[0002] A welding electrode heat preservation container is a container for storing dried welding electrodes. It typically has a built-in power source for heating, maintaining the electrode temperature at around 100℃. This ensures the electrode coating remains dry and prevents welding defects caused by the coating absorbing moisture from the air during welding. Workers often forget to close the container after using the electrodes, leaving it open for extended periods and thus negating its heat preservation function. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model aims to provide a delayed reminder device for opening the cover of a welding rod cylinder. This device can emit an alarm sound after the welding rod cylinder has been opened for a certain period of time, so as to remind the operator to close the welding rod in time and ensure the heat preservation and storage capacity of the welding rod cylinder.

[0006] Preferably, there are two upper connecting rods and two lower connecting rods arranged in parallel; the lower ends of the two lower connecting rods are vertically fixed to a crossbar, and the sliding rod is rotatably connected to the middle of the crossbar.
[0007] Preferably, a first spring is sleeved on the slide rod, and the two ends of the first spring abut against the sleeve and the crossbar, respectively.
[0008] Preferably, a limiting block is fixed at the end of the slide rod inside the sleeve, and the diameter of the limiting block is larger than the opening diameter of the sleeve.
[0009] Preferably, the trigger switch assembly includes a first contact and a second contact. The first contact is mounted on the inner wall of the sleeve and is located near the sleeve opening. The second contact is mounted on the limiting block and is located corresponding to the first contact. The first and second contacts are connected to the two ends of a series circuit consisting of a battery, a delay control module, and a buzzer.
[0010] Preferably, the first contact piece is a long strip design and is positioned along the length of the sleeve near its opening.
[0011] Preferably, the latch assembly includes a latch, a rocker arm, a push rod, and a second spring. The top plate has a downward-facing lock hole corresponding to the lock lug. A groove is formed on the inner side of the lock hole. The rocker arm is vertically arranged and its middle part is rotatably connected in the groove. The latch is fixed at the top of the rocker arm near the lock hole and engages with the lock lug. The push rod is horizontally arranged with one end extending outward through the top plate and the other end abutting against the lower end of the rocker arm. The second spring is horizontally arranged at the lower end of the rocker arm away from the push rod, and its two ends abut against the rocker arm and the inner wall of the groove, respectively.

[0014] Preferably, the inner wall of the insulation cylinder is provided with an electric heating wire, and a temperature control module is provided in the insulation cylinder. The electric heating wire and the temperature control module are electrically connected to the battery.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. After the locking assembly of this application is unlocked, the locking lug on the cylinder cover disengages from the locking assembly. Under the action of the first spring, it can push the sliding rod to extend outward of the sleeve, thereby causing the two lower connecting rods to rotate counterclockwise around the central hinge point. Under the counterclockwise swing of the upper connecting rod, the right end of the cylinder cover flips to the left, while the left end of the cylinder cover flips upward, thereby causing the cylinder cover to flip open to the left of the top plate, opening the opening of the insulation cylinder for easy access to welding rods. When the cylinder cover is closed, pressing down on the cylinder cover causes the connecting rod and lower connecting rod to rotate clockwise. Under the swing limiting action of the upper and lower connecting rods, the cylinder cover can be locked downward at the opening and notch, achieving a seal on the insulation cylinder. The locking lug on the cylinder cover and the locking assembly on the top plate can lock the cylinder cover, achieving quick locking of the cylinder cover.
[0017] 2. When the cylinder cover is closed, the lower connecting rod swings to move the limiting block at the end of the slide rod to the leftmost end of the sleeve. At this time, the second contact on the limiting block is not in contact with the first contact inside the sleeve, and the series circuit consisting of the trigger switch assembly, the battery, the delay control module, and the buzzer is in an open state. When the cylinder cover is opened, the movement of the lower connecting rod moves the slide rod and the limiting block to the right, so that the second contact on the limiting block contacts the first contact, realizing the electrical conduction of the series circuit. At this time, the delay control module starts timing. If the cylinder cover is still not closed after the set time, the buzzer will sound an alarm to remind the operator to close the cylinder cover to ensure the heat preservation capacity of the welding rod cylinder.
[0018] 3. When using this application, the operator presses the cylinder cover downwards, causing the lock lug to extend into the lock hole and abut against the inclined surface above the lock tongue. The lock tongue is then pushed open to one side, and the swing rod rotates and swings around the central hinge point, compressing the second spring. Then, under the elastic force of the second spring, the swing rod rebounds, causing the lock tongue to engage with the lock lug's locking opening, thus locking the cylinder cover. When it is necessary to open the cylinder cover, the outer end of the push rod is pressed, causing the push rod to push the swing rod to rotate and compress the second spring. After the lock tongue disengages from the lock lug's locking opening, under the elastic force of the first spring, the cylinder cover will be opened to one side by swinging the lower and upper connecting rods, achieving a quick opening operation for the cylinder cover, which is very practical and convenient.

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.
[0025] like Figure 1-5As shown, this utility model proposes a delay reminder device for opening a welding rod cylinder, including an insulation cylinder 1 and a cylinder cover 12. A top plate 2 is horizontally fixed at the opening 11 above the insulation cylinder 1, and a bottom box 3 is connected and installed below the top plate 2 on one side of the insulation cylinder 1. A battery 43, a delay control module 41, and a buzzer 42 are installed inside the bottom box 3. The cylinder cover 12 is movably positioned above the opening 11, and an opening assembly is provided on the top plate 2. A notch 111 is provided on the side of the opening 11 of the top plate 2, and a lower connecting rod 52 is movably positioned in the notch 111 to provide movement space for the lower connecting rod 52. The shape of the cylinder cover 12 matches the shape formed by the opening 11 and the notch 111.
[0026] The cover opening assembly includes two upper connecting rods 51 and two lower connecting rods 52, which are arranged in parallel. The lower ends of the two L-shaped upper connecting rods 51 are rotatably connected to the top plate 2 on the left side of the opening 11, and the upper ends are rotatably connected to the left side of the top surface of the cover 12. The upper ends of the two lower connecting rods 52 are rotatably connected to the bottom surface of the cover 12 away from the upper connecting rods 51. The lower ends of the two lower connecting rods 52 extend downward into the notch 111, and the middle part of the two lower connecting rods 52 is rotatably connected to the notch 111 of the top plate 2. A horizontally arranged crossbar 53 is vertically fixed between the lower ends of the two lower connecting rods 52. A sleeve 541 and a sliding rod 542 are horizontally arranged inside the bottom box 3. The sliding rod 542 is slidably sleeved in the sleeve 541, and the tail of the sleeve 541 is rotatably connected to the bottom box 3. The end of the sliding rod 542 is rotatably connected to the middle of the crossbar 53. A first spring 543 is fitted onto the slide bar 542, and the two ends of the first spring 543 abut against the sleeve 541 and the crossbar 53, respectively. The first spring 543 provides elastic force for opening the cylinder cover 12. A locking lug 61 is installed on the cylinder cover 12, and a locking assembly that cooperates with the locking lug 61 is installed on the top plate 2.
[0027] After the locking assembly of this application is unlocked, the locking lug 61 on the cylinder cover 12 is released from the locking assembly. Under the elastic force of the first spring 543, it can push the slide rod 542 to extend outward of the sleeve 541, thereby driving the two lower connecting rods 52 to rotate counterclockwise around the central hinge point. Under the counterclockwise swing of the upper connecting rod 51, the right end of the cylinder cover 12 flips and moves to the left, while the left end of the cylinder cover 12 can flip and move upward, thereby causing the cylinder cover 12 to flip and open to the left of the top plate 2, opening the opening 11 of the heat preservation cylinder 1, which facilitates the taking and putting in of the welding rod. When the cover 12 is closed, the cover 12 can be pressed down, and the connecting rod and the lower connecting rod 52 can rotate clockwise. Under the swing limiting action of the upper connecting rod 51 and the lower connecting rod 52, the cover 12 can be locked down at the opening 11 and the notch 111, thus sealing the insulation cylinder 1. The cover 12 can be locked by the locking lug 61 on the cover 12 and the locking assembly on the top plate 2, thus achieving quick locking of the cover 12.
[0028] The sliding rod 542 has a limiting block 544 fixed at its end inside the sleeve 541. The diameter of the limiting block 544 is larger than the diameter of the opening 11 of the sleeve 541. The limiting block 544, which is slidably disposed inside the sleeve 541, can effectively limit the sliding rod 542, preventing it from disengaging from the sleeve 541 and improving its movement stability.
[0029] A trigger switch assembly is installed inside the sleeve 541. The trigger switch assembly includes a first contact 441 and a second contact 442. The first contact 441 is installed on the inner wall of the sleeve 541 and is elongated, positioned along the length of the sleeve 541 near its opening 11. The second contact 442 is installed on the limiting block 544 and corresponds to the first contact 441. The first and second contacts 441 are connected to the two ends of a time-delay alarm series circuit consisting of the battery 43, the time-delay control module 41, and the buzzer 42. Both contacts are conductive metal connecting pieces.
[0030] like Figure 4-5 As shown, when the cylinder cover 12 is closed, the lower connecting rod 52 swings, causing the limiting block 544 at the end of the slide rod 542 to move to the leftmost end of the sleeve 541. At this time, the second contact piece 442 on the limiting block 544 does not contact the first contact piece 441 inside the sleeve 541, and the series circuit consisting of the trigger switch assembly, the battery 43, the delay control module 41, and the buzzer 42 is in an open state. When the cylinder cover 12 is opened, the movement of the lower connecting rod 52 causes the slide rod 542 and the limiting block 544 to move to the right, so that the second contact piece 442 on the limiting block 544 contacts the first contact piece 441, realizing the electrical conduction of the series circuit. At this time, the delay control module 41 starts timing. If the cylinder cover 12 is still not closed after the set time is reached, the buzzer 42 will sound an alarm to remind the operator to close the cylinder cover 12 to ensure the heat preservation capacity of the welding rod cylinder.
[0031] The locking assembly includes a latch 621, a rocker arm 62, a push rod 64, and a second spring 63. A lock hole 21 corresponding to the lock lug 61 is provided on the top plate 2. A groove 22 is provided on the inner side of the lock hole 21. The rocker arm 62 is vertically arranged and its middle part is rotatably connected in the groove 22. The latch 621 is fixed on the top of the rocker arm 62 near the lock hole 21. The latch 621 cooperates with the lock opening 610 on the lock lug 61. The upper end of the latch 621 has an inclined surface that cooperates with the lock lug 61. When the lock lug 61 is pressed down to close, the inclined surface on the latch 621 can push the latch 621 and the rocker arm 62 to the side, so that the lock lug 61 can move downward and lock. The push rod 64 is horizontally positioned with one end extending outward through the top plate 2 and the other end abutting against the lower end of the swing rod 62. The second spring 63 is horizontally positioned on the lower end of the swing rod 62 away from the push rod 64, and the two ends of the second spring 63 abut against the swing rod 62 and the inner wall of the groove 22, respectively.
[0032] When using this application, the operator presses the cylinder cover 12 downwards, causing the locking lug 61 to extend into the lock hole 21 and abut against the inclined surface above the locking tongue 621. The locking tongue 621 is pushed open to one side, and the swing rod 62 rotates and swings around the central hinge point, compressing the second spring 63. Then, under the elastic force of the second spring 63, the swing rod 62 rebounds, causing the locking tongue 621 to engage with the locking lug 610, thus locking the cylinder cover 12. When it is necessary to open the cylinder cover 12, the outer end of the push rod 64 is pressed, causing the push rod 64 to push the swing rod 62 to rotate and compress the second spring 63. After the locking tongue 621 disengages from the locking lug 610, under the elastic force of the first spring 543, the lower connecting rod 52 and the upper connecting rod 51 swing together to open the cylinder cover 12 to one side, realizing the quick opening operation of the cylinder cover 12, which is very convenient and practical.
[0033] An electric heating wire 71 is provided on the inner wall of the insulation cylinder 1, and a temperature control module 72 is provided inside the insulation cylinder 1. The electric heating wire 71 and the temperature control module 72 are electrically connected to a battery 43. The temperature control module 72 is existing technology and may include a temperature sensor and a temperature control module. The temperature sensor can be installed on the inner wall of the insulation cylinder 1. The temperature control module 72 can be used to maintain a constant temperature inside the insulation cylinder 1.
[0034] When using this invention, the operator presses the outer end of the push rod 64. After the locking assembly and locking lug 61 are unlocked, the lower connecting rod 52 and the upper connecting rod 51 swing together under the elastic force of the first spring 543, opening the cylinder cover 12 to one side, thus achieving a quick opening operation. This is very convenient and practical. During the opening of the cylinder cover 12, the movement of the lower connecting rod 52 will drive the sliding rod 542 and the limiting block 544 to move to the right, causing the second contact piece 442 to contact the first contact piece 441, thus achieving electrical conduction of the series circuit. At this time, the delay control module 41 starts timing. If the cylinder cover 12 is not closed after the set time, the buzzer 42 will sound an alarm, reminding the operator to close the cylinder cover 12 to ensure the heat preservation capacity of the welding rod cylinder. When the operator closes the cylinder cover 12 downwards, the locking lug 61 extends into the lock hole 21 and cooperates with the locking assembly to achieve a quick locking of the cylinder cover 12.
