Example one

A mosaic instrument convenient to disassemble and assemble is shown in figures 1-3 and comprises a shell 1, a bottom cover 2 and a top cover 3.

The housing 1 is a rectangular casing (or a tubular structure, and the cross section may be circular or square), the top and bottom ends of which are open, and the circuit board 4 is fixed inside the housing by screws. The bottom end of the housing 1 is sealed by a bottom cover 2, the bottom cover and the housing are connected by screws, and the shape and size of the bottom cover 2 are completely identical to those of the bottom end of the housing 1. The top end of the shell 2 is sealed by a top cover 3, and the top end and the top cover are connected through an elastic buckle structure.

In this embodiment, the top end of the housing 1 is provided with two connecting plates 5, the two connecting plates 5 are symmetrically arranged, and correspondingly, the side wall of the top cover 3 is oppositely provided with connecting grooves 6 matched with the connecting plates 5. Meanwhile, a clamping joint 7 made of elastic materials, such as an elastic sheet, is arranged at the groove bottom of the connecting groove 6, the free end of the elastic sheet deviates from the shell 1, the clamping joint 7 is configured to protrude out of the groove bottom plane of the connecting groove 6 in a free state, and meanwhile, an accommodating groove used for accommodating the clamping joint 7 is formed in the connecting groove 6. Correspondingly, the connecting plate 5 is provided with a clamping hole 8 matched with the clamping joint 7.

It will be appreciated that the area of the cover 3 is not less than the size of the top opening of the housing 1, so that the cover 3 completely closes the housing 1, for example, with the outer side wall of the cover 3 being in direct alignment with the outer side wall of the housing 1. Meanwhile, the top cover 3 can be configured to be a solid body, after the bottom surface (the surface facing the shell 1) of the top cover is covered on the top end of the shell 1, the clamping connector 7 on the connecting groove 6 is matched with the clamping hole 8 on the connecting plate 5, so that the detachable fixed connection between the top cover 3 and the shell 1 is realized, and at the moment, the size of the available space in the shell 1 cannot be reduced because the top cover 3 is not embedded into the shell 1.

In this embodiment, the configuration circuit board 4 is connected with a signal lamp (not shown in the figure); correspondingly, top cap 3 includes the top cap body, sets up the logical groove of intercommunication shell 1 on this top cap body to the one end that leads to the groove and keep away from shell 1 is sealed there is light-passing board 9, so that the light that the signal lamp sent can transmit to the outside of shell 1. Wherein the size of the through groove does not exceed the inner section of the shell 1. At this time, the through groove in the top cover 3 communicates with the case 1, thereby further increasing the size of the available space of the meter.

In this embodiment, the bottom cover 2 is provided with a mounting hole, and the mounting hole is detachably and fixedly connected with a DP connector 10 electrically connected with the circuit board 4 through a VGA connector screw. In addition, in this embodiment, a ring of flange is provided at the end of the top cover 3 away from the housing 1 to facilitate the application of pulling force when removing the top cover 3.

The utility model discloses a theory of operation does: in the normal use process, after a signal is connected to the circuit board 4 through the DP connector 10, the signal lamp emits light and transmits the signal to the outside through the light-transmitting plate 9 on the top cover 3; when the instrument needs to be disassembled, the top cover 3 can be disassembled from the shell 1 only by pressing the clamping joint 7 to separate the clamping joint 7 from the clamping hole 8 on the connecting plate 5, and the bottom cover 2 only needs to disassemble a screw connected between the bottom cover and the shell 1; when the top cover 3 is installed, the top cover 3 and the shell 1 are close to each other only after the connecting plate 5 on the shell 1 is aligned to the connecting groove 6 on the top cover 3 until the clamping connector 7 is clamped into the clamping hole 8, and the bottom cover 2 is only required to be screwed on by screws. It can be seen that the top cover 3 and the housing 1 do not need to be embedded with each other due to the arrangement of the connecting plate 5 and the connecting groove 6, so that the total length of the instrument is substantially equal to the sum of the lengths of the housing 1 and the top cover 3, and a larger space in the instrument can be obtained under the same material.

Example two

In this embodiment, be provided with the guide way of the instrument installation of being convenient for on the lateral wall of shell 1, the guide way configuration is the structure that 1 outside surface of shell inwards caves in and forms, when the sunken degree of depth of guide way surpassed the inside wall of top cap 3, then made the condition of the inside and outside intercommunication of guide way with shell 1 appear, consequently need seal the processing to guide way.

One of them seals the processing scheme and is, be provided with on the inside wall of top cap 3 correspondingly with guide groove looks adaptation shutoff piece 11 to when top cap 3 and shell 1 interconnect, seal the guide groove through shutoff piece 11, thereby keep the sealed effect of shell 1. The block 11 is typically integrally formed on the top cover 3.

Another sealing processing scheme is that a sealing cover plate 12 is installed at the top end of the housing 1, so that the guide groove is sealed, the shape of the sealing cover plate 12 is the same as the cross-sectional shape of the guide groove, wherein a fixing pin is arranged on the surface of one side, facing the housing 1, of the sealing cover plate 12, and a pin hole is correspondingly formed in the top end of the housing 1, so that the sealing cover plate 12 is installed conveniently.

Of course, the two schemes can also be mixed. For example, in the present embodiment, the housing 1 and the top cover 3 are rectangular, the housing 1 and the top cover 3 each include two opposite first sidewalls and two opposite second sidewalls, the connecting plates 5 are symmetrically disposed on the two first sidewalls of the housing 1, and the connecting grooves 6 are correspondingly disposed on the two first sidewalls of the top cover 3. Wherein, the direction recess is including setting up the first direction recess in the outer wall corner of shell 1 and setting up the second direction recess on the second lateral wall of shell 1, and is corresponding, and the inner wall corner of top cap 3 is provided with the shutoff piece 11 with first direction recess looks adaptation, and 1 top of shell fixed mounting has the shutoff apron 12 that is used for sealing second direction recess. Wherein, the outside of two first lateral walls of configuration top cap 3 is aligned with the outside of two first lateral walls of shell 1 respectively, and the inboard of two second lateral walls of top cap 3 is aligned with the outside of two second lateral walls of shell 1 respectively, so set up for the second lateral wall of shell 1 and top cap 3 just staggers each other when keeping sealed, thereby makes shutoff apron 12 can not influence the installation of top cap 3.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
