Description

Technical Field

[0001] The present invention belongs to the technical field of seal accessories, and particularly relates to a seal clamping device. Background Art

[0002] With the development of communication technology, intelligent seals with network communication functions have gradually come into people's sight. Through the supporting seal management system, the situation of seal abuse can be effectively avoided, remote approval of paper documents can be carried out, and at the same time, electronic documents can be generated from the content of paper documents for archiving, which not only improves the approval efficiency but also improves the security of seal use. And intelligent seals are generally designed based on the conventional ones, especially the head part of the seal is installed with a special seal clamping device. The existing clamping device usage methods are as follows: 1. Measure the size of the seal, customize the clamping device by machining, mechanically cut the seal to form a fixed thickness, stick it on the clamping device with 3M glue or AB glue, and then fix the clamping device together with the seal to the intelligent seal bracket with screws; 2. Make clamping devices with multiple standard size coverage ranges, cooperate with gaskets of various diameters and thicknesses to wrap the seal to achieve the function of clamping the seal, and then hang the clamping device together with the seal inside the intelligent seal through the form of threads behind the clamping device.

[0003] The above-mentioned seal clamping devices have the following deficiencies: high service cost, measuring the size of the seal on-site by service personnel to customize the clamping device and mechanically cutting the seal surface and installing it with glue both require service personnel to be on-site, resulting in high service cost; troublesome installation, even if making clamping devices with multiple size coverage ranges, users still need to first select a suitable clamping device according to the seal in their hands, then select a suitable gasket, and then tighten it through various spiral structures, which is still a bit difficult for office clerks and the operation is troublesome; it is not convenient to replace the clamping device and the seal. Currently, the form of installing the clamping device on the intelligent seal cylinder is either screwed tightly or fixed with screws. When it comes to replacing the clamping device or the seal, tools are needed and certain operation skills are required to achieve it. Summary of the Invention

[0043] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0045] Next, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein.

[0046] Embodiment 1

[0047] Please refer to the attached Figures 1 to 4 As shown, this is the first embodiment of the present invention. This embodiment provides a seal fixture device applied to an intelligent seal. Usually, an intelligent seal is generally designed based on convention. It can be a fixture customized by machining or a fixture covering multiple sizes can be made. In this application, the seal fixture device includes:

[0048] A fixed end 1, with a movable end 2 hinged on the fixed end 1, and a locking mechanism is provided at the opening and closing part between the movable end 2 and the fixed end 1. Among them, when the movable end 2 and the fixed end 1 are locked, a cylindrical structure is formed;

[0049] Positioning members 4, which are respectively assembled on the inner sides of the fixed end 1 and the movable end 2. And when the movable end 2 and the fixed end 1 are locked, the two positioning members 4 are spliced together to form a funnel structure and fix the seal body;

[0050] Among them, the wall thickness of the positioning member 4 can gradually decrease from the inside to the outside

[0051] In the above embodiment, through the positioning member 4 with a variable wall thickness, the fixture can be used for seals of various specifications. And when the positioning member 4 clamps the seal, the funnel structure formed by its splicing can hold the handle of the seal, playing a further stabilizing effect.

[0052] In addition, since the handle lengths or the thicknesses of the head parts of seals of different specifications are different, resulting in deviations in the waist positions of the seals, and conventional fixtures cannot be adjusted in real time according to their positions, which will lead to a deterioration in the clamping effect on the seals. Therefore, this application also designs a positioning mechanism 6 for adjusting the height of the positioning member 4 so that the height of the positioning member 4 can be adjusted according to the height of the seal handle. Specifically, positioning mechanisms 6 for fixing the positioning member 4 are provided on both the fixed end 1 and the movable end 2. By adjusting the positioning mechanism 6, the height of the positioning member 4 can be adjusted. Through the positioning mechanism 6, the height of the positioning member 4 can be adjusted, and thus the positioning member 4 can be used for seals of different heights, with a wider applicability.

[0053] Among them, the above-mentioned positioning mechanism 6 includes a plurality of locking holes 601a, and at least one of the locking holes 601a is internally provided with a self-tapping screw 602a, and the self-tapping screw 602a extends into the interior of the positioning member 4 to fix the positioning member 4.

[0054] During the actual adjustment process, the height of the rear positioning member 4 can be adjusted, and then by using the self-tapping screw 602a to pass through the corresponding locking hole 601a, the self-tapping screw 602a is screwed into the interior of the positioning member 4 to achieve the locking effect. In addition, to meet the locking requirements, corresponding threaded holes are provided on the positioning member 4.

[0055] In one embodiment, please refer to Figure 4 , the positioning member 4 is a rubber support 401a, and a plurality of hollow areas 402a are provided on the rubber support 401a. Among them, the hollow areas 402a can be sequentially removed from the inside to the outside.

[0056] In this embodiment, when clamping the seal, generally the handle of the seal is clamped, and the shape of the handle is basically similar, that is, the diameter of the waist of the handle is smaller than the upper and lower parts. For clamping this part of the seal, it is preferred to clamp the waist. Specifically, when the present application clamps the seal, the waist of the handle can be directly placed inside the rubber support 401a. When the movable end 2 and the fixed end 1 are locked, the rubber support 401a clamps the waist of the handle. Due to the design of the hollow area 402a, when locked, the rubber support 401a is deformed under pressure, so that the rubber support 401a can better clamp the handle. Secondly, the funnel structure formed when the rubber support 401a closes can also lift the head of the handle, so that the clamping effect of the seal is better. Most importantly, when the diameter of the waist of the seal changes greatly, the hollow area 402a can be directly torn off gradually from the inside to the outside, so that the inner diameter of the rubber support 401a decreases when it is combined, and then it can be used for seals with a larger diameter of the handle. Its operation method is very simple, without any tools, and only needs to be torn off directly by hand.

[0057] In one of the preferred embodiments, the thickness of each hollow area 402a is preferably 20 mm, and the material of the rubber support 401a is preferably easily torn silicone.

[0058] In addition, please refer to again Figure 1 , the locking mechanism includes a barb tooth 71 provided on the movable end 2 and a tooth 72 provided on the fixed end 1. When the fixed end 1 is docked with the movable end 2, the barb tooth 71 is engaged with the tooth 72, and the movable end 2 and the fixed end 1 are unlocked through a lock switch 73. When the seal needs to be taken out, press the dot of the lock switch, and under the action of the internal tension, the barb tooth is released, and the movable end 2 automatically pops open, and the seal can be taken off. When installing the seal, after placing the seal, the movable end 2 and the fixed end 1 are fixed by using the lock switch. At this time, under the engagement of the tooth and the barb tooth, the overall engagement effect is better.

[0059] Among them, the latch switch 73 is a pressing area integrally formed on the fixed end 1, and this pressing area is located above the teeth. When the movable end 2 is locked with the fixed end 1, the barbed teeth will be stuck on the teeth, thus realizing locking. When it is necessary to remove the seal, press the pressing area 73. At this time, the pressing area will be squeezed inward and deformed, so that the tooth part will deform inward. At this time, the teeth are separated from the barbed teeth, and quick disassembly can be realized. Here, the whole fixed end 1 is made of plastic material, so it can drive the end part of the fixed end 1 to deform when pressed.

[0060] An ink inlet 5 is assembled at the bottom of the fixed end 1. Positioning protrusions are provided on both sides of the ink inlet 5, and the positioning protrusions are adapted to the tracks arranged inside the seal cylinder, and are used to limit the whole fixture to prevent the fixture from deflecting.

[0061] Further, please refer to Figure 10 , and a retaining ring 5a is also provided inside the ink inlet 5. The retaining ring 5a is used to block the upper part of the seal head to prevent the seal from shifting upward when applying the seal subsequently. And because the seal surface thicknesses of different seals are inconsistent, and the currently commonly used specification is that the seal surface is 19.5 mm thick, this seal surface can perfectly fit this fixture. However, there are still some seals whose seal surface thickness is less than this seal surface thickness. Therefore, in order to prevent the retaining ring 5a from being unable to block the seal surface, a rubber ring 5b is placed below the retaining ring 5a. The rubber ring 5b is sleeved on the seal handle of the seal and contacts the upper part of the seal surface. Due to the addition of the rubber ring 5b, the upper part of the seal surface is thickened, and thus can be blocked by the retaining ring 5a. And the rubber ring 5b has a variety of specifications and can be customized according to different specifications of the seal head, with a wider selection. In addition, for the specification of the ink inlet, it should be greater than 57.5 mm, and the inner diameter of the retaining ring 5a should be less than 22 mm and greater than 20 mm. The purpose of this design is to be able to accommodate most of the seals on the current market. Its inner diameter is less than 22 mm, which enables the retaining ring 5a to accommodate most of the seals with a seal surface width of more than 22 mm and less than 57.5 mm.

[0062] The seal fixture device further includes a locking part 3. The locking part 3 is assembled at the tail of the fixed end 1 and is used to assemble the cylindrical structure into the seal cylinder of the intelligent seal. The locking part 3 includes a tail end cover 301, and a groove buckle 302 is provided on the tail end cover 301. The groove buckle 302 is adapted to the electric control lock inside the cylinder.

[0063] During specific use, when the seal cylinder is locked, the electric control lock is adapted to the groove buckle 302 to realize the locking of the whole fixture. When performing the operation of changing the seal, by controlling the electric control lock, its servo rotates, and the steering wheel ejects the hook, that is, it is separated from the groove buckle 302. At this time, the fixture is separated under the action of gravity, and the disassembly is very convenient.

[0064] The present invention also provides an intelligent seal, including:

[0065] Seal cylinder;

[0066] Seal clamp device;

[0067] And, an electric control lock, which is assembled inside the seal cylinder, and the seal clamp device is fixed inside the seal cylinder by the electric control lock.

[0068] Among them, the seal cylinder and the electric control lock are both standard components of current intelligent seals, so they are not shown in the figure. After adopting the seal clamp device, the clamp replacement of the intelligent seal becomes simpler and more convenient. Compared with conventional seals, it greatly reduces the operation difficulty and does not require additional tool operation.

[0069] Embodiment 2

[0070] This embodiment is a further improvement based on Embodiment 1, and its difference from Embodiment 1 lies only in the positioning member 4.

[0071] Please refer to Figures 4 to 6 , the positioning member 4 includes a plurality of arc-shaped rubber sheets 401b. The heights of the plurality of arc-shaped rubber sheets 401b increase sequentially from the inside to the outside and are spliced into a semi-circular ring shape. Among them, a first sliding groove 402b is formed on the inner side of the arc-shaped rubber sheet 401b. The first sliding groove 402b has a first side wall and two symmetrical second side walls. A first protrusion 403b adapted to the first sliding groove 402b is provided on the outside of the arc-shaped rubber sheet 401b. Among them, the two side edges of the first protrusion 403b are in interference fit with the second side walls, and a gap is provided between the end of the first protrusion 403b and the first side wall. Resistance increasing members are provided on both the end of the first protrusion 403b and the first side wall, and when the innermost arc-shaped rubber sheet 401b clamps the seal body, the end of the first protrusion 403b abuts against the first side wall.

[0072] In this embodiment, it is composed of multiple arc-shaped rubber sheets 401b that can slide relative to each other. During actual adjustment, the position of the arc-shaped rubber sheets 401b can be adjusted. The specific working principle is similar to that of a telescopic sleeve, and it can change the funnel shape formed according to the specifications of the seal handle head. Moreover, no tools are required for the adjustment process. Since all are made of rubber materials, there will be a sense of damping during the sliding process of the arc-shaped rubber sheets 401b, that is, it has a preliminary positioning effect. After the adjustment is completed, when the seal is clamped, the innermost arc-shaped rubber sheet 401b is squeezed and transmitted outward in sequence, causing the arc-shaped rubber sheets 401b to be extruded outward. At this time, the first protrusion 403b will abut against the increasing component, thereby achieving a better fixing effect, and this fixing process does not require manual control, making it more convenient to use. When applying seal handles with different inner diameters, since the movable end 2 is in an open state, that is, the arc-shaped rubber sheets 401b no longer have the squeezing effect, the arc-shaped rubber sheets 401b can be removed conveniently and quickly without any tools. The most crucial thing is that the arc-shaped rubber sheets 401b removed in this way can be reused repeatedly, with better practicability.

[0073] It should be noted that the gap between the increasing component and the first protrusion 403b should be designed to be small enough, which is set to not more than 5 mm here. A structure similar to a serration can also be added to the opposite side of the increasing component and the first protrusion 403b to make the fixing effect better.

[0074] Embodiment 3

[0075] This embodiment is a further improvement based on Embodiment 1 or 2, and the only difference from Embodiment 1 or 2 lies in the different positioning mechanism 6.

[0076] Please refer to Figures 7 to 9 , the positioning mechanism 6 includes second chutes 601b respectively opened on the fixed end 1 and the movable end 2, and sliders 602b sliding inside the second chutes 601b. On the side of the slider 602b facing the rubber support 401a, there is a "barb"-shaped second protrusion 603b, and the second protrusion 603b is in interference fit with the groove body opened on the side of the positioning member 4. Among them, on the other side of the slider 602b, there is an extrusion block 604b arranged through a locking bolt. The inner side of the extrusion block 604b is provided with serrations, and there are also multiple serrations evenly distributed on the fixed end 1 and the movable end 2.

[0077] In this embodiment, through the second protrusion 603b provided, the positioning member 4 can be stuck on the second protrusion 603b through the groove on it, thereby realizing rapid assembly. At the same time, when it is necessary to adjust the height of the positioning member 4, the locking bolt can be loosened, and then the slider 602b can be slid up and down along the second chute 601b. When adjusted to the required height, tighten the locking bolt so that the teeth on the extrusion block 604b abut against the teeth on the fixed end 1 or the movable end 2, thereby realizing the effect of rapidly adjusting the height of the positioning member.

[0078] Further, the cross-section of the second chute 601b is cross-shaped, and the cross-section of the slider 602b is also cross-shaped. The purpose of adopting this design is to enable the slider 602b to be stuck inside the second chute 601b without detachment. At the same time, a counterbore is provided on one side of the second chute 601b close to the extrusion block 604b, and the extrusion block 604b sinks into the counterbore, and the teeth of the fixed end 1 and the movable end 2 are arranged inside the counterbore.

[0079] The working principle of the present invention is as follows: through the positioning member 4 whose wall thickness can be changed, the fixture can be used for various specifications of seals. When the positioning member 4 clamps the seal, the funnel structure formed by its splicing can hold the handle of the seal, playing a further stabilizing effect. The overall structure of the positioning member 4 is simple, and disassembly and maintenance are convenient. Especially when disassembling and assembling the seal, no other tools are required, and general clerical staff can operate it. In addition, during actual use, the height of the positioning member 4 can also be adjusted according to the actual situation, making its applicability wider.

[0080] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special instructions and limitations.
