forgotten or omitted due to forgetting to bring a marker pen. After marking the terminal box, promptly insert the pen refill 6 into the pen holder 4 to prevent the pen refill 6 from affecting the normal use of the screwdriver bit 1, thus greatly improving work efficiency.
[0044] Therefore, the terminal starter 100 of the present invention has the advantages of high working efficiency.
[0045] In some embodiments, one of the rotating handle 3 and the cylindrical cam 5 has a first sliding portion extending axially along the pen holder 4, and the other of the rotating handle 3 and the cylindrical cam 5 has a first sliding groove extending axially along the pen holder 4. The first sliding portion slidably engages with the first sliding groove along the axial direction of the pen holder 4.
[0046] One of the first sliding part and the first sliding groove forms a first mating part 301, and the other of the first sliding part and the first sliding groove forms a second mating part 502.
[0047] For example, such as Figure 2 and Figure 3 As shown, the rotating handle 3 is provided with a first sliding part, and the cylindrical cam 5 is provided with a first sliding groove. The first sliding part can slide along the axial direction of the pen holder 4 and cooperate with the first sliding groove.
[0048] Specifically, when the rotary handle 3 is rotated, the cylindrical cam 5 rotates under the action of the first sliding part and the first sliding groove. Because the cylindrical cam 5 rotates and moves axially in the pen holder 4 under the action of the cam push rod 401 and the cam groove 501, the pen tip 602 of the pen refill 6 extends out or into the pen holder 4, thus making the structure of the first mating part 301 and the second mating part 502 simple and easy to assemble.
[0049] In some embodiments, the rotating handle 3 has a plurality of first sliding parts, which are spaced apart circumferentially along the pen holder 4. The cylindrical cam 5 has a plurality of first sliding grooves, and the plurality of first sliding parts correspond to and cooperate with the plurality of first sliding grooves one by one.
[0050] For example, such as Figure 2 and Figure 3 As shown, multiple first sliding parts are evenly spaced along the circumference of the rotating handle 3, and multiple first sliding grooves are evenly spaced along the circumference of the cylindrical cam 5. By setting multiple first sliding parts and multiple sliding grooves to correspond one-to-one and cooperate, it is beneficial to improve the uniformity of force on the rotating handle 3 and the cylindrical cam 5, thereby improving the working reliability of the terminal starter 100 in this embodiment of the invention.
[0051] In some embodiments, the connecting rod 2 has a first limiting groove 202 extending axially along the connecting rod 2, and the rotating handle 3 has a second limiting groove 302 extending axially upward along the connecting rod 2.
[0052] The terminal block also includes a limiting member 7, which is disposed in the first limiting groove 202 and is movable along the extending direction of the first limiting groove 202. When the limiting member 7 moves to the point where part of the limiting member 7 is placed in the first limiting groove 202 and the other part of the limiting member 7 is placed in the second limiting groove 302, the rotating handle 3 cannot rotate relative to the connecting rod 2.
[0053] For example, such as Figures 2 to 4 As shown, when tightening or loosening the screw on the terminal, a portion of the limiting member 7 can be controlled to slide into the second limiting groove 302, so that the rotating handle 3 cannot rotate relative to the connecting rod 2, so that the screw can be rotated by the combined action of the rotating handle 3 and the connecting rod 2, which helps to improve the tightening and loosening efficiency of the screw.
[0054] In some embodiments, such as Figure 4 As shown, the limiting member 7 is a rod body, which includes a first rod body 701, a second rod body 702 and a third rod body 703 connected in sequence. The first rod body 701 and the third rod body 703 extend radially along the connecting rod 2, and the second rod body 702 extends axially along the connecting rod 2. By setting the limiting member 7 as a rod body, the limiting member 7 has a simple structure and is easy to process and manufacture.
[0055] In some embodiments of the present invention, the terminal 100 further includes a compression spring 8, which is disposed in the first limiting groove 202. The compression spring 8 is located between the second rod body 702 and the bottom wall of the first limiting groove 202, and the compression spring 8 gives the limiting member 7 an elastic force toward the rotating handle 3.
[0056] In other words, when the terminal setter 100 is not in use, the limiting member 7 is always partially placed in the second limiting groove 302 under the action of the compression spring 8, so that the connecting rod 2 and the rotating handle 3 cannot rotate relative to each other. The screw can be tightened or loosened by the rotating handle 3 and the connecting rod 2 together. When adjusting the pen tip 602 of the pen refill 6 extending out and into the pen holder 4, the limiting member 7 can also be slid into the first limiting groove 202, so that the rotating handle 3 rotates relative to the connecting rod 2 for adjustment, thereby making the terminal setter 100 of this embodiment of the invention easy to adjust.
[0057] Optionally, the second socket 503 is a tapered hole, and the cross-sectional area of the second socket 503 gradually increases from the cylindrical cam 5 to the pen refill 6. For example, as Figure 3 As shown, when the pen barrel 601 is inserted into the second socket 503, it can be quickly inserted into the second socket 503. As the insertion depth into the second socket 503 increases, the inner diameter of the second socket 503 decreases. The change in the inner diameter of the second socket 503 can be used to fix the pen barrel, thus making it easy to fix the pen barrel.
[0058] Optionally, such as Figure 2 and Figure 3 As shown, the other end of the connecting rod 2 has a rotating shaft 203, and the rotating handle 3 has a mating hole 303. The rotating shaft 203 extends into the mating hole 303 and rotates with the mating hole 303, which helps to improve the connection reliability between the connecting rod 2 and the rotating handle 3.
[0059] In some embodiments, there are two cam push rods 401, which are spaced apart axially from each other in the pen holder 4. For example, as Figure 3 As shown, one cam push rod 401 is located at the top of the cam groove 501, and the other cam push rod 401 is located at the bottom of the cam groove 501, so that the cylindrical cam 5 is subjected to uniform force during movement, avoiding jamming of the cam push rod 401 during movement, which helps to improve its working reliability.
[0060] In some embodiments, the rotating handle 3 has a friction thread 304. By setting the friction thread 304, it is beneficial to increase the friction with the hand, facilitate rotational force, and improve work efficiency.
