Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a cup mouth thread connection structure. Background Art

[0002] A glass cup is a cup made of glass, usually made of high borosilicate glass, fired at a high temperature of more than 600 degrees. It is a new type of environmentally friendly tea cup that is increasingly popular among people. The cup lid is usually made of plastic material, and the glass cup body and the cup lid are usually threaded.

[0003] The glass cups currently on the market have a wide variety of different shapes, parameters, pitches, and overlaps at the beginning and end of the thread at the cup mouth. They are not uniform, and the performance is poor and the screwing is not smooth.

[0004] Therefore, in view of the above-mentioned problems of the current glass cup and the cup cover, it is necessary to design a reasonable cup mouth connection structure to solve the existing technical problems. Utility Model Content

[0006] The technical solution of the utility model is as follows:

[0007] A cup mouth threaded connection structure includes a cup body, characterized in that the outer wall of the cup body mouth has a thread, and the thread is a single-start thread or a two-stage double-start thread. When the thread is a single-start thread, the thread wraps around the outer circumference of the cup mouth 1 to 2 times; when the thread is a two-stage double-start thread, the two stages of the double-start thread are relatively staggered, and the length of each stage of the double-start thread is greater than half a circle of the circumference of the cup body mouth.

[0008] Furthermore, when the thread is a single-start thread, the thread head segment and the thread tail segment overlap when projected downward, and the overlapping portion exceeds 1 / 3 of the circumference of the cup body mouth.

[0009] Furthermore, the head section of any one of the two double-start threads is located above the tail section of the other double-start thread, and the head section and the tail section overlap when projected downward.

[0012] Furthermore, the distance between the center of the head section of any one of the two double-start threads and the center of the tail section of the other double-start thread is 3.5-4.5 mm.

[0013] Furthermore, the distance between the center of the head section of any one of the two double-start threads and the center of the tail section of the other double-start thread is 3.8-4.2 mm.

[0014] Furthermore, the height of the cup body mouth is 18.2-18.8 mm, and the distance between the center of the tail section of the two double-start threads and the lower edge of the cup body mouth is 6.5-7.2 mm.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] A cup mouth thread connection structure comprises a cup body 1, wherein the outer wall of the mouth of the cup body 1 has a single-start thread 3 or two-stage double-start thread 2. When the thread is a single-start thread, the thread wraps around the outer circumference of the cup mouth 1 to 2 times; when the thread is a two-stage double-start thread, the two-stage double-start thread 2 is relatively staggered, and the head and tail of the two-stage double-start thread are staggered, and the length of each stage of the double-start thread is greater than half a circle of the circumference of the cup body mouth.

[0032] Furthermore, when the thread is a single-start thread 3, the thread head segment and the tail segment overlap when projected downward, and the overlapping portion exceeds 1 / 3 of the circumference of the cup body mouth.

[0033] Furthermore, the head section of any of the two double-start threads is located above the tail section of the other double-start thread, and the head section and the tail section overlap when projected downward. Generally, the overlapping section length L0 does not exceed 15 mm based on actual application effects.

[0034] Furthermore, a downwardly projected overlapping length L0 of a double-start thread head section and another double-start thread tail section is 8 to 15 mm.

[0035] Furthermore, the downwardly projected overlapping length L0 of a double-start thread head segment and another double-start thread tail segment is 10-12 mm. According to the current feedback from a large number of enterprise users and actual application effects, the actual application effect operation within this length range is the most convenient and reasonable.

[0036] Furthermore, the distance X between the center of the head section of any one of the two double-start threads and the center of the tail section of the other double-start thread is 3.5-4.5 mm.

[0037] Furthermore, the distance between the center of the head section of any one of the two double-start threads and the center of the tail section of the other double-start thread is 3.8-4.2 mm. The actual application effect and operation within this length range are the most convenient and reasonable.

[0038] Furthermore, the height H0 of the cup mouth is 18.2-18.8 mm, the distance H1 between the tail center of the two sections of double-start threads and the lower edge of the cup mouth is 6.5-7.2 mm, and the actual processing size is 6.6-7.1 mm.

[0039] Furthermore, the tooth profile standard of the single-start thread and double-start thread is: triangular thread tooth, tooth tip angle 60 degrees, tooth width L=2.4~2.8mm, tooth depth h=1.2~1.8mm, tooth top chamfer R=0.6~0.8mm, and the measurement position is 90 degrees from the tooth start. The tooth tip angle is 60 degrees, which is 60 degrees. The triangular thread is the basic form of the connecting thread, with high root strength and good self-locking performance.

[0040] Furthermore, the tooth width L of the single-start thread and the double-start thread is 2.5-2.6 mm, the tooth depth h is 1.35-1.5 mm, and the tooth top chamfer R is 0.7-0.75 mm.

[0041] From the perspective of the design that the cup mouth thread connection structure complies with the specifications, the position parameters of the single-start thread and the double-start thread at the cup mouth are the same, and the operation is smooth. It is a comprehensive design:

[0042] 1. When the threads on the outer wall of the cup mouth are double-threaded, the two sections of double-threaded threads are designed relatively on the outer wall of the cup mouth, and the overlap range of the head section of one double-threaded thread and the tail section of the other double-threaded thread, the overall height requirements of the cup mouth, the distance between the tail of the two sections of double-threaded threads and the lower edge of the cup mouth and other parameters are comprehensively considered to ensure that the cup body and the cup cover can rotate relative to each other ≥200° during the connection process, and can be opened or closed;

[0043] 2. When the thread on the outer wall of the cup mouth is a single-start thread, comprehensively consider the overlap range of the head section and the tail section of the single-start thread, the overall height requirement of the cup mouth, the distance between the tail of the two sections of double-start threads and the lower edge of the cup mouth, and other parameters to ensure that the cup body and the cup cover can rotate relative to each other ≥200° during the connection process and can be opened or closed;

[0044] 3. One section of single-start thread or two sections of double-start thread adopt triangular thread teeth. Parameters such as tooth tip angle, tooth width, and tooth top chamfer ensure high thread root strength, good self-locking performance, and smooth opening or closing.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
