Description
Technical field
The utility model relates to electrical equipment antiknock device technical field, refers more particularly to a kind of anti-explosion terminal box.
Background technology
Traditional armored cassette is generally made up of the connector cover coordinated up and down and junction box body two parts, is wherein provided with hermetically-sealed construction between connector cover and junction box body, concrete for be formed with groove along flange face circumference on the flange face of connector cover side, and sealing ring is placed with in groove, the side of corresponding respective slot on junction box body is formed with seal bead, by the compression fit of seal bead and groove and then form hermetically-sealed construction during use, although traditional above-mentioned hermetically-sealed construction possesses certain sealing effectiveness, but due to seal bead and groove is all that cooperation division surface by being arranged on connector cover and junction box body is formed, when it runs into the impact of outside water or dust, it is not ideal that its sealing effectiveness just becomes.
For this reason, some manufacturers start to attempt releasing the version that some sealing effectivenesss stablize effective anti-explosion terminal box more, such as Authorization Notice No. is the Chinese utility model patent of " a kind of high leakproofness anti-explosion terminal box " of CN202602200U (day for announcing is on December 12nd, 2012), in order to reach excellent sealing effectiveness, it is by being provided with the lateral wall to downward-extension in cover rim, and upper cover bottom surface is also provided with the madial wall to downward-extension near the position of lateral wall, between above-mentioned lateral wall and madial wall, is formed with sealed groove; Position lower house corresponding to above-mentioned sealed groove is provided with seal bead, during use by sealing convex tendon and sealed groove compression fit realize sealing effectiveness, simultaneously also be provided with at least one elastic seal ring between the medial surface of seal bead and the lateral surface of madial wall, although this kind of hermetically-sealed construction form can well realize the sealing effectiveness of terminal box, but its structure is too complicated, concrete for being embodied in the madial wall of upper cover on it and the processing and making process difficulty of lateral wall on the one hand, undoubtedly to the production cost that enterprise increases; Be embodied in the installment work of elastic seal ring on the other hand, the operation easier of operator in practical operation can be increased equally, and then reduce production efficiency; To this, for how to find, a kind of structure is simple effectively can ensure that the anti-explosion terminal box structure of sealing effectiveness just seems particularly important simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure simple, operate easy for installation while effectively can ensure the anti-explosion terminal box of sealing effectiveness.
For achieving the above object, technical scheme provided by the utility model is: a kind of anti-explosion terminal box, comprise upper end cover and lower house, described upper end cover is smooth coverboard structure, wherein this upper end cover end face four end is respectively arranged with the through hole for mounting screw, this upper end cover bottom surface also offers the square mounting groove for installing sealing strip, sealing bar is bonded and fixed in this square mounting groove by fluid sealant; The described lower house upper surface four end also one-body molded contiguous block having horizontal-extending to the periphery respectively, contiguous block upper surface described in each is also provided with the joint pin being threaded hole be connected with the through hole corresponding matching on described upper end cover, this lower house bottom four end also one-body molded mount pad having horizontal-extending to the periphery respectively, mount pad described in each also offers the U-shaped draw-in groove by the locking of screw clamping; When described upper end cover and lower house are compressed by screw lock, the mid portion of the upper surface of described lower house on it and sealing strip fit compress and be positioned at simultaneously sealing bar on it two side portions of middle part also fit with the upper surface outboard sidewalls of described lower house respectively.
Further, described lower housing cavity bottom face surrounding is also provided with location hole, and wherein said location hole is also connected with lower housing cavity sidewall by the reinforcement be provided with.
The version that this programme is matched by the upper end cover and lower house adopting smooth coverboard version, wherein this upper end cover bottom surface also offers the square mounting groove for installing sealing strip, and sealing strip is fixedly mounted in this square mounting groove by the mode that fluid sealant is bonding, when upper end cover and lower house are compressed by screw lock, the mid portion of the upper surface of lower house on it and sealing strip fits and compresses and be positioned at the sealing bar version that the two side portions of middle part also fits with the upper surface outboard sidewalls of lower house respectively on it simultaneously, due to the coverboard structure that upper end cover is smooth, therefore its processing and fabricating is simple, the square mounting groove that its bottom offers simultaneously is convenient to processing and fabricating equally, and sealing strip is to be fixedly mounted in above-mentioned square mounting groove by the mode of fluid sealant, it is installed simply and easily its installation fixed effect simultaneously and is also guaranteed, in addition, during compression, the mid portion of the upper surface of the lower house in this programme on it and sealing strip fits and compresses and be positioned at the sealing bar version that the two side portions of middle part also fits with the upper surface outboard sidewalls of lower house respectively on it simultaneously, thus effectively can ensure sealing effectiveness.
