Description

Technical Field

[0001] The invention relates to the technical field of lead seals, in particular to a threading type metering seal and a method thereof. Background Art

[0002] Lead seal threading is a physical sealing technology used to ensure the safety and prevent tampering of metering equipment such as electricity meters and water meters. It passes the lead seal wire through the specific hole of the metering equipment and then fixes the lead seal to ensure the sealing and safety of the equipment.

[0003] At present, the double-hole lead wire design of the metering lead seal has achieved a single permanent anti-theft state of the lead seal, but the small diameter of the lead wire hole has a great impact on the elderly or poor eyesight of the operators. At the same time, after the lead seal is sealed, the excess lead wire needs to be cut off one by one with tools. A new user needs more than 20 lead seals. Cutting the wire is very time-consuming and the work efficiency is extremely low. Secondly, the softness of the sandwich iron sheet cannot be closed and the unopened state caused by production problems causes a large amount of lead seals to be wasted, resulting in a large amount of funds and materials.

[0004] Based on the above problems, we proposed a threading metering seal and method. Summary of the invention

[0005] In view of the technical problem that after the above-mentioned existing lead seal is sealed, the excess lead wires need to be trimmed one by one, resulting in low work efficiency, the threading metering seal in the present invention is proposed.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a threaded metering seal, which includes a main body component, including a shell, a through hole penetrating the outer wall of the shell, a half hole penetrating the outer wall of the shell, a notch provided on the outer wall of the shell, a receiving groove provided on the outer wall of the shell, a matching groove provided below the receiving groove and an accommodating space provided below the receiving groove; a fastening component, including a pressure block, a blade provided below the pressure block, an insert plate provided below the pressure block and a first inclined plate and a second inclined plate provided on the outer wall of the insert plate.

[0007] As a preferred solution of the threaded metering seal of the present invention, grooves are provided on the outer walls on both sides of the shell, and the half hole is connected with the notch.

[0008] As a preferred solution of the threaded metering seal of the present invention, a first slideway and a second slideway are provided in the accommodating space, and the first slideway and the second slideway are centrally symmetrically arranged.

[0009] As a preferred solution of the threaded metering seal of the present invention, the inner wall of the accommodating space is provided with two inclined surfaces, and the tops of the first slideway and the second slideway are both provided with concave surfaces.

[0010] As a preferred solution of the threaded metering seal of the present invention, a blade is provided below the blade, and the blade is movably matched with the bottom of the matching groove.

[0011] As a preferred solution of the threaded metering seal of the present invention, the first inclined plate and the second inclined plate are respectively slidably matched with corresponding inclined surfaces.

[0012] As a preferred solution of the threaded metering seal of the present invention, the first inclined plate and the second inclined plate are centrally symmetrically arranged.

[0013] As a preferred solution of the threaded metering seal of the present invention, the first inclined plate is slidably matched with the first slideway, and the second inclined plate is slidably matched with the second slideway.

[0014] One beneficial effect of the present invention is that by setting a notch, the complicated punching operation is transformed into a relatively simple operation of wrapping around the notch, and the lead wire is clamped in the accommodating space through the previous pressing method to form a "W" clamping position, which is more stable and prevents slipping. At the same time, a matching groove is added inside the lead seal to achieve cutting off of excess lead wire while pressing the seal.

[0015] In view of the above technical problem that the existing operators who are old or have poor eyesight have difficulty in operation, the threading metering sealing method of the present invention is proposed.

[0016] In order to solve the above technical problem, the present invention provides the following technical solution: the lead wire passes through the through hole and the half hole successively, and the pressing block is pressed to lock the lead wire.

[0017] As a preferred solution of the threading metering sealing method of the present invention, the pressure is continuously applied, and the blade flexibly cooperates with the bottom of the matching groove to cut off the excess lead wire.

[0018] Another beneficial effect of the present invention is that the seal structure is exquisitely designed, simple, reasonable and compact, adopts a one-hole and one-notch design, and at the same time adds a thread cutting function to the seal, thereby expanding the applicable population, reducing the impact of visual defects and old age on the lead sealing work, and making it more convenient to use.

[0030] Example 1, reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a threaded metering seal, including a main body component 100, by providing a shell 101, a through hole 102 penetrating the outer wall of the shell 101, a half hole 103 penetrating the outer wall of the shell 101, a notch 103a provided on the outer wall of the shell 101, a receiving groove 104 provided on the outer wall of the shell 101, a matching groove 104a provided below the receiving groove 104 and an accommodating space 104b provided below the receiving groove 104, the effect of sealing the lead wire is achieved.

[0031] Specifically, the main component 100 includes a shell 101, a through hole 102 extending through the outer wall of the shell 101, a half hole 103 extending through the outer wall of the shell 101, a notch 103a provided on the outer wall of the shell 101, a receiving groove 104 provided on the outer wall of the shell 101, a matching groove 104a provided below the receiving groove 104, and a receiving space 104b provided below the receiving groove 104; the fastening component 200 includes a pressing block 201, a blade 202 provided below the pressing block 201, an insert plate 203 provided below the pressing block 201, and a first inclined plate 203a and a second inclined plate 203b provided on the outer wall of the insert plate 203.

[0032] Preferably, grooves 101a are provided on the outer walls of both sides of the shell 101, and the half holes 103 are connected to the notches 103a.

[0033] Preferably, a first slideway 104c and a second slideway 104d are disposed in the accommodating space 104b, and the first slideway 104c and the second slideway 104d are centrally symmetrically arranged.

[0034] Among them, the through hole 102 and the half hole 103 extend from the outer wall of one side of the shell 101, through the matching groove 104a and the accommodating space 104b to the outer wall of the other side of the shell 101; the setting of the notch 103a facilitates the transformation of the cumbersome punching operation into a relatively simple operation of wrapping around the notch 103a; the accommodating groove 104 is used to place the pressing block 201; the top of the blade 202 is embedded in the pressing block 201, and the blade 202 is used to cut off the excess lead wire; the top of the plug plate 203 is embedded in the pressing block 201, and the plug plate 203 is arranged inside the accommodating space 104b; the first inclined plate 203a and the second inclined plate 203b are respectively fixedly connected to the outer wall of the plug plate 203. The design of the groove 101a is convenient for the staff to take the shell, and the half hole 103 is connected to the notch 103a, so that the lead wire can be wrapped around the notch 103a and placed inside the half hole 103.

[0035] In summary, when the seal is on delivery, the lead wire can be first inserted into the through hole 102 to reduce the trouble of threading on site. The staff pinches the grooves 101a on both sides of the shell 101, wraps one end of the lead wire around the notch 103a and into the half hole 103, and further presses the pressure block 201, the plug plate 203 moves downward, and the first inclined plate 203a and the second inclined plate 203b slide downward along the two inclined surfaces 104e in the first slide 104c and the second slide 104d respectively, so that the lead wire forms a "W" position and is fixed inside the accommodating space 104b.

[0036] Example 2, reference Figure 3 to Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, except that increasing the pressing force on the pressing block 201 can cause the blade 202 to cut off the excess lead wire.

[0037] Specifically, the inner wall of the accommodating space 104b is provided with two inclined surfaces 104e, and the tops of the first slideway 104c and the second slideway 104d are both provided with concave surfaces 104f.

[0038] Preferably, a blade 202a is provided below the blade 202, and the blade 202 is movably matched with the bottom of the matching groove 104a.

[0039] Preferably, the first inclined plate 203a and the second inclined plate 203b are slidably matched with the corresponding inclined surfaces 104e respectively.

[0040] Preferably, the first inclined plate 203a and the second inclined plate 203b are centrally symmetrically arranged.

[0041] Preferably, the first inclined plate 203a is slidably matched with the first slideway 104c, and the second inclined plate 203b is slidably matched with the second slideway 104d.

[0042] Among them, the lead wire is stainless steel wire or multi-strand steel-copper twisted wire; the blade can be made of high-temperature resistant plastic material, which will not deform at high temperatures above 90 degrees, will not support combustion and can be extinguished at a temperature of 650℃±10℃, or the plastic embedded stainless steel spring sheet is a corrosion-resistant material with good strength and elasticity; the two inclined surfaces 104e are respectively arranged above the first slide 104c and the second slide 104d, and the two inclined surfaces 104e are arranged symmetrically with the center; the blade 202 falls, which can press the blade 202a to the bottom of the matching groove 104a to cut the lead wire; the setting of the concave surface 104f realizes the locking effect of the plug plate 203, which can enable the plug plate 203 to withstand a tensile force of 60N without being pulled apart.

[0043] In summary, when the lead wire passes through the through hole 102 and the half hole 103 successively, the lead wire is stuck into the accommodating space 104b by pressing the pressure block 201, and further pressing force is applied to make the pressure block 201 completely fall into the accommodating groove 104. At this time, the blade 202 falls, and the blade 202a presses down to the bottom of the matching groove 104a to cut off the excess lead wire.

[0044] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention, provides a threading metering sealing method, including being able to expand the applicable population and reduce the impact of visual defects and old age on lead sealing work.

[0045] Specifically, the lead wire passes through the through hole 102 and the half hole 103 successively, and the pressing block 201 is pressed to lock the lead wire.

[0046] Preferably, the pressure is continuously applied, and the blade 202 is movably engaged with the bottom of the matching groove 104a to cut off the excess lead wire.

[0047] In summary, the lead seal sealing method is modified, the double-hole design is changed into a design of a through hole 102 and a notch 103a, and one side is modified into the notch 103a, and the cumbersome punching operation is modified into a relatively simple operation of surrounding into the notch 103a. The lead wire is pressed into the accommodating space 104 by the previous pressing method. At the same time, a matching groove 104a is added inside the lead seal to achieve cutting off of excess lead wire while pressing the seal, and jamming it in the accommodating space 104 to form a "W" position, which is more stable and anti-slip.
