DETAILED DESCRIPTION

[0019] The technical scheme of the utility model will be described in detail and completely below according to the embodiment drawing of the utility model. Obviously, the described embodiment only represents a part of examples of the utility model, not all examples. Based on the embodiment of the utility model, all other examples that the person skilled in the art can obtain without creative labor belong to the protection scope of the utility model.

[0021] ReferenceFigure 1 The utility model relates to a kind of reusable detachable lead seal, its structure is consistent with prior art device, mainly by shell 1, seal 3 and limiting mechanism composition.

[0022] Specifically, shell 1 right side is designed with up-down axial accommodating hole 2, left side is provided with through-hole 4 passing through up-down. Seal 3 is vertical projection U-shaped structure, one end passes through through-hole 4, the other end passes through accommodating hole 2, so that the end close to accommodating hole 2 is located in the shell 1 interior and is fixed, and the other end of seal 3 can be moved to realize locking.

[0023] To ensure that seal 3 normally play a role, limiting mechanism is arranged in shell 1 interior, so that the movable end of seal 3 remains stable, realizes effective locking to object.

[0024] Referring to Figure 2 、 Figure 3 Unlike prior art device, the limiting mechanism in the device includes fixedly connected with shell 1 positioning plate 5, positioning plate 5 side is provided with driven plate 8, and seal 3 is located between the two, so, in actual operation, the distance between positioning plate 5 and driven plate 8 can be adjusted to realize the clamping of seal 3.

[0025] In addition, the end close to driven plate 8 and positioning plate 5 is connected with an elastic pad 18 respectively, and longitudinal anti-skid groove 16 is arranged on the elastic pad 18. The elastic pad 18 can play a buffering role when clamping seal 3, to avoid damage to seal 3. On the other hand, longitudinal anti-skid groove 16 can increase the friction between seal 3, to improve the stability of clamping.

[0026] Specifically, driven plate 8 and positioning plate 5 are connected by two connecting rods 6, and the two ends of each connecting rod 6 are rotatably connected with positioning plate 5 and driven plate 8 respectively. Meanwhile, the two connecting rods 6 and positioning plate 5 and driven plate 8 are projected together to form a parallelogram structure in the vertical plane. Under the premise that the position of positioning plate 5 remains unchanged, the distance between positioning plate 5 and driven plate 8 can be adjusted by rotating the connecting rod 6. During this process, the ends close to each other always remain parallel, ensuring that positioning plate 5, driven plate 8 and seal 3 have the maximum contact area, thereby effectively achieving stable clamping of seal 3.

[0027] It should be noted that the upper and lower ends of driven plate 8 are fixedly connected with driving rod 14 respectively, and sliding slot 17 is provided on shell 1 for driving rod 14. This design allows driving rod 14 to extend out of shell 1 along sliding slot 17, making it easy for the operator to drive driven plate 8 to move.

[0028] Further, the device is fixedly connected with the contact plate 7 at the distal end of the two driving rods 14, and the contact plate 7 is provided with the transverse anti-skid groove 15. The contact plate 7 facilitates the manual operation of the operator, and the transverse anti-skid groove 15 enhances the friction between the hand and the contact plate 7, so that the operator can more accurately control the movement of the driven plate 8.

[0029] Referring to Figure 2 、 Figure 4 In order to ensure that the distance between the driven plate 8 and the positioning plate 5 cannot be changed, and the two can always clamp and fix the sealing strip 3, the device is provided with the limiting plate 9 below the driven plate 8, which makes the driven plate 8 unable to move downward to increase the distance between the driven plate 8 and the positioning plate 5.

[0030] Correspondingly, the device is designed to be slidingly connected with the limiting plate 9 and the shell 1, and the position of the limiting plate 9 is changed by sliding left and right, that is, the cooperation relationship between the limiting plate 9 and the driven plate 8 is changed, so that when the limiting plate 9 moves to the lower side of the driven plate 8 and abuts against the driven plate 8, the distance between the positioning plate 5 and the driven plate 8 is less than the width of the sealing strip 3, thereby realizing the clamping and fixing of the sealing strip 3.

[0031] It should be pointed out that the device is provided with the magnetic drive mechanism 13 on one side of the limiting plate 9, and the limiting plate 9 can move linearly left and right inside the shell 1 through the magnetic drive mechanism 13. The magnetic drive mechanism 13 uses mature electromagnetic technology to control the generation of magnetic force through the energization and de-energization of the electromagnet, so as to attract or repel the limiting plate 9 and realize the linear movement of the limiting plate 9 in the left and right directions.

[0032] Further, in order to realize the sliding connection between the limiting plate 9 and the shell 1, the device is provided with the support seat 12 inside the shell 1, the support seat 12 is slidingly connected with the follow-up shaft 10, and the follow-up shaft 10 is fixedly connected with the limiting plate 9. The support seat 12 provides a stable sliding basis for the follow-up shaft 10, ensuring the stability of the limiting plate 9 during the sliding process.

[0033] Further, the device is provided with the compression spring 11 outside the follow-up shaft 10, and the two axial ends of the compression spring 11 abut against the limiting plate 9 and the support seat 12, respectively. The compression spring 11 provides a restoring force for the limiting plate 9 when the magnetic drive mechanism 13 stops acting, so as to return to the initial position.

[0034] It should be pointed out that the presence of the compression spring 11 enables the limiting plate 9 to automatically move to the lower side of the driven plate 8 to limit it after the operator of the device slides the driven plate 8 upward to achieve clamping and fixing of the seal 3, and this design enables the device to not need the participation of the magnetic driving mechanism 13 in the process of locking the specific object, and only needs the participation of the magnetic driving mechanism 13 in the process of unlocking the specific object, which meets the actual use requirement of the seal 3 and is convenient to operate.

[0035] In the actual application of the utility model, if the target object needs to be locked:

[0036] 1. The movable end of the seal 3 with a U-shaped structure projection is inserted into the appropriate position of the target object, and it is ensured that the movable end of the seal 3 can be inserted and protrude inside the through hole 4;

[0037] 2. The length of the movable end of the seal 3 extending out of the through hole 4 is adjusted to ensure that the locking effect meets the standard;

[0038] 3. The operator adjusts the contact plate 7 to move the driven plate 8 upward to shorten the distance from the positioning plate 5, and the limiting plate 9 abuts against the driven plate 8 after the compression spring 11 releases potential energy.

[0039] In the actual application of the utility model, if the target object needs to be unlocked:

[0040] 1. The corresponding operation equipment is used to match information with the magnetic driving mechanism 13 to ensure that the operation equipment can control the on-off of the magnetic driving mechanism 13;

[0041] 2. The operation equipment drives the magnetic mechanism to exert an axial pulling force on the driven shaft 10, and in this process, the compression spring 11 accumulates elastic potential energy. If the limiting plate 9 and the driven plate 8 are not coplanar, the seal 3 will exert a reverse force on the driven plate 8, forcing it to drop to the coplanar position with the limiting plate 9, at which time the clamping effect of the driven plate 8 and the positioning plate 5 on the seal 3 is cancelled;

[0042] 3. The operator pulls the middle part of the pull rope to smoothly separate the movable end from the through hole 4, thereby completing the unlocking operation of the target object.

[0043] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
