Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
As shown in fig. 1 to 3, an electric energy meter fixing device comprises a nail rod 501; one end of the nail rod 501 is provided with a plurality of elastic claws 502 which can be opened outwards; a nail sleeve 503 is connected outside the nail rod 501 in a sliding manner; one end of the nail sleeve 503 is externally threaded with a locking part 506, and the other end is detachably connected with a stabbing part 504; the length of the nail sleeve 503 is less than or equal to that of the nail rod 501.
Above-mentioned electric energy meter fixing device, during the installation, through elasticity jack catch 502 and locking portion 506 with ammeter installation department 4 and switchboard 1 are fixed, when needs are dismantled, through relaxing locking portion 506 to push down nail cover 503, thereby draw in elasticity jack catch 502, upwards pull out nail pole 501 and nail cover 503 together at last, can be with ammeter installation department 4 and switchboard 1 separation.
Specifically, the stabbing portion 504 is screwed to one end of the sleeve 503.
Specifically, in order to make the elastic claw 502 more smoothly folded by the pin sleeve 503, a transition fillet is provided at the inner edge of one end of the pin sleeve 503 close to the elastic claw 502.
Specifically, for the convenience of holding, one end of the nail rod 501 far away from the elastic claw 502 is connected with a nail cap 508.
Specifically, for the convenience of clamping, the end of the nail sleeve 503 away from the stabbing portion 504 is provided with two opposite plane clamping portions 505.
Specifically, in order to improve the connection strength, the connector further comprises a plurality of screws 507; one end of the screw 507 penetrates the locking portion 506 and is fastened and connected with the electricity meter mounting portion 4.
Example 2
As shown in fig. 4, compared with embodiment 1, an electric energy meter fixing device only changes the connection mode between the stabbing portion 504 and the nail sleeve 503. Specifically, the stabbing portion 504 is inserted into one end of the nail sleeve 503. Specifically, in order to smooth the wall of the hole, the outside diameter of the stabbing portion 504 is equal to the outside diameter of the sleeve 503.
The utility model discloses the theory of operation:
when the elastic claw is installed for the first time, the locking part 506 is installed on the nail sleeve 503, and then the nail sleeve 503 is sleeved on the nail rod 501, so that the elastic claw 502 is folded by the nail sleeve 503. The barbed portion 504 is attached to the other end of the sleeve 503 to complete the assembly of the fastener assembly 5. Then, the assembled fastening assembly 5 is put in place according to the position to be installed, the nail cap 508 is knocked, so that the nail rod 501, together with the nail sleeve 503 and the stabbing portion 504, gradually passes through the installation hole on the electricity meter installation portion 4, and the switchboard 1 is punched under the action of the stabbing portion 504.
After the punching is completed, the tapered portion 504 is removed, the nail cap 508 is pressed, the nail sleeve 503 is pulled upward, the nail sleeve 503 slides upward relative to the nail rod 501, and the binding of the elastic claw 502 by the nail sleeve 503 is completely released, so that the elastic claw 502 is scattered and clamped on the inner surface of the switchboard 1. Then, the flat holding portion 505 is held, and the locking portion 506 is screwed to contact and abut against the electricity meter mounting portion 4. Finally, the screw 507 is mounted to the locking portion 506 and the electricity meter mounting portion 4.
When the electric energy meter body 2 needs to be disassembled, the switchboard 1 does not need to be disassembled by taking down the fasteners 3. The electric energy meter body 2 and the electric meter mounting part 4 can be detached from the switchboard 1 only by taking down the screw 507, clamping the plane clamping part 505, rotating the locking part 506 to enable the locking part 506 to move upwards for a certain distance, then clamping the nail cap 508, pushing the locking part 506 and the nail sleeve 503 downwards to enable the nail sleeve 503 to slide downwards relative to the nail rod 501, collecting the elastic claw 502, and finally pulling out the nail sleeve 503 and the nail rod 501 together.
When it is necessary to install again, it is likewise not necessary to remove the switchboard 1. Compared with the first installation, the installation of the prick part 504 is omitted, so that the procedure of punching the switchboard 1 is omitted, and the installation of the electric energy meter body 2 can be completed.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
