Abstract
The utility model relates to a new-type pinch device, which comprises three universal joints, left and right screw rods, a transmission rod and a pressing block. Universal joint I is connected with the left and right screw rods; the two screw elements in the left and right screw rods are respectively connected with two transmission rods; the two transmission rods are respectively connected with universal joint II and universal joint III; the universal joint II and universal joint III are respectively connected with two pressing blocks. The utility model, which features compact structure, simple manufacturing process, low cost, high reliability, convenient maintenance and easy application, can press tight several fixing points of a device by operating at one point, thus preventing the shortcoming of uneven stress at several points of the device due to uneven strain.
Description
Technical field
The utility model relates to a kind of novel hold down gag.
Background technique
Hold down gag big to general space and gadget has a variety of at present, but need install and be fixed in the cavity that has only one side perforate all the other five face closures for device, cavity is because space limited and under the several side of inside at all can't manual situation, solution to this type of problem mainly contains three kinds of methods: first kind is directly at the side of the cavity corresponding position skill mount inlet that goes into operation, and it is complicated and will destroy to some extent cavity to do technology like this; Second kind is to adopt the mode do transition bracket, earlier device is installed on the transition bracket, and it is fixing together then to be communicated with support, does the complexity that causes technology like this and has increased the weight of entire device; The third is to adopt hold down gag, only need possibly can't guarantee one man operation some immobilising device simultaneously for general hold down gag, thereby avoids because the firmly uneven bad defective that produces some unbalance stress of device.
Summary of the invention
The purpose of this utility model provides a kind of novel hold down gag.It only needs one man operation some immobilising device simultaneously, avoids because the firmly uneven defective that produces some unbalance stress of device.
The utility model is achieved like this, it comprises three Hooks coupling universal couplings, left and right sides screw rod, drive link, compact heap, it is characterized in that: Hooks coupling universal coupling I connects left and right sides screw rod, two helical members on the screw rod of the left and right sides connect two drive links respectively, two drive links connect Hooks coupling universal coupling II and Hooks coupling universal coupling III respectively, and Hooks coupling universal coupling II is connected two compact heaps respectively with Hooks coupling universal coupling III.
The utility model compact structure, manufacturing process is simple, with low cost, reliability is high, maintenance is good, implement easily, can utilize any method of operation to come simultaneously several immovable points of device are compressed, avoid because the firmly uneven bad defective that produces some unbalance stress of device, and can expand and utilize the mode of operation of any to compress favorable expandability simultaneously a plurality of devices.
Description of drawings
Fig. 1 is a work structuring schematic representation of the present utility model.
Hooks coupling universal coupling I 2, helical member 3, left and right sides screw rod 4, drive link 5, Hooks coupling universal coupling II 6, Hooks coupling universal coupling III 7, compact heap 8, device in the drawings 1,
Embodiment
As shown in Figure 1, Hooks coupling universal coupling I (1) connects left and right sides screw rod (3), two helical members (2) on the screw rod of the left and right sides connect two drive links (4) respectively, two drive links connect Hooks coupling universal coupling II (5) and Hooks coupling universal coupling III (6) respectively, two coupling connect two compact heaps (7) respectively, only need rotate Hooks coupling universal coupling I during use, drive left and right sides screw rod rotation, two helical member rotations on the screw rod of the left and right sides, drive two drive links around the rotation of separately gyration center, the compact heap that drives separately by universal-joint-pin type universal shaft coupling II and Hooks coupling universal coupling III oppositely compresses device (8) simultaneously.
