Description

Technical Field

[0001] The utility model relates to an optical cable joint box, in particular to a self-adjusting fastening and sealing type cap-type optical cable joint box. Background Technique

[0002] When installing the existing cap-type joint box, it is necessary to forcefully push the edge of the connection seal between the cylinder body and the base into the clamping groove of the hoop, and then lock the hoop through the locking bolts at both ends to complete the fixed connection between the cylinder body and the base and achieve the sealing effect.

[0003] However, during the installation process, the cap-type joint box often has problems with the size of the clamping groove of the hoop due to material shrinkage and mold problems, resulting in uneven compression force on the upper and lower and around the seal by the hoop, causing differential deformation and resulting in sealing problems. For this reason, a self-adjusting fastening and sealing type cap-type optical cable joint box is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to propose a self-adjusting fastening and sealing type cap-type optical cable joint box to solve the above problems.

[0006] Further preferably, the front end of the hoop is provided with teeth, and the edges of the cylinder body and the base corresponding to the positions are also provided with teeth.

[0007] Further preferably, a limiting structure for limiting the position of the sealing rubber ring is also arranged between the base and the cylinder body.

[0008] Further preferably, the limiting structure includes a sealing groove arranged on the base and the cylinder body, a limiting ring arranged on the base and the cylinder body, and a limiting ring groove arranged on the sealing rubber ring and adapted to the limiting ring.

[0009] Further preferably, it further includes a locking bolt for locking the hoop.

[0010] Advantages of the present utility model: By adding an elastic seal in the clamping groove of the hoop, when the hoop is used to lock the connection between the base and the cylinder, the elastic seal can adaptively compensate for dimensional deviations, so that when the base and the cylinder are locked, the connection can be squeezed comprehensively, and the compression amount can be adjusted adaptively according to the squeezing force received during squeezing, so that the force on the connection is uniform, avoiding differential deformation caused by uneven force, and thus improving the sealing effect.

[0011] By setting teeth at the port of the clamping groove of the hoop, first, it is to limit the elastic seal within the hoop to prevent it from slipping out; second, when the hoop is initially installed on the cylinder and the base, it is pre-installed by cooperating with the edge teeth provided on the cylinder and the base. After pre-installation, the operator does not need to hold it by hand, avoiding the hoop falling off the cylinder and the base before installing the bolts. After both half hoops are pre-installed at the connection of the cylinder and the base, the two half hoops are locked by bolts to complete the installation connection of the cylinder and the base. The installation is simple, convenient, fast, and has high installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, we will further explain a self-adjusting fastening and sealing type cap optical cable splice closure according to the present utility model with reference to the accompanying drawings.

[0018] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indications will also change accordingly.

[0019] In the present utility model, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] Referring to Figures 1-4 As shown in , a self-adjusting fastening and sealing type cap optical cable joint box includes a base 1, a cylinder body 2 installed on the base 1, and a hoop 3 for fixedly connecting the base 1 and the cylinder body 2. It is characterized in that it further includes a sealing rubber ring 4 arranged between the cylinder body 2 and the base 1 for the sealing between the base 1 and the cylinder body 2, and an elastic sealing body 5 installed in the hoop 3 for adjusting the force on the connection between the base 1 and the cylinder body 2 when the hoop 3 acts on the base 1 and the cylinder body 2 to make the force on the connection between the base 1 and the cylinder body 2 uniform.

[0021] By adding an elastic sealing body 5 in the card slot of the hoop 3, when locking the connection between the base 1 and the cylinder body 2 through the hoop 3, an adaptive compensation is formed for the size deviation through the elastic sealing body 5, so that when locking the base 1 and the cylinder body 2, the connection can be squeezed in all aspects and the compression amount can be adaptively adjusted according to the squeezing force received during squeezing, so that the force on the connection is uniform, avoiding differential deformation caused by uneven force, and thus improving the sealing effect.

[0022] In one embodiment, the front end of the hoop 3 is provided with a card tooth 6, and corresponding edge card teeth 7 are also provided on the cylinder body 2 and the base 1.

[0023] By setting the card tooth 6 at the port of the card slot of the hoop 3, on the one hand, it plays a limiting role for the elastic sealing body 5 in the hoop 3 to prevent it from coming out; on the other hand, when initially installing the hoop 3 on the cylinder body 2 and the base 1, it is pre-installed by cooperating with the edge card teeth 7 provided on the cylinder body 2 and the base 1. After pre-installation, the operator does not need to hold it by hand to avoid the hoop 3 falling off the cylinder body 2 and the base 1 before installing the bolts. After both half hoops 3 are pre-installed at the connection of the cylinder body 2 and the base 1, locking the two half hoops 3 through bolts completes the installation connection of the cylinder body 2 and the base 1. The installation is simple, convenient, fast, and has high installation efficiency.

[0026] Through the arrangement of the sealing ring and the sealing groove 8, the position of the sealing rubber ring 4 in the sealing groove 8 is limited, and at the same time, the sealing performance is enhanced.

[0027] In one embodiment, it further includes a locking bolt 11 for locking the hoop 3; the hoop 3 is composed of two half-hoops 3, and the two half-hoops 3 are locked and connected through the locking bolt 11.

[0028] When the utility model is installed: First, install the sealing rubber ring 4 in the sealing groove 8 of the base 1, and make the limiting ring 9 in the sealing groove 8 engage with the limiting ring groove 10 of the sealing rubber ring 4. Then, install the cylinder body 2 on the base 1. When installing, make the other end of the sealing rubber ring 4 be in the sealing groove 8 of the cylinder body 2, and make the limiting ring 9 engage with the limiting ring groove 10. Then, install the elastic sealing body 5 into the hoop 3.
