Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a fixing clamp for a temperature sensing cable. Background Art

[0002] The temperature sensing cable is a linear temperature sensing detector used in fire prevention construction to cooperate with fire warning. Compared with other temperature sensing fire detectors, it has good environmental adaptability, can be protected at close range or close to each other, and can work highly reliably in various fire detection places such as humid, polluted, and dusty. At present, the temperature sensing cable needs to be laid in parallel or in a sine wave shape according to the laying requirements during the laying process. The existing fixtures used in the laying process can only achieve simple positioning of the temperature sensing cable, and cannot further limit the position of the temperature sensing cable. If the temperature sensing cables come into contact with each other after laying, it may affect the accuracy of the subsequent temperature data detected by the temperature sensing cables. To this end, we propose a fixing fixture for the temperature sensing cable. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The utility model provides a technical solution: a fixing fixture for a temperature-sensing cable, comprising a first connecting block 1 and a second connecting block 2, wherein a connecting component 3 is assembled between opposite side walls of the first connecting block 1 and the second connecting block 2, and the first connecting block 1 and the second connecting block 2 are connected and fixed by the arranged connecting component 3, and the outer side walls of the first connecting block 1 and the second connecting block 2 are respectively fixedly connected with a clamping frame 5 which is symmetrically distributed in the front and rear through a connecting frame 4, and the clamping frame 5 is used to limit the position of the temperature-sensing cable.

[0020] This clamp is mainly used for the clamping and limiting of temperature sensing cables. Through this clamp, a certain distance can be maintained between the laid temperature sensing cables to avoid interference between the temperature sensing cables on both sides when the temperature sensing cables are used after laying, which will cause errors in temperature feedback.

[0021] like Figure 1 As shown in the figure, the connecting frame 4 is in a "Y-shape". By setting the connecting frame 4 in a "Y-shape", it has two connecting ends with the side walls of the first connecting block 1 and the second connecting block 2, thereby increasing the stability of the connection and fixation of the clamping frame 5 with the first connecting block 1 and the second connecting block 2.

[0022] The clamping frame 5 includes a clamping frame body 51, which is annular in shape. A clamping slot 52 is provided on the side wall of the clamping frame body 51. The clamping slot 52 is used for inserting the temperature sensing cable. The clamping frame body 51 is made of a deformable hard high-temperature resistant plastic material, so that the temperature sensing cable can be inserted and limited at the same time. The side wall of the clamping frame body 51 is integrally formed with a positioning frame 54 that is symmetrically distributed in the upper and lower parts. The positioning frame 54 is provided with a vertically distributed bending portion. By providing the positioning frame 54, the entire clamp can be supported when it is placed.

[0023] The inner ring side wall of the card-joint frame body 51 is evenly distributed with buffer bodies 53 in a circumferential manner. The buffer bodies 53 are arc-shaped and hollow and are made of high-temperature resistant rubber material. The temperature-sensitive optical cable in the card-joint frame body 51 is protected by providing the buffer bodies 53 evenly distributed in the circumference. When the temperature-sensitive optical cable moves in the card-joint frame body 51, its surface is buffered by the buffer bodies 53 to avoid direct contact between the temperature-sensitive optical cable and the card-joint frame body 51, and to avoid scratches and damage to the outer wall of the temperature-sensitive optical cable by the card-joint frame body 51, thereby affecting the signal transmission of the temperature-sensitive optical cable.

[0024] like Figure 2 and Figure 3As shown in the figure, the connecting component 3 includes a connecting cavity 31, which is opened in the first connecting block 1, and an assembly frame 32 is slidably connected in the connecting cavity 31. The side wall of the assembly frame 32 is fixedly connected to the side wall of the second connecting block 2 through a connecting shaft 33. A guide shaft 34 that passes through the assembly frame 32 is fixedly installed in the connecting cavity 31 in a front-to-back symmetrical manner. The outer side wall of the guide shaft 34 is sleeved with a spring 35, and the spring 35 is located between the assembly frame 32 and the connecting cavity 31. The side wall of the second connecting block 2 is fixedly connected with a clamping block 36, and the side wall of the first connecting block 1 is provided with an assembly groove 3 7. The relative positions of the first connection block 1 and the second connection block 2 are limited and fixed by the connection between the clamping block 36 and the assembly groove 37. The elastic force generated by the spring 35 on the assembly frame 32 keeps the first connection block 1 and the second connection block 2 in contact with each other. The connecting shaft 33 is composed of a connecting part and a rotating part. The connecting part is respectively connected and fixed to the side wall of the assembly frame 32 and the side wall of the second connection block 2. The rotating part is located between the connecting parts. The connecting shaft 33 can be rotated by the rotating part to adjust the relative position between the second connection block 2 and the first connection block 1.

[0025] The front and rear side walls of the first connecting block 1 and the second connecting block 2 are respectively integrally formed with anti-slip grooves 6. The anti-slip grooves 6 facilitate relative movement of the first connecting block 1 and the second connecting block 2 and facilitate angle adjustment of the second connecting block 2.

[0026] Working principle: Figure 4 and Figure 5 As shown in , this product has two usage modes. First, when the temperature-sensing cables are arranged in parallel positions, the clamp is evenly assembled along the laying line of the temperature-sensing cables. The temperature-sensing cables are respectively inserted into the clamping frames on both sides. The temperature-sensing cables can be limited and fixed through the clamping, and the distance between the temperature-sensing cables on both sides is maintained to avoid entanglement and contact between the temperature-sensing cables when the laying line is too long. When the temperature-sensing cables need to be arranged and laid along a sine wave pattern, one hand fixes the first connecting block 1, and the other hand pulls the second connecting block 2 to move the assembly frame 32 in the connecting cavity 31, compressing the spring 35. At this time, the clamping block 36 is disengaged from the assembly groove 37. After the second connecting block 2 is rotated, the second connecting block 2 is released, so that the assembly frame 32 is reset by the elastic force of the spring 35, so that the clamping block 36 is clamped with the assembly groove 37 again, and the relative position of the first connecting block 1 and the second connecting block 2 is fixed, and then as shown in Figure 5 As shown in the figure, the temperature sensing cables are supported and limited so that there is a certain distance between the crossed positions of the arranged temperature sensing cables to avoid contact between the temperature sensing cables.
