Abstract
Description
Technical Field
[0001] The utility model relates to a completely insulated fixing structure and a palm vein access control host, belonging to the technical field of intelligent door locks. Background Art
[0002] At present, with the rapid economic development, various enterprises have been established, and the diversified office buildings have made office access control widely used. For different usage environments, door locks with plastic shells can no longer meet the conventional requirements, and the introduction of metal shells is becoming more and more frequent. However, the metal shell has strong conductivity. When static electricity or other currents act on the metal shell, the metal shell will conduct such currents to the relevant modules or components inside, resulting in the damage and failure of the corresponding modules or components.
[0003] To solve this problem, the following two solutions have emerged in the prior art:
[0004] 1. Fix the corresponding electronic module to the metal shell by screwing, and then export static electricity by connecting it to a metal bracket to make it grounded;
[0005] 2. Adopt a fixing method using insulating parts such as nylon studs. First, lock the insulating parts such as nylon studs to the metal shell, and then lock the corresponding electronic module to the insulating parts such as nylon studs to separate the corresponding electronic module from the metal shell.
[0006] In the first of the above solutions, when fixing by directly locking the corresponding electronic module to the metal shell and then grounding through a metal bracket, it is not completely insulated. Although it can achieve a certain insulation effect, when the current is too large, this method will fail. At the same time, due to the need to introduce a metal bracket, the use cost is relatively high. In the second solution, since the materials used for insulating parts such as nylon studs are mostly materials with poor rigidity such as plastics and rubbers, it is easy to break and slip during the locking process, which will have a great impact on the fixing effect. Summary of the Utility Model
[0007] In order to solve the above problems existing in the prior art, the utility model provides a completely insulated fixing structure and a palm vein access control host.
[0008] The technical solution of the utility model is as follows:
[0009] In a first aspect, the present utility model provides a completely insulated fixing structure, which includes an insulating sleeve. Inside the insulating sleeve, a first connecting member and a second connecting member are provided. There is a clearance between the first connecting member and the second connecting member. The bottom end of the first connecting member extends outwards from the bottom end of the insulating sleeve. The insulating sleeve can be connected to the outer shell of an external door lock through the first connecting member. A connecting screw is connected to the second connecting member, and the insulating sleeve can be connected to an external electronic module through the setting of the connecting screw.
[0010] Among them, the first connecting member includes a metal screw. The top head of the metal screw is fixedly arranged inside the insulating sleeve, and the tip of the metal screw extends out of the bottom of the insulating sleeve.
[0011] Among them, the second connecting member includes a metal nut. The metal nut is fixedly arranged inside the insulating sleeve, and the connecting screw is threadedly connected to the metal nut.
[0012] Among them, the insulating sleeve is arranged in a polygonal structure.
[0013] Among them, the insulating sleeve is made of rubber material or plastic material.
[0014] Among them, the height of the clearance is not less than 5 mm.
[0015] In a second aspect, the present utility model provides a palm vein access control host, which includes a metal shell. A placement groove is opened inside the metal shell. An electronic module is arranged in the placement groove. The host also includes a completely insulated fixing structure as described above. A connection hole adapted to the connecting screw is opened on the electronic module. A threaded hole adapted to the metal screw is opened in the placement groove. The electronic module is installed on the top surface of the insulating sleeve by threading the connecting screw through the connection hole and then threadedly connecting it into the metal nut. The bottom of the insulating sleeve is threadedly connected to the threaded hole through the metal screw to be connected to the placement groove together.
[0016] Among them, at least two of the completely insulated fixing structures are arranged in the placement groove. The arrangement of the threaded holes in the placement groove corresponds one-to-one to the completely insulated fixing structures. The insulating sleeve in each completely insulated fixing structure is connected to the corresponding threaded hole through a metal screw. The electronic module is connected to the insulating sleeve in each completely insulated fixing structure through the connecting screw.
[0017] The present utility model has the following beneficial effects:
[0018] The utility model realizes complete insulation by setting an insulating sleeve, arranging a first connecting piece and a second connecting piece inside the insulating sleeve, and cooperating with the arrangement of threaded holes and connecting screws. When installing the electronic module, the first connecting piece can connect the insulating sleeve to the placement groove through connection with the threaded hole, and the second connecting piece enables the electronic module to be connected to the insulating sleeve through connection with the connecting screw. With the reserved clearance, the electronic module can be installed in the placement groove without direct contact with the metal shell, thus achieving complete insulation without introducing a metal bracket for grounding insulation. At the same time, the first connecting piece and the second connecting piece have strong rigidity and are difficult to have problems such as thread stripping and fracture, which can well ensure the fixing effect. Compared with the prior art, it has the advantages of cost reduction, complete insulation, and good fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will describe the present utility model in detail with reference to the drawings and specific embodiments.
[0025] Embodiment 1: Please refer to Figures 1 to 3 , this embodiment provides a completely insulated fixing structure, including an insulating sleeve 1, which is made of common insulating materials, such as plastic materials, rubber materials, etc. A first connecting piece and a second connecting piece are arranged inside the insulating sleeve 1, and a clearance 2 is left between the first connecting piece and the second connecting piece, so that the first connecting piece and the second connecting piece cannot contact. The bottom end of the first connecting piece extends outwards from the bottom end of the insulating sleeve 1, and the insulating sleeve 1 can be connected to the shell of the external door lock through the first connecting piece. A connecting screw 3 is connected to the second connecting piece, and the insulating sleeve 1 can be connected to the external electronic module 4 through the arrangement of the connecting screw 3.
[0026] In this embodiment, the first connecting member includes a metal screw 5. The top head portion of the metal screw 5 is fixedly arranged inside the insulating sleeve 1, and the tip portion of the metal screw 5 extends out of the bottom of the insulating sleeve 1. The second connecting member includes a metal nut 6. The metal nut 6 is fixedly arranged inside the insulating sleeve 1, and the connecting screw 3 is threadedly connected with the metal nut 6.
[0027] With the above arrangement, when the fixing structure is in use, the insulating sleeve 1 is connected to the outer shell of the external door lock by using the metal screw 5. After that, the external electronic module 4 is installed on the top of the insulating sleeve 1 through the connection between the connecting screw 3 and the metal nut 6. At this time, the insulating sleeve 1 can separate the external electronic module 4 from the outer shell of the external door lock, avoiding direct contact and achieving an insulating effect. Due to the clearance 2 provided for the metal screw 5 and the metal nut 6 inside the insulating sleeve 1, there will be no contact between them, so no current will be conducted, thus achieving a completely insulating effect.
[0028] To facilitate the installation of the insulating sleeve 1, in this embodiment, the insulating sleeve 1 is arranged in a polygonal structure, preferably a hexagonal structure, so that the operator can use tools such as a wrench to grip the insulating sleeve 1 and rotate the insulating sleeve 1 to make the metal screw 5 move accordingly, thereby performing a tightening action.
[0029] To ensure the reliability of the insulation of the clearance 2, the height of the clearance 2 should be set to not less than 5 mm.
[0030] Embodiment Two: Please refer to Figures 1 to 3 , this embodiment provides a palm vein access control host, which includes a metal shell 7. A placement groove 8 is formed inside the metal shell 7. An electronic module 4 is arranged inside the placement groove 8. It also includes a completely insulating fixing structure provided in Embodiment One. A connection hole 9 adapted to the connecting screw 3 is formed on the electronic module 4. A threaded hole 10 adapted to the metal screw 5 is formed inside the placement groove 8. The electronic module 4 is installed on the top surface of the insulating sleeve 1 by threading the connecting screw 3 through the connection hole 9 and then threadedly connecting it into the metal nut 6. The bottom of the insulating sleeve 1 is threadedly connected into the threaded hole 10 by the metal screw 5 to be connected to the placement groove 8 together.
[0031] With the above settings, when installing the electronic module 4, the insulating sleeve 1 is threadedly connected to the threaded hole 10 through the metal screw 5 so that the insulating sleeve 1 can be fixedly arranged in the placement groove 8. Then, the electronic module 4 is placed on the top surface of the insulating sleeve 1. By using the connecting screw 3 to pass through the connecting hole 9 and then threadedly connecting it to the metal nut 6, the electronic module 4 is fixed to the insulating sleeve 1. At this time, the installation of the electronic module 4 is completed. Through the setting of the clearance 2 left between the insulating sleeve 1 and the metal screw 5 and the metal nut 6 inside the insulating sleeve 1, when the electronic module 3 is installed in the placement groove 8, it will not be in direct contact with the metal shell 7, so that complete insulation can be achieved without introducing a metal bracket for grounding insulation. At the same time, the metal screw 5 and the metal nut 6 have strong rigidity, making it difficult for them to have problems such as slipping teeth or breaking during the connection process with the threaded hole 10 and the connecting screw 9, so as to ensure the fixing effect.
[0032] To ensure the installation stability of the electronic module 4 in the placement groove 8, at least two such fixing structures are provided in the placement groove 8. The specific number can be determined according to the actual situation, so as to provide a corresponding number of support points for the electronic module 3. In this embodiment, the number of such fixing structures is two, and the two fixing structures are respectively arranged on both sides in the placement groove 8. The threaded holes 10 in the placement groove 8 are arranged in one-to-one correspondence with the insulating sleeves 1. The insulating sleeve 1 in each fixing structure is connected to the corresponding threaded hole 10 through the metal screw 5, and the electronic module 4 is connected to the insulating sleeve 1 in each fixing structure through the connecting screw 3. Through the above settings, the two fixing structures can provide support for the adjacent two end parts of the electronic module 4, so as to ensure the installation stability of the electronic module 4 in the placement groove 8 and ensure that the electronic module 4 is not prone to problems such as displacement and deformation.
[0033] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
