Description

Technical Field

[0001] This invention relates to the field of electrophysiological shielding technology, and in particular to an electrophysiological shielding box for small animals to move freely. Background Technology

[0002] Currently, common electromagnetic shielding cabinets are bulky and occupy a large area.

The grounding device connects the mounting frame 101 and the metal mesh to ground the device, preventing small animals from being electrocuted and ensuring the overall potential of the device is zero. The sliding track 102a can be of various shapes, such as a ring, as long as it allows the movable wire clip 102b to move freely. The movable wire clip 102b consists of two parts: one part is set inside the sliding track 102a and slidably connected to it, and the other part is set below the sliding track 102a to fix the wire. The mounting frame 101 has mounting holes, the size of which is adapted to the rotating buckle 102c. The rotating buckle 102c and... The mounting holes are snap-fitted together, and each connecting component 103 is installed at one of the eight corners of the mounting frame 101.

The structure is a hollow cylinder. The outer wall of the fixed cylinder 103b-1 is provided with several sliding grooves 103b-3. The sliding grooves 103b-3 are connected to the accommodating cavity 103b-2. The clamping spring 103b-4 is located in the accommodating cavity 103b-2 at one end away from the base 103a. The two ends of the clamping spring 103b-4 are fixedly connected to the fixed cylinder 103b-1 and the slider 103c-1, respectively. The slider 103c-1 is adapted to the size of the accommodating cavity 103b-2 and slides in fit. The limiting block 103c-4 is adapted to the size of the sliding groove 103b-3 and slides in fit. One end of the pull rope 103d-1 is fixedly connected to the slider 103c-1, and the other end passes through the through groove and extends out of the fixed cylinder 103b-1. The steering rod 103d-2 is located between the slider 103c-1 and the fixed cylinder 103b-1 and can change the direction of force applied by the pull rope 103d-1.

[0035] Furthermore, the support assembly 201 includes a support frame 201a mounted on the mounting frame 101, connectors 201b at both ends of the support frame 201a, and a rotating component mounted on the support frame 201a. The winding assembly 202 includes a winding drum 202a mounted on the connectors 201b, a rotating rod 202b inside the winding drum 202a, a spring 202c at one end of the rotating rod 202b, and a double-layer metal mesh 202d mounted on the rotating rod 202b. The support frame 201a is mounted on the connectors 201b and fixed by the rotating component. The double-layer metal mesh 202d is fixedly connected to the rotating rod 202b and is wound around the rotating rod 202b. The spring 202c provides the power required for winding. The double-layer metal mesh 202d and the secondary metal mesh 402 are made of the same material, such as gold, silver, copper, aluminum, or steel, with a mesh count of 30-300 meshes.

[0036] Operation: In use, the sliding track 102a is installed on the top of the mounting frame 101. The wire is fixed to the top of the mounting frame 101 through the movable wire clip 102b. After being fixed by the wire clip, the wire hangs down and connects to the small animal. When the small animal moves around inside the mounting frame 101, the wire will drive the movable wire clip 102b to move along the sliding track 102a, so that the wire will not affect the small animal's movement. Since the wire is fixed to the top of the mounting frame 101, it can prevent the small animal from chewing on the wire. Several through holes are provided near each end of the mounting frame 101 for mounting the base 103a. Multiple bases 103a can be provided to support the mounting frame 101. Alternatively, two mounting and fixing winding assemblies 202 can be provided. During the fitting process of the base 103a, the fixing piece 103b on the base 103a will pass through the through hole. When passing through, the limiting block 103c-4 is pressed into the storage groove 103c-2 until the fixing cylinder 103b-1 is fully inserted. At this time, because the top spring 103b-4 keeps the limiting block 103c-4 pressed in the storage groove 103c-2, the pull rope 103d-1 extending out of the fixing cylinder 103b-1 is pulled. Since the top of the pull rope 103d-1 turns at the turning rod 103d-2, the pull rope 103d-1 can pull the slider 103c-1 inward. 1. Press the top spring 103b-4. At this time, due to the movement of the slider 103c-1, the limit block 103c-4 can slide out of the storage slot 103c-2. Then, release the pull rope 103d-1. The top spring 103b-4 will push the slider 103c-1 out again. As the slider 103c-1 moves outward, the bottom surface of the limit block 103c-4 can press against the mounting frame 101. When each base 103a is connected to the mounting frame 101, each mounting frame 101 and base 103a are fixed to each other. Then, the support frame 201a is placed at the edge of the mounting frame 101, the winding assembly 202 is installed on the support frame 201a, and the winding drum 202 is pulled out. The double-layer metal mesh 202d inside a is separated by the separating guide block 201b-1, covering the mounting frame 101 on both sides. When disassembly is required, pull the pull rope 103d-1 again until the slider 103c-1 is pulled to the top of the fixed cylinder 103b-1. The opening position of the slide groove is a certain distance from the top of the fixed cylinder 103b-1. During this process, the slider 103c-1 will be pressed back into the storage groove 103c-2 by the top of the slide groove. At the same time, pull out the three pull ropes 103d-1 of the base 103a. At this time, the base 103a can be pulled out. For convenient use, the ends of each pull rope 103d-1 that extend out of the fixed cylinder 103b-1 can be twisted together.

[0037] Example 2

[0038] Reference Figures 1-7The difference between this embodiment and the first embodiment is that the double-layer metal mesh 202d is adapted to the size of the mounting frame 101, one end of the double-layer metal mesh 202d is fixedly connected to the rotating rod 202b, and the double-layer metal mesh 202d and the secondary metal mesh 402 are made of the same material.

[0039] Specifically, the width of the double-layer metal mesh 202d is adapted to the winding drum 202a, and the bottom of the winding drum 202a has an opening for pulling out the double-layer metal mesh 202d. The length of the double-layer metal mesh 202d can completely cover the mounting frame 101.

[0040] Furthermore, the connector 201b includes a separation guide block 201b-1 connected to the clamping plate. The separation guide block 201b-1 has a separation groove 201b-2.

The separation protrusion 201b-3 is located in the center of the connector 201b and has a conical structure at the top.

[0041] Furthermore, the mounting assembly 301 includes a mounting bracket 301a disposed on the outer wall of the mounting frame 101, a protrusion 301b disposed on the mounting bracket 301a, and an elastic locking block 301c disposed on the protrusion 301b. The guiding assembly 302 includes a track 302a disposed on the mounting bracket 301a and a pull member 302b disposed on the double-layer metal mesh 202d. One surface of the mounting bracket 301a is in contact with the mounting frame 101. The protrusion 301b is adapted to the size and shape of the mounting hole. The elastic locking block 301c can be pressed into the protrusion 301b during installation. The track 302a and the connector 201b are on the same plane. The track 302a is adapted to the size and position of the separation slide 201b-2 and the guide slide 201b-4. The mounting ring 401 of the secondary metal mesh 402 is locked between the mounting frame 101 and the elastic locking block 301c, thereby fixing the secondary metal mesh 402.

[0042] The rest of the structure is the same as in the embodiment.

[0043] Operation process: When using, first fix the support frame 201a on the base 103a, install the winding drum 202a on the support frame 201a, then insert the protrusions 301b of each mounting bracket 301a into the mounting holes of the mounting frame 101, and fix them on the mounting frame 101 by the elastic clips 301c. The setting position and orientation of each mounting bracket 301a should be such that the track 302a corresponds to the separation slide 201b-2 and the guide slide 201b-4, and the mounting brackets 301a on both sides of the telescopic plate are symmetrically arranged.

[0044] Example 3

[0045] Reference Figure 7 This embodiment differs from the above embodiments in that: the pulling member 302b includes a rigid rod 302b-1 disposed at the top of the double-layer metal mesh 202d, a handle 302b-2 disposed on the rigid rod 302b-1, the handle 302b-2 including a connecting block 302b-2a disposed on the rigid rod 302b-1, a connecting buckle 302b-2b disposed on the connecting block 302b-2a, and a connecting slot 302b-2c opened on the connecting block 302b-2a.

[0046] Specifically, the length of the rigid rod 302b-1 is the same as the width of the metal mesh, the connecting block 302b-2a is located in the center of the rigid rod 302b-1, the diameter of the rigid rod 302b-1 is adapted to the separation slide 201b-2, the guide slide 201b-4 and the track 302a, the connecting buckle 302b-2b and the connecting slot 302b-2c are adapted to each other, the connecting blocks 302b-2a on the two metal meshes are set in the same position, but the connecting buckles 302b-2b and the connecting slots 302b-2c are set in opposite positions.

[0047] Furthermore, the rigid rod 302b-1 is adapted to and slidably connected with the separating groove 201b-2, and the rigid rod 302b-1 is adapted to and slidably connected with the track 302a. The connecting buckle 302b-2b is adapted to the size of the connecting slot 302b-2c. Pulling the handle 302b-2 allows the double-layer metal mesh 202d inside the take-up drum 202a to be pulled out through the rigid rod 302b-1. After being pulled out, both ends of the rigid rod 302b-1 enter the separating groove 201b-2. 01b-2 separates the double-layer metal mesh 202d into two single-layer metal meshes. Then, the rigid rod 302b-1 enters the guide groove 201b-4, passes through each track 302a in sequence, and finally converges directly below the mounting frame 101, thereby sealing the four sides of the mounting frame 101. The protrusion 301b is adapted to the size of the mounting hole, the elastic locking block 301c is engaged with the mounting frame 101, and the mounting ring 401 is sleeved on the protrusion 301b.

[0048] The rest of the structure is the same as in the embodiment.

[0049] Operation process: When in use, hold both handles 302b-2 simultaneously and pull out the double-layer metal mesh 202d. Send the rigid rod 302b-1 into the separation groove 201b-2 to separate the double-layer metal mesh 202d into two single-layer metal meshes. Then, they enter the two guide grooves 201b-4 and move in opposite directions. They are then guided and redirected through various tracks 302a, covering the mounting frame 101 until they meet at the bottom of the mounting frame 101. At this time, the connecting buckles 302b-2b on the two connecting blocks 302b-2a are inserted into the connecting slots 302b-2c on the other connecting block 302b-2a, thereby fixing the metal mesh. When disassembling, press the connecting buckles 302b-2b to disengage the two connecting blocks 302b-2a from each other. Under the action of the spring 202c, the double-layer metal mesh 202d is wound up.
